text: Under high pressures and temperatures, molecular systems with substantial
polarization charges, such as ammonia and water, are predicted to form superionic
phases and dense fluid states with dissociating molecules and high electrical
conductivity. This behaviour potentially plays a role in explaining the origin
of the multipolar magnetic fields of Uranus and Neptune, whose mantles are thought
to result from a mixture of H2O, NH3 and CH4 ices. Determining the stability domain,
melting curve and electrical conductivity of these superionic phases is therefore
crucial for modelling planetary interiors and dynamos. Here we report the melting
curve of superionic ammonia up to 300 GPa from laser-driven shock compression
of pre-compressed samples and atomistic calculations. We show that ammonia melts
at lower temperatures than water above 100 GPa and that fluid ammonia’s electrical
conductivity exceeds that of water at conditions predicted by hot, super-adiabatic
models for Uranus and Neptune, and enhances the conductivity in their fluid water-rich
dynamo layers.

text: A density wave (DW) is a fundamental type of long-range order in quantum matter
tied to self-organization into a crystalline structure. The interplay of DW order
with superfluidity can lead to complex scenarios that pose a great challenge to
theoretical analysis. In the past decades, tunable quantum Fermi gases have served
as model systems for exploring the physics of strongly interacting fermions, including
most notably magnetic ordering1, pairing and superfluidity2, and the crossover
from a Bardeen–Cooper–Schrieffer superfluid to a Bose–Einstein condensate3. Here,
we realize a Fermi gas featuring both strong, tunable contact interactions and
photon-mediated, spatially structured long-range interactions in a transversely
driven high-finesse optical cavity. Above a critical long-range interaction strength,
DW order is stabilized in the system, which we identify via its superradiant light-scattering
properties. We quantitatively measure the variation of the onset of DW order as
the contact interaction is varied across the Bardeen–Cooper–Schrieffer superfluid
and Bose–Einstein condensate crossover, in qualitative agreement with a mean-field
theory. The atomic DW susceptibility varies over an order of magnitude upon tuning
the strength and the sign of the long-range interactions below the self-ordering
threshold, demonstrating independent and simultaneous control over the contact
and long-range interactions. Therefore, our experimental setup provides a fully
tunable and microscopically controllable platform for the experimental study of
the interplay of superfluidity and DW order.

text: 'This paper establishes new connections between many-body quantum systems,
One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
(OT), by interpreting the problem of computing the ground-state energy of a finite-dimensional
composite quantum system at positive temperature as a non-commutative entropy
regularized Optimal Transport problem. We develop a new approach to fully characterize
the dual-primal solutions in such non-commutative setting. The mathematical formalism
is particularly relevant in quantum chemistry: numerical realizations of the many-electron
ground-state energy can be computed via a non-commutative version of Sinkhorn
algorithm. Our approach allows to prove convergence and robustness of this algorithm,
which, to our best knowledge, were unknown even in the two marginal case. Our
methods are based on a priori estimates in the dual problem, which we believe
to be of independent interest. Finally, the above results are extended in 1RDMFT
setting, where bosonic or fermionic symmetry conditions are enforced on the problem.'

text: In this note we study the eigenvalue growth of infinite graphs with discrete
spectrum. We assume that the corresponding Dirichlet forms satisfy certain Sobolev-type
inequalities and that the total measure is finite. In this sense, the associated
operators on these graphs display similarities to elliptic operators on bounded
domains in the continuum. Specifically, we prove lower bounds on the eigenvalue
growth and show by examples that corresponding upper bounds cannot be established.

text: "n the dynamic minimum set cover problem, the challenge is to minimize the
update time while guaranteeing a close-to-optimal min{O(log n), f} approximation
factor. (Throughout, n, m, f , and C are parameters denoting the maximum number
of elements, the number of sets, the frequency, and the cost range.) In the high-frequency
range, when f = Ω(log n) , this was achieved by a deterministic O(log n) -approximation
algorithm with O(f log n) amortized update time by Gupta et al. [Online and dynamic
algorithms for set cover, in Proceedings STOC 2017, ACM, pp. 537–550]. In this
paper we consider the low-frequency range, when f = O(log n) , and obtain deterministic
algorithms with a (1 + ∈)f -approximation ratio and the following guarantees on
the update time. (1) O ((f/∈)-log(Cn)) amortized update time: Prior to our work,
the best approximation ratio guaranteed by deterministic algorithms was O(f2)
of Bhattacharya, Henzinger, and Italiano [Design of dynamic algorithms via primal-dual
method, in Proceedings ICALP 2015, Springer, pp. 206–218]. In contrast, the only
result with O(f) -approximation was that of Abboud et al. [Dynamic set cover:
Improved algorithms and lower bounds, in Proceedings STOC 2019, ACM, pp. 114–125],
who designed a randomized (1+∈)f -approximation algorithm with amortized update
time. (2) O(f2/∈3 + (f/∈2).logC) amortized update time: This result improves the
above update time bound for most values of f\r\n in the low-frequency range, i.e.,
f=o(log n) . It is also the first result that is independent of m\r\n and n. It
subsumes the constant amortized update time of Bhattacharya and Kulkarni [Deterministically

time, in Proceedings SODA 2019, SIAM, pp. 1872–1885] for unweighted dynamic vertex
cover (i.e., when f = 2 and C = 1). (3) O((f/∈3).log2(Cn)) worst-case update time:
No nontrivial worst-case update time was previously known for the dynamic set
cover problem. Our bound subsumes and improves by a logarithmic factor the O(log3n/poly
(∈)) \r\n worst-case update time for the unweighted dynamic vertex cover problem
(i.e., when f = 2\r\n and C =1) of Bhattacharya, Henzinger, and Nanongkai [Fully
dynamic approximate maximum matching and minimum vertex cover in O(log3)n worst
case update time, in Proceedings SODA 2017, SIAM, pp. 470–489]. We achieve our
results via the primal-dual approach, by maintaining a fractional packing solution
as a dual certificate. Prior work in dynamic algorithms that employs the primal-dual
approach uses a local update scheme that maintains relaxed complementary slackness
conditions for every set. For our first result we use instead a global update
scheme that does not always maintain complementary slackness conditions. For our
second result we combine the global and the local update schema. To achieve our
third result we use a hierarchy of background schedulers. It is an interesting
open question whether this background scheduler technique can also be used to
transform algorithms with amortized running time bounds into algorithms with worst-case
running time bounds."

