Antichiral states in 2D\nsemimetals, i.e., copropagating edge modes on opposite edges compensated by a\ncounterpropagating bulk current, are also predicted, but, to date, no\nrealization of such states in a solid-state system has been found.

+content = "Anomalous electric currents along a magnetic field, first predicted to emerge\nduring large heavy ion collision experiments, were also observed a few years\nago in condensed matter environments, exploring the fact that charge carriers\nin Dirac/Weyl semi-metals exhibit a relativistic-like behavior. The mechanism\nthrough which such currents are generated relies on an imbalance in the\nchirality of systems immersed in a magnetic background, leading to the\nso-called chiral magnetic effect (CME). While chiral magnetic currents have\nbeen observed in materials in three space dimensions, in this work we propose\nthat an analog of the chiral magnetic effect can be constructed in two space\ndimensions, corresponding to a novel type of intrinsic half-integer Quantum\nHall effect, thereby also offering a topological protection mechanism for the\ncurrent. While the 3D chiral anomaly underpins the CME, its 2D cousin is\nemerging from the 2D parity anomaly, we thence call it the parity magnetic\neffect (PME). It can occur in disturbed honeycomb lattices where both spin\ndegeneracy and time reversal symmetry are broken. These configurations harbor\ntwo distinct gap-opening mechanisms that, when occurring simultaneously, drive\nslightly different gaps in each valley, establishing an analog of the necessary\nchiral imbalance. Some examples of promising material setups that fulfill the\nprerequisites of our proposal are also listed."

+content = "This paper presents a model-free reinforcement learning (RL) algorithm to\nsynthesize a control policy that maximizes the satisfaction probability of\nlinear temporal logic (LTL) specifications. Due to the consideration of\nenvironment and motion uncertainties, we model the robot motion as a\nprobabilistic labeled Markov decision process with unknown transition\nprobabilities and unknown probabilistic label functions. The LTL task\nspecification is converted to a limit deterministic generalized B\\\"uchi\nautomaton (LDGBA) with several accepting sets to maintain dense rewards during\nlearning. The novelty of applying LDGBA is to construct an embedded LDGBA\n(E-LDGBA) by designing a synchronous tracking-frontier function, which enables\nthe record of non-visited accepting sets without increasing dimensional and\ncomputational complexity. With appropriate dependent reward and discount\nfunctions, rigorous analysis shows that any method that optimizes the expected\ndiscount return of the RL-based approach is guaranteed to find the optimal\npolicy that maximizes the satisfaction probability of the LTL specifications. A\nmodel-free RL-based motion planning strategy is developed to generate the\noptimal policy in this paper. The effectiveness of the RL-based control\nsynthesis is demonstrated via simulation and experimental results."

+content = "Beamforming is an imaging tool for the investigation of aeroacoustic\nphenomena and results in high dimensional data that is broken down to spectra\nby integrating spatial Regions Of Interest. This paper presents two methods\nthat enable the automated identification of aeroacoustic sources in sparse\nbeamforming maps and the extraction of their corresponding spectra to overcome\nthe manual definition of Regions Of Interest. The methods are evaluated on two\nscaled airframe half-model wind-tunnel measurements and on a generic monopole\nsource. The first relies on the spatial normal distribution of aeroacoustic\nbroadband sources in sparse beamforming maps. The second uses hierarchical\nclustering methods. Both methods are robust to statistical noise and predict\nthe existence, location, and spatial probability estimation for sources based\non which Regions Of Interest are automatically determined."

It is known that complementarity relations for wave-particle duality are\nsaturated only for pure, single-quanton, quantum states. For mixed states, the\nwave-particle quantifiers never saturate a complementarity relation and can\neven reach zero for a maximally mixed state. To fully characterize a quanton,\nit is not enough to consider its wave-particle aspect; we have also to regard\nits quantum correlations with other systems.

