text: "Recent substantial advances in the feld of superconducting circuits have
shown its\r\npotential as a leading platform for future quantum computing. In
contrast to classical\r\ncomputers based on bits that are represented by a single
binary value, 0 or 1, quantum\r\nbits (or qubits) can be in a superposition of
both. Thus, quantum computers can store\r\nand handle more information at the
same time and a quantum advantage has already\r\nbeen demonstrated for two types
of computational tasks. Rapid progress in academic\r\nand industry labs accelerates
the development of superconducting processors which may\r\nsoon fnd applications
in complex computations, chemical simulations, cryptography, and\r\noptimization.
Now that these machines are scaled up to tackle such problems the questions\r\nof
qubit interconnects and networks becomes very relevant. How to route signals on-chip\r\nbetween
diferent processor components? What is the most efcient way to entangle\r\nqubits?
And how to then send and process entangled signals between distant cryostats\r\nhosting
superconducting processors?\r\nIn this thesis, we are looking for solutions to
these problems by studying the collective\r\nbehavior of superconducting qubit
ensembles. We frst demonstrate on-demand tunable\r\ndirectional scattering of
microwave photons from a pair of qubits in a waveguide. Such a\r\ndevice can route
microwave photons on-chip with a high diode efciency. Then we focus\r\non studying
ultra-strong coupling regimes between light (microwave photons) and matter\r\n(superconducting
qubits), a regime that could be promising for extremely fast multi-qubit\r\nentanglement
generation. Finally, we show coherent pulse storage and periodic revivals\r\nin
a fve qubit ensemble strongly coupled to a resonator. Such a reconfgurable storage\r\ndevice
could be used as part of a quantum repeater that is needed for longer-distance\r\nquantum
communication.\r\nThe achieved high degree of control over multi-qubit ensembles
highlights not only the\r\nbeautiful physics of circuit quantum electrodynamics,
it also represents the frst step\r\ntoward new quantum simulation and communication
methods, and certain techniques\r\nmay also fnd applications in future superconducting
quantum computing hardware.\r\n"

text: "The infiltration of immune cells into tissues underlies the establishment
of tissue-resident\r\nmacrophages and responses to infections and tumors. However,
the mechanisms immune\r\ncells utilize to collectively migrate through tissue
barriers in vivo are not yet well understood.\r\nIn this thesis, I describe two
mechanisms that Drosophila immune cells (hemocytes) use to\r\novercome the tissue
barrier of the germband in the embryo. One strategy is the strengthening\r\nof
the actin cortex through developmentally controlled transcriptional regulation
induced by\r\nthe Drosophila proto-oncogene family member Dfos, which I show in
Chapter 2. Dfos induces\r\nexpression of the tetraspanin TM4SF and the filamin
Cher leading to higher levels of the\r\nactivated formin Dia at the cortex and
increased cortical F-actin. This enhanced cortical\r\nstrength allows hemocytes
to overcome the physical resistance of the surrounding tissue and\r\ntranslocate
their nucleus to move forward. This mechanism affects the speed of migration\r\nwhen
hemocytes face a confined environment in vivo.\r\nAnother aspect of the invasion
process is the initial step of the leading hemocytes entering\r\nthe tissue, which
potentially guides the follower cells. In Chapter 3, I describe a novel\r\nsubpopulation
of hemocytes activated by BMP signaling prior to tissue invasion that leads\r\npenetration
into the germband. Hemocytes that are deficient in BMP signaling activation\r\nshow
impaired persistence at the tissue entry, while their migration speed remains\r\nunaffected.\r\nThis
suggests that there might be different mechanisms controlling immune cell migration\r\nwithin
the confined environment in vivo, one of these being the general ability to overcome\r\nthe
resistance of the surrounding tissue and another affecting the order of hemocytes
that\r\ncollectively invade the tissue in a stream of individual cells.\r\nTogether,
my findings provide deeper insights into transcriptional changes in immune\r\ncells
that enable efficient tissue invasion and pave the way for future studies investigating
the\r\nearly colonization of tissues by macrophages in higher organisms. Moreover,
they extend the\r\ncurrent view of Drosophila immune cell heterogeneity and point
toward a potentially\r\nconserved role for canonical BMP signaling in specifying
immune cells that lead the migration\r\nof tissue resident macrophages during
embryogenesis."

