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

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

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

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

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

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

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

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

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

  text: We consider the problem of learning a Bayesian network or directed acyclic
    graph model from observational data. A number of constraint‐based, score‐based
    and hybrid algorithms have been developed for this purpose. Statistical consistency
    guarantees of these algorithms rely on the faithfulness assumption, which has
    been shown to be restrictive especially for graphs with cycles in the skeleton.
    We here propose the sparsest permutation (SP) algorithm, showing that learning
    Bayesian networks is possible under strictly weaker assumptions than faithfulness.
    This comes at a computational price, thereby indicating a statistical‐computational
    trade‐off for causal inference algorithms. In the Gaussian noiseless setting,
    we prove that the SP algorithm boils down to finding the permutation of the variables
    with the sparsest Cholesky decomposition of the inverse covariance matrix, which
    is equivalent to ℓ0‐penalized maximum likelihood estimation. We end with a simulation
    study showing that in line with the proven stronger consistency guarantees, and
    the SP algorithm compares favourably to standard causal inference algorithms in
    terms of accuracy for a given sample size.

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

  text: Parvalbumin-positive (PV+) GABAergic interneurons in hippocampal microcircuits
    are thought to play a key role in several higher network functions, such as feedforward
    and feedback inhibition, network oscillations, and pattern separation. Fast lateral
    inhibition mediated by GABAergic interneurons may implement a winner-takes-all
    mechanism in the hippocampal input layer. However, it is not clear whether the
    functional connectivity rules of granule cells (GCs) and interneurons in the dentate
    gyrus are consistent with such a mechanism. Using simultaneous patch-clamp recordings
    from up to seven GCs and up to four PV+ interneurons in the dentate gyrus, we
    find that connectivity is structured in space, synapse-specific, and enriched
    in specific disynaptic motifs. In contrast to the neocortex, lateral inhibition
    in the dentate gyrus (in which a GC inhibits neighboring GCs via a PV+ interneuron)
    is ~ 10-times more abundant than recurrent inhibition (in which a GC inhibits
    itself). Thus, unique connectivity rules may enable the dentate gyrus to perform
    specific higher-order computations

  text: Conventional ultra-high sensitivity detectors in the millimeter-wave range
    are usually cooled as their own thermal noise at room temperature would mask the
    weak received radiation. The need for cryogenic systems increases the cost and
    complexity of the instruments, hindering the development of, among others, airborne
    and space applications. In this work, the nonlinear parametric upconversion of
    millimeter-wave radiation to the optical domain inside high-quality (Q) lithium
    niobate whispering-gallery mode (WGM) resonators is proposed for ultra-low noise
    detection. We experimentally demonstrate coherent upconversion of millimeter-wave
    signals to a 1550 nm telecom carrier, with a photon conversion efficiency surpassing
    the state-of-the-art by 2 orders of magnitude. Moreover, a theoretical model shows
    that the thermal equilibrium of counterpropagating WGMs is broken by overcoupling
    the millimeter-wave WGM, effectively cooling the upconverted mode and allowing
    ultra-low noise detection. By theoretically estimating the sensitivity of a correlation
    radiometer based on the presented scheme, it is found that room-temperature radiometers
    with better sensitivity than state-of-the-art high-electron-mobility transistor
    (HEMT)-based radiometers can be designed. This detection paradigm can be used
    to develop room-temperature instrumentation for radio astronomy, earth observation,
    planetary missions, and imaging systems.

  text: The strong atomistic spin–orbit coupling of holes makes single-shot spin readout
    measurements difficult because it reduces the spin lifetimes. By integrating the
    charge sensor into a high bandwidth radio frequency reflectometry setup, we were
    able to demonstrate single-shot readout of a germanium quantum dot hole spin and
    measure the spin lifetime. Hole spin relaxation times of about 90 μs at 500 mT
    are reported, with a total readout visibility of about 70%. By analyzing separately
    the spin-to-charge conversion and charge readout fidelities, we have obtained
    insight into the processes limiting the visibilities of hole spins. The analyses
    suggest that high hole visibilities are feasible at realistic experimental conditions,
    underlying the potential of hole spins for the realization of viable qubit devices.

  text: Partially-observable Markov decision processes (POMDPs) with discounted-sum
    payoff are a standard framework to model a wide range of problems related to decision
    making under uncertainty. Traditionally, the goal has been to obtain policies
    that optimize the expectation of the discounted-sum payoff. A key drawback of
    the expectation measure is that even low probability events with extreme payoff
    can significantly affect the expectation, and thus the obtained policies are not
    necessarily risk-averse. An alternate approach is to optimize the probability
    that the payoff is above a certain threshold, which allows obtaining risk-averse
    policies, but ignores optimization of the expectation. We consider the expectation
    optimization with probabilistic guarantee (EOPG) problem, where the goal is to
    optimize the expectation ensuring that the payoff is above a given threshold with
    at least a specified probability. We present several results on the EOPG problem,
    including the first algorithm to solve it.

