text: Supraglacial debris covers 7% of mountain glacier area globally and generally
reduces glacier surface melt. Enhanced energy absorption at ice cliffs and supraglacial
ponds scattered across the debris surface leads these features to contribute disproportionately
to glacier-wide ablation. However, the degree to which cliffs and ponds actually
increase melt rates remains unclear, as these features have only been studied
in a detailed manner for selected locations, almost exclusively in High Mountain
Asia. In this study we model the surface energy balance for debris-covered ice,
ice cliffs, and supraglacial ponds with a set of automatic weather station records
representing the global prevalence of debris-covered glacier ice. We generate
5000 random sets of values for physical parameters using probability distributions
derived from literature, which we use to investigate relative melt rates and to
isolate the melt responses of debris, cliffs and ponds to the site-specific meteorological
forcing. Modelled sub-debris melt rates are primarily controlled by debris thickness
and thermal conductivity. At a reference thickness of 0.1 m, sub-debris melt rates
vary considerably, differing by up to a factor of four between sites, mainly attributable
to air temperature differences. We find that melt rates for ice cliffs are consistently
2–3× the melt rate for clean glacier ice, but this melt enhancement decays with
increasing clean ice melt rates. Energy absorption at supraglacial ponds is dominated
by latent heat exchange and is therefore highly sensitive to wind speed and relative
humidity, but is generally less than for clean ice. Our results provide reference
melt enhancement factors for melt modelling of debris-covered glacier sites, globally,
while highlighting the need for direct measurement of debris-covered glacier surface
characteristics, physical parameters, and local meteorological conditions at a
variety of sites around the world.

text: 'We present Cross-Client Label Propagation(XCLP), a new method for transductive
federated learning. XCLP estimates a data graph jointly from the data of multiple
clients and computes labels for the unlabeled data by propagating label information
across the graph. To avoid clients having to share their data with anyone, XCLP
employs two cryptographically secure protocols: secure Hamming distance computation
and secure summation. We demonstrate two distinct applications of XCLP within
federated learning. In the first, we use it in a one-shot way to predict labels
for unseen test points. In the second, we use it to repeatedly pseudo-label unlabeled
training data in a federated semi-supervised setting. Experiments on both real
federated and standard benchmark datasets show that in both applications XCLP
achieves higher classification accuracy than alternative approaches.'

text: 'Modern machine learning tasks often require considering not just one but
multiple objectives. For example, besides the prediction quality, this could be
the efficiency, robustness or fairness of the learned models, or any of their
combinations. Multi-objective learning offers a natural framework for handling
such problems without having to commit to early trade-offs. Surprisingly, statistical
learning theory so far offers almost no insight into the generalization properties
of multi-objective learning. In this work, we make first steps to fill this gap:
we establish foundational generalization bounds for the multi-objective setting
as well as generalization and excess bounds for learning with scalarizations.
We also provide the first theoretical analysis of the relation between the Pareto-optimal
sets of the true objectives and the Pareto-optimal sets of their empirical approximations
from training data. In particular, we show a surprising asymmetry: all Pareto-optimal
solutions can be approximated by empirically Pareto-optimal ones, but not vice
versa.'

text: Randomized smoothing is currently considered the state-of-the-art method to
obtain certifiably robust classifiers. Despite its remarkable performance, the
method is associated with various serious problems such as “certified accuracy
waterfalls”, certification vs. accuracy trade-off, or even fairness issues. Input-dependent
smoothing approaches have been proposed with intention of overcoming these flaws.
However, we demonstrate that these methods lack formal guarantees and so the resulting
certificates are not justified. We show that in general, the input-dependent smoothing
suffers from the curse of dimensionality, forcing the variance function to have
low semi-elasticity. On the other hand, we provide a theoretical and practical
framework that enables the usage of input-dependent smoothing even in the presence
of the curse of dimensionality, under strict restrictions. We present one concrete
design of the smoothing variance function and test it on CIFAR10 and MNIST. Our
design mitigates some of the problems of classical smoothing and is formally underlined,
yet further improvement of the design is still necessary.

