text: "A central problem in computational statistics is to convert a procedure for
sampling combinatorial objects into a procedure for counting those objects, and
vice versa. We will consider sampling problems which come from Gibbs distributions,
which are families of probability distributions over a discrete space Ω with probability
mass function of the form μ^Ω_β(ω) ∝ e^{β H(ω)} for β in an interval [β_min, β_max]
and H(ω) ∈ {0} ∪ [1, n].\r\nThe partition function is the normalization factor
Z(β) = ∑_{ω ∈ Ω} e^{β H(ω)}, and the log partition ratio is defined as q = (log
Z(β_max))/Z(β_min)\r\nWe develop a number of algorithms to estimate the counts
c_x using roughly Õ(q/ε²) samples for general Gibbs distributions and Õ(n²/ε²)
samples for integer-valued distributions (ignoring some second-order terms and
parameters), We show this is optimal up to logarithmic factors. We illustrate
with improved algorithms for counting connected subgraphs and perfect matchings
in a graph."
acknowledgement: We thank Heng Guo for helpful explanations of algorithms for sampling
connected subgraphs and matchings, Maksym Serbyn for bringing to our attention the
Wang-Landau algorithm and its use in physics.

text: "The maximization of submodular functions have found widespread application
in areas such as machine learning, combinatorial optimization, and economics,
where practitioners often wish to enforce various constraints; the matroid constraint
has been investigated extensively due to its algorithmic properties and expressive
power. Though tight approximation algorithms for general matroid constraints exist
in theory, the running times of such algorithms typically scale quadratically,
and are not practical for truly large scale settings. Recent progress has focused
on fast algorithms for important classes of matroids given in explicit form. Currently,
nearly-linear time algorithms only exist for graphic and partition matroids [Alina
Ene and Huy L. Nguyen, 2019]. In this work, we develop algorithms for monotone
submodular maximization constrained by graphic, transversal matroids, or laminar
matroids in time near-linear in the size of their representation. Our algorithms
achieve an optimal approximation of 1-1/e-ε and both generalize and accelerate
the results of Ene and Nguyen [Alina Ene and Huy L. Nguyen, 2019]. In fact, the
running time of our algorithm cannot be improved within the fast continuous greedy
framework of Badanidiyuru and Vondrák [Ashwinkumar Badanidiyuru and Jan Vondrák,
2014].\r\nTo achieve near-linear running time, we make use of dynamic data structures
that maintain bases with approximate maximum cardinality and weight under certain
element updates. These data structures need to support a weight decrease operation
and a novel Freeze operation that allows the algorithm to freeze elements (i.e.
force to be contained) in its basis regardless of future data structure operations.
For the laminar matroid, we present a new dynamic data structure using the top
tree interface of Alstrup, Holm, de Lichtenberg, and Thorup [Stephen Alstrup et
al., 2005] that maintains the maximum weight basis under insertions and deletions
of elements in O(log n) time. This data structure needs to support certain subtree
query and path update operations that are performed every insertion and deletion
that are non-trivial to handle in conjunction. For the transversal matroid the
Freeze operation corresponds to requiring the data structure to keep a certain
set S of vertices matched, a property that we call S-stability. While there is
a large body of work on dynamic matching algorithms, none are S-stable and maintain
an approximate maximum weight matching under vertex updates. We give the first
such algorithm for bipartite graphs with total running time linear (up to log
factors) in the number of edges."

text: Polar active matter of self-propelled particles sustain spontaneous flows
through the full-integer topological defects. We study theoretically the incompressible
flow profiles around ±1 defects induced by polar and dipolar active forces. We
show that dipolar forces induce vortical flows around the +1 defect, while the
flow around the −1 defect has an 8-fold rotational symmetry. The vortical flow
changes its chirality near the +1 defect core in the absence of the friction with
a substrate. We show analytically that the flow induced by polar active forces
is vortical near the +1 defect and is 4-fold symmetric near the −1 defect, while
it becomes uniform in the far-field. For a pair of oppositely charged defects,
this polar flow contributes to a mutual interaction force that depends only on
the orientation of the defect pair relative to the background polarization, and
that enhances defect pair annihilation. This is in contradiction with the effect
of dipolar active forces which decay inversely proportional with the defect separation
distance. As such, our analyses reveals a long-ranged mechanism for the pairwise
interaction between topological defects in polar active matter.

