text: The Ising model is one of the simplest and most famous models of interacting
systems. It was originally proposed to model ferromagnetic interactions in statistical
physics and is now widely used to model spatial processes in many areas such as
ecology, sociology, and genetics, usually without testing its goodness-of-fit.
Here, we propose an exact goodness-of-fit test for the finite-lattice Ising model.
The theory of Markov bases has been developed in algebraic statistics for exact
goodness-of-fit testing using a Monte Carlo approach. However, this beautiful
theory has fallen short of its promise for applications, because finding a Markov
basis is usually computationally intractable. We develop a Monte Carlo method
for exact goodness-of-fit testing for the Ising model which avoids computing a
Markov basis and also leads to a better connectivity of the Markov chain and hence
to a faster convergence. We show how this method can be applied to analyze the
spatial organization of receptors on the cell membrane.

text: 'Restriction-modification (RM) represents the simplest and possibly the most
widespread mechanism of self/non-self discrimination in nature. In order to provide
bacteria with immunity against bacteriophages and other parasitic genetic elements,
RM systems rely on a balance between two enzymes: the restriction enzyme, which
cleaves non-self DNA at specific restriction sites, and the modification enzyme,
which tags the host’s DNA as self and thus protects it from cleavage. In this
thesis, I use population and single-cell level experiments in combination with
mathematical modeling to study different aspects of the interplay between RM systems,
bacteria and bacteriophages. First, I analyze how mutations in phage restriction
sites affect the probability of phage escape – an inherently stochastic process,
during which phages accidently get modified instead of restricted. Next, I use
single-cell experiments to show that RM systems can, with a low probability, attack
the genome of their bacterial host and that this primitive form of autoimmunity
leads to a tradeoff between the evolutionary cost and benefit of RM systems. Finally,
I investigate the nature of interactions between bacteria, RM systems and temperate
bacteriophages to find that, as a consequence of phage escape and its impact on
population dynamics, RM systems can promote acquisition of symbiotic bacteriophages,
rather than limit it. The results presented here uncover new fundamental biological
properties of RM systems and highlight their importance in the ecology and evolution
of bacteria, bacteriophages and their interactions.'
acknowledgement: "During my PhD studies, I received help from many people, all of
which unfortunately cannot be listed here. I thank them deeply and hope that I never
made them regret their kindness.\r\nI would like to express my deepest gratitude
to Călin Guet, who went far beyond his responsibilities as an advisor and was to
me also a great mentor and a friend. Călin never questioned my potential or lacked
compassion and I cannot thank him enough for cultivating in me an independent scientist.
I was amazed by his ability to recognize the most fascinating scientific problems
in objects of study that others would find mundane. I hope I adopted at least a
fraction of this ability.\r\nI will be forever grateful to Bruce Levin for all his
support and especially for giving me the best possible example of how one can practice
excellent science with humor and style. Working with Bruce was a true privilege.\r\nI
thank Jonathan Bollback and Gašper Tkačik for serving in my PhD committee and the
Austrian Academy of Science for funding my PhD research via the DOC fellowship.\r\nI
thank all our lab members: Tobias Bergmiller for his guidance, especially in the
first years of my research, and for being a good friend throughout; Remy Chait for
staying in the lab at unreasonable hours and for the good laughs at bad jokes we
shared; Anna Staron for supportively listening to my whines whenever I had to run
a gel; Magdalena Steinrück for her pioneering work in the lab; Kathrin Tomasek for
keeping the entropic forces in check and for her FACS virtuosity; Isabella Tomanek
for always being nice to me, no matter how much bench space I took from her.\r\nI
thank all my collaborators: Reiko Okura and Yuichi Wakamoto for performing and analyzing
the microfluidic experiments; Long Qian and Edo Kussell for their bioinformatics
analysis; Dominik Refardt for the λ kan phage; Moritz for his help with the mathematical
modeling. I thank Fabienne Jesse for her tireless editorial work on all our manuscripts.\r\nFinally,
I would like to thank my family and especially my wife Edita, who sacrificed a lot
so that I can pursue my goals and dreams.\r\n"

text: 'We report a direct-numerical-simulation study of the Taylor-Couette flow
in the quasi-Keplerian regime at shear Reynolds numbers up to (105). Quasi-Keplerian
rotating flow has been investigated for decades as a simplified model system to
study the origin of turbulence in accretion disks that is not fully understood.
The flow in this study is axially periodic and thus the experimental end-wall
effects on the stability of the flow are avoided. Using optimal linear perturbations
as initial conditions, our simulations find no sustained turbulence: the strong
initial perturbations distort the velocity profile and trigger turbulence that
eventually decays.'