  text: Reed-Muller (RM) and polar codes are a class of capacity-achieving channel
    coding schemes with the same factor graph representation. Low-complexity decoding
    algorithms fall short in providing a good error-correction performance for RM
    and polar codes. Using the symmetric group of RM and polar codes, the specific
    decoding algorithm can be carried out on multiple permutations of the factor graph
    to boost the error-correction performance. However, this approach results in high
    decoding complexity. In this paper, we first derive the total number of factor
    graph permutations on which the decoding can be performed. We further propose
    a successive permutation (SP) scheme which finds the permutations on the fly,
    thus the decoding always progresses on a single factor graph permutation. We show
    that SP can be used to improve the error-correction performance of RM and polar
    codes under successive-cancellation (SC) and SC list (SCL) decoding, while keeping
    the memory requirements of the decoders unaltered. Our results for RM and polar
    codes of length 128 and rate 0.5 show that when SP is used and at a target frame
    error rate of 10 -4 , up to 0.5 dB and 0.1 dB improvement can be achieved for
    RM and polar codes respectively.

  text: We prove that, at least for the binary erasure channel, the polar-coding paradigm
    gives rise to codes that not only approach the Shannon limit but, in fact, do
    so under the best possible scaling of their block length as a function of the
    gap to capacity. This result exhibits the first known family of binary codes that
    attain both optimal scaling and quasi-linear complexity of encoding and decoding.
    Specifically, for any fixed δ > 0, we exhibit binary linear codes that ensure
    reliable communication at rates within ε > 0 of capacity with block length n =
    O(1/ε 2+δ ), construction complexity Θ(n), and encoding/decoding complexity Θ(n
    log n).

  text: Polar codes represent one of the major recent breakthroughs in coding theory
    and, because of their attractive features, they have been selected for the incoming
    5G standard. As such, a lot of attention has been devoted to the development of
    decoding algorithms with good error performance and efficient hardware implementation.
    One of the leading candidates in this regard is represented by successive-cancellation
    list (SCL) decoding. However, its hardware implementation requires a large amount
    of memory. Recently, a partitioned SCL (PSCL) decoder has been proposed to significantly
    reduce the memory consumption. In this paper, we consider the paradigm of PSCL
    decoding from a practical standpoint, and we provide several improvements. First,
    by changing the target signal-to-noise ratio and consequently modifying the construction
    of the code, we are able to improve the performance at no additional computational,
    latency, or memory cost. Second, we bridge the performance gap between SCL and
    PSCL decoding by introducing a generalized PSCL decoder and a layered PSCL decoder.
    In this way, we obtain almost the same performance of the SCL decoder with a significantly
    lower memory requirement, as testified by hardware implementation results. Third,
    we present an optimal scheme to allocate cyclic redundancy checks. Finally, we
    provide a lower bound on the list size that guarantees optimal maximum a posteriori
    performance for the binary erasure channel.

  text: 'We present a coding paradigm that provides a new achievable rate for the
    primitive relay channel by combining compress-and-forward and decode-and-forward
    with a chaining construction. In the primitive relay channel model, the source
    broadcasts a message to the relay and to the destination; and the relay facilitates
    this communication by sending an additional message to the destination through
    a separate channel. Two well-known coding approaches for this setting are decode-and-forward
    and compress-and-forward: in the former, the relay decodes the message and sends
    some of the information to the destination; in the latter, the relay does not
    attempt to decode, but it sends a compressed description of the received sequence
    to the destination via Wyner-Ziv coding. In our scheme, we transmit over pairs
    of blocks and we use compress-and-forward for the first block and decode-and-forward
    for the second. In particular, in the first block, the relay does not attempt
    to decode and it sends only a part of the compressed description of the received
    sequence; in the second block, the relay decodes the message and sends this information
    plus the remaining part of the compressed sequence relative to the first block.
    As a result, we strictly outperform both compress-and- forward and decode-and-forward.
    Furthermore, this paradigm can be implemented with a low-complexity polar coding
    scheme that has the typical attractive features of polar codes, i.e., quasi-linear
    encoding/decoding complexity and super-polynomial decay of the error probability.
    Throughout the paper we consider as a running example the special case of the
    erasure relay channel and we compare the rates achievable by our proposed scheme
    with the existing upper and lower bounds.'

  text: We survey coding techniques that enable reliable transmission at rates that
    approach the capacity of an arbitrary discrete memoryless channel. In particular,
    we take the point of view of modern coding theory and discuss how recent advances
    in coding for symmetric channels help provide more efficient solutions for the
    asymmetric case. We consider, in more detail, three basic coding paradigms. The
    first one is Gallager's scheme that consists of concatenating a linear code with
    a non-linear mapping so that the input distribution can be appropriately shaped.
    We explicitly show that both polar codes and spatially coupled codes can be employed
    in this scenario. Furthermore, we derive a scaling law between the gap to capacity,
    the cardinality of the input and output alphabets, and the required size of the
    mapper. The second one is an integrated scheme in which the code is used both
    for source coding, in order to create codewords distributed according to the capacity-achieving
    input distribution, and for channel coding, in order to provide error protection.
    Such a technique has been recently introduced by Honda and Yamamoto in the context
    of polar codes, and we show how to apply it also to the design of sparse graph
    codes. The third paradigm is based on an idea of Böcherer and Mathar, and separates
    the two tasks of source coding and channel coding by a chaining construction that
    binds together several codewords. We present conditions for the source code and
    the channel code, and we describe how to combine any source code with any channel
    code that fulfill those conditions, in order to provide capacity-achieving schemes
    for asymmetric channels. In particular, we show that polar codes, spatially coupled
    codes, and homophonic codes are suitable as basic building blocks of the proposed
    coding strategy. Rather than focusing on the exact details of the schemes, the
    purpose of this tutorial is to present different coding techniques that can then
    be implemented with many variants. There is no absolute winner and, in order to
    understand the most suitable technique for a specific application scenario, we
    provide a detailed comparison that takes into account several performance metrics.
