text: Cell polarity is a fundamental feature of all multicellular organisms. In
plants, prominent cell polarity markers are PIN auxin transporters crucial for
plant development. To identify novel components involved in cell polarity establishment
and maintenance, we carried out a forward genetic screening with PIN2:PIN1-HA;pin2
Arabidopsis plants, which ectopically express predominantly basally localized
PIN1 in the root epidermal cells leading to agravitropic root growth. From the
screen, we identified the regulator of PIN polarity 12 (repp12) mutation, which
restored gravitropic root growth and caused PIN1-HA polarity switch from basal
to apical side of root epidermal cells. Complementation experiments established
the repp12 causative mutation as an amino acid substitution in Aminophospholipid
ATPase3 (ALA3), a phospholipid flippase with predicted function in vesicle formation.
ala3 T-DNA mutants show defects in many auxin-regulated processes, in asymmetric
auxin distribution and in PIN trafficking. Analysis of quintuple and sextuple
mutants confirmed a crucial role of ALA proteins in regulating plant development
and in PIN trafficking and polarity. Genetic and physical interaction studies
revealed that ALA3 functions together with GNOM and BIG3 ARF GEFs. Taken together,
our results identified ALA3 flippase as an important interactor and regulator
of ARF GEF functioning in PIN polarity, trafficking and auxin-mediated development.

text: Clathrin-mediated endocytosis (CME) and its core endocytic machinery are evolutionarily
conserved across all eukaryotes. In mammals, the heterotetrameric adaptor protein
complex-2 (AP-2) sorts plasma membrane (PM) cargoes into vesicles through the
recognition of motifs based on tyrosine or di-leucine in their cytoplasmic tails.
However, in plants, very little is known on how PM proteins are sorted for CME
and whether similar motifs are required. In Arabidopsis thaliana, the brassinosteroid
(BR) receptor, BR INSENSITIVE1 (BRI1), undergoes endocytosis that depends on clathrin
and AP-2. Here we demonstrate that BRI1 binds directly to the medium AP-2 subunit,
AP2M. The cytoplasmic domain of BRI1 contains five putative canonical surface-exposed
tyrosine-based endocytic motifs. The tyrosine-to-phenylalanine substitution in
Y898KAI reduced BRI1 internalization without affecting its kinase activity. Consistently,
plants carrying the BRI1Y898F mutation were hypersensitive to BRs. Our study demonstrates
that AP-2-dependent internalization of PM proteins via the recognition of functional
tyrosine motifs also operates in plants.

text: The TPLATE complex (TPC) is a key endocytic adaptor protein complex in plants.
TPC in Arabidopsis (Arabidopsis thaliana) contains six evolutionarily conserved
subunits and two plant-specific subunits, AtEH1/Pan1 and AtEH2/Pan1, although
cytoplasmic proteins are not associated with the hexameric subcomplex in the cytoplasm.
To investigate the dynamic assembly of the octameric TPC at the plasma membrane
(PM), we performed state-of-the-art dual-color live cell imaging at physiological
and lowered temperatures. Lowering the temperature slowed down endocytosis, thereby
enhancing the temporal resolution of the differential recruitment of endocytic
components. Under both normal and lowered temperature conditions, the core TPC
subunit TPLATE and the AtEH/Pan1 proteins exhibited simultaneous recruitment at
the PM. These results, together with co-localization analysis of different TPC
subunits, allow us to conclude that TPC in plant cells is not recruited to the
PM sequentially but as an octameric complex.

text: In this paper we introduce and study all-pay bidding games, a class of two
player, zero-sum games on graphs. The game proceeds as follows. We place a token
on some vertex in the graph and assign budgets to the two players. Each turn,
each player submits a sealed legal bid (non-negative and below their remaining
budget), which is deducted from their budget and the highest bidder moves the
token onto an adjacent vertex. The game ends once a sink is reached, and Player
1 pays Player 2 the outcome that is associated with the sink. The players attempt
to maximize their expected outcome. Our games model settings where effort (of
no inherent value) needs to be invested in an ongoing and stateful manner. On
the negative side, we show that even in simple games on DAGs, optimal strategies
may require a distribution over bids with infinite support. A central quantity
in bidding games is the ratio of the players budgets. On the positive side, we
show a simple FPTAS for DAGs, that, for each budget ratio, outputs an approximation
for the optimal strategy for that ratio. We also implement it, show that it performs
well, and suggests interesting properties of these games. Then, given an outcome
c, we show an algorithm for finding the necessary and sufficient initial ratio
for guaranteeing outcome c with probability 1 and a strategy ensuring such. Finally,
while the general case has not previously been studied, solving the specific game
in which Player 1 wins iff he wins the first two auctions, has been long stated
as an open question, which we solve.

text: Cell production and differentiation for the acquisition of specific functions
are key features of living systems. The dynamic network of cellular microtubules
provides the necessary platform to accommodate processes associated with the transition
of cells through the individual phases of cytogenesis. Here, we show that the
plant hormone cytokinin fine‐tunes the activity of the microtubular cytoskeleton
during cell differentiation and counteracts microtubular rearrangements driven
by the hormone auxin. The endogenous upward gradient of cytokinin activity along
the longitudinal growth axis in Arabidopsis thaliana roots correlates with robust
rearrangements of the microtubule cytoskeleton in epidermal cells progressing
from the proliferative to the differentiation stage. Controlled increases in cytokinin
activity result in premature re‐organization of the microtubule network from transversal
to an oblique disposition in cells prior to their differentiation, whereas attenuated
hormone perception delays cytoskeleton conversion into a configuration typical
for differentiated cells. Intriguingly, cytokinin can interfere with microtubules
also in animal cells, such as leukocytes, suggesting that a cytokinin‐sensitive
control pathway for the microtubular cytoskeleton may be at least partially conserved
between plant and animal cells.

text: Origin and functions of intermittent transitions among sleep stages, including
brief awakenings and arousals, constitute a challenge to the current homeostatic
framework for sleep regulation, focusing on factors modulating sleep over large
time scales. Here we propose that the complex micro-architecture characterizing
sleep on scales of seconds and minutes results from intrinsic non-equilibrium
critical dynamics. We investigate θ- and δ-wave dynamics in control rats and in
rats where the sleep-promoting ventrolateral preoptic nucleus (VLPO) is lesioned
(male Sprague-Dawley rats). We demonstrate that bursts in θ and δ cortical rhythms
exhibit complex temporal organization, with long-range correlations and robust
duality of power-law (θ-bursts, active phase) and exponential-like (δ-bursts,
quiescent phase) duration distributions, features typical of non-equilibrium systems
self-organizing at criticality. We show that such non-equilibrium behavior relates
to anti-correlated coupling between θ- and δ-bursts, persists across a range of
time scales, and is independent of the dominant physiologic state; indications
of a basic principle in sleep regulation. Further, we find that VLPO lesions lead
to a modulation of cortical dynamics resulting in altered dynamical parameters
of θ- and δ-bursts and significant reduction in θ–δ coupling. Our empirical findings
and model simulations demonstrate that θ–δ coupling is essential for the emerging
non-equilibrium critical dynamics observed across the sleep–wake cycle, and indicate
that VLPO neurons may have dual role for both sleep and arousal/brief wake activation.
The uncovered critical behavior in sleep- and wake-related cortical rhythms indicates
a mechanism essential for the micro-architecture of spontaneous sleep-stage and
arousal transitions within a novel, non-homeostatic paradigm of sleep regulation.

