+content = "Semantic parsing is the task of converting natural language utterances to\nmachine-understandable meaning representations, such as logic forms or\nprogramming languages. Training datasets for semantic parsing are typically\nsmall due to the higher expertise required for annotation than most other NLP\ntasks. As a result, models for this application usually require additional\nprior knowledge to be built into the architecture or algorithm. The increased\ndependency on human experts hinders automation and raises the development and\nmaintenance costs in practice. This work investigates whether a generic\ntransformer-based seq2seq model can achieve competitive performance with\nminimal semantic-parsing specific inductive bias design. By exploiting a\nrelatively large monolingual corpus of the target programming language, which\nis cheap to mine from the web, unlike a parallel corpus, we achieved 80.75%\nexact match accuracy on Django and 32.57 BLEU score on CoNaLa, both are SOTA to\nthe best of our knowledge. This positive evidence highlights a potentially\neasier path toward building accurate semantic parsers in the wild."

+content = "Threshold schemes exist for many cryptographic primitives like signatures,\nkey derivation functions, and ciphers. At the same time, practical key exchange\nprotocols based on Diffie-Hellman (DH) or ECDSA primitives are not designed or\nimplemented in a threshold setting. In this paper, we implement popular key\nexchange protocols in a threshold manner and show that this approach can be\nused in practice. First, we introduce two basic threshold DH key agreement\nschemes that provide enhanced security features in comparison with the classic\nDH primitive: dealerless distributed key generation, threshold shared key\ncomputation, and private key shares refreshing. We implemented the proposed DH\nschemes within WireGuard protocol to demonstrate its effectiveness, efficiency,\nand usability in practice. The open question is the security of the proposed\nschemes and their instantiation from the elliptic curves used in key agreement\nprotocols: NIST curves, Russian GOST curves, and Curve25519. Second, we propose\nan idea of implementing TLS in a threshold setting that can be used instead of\nKeyless SSL/TLS technology, and provide the measurements of TLS key exchanges\nbased on threshold ECDSA. Even if we don't provide any formal definitions,\nsecurity analysis, and mathematical proofs, we believe that the ideas and\nmechanisms suggested in this paper can be interesting and useful. The main\nintention of the paper is to start discussions and raise awareness of the\nchallenges and problems arising when moving to threshold key exchange\nprotocols."

+content = "Context: Code smells are considered symptoms of poor design, leading to\nfuture problems, such as reduced maintainability. Except for anecdotal cases\n(e. g. code dropout), a code smell survives until it gets explicitly refactored\nor removed. This paper presents a longitudinal study on the survival of code\nsmells for web apps built with PHP.\n  Objectives: RQ: (i) code smells survival depends on their scope? (ii)\npractitioners attitudes towards code smells removal in web apps have changed\nthroughout time? (iii) how long code smells survive in web applications? (iv)\nare there sudden variations (anomalies) in the density of code smells through\nthe evolution of web apps?\n  Method: We analyze the evolution of 6 code smells in 8 web applications\nwritten in PHP at the server side, across several years, using the survival\nanalysis technique. We classify code smells according to scope in two\ncategories: scattered and localized. Scattered code smells are expected to be\nmore harmful since their influence is not circumscribed as in localized code\nsmells. We split the observations for each web app into two equal and\nconsecutive timeframes, to test the hypothesis that code smells awareness has\nincreased throughout time. As for the anomalies, we standardize their detection\ncriteria.\n  Results: We present some evidence that code smells survival depends on their\nscope: the average survival rate decreases in some of them, while the opposite\nis observed for the remainder. The survival of localized code smells is around\n4 years, while the scattered ones live around 5 years. Around 60% of the smells\nare removed, and some live through all the application life. We also show how a\ngraphical representation of anomalies found in the evolution of code smells\nallows unveiling the story of a development project and make managers aware of\nthe need for enforcing regular refactoring practices."