text: Environmental cues influence the highly dynamic morphology of microglia. Strategies
to characterize these changes usually involve user-selected morphometric features,
which preclude the identification of a spectrum of context-dependent morphological
phenotypes. Here we develop MorphOMICs, a topological data analysis approach,
which enables semiautomatic mapping of microglial morphology into an atlas of
cue-dependent phenotypes and overcomes feature-selection biases and biological
variability. We extract spatially heterogeneous and sexually dimorphic morphological
phenotypes for seven adult mouse brain regions. This sex-specific phenotype declines
with maturation but increases over the disease trajectories in two neurodegeneration
mouse models, with females showing a faster morphological shift in affected brain
regions. Remarkably, microglia morphologies reflect an adaptation upon repeated
exposure to ketamine anesthesia and do not recover to control morphologies. Finally,
we demonstrate that both long primary processes and short terminal processes provide
distinct insights to morphological phenotypes. MorphOMICs opens a new perspective
to characterize microglial morphology.

text: 'When crawling through the body, leukocytes often traverse tissues that are
densely packed with extracellular matrix and other cells, and this raises the
question: How do leukocytes overcome compressive mechanical loads? Here, we show
that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness
requires neither force sensing via the nucleus nor adhesive interactions with
a substrate. Upon global compression of the cell body as well as local indentation
of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into
dot-like structures, providing activation platforms for Arp2/3 nucleated actin
patches. These patches locally push against the external load, which can be obstructing
collagen fibers or other cells, and thereby create space to facilitate forward
locomotion. We show in vitro and in vivo that this WASp function is rate limiting
for ameboid leukocyte migration in dense but not in loose environments and is
required for trafficking through diverse tissues such as skin and lymph nodes.'

text: "Environmental cues influence the highly dynamic morphology of microglia.
Strategies to \r\ncharacterize these changes usually involve user-selected morphometric
features, which \r\npreclude the identification of a spectrum of context-dependent
morphological phenotypes. \r\nHere, we develop MorphOMICs, a topological data
analysis approach, which enables semi\x02automatic mapping of microglial morphology
into an atlas of cue-dependent phenotypes,\r\novercomes feature-selection bias
and minimizes biological variability. \r\nFirst, with MorphOMICs we derive the
morphological spectrum of microglia across seven \r\nbrain regions during postnatal
development and in two distinct Alzheimer’s disease \r\ndegeneration mouse models.
We uncover region-specific and sexually dimorphic\r\nmorphological trajectories,
with females showing an earlier morphological shift than males in \r\nthe degenerating
brain. Overall, we demonstrate that both long primary- and short terminal \r\nprocesses
provide distinct insights to morphological phenotypes. Moreover, using machine
\r\nlearning to map novel condition on the spectrum, we observe that microglia
morphologies \r\nreflect a dose-dependent adaptation upon ketamine anesthesia
and do not recover to control \r\nmorphologies.\r\nNext, we took advantage of
MorphOMICs to build a high-resolution and layer-specific map of \r\nmicroglial
morphological spectrum in the retina, covering postnatal development and rd10
\r\ndegeneration. Here, following photoreceptor death, microglia assume an early
development\x02like morphology. Finally, we map microglial morphology following
optic nerve crush on the \r\nretinal spectrum and observe a layer- and sex-dependent
response. \r\nOverall, MorphOMICs opens a new perspective to analyze microglial
morphology across \r\nmultiple conditions, and provides a novel tool to characterize
microglial morphology beyond \r\nthe traditionally dichotomized view of microglia."

