text: Bacteria regulate genes to survive antibiotic stress, but regulation can be
far from perfect. When regulation is not optimal, mutations that change gene expression
can contribute to antibiotic resistance. It is not systematically understood to
what extent natural gene regulation is or is not optimal for distinct antibiotics,
and how changes in expression of specific genes quantitatively affect antibiotic
resistance. Here we discover a simple quantitative relation between fitness, gene
expression, and antibiotic potency, which rationalizes our observation that a
multitude of genes and even innate antibiotic defense mechanisms have expression
that is critically nonoptimal under antibiotic treatment. First, we developed
a pooled-strain drug-diffusion assay and screened Escherichia coli overexpression
and knockout libraries, finding that resistance to a range of 31 antibiotics could
result from changing expression of a large and functionally diverse set of genes,
in a primarily but not exclusively drug-specific manner. Second, by synthetically
controlling the expression of single-drug and multidrug resistance genes, we observed
that their fitness-expression functions changed dramatically under antibiotic
treatment in accordance with a log-sensitivity relation. Thus, because many genes
are nonoptimally expressed under antibiotic treatment, many regulatory mutations
can contribute to resistance by altering expression and by activating latent defenses.

text: The German cockroach, Blattella germanica, is a worldwide pest that infests
buildings, including homes, restaurants, and hospitals, often living in unsanitary
conditions. As a disease vector and producer of allergens, this species has major
health and economic impacts on humans. Factors contributing to the success of
the German cockroach include its resistance to a broad range of insecticides,
immunity to many pathogens, and its ability, as an extreme generalist omnivore,
to survive on most food sources. The recently published genome shows that B. germanica
has an exceptionally high number of protein coding genes. In this study, we investigate
the functions of the 93 significantly expanded gene families with the aim to better
understand the success of B. germanica as a major pest despite such inhospitable
conditions. We find major expansions in gene families with functions related to
the detoxification of insecticides and allelochemicals, defense against pathogens,
digestion, sensory perception, and gene regulation. These expansions might have
allowed B. germanica to develop multiple resistance mechanisms to insecticides
and pathogens, and enabled a broad, flexible diet, thus explaining its success
in unsanitary conditions and under recurrent chemical control. The findings and
resources presented here provide insights for better understanding molecular mechanisms
that will facilitate more effective cockroach control.

text: Intercellular distribution of the plant hormone auxin largely depends on the
polar subcellular distribution of the plasma membrane PIN-FORMED (PIN) auxin transporters.
PIN polarity switches in response to different developmental and environmental
signals have been shown to redirect auxin fluxes mediating certain developmental
responses. PIN phosphorylation at different sites and by different kinases is
crucial for PIN function. Here we investigate the role of PIN phosphorylation
during gravitropic response. Loss- and gain-of-function mutants in PINOID and
related kinases but not in D6PK kinase as well as mutations mimicking constitutive
dephosphorylated or phosphorylated status of two clusters of predicted phosphorylation
sites partially disrupted PIN3 phosphorylation and caused defects in gravitropic
bending in roots and hypocotyls. In particular, they impacted PIN3 polarity rearrangements
in response to gravity and during feed-back regulation by auxin itself. Thus PIN
phosphorylation, besides regulating transport activity and apical-basal targeting,
is also important for the rapid polarity switches in response to environmental
and endogenous signals.

text: The phytohormone auxin is the information carrier in a plethora of developmental
and physiological processes in plants(1). It has been firmly established that
canonical, nuclear auxin signalling acts through regulation of gene transcription(2).
Here, we combined microfluidics, live imaging, genetic engineering and computational
modelling to reanalyse the classical case of root growth inhibition(3) by auxin.
We show that Arabidopsis roots react to addition and removal of auxin by extremely
rapid adaptation of growth rate. This process requires intracellular auxin perception
but not transcriptional reprogramming. The formation of the canonical TIR1/AFB-Aux/IAA
co-receptor complex is required for the growth regulation, hinting to a novel,
non-transcriptional branch of this signalling pathway. Our results challenge the
current understanding of root growth regulation by auxin and suggest another,
presumably non-transcriptional, signalling output of the canonical auxin pathway.

