text: We show that any sufficiently (finitely) smooth ℤ₂-symmetric strictly convex
domain sufficiently close to a circle is dynamically spectrally rigid; i.e., all
deformations among domains in the same class that preserve the length of all periodic
orbits of the associated billiard flow must necessarily be isometric deformations.
This gives a partial answer to a question of P. Sarnak.

text: We study the lengths of curves passing through a fixed number of points on
the boundary of a convex shape in the plane. We show that, for any convex shape
K, there exist four points on the boundary of K such that the length of any curve
passing through these points is at least half of the perimeter of K. It is also
shown that the same statement does not remain valid with the additional constraint
that the points are extreme points of K. Moreover, the factor ½ cannot
be achieved with any fixed number of extreme points. We conclude the paper with
a few other inequalities related to the perimeter of a convex shape.

text: "Frequency-independent selection is generally considered as a force that acts
to reduce the genetic variation in evolving populations, yet rigorous arguments
for this idea are scarce. When selection fluctuates in time, it is unclear whether
frequency-independent selection may maintain genetic polymorphism without invoking
additional mechanisms. We show that constant frequency-independent selection with
arbitrary epistasis on a well-mixed haploid population eliminates genetic variation
if we assume linkage equilibrium between alleles. To this end, we introduce the
notion of frequency-independent selection at the level of alleles, which is sufficient
to prove our claim and contains the notion of frequency-independent selection
on haploids. When selection and recombination are weak but of the same order,
there may be strong linkage disequilibrium; numerical calculations show that stable
equilibria are highly unlikely. Using the example of a diallelic two-locus model,
we then demonstrate that frequency-independent selection that fluctuates in time
can maintain stable polymorphism if linkage disequilibrium changes its sign periodically.
We put our findings in the context of results from the existing literature and
point out those scenarios in which the possible role of frequency-independent
selection in maintaining genetic variation remains unclear.\r\n"

text: We develop a probabilistic technique for colorizing grayscale natural images.
In light of the intrinsic uncertainty of this task, the proposed probabilistic
framework has numerous desirable properties. In particular, our model is able
to produce multiple plausible and vivid colorizations for a given grayscale image
and is one of the first colorization models to provide a proper stochastic sampling
scheme. Moreover, our training procedure is supported by a rigorous theoretical
framework that does not require any ad hoc heuristics and allows for efficient
modeling and learning of the joint pixel color distribution.We demonstrate strong
quantitative and qualitative experimental results on the CIFAR-10 dataset and
the challenging ILSVRC 2012 dataset.

text: Pools of air cooled by partial rain evaporation span up to several hundreds
of kilometers in nature and typically last less than 1 day, ultimately losing
their identity to the large-scale flow. These fundamentally differ in character
from the radiatively-driven dry pools defining convective aggregation. Advancement
in remote sensing and in computer capabilities has promoted exploration of how
precipitation-induced cold pool processes modify the convective spectrum and life
cycle. This contribution surveys current understanding of such cold pools over
the tropical and subtropical oceans. In shallow convection with low rain rates,
the cold pools moisten, preserving the near-surface equivalent potential temperature
or increasing it if the surface moisture fluxes cannot ventilate beyond the new
surface layer; both conditions indicate downdraft origin air from within the boundary
layer. When rain rates exceed ∼ 2 mm h−1, convective-scale downdrafts can bring
down drier air of lower equivalent potential temperature from above the boundary
layer. The resulting density currents facilitate the lifting of locally thermodynamically
favorable air and can impose an arc-shaped mesoscale cloud organization. This
organization allows clouds capable of reaching 4–5 km within otherwise dry environments.
These are more commonly observed in the northern hemisphere trade wind regime,
where the flow to the intertropical convergence zone is unimpeded by the equator.
Their near-surface air properties share much with those shown from cold pools
sampled in the equatorial Indian Ocean. Cold pools are most effective at influencing
the mesoscale organization when the atmosphere is moist in the lower free troposphere
and dry above, suggesting an optimal range of water vapor paths. Outstanding questions
on the relationship between cold pools, their accompanying moisture distribution
and cloud cover are detailed further. Near-surface water vapor rings are documented
in one model inside but near the cold pool edge; these are not consistent with
observations, but do improve with smaller horizontal grid spacings.

