text: "We propose a novel Stochastic Frank-Wolfe (a.k.a. conditional gradient)\r\nalgorithm
for constrained smooth finite-sum minimization with a generalized\r\nlinear prediction/structure.
This class of problems includes empirical risk\r\nminimization with sparse, low-rank,
or other structured constraints. The\r\nproposed method is simple to implement,
does not require step-size tuning, and\r\nhas a constant per-iteration cost that
is independent of the dataset size.\r\nFurthermore, as a byproduct of the method
we obtain a stochastic estimator of\r\nthe Frank-Wolfe gap that can be used as
a stopping criterion. Depending on the\r\nsetting, the proposed method matches
or improves on the best computational\r\nguarantees for Stochastic Frank-Wolfe
algorithms. Benchmarks on several\r\ndatasets highlight different regimes in which
the proposed method exhibits a\r\nfaster empirical convergence than related methods.
Finally, we provide an\r\nimplementation of all considered methods in an open-source
package."

text: "Intelligent agents should be able to learn useful representations by\r\nobserving
changes in their environment. We model such observations as pairs of\r\nnon-i.i.d.
images sharing at least one of the underlying factors of variation.\r\nFirst,
we theoretically show that only knowing how many factors have changed,\r\nbut
not which ones, is sufficient to learn disentangled representations.\r\nSecond,
we provide practical algorithms that learn disentangled representations\r\nfrom
pairs of images without requiring annotation of groups, individual\r\nfactors,
or the number of factors that have changed. Third, we perform a\r\nlarge-scale
empirical study and show that such pairs of observations are\r\nsufficient to
reliably learn disentangled representations on several benchmark\r\ndata sets.
Finally, we evaluate our learned representations and find that they\r\nare simultaneously
useful on a diverse suite of tasks, including generalization\r\nunder covariate
shifts, fairness, and abstract reasoning. Overall, our results\r\ndemonstrate
that weak supervision enables learning of useful disentangled\r\nrepresentations
in realistic scenarios."

text: "The idea behind the unsupervised learning of disentangled representations
is that real-world data is generated by a few explanatory factors of variation
which can be recovered by unsupervised learning algorithms. In this paper, we
provide a sober look at recent progress in the field and challenge some common
assumptions. We first theoretically show that the unsupervised learning of disentangled
representations is fundamentally impossible without inductive biases on both the
models and the data. Then, we train over 14000\r\n models covering most prominent
methods and evaluation metrics in a reproducible large-scale experimental study
on eight data sets. We observe that while the different methods successfully enforce
properties “encouraged” by the corresponding losses, well-disentangled models
seemingly cannot be identified without supervision. Furthermore, different evaluation
metrics do not always agree on what should be considered “disentangled” and exhibit
systematic differences in the estimation. Finally, increased disentanglement does
not seem to necessarily lead to a decreased sample complexity of learning for
downstream tasks. Our results suggest that future work on disentanglement learning
should be explicit about the role of inductive biases and (implicit) supervision,
investigate concrete benefits of enforcing disentanglement of the learned representations,
and consider a reproducible experimental setup covering several data sets."

text: Quantum illumination is a sensing technique that employs entangled signal-idler
beams to improve the detection efficiency of low-reflectivity objects in environments
with large thermal noise. The advantage over classical strategies is evident at
low signal brightness, a feature which could make the protocol an ideal prototype
for non-invasive scanning or low-power short-range radar. Here we experimentally
investigate the concept of quantum illumination at microwave frequencies, by generating
entangled fields using a Josephson parametric converter which are then amplified
to illuminate a room-temperature object at a distance of 1 meter. Starting from
experimental data, we simulate the case of perfect idler photon number detection,
which results in a quantum advantage compared to the relative classical benchmark.
Our results highlight the opportunities and challenges on the way towards a first
room-temperature application of microwave quantum circuits.

text: "Distributed ledgers provide high availability and integrity, making them
a key enabler for practical and secure computation of distributed workloads among
mutually distrustful parties. Many practical applications also require strong
confidentiality, however. This work enhances permissioned and permissionless blockchains
with the ability to manage confidential data without forfeiting availability or
decentralization. The proposed Calypso architecture addresses two orthogonal challenges
confronting modern distributed ledgers: (a) enabling the auditable management
of secrets and (b) protecting distributed computations against arbitrage attacks
when their results depend on the ordering and secrecy of inputs.\r\n\r\nCalypso
introduces on-chain secrets, a novel abstraction that enforces atomic deposition
of an auditable trace whenever users access confidential data. Calypso provides
user-controlled consent management that ensures revocation atomicity and accountable
anonymity. To enable permissionless deployment, we introduce an incentive scheme
and provide users with the option to select their preferred trustees. We evaluated
our Calypso prototype with a confidential document-sharing application and a decentralized
lottery. Our benchmarks show that transaction-processing latency increases linearly
in terms of security (number of trustees) and is in the range of 0.2 to 8 seconds
for 16 to 128 trustees."