+content = "The low-rank stochastic semidefinite optimization has attracted rising\nattention due to its wide range of applications. The nonconvex reformulation\nbased on the low-rank factorization, significantly improves the computational\nefficiency but brings some new challenge to the analysis. The stochastic\nvariance reduced gradient (SVRG) method has been regarded as one of the most\neffective methods. SVRG in general consists of two loops, where a reference\nfull gradient is first evaluated in the outer loop and then used to yield a\nvariance reduced estimate of the current gradient in the inner loop. Two\noptions have been suggested to yield the output of the inner loop, where Option\nI sets the output as its last iterate, and Option II yields the output via\nrandom sampling from all the iterates in the inner loop. However, there is a\nsignificant gap between the theory and practice of SVRG when adapted to the\nstochastic semidefinite programming (SDP). SVRG practically works better with\nOption I, while most of existing theoretical results focus on Option II. In\nthis paper, we fill this gap via exploiting a new semi-stochastic variant of\nthe original SVRG with Option I adapted to the semidefinite optimization.\nEquipped with this, we establish the global linear submanifold convergence\n(i.e., converging exponentially fast to a submanifold of a global minimum under\nthe orthogonal group action) of the proposed SVRG method, given a provable\ninitialization scheme and under certain smoothness and restricted strongly\nconvex assumptions. Our analysis includes the effects of the mini-batch size\nand update frequency in the inner loop as well as two practical step size\nstrategies, the fixed and stabilized Barzilai-Borwein step sizes. Some\nnumerical results in matrix sensing demonstrate the efficiency of proposed SVRG\nmethod outperforming Option II counterpart as well as others."

By using a\n3+1 neutrino flavor oscillation model, we study how such a type of dark matter\nimprints the solar neutrino fluxes, spectra, and survival probabilities of\nelectron neutrinos. The current solar neutrino measurements allow us to define\nan upper limit for the ratio of the mass of a light dark matter particle\nm_ϕ and the Fermi constant G_ϕ, such that G_ϕ/m_ϕ must be\nsmaller than 10^30  G_ F  eV^-1 to be in agreement with current\nsolar neutrino data from the Borexino, Sudbury Neutrino Observatory, and\nSuper-Kamiokande detectors. Moreover, for models with a very small Fermi\nconstant, the amplitude of the time variability must be lower than 3% to be\nconsistent with current solar neutrino data. We also found that solar neutrino\ndetectors like Darwin, able to measure neutrino fluxes in the low energy-range\nwith high accuracy, will provide additional constraints to this class of models\nthat complement the ones obtained from the current solar neutrino detectors."

Here, we explore the\npossibility that the dark matter in the current universe is made of two\nparticles, a sterile neutrino and a very light dark matter particle. By using a\n3+1 neutrino flavor oscillation model, we study how such a type of dark matter\nimprints the solar neutrino fluxes, spectra, and survival probabilities of\nelectron neutrinos. The current solar neutrino measurements allow us to define\nan upper limit for the ratio of the mass of a light dark matter particle\n$m_\\phi$ and the Fermi constant $G_\\phi$, such that $G_\\phi/m_\\phi $ must be\nsmaller than $10^{30}\\; G_{\\rm F}\\; eV^{-1}$ to be in agreement with current\nsolar neutrino data from the Borexino, Sudbury Neutrino Observatory, and\nSuper-Kamiokande detectors. Moreover, for models with a very small Fermi\nconstant, the amplitude of the time variability must be lower than $3\\%$ to be\nconsistent with current solar neutrino data. We also found that solar neutrino\ndetectors like Darwin, able to measure neutrino fluxes in the low energy-range\nwith high accuracy, will provide additional constraints to this class of models\nthat complement the ones obtained from the current solar neutrino detectors."

