Formal accounts of contextual reasoning are of great importance for the development of sophisticated Artificial Intelligence theory and applications. This thesis’ contribution to the theory of contextual reasoning is twofold. First, it delineates the computational complexity of contextual reasoning. A first insight is obtained by translating contextual reasoning into a rather simple form of rea...

The discovery of Bd − Bd oscillations twenty years ago by the ARGUS collaboration marked a watershed event. It persuaded a significant part of the HEP community that the large time dependent CP asymmetries predicted for some Bd decays might be within the reach of specially designed experiments. This opened the successful era of the B factories, which has a great future still ahead. After sketch...

Background: Plant growth regulators gave entry into animals and human cells through diet. Gibberellic acid (GA3) is an extensively prevalent plant growth regulator due to its use in agriculture. Therefore current study was designed to investigate the effect of GA3 compound on sperm DNA integrity, nuclear maturity and motility. Materials and Methods: To follow-up current study 12 mature male s r...

Objective(s): To analyze the potential influences of propofol on the oxidative stress of H2O2-induced human esophageal squamous cell carcinoma (ESCC) Eca109 cell through mediating the Wnt/β-catenin signaling pathway.Materials and Methods: Eca109 cells were classified into 5 groups: Control group, H2O2 group, Propofol + H2O2 group, Dkk1 (Dickkopf-1, Wnt/β-catenin pathway antagonist) + H2O2 group...

multiple sclerosis (ms) and migraine are two common neurological disorders affecting women more than men. sleep quality impairment has been reported in both diseases. the goal of this study was to compare sleep quality and depression between women with ms and migraine. seventy women with migraine and 75 women with ms were enrolled in this study. participants were asked to fill-out valid and rel...

In this paper, a two-phase protocol for relay-assisted spectrum sharing in cognitive relay network is proposed. The primary system comprises a transmitter-receiver pair (PT-PR) and a decode-and-forward relay (Relay), while the secondary system comprises a transmitter-receiver pair (ST-SR). In the proposed protocol, the Relay assists the transmissions of the primary users as well as the secondar...

In this study, we report here a rare case of polycythemia and cRCC in the same patient, which may be helpful in understanding clinical features and molecular mechanisms underlying VHL-mutation-associated cRCC and polycythemia induced by germline mutation of HIF2A. Firstly, we identified a rare but well studied germline mutation resulting in polycythemia in HIF2A (c.1609G>A, p.Gly537Trp) in the ...

Caricature is an art form that expresses subjects in abstract, simple and exaggerated view. While many caricatures are 2D images, this paper presents an algorithm for creating expressive 3D caricatures from 2D caricature images with a minimum of user interaction. The key idea of our approach is to introduce an intrinsic deformation representation that has a capacity of extrapolation enabling us...

This paper presents an effective improved artificial potential field-based regression search (improved APF-based RS) method that can obtain a better and shorter path efficiently without local minima and oscillations in an environment including known, partially known or unknown, static, and dynamic environments. We redefine potential functions to eliminate oscillations and local minima problems,...
