text: A tight frame is the orthogonal projection of some orthonormal basis of Rn
onto Rk. We show that a set of vectors is a tight frame if and only if the set
of all cross products of these vectors is a tight frame. We reformulate a range
of problems on the volume of projections (or sections) of regular polytopes in
terms of tight frames and write a first-order necessary condition for local extrema
of these problems. As applications, we prove new results for the problem of maximization
of the volume of zonotopes.

text: Polar subcellular localization of the PIN exporters of the phytohormone auxin
is a key determinant of directional, intercellular auxin transport and thus a
central topic of both plant cell and developmental biology. Arabidopsis mutants
lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown
molecular function display PIN polarity defects and phenocopy pin mutants, but
mechanistic insights into how these factors convey PIN polarity are missing. Here,
by combining protein biochemistry with quantitative live-cell imaging, we demonstrate
that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma
membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert
with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based
escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has
self-reinforcing properties thanks to positive feedback between AGC kinase-mediated
PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism
by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant
development.

text: Plants are able to orient their growth according to gravity, which ultimately
controls both shoot and root architecture.1 Gravitropism is a dynamic process
whereby gravistimulation induces the asymmetric distribution of the plant hormone
auxin, leading to asymmetric growth, organ bending, and subsequent reset of auxin
distribution back to the original pre-gravistimulation situation.1, 2, 3 Differential
auxin accumulation during the gravitropic response depends on the activity of
polarly localized PIN-FORMED (PIN) auxin-efflux carriers.1, 2, 3, 4 In particular,
the timing of this dynamic response is regulated by PIN2,5,6 but the underlying
molecular mechanisms are poorly understood. Here, we show that MEMBRANE ASSOCIATED
KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response.
We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by
acting as a negative regulator of the cell-surface signaling mediated by the receptor-like
kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that
the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself,
which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our
findings suggest that the timing of the root gravitropic response is orchestrated
by the reversible inhibition of the TMK1 signaling pathway at the cell surface.

text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
Current understanding states that the partition between surface adsorbed and dissolved
lithium superoxide governs whether Li2O2 grows as a conformal surface film or
larger particles, leading to low or high capacities, respectively. However, better
understanding governing factors for Li2O2 packing density and capacity requires
structural sensitive in situ metrologies. Here, we establish in situ small- and
wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
phase evolution with atomic to submicrometer resolution during cycling a custom-built
in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
rich quantitative structural information from complex multiphase systems. Surprisingly,
we find that features are absent that would point at a Li2O2 surface film formed
via two consecutive electron transfers, even in poorly solvating electrolytes
thought to be prototypical for surface growth. All scattering data can be modeled
by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
particles, but there is no transition to an electronically passivating, conformal
Li2O2 coating. Hence, mass transport of reactive species rather than electronic
transport through a Li2O2 film limits the discharge capacity. Provided that species
mobilities and carbon surface areas are high, this allows for high discharge capacities
even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
ought to be reconsidered.

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). Upon increasing the salt
concentration towards superconcentration the onset of the oxygen evolution reaction
(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: Dendritic cells (DCs) are crucial for the priming of naive T cells and the
initiation of adaptive immunity. Priming is initiated at a heterologous cell–cell
contact, the immunological synapse (IS). While it is established that F-actin
dynamics regulates signaling at the T cell side of the contact, little is known
about the cytoskeletal contribution on the DC side. Here, we show that the DC
actin cytoskeleton is decisive for the formation of a multifocal synaptic structure,
which correlates with T cell priming efficiency. DC actin at the IS appears in
transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence
of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase
in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of
activated and proliferating T cells, demonstrating an important role for DC actin
in the regulation of immune synapse functionality.

text: The sensory and cognitive abilities of the mammalian neocortex are underpinned
by intricate columnar and laminar circuits formed from an array of diverse neuronal
populations. One approach to determining how interactions between these circuit
components give rise to complex behavior is to investigate the rules by which
cortical circuits are formed and acquire functionality during development. This
review summarizes recent research on the development of the neocortex, from genetic
determination in neural stem cells through to the dynamic role that specific neuronal
populations play in the earliest circuits of neocortex, and how they contribute
to emergent function and cognition. While many of these endeavors take advantage
of model systems, consideration will also be given to advances in our understanding
of activity in nascent human circuits. Such cross-species perspective is imperative
when investigating the mechanisms underlying the dysfunction of early neocortical
circuits in neurodevelopmental disorders, so that one can identify targets amenable
to therapeutic intervention.

text: "We study the problem of recovering an unknown signal \U0001D465\U0001D465
given measurements obtained from a generalized linear model with a Gaussian sensing
matrix. Two popular solutions are based on a linear estimator \U0001D465\U0001D465^L
and a spectral estimator \U0001D465\U0001D465^s. The former is a data-dependent
linear combination of the columns of the measurement matrix, and its analysis
is quite simple. The latter is the principal eigenvector of a data-dependent matrix,
and a recent line of work has studied its performance. In this paper, we show
how to optimally combine \U0001D465\U0001D465^L and \U0001D465\U0001D465^s. At
the heart of our analysis is the exact characterization of the empirical joint
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s)
in the high-dimensional limit. This allows us to compute the Bayes-optimal combination
of \U0001D465\U0001D465^L and \U0001D465\U0001D465^s, given the limiting distribution
of the signal \U0001D465\U0001D465. When the distribution of the signal is Gaussian,
then the Bayes-optimal combination has the form \U0001D703\U0001D465\U0001D465^L+\U0001D465\U0001D465^s
and we derive the optimal combination coefficient. In order to establish the limiting
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s),
we design and analyze an approximate message passing algorithm whose iterates
give \U0001D465\U0001D465^L and approach \U0001D465\U0001D465^s. Numerical simulations
demonstrate the improvement of the proposed combination with respect to the two
methods considered separately."

