text: Cells migrate through crowded microenvironments within tissues during normal
development, immune response, and cancer metastasis. Although migration through
pores and tracks in the extracellular matrix (ECM) has been well studied, little
is known about cellular traversal into confining cell-dense tissues. We find that
embryonic tissue invasion by Drosophila macrophages requires division of an epithelial
ectodermal cell at the site of entry. Dividing ectodermal cells disassemble ECM
attachment formed by integrin-mediated focal adhesions next to mesodermal cells,
allowing macrophages to move their nuclei ahead and invade between two immediately
adjacent tissues. Invasion efficiency depends on division frequency, but reduction
of adhesion strength allows macrophage entry independently of division. This work
demonstrates that tissue dynamics can regulate cellular infiltration.

text: Ribosomal defects perturb stem cell differentiation, causing diseases called
ribosomopathies. How ribosome levels control stem cell differentiation is not
fully known. Here, we discovered three RNA helicases are required for ribosome
biogenesis and for Drosophila oogenesis. Loss of these helicases, which we named
Aramis, Athos and Porthos, lead to aberrant stabilization of p53, cell cycle arrest
and stalled GSC differentiation. Unexpectedly, Aramis is required for efficient
translation of a cohort of mRNAs containing a 5’-Terminal-Oligo-Pyrimidine (TOP)-motif,
including mRNAs that encode ribosomal proteins and a conserved p53 inhibitor,
Novel Nucleolar protein 1 (Non1). The TOP-motif co-regulates the translation of
growth-related mRNAs in mammals. As in mammals, the La-related protein co-regulates
the translation of TOP-motif containing RNAs during Drosophila oogenesis. Thus,
a previously unappreciated TOP-motif in Drosophila responds to reduced ribosome
biogenesis to co-regulate the translation of ribosomal proteins and a p53 repressor,
thus coupling ribosome biogenesis to GSC differentiation.

text: Much of what we know about the role of auxin in plant development derives
from exogenous manipulations of auxin distribution and signaling, using inhibitors,
auxins and auxin analogs. In this context, synthetic auxin analogs, such as 1-Naphtalene
Acetic Acid (1-NAA), are often favored over the endogenous auxin indole-3-acetic
acid (IAA), in part due to their higher stability. While such auxin analogs have
proven to be instrumental to reveal the various faces of auxin, they display in
some cases distinct bioactivities compared to IAA. Here, we focused on the effect
of auxin analogs on the accumulation of PIN proteins in Brefeldin A-sensitive
endosomal aggregations (BFA bodies), and the correlation with the ability to elicit
Ca 2+ responses. For a set of commonly used auxin analogs, we evaluated if auxin-analog
induced Ca 2+ signaling inhibits PIN accumulation. Not all auxin analogs elicited
a Ca 2+ response, and their differential ability to elicit Ca 2+ responses correlated
partially with their ability to inhibit BFA-body formation. However, in tir1/afb
and cngc14, 1-NAA-induced Ca 2+ signaling was strongly impaired, yet 1-NAA still
could inhibit PIN accumulation in BFA bodies. This demonstrates that TIR1/AFB-CNGC14-dependent
Ca 2+ signaling does not inhibit BFA body formation in Arabidopsis roots.

text: Auxin, one of the first identified and most widely studied phytohormones,
has been and will remain a hot topic in plant biology. After more than a century
of passionate exploration, the mysteries of its synthesis, transport, signaling,
and metabolism have largely been unlocked. Due to the rapid development of new
technologies, new methods, and new genetic materials, the study of auxin has entered
the fast lane over the past 30 years. Here, we highlight advances in understanding
auxin signaling, including auxin perception, rapid auxin responses, TRANSPORT
INHIBITOR RESPONSE 1 and AUXIN SIGNALING F-boxes (TIR1/AFBs)-mediated transcriptional
and non-transcriptional branches, and the epigenetic regulation of auxin signaling.
We also focus on feedback inhibition mechanisms that prevent the over-amplification
of auxin signals. In addition, we cover the TRANSMEMBRANE KINASEs (TMKs)-mediated
non-canonical signaling, which converges with TIR1/AFBs-mediated transcriptional
regulation to coordinate plant growth and development. The identification of additional
auxin signaling components and their regulation will continue to open new avenues
of research in this field, leading to an increasingly deeper, more comprehensive
understanding of how auxin signals are interpreted at the cellular level to regulate
plant growth and development.

