text: Discrete Morse theory has recently lead to new developments in the theory
of random geometric complexes. This article surveys the methods and results obtained
with this new approach, and discusses some of its shortcomings. It uses simulations
to illustrate the results and to form conjectures, getting numerical estimates
for combinatorial, topological, and geometric properties of weighted and unweighted
Delaunay mosaics, their dual Voronoi tessellations, and the Alpha and Wrap complexes
contained in the mosaics.

text: Directional transport of the phytohormone auxin is a versatile, plant-specific
mechanism regulating many aspects of plant development. The recently identified
plant hormones, strigolactones (SLs), are implicated in many plant traits; among
others, they modify the phenotypic output of PIN-FORMED (PIN) auxin transporters
for fine-tuning of growth and developmental responses. Here, we show in pea and
Arabidopsis that SLs target processes dependent on the canalization of auxin flow,
which involves auxin feedback on PIN subcellular distribution. D14 receptor- and
MAX2 F-box-mediated SL signaling inhibits the formation of auxin-conducting channels
after wounding or from artificial auxin sources, during vasculature de novo formation
and regeneration. At the cellular level, SLs interfere with auxin effects on PIN
polar targeting, constitutive PIN trafficking as well as clathrin-mediated endocytosis.
Our results identify a non-transcriptional mechanism of SL action, uncoupling
auxin feedback on PIN polarity and trafficking, thereby regulating vascular tissue
formation and regeneration.

text: 'Clathrin-mediated endocytosis (CME) is a crucial cellular process implicated
in many aspects of plant growth, development, intra- and inter-cellular signaling,
nutrient uptake and pathogen defense. Despite these significant roles, little
is known about the precise molecular details of how it functions in planta. In
order to facilitate the direct quantitative study of plant CME, here we review
current routinely used methods and present refined, standardized quantitative
imaging protocols which allow the detailed characterization of CME at multiple
scales in plant tissues. These include: (i) an efficient electron microscopy protocol
for the imaging of Arabidopsis CME vesicles in situ, thus providing a method for
the detailed characterization of the ultra-structure of clathrin-coated vesicles;
(ii) a detailed protocol and analysis for quantitative live-cell fluorescence
microscopy to precisely examine the temporal interplay of endocytosis components
during single CME events; (iii) a semi-automated analysis to allow the quantitative
characterization of global internalization of cargos in whole plant tissues; and
(iv) an overview and validation of useful genetic and pharmacological tools to
interrogate the molecular mechanisms and function of CME in intact plant samples.'

text: Cell production and differentiation for the acquisition of specific functions
are key features of living systems. The dynamic network of cellular microtubules
provides the necessary platform to accommodate processes associated with the transition
of cells through the individual phases of cytogenesis. Here, we show that the
plant hormone cytokinin fine‐tunes the activity of the microtubular cytoskeleton
during cell differentiation and counteracts microtubular rearrangements driven
by the hormone auxin. The endogenous upward gradient of cytokinin activity along
the longitudinal growth axis in Arabidopsis thaliana roots correlates with robust
rearrangements of the microtubule cytoskeleton in epidermal cells progressing
from the proliferative to the differentiation stage. Controlled increases in cytokinin
activity result in premature re‐organization of the microtubule network from transversal
to an oblique disposition in cells prior to their differentiation, whereas attenuated
hormone perception delays cytoskeleton conversion into a configuration typical
for differentiated cells. Intriguingly, cytokinin can interfere with microtubules
also in animal cells, such as leukocytes, suggesting that a cytokinin‐sensitive
control pathway for the microtubular cytoskeleton may be at least partially conserved
between plant and animal cells.

text: "In the thesis we focus on the interplay of the biophysics and evolution of
gene regulation. We start by addressing how the type of prokaryotic gene regulation
– activation and repression – affects spurious binding to DNA, also known as\r\ntranscriptional
crosstalk. We propose that regulatory interference caused by excess regulatory
proteins in the dense cellular medium – global crosstalk – could be a factor in
determining which type of gene regulatory network is evolutionarily preferred.
Next,we use a normative approach in eukaryotic gene regulation to describe minimal\r\nnon-equilibrium
enhancer models that optimize so-called regulatory phenotypes. We find a class
of models that differ from standard thermodynamic equilibrium models by a single
parameter that notably increases the regulatory performance. Next chapter addresses
the question of genotype-phenotype-fitness maps of higher dimensional phenotypes.
We show that our biophysically realistic approach allows us to understand how
the mechanisms of promoter function constrain genotypephenotype maps, and how
they affect the evolutionary trajectories of promoters.\r\nIn the last chapter
we ask whether the intrinsic instability of gene duplication and amplification
provides a generic alternative to canonical gene regulation. Using mathematical
modeling, we show that amplifications can tune gene expression in many environments,
including those where transcription factor-based schemes are\r\nhard to evolve
or maintain. "

text: 'We present solutions to several problems originating from geometry and discrete
mathematics: existence of equipartitions, maps without Tverberg multiple points,
and inscribing quadrilaterals. Equivariant obstruction theory is the natural topological
approach to these type of questions. However, for the specific problems we consider
it had yielded only partial or no results. We get our results by complementing
equivariant obstruction theory with other techniques from topology and geometry.'

