text: Since the commercialization of brine shrimp (genus Artemia) in the 1950s,
this lineage, and in particular the model species Artemia franciscana, has been
the subject of extensive research. However, our understanding of the genetic mechanisms
underlying various aspects of their reproductive biology, including sex determination,
are still lacking. This is partly due to the scarcity of genomic resources for
Artemia species and crustaceans in general. Here, we present a chromosome-level
genome assembly of Artemia franciscana (Kellogg 1906), from the Great Salt Lake,
USA. The genome is 1GB, and the majority of the genome (81%) is scaffolded into
21 linkage groups using a previously published high-density linkage map. We performed
coverage and FST analyses using male and female genomic and transcriptomic reads
to quantify the extent of differentiation between the Z and W chromosomes. Additionally,
we quantified the expression levels in male and female heads and gonads and found
further evidence for dosage compensation in this species.

text: "In nature, different species find their niche in a range of environments,
each with its unique characteristics. While some thrive in uniform (homogeneous)
landscapes where environmental conditions stay relatively consistent across space,
others traverse the complexities of spatially heterogeneous terrains. Comprehending
how species are distributed and how they interact within these landscapes holds
the key to gaining insights into their evolutionary dynamics while also informing
conservation and management strategies.\r\n\r\nFor species inhabiting heterogeneous
landscapes, when the rate of dispersal is low compared to spatial fluctuations
in selection pressure, localized adaptations may emerge. Such adaptation in response
to varying selection strengths plays an important role in the persistence of populations
in our rapidly changing world. Hence, species in nature are continuously in a
struggle to adapt to local environmental conditions, to ensure their continued
survival. Natural populations can often adapt in time scales short enough for
evolutionary changes to influence ecological dynamics and vice versa, thereby
creating a feedback between evolution and demography. The analysis of this feedback
and the relative contributions of gene flow, demography, drift, and natural selection
to genetic variation and differentiation has remained a recurring theme in evolutionary
biology. Nevertheless, the effective role of these forces in maintaining variation
and shaping patterns of diversity is not fully understood. Even in homogeneous
environments devoid of local adaptations, such understanding remains elusive.
Understanding this feedback is crucial, for example in determining the conditions
under which extinction risk can be mitigated in peripheral populations subject
to deleterious mutation accumulation at the edges of species’ ranges\r\nas well
as in highly fragmented populations.\r\n\r\nIn this thesis we explore both uniform
and spatially heterogeneous metapopulations, investigating and providing theoretical
insights into the dynamics of local adaptation in the latter and examining the
dynamics of load and extinction as well as the impact of joint ecological and
evolutionary (eco-evolutionary) dynamics in the former. The thesis is divided
into 5 chapters.\r\n\r\nChapter 1 provides a general introduction into the subject
matter, clarifying concepts and ideas used throughout the thesis. In chapter 2,
we explore how fast a species distributed across a heterogeneous landscape adapts
to changing conditions marked by alterations in carrying capacity, selection pressure,
and migration rate.\r\n\r\nIn chapter 3, we investigate how migration selection
and drift influences adaptation and the maintenance of variation in a metapopulation
with three habitats, an extension of previous models of adaptation in two habitats.
We further develop analytical approximations for the critical threshold required
for polymorphism to persist.\r\n\r\nThe focus of chapter 4 of the thesis is on
understanding the interplay between ecology and evolution as coupled processes.
We investigate how eco-evolutionary feedback between migration, selection, drift,
and demography influences eco-evolutionary outcomes in marginal populations subject
to deleterious mutation accumulation. Using simulations as well as theoretical
approximations of the coupled dynamics of population size and allele frequency,
we analyze how gene flow from a large mainland source influences genetic load
and population size on an island (i.e., in a marginal population) under genetically
realistic assumptions. Analyses of this sort are important because small isolated
populations, are repeatedly affected by complex interactions between ecological
and evolutionary processes, which can lead to their death. Understanding these
interactions can therefore provide an insight into the conditions under which
extinction risk can be mitigated in peripheral populations thus, contributing
to conservation and restoration efforts.\r\n\r\nChapter 5 extends the analysis
in chapter 4 to consider the dynamics of load (due to deleterious mutation accumulation)
and extinction risk in a metapopulation. We explore the role of gene flow, selection,
and dominance on load and extinction risk and further pinpoint critical thresholds
required for metapopulation persistence.\r\n\r\nOverall this research contributes
to our understanding of ecological and evolutionary mechanisms that shape species’
persistence in fragmented landscapes, a crucial foundation for successful conservation
efforts and biodiversity management."