+content = "Understanding the dynamics of charge exchange between a solid surface and a\nliquid is fundamental to various situations, ranging from nanofiltration to\ncatalysis and electrochemistry. Charge transfer is ultimately determined by\nphysicochemical processes (surface group dissociation, ion adsorption, etc...)\noccurring in the few layers of molecules at the interface between the solid and\nthe liquid. Unfortunately, these processes remain largely uncharted due to the\nexperimental challenges in probing interfacial charge dynamics with\nsufficiently high spatial and temporal resolution. Here, we resolve at the\nsingle-charge scale, the dynamics of proton charges at the interface between an\nhBN crystal and binary mixtures of water and organic amphiphilic solvents (e.g.\nalcohol), evidencing a dramatic influence of solvation on interfacial dynamics.\nOur observations rely on the application of spectral Single Molecule\nLocalization Microscopy (sSMLM) to two types of optically active defects at the\nhBN surface, which act as intrinsic optical markers for both surface\nprotonation and interaction with apolar alkyl groups of the organic solvent. We\nuse sSMLM to reveal interfacial proton charge transport as a succession of\njumps between the titratable surface defects, mediated by the transport of the\nsolvated proton charge along the solid/liquid interface. By changing the\nrelative concentration of water in binary mixtures, we evidence a non-trivial\neffect on interfacial proton charge dynamics, leading at intermediate water\nconcentration to an increased affinity of the proton charge to the solid\nsurface, accompanied by an increased surface diffusivity. These measurements\nconfirm the strong role of solvation on interfacial proton charge transport and\nestablish the potential of single-molecule localization techniques to probe a\nwide range of dynamic processes at solid/liquid interfaces."

+content = "Federated learning (FL) can empower Internet-of-Vehicles (IoV) networks by\nleveraging smart vehicles (SVs) to participate in the learning process with\nminimum data exchanges and privacy disclosure. The collected data and learned\nknowledge can help the vehicular service provider (VSP) improve the global\nmodel accuracy, e.g., for road safety as well as better profits for both VSP\nand participating SVs. Nonetheless, there exist major challenges when\nimplementing the FL in IoV networks, such as dynamic activities and diverse\nquality-of-information (QoI) from a large number of SVs, VSP's limited payment\nbudget, and profit competition among SVs. In this paper, we propose a novel\ndynamic FL-based economic framework for an IoV network to address these\nchallenges. Specifically, the VSP first implements an SV selection method to\ndetermine a set of the best SVs for the FL process according to the\nsignificance of their current locations and information history at each\nlearning round. Then, each selected SV can collect on-road information and\noffer a payment contract to the VSP based on its collected QoI. For that, we\ndevelop a multi-principal one-agent contract-based policy to maximize the\nprofits of the VSP and learning SVs under the VSP's limited payment budget and\nasymmetric information between the VSP and SVs. Through experimental results\nusing real-world on-road datasets, we show that our framework can converge 57%\nfaster (even with only 10% of active SVs in the network) and obtain much higher\nsocial welfare of the network (up to 27.2 times) compared with those of other\nbaseline FL methods."

Various technological challenges must be overcome\nto achieve our goal. Among many potential technologies, reconfigurable\nintelligent surface (RIS) and artificial intelligence (AI) have attracted\nextensive attention, thereby leading to a proliferation of studies for\nutilizing them in wireless communication systems. The RIS-based wireless\ncommunication frameworks and AI-enabled technologies, two of the promising\ntechnologies for the sixth-generation networks, interact and promote with each\nother, striving to collaboratively create a controllable, intelligent,\nreconfigurable, and programmable wireless propagation environment. This paper\nexplores the road to implementing the combination of RIS and AI; specifically,\nintegrating AI-enabled technologies into RIS-based frameworks for maximizing\nthe practicality of RIS to facilitate the realization of smart radio\npropagation environments, elaborated from shallow to deep insights. We begin\nwith the basic concept and fundamental characteristics of RIS, followed by the\noverview of the research status of RIS. Then, we analyze the inevitable trend\nof RIS to be combined with AI. In particular, we focus on recent research about\nRIS-based architectures embedded with AI, elucidating from the intelligent\nstructures and systems of metamaterials to the AI-embedded RIS-assisted\nwireless communication systems.