text: We consider a dilute, homogeneous Bose gas at positive temperature. The system
is investigated in the Gross–Pitaevskii limit, where the scattering length a is
so small that the interaction energy is of the same order of magnitude as the
spectral gap of the Laplacian, and for temperatures that are comparable to the
critical temperature of the ideal gas. We show that the difference between the
specific free energy of the interacting system and the one of the ideal gas is
to leading order given by 4πa(2ϱ2−ϱ20). Here ϱ denotes the density of the system
and ϱ0 is the expected condensate density of the ideal gas. Additionally, we show
that the one-particle density matrix of any approximate minimizer of the Gibbs
free energy functional is to leading order given by the one of the ideal gas.
This in particular proves Bose–Einstein condensation with critical temperature
given by the one of the ideal gas to leading order. One key ingredient of our
proof is a novel use of the Gibbs variational principle that goes hand in hand
with the c-number substitution.

text: We study the dynamics of a system of N interacting bosons in a disc-shaped
trap, which is realised by an external potential that confines the bosons in one
spatial dimension to an interval of length of order ε. The interaction is non-negative
and scaled in such a way that its scattering length is of order ε/N, while its
range is proportional to (ε/N)β with scaling parameter β∈(0,1]. We consider the
simultaneous limit (N,ε)→(∞,0) and assume that the system initially exhibits Bose–Einstein
condensation. We prove that condensation is preserved by the N-body dynamics,
where the time-evolved condensate wave function is the solution of a two-dimensional
non-linear equation. The strength of the non-linearity depends on the scaling
parameter β. For β∈(0,1), we obtain a cubic defocusing non-linear Schrödinger
equation, while the choice β=1 yields a Gross–Pitaevskii equation featuring the
scattering length of the interaction. In both cases, the coupling parameter depends
on the confining potential.

text: "For 1≤m≤n, we consider a natural m-out-of-n multi-instance scenario for a
public-key encryption (PKE) scheme. An adversary, given n independent instances
of PKE, wins if he breaks at least m out of the n instances. In this work, we
are interested in the scaling factor of PKE schemes, SF, which measures how well
the difficulty of breaking m out of the n instances scales in m. That is, a scaling
factor SF=ℓ indicates that breaking m out of n instances is at least ℓ times more
difficult than breaking one single instance. A PKE scheme with small scaling factor
hence provides an ideal target for mass surveillance. In fact, the Logjam attack
(CCS 2015) implicitly exploited, among other things, an almost constant scaling
factor of ElGamal over finite fields (with shared group parameters).\r\n\r\nFor
Hashed ElGamal over elliptic curves, we use the generic group model to argue that
the scaling factor depends on the scheme's granularity. In low granularity, meaning
each public key contains its independent group parameter, the scheme has optimal
scaling factor SF=m; In medium and high granularity, meaning all public keys share
the same group parameter, the scheme still has a reasonable scaling factor SF=√m.
Our findings underline that instantiating ElGamal over elliptic curves should
be preferred to finite fields in a multi-instance scenario.\r\n\r\nAs our main
technical contribution, we derive new generic-group lower bounds of Ω(√(mp)) on
the difficulty of solving both the m-out-of-n Gap Discrete Logarithm and the m-out-of-n
Gap Computational Diffie-Hellman problem over groups of prime order p, extending
a recent result by Yun (EUROCRYPT 2015). We establish the lower bound by studying
the hardness of a related computational problem which we call the search-by-hypersurface
problem."

text: We introduce the monitoring of trace properties under assumptions. An assumption
limits the space of possible traces that the monitor may encounter. An assumption
may result from knowledge about the system that is being monitored, about the
environment, or about another, connected monitor. We define monitorability under
assumptions and study its theoretical properties. In particular, we show that
for every assumption A, the boolean combinations of properties that are safe or
co-safe relative to A are monitorable under A. We give several examples and constructions
on how an assumption can make a non-monitorable property monitorable, and how
an assumption can make a monitorable property monitorable with fewer resources,
such as integer registers.

text: 'A simple drawing D(G) of a graph G is one where each pair of edges share
at most one point: either a common endpoint or a proper crossing. An edge e in
the complement of G can be inserted into D(G) if there exists a simple drawing
of G+e extending D(G). As a result of Levi’s Enlargement Lemma, if a drawing
is rectilinear (pseudolinear), that is, the edges can be extended into an arrangement
of lines (pseudolines), then any edge in the complement of G can be inserted.
In contrast, we show that it is NP -complete to decide whether one edge can
be inserted into a simple drawing. This remains true even if we assume that the
drawing is pseudocircular, that is, the edges can be extended to an arrangement
of pseudocircles. On the positive side, we show that, given an arrangement of
pseudocircles A and a pseudosegment σ , it can be decided in polynomial time
whether there exists a pseudocircle Φσ extending σ for which A∪{Φσ} is
again an arrangement of pseudocircles.'

text: "We introduce the notion of Witness Maps as a cryptographic notion of a proof
system. A Unique Witness Map (UWM) deterministically maps all witnesses for an
\ NP statement to a single representative witness, resulting in a computationally
sound, deterministic-prover, non-interactive witness independent proof system.
A relaxation of UWM, called Compact Witness Map (CWM), maps all the witnesses
to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive
proof-system. We also define a Dual Mode Witness Map (DMWM) which adds an “extractable”
mode to a CWM.\r\nOur main construction is a DMWM for all NP relations, assuming
sub-exponentially secure indistinguishability obfuscation ( iO ), along with
standard cryptographic assumptions. The DMWM construction relies on a CWM and
a new primitive called Cumulative All-Lossy-But-One Trapdoor Functions (C-ALBO-TDF),
both of which are in turn instantiated based on iO and other primitives. Our
instantiation of a CWM is in fact a UWM; in turn, we show that a UWM implies Witness
Encryption. Along the way to constructing UWM and C-ALBO-TDF, we also construct,
from standard assumptions, Puncturable Digital Signatures and a new primitive
called Cumulative Lossy Trapdoor Functions (C-LTDF). The former improves up on
a construction of Bellare et al. (Eurocrypt 2016), who relied on sub-exponentially
secure iO and sub-exponentially secure OWF.\r\nAs an application of our constructions,
we show how to use a DMWM to construct the first leakage and tamper-resilient
signatures with a deterministic signer, thereby solving a decade old open problem
posed by Katz and Vaikunthanathan (Asiacrypt 2009), by Boyle, Segev and Wichs
(Eurocrypt 2011), as well as by Faonio and Venturi (Asiacrypt 2016). Our construction
achieves the optimal leakage rate of 1−o(1) ."