text: 'For a set of points in Rd, the Euclidean k-means problems consists of finding
k centers such that the sum of distances squared from each data point to its closest
center is minimized. Coresets are one the main tools developed recently to solve
this problem in a big data context. They allow to compress the initial dataset
while preserving its structure: running any algorithm on the coreset provides
a guarantee almost equivalent to running it on the full data. In this work, we
study coresets in a fully-dynamic setting: points are added and deleted with the
goal to efficiently maintain a coreset with which a k-means solution can be computed.
Based on an algorithm from Henzinger and Kale [ESA''20], we present an efficient
and practical implementation of a fully dynamic coreset algorithm, that improves
the running time by up to a factor of 20 compared to our non-optimized implementation
of the algorithm by Henzinger and Kale, without sacrificing more than 7% on the
quality of the k-means solution.'

text: "Mosaic analysis with double markers (MADM) technology enables the sparse
labeling of genetically defined neurons. We present a protocol for time-lapse
imaging of cortical projection neuron migration in mice using MADM. We describe
steps for the isolation, culturing, and 4D imaging of neuronal dynamics in MADM-labeled
brain tissue. While this protocol is compatible with other single-cell labeling
methods, the MADM approach provides a genetic platform for the functional assessment
of cell-autonomous candidate gene function and the relative contribution of non-cell-autonomous
effects.\r\n\r\nFor complete details on the use and execution of this protocol,

text: Metazoan development relies on the formation and remodeling of cell-cell contacts.
Dynamic reorganization of adhesion receptors and the actomyosin cell cortex in
space and time plays a central role in cell-cell contact formation and maturation.
Nevertheless, how this process is mechanistically achieved when new contacts are
formed remains unclear. Here, by building a biomimetic assay composed of progenitor
cells adhering to supported lipid bilayers functionalized with E-cadherin ectodomains,
we show that cortical F-actin flows, driven by the depletion of myosin-2 at the
cell contact center, mediate the dynamic reorganization of adhesion receptors
and cell cortex at the contact. E-cadherin-dependent downregulation of the small
GTPase RhoA at the forming contact leads to both a depletion of myosin-2 and a
decrease of F-actin at the contact center. At the contact rim, in contrast, myosin-2
becomes enriched by the retraction of bleb-like protrusions, resulting in a cortical
tension gradient from the contact rim to its center. This tension gradient, in
turn, triggers centrifugal F-actin flows, leading to further accumulation of F-actin
at the contact rim and the progressive redistribution of E-cadherin from the contact
center to the rim. Eventually, this combination of actomyosin downregulation and
flows at the contact determines the characteristic molecular organization, with
E-cadherin and F-actin accumulating at the contact rim, where they are needed
to mechanically link the contractile cortices of the adhering cells.

text: We study a random matching problem on closed compact 2 -dimensional Riemannian
manifolds (with respect to the squared Riemannian distance), with samples of random
points whose common law is absolutely continuous with respect to the volume measure
with strictly positive and bounded density. We show that given two sequences of
numbers n and m=m(n) of points, asymptotically equivalent as n goes to infinity,
the optimal transport plan between the two empirical measures μn and νm is
quantitatively well-approximated by (Id,exp(∇hn))#μn where hn solves a linear
elliptic PDE obtained by a regularized first-order linearization of the Monge-Ampère
equation. This is obtained in the case of samples of correlated random points
for which a stretched exponential decay of the α -mixing coefficient holds and
for a class of discrete-time Markov chains having a unique absolutely continuous
invariant measure with respect to the volume measure.

text: Frequency-stable lasers form the back bone of precision measurements in science
and technology. Such lasers typically attain their stability through frequency
locking to reference cavities. State-of-the-art locking performances to date had
been achieved using frequency modulation based methods, complemented with active
drift cancellation systems. We demonstrate an all passive, modulation-free laser-cavity
locking technique (squash locking) that utilizes changes in spatial beam ellipticity
for error signal generation, and a coherent polarization post-selection for noise
resilience. By comparing two identically built proof-of-principle systems, we
show a frequency locking instability of 5×10−7 relative to
the cavity linewidth at 10 s averaging. The results surpass the demonstrated performances
of methods engineered over the last five decades, potentially enabling an advancement
in the precision control of lasers, while creating avenues for bridging the performance
gaps between industrial grade lasers with scientific ones due to the afforded
simplicity and scalability.