text: 'We show attacks on five data-independent memory-hard functions (iMHF) that
were submitted to the password hashing competition (PHC). Informally, an MHF is
a function which cannot be evaluated on dedicated hardware, like ASICs, at significantly
lower hardware and/or energy cost than evaluating a single instance on a standard
single-core architecture. Data-independent means the memory access pattern of
the function is independent of the input; this makes iMHFs harder to construct
than data-dependent ones, but the latter can be attacked by various side-channel
attacks. Following [Alwen-Blocki''16], we capture the evaluation of an iMHF as
a directed acyclic graph (DAG). The cumulative parallel pebbling complexity of
this DAG is a measure for the hardware cost of evaluating the iMHF on an ASIC.
Ideally, one would like the complexity of a DAG underlying an iMHF to be as close
to quadratic in the number of nodes of the graph as possible. Instead, we show
that (the DAGs underlying) the following iMHFs are far from this bound: Rig.v2,
TwoCats and Gambit each having an exponent no more than 1.75. Moreover, we show
that the complexity of the iMHF modes of the PHC finalists Pomelo and Lyra2 have
exponents at most 1.83 and 1.67 respectively. To show this we investigate a combinatorial
property of each underlying DAG (called its depth-robustness. By establishing
upper bounds on this property we are then able to apply the general technique
of [Alwen-Block''16] for analyzing the hardware costs of an iMHF.'

text: Ants are emerging model systems to study cellular signaling because distinct
castes possess different physiologic phenotypes within the same colony. Here we
studied the functionality of inotocin signaling, an insect ortholog of mammalian
oxytocin (OT), which was recently discovered in ants. In Lasius ants, we determined
that specialization within the colony, seasonal factors, and physiologic conditions
down-regulated the expression of the OT-like signaling system. Given this natural
variation, we interrogated its function using RNAi knockdowns. Next-generation
RNA sequencing of OT-like precursor knock-down ants highlighted its role in the
regulation of genes involved in metabolism. Knock-down ants exhibited higher walking
activity and increased self-grooming in the brood chamber. We propose that OT-like
signaling in ants is important for regulating metabolic processes and locomotion.

text: We demonstrate that identical impurities immersed in a two-dimensional many-particle
bath can be viewed as flux-tube-charged-particle composites described by fractional
statistics. In particular, we find that the bath manifests itself as an external
magnetic flux tube with respect to the impurities, and hence the time-reversal
symmetry is broken for the effective Hamiltonian describing the impurities. The
emerging flux tube acts as a statistical gauge field after a certain critical
coupling. This critical coupling corresponds to the intersection point between
the quasiparticle state and the phonon wing, where the angular momentum is transferred
from the impurity to the bath. This amounts to a novel configuration with emerging
anyons. The proposed setup paves the way to realizing anyons using electrons interacting
with superfluid helium or lattice phonons, as well as using atomic impurities
in ultracold gases.

text: Modern computer vision systems heavily rely on statistical machine learning
models, which typically require large amounts of labeled data to be learned reliably.
Moreover, very recently computer vision research widely adopted techniques for
representation learning, which further increase the demand for labeled data. However,
for many important practical problems there is relatively small amount of labeled
data available, so it is problematic to leverage full potential of the representation
learning methods. One way to overcome this obstacle is to invest substantial resources
into producing large labelled datasets. Unfortunately, this can be prohibitively
expensive in practice. In this thesis we focus on the alternative way of tackling
the aforementioned issue. We concentrate on methods, which make use of weakly-labeled
or even unlabeled data. Specifically, the first half of the thesis is dedicated
to the semantic image segmentation task. We develop a technique, which achieves
competitive segmentation performance and only requires annotations in a form of
global image-level labels instead of dense segmentation masks. Subsequently, we
present a new methodology, which further improves segmentation performance by
leveraging tiny additional feedback from a human annotator. By using our methods
practitioners can greatly reduce the amount of data annotation effort, which is
required to learn modern image segmentation models. In the second half of the
thesis we focus on methods for learning from unlabeled visual data. We study a
family of autoregressive models for modeling structure of natural images and discuss
potential applications of these models. Moreover, we conduct in-depth study of
one of these applications, where we develop the state-of-the-art model for the
probabilistic image colorization task.

text: We consider a class of students learning a language from a teacher. The situation
can be interpreted as a group of child learners receiving input from the linguistic
environment. The teacher provides sample sentences. The students try to learn
the grammar from the teacher. In addition to just listening to the teacher, the
students can also communicate with each other. The students hold hypotheses about
the grammar and change them if they receive counter evidence. The process stops
when all students have converged to the correct grammar. We study how the time
to convergence depends on the structure of the classroom by introducing and evaluating
various complexity measures. We find that structured communication between students,
although potentially introducing confusion, can greatly reduce some of the complexity
measures. Our theory can also be interpreted as applying to the scientific process,
where nature is the teacher and the scientists are the students.

