text: "We study Multi-party computation (MPC) in the setting of subversion, where
the adversary tampers with the machines of honest parties. Our goal is to construct
actively secure MPC protocols where parties are corrupted adaptively by an adversary
(as in the standard adaptive security setting), and in addition, honest parties’
machines are compromised.\r\nThe idea of reverse firewalls (RF) was introduced
at EUROCRYPT’15 by Mironov and Stephens-Davidowitz as an approach to protecting
protocols against corruption of honest parties’ devices. Intuitively, an RF for
a party P is an external entity that sits between P and the outside world
and whose scope is to sanitize P ’s incoming and outgoing messages in the face
of subversion of their computer. Mironov and Stephens-Davidowitz constructed a
protocol for passively-secure two-party computation. At CRYPTO’20, Chakraborty,
Dziembowski and Nielsen constructed a protocol for secure computation with firewalls
that improved on this result, both by extending it to multi-party computation
protocol, and considering active security in the presence of static corruptions.
In this paper, we initiate the study of RF for MPC in the adaptive setting. We
put forward a definition for adaptively secure MPC in the reverse firewall setting,
explore relationships among the security notions, and then construct reverse firewalls
for MPC in this stronger setting of adaptive security. We also resolve the open
question of Chakraborty, Dziembowski and Nielsen by removing the need for a trusted
setup in constructing RF for MPC. Towards this end, we construct reverse firewalls
for adaptively secure augmented coin tossing and adaptively secure zero-knowledge
protocols and obtain a constant round adaptively secure MPC protocol in the reverse
firewall setting without setup. Along the way, we propose a new multi-party adaptively
secure coin tossing protocol in the plain model, that is of independent interest."

text: "Product graphs arise naturally in formal verification and program analysis.
For example, the analysis of two concurrent threads requires the product of two
component control-flow graphs, and for language inclusion of deterministic automata
the product of two automata is constructed. In many cases, the component graphs
have constant treewidth, e.g., when the input contains control-flow graphs of
programs. We consider the algorithmic analysis of products of two constant-treewidth
graphs with respect to three classic specification languages, namely, (a) algebraic
properties, (b) mean-payoff properties, and (c) initial credit for energy properties.\r\nOur
main contributions are as follows. Consider a graph G that is the product of two
constant-treewidth graphs of size n each. First, given an idempotent semiring,
we present an algorithm that computes the semiring transitive closure of G in
time Õ(n⁴). Since the output has size Θ(n⁴), our algorithm is optimal (up to
polylog factors). Second, given a mean-payoff objective, we present an O(n³)-time
algorithm for deciding whether the value of a starting state is non-negative,
improving the previously known O(n⁴) bound. Third, given an initial credit for
energy objective, we present an O(n⁵)-time algorithm for computing the minimum
initial credit for all nodes of G, improving the previously known O(n⁸) bound.
At the heart of our approach lies an algorithm for the efficient construction
of strongly-balanced tree decompositions of constant-treewidth graphs. Given a
constant-treewidth graph G' of n nodes and a positive integer λ, our algorithm
constructs a binary tree decomposition of G' of width O(λ) with the property that
the size of each subtree decreases geometrically with rate (1/2 + 2^{-λ})."

text: In the Intersection Non-emptiness problem, we are given a list of finite automata
A_1, A_2,… , A_m over a common alphabet Σ as input, and the goal is to determine
whether some string w ∈ Σ^* lies in the intersection of the languages accepted
by the automata in the list. We analyze the complexity of the Intersection Non-emptiness
problem under the promise that all input automata accept a language in some level
of the dot-depth hierarchy, or some level of the Straubing-Thérien hierarchy.
Automata accepting languages from the lowest levels of these hierarchies arise
naturally in the context of model checking. We identify a dichotomy in the dot-depth
hierarchy by showing that the problem is already NP-complete when all input automata
accept languages of the levels B_0 or B_{1/2} and already PSPACE-hard when all
automata accept a language from the level B_1. Conversely, we identify a tetrachotomy
in the Straubing-Thérien hierarchy. More precisely, we show that the problem is
in AC^0 when restricted to level L_0; complete for L or NL, depending on the input
representation, when restricted to languages in the level L_{1/2}; NP-complete
when the input is given as DFAs accepting a language in L_1 or L_{3/2}; and finally,
PSPACE-complete when the input automata accept languages in level L_2 or higher.
Moreover, we show that the proof technique used to show containment in NP for
DFAs accepting languages in L_1 or L_{3/2} does not generalize to the context
of NFAs. To prove this, we identify a family of languages that provide an exponential
separation between the state complexity of general NFAs and that of partially
ordered NFAs. To the best of our knowledge, this is the first superpolynomial
separation between these two models of computation.