text: "Social insects are a common model to study disease dynamics in social animals.
Even though pathogens should thrive in social insect colonies as the hosts engage
in frequent social interactions, are closely related and live in a pathogen-rich
environment, disease outbreaks are rare. This is because social insects have evolved
mechanisms to keep pathogens at bay – and fight disease as a collective. Social
insect colonies are often viewed as “superorganisms” with division of labor between
reproductive “germ-like” queens and males and “somatic” workers, which together
form an interdependent reproductive unit that parallels a multicellular body.
Superorganisms possess a “social immune system” that comprises of collective disease
defenses performed by the workers - summarized as “social immunity”. In social
groups immunization (reduced susceptibility to a parasite upon secondary exposure
to the same parasite) can e.g. be triggered by social interactions (“social immunization”).
Social immunization can be caused by (i) asymptomatic low-level infections that
are acquired during caregiving to a contagious individual that can give an immune
boost, which can induce protection upon later encounter with the same pathogen
(active immunization) or (ii) by transfer of immune effectors between individuals
(passive immunization).\r\nIn the second chapter, I built up on a study that I
co-authored that found that low-level infections can not only be protective, but
also be costly and make the host more susceptible to detrimental superinfections
after contact to a very dissimilar pathogen. I here now tested different degrees
of phylogenetically-distant fungal strains of M. brunneum and M. robertsii in
L. neglectus and can describe the occurrence of cross-protection of social immunization
if the first and second pathogen are from the same level. Interestingly, low-level
infections only provided protection when the first strain was less virulent than
the second strain and elicited higher immune gene expression.\r\nIn the third
and fourth chapters, I expanded on the role of social immunity in sexual selection,
a so far unstudied field. I used the fungus Metarhizium robertsii and the ant
Cardiocondyla obscurior as a model, as in this species mating occurs in the presence
of workers and can be studied under laboratory conditions. Before males mate with
virgin queens in the nest they engage in fierce combat over the access to their
mating partners.\r\nFirst, I focused on male-male competition in the third chapter
and found that fighting with a contagious male is costly as it can lead to contamination
of the rival, but that workers can decrease the risk of disease contraction by
performing sanitary care.\r\nIn the fourth chapter, I studied the effect of fungal
infection on survival and mating success of sexuals (freshly emerged queens and
males) and found that worker-performed sanitary care can buffer the negative effect
that a pathogenic contagion would have on sexuals by spore removal from the exposed
individuals. When social immunity was prevented and queens could contract spores
from their mating partner, very low dosages led to negative consequences: their
lifespan was reduced and they produced fewer offspring with poor immunocompetence
compared to healthy queens. Interestingly, cohabitation with a late-stage infected
male where no spore transfer was possible had a positive effect on offspring immunity
– male offspring of mothers that apparently perceived an infected partner in their
vicinity reacted more sensitively to fungal challenge than male offspring without
paternal pathogen history."

text: Motivated by COVID-19, we develop and analyze a simple stochastic model for
the spread of disease in human population. We track how the number of infected
and critically ill people develops over time in order to estimate the demand that
is imposed on the hospital system. To keep this demand under control, we consider
a class of simple policies for slowing down and reopening society and we compare
their efficiency in mitigating the spread of the virus from several different
points of view. We find that in order to avoid overwhelming of the hospital system,
a policy must impose a harsh lockdown or it must react swiftly (or both). While
reacting swiftly is universally beneficial, being harsh pays off only when the
country is patient about reopening and when the neighboring countries coordinate
their mitigation efforts. Our work highlights the importance of acting decisively
when closing down and the importance of patience and coordination between neighboring
countries when reopening.