text: We consider a system of N bosons in the limit N→∞, interacting through singular
potentials. For initial data exhibiting Bose–Einstein condensation, the many-body
time evolution is well approximated through a quadratic fluctuation dynamics around
a cubic nonlinear Schrödinger equation of the condensate wave function. We show
that these fluctuations satisfy a (multi-variate) central limit theorem.

text: The biotic interactions hypothesis posits that biotic interactions are more
important drivers of adaptation closer to the equator, evidenced by “stronger”
contemporary interactions (e.g. greater interaction rates) and/or patterns of
trait evolution consistent with a history of stronger interactions. Support for
the hypothesis is mixed, but few studies span tropical and temperate regions while
experimentally controlling for evolutionary history. Here, we integrate field
observations and common garden experiments to quantify the relative importance
of pollination and herbivory in a pair of tropical‐temperate congeneric perennial
herbs. Phytolacca rivinoides and P. americana are pioneer species native to the
Neotropics and the eastern USA, respectively. We compared plant‐pollinator and
plant‐herbivore interactions between three tropical populations of P. rivinoides
from Costa Rica and three temperate populations of P. americana from its northern
range edge in Michigan and Ohio. For some metrics of interaction importance, we
also included three subtropical populations of P. americana from its southern
range edge in Florida. This approach confounds species and region but allows us,
uniquely, to measure complementary proxies of interaction importance across a
tropical‐temperate range in one system. To test the prediction that lower‐latitude
plants are more reliant on insect pollinators, we quantified floral display and
reward, insect visitation rates, and self‐pollination ability (autogamy). To test
the prediction that lower‐latitude plants experience more herbivore pressure,
we quantified herbivory rates, herbivore abundance, and leaf palatability. We
found evidence supporting the biotic interactions hypothesis for most comparisons
between P. rivinoides and north‐temperate P. americana (floral display, insect
visitation, autogamy, herbivory, herbivore abundance, and young‐leaf palatability).
Results for subtropical P. americana populations, however, were typically not
intermediate between P. rivinoides and north‐temperate P. americana, as would
be predicted by a linear latitudinal gradient in interaction importance. Subtropical
young‐leaf palatability was intermediate, but subtropical mature leaves were the
least palatable, and pollination‐related traits did not differ between temperate
and subtropical regions. These nonlinear patterns of interaction importance suggest
future work to relate interaction importance to climatic or biotic thresholds.
In sum, we found that the biotic interactions hypothesis was more consistently
supported at the larger spatial scale of our study.

text: "* Morphogenesis and adaptive tropic growth in plants depend on gradients
of the phytohormone auxin, mediated by the membrane‐based PIN‐FORMED (PIN) auxin
transporters. PINs localize to a particular side of the plasma membrane (PM) or
to the endoplasmic reticulum (ER) to directionally transport auxin and maintain
intercellular and intracellular auxin homeostasis, respectively. However, the
molecular cues that confer their diverse cellular localizations remain largely
unknown.\r\n* In this study, we systematically swapped the domains between ER‐
and PM‐localized PIN proteins, as well as between apical and basal PM‐localized
PINs from Arabidopsis thaliana , to shed light on why PIN family members with
similar topological structures reside at different membrane compartments within
cells.\r\n* Our results show that not only do the N‐ and C‐terminal transmembrane
domains (TMDs) and central hydrophilic loop contribute to their differential subcellular
localizations and cellular polarity, but that the pairwise‐matched N‐ and C‐terminal
TMDs resulting from intramolecular domain–domain coevolution are also crucial
for their divergent patterns of localization.\r\n* These findings illustrate the
complexity of the evolutionary path of PIN proteins in acquiring their plethora
of developmental functions and adaptive growth in plants."

text: This paper introduces a simple method for simulating highly anisotropic elastoplastic
material behaviors like the dissolution of fibrous phenomena (splintering wood,
shredding bales of hay) and materials composed of large numbers of irregularly‐shaped
bodies (piles of twigs, pencils, or cards). We introduce a simple transformation
of the anisotropic problem into an equivalent isotropic one, and we solve this
new “fictitious” isotropic problem using an existing simulator based on the material
point method. Our approach results in minimal changes to existing simulators,
and it allows us to re‐use popular isotropic plasticity models like the Drucker‐Prager
yield criterion instead of inventing new anisotropic plasticity models for every
phenomenon we wish to simulate.

text: Water-in-salt electrolytes based on highly concentrated bis(trifluoromethyl)sulfonimide
(TFSI) promise aqueous electrolytes with stabilities approaching 3 V. However,
especially with an electrode approaching the cathodic (reductive) stability, cycling
stability is insufficient. While stability critically relies on a solid electrolyte
interphase (SEI), the mechanism behind the cathodic stability limit remains unclear.
Here, we reveal two distinct reduction potentials for the chemical environments
of ‘free’ and ‘bound’ water and that both contribute to SEI formation. Free-water
is reduced ~1V above bound water in a hydrogen evolution reaction (HER) and responsible
for SEI formation via reactive intermediates of the HER; concurrent LiTFSI precipitation/dissolution
establishes a dynamic interface. The free-water population emerges, therefore,
as the handle to extend the cathodic limit of aqueous electrolytes and the battery
cycling stability.

text: Coinfections with multiple pathogens can result in complex within‐host dynamics
affecting virulence and transmission. While multiple infections are intensively
studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defences of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal pathogen
species. Social immunity reduced virulence for all pathogen combinations, but
interfered with spore production only in different‐species coinfections. Here,
it decreased overall pathogen sporulation success while increasing co‐sporulation
on individual cadavers and maintaining a higher pathogen diversity at the community
level. Mathematical modelling revealed that host sanitary care alone can modulate
competitive outcomes between pathogens, giving advantage to fast‐germinating,
thus less grooming‐sensitive ones. Host social interactions can hence modulate
infection dynamics in coinfected group members, thereby altering pathogen communities
at the host level and population level.

