Depresyon bir stresle veya hayvan modellerinde oldu ğu gibi öğrenilmiş çaresizlikle meydana gelir ve sürer. Stres beyinde norepinefrin (NE) sekresyonunu artt ırır, buna ikincil ola,* beta adreneıjik reseptörlerde down regülasyon olur. Strese ikincil, NE sekresyonunun art ışı ayn ı zamanda NE depresyonuna da yol açar. Aksiyon potansiyeli sinaptik aralığa ulaştığında hücre içine kalsiyum iyonları...

The Laplacian operator is invariant under rigid motions: For any function u on R and for any rigid motion T W R ! R, .u ı T / D . u/ ı T: T is called a rigid motion if T x Ox C b for some n n orthogonal matrix O and some vector b 2 R. It is clear that a linear second-order partial differential operator Lu WD aij .x/uij C bi .x/ui C c.x/u is invariant under rigid motion, i.e., L.u ı T / D .Lu/ ı...

When agents first become active investors in financial markets, they are relatively inexperienced. Much of the literature focuses on the incentives of presumably sophisticated informed agents to produce information, and not on the na¨ıve agents. However , unsophisticated agents are important aspects of financial markets and worth analyzing further. In this paper, we provide a theoretical perspe...

We study a special sort of 2-dimensional extended Topological Quantum Field Theories (TQFTs). These are defined on open-closed cobordisms by which we mean smooth compact oriented 2-manifolds with corners that have a particular global structure in order to model the smooth topology of open and closed string worldsheets. We show that the category of open-closed TQFTs is equivalent to the category...

Let ı : T p → Rp+2, p ≥ 1, be an embedded p-torus into the Euclidean space Rp+2, and Eı be the subgroup of MT p , the mapping class group of T , whose elements extend over Rp+2 as self-diffeomorphisms. We show that for any unknotted embedding ı : T p → Rp+2, Eı is a subgroup of MT p of index 2−1. We also provide a matrix characterization. This applies to showing that for any expanding map φ : T...

The package a˚ı T alc has been developed for the automated calculation of radiative corrections to two-fermion production at e + e − colliders.

Color image segmentation is a crucial step in many computer vision and pattern recognition applications. This article introduces an adaptive and unsupervised clustering approach based on Vorono¨ı regions, which can be applied to solve the color image segmentation problem. The proposed method performs region splitting and merging within Vorono¨ı regions of the Dirich-let Tessellated image (also ...
