Allergic responses result from the activation of mast cells by the human high-affinity IgE receptor. IgE-mediated allergic reactions may develop to a variety of environmental compounds, but the initiation of a response requires the binding of IgE to its high-affinity receptor. We have solved the X-ray crystal structure of the antibody-binding domains of the human IgE receptor at 2.4 A resolutio...

In this paper, a new adaptive step-size discrete power control scheme is proposed, based on the review of practical power control schemes implemented in the IS-95, CDMA2000 and WCDMA wireless systems, and the power control algorithms proposed in literature. The transmit power is controlled in discrete power domain while using the idea of the most popular power control algorithm (e.g. DCPC) in p...

valuations on a topological space X are functions that map open sets to 0, 1, or one value in between. We deene a space of abstract valuations which for a continuous dcpo X is homeomorphic to the Plotkin power domain of X, and for a Hausdorr space X yields the Vietoris hyperspace of X. Thus we obtain a novel concrete representation of the Plotkin power domain. This representation is more simila...

objective: the study aimed to design and evaluate the content and face validity, and reliability of knowledge, attitude, and behavior questionnaire on preventive behaviors among vulnerable women concerning sexually transmitted diseases (stds). materials and methods: this cross-sectional study was carried out in two phases of an action research. in the first phase, to explain stds preventive dom...

Abstract A flag domain in ℝ 3 {\mathbb{R}^{3}} is a subset of the form { stretchy="false">( x , y t stretchy="false">) : < A ...

Objectives: Quality of life, when referring to an individual’s health, is called health-related quality of life. The purpose of this study is to assess self-perceived hearing loss related quality of life of adolescents with hearing loss and its relationship with sex, age sub-groups or school settings with domains of quality of life. Methods: A school based survey was conducted in Tehra...

In excitation-contraction (E-C) coupling, various types of activation signals, which are received presumably at the bulky cytoplasmic domain of the ryanodine receptor (RyR), are translated (or transduced) into the opening of the Ca2+ release channel located in the trans-membrane domain of the RyR. In order to elucidate the detailed mechanism of the signal transduction process, it is essential (...

the main goal of the development plans is to create livable environment, better quality of life and residential satisfaction. thus, the city managers desire to achieve this goal and plan a livable city for the people through the strategies, policies and intra-organizational programs, as well as making interaction with other influential administrations on the development of the city. as well as ...

the aim of this paper is to establish a fuzzy version of the dualitybetween domains and completely distributive lattices. all values aretaken in a fixed frame $l$. a definition of (strongly) completelydistributive $l$-ordered sets is introduced. the main result inthis paper is that the category of fuzzy domains is dually equivalentto the category of strongly completely distributive $l$-ordereds...