+content = "BERT, as one of the pretrianed language models, attracts the most attention\nin recent years for creating new benchmarks across GLUE tasks via fine-tuning.\nOne pressing issue is to open up the blackbox and explain the decision makings\nof BERT. A number of attribution techniques have been proposed to explain BERT\nmodels, but are often limited to sequence to sequence tasks. In this paper, we\nadapt existing attribution methods on explaining decision makings of BERT in\nsequence classification tasks. We conduct extensive analyses of four existing\nattribution methods by applying them to four different datasets in sentiment\nanalysis. We compare the reliability and robustness of each method via various\nablation studies. Furthermore, we test whether attribution methods explain\ngeneralized semantics across semantically similar tasks. Our work provides\nsolid guidance for using attribution methods to explain decision makings of\nBERT for downstream classification tasks."

+content = "Adaptive learning rate methods have been successfully applied in many fields,\nespecially in training deep neural networks. Recent results have shown that\nadaptive methods with exponential increasing weights on squared past gradients\n(i.e., ADAM, RMSPROP) may fail to converge to the optimal solution. Though many\nalgorithms, such as AMSGRAD and ADAMNC, have been proposed to fix the\nnon-convergence issues, achieving a data-dependent regret bound similar to or\nbetter than ADAGRAD is still a challenge to these methods. In this paper, we\npropose a novel adaptive method weighted adaptive algorithm (WADA) to tackle\nthe non-convergence issues. Unlike AMSGRAD and ADAMNC, we consider using a\nmilder growing weighting strategy on squared past gradient, in which weights\ngrow linearly. Based on this idea, we propose weighted adaptive gradient method\nframework (WAGMF) and implement WADA algorithm on this framework. Moreover, we\nprove that WADA can achieve a weighted data-dependent regret bound, which could\nbe better than the original regret bound of ADAGRAD when the gradients decrease\nrapidly. This bound may partially explain the good performance of ADAM in\npractice. Finally, extensive experiments demonstrate the effectiveness of WADA\nand its variants in comparison with several variants of ADAM on training convex\nproblems and deep neural networks."

+content = "This paper investigates the cooperative planning and control problem for\nmultiple connected autonomous vehicles (CAVs) in different scenarios. In the\nexisting literature, most of the methods suffer from significant problems in\ncomputational efficiency. Besides, as the optimization problem is nonlinear and\nnonconvex, it typically poses great difficultly in determining the optimal\nsolution. To address this issue, this work proposes a novel and completely\nparallel computation framework by leveraging the alternating direction method\nof multipliers (ADMM). The nonlinear and nonconvex optimization problem in the\nautonomous driving problem can be divided into two manageable subproblems; and\nthe resulting subproblems can be solved by using effective optimization methods\nin a parallel framework. Here, the differential dynamic programming (DDP)\nalgorithm is capable of addressing the nonlinearity of the system dynamics\nrather effectively; and the nonconvex coupling constraints with small\ndimensions can be approximated by invoking the notion of semi-definite\nrelaxation (SDR), which can also be solved in a very short time. Due to the\nparallel computation and efficient relaxation of nonconvex constraints, our\nproposed approach effectively realizes real-time implementation and thus also\nextra assurance of driving safety is provided. In addition, two transportation\nscenarios for multiple CAVs are used to illustrate the effectiveness and\nefficiency of the proposed method."

+content = "The growth of surface plasmonic microbubbles in binary water/ethanol\nsolutions is experimentally studied. The microbubbles are generated by\nilluminating a gold nanoparticle array with a continuous wave laser. Plasmonic\nbubbles exhibit ethanol concentration-dependent behaviors. For low ethanol\nconcentrations (f_e) of < 67.5%, bubbles do not exist at the solid-liquid\ninterface. For high f_e values of >80%, the bubbles behave as in pure ethanol.\nOnly in an intermediate window of 67.5% < f_e < 80% do we find sessile\nplasmonic bubbles with a highly nontrivial temporal evolution, in which as a\nfunction of time three phases can be discerned. (1) In the first phase, the\nmicrobubbles grow, while wiggling. (2) As soon as the wiggling stops, the\nmicrobubbles enter the second phase in which they suddenly shrink, followed by\n(3) a steady reentrant growth phase. Our experiments reveal that the sudden\nshrinkage of the microbubbles in the second regime is caused by a depinning\nevent of the three phase contact line. We systematically vary the ethanol\nconcentration, laser power, and laser spot size to unravel water recondensation\nas the underlying mechanism of the sudden bubble shrinkage in phase 2."