text: We give a short and self-contained proof for rates of convergence of the Allen--Cahn
equation towards mean curvature flow, assuming that a classical (smooth) solution
to the latter exists and starting from well-prepared initial data. Our approach
is based on a relative entropy technique. In particular, it does not require a
stability analysis for the linearized Allen--Cahn operator. As our analysis also
does not rely on the comparison principle, we expect it to be applicable to more
complex equations and systems.

text: Machine learning and formal methods have complimentary benefits and drawbacks.
In this work, we address the controller-design problem with a combination of techniques
from both fields. The use of black-box neural networks in deep reinforcement learning
(deep RL) poses a challenge for such a combination. Instead of reasoning formally
about the output of deep RL, which we call the wizard, we extract from it a decision-tree
based model, which we refer to as the magic book. Using the extracted model as
an intermediary, we are able to handle problems that are infeasible for either
deep RL or formal methods by themselves. First, we suggest, for the first time,
a synthesis procedure that is based on a magic book. We synthesize a stand-alone
correct-by-design controller that enjoys the favorable performance of RL. Second,
we incorporate a magic book in a bounded model checking (BMC) procedure. BMC allows
us to find numerous traces of the plant under the control of the wizard, which
a user can use to increase the trustworthiness of the wizard and direct further
training.

text: 'The fundamental and practical importance of particle stabilization has motivated
various characterization methods for studying polymer brushes on particle surfaces.
In this work, we show how one can perform sensitive measurements of neutral polymer
coating on colloidal particles using a commercial zetameter and salt solutions.
By systematically varying the Debye length, we study the mobility of the polymer-coated
particles in an applied electric field and show that the electrophoretic mobility
of polymer-coated particles normalized by the mobility of non-coated particles
is entirely controlled by the polymer brush and independent of the native surface
charge, here controlled with pH, or the surface–ion interaction. Our result is
rationalized with a simple hydrodynamic model, allowing for the estimation of
characteristics of the polymer coating: the brush length L, and the Brinkman length
ξ, determined by its resistance to flows. We demonstrate that the Debye layer
provides a convenient and faithful probe to the characterization of polymer coatings
on particles. Because the method simply relies on a conventional zetameter, it
is widely accessible and offers a practical tool to rapidly probe neutral polymer
brushes, an asset in the development and utilization of polymer-coated colloidal
particles.'

text: 'From rock salt to nanoparticle superlattices, complex structure can emerge
from simple building blocks that attract each other through Coulombic forces1-4.
On the micrometre scale, however, colloids in water defy the intuitively simple
idea of forming crystals from oppositely charged partners, instead forming non-equilibrium
structures such as clusters and gels5-7. Although various systems have been engineered
to grow binary crystals8-11, native surface charge in aqueous conditions has not
been used to assemble crystalline materials. Here we form ionic colloidal crystals
in water through an approach that we refer to as polymer-attenuated Coulombic
self-assembly. The key to crystallization is the use of a neutral polymer to keep
particles separated by well defined distances, allowing us to tune the attractive
overlap of electrical double layers, directing particles to disperse, crystallize
or become permanently fixed on demand. The nucleation and growth of macroscopic
single crystals is demonstrated by using the Debye screening length to fine-tune
assembly. Using a variety of colloidal particles and commercial polymers, ionic
colloidal crystals isostructural to caesium chloride, sodium chloride, aluminium
diboride and K4C60 are selected according to particle size ratios. Once fixed
by simply diluting out solution salts, crystals are pulled out of the water for
further manipulation, demonstrating an accurate translation from solution-phase
assembly to dried solid structures. In contrast to other assembly approaches,
in which particles must be carefully engineered to encode binding information12-18,
polymer-attenuated Coulombic self-assembly enables conventional colloids to be
used as model colloidal ions, primed for crystallization. '