text: We consider the problem of learning control policies in discrete-time stochastic
systems which guarantee that the system stabilizes within some specified stabilization
region with probability 1. Our approach is based on the novel notion of stabilizing
ranking supermartingales (sRSMs) that we introduce in this work. Our sRSMs overcome
the limitation of methods proposed in previous works whose applicability is restricted
to systems in which the stabilizing region cannot be left once entered under any
control policy. We present a learning procedure that learns a control policy together
with an sRSM that formally certifies probability 1 stability, both learned as
neural networks. We show that this procedure can also be adapted to formally verifying
that, under a given Lipschitz continuous control policy, the stochastic system
stabilizes within some stabilizing region with probability 1. Our experimental
evaluation shows that our learning procedure can successfully learn provably stabilizing
policies in practice.

text: 'The Regularised Inertial Dean–Kawasaki model (RIDK) – introduced by the authors
and J. Zimmer in earlier works – is a nonlinear stochastic PDE capturing fluctuations
around the meanfield limit for large-scale particle systems in both particle density
and momentum density. We focus on the following two aspects. Firstly, we set up
a Discontinuous Galerkin (DG) discretisation scheme for the RIDK model: we provide
suitable definitions of numerical fluxes at the interface of the mesh elements
which are consistent with the wave-type nature of the RIDK model and grant stability
of the simulations, and we quantify the rate of convergence in mean square to
the continuous RIDK model. Secondly, we introduce modifications of the RIDK model
in order to preserve positivity of the density (such a feature only holds in a
“high-probability sense” for the original RIDK model). By means of numerical simulations,
we show that the modifications lead to physically realistic and positive density
profiles. In one case, subject to additional regularity constraints, we also prove
positivity. Finally, we present an application of our methodology to a system
of diffusing and reacting particles. Our Python code is available in open-source
format.'

text: Inversions are structural mutations that reverse the sequence of a chromosome
segment and reduce the effective rate of recombination in the heterozygous state.
They play a major role in adaptation, as well as in other evolutionary processes
such as speciation. Although inversions have been studied since the 1920s, they
remain difficult to investigate because the reduced recombination conferred by
them strengthens the effects of drift and hitchhiking, which in turn can obscure
signatures of selection. Nonetheless, numerous inversions have been found to be
under selection. Given recent advances in population genetic theory and empirical
study, here we review how different mechanisms of selection affect the evolution
of inversions. A key difference between inversions and other mutations, such as
single nucleotide variants, is that the fitness of an inversion may be affected
by a larger number of frequently interacting processes. This considerably complicates
the analysis of the causes underlying the evolution of inversions. We discuss
the extent to which these mechanisms can be disentangled, and by which approach.

text: The intricate regulatory processes behind actin polymerization play a crucial
role in cellular biology, including essential mechanisms such as cell migration
or cell division. However, the self-organizing principles governing actin polymerization
are still poorly understood. In this perspective article, we compare the Belousov-Zhabotinsky
(BZ) reaction, a classic and well understood chemical oscillator known for its
self-organizing spatiotemporal dynamics, with the excitable dynamics of polymerizing
actin. While the BZ reaction originates from the domain of inorganic chemistry,
it shares remarkable similarities with actin polymerization, including the characteristic
propagating waves, which are influenced by geometry and external fields, and the
emergent collective behavior. Starting with a general description of emerging
patterns, we elaborate on single droplets or cell-level dynamics, the influence
of geometric confinements and conclude with collective interactions. Comparing
these two systems sheds light on the universal nature of self-organization principles
in both living and inanimate systems.

text: The acyl-CoA-binding domain-containing protein 6 (ACBD6) is ubiquitously expressed,
plays a role in the acylation of lipids and proteins, and regulates the N-myristoylation
of proteins via N-myristoyltransferase enzymes (NMTs). However, its precise function
in cells is still unclear, as is the consequence of ACBD6 defects on human pathophysiology.
Utilizing exome sequencing and extensive international data sharing efforts, we
identified 45 affected individuals from 28 unrelated families (consanguinity 93%)
with bi-allelic pathogenic, predominantly loss-of-function (18/20) variants in
ACBD6. We generated zebrafish and Xenopus tropicalis acbd6 knockouts by CRISPR/Cas9
and characterized the role of ACBD6 on protein N-myristoylation with YnMyr chemical
proteomics in the model organisms and human cells, with the latter also being
subjected further to ACBD6 peroxisomal localization studies. The affected individuals
(23 males and 22 females), with ages ranging from 1 to 50 years old, typically
present with a complex and progressive disease involving moderate-to-severe global
developmental delay/intellectual disability (100%) with significant expressive
language impairment (98%), movement disorders (97%), facial dysmorphism (95%),
and mild cerebellar ataxia (85%) associated with gait impairment (94%), limb spasticity/hypertonia
(76%), oculomotor (71%) and behavioural abnormalities (65%), overweight (59%),
microcephaly (39%) and epilepsy (33%). The most conspicuous and common movement
disorder was dystonia (94%), frequently leading to early-onset progressive postural
deformities (97%), limb dystonia (55%), and cervical dystonia (31%). A jerky tremor
in the upper limbs (63%), a mild head tremor (59%), parkinsonism/hypokinesia developing
with advancing age (32%), and simple motor and vocal tics were among other frequent
movement disorders. Midline brain malformations including corpus callosum abnormalities
(70%), hypoplasia/agenesis of the anterior commissure (66%), short midbrain and
small inferior cerebellar vermis (38% each), as well as hypertrophy of the clava
(24%) were common neuroimaging findings. acbd6-deficient zebrafish and Xenopus
models effectively recapitulated many clinical phenotypes reported in patients
including movement disorders, progressive neuromotor impairment, seizures, microcephaly,
craniofacial dysmorphism, and midbrain defects accompanied by developmental delay
with increased mortality over time. Unlike ACBD5, ACBD6 did not show a peroxisomal
localisation and ACBD6-deficiency was not associated with altered peroxisomal
parameters in patient fibroblasts. Significant differences in YnMyr-labelling
were observed for 68 co- and 18 post-translationally N-myristoylated proteins
in patient-derived fibroblasts. N-Myristoylation was similarly affected in acbd6-deficient
zebrafish and Xenopus tropicalis models, including Fus, Marcks, and Chchd-related
proteins implicated in neurological diseases. The present study provides evidence
that bi-allelic pathogenic variants in ACBD6 lead to a distinct neurodevelopmental
syndrome accompanied by complex and progressive cognitive and movement disorders.