The code-reuse approach allows one to exploit\nvulnerabilities in the presence of operating system protection that prohibits\ndata memory execution. This paper contains a description of various code-reuse\nmethods: return-to-libc attack, return-oriented programming, jump-oriented\nprogramming, and others. We define fundamental terms: gadget, gadget frame,\ngadget catalog. Moreover, we show that, in fact, a gadget is an instruction,\nand a set of gadgets defines a virtual machine. We can reduce an exploit\ncreation problem to code generation for this virtual machine. Each particular\nexecutable file defines a virtual machine instruction set. We provide a survey\nof methods for gadgets searching and determining their semantics (creating a\ngadget catalog). These methods allow one to get the virtual machine instruction\nset. If a set of gadgets is Turing-complete, then a compiler can use a gadget\ncatalog as a target architecture. However, some instructions can be absent.\nHence we discuss several approaches to replace missing instructions with\nmultiple gadgets. An exploit generation tool can chain gadgets by pattern\nsearching (regular expressions) or considering gadgets semantics. Furthermore,\nsome chaining methods use genetic algorithms, while others use SMT-solvers. We\ncompare existing open-source tools and propose a testing system rop-benchmark\nthat can be used to verify whether a generated chain successfully opens a\nshell."

+content = "Conventional frequentist learning, as assumed by existing federated learning\nprotocols, is limited in its ability to quantify uncertainty, incorporate prior\nknowledge, guide active learning, and enable continual learning. Bayesian\nlearning provides a principled approach to address all these limitations, at\nthe cost of an increase in computational complexity. This paper studies\ndistributed Bayesian learning in a wireless data center setting encompassing a\ncentral server and multiple distributed workers. Prior work on wireless\ndistributed learning has focused exclusively on frequentist learning, and has\nintroduced the idea of leveraging uncoded transmission to enable \"over-the-air\"\ncomputing. Unlike frequentist learning, Bayesian learning aims at evaluating\napproximations or samples from a global posterior distribution in the model\nparameter space. This work investigates for the first time the design of\ndistributed one-shot, or \"embarrassingly parallel\", Bayesian learning protocols\nin wireless data centers via consensus Monte Carlo (CMC). Uncoded transmission\nis introduced not only as a way to implement \"over-the-air\" computing, but also\nas a mechanism to deploy channel-driven MC sampling: Rather than treating\nchannel noise as a nuisance to be mitigated, channel-driven sampling utilizes\nchannel noise as an integral part of the MC sampling process. A simple wireless\nCMC scheme is first proposed that is asymptotically optimal under Gaussian\nlocal posteriors. Then, for arbitrary local posteriors, a variational\noptimization strategy is introduced. Simulation results demonstrate that, if\nproperly accounted for, channel noise can indeed contribute to MC sampling and\ndoes not necessarily decrease the accuracy level."

+content = "Several works have demonstrated the use of variational autoencoders (VAEs)\nfor generating levels in the style of existing games and blending levels across\ndifferent games. Further, quality-diversity (QD) algorithms have also become\npopular for generating varied game content by using evolution to explore a\nsearch space while focusing on both variety and quality. To reap the benefits\nof both these approaches, we present a level generation and game blending\napproach that combines the use of VAEs and QD algorithms. Specifically, we\ntrain VAEs on game levels and run the MAP-Elites QD algorithm using the learned\nlatent space of the VAE as the search space. The latent space captures the\nproperties of the games whose levels we want to generate and blend, while\nMAP-Elites searches this latent space to find a diverse set of levels\noptimizing a given objective such as playability. We test our method using\nmodels for 5 different platformer games as well as a blended domain spanning 3\nof these games. We refer to using MAP-Elites for blending as Blend-Elites. Our\nresults show that MAP-Elites in conjunction with VAEs enables the generation of\na diverse set of playable levels not just for each individual game but also for\nthe blended domain while illuminating game-specific regions of the blended\nlatent space."

