A Curie-Weiss model of self-organized criticality [PDF]

open access: yes, 2016
We try to design a simple model exhibiting self-organized criticality, which is amenable to a rigorous mathematical analysis. To this end, we modify the generalized Ising Curie-Weiss model by implementing an automatic control of the inverse temperature ...

Job Search With Legal and Illegal Workers: A Comparative Static Analysis

open access: yesEconomics and Business, 2020
This paper incorporates government immigration policy variables in a job search and match framework to examine its implication on labour market outcomes. The main assumption is that illegal workers can be penalized by receiving lower equilibrium wages or

The influence of selection in wild pheasant (Phasianus colchicus) breeding on reproduction and the involvement of the chemerin system

open access: yesPoultry Science, 2023
: Chemerin is a hormone produced mainly by adipose tissue and liver. We have recently shown that it is locally produced in the reproductive tract in hens, particularly at the magnum level, leading to its accumulation in the egg albumen.

Higher Order Derivatives in Costa's Entropy Power Inequality [PDF]

open access: yes, 2015
Let $X$ be an arbitrary continuous random variable and $Z$ be an independent Gaussian random variable with zero mean and unit variance. For $t~>~0$, Costa proved that $e^{2h(X+\sqrt{t}Z)}$ is concave in $t$, where the proof hinged on the first and second

Confocal Imaging of Transmembrane Voltage by SEER of di-8-ANEPPS [PDF]

open access: yes, 2013
Imaging, optical mapping, and optical multisite recording of transmembrane potential (Vm) are essential for studying excitable cells and systems. The naphthylstyryl voltage-sensitive dyes, including di-8-ANEPPS, shift both their fluorescence excitation ...

The Decay of Disease Association with Declining Linkage Disequilibrium: A Fine Mapping Theorem [PDF]

open access: yes, 2016
Several important and fundamental aspects of disease genetics models have yet to be described. One such property is the relationship of disease association statistics at a marker site closely linked to a disease causing site.