text: "It is a remarkable property of BCS theory that the ratio of the energy gap
at zero temperature Ξ\r\n and the critical temperature Tc is (approximately) given
by a universal constant, independent of the microscopic details of the fermionic
interaction. This universality has rigorously been proven quite recently in three
spatial dimensions and three different limiting regimes: weak coupling, low density
and high density. The goal of this short note is to extend the universal behavior
to lower dimensions d=1,2 and give an exemplary proof in the weak coupling limit."

text: Quantum state tomography is an essential component of modern quantum technology.
In application to continuous-variable harmonic-oscillator systems, such as the
electromagnetic field, existing tomography methods typically reconstruct the state
in discrete bases, and are hence limited to states with relatively low amplitudes
and energies. Here, we overcome this limitation by utilizing a feed-forward neural
network to obtain the density matrix directly in the continuous position basis.
An important benefit of our approach is the ability to choose specific regions
in the phase space for detailed reconstruction. This results in a relatively slow
scaling of the amount of resources required for the reconstruction with the state
amplitude, and hence allows us to dramatically increase the range of amplitudes
accessible with our method.

text: Motivated by a problem posed in [10], we investigate the closure operators
of the category SLatt of join semilattices and its subcategory SLattO of join
semilattices with bottom element. In particular, we show that there are only finitely
many closure operators of both categories, and provide a complete classification.
We use this result to deduce the known fact that epimorphisms of SLatt and SLattO
are surjective. We complement the paper with two different proofs of this result
using either generators or Isbell’s zigzag theorem.

text: Interactions between plants and herbivores are central in most ecosystems,
but their strength is highly variable. The amount of variability within a system
is thought to influence most aspects of plant-herbivore biology, from ecological
stability to plant defense evolution. Our understanding of what influences variability,
however, is limited by sparse data. We collected standardized surveys of herbivory
for 503 plant species at 790 sites across 116° of latitude. With these data, we
show that within-population variability in herbivory increases with latitude,
decreases with plant size, and is phylogenetically structured. Differences in
the magnitude of variability are thus central to how plant-herbivore biology varies
across macroscale gradients. We argue that increased focus on interaction variability
will advance understanding of patterns of life on Earth.

text: Methylation of CG dinucleotides (mCGs), which regulates eukaryotic genome
functions, is epigenetically propagated by Dnmt1/MET1 methyltransferases. How
mCG is established and transmitted across generations despite imperfect enzyme
fidelity is unclear. Whether mCG variation in natural populations is governed
by genetic or epigenetic inheritance also remains mysterious. Here, we show that
MET1 de novo activity, which is enhanced by existing proximate methylation, seeds
and stabilizes mCG in Arabidopsis thaliana genes. MET1 activity is restricted
by active demethylation and suppressed by histone variant H2A.Z, producing localized
mCG patterns. Based on these observations, we develop a stochastic mathematical
model that precisely recapitulates mCG inheritance dynamics and predicts intragenic
mCG patterns and their population-scale variation given only CG site spacing.
Our results demonstrate that intragenic mCG establishment, inheritance, and variance
constitute a unified epigenetic process, revealing that intragenic mCG undergoes
large, millennia-long epigenetic fluctuations and can therefore mediate evolution
on this timescale.

text: Regulation of the Arp2/3 complex is required for productive nucleation of
branched actin networks. An emerging aspect of regulation is the incorporation
of subunit isoforms into the Arp2/3 complex. Specifically, both ArpC5 subunit
isoforms, ArpC5 and ArpC5L, have been reported to fine-tune nucleation activity
and branch junction stability. We have combined reverse genetics and cellular
structural biology to describe how ArpC5 and ArpC5L differentially affect cell
migration. Both define the structural stability of ArpC1 in branch junctions and,
in turn, by determining protrusion characteristics, affect protein dynamics and
actin network ultrastructure. ArpC5 isoforms also affect the positioning of members
of the Ena/Vasodilator-stimulated phosphoprotein (VASP) family of actin filament
elongators, which mediate ArpC5 isoform–specific effects on the actin assembly
level. Our results suggest that ArpC5 and Ena/VASP proteins are part of a signaling
pathway enhancing cell migration.

text: "Regulation of the Arp2/3 complex is required for productive nucleation of
branched actin networks. An emerging aspect of regulation is the incorporation
of subunit isoforms into the Arp2/3 complex. Specifically, both ArpC5 subunit
isoforms, ArpC5 and ArpC5L, have been reported to fine-tune nucleation activity
and branch junction stability. We have combined reverse genetics and cellular
structural biology to describe how ArpC5 and ArpC5L differentially affect cell
migration. Both define the structural stability of ArpC1 in branch junctions and,
in turn, by determining protrusion characteristics, affect protein dynamics and
actin network ultrastructure. ArpC5 isoforms also affect the positioning of members
of the Ena/Vasodilator-stimulated phosphoprotein (VASP) family of actin filament
elongators, which mediate ArpC5 isoform–specific effects on the actin assembly
level. Our results suggest that ArpC5 and Ena/VASP proteins are part of a signaling
pathway enhancing cell migration.\r\n"

text: A precise quantitative description of the ultrastructural characteristics
underlying biological mechanisms is often key to their understanding. This is
particularly true for dynamic extra- and intracellular filamentous assemblies,
playing a role in cell motility, cell integrity, cytokinesis, tissue formation
and maintenance. For example, genetic manipulation or modulation of actin regulatory
proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural
architecture of actin filament-rich cell peripheral structures, such as lamellipodia
or filopodia. However, the observed ultrastructural effects often remain subtle
and require sufficiently large datasets for appropriate quantitative analysis.
The acquisition of such large datasets has been enabled by recent advances in
high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates
the development of complementary approaches to maximize the extraction of relevant
biological information. We have developed a computational toolbox for the semi-automatic
quantification of segmented and vectorized fila- mentous networks from pre-processed
cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple
experimental conditions. GUI-based components simplify the processing of data
and allow users to obtain a large number of ultrastructural parameters describing
filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing
cryo-ET data of untreated and chemically perturbed branched actin filament networks
and that of parallel actin filament arrays. In principle, the computational toolbox
presented here is applicable for data analysis comprising any type of filaments
in regular (i.e. parallel) or random arrangement. We show that it can ease the
identification of key differences between experimental groups and facilitate the
in-depth analysis of ultrastructural data in a time-efficient manner.