text: The plant-signaling molecule auxin triggers fast and slow cellular responses
across land plants and algae. The nuclear auxin pathway mediates gene expression
and controls growth and development in land plants, but this pathway is absent
from algal sister groups. Several components of rapid responses have been identified
in Arabidopsis, but it is unknown if these are part of a conserved mechanism.
We recently identified a fast, proteome-wide phosphorylation response to auxin.
Here, we show that this response occurs across 5 land plant and algal species
and converges on a core group of shared targets. We found conserved rapid physiological
responses to auxin in the same species and identified rapidly accelerated fibrosarcoma
(RAF)-like protein kinases as central mediators of auxin-triggered phosphorylation
across species. Genetic analysis connects this kinase to both auxin-triggered
protein phosphorylation and rapid cellular response, thus identifying an ancient
mechanism for fast auxin responses in the green lineage.

text: Production of hydrogen at large scale requires development of non-noble, inexpensive,
and high-performing catalysts for constructing water-splitting devices. Herein,
we report the synthesis of Zn-doped NiO heterostructure (ZnNiO) catalysts at room
temperature via a coprecipitation method followed by drying (at 80 °C, 6 h) and
calcination at an elevated temperature of 400 °C for 5 h under three distinct
conditions, namely, air, N2, and vacuum. The vacuum-synthesized catalyst demonstrates
a low overpotential of 88 mV at −10 mA cm–2 and a small Tafel slope of 73 mV dec–1
suggesting relatively higher charge transfer kinetics for hydrogen evolution reactions
(HER) compared with the specimens synthesized under N2 or O2 atmosphere. It also
demonstrates an oxygen evolution (OER) overpotential of 260 mV at 10 mA cm–2 with
a low Tafel slope of 63 mV dec–1. In a full-cell water-splitting device, the vacuum-synthesized
ZnNiO heterostructure demonstrates a cell voltage of 1.94 V at 50 mA cm–2 and
shows remarkable stability over 24 h at a high current density of 100 mA cm–2.
It is also demonstrated in this study that Zn-doping, surface, and interface engineering
in transition-metal oxides play a crucial role in efficient electrocatalytic water
splitting. Also, the results obtained from density functional theory (DFT + U
= 0–8 eV), where U is the on-site Coulomb repulsion parameter also known as Hubbard
U, based electronic structure calculations confirm that Zn doping constructively
modifies the electronic structure, in both the valence band and the conduction
band, and found to be suitable in tailoring the carrier’s effective masses of
electrons and holes. The decrease in electron’s effective masses together with
large differences between the effective masses of electrons and holes is noticed,
which is found to be mainly responsible for achieving the best water-splitting
performance from a 9% Zn-doped NiO sample prepared under vacuum.

text: Bacteria divide by binary fission. The protein machine responsible for this
process is the divisome, a transient assembly of more than 30 proteins in and
on the surface of the cytoplasmic membrane. Together, they constrict the cell
envelope and remodel the peptidoglycan layer to eventually split the cell into
two. For Escherichia coli, most molecular players involved in this process have
probably been identified, but obtaining the quantitative information needed for
a mechanistic understanding can often not be achieved from experiments in vivo
alone. Since the discovery of the Z-ring more than 30 years ago, in vitro reconstitution
experiments have been crucial to shed light on molecular processes normally hidden
in the complex environment of the living cell. In this review, we summarize how
rebuilding the divisome from purified components – or at least parts of it - have
been instrumental to obtain the detailed mechanistic understanding of the bacterial
cell division machinery that we have today.

text: De novo heterozygous variants in KCNC2 encoding the voltage-gated potassium
(K+) channel subunit Kv3.2 are a recently described cause of developmental and
epileptic encephalopathy (DEE). A de novo variant in KCNC2 c.374G > A (p.Cys125Tyr)
was identified via exome sequencing in a patient with DEE. Relative to wild-type
Kv3.2, Kv3.2-p.Cys125Tyr induces K+ currents exhibiting a large hyperpolarizing
shift in the voltage dependence of activation, accelerated activation, and delayed
deactivation consistent with a relative stabilization of the open conformation,
along with increased current density. Leveraging the cryogenic electron microscopy
(cryo-EM) structure of Kv3.1, molecular dynamic simulations suggest that a strong
π-π stacking interaction between the variant Tyr125 and Tyr156 in the α-6 helix
of the T1 domain promotes a relative stabilization of the open conformation of
the channel, which underlies the observed gain of function. A multicompartment
computational model of a Kv3-expressing parvalbumin-positive cerebral cortex fast-spiking
γ-aminobutyric acidergic (GABAergic) interneuron (PV-IN) demonstrates how the
Kv3.2-Cys125Tyr variant impairs neuronal excitability and dysregulates inhibition
in cerebral cortex circuits to explain the resulting epilepsy.

