Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...

Today we examine the zig-zag product introduced by Reingold, Vadhan, and Wigderson [2] and Capalbo, Reingold, Vadhan, and Wigderson [1]. The product leads to a remarkable constructioon of expander graphs needed in the Spiser-Spielman code. In addition, their works introduce a probabilistic viewpoint of expansion. In previous literature, the spectral techniques are used to analyze the expansion ...

active video gaming and other energy-balance related behaviours in adolescents: a 24-hour recall diary study. Abstract Background

We propose a string realization of the AdS4 brane in AdS5 that is known to localize gravity. Our theory is M D5 branes in the near horizon geometry of N D3 branes, where M and N are appropriately tuned.