text: 'In this paper, we propose an approach to automatically compute invariant
clusters for nonlinear semialgebraic hybrid systems. An invariant cluster for
an ordinary differential equation (ODE) is a multivariate polynomial invariant
g(u→, x→) = 0, parametric in u→, which can yield an infinite number of concrete
invariants by assigning different values to u→ so that every trajectory of the
system can be overapproximated precisely by the intersection of a group of concrete
invariants. For semialgebraic systems, which involve ODEs with multivariate polynomial
right-hand sides, given a template multivariate polynomial g(u→, x→), an invariant
cluster can be obtained by first computing the remainder of the Lie derivative
of g(u→, x→) divided by g(u→, x→) and then solving the system of polynomial equations
obtained from the coefficients of the remainder. Based on invariant clusters and
sum-of-squares (SOS) programming, we present a new method for the safety verification
of hybrid systems. Experiments on nonlinear benchmark systems from biology and
control theory show that our approach is efficient. '

text: The molecular mechanisms underlying phenotypic variation in isogenic bacterial
populations remain poorly understood.We report that AcrAB-TolC, the main multidrug
efflux pump of Escherichia coli, exhibits a strong partitioning bias for old cell
poles by a segregation mechanism that is mediated by ternary AcrAB-TolC complex
formation. Mother cells inheriting old poles are phenotypically distinct and display
increased drug efflux activity relative to daughters. Consequently, we find systematic
and long-lived growth differences between mother and daughter cells in the presence
of subinhibitory drug concentrations. A simple model for biased partitioning predicts
a population structure of long-lived and highly heterogeneous phenotypes. This
straightforward mechanism of generating sustained growth rate differences at subinhibitory
antibiotic concentrations has implications for understanding the emergence of
multidrug resistance in bacteria.

text: Antibiotics elicit drastic changes in microbial gene expression, including
the induction of stress response genes. While certain stress responses are known
to “cross-protect” bacteria from other stressors, it is unclear whether cellular
responses to antibiotics have a similar protective role. By measuring the genome-wide
transcriptional response dynamics of Escherichia coli to four antibiotics, we
found that trimethoprim induces a rapid acid stress response that protects bacteria
from subsequent exposure to acid. Combining microfluidics with time-lapse imaging
to monitor survival and acid stress response in single cells revealed that the
noisy expression of the acid resistance operon gadBC correlates with single-cell
survival. Cells with higher gadBC expression following trimethoprim maintain higher
intracellular pH and survive the acid stress longer. The seemingly random single-cell
survival under acid stress can therefore be predicted from gadBC expression and
rationalized in terms of GadB/C molecular function. Overall, we provide a roadmap
for identifying the molecular mechanisms of single-cell cross-protection between
antibiotics and other stressors.

text: 'Polar codes represent one of the major recent breakthroughs in coding theory
and, because of their attractive features, they have been selected for the incoming
5G standard. As such, a lot of attention has been devoted to the development of
decoding algorithms with good error performance and efficient hardware implementation.
One of the leading candidates in this regard is represented by successive-cancellation
list (SCL) decoding. However, its hardware implementation requires a large amount
of memory. Recently, a partitioned SCL (PSCL) decoder has been proposed to significantly
reduce the memory consumption [1]. In this paper, we examine the paradigm of PSCL
decoding from both theoretical and practical standpoints: (i) by changing the
construction of the code, we are able to improve the performance at no additional
computational, latency or memory cost, (ii) we present an optimal scheme to allocate
cyclic redundancy checks (CRCs), and (iii) we provide an upper bound on the list
size that allows MAP performance.'

text: Macrophage filopodia, finger-like membrane protrusions, were first implicated
in phagocytosis more than 100 years ago, but little is still known about the involvement
of these actin-dependent structures in particle clearance. Using spinning disk
confocal microscopy to image filopodial dynamics in mouse resident Lifeact-EGFP
macrophages, we show that filopodia, or filopodia-like structures, support pathogen
clearance by multiple means. Filopodia supported the phagocytic uptake of bacterial
(Escherichia coli) particles by (i) capturing along the filopodial shaft and surfing
toward the cell body, the most common mode of capture; (ii) capturing via the
tip followed by retraction; (iii) combinations of surfing and retraction; or (iv)
sweeping actions. In addition, filopodia supported the uptake of zymosan (Saccharomyces
cerevisiae) particles by (i) providing fixation, (ii) capturing at the tip and
filopodia-guided actin anterograde flow with phagocytic cup formation, and (iii)
the rapid growth of new protrusions. To explore the role of filopodia-inducing
Cdc42, we generated myeloid-restricted Cdc42 knock-out mice. Cdc42-deficient macrophages
exhibited rapid phagocytic cup kinetics, but reduced particle clearance, which
could be explained by the marked rounded-up morphology of these cells. Macrophages
lacking Myo10, thought to act downstream of Cdc42, had normal morphology, motility,
and phagocytic cup formation, but displayed markedly reduced filopodia formation.
In conclusion, live-cell imaging revealed multiple mechanisms involving macrophage
filopodia in particle capture and engulfment. Cdc42 is not critical for filopodia
or phagocytic cup formation, but plays a key role in driving macrophage lamellipodial
spreading.