text: Gadolinium silicide (Gd5Si4) nanoparticles are an interesting class of materials
due to their high magnetization, low Curie temperature, low toxicity in biological
environments and their multifunctional properties. We report the magnetic and
magnetothermal properties of gadolinium silicide (Gd5Si4) nanoparticles prepared
by surfactant-assisted ball milling of arc melted bulk ingots of the compound.
Using different milling times and speeds, a wide range of crystallite sizes (13–43
nm) could be produced and a reduction in Curie temperature (TC) from 340 K to
317 K was achieved, making these nanoparticles suitable for self-controlled magnetic
hyperthermia applications. The magnetothermal effect was measured in applied AC
magnetic fields of amplitude 164–239 Oe and frequencies 163–519 kHz. All particles
showed magnetic heating with a strong dependence of the specific absorption rate
(SAR) on the average crystallite size. The highest SAR of 3.7 W g−1 was measured
for 43 nm sized nanoparticles of Gd5Si4. The high SAR and low TC, (within the
therapeutic range for magnetothermal therapy) makes the Gd5Si4 behave like self-regulating
heat switches that would be suitable for self-controlled magnetic hyperthermia
applications after biocompatibility and cytotoxicity tests.

text: In the quest for alternate and efficient electrode materials, ternary metal
electrocatalysts (TMEs), part of the perovskite family, were synthesized and tested
for methanol electro-oxidation in alkaline media. La0.5Ca0.5MO3 (M = Ni, Co, or
Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that
the perovskite crystal structure possesses characteristic sharp and crystalline
peaks for all synthesized ternary electrocatalysts. The average particle size
calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO)
> La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as
prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The
qualitative and quantitative analysis revealed the presence of La, Ca and Co in
parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82%
respectively. The particle size distribution was homogenous, as determined by
scanning electron and transmission electron microscopes. The electrocatalytic
activity of the synthesized ternary electrocatalysts was studied electrochemically
by cyclic voltammetry. The calculated diffusion coefficient values showed that
electrode surface of LCNO and LCCO have limited efficiency for diffusion related
phenomenon. The heterogeneous rate constants inferred better electrode kinetics
of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic
peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V,
respectively. Methanol electro-oxidation was found minimal in case of LCMO sample.
We have observed that Co substitution at B-site of perovskite electrode materials
attains better electrochemical properties, thus in relation with reported literature.

text: 'We introduce LRT-NG, a set of techniques and an associated toolset that computes
a reachtube (an over-approximation of the set of reachable states over a given
time horizon) of a nonlinear dynamical system. LRT-NG significantly advances the
state-of-the-art Langrangian Reachability and its associated tool LRT. From a
theoretical perspective, LRT-NG is superior to LRT in three ways. First, it uses
for the first time an analytically computed metric for the propagated ball which
is proven to minimize the ball’s volume. We emphasize that the metric computation
is the centerpiece of all bloating-based techniques. Secondly, it computes the
next reachset as the intersection of two balls: one based on the Cartesian metric
and the other on the new metric. While the two metrics were previously considered
opposing approaches, their joint use considerably tightens the reachtubes. Thirdly,
it avoids the "wrapping effect" associated with the validated integration of the
center of the reachset, by optimally absorbing the interval approximation in the
radius of the next ball. From a tool-development perspective, LRT-NG is superior
to LRT in two ways. First, it is a standalone tool that no longer relies on CAPD.
This required the implementation of the Lohner method and a Runge-Kutta time-propagation
method. Secondly, it has an improved interface, allowing the input model and initial
conditions to be provided as external input files. Our experiments on a comprehensive
set of benchmarks, including two Neural ODEs, demonstrates LRT-NG’s superior performance
compared to LRT, CAPD, and Flow*.'

text: We consider the free additive convolution of two probability measures μ and
ν on the real line and show that μ ⊞ v is supported on a single interval if μ
and ν each has single interval support. Moreover, the density of μ ⊞ ν is proven
to vanish as a square root near the edges of its support if both μ and ν have
power law behavior with exponents between −1 and 1 near their edges. In particular,
these results show the ubiquity of the conditions in our recent work on optimal
local law at the spectral edges for addition of random matrices [5].