text: Sex-biased genes are central to the study of sexual selection, sexual antagonism,
and sex chromosome evolution. We describe a comprehensive de novo assembled transcriptome
in the common frog Rana temporaria based on five developmental stages and three
adult tissues from both sexes, obtained from a population with karyotypically
homomorphic but genetically differentiated sex chromosomes. This allows the study
of sex-biased gene expression throughout development, and its effect on the rate
of gene evolution while accounting for pleiotropic expression, which is known
to negatively correlate with the evolutionary rate. Overall, sex-biased genes
had little overlap among developmental stages and adult tissues. Late developmental
stages and gonad tissues had the highest numbers of stage-or tissue-specific genes.
We find that pleiotropic gene expression is a better predictor than sex bias for
the evolutionary rate of genes, though it often interacts with sex bias. Although
genetically differentiated, the sex chromosomes were not enriched in sex-biased
genes, possibly due to a very recent arrest of XY recombination. These results
extend our understanding of the developmental dynamics, tissue specificity, and
genomic localization of sex-biased genes.

text: Indirect reciprocity explores how humans act when their reputation is at stake,
and which social norms they use to assess the actions of others. A crucial question
in indirect reciprocity is which social norms can maintain stable cooperation
in a society. Past research has highlighted eight such norms, called “leading-eight”
strategies. This past research, however, is based on the assumption that all relevant
information about other population members is publicly available and that everyone
agrees on who is good or bad. Instead, here we explore the reputation dynamics
when information is private and noisy. We show that under these conditions, most
leading-eight strategies fail to evolve. Those leading-eight strategies that do
evolve are unable to sustain full cooperation.Indirect reciprocity is a mechanism
for cooperation based on shared moral systems and individual reputations. It assumes
that members of a community routinely observe and assess each other and that they
use this information to decide who is good or bad, and who deserves cooperation.
When information is transmitted publicly, such that all community members agree
on each other’s reputation, previous research has highlighted eight crucial moral
systems. These “leading-eight” strategies can maintain cooperation and resist
invasion by defectors. However, in real populations individuals often hold their
own private views of others. Once two individuals disagree about their opinion
of some third party, they may also see its subsequent actions in a different light.
Their opinions may further diverge over time. Herein, we explore indirect reciprocity
when information transmission is private and noisy. We find that in the presence
of perception errors, most leading-eight strategies cease to be stable. Even if
a leading-eight strategy evolves, cooperation rates may drop considerably when
errors are common. Our research highlights the role of reliable information and
synchronized reputations to maintain stable moral systems.

text: 'Background: Norepinephrine (NE) signaling has a key role in white adipose
tissue (WAT) functions, including lipolysis, free fatty acid liberation and, under
certain conditions, conversion of white into brite (brown-in-white) adipocytes.
However, acute effects of NE stimulation have not been described at the transcriptional
network level. Results: We used RNA-seq to uncover a broad transcriptional response.
The inference of protein-protein and protein-DNA interaction networks allowed
us to identify a set of immediate-early genes (IEGs) with high betweenness, validating
our approach and suggesting a hierarchical control of transcriptional regulation.
In addition, we identified a transcriptional regulatory network with IEGs as master
regulators, including HSF1 and NFIL3 as novel NE-induced IEG candidates. Moreover,
a functional enrichment analysis and gene clustering into functional modules suggest
a crosstalk between metabolic, signaling, and immune responses. Conclusions: Altogether,
our network biology approach explores for the first time the immediate-early systems
level response of human adipocytes to acute sympathetic activation, thereby providing
a first network basis of early cell fate programs and crosstalks between metabolic
and transcriptional networks required for proper WAT function.'

