The performance of heat transfer materials is strongly dependent on physical characteristics such as viscosity, thermal conductivity, and density. Among these, evolving thermal conductivity is a critical element in fluid heat transmission. In general

In this study, local fuzzy fractional partial differential equations (LFFPDEs) are considered using a hybrid local fuzzy fractional approach. Fractal model behavior can be represented using fuzzy partial differential equations (PDEs) with local fract

We discuss the notion of Volterra, l-Volterra and separable quadratic stochastic operators defined on (m-1)-dimensional simplex, where l∈{0,1,...,m}. The l-Volterra operator is a Volterra operator if and only if l=m. We study the structure of the s

Introduction: Central pontine myelinolysis (CPM) is an acquired demyelinating lesion of the basis pontis that typically occurs after rapid correction of hyponatremia. There are only a few reported cases of patients without symptoms that have demonstr