text: Motile cells moving in multicellular organisms encounter microenvironments
of locally heterogeneous mechanochemical composition. Individual compositional
parameters like chemotactic signals, adhesiveness, and pore sizes are well known
to be sensed by motile cells, providing individual guidance cues for cellular
pathfinding. However, motile cells encounter diverse mechanochemical signals at
the same time, raising the question of how cells respond to locally diverse and
potentially competing signals on their migration routes. Here, we reveal that
motile amoeboid cells require nuclear repositioning, termed nucleokinesis, for
adaptive pathfinding in heterogeneous mechanochemical microenvironments. Using
mammalian immune cells and the amoebaDictyostelium discoideum,
we discover that frequent, rapid and long-distance nucleokinesis is a basic component
of amoeboid pathfinding, enabling cells to reorientate quickly between locally
competing cues. Amoeboid nucleokinesis comprises a two-step cell polarity switch
and is driven by myosin II-forces, sliding the nucleus from a ‘losing’ to the
‘winning’ leading edge to re-adjust the nuclear to the cellular path. Impaired
nucleokinesis distorts fast path adaptions and causes cellular arrest in the microenvironment.
Our findings establish that nucleokinesis is required for amoeboid cell navigation.
Given that motile single-cell amoebae, many immune cells, and some cancer cells
utilize an amoeboid migration strategy, these results suggest that amoeboid nucleokinesis
underlies cellular navigation during unicellular biology, immunity, and disease.

text: AbstractEndomembrane damage represents a
form of stress that is detrimental for eukaryotic cells1,2.
To cope with this threat, cells possess mechanisms that repair the damage and
restore cellular homeostasis3–7. Endomembrane damage also
results in organelle instability and the mechanisms by which cells stabilize damaged
endomembranes to enable membrane repair remains unknown. Here, by combining in
vitro and in cellulo studies with computational modelling we uncover a biological
function for stress granules whereby these biomolecular condensates form rapidly
at endomembrane damage sites and act as a plug that stabilizes the ruptured membrane.
Functionally, we demonstrate that stress granule formation and membrane stabilization
enable efficient repair of damaged endolysosomes, through both ESCRT (endosomal
sorting complex required for transport)-dependent and independent mechanisms.
We also show that blocking stress granule formation in human macrophages creates
a permissive environment for Mycobacterium tuberculosis,
a human pathogen that exploits endomembrane damage to survive within the host.

text: "Data related to the following paper:\r\n\"Stress granules plug and stabilize
damaged endolysosomal membranes\" (https://doi.org/10.1038/s41586-023-06726-w)\r\n\r\nAbstract:
\r\nEndomembrane damage represents a form of stress that is detrimental for eukaryotic
cells. To cope with this threat, cells possess mechanisms that repair the damage
and restore cellular homeostasis. Endomembrane damage also results in organelle
instability and the mechanisms by which cells stabilize damaged endomembranes
to enable membrane repair remains unknown. In this work we use a minimal coarse-grained
molecular dynamics system to explore how lipid vesicles undergoing poration in
a protein-rich medium can be plugged and stabilised by condensate formation. The
solution of proteins in and out of the vesicle is described by beads dispersed
in implicit solvent. The membrane is described as a one-bead-thick fluid elastic
layer of mechanical properties that mimic biological membranes. We tune the interactions
between solution beads in the different compartments to capture the differences
between the cytoplasmic and endosomal protein solutions and explore how the system
responds to different degrees of membrane poration. We find that, in the right
interaction regime, condensates form rapidly at the damage site upon solution
mixing and act as a plug that prevents futher mixing and destabilisation of the
vesicle. Further, when the condensate can interact with the membrane (wetting
interactions) we find that it mediates pore sealing and membrane repair. This
research is part of the work published in \"Stress granules plug and stabilize
damaged endolysosomal membranes\", Bussi et al, Nature, 2023 - 10.1038/s41586-023-06726-w."

text: Muscle degeneration is the most prevalent cause for frailty and dependency
in inherited diseases and ageing. Elucidation of pathophysiological mechanisms,
as well as effective treatments for muscle diseases, represents an important goal
in improving human health. Here, we show that the lipid synthesis enzyme phosphatidylethanolamine
cytidyltransferase (PCYT2/ECT) is critical to muscle health. Human deficiency
in PCYT2 causes a severe disease with failure to thrive and progressive weakness.
pcyt2-mutant zebrafish and muscle-specific Pcyt2-knockout mice recapitulate the
participant phenotypes, with failure to thrive, progressive muscle weakness and
accelerated ageing. Mechanistically, muscle Pcyt2 deficiency affects cellular
bioenergetics and membrane lipid bilayer structure and stability. PCYT2 activity
declines in ageing muscles of mice and humans, and adeno-associated virus-based
delivery of PCYT2 ameliorates muscle weakness in Pcyt2-knockout and old mice,
offering a therapy for individuals with a rare disease and muscle ageing. Thus,
PCYT2 plays a fundamental and conserved role in vertebrate muscle health, linking
PCYT2 and PCYT2-synthesized lipids to severe muscle dystrophy and ageing.

text: The phonon transport mechanisms and ultralow lattice thermal conductivities
(κL) in silver halide AgX (X=Cl,Br,I) compounds are not yet well understood. Herein,
we study the lattice dynamics and thermal property of AgX under the framework
of perturbation theory and the two-channel Wigner thermal transport model based
on accurate machine learning potentials. We find that an accurate extraction of
the third-order atomic force constants from largely displaced configurations is
significant for the calculation of the κL of AgX, and the coherence thermal transport
is also non-negligible. In AgI, however, the calculated κL still considerably
overestimates the experimental values even including four-phonon scatterings.
Molecular dynamics (MD) simulations using machine learning potential suggest an
important role of the higher-than-fourth-order lattice anharmonicity in the low-frequency
phonon linewidths of AgI at room temperature, which can be related to the simultaneous
restrictions of the three- and four-phonon phase spaces. The κL of AgI calculated
using MD phonon lifetimes including full-order lattice anharmonicity shows a better
agreement with experiments.

