text: We solve a problem of Dujmović and Wood (2007) by showing that a complete
convex geometric graph on n vertices cannot be decomposed into fewer than n-1
star-forests, each consisting of noncrossing edges. This bound is clearly tight.
We also discuss similar questions for abstract graphs.

text: 'The development, evolution, and function of the vertebrate central nervous
system (CNS) can be best studied using diverse model organisms. Amphibians, with
their unique phylogenetic position at the transition between aquatic and terrestrial
lifestyles, are valuable for understanding the origin and evolution of the tetrapod
brain and spinal cord. Their metamorphic developmental transitions and unique
regenerative abilities also facilitate the discovery of mechanisms for neural
circuit remodeling and replacement. The genetic toolkit for amphibians, however,
remains limited, with only a few species having sequenced genomes and a small
number of transgenic lines available. In mammals, recombinant adeno-associated
viral vectors (AAVs) have become a powerful alternative to genome modification
for visualizing and perturbing the nervous system. AAVs are DNA viruses that enable
neuronal transduction in both developing and adult animals with low toxicity and
spatial, temporal, and cell-type specificity. However, AAVs have never been shown
to transduce amphibian cells efficiently. To bridge this gap, we established a
simple, scalable, and robust strategy to screen AAV serotypes in three distantly-related
amphibian species: the frogs Xenopus laevis and Pelophylax bedriagae, and the
salamander Pleurodeles waltl, in both developing larval tadpoles and post-metamorphic
animals. For each species, we successfully identified at least two AAV serotypes
capable of infecting the CNS; however, no pan-amphibian serotype was identified,
indicating rapid evolution of AAV tropism. In addition, we developed an AAV-based
strategy that targets isochronic cohorts of developing neurons – a critical tool
for parsing neural circuit assembly. Finally, to enable visualization and manipulation
of neural circuits, we identified AAV variants for retrograde tracing of neuronal
projections in adult animals. Our findings expand the toolkit for amphibians to
include AAVs, establish a generalizable workflow for AAV screening in non-canonical
research organisms, generate testable hypotheses for the evolution of AAV tropism,
and lay the foundation for modern cross-species comparisons of vertebrate CNS
development, function, and evolution. '

text: The epitaxial growth of a strained Ge layer, which is a promising candidate
for the channel material of a hole spin qubit, has been demonstrated on 300 mm
Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB)
layers. The assessment of the layer and the interface qualities for a buried strained
Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping
confirmed that the reduction of the growth temperature enables the 2-dimensional
growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless,
dislocations at the top and/or bottom interface of the Ge layer were observed
by means of electron channeling contrast imaging, suggesting the importance of
the careful dislocation assessment. The interface abruptness does not depend on
the selection of the precursor gases, but it is strongly influenced by the growth
temperature which affects the coverage of the surface H-passivation. The mobility
of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010
/cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the
heterostructure thanks to the high Si0.3Ge0.7 SRB quality.

text: "This thesis consists of four distinct pieces of work within theoretical biology,
with two themes in common: the concept of optimization in biological systems,
and the use of information-theoretic tools to quantify biological stochasticity
and statistical uncertainty.\r\nChapter 2 develops a statistical framework for
studying biological systems which we believe to be optimized for a particular
utility function, such as retinal neurons conveying information about visual stimuli.
We formalize such beliefs as maximum-entropy Bayesian priors, constrained by the
expected utility. We explore how such priors aid inference of system parameters
with limited data and enable optimality hypothesis testing: is the utility higher
than by chance?\r\nChapter 3 examines the ultimate biological optimization process:
evolution by natural selection. As some individuals survive and reproduce more
successfully than others, populations evolve towards fitter genotypes and phenotypes.
We formalize this as accumulation of genetic information, and use population genetics
theory to study how much such information can be accumulated per generation and
maintained in the face of random mutation and genetic drift. We identify the population
size and fitness variance as the key quantities that control information accumulation
and maintenance.\r\nChapter 4 reuses the concept of genetic information from Chapter
3, but from a different perspective: we ask how much genetic information organisms
actually need, in particular in the context of gene regulation. For example, how
much information is needed to bind transcription factors at correct locations
within the genome? Population genetics provides us with a refined answer: with
an increasing population size, populations achieve higher fitness by maintaining
more genetic information. Moreover, regulatory parameters experience selection
pressure to optimize the fitness-information trade-off, i.e. minimize the information
needed for a given fitness. This provides an evolutionary derivation of the optimization
priors introduced in Chapter 2.\r\nChapter 5 proves an upper bound on mutual information
between a signal and a communication channel output (such as neural activity).
Mutual information is an important utility measure for biological systems, but
its practical use can be difficult due to the large dimensionality of many biological
channels. Sometimes, a lower bound on mutual information is computed by replacing
the high-dimensional channel outputs with decodes (signal estimates). Our result
provides a corresponding upper bound, provided that the decodes are the maximum
posterior estimates of the signal."

