text: We present the first sublinear-time algorithm that can compute the edge connectivity
λ of a network exactly on distributed message-passing networks (the CONGEST model),
as long as the network contains no multi-edge. We present the first sublinear-time
algorithm for a distributed message-passing network sto compute its edge connectivity
λ exactly in the CONGEST model, as long as there are no parallel edges. Our algorithm
takes Õ(n1−1/353D1/353+n1−1/706) time to compute λ and a cut of cardinality λ
with high probability, where n and D are the number of nodes and the diameter
of the network, respectively, and Õ hides polylogarithmic factors. This running
time is sublinear in n (i.e. Õ(n1−є)) whenever D is. Previous sublinear-time distributed
algorithms can solve this problem either (i) exactly only when λ=O(n1/8−є) [Thurimella
PODC’95; Pritchard, Thurimella, ACM Trans. Algorithms’11; Nanongkai, Su, DISC’14]
or (ii) approximately [Ghaffari, Kuhn, DISC’13; Nanongkai, Su, DISC’14]. To achieve
this we develop and combine several new techniques. First, we design the first
distributed algorithm that can compute a k-edge connectivity certificate for any
k=O(n1−є) in time Õ(√nk+D). The previous sublinear-time algorithm can do so only
when k=o(√n) [Thurimella PODC’95]. In fact, our algorithm can be turned into the
first parallel algorithm with polylogarithmic depth and near-linear work. Previous
near-linear work algorithms are essentially sequential and previous polylogarithmic-depth
algorithms require Ω(mk) work in the worst case (e.g. [Karger, Motwani, STOC’93]).
Second, we show that by combining the recent distributed expander decomposition
technique of [Chang, Pettie, Zhang, SODA’19] with techniques from the sequential
deterministic edge connectivity algorithm of [Kawarabayashi, Thorup, STOC’15],
we can decompose the network into a sublinear number of clusters with small average
diameter and without any mincut separating a cluster (except the “trivial” ones).
This leads to a simplification of the Kawarabayashi-Thorup framework (except that
we are randomized while they are deterministic). This might make this framework
more useful in other models of computation. Finally, by extending the tree packing
technique from [Karger STOC’96], we can find the minimum cut in time proportional
to the number of components. As a byproduct of this technique, we obtain an Õ(n)-time
algorithm for computing exact minimum cut for weighted graphs.

text: "Many dynamic graph algorithms have an amortized update time, rather than
a stronger worst-case guarantee. But amortized data structures are not suitable
for real-time systems, where each individual operation has to be executed quickly.
For this reason, there exist many recent randomized results that aim to provide
a guarantee stronger than amortized expected. The strongest possible guarantee
for a randomized algorithm is that it is always correct (Las Vegas), and has high-probability
worst-case update time, which gives a bound on the time for each individual operation
that holds with high probability.\r\n\r\nIn this paper we present the first polylogarithmic
high-probability worst-case time bounds for the dynamic spanner and the dynamic
maximal matching problem.\r\n\r\n1.\t\r\nFor dynamic spanner, the only known o(n)
worst-case bounds were O(n3/4) high-probability worst-case update time for maintaining
a 3-spanner, and O(n5/9) for maintaining a 5-spanner. We give a O(1)k log3(n)
high-probability worst-case time bound for maintaining a (2k – 1)-spanner, which
yields the first worst-case polylog update time for all constant k. (All the results
above maintain the optimal tradeoff of stretch 2k – 1 and Õ(n1+1/k) edges.)\r\n\r\n2.\t\r\nFor
dynamic maximal matching, or dynamic 2-approximate maximum matching, no algorithm
with o(n) worst-case time bound was known and we present an algorithm with O(log5
(n)) high-probability worst-case time; similar worst-case bounds existed only
for maintaining a matching that was (2 + ∊)-approximate, and hence not maximal.\r\n\r\nOur
results are achieved using a new approach for converting amortized guarantees
to worst-case ones for randomized data structures by going through a third type
of guarantee, which is a middle ground between the two above: an algorithm is
said to have worst-case expected update time α if for every update σ, the expected
time to process σ is at most α. Although stronger than amortized expected, the
worst-case expected guarantee does not resolve the fundamental problem of amortization:
a worst-case expected update time of O(1) still allows for the possibility that
every 1/f(n) updates requires Θ(f(n)) time to process, for arbitrarily high f(n).
In this paper we present a black-box reduction that converts any data structure
with worst-case expected update time into one with a high-probability worst-case
update time: the query time remains the same, while the update time increases
by a factor of O(log2(n)).\r\n\r\nThus we achieve our results in two steps: (1)
First we show how to convert existing dynamic graph algorithms with amortized
expected polylogarithmic running times into algorithms with worst-case expected
polylogarithmic running times. (2) Then we use our black-box reduction to achieve
the polylogarithmic high-probability worst-case time bound. All our algorithms
are Las-Vegas-type algorithms."