text: "Distributed Key Generation (DKG) is a technique to bootstrap threshold cryptosystems
without a trusted party. DKG is an essential building block to many decentralized
protocols such as randomness beacons, threshold signatures, Byzantine consensus,
and multiparty computation. While significant progress has been made recently,
existing asynchronous DKG constructions are inefficient when the reconstruction
threshold is larger than one-third of the total nodes. In this paper, we present
a simple and concretely efficient asynchronous DKG (ADKG) protocol among n = 3t
+ 1 nodes that can tolerate up to t malicious nodes and support any reconstruction
threshold ℓ ≥ t. Our protocol has an expected O(κn3) communication cost, where
κ is the security parameter, and only assumes the hardness of the Discrete Logarithm.
The\r\ncore ingredient of our ADKG protocol is an asynchronous protocol to secret
share a random polynomial of degree ℓ ≥ t, which has other applications, such
as asynchronous proactive secret sharing and asynchronous multiparty computation.
We implement our high-threshold ADKG protocol and evaluate it using a network
of up to 128 geographically distributed nodes. Our evaluation shows that our high-threshold
ADKG protocol reduces the running time by 90% and bandwidth usage by 80% over
the state-of-the-art."

text: Computing the solubility of crystals in a solvent using atomistic simulations
is notoriously challenging due to the complexities and convergence issues associated
with free-energy methods, as well as the slow equilibration in direct-coexistence
simulations. This paper introduces a molecular-dynamics workflow that simplifies
and robustly computes the solubility of molecular or ionic crystals. This method
is considerably more straightforward than the state-of-the-art, as we have streamlined
and optimised each step of the process. Specifically, we calculate the chemical
potential of the crystal using the gas-phase molecule as a reference state, and
employ the S0 method to determine the concentration dependence of the chemical
potential of the solute. We use this workflow to predict the solubilities of sodium
chloride in water, urea polymorphs in water, and paracetamol polymorphs in both
water and ethanol. Our findings indicate that the predicted solubility is sensitive
to the chosen potential energy surface. Furthermore, we note that the harmonic
approximation often fails for both molecular crystals and gas molecules at or
above room temperature, and that the assumption of an ideal solution becomes less
valid for highly soluble substances.

text: Sex chromosomes have evolved independently multiple times, but why some are
conserved for more than 100 million years whereas others turnover rapidly remains
an open question. Here, we examine the homology of sex chromosomes across nine
orders of insects, plus the outgroup springtails. We find that the X chromosome
is likely homologous across insects and springtails; the only exception is in
the Lepidoptera, which has lost the X and now has a ZZ/ZW sex-chromosome system.
These results suggest the ancestral insect X chromosome has persisted for more
than 450 million years—the oldest known sex chromosome to date. Further, we propose
that the shrinking of gene content the dipteran X chromosome has allowed for a
burst of sex-chromosome turnover that is absent from other speciose insect orders.

text: Sex chromosomes have evolved independently multiple times, but why some are
conserved for more than 100 million years whereas others turnover rapidly remains
an open question. Here, we examine the homology of sex chromosomes across nine
orders of insects, plus the outgroup springtails. We find that the X chromosome
is likely homologous across insects and springtails; the only exception is in
the Lepidoptera, which has lost the X and now has a ZZ/ZW sex chromosome system.
These results suggest the ancestral insect X chromosome has persisted for more
than 450 million years – the oldest known sex chromosome to date. Further, we
propose that the shrinking of gene content of the Dipteran X chromosome has allowed
for a burst of sex-chromosome turnover that is absent from other speciose insect
orders.

text: Cumulus parameterization (CP) in state‐of‐the‐art global climate models is
based on the quasi‐equilibrium assumption (QEA), which views convection as the
action of an ensemble of cumulus clouds, in a state of equilibrium with respect
to a slowly varying atmospheric state. This view is not compatible with the organization
and dynamical interactions across multiple scales of cloud systems in the tropics
and progress in this research area was slow over decades despite the widely recognized
major shortcomings. Novel ideas on how to represent key physical processes of
moist convection‐large‐scale interaction to overcome the QEA have surged recently.
The stochastic multicloud model (SMCM) CP in particular mimics the dynamical interactions
of multiple cloud types that characterize organized tropical convection. Here,
the SMCM is used to modify the Zhang‐McFarlane (ZM) CP by changing the way in
which the bulk mass flux and bulk entrainment and detrainment rates are calculated.
This is done by introducing a stochastic ensemble of plumes characterized by randomly
varying detrainment level distributions based on the cloud area fraction of the
SMCM. The SMCM is here extended to include shallow cumulus clouds resulting in
a unified shallow‐deep CP. The new stochastic multicloud plume CP is validated
against the control ZM scheme in the context of the single column Community Climate
Model of the National Center for Atmospheric Research using data from both tropical
ocean and midlatitude land convection. Some key features of the SMCM CP such as
it capability to represent the tri‐modal nature of organized convection are emphasized.

text: Experiments have shown that charge distributions of granular materials are
non-Gaussian, with broad tails that indicate many particles with high charge.
This observation has consequences for the behavior of granular materials in many
settings, and may bear relevance to the underlying charge transfer mechanism.
However, there is the unaddressed possibility that broad tails arise due to experimental
uncertainties, as determining the shapes of tails is nontrivial. Here we show
that measurement uncertainties can indeed account for most of the tail broadening
previously observed. The clue that reveals this is that distributions are sensitive
to the electric field at which they are measured; ones measured at low (high)
fields have larger (smaller) tails. Accounting for sources of uncertainty, we
reproduce this broadening in silico. Finally, we use our results to back out the
true charge distribution without broadening, which we find is still non-Guassian,
though with substantially different behavior at the tails and indicating significantly
fewer highly charged particles. These results have implications in many natural
settings where electrostatic interactions, especially among highly charged particles,
strongly affect granular behavior.

text: "We consider a natural problem dealing with weighted packet selection across
a rechargeable link, which e.g., finds applications in cryptocurrency networks.
The capacity of a link (u, v) is determined by how much nodes u and v allocate
for this link. Specifically, the input is a finite ordered sequence of packets
that arrive in both directions along a link. Given (u, v) and a packet of weight
x going from u to v, node u can either accept or reject the packet. If u accepts
the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity
on (u, v) increases by x. If a node rejects the packet, this will entail a cost
affinely linear in the weight of the packet. A link is “rechargeable” in the sense
that the total capacity of the link has to remain constant, but the allocation
of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions.
The goal is to minimise the sum of the capacity injected into the link and the
cost of rejecting packets. We show that the problem is NP-hard, but can be approximated
efficiently with a ratio of (1+ε)⋅(1+3–√) for some arbitrary ε>0.\r\n."