We perform an\nanalysis of different parameter sharing/reduction methods and develop the\nSubformer, a parameter efficient Transformer-based model which combines the\nnewly proposed Sandwich-style parameter sharing technique - designed to\novercome the deficiencies in naive cross-layer parameter sharing for generative\nmodels - and self-attentive embedding factorization (SAFE).

This is particularly true in the elastic regime: The cycle-skipping\nphenomenon is more severe in elastic FWI compared to acoustic FWI, due to the\nshort S-wave wavelength. In this paper, we extend our work on extrapolated FWI\n(EFWI) by proposing to synthesize the low frequencies of multi-component\nelastic seismic records, and use those \"artificial\" low frequencies to seed the\nfrequency sweep of elastic FWI. Our solution involves deep learning: we\nseparately train the same convolutional neural network (CNN) on two training\ndatasets, one with vertical components and one with horizontal components of\nparticle velocities, to extrapolate the low frequencies of elastic data. The\narchitecture of this CNN is designed with a large receptive field, by either\nlarge convolutional kernels or dilated convolution. Numerical examples on the\nMarmousi2 model show that the 2-4Hz low frequency data extrapolated from\nband-limited data above 4Hz provide good starting models for elastic FWI of\nP-wave and S-wave velocities. Additionally, we study the generalization ability\nof the proposed neural network over different physical models.

+content = "In this paper we study random representations of fundamental groups of\nsurfaces into special unitary groups. The random model we use is based on a\nsymplectic form on moduli space due to Atiyah, Bott, and Goldman. Let\n$\\Sigma_{g}$ denote a topological surface of genus $g\\geq2$. We establish the\nexistence of a large $n$ asymptotic expansion, to any fixed order, for the\nexpected value of the trace of any fixed element of $\\pi_{1}(\\Sigma_{g})$ under\na random representation of $\\pi_{1}(\\Sigma_{g})$ into $\\mathsf{SU}(n)$. Each\nsuch expected value involves a contribution from all irreducible\nrepresentations of $\\mathsf{SU}(n)$. The main technical contribution of the\npaper is effective analytic control of the entire contribution from irreducible\nrepresentations outside finite sets of carefully chosen rational families of\nrepresentations."

+content = "There is a growing interest in the learning-to-learn paradigm, also known as\nmeta-learning, where models infer on new tasks using a few training examples.\nRecently, meta-learning based methods have been widely used in few-shot\nclassification, regression, reinforcement learning, and domain adaptation. The\nmodel-agnostic meta-learning (MAML) algorithm is a well-known algorithm that\nobtains model parameter initialization at meta-training phase. In the meta-test\nphase, this initialization is rapidly adapted to new tasks by using gradient\ndescent. However, meta-learning models are prone to overfitting since there are\ninsufficient training tasks resulting in over-parameterized models with poor\ngeneralization performance for unseen tasks. In this paper, we propose a\nBayesian neural network based MAML algorithm, which we refer to as the B-SMALL\nalgorithm. The proposed framework incorporates a sparse variational loss term\nalongside the loss function of MAML, which uses a sparsifying approximated KL\ndivergence as a regularizer. We demonstrate the performance of B-MAML using\nclassification and regression tasks, and highlight that training a sparsifying\nBNN using MAML indeed improves the parameter footprint of the model while\nperforming at par or even outperforming the MAML approach. We also illustrate\napplicability of our approach in distributed sensor networks, where sparsity\nand meta-learning can be beneficial."