text: Sewall Wright developed FST for describing population differentiation and
it has since been extended to many novel applications, including the detection
of homomorphic sex chromosomes. However, there has been confusion regarding the
expected estimate of FST for a fixed difference between the X‐ and Y‐chromosome
when comparing males and females. Here, we attempt to resolve this confusion by
contrasting two common FST estimators and explain why they yield different estimates
when applied to the case of sex chromosomes. We show that this difference is true
for many allele frequencies, but the situation characterized by fixed differences
between the X‐ and Y‐chromosome is among the most extreme. To avoid additional
confusion, we recommend that all authors using FST clearly state which estimator
of FST their work uses.

text: 'Habitat loss is one of the key drivers of the ongoing decline of biodiversity.
However, ecologists still argue about how fragmentation of habitat (independent
of habitat loss) affects species richness. The recently proposed habitat amount
hypothesis posits that species richness only depends on the total amount of habitat
in a local landscape. In contrast, empirical studies report contrasting patterns:
some find positive and others negative effects of fragmentation per se on species
richness. To explain this apparent disparity, we devise a stochastic, spatially
explicit model of competitive species communities in heterogeneous habitats. The
model shows that habitat loss and fragmentation have complex effects on species
diversity in competitive communities. When the total amount of habitat is large,
fragmentation per se tends to increase species diversity, but if the total amount
of habitat is small, the situation is reversed: fragmentation per se decreases
species diversity.'

text: We show the synthesis of a redox‐active quinone, 2‐methoxy‐1,4‐hydroquinone
(MHQ), from a bio‐based feedstock and its suitability as electrolyte in aqueous
redox flow batteries. We identified semiquinone intermediates at insufficiently
low pH and quinoid radicals as responsible for decomposition of MHQ under electrochemical
conditions. Both can be avoided and/or stabilized, respectively, using H 3 PO
4 electrolyte, allowing for reversible cycling in a redox flow battery for hundreds
of cycles.

text: Coinfections with multiple pathogens can result in complex within-host dynamics
affecting virulence and transmission. Whilst multiple infections are intensively
studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defenses of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal
pathogen species. Social immunity reduced virulence for all pathogen combinations,
but interfered with spore production only in different-species coinfections. Here,
it decreased overall pathogen sporulation success, whilst simultaneously increasing
co-sporulation on individual cadavers and maintaining a higher pathogen diversity
at the community-level. Mathematical modeling revealed that host sanitary care
alone can modulate competitive outcomes between pathogens, giving advantage to
fast-germinating, thus less grooming-sensitive ones. Host social interactions
can hence modulate infection dynamics in coinfected group members, thereby altering
pathogen communities at the host- and population-level.

text: The hippocampus plays key roles in learning and memory and is a main target
of Alzheimer's disease (AD), which causes progressive memory impairments. Despite
numerous investigations about the processes required for the normal hippocampal
functions, the neurotransmitter receptors involved in the synaptic deficits by
which AD disables the hippocampus are not yet characterized. By combining histoblots,
western blots, immunohistochemistry and high‐resolution immunoelectron microscopic
methods for GABAB receptors, this study provides a quantitative description of
the expression and the subcellular localization of GABAB1 in the hippocampus in
a mouse model of AD at 1, 6 and 12 months of age. Western blots and histoblots
showed that the total amount of protein and the laminar expression pattern of
GABAB1 were similar in APP/PS1 mice and in age‐matched wild‐type mice. In contrast,
immunoelectron microscopic techniques showed that the subcellular localization
of GABAB1 subunit did not change significantly in APP/PS1 mice at 1 month of age,
was significantly reduced in the stratum lacunosum‐moleculare of CA1 pyramidal
cells at 6 months of age and significantly reduced at the membrane surface of
CA1 pyramidal cells at 12 months of age. This reduction of plasma membrane GABAB1
was paralleled by a significant increase of the subunit at the intracellular sites.
We further observed a decrease of membrane‐targeted GABAB receptors in axon terminals
contacting CA1 pyramidal cells. Our data demonstrate compartment‐ and age‐dependent
reduction of plasma membrane‐targeted GABAB receptors in the CA1 region of the
hippocampus, suggesting that this decrease might be enough to alter the GABAB‐mediated
synaptic transmission taking place in AD.

text: Genetic incompatibilities contribute to reproductive isolation between many
diverging populations, but it is still unclear to what extent they play a role
if divergence happens with gene flow. In contact zones between the "Crab" and
"Wave" ecotypes of the snail Littorina saxatilis, divergent selection forms strong
barriers to gene flow, while the role of post‐zygotic barriers due to selection
against hybrids remains unclear. High embryo abortion rates in this species could
indicate the presence of such barriers. Post‐zygotic barriers might include genetic
incompatibilities (e.g. Dobzhansky–Muller incompatibilities) but also maladaptation,
both expected to be most pronounced in contact zones. In addition, embryo abortion
might reflect physiological stress on females and embryos independent of any genetic
stress. We examined all embryos of >500 females sampled outside and inside contact
zones of three populations in Sweden. Females' clutch size ranged from 0 to 1,011
embryos (mean 130 ± 123), and abortion rates varied between 0% and 100% (mean
12%). We described female genotypes by using a hybrid index based on hundreds
of SNPs differentiated between ecotypes with which we characterized female genotypes.
We also calculated female SNP heterozygosity and inversion karyotype. Clutch size
did not vary with female hybrid index, and abortion rates were only weakly related
to hybrid index in two sites but not at all in a third site. No additional variation
in abortion rate was explained by female SNP heterozygosity, but increased female
inversion heterozygosity added slightly to increased abortion. Our results show
only weak and probably biologically insignificant post‐zygotic barriers contributing
to ecotype divergence, and the high and variable abortion rates were marginally,
if at all, explained by hybrid index of females.

text: Gastrulation entails specification and formation of three embryonic germ layers—ectoderm,
mesoderm and endoderm—thereby establishing the basis for the future body plan.
In zebrafish embryos, germ layer specification occurs during blastula and early
gastrula stages (Ho & Kimmel, 1993), a period when the main morphogenetic movements
underlying gastrulation are initiated. Hence, the signals driving progenitor cell
fate specification, such as Nodal ligands from the TGF-β family, also play key
roles in regulating germ layer progenitor cell segregation (Carmany-Rampey & Schier,
2001; David & Rosa, 2001; Feldman et al., 2000; Gritsman et al., 1999; Keller
et al., 2008). In this review, we summarize and discuss the main signaling pathways
involved in germ layer progenitor cell fate specification and segregation, specifically
focusing on recent advances in understanding the interplay between mesoderm and
endoderm specification and the internalization movements at the onset of zebrafish
gastrulation.