text: In this paper, we present two new inertial projection-type methods for solving
multivalued variational inequality problems in finite-dimensional spaces. We establish
the convergence of the sequence generated by these methods when the multivalued
mapping associated with the problem is only required to be locally bounded without
any monotonicity assumption. Furthermore, the inertial techniques that we employ
in this paper are quite different from the ones used in most papers. Moreover,
based on the weaker assumptions on the inertial factor in our methods, we derive
several special cases of our methods. Finally, we present some experimental results
to illustrate the profits that we gain by introducing the inertial extrapolation
steps.

text: 'We study the probabilistic convergence between the mapper graph and the Reeb
graph of a topological space X equipped with a continuous function f:X→R. We first
give a categorification of the mapper graph and the Reeb graph by interpreting
them in terms of cosheaves and stratified covers of the real line R. We then introduce
a variant of the classic mapper graph of Singh et al. (in: Eurographics symposium
on point-based graphics, 2007), referred to as the enhanced mapper graph, and
demonstrate that such a construction approximates the Reeb graph of (X,f) when
it is applied to points randomly sampled from a probability density function concentrated
on (X,f). Our techniques are based on the interleaving distance of constructible
cosheaves and topological estimation via kernel density estimates. Following Munch
and Wang (In: 32nd international symposium on computational geometry, volume 51
of Leibniz international proceedings in informatics (LIPIcs), Dagstuhl, Germany,
pp 53:1–53:16, 2016), we first show that the mapper graph of (X,f), a constructible
R-space (with a fixed open cover), approximates the Reeb graph of the same space.
We then construct an isomorphism between the mapper of (X,f) to the mapper of
a super-level set of a probability density function concentrated on (X,f). Finally,
building on the approach of Bobrowski et al. (Bernoulli 23(1):288–328, 2017b),
we show that, with high probability, we can recover the mapper of the super-level
set given a sufficiently large sample. Our work is the first to consider the mapper
construction using the theory of cosheaves in a probabilistic setting. It is part
of an ongoing effort to combine sheaf theory, probability, and statistics, to
support topological data analysis with random data.'

text: 'This paper analyses the conditions for local adaptation in a metapopulation
with infinitely many islands under a model of hard selection, where population
size depends on local fitness. Each island belongs to one of two distinct ecological
niches or habitats. Fitness is influenced by an additive trait which is under
habitat‐dependent directional selection. Our analysis is based on the diffusion
approximation and accounts for both genetic drift and demographic stochasticity.
By neglecting linkage disequilibria, it yields the joint distribution of allele
frequencies and population size on each island. We find that under hard selection,
the conditions for local adaptation in a rare habitat are more restrictive for
more polygenic traits: even moderate migration load per locus at very many loci
is sufficient for population sizes to decline. This further reduces the efficacy
of selection at individual loci due to increased drift and because smaller populations
are more prone to swamping due to migration, causing a positive feedback between
increasing maladaptation and declining population sizes. Our analysis also highlights
the importance of demographic stochasticity, which exacerbates the decline in
numbers of maladapted populations, leading to population collapse in the rare
habitat at significantly lower migration than predicted by deterministic arguments.'

text: If there are no constraints on the process of speciation, then the number
of species might be expected to match the number of available niches and this
number might be indefinitely large. One possible constraint is the opportunity
for allopatric divergence. In 1981, Felsenstein used a simple and elegant model
to ask if there might also be genetic constraints. He showed that progress towards
speciation could be described by the build‐up of linkage disequilibrium among
divergently selected loci and between these loci and those contributing to other
forms of reproductive isolation. Therefore, speciation is opposed by recombination,
because it tends to break down linkage disequilibria. Felsenstein then introduced
a crucial distinction between “two‐allele” models, which are subject to this effect,
and “one‐allele” models, which are free from the recombination constraint. These
fundamentally important insights have been the foundation for both empirical and
theoretical studies of speciation ever since.