text: We compute the deterministic approximation of products of Sobolev functions
of large Wigner matrices W and provide an optimal error bound on their fluctuation

polynomials to general Sobolev functions, as well as from tracial quantities to
individual matrix elements. Applying the result to eitW for large t, we obtain
a precise decay rate for the overlaps of several deterministic matrices with temporally
well separated Heisenberg time evolutions; thus we demonstrate the thermalisation
effect of the unitary group generated by Wigner matrices.

text: 'When a cylindrical object penetrates granular matter near a vertical boundary,
it experiences two effects: its center of mass moves horizontally away from the
wall, and it rotates around its symmetry axis. Here we show experimentally that,
if two identical intruders instead of one are released side-by-side near the wall,
both effects are also detected. However, unexpected phenomena appear due to a
cooperative dynamics between the intruders. The net horizontal distance traveled
by the common center of mass of the twin intruders is much larger than that traveled
by one intruder released at the same initial distance from the wall, and the rotation
is also larger. The experimental results are well described by the Discrete Element
Method (DEM), which reveals that, as the number of intruders horizontally released
side-by-side increases, the total energy dissipation per intruder decreases. Finally,
DEM simulations demonstrate that the horizontal repulsion is substantially enhanced
if groups of intruders are released forming a column near the wall.'

text: Magnetic anisotropy in strontium iridate (Sr2IrO4) is essential because of
its strong spin–orbit coupling and crystal field effect. In this paper, we present
a detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for
different sample orientations using torque magnetometry measurements in the low-magnetic-field
region before the isospins are completely ordered. Dominant in-plane anisotropy
was identified at low fields, confirming the b axis as an easy magnetization axis.
Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed
that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange
interaction affecting the OOP interaction. The effect of interlayer exchange interaction
results in additional anisotropic terms owing to the tilting of the isospins.
The results are relevant for understanding OOP magnetic anisotropy and provide
a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic
exchange interactions. This study provides insight into the understanding of bulk
magnetic, magnetotransport, and spintronic behavior on Sr2IrO4 for future studies.

text: Predicting function from sequence is a central problem of biology. Currently,
this is possible only locally in a narrow mutational neighborhood around a wildtype
sequence rather than globally from any sequence. Using random mutant libraries,
we developed a biophysical model that accounts for multiple features of σ70 binding
bacterial promoters to predict constitutive gene expression levels from any sequence.
We experimentally and theoretically estimated that 10–20% of random sequences
lead to expression and ~80% of non-expressing sequences are one mutation away
from a functional promoter. The potential for generating expression from random
sequences is so pervasive that selection acts against σ70-RNA polymerase binding
sites even within inter-genic, promoter-containing regions. This pervasiveness
of σ70-binding sites implies that emergence of promoters is not the limiting step
in gene regulatory evolution. Ultimately, the inclusion of novel features of promoter
function into a mechanistic model enabled not only more accurate predictions of
gene expression levels, but also identified that promoters evolve more rapidly
than previously thought.

text: We consider two models for the sequence labeling (tagging) problem. The first
one is a Pattern-Based Conditional Random Field (PB), in which the energy of a
string (chain labeling) x=x1…xn∈Dn is a sum of terms over intervals [i,j] where
each term is non-zero only if the substring xi…xj equals a prespecified word
w∈Λ. The second model is a Weighted Context-Free Grammar (WCFG) frequently used
for natural language processing. PB and WCFG encode local and non-local interactions
respectively, and thus can be viewed as complementary. We propose a Grammatical
Pattern-Based CRF model (GPB) that combines the two in a natural way. We argue
that it has certain advantages over existing approaches such as the Hybrid model
of Benedí and Sanchez that combines N-grams and WCFGs. The focus of this paper
is to analyze the complexity of inference tasks in a GPB such as computing MAP.
We present a polynomial-time algorithm for general GPBs and a faster version for
a special case that we call Interaction Grammars.