text: For the Fröhlich model of the large polaron, we prove that the ground state
energy as a function of the total momentum has a unique global minimum at momentum
zero. This implies the non-existence of a ground state of the translation invariant
Fröhlich Hamiltonian and thus excludes the possibility of a localization transition
at finite coupling.

text: CLIP proved that aligning visual and language spaces is key to solving many
vision tasks without explicit training, but required to train image and text encoders
from scratch on a huge dataset. LiT improved this by only training the text encoder
and using a pre-trained vision network. In this paper, we show that a common space
can be created without any training at all, using single-domain encoders (trained
with or without supervision) and a much smaller amount of image-text pairs. Furthermore,
our model has unique properties. Most notably, deploying a new version with updated
training samples can be done in a matter of seconds. Additionally, the representations
in the common space are easily interpretable as every dimension corresponds to
the similarity of the input to a unique entry in the multimodal dataset. Experiments
on standard zero-shot visual benchmarks demonstrate the typical transfer ability
of image-text models. Overall, our method represents a simple yet surprisingly
strong baseline for foundation multi-modal models, raising important questions
on their data efficiency and on the role of retrieval in machine learning.

text: We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of
a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared
laser pulse. The time-dependent degree of alignment measured, exhibits a periodic,
gradually decreasing structure that deviates qualitatively from that expected
for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent
rotational Schrödinger equation shows that the deviation is due to the alignment
dependent interaction between the dimer and the droplet surface. This interaction
confines the dimer to the tangential plane of the droplet surface at the point
where it resides and is the reason that the observed alignment dynamics is also
well described by a 2D quantum rotor model.

text: "Given a resolution of rational singularities π:X~→X over a field of characteristic
zero, we use a Hodge-theoretic argument to prove that the image of the functor
\ Rπ∗:Db(X~)→Db(X)\r\n between bounded derived categories of coherent sheaves
generates Db(X)\r\n as a triangulated category. This gives a weak version of
the Bondal–Orlov localization conjecture [BO02], answering a question from [PS21].
The same result is established more generally for proper (not necessarily birational)

text: This paper introduces a novel method for simulating large bodies of water
as a height field. At the start of each time step, we partition the waves into
a bulk flow (which approximately satisfies the assumptions of the shallow water
equations) and surface waves (which approximately satisfy the assumptions of Airy
wave theory). We then solve the two wave regimes separately using appropriate
state-of-the-art techniques, and re-combine the resulting wave velocities at the
end of each step. This strategy leads to the first heightfield wave model capable
of simulating complex interactions between both deep and shallow water effects,
like the waves from a boat wake sloshing up onto a beach, or a dam break producing
wave interference patterns and eddies. We also analyze the numerical dispersion
created by our method and derive an exact correction factor for waves at a constant
water depth, giving us a numerically perfect re-creation of theoretical water
wave dispersion patterns.

text: We present a technique to optimize the reflectivity of a surface while preserving
its overall shape. The naïve optimization of the mesh vertices using the gradients
of reflectivity simulations results in undesirable distortion. In contrast, our
robust formulation optimizes the surface normal as an independent variable that
bridges the reflectivity term with differential rendering, and the regularization
term with as-rigid-as-possible elastic energy. We further adaptively subdivide
the input mesh to improve the convergence. Consequently, our method can minimize
the retroreflectivity of a wide range of input shapes, resulting in sharply creased
shapes ubiquitous among stealth aircraft and Sci-Fi vehicles. Furthermore, by
changing the reward for the direction of the outgoing light directions, our method
can be applied to other reflectivity design tasks, such as the optimization of
architectural walls to concentrate light in a specific region. We have tested
the proposed method using light-transport simulations and real-world 3D-printed
objects.