text: Combining hybrid zone analysis with genomic data is a promising approach to
understanding the genomic basis of adaptive divergence. It allows for the identification
of genomic regions underlying barriers to gene flow. It also provides insights
into spatial patterns of allele frequency change, informing about the interplay
between environmental factors, dispersal and selection. However, when only a single
hybrid zone is analysed, it is difficult to separate patterns generated by selection
from those resulting from chance. Therefore, it is beneficial to look for repeatable
patterns across replicate hybrid zones in the same system. We applied this approach
to the marine snail Littorina saxatilis, which contains two ecotypes, adapted
to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous
hybrid zones between ecotypes offered the opportunity to test for the repeatability
of genomic architectures and spatial patterns of divergence. We sampled and phenotyped
snails from seven replicate hybrid zones on the Swedish west coast and genotyped
them for thousands of single nucleotide polymorphisms. Shell shape and size showed
parallel clines across all zones. Many genomic regions showing steep clines and/or
high differentiation were shared among hybrid zones, consistent with a common
evolutionary history and extensive gene flow between zones, and supporting the
importance of these regions for divergence. In particular, we found that several
large putative inversions contribute to divergence in all locations. Additionally,
we found evidence for consistent displacement of clines from the boulder–rock
transition. Our results demonstrate patterns of spatial variation that would not
be accessible without continuous spatial sampling, a large genomic data set and
replicate hybrid zones.

text: "• The phenylpropanoid pathway serves a central role in plant metabolism,
providing numerous compounds involved in diverse physiological processes. Most
carbon entering the pathway is incorporated into lignin. Although several phenylpropanoid
pathway mutants show seedling growth arrest, the role for lignin in seedling growth
and development is unexplored.\r\n• We use complementary pharmacological and genetic
approaches to block CINNAMATE‐4‐HYDROXYLASE (C4H) functionality in Arabidopsis
seedlings and a set of molecular and biochemical techniques to investigate the
underlying phenotypes.\r\n• Blocking C4H resulted in reduced lateral rooting and
increased adventitious rooting apically in the hypocotyl. These phenotypes coincided
with an inhibition in auxin transport. The upstream accumulation in cis‐cinnamic
acid was found to likely cause polar auxin transport inhibition. Conversely, a
downstream depletion in lignin perturbed phloem‐mediated auxin transport. Restoring
lignin deposition effectively reestablished phloem transport and, accordingly,
auxin homeostasis.\r\n• Our results show that the accumulation of bioactive intermediates
and depletion in lignin jointly cause the aberrant phenotypes upon blocking C4H,
and demonstrate that proper deposition of lignin is essential for the establishment
of auxin distribution in seedlings. Our data position the phenylpropanoid pathway
and lignin in a new physiological framework, consolidating their importance in
plant growth and development."

text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: Hartree–Fock theory has been justified as a mean-field approximation for fermionic
systems. However, it suffers from some defects in predicting physical properties,
making necessary a theory of quantum correlations. Recently, bosonization of many-body
correlations has been rigorously justified as an upper bound on the correlation
energy at high density with weak interactions. We review the bosonic approximation,
deriving an effective Hamiltonian. We then show that for systems with Coulomb
interaction this effective theory predicts collective excitations (plasmons) in
accordance with the random phase approximation of Bohm and Pines, and with experimental
observation.

text: "In this thesis we study persistence of multi-covers of Euclidean balls and
the geometric structures underlying their computation, in particular Delaunay
mosaics and Voronoi tessellations. The k-fold cover for some discrete input point
set consists of the space where at least k balls of radius r around the input
points overlap. Persistence is a notion that captures, in some sense, the topology
of the shape underlying the input. While persistence is usually computed for the
union of balls, the k-fold cover is of interest as it captures local density,\r\nand
thus might approximate the shape of the input better if the input data is noisy.
To compute persistence of these k-fold covers, we need a discretization that is
provided by higher-order Delaunay mosaics. We present and implement a simple and
efficient algorithm for the computation of higher-order Delaunay mosaics, and
use it to give experimental results for their combinatorial properties. The algorithm
makes use of a new geometric structure, the rhomboid tiling. It contains the higher-order
Delaunay mosaics as slices, and by introducing a filtration\r\nfunction on the
tiling, we also obtain higher-order α-shapes as slices. These allow us to compute
persistence of the multi-covers for varying radius r; the computation for varying
k is less straight-foward and involves the rhomboid tiling directly. We apply
our algorithms to experimental sphere packings to shed light on their structural
properties. Finally, inspired by periodic structures in packings and materials,
we propose and implement an algorithm for periodic Delaunay triangulations to
be integrated into the Computational Geometry Algorithms Library (CGAL), and discuss
the implications on persistence for periodic data sets."

text: "In the first part of the thesis we consider Hermitian random matrices. Firstly,
we consider sample covariance matrices XX∗ with X having independent identically
distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences
of linear statistics of XX∗ and its minor after removing the first column of X.
Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics
near cusp singularities of the limiting density of states are universal and that
they form a Pearcey process. Since the limiting eigenvalue distribution admits
only square root (edge) and cubic root (cusp) singularities, this concludes the
third and last remaining case of the Wigner-Dyson-Mehta universality conjecture.
The main technical ingredients are an optimal local law at the cusp, and the proof
of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp
regime.\r\nIn the second part we consider non-Hermitian matrices X with centred
i.i.d. entries. We normalise the entries of X to have variance N −1. It is well
known that the empirical eigenvalue density converges to the uniform distribution
on the unit disk (circular law). In the first project, we prove universality of
the local eigenvalue statistics close to the edge of the spectrum. This is the
non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically
we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck
flow for very long time\r\n(up to t = +∞). In the second project, we consider
linear statistics of eigenvalues for macroscopic test functions f in the Sobolev
space H2+ϵ and prove their convergence to the projection of the Gaussian Free
Field on the unit disk. We prove this result for non-Hermitian matrices with real
or complex entries. The main technical ingredients are: (i) local law for products
of two resolvents at different spectral parameters, (ii) analysis of correlated
Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically
rigorous application of supersymmetric techniques (SUSY ) to give a lower tail
estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we
use superbosonisation formula to give an integral representation of the resolvent
of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex
and real case, respectively. The rigorous analysis of these integrals is quite
challenging since simple saddle point analysis cannot be applied (the main contribution
comes from a non-trivial manifold). Our result\r\nimproves classical smoothing
inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality
for i.i.d. non-Hermitian matrices."