text: The coupling between Ca2+ channels and release sensors is a key factor defining
the signaling properties of a synapse. However, the coupling nanotopography at
many synapses remains unknown, and it is unclear how it changes during development.
To address these questions, we examined coupling at the cerebellar inhibitory
basket cell (BC)-Purkinje cell (PC) synapse. Biophysical analysis of transmission
by paired recording and intracellular pipette perfusion revealed that the effects
of exogenous Ca2+ chelators decreased during development, despite constant reliance
of release on P/Q-type Ca2+ channels. Structural analysis by freeze-fracture replica
labeling (FRL) and transmission electron microscopy (EM) indicated that presynaptic
P/Q-type Ca2+ channels formed nanoclusters throughout development, whereas docked
vesicles were only clustered at later developmental stages. Modeling suggested
a developmental transformation from a more random to a more clustered coupling
nanotopography. Thus, presynaptic signaling developmentally approaches a point-to-point
configuration, optimizing speed, reliability, and energy efficiency of synaptic
transmission.

text: We study a linear rotor in a bosonic bath within the angulon formalism. Our
focus is on systems where isotropic or anisotropic impurity-boson interactions
support a shallow bound state. To study the fate of the angulon in the vicinity
of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian.
First, we use it to study attractive, spherically symmetric impurity-boson interactions
for which the linear rotor can be mapped onto a static impurity. The well-known
polaron formalism provides an adequate description in this limit. Second, we consider
anisotropic potentials, and show that the presence of a shallow bound state with
pronounced anisotropic character leads to a many-body instability that washes
out the angulon dynamics.

text: Contraction and flow of the actin cell cortex have emerged as a common principle
by which cells reorganize their cytoplasm and take shape. However, how these cortical
flows interact with adjacent cytoplasmic components, changing their form and localization,
and how this affects cytoplasmic organization and cell shape remains unclear.
Here we show that in ascidian oocytes, the cooperative activities of cortical
actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive
oocyte cytoplasmic reorganization and shape changes following fertilization. We
show that vegetal-directed cortical actomyosin flows, established upon oocyte
fertilization, lead to both the accumulation of cortical actin at the vegetal
pole of the zygote and compression and local buckling of the adjacent elastic
solid-like myoplasm layer due to friction forces generated at their interface.
Once cortical flows have ceased, the multiple myoplasm buckles resolve into one
larger buckle, which again drives the formation of the contraction pole—a protuberance
of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings
reveal a mechanism where cortical actomyosin network flows determine cytoplasmic
reorganization and cell shape by deforming adjacent cytoplasmic components through
friction forces.

text: Elaborate sexual signals are thought to have evolved and be maintained to
serve as honest indicators of signaller quality. One measure of quality is health,
which can be affected by parasite infection. Cnemaspis mysoriensis is a diurnal
gecko that is often infested with ectoparasites in the wild, and males of this
species express visual (coloured gular patches) and chemical (femoral gland secretions)
traits that receivers could assess during social interactions. In this paper,
we tested whether ectoparasites affect individual health, and whether signal quality
is an indicator of ectoparasite levels. In wild lizards, we found that ectoparasite
level was negatively correlated with body condition in both sexes. Moreover, some
characteristics of both visual and chemical traits in males were strongly associated
with ectoparasite levels. Specifically, males with higher ectoparasite levels
had yellow gular patches with lower brightness and chroma, and chemical secretions
with a lower proportion of aromatic compounds. We then determined whether ectoparasite
levels in males influence female behaviour. Using sequential choice trials, wherein
females were provided with either the visual or the chemical signals of wild-caught
males that varied in ectoparasite level, we found that only chemical secretions
evoked an elevated female response towards less parasitised males. Simultaneous
choice trials in which females were exposed to the chemical secretions from males
that varied in parasite level further confirmed a preference for males with lower
parasites loads. Overall, we find that although health (body condition) or ectoparasite
load can be honestly advertised through multiple modalities, the parasite-mediated
female response is exclusively driven by chemical signals.