text: "We build upon the recent papers by Weinstein and Yu (FOCS'16), Larsen (FOCS'12),
and Clifford et al. (FOCS'15) to present a general framework that gives amortized
lower bounds on the update and query times of dynamic data structures. Using our
framework, we present two concrete results.\r\n(1) For the dynamic polynomial
evaluation problem, where the polynomial is defined over a finite field of size
n1+Ω(1) and has degree n, any dynamic data structure must either have an amortized
update time of Ω((lgn/lglgn)2) or an amortized query time of Ω((lgn/lglgn)2).\r\n(2)
For the dynamic online matrix vector multiplication problem, where we get an n×n
matrix whose entires are drawn from a finite field of size nΘ(1), any dynamic
data structure must either have an amortized update time of Ω((lgn/lglgn)2) or
an amortized query time of Ω(n⋅(lgn/lglgn)2).\r\nFor these two problems, the previous
works by Larsen (FOCS'12) and Clifford et al. (FOCS'15) gave the same lower bounds,
but only for worst case update and query times. Our bounds match the highest unconditional
lower bounds known till date for any dynamic problem in the cell-probe model."

text: Cross-coupling reactions mediated by dual nickel/photocatalysis are synthetically
attractive but rely mainly on expensive, non-recyclable noble-metal complexes
as photocatalysts. Heterogeneous semiconductors, which are commonly used for artificial
photosynthesis and wastewater treatment, are a sustainable alternative. Graphitic
carbon nitrides, a class of metal-free polymers that can be easily prepared from
bulk chemicals, are heterogeneous semiconductors with high potential for photocatalytic
organic transformations. Here, we demonstrate that graphitic carbon nitrides in
combination with nickel catalysis can induce selective C−O cross-couplings of
carboxylic acids with aryl halides, yielding the respective aryl esters in excellent
yield and selectivity. The heterogeneous organic photocatalyst exhibits a broad
substrate scope, is able to harvest green light, and can be recycled multiple
times. In situ FTIR was used to track the reaction progress to study this transformation
at different irradiation wavelengths and reaction scales.

text: A carbon nitride material can be combined with homogeneous nickel catalysts
for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions.
The metal-free heterogeneous semiconductor is fully recyclable and couples a broad
range of electron-poor aryl bromides with primary and secondary alcohols as well
as water. The application for intramolecular reactions and the synthesis of active
pharmaceutical ingredients was demonstrated. The catalytic protocol is applicable
for the coupling of aryl iodides with thiols as well.

text: Differentially protected galactosamine building blocks are key components
for the synthesis of human and bacterial oligosaccharides. The azidophenylselenylation
of 3,4,6-tri-O-acetyl-d-galactal provides straightforward access to the corresponding
2-nitrogenated glycoside. Poor reproducibility and the use of azides that lead
to the formation of potentially explosive and toxic species limit the scalability
of this reaction and render it a bottleneck for carbohydrate synthesis. Here,
we present a method for the safe, efficient, and reliable azidophenylselenylation
of 3,4,6-tri-O-acetyl-d-galactal at room temperature, using continuous flow chemistry.
Careful analysis of the transformation resulted in reaction conditions that produce
minimal side products while the reaction time was reduced drastically when compared
to batch reactions. The flow setup is readily scalable to process 5 mmol of galactal
in 3 h, producing 1.2 mmol/h of product.

text: The cerebral cortex is composed of a large variety of distinct cell-types
including projection neurons, interneurons and glial cells which emerge from distinct
neural stem cell (NSC) lineages. The vast majority of cortical projection neurons
and certain classes of glial cells are generated by radial glial progenitor cells
(RGPs) in a highly orchestrated manner. Recent studies employing single cell analysis
and clonal lineage tracing suggest that NSC and RGP lineage progression are regulated
in a profound deterministic manner. In this review we focus on recent advances
based mainly on correlative phenotypic data emerging from functional genetic studies
in mice. We establish hypotheses to test in future research and outline a conceptual
framework how epigenetic cues modulate the generation of cell-type diversity during
cortical development. This article is protected by copyright. All rights reserved.