text: "In evolve and resequence experiments, a population is sequenced, subjected
to selection and\r\nthen sequenced again, so that genetic changes before and after
selection can be observed at\r\nthe genetic level. Here, I use these studies to
better understand the genetic basis of complex\r\ntraits - traits which depend
on more than a few genes.\r\nIn the first chapter, I discuss the first evolve
and resequence experiment, in which a population\r\nof mice, the so-called \"Longshanks\"
mice, were selected for tibia length while their body mass\r\nwas kept constant.
The full pedigree is known. We observed a selection response on all\r\nchromosomes
and used the infinitesimal model with linkage, a model which assumes an infinite\r\nnumber
of genes with infinitesimally small effect sizes, as a null model. Results implied
a very\r\npolygenic basis with a few loci of major effect standing out and changing
in parallel. There\r\nwas large variability between the different chromosomes
in this study, probably due to LD.\r\nIn chapter two, I go on to discuss the impact
of LD, on the variability in an allele-frequency\r\nbased summary statistic, giving
an equation based on the initial allele frequencies, average\r\npairwise LD, and
the first four moments of the haplotype block copy number distribution. I\r\ndescribe
this distribution by referring back to the founder generation. I then demonstrate\r\nhow
to infer selection via a maximum likelihood scheme on the example of a single
locus and\r\ndiscuss how to extend this to more realistic scenarios.\r\nIn chapter
three, I discuss the second evolve and resequence experiment, in which a small\r\npopulation
of Drosophila melanogaster was selected for increased pupal case size over 6\r\ngenerations.
The experiment was highly replicated with 27 lines selected within family and
a\r\nknown pedigree. We observed a phenotypic selection response of over one standard
deviation.\r\nI describe the patterns in allele frequency data, including allele
frequency changes and patterns\r\nof heterozygosity, and give ideas for future
work."

text: "Detachment of the cancer cells from the bulk of the tumor is the first step
of metastasis, which\r\nis the primary cause of cancer related deaths. It is unclear,
which factors contribute to this step.\r\nRecent studies indicate a crucial role
of the tumor microenvironment in malignant\r\ntransformation and metastasis. Studying
cancer cell invasion and detachments quantitatively in\r\nthe context of its physiological
microenvironment is technically challenging. Especially, precise\r\ncontrol of
microenvironmental properties in vivo is currently not possible. Here, I studied
the\r\nrole of microenvironment geometry in the invasion and detachment of cancer
cells from the\r\nbulk with a simplistic and reductionist approach. In this approach,
I engineered microfluidic\r\ndevices to mimic a pseudo 3D extracellular matrix
environment, where I was able to\r\nquantitatively tune the geometrical configuration
of the microenvironment and follow tumor\r\ncells with fluorescence live imaging.
To aid quantitative analysis I developed a widely applicable\r\nsoftware application
to automatically analyze and visualize particle tracking data.\r\nQuantitative
analysis of tumor cell invasion in isotropic and anisotropic microenvironments\r\nshowed
that heterogeneity in the microenvironment promotes faster invasion and more\r\nfrequent
detachment of cells. These observations correlated with overall higher speed of
cells at\r\nthe edge of the bulk of the cells. In heterogeneous microenvironments
cells preferentially\r\npassed through larger pores, thus invading areas of least
resistance and generating finger-like\r\ninvasive structures. The detachments
occurred mostly at the tips of these structures.\r\nTo investigate the potential
mechanism, we established a two dimensional model to simulate\r\nactive Brownian
particles representing the cell nuclei dynamics. These simulations backed our
in\r\nvitro observations without the need of precise fitting the simulation parameters.
Our model\r\nsuggests the importance of the pore heterogeneity in the direction
perpendicular to the\r\norientation of bias field (lateral heterogeneity), which
causes the interface roughening."

abstract:
- lang: eng
text: 'FtsA is crucial for assembly of the E. coli divisome, as it dynamically links
cytoplasmic FtsZ filaments with transmembrane cell division proteins. FtsA allegedly
initiates cell division by switching from an inactive polymeric to an active monomeric
confirmation, which recruits downstream proteins and stabilizes FtsZ filaments.
Here, we use biochemical reconstitution experiments combined with quantitative
fluorescence microscopy to study divisome activation in vitro. We compare wildtype-FtsA
with FtsA-R286W, a constantly active gain-of-function mutant and find that R286W
outperforms the wildtype protein in replicating FtsZ treadmilling dynamics, stabilizing
FtsZ filaments and recruiting FtsN. We attribute these differences to a faster
membrane exchange of FtsA-R286W and its higher packing density below FtsZ filaments. Using
FRET microscopy, we find that FtsN binding does not compete with, but promotes
FtsA self-interaction. Our findings suggest a model where FtsA always forms dynamic
polymers on the membrane, which re-organize during assembly and activation of
the divisome. '

