  text: Bundling crossings is a strategy which can enhance the readability of graph
    drawings. In this paper we consider bundlings for families of pseudosegments,
    i.e., simple curves such that any two have share at most one point at which they
    cross. Our main result is that there is a polynomial-time algorithm to compute
    an 8-approximation of the bundled crossing number of such instances (up to adding
    a term depending on the facial structure). This 8-approximation also holds for
    bundlings of good drawings of graphs. In the special case of circular drawings
    the approximation factor is 8 (no extra term), this improves upon the 10-approximation
    of Fink et al. [6]. We also show how to compute a 92-approximation when the intersection
    graph of the pseudosegments is bipartite.

  text: The interaction between a cell and its environment shapes fundamental intracellular
    processes such as cellular metabolism. In most cases growth rate is treated as
    a proximal metric for understanding the cellular metabolic status. However, changes
    in growth rate might not reflect metabolic variations in individuals responding
    to environmental fluctuations. Here we use single-cell microfluidics-microscopy
    combined with transcriptomics, proteomics and mathematical modelling to quantify
    the accumulation of glucose within Escherichia coli cells. In contrast to the
    current consensus, we reveal that environmental conditions which are comparatively
    unfavourable for growth, where both nutrients and salinity are depleted, increase
    glucose accumulation rates in individual bacteria and population subsets. We find
    that these changes in metabolic function are underpinned by variations at the
    translational and posttranslational level but not at the transcriptional level
    and are not dictated by changes in cell size. The metabolic response-characteristics
    identified greatly advance our fundamental understanding of the interactions between
    bacteria and their environment and have important ramifications when investigating
    cellular processes where salinity plays an important role.

  text: CRISPR (Clustered regularly interspaced short palindromic repeats)-Cas (CRISPR-associated)
    systems are a type of adaptive immune response in bacteria and archaea that utilize
    crRNA (CRISPR RNA)-guided effector complexes to target complementary RNA or DNA
    for destruction. The prototypical type III-A and III-B CRISPR-Cas systems utilize
    multi-subunit effector complexes composed of individual proteins to cleave ssRNA
    targets at 6-nt intervals, as well as non-specifically degrading ssDNA and activating
    cyclic oligoadenylate (cOA) synthesis. Recent studies have shown that type III
    systems can contain subunit fusions yet maintain canonical type III RNA-targeting
    capabilities. To understand how a multi-subunit fusion effector functions, we
    determine structures of a variant type III-D effector and biochemically characterize
    how it cleaves RNA targets. These findings provide insights into how multi-subunit
    fusion proteins are tethered together and assemble into an active and programmable
    RNA endonuclease, how the effector utilizes a novel mechanism for target RNA seeding,
    and the structural basis for the evolution of type III effector complexes. Furthermore,
    our results provide a blueprint for fusing subunits in class 1 effectors for design
    of user-defined effector complexes with disparate activities.</jats:p><jats:sec><jats:title>Important
    note</jats:title><jats:p>While this manuscript was in preparation, a manuscript
    describing the structure of the type III-E effector was published<jats:sup>1</jats:sup>.
    We reference these important findings; however, a careful comparison of the structures
    will follow once the coordinates have been released by the PDB.

  text: Observations of the most luminous quasars at high redshifts (z>6) have revealed
    that the largest supermassive black holes (SMBHs) at those epochs tend to be substantially
    overmassive relative to their host galaxies compared to the local relations, suggesting
    they experienced rapid early growth phases. We propose an assembly model for the
    SMBHs that end up in rare massive ∼1012 M⊙ host halos at z∼6−7, applying a kinetic
    feedback prescription for BHs accreting above the Eddington rate, provided by
    radiation hydrodynamic simulations for the long-term evolution of the accretion-flow
    structure. The large inflow rates into these halos during their assembly enable
    the formation of >109 M⊙ SMBHs by z∼6, even starting from stellar-mass seeds at
    z∼30, and even in the presence of outflows that reduce the BH feeding rate, especially
    at early times. This mechanism also naturally yields a high BH-to-galaxy mass
    ratio of >0.01 before the SMBH mass reaches MBH>109 M⊙ by z∼6. These fast-growing
    SMBH progenitors are bright enough to be detected by upcoming observations with
    the James Webb Space Telescope over a wide range of redshift (7<z<15), regardless
    of how they were seeded.

