To the Acceleration of Charged Particles with Travelling Laser Focus | We describe here the latest results of calculations with FlexPDE code of
wake-fields induced by the bunch in micro-structures. These structures,
illuminated by swept laser bust, serve for acceleration of charged particles.
The basis of the scheme is a fast sweeping device for the laser bunch. After

Affiliation networks with an increasing degree sequence | Affiliation network is one kind of two-mode social network with two different
sets of nodes (namely, a set of actors and a set of social events) and edges
representing the affiliation of the actors with the social events. Although a
number of statistical models are proposed to analyze affiliation networks, the

Coarse Grained Parallel Selection | We analyze the running time of the Saukas-Song algorithm for selection on a
coarse grained multicomputer without expressing the running time in terms of
communication rounds. This shows that while in the best case the Saukas-Song
algorithm runs in asymptotically optimal time, in general it does not. We
propose other ... | 1 | 0 | 0 | 0 | 0 | 0 |
An IoT Analytics Embodied Agent Model based on Context-Aware Machine Learning | Agent-based Internet of Things (IoT) applications have recently emerged as

agriculture. Howeve... | 1 | 0 | 0 | 0 | 0 | 0 |
Aggregation of Classifiers: A Justifiable Information Granularity Approach | In this study, we introduce a new approach to combine multi-classifiers in an

concepts of in... | 1 | 0 | 0 | 1 | 0 | 0 |
FRET-based nanocommunication with luciferase and channelrhodopsin molecules for in-body medical systems | The paper is concerned with an in-body system gathering data for medical

Neural Sequence Model Training via $α$-divergence Minimization | We propose a new neural sequence model training method in which the objective

Output Range Analysis for Deep Neural Networks | Deep neural networks (NN) are extensively used for machine learning tasks
such as image classification, perception and control of autonomous systems.

applications. Thus, there is a pressing need for developing techniques to
verify neural networks t... | 1 | 0 | 0 | 1 | 0 | 0 |
Projection Theorems of Divergences and Likelihood Maximization Methods | Projection theorems of divergences enable us to find reverse projection of a
divergence on a specific statistical model as a forward projection of the
divergence on a different but rather "simpler" statistical model, which, in
turn, results in solving a system of linear equations. Reverse projection of
divergences ar... | 0 | 0 | 1 | 1 | 0 | 0 |
Optimal Timing in Dynamic and Robust Attacker Engagement During Advanced Persistent Threats | Advanced persistent threats (APTs) are stealthy attacks which make use of
social engineering and deception to give adversaries insider access to
networked systems. Against APTs, active defense technologies aim to create and
exploit information asymmetry for defenders. In this paper, we study a scenario
in which a pow... | 1 | 0 | 0 | 0 | 0 | 0 |
The Mismeasure of Mergers: Revised Limits on Self-interacting Dark Matter in Merging Galaxy Clusters | In an influential recent paper, Harvey et al (2015) derive an upper limit to
the self-interaction cross section of dark matter ($\sigma_{\rm DM} < 0.47$
cm$^2$/g at 95\% confidence) by averaging the dark matter-galaxy offsets in a

International crop trade networks: The impact of shocks and cascades | Analyzing available FAO data from 176 countries over 21 years, we observe an
increase of complexity in the international trade of maize, rice, soy, and
wheat. A larger number of countries play a role as producers or intermediaries,
either for trade or food processing. In consequence, we find that the trade

Winning on the Merits: The Joint Effects of Content and Style on Debate Outcomes | Debate and deliberation play essential roles in politics and government, but
most models presume that debates are won mainly via superior style or agenda
control. Ideally, however, debates would be won on the merits, as a function of
which side has the stronger arguments. We propose a predictive model of debate

Gene regulatory networks: a primer in biological processes and statistical modelling | Modelling gene regulatory networks not only requires a thorough understanding

Mathematical Knowledge and the Role of an Observer: Ontological and epistemological aspects | As David Berlinski writes (1997), the existence and nature of mathematics is

emphasis on mathematics as an advanced system of knowledge. This knowledge

Linking High-Energy Cosmic Particles by Black-Hole Jets Embedded in Large-Scale Structures | The origin of ultrahigh-energy cosmic rays (UHECRs) is a half-century old
enigma (Linsley 1963). The mystery has been deepened by an intriguing
coincidence: over ten orders of magnitude in energy, the energy generation
rates of UHECRs, PeV neutrinos, and isotropic sub-TeV gamma rays are
comparable, which hints at a g... | 0 | 1 | 0 | 0 | 0 | 0 |
Quantifying and suppressing ranking bias in a large citation network | It is widely recognized that citation counts for papers from different fields

Posterior Concentration for Bayesian Regression Trees and Forests | Since their inception in the 1980's, regression trees have been one of the