text: "Civl is a static verifier for concurrent programs designed around the conceptual
framework of layered refinement,\r\nwhich views the task of verifying a program
as a sequence of program simplification steps each justified by its own invariant.
Civl verifies a layered concurrent program that compactly expresses all the programs
in this sequence and the supporting invariants. This paper presents the design
and implementation of the Civl verifier."

text: We experimentally investigate narrow and topologically nontrivial moiré minibands
hosted by van der Waals heterostructures consisting of a graphene monolayer rotationally
faulted with respect to a Bernal-stacked bilayer. At fillings ν= 1 and 3 electrons
per moiré unit cell within these bands, we observe quantized anomalous Hall effects
with Rxy≈h/2e2, indicative of spontaneous polarization of the system into a single
valley-projected band with Chern number C= 2. Remarkably, we also observe the
evidence of symmetry broken Chern insulator states at ν= 1.5 and 3.5. At ν= 3
we find that the sign of the quantum anomalous Hall effect can be reversed via
field-effect control of the chemical potential. This curious effect arises from
the magnetization contribution due to topological edge states, which drive a reversal
of the total magnetization and thus a switch of the favored magnetic state. Remarkably,
we find that this switch is hysteretic, which we use to demonstrate non-volatile
electric-field-induced reversal of the magnetic state. Voltage control of magnetic
states can be used to electrically pattern nonvolatile magnetic domain structures
hosting chiral edge states, with applications ranging from reconfigurable microwave
circuit elements to ultra-low-power magnetic memory.

text: 'The disks of active galactic nuclei (AGNs) have emerged as a rich environment
for the evolution of stars and their compact remnants. The very dense medium favors
rapid accretion, while torques and migration traps enhance binary formation and
mergers. Both long and short gamma-ray bursts are hence expected. We show that
AGN disks constitute an ideal environment for another interesting phenomenon:
the accretion-induced collapse (AIC) of neutron stars (NSs) to black holes (BHs).
Rapid accretion in the dense disks can cause NSs to grow to the point of exceeding
the maximum mass allowed by their equation of state. General relativistic magnetohydrodynamical
simulations have shown that electromagnetic signatures are expected if the NS
is surrounded by a minidisk prior to collapse, which then rapidly accretes onto
the BH, and/or if the NS is highly magnetized, from reconnection of the magnetosphere
during collapse. Here we compute the rates of AICs and their locations within
the disks for both isolated NSs and for (initially stable) NSs formed from NS-NS
mergers. We find that the global AIC rates are ∼0.07–20 Gpc−3 yr−1, and we discuss
their observable prospects and signatures as they emerge from the dense disk environments.'

text: The astrophysical origin of gravitational wave transients is a timely open
question in the wake of discoveries by the Laser Interferometer Gravitational-Wave
Observatory (LIGO)/Virgo. In active galactic nuclei (AGNs), binaries form and
evolve efficiently by interaction with a dense population of stars and the gaseous
AGN disk. Previous studies have shown that stellar-mass black hole (BH) mergers
in such environments can explain the merger rate and the number of suspected hierarchical
mergers observed by LIGO/Virgo. The binary eccentricity distribution can provide
further information to distinguish between astrophysical models. Here we derive
the eccentricity distribution of BH mergers in AGN disks. We find that eccentricity
is mainly due to binary–single (BS) interactions, which lead to most BH mergers
in AGN disks having a significant eccentricity at 0.01 Hz, detectable by the Laser
Interferometer Space Antenna. If BS interactions occur in isotropic-3D directions,
then 8%–30% of the mergers in AGN disks will have eccentricities at 10 Hz above
e10 Hz ≳ 0.03, detectable by LIGO/Virgo/Kamioka Gravitational Wave Detector, while
5%–17% of mergers have e10 Hz ≥ 0.3. On the other hand, if BS interactions are
confined to the AGN–disk plane due to torques from the disk, with 1–20 intermediate
binary states during each interaction, or if BHs can migrate to ≲ 10−3 pc from
the central supermassive BH, then 10%–70% of the mergers will be highly eccentric
(e10 Hz ≥ 0.3), consistent with the possible high eccentricity in GW190521.