abstract:
- lang: eng
text: The actin-homologue FtsA is essential for E. coli cell division, as it links
FtsZ filaments in the Z-ring to transmembrane proteins. FtsA is thought to initiate
cell constriction by switching from an inactive polymeric to an active monomeric
conformation, which recruits downstream proteins and stabilizes the Z-ring. However,
direct biochemical evidence for this mechanism is missing. Here, we use reconstitution
experiments and quantitative fluorescence microscopy to study divisome activation
in vitro. By comparing wild-type FtsA with FtsA R286W, we find that this hyperactive
mutant outperforms FtsA WT in replicating FtsZ treadmilling dynamics, FtsZ filament
stabilization and recruitment of FtsN. We could attribute these differences to
a faster exchange and denser packing of FtsA R286W below FtsZ filaments. Using
FRET microscopy, we also find that FtsN binding promotes FtsA self-interaction.
We propose that in the active divisome FtsA and FtsN exist as a dynamic copolymer
that follows treadmilling filaments of FtsZ.

text: 'Endocytosis is a multistep process involving the sequential recruitment and
action of numerous proteins. This process can be divided into two phases: an early
phase, in which sites of endocytosis are formed, and a late phase in which clathrin-coated
vesicles are formed and internalized into the cytosol, but how these phases link
to each other remains unclear. In this study, we demonstrate that anchoring the
yeast Eps15-like protein Pan1p to the peroxisome triggers most of the events occurring
during the late phase at the peroxisome. At this ectopic location, Pan1p recruits
most proteins that function in the late phases—including actin nucleation promoting
factors—and then initiates actin polymerization. Pan1p also recruited Prk1 kinase
and actin depolymerizing factors, thereby triggering disassembly immediately after
actin assembly and inducing dissociation of endocytic proteins from the peroxisome.
These observations suggest that Pan1p is a key regulator for initiating, processing,
and completing the late phase of endocytosis.'

text: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual
lineages of parthenogenetic females, which produce rare males at low frequencies.
Although they are known to have ZW chromosomes, these are not well characterized,
and it is unclear whether they are shared across the clade. Furthermore, the underlying
genetic architecture of the transmission of asexuality, which can occur when rare
males mate with closely related sexual females, is not well understood. We produced
a chromosome-level assembly for the sexual Eurasian species A. sinica and characterized
in detail the pair of sex chromosomes of this species. We combined this new assembly
with short-read genomic data for the sexual species A. sp. Kazakhstan and several
asexual lineages of A. parthenogenetica, allowing us to perform an in-depth characterization
of sex-chromosome evolution across the genus. We identified a small differentiated
region of the ZW pair that is shared by all sexual and asexual lineages, supporting
the shared ancestry of the sex chromosomes. We also inferred that recombination
suppression has spread to larger sections of the chromosome independently in the
American and Eurasian lineages. Finally, we took advantage of a rare male, which
we backcrossed to sexual females, to explore the genetic basis of asexuality.
Our results suggest that parthenogenesis is likely partly controlled by a locus
on the Z chromosome, highlighting the interplay between sex determination and
asexuality.

text: 'Complex I is the first enzyme in the respiratory chain, which is responsible
for energy production in mitochondria and bacteria1. Complex I couples the transfer
of two electrons from NADH to quinone and the translocation of four protons across
the membrane2, but the coupling mechanism remains contentious. Here we present
cryo-electron microscopy structures of Escherichia coli complex I (EcCI) in different
redox states, including catalytic turnover. EcCI exists mostly in the open state,
in which the quinone cavity is exposed to the cytosol, allowing access for water
molecules, which enable quinone movements. Unlike the mammalian paralogues3, EcCI
can convert to the closed state only during turnover, showing that closed and
open states are genuine turnover intermediates. The open-to-closed transition
results in the tightly engulfed quinone cavity being connected to the central
axis of the membrane arm, a source of substrate protons. Consistently, the proportion
of the closed state increases with increasing pH. We propose a detailed but straightforward
and robust mechanism comprising a ‘domino effect’ series of proton transfers and
electrostatic interactions: the forward wave (‘dominoes stacking’) primes the
pump, and the reverse wave (‘dominoes falling’) results in the ejection of all
pumped protons from the distal subunit NuoL. This mechanism explains why protons
exit exclusively from the NuoL subunit and is supported by our mutagenesis data.
We contend that this is a universal coupling mechanism of complex I and related
enzymes.'

