Volume growth in the component of fibered twists | For a Liouville domain $W$ whose boundary admits a periodic Reeb flow, we can
consider the connected component $[\tau] \in \pi_0(\text{Symp}^c(\widehat W))$
of fibered twists. In this paper, we investigate an entropy-type invariant,
called the slow volume growth, of the component $[\tau]$ and give a uniform

Scalar Reduction of a Neural Field Model with Spike Frequency Adaptation | We study a deterministic version of a one- and two-dimensional attractor
neural network model of hippocampal activity first studied by Itskov et al
2011. We analyze the dynamics of the system on the ring and torus domain with
an even periodized weight matrix, assum- ing weak and slow spike frequency

Revisiting Elementary Denotational Semantics | Operational semantics have been enormously successful, in large part due to
its flexibility and simplicity, but they are not compositional. Denotational
semantics, on the other hand, are compositional but the lattice-theoretic
models are complex and difficult to scale to large languages. However, there
are elementary... | 1 | 0 | 0 | 0 | 0 | 0 |
Dirac Composite Fermion - A Particle-Hole Spinor | The particle-hole (PH) symmetry at half-filled Landau level requires the
relationship between the flux number N_phi and the particle number N on a
sphere to be exactly N_phi - 2(N-1) = 1. The wave functions of composite
fermions with 1/2 "orbital spin", which contributes to the shift "1" in the

Safe Adaptive Importance Sampling | Importance sampling has become an indispensable strategy to speed up
optimization algorithms for large-scale applications. Improved adaptive

which changes during optimization - enjoy favorable theoretical properties, but

Secure Grouping Protocol Using a Deck of Cards | We consider a problem, which we call secure grouping, of dividing a number of
parties into some subsets (groups) in the following manner: Each party has to
know the other members of his/her group, while he/she may not know anything
about how the remaining parties are divided (except for certain public

Categorically closed topological groups | Let $\mathcal C$ be a subcategory of the category of topologized semigroups
and their partial continuous homomorphisms. An object $X$ of the category
${\mathcal C}$ is called ${\mathcal C}$-closed if for each morphism $f:X\to Y$
of the category ${\mathcal C}$ the image $f(X)$ is closed in $Y$. In the paper

Extracting significant signal of news consumption from social networks: the case of Twitter in Italian political elections | According to the Eurobarometer report about EU media use of May 2018, the

$10^6$ tweets exchanged during the last Italian elections. By using an

Annealed Generative Adversarial Networks | We introduce a novel framework for adversarial training where the target

Attitude Control of Spacecraft Formations Subject To Distributed Communication Delays | This paper considers the problem of achieving attitude consensus in
spacecraft formations with bounded, time-varying communication delays between
spacecraft connected as specified by a strongly connected topology. A state

(via LMIs) and a... | 1 | 0 | 0 | 0 | 0 | 0 |
Cloud Radiative Effect Study Using Sky Camera | The analysis of clouds in the earth's atmosphere is important for a variety

generation. In this paper, we focus our attention on the impact of cloud on the

On Testing Machine Learning Programs | Nowadays, we are witnessing a wide adoption of Machine learning (ML) models

personal assistan... | 1 | 0 | 0 | 0 | 0 | 0 |
Scalable and Efficient Statistical Inference with Estimating Functions in the MapReduce Paradigm for Big Data | The theory of statistical inference along with the strategy of
divide-and-conquer for large- scale data analysis has recently attracted

the development of statistic... | 0 | 0 | 0 | 1 | 0 | 0 |
Instability of pulses in gradient reaction-diffusion systems: A symplectic approach | In a scalar reaction-diffusion equation, it is known that the stability of a
steady state can be determined from the Maslov index, a topological invariant
that counts the state's critical points. In particular, this implies that pulse
solutions are unstable. We extend this picture to pulses in reaction-diffusion

Consistency of the plug-in functional predictor of the Ornstein-Uhlenbeck process in Hilbert and Banach spaces | New results on functional prediction of the Ornstein-Uhlenbeck process in an
autoregressive Hilbert-valued and Banach-valued frameworks are derived.
Specifically, consistency of the maximum likelihood estimator of the
autocorrelation operator, and of the associated plug-in predictor is obtained
in both frameworks.

Analysis of Sequence Polymorphism of LINEs and SINEs in Entamoeba histolytica | The goal of this dissertation is to study the sequence polymorphism in

of these elements. Two datasets of retrotransposons of Entamoeba histolytica

Classification of digital affine noncommutative geometries | It is known that connected translation invariant $n$-dimensional
noncommutative differentials $d x^i$ on the algebra $k[x^1,\cdots,x^n]$ of
polynomials in $n$-variables over a field $k$ are classified by commutative
algebras $V$ on the vector space spanned by the coordinates. This data also

The vectorial Ribaucour transformation for submanifolds of constant sectional curvature | We obtain a reduction of the vectorial Ribaucour transformation that

such submanifolds starting with a given one and a vector-valued solution of a

Social Networks through the Prism of Cognition | Human relations are driven by social events - people interact, exchange

These events leave traces in human memory. The initial strength of a trace

continuously weakens... | 1 | 0 | 0 | 0 | 0 | 0 |
Metriplectic Integrators for the Landau Collision Operator | We present a novel framework for addressing the nonlinear Landau collision

Eliminating higher-multiplicity intersections in the metastable dimension range | The $r$-fold analogues of Whitney trick were `in the air' since 1960s.
However, only in this century they were stated, proved and applied to obtain

apply a version of the $r$-fold Whitney trick when general position $r$-tuple

Lagrangian Transport Through Surfaces in Compressible Flows | A material-based, i.e., Lagrangian, methodology for exact integration of flux

paper, we first generalize this framework to general compressible flows,