text: Using high-resolution hydrodynamics simulations, we show that equal-mass binaries
accreting from a circumbinary disk evolve toward an orbital eccentricity of e
≃ 0.45, unless they are initialized on a nearly circular orbit with e ≲ 0.08,
in which case they further circularize. The implied bi-modal eccentricity distribution
resembles that seen in post-AGB stellar binaries. Large accretion spikes around
periapse impart a tell-tale, quasiperiodic, bursty signature on the light curves
of eccentric binaries. We predict that intermediate-mass and massive black hole
binaries at z ≲ 10 entering the LISA band will have measurable eccentricities
in the range of e ≃ 10−3 − 10−2, if they have experienced a gas-driven phase.
On the other hand, GW190521 would have entered the LIGO/Virgo band with undetectable
eccentricity ∼10−6 if it had been driven into the gravitational-wave regime by
a gas disk.

text: The science objectives of the LISA mission have been defined under the implicit
assumption of a 4-years continuous data stream. Based on the performance of LISA
Pathfinder, it is now expected that LISA will have a duty cycle of ≈0.75 , which
would reduce the effective span of usable data to 3 years. This paper reports
the results of a study by the LISA Science Group, which was charged with assessing
the additional science return of increasing the mission lifetime. We explore various
observational scenarios to assess the impact of mission duration on the main science
objectives of the mission. We find that the science investigations most affected
by mission duration concern the search for seed black holes at cosmic dawn, as
well as the study of stellar-origin black holes and of their formation channels
via multi-band and multi-messenger observations. We conclude that an extension
to 6 years of mission operations is recommended.

text: The successive discoveries of binary merger events by Advanced LIGO-Virgo
have been revealing the statistical properties of binary black hole (BBH) populations.
A stochastic gravitational wave background (GWB) is a useful tool to probe the
cosmological evolution of those compact mergers. In this paper, we study the upper
bound on a GWB produced by BBH mergers, whose stellar progenitors dominate the
reionization process at the cosmic dawn. Since early reionization by those progenitors
yields a high optical depth of the universe inconsistent with the {\it Planck}
measurements, the cumulative mass density is limited to ρ⋆≲107 M⊙ Mpc−3. Even
with this upper bound, the amplitude of a GWB owing to the high-z BBH mergers
is expected to be as high as Ωgw≃1.48+1.80−1.27×10−9 at f≃25 Hz, while their merger
rate at the present-day is consistent or lower than the observed GW event rate.
This level of GWB is detectable at the design sensitivity of Advanced LIGO-Virgo
and would indicate a major contribution of the high-z BBH population to the local
GW events. The spectral index is expected to be substantially flatter than the
canonical value of ≃2/3 generically produced by lower-redshift and less massive
BBHs. Moreover, if their mass function is more top-heavy than in the local universe,
the GWB spectrum is even more skewed toward lower frequencies, which would allow
us to extract information on the mass function of merging BBHs at high redshifts.

text: Convolutional Neural Networks (CNNs) are very popular in many fields including
computer vision, speech recognition, natural language processing, etc. Though
deep learning leads to groundbreaking performance in those domains, the networks
used are very computationally demanding and are far from being able to perform
in real-time applications even on a GPU, which is not power efficient and therefore
does not suit low power systems such as mobile devices. To overcome this challenge,
some solutions have been proposed for quantizing the weights and activations of
these networks, which accelerate the runtime significantly. Yet, this acceleration
comes at the cost of a larger error unless spatial adjustments are carried out.
The method proposed in this work trains quantized neural networks by noise injection
and a learned clamping, which improve accuracy. This leads to state-of-the-art
results on various regression and classification tasks, e.g., ImageNet classification
with architectures such as ResNet-18/34/50 with as low as 3 bit weights and activations.
We implement the proposed solution on an FPGA to demonstrate its applicability
for low-power real-time applications. The quantization code will become publicly
available upon acceptance.