text: Electrostatic correlations between ions dissolved in water are known to impact
their transport properties in numerous ways, from conductivity to ion selectivity.
The effects of these correlations on the solvent itself remain, however, much
less clear. In particular, the addition of salt has been consistently reported
to affect the solution’s viscosity, but most modeling attempts fail to reproduce
experimental data even at moderate salt concentrations. Here, we use an approach
based on stochastic density functional theory, which accurately captures charge
fluctuations and correlations. We derive a simple analytical expression for the
viscosity correction in concentrated electrolytes, by directly linking it to the
liquid’s structure factor. Our prediction compares quantitatively to experimental
data at all temperatures and all salt concentrations up to the saturation limit.
This universal link between the microscopic structure and viscosity allows us
to shed light on the nanoscale dynamics of water and ions under highly concentrated
and correlated conditions.

text: We consider quadratic forms of deterministic matrices A evaluated at the random
eigenvectors of a large N×N GOE or GUE matrix, or equivalently evaluated at the
columns of a Haar-orthogonal or Haar-unitary random matrix. We prove that, as
long as the deterministic matrix has rank much smaller than √N, the distributions
of the extrema of these quadratic forms are asymptotically the same as if the
eigenvectors were independent Gaussians. This reduces the problem to Gaussian
computations, which we carry out in several cases to illustrate our result, finding
Gumbel or Weibull limiting distributions depending on the signature of A. Our
result also naturally applies to the eigenvectors of any invariant ensemble.

text: The GNOM (GN) Guanine nucleotide Exchange Factor for ARF small GTPases (ARF-GEF)
is among the best studied trafficking regulators in plants, playing crucial and
unique developmental roles in patterning and polarity. The current models place
GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at
the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis
(CME). The mechanistic basis of the developmental function of GN, distinct from
the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains
elusive. Insights from this study largely extend the current notions of GN function.
We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures
distinct from clathrin-coated pits, while CME and secretion proceed normally in
gn knockouts. The functional GN mutant variant GNfewerroots,
absent from the GA, suggests that the cell periphery is the major site of GN action
responsible for its developmental function. Following inhibition by Brefeldin
A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting
selective molecular associations en route to the cell periphery. A study of GN-GNL1
chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN
function in a partially redundant manner. Together, this study offers significant
steps toward the elucidation of the mechanism underlying unique cellular and development
functions of GNOM.

text: Coupling of orbital motion to a spin degree of freedom gives rise to various
transport phenomena in quantum systems that are beyond the standard paradigms
of classical physics. Here, we discuss features of spin-orbit dynamics that can
be visualized using a classical model with two coupled angular degrees of freedom.
Specifically, we demonstrate classical ‘spin’ filtering through our model and
show that the interplay between angular degrees of freedom and dissipation can
lead to asymmetric ‘spin’ transport.

text: Tropical precipitation extremes and their changes with surface warming are
investigated using global storm resolving simulations and high-resolution observations.
The simulations demonstrate that the mesoscale organization of convection, a process
that cannot be physically represented by conventional global climate models, is
important for the variations of tropical daily accumulated precipitation extremes.
In both the simulations and observations, daily precipitation extremes increase
in a more organized state, in association with larger, but less frequent, storms.
Repeating the simulations for a warmer climate results in a robust increase in
monthly-mean daily precipitation extremes. Higher precipitation percentiles have
a greater sensitivity to convective organization, which is predicted to increase
with warming. Without changes in organization, the strongest daily precipitation
extremes over the tropical oceans increase at a rate close to Clausius-Clapeyron
(CC) scaling. Thus, in a future warmer state with increased organization, the
strongest daily precipitation extremes over oceans increase at a faster rate than
CC scaling.