text: This thesis is concerned with the inference of current population structure
based on geo-referenced genetic data. The underlying idea is that population structure
affects its spatial genetic structure. Therefore, genotype information can be
utilized to estimate important demographic parameters such as migration rates.
These indirect estimates of population structure have become very attractive,
as genotype data is now widely available. However, there also has been much concern
about these approaches. Importantly, genetic structure can be influenced by many
complex patterns, which often cannot be disentangled. Moreover, many methods merely
fit heuristic patterns of genetic structure, and do not build upon population
genetics theory. Here, I describe two novel inference methods that address these
shortcomings. In Chapter 2, I introduce an inference scheme based on a new type
of signal, identity by descent (IBD) blocks. Recently, it has become feasible
to detect such long blocks of genome shared between pairs of samples. These blocks
are direct traces of recent coalescence events. As such, they contain ample signal
for inferring recent demography. I examine sharing of IBD blocks in two-dimensional
populations with local migration. Using a diffusion approximation, I derive formulas
for an isolation by distance pattern of long IBD blocks and show that sharing
of long IBD blocks approaches rapid exponential decay for growing sample distance.
I describe an inference scheme based on these results. It can robustly estimate
the dispersal rate and population density, which is demonstrated on simulated
data. I also show an application to estimate mean migration and the rate of recent
population growth within Eastern Europe. Chapter 3 is about a novel method to
estimate barriers to gene flow in a two dimensional population. This inference
scheme utilizes geographically localized allele frequency fluctuations - a classical
isolation by distance signal. The strength of these local fluctuations increases
on average next to a barrier, and there is less correlation across it. I again
use a framework of diffusion of ancestral lineages to model this effect, and provide
an efficient numerical implementation to fit the results to geo-referenced biallelic
SNP data. This inference scheme is able to robustly estimate strong barriers to
gene flow, as tests on simulated data confirm.

text: 'We describe arrangements of three-dimensional spheres from a geometrical
and topological point of view. Real data (fitting this setup) often consist of
soft spheres which show certain degree of deformation while strongly packing against
each other. In this context, we answer the following questions: If we model a
soft packing of spheres by hard spheres that are allowed to overlap, can we measure
the volume in the overlapped areas? Can we be more specific about the overlap
volume, i.e. quantify how much volume is there covered exactly twice, three times,
or k times? What would be a good optimization criteria that rule the arrangement
of soft spheres while making a good use of the available space? Fixing a particular
criterion, what would be the optimal sphere configuration? The first result of
this thesis are short formulas for the computation of volumes covered by at least
k of the balls. The formulas exploit information contained in the order-k Voronoi
diagrams and its closely related Level-k complex. The used complexes lead to a
natural generalization into poset diagrams, a theoretical formalism that contains
the order-k and degree-k diagrams as special cases. In parallel, we define different
criteria to determine what could be considered an optimal arrangement from a geometrical
point of view. Fixing a criterion, we find optimal soft packing configurations
in 2D and 3D where the ball centers lie on a lattice. As a last step, we use tools
from computational topology on real physical data, to show the potentials of higher-order
diagrams in the description of melting crystals. The results of the experiments
leaves us with an open window to apply the theories developed in this thesis in
real applications.'

text: Asymmetric auxin distribution is instrumental for the differential growth
that causes organ bending on tropic stimuli and curvatures during plant development.
Local differences in auxin concentrations are achieved mainly by polarized cellular
distribution of PIN auxin transporters, but whether other mechanisms involving
auxin homeostasis are also relevant for the formation of auxin gradients is not
clear. Here we show that auxin methylation is required for asymmetric auxin distribution
across the hypocotyl, particularly during its response to gravity. We found that
loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1)
prematurely unfold the apical hook, and that their hypocotyls are impaired in
gravitropic reorientation. This defect is linked to an auxin-dependent increase
in PIN gene expression, leading to an increased polar auxin transport and lack
of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation
in the iamt1 mutant could be restored with either endodermis-specific expression
of IAMT1 or partial inhibition of polar auxin transport, which also results in
normal PIN gene expression levels. We propose that IAA methylation is necessary
in gravity-sensing cells to restrict polar auxin transport within the range of
auxin levels that allow for differential responses.

text: "The current state of the art in real-time two-dimensional water wave simulation
requires developers to choose between efficient Fourier-based methods, which lack
interactions with moving obstacles, and finite-difference or finite element methods,
which handle environmental interactions but are significantly more expensive.
This paper attempts to bridge this long-standing gap between complexity and performance,
by proposing a new wave simulation method that can faithfully simulate wave interactions
with moving obstacles in real time while simultaneously preserving minute details
and accommodating very large simulation domains.\r\n\r\nPrevious methods for simulating
2D water waves directly compute the change in height of the water surface, a strategy
which imposes limitations based on the CFL condition (fast moving waves require
small time steps) and Nyquist's limit (small wave details require closely-spaced
simulation variables). This paper proposes a novel wavelet transformation that
discretizes the liquid motion in terms of amplitude-like functions that vary over
space, frequency, and direction, effectively generalizing Fourier-based methods
to handle local interactions. Because these new variables change much more slowly
over space than the original water height function, our change of variables drastically
reduces the limitations of the CFL condition and Nyquist limit, allowing us to
simulate highly detailed water waves at very large visual resolutions. Our discretization
is amenable to fast summation and easy to parallelize. We also present basic extensions
like pre-computed wave paths and two-way solid fluid coupling. Finally, we argue
that our discretization provides a convenient set of variables for artistic manipulation,
which we illustrate with a novel wave-painting interface."