text: Previously, we reported that the allelic de-etiolated by zinc (dez) and trichome
birefringence (tbr) mutants exhibit photomorphogenic development in the dark,
which is enhanced by high Zn. TRICHOME BIREFRINGENCE-LIKE proteins had been implicated
in transferring acetyl groups to various hemicelluloses. Pectin O-acetylation
levels were lower in dark-grown dez seedlings than in the wild type. We observed
Zn-enhanced photomorphogenesis in the dark also in the reduced wall acetylation
2 (rwa2-3) mutant, which exhibits lowered O-acetylation levels of cell wall macromolecules
including pectins and xyloglucans, supporting a role for cell wall macromolecule
O-acetylation in the photomorphogenic phenotypes of rwa2-3 and dez. Application
of very short oligogalacturonides (vsOGs) restored skotomorphogenesis in dark-grown
dez and rwa2-3. Here we demonstrate that in dez, O-acetylation of non-pectin cell
wall components, notably of xyloglucan, is enhanced. Our results highlight the
complexity of cell wall homeostasis and indicate against an influence of xyloglucan
O-acetylation on light-dependent seedling development.

text: For complex Wigner-type matrices, i.e. Hermitian random matrices with independent,
not necessarily identically distributed entries above the diagonal, we show that
at any cusp singularity of the limiting eigenvalue distribution the local eigenvalue
statistics are universal and form a Pearcey process. Since the density of states
typically exhibits only square root or cubic root cusp singularities, our work
complements previous results on the bulk and edge universality and it thus completes
the resolution of the Wigner–Dyson–Mehta universality conjecture for the last
remaining universality type in the complex Hermitian class. Our analysis holds
not only for exact cusps, but approximate cusps as well, where an extended Pearcey
process emerges. As a main technical ingredient we prove an optimal local law
at the cusp for both symmetry classes. This result is also the key input in the
companion paper (Cipolloni et al. in Pure Appl Anal, 2018. arXiv:1811.04055) where
the cusp universality for real symmetric Wigner-type matrices is proven. The novel
cusp fluctuation mechanism is also essential for the recent results on the spectral
radius of non-Hermitian random matrices (Alt et al. in Spectral radius of random
matrices with independent entries, 2019. arXiv:1907.13631), and the non-Hermitian
edge universality (Cipolloni et al. in Edge universality for non-Hermitian random
matrices, 2019. arXiv:1908.00969).

text: "This thesis is based on three main topics: In the first part, we study convergence
of discrete gradient flow structures associated with regular finite-volume discretisations
of Fokker-Planck equations. We show evolutionary I convergence of the discrete
gradient flows to the L2-Wasserstein gradient flow corresponding to the solution
of a Fokker-Planck\r\nequation in arbitrary dimension d >= 1. Along the argument,
we prove Mosco- and I-convergence results for discrete energy functionals, which
are of independent interest for convergence of equivalent gradient flow structures
in Hilbert spaces.\r\nThe second part investigates L2-Wasserstein flows on metric
graph. The starting point is a Benamou-Brenier formula for the L2-Wasserstein
distance, which is proved via a regularisation scheme for solutions of the continuity
equation, adapted to the peculiar geometric structure of metric graphs. Based
on those results, we show that the L2-Wasserstein space over a metric graph admits
a gradient flow which may be identified as a solution of a Fokker-Planck equation.\r\nIn
the third part, we focus again on the discrete gradient flows, already encountered
in the first part. We propose a variational structure which extends the gradient
flow structure to Markov chains violating the detailed-balance conditions. Using
this structure, we characterise contraction estimates for the discrete heat flow
in terms of convexity of\r\ncorresponding path-dependent energy functionals. In
addition, we use this approach to derive several functional inequalities for said
functionals."

text: "This thesis concerns itself with the interactions of evolutionary and ecological
forces and the consequences on genetic diversity and the ultimate survival of
populations. It is important to understand what signals processes \r\nleave on
the genome and what we can infer from such data, which is usually abundant but
noisy. Furthermore, understanding how and when populations adapt or go extinct
is important for practical purposes, such as the genetic management of populations,
as well as for theoretical questions, since local adaptation can be the first
step toward speciation. \r\nIn Chapter 2, we introduce the method of maximum entropy
to approximate the demographic changes of a population in a simple setting, namely
the logistic growth model with immigration. We show that this method is not only
a powerful \r\ntool in physics but can be gainfully applied in an ecological framework.
We investigate how well it approximates the real \r\nbehavior of the system, and
find that is does so, even in unexpected situations. Finally, we illustrate how
it can model changing environments.\r\nIn Chapter 3, we analyze the co-evolution
of allele frequencies and population sizes in an infinite island model.\r\nWe
give conditions under which polygenic adaptation to a rare habitat is possible.
The model we use is based on the diffusion approximation, considers eco-evolutionary
feedback mechanisms (hard selection), and treats both \r\ndrift and environmental
fluctuations explicitly. We also look at limiting scenarios, for which we derive
analytical expressions. \r\nIn Chapter 4, we present a coalescent based simulation
tool to obtain patterns of diversity in a spatially explicit subdivided population,
in which the demographic history of each subpopulation can be specified. We compare
\r\nthe results to existing predictions, and explore the relative importance of
time and space under a variety of spatial arrangements and demographic histories,
such as expansion and extinction. \r\nIn the last chapter, we give a brief outlook
to further research. "

text: "We study the interacting homogeneous Bose gas in two spatial dimensions in
the thermodynamic limit at fixed density. We shall be concerned with some mathematical
aspects of this complicated problem in many-body quantum mechanics. More specifically,
we consider the dilute limit where the scattering length of the interaction potential,
which is a measure for the effective range of the potential, is small compared
to the average distance between the particles. We are interested in a setting
with positive (i.e., non-zero) temperature. After giving a survey of the relevant
literature in the field, we provide some facts and examples to set expectations
for the two-dimensional system. The crucial difference to the three-dimensional
system is that there is no Bose–Einstein condensate at positive temperature due
to the Hohenberg–Mermin–Wagner theorem. However, it turns out that an asymptotic
formula for the free energy holds similarly to the three-dimensional case.\r\nWe
motivate this formula by considering a toy model with δ interaction potential.
By restricting this model Hamiltonian to certain trial states with a quasi-condensate
we obtain an upper bound for the free energy that still has the quasi-condensate
fraction as a free parameter. When minimizing over the quasi-condensate fraction,
we obtain the Berezinskii–Kosterlitz–Thouless critical temperature for superfluidity,
which plays an important role in our rigorous contribution. The mathematically
rigorous result that we prove concerns the specific free energy in the dilute
limit. We give upper and lower bounds on the free energy in terms of the free
energy of the non-interacting system and a correction term coming from the interaction.
Both bounds match and thus we obtain the leading term of an asymptotic approximation
in the dilute limit, provided the thermal wavelength of the particles is of the
same order (or larger) than the average distance between the particles. The remarkable
feature of this result is its generality: the correction term depends on the interaction
potential only through its scattering length and it holds for all nonnegative
interaction potentials with finite scattering length that are measurable. In particular,
this allows to model an interaction of hard disks."