text: 'The digitalization of almost all aspects of our everyday lives has led to
unprecedented amounts of data being freely available on the Internet. In particular
social media platforms provide rich sources of user-generated data, though typically
in unstructured form, and with high diversity, such as written in many different
languages. Automatically identifying meaningful information in such big data resources
and extracting it efficiently is one of the ongoing challenges of our time. A
common step for this is sentiment analysis, which forms the foundation for tasks
such as opinion mining or trend prediction. Unfortunately, publicly available
tools for this task are almost exclusively available for English-language texts.
Consequently, a large fraction of the Internet users, who do not communicate in
English, are ignored in automatized studies, a phenomenon called rare-language
discrimination.In this work we propose a technique to overcome this problem by
a truly multi-lingual model, which can be trained automatically without linguistic
knowledge or even the ability to read the many target languages. The main step
is to combine self-annotation, specifically the use of emoticons as a proxy for
labels, with multi-lingual sentence representations.To evaluate our method we
curated several large datasets from data obtained via the free Twitter streaming
API. The results show that our proposed multi-lingual training is able to achieve
sentiment predictions at the same quality level for rare languages as for frequent
ones, and in particular clearly better than what mono-lingual training achieves
on the same data. '

text: Targeting dysregulated Ca2+ signaling in cancer cells is an emerging chemotherapy
approach. We previously reported that store-operated Ca2+ entry (SOCE) blockers,
such as RP4010, are promising antitumor drugs for esophageal cancer. As a tyrosine
kinase inhibitor (TKI), afatinib received FDA approval to be used in targeted
therapy for patients with EGFR mutation-positive cancers. While preclinical studies
and clinical trials have shown that afatinib has benefits for esophageal cancer
patients, it is not known whether a combination of afatinib and RP4010 could achieve
better anticancer effects. Since TKI can alter intracellular Ca2+ dynamics through
EGFR/phospholipase C-γ pathway, in this study, we evaluated the inhibitory effect
of afatinib and RP4010 on intracellular Ca2+ oscillations in KYSE-150, a human
esophageal squamous cell carcinoma cell line, using both experimental and mathematical
simulations. Our mathematical simulation of Ca2+ oscillations could fit well with
experimental data responding to afatinib or RP4010, both separately or in combination.
Guided by simulation, we were able to identify a proper ratio of afatinib and
RP4010 for combined treatment, and such a combination presented synergistic anticancer-effect
evidence by experimental measurement of intracellular Ca2+ and cell proliferation.
This intracellular Ca2+ dynamic-based mathematical simulation approach could be
useful for a rapid and cost-effective evaluation of combined targeting therapy
drugs.

text: We provide a definition of the effective mass for the classical polaron described
by the Landau–Pekar (LP) equations. It is based on a novel variational principle,
minimizing the energy functional over states with given (initial) velocity. The
resulting formula for the polaron's effective mass agrees with the prediction
by LP (1948 J. Exp. Theor. Phys. 18 419–423).

text: 5-Carboxycytosine (5caC) is a rare epigenetic modification found in nucleic
acids of all domains of life. Despite its sparse genomic abundance, 5caC is presumed
to play essential regulatory roles in transcription, maintenance and base-excision
processes in DNA. In this work, we utilize nuclear magnetic resonance (NMR) spectroscopy
to address the effects of 5caC incorporation into canonical DNA strands at multiple
pH and temperature conditions. Our results demonstrate that 5caC has a pH-dependent
global destabilizing and a base-pair mobility enhancing local impact on dsDNA,
albeit without any detectable influence on the ground-state B-DNA structure. Measurement
of hybridization thermodynamics and kinetics of 5caC-bearing DNA duplexes highlighted
how acidic environment (pH 5.8 and 4.7) destabilizes the double-stranded structure
by ∼10–20 kJ mol–1 at 37 °C when compared to the same sample at neutral pH. Protonation
of 5caC results in a lower activation energy for the dissociation process and
a higher barrier for annealing. Studies on conformational exchange on the microsecond
time scale regime revealed a sharply localized base-pair motion involving exclusively
the modified site and its immediate surroundings. By direct comparison with canonical
and 5-formylcytosine (5fC)-edited strands, we were able to address the impact
of the two most oxidized naturally occurring cytosine derivatives in the genome.
These insights on 5caC’s subtle sensitivity to acidic pH contribute to the long-standing
questions of its capacity as a substrate in base excision repair processes and
its purpose as an independent, stable epigenetic mark.