text: "Microwave photonics lends the advantages of fiber optics to electronic sensing
and communication systems. In contrast to nonlinear optics, electro-optic devices
so far require classical modulation fields whose variance is dominated by electronic
or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional
single-sideband conversion of X band microwave to C band telecom light with a
microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of
less than or equal to 0.074 photons. This is facilitated by radiative cooling
and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures.
The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency
of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output
noise photons per second for the highest available pump power of 1.48 mW puts
near-unity efficiency pulsed quantum transduction within reach. Together with
the non-Gaussian resources of superconducting qubits this might provide the practical
foundation to extend the range and scope of current quantum networks in analogy
to electrical repeaters in classical fiber optic communication."

text: 'Inversions are chromosomal rearrangements where the order of genes is reversed.
Inversions originate by mutation and can be under positive, negative or balancing
selection. Selective effects result from potential disruptive effects on meiosis,
gene disruption at inversion breakpoints and, importantly, the effects of inversions
as modifiers of recombination rate: Recombination is strongly reduced in individuals
heterozygous for an inversion, allowing for alleles at different loci to be inherited
as a ‘block’. This may lead to a selective advantage whenever it is favourable
to keep certain combinations of alleles associated, for example under local adaptation
with gene flow. Inversions can cover a considerable part of a chromosome and contain
numerous loci under different selection pressures, so that the resulting overall
effects may be complex. Empirical data from various systems show that inversions
may have a prominent role in local adaptation, speciation, parallel evolution,
the maintenance of polymorphism and sex chromosome evolution.'

text: The couplings among clouds, convection, and circulation in trade-wind regimes
remain a fundamental puzzle that limits our ability to constrain future climate
change. Radiative heating plays an important role in these couplings. Here we
calculate the clear-sky radiative profiles from 2001 in-situ soundings (978 dropsondes
and 1023 radiosondes) collected during the EUREC4A field campaign, which took
place south and east of Barbados in January–February 2020. We describe the method
used to calculate these radiative profiles and present preliminary results sampling
variability at multiple scales, from the variability across all soundings to groupings
by diurnal cycle and mesoscale organization state, as well as individual soundings
associated with elevated moisture layers. This clear-sky radiative profiles data
set can provide important missing detail to what can be learned from calculations
based on passive remote sensing and help in investigating the role of radiation
in dynamic and thermodynamic variability in trade-wind regimes. All data are archived
and freely available for public access on AERIS (Albright et al. (2020), https://doi.org/10.25326/78).

text: This study investigates the feedbacks between an interactive sea surface temperature
(SST) and the self‐aggregation of deep convective clouds, using a cloud‐resolving
model in nonrotating radiative‐convective equilibrium. The ocean is modeled as
one layer slab with a temporally fixed mean but spatially varying temperature.
We find that the interactive SST decelerates the aggregation and that the deceleration
is larger with a shallower slab, consistent with earlier studies. The surface
temperature anomaly in dry regions is positive at first, thus opposing the diverging
shallow circulation known to favor self‐aggregation, consistent with the slower
aggregation. But surprisingly, the driest columns then have a negative SST anomaly,
thus strengthening the diverging shallow circulation and favoring aggregation.
This diverging circulation out of dry regions is found to be well correlated with
the aggregation speed. It can be linked to a positive surface pressure anomaly
(PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling.
The latter cools and dries the boundary layer, thus increasing PSFC anomalies
through virtual effects and hydrostasy. Sensitivity experiments confirm the key
role played by boundary layer radiative cooling in determining PSFC anomalies
in dry regions, and thus the shallow diverging circulation and the aggregation
speed.

text: The goal of this study is to understand the mechanisms controlling the isotopic
composition of the water vapor near the surface of tropical oceans, at the scale
of about a hundred kilometers and a month. In the tropics, it has long been observed
that the isotopic compositions of rain and vapor near the surface are more depleted
when the precipitation rate is high. This is called the “amount effect.” Previous
studies, based on observations or models with parameterized convection, have highlighted
the roles of deep convective and mesoscale downdrafts and rain evaporation. But
the relative importance of these processes has never been quantified. We hypothesize
that it can be quantified using an analytical model constrained by large‐eddy
simulations. Results from large‐eddy simulations confirm that the classical amount
effect can be simulated only if precipitation rate changes result from changes
in the large‐scale circulation. We find that the main process depleting the water
vapor compared to the equilibrium with the ocean is the fact that updrafts stem
from areas where the water vapor is more enriched. The main process responsible
for the amount effect is the fact that when the large‐scale ascent increases,
isotopic vertical gradients are steeper, so that updrafts and downdrafts deplete
the subcloud layer more efficiently.