  text: Imbalanced mitochondrial dNTP pools are known players in the pathogenesis
    of multiple human diseases. Here we show that, even under physiological conditions,
    dGTP is largely overrepresented among other dNTPs in mitochondria of mouse tissues
    and human cultured cells. In addition, a vast majority of mitochondrial dGTP is
    tightly bound to NDUFA10, an accessory subunit of complex I of the mitochondrial
    respiratory chain. NDUFA10 shares a deoxyribonucleoside kinase (dNK) domain with
    deoxyribonucleoside kinases in the nucleotide salvage pathway, though no specific
    function beyond stabilizing the complex I holoenzyme has been described for this
    subunit. We mutated the dNK domain of NDUFA10 in human HEK-293T cells while preserving
    complex I assembly and activity. The NDUFA10E160A/R161A shows reduced dGTP binding
    capacity in vitro and leads to a 50% reduction in mitochondrial dGTP content,
    proving that most dGTP is directly bound to the dNK domain of NDUFA10. This interaction
    may represent a hitherto unknown mechanism regulating mitochondrial dNTP availability
    and linking oxidative metabolism to DNA maintenance.

  text: Given a non-singular diagonal cubic hypersurface X⊂Pn−1 over Fq(t) with char(Fq)≠3,
    we show that the number of rational points of height at most |P| is O(|P|3+ε)
    for n=6 and O(|P|2+ε) for n=4. In fact, if n=4 and char(Fq)>3 we prove that the
    number of rational points away from any rational line contained in X is bounded
    by O(|P|3/2+ε). From the result in 6 variables we deduce weak approximation for
    diagonal cubic hypersurfaces for n≥7 over Fq(t) when char(Fq)>3 and handle Waring's
    problem for cubes in 7 variables over Fq(t) when char(Fq)≠3. Our results answer
    a question of Davenport regarding the number of solutions of bounded height to
    x31+x32+x33=x34+x35+x36 with xi∈Fq[t].

  text: "Deep learning has enabled breakthroughs in challenging computing problems
    and has emerged as the standard problem-solving tool for computer vision and natural
    language processing tasks.\r\nOne exception to this trend is safety-critical tasks
    where robustness and resilience requirements contradict the black-box nature of
    neural networks. \r\nTo deploy deep learning methods for these tasks, it is vital
    to provide guarantees on neural network agents' safety and robustness criteria.
    \r\nThis can be achieved by developing formal verification methods to verify the
    safety and robustness properties of neural networks.\r\n\r\nOur goal is to design,
    develop and assess safety verification methods for neural networks to improve
    their reliability and trustworthiness in real-world applications.\r\nThis thesis
    establishes techniques for the verification of compressed and adversarially trained
    models as well as the design of novel neural networks for verifiably safe decision-making.\r\n\r\nFirst,
    we establish the problem of verifying quantized neural networks. Quantization
    is a technique that trades numerical precision for the computational efficiency
    of running a neural network and is widely adopted in industry.\r\nWe show that
    neglecting the reduced precision when verifying a neural network can lead to wrong
    conclusions about the robustness and safety of the network, highlighting that
    novel techniques for quantized network verification are necessary. We introduce
    several bit-exact verification methods explicitly designed for quantized neural
    networks and experimentally confirm on realistic networks that the network's robustness
    and other formal properties are affected by the quantization.\r\n\r\nFurthermore,
    we perform a case study providing evidence that adversarial training, a standard
    technique for making neural networks more robust, has detrimental effects on the
    network's performance. This robustness-accuracy tradeoff has been studied before
    regarding the accuracy obtained on classification datasets where each data point
    is independent of all other data points. On the other hand, we investigate the
    tradeoff empirically in robot learning settings where a both, a high accuracy
    and a high robustness, are desirable.\r\nOur results suggest that the negative
    side-effects of adversarial training outweigh its robustness benefits in practice.\r\n\r\nFinally,
    we consider the problem of verifying safety when running a Bayesian neural network
    policy in a feedback loop with systems over the infinite time horizon. Bayesian
    neural networks are probabilistic models for learning uncertainties in the data
    and are therefore often used on robotic and healthcare applications where data
    is inherently stochastic.\r\nWe introduce a method for recalibrating Bayesian
    neural networks so that they yield probability distributions over safe decisions
    only.\r\nOur method learns a safety certificate that guarantees safety over the
    infinite time horizon to determine which decisions are safe in every possible
    state of the system.\r\nWe demonstrate the effectiveness of our approach on a
    series of reinforcement learning benchmarks."