+content = "Surgical skill directly affects surgical procedure outcomes; thus, effective\ntraining is needed to ensure satisfactory results. Many objective assessment\nmetrics have been developed and some are widely used in surgical training\nsimulators. These objective metrics provide the trainee with descriptive\nfeedback about their performance however, often lack feedback on how to proceed\nto improve performance. The most effective training method is one that is\nintuitive, easy to understand, personalized to the user and provided in a\ntimely manner. We propose a framework to enable user-adaptive training using\nnear-real-time detection of performance, based on intuitive styles of surgical\nmovements (e.g., fluidity, smoothness, crispness, etc.), and propose a haptic\nfeedback framework to assist with correcting styles of movement. We evaluate\nthe ability of three types of force feedback (spring, damping, and spring plus\ndamping feedback), computed based on prior user positions, to improve different\nstylistic behaviors of the user during kinematically constrained reaching\nmovement tasks. The results indicate that four out of the six styles studied\nhere were statistically significantly improved (p<0.05) using spring guidance\nforce feedback and a significant reduction in task time was also found using\nspring feedback. The path straightness and targeting error in the task were\nother task performance metrics studied which were improved significantly using\nthe spring-damping feedback. This study presents a groundwork for adaptive\ntraining in robotic surgery based on near-real-time human-centric models of\nsurgical behavior."

Our approach not only outperforms previous methods in the\nfew-shot setting, but also rivals specialised neural retrievers, even when\nin-domain training data is abundant.

The ID fermion operators\nare introduced through the Laurent expansion of finite-dimensional fermion\noperators with respect to the degrees of freedom of the fermions related to a\nmean-field potential. The mean-field potential degrees of freedom of fermions\narise from the gauge degrees of freedom of the fermions. We study a relation\nbetween the SCF theory and the soliton theory from the viewpoint of dynamics on\nan infinite-dimensional Grassmannian (Gr) with Lie algebras. Behind the Gr, the\nassociative affine Kac-Moody algebras play a crucial role to determine a\ndynamics of the fermion systems."

We see as time passes,\nsignificant changes come in the present era, which begins with Green\nRevolution. Due to improper knowledge of plant diseases, farmers use\nfertilizers in excess, which ultimately degrade the quality of food. Earlier\nfarmers use experts to determine the type of plant disease, which was expensive\nand time-consuming. In today time, Image processing is used to recognize and\ncatalog plant diseases using the lesion region of plant leaf, and there are\ndifferent modus-operandi for plant disease scent from leaf using Neural\nNetworks (NN), Support Vector Machine (SVM), and others. In this paper, we\nimproving the architecture of the Neural Networking by working on ten different\ntypes of training algorithms and the proper choice of neurons in the concealed\nlayer.

+content = "In this paper, we introduce the locally conservative enriched immersed finite\nelement method (EIFEM) to tackle the elliptic problem with interface. The\nimmersed finite element is useful for handling interface with mesh unfit with\nthe interface. However, all the currently available method under IFEM framework\nmay not be designed to consider the flux conservation. We provide an efficient\nand effective remedy for this issue by introducing a local piecewise constant\nenrichment, which provides the locally conservative flux. We have also\nconstructed and analyzed an auxiliary space preconditioner for the resulting\nsystem based on the application of algebraic multigrid method. The new\nobservation in this work is that by imposing strong Dirichlet boundary\ncondition for the standard IFEM part of EIFEM, we are able to remove the zero\neigen-mode of the EIFEM system while still imposing the Dirichlet boundary\ncondition weakly assigned to the piecewise constant enrichment part of EIFEM. A\ncouple of issues relevant to the piecewise constant enrichment given for the\nmesh unfit to the interface has been discussed and clarified as well. Numerical\ntests are provided to confirm the theoretical development."