For\nefficiently processing these computational- and memory-intensive applications,\ntensors of these over-parameterized models are compressed by leveraging\nsparsity, size reduction, and quantization of tensors.

+content = "Despite great progress in 3D human pose estimation from videos, it is still\nan open problem to take full advantage of redundant 2D pose sequences to learn\nrepresentative representation for generating one single 3D pose. To this end,\nwe propose an improved Transformer-based architecture, called Strided\nTransformer, for 3D human pose estimation in videos to lift a sequence of 2D\njoint locations to a 3D pose. Specifically, a vanilla Transformer encoder (VTE)\nis adopted to model long-range dependencies of 2D pose sequences. To reduce\nredundancy of the sequence and aggregate information from local context,\nstrided convolutions are incorporated into VTE to progressively reduce the\nsequence length. The modified VTE is termed as strided Transformer encoder\n(STE) which is built upon the outputs of VTE. STE not only effectively\naggregates long-range information to a single-vector representation in a\nhierarchical global and local fashion but also significantly reduces the\ncomputation cost. Furthermore, a full-to-single supervision scheme is designed\nat both the full sequence scale and single target frame scale, applied to the\noutputs of VTE and STE, respectively. This scheme imposes extra temporal\nsmoothness constraints in conjunction with the single target frame supervision\nand improves the representation ability of features for the target frame. The\nproposed architecture is evaluated on two challenging benchmark datasets,\nHuman3.6M and HumanEva-I, and achieves state-of-the-art results with much fewer\nparameters."

In this paper, we\ndescribe an eXplanatory Artificial Intelligence (XAI) that reaches the same\nlevel of performance as black-box AI, for the task of classifying Diabetic\nRetinopathy (DR) severity using Color Fundus Photography (CFP). This algorithm,\ncalled ExplAIn, learns to segment and categorize lesions in images; the final\nimage-level classification directly derives from these multivariate lesion\nsegmentations. The novelty of this explanatory framework is that it is trained\nfrom end to end, with image supervision only, just like black-box AI\nalgorithms: the concepts of lesions and lesion categories emerge by themselves.\nFor improved lesion localization, foreground/background separation is trained\nthrough self-supervision, in such a way that occluding foreground pixels\ntransforms the input image into a healthy-looking image. The advantage of such\nan architecture is that automatic diagnoses can be explained simply by an image\nand/or a few sentences. ExplAIn is evaluated at the image level and at the\npixel level on various CFP image datasets. We expect this new framework, which\njointly offers high classification performance and explainability, to\nfacilitate AI deployment."

+content = "Vessel segmentation is an essential task in many clinical applications.\nAlthough supervised methods have achieved state-of-art performance, acquiring\nexpert annotation is laborious and mostly limited for two-dimensional datasets\nwith a small sample size. On the contrary, unsupervised methods rely on\nhandcrafted features to detect tube-like structures such as vessels. However,\nthose methods require complex pipelines involving several hyper-parameters and\ndesign choices rendering the procedure sensitive, dataset-specific, and not\ngeneralizable. We propose a self-supervised method with a limited number of\nhyper-parameters that is generalizable across modalities. Our method uses\ntube-like structure properties, such as connectivity, profile consistency, and\nbifurcation, to introduce inductive bias into a learning algorithm. To model\nthose properties, we generate a vector field that we refer to as a flow. Our\nexperiments on various public datasets in 2D and 3D show that our method\nperforms better than unsupervised methods while learning useful transferable\nfeatures from unlabeled data. Unlike generic self-supervised methods, the\nlearned features learn vessel-relevant features that are transferable for\nsupervised approaches, which is essential when the number of annotated data is\nlimited."