  text: "Vacuolar-type H+-ATPase (V-ATPase) is a multimeric complex present in a variety
    of cellular membranes that acts as an ATP-dependent proton pump and plays a key
    role in pH homeostasis and intracellular signalling pathways. In humans, 22 autosomal
    genes encode for a redundant set of subunits allowing the composition of diverse
    V-ATPase complexes with specific properties and expression. Sixteen subunits have
    been linked to human disease.\r\nHere we describe 26 patients harbouring 20 distinct
    pathogenic de novo missense ATP6V1A variants, mainly clustering within the ATP
    synthase α/β family-nucleotide-binding domain. At a mean age of 7 years (extremes:
    6 weeks, youngest deceased patient to 22 years, oldest patient) clinical pictures
    included early lethal encephalopathies with rapidly progressive massive brain
    atrophy, severe developmental epileptic encephalopathies and static intellectual
    disability with epilepsy. The first clinical manifestation was early hypotonia,
    in 70%; 81% developed epilepsy, manifested as developmental epileptic encephalopathies
    in 58% of the cohort and with infantile spasms in 62%; 63% of developmental epileptic
    encephalopathies failed to achieve any developmental, communicative or motor skills.
    Less severe outcomes were observed in 23% of patients who, at a mean age of 10
    years and 6 months, exhibited moderate intellectual disability, with independent
    walking and variable epilepsy. None of the patients developed communicative language.
    Microcephaly (38%) and amelogenesis imperfecta/enamel dysplasia (42%) were additional
    clinical features. Brain MRI demonstrated hypomyelination and generalized atrophy
    in 68%. Atrophy was progressive in all eight individuals undergoing repeated MRIs.</jats:p>\r\n
    \              <jats:p>Fibroblasts of two patients with developmental epileptic
    encephalopathies showed decreased LAMP1 expression, Lysotracker staining and increased
    organelle pH, consistent with lysosomal impairment and loss of V-ATPase function.
    Fibroblasts of two patients with milder disease, exhibited a different phenotype
    with increased Lysotracker staining, decreased organelle pH and no significant
    modification in LAMP1 expression. Quantification of substrates for lysosomal enzymes
    in cellular extracts from four patients revealed discrete accumulation. Transmission
    electron microscopy of fibroblasts of four patients with variable severity and
    of induced pluripotent stem cell-derived neurons from two patients with developmental
    epileptic encephalopathies showed electron-dense inclusions, lipid droplets, osmiophilic
    material and lamellated membrane structures resembling phospholipids. Quantitative
    assessment in induced pluripotent stem cell-derived neurons identified significantly
    smaller lysosomes.\r\nATP6V1A-related encephalopathy represents a new paradigm
    among lysosomal disorders. It results from a dysfunctional endo-lysosomal membrane
    protein causing altered pH homeostasis. Its pathophysiology implies intracellular
    accumulation of substrates whose composition remains unclear, and a combination
    of developmental brain abnormalities and neurodegenerative changes established
    during prenatal and early postanal development, whose severity is variably determined
    by specific pathogenic variants."