text: 'The exocyst, a eukaryotic tethering complex, coregulates targeted exocytosis
as an effector of small GTPases in polarized cell growth. In land plants, several
exocyst subunits are encoded by double or triple paralogs, culminating in tens
of EXO70 paralogs. Out of 23 Arabidopsis thaliana EXO70 isoforms, we analyzed
seven isoforms expressed in pollen. Genetic and microscopic analyses of single
mutants in EXO70A2, EXO70C1, EXO70C2, EXO70F1, EXO70H3, EXO70H5, and EXO70H6 genes
revealed that only a loss-of-function EXO70C2 allele resulted in a significant
male-specific transmission defect (segregation 40%:51%:9%) due to aberrant pollen
tube growth. Mutant pollen tubes grown in vitro exhibited an enhanced growth rate
and a decreased thickness of the tip cell wall, causing tip bursts. However, exo70C2
pollen tubes could frequently recover and restart their speedy elongation, resulting
in a repetitive stop-and-go growth dynamics. A pollenspecific depletion of the
closest paralog, EXO70C1, using artificial microRNA in the exo70C2 mutant background,
resulted in a complete pollen-specific transmission defect, suggesting redundant
functions of EXO70C1 and EXO70C2. Both EXO70C1 and EXO70C2, GFP tagged and expressed
under the control of their native promoters, localized in the cytoplasm of pollen
grains, pollen tubes, and also root trichoblast cells. The expression of EXO70C2-GFP
complemented the aberrant growth of exo70C2 pollen tubes. The absent EXO70C2 interactions
with core exocyst subunits in the yeast two-hybrid assay, cytoplasmic localization,
and genetic effect suggest an unconventional EXO70 function possibly as a regulator
of exocytosis outside the exocyst complex. In conclusion, EXO70C2 is a novel factor
contributing to the regulation of optimal tip growth of Arabidopsis pollen tubes. '

text: We propose an efficient method to model paper tearing in the context of interactive
modeling. The method uses geometrical information to automatically detect potential
starting points of tears. We further introduce a new hybrid geometrical and physical-based
method to compute the trajectory of tears while procedurally synthesizing high
resolution details of the tearing path using a texture based approach. The results
obtained are compared with real paper and with previous studies on the expected
geometric paths of paper that tears.

text: Humans routinely use conditionally cooperative strategies when interacting
in repeated social dilemmas. They are more likely to cooperate if others cooperated
before, and are ready to retaliate if others defected. To capture the emergence
of reciprocity, most previous models consider subjects who can only choose from
a restricted set of representative strategies, or who react to the outcome of
the very last round only. As players memorize more rounds, the dimension of the
strategy space increases exponentially. This increasing computational complexity
renders simulations for individuals with higher cognitive abilities infeasible,
especially if multiplayer interactions are taken into account. Here, we take an
axiomatic approach instead. We propose several properties that a robust cooperative
strategy for a repeated multiplayer dilemma should have. These properties naturally
lead to a unique class of cooperative strategies, which contains the classical
Win-Stay Lose-Shift rule as a special case. A comprehensive numerical analysis
for the prisoner's dilemma and for the public goods game suggests that strategies
of this class readily evolve across various memory-n spaces. Our results reveal
that successful strategies depend not only on how cooperative others were in the
past but also on the respective context of cooperation.

text: Trafficking cells frequently transmigrate through epithelial and endothelial
monolayers. How monolayers cooperate with the penetrating cells to support their
transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic
capillaries as a model system for transendothelial migration. We find that the
chemokine CCL21, which is the decisive guidance cue for intravasation, mainly
localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial
cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes
extracellularly enriched at the sites of endothelial cell-cell junctions. When
we reconstitute the transmigration process in vitro, we find that secretion of
CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and
selective calcium chelation in lymphatic endothelium attenuates transmigration.
Altogether, our data demonstrate a chemokine-mediated feedback between DCs and
lymphatic endothelium, which facilitates transendothelial migration.

text: Consider the problem of constructing a polar code of block length N for the
transmission over a given channel W. Typically this requires to compute the reliability
of all the N synthetic channels and then to include those that are sufficiently
reliable. However, we know from [1], [2] that there is a partial order among the
synthetic channels. Hence, it is natural to ask whether we can exploit it to reduce
the computational burden of the construction problem. We show that, if we take
advantage of the partial order [1], [2], we can construct a polar code by computing
the reliability of roughly N/ log 3/2 N synthetic channels. Such a set of synthetic
channels is universal, in the sense that it allows one to construct polar codes
for any W, and it can be identified by solving a maximum matching problem on a
bipartite graph. Our proof technique consists in reducing the construction problem
to the problem of computing the maximum cardinality of an antichain for a suitable
partially ordered set. As such, this method is general and it can be used to further
improve the complexity of the construction problem in case a new partial order
on the synthetic channels of polar codes is discovered.