text: Embryogenesis results from the coordinated activities of different signaling
pathways controlling cell fate specification and morphogenesis. In vertebrate
gastrulation, both Nodal and BMP signaling play key roles in germ layer specification
and morphogenesis, yet their interplay to coordinate embryo patterning with morphogenesis
is still insufficiently understood. Here, we took a reductionist approach using
zebrafish embryonic explants to study the coordination of Nodal and BMP signaling
for embryo patterning and morphogenesis. We show that Nodal signaling triggers
explant elongation by inducing mesendodermal progenitors but also suppressing
BMP signaling activity at the site of mesendoderm induction. Consistent with this,
ectopic BMP signaling in the mesendoderm blocks cell alignment and oriented mesendoderm
intercalations, key processes during explant elongation. Translating these ex
vivo observations to the intact embryo showed that, similar to explants, Nodal
signaling suppresses the effect of BMP signaling on cell intercalations in the
dorsal domain, thus allowing robust embryonic axis elongation. These findings
suggest a dual function of Nodal signaling in embryonic axis elongation by both
inducing mesendoderm and suppressing BMP effects in the dorsal portion of the
mesendoderm.

text: Atom-based quantum simulators have had many successes in tackling challenging
quantum many-body problems, owing to the precise and dynamical control that they
provide over the systems' parameters. They are, however, often optimized to address
a specific type of problem. Here, we present the design and implementation of
a 6Li-based quantum gas platform that provides wide-ranging capabilities and is
able to address a variety of quantum many-body problems. Our two-chamber architecture
relies on a robust combination of gray molasses and optical transport from a laser-cooling
chamber to a glass cell with excellent optical access. There, we first create
unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap
and characterize them using in situ thermometry, reaching temperatures below 20
nK. This allows us to enter the deep superfluid regime with samples of extreme
diluteness, where the interparticle spacing is sufficiently large for direct single-atom
imaging. Second, we generate optical lattice potentials with triangular and honeycomb
geometry in which we study diffraction of molecular Bose-Einstein condensates,
and show how going beyond the Kapitza-Dirac regime allows us to unambiguously
distinguish between the two geometries. With the ability to probe quantum many-body
physics in both discrete and continuous space, and its suitability for bulk and
single-atom imaging, our setup represents an important step towards achieving
a wide-scope quantum simulator.

text: We introduce a method to segment the visual field into independently moving
regions, trained with no ground truth or supervision. It consists of an adversarial
conditional encoder-decoder architecture based on Slot Attention, modified to
use the image as context to decode optical flow without attempting to reconstruct
the image itself. In the resulting multi-modal representation, one modality (flow)
feeds the encoder to produce separate latent codes (slots), whereas the other
modality (image) conditions the decoder to generate the first (flow) from the
slots. This design frees the representation from having to encode complex nuisance
variability in the image due to, for instance, illumination and reflectance properties
of the scene. Since customary autoencoding based on minimizing the reconstruction
error does not preclude the entire flow from being encoded into a single slot,
we modify the loss to an adversarial criterion based on Contextual Information
Separation. The resulting min-max optimization fosters the separation of objects
and their assignment to different attention slots, leading to Divided Attention,
or DivA. DivA outperforms recent unsupervised multi-object motion segmentation
methods while tripling run-time speed up to 104FPS and reducing the performance
gap from supervised methods to 12% or less. DivA can handle different numbers
of objects and different image sizes at training and test time, is invariant to
permutation of object labels, and does not require explicit regularization.

text: The phytohormone auxin and its directional transport through tissues play
a fundamental role in development of higher plants. This polar auxin transport
predominantly relies on PIN-FORMED (PIN) auxin exporters. Hence, PIN polarization
is crucial for development, but its evolution during the rise of morphological
complexity in land plants remains unclear. Here, we performed a cross-species
investigation by observing the trafficking and localization of endogenous and
exogenous PINs in two bryophytes, Physcomitrium patens and Marchantia polymorpha,
and in the flowering plant Arabidopsis thaliana. We confirmed that the GFP fusion
did not compromise the auxin export function of all examined PINs by using radioactive
auxin export assay and by observing the phenotypic changes in transgenic bryophytes.
Endogenous PINs polarize to filamentous apices, while exogenous Arabidopsis PINs
distribute symmetrically on the membrane in both bryophytes. In Arabidopsis root
epidermis, bryophytic PINs show no defined polarity. Pharmacological interference
revealed a strong cytoskeleton dependence of bryophytic but not Arabidopsis PIN
polarization. The divergence of PIN polarization and trafficking is also observed
within the bryophyte clade and between tissues of individual species. These results
collectively reveal a divergence of PIN trafficking and polarity mechanisms throughout
land plant evolution and a co-evolution of PIN sequence-based and cell-based polarity
mechanisms.