text: "Payment channel networks are a promising approach to improve the scalability
bottleneck\r\nof cryptocurrencies. Two design principles behind payment channel
networks are\r\nefficiency and privacy. Payment channel networks improve efficiency
by allowing users\r\nto transact in a peer-to-peer fashion along multi-hop routes
in the network, avoiding\r\nthe lengthy process of consensus on the blockchain.
Transacting over payment channel\r\nnetworks also improves privacy as these transactions
are not broadcast to the blockchain.\r\nDespite the influx of recent protocols
built on top of payment channel networks and\r\ntheir analysis, a common shortcoming
of many of these protocols is that they typically\r\nfocus only on either improving
efficiency or privacy, but not both. Another limitation\r\non the efficiency front
is that the models used to model actions, costs and utilities of\r\nusers are
limited or come with unrealistic assumptions.\r\nThis thesis aims to address some
of the shortcomings of recent protocols and algorithms\r\non payment channel networks,
particularly in their privacy and efficiency aspects. We\r\nfirst present a payment
route discovery protocol based on hub labelling and private\r\ninformation retrieval
that hides the route query and is also efficient. We then present\r\na rebalancing
protocol that formulates the rebalancing problem as a linear program\r\nand solves
the linear program using multiparty computation so as to hide the channel\r\nbalances.
The rebalancing solution as output by our protocol is also globally optimal.\r\nWe
go on to develop more realistic models of the action space, costs, and utilities
of\r\nboth existing and new users that want to join the network. In each of these
settings,\r\nwe also develop algorithms to optimise the utility of these users
with good guarantees\r\non the approximation and competitive ratios."

text: Payment channel networks (PCNs) are a promising solution to the scalability
problem of cryptocurrencies. Any two users connected by a payment channel in the
network can theoretically send an unbounded number of instant, costless transactions
between them. Users who are not directly connected can also transact with each
other in a multi-hop fashion. In this work, we study the incentive structure behind
the creation of payment channel networks, particularly from the point of view
of a single user that wants to join the network. We define a utility function
for a new user in terms of expected revenue, expected fees, and the cost of creating
channels, and then provide constant factor approximation algorithms that optimise
the utility function given a certain budget. Additionally, we take a step back
from a single user to the whole network and examine the parameter spaces under
which simple graph topologies form a Nash equilibrium.

text: "Most motions of many-body systems at any scale in nature with sufficient
degrees\r\nof freedom tend to be chaotic; reaching from the orbital motion of
planets, the air\r\ncurrents in our atmosphere, down to the water flowing through
our pipelines or\r\nthe movement of a population of bacteria. To the observer
it is therefore intriguing\r\nwhen a moving collective exhibits order. Collective
motion of flocks of birds, schools\r\nof fish or swarms of self-propelled particles
or robots have been studied extensively\r\nover the past decades but the mechanisms
involved in the transition from chaos to\r\norder remain unclear. Here, the interactions,
that in most systems give rise to chaos,\r\nsustain order. In this thesis we investigate
mechanisms that preserve, destabilize\r\nor lead to the ordered state. We show
that endothelial cells migrating in circular\r\nconfinements transition to a collective
rotating state and concomitantly synchronize\r\nthe frequencies of nucleating
actin waves within individual cells. Consequently,\r\nthe frequency dependent
cell migration speed uniformizes across the population.\r\nComplementary to the
WAVE dependent nucleation of traveling actin waves, we\r\nshow that in leukocytes
the actin polymerization depending on WASp generates\r\npushing forces locally
at stationary patches. Next, in pipe flows, we study methods\r\nto disrupt the
self–sustaining cycle of turbulence and therefore relaminarize the\r\nflow. While
we find in pulsating flow conditions that turbulence emerges through a\r\nhelical
instability during the decelerating phase. Finally, we show quantitatively in\r\nbrain
slices of mice that wild-type control neurons can compensate the migratory\r\ndeficits
of a genetically modified neuronal sub–population in the developing cortex."

text: "Superconductor-semiconductor heterostructures currently capture a significant
amount of research interest and they serve as the physical platform in many proposals
towards topological quantum computation.\r\nDespite being under extensive investigations,
historically using transport techniques, the basic properties of the interface
between the superconductor and the semiconductor remain to be understood.\r\n\r\nIn
this thesis, two separate studies on the Al-InAs heterostructures are reported
with the first focusing on the physics of the material motivated by the emergence
of a new phase, the Bogoliubov-Fermi surface. \r\nThe second focuses on a technological
application, a gate-tunable Josephson parametric amplifier.\r\n\r\nIn the first
study, we investigate the hypothesized unconventional nature of the induced superconductivity
at the interface between the Al thin film and the InAs quantum well.\r\nWe embed
a two-dimensional Al-InAs hybrid system in a resonant microwave circuit allowing
measurements of change in inductance.\r\nThe behaviour of the resonance in a range
of temperature and in-plane magnetic field has been studied and compared with
the theory of conventional s-wave superconductor and a two-component theory that
includes both contribution of the $s$-wave pairing in Al and the intraband $p
\\pm ip$ pairing in InAs.\r\nMeasuring the temperature dependence of resonant
frequency, no discrepancy is found between data and the conventional theory.\r\nWe
observe the breakdown of superconductivity due to an applied magnetic field which
contradicts the conventional theory.\r\nIn contrast, the data can be captured
quantitatively by fitting to a two-component model.\r\nWe find the evidence of
the intraband $p \\pm ip$ pairing in the InAs and the emergence of the Bogoliubov-Fermi
surfaces due to magnetic field with the characteristic value $B^* = 0.33~\\mathrm{T}$.\r\nFrom
the fits, the sheet resistance of Al, the carrier density and mobility in InAs
are determined.\r\nBy systematically studying the anisotropy of the circuit response,
we find weak anisotropy for $B < B^*$ and increasingly strong anisotropy for $B
> B^*$ resulting in a pronounced two-lobe structure in polar plot of frequency
versus field angle.\r\nStrong resemblance between the field dependence of dissipation
and superfluid density hints at a hidden signature of the Bogoliubov-Fermi surface
that is burried in the dissipation data.\r\n\r\nIn the second study, we realize
a parametric amplifier with a Josephson field effect transistor as the active
element.\r\nThe device's modest construction consists of a gated SNS weak link
embedded at the center of a coplanar waveguide resonator.\r\nBy applying a gate
voltage, the resonant frequency is field-effect tunable over a range of 2 GHz.\r\nModelling
the JoFET minimally as a parallel RL circuit, the dissipation introduced by the
JoFET can be quantitatively related to the gate voltage.\r\nWe observed gate-tunable
Kerr nonlinearity qualitatively in line with expectation.\r\nThe JoFET amplifier
has 20 dB of gain, 4 MHz of instantaneous bandwidth, and a 1dB compression point
of -125.5 dBm when operated at a fixed resonant frequency.\r\nIn general, the
signal-to-noise ratio is improved by 5-7 dB when the JoFET amplifier is activated
compared.\r\nThe noise of the measurement chain and insertion loss of relevant
circuit elements are calibrated to determine the expected and the real noise performance
of the JoFET amplifier.\r\nAs a quantification of the noise performance, the measured
total input-referred noise of the JoFET amplifier is in good agreement with the
estimated expectation which takes device loss into account.\r\nWe found that the
noise performance of the device reported in this document approaches one photon
of total input-referred added noise which is the quantum limit imposed in nondegenerate
parametric amplifier."