text: 'Understanding the properties of neural networks trained via stochastic gradient
descent (SGD) is at the heart of the theory of deep learning. In this work, we
take a mean-field view, and consider a two-layer ReLU network trained via noisy-SGD
for a univariate regularized regression problem. Our main result is that SGD with
vanishingly small noise injected in the gradients is biased towards a simple solution:
at convergence, the ReLU network implements a piecewise linear map of the inputs,
and the number of “knot” points -- i.e., points where the tangent of the ReLU
network estimator changes -- between two consecutive training inputs is at most
three. In particular, as the number of neurons of the network grows, the SGD dynamics
is captured by the solution of a gradient flow and, at convergence, the distribution
of the weights approaches the unique minimizer of a related free energy, which
has a Gibbs form. Our key technical contribution consists in the analysis of the
estimator resulting from this minimizer: we show that its second derivative vanishes
everywhere, except at some specific locations which represent the “knot” points.
We also provide empirical evidence that knots at locations distinct from the data
points might occur, as predicted by our theory.'

text: "The ability to form and retrieve memories is central to survival. In mammals,
the hippocampus\r\nis a brain region essential to the acquisition and consolidation
of new memories. It is also\r\ninvolved in keeping track of one’s position in
space and aids navigation. Although this\r\nspace-memory has been a source of
contradiction, evidence supports the view that the role of\r\nthe hippocampus
in navigation is memory, thanks to the formation of cognitive maps. First\r\nintroduced
by Tolman in 1948, cognitive maps are generally used to organize experiences in\r\nmemory;
however, the detailed mechanisms by which these maps are formed and stored are
not\r\nyet agreed upon. Some influential theories describe this process as involving
three fundamental\r\nsteps: initial encoding by the hippocampus, interactions
between the hippocampus and other\r\ncortical areas, and long-term extra-hippocampal
consolidation. In this thesis, I will show how\r\nthe investigation of cognitive
maps of space helped to shed light on each of these three memory\r\nprocesses.\r\nThe
first study included in this thesis deals with the initial encoding of spatial
memories in\r\nthe hippocampus. Much is known about encoding at the level of single
cells, but less about\r\ntheir co-activity or joint contribution to the encoding
of novel spatial information. I will\r\ndescribe the structure of an interaction
network that allows for efficient encoding of noisy\r\nspatial information during
the first exploration of a novel environment.\r\nThe second study describes the
interactions between the hippocampus and the prefrontal\r\ncortex (PFC), two areas
directly and indirectly connected. It is known that the PFC, in concert\r\nwith
the hippocampus, is involved in various processes, including memory storage and
spatial\r\nnavigation. Nonetheless, the detailed mechanisms by which PFC receives
information from the\r\nhippocampus are not clear. I will show how a transient
improvement in theta phase locking of\r\nPFC cells enables interactions of cell
pairs across the two regions.\r\nThe third study describes the learning of behaviorally-relevant
spatial locations in the hippocampus and the medial entorhinal cortex. I will
show how the accumulation of firing around\r\ngoal locations, a correlate of learning,
can shed light on the transition from short- to long-term\r\nspatial memories
and the speed of consolidation in different brain areas.\r\nThe studies included
in this thesis represent the main scientific contributions of my Ph.D. They\r\ninvolve
statistical analyses and models of neural responses of cells in different brain
areas of\r\nrats executing spatial tasks. I will conclude the thesis by discussing
the impact of the findings\r\non principles of memory formation and retention,
including the mechanisms, the speed, and\r\nthe duration of these processes."