  text: "The complex yarn structure of knitted and woven fabrics gives rise to both
    a mechanical and\r\nvisual complexity. The small-scale interactions of yarns colliding
    with and pulling on each\r\nother result in drastically different large-scale
    stretching and bending behavior, introducing\r\nanisotropy, curling, and more.
    While simulating cloth as individual yarns can reproduce this\r\ncomplexity and
    match the quality of real fabric, it may be too computationally expensive for\r\nlarge
    fabrics. On the other hand, continuum-based approaches do not need to discretize
    the\r\ncloth at a stitch-level, but it is non-trivial to find a material model
    that would replicate the\r\nlarge-scale behavior of yarn fabrics, and they discard
    the intricate visual detail. In this thesis,\r\nwe discuss three methods to try
    and bridge the gap between small-scale and large-scale yarn\r\nmechanics using
    numerical homogenization: fitting a continuum model to periodic yarn simulations,
    adding mechanics-aware yarn detail onto thin-shell simulations, and quantitatively\r\nfitting
    yarn parameters to physical measurements of real fabric.\r\nTo start, we present
    a method for animating yarn-level cloth effects using a thin-shell solver.\r\nWe
    first use a large number of periodic yarn-level simulations to build a model of
    the potential\r\nenergy density of the cloth, and then use it to compute forces
    in a thin-shell simulator. The\r\nresulting simulations faithfully reproduce expected
    effects like the stiffening of woven fabrics\r\nand the highly deformable nature
    and anisotropy of knitted fabrics at a fraction of the cost of\r\nfull yarn-level
    simulation.\r\nWhile our thin-shell simulations are able to capture large-scale
    yarn mechanics, they lack\r\nthe rich visual detail of yarn-level simulations.
    Therefore, we propose a method to animate\r\nyarn-level cloth geometry on top
    of an underlying deforming mesh in a mechanics-aware\r\nfashion in real time.
    Using triangle strains to interpolate precomputed yarn geometry, we are\r\nable
    to reproduce effects such as knit loops tightening under stretching at negligible
    cost.\r\nFinally, we introduce a methodology for inverse-modeling of yarn-level
    mechanics of cloth,\r\nbased on the mechanical response of fabrics in the real
    world. We compile a database from\r\nphysical tests of several knitted fabrics
    used in the textile industry spanning diverse physical\r\nproperties like stiffness,
    nonlinearity, and anisotropy. We then develop a system for approximating these
    mechanical responses with yarn-level cloth simulation, using homogenized\r\nshell
    models to speed up computation and adding some small-but-necessary extensions
    to\r\nyarn-level models used in computer graphics.\r\n"

  text: Complex wiring between neurons underlies the information-processing network
    enabling all brain functions, including cognition and memory. For understanding
    how the network is structured, processes information, and changes over time, comprehensive
    visualization of the architecture of living brain tissue with its cellular and
    molecular components would open up major opportunities. However, electron microscopy
    (EM) provides nanometre-scale resolution required for full <jats:italic>in-silico</jats:italic>
    reconstruction<jats:sup>1–5</jats:sup>, yet is limited to fixed specimens and
    static representations. Light microscopy allows live observation, with super-resolution
    approaches<jats:sup>6–12</jats:sup> facilitating nanoscale visualization, but
    comprehensive 3D-reconstruction of living brain tissue has been hindered by tissue
    photo-burden, photobleaching, insufficient 3D-resolution, and inadequate signal-to-noise
    ratio (SNR). Here we demonstrate saturated reconstruction of living brain tissue.
    We developed an integrated imaging and analysis technology, adapting stimulated
    emission depletion (STED) microscopy<jats:sup>6,13</jats:sup> in extracellularly
    labelled tissue<jats:sup>14</jats:sup> for high SNR and near-isotropic resolution.
    Centrally, a two-stage deep-learning approach leveraged previously obtained information
    on sample structure to drastically reduce photo-burden and enable automated volumetric
    reconstruction down to single synapse level. Live reconstruction provides unbiased
    analysis of tissue architecture across time in relation to functional activity
    and targeted activation, and contextual understanding of molecular labelling.
    This adoptable technology will facilitate novel insights into the dynamic functional
    architecture of living brain tissue.