text: Clathrin-mediated endocytosis (CME) is vital for the regulation of plant growth
and development by controlling plasma membrane protein composition and cargo uptake.
CME relies on the precise recruitment of regulators for vesicle maturation and
release. Homologues of components of mammalian vesicle scission are strong candidates
to be part of the scissin machinery in plants, but the precise roles of these
proteins in this process is not fully understood. Here, we characterised the roles
of Plant Dynamin-Related Proteins 2 (DRP2s) and SH3-domain containing protein
2 (SH3P2), the plant homologue to Dynamins’ recruiters, like Endophilin and Amphiphysin,
in the CME by combining high-resolution imaging of endocytic events in vivo and
characterisation of the purified proteins in vitro. Although DRP2s and SH3P2 arrive
similarly late during CME and physically interact, genetic analysis of the Dsh3p1,2,3
triple-mutant and complementation assays with non-SH3P2-interacting DRP2 variants
suggests that SH3P2 does not directly recruit DRP2s to the site of endocytosis.
These observations imply that despite the presence of many well-conserved endocytic
components, plants have acquired a distinct mechanism for CME. One Sentence Summary
In contrast to predictions based on mammalian systems, plant Dynamin-related proteins
2 are recruited to the site of Clathrin-mediated endocytosis independently of
BAR-SH3 proteins.

text: "Background: Biallelic variants in OGDHL, encoding part of the α-ketoglutarate
dehydrogenase complex, have been associated with highly heterogeneous neurological
and neurodevelopmental disorders. However, the validity of this association remains
to be confirmed. A second OGDHL patient cohort was recruited to carefully assess
the gene-disease relationship.\r\nMethods: Using an unbiased genotype-first approach,
we screened large, multiethnic aggregated sequencing datasets worldwide for biallelic
OGDHL variants. We used CRISPR/Cas9 to generate zebrafish knockouts of ogdhl,
ogdh paralogs, and dhtkd1 to investigate functional relationships and impact during
development. Functional complementation with patient variant transcripts was conducted
to systematically assess protein functionality as a readout for pathogenicity.\r\nResults:
A cohort of 14 individuals from 12 unrelated families exhibited highly variable
clinical phenotypes, with the majority of them presenting at least one additional
variant, potentially accounting for a blended phenotype and complicating phenotypic
understanding. We also uncovered extreme clinical heterogeneity and high allele
frequencies, occasionally incompatible with a fully penetrant recessive disorder.
Human cDNA of previously described and new variants were tested in an ogdhl zebrafish
knockout model, adding functional evidence for variant reclassification. We disclosed
evidence of hypomorphic alleles as well as a loss-of-function variant without
deleterious effects in zebrafish variant testing also showing discordant familial
segregation, challenging the relationship of OGDHL as a conventional Mendelian
gene. Going further, we uncovered evidence for a complex compensatory relationship
among OGDH, OGDHL, and DHTKD1 isoenzymes that are associated with neurodevelopmental
disorders and exhibit complex transcriptional compensation patterns with partial
functional redundancy.\r\nConclusions: Based on the results of genetic, clinical,
and functional studies, we formed three hypotheses in which to frame observations:
biallelic OGDHL variants lead to a highly variable monogenic disorder, variants
in OGDHL are following a complex pattern of inheritance, or they may not be causative
at all. Our study further highlights the continuing challenges of assessing the
validity of reported disease-gene associations and effects of variants identified
in these genes. This is particularly more complicated in making genetic diagnoses
based on identification of variants in genes presenting a highly heterogenous
phenotype such as “OGDHL-related disorders”."

text: We introduce a compact, intuitive procedural graph representation for cellular
metamaterials, which are small-scale, tileable structures that can be architected
to exhibit many useful material properties. Because the structures’ “architectures”
vary widely—with elements such as beams, thin shells, and solid bulks—it is difficult
to explore them using existing representations. Generic approaches like voxel
grids are versatile, but it is cumbersome to represent and edit individual structures;
architecture-specific approaches address these issues, but are incompatible with
one another. By contrast, our procedural graph succinctly represents the construction
process for any structure using a simple skeleton annotated with spatially varying
thickness. To express the highly constrained triply periodic minimal surfaces
(TPMS) in this manner, we present the first fully automated version of the conjugate
surface construction method, which allows novices to create complex TPMS from
intuitive input. We demonstrate our representation’s expressiveness, accuracy,
and compactness by constructing a wide range of established structures and hundreds
of novel structures with diverse architectures and material properties. We also
conduct a user study to verify our representation’s ease-of-use and ability to
expand engineers’ capacity for exploration.

text: Transcription by RNA polymerase II (Pol II) can be repressed by noncoding
RNA, including the human RNA Alu. However, the mechanism by which endogenous RNAs
repress transcription remains unclear. Here we present cryo-electron microscopy
structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA
and RNA bind to Pol II during transcription elongation. Further, we show how domains
of the general transcription factor TFIIF affect complex dynamics and control
repressive activity. Together, we reveal how a non-coding RNA can regulate mammalian
gene expression.

