Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2013 in the subject Computer Science - Miscellaneous, grade: 1, , course: ME computer science, language: English, abstract: This paper investigates how demand-side factors contribute to the Internet's 'Long Tail' phenomenon. It first models how a reduction in search costs will affect the concentration in product sales. Then, by analyzing data collected from a multi-channel retailing company, it provides empirical evidence that the Internet channel exhibits a significantly less concentrated sales distribution, when compared with traditional channels. The difference in the sales distribution is highly significant, even after controlling for consumer differences. Furthermore, the effect is particularly strong for individuals with more prior experience using the Internet channel. We find evidence that Internet purchases made by consumers with prior Internet experience are more skewed toward obscure products, compared with consumers who have no such experience. We observe the opposite outcome when comparing purchases by the same consumers through the catalog channel. If the relationships we uncover persist, the underlying trends in technology and search costs portend an ongoing shift in the distribution of product sales. Singular Value Decomposition (SVD), together with the Expectation-Maximization (EM) procedure, can be used to find a low-dimension model that maximizes the log likelihood of observed ratings in recommendation systems. However, the computational cost of this approach is a major concern, since each iteration of the EM algorithm requires a new SVD computation. We present a novel algorithm that incorporates SVD approximation into the EM procedure to reduce the overall computational cost while maintaining accurate predictions. Furthermore, we propose a new framework for collaborating filtering in distributed recommendation systems that allows users to maintain their own rating profiles for privacy. We conduct offline and online tests of our ranking algorithm. We use Yahoo! Search queries that resulted in a click on a Yahoo! Movies or Internet Movie Database (IMDB) movie URL. Our online test involved 44 Yahoo! Employees providing subjective assessments of results quality. In both tests, our ranking methods show significantly better recall and quality than IMDB search and Yahoo! Movies current search. Reduced rank approximation of matrices has hitherto been possible only by un-weighted least squares. This paper presents iterative techniques for obtaining such approximations when weights are introduced.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Doctoral Thesis / Dissertation from the year 2014 in the subject Chemistry - Bio-chemistry, , language: English, abstract: Oxidative stress, excess generation of Reactive Oxygen Species (ROS), is a common event in many pathological conditions including cancer. The generation of reactive oxygen species (ROS) is an inevitable aspect of life under aerobic conditions. ROS are continuously produced as byproducts of certain metabolic pathways and also by some specific systems under fine cellular control. At the same time, ROS are degraded via several specific and nonspecific mechanisms. These two processes are usually under tight cellular control and very low (<10-8 M) steady-state levels are maintained. However, under some special conditions, the balance between ROS production and elimination is disturbed and leading to generation of super oxides (O2-), hydroxyl radical (OH-) and hydrogen peroxide (H2O2).H2O2, a common intermediate of various enzymatic and non-enzymatic reactions including electron transport chain, peroxisomal oxidases, flavoproteins as well as D-amino acid oxidases, L-hydroxy acid oxidases and fatty acyl oxidases. In endoplasmic reticulum, cytochrome P-450, P-450 reductase and cytochrome b-5 reductase generate superoxide anion and hydrogen peroxide during their catalytic cycles. The catalytic cycle of xanthine oxidase has emerged as an important source of O2 - and H2O2. During phagocytosis, the phagocytic cells such as neutrophils generate O2- and H2O2 by NADPH oxidase. Inflammation is also one of the major sources of ROS. Spontaneous dismutation of O2- at neutral pH or dismutation by superoxide dismutase also results in H2O2 production. Substantial evidence has indicated that H2O2 play a key role in wide range of diseases including CNS , autoimmune, cardiac, alveolar and hepatic disorders. The pathological role of H2O2 is well established in many acute and chronic disorders such as ischemia, atherosclerosis, diabetes, aging, immuno suppression and neuro degeneration.H2O2 is an important metabolite produced in cells during metabolic reactions, plays an important role in cell death (or) apoptosis. Accumulating data suggest that an increase in the cellular concentrations of H2O2 associated with DNA damage and mutations which leads to the prevalence of various disorders. H2O2 induced DNAf damage seems to be mediated by OH.- generated from H2O2. Several studies have also demonstrated that increased levels of H2O2 can induce cell death.
