We consider the spread of an infectious disease in a heterogeneous environment modeled as network patches. focus on invasibility disease, quantified by corresponding value approximation to basic reproduction number, $\mathcal{R}_0$, and study how changes structure affect $\mathcal{R}_0$. provide detailed analysis for two model networks, star path, discuss that yield largest decrease develop bot...

Landscape features may serve as either barriers or gateways to the spread of certain infectious diseases, and understanding the way geographic structure impacts disease spread could lead to improved containment strategies. Here, we focus on modeling the space-time diffusion process of a raccoon rabies outbreak across several states in the Eastern United States. Specifically, we measure the impa...

Context. The image degradation produced by atmospheric turbulence and optical aberrations is usually alleviated using post-facto image reconstruction techniques, even when observing with adaptive optics systems. Aims. These techniques rely on the development of the wavefront using Zernike functions and the non-linear optimization of a certain metric. The resulting optimization procedure is comp...

Spread mooring systems are associated with high level uncertainties and risks during tanker loading/ unloading operations. In addition, the design of such complex systems consists of many subjective and imprecise parameters. Therefore, in the present study, a fuzzy based decision support methodology is designed to overcome aforementioned characteristics. The fuzzy methodology incorporates quali...

The coronavirus disease pandemic has spread to every corner of the world and affected our practice as healthcare professionals, Morocco experienced a period strict containment on March, April May 2020. This confinement gave notable social economic changes. Through this analytic study we compare epidemiology burns admitted burn’s unit university hospital Mohammed VI Marrakech 2020 May2019, have ...

We prove a conjecture of [3] giving a closed form formula for the norm of the Jack polynomials in superspace with respect to a certain scalar product. The proof is mainly combinatorial and relies on the explicit expression in terms of admissible tableaux of the non-symmetric Jack polynomials. In the final step of the proof appears an identity on weighted sums of partitions that we demonstrate u...

The paper is a contribution both to the theoretical foundations and to the actual construction of efficient automatizable proof procedures for non-classical logics. We focus here on the case of finite-valued logics, and exhibit: (i) a mechanism for producing a classic-like description of them in terms of an effective variety of bivalent semantics; (ii) a mechanism for extracting, from the bival...