text: We study the problem of training and certifying adversarially robust quantized
neural networks (QNNs). Quantization is a technique for making neural networks
more efficient by running them using low-bit integer arithmetic and is therefore
commonly adopted in industry. Recent work has shown that floating-point neural
networks that have been verified to be robust can become vulnerable to adversarial
attacks after quantization, and certification of the quantized representation
is necessary to guarantee robustness. In this work, we present quantization-aware
interval bound propagation (QA-IBP), a novel method for training robust QNNs.
Inspired by advances in robust learning of non-quantized networks, our training
algorithm computes the gradient of an abstract representation of the actual network.
Unlike existing approaches, our method can handle the discrete semantics of QNNs.
Based on QA-IBP, we also develop a complete verification procedure for verifying
the adversarial robustness of QNNs, which is guaranteed to terminate and produce
a correct answer. Compared to existing approaches, the key advantage of our verification
procedure is that it runs entirely on GPU or other accelerator devices. We demonstrate
experimentally that our approach significantly outperforms existing methods and
establish the new state-of-the-art for training and certifying the robustness
of QNNs.

text: "In this paper, we determine the motivic class — in particular, the weight
polynomial and conjecturally the Poincaré polynomial — of the open de Rham space,
defined and studied by Boalch, of certain moduli spaces of irregular meromorphic
connections on the trivial rank \r\n bundle on P1. The computation is by motivic
Fourier transform. We show that the result satisfies the purity conjecture, that
is, it agrees with the pure part of the conjectured mixed Hodge polynomial of
the corresponding wild character variety. We also identify the open de Rham spaces
with quiver varieties with multiplicities of Yamakawa and Geiss–Leclerc–Schröer.
We finish with constructing natural complete hyperkähler metrics on them, which
in the four-dimensional cases are expected to be of type ALF."

of a coupling between gauge potentials and matter. The typical formulation of
the model is based upon a single particle picture, and should be extended when
interactions with other particles become relevant. Here, we illustrate such an
extension for a particle in an Aharonov-Bohm ring subject to interactions with
a weakly interacting Bose gas. We show that the ground state of the system can
be described using the Bose-polaron concept—a particle dressed by interactions
with a bosonic environment. We connect the energy spectrum to the effective mass
of the polaron, and demonstrate how to change currents in the system by tuning
boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform
for studying coherence and few- to many-body crossover of quasi-particles that
arise from an impurity immersed in a medium.

text: Junctions between the endoplasmic reticulum (ER) and the plasma membrane (PM)
are specialized membrane contacts ubiquitous in eukaryotic cells. Concentration
of intracellular signaling machinery near ER-PM junctions allows these domains
to serve critical roles in lipid and Ca2+ signaling and homeostasis. Subcellular
compartmentalization of protein kinase A (PKA) signaling also regulates essential
cellular functions, however, no specific association between PKA and ER-PM junctional
domains is known. Here, we show that in brain neurons type I PKA is directed to
Kv2.1 channel-dependent ER-PM junctional domains via SPHKAP, a type I PKA-specific
anchoring protein. SPHKAP association with type I PKA regulatory subunit RI and
ER-resident VAP proteins results in the concentration of type I PKA between stacked
ER cisternae associated with ER-PM junctions. This ER-associated PKA signalosome
enables reciprocal regulation between PKA and Ca2+ signaling machinery to support
Ca2+ influx and excitation-transcription coupling. These data reveal that neuronal
ER-PM junctions support a receptor-independent form of PKA signaling driven by
membrane depolarization and intracellular Ca2+, allowing conversion of information
encoded in electrical signals into biochemical changes universally recognized
throughout the cell.

text: In [10] Nam proved a Lieb–Thirring Inequality for the kinetic energy of a
fermionic quantum system, with almost optimal (semi-classical) constant and a
gradient correction term. We present a stronger version of this inequality, with
a much simplified proof. As a corollary we obtain a simple proof of the original
Lieb–Thirring inequality.