The proposed computational\nprocedure, HIgh-dimensional fast ConvolU-tional framework (HICU), provides\nfast, memory-efficient recovery of unsampled k-space points. For demonstration,\nHICU is applied to six 2D T2-weighted brain, seven 2D cardiac cine, five 3D\nknee, and one multi-shot diffusion weighted imaging (MSDWI) datasets.\n  Results: The 2D imaging results show that HICU can offer one to two orders of\nmagnitude computation speedup compared to other Cl-MRI methods without\nsacrificing imaging quality. The 2D cine and 3D imaging results show that the\ncomputational acceleration techniques included in HICU yield computing time on\npar with SENSE-based compressed sensing methods with up to 3 dB improvement in\nsignal-to-error ratio and better perceptual quality. The MSDWI results\ndemonstrate the feasibility of HICU for a challenging multi-shot echo-planar\nimaging application.\n  Conclusions: The presented method, HICU, offers efficient computation and\nscalability as well as extendibility to a wide variety of MRI applications."

+content = "(Gradient) Expectation Maximization (EM) is a widely used algorithm for\nestimating the maximum likelihood of mixture models or incomplete data\nproblems. A major challenge facing this popular technique is how to effectively\npreserve the privacy of sensitive data. Previous research on this problem has\nalready lead to the discovery of some Differentially Private (DP) algorithms\nfor (Gradient) EM. However, unlike in the non-private case, existing techniques\nare not yet able to provide finite sample statistical guarantees. To address\nthis issue, we propose in this paper the first DP version of (Gradient) EM\nalgorithm with statistical guarantees. Moreover, we apply our general framework\nto three canonical models: Gaussian Mixture Model (GMM), Mixture of Regressions\nModel (MRM) and Linear Regression with Missing Covariates (RMC). Specifically,\nfor GMM in the DP model, our estimation error is near optimal in some cases.\nFor the other two models, we provide the first finite sample statistical\nguarantees. Our theory is supported by thorough numerical experiments."

SMEs have specific\ncharacteristics which separate them from large companies and influence their\nadoption of good cybersecurity practices. To mitigate the SMEs' cybersecurity\nadoption issues and raise their awareness of cyber threats, we have designed a\nself-paced security assessment and capability improvement method, CYSEC. CYSEC\nis a security awareness and training method that utilises self-reporting\nquestionnaires to collect companies' information about cybersecurity awareness,\npractices, and vulnerabilities to generate automated recommendations for\ncounselling. However, confidentiality concerns about cybersecurity information\nhave an impact on companies' willingness to share their information. Security\ninformation sharing decreases the risk of incidents and increases users'\nself-efficacy in security awareness programs. This paper presents the results\nof semi-structured interviews with seven chief information security officers of\nSMEs to evaluate the impact of online consent communication on motivation for\ninformation sharing. The results were analysed in respect of the Self\nDetermination Theory. The findings demonstrate that online consent with\nmultiple options for indicating a suitable level of agreement improved\nmotivation for information sharing. This allows many SMEs to participate in\nsecurity information sharing activities and supports security experts to have a\nbetter overview of common vulnerabilities.

+content = "This paper studies the nature of fractional linear transformations in a\ngeneral relativity context as well as in a quantum theoretical framework. Two\nfeatures are found to deserve special attention: the first is the possibility\nof separating the limit-point condition at infinity into loxodromic,\nhyperbolic, parabolic and elliptic cases. This is useful in a context in which\none wants to look for a correspondence between essentially self-adjoint\nspherically symmetric Hamiltonians of quantum physics and the theory of\nBondi-Metzner-Sachs transformations in general relativity. The analogy\ntherefore arising, suggests that further investigations might be performed for\na theory in which the role of fractional linear maps is viewed as a bridge\nbetween the quantum theory and general relativity. The second aspect to point\nout is the possibility of interpreting the limit-point condition at both ends\nof the positive real line, for a second-order singular differential operator,\nwhich occurs frequently in applied quantum mechanics, as the limiting procedure\narising from a very particular Kleinian group which is the hyperbolic cyclic\ngroup. In this framework, this work finds that a consistent system of equations\ncan be derived and studied. Hence one is led to consider the entire\ntranscendental functions, from which it is possible to construct a fundamental\nsystem of solutions of a second-order differential equation with singular\nbehavior at both ends of the positive real line, which in turn satisfy the\nlimit-point conditions."