text: Die Quantenrotation ist ein spannendes Phänomen, das in vielen verschiedenen
Systemen auftritt, von Molekülen und Atomen bis hin zu subatomaren Teilchen wie
Neutronen und Protonen. Durch den Einsatz von starken Laserpulsen ist es möglich,
die mathematisch anspruchsvolle Topologie der Rotation von Molekülen aufzudecken
und topologisch geschützte Zustände zu erzeugen, die unerwartetes Verhalten zeigen.
Diese Entdeckungen könnten Auswirkungen auf die Molekülphysik und physikalische
Chemie haben und die Entwicklung neuer Technologien ermöglichen. Die Verbindung
von Quantenrotation und Topologie stellt ein aufregendes, interdisziplinäres Forschungsfeld
dar und bietet neue Wege zur Kontrolle und Nutzung von quantenmechanischen Phänomenen.

text: The physical conditions giving rise to high escape fractions of ionizing radiation
(LyC fesc) in star-forming galaxies – most likely protagonists of cosmic reionization
– are not yet fully understood. Using the VLT/MUSE observations of ∼1400 Ly α
emitters at 2.9 < z < 6.7, we compare stacked rest-frame UV spectra
of candidates for LyC leakers and non-leakers selected based on their Ly α profiles.
We find that the stacks of potential LyC leakers, i.e. galaxies with narrow, symmetric
Ly α profiles with small peak separation, generally show (i) strong nebular O iii]λ1666,
[Si iii]λ1883, and [C iii]λ1907 +C iii]λ1909 emission, indicating a high-ionization
state of the interstellar medium (ISM); (ii) high equivalent widths of He iiλ1640
(∼1 − 3 Å), suggesting the presence of hard ionizing radiation fields; (iii) Si ii*λ1533
emission, revealing substantial amounts of neutral hydrogen off the line of sight;
(iv) high C ivλλ1548,1550 to [C iii]λ1907 +C iii]λ1909 ratios (C iv/C iii] ≳0.75)
, signalling the presence of low column density channels in the ISM. In contrast,
the stacks with broad, asymmetric Ly α profiles with large peak separation show
weak nebular emission lines, low He iiλ1640 equivalent widths (≲1 Å), and low
C iv/C iii] (≲0.25), implying low-ionization states and high-neutral hydrogen
column densities. Our results suggest that C iv/C iii] might be sensitive to the
physical conditions that govern LyC photon escape, providing a promising tool
for identification of ionizing sources among star-forming galaxies in the epoch
of reionization.

text: We perform a stochastic homogenization analysis for composite materials exhibiting
a random microstructure. Under the assumptions of stationarity and ergodicity,
we characterize the Gamma-limit of a micromagnetic energy functional defined on
magnetizations taking value in the unit sphere and including both symmetric and
antisymmetric exchange contributions. This Gamma-limit corresponds to a micromagnetic
energy functional with homogeneous coefficients. We provide explicit formulas
for the effective magnetic properties of the composite material in terms of homogenization
correctors. Additionally, the variational analysis of the two exchange energy
terms is performed in the more general setting of functionals defined on manifold-valued
maps with Sobolev regularity, in the case in which the target manifold is a bounded,
orientable smooth surface with tubular neighborhood of uniform thickness. Eventually,
we present an explicit characterization of minimizers of the effective exchange
in the case of magnetic multilayers, providing quantitative evidence of Dzyaloshinskii’s
predictions on the emergence of helical structures in composite ferromagnetic
materials with stochastic microstructure.

text: The near-surface boundary layer can mediate the response of mountain glaciers
to external climate, cooling the overlying air and promoting a density-driven
glacier wind. The fundamental processes are conceptually well understood, though
the magnitudes of cooling and presence of glacier winds are poorly quantified
in space and time, increasing the forcing uncertainty for melt models. We utilize
a new data set of on-glacier meteorological measurements on three neighboring
glaciers in the Swiss Alps to explore their distinct response to regional climate
under the extreme 2022 summer. We find that synoptic wind origins and local terrain
modifications, not only glacier size, play an important role in the ability of
a glacier to cool the near-surface air. Warm air intrusions from valley or synoptically-driven
winds onto the glacier can occur between ∼19% and 64% of the time and contribute
between 3% and 81% of the total sensible heat flux to the surface during warm
afternoon hours, depending on the fetch of the glacier flowline and its susceptibility
to boundary layer erosion. In the context of extreme summer warmth, indicative
of future conditions, the boundary layer cooling (up to 6.5°C cooler than its
surroundings) and resultant katabatic wind flow are highly heterogeneous between
the study glaciers, highlighting the complex and likely non-linear response of
glaciers to an uncertain future.