text: DNA methylation plays essential homeostatic functions in eukaryotic genomes.
In animals, DNA methylation is also developmentally regulated and, in turn, regulates
development. In the past two decades, huge research effort has endorsed the understanding
that DNA methylation plays a similar role in plant development, especially during
sexual reproduction. The power of whole-genome sequencing and cell isolation techniques,
as well as bioinformatics tools, have enabled recent studies to reveal dynamic
changes in DNA methylation during germline development. Furthermore, the combination
of these technological advances with genetics, developmental biology and cell
biology tools has revealed functional methylation reprogramming events that control
gene and transposon activities in flowering plant germlines. In this review, we
discuss the major advances in our knowledge of DNA methylation dynamics during
male and female germline development in flowering plants.

text: Sperm chromatin is typically transformed by protamines into a compact and
transcriptionally inactive state1,2. Sperm cells of flowering plants lack protamines,
yet they have small, transcriptionally active nuclei with chromatin condensed
through an unknown mechanism3,4. Here we show that a histone variant, H2B.8, mediates
sperm chromatin and nuclear condensation in Arabidopsis thaliana. Loss of H2B.8
causes enlarged sperm nuclei with dispersed chromatin, whereas ectopic expression
in somatic cells produces smaller nuclei with aggregated chromatin. This result
demonstrates that H2B.8 is sufficient for chromatin condensation. H2B.8 aggregates
transcriptionally inactive AT-rich chromatin into phase-separated condensates,
which facilitates nuclear compaction without reducing transcription. Reciprocal
crosses show that mutation of h2b.8 reduces male transmission, which suggests
that H2B.8-mediated sperm compaction is important for fertility. Altogether, our
results reveal a new mechanism of nuclear compaction through global aggregation
of unexpressed chromatin. We propose that H2B.8 is an evolutionary innovation
of flowering plants that achieves nuclear condensation compatible with active
transcription.

text: "In modern sample-driven Prophet Inequality, an adversary chooses a sequence
of n items with values v1,v2,…,vn to be presented to a decision maker (DM). The
process follows in two phases. In the first phase (sampling phase), some items,
possibly selected at random, are revealed to the DM, but she can never accept
them. In the second phase, the DM is presented with the other items in a random
order and online fashion. For each item, she must make an irrevocable decision
to either accept the item and stop the process or reject the item forever and
proceed to the next item. The goal of the DM is to maximize the expected value
as compared to a Prophet (or offline algorithm) that has access to all information.
In this setting, the sampling phase has no cost and is not part of the optimization
process. However, in many scenarios, the samples are obtained as part of the decision-making
process.\r\nWe model this aspect as a two-phase Prophet Inequality where an adversary
chooses a sequence of 2n items with values v1,v2,…,v2n and the items are randomly
ordered. Finally, there are two phases of the Prophet Inequality problem with
the first n-items and the rest of the items, respectively. We show that some basic
algorithms achieve a ratio of at most 0.450. We present an algorithm that achieves
a ratio of at least 0.495. Finally, we show that for every algorithm the ratio
it can achieve is at most 0.502. Hence our algorithm is near-optimal."

text: Given a place ω of a global function field K over a finite field, with
associated affine function ring Rω and completion Kω , the aim of this paper
is to give an effective joint equidistribution result for renormalized primitive
lattice points (a,b)∈Rω2 in the plane Kω2 , and for renormalized solutions
to the gcd equation ax+by=1 . The main tools are techniques of Goronik and Nevo
for counting lattice points in well-rounded families of subsets. This gives a
sharper analog in positive characteristic of a result of Nevo and the first author
for the equidistribution of the primitive lattice points in \ZZ2 .
acknowledgement: "The authors warmly thank Amos Nevo for having presented the authors
to each other during\r\na beautiful conference in Goa in February 2016, where the
idea of this paper was born. The\r\nfirst author thanks the IHES for two post-doctoral

text: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
a conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
universality classes of dynamics and invite their further theoretical and experimental
studies.

