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: 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: 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: "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
maintaining a (2 + ∈) -approximate minimum vertex cover in O(1/∈2) amortized update
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: "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: 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: "This thesis concerns the application of variational methods to the study
of evolution problems arising in fluid mechanics and in material sciences. The
main focus is on weak-strong stability properties of some curvature driven interface
evolution problems, such as the two-phase Navier–Stokes flow with surface tension
and multiphase mean curvature flow, and on the phase-field approximation of the
latter. Furthermore, we discuss a variational approach to the study of a class
of doubly nonlinear wave equations.\r\nFirst, we consider the two-phase Navier–Stokes
flow with surface tension within a bounded domain. The two fluids are immiscible
and separated by a sharp interface, which intersects the boundary of the domain
at a constant contact angle of ninety degree. We devise a suitable concept of
varifolds solutions for the associated interface evolution problem and we establish
a weak-strong uniqueness principle in case of a two dimensional ambient space.
In order to focus on the boundary effects and on the singular geometry of the
evolving domains, we work for simplicity in the regime of same viscosities for
the two fluids.\r\nThe core of the thesis consists in the rigorous proof of the
convergence of the vectorial Allen-Cahn equation towards multiphase mean curvature
flow for a suitable class of multi- well potentials and for well-prepared initial
data. We even establish a rate of convergence. Our relative energy approach relies
on the concept of gradient-flow calibration for branching singularities in multiphase
mean curvature flow and thus enables us to overcome the limitations of other approaches.
To the best of the author’s knowledge, our result is the first quantitative and
unconditional one available in the literature for the vectorial/multiphase setting.\r\nThis
thesis also contains a first study of weak-strong stability for planar multiphase
mean curvature flow beyond the singularity resulting from a topology change. Previous
weak-strong results are indeed limited to time horizons before the first topology
change of the strong solution. We consider circular topology changes and we prove
weak-strong stability for BV solutions to planar multiphase mean curvature flow
beyond the associated singular times by dynamically adapting the strong solutions
to the weak one by means of a space-time shift.\r\nIn the context of interface
evolution problems, our proofs for the main results of this thesis are based on
the relative energy technique, relying on novel suitable notions of relative energy
functionals, which in particular measure the interface error. Our statements follow
from the resulting stability estimates for the relative energy associated to the
problem.\r\nAt last, we introduce a variational approach to the study of nonlinear
evolution problems. This approach hinges on the minimization of a parameter dependent
family of convex functionals over entire trajectories, known as Weighted Inertia-Dissipation-Energy
(WIDE) functionals. We consider a class of doubly nonlinear wave equations and
establish the convergence, up to subsequences, of the associated WIDE minimizers
to a solution of the target problem as the parameter goes to zero."

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: Endomembrane 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: 'Many insects carry an ancient X chromosome—the Drosophila Muller element
F—that likely predates their origin. Interestingly, the X has undergone turnover
in multiple fly species (Diptera) after being conserved for more than 450 My.
The long evolutionary distance between Diptera and other sequenced insect clades
makes it difficult to infer what could have contributed to this sudden increase
in rate of turnover. Here, we produce the first genome and transcriptome of scorpionflies
(genus Panorpa), an insect belonging to a long overlooked sister-order to Diptera:
Mecoptera. Combining our genome assembly with genomic short-read data, we obtain
genome coverage and identify X-linked super-scaffolds. We further perform a gene
homology analysis between the Panorpa X and a closely related Diptera species,
and we assess the conservation of the Panorpa X-linked gene content with that
of more distantly related insect species. We explored the structure of the Panorpa
X by determining its repeat content, GC content, and nucleotide diversity. Finally,
we used RNAseq data to detect the presence of dosage compensation in somatic tissues,
as well as to explore gene expression tissue-specificity, and sex-bias in gene
expression. We find high conservation of gene content between the mecopteran X
and the dipteran Muller F element, as well as several shared biological features,
such as the presence of dosage compensation and a low amount of genetic diversity,
consistent with a low recombination rate. However, the 2 homologous X chromosomes
differ strikingly in their size and number of genes they carry. Our results therefore
support a common ancestry of the mecopteran and ancestral dipteran X chromosomes,
and suggest that Muller element F shrank in size and gene content after the split
of Diptera and Mecoptera, which may have contributed to its turnover in dipteran
insects.'

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: 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: 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: 'For self-incompatibility (SI) to be stable in a population, theory predicts
that sufficient inbreeding depression (ID) is required: the fitness of offspring
from self-mated individuals must be low enough to prevent the spread of self-compatibility
(SC). Reviews of natural plant populations have supported this theory, with SI
species generally showing high levels of ID. However, there is thought to be an
under-sampling of self-incompatible taxa in the current literature. In this thesis,
I study inbreeding depression in the SI plant species Antirrhinum majus using
both greenhouse crosses and a large collected field dataset. Additionally, the
gametophytic S-locus of A. majus is highly heterozygous and polymorphic, thus
making assembly and discovery of S-alleles very difficult. Here, 206 new alleles
of the male component SLFs are presented, along with a phylogeny showing the high
conservation with alleles from another Antirrhinum species. Lastly, selected sites
within the protein structure of SLFs are investigated, with one site in particular
highlighted as potentially being involved in the SI recognition mechanism.'

text: Two assumptions commonly applied in convection schemes—the diagnostic and
quasi-equilibrium assumptions—imply that convective activity (e.g., convective
precipitation) is controlled only by the large-scale (macrostate) environment
at the time. In contrast, numerical experiments indicate a “memory” or dependence
of convection also on its own previous activity whereby subgrid-scale (microstate)
structures boost but are also boosted by convection. In this study we investigated
this memory by comparing single-column model behavior in two idealized tests previously
executed by a cloud-resolving model (CRM). Conventional convection schemes that
employ the diagnostic assumption fail to reproduce the CRM behavior. The memory-capable
org and Laboratoire de Météorologie Dynamique Zoom cold pool schemes partially
capture the behavior, but fail to fully exhibit the strong reinforcing feedbacks
implied by the CRM. Analysis of this failure suggests that it is because the CRM
supports a linear (or superlinear) dependence of the subgrid structure growth
rate on the precipitation rate, while the org scheme assumes a sublinear dependence.
Among varying versions of the org scheme, the growth rate of the org variable
representing subgrid structure is strongly associated with memory strength. These
results demonstrate the importance of parameterizing convective memory, and the
ability of idealized tests to reveal shortcomings of convection schemes and constrain
model structural assumptions.

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: "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."