text: Convective self-aggregation, the spontaneous organization of initially scattered
convection into isolated convective clusters despite spatially homogeneous boundary
conditions and forcing, was first recognized and studied in idealized numerical
simulations. While there is a rich history of observational work on convective
clustering and organization, there have been only a few studies that have analyzed
observations to look specifically for processes related to self-aggregation in
models. Here we review observational work in both of these categories and motivate
the need for more of this work. We acknowledge that self-aggregation may appear
to be far-removed from observed convective organization in terms of time scales,
initial conditions, initiation processes, and mean state extremes, but we argue
that these differences vary greatly across the diverse range of model simulations
in the literature and that these comparisons are already offering important insights
into real tropical phenomena. Some preliminary new findings are presented, including
results showing that a self-aggregation simulation with square geometry has too
broad distribution of humidity and is too dry in the driest regions when compared
with radiosonde records from Nauru, while an elongated channel simulation has
realistic representations of atmospheric humidity and its variability. We discuss
recent work increasing our understanding of how organized convection and climate
change may interact, and how model discrepancies related to this question are
prompting interest in observational comparisons. We also propose possible future
directions for observational work related to convective aggregation, including
novel satellite approaches and a ground-based observational network.

text: Infections with potentially lethal pathogens may negatively affect an individual’s
lifespan and decrease its reproductive value. The terminal investment hypothesis
predicts that individuals faced with a reduced survival should invest more into
reproduction instead of maintenance and growth. Several studies suggest that individuals
are indeed able to estimate their body condition and to increase their reproductive
effort with approaching death, while other studies gave ambiguous results. We
investigate whether queens of a perennial social insect (ant) are able to boost
their reproduction following infection with an obligate killing pathogen. Social
insect queens are special with regard to reproduction and aging, as they outlive
conspecific non-reproductive workers. Moreover, in the ant Cardiocondyla obscurior,
fecundity increases with queen age. However, it remained unclear whether this
reflects negative reproductive senescence or terminal investment in response to
approaching death. Here, we test whether queens of C. obscurior react to infection
with the entomopathogenic fungus Metarhizium brunneum by an increased egg-laying
rate. We show that a fungal infection triggers a reinforced investment in reproduction
in queens. This adjustment of the reproductive rate by ant queens is consistent
with predictions of the terminal investment hypothesis and is reported for the
first time in a social insect.

text: We propose a dual decomposition and linear program relaxation of the NP-hard
minimum cost multicut problem. Unlike other polyhedral relaxations of the multicut
polytope, it is amenable to efficient optimization by message passing. Like other
polyhedral relaxations, it can be tightened efficiently by cutting planes. We
define an algorithm that alternates between message passing and efficient separation
of cycle- and odd-wheel inequalities. This algorithm is more efficient than state-of-the-art
algorithms based on linear programming, including algorithms written in the framework
of leading commercial software, as we show in experiments with large instances
of the problem from applications in computer vision, biomedical image analysis
and data mining.

text: Previous numerical studies of the dissipation of internal tides in idealized
settings suggest the existence of a critical latitude (~29°) where dissipation
is enhanced. But observations only indicate a modest enhancement at this latitude.
To resolve this difference between observational and numerical results, the authors
study the latitudinal dependence of internal tides’ dissipation in more realistic
conditions. In particular, the ocean is not a quiescent medium; the presence of
large-scale currents or mesoscale eddies can impact the propagation and dissipation
of internal tides. This paper investigates the impact of a weak background mean
current in numerical simulations. The authors focus on the local dissipation of
high spatial mode internal waves near their generation site. The vertical profile
of dissipation and its variation with latitude without the mean current are consistent
with earlier studies. But adding a weak mean current has a major impact on the
latitudinal distribution of dissipation. The peak at the critical latitude disappears,
and the dissipation is closer to a constant, albeit with two weak peaks at ~25°
and ~35° latitude. This disappearance results from the Doppler shift of the internal
tides’ frequency, which hinders the nonlinear transfer of energy to small-scale
secondary waves via the parametric subharmonic instability (PSI). The new two
weak peaks correspond to the Doppler-shifted critical latitudes of the left- and
right-propagating waves. The results are confirmed in simulations with simple
sinusoidal topography. Thus, although nonlinear transfers via PSI are efficient
at dissipating internal tides, the exact location of the dissipation is sensitive
to large-scale oceanic conditions.

text: We study the quadratic assignment problem, in computer vision also known as
graph matching. Two leading solvers for this problem optimize the Lagrange decomposition
duals with sub-gradient and dual ascent (also known as message passing) updates.
We explore this direction further and propose several additional Lagrangean relaxations
of the graph matching problem along with corresponding algorithms, which are all
based on a common dual ascent framework. Our extensive empirical evaluation gives
several theoretical insights and suggests a new state-of-the-art anytime solver
for the considered problem. Our improvement over state-of-the-art is particularly
visible on a new dataset with large-scale sparse problem instances containing
more than 500 graph nodes each.