text: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual
lineages of parthenogenetic females, which produce rare males at low frequencies.
Although they are known to have ZW chromosomes, these are not well characterized,
and it is unclear whether they are shared across the clade. Furthermore, the underlying
genetic architecture of the transmission of asexuality, which can occur when rare
males mate with closely related sexual females, is not well understood. We produced
a chromosome-level assembly for the sexual Eurasian species Artemia sinica and
characterized in detail the pair of sex chromosomes of this species. We combined
this new assembly with short-read genomic data for the sexual species Artemia
sp. Kazakhstan and several asexual lineages of Artemia parthenogenetica, allowing
us to perform an in-depth characterization of sex-chromosome evolution across
the genus. We identified a small differentiated region of the ZW pair that is
shared by all sexual and asexual lineages, supporting the shared ancestry of the
sex chromosomes. We also inferred that recombination suppression has spread to
larger sections of the chromosome independently in the American and Eurasian lineages.
Finally, we took advantage of a rare male, which we backcrossed to sexual females,
to explore the genetic basis of asexuality. Our results suggest that parthenogenesis
is likely partly controlled by a locus on the Z chromosome, highlighting the interplay
between sex determination and asexuality.

text: The t-haplotype of mice is a classical model for autosomal transmission distortion.
A largely non-recombining variant of the proximal region of chromosome 17, it
is transmitted to more than 90% of the progeny of heterozygous males through the
disabling of sperm carrying a standard chromosome. While extensive genetic and
functional work has shed light on individual genes involved in drive, much less
is known about the evolution and function of the rest of its hundreds of genes.
Here, we characterize the sequence and expression of dozens of t-specific transcripts
and of their chromosome 17 homologues. Many genes showed reduced expression of
the t-allele, but an equal number of genes showed increased expression of their
t-copy, consistent with increased activity or a newly evolved function. Genes
on the t-haplotype had a significantly higher non-synonymous substitution rate
than their homologues on the standard chromosome, with several genes harbouring
dN/dS ratios above 1. Finally, the t-haplotype has acquired at least two genes
from other chromosomes, which show high and tissue-specific expression. These
results provide a first overview of the gene content of this selfish element,
and support a more dynamic evolutionary scenario than expected of a large genomic
region with almost no recombination.

text: Solid-state microwave systems offer strong interactions for fast quantum logic
and sensing but photons at telecom wavelength are the ideal choice for high-density
low-loss quantum interconnects. A general-purpose interface that can make use
of single photon effects requires < 1 input noise quanta, which has remained elusive
due to either low efficiency or pump induced heating. Here we demonstrate coherent
electro-optic modulation on nanosecond-timescales with only 0.16+0.02−0.01 microwave
input noise photons with a total bidirectional transduction efficiency of 8.7%
(or up to 15% with 0.41+0.02−0.02), as required for near-term heralded quantum
network protocols. The use of short and high-power optical pump pulses also enables
near-unity cooperativity of the electro-optic interaction leading to an internal
pure conversion efficiency of up to 99.5%. Together with the low mode occupancy
this provides evidence for electro-optic laser cooling and vacuum amplification
as predicted a decade ago.

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: It is practical to collect a huge amount of movement data and environmental
context information along with the health signals of individuals because there
is the emergence of new generations of positioning and tracking technologies and
rapid advancements of health sensors. The study of the relations between these
datasets and their sequence similarity analysis is of interest to many applications
such as health monitoring and recommender systems. However, entering all movement
parameters and health signals can lead to the complexity of the problem and an
increase in its computational load. In this situation, dimension reduction techniques
can be used to avoid consideration of simultaneous dependent parameters in the
process of similarity measurement of the trajectories. The present study provides
a framework, named CaDRAW, to use spatial–temporal data and movement parameters
along with independent context information in the process of measuring the similarity
of trajectories. In this regard, the omission of dependent movement characteristic
signals is conducted by using an unsupervised feature selection dimension reduction
technique. To evaluate the effectiveness of the proposed framework, it was applied
to a real contextualized movement and related health signal datasets of individuals.
The results indicated the capability of the proposed framework in measuring the
similarity and in decreasing the characteristic signals in such a way that the
similarity results -before and after reduction of dependent characteristic signals-
have small differences. The mean differences between the obtained results before
and after reducing the dimension were 0.029 and 0.023 for the round path, respectively.