text: "Mrp (Multi resistance and pH adaptation) are broadly distributed secondary
active antiporters that catalyze the transport of monovalent ions such as sodium
and potassium outside of the cell coupled to the inward translocation of protons.
Mrp antiporters are unique in a way that they are composed of seven subunits (MrpABCDEFG)
encoded in a single operon, whereas other antiporters catalyzing the same reaction
are mostly encoded by a single gene. Mrp exchangers are crucial for intracellular
pH homeostasis and Na+ efflux, essential mechanisms for H+ uptake under alkaline
environments and for reduction of the intracellular concentration of toxic cations.
Mrp displays no homology to any other monovalent Na+(K+)/H+ antiporters but Mrp
subunits have primary sequence similarity to essential redox-driven proton pumps,
such as respiratory complex I and membrane-bound hydrogenases. This similarity
reinforces the hypothesis that these present day redox-driven proton pumps are
descended from the Mrp antiporter. The Mrp structure serves as a model to understand
the yet obscure coupling mechanism between ion or electron transfer and proton
translocation in this large group of proteins. In the thesis, I am presenting
the purification, biochemical analysis, cryo-EM analysis and molecular structure
of the Mrp complex from Anoxybacillus flavithermus solved by cryo-EM at 3.0 Å
resolution. Numerous conditions were screened to purify Mrp to high homogeneity
and to obtain an appropriate distribution of single particles on cryo-EM grids
covered with a continuous layer of ultrathin carbon. A preferred particle orientation
problem was solved by performing a tilted data collection. The activity assays
showed the specific pH-dependent\r\nprofile of secondary active antiporters. The
molecular structure shows that Mrp is a dimer of seven-subunit protomers with
50 trans-membrane helices each. The dimer interface is built by many short and
tilted transmembrane helices, probably causing a thinning of the bacterial membrane.
The surface charge distribution shows an extraordinary asymmetry within each monomer,
revealing presumable proton and sodium translocation pathways. The two largest\r\nand
homologous Mrp subunits MrpA and MrpD probably translocate one proton each into
the cell. The sodium ion is likely being translocated in the opposite direction
within the small subunits along a ladder of charged and conserved residues. Based
on the structure, we propose a mechanism were the antiport activity is accomplished
via electrostatic interactions between the charged cations and key charged residues.
The flexible key TM helices coordinate these\r\nelectrostatic interactions, while
the membrane thinning between the monomers enables the translocation of sodium
across the charged membrane. The entire family of redox-driven proton pumps is
likely to perform their mechanism in a likewise manner."

text: The plant hormone auxin plays indispensable roles in plant growth and development.
An essential level of regulation in auxin action is the directional auxin transport
within cells. The establishment of auxin gradient in plant tissue has been attributed
to local auxin biosynthesis and directional intercellular auxin transport, which
both are controlled by various environmental and developmental signals. It is
well established that asymmetric auxin distribution in cells is achieved by polarly
localized PIN-FORMED (PIN) auxin efflux transporters. Despite the initial insights
into cellular mechanisms of PIN polarization obtained from the last decades, the
molecular mechanism and specific regulators mediating PIN polarization remains
elusive. In this thesis, we aim to find novel players in PIN subcellular polarity
regulation during Arabidopsis development. We first characterize the physiological
effect of piperonylic acid (PA) on Arabidopsis hypocotyl gravitropic bending and
PIN polarization. Secondly, we reveal the importance of SCFTIR1/AFB auxin signaling
pathway in shoot gravitropism bending termination. In addition, we also explore
the role of myosin XI complex, and actin cytoskeleton in auxin feedback regulation
on PIN polarity. In Chapter 1, we give an overview of the current knowledge about
PIN-mediated auxin fluxes in various plant tropic responses. In Chapter 2, we
study the physiological effect of PA on shoot gravitropic bending. Our results
show that PA treatment inhibits auxin-mediated PIN3 repolarization by interfering
with PINOID and PIN3 phosphorylation status, ultimately leading to hyperbending
hypocotyls. In Chapter 3, we provide evidence to show that the SCFTIR1/AFB nuclear
auxin signaling pathway is crucial and required for auxin-mediated PIN3 repolarization
and shoot gravitropic bending termination. In Chapter 4, we perform a phosphoproteomics
approach and identify the motor protein Myosin XI and its binding protein, the
MadB2 family, as an essential regulator of PIN polarity for auxin-canalization
related developmental processes. In Chapter 5, we demonstrate the vital role of
actin cytoskeleton in auxin feedback on PIN polarity by regulating PIN subcellular
trafficking. Overall, the data presented in this PhD thesis brings novel insights
into the PIN polar localization regulation that resulted in the (re)establishment
of the polar auxin flow and gradient in response to environmental stimuli during
plant development.

text: Multiple resistance and pH adaptation (Mrp) antiporters are multi-subunit
Na+ (or K+)/H+ exchangers representing an ancestor of many essential redox-driven
proton pumps, such as respiratory complex I. The mechanism of coupling between
ion or electron transfer and proton translocation in this large protein family
is unknown. Here, we present the structure of the Mrp complex from Anoxybacillus
flavithermus solved by cryo-EM at 3.0 Å resolution. It is a dimer of seven-subunit
protomers with 50 trans-membrane helices each. Surface charge distribution within
each monomer is remarkably asymmetric, revealing probable proton and sodium translocation
pathways. On the basis of the structure we propose a mechanism where the coupling
between sodium and proton translocation is facilitated by a series of electrostatic
interactions between a cation and key charged residues. This mechanism is likely
to be applicable to the entire family of redox proton pumps, where electron transfer
to substrates replaces cation movements.