text: We propose a general dual ascent framework for Lagrangean decomposition
of combinatorial problems. Although methods of this type have shown their efficiency
for a number of problems, so far there was no general algorithm applicable to
multiple problem types. In this work, we propose such a general algorithm. It
depends on several parameters, which can be used to optimize its performance in
each particular setting. We demonstrate efficacy of our method on graph matching
and multicut problems, where it outperforms state-of-the-art solvers including
those based on subgradient optimization and off-the-shelf linear programming solvers.

text: Plant meristems carry pools of continuously active stem cells, whose
activity is controlled by developmental and environmental signals. After stem
cell division, daughter cells that exit the stem cell domain acquire transit amplifying
cell identity before they are incorporated into organs and differentiate. In this
study, we used an integrated approach to elucidate the role of HECATE (HEC) genes
in regulating developmental trajectories of shoot stem cells in Arabidopsis thaliana.
Our work reveals that HEC function stabilizes cell fate in distinct zones of the
shoot meristem thereby controlling the spatio-temporal dynamics of stem cell differentiation.
Importantly, this activity is concomitant with the local modulation of cellular
responses to cytokinin and auxin, two key phytohormones regulating cell behaviour.
Mechanistically, we show that HEC factors transcriptionally control and physically
interact with MONOPTEROS (MP), a key regulator of auxin signalling, and modulate
the autocatalytic stabilization of auxin signalling output.

text: An electro-optomechanical device capable of microwave-to-optics conversion
has recently been demonstrated, with the vision of enabling optical networks of
superconducting qubits. Here we present an improved converter design that uses
a three-dimensional microwave cavity for coupling between the microwave transmission
line and an integrated LC resonator on the converter chip. The new design simplifies
the optical assembly and decouples it from the microwave part of the setup. Experimental
demonstrations show that the modular device assembly allows us to flexibly tune
the microwave coupling to the converter chip while maintaining small loss. We
also find that electromechanical experiments are not impacted by the additional
microwave cavity. Our design is compatible with a high-finesse optical cavity
and will improve optical performance.

text: The thesis encompasses several topics of plant cell biology which were studied
in the model plant Arabidopsis thaliana. Chapter 1 concerns the plant hormone
auxin and its polar transport through cells and tissues. The highly controlled,
directional transport of auxin is facilitated by plasma membrane-localized transporters.
Transporters from the PIN family direct auxin transport due to their polarized
localizations at cell membranes. Substantial effort has been put into research
on cellular trafficking of PIN proteins, which is thought to underlie their polar
distribution. I participated in a forward genetic screen aimed at identifying
novel regulators of PIN polarity. The screen yielded several genes which may be
involved in PIN polarity regulation or participate in polar auxin transport by
other means. Chapter 2 focuses on the endomembrane system, with particular attention
to clathrin-mediated endocytosis. The project started with identification of several
proteins that interact with clathrin light chains. Among them, I focused on two
putative homologues of auxilin, which in non-plant systems is an endocytotic factor
known for uncoating clathrin-coated vesicles in the final step of endocytosis.
The body of my work consisted of an in-depth characterization of transgenic A.
thaliana lines overexpressing these putative auxilins in an inducible manner.
Overexpression of these proteins leads to an inhibition of endocytosis, as documented
by imaging of cargoes and clathrin-related endocytic machinery. An extension of
this work is an investigation into a concept of homeostatic regulation acting
between distinct transport processes in the endomembrane system. With auxilin
overexpressing lines, where endocytosis is blocked specifically, I made observations
on the mutual relationship between two opposite trafficking processes of secretion
and endocytosis. In Chapter 3, I analyze cortical microtubule arrays and their
relationship to auxin signaling and polarized growth in elongating cells. In plants,
microtubules are organized into arrays just below the plasma membrane, and it
is thought that their function is to guide membrane-docked cellulose synthase
complexes. These, in turn, influence cell wall structure and cell shape by directed
deposition of cellulose fibres. In elongating cells, cortical microtubule arrays
are able to reorient in relation to long cell axis, and these reorientations have
been linked to cell growth and to signaling of growth-regulating factors such
as auxin or light. In this chapter, I am addressing the causal relationship between
microtubule array reorientation, growth, and auxin signaling. I arrive at a model
where array reorientation is not guided by auxin directly, but instead is only
controlled by growth, which, in turn, is regulated by auxin.

text: We reveal the existence of continuous families of guided single-mode solitons
in planar waveguides with weakly nonlinear active core and absorbing boundaries.
Stable propagation of TE and TM-polarized solitons is accompanied by attenuation
of all other modes, i.e., the waveguide features properties of conservative and
dissipative systems. If the linear spectrum of the waveguide possesses exceptional
points, which occurs in the case of TM polarization, an originally focusing (defocusing)
material nonlinearity may become effectively defocusing (focusing). This occurs
due to the geometric phase of the carried eigenmode when the surface impedance
encircles the exceptional point. In its turn, the change of the effective nonlinearity
ensures the existence of dark (bright) solitons in spite of focusing (defocusing)
Kerr nonlinearity of the core. The existence of an exceptional point can also
result in anomalous enhancement of the effective nonlinearity. In terms of practical
applications, the nonlinearity of the reported waveguide can be manipulated by
controlling the properties of the absorbing cladding.