text: 'In animals, parasitic infections impose significant fitness costs.1,2,3,4,5,6
Infected animals can alter their feeding behavior to resist infection,7,8,9,10,11,12
but parasites can manipulate animal foraging behavior to their own benefits.13,14,15,16
How nutrition influences host-parasite interactions is not well understood, as
studies have mainly focused on the host and less on the parasite.9,12,17,18,19,20,21,22,23
We used the nutritional geometry framework24 to investigate the role of amino
acids (AA) and carbohydrates (C) in a host-parasite system: the Argentine ant,
Linepithema humile, and the entomopathogenic fungus, Metarhizium brunneum. First,
using 18 diets varying in AA:C composition, we established that the fungus performed
best on the high-amino-acid diet 1:4. Second, we found that the fungus reached
this optimal diet when given various diet pairings, revealing its ability to cope
with nutritional challenges. Third, we showed that the optimal fungal diet reduced
the lifespan of healthy ants when compared with a high-carbohydrate diet but had
no effect on infected ants. Fourth, we revealed that infected ant colonies, given
a choice between the optimal fungal diet and a high-carbohydrate diet, chose the
optimal fungal diet, whereas healthy colonies avoided it. Lastly, by disentangling
fungal infection from host immune response, we demonstrated that infected ants
foraged on the optimal fungal diet in response to immune activation and not as
a result of parasite manipulation. Therefore, we revealed that infected ant colonies
chose a diet that is costly for survival in the long term but beneficial in the
short term—a form of collective self-medication.'

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: 'Post-translational histone modifications modulate chromatin activity to affect
gene expression. How chromatin states underlie lineage choice in single cells
is relatively unexplored. We develop sort-assisted single-cell chromatin immunocleavage
(sortChIC) and map active (H3K4me1 and H3K4me3) and repressive (H3K27me3 and H3K9me3)
histone modifications in the mouse bone marrow. During differentiation, hematopoietic
stem and progenitor cells (HSPCs) acquire active chromatin states mediated by
cell-type-specifying transcription factors, which are unique for each lineage.
By contrast, most alterations in repressive marks during differentiation occur
independent of the final cell type. Chromatin trajectory analysis shows that lineage
choice at the chromatin level occurs at the progenitor stage. Joint profiling
of H3K4me1 and H3K9me3 demonstrates that cell types within the myeloid lineage
have distinct active chromatin but share similar myeloid-specific heterochromatin
states. This implies a hierarchical regulation of chromatin during hematopoiesis:
heterochromatin dynamics distinguish differentiation trajectories and lineages,
while euchromatin dynamics reflect cell types within lineages.'

text: The term “haplotype block” is commonly used in the developing field of haplotype-based
inference methods. We argue that the term should be defined based on the structure
of the Ancestral Recombination Graph (ARG), which contains complete information
on the ancestry of a sample. We use simulated examples to demonstrate key features
of the relationship between haplotype blocks and ancestral structure, emphasizing
the stochasticity of the processes that generate them. Even the simplest cases
of neutrality or of a “hard” selective sweep produce a rich structure, often missed
by commonly used statistics. We highlight a number of novel methods for inferring
haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate
how they can be used to define haplotype blocks using an empirical data set. While
the advent of new, computationally efficient methods makes it possible to apply
these concepts broadly, they (and additional new methods) could benefit from adding
features to explore haplotype blocks, as we define them. Understanding and applying
the concept of the haplotype block will be essential to fully exploit long and
linked-read sequencing technologies.

text: Homeostatic balance in the intestinal epithelium relies on a fast cellular
turnover, which is coordinated by an intricate interplay between biochemical signalling,
mechanical forces and organ geometry. We review recent modelling approaches that
have been developed to understand different facets of this remarkable homeostatic
equilibrium. Existing models offer different, albeit complementary, perspectives
on the problem. First, biomechanical models aim to explain the local and global
mechanical stresses driving cell renewal as well as tissue shape maintenance.
Second, compartmental models provide insights into the conditions necessary to
keep a constant flow of cells with well-defined ratios of cell types, and how
perturbations can lead to an unbalance of relative compartment sizes. A third
family of models address, at the cellular level, the nature and regulation of
stem fate choices that are necessary to fuel cellular turnover. We also review
how these different approaches are starting to be integrated together across scales,
to provide quantitative predictions and new conceptual frameworks to think about
the dynamics of cell renewal in complex tissues.

text: Small GTPases play essential roles in the organization of eukaryotic cells.
In recent years, it has become clear that their intracellular functions result
from intricate biochemical networks of the GTPase and their regulators that dynamically
bind to a membrane surface. Due to the inherent complexities of their interactions,
however, revealing the underlying mechanisms of action is often difficult to achieve
from in vivo studies. This review summarizes in vitro reconstitution approaches
developed to obtain a better mechanistic understanding of how small GTPase activities
are regulated in space and time.
