Let $\mathcal{C}$ be a $(d+2)$-angulated category. In this note, we show that if is locally finite, then has Auslander-Reiten $(d+2)$-angles. This extends result of Xiao and Zhu for triangulated categories.
The two-dimensional (2D) version of ferromagnet XXZ spin chain with DzyaloshinskyMoriya (DM) interaction, recently introduced by F. Kenmogne and coworkers is reexplored. Firstly using the Dyson-Maleev transformation, 2-D discrete nonlinear Schrödinger (DNLS) equation, governing quantum states behaviors found. Next semidiscrete multiple-scale method, DNLS equation reduced to 2D extended (ENLS) w...
Lympho-stromal interactions in the thymus crucially de- termine the fate of developing T cells. Epithelial cells, inter- digitating reticular cells, macrophages and fibroblasts all play a role in the shaping of the T cell repertoire. Recently published evidence shows that lympho-stromal interaction acts bi-directional. Developing T cell themselves, at different stages of differentiation, contro...
This document is about the “UWB co-existence analysis” to be published as an Ultrawaves deliverable D2.2. The document covers the co-existence studies between ultra wideband and other radio systems. If UWB systems will be adopted in a common use globally, or only in Europe, an inevitable consequence is that the UWB co-existence issues will have more and more significant role in the near future ...
The invention of the digital camera is attributed to Eastman Kodak engineer Steven Sasson in 1975 [1]. Sasson’s device recorded 0.01-megapixel black-and-white pictures to cassette tapes. The first digital photograph required 23 seconds to generate and needed a television set to display [2]. Today, digital cameras recording greater than 10-megapixel color photos to Secure Digital (SD) cards with...