text: We study spaces of modelled distributions with singular behaviour near the
boundary of a domain that, in the context of the theory of regularity structures,
allow one to give robust solution theories for singular stochastic PDEs with boundary
conditions. The calculus of modelled distributions established in Hairer (Invent
Math 198(2):269–504, 2014. https://doi.org/10.1007/s00222-014-0505-4) is extended
to this setting. We formulate and solve fixed point problems in these spaces with
a class of kernels that is sufficiently large to cover in particular the Dirichlet
and Neumann heat kernels. These results are then used to provide solution theories
for the KPZ equation with Dirichlet and Neumann boundary conditions and for the
2D generalised parabolic Anderson model with Dirichlet boundary conditions. In
the case of the KPZ equation with Neumann boundary conditions, we show that, depending
on the class of mollifiers one considers, a “boundary renormalisation” takes place.
In other words, there are situations in which a certain boundary condition is
applied to an approximation to the KPZ equation, but the limiting process is the
Hopf–Cole solution to the KPZ equation with a different boundary condition.

text: We consider real symmetric or complex hermitian random matrices with correlated
entries. We prove local laws for the resolvent and universality of the local eigenvalue
statistics in the bulk of the spectrum. The correlations have fast decay but are
otherwise of general form. The key novelty is the detailed stability analysis
of the corresponding matrix valued Dyson equation whose solution is the deterministic

text: "We count points over a finite field on wild character varieties,of Riemann
surfaces for singularities with regular semisimple leading term. The new feature
in our counting formulas is the appearance of characters of Yokonuma–Hecke algebras.
Our result leads to the conjecture that the mixed Hodge polynomials of these character
varieties agree with previously conjectured perverse Hodge polynomials of certain
twisted parabolic Higgs moduli spaces, indicating the\r\npossibility of a P =
W conjecture for a suitable wild Hitchin system."

text: In this paper, we introduce a quantum version of the wonderful compactification
of a group as a certain noncommutative projective scheme. Our approach stems from
the fact that the wonderful compactification encodes the asymptotics of matrix
coefficients, and from its realization as a GIT quotient of the Vinberg semigroup.
In order to define the wonderful compactification for a quantum group, we adopt
a generalized formalism of Proj categories in the spirit of Artin and Zhang. Key
to our construction is a quantum version of the Vinberg semigroup, which we define
as a q-deformation of a certain Rees algebra, compatible with a standard Poisson
structure. Furthermore, we discuss quantum analogues of the stratification of
the wonderful compactification by orbits for a certain group action, and provide
explicit computations in the case of SL2.

text: "Two generalizations of Itô formula to infinite-dimensional spaces are given.\r\nThe
first one, in Hilbert spaces, extends the classical one by taking advantage of\r\ncancellations
when they occur in examples and it is applied to the case of a group\r\ngenerator.
The second one, based on the previous one and a limit procedure, is an Itô\r\nformula
in a special class of Banach spaces having a product structure with the noise\r\nin
a Hilbert component; again the key point is the extension due to a cancellation.
This\r\nextension to Banach spaces and in particular the specific cancellation
are motivated\r\nby path-dependent Itô calculus."

text: By investigating the in situ chemical and O-isotope compositions of olivine
in lightly sintered dust agglomerates from the early Solar System, we constrain
their origins and the retention of dust in the protoplanetary disk. The grain
sizes of silicates in these agglomeratic olivine (AO) chondrules indicate that
the grain sizes of chondrule precursors in the Renazzo-like carbonaceous (CR)
chondrites ranged from <1 to 80 µm. We infer this grain size range to be equivalent
to the size range for dust in the early Solar System. AO chondrules may contain,
but are not solely composed of, recycled fragments of earlier formed chondrules.
They also contain 16O-rich olivine related to amoeboid olivine aggregates and
represent the best record of chondrule-precursor materials. AO chondrules contain
one or more large grains, sometimes similar to FeO-poor (type I) and/or FeO-rich
(type II) chondrules, while others contain a type II chondrule core. These morphologies
are consistent with particle agglomeration by electrostatic charging of grains
during collision, a process that may explain solid agglomeration in the protoplanetary
disk in the micrometer size regime. The petrographic, isotopic, and chemical compositions
of AO chondrules are consistent with chondrule formation by large-scale shocks,
bow shocks, and current sheets. The petrographic, isotopic, and chemical similarities
between AO chondrules in CR chondrites and chondrule-like objects from comet 81P/Wild
2 indicate that comets contain AO chondrules. We infer that these AO chondrules
likely formed in the inner Solar System and migrated to the comet forming region
at least 3 Ma after the formation of the first Solar System solids. Observations
made in this study imply that the protoplanetary disk retained a dusty disk at
least ∼3.7 Ma after the formation of the first Solar System solids, longer than
half of the dusty accretion disks observed around other stars.