text: "In the thesis we focus on the interplay of the biophysics and evolution of
gene regulation. We start by addressing how the type of prokaryotic gene regulation
– activation and repression – affects spurious binding to DNA, also known as\r\ntranscriptional
crosstalk. We propose that regulatory interference caused by excess regulatory
proteins in the dense cellular medium – global crosstalk – could be a factor in
determining which type of gene regulatory network is evolutionarily preferred.
Next,we use a normative approach in eukaryotic gene regulation to describe minimal\r\nnon-equilibrium
enhancer models that optimize so-called regulatory phenotypes. We find a class
of models that differ from standard thermodynamic equilibrium models by a single
parameter that notably increases the regulatory performance. Next chapter addresses
the question of genotype-phenotype-fitness maps of higher dimensional phenotypes.
We show that our biophysically realistic approach allows us to understand how
the mechanisms of promoter function constrain genotypephenotype maps, and how
they affect the evolutionary trajectories of promoters.\r\nIn the last chapter
we ask whether the intrinsic instability of gene duplication and amplification
provides a generic alternative to canonical gene regulation. Using mathematical
modeling, we show that amplifications can tune gene expression in many environments,
including those where transcription factor-based schemes are\r\nhard to evolve
or maintain. "

text: 'In prokaryotes, thermodynamic models of gene regulation provide a highly
quantitative mapping from promoter sequences to gene expression levels that is
compatible with in vivo and in vitro bio-physical measurements. Such concordance
has not been achieved for models of enhancer function in eukaryotes. In equilibrium
models, it is difficult to reconcile the reported short transcription factor (TF)
residence times on the DNA with the high specificity of regulation. In non-equilibrium
models, progress is difficult due to an explosion in the number of parameters.
Here, we navigate this complexity by looking for minimal non-equilibrium enhancer
models that yield desired regulatory phenotypes: low TF residence time, high specificity
and tunable cooperativity. We find that a single extra parameter, interpretable
as the “linking rate” by which bound TFs interact with Mediator components, enables
our models to escape equilibrium bounds and access optimal regulatory phenotypes,
while remaining consistent with the reported phenomenology and simple enough to
be inferred from upcoming experiments. We further find that high specificity in
non-equilibrium models is in a tradeoff with gene expression noise, predicting
bursty dynamics — an experimentally-observed hallmark of eukaryotic transcription.
By drastically reducing the vast parameter space to a much smaller subspace that
optimally realizes biological function prior to inference from data, our normative
approach holds promise for mathematical models in systems biology.'

text: "Many methods for the reconstruction of shapes from sets of points produce
ordered simplicial complexes, which are collections of vertices, edges, triangles,
and their higher-dimensional analogues, called simplices, in which every simplex
gets assigned a real value measuring its size. This thesis studies ordered simplicial
complexes, with a focus on their topology, which reflects the connectedness of
the represented shapes and the presence of holes. We are interested both in understanding
better the structure of these complexes, as well as in developing algorithms for
applications.\r\n\r\nFor the Delaunay triangulation, the most popular measure
for a simplex is the radius of the smallest empty circumsphere. Based on it, we
revisit Alpha and Wrap complexes and experimentally determine their probabilistic
properties for random data. Also, we prove the existence of tri-partitions, propose
algorithms to open and close holes, and extend the concepts from Euclidean to
Bregman geometries."

text: "A search problem lies in the complexity class FNP if a solution to the given
instance of the problem can be verified efficiently. The complexity class TFNP
consists of all search problems in FNP that are total in the sense that a solution
is guaranteed to exist. TFNP contains a host of interesting problems from fields
such as algorithmic game theory, computational topology, number theory and combinatorics.
Since TFNP is a semantic class, it is unlikely to have a complete problem. Instead,
one studies its syntactic subclasses which are defined based on the combinatorial
principle used to argue totality. Of particular interest is the subclass PPAD,
which contains important problems\r\nlike computing Nash equilibrium for bimatrix
games and computational counterparts of several fixed-point theorems as complete.
In the thesis, we undertake the study of averagecase hardness of TFNP, and in
particular its subclass PPAD.\r\nAlmost nothing was known about average-case hardness
of PPAD before a series of recent results showed how to achieve it using a cryptographic
primitive called program obfuscation.\r\nHowever, it is currently not known how
to construct program obfuscation from standard cryptographic assumptions. Therefore,
it is desirable to relax the assumption under which average-case hardness of PPAD
can be shown. In the thesis we take a step in this direction. First, we show that
assuming the (average-case) hardness of a numbertheoretic\r\nproblem related to
factoring of integers, which we call Iterated-Squaring, PPAD is hard-on-average
in the random-oracle model. Then we strengthen this result to show that the average-case
hardness of PPAD reduces to the (adaptive) soundness of the Fiat-Shamir Transform,
a well-known technique used to compile a public-coin interactive protocol into
a non-interactive one. As a corollary, we obtain average-case hardness for PPAD
in the random-oracle model assuming the worst-case hardness of #SAT. Moreover,
the above results can all be strengthened to obtain average-case hardness for
the class CLS ⊆ PPAD.\r\nOur main technical contribution is constructing incrementally-verifiable
procedures for computing Iterated-Squaring and #SAT. By incrementally-verifiable,
we mean that every intermediate state of the computation includes a proof of its
correctness, and the proof can be updated and verified in polynomial time. Previous
constructions of such procedures relied on strong, non-standard assumptions. Instead,
we introduce a technique called recursive proof-merging to obtain the same from
weaker assumptions. "

text: 'State-of-the-art detection systems are generally evaluated on their ability
to exhaustively retrieve objects densely distributed in the image, across a wide
variety of appearances and semantic categories. Orthogonal to this, many real-life
object detection applications, for example in remote sensing, instead require
dealing with large images that contain only a few small objects of a single class,
scattered heterogeneously across the space. In addition, they are often subject
to strict computational constraints, such as limited battery capacity and computing
power.To tackle these more practical scenarios, we propose a novel flexible detection
scheme that efficiently adapts to variable object sizes and densities: We rely
on a sequence of detection stages, each of which has the ability to predict groups
of objects as well as individuals. Similar to a detection cascade, this multi-stage
architecture spares computational effort by discarding large irrelevant regions
of the image early during the detection process. The ability to group objects
provides further computational and memory savings, as it allows working with lower
image resolutions in early stages, where groups are more easily detected than
individuals, as they are more salient. We report experimental results on two aerial
image datasets, and show that the proposed method is as accurate yet computationally
more efficient than standard single-shot detectors, consistently across three
different backbone architectures.'

text: 'Fine-tuning is a popular way of exploiting knowledge contained in a pre-trained
convolutional network for a new visual recognition task. However, the orthogonal
setting of transferring knowledge from a pretrained network to a visually different
yet semantically close source is rarely considered: This commonly happens with
real-life data, which is not necessarily as clean as the training source (noise,
geometric transformations, different modalities, etc.).To tackle such scenarios,
we introduce a new, generalized form of fine-tuning, called flex-tuning, in which
any individual unit (e.g. layer) of a network can be tuned, and the most promising
one is chosen automatically. In order to make the method appealing for practical
use, we propose two lightweight and faster selection procedures that prove to
be good approximations in practice. We study these selection criteria empirically
across a variety of domain shifts and data scarcity scenarios, and show that fine-tuning
individual units, despite its simplicity, yields very good results as an adaptation
technique. As it turns out, in contrast to common practice, rather than the last
fully-connected unit it is best to tune an intermediate or early one in many domain-
shift scenarios, which is accurately detected by flex-tuning.'