text: 'We study the inductive bias of two-layer ReLU networks trained by gradient
flow. We identify a class of easy-to-learn (`orthogonally separable'') datasets,
and characterise the solution that ReLU networks trained on such datasets converge
to. Irrespective of network width, the solution turns out to be a combination
of two max-margin classifiers: one corresponding to the positive data subset and
one corresponding to the negative data subset. The proof is based on the recently
introduced concept of extremal sectors, for which we prove a number of properties
in the context of orthogonal separability. In particular, we prove stationarity
of activation patterns from some time onwards, which enables a reduction of the
ReLU network to an ensemble of linear subnetworks.'

text: We investigate the Fröhlich polaron model on a three-dimensional torus, and
give a proof of the second-order quantum corrections to its ground-state energy
in the strong-coupling limit. Compared to previous work in the confined case,
the translational symmetry (and its breaking in the Pekar approximation) makes
the analysis substantially more challenging.

text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
of concurrent programs. As scheduling non-determinism creates exponentially large
spaces of thread interleavings, SMC attempts to partition this space into equivalence
classes and explore only a few representatives from each class. The efficiency
of this approach depends on two factors: (a) the coarseness of the partitioning,
and (b) the time to generate representatives in each class. For this reason, the
search for coarse partitionings that are efficiently explorable is an active research
challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a
novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
deemed equivalent if they agree on the value obtained in each read event, and
read events induce consistent causal orderings between them. The RVF partitioning
is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
partitionings. Our experimental evaluation reveals that RVF is quite often a very
effective equivalence, as the underlying partitioning is exponentially coarser
than other approaches. Moreover, RVF-SMC generates representatives very efficiently,
as the reduction in the partitioning is often met with significant speed-ups in
the model checking task.'

text: The present thesis is concerned with the derivation of weak-strong uniqueness
principles for curvature driven interface evolution problems not satisfying a
comparison principle. The specific examples being treated are two-phase Navier-Stokes
flow with surface tension, modeling the evolution of two incompressible, viscous
and immiscible fluids separated by a sharp interface, and multiphase mean curvature
flow, which serves as an idealized model for the motion of grain boundaries in
an annealing polycrystalline material. Our main results - obtained in joint works
with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation
of geometric singularities due to topology changes, the weak solution concept
of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with
surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial
Differential Equations 55, 2016) to multiphase mean curvature flow (for networks
in R^2 or double bubbles in R^3) represents the unique solution to these interface
evolution problems within the class of classical solutions, respectively. To the
best of the author's knowledge, for interface evolution problems not admitting
a geometric comparison principle the derivation of a weak-strong uniqueness principle
represented an open problem, so that the works contained in the present thesis
constitute the first positive results in this direction. The key ingredient of
our approach consists of the introduction of a novel concept of relative entropies
for a class of curvature driven interface evolution problems, for which the associated
energy contains an interfacial contribution being proportional to the surface
area of the evolving (network of) interface(s). The interfacial part of the relative
entropy gives sufficient control on the interface error between a weak and a classical
solution, and its time evolution can be computed, at least in principle, for any
energy dissipating weak solution concept. A resulting stability estimate for the
relative entropy essentially entails the above mentioned weak-strong uniqueness
principles. The present thesis contains a detailed introduction to our relative
entropy approach, which in particular highlights potential applications to other
problems in curvature driven interface evolution not treated in this thesis.

text: "In this work we solve the algorithmic problem of consistency verification
for the TSO and PSO memory models given a reads-from map, denoted VTSO-rf and
VPSO-rf, respectively. For an execution of n events over k threads and d variables,
we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k·
d) for PSO. Moreover, based on our solution to these problems, we develop an SMC
algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal,
in the sense that it is guaranteed to explore each class of the RF partitioning
exactly once, and spends polynomial time per class when k is bounded. Finally,
we implement all our algorithms in the SMC tool Nidhugg, and perform a large number
of experiments over benchmarks from existing literature. Our experimental results
show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability
improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning
is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO,
which yields a significant speedup in the model checking task.\r\n\r\n"

text: We derive a weak-strong uniqueness principle for BV solutions to multiphase
mean curvature flow of triple line clusters in three dimensions. Our proof is
based on the explicit construction of a gradient-flow calibration in the sense
of the recent work of Fischer et al. [arXiv:2003.05478] for any such cluster.
This extends the two-dimensional construction to the three-dimensional case of
surfaces meeting along triple junctions.

