which is a key ecological issue. In order to improve the resulting poor
performances a new model-free control setting and its corresponding
"intelligent" controller a... | 1 | 0 | 1 | 0 | 0 | 0 |
The interaction of Airy waves and solitons in the three-wave system | We employ the generic three-wave system, with the $\chi ^{(2)}$ interaction
between two components of the fundamental-frequency (FF) wave and
second-harmonic (SH) one, to consider collisions of truncated Airy waves (TAWs)
and three-wave solitons in a setting which is not available in other nonlinear
systems. The adva... | 0 | 1 | 0 | 0 | 0 | 0 |
A penalty criterion for score forecasting in soccer | This note proposes a penalty criterion for assessing correct score
forecasting in a soccer match. The penalty is based on hierarchical priorities
for such a forecast i.e., i) Win, Draw and Loss exact prediction and ii)
normalized Euclidian distance between actual and forecast scores. The procedure
is illustrated on t... | 0 | 0 | 0 | 1 | 0 | 0 |
A robust RUV-testing procedure via gamma-divergence | Identification of differentially expressed genes (DE-genes) is commonly
conducted in modern biomedical researches. However, unwanted variation
inevitably arises during the data collection process, which could make the
detection results heavily biased. It is suggested to remove the unwanted
variation while keeping the... | 0 | 0 | 0 | 1 | 0 | 0 |
On the Distribution, Model Selection Properties and Uniqueness of the Lasso Estimator in Low and High Dimensions | We derive expressions for the finite-sample distribution of the Lasso
estimator in the context of a linear regression model with normally distributed
errors in low as well as in high dimensions by exploiting the structure of the
optimization problem defining the estimator. In low dimensions we assume full
rank of the... | 0 | 0 | 1 | 1 | 0 | 0 |
Transductive Boltzmann Machines | We present transductive Boltzmann machines (TBMs), which firstly achieve
transductive learning of the Gibbs distribution. While exact learning of the
Gibbs distribution is impossible by the family of existing Boltzmann machines
due to combinatorial explosion of the sample space, TBMs overcome the problem
by adaptivel... | 0 | 0 | 0 | 1 | 0 | 0 |
Human-Robot Trust Integrated Task Allocation and Symbolic Motion planning for Heterogeneous Multi-robot Systems | This paper presents a human-robot trust integrated task allocation and motion
planning framework for multi-robot systems (MRS) in performing a set of tasks
concurrently. A set of task specifications in parallel are conjuncted with MRS
to synthesize a task allocation automaton. Each transition of the task
allocation a... | 1 | 0 | 0 | 0 | 0 | 0 |
A five-decision testing procedure to infer on unidimensional parameter | A statistical test can be seen as a procedure to produce a decision based on
observed data, where some decisions consist of rejecting a hypothesis (yielding
a significant result) and some do not, and where one controls the probability
to make a wrong rejection at some pre-specified significance level. Whereas

PubMed 200k RCT: a Dataset for Sequential Sentence Classification in Medical Abstracts | We present PubMed 200k RCT, a new dataset based on PubMed for sequential

sentence of each abstract is labeled with their role in the abstract using one

Convergence radius of perturbative Lindblad driven non-equilibrium steady states | We address the problem of analyzing the radius of convergence of perturbative
expansion of non-equilibrium steady states of Lindblad driven spin chains. A
simple formal approach is developed for systematically computing the
perturbative expansion of small driven systems. We consider the paradigmatic
model of an open ... | 0 | 1 | 0 | 0 | 0 | 0 |
A 2D metamaterial with auxetic out-of-plane behavior and non-auxetic in-plane behavior | Customarily, in-plane auxeticity and synclastic bending behavior (i.e.
out-of-plane auxeticity) are not independent, being the latter a manifestation
of the former. Basically, this is a feature of three-dimensional bodies. At
variance, two-dimensional bodies have more freedom to deform than
three-dimensional ones. He... | 0 | 1 | 0 | 0 | 0 | 0 |
Isolated Loops in Quantum Feedback Networks | A scheme making use of an isolated feedback loop was recently proposed in
\cite{GP_} for creating an arbitrary bilinear Hamiltonian interaction between
two multi-mode Linear Quantum Stochastic Systems (LQSSs). In this work we
examine the presence of an isolated feedback loop in a general SLH network, and

Distance-based Depths for Directional Data | Directional data are constrained to lie on the unit sphere of~$\mathbb{R}^q$
for some~$q\geq 2$. To address the lack of a natural ordering for such data,
depth functions have been defined on spheres. However, the depths available
either lack flexibility or are so computationally expensive that they can only
be used f... | 0 | 0 | 1 | 1 | 0 | 0 |
Two-dimensional Schrödinger symmetry and three-dimensional breathers and Kelvin-ripple complexes as quasi-massive-Nambu-Goldstone modes | Bose-Einstein condensates (BECs) confined in a two-dimensional (2D) harmonic
trap are known to possess a hidden 2D Schrödinger symmetry, that is, the
Schrödinger symmetry modified by a trapping potential. Spontaneous breaking
of this symmetry gives rise to a breathing motion of the BEC, whose oscillation

Groupoid of morphisms of groupoids | In this paper we construct two groupoids from morphisms of groupoids, with
one from a categorical viewpoint and the other from a geometric viewpoint. We
show that for each pair of groupoids, the two kinds of groupoids of morphisms
are equivalent. Then we study the automorphism groupoid of a groupoid.

Spin alignment of stars in old open clusters | Stellar clusters form by gravitational collapse of turbulent molecular
clouds, with up to several thousand stars per cluster. They are thought to be

understanding of star formation, a fundamental problem in astrophysics. The
initial conditions o... | 0 | 1 | 0 | 0 | 0 | 0 |
Global well-posedness of critical surface quasigeostrophic equation on the sphere | In this paper we prove global well-posedness of the critical surface
quasigeostrophic equation on the two dimensional sphere building on some

known pointwise inequality for fractional laplacians as in the work of

On the Limitation of Local Intrinsic Dimensionality for Characterizing the Subspaces of Adversarial Examples | Understanding and characterizing the subspaces of adversarial examples aid in

A properly embedded holomorphic disc in the ball with finite area and dense boundary curve | In this paper we construct a properly embedded holomorphic disc in the unit
ball $\mathbb{B}^2$ of $\mathbb{C}^2$ having a surprising combination of

bounded holomorphic function on $\mathbb{B}^2$; on the other hand, its boundary
curve is e... | 0 | 0 | 1 | 0 | 0 | 0 |
Kähler differential algebras for 0-dimensional schemes | Given a 0-dimensional scheme in a projective space $\mathbb{P}^n$ over a

$\Omega^m_{R/K}$ of Kähler differential $m$-forms, we determine many values

Benchmarks and reliable DFT results for spin-crossover complexes | DFT is used throughout nanoscience, especially when modeling spin-dependent

The Road to Success: Assessing the Fate of Linguistic Innovations in Online Communities | We investigate the birth and diffusion of lexical innovations in a large

adopters. Fin... | 1 | 0 | 0 | 0 | 0 | 0 |