text: 'Multiple-environment Markov decision processes (MEMDPs) are MDPs equipped
with not one, but multiple probabilistic transition functions, which represent
the various possible unknown environments. While the previous research on MEMDPs
focused on theoretical properties for long-run average payoff, we study them with
discounted-sum payoff and focus on their practical advantages and applications.
MEMDPs can be viewed as a special case of Partially observable and Mixed observability
MDPs: the state of the system is perfectly observable, but not the environment.
We show that the specific structure of MEMDPs allows for more efficient algorithmic
analysis, in particular for faster belief updates. We demonstrate the applicability
of MEMDPs in several domains. In particular, we formalize the sequential decision-making
approach to contextual recommendation systems as MEMDPs and substantially improve
over the previous MDP approach.'

text: Image translation refers to the task of mapping images from a visual domain
to another. Given two unpaired collections of images, we aim to learn a mapping
between the corpus-level style of each collection, while preserving semantic content
shared across the two domains. We introduce xgan, a dual adversarial auto-encoder,
which captures a shared representation of the common domain semantic content in
an unsupervised way, while jointly learning the domain-to-domain image translations
in both directions. We exploit ideas from the domain adaptation literature and
define a semantic consistency loss which encourages the learned embedding to preserve
semantics shared across domains. We report promising qualitative results for the
task of face-to-cartoon translation. The cartoon dataset we collected for this
purpose, “CartoonSet”, is also publicly available as a new benchmark for semantic
style transfer at https://google.github.io/cartoonset/index.html.

text: "This thesis considers two examples of reconfiguration problems: flipping
edges in edge-labelled triangulations of planar point sets and swapping labelled
tokens placed on vertices of a graph. In both cases the studied structures – all
the triangulations of a given point set or all token placements on a given graph
– can be thought of as vertices of the so-called reconfiguration graph, in which
two vertices are adjacent if the corresponding structures differ by a single elementary
operation – by a flip of a diagonal in a triangulation or by a swap of tokens
on adjacent vertices, respectively. We study the reconfiguration of one instance
of a structure into another via (shortest) paths in the reconfiguration graph.\r\n\r\nFor
triangulations of point sets in which each edge has a unique label and a flip
transfers the label from the removed edge to the new edge, we prove a polynomial-time
testable condition, called the Orbit Theorem, that characterizes when two triangulations
of the same point set lie in the same connected component of the reconfiguration
graph. The condition was first conjectured by Bose, Lubiw, Pathak and Verdonschot.
We additionally provide a polynomial time algorithm that computes a reconfiguring
flip sequence, if it exists. Our proof of the Orbit Theorem uses topological properties
of a certain high-dimensional cell complex that has the usual reconfiguration
graph as its 1-skeleton.\r\n\r\nIn the context of token swapping on a tree graph,
we make partial progress on the problem of finding shortest reconfiguration sequences.
We disprove the so-called Happy Leaf Conjecture and demonstrate the importance
of swapping tokens that are already placed at the correct vertices. We also prove
that a generalization of the problem to weighted coloured token swapping is NP-hard
on trees but solvable in polynomial time on paths and stars."

text: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. By analogy with the bipolaron, we introduce the biangulon quasiparticle
describing two rotating molecules that align with respect to each other due to
the effective attractive interaction mediated by the excitations of the bath.
We study this system in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, we introduce a diagonalization scheme that allows us to describe
the transition from two separated angulons to a biangulon as a function of the
distance between the two molecules.

text: "One of the most striking hallmarks of the eukaryotic cell is the presence
of intracellular vesicles and organelles. Each of these membrane-enclosed compartments
has a distinct composition of lipids and proteins, which is essential for accurate
membrane traffic and homeostasis. Interestingly, their biochemical identities
are achieved with the help\r\nof small GTPases of the Rab family, which cycle
between GDP- and GTP-bound forms on the selected membrane surface. While this
activity switch is well understood for an individual protein, how Rab GTPases
collectively transition between states to generate decisive signal propagation
in space and time is unclear. In my PhD thesis, I present\r\nin vitro reconstitution
experiments with theoretical modeling to systematically study a minimal Rab5 activation
network from bottom-up. We find that positive feedback based on known molecular
interactions gives rise to bistable GTPase activity switching on system’s scale.
Furthermore, we determine that collective transition near the critical\r\npoint
is intrinsically stochastic and provide evidence that the inactive Rab5 abundance
on the membrane can shape the network response. Finally, we demonstrate that collective
switching can spread on the lipid bilayer as a traveling activation wave, representing
a possible emergent activity pattern in endosomal maturation. Together, our\r\nfindings
reveal new insights into the self-organization properties of signaling networks
away from chemical equilibrium. Our work highlights the importance of systematic
characterization of biochemical systems in well-defined physiological conditions.
This way, we were able to answer long-standing open questions in the field and
close the gap between regulatory processes on a molecular scale and emergent responses
on system’s level."

text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
family, which are activated at defined times and locations in a switch-like manner.
While this switch is well understood for an individual protein, how regulatory
networks produce intracellular activity patterns is currently not known. Here,
we combine in vitro reconstitution experiments with computational modeling to
study a minimal Rab5 activation network. We find that the molecular interactions
in this system give rise to a positive feedback and bistable collective switching
of Rab5. Furthermore, we find that switching near the critical point is intrinsically
stochastic and provide evidence that controlling the inactive population of Rab5
on the membrane can shape the network response. Notably, we demonstrate that collective
switching can spread on the membrane surface as a traveling wave of Rab5 activation.
Together, our findings reveal how biochemical signaling networks control vesicle
trafficking pathways and how their nonequilibrium properties define the spatiotemporal
organization of the cell.

text: "Algorithms in computational 3-manifold topology typically take a triangulation
as an input and return topological information about the underlying 3-manifold.
However, extracting the desired information from a triangulation (e.g., evaluating
an invariant) is often computationally very expensive. In recent years this complexity
barrier has been successfully tackled in some cases by importing ideas from the
theory of parameterized algorithms into the realm of 3-manifolds. Various computationally
hard problems were shown to be efficiently solvable for input triangulations that
are sufficiently “tree-like.”\r\nIn this thesis we focus on the key combinatorial
parameter in the above context: we consider the treewidth of a compact, orientable
3-manifold, i.e., the smallest treewidth of the dual graph of any triangulation
thereof. By building on the work of Scharlemann–Thompson and Scharlemann–Schultens–Saito
on generalized Heegaard splittings, and on the work of Jaco–Rubinstein on layered
triangulations, we establish quantitative relations between the treewidth and
classical topological invariants of a 3-manifold. In particular, among other results,
we show that the treewidth of a closed, orientable, irreducible, non-Haken 3-manifold
is always within a constant factor of its Heegaard genus."