+content = "Video moment retrieval targets at retrieving a moment in a video for a given\nlanguage query. The challenges of this task include 1) the requirement of\nlocalizing the relevant moment in an untrimmed video, and 2) bridging the\nsemantic gap between textual query and video contents. To tackle those\nproblems, early approaches adopt the sliding window or uniform sampling to\ncollect video clips first and then match each clip with the query. Obviously,\nthese strategies are time-consuming and often lead to unsatisfied accuracy in\nlocalization due to the unpredictable length of the golden moment. To avoid the\nlimitations, researchers recently attempt to directly predict the relevant\nmoment boundaries without the requirement to generate video clips first. One\nmainstream approach is to generate a multimodal feature vector for the target\nquery and video frames (e.g., concatenation) and then use a regression approach\nupon the multimodal feature vector for boundary detection. Although some\nprogress has been achieved by this approach, we argue that those methods have\nnot well captured the cross-modal interactions between the query and video\nframes.\n  In this paper, we propose an Attentive Cross-modal Relevance Matching (ACRM)\nmodel which predicts the temporal boundaries based on an interaction modeling.\nIn addition, an attention module is introduced to assign higher weights to\nquery words with richer semantic cues, which are considered to be more\nimportant for finding relevant video contents. Another contribution is that we\npropose an additional predictor to utilize the internal frames in the model\ntraining to improve the localization accuracy. Extensive experiments on two\ndatasets TACoS and Charades-STA demonstrate the superiority of our method over\nseveral state-of-the-art methods. Ablation studies have been also conducted to\nexamine the effectiveness of different modules in our ACRM model."

Such risk\nscore models contain numerous parameters that must be set by the public health\nauthority. In this paper, we show how to automatically learn these parameters\nfrom data.\n  Our method needs access to exposure and outcome data. Although this data is\nalready being collected (in an aggregated, privacy-preserving way) by several\nhealth authorities, in this paper we limit ourselves to simulated data, so that\nwe can systematically study the different factors that affect the feasibility\nof the approach. In particular, we show that the parameters become harder to\nestimate when there is more missing data (e.g., due to infections which were\nnot recorded by the app), and when there is model misspecification.\nNevertheless, the learning approach outperforms a strong manually designed\nbaseline. Furthermore, the learning approach can adapt even when the risk\nfactors of the disease change, e.g., due to the evolution of new variants, or\nthe adoption of vaccines."

A meaningful set of states that can be efficiently prepared\nin experiments are ground states of gapped local Hamiltonians, which are well\napproximated by matrix product states. In this work, we introduce a picture of\ngeneric states within the trivial phase of matter with respect to their\nnon-equilibrium and entropic properties: We do so by rigorously exploring\nnon-translation-invariant matrix product states drawn from a local i.i.d.\nHaar-measure. We arrive at these results by exploiting techniques for computing\nmoments of random unitary matrices and by exploiting a mapping to partition\nfunctions of classical statistical models, a method that has lead to valuable\ninsights on local random quantum circuits. Specifically, we prove that such\ndisordered random matrix product states equilibrate exponentially well with\noverwhelming probability under the time evolution of Hamiltonians featuring a\nnon-degenerate spectrum. Moreover, we prove two results about the entanglement\nRenyi entropy: The entropy with respect to sufficiently disconnected subsystems\nis generically extensive in the system-size, and for small connected systems\nthe entropy is almost maximal for sufficiently large bond dimensions."

Two strong events were observed as transients\nresponding to energy deposition within acoustic modes of the cavity. The first\nevent occurred during Run 1 on the 12/05/2019 (UTC), and was observed in the\n5.506 MHz mode, while the second mode at 8.392 MHz observed no event. During\nRun 2, a second event occurred on the 27/11/2019(UTC) and was observed by both\nmodes.