text: We introduce a method for breaking Lorentz reciprocity based upon the noncommutation
of frequency conversion and delay. The method requires no magnetic materials or
resonant physics, allowing for the design of scalable and broadband nonreciprocal
circuits. With this approach, two types of gyrators - universal building blocks
for linear, nonreciprocal circuits - are constructed. Using one of these gyrators,
we create a circulator with >15 dB of isolation across the 5-9 GHz band. Our
designs may be readily extended to any platform with suitable frequency conversion
elements, including semiconducting devices for telecommunication or an on-chip
superconducting implementation for quantum information processing.

text: 'Many central synapses contain a single presynaptic active zone and a single
postsynaptic density. Vesicular release statistics at such “simple synapses” indicate
that they contain a small complement of docking sites where vesicles repetitively
dock and fuse. In this work, we investigate functional and morphological aspects
of docking sites at simple synapses made between cerebellar parallel fibers and
molecular layer interneurons. Using immunogold labeling of SDS-treated freeze-fracture
replicas, we find that Cav2.1 channels form several clusters per active zone with
about nine channels per cluster. The mean value and range of intersynaptic variation
are similar for Cav2.1 cluster numbers and for functional estimates of docking-site
numbers obtained from the maximum numbers of released vesicles per action potential.
Both numbers grow in relation with synaptic size and decrease by a similar extent
with age between 2 wk and 4 wk postnatal. Thus, the mean docking-site numbers
were 3.15 at 2 wk (range: 1–10) and 2.03 at 4 wk (range: 1–4), whereas the mean
numbers of Cav2.1 clusters were 2.84 at 2 wk (range: 1–8) and 2.37 at 4 wk (range:
1–5). These changes were accompanied by decreases of miniature current amplitude
(from 93 pA to 56 pA), active-zone surface area (from 0.0427 μm2 to 0.0234 μm2),
and initial success rate (from 0.609 to 0.353), indicating a tightening of synaptic
transmission with development. Altogether, these results suggest a close correspondence
between the number of functionally defined vesicular docking sites and that of
clusters of voltage-gated calcium channels. '

text: A change regarding the extent of adhesion - hereafter referred to as adhesion
plasticity - between adhesive and less-adhesive states of mammalian cells is important
for their behavior. To investigate adhesion plasticity, we have selected a stable
isogenic subpopulation of human MDA-MB-468 breast carcinoma cells growing in suspension.
These suspension cells are unable to re-adhere to various matrices or to contract
three-dimensional collagen lattices. By using transcriptome analysis, we identified
the focal adhesion protein tensin3 (Tns3) as a determinant of adhesion plasticity.
Tns3 is strongly reduced at mRNA and protein levels in suspension cells. Furthermore,
by transiently challenging breast cancer cells to grow under non-adherent conditions
markedly reduces Tns3 protein expression, which is regained upon re-adhesion.
Stable knockdown of Tns3 in parental MDA-MB-468 cells results in defective adhesion,
spreading and migration. Tns3-knockdown cells display impaired structure and dynamics
of focal adhesion complexes as determined by immunostaining. Restoration of Tns3
protein expression in suspension cells partially rescues adhesion and focal contact
composition. Our work identifies Tns3 as a crucial focal adhesion component regulated
by, and functionally contributing to, the switch between adhesive and non-adhesive
states in MDA-MB-468 cancer cells.

text: Mutator strains are expected to evolve when the availability and effect of
beneficial mutations are high enough to counteract the disadvantage from deleterious
mutations that will inevitably accumulate. As the population becomes more adapted
to its environment, both availability and effect of beneficial mutations necessarily
decrease and mutation rates are predicted to decrease. It has been shown that
certain molecular mechanisms can lead to increased mutation rates when the organism
finds itself in a stressful environment. While this may be a correlated response
to other functions, it could also be an adaptive mechanism, raising mutation rates
only when it is most advantageous. Here, we use a mathematical model to investigate
the plausibility of the adaptive hypothesis. We show that such a mechanism can
be mantained if the population is subjected to diverse stresses. By simulating
various antibiotic treatment schemes, we find that combination treatments can
reduce the effectiveness of second-order selection on stress-induced mutagenesis.
We discuss the implications of our results to strategies of antibiotic therapy.