text: There are two elementary superconducting qubit types that derive directly
from the quantum harmonic oscillator. In one, the inductor is replaced by a nonlinear
Josephson junction to realize the widely used charge qubits with a compact phase
variable and a discrete charge wave function. In the other, the junction is added
in parallel, which gives rise to an extended phase variable, continuous wave functions,
and a rich energy-level structure due to the loop topology. While the corresponding
rf superconducting quantum interference device Hamiltonian was introduced as a
quadratic quasi-one-dimensional potential approximation to describe the fluxonium
qubit implemented with long Josephson-junction arrays, in this work we implement
it directly using a linear superinductor formed by a single uninterrupted aluminum
wire. We present a large variety of qubits, all stemming from the same circuit
but with drastically different characteristic energy scales. This includes flux
and fluxonium qubits but also the recently introduced quasicharge qubit with strongly
enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.
The use of a geometric inductor results in high reproducibility of the inductive
energy as guaranteed by top-down lithography—a key ingredient for intrinsically
protected superconducting qubits.

text: "This PhD thesis is primarily focused on the study of discrete transport problems,
introduced for the first time in the seminal works of Maas [Maa11] and Mielke
[Mie11] on finite state Markov chains and reaction-diffusion equations, respectively.
More in detail, my research focuses on the study of transport costs on graphs,
in particular the convergence and the stability of such problems in the discrete-to-continuum
limit. This thesis also includes some results concerning\r\nnon-commutative optimal
transport. The first chapter of this thesis consists of a general introduction
to the optimal transport problems, both in the discrete, the continuous, and the
non-commutative setting. Chapters 2 and 3 present the content of two works, obtained
in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have
been able to show the convergence of discrete transport costs on periodic graphs
to suitable continuous ones, which can be described by means of a homogenisation
result. We first focus on the particular case of quadratic costs on the real line
and then extending the result to more general costs in arbitrary dimension. Our
results are the first complete characterisation of limits of transport costs on
periodic graphs in arbitrary dimension which do not rely on any additional symmetry.
In Chapter 4 we turn our attention to one of the intriguing connection between
evolution equations and optimal transport, represented by the theory of gradient
flows. We show that discrete gradient flow structures associated to a finite volume
approximation of a certain class of diffusive equations (Fokker–Planck) is stable
in the limit of vanishing meshes, reproving the convergence of the scheme via
the method of evolutionary Γ-convergence and exploiting a more variational point
of view on the problem. This is based on a collaboration with Dominik Forkert
and Jan Maas. Chapter 5 represents a change of perspective, moving away from the
discrete world and reaching the non-commutative one. As in the discrete case,
we discuss how classical tools coming from the commutative optimal transport can
be translated into the setting of density matrices. In particular, in this final
chapter we present a non-commutative version of the Schrödinger problem (or entropic
regularised optimal transport problem) and discuss existence and characterisation
of minimisers, a duality result, and present a non-commutative version of the
well-known Sinkhorn algorithm to compute the above mentioned optimisers. This
is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally,
Appendix A and B contain some additional material and discussions, with particular
attention to Harnack inequalities and the regularity of flows on discrete spaces."

text: 'This work is concerned with two fascinating circuit quantum electrodynamics
components, the Josephson junction and the geometric superinductor, and the interesting
experiments that can be done by combining the two. The Josephson junction has
revolutionized the field of superconducting circuits as a non-linear dissipation-less
circuit element and is used in almost all superconducting qubit implementations
since the 90s. On the other hand, the superinductor is a relatively new circuit
element introduced as a key component of the fluxonium qubit in 2009. This is
an inductor with characteristic impedance larger than the resistance quantum and
self-resonance frequency in the GHz regime. The combination of these two elements
can occur in two fundamental ways: in parallel and in series. When connected in
parallel the two create the fluxonium qubit, a loop with large inductance and
a rich energy spectrum reliant on quantum tunneling. On the other hand placing
the two elements in series aids with the measurement of the IV curve of a single
Josephson junction in a high impedance environment. In this limit theory predicts
that the junction will behave as its dual element: the phase-slip junction. While
the Josephson junction acts as a non-linear inductor the phase-slip junction has
the behavior of a non-linear capacitance and can be used to measure new Josephson
junction phenomena, namely Coulomb blockade of Cooper pairs and phase-locked Bloch
oscillations. The latter experiment allows for a direct link between frequency
and current which is an elusive connection in quantum metrology. This work introduces
the geometric superinductor, a superconducting circuit element where the high
inductance is due to the geometry rather than the material properties of the superconductor,
realized from a highly miniaturized superconducting planar coil. These structures
will be described and characterized as resonators and qubit inductors and progress
towards the measurement of phase-locked Bloch oscillations will be presented.'

text: One key element behind the recent progress of machine learning has been the
ability to train machine learning models in large-scale distributed shared-memory
and message-passing environments. Most of these models are trained employing variants
of stochastic gradient descent (SGD) based optimization, but most methods involve
some type of consistency relaxation relative to sequential SGD, to mitigate its
large communication or synchronization costs at scale. In this paper, we introduce
a general consistency condition covering communication-reduced and asynchronous
distributed SGD implementations. Our framework, called elastic consistency, decouples
the system-specific aspects of the implementation from the SGD convergence requirements,
giving a general way to obtain convergence bounds for a wide variety of distributed
SGD methods used in practice. Elastic consistency can be used to re-derive or
improve several previous convergence bounds in message-passing and shared-memory
settings, but also to analyze new models and distribution schemes. As a direct
application, we propose and analyze a new synchronization-avoiding scheduling
scheme for distributed SGD, and show that it can be used to efficiently train
deep convolutional models for image classification.