text: In mammalian genomes, a subset of genes is regulated by genomic imprinting,
resulting in silencing of one parental allele. Imprinting is essential for cerebral
cortex development, but prevalence and functional impact in individual cells is
unclear. Here, we determined allelic expression in cortical cell types and established
a quantitative platform to interrogate imprinting in single cells. We created
cells with uniparental chromosome disomy (UPD) containing two copies of either
the maternal or the paternal chromosome; hence, imprinted genes will be 2-fold
overexpressed or not expressed. By genetic labeling of UPD, we determined cellular
phenotypes and transcriptional responses to deregulated imprinted gene expression
at unprecedented single-cell resolution. We discovered an unexpected degree of
cell-type specificity and a novel function of imprinting in the regulation of
cortical astrocyte survival. More generally, our results suggest functional relevance
of imprinted gene expression in glial astrocyte lineage and thus for generating
cortical cell-type diversity.

text: Fejes Tóth [3] studied approximations of smooth surfaces in three-space by
piecewise flat triangular meshes with a given number of vertices on the surface
that are optimal with respect to Hausdorff distance. He proves that this Hausdorff
distance decreases inversely proportional with the number of vertices of the approximating
mesh if the surface is convex. He also claims that this Hausdorff distance is
inversely proportional to the square of the number of vertices for a specific
non-convex surface, namely a one-sheeted hyperboloid of revolution bounded by
two congruent circles. We refute this claim, and show that the asymptotic behavior
of the Hausdorff distance is linear, that is the same as for convex surfaces.

text: The evolution of strong reproductive isolation (RI) is fundamental to the
origins and maintenance of biological diversity, especially in situations where
geographical distributions of taxa broadly overlap. But what is the history behind
strong barriers currently acting in sympatry? Using whole-genome sequencing and
single nucleotide polymorphism genotyping, we inferred (i) the evolutionary relationships,
(ii) the strength of RI, and (iii) the demographic history of divergence between
two broadly sympatric taxa of intertidal snail. Despite being cryptic, based on
external morphology, Littorina arcana and Littorina saxatilis differ in their
mode of female reproduction (egg-laying versus brooding), which may generate a
strong post-zygotic barrier. We show that egg-laying and brooding snails are closely
related, but genetically distinct. Genotyping of 3092 snails from three locations
failed to recover any recent hybrid or backcrossed individuals, confirming that
RI is strong. There was, however, evidence for a very low level of asymmetrical
introgression, suggesting that isolation remains incomplete. The presence of strong,
asymmetrical RI was further supported by demographic analysis of these populations.
Although the taxa are currently broadly sympatric, demographic modelling suggests
that they initially diverged during a short period of geographical separation
involving very low gene flow. Our study suggests that some geographical separation
may kick-start the evolution of strong RI, facilitating subsequent coexistence
of taxa in sympatry. The strength of RI needed to achieve sympatry and the subsequent
effect of sympatry on RI remain open questions.

text: Speciation, that is, the evolution of reproductive barriers eventually leading
to complete isolation, is a crucial process generating biodiversity. Recent work
has contributed much to our understanding of how reproductive barriers begin to
evolve, and how they are maintained in the face of gene flow. However, little
is known about the transition from partial to strong reproductive isolation (RI)
and the completion of speciation. We argue that the evolution of strong RI is
likely to involve different processes, or new interactions among processes, compared
with the evolution of the first reproductive barriers. Transition to strong RI
may be brought about by changing external conditions, for example, following secondary
contact. However, the increasing levels of RI themselves create opportunities
for new barriers to evolve and, and interaction or coupling among barriers. These
changing processes may depend on genomic architecture and leave detectable signals
in the genome. We outline outstanding questions and suggest more theoretical and
empirical work, considering both patterns and processes associated with strong
RI, is needed to understand how speciation is completed.

