  text: Mutations in the chromodomain helicase DNA-binding 8 (CHD8) gene are a frequent
    cause of autism spectrum disorder (ASD). While its phenotypic spectrum often encompasses
    macrocephaly, implicating cortical abnormalities, how CHD8 haploinsufficiency
    affects neurodevelopmental is unclear. Here, employing human cerebral organoids,
    we find that CHD8 haploinsufficiency disrupted neurodevelopmental trajectories
    with an accelerated and delayed generation of, respectively, inhibitory and excitatory
    neurons that yields, at days 60 and 120, symmetrically opposite expansions in
    their proportions. This imbalance is consistent with an enlargement of cerebral
    organoids as an in vitro correlate of patients’ macrocephaly. Through an isogenic
    design of patient-specific mutations and mosaic organoids, we define genotype-phenotype
    relationships and uncover their cell-autonomous nature. Our results define cell-type-specific
    CHD8-dependent molecular defects related to an abnormal program of proliferation
    and alternative splicing. By identifying cell-type-specific effects of CHD8 mutations,
    our study uncovers reproducible developmental alterations that may be employed
    for neurodevelopmental disease modeling.

  text: "Autism spectrum disorders (ASDs) are a group of neurodevelopmental disorders
    character\x02ized by behavioral symptoms such as problems in social communication
    and interaction, as\r\nwell as repetitive, restricted behaviors and interests.
    These disorders show a high degree\r\nof heritability and hundreds of risk genes
    have been identifed using high throughput\r\nsequencing technologies. This genetic
    heterogeneity has hampered eforts in understanding\r\nthe pathogenesis of ASD
    but at the same time given rise to the concept of convergent\r\nmechanisms. Previous
    studies have identifed that risk genes for ASD broadly converge\r\nonto specifc
    functional categories with transcriptional regulation being one of the biggest\r\ngroups.
    In this thesis, I focus on this subgroup of genes and investigate the gene regulatory\r\nconsequences
    of some of them in the context of neurodevelopment.\r\nFirst, we showed that mutations
    in the ASD and intellectual disability risk gene Setd5 lead\r\nto perturbations
    of gene regulatory programs in early cell fate specifcation. In addition,\r\nadult
    animals display abnormal learning behavior which is mirrored at the transcriptional\r\nlevel
    by altered activity dependent regulation of postsynaptic gene expression. Lastly,\r\nwe
    link the regulatory function of Setd5 to its interaction with the Paf1 and the
    NCoR\r\ncomplex.\r\nSecond, by modeling the heterozygous loss of the top ASD gene
    CHD8 in human cerebral\r\norganoids we demonstrate profound changes in the developmental
    trajectories of both\r\ninhibitory and excitatory neurons using single cell RNA-sequencing.
    While the former\r\nwere generated earlier in CHD8+/- organoids, the generation
    of the latter was shifted to\r\nlater times in favor of a prolonged progenitor
    expansion phase and ultimately increased\r\norganoid size.\r\nFinally, by modeling
    heterozygous mutations for four ASD associated chromatin modifers,\r\nASH1L, KDM6B,
    KMT5B, and SETD5 in human cortical spheroids we show evidence of\r\nregulatory
    convergence across three of those genes. We observe a shift from dorsal cortical\r\nexcitatory
    neuron fates towards partially ventralized cell types resembling cells from the\r\nlateral
    ganglionic eminence. As this project is still ongoing at the time of writing,
    future\r\nexperiments will aim at elucidating the regulatory mechanisms underlying
    this shift with\r\nthe aim of linking these three ASD risk genes through biological
    convergence."

  text: 'The infiltration of immune cells into tissues underlies the establishment
    of tissue-resident macrophages and responses to infections and tumors. Yet the
    mechanisms immune cells utilize to negotiate tissue barriers in living organisms
    are not well understood, and a role for cortical actin has not been examined.
    Here, we find that the tissue invasion of Drosophila macrophages, also known as
    plasmatocytes or hemocytes, utilizes enhanced cortical F-actin levels stimulated
    by the Drosophila member of the fos proto oncogene transcription factor family
    (Dfos, Kayak). RNA sequencing analysis and live imaging show that Dfos enhances
    F-actin levels around the entire macrophage surface by increasing mRNA levels
    of the membrane spanning molecular scaffold tetraspanin TM4SF, and the actin cross-linking
    filamin Cheerio, which are themselves required for invasion. Both the filamin
    and the tetraspanin enhance the cortical activity of Rho1 and the formin Diaphanous
    and thus the assembly of cortical actin, which is a critical function since expressing
    a dominant active form of Diaphanous can rescue the Dfos macrophage invasion defect.
    In vivo imaging shows that Dfos enhances the efficiency of the initial phases
    of macrophage tissue entry. Genetic evidence argues that this Dfos-induced program
    in macrophages counteracts the constraint produced by the tension of surrounding
    tissues and buffers the properties of the macrophage nucleus from affecting tissue
    entry. We thus identify strengthening the cortical actin cytoskeleton through
    Dfos as a key process allowing efficient forward movement of an immune cell into
    surrounding tissues. '