text: Yao’s garbling scheme is one of the most fundamental cryptographic constructions.
Lindell and Pinkas (Journal of Cryptograhy 2009) gave a formal proof of security
in the selective setting where the adversary chooses the challenge inputs before
seeing the garbled circuit assuming secure symmetric-key encryption (and hence
one-way functions). This was followed by results, both positive and negative,
concerning its security in the, stronger, adaptive setting. Applebaum et al. (Crypto
2013) showed that it cannot satisfy adaptive security as is, due to a simple incompressibility
argument. Jafargholi and Wichs (TCC 2017) considered a natural adaptation of Yao’s
scheme (where the output mapping is sent in the online phase, together with the
garbled input) that circumvents this negative result, and proved that it is adaptively
secure, at least for shallow circuits. In particular, they showed that for the
class of circuits of depth δ , the loss in security is at most exponential in δ
. The above results all concern the simulation-based notion of security. In this
work, we show that the upper bound of Jafargholi and Wichs is basically optimal
in a strong sense. As our main result, we show that there exists a family of Boolean
circuits, one for each depth δ∈N , such that any black-box reduction proving
the adaptive indistinguishability of the natural adaptation of Yao’s scheme from
any symmetric-key encryption has to lose a factor that is exponential in δ√
. Since indistinguishability is a weaker notion than simulation, our bound also
applies to adaptive simulation. To establish our results, we build on the recent
approach of Kamath et al. (Eprint 2021), which uses pebbling lower bounds in conjunction
with oracle separations to prove fine-grained lower bounds on loss in cryptographic
security.

text: While messaging systems with strong security guarantees are widely used in
practice, designing a protocol that scales efficiently to large groups and enjoys
similar security guarantees remains largely open. The two existing proposals to
date are ART (Cohn-Gordon et al., CCS18) and TreeKEM (IETF, The Messaging Layer
Security Protocol, draft). TreeKEM is the currently considered candidate by the
IETF MLS working group, but dynamic group operations (i.e. adding and removing
users) can cause efficiency issues. In this paper we formalize and analyze a variant
of TreeKEM which we term Tainted TreeKEM (TTKEM for short). The basic idea underlying
TTKEM was suggested by Millican (MLS mailing list, February 2018). This version
is more efficient than TreeKEM for some natural distributions of group operations,
we quantify this through simulations.Our second contribution is two security proofs
for TTKEM which establish post compromise and forward secrecy even against adaptive
attackers. The security loss (to the underlying PKE) in the Random Oracle Model
is a polynomial factor, and a quasipolynomial one in the Standard Model. Our proofs
can be adapted to TreeKEM as well. Before our work no security proof for any TreeKEM-like
protocol establishing tight security against an adversary who can adaptively choose
the sequence of operations was known. We also are the first to prove (or even
formalize) active security where the server can arbitrarily deviate from the protocol
specification. Proving fully active security – where also the users can arbitrarily
deviate – remains open.

text: We show that Yao’s garbling scheme is adaptively indistinguishable for the
class of Boolean circuits of size S and treewidth w with only a S^O(w) loss in
security. For instance, circuits with constant treewidth are as a result adaptively
indistinguishable with only a polynomial loss. This (partially) complements a
negative result of Applebaum et al. (Crypto 2013), which showed (assuming one-way
functions) that Yao’s garbling scheme cannot be adaptively simulatable. As main
technical contributions, we introduce a new pebble game that abstracts out our
security reduction and then present a pebbling strategy for this game where the
number of pebbles used is roughly O(d w log(S)), d being the fan-out of the circuit.
The design of the strategy relies on separators, a graph-theoretic notion with
connections to circuit complexity.

text: Those who aim to devise new materials with desirable properties usually examine
present methods first. However, they will find out that some approaches can exist
only conceptually without high chances to become practically useful. It seems
that a numerical technique called automatic differentiation together with increasing
supply of computational accelerators will soon shift many methods of the material
design from the category ”unimaginable” to the category ”expensive but possible”.
Approach we suggest is not an exception. Our overall goal is to have an efficient
and generalizable approach allowing to solve inverse design problems. In this
thesis we scratch its surface. We consider jammed systems of identical particles.
And ask ourselves how the shape of those particles (or the parameters codifying
it) may affect mechanical properties of the system. An indispensable part of reaching
the answer is an appropriate particle parametrization. We come up with a simple,
yet generalizable and purposeful scheme for it. Using our generalizable shape
parameterization, we simulate the formation of a solid composed of pentagonal-like
particles and measure anisotropy in the resulting elastic response. Through automatic
differentiation techniques, we directly connect the shape parameters with the
elastic response. Interestingly, for our system we find that less isotropic particles
lead to a more isotropic elastic response. Together with other results known about
our method it seems that it can be successfully generalized for different inverse
design problems.