  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: "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: Rest-frame ultraviolet (UV) emission lines probe electron densities, gas-phase
    abundances, metallicities, and ionization parameters of the emitting star-forming
    galaxies and their environments. The strongest main UV emission line, Lyα, has
    been instrumental in advancing the general knowledge of galaxy formation in the
    early universe. However, observing Lyα emission becomes increasingly challenging
    at z ≳ 6 when the neutral hydrogen fraction of the circumgalactic and intergalactic
    media increases. Secondary weaker UV emission lines provide important alternative
    methods for studying galaxy properties at high redshift. We present a large sample
    of rest-frame UV emission line sources at intermediate redshift for calibrating
    and exploring the connection between secondary UV lines and the emitting galaxies’
    physical properties and their Lyα emission. The sample of 2052 emission line sources
    with 1.5 < z < 6.4 was collected from integral field data from the MUSE-Wide and
    MUSE-Deep surveys taken as part of Guaranteed Time Observations. The objects were
    selected through untargeted source detection (i.e., no preselection of sources
    as in dedicated spectroscopic campaigns) in the three-dimensional MUSE data cubes.
    We searched optimally extracted one-dimensional spectra of the full sample for
    UV emission features via emission line template matching, resulting in a sample
    of more than 100 rest-frame UV emission line detections. We show that the detection
    efficiency of (non-Lyα) UV emission lines increases with survey depth, and that
    the emission line strength of He IIλ1640 Å, [O III] λ1661 + O III] λ1666, and
    [Si III] λ1883 + Si III] λ1892 correlate with the strength of [C III] λ1907 +
    C III] λ1909. The rest-frame equivalent width (EW0) of [C III] λ1907 + C III]
    λ1909 is found to be roughly 0.22 ± 0.18 of EW0(Lyα). We measured the velocity
    offsets of resonant emission lines with respect to systemic tracers. For C IVλ1548
    + C IVλ1551 we find that ΔvC IV ≲ 250 km s−1, whereas ΔvLyα falls in the range
    of 250−500 km s−1 which is in agreement with previous results from the literature.
    The electron density ne measured from [Si III] λ1883 + Si III] λ1892 and [C III]
    λ1907 + C III] λ1909 line flux ratios is generally < 105 cm−3 and the gas-phase
    abundance is below solar at 12 + log10(O/H)≈8. Lastly, we used “PhotoIonization
    Model Probability Density Functions” to infer physical parameters of the full
    sample and individual systems based on photoionization model parameter grids and
    observational constraints from our UV emission line searches. This reveals that
    the UV line emitters generally have ionization parameter log10(U) ≈ −2.5 and metal
    mass fractions that scatter around Z ≈ 10−2, that is Z ≈ 0.66 Z⊙. Value-added
    catalogs of the full sample of MUSE objects studied in this work and a collection
    of UV line emitters from the literature are provided with this paper.

  text: We report the discovery of diffuse extended Lyα emission from redshift 3.1
    to 4.5, tracing cosmic web filaments on scales of 2.5−4 cMpc. These structures
    have been observed in overdensities of Lyα emitters in the MUSE Extremely Deep
    Field, a 140 h deep MUSE observation located in the Hubble Ultra-Deep Field. Among
    the 22 overdense regions identified, five are likely to harbor very extended Lyα
    emission at high significance with an average surface brightness of 5 × 10−20
    erg s−1 cm−2 arcsec−2. Remarkably, 70% of the total Lyα luminosity from these
    filaments comes from beyond the circumgalactic medium of any identified Lyα emitter.
    Fluorescent Lyα emission powered by the cosmic UV background can only account
    for less than 34% of this emission at z ≈ 3 and for not more than 10% at higher
    redshift. We find that the bulk of this diffuse emission can be reproduced by
    the unresolved Lyα emission of a large population of ultra low-luminosity Lyα
    emitters (< 1040 erg s−1), provided that the faint end of the Lyα luminosity function
    is steep (α ⪅ −1.8), it extends down to luminosities lower than 1038 − 1037 erg
    s−1, and the clustering of these Lyα emitters is significant (filling factor <
    1/6). If these Lyα emitters are powered by star formation, then this implies their
    luminosity function needs to extend down to star formation rates < 10−4 M⊙ yr−1.
    These observations provide the first detection of the cosmic web in Lyα emission
    in typical filamentary environments and the first observational clue indicating
    the existence of a large population of ultra low-luminosity Lyα emitters at high
    redshift.