text: 'Despite their great promise, artificial intelligence (AI) systems have yet
to become ubiquitous in the daily practice of medicine largely due to several
crucial unmet needs of healthcare practitioners. These include lack of explanations
in clinically meaningful terms, handling the presence of unknown medical conditions,
and transparency regarding the system’s limitations, both in terms of statistical
performance as well as recognizing situations for which the system’s predictions
are irrelevant. We articulate these unmet clinical needs as machine-learning (ML)
problems and systematically address them with cutting-edge ML techniques. We focus
on electrocardiogram (ECG) analysis as an example domain in which AI has great
potential and tackle two challenging tasks: the detection of a heterogeneous mix
of known and unknown arrhythmias from ECG and the identification of underlying
cardio-pathology from segments annotated as normal sinus rhythm recorded in patients
with an intermittent arrhythmia. We validate our methods by simulating a screening
for arrhythmias in a large-scale population while adhering to statistical significance
requirements. Specifically, our system 1) visualizes the relative importance of
each part of an ECG segment for the final model decision; 2) upholds specified
statistical constraints on its out-of-sample performance and provides uncertainty
estimation for its predictions; 3) handles inputs containing unknown rhythm types;
and 4) handles data from unseen patients while also flagging cases in which the
model’s outputs are not usable for a specific patient. This work represents a
significant step toward overcoming the limitations currently impeding the integration
of AI into clinical practice in cardiology and medicine in general.'

text: Fiber tractography is an important tool of computational neuroscience that
enables reconstructing the spatial connectivity and organization of white matter
of the brain. Fiber tractography takes advantage of diffusion Magnetic Resonance
Imaging (dMRI) which allows measuring the apparent diffusivity of cerebral water
along different spatial directions. Unfortunately, collecting such data comes
at the price of reduced spatial resolution and substantially elevated acquisition
times, which limits the clinical applicability of dMRI. This problem has been
thus far addressed using two principal strategies. Most of the efforts have been
extended towards improving the quality of signal estimation for any, yet fixed
sampling scheme (defined through the choice of diffusion-encoding gradients).
On the other hand, optimization over the sampling scheme has also proven to be
effective. Inspired by the previous results, the present work consolidates the
above strategies into a unified estimation framework, in which the optimization
is carried out with respect to both estimation model and sampling design concurrently.
The proposed solution offers substantial improvements in the quality of signal
estimation as well as the accuracy of ensuing analysis by means of fiber tractography.
While proving the optimality of the learned estimation models would probably need
more extensive evaluation, we nevertheless claim that the learned sampling schemes
can be of immediate use, offering a way to improve the dMRI analysis without the
necessity of deploying the neural network used for their estimation. We present
a comprehensive comparative analysis based on the Human Connectome Project data.

text: "What is the best way to match the nodes of two graphs? This graph alignment

shape-analysis concept of functional maps from the continuous to the discrete
case, and treat the graph alignment problem as a special case of the problem of
finding a mapping between functions on graphs. We present GRASP, a method that
captures multiscale structural characteristics from the eigenvectors of the graph’s
Laplacian and uses this information to align two graphs.Our experimental study,
featuring noise levels higher than anything used in previous studies, shows that
GRASP outperforms state-of-the-art methods for graph alignment across noise levels
and graph types."

text: We investigate a sheaf-theoretic interpretation of stratification learning
from geometric and topological perspectives. Our main result is the construction
of stratification learning algorithms framed in terms of a sheaf on a partially
ordered set with the Alexandroff topology. We prove that the resulting decomposition
is the unique minimal stratification for which the strata are homogeneous and
the given sheaf is constructible. In particular, when we choose to work with the
local homology sheaf, our algorithm gives an alternative to the local homology
transfer algorithm given in Bendich et al. (Proceedings of the 23rd Annual ACM-SIAM
Symposium on Discrete Algorithms, pp. 1355–1370, ACM, New York, 2012), and the
cohomology stratification algorithm given in Nanda (Found. Comput. Math. 20(2),
195–222, 2020). Additionally, we give examples of stratifications based on the
geometric techniques of Breiding et al. (Rev. Mat. Complut. 31(3), 545–593, 2018),
illustrating how the sheaf-theoretic approach can be used to study stratifications
from both topological and geometric perspectives. This approach also points toward
future applications of sheaf theory in the study of topological data analysis
by illustrating the utility of the language of sheaf theory in generalizing existing
algorithms.

