A Spring–Beam System with Signorini’S Condition and the Normal Compliance Condition

On a p-Laplacian system and a generalization of the Landesman-Lazer type condition

This article shows the existence of weak solutions of a resonance problem for nonuniformly p-Laplacian system in a bounded domain in $mathbb{R}^N$‎. ‎Our arguments are based on the minimum principle and rely on a generalization of the Landesman-Lazer type condition‎.

A Hall Condition for Normal Hypergraphs

Rings with a setwise polynomial-like condition

Let $R$ be an infinite ring. Here we prove that if $0_R$ belongs to ${x_1x_2cdots x_n ;|; x_1,x_2,dots,x_nin X}$ for every infinite subset $X$ of $R$, then $R$ satisfies the polynomial identity $x^n=0$. Also we prove that if $0_R$ belongs to ${x_1x_2cdots x_n-x_{n+1} ;|; x_1,x_2,dots,x_n,x_{n+1}in X}$ for every infinite subset $X$ of $R$, then $x^n=x$ for all $xin R$.

Iniencephaly with Long Survival: A Rare Condition

Background & Importance: Iniencephaly is a rare cranio-cervical deformity. It belongs to neural tube defects. This disorder is characterized by a retroflexion of head, a very short neck, varying degrees of incomplete posterior closure of vertebrae and cervical and thoracic spinal synostosis. This malformation is associated with central nervous system and systemic malformations. Most o...

A Relaxation System Adapting to User's Condition

The purpose of this study is to build a relaxation system which can control a user’s body condition, changing the operation mode and intensity of the massage seat according to the user current condition. Heart rate is an index of human conditions which can be easily measured, and it has chaotic dynamics. In this paper, we show relations between the intensity of the massage operation and two ind...