For\r\nCS2 and I2, they are the first experimental results reported. The alignment
dynamics calculated from the\r\ngas-phase rotational Schrödinger equation, using

text: "Numerous methods have been proposed for probabilistic generative modelling
of\r\n3D objects. However, none of these is able to produce textured objects,
which\r\nrenders them of limited use for practical tasks. In this work, we present
the\r\nfirst generative model of textured 3D meshes. Training such a model would\r\ntraditionally
require a large dataset of textured meshes, but unfortunately,\r\nexisting datasets
of meshes lack detailed textures. We instead propose a new\r\ntraining methodology
that allows learning from collections of 2D images without\r\nany 3D information.
To do so, we train our model to explain a distribution of\r\nimages by modelling
each image as a 3D foreground object placed in front of a\r\n2D background. Thus,
it learns to generate meshes that when rendered, produce\r\nimages similar to
those in its training set.\r\n A well-known problem when generating meshes with
deep networks is the\r\nemergence of self-intersections, which are problematic
for many use-cases. As a\r\nsecond contribution we therefore introduce a new generation
process for 3D\r\nmeshes that guarantees no self-intersections arise, based on
the physical\r\nintuition that faces should push one another out of the way as
they move.\r\n We conduct extensive experiments on our approach, reporting quantitative
and\r\nqualitative results on both synthetic data and natural images. These show
our\r\nmethod successfully learns to generate plausible and diverse textured 3D\r\nsamples
for five challenging object classes."

text: "A natural approach to generative modeling of videos is to represent them
as a composition of moving objects. Recent works model a set of 2D sprites over
a slowly-varying background, but without considering the underlying 3D scene that\r\ngives
rise to them. We instead propose to model a video as the view seen while moving
through a scene with multiple 3D objects and a 3D background. Our model is trained
from monocular videos without any supervision, yet learns to\r\ngenerate coherent
3D scenes containing several moving objects. We conduct detailed experiments on
two datasets, going beyond the visual complexity supported by state-of-the-art
generative approaches. We evaluate our method on\r\ndepth-prediction and 3D object
detection---tasks which cannot be addressed by those earlier works---and show
it out-performs them even on 2D instance segmentation and tracking."

text: 'Fixed-point arithmetic is a popular alternative to floating-point arithmetic
on embedded systems. Existing work on the verification of fixed-point programs
relies on custom formalizations of fixed-point arithmetic, which makes it hard
to compare the described techniques or reuse the implementations. In this paper,
we address this issue by proposing and formalizing an SMT theory of fixed-point
arithmetic. We present an intuitive yet comprehensive syntax of the fixed-point
theory, and provide formal semantics for it based on rational arithmetic. We also
describe two decision procedures for this theory: one based on the theory of bit-vectors
and the other on the theory of reals. We implement the two decision procedures,
and evaluate our implementations using existing mature SMT solvers on a benchmark
suite we created. Finally, we perform a case study of using the theory we propose
to verify properties of quantized neural networks.'

text: We investigate a mechanism to transiently stabilize topological phenomena
in long-lived quasi-steady states of isolated quantum many-body systems driven
at low frequencies. We obtain an analytical bound for the lifetime of the quasi-steady
states which is exponentially large in the inverse driving frequency. Within this
lifetime, the quasi-steady state is characterized by maximum entropy subject to
the constraint of fixed number of particles in the system's Floquet-Bloch bands.
In such a state, all the non-universal properties of these bands are washed out,
hence only the topological properties persist.

text: Using inelastic cotunneling spectroscopy we observe a zero field splitting
within the spin triplet manifold of Ge hut wire quantum dots. The states with
spin ±1 in the confinement direction are energetically favored by up to 55 μeV
compared to the spin 0 triplet state because of the strong spin–orbit coupling.
The reported effect should be observable in a broad class of strongly confined
hole quantum-dot systems and might need to be considered when operating hole spin
qubits.

text: Understanding to what extent stem cell potential is a cell-intrinsic property
or an emergent behavior coming from global tissue dynamics and geometry is a key
outstanding question of systems and stem cell biology. Here, we propose a theory
of stem cell dynamics as a stochastic competition for access to a spatially localized
niche, giving rise to a stochastic conveyor-belt model. Cell divisions produce
a steady cellular stream which advects cells away from the niche, while random
rearrangements enable cells away from the niche to be favorably repositioned.
Importantly, even when assuming that all cells in a tissue are molecularly equivalent,
we predict a common (“universal”) functional dependence of the long-term clonal
survival probability on distance from the niche, as well as the emergence of a
well-defined number of functional stem cells, dependent only on the rate of random
movements vs. mitosis-driven advection. We test the predictions of this theory
on datasets of pubertal mammary gland tips and embryonic kidney tips, as well
as homeostatic intestinal crypts. Importantly, we find good agreement for the
predicted functional dependency of the competition as a function of position,
and thus functional stem cell number in each organ. This argues for a key role
of positional fluctuations in dictating stem cell number and dynamics, and we
discuss the applicability of this theory to other settings.