text: Many fields of study, including medical imaging, granular physics, colloidal
physics, and active matter, require the precise identification and tracking of
particle-like objects in images. While many algorithms exist to track particles
in diffuse conditions, these often perform poorly when particles are densely packed
together—as in, for example, solid-like systems of granular materials. Incorrect
particle identification can have significant effects on the calculation of physical
quantities, which makes the development of more precise and faster tracking algorithms
a worthwhile endeavor. In this work, we present a new tracking algorithm to identify
particles in dense systems that is both highly accurate and fast. We demonstrate
the efficacy of our approach by analyzing images of dense, solid-state granular
media, where we achieve an identification error of 5% in the worst evaluated cases.
Going further, we propose a parallelization strategy for our algorithm using a
GPU, which results in a speedup of up to 10× when compared to a sequential CPU
implementation in C and up to 40× when compared to the reference MATLAB library
widely used for particle tracking. Our results extend the capabilities of state-of-the-art
particle tracking methods by allowing fast, high-fidelity detection in dense media
at high resolutions.

text: The Leidenfrost effect occurs when a liquid or stiff sublimable solid near
a hot surface creates enough vapor beneath it to lift itself up and float. In
contrast, vaporizable soft solids, e.g., hydrogels, have been shown to exhibit
persistent bouncing - the elastic Leidenfrost effect. By carefully lowering hydrogel
spheres towards a hot surface, we discover that they are also capable of floating.
The bounce-to-float transition is controlled by the approach velocity and temperature,
analogously to the "dynamic Leidenfrost effect." For the floating regime,
we measure power-law scalings for the gap geometry, which we explain with a model
that couples the vaporization rate to the spherical shape. Our results reveal
that hydrogels are a promising pathway for controlling floating Leidenfrost objects
through shape.

text: We present a field-data rich modelling analysis to reconstruct the climatic
forcing, glacier response, and runoff generation from a high-elevation catchment
in central Chile over the period 2000–2015 to provide insights into the differing
contributions of debris-covered and debris-free glaciers under current and future
changing climatic conditions. Model simulations with the physically based glacio-hydrological
model TOPKAPI-ETH reveal a period of neutral or slightly positive mass balance
between 2000 and 2010, followed by a transition to increasingly large annual mass
losses, associated with a recent mega drought. Mass losses commence earlier, and
are more severe, for a heavily debris-covered glacier, most likely due to its
strong dependence on snow avalanche accumulation, which has declined in recent
years. Catchment runoff shows a marked decreasing trend over the study period,
but with high interannual variability directly linked to winter snow accumulation,
and high contribution from ice melt in dry periods and drought conditions. The
study demonstrates the importance of incorporating local-scale processes such
as snow avalanche accumulation and spatially variable debris thickness, in understanding
the responses of different glacier types to climate change. We highlight the increased
dependency of runoff from high Andean catchments on the diminishing resource of
glacier ice during dry years.

text: Glaciers in the high mountains of Asia provide an important water resource
for millions of people. Many of these glaciers are partially covered by rocky
debris, which protects the ice from solar radiation and warm air. However, studies
have found that the surface of these debris-covered glaciers is actually lowering
as fast as glaciers without debris. Water ponded on the surface of the glaciers
may be partially responsible, as water can absorb atmospheric energy very efficiently.
However, the overall effect of these ponds has not been thoroughly assessed yet.
We study a valley in Nepal for which we have extensive weather measurements, and
we use a numerical model to calculate the energy absorbed by ponds on the surface
of the glaciers over 6 months. As we have not observed each individual pond thoroughly,
we run the model 5,000 times with different setups. We find that ponds are extremely
important for glacier melt and absorb energy 14 times as quickly as the debris-covered
ice. Although the ponds account for 1% of the glacier area covered by rocks, and
only 0.3% of the total glacier area, they absorb enough energy to account for
one eighth of the whole valley's ice loss.