text: In this Thesis, I study composite quantum impurities with variational techniques,
both inspired by machine learning as well as fully analytic. I supplement this
with exploration of other applications of machine learning, in particular artificial
neural networks, in many-body physics. In Chapters 3 and 4, I study quasiparticle
systems with variational approach. I derive a Hamiltonian describing the angulon
quasiparticle in the presence of a magnetic field. I apply analytic variational
treatment to this Hamiltonian. Then, I introduce a variational approach for non-additive
systems, based on artificial neural networks. I exemplify this approach on the
example of the polaron quasiparticle (Fröhlich Hamiltonian). In Chapter 5, I continue
using artificial neural networks, albeit in a different setting. I apply artificial
neural networks to detect phases from snapshots of two types physical systems.
Namely, I study Monte Carlo snapshots of multilayer classical spin models as well
as molecular dynamics maps of colloidal systems. The main type of networks that
I use here are convolutional neural networks, known for their applicability to
image data.

text: "AMPA-type glutamate receptors (AMPARs) mediate rapid signal transmission
at excitatory\r\nsynapses in the brain. Glutamate binding to the receptor’s ligand-binding
domains (LBDs)\r\nleads to ion channel activation and desensitization. Gating
kinetics shape synaptic transmission\r\nand are strongly modulated by transmembrane
AMPAR regulatory proteins (TARPs)\r\nthrough currently incompletely resolved mechanisms.
Here, electron cryo-microscopy\r\nstructures of the GluA1/2 TARP-γ8 complex, in
both open and desensitized states\r\n(at 3.5 Å), reveal state-selective engagement
of the LBDs by the large TARP-γ8 loop (‘β1’),\r\nelucidating how this TARP stabilizes
specific gating states. We further show how TARPs alter\r\nchannel rectification,
by interacting with the pore helix of the selectivity filter. Lastly, we\r\nreveal
that the Q/R-editing site couples the channel constriction at the filter entrance
to the\r\ngate, and forms the major cation binding site in the conduction path.
Our results provide a\r\nmechanistic framework of how TARPs modulate AMPAR gating
and conductance."

text: Presynaptic glutamate replenishment is fundamental to brain function. In high
activity regimes, such as epileptic episodes, this process is thought to rely
on the glutamate-glutamine cycle between neurons and astrocytes. However the presence
of an astroglial glutamine supply, as well as its functional relevance in vivo
in the healthy brain remain controversial, partly due to a lack of tools that
can directly examine glutamine transfer. Here, we generated a fluorescent probe
that tracks glutamine in live cells, which provides direct visual evidence of
an activity-dependent glutamine supply from astroglial networks to presynaptic
structures under physiological conditions. This mobilization is mediated by connexin43,
an astroglial protein with both gap-junction and hemichannel functions, and is
essential for synaptic transmission and object recognition memory. Our findings
uncover an indispensable recruitment of astroglial glutamine in physiological
synaptic activity and memory via an unconventional pathway, thus providing an
astrocyte basis for cognitive processes.

text: We establish the Hardy-Littlewood property (à la Borovoi-Rudnick) for Zariski
open subsets in affine quadrics of the form q(x1,...,xn)=m, where q is a non-degenerate
integral quadratic form in n>3 variables and m is a non-zero integer. This gives
asymptotic formulas for the density of integral points taking coprime polynomial
values, which is a quantitative version of the arithmetic purity of strong approximation
property off infinity for affine quadrics.
