A spectral approach to transit timing variations | The high planetary multiplicity revealed by Kepler implies that Transit Time

Distinct dynamical behavior in random and all-to-all neuronal networks | Neuronal network dynamics depends on network structure. It is often assumed

Fluorescent Troffer-powered Internet of Things: An Experimental Study of Electric-field Energy Harvesting | A totally new energy harvesting architecture that exploits ambient
electric-field (E-field) emitting from fluorescent light fixtures is presented.
A copper plate, 50 x 50 cm in size, is placed in between the ambient field to
extract energy by capacitive coupling. A low voltage prototype is designed,
structured and te... | 1 | 1 | 0 | 0 | 0 | 0 |
Parallel Simultaneous Perturbation Optimization | Stochastic computer simulations enable users to gain new insights into
complex physical systems. Optimization is a common problem in this context:
users seek to find model inputs that maximize the expected value of an
objective function. The objective function, however, is time-intensive to
evaluate, and cannot be di... | 0 | 0 | 1 | 0 | 0 | 0 |
Achievable Rate Region of Non-Orthogonal Multiple Access Systems with Wireless Powered Decoder | Non-orthogonal multiple access (NOMA) is a candidate multiple access scheme
in 5G systems for the simultaneous access of tremendous number of wireless
nodes. On the other hand, RF-enabled wireless energy harvesting is a promising
technology for self-sustainable wireless nodes. In this paper, we consider a

Agent-based model for the origins of scaling in human language | Background/Introduction: The Zipf's law establishes that if the words of a
(large) text are ordered by decreasing frequency, the frequency versus the rank
decreases as a power law with exponent close to -1. Previous work has stressed
that this pattern arises from a conflict of interests of the participants of

Credible Review Detection with Limited Information using Consistency Analysis | Online reviews provide viewpoints on the strengths and shortcomings of
products/services, influencing potential customers' purchasing decisions.
However, the proliferation of non-credible reviews -- either fake (promoting/

entails the problem... | 1 | 0 | 0 | 1 | 0 | 0 |
The Asymptotically Self-Similar Regime for the Einstein Vacuum Equations | We develop a local theory for the construction of singular spacetimes in all
spacetime dimensions which become asymptotically self-similar as the

asymptotic expansion... | 0 | 0 | 1 | 0 | 0 | 0 |
Kinematics and dynamics of an egg-shaped robot with a gyro driven inertia actuator | The manuscript discusses still preliminary considerations with regard to the
dynamics and kinematics of an egg shaped robot with an gyro driven inertia
actuator. The method of calculation follows the idea that we would like to
express the entire dynamic equations in terms of moments instead of forces.
Also we avoid t... | 1 | 0 | 0 | 0 | 0 | 0 |
Cloaking and anamorphism for light and mass diffusion | We first review classical results on cloaking and mirage effects for
electromagnetic waves. We then show that transformation optics allows the
masking of objects or produces mirages in diffusive regimes. In order to
achieve this, we consider the equation for diffusive photon density in
transformed coordinates, which ... | 0 | 1 | 1 | 0 | 0 | 0 |
Super Rogers-Szegö polynomials associated with $BC_N$ type of Polychronakos spin chains | As is well known, multivariate Rogers-Szegö polynomials are closely
connected with the partition functions of the $A_{N-1}$ type of Polychronakos
spin chains having long-range interactions. Applying the `freezing trick', here
we derive the partition functions for a class of $BC_N$ type of Polychronakos
spin chains co... | 0 | 1 | 0 | 0 | 0 | 0 |
A statistical physics approach to learning curves for the Inverse Ising problem | Using methods of statistical physics, we analyse the error of learning
couplings in large Ising models from independent data (the inverse Ising
problem). We concentrate on learning based on local cost functions, such as the
pseudo-likelihood method for which the couplings are inferred independently for
each spin. Ass... | 0 | 1 | 0 | 1 | 0 | 0 |
Fast Kinetic Scheme : efficient MPI parallelization strategy for 3D Boltzmann equation | In this paper we present a parallelization strategy on distributed memory
systems for the Fast Kinetic Scheme --- a semi-Lagrangian scheme developed in
[J. Comput. Phys., Vol. 255, 2013, pp 680-698] for solving kinetic equations.
The original algorithm was proposed for the BGK approximation of the collision

Finding a Feasible Initial Solution for Flatness-Based Multi-Link Manipulator Motion Planning under State and Control Constraints | In this paper, we present a method to initialize at a feasible point and

construct an initial feasible solution by analyzing the final time effect for

Techniques for visualizing LSTMs applied to electrocardiograms | This paper explores four different visualization techniques for long
short-term memory (LSTM) networks applied to continuous-valued time series. On

a specific focus... | 1 | 0 | 0 | 1 | 0 | 0 |
Obtaining Accurate Probabilistic Causal Inference by Post-Processing Calibration | Discovery of an accurate causal Bayesian network structure from observational

that th... | 1 | 0 | 0 | 1 | 0 | 0 |
Faster Bounding Box Annotation for Object Detection in Indoor Scenes | This paper proposes an approach for rapid bounding box annotation for object

Direct-Manipulation Visualization of Deep Networks | The recent successes of deep learning have led to a wave of interest from