text: We present a numerical study of wavy supercritical cylindrical Couette flow
between counter-rotating cylinders in which the wavy pattern propagates either
prograde with the inner cylinder or retrograde opposite the rotation of the inner
cylinder. The wave propagation reversals from prograde to retrograde and vice
versa occur at distinct values of the inner cylinder Reynolds number when the
associated frequency of the wavy instability vanishes. The reversal occurs for
both twofold and threefold symmetric wavy vortices. Moreover, the wave propagation
reversal only occurs for sufficiently strong counter-rotation. The flow pattern
reversal appears to be intrinsic in the system as either periodic boundary conditions
or fixed end wall boundary conditions for different system sizes always result
in the wave propagation reversal. We present a detailed bifurcation sequence and
parameter space diagram with respect to retrograde behavior of wavy flows. The
retrograde propagation of the instability occurs when the inner Reynolds number
is about two times the outer Reynolds number. The mechanism for the retrograde
propagation is associated with the inviscidly unstable region near the inner cylinder
and the direction of the global average azimuthal velocity. Flow dynamics, spatio-temporal
behavior, global mean angular velocity, and torque of the flow with the wavy pattern
are explored.

text: We introduce a new approach to proving that a sequence of deterministic linear
codes achieves capacity on an erasure channel under maximum a posteriori decoding.
Rather than relying on the precise structure of the codes, our method exploits
code symmetry. In particular, the technique applies to any sequence of linear
codes where the blocklengths are strictly increasing, the code rates converge,
and the permutation group of each code is doubly transitive. In other words, we
show that symmetry alone implies near-optimal performance. An important consequence
of this result is that a sequence of Reed-Muller codes with increasing block length
and converging rate achieves capacity. This possibility has been suggested previously
in the literature but it has only been proven for cases where the limiting code
rate is 0 or 1. Moreover, these results extend naturally to all affine-invariant
codes and, thus, to extended primitive narrow-sense BCH codes. This also resolves,
in the affirmative, the existence question for capacity-achieving sequences of
binary cyclic codes. The primary tools used in the proof are the sharp threshold
property for symmetric monotone Boolean functions and the area theorem for extrinsic
information transfer functions.

text: 'We present a rate-compatible polar coding scheme that achieves the capacity
of any family of channels. Our solution generalizes the previous results [1],
[2] that provide capacity-achieving rate-compatible polar codes for a degraded
family of channels. The motivation for our extension comes from the fact that
in many practical scenarios, e.g., MIMO systems and non-Gaussian interference,
the channels cannot be ordered by degradation. The main technical contribution
of this paper consists in removing the degradation condition. To do so, we exploit
the ideas coming from the construction of universal polar codes. Our scheme possesses
the usual attractive features of polar codes: low complexity code construction,
encoding, and decoding; super-polynomial scaling of the error probability with
the block length; and absence of error floors. On the negative side, the scaling
of the gap to capacity with the block length is slower than in standard polar
codes, and we prove an upper bound on the scaling exponent.'

text: Navigation of cells along gradients of guidance cues is a determining step
in many developmental and immunological processes. Gradients can either be soluble
or immobilized to tissues as demonstrated for the haptotactic migration of dendritic
cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate
how gradient characteristics govern cellular response patterns, we here introduce
an in vitro system allowing to track migratory responses of DCs to precisely controlled
immobilized gradients of CCL21. We find that haptotactic sensing depends on the
absolute CCL21 concentration and local steepness of the gradient, consistent with
a scenario where DC directionality is governed by the signal-to-noise ratio of
CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC
guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore,
we find that CCR7 signal termination by the G-protein-coupled receptor kinase
6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient
sensing in vitro and confirm those observations in vivo. These findings suggest
that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal
guidance in vivo.

text: 'We report the enhancement of infrared absorption of chemisorbed carbon monoxide
on platinum in the gap of plasmonic nanoantennas. Our method is based on the self-assembled
formation of platinum nanoislands on nanoscopic dipole antenna arrays manufactured
via electron beam lithography. We employ systematic variations of the plasmonic
antenna resonance to precisely couple to the molecular stretch vibration of carbon
monoxide adsorbed on the platinum nanoislands. Ultimately, we reach more than
1500-fold infrared absorption enhancements, allowing for an ultrasensitive detection
of a monolayer of chemisorbed carbon monoxide. The developed procedure can be