Voltage sensitivity studies are conducted to\nuncover the dependency between nodal voltage changes and the reactive power\ninjections at nodes with smart PV inverters. A fast incremental clustering\nmethod is developed to divide the distribution feeder into weakly coupled zones\nbased on correlations of nodal voltage sensitivities. Because each zone is\nweakly coupled, voltage of each zone can be controlled independently. Thus, in\neach zone, a rule-based voltage controller will dispatch PV smart inverters to\nprovide reactive power control for correcting the over/under voltages. An\nactual distribution feeder in North Carolina is used as a test bed. Simulation\nresults show that the proposed zonal based Volt/VAR control mechanism can\nmaintain the voltage in the distribution system within limits and solves faster\nthan the centralized controller."

In this paper, we study a new\nmulti-IRS aided massive multiple-input multiple-output (MIMO) system, where a\nmulti-antenna BS transmits independent messages to a set of remote\nsingle-antenna users using orthogonal beams that are subsequently reflected by\ndifferent groups of IRSs via their respective multi-hop passive beamforming\nover pairwise line-of-sight (LoS) links. We aim to select optimal IRSs and\ntheir beam routing path for each of the users, along with the active/passive\nbeamforming at the BS/IRSs, such that the minimum received signal power among\nall users is maximized. This problem is particularly difficult to solve due to\na new type of path separation constraints for avoiding the IRS-reflected signal\ninduced interference among different users. To tackle this difficulty, we first\nderive the optimal BS/IRS active/passive beamforming solutions based on their\npractical codebooks given the reflection paths. Then we show that the resultant\nmulti-beam multi-hop routing problem can be recast as an equivalent\ngraph-optimization problem, which is however NP-complete. To solve this\nchallenging problem, we propose an efficient recursive algorithm to partially\nenumerate the feasible routing solutions, which is able to effectively balance\nthe performance-complexity trade-off. Numerical results demonstrate that the\nproposed algorithm achieves near-optimal performance with low complexity and\noutperforms other benchmark schemes. Useful insights into the optimal\nmulti-beam multi-hop routing design are also drawn under different setups of\nthe multi-IRS aided massive MIMO network."

+content = "This paper presents a new chaotic system having four attractors, including\ntwo fixed point attractors and two symmetrical chaotic strange attractors.\nDynamical properties of the system, viz. sensitive dependence on initial\nconditions, Lyapunov spectrum, strangeness measure, attraction basin, including\nthe class and size of it, existence of strange attractor, bifurcation analysis,\nmultistability, electronic circuit design, and hardware implementation, are\nrigorously treated. Numerical computations are used to compute the basin of\nattraction and show that the system has a far-reaching composite basin of\nattraction. Such a basin of attraction is vital for engineering applications.\nMoreover, a circuit model of the system is realized using analog electronic\ncomponents. A procedure is detailed for converting the system parameters into\ncorresponding electronic component values such as the circuital resistances\nwhile ensuring the dynamic ranges are bounded. Besides, the system is used as\nthe source of control inputs for independent navigation of a differential drive\nmobile robot, which is subject to the Pfaffian velocity constraint. Due to the\nproperties of sensitivity on initial conditions and topological mixing, the\nrobot's path becomes unpredictable and guaranteed to scan the workspace,\nrespectively."

+content = "The precise measurement of the positron spectrum by AMS-02 reveals a sharp\ndropoff above ∼ 284 GeV. However, the AMS-02 electron spectrum shows a\npower-law from ∼ 40 GeV to ∼ 1 TeV without significant features. We\npropose that the difference of spectral features between electrons and\npositrons indicates the existence of a nearby source component of primary\nelectrons. Taking into account the observational results of the positron\nexcess, the spectral softenings of cosmic ray protons and helium nuclei, and\nthe energy-dependences of the large-scale anisotropies of cosmic rays, we\nsuggest that the scenario of supernova remnant origin of cosmic rays with\nnon-negligible contribution from a nearby source can successfully account for\nmost of the observations of cosmic rays below PeV energies. The Geminga pulsar\nand its past supernova remnant might be a proper candidate of the nearby\nsource."