text: "We investigate spin-charge separation of a spin-\r\n1\r\n2\r\n Fermi system
confined in a triple well where multiple bands are occupied. We assume that our
finite fermionic system is close to fully spin polarized while being doped by
a hole and an impurity fermion with opposite spin. Our setup involves ferromagnetic
couplings among the particles in different bands, leading to the development of
strong spin-transport correlations in an intermediate interaction regime. Interactions
are then strong enough to lift the degeneracy among singlet and triplet spin configurations
in the well of the spin impurity but not strong enough to prohibit hole-induced
magnetic excitations to the singlet state. Despite the strong spin-hole correlations,
the system exhibits spin-charge deconfinement allowing for long-range entanglement
of the spatial and spin degrees of freedom."

text: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e.,
impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the
impurity-boson interaction. We show that the dipolar nature of the condensate
and of the impurity results in anisotropic relaxation dynamics, in particular,
anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench
dynamics is strongly affected by the interplay between dipolar anisotropy and
trap geometry. Our findings pave the way for simulating impurities in anisotropic
media utilizing experiments with dipolar mixtures.

text: 'Mass spectrometry imaging (MSI) is a powerful analytical technique for the
two-dimensional (2D) localization of chemicals on surfaces. Conventional MSI experiments
require to predefine the surface of interest based on photographic or microscopic
images. Typically, these boundaries can no longer be changed or adjusted once
the experiment has been started. In terms of a more interactive approach we recently
developed a pen-like ionization interface which is directly connected to the mass
spectrometer. The device allows the user to ionize chemicals by desorption electrospray
ionization (DESI) and to freely move the interface over a surface of interest.
A mini camera, which is mounted on the tip of the pen, magnifies the desorption
area and enables a simple positioning of the pen. The combination of optical data
from the camera module and chemical data obtained by mass analysis facilitates
a novel type of imaging experiment: interactive mass spectrometry imaging (IMSI).
For this application, we present a novel approach for a robust, optical flow-based
motion detection. While the live video stream from the camera is used to track
the pen''s motion across the surface a post-acquisition algorithm correlates the
coordinates of the pen trajectory with respective mass spectra obtained from a
simultaneous mass spectrometric data acquisition. This algorithm is no longer
dependent on a single, manually applied optical marker on the sample surface,
which has to be visible on all video frames throughout the analysis. The advanced
DESI-IMSI method was successfully tested on inkjet-printed letters as well as
mouse brain tissue samples. Validation of the results was done by comparing DESI-IMSI
with standard DESI-MSI data.'

text: In the developing vertebrate central nervous system, neurons and glia typically
arise sequentially from common progenitors. Here, we report that the transcription
factor Forkhead Box G1 (Foxg1) regulates gliogenesis in the mouse neocortex via
distinct cell-autonomous roles in progenitors and in postmitotic neurons that
regulate different aspects of the gliogenic FGF signalling pathway. We demonstrate
that loss of Foxg1 in cortical progenitors at neurogenic stages causes premature
astrogliogenesis. We identify a novel FOXG1 target, the pro-gliogenic FGF pathway
component Fgfr3, which is suppressed by FOXG1 cell-autonomously to maintain neurogenesis.
Furthermore, FOXG1 can also suppress premature astrogliogenesis triggered by the
augmentation of FGF signalling. We identify a second novel function of FOXG1 in
regulating the expression of gliogenic ligand FGF18 in new born neocortical upper-layer
neurons. Loss of FOXG1 in postmitotic neurons increases Fgf18 expression and enhances
gliogenesis in the progenitors. These results fit well with the model that new
born neurons secrete cues that trigger progenitors to produce the next wave of
cell types, astrocytes. If FGF signalling is attenuated in Foxg1 null progenitors,
they progress to oligodendrocyte production. Therefore, loss of FOXG1 transitions
the progenitor to a gliogenic state, producing either astrocytes or oligodendrocytes
depending on FGF signalling levels. Our results uncover how FOXG1 integrates extrinsic
signalling via the FGF pathway to regulate the sequential generation of neurons,
astrocytes, and oligodendrocytes in the cerebral cortex.

text: The kinetics of the assembly of semiflexible filaments through end-to-end
annealing is key to the structure of the cytoskeleton, but is not understood.
We analyze this problem through scaling theory and simulations, and uncover a
regime where filaments’ ends find each other through bending fluctuations without
the need for the whole filament to diffuse. This results in a very substantial
speedup of assembly in physiological regimes, and could help with understanding
the dynamics of actin and intermediate filaments in biological processes such
as wound healing and cell division.

text: "The classical Steinitz theorem states that if the origin belongs to the interior
of the convex hull of a set \U0001D446⊂ℝ\U0001D451, then there are at most 2\U0001D451
points of \U0001D446 whose convex hull contains the origin in the interior. Bárány,
Katchalski,and Pach proved the following quantitative version of Steinitz’s theorem.
Let \U0001D444 be a convex polytope in ℝ\U0001D451 containing the standard Euclidean
unit ball \U0001D401\U0001D451. Then there exist at most 2\U0001D451 vertices
of \U0001D444 whose convex hull \U0001D444′ satisfies \U0001D45F\U0001D401\U0001D451⊂\U0001D444′
with \U0001D45F⩾\U0001D451−2\U0001D451. They conjectured that \U0001D45F⩾\U0001D450\U0001D451−1∕2
holds with a universal constant \U0001D450>0. We prove \U0001D45F⩾15\U0001D4512,
the first polynomial lower bound on \U0001D45F. Furthermore, we show that \U0001D45F
is not greater than 2/√\U0001D451."

text: So-called spontaneous activity is a central hallmark of most nervous systems.
Such non-causal firing is contrary to the tenet of spikes as a means of communication,
and its purpose remains unclear. We propose that self-initiated firing can serve
as a release valve to protect neurons from the toxic conditions arising in mitochondria
from lower-than-baseline energy consumption. To demonstrate the viability of our
hypothesis, we built a set of models that incorporate recent experimental results
indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP),
adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing.
We explore the relationship of metabolic cost of spiking with its effect on the
temporal patterning of spikes and reproduce experimentally observed changes in
intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with
ROS-modulated potassium channels. We also show that metabolic spiking homeostasis
can produce indefinitely sustained avalanche dynamics in cortical circuits. Our
theory can account for key features of neuronal activity observed in many studies
ranging from ion channel function all the way to resting state dynamics. We finish
with a set of experimental predictions that would confirm an integrated, crucial
role for metabolically regulated spiking and firmly link metabolic homeostasis
and neuronal function.