text: Canonical parametrisations of classical confocal coordinate systems are introduced
and exploited to construct non-planar analogues of incircular (IC) nets on individual
quadrics and systems of confocal quadrics. Intimate connections with classical
deformations of quadrics that are isometric along asymptotic lines and circular
cross-sections of quadrics are revealed. The existence of octahedral webs of surfaces
of Blaschke type generated by asymptotic and characteristic lines that are diagonally
related to lines of curvature is proved theoretically and established constructively.
Appropriate samplings (grids) of these webs lead to three-dimensional extensions
of non-planar IC nets. Three-dimensional octahedral grids composed of planes and
spatially extending (checkerboard) IC-nets are shown to arise in connection with
systems of confocal quadrics in Minkowski space. In this context, the Laguerre
geometric notion of conical octahedral grids of planes is introduced. The latter
generalise the octahedral grids derived from systems of confocal quadrics in Minkowski
space. An explicit construction of conical octahedral grids is presented. The
results are accompanied by various illustrations which are based on the explicit
formulae provided by the theory.

text: P-glycoprotein (ABCB1) and breast cancer resistance protein (ABCG2) restrict
at the blood–brain barrier (BBB) the brain distribution of the majority of currently
known molecularly targeted anticancer drugs. To improve brain delivery of dual
ABCB1/ABCG2 substrates, both ABCB1 and ABCG2 need to be inhibited simultaneously
at the BBB. We examined the feasibility of simultaneous ABCB1/ABCG2 inhibition
with i.v. co-infusion of erlotinib and tariquidar by studying brain distribution
of the model ABCB1/ABCG2 substrate [11C]erlotinib in mice and rhesus macaques
with PET. Tolerability of the erlotinib/tariquidar combination was assessed in
human embryonic stem cell-derived cerebral organoids. In mice and macaques, baseline
brain distribution of [11C]erlotinib was low (brain distribution volume, VT,brain < 0.3 mL/cm3).
Co-infusion of erlotinib and tariquidar increased VT,brain in mice by 3.0-fold
and in macaques by 3.4- to 5.0-fold, while infusion of erlotinib alone or tariquidar
alone led to less pronounced VT,brain increases in both species. Treatment of
cerebral organoids with erlotinib/tariquidar led to an induction of Caspase-3-dependent
apoptosis. Co-infusion of erlotinib/tariquidar may potentially allow for complete
ABCB1/ABCG2 inhibition at the BBB, while simultaneously achieving brain-targeted
EGFR inhibition. Our protocol may be applicable to enhance brain delivery of molecularly
targeted anticancer drugs for a more effective treatment of brain tumors.

text: Plants are able to orient their growth according to gravity, which ultimately
controls both shoot and root architecture.1 Gravitropism is a dynamic process
whereby gravistimulation induces the asymmetric distribution of the plant hormone
auxin, leading to asymmetric growth, organ bending, and subsequent reset of auxin
distribution back to the original pre-gravistimulation situation.1, 2, 3 Differential
auxin accumulation during the gravitropic response depends on the activity of
polarly localized PIN-FORMED (PIN) auxin-efflux carriers.1, 2, 3, 4 In particular,
the timing of this dynamic response is regulated by PIN2,5,6 but the underlying
molecular mechanisms are poorly understood. Here, we show that MEMBRANE ASSOCIATED
KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response.
We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by
acting as a negative regulator of the cell-surface signaling mediated by the receptor-like
kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that
the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself,
which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our
findings suggest that the timing of the root gravitropic response is orchestrated
by the reversible inhibition of the TMK1 signaling pathway at the cell surface.

text: "We study properties of the volume of projections of the n-dimensional\r\ncross-polytope
$\\crosp^n = \\{ x \\in \\R^n \\mid |x_1| + \\dots + |x_n| \\leqslant 1\\}.$ We
prove that the projection of $\\crosp^n$ onto a k-dimensional coordinate subspace
has the maximum possible volume for k=2 and for k=3.\r\nWe obtain the exact lower
bound on the volume of such a projection onto a two-dimensional plane. Also, we
show that there exist local maxima which are not global ones for the volume of
a projection of $\\crosp^n$ onto a k-dimensional subspace for any n>k⩾2."

text: Cesium lead halides have intrinsically unstable crystal lattices and easily
transform within perovskite and nonperovskite structures. In this work, we explore
the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS
at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6
nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into
the PbS lattice with a consequent increase in the concentration of free charge
carriers. This new doping strategy enables the adjustment of the density of charge
carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for
doping other nanocrystal-based semiconductors.