text: "We consider the problem of approximating the reachability probabilities in
Markov decision processes (MDP) with uncountable (continuous) state and action
spaces. While there are algorithms that, for special classes of such MDP, provide
a sequence of approximations converging to the true value in the limit, our aim
is to obtain an algorithm with guarantees on the precision of the approximation.\r\nAs
this problem is undecidable in general, assumptions on the MDP are necessary.
Our main contribution is to identify sufficient assumptions that are as weak as
possible, thus approaching the \"boundary\" of which systems can be correctly
and reliably analyzed. To this end, we also argue why each of our assumptions
is necessary for algorithms based on processing finitely many observations.\r\nWe
present two solution variants. The first one provides converging lower bounds
under weaker assumptions than typical ones from previous works concerned with
guarantees. The second one then utilizes stronger assumptions to additionally
provide converging upper bounds. Altogether, we obtain an anytime algorithm, i.e.
yielding a sequence of approximants with known and iteratively improving precision,
converging to the true value in the limit. Besides, due to the generality of our
assumptions, our algorithms are very general templates, readily allowing for various
heuristics from literature in contrast to, e.g., a specific discretization algorithm.
Our theoretical contribution thus paves the way for future practical improvements
without sacrificing correctness guarantees."

text: "The ability to scale out training workloads has been one of the key performance
enablers of deep learning. The main scaling approach is data-parallel GPU-based
training, which has been boosted by hardware and software support for highly efficient
point-to-point communication, and in particular via hardware bandwidth over-provisioning.
Overprovisioning comes at a cost: there is an order of magnitude price difference
between \"cloud-grade\" servers with such support, relative to their popular \"consumer-grade\"
counterparts, although single server-grade and consumer-grade GPUs can have similar
computational envelopes.\r\n\r\nIn this paper, we show that the costly hardware
overprovisioning approach can be supplanted via algorithmic and system design,
and propose a framework called CGX, which provides efficient software support
for compressed communication in ML applications, for both multi-GPU single-node
training, as well as larger-scale multi-node training. CGX is based on two technical
advances: At the system level, it relies on a re-developed communication stack
for ML frameworks, which provides flexible, highly-efficient support for compressed
communication. At the application level, it provides seamless, parameter-free
integration with popular frameworks, so that end-users do not have to modify training
recipes, nor significant training code. This is complemented by a layer-wise adaptive
compression technique which dynamically balances compression gains with accuracy
preservation. CGX integrates with popular ML frameworks, providing up to 3X speedups
for multi-GPU nodes based on commodity hardware, and order-of-magnitude improvements
in the multi-node setting, with negligible impact on accuracy."

text: 'Memorization of the relation between entities in a dataset can lead to privacy
issues when using a trained model for question answering. We introduce Relational
Memorization (RM) to understand, quantify and control this phenomenon. While bounding
general memorization can have detrimental effects on the performance of a trained
model, bounding RM does not prevent effective learning. The difference is most
pronounced when the data distribution is long-tailed, with many queries having
only few training examples: Impeding general memorization prevents effective learning,
while impeding only relational memorization still allows learning general properties
of the underlying concepts. We formalize the notion of Relational Privacy (RP)
and, inspired by Differential Privacy (DP), we provide a possible definition of
Differential Relational Privacy (DrP). These notions can be used to describe and
compute bounds on the amount of RM in a trained model. We illustrate Relational
Privacy concepts in experiments with large-scale models for Question Answering.'

text: Photoredox-mediated Ni-catalyzed cross-couplings are powerful transformations
to form carbon–heteroatom bonds and are generally photocatalyzed by noble metal
complexes. Low-cost and easy-to-prepare carbon dots (CDs) are attractive quasi-homogeneous
photocatalyst alternatives, but their applicability is limited by their short
photoluminescence (PL) lifetimes. By tuning the surface and PL properties of CDs,
we designed colloidal CD nano-photocatalysts for a broad range of Ni-mediated
cross-couplings between aryl halides and nucleophiles. In particular, a CD decorated
with amino groups permitted coupling to a wide range of aryl halides and thiols
under mild, base-free conditions. Mechanistic studies suggested dynamic quenching
of the CD excited state by the Ni co-catalyst and identified that pyridinium iodide
(pyHI), a previously used additive in metallaphotocatalyzed cross-couplings, can
also act as a photocatalyst in such transformations.