  text: The decline in abundance of Lyman-α (Lyα) emitting galaxies at z ≳ 6 is a
    powerful and commonly used probe to constrain the progress of cosmic reionization.
    We use the CODAII simulation, which is a radiation hydrodynamic simulation featuring
    a box of ∼94 comoving Mpc side length, to compute the Lyα transmission properties
    of the intergalactic medium (IGM) at z ∼ 5.8 to 7. Our results mainly confirm
    previous studies, i.e. we find a declining Lyα transmission with redshift and
    a large sightline-to-sightline variation. However, motivated by the recent discovery
    of blue Lyα peaks at high redshift, we also analyse the IGM transmission on the
    blue side, which shows a rapid decline at z ≳ 6 of the blue transmission. This
    low transmission can be attributed not only to the presence of neutral regions
    but also to the residual neutral hydrogen within ionized regions, for which a
    density even as low as nHI∼10−9cm−3 (sometimes combined with kinematic effects)
    leads to a significantly reduced visibility. Still, we find that ∼1 per cent of
    sightlines towards M1600AB ∼ −21 galaxies at z ∼ 7 are transparent enough to allow
    a transmission of a blue Lyα peak. We discuss our results in the context of the
    interpretation of observations.

  text: We measure the evolution of the rest-frame UV luminosity function (LF) and
    the stellar mass function (SMF) of Lyman-α (Ly α) emitters (LAEs) from z ∼ 2 to
    z ∼ 6 by exploring ∼4000 LAEs from the SC4K sample. We find a correlation between
    Ly α luminosity (LLy α) and rest-frame UV (MUV), with best fit MUV=−1.6+0.2−0.3log10(LLyα/ergs−1)+47+12−11
    and a shallower relation between LLy α and stellar mass (M⋆), with best fit log10(M⋆/M⊙)=0.9+0.1−0.1log10(LLyα/ergs−1)−28+4.0−3.8⁠.
    An increasing LLy α cut predominantly lowers the number density of faint MUV and
    low M⋆ LAEs. We estimate a proxy for the full UV LFs and SMFs of LAEs with simple
    assumptions of the faint end slope. For the UV LF, we find a brightening of the
    characteristic UV luminosity (M∗UV⁠) with increasing redshift and a decrease of
    the characteristic number density (Φ*). For the SMF, we measure a characteristic
    stellar mass (⁠M∗⋆/M⊙⁠) increase with increasing redshift, and a Φ* decline. However,
    if we apply a uniform luminosity cut of log10(LLyα/ergs−1)≥43.0⁠, we find much
    milder to no evolution in the UV and SMF of LAEs. The UV luminosity density (ρUV)
    of the full sample of LAEs shows moderate evolution and the stellar mass density
    (ρM) decreases, with both being always lower than the total ρUV and ρM of more
    typical galaxies but slowly approaching them with increasing redshift. Overall,
    our results indicate that both ρUV and ρM of LAEs slowly approach the measurements
    of continuum-selected galaxies at z > 6, which suggests a key role of LAEs in
    the epoch of reionization.

  text: We give two fully dynamic algorithms that maintain a (1 + ε)-approximation
    of the weight M of a minimum spanning forest (MSF) of an n-node graph G with edges
    weights in [1, W ], for any ε > 0. (1) Our deterministic algorithm takes O (W
    2 log W /ε3) worst-case update time, which is O (1) if both W and ε are constants.
    (2) Our randomized (Monte-Carlo style) algorithm works with high probability and
    runs in worst-case O (log W /ε4) update time if W = O ((m∗)1/6/log2/3 n), where
    m∗ is the minimum number of edges in the graph throughout all the updates. It
    works even against an adaptive adversary. We complement our algorithmic results
    with two cell-probe lower bounds for dynamically maintaining an approximation
    of the weight of an MSF of a graph.

