On $(σ,δ)$-skew McCoy modules | Let $(\sigma,\delta)$ be a quasi derivation of a ring $R$ and $M_R$ a right
$R$-module. In this paper, we introduce the notion of $(\sigma,\delta)$-skew
McCoy modules which extends the notion of McCoy modules and $\sigma$-skew McCoy
modules. This concept can be regarded also as a generalization of

Bivariate Exponentiated Generalized Linear Exponential Distribution with Applications in Reliability Analysis | The aim of this paper, is to define a bivariate exponentiated generalized

Soft-proton exchange on Magnesium-oxide-doped substrates a route toward efficient and power-resistant nonlinear converters | Despite its attractive features, Congruent-melted Lithium Niobate (CLN)
suffers from Photo-Refractive Damage (PRD). This light-induced refractive-index
change hampers the use of CLN when high-power densities are in play, a typical
regime in integrated optics. The resistance to PRD can be largely improved by

Recursive constructions and their maximum likelihood decoding | We consider recursive decoding techniques for RM codes, their subcodes, and

decoding with feasible complexity.

Impact of Detour-Aware Policies on Maximizing Profit in Ridesharing | This paper provides efficient solutions to maximize profit for commercial

Optimal lower exponent for the higher gradient integrability of solutions to two-phase elliptic equations in two dimensions | We study the higher gradient integrability of distributional solutions $u$ to
the equation $div(\sigma \nabla u) = 0$ in dimension two, in the case when the
essential range of $\sigma$ consists of only two elliptic matrices, i.e.,
$\sigma\in\{\sigma_1, \sigma_2\}$ a.e. in $\Omega$.

On the existence of young embedded clusters at high Galactic latitude | Careful analyses of photometric and star count data available for the nine
putative young clusters identified by Camargo et al. (2015, 2016) at high

most are not significant density enhancements above field level. 2MASS colours

The risk of contagion spreading and its optimal control in the economy | The global crisis of 2008 provoked a heightened interest among scientists to

the spread of a disease among a population is similar to the contagion process

A Learning-to-Infer Method for Real-Time Power Grid Topology Identification | Identifying arbitrary topologies of power networks in real time is a

the network. Optimizing ... | 1 | 0 | 0 | 1 | 0 | 0 |
Convergence analysis of belief propagation for pairwise linear Gaussian models | Gaussian belief propagation (BP) has been widely used for distributed

Banach-Alaoglu theorem for Hilbert $H^*$-module | We provided an analogue Banach-Alaoglu theorem for Hilbert $H^*$-module. We

$\Lambda$-weak$^*$ topology.

An Overflow Free Fixed-point Eigenvalue Decomposition Algorithm: Case Study of Dimensionality Reduction in Hyperspectral Images | We consider the problem of enabling robust range estimation of eigenvalue

rithms in fixed-point arithmetic. Working towards an effective fixed-point

Incentivized Advertising: Treatment Effect and Adverse Selection | Incentivized advertising is a new ad format that is gaining popularity in

users for watching an ad. An endemic issue here is adverse selection, where
reward-seeking users select into incentivized ad placements to obtain rewards.

Prospects for indirect MeV Dark Matter detection with Gamma Rays in light of Cosmic Microwave Background Constraints | The self-annihilation of dark matter particles with mass in the MeV range can

Special cases of the orbifold version of Zvonkine's $r$-ELSV formula | We prove the orbifold version of Zvonkine's $r$-ELSV formula in two special

case of any $r\geq 1$ for genus $g=0$.

A note on optimization with Morse polynomials | In this paper we prove that the gradient ideal of a Morse polynomial is