text: Given the abundance of applications of ranking in recent years, addressing
fairness concerns around automated ranking systems becomes necessary for increasing
the trust among end-users. Previous work on fair ranking has mostly focused on
application-specific fairness notions, often tailored to online advertising, and
it rarely considers learning as part of the process. In this work, we show how
to transfer numerous fairness notions from binary classification to a learning
to rank setting. Our formalism allows us to design methods for incorporating fairness
objectives with provable generalization guarantees. An extensive experimental
evaluation shows that our method can improve ranking fairness substantially with
no or only little loss of model quality.

text: Methods inspired from machine learning have recently attracted great interest
in the computational study of quantum many-particle systems. So far, however,
it has proven challenging to deal with microscopic models in which the total number
of particles is not conserved. To address this issue, we propose a new variant
of neural network states, which we term neural coherent states. Taking the Fröhlich
impurity model as a case study, we show that neural coherent states can learn
the ground state of non-additive systems very well. In particular, we observe
substantial improvement over the standard coherent state estimates in the most
challenging intermediate coupling regime. Our approach is generic and does not
assume specific details of the system, suggesting wide applications.

text: "Deep learning is best known for its empirical success across a wide range
of applications\r\nspanning computer vision, natural language processing and speech.
Of equal significance,\r\nthough perhaps less known, are its ramifications for
learning theory: deep networks have\r\nbeen observed to perform surprisingly well
in the high-capacity regime, aka the overfitting\r\nor underspecified regime.
Classically, this regime on the far right of the bias-variance curve\r\nis associated
with poor generalisation; however, recent experiments with deep networks\r\nchallenge
this view.\r\n\r\nThis thesis is devoted to investigating various aspects of underspecification
in deep learning.\r\nFirst, we argue that deep learning models are underspecified
on two levels: a) any given\r\ntraining dataset can be fit by many different functions,
and b) any given function can be\r\nexpressed by many different parameter configurations.
We refer to the second kind of\r\nunderspecification as parameterisation redundancy
and we precisely characterise its extent.\r\nSecond, we characterise the implicit
criteria (the inductive bias) that guide learning in the\r\nunderspecified regime.
Specifically, we consider a nonlinear but tractable classification\r\nsetting,
and show that given the choice, neural networks learn classifiers with a large
margin.\r\nThird, we consider learning scenarios where the inductive bias is not
by itself sufficient to\r\ndeal with underspecification. We then study different
ways of ‘tightening the specification’: i)\r\nIn the setting of representation
learning with variational autoencoders, we propose a hand-\r\ncrafted regulariser
based on mutual information. ii) In the setting of binary classification, we\r\nconsider
soft-label (real-valued) supervision. We derive a generalisation bound for linear\r\nnetworks
supervised in this way and verify that soft labels facilitate fast learning. Finally,
we\r\nexplore an application of soft-label supervision to the training of multi-exit
models."

text: The design and verification of concurrent systems remains an open challenge
due to the non-determinism that arises from the inter-process communication. In
particular, concurrent programs are notoriously difficult both to be written correctly
and to be analyzed formally, as complex thread interaction has to be accounted
for. The difficulties are further exacerbated when concurrent programs get executed
on modern-day hardware, which contains various buffering and caching mechanisms
for efficiency reasons. This causes further subtle non-determinism, which can
often produce very unintuitive behavior of the concurrent programs. Model checking
is at the forefront of tackling the verification problem, where the task is to
decide, given as input a concurrent system and a desired property, whether the
system satisfies the property. The inherent state-space explosion problem in model
checking of concurrent systems causes naïve explicit methods not to scale, thus
more inventive methods are required. One such method is stateless model checking
(SMC), which explores in memory-efficient manner the program executions rather
than the states of the program. State-of-the-art SMC is typically coupled with
partial order reduction (POR) techniques, which argue that certain executions
provably produce identical system behavior, thus limiting the amount of executions
one needs to explore in order to cover all possible behaviors. Another method
to tackle the state-space explosion is symbolic model checking, where the considered
techniques operate on a succinct implicit representation of the input system rather
than explicitly accessing the system. In this thesis we present new techniques
for verification of concurrent systems. We present several novel POR methods for
SMC of concurrent programs under various models of semantics, some of which account
for write-buffering mechanisms. Additionally, we present novel algorithms for
symbolic model checking of finite-state concurrent systems, where the desired
property of the systems is to ensure a formally defined notion of fairness.

text: We develop a Bayesian model (BayesRR-RC) that provides robust SNP-heritability
estimation, an alternative to marker discovery, and accurate genomic prediction,
taking 22 seconds per iteration to estimate 8.4 million SNP-effects and 78 SNP-heritability
parameters in the UK Biobank. We find that only ≤10% of the genetic variation
captured for height, body mass index, cardiovascular disease, and type 2 diabetes
is attributable to proximal regulatory regions within 10kb upstream of genes,
while 12-25% is attributed to coding regions, 32–44% to introns, and 22-28% to
distal 10-500kb upstream regions. Up to 24% of all cis and coding regions of each
chromosome are associated with each trait, with over 3,100 independent exonic
and intronic regions and over 5,400 independent regulatory regions having ≥95%
probability of contributing ≥0.001% to the genetic variance of these four traits.
Our open-source software (GMRM) provides a scalable alternative to current approaches
for biobank data.