text: The Fluid Implicit Particle method (FLIP) reduces numerical dissipation by
combining particles with grids. To improve performance, the subsequent narrow
band FLIP method (NB‐FLIP) uses a FLIP‐based fluid simulation only near the liquid
surface and a traditional grid‐based fluid simulation away from the surface. This
spatially‐limited FLIP simulation significantly reduces the number of particles
and alleviates a computational bottleneck. In this paper, we extend the NB‐FLIP
idea even further, by allowing a simulation to transition between a FLIP‐like
fluid simulation and a grid‐based simulation in arbitrary locations, not just
near the surface. This approach leads to even more savings in memory and computation,
because we can concentrate the particles only in areas where they are needed.
More importantly, this new method allows us to seamlessly transition to smooth
implicit surface geometry wherever the particle‐based simulation is unnecessary.
Consequently, our method leads to a practical algorithm for avoiding the noisy
surface artifacts associated with particle‐based liquid simulations, while simultaneously
maintaining the benefits of a FLIP simulation in regions of dynamic motion.

text: Recent studies suggest that unstable, nonchaotic solutions of the Navier-Stokes
equation may provide deep insights into fluid turbulence. In this article, we
present a combined experimental and numerical study exploring the dynamical role
of unstable equilibrium solutions and their invariant manifolds in a weakly turbulent,
electromagnetically driven, shallow fluid layer. Identifying instants when turbulent
evolution slows down, we compute 31 unstable equilibria of a realistic two-dimensional
model of the flow. We establish the dynamical relevance of these unstable equilibria
by showing that they are closely visited by the turbulent flow. We also establish
the dynamical relevance of unstable manifolds by verifying that they are shadowed
by turbulent trajectories departing from the neighborhoods of unstable equilibria
over large distances in state space.

text: Fluorescent sensors are an essential part of the experimental toolbox of the
life sciences, where they are used ubiquitously to visualize intra- and extracellular
signaling. In the brain, optical neurotransmitter sensors can shed light on temporal
and spatial aspects of signal transmission by directly observing, for instance,
neurotransmitter release and spread. Here we report the development and application
of the first optical sensor for the amino acid glycine, which is both an inhibitory
neurotransmitter and a co-agonist of the N-methyl-d-aspartate receptors (NMDARs)
involved in synaptic plasticity. Computational design of a glycine-specific binding
protein allowed us to produce the optical glycine FRET sensor (GlyFS), which can
be used with single and two-photon excitation fluorescence microscopy. We took
advantage of this newly developed sensor to test predictions about the uneven
spatial distribution of glycine in extracellular space and to demonstrate that
extracellular glycine levels are controlled by plasticity-inducing stimuli.

text: 'Genome-scale diversity data are increasingly available in a variety of biological
systems, and can be used to reconstruct the past evolutionary history of species
divergence. However, extracting the full demographic information from these data
is not trivial, and requires inferential methods that account for the diversity
of coalescent histories throughout the genome. Here, we evaluate the potential
and limitations of one such approach. We reexamine a well-known system of mussel
sister species, using the joint site frequency spectrum (jSFS) of synonymousmutations
computed either fromexome capture or RNA-seq, in an Approximate Bayesian Computation
(ABC) framework. We first assess the best sampling strategy (number of: individuals,
loci, and bins in the jSFS), and show that model selection is robust to variation
in the number of individuals and loci. In contrast, different binning choices
when summarizing the jSFS, strongly affect the results: including classes of low
and high frequency shared polymorphisms can more effectively reveal recent migration
events. We then take advantage of the flexibility of ABC to compare more realistic
models of speciation, including variation in migration rates through time (i.e.,
periodic connectivity) and across genes (i.e., genome-wide heterogeneity in migration
rates). We show that these models were consistently selected as the most probable,
suggesting that mussels have experienced a complex history of gene flow during
divergence and that the species boundary is semi-permeable. Our work provides
a comprehensive evaluation of ABC demographic inference in mussels based on the
coding jSFS, and supplies guidelines for employing different sequencing techniques
and sampling strategies. We emphasize, perhaps surprisingly, that inferences are
less limited by the volume of data, than by the way in which they are analyzed.'