text: We demonstrate that several visible-light-mediated carbon−heteroatom cross-coupling
reactions can be carried out using a photoactive NiII precatalyst that forms in
situ from a nickel salt and a bipyridine ligand decorated with two carbazole groups
(Ni(Czbpy)Cl2). The activation of this precatalyst towards cross-coupling reactions
follows a hitherto undisclosed mechanism that is different from previously reported
light-responsive nickel complexes that undergo metal-to-ligand charge transfer.
Theoretical and spectroscopic investigations revealed that irradiation of Ni(Czbpy)Cl2
with visible light causes an initial intraligand charge transfer event that triggers
productive catalysis. Ligand polymerization affords a porous, recyclable organic
polymer for heterogeneous nickel catalysis of cross-coupling reactions. The heterogeneous
catalyst shows stable performance in a packed-bed flow reactor during a week of
continuous operation.

text: In this work, a feed-forward artificial neural network (FF-ANN) design capable
of locating eigensolutions to Schrödinger's equation via self-supervised learning
is outlined. Based on the input potential determining the nature of the quantum
problem, the presented FF-ANN strategy identifies valid solutions solely by minimizing
Schrödinger's equation encoded in a suitably designed global loss function. In
addition to benchmark calculations of prototype systems with known analytical
solutions, the outlined methodology was also applied to experimentally accessible
quantum systems, such as the vibrational states of molecular hydrogen H2 and its
isotopologues HD and D2 as well as the torsional tunnel splitting in the phenol
molecule. It is shown that in conjunction with the use of SIREN activation functions
a high accuracy in the energy eigenvalues and wavefunctions is achieved without
the requirement to adjust the implementation to the vastly different range of
input potentials, thereby even considering problems under periodic boundary conditions.

text: 'Lymph nodes (LNs) comprise two main structural elements: fibroblastic reticular
cells that form dedicated niches for immune cell interaction and capsular fibroblasts
that build a shell around the organ. Immunological challenge causes LNs to increase
more than tenfold in size within a few days. Here, we characterized the biomechanics
of LN swelling on the cellular and organ scale. We identified lymphocyte trapping
by influx and proliferation as drivers of an outward pressure force, causing fibroblastic
reticular cells of the T-zone (TRCs) and their associated conduits to stretch.
After an initial phase of relaxation, TRCs sensed the resulting strain through
cell matrix adhesions, which coordinated local growth and remodeling of the stromal
network. While the expanded TRC network readopted its typical configuration, a
massive fibrotic reaction of the organ capsule set in and countered further organ
expansion. Thus, different fibroblast populations mechanically control LN swelling
in a multitier fashion.'

text: Neurons can change their classical neurotransmitters during ontogeny, sometimes
going through stages of dual release. Here, we explored the development of the
neurotransmitter identity of neurons of the avian nucleus isthmi parvocellularis
(Ipc), whose axon terminals are retinotopically arranged in the optic tectum (TeO)
and exert a focal gating effect upon the ascending transmission of retinal inputs.
Although cholinergic and glutamatergic markers are both found in Ipc neurons and
terminals of adult pigeons and chicks, the mRNA expression of the vesicular acetylcholine
transporter, VAChT, is weak or absent. To explore how the Ipc neurotransmitter
identity is established during ontogeny, we analyzed the expression of mRNAs coding
for cholinergic (ChAT, VAChT, and CHT) and glutamatergic (VGluT2 and VGluT3) markers
in chick embryos at different developmental stages. We found that between E12
and E18, Ipc neurons expressed all cholinergic mRNAs and also VGluT2 mRNA; however,
from E16 through posthatch stages, VAChT mRNA expression was specifically diminished.
Our ex vivo deposits of tracer crystals and intracellular filling experiments
revealed that Ipc axons exhibit a mature paintbrush morphology late in development,
experiencing marked morphological transformations during the period of presumptive
dual vesicular transmitter release. Additionally, although ChAT protein immunoassays
increasingly label the growing Ipc axon, this labeling was consistently restricted
to sparse portions of the terminal branches. Combined, these results suggest that
the synthesis of glutamate and acetylcholine, and their vesicular release, is
complexly linked to the developmental processes of branching, growing and remodeling
of these unique axons.