text: "Consider a distributed task where the communication network is fixed but
the local inputs given to the nodes of the distributed system may change over
time. In this work, we explore the following question: if some of the local inputs
change, can an existing solution be updated efficiently, in a dynamic and distributed
manner?\r\nTo address this question, we define the batch dynamic CONGEST model
in which we are given a bandwidth-limited communication network and a dynamic
edge labelling defines the problem input. The task is to maintain a solution to
a graph problem on the labelled graph under batch changes. We investigate, when
a batch of alpha edge label changes arrive, - how much time as a function of alpha
we need to update an existing solution, and - how much information the nodes have
to keep in local memory between batches in order to update the solution quickly.\r\nOur
work lays the foundations for the theory of input-dynamic distributed network
algorithms. We give a general picture of the complexity landscape in this model,
design both universal algorithms and algorithms for concrete problems, and present
a general framework for lower bounds. The diverse time complexity of our model
spans from constant time, through time polynomial in alpha, and to alpha time,
which we show to be enough for any task."

text: 'We consider planning problems for graphs, Markov Decision Processes (MDPs),
and games on graphs in an explicit state space. While graphs represent the most
basic planning model, MDPs represent interaction with nature and games on graphs
represent interaction with an adversarial environment. We consider two planning
problems with k different target sets: (a) the coverage problem asks whether there
is a plan for each individual target set; and (b) the sequential target reachability
problem asks whether the targets can be reached in a given sequence. For the coverage
problem, we present a linear-time algorithm for graphs, and quadratic conditional
lower bound for MDPs and games on graphs. For the sequential target problem, we
present a linear-time algorithm for graphs, a sub-quadratic algorithm for MDPs,
and a quadratic conditional lower bound for games on graphs. Our results with
conditional lower bounds, based on the boolean matrix multiplication (BMM) conjecture
and strong exponential time hypothesis (SETH), establish (i) model-separation
results showing that for the coverage problem MDPs and games on graphs are harder
than graphs, and for the sequential reachability problem games on graphs are harder
than MDPs and graphs; and (ii) problem-separation results showing that for MDPs
the coverage problem is harder than the sequential target problem.'

text: We develop a Bayesian model (BayesRR-RC) that provides robust SNP-heritability
estimation, an alternative to marker discovery, and accurate genomic prediction,
taking 22 seconds per iteration to estimate 8.4 million SNP-effects and 78 SNP-heritability
parameters in the UK Biobank. We find that only $\leq$ 10\% of the genetic variation
captured for height, body mass index, cardiovascular disease, and type 2 diabetes
is attributable to proximal regulatory regions within 10kb upstream of genes,
while 12-25% is attributed to coding regions, 32-44% to introns, and 22-28% to
distal 10-500kb upstream regions. Up to 24% of all cis and coding regions of each
chromosome are associated with each trait, with over 3,100 independent exonic
and intronic regions and over 5,400 independent regulatory regions having >95%
probability of contributing >0.001% to the genetic variance of these four traits.
Our open-source software (GMRM) provides a scalable alternative to current approaches
for biobank data.

text: The high processing cost, poor mechanical properties and moderate performance
of Bi2Te3–based alloys used in thermoelectric devices limit the cost-effectiveness
of this energy conversion technology. Towards solving these current challenges,
in the present work, we detail a low temperature solution-based approach to produce
Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach
consists in combining proper ratios of colloidal nanoparticles and to consolidate
the resulting mixture into nanocomposites using a hot press. The transport properties
of the nanocomposites are characterized and compared with those of pure Bi2Te3
nanomaterials obtained following the same procedure. In contrast with most previous
works, the presence of Cu2-xTe nanodomains does not result in a significant reduction
of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which
is already very low. However, the introduction of Cu2-xTe yields a nearly threefold
increase of the power factor associated to a simultaneous increase of the Seebeck
coefficient and electrical conductivity at temperatures above 400 K. Taking into
account the band alignment of the two materials, we rationalize this increase
by considering that Cu2-xTe nanostructures, with a relatively low electron affinity,
are able to inject electrons into Bi2Te3, enhancing in this way its electrical
conductivity. The simultaneous increase of the Seebeck coefficient is related
to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains
associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3
heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe
nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure
of merit of Bi2Te3.

text: Astrocytes extensively infiltrate the neuropil to regulate critical aspects
of synaptic development and function. This process is regulated by transcellular
interactions between astrocytes and neurons via cell adhesion molecules. How astrocytes
coordinate developmental processes among one another to parse out the synaptic
neuropil and form non-overlapping territories is unknown. Here we identify a molecular
mechanism regulating astrocyte-astrocyte interactions during development to coordinate
astrocyte morphogenesis and gap junction coupling. We show that hepaCAM, a disease-linked,
astrocyte-enriched cell adhesion molecule, regulates astrocyte competition for
territory and morphological complexity in the developing mouse cortex. Furthermore,
conditional deletion of Hepacam from developing astrocytes significantly impairs
gap junction coupling between astrocytes and disrupts the balance between synaptic
excitation and inhibition. Mutations in HEPACAM cause megalencephalic leukoencephalopathy
with subcortical cysts in humans. Therefore, our findings suggest that disruption
of astrocyte self-organization mechanisms could be an underlying cause of neural
pathology.