text: Toscana virus is a major cause of arboviral disease in humans in the Mediterranean
basin during summer. However, early virus-host cell interactions and entry mechanisms
remain poorly characterized. Investigating iPSC-derived human neurons and cell
lines, we found that virus binding to the cell surface was specific, and 50% of
bound virions were endocytosed within 10 min. Virions entered Rab5a+ early endosomes
and, subsequently, Rab7a+ and LAMP-1+ late endosomal compartments. Penetration
required intact late endosomes and occurred within 30 min following internalization.
Virus entry relied on vacuolar acidification, with an optimal pH for viral membrane
fusion at pH 5.5. The pH threshold increased to 5.8 with longer pre-exposure of
virions to the slightly acidic pH in early endosomes. Strikingly, the particles
remained infectious after entering late endosomes with a pH below the fusion threshold.
Overall, our study establishes Toscana virus as a late-penetrating virus and reveals
an atypical use of vacuolar acidity by this virus to enter host cells.

text: There is currently little evidence that the genetic basis of human phenotype
varies significantly across the lifespan. However, time-to-event phenotypes are
understudied and can be thought of as reflecting an underlying hazard, which is
unlikely to be constant through life when values take a broad range. Here, we
find that 74% of 245 genome-wide significant genetic associations with age at
natural menopause (ANM) in the UK Biobank show a form of age-specific effect.
Nineteen of these replicated discoveries are identified only by our modeling framework,
which determines the time dependency of DNA-variant age-at-onset associations
without a significant multiple-testing burden. Across the range of early to late
menopause, we find evidence for significantly different underlying biological
pathways, changes in the signs of genetic correlations of ANM to health indicators
and outcomes, and differences in inferred causal relationships. We find that DNA
damage response processes only act to shape ovarian reserve and depletion for
women of early ANM. Genetically mediated delays in ANM were associated with increased
relative risk of breast cancer and leiomyoma at all ages and with high cholesterol
and heart failure for late-ANM women. These findings suggest that a better understanding
of the age dependency of genetic risk factor relationships among health indicators
and outcomes is achievable through appropriate statistical modeling of large-scale
biobank data.

text: In this work, a generalized, adapted Numerov implementation capable of determining
band structures of periodic quantum systems is outlined. Based on the input potential,
the presented approach numerically solves the Schrödinger equation in position
space at each momentum space point. Thus, in addition to the band structure, the
method inherently provides information about the state functions and probability
densities in position space at each momentum space point considered. The generalized,
adapted Numerov framework provided reliable estimates for a variety of increasingly
complex test suites in one, two, and three dimensions. The accuracy of the proposed
methodology was benchmarked against results obtained for the analytically solvable
Kronig-Penney model. Furthermore, the presented numerical solver was applied to
a model potential representing a 2D optical lattice being a challenging application
relevant, for example, in the field of quantum computing.

text: Living tissues are characterized by an intrinsically mechanochemical interplay
of active physical forces and complex biochemical signaling pathways. Either feature
alone can give rise to complex emergent phenomena, for example, mechanically driven
glassy dynamics and rigidity transitions, or chemically driven reaction-diffusion
instabilities. An important question is how to quantitatively assess the contribution
of these different cues to the large-scale dynamics of biological materials. We
address this in Madin-Darby canine kidney (MDCK) monolayers, considering both
mechanochemical feedback between extracellular signal-regulated kinase (ERK) signaling
activity and cellular density as well as a mechanically active tissue rheology
via a self-propelled vertex model. We show that the relative strength of active
migration forces to mechanochemical couplings controls a transition from a uniform
active glass to periodic spatiotemporal waves. We parametrize the model from published
experimental data sets on MDCK monolayers and use it to make new predictions on
the correlation functions of cellular dynamics and the dynamics of topological
defects associated with the oscillatory phase of cells. Interestingly, MDCK monolayers
are best described by an intermediary parameter region in which both mechanochemical
couplings and noisy active propulsion have a strong influence on the dynamics.
Finally, we study how tissue rheology and ERK waves produce feedback on one another
and uncover a mechanism via which tissue fluidity can be controlled by mechanochemical
waves at both the local and global levels.
