Erythropoietin (EPO) exerts its effect on erythroid lineage cells through interaction with the EPO receptor (EPOR), so-called canonical pathway, and a complex consisting of EPOR common cytokine beta subunit (CD131) – non-canonical pathway for non-hematopoietic human animal body. realizes effects launch signaling cascade, which begins phosphorylation Janus kinase 2 (JAK2) then involvement phosphat...

This paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. To this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. The g...

It is proved that a discrete delta function introduced by P. Smereka [10] gives a second-order accurate quadrature rule for surface integrals using values on a regular background grid. The delta function is found using a technique of A. Mayo [7]. It can be expressed naturally using a level set function.

We show that, for some Cantor sets in R, the capacity γs associated to the s-dimensional Riesz kernel x/|x| is comparable to the capacity Ċ 2 3 (d−s), 3 2 from non linear potential theory. It is an open problem to show that, when s is positive and non integer, they are comparable for all compact sets in R. We also discuss other open questions in the area.

There are many benefits to having a highly accurate representation of the environment. Why, then, has evolution equipped us with a visual working memory (VWM) system that can represent only a handful of items with high accuracy? Here, we offer a normative explanation for this limitation by conceptualizing VWM as a system that balances between two conflicting goals: keeping memory errors small a...

We analyze the existence and singularity of solution to a reaction-diffusion equation, whose reaction term is represented by a Dirac delta function which depends on the solution itself. We prove that there exists a unique analytic solution with a logarithmic singularity at the origin.