  text: "We present a deterministic (1+\U0001D45C(1))-approximation (\U0001D45B1/2+\U0001D45C(1)+\U0001D4371+\U0001D45C(1))-time
    algorithm for solving the single-source shortest paths problem on distributed
    weighted networks (the \\sf CONGEST model); here \U0001D45B is the number of nodes
    in the network, \U0001D437 is its (hop) diameter, and edge weights are positive
    integers from 1 to poly(\U0001D45B). This is the first nontrivial deterministic
    algorithm for this problem. It also improves (i) the running time of the randomized
    (1+\U0001D45C(1))-approximation \U0001D442̃ (\U0001D45B√\U0001D4371/4+\U0001D437)-time
    algorithm of Nanongkai [in Proceedings of STOC, 2014, pp. 565--573] by a factor
    of as large as \U0001D45B1/8, and (ii) the \U0001D442(\U0001D716−1log\U0001D716−1)-approximation
    factor of Lenzen and Patt-Shamir's \U0001D442̃ (\U0001D45B1/2+\U0001D716+\U0001D437)-time
    algorithm [in Proceedings of STOC, 2013, pp. 381--390] within the same running
    time. (Throughout, we use \U0001D442̃ (⋅) to hide polylogarithmic factors in \U0001D45B.)
    Our running time matches the known time lower bound of Ω(\U0001D45B/log\U0001D45B‾‾‾‾‾‾‾√+\U0001D437)
    [M. Elkin, SIAM J. Comput., 36 (2006), pp. 433--456], thus essentially settling
    the status of this problem which was raised at least a decade ago [M. Elkin, SIGACT
    News, 35 (2004), pp. 40--57]. It also implies a (2+\U0001D45C(1))-approximation
    (\U0001D45B1/2+\U0001D45C(1)+\U0001D4371+\U0001D45C(1))-time algorithm for approximating
    a network's weighted diameter which almost matches the lower bound by Holzer and
    Pinsker [in Proceedings of OPODIS, 2015, Schloss Dagstuhl. Leibniz-Zent. Inform.,
    Wadern, Germany, 2016, 6]. In achieving this result, we develop two techniques
    which might be of independent interest and useful in other settings: (i) a deterministic
    process that replaces the “hitting set argument” commonly used for shortest paths
    computation in various settings, and (ii) a simple, deterministic construction
    of an (\U0001D45B\U0001D45C(1),\U0001D45C(1))-hop set of size \U0001D45B1+\U0001D45C(1).
    We combine these techniques with many distributed algorithmic techniques, some
    of which are from problems that are not directly related to shortest paths, e.g.,
    ruling sets [A. V. Goldberg, S. A. Plotkin, and G. E. Shannon, SIAM J. Discrete
    Math., 1 (1988), pp. 434--446], source detection [C. Lenzen and D. Peleg, in Proceedings
    of PODC, 2013, pp. 375--382], and partial distance estimation [C. Lenzen and B.
    Patt-Shamir, in Proceedings of PODC, 2015, pp. 153--162]. Our hop set construction
    also leads to single-source shortest paths algorithms in two other settings: (i)
    a (1+\U0001D45C(1))-approximation \U0001D45B\U0001D45C(1)-time algorithm on congested
    cliques, and (ii) a (1+\U0001D45C(1))-approximation \U0001D45B\U0001D45C(1)-pass
    \U0001D45B1+\U0001D45C(1)-space streaming algorithm. The first result answers
    an open problem in [D. Nanongkai, in Proceedings of STOC, 2014, pp. 565--573].
    The second result partially answers an open problem raised by McGregor in 2006
    [List of Open Problems in Sublinear Algorithms: Problem 14]."

  text: To rival the performance of modern integrated circuits, single-molecule devices
    must be designed to exhibit extremely nonlinear current–voltage (I–V) characteristics1,2,3,4.
    A common approach is to design molecular backbones where destructive quantum interference
    (QI) between the highest occupied molecular orbital (HOMO) and the lowest unoccupied
    molecular orbital (LUMO) produces a nonlinear energy-dependent tunnelling probability
    near the electrode Fermi energy (EF)5,6,7,8. However, tuning such systems is not
    straightforward, as aligning the frontier orbitals to EF is hard to control9.
    Here, we instead create a molecular system where constructive QI between the HOMO
    and LUMO is suppressed and destructive QI between the HOMO and strongly coupled
    occupied orbitals of opposite phase is enhanced. We use a series of fluorene oligomers
    containing a central benzothiadiazole10 unit to demonstrate that this strategy
    can be used to create highly nonlinear single-molecule circuits. Notably, we are
    able to reproducibly modulate the conductance of a 6-nm molecule by a factor of
    more than 10^4.