  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: "AMPA receptors (AMPARs) mediate fast excitatory neurotransmission and their
    role is\r\nimplicated in complex processes such as learning and memory and various
    neurological\r\ndiseases. These receptors are composed of different subunits and
    the subunit composition can\r\naffect channel properties, receptor trafficking
    and interaction with other associated proteins.\r\nUsing the high sensitivity
    SDS-digested freeze-fracture replica labeling (SDS-FRL) for\r\nelectron microscopy
    I investigated the number, density, and localization of AMPAR subunits,\r\nGluA1,
    GluA2, GluA3, and GluA1-3 (panAMPA) in pyramidal cells in the CA1 area of mouse\r\nhippocampus.
    I have found that the immunogold labeling for all of these subunits in the\r\npostsynaptic
    sites was highest in stratum radiatum and lowest in stratum lacunosummoleculare.
    The labeling density for the all subunits in the extrasynaptic sites showed a
    gradual\r\nincrease from the pyramidal cell soma towards the distal part of stratum
    radiatum. The densities\r\nof extrasynaptic GluA1, GluA2 and panAMPA labeling
    reached 10-15% of synaptic densities,\r\nwhile the ratio of extrasynaptic labeling
    for GluA3 was significantly lower compared than those\r\nfor other subunits. The
    labeling patterns for GluA1, GluA2 and GluA1-3 are similar and their\r\ndensities
    were higher in the periphery than center of synapses. In contrast, the GluA3-\r\ncontaining
    receptors were more centrally localized compared to the GluA1- and GluA2-\r\ncontaining
    receptors.\r\nThe hippocampus plays a central role in learning and memory. Contextual
    learning has been\r\nshown to require the delivery of AMPA receptors to CA1 synapses
    in the dorsal hippocampus.\r\nHowever, proximodistal heterogeneity of this plasticity
    and particular contribution of different\r\nAMPA receptor subunits are not fully
    understood. By combining inhibitory avoidance task, a\r\nhippocampus-dependent
    contextual fear-learning paradigm, with SDS-FRL, I have revealed an\r\nincrease
    in synaptic density specific to GluA1-containing AMPA receptors in the CA1 area.\r\nThe
    intrasynaptic distribution of GluA1 also changed from the periphery to center-preferred\r\npattern.
    Furthermore, this synaptic plasticity was evident selectively in stratum radiatum
    but\r\nnot stratum oriens, and in the CA1 subregion proximal but not distal to
    CA2. These findings\r\nfurther contribute to our understanding of how specific
    hippocampal subregions and AMPA\r\nreceptor subunits are involved in physiological
    learning.\r\nAlthough the immunolabeling results above shed light on subunit-specific
    plasticity in\r\nAMPAR distribution, no tools to visualize and study the subunit
    composition at the single\r\nchannel level in situ have been available. Electron
    microscopy with conventional immunogold\r\nlabeling approaches has limitations
    in the single channel analysis because of the large size of\r\nantibodies and
    steric hindrance hampering multiple subunit labeling of single channels. I\r\nmanaged
    to develop a new chemical labeling system using a short peptide tag and small\r\nsynthetic
    probes, which form specific covalent bond with a cysteine residue in the tag fused
    to\r\nproteins of interest (reactive tag system). I additionally made substantial
    progress into adapting\r\nthis system for AMPA receptor subunits."

  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

  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: "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

  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: '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: "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."

  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: "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: 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.

  text: Weak convergence of inertial iterative method for solving variational inequalities
    is the focus of this paper. The cost function is assumed to be non-Lipschitz and
    monotone. We propose a projection-type method with inertial terms and give weak
    convergence analysis under appropriate conditions. Some test results are performed
    and compared with relevant methods in the literature to show the efficiency and
    advantages given by our proposed methods.
