peraxisome prolifrator-activated receptors (ppars) are a group of nuclear receptors comprising three isoforms termed alpha, beta/delta and gamma. ppars can modulate metabolic processes especially fatty acid (fa) metabolisms via exerting transcriptional control on activating genes involved in fuel utilization. thus, they can exert positive role in controlling chronic diseases such as diabetes. a...

Total Factor Productivity (TFP) is the portion of output not explained by the amount of inputs used in production. The following definition describes the measurement and importance of TFP for growth, fluctuations and development as well as likely future directions of research. Total Factor Productivity (TFP) is the portion of output not explained by the amount of inputs used in production. As s...

Behavioural type and effect systems regulate properties such as adherence to object and communication protocols, dynamic security policies, avoidance of race conditions, and many others. Typically, each system is based on some specific syntax of constraints, and is checked with an ad hoc solver. Instead, we advocate types refined with first-order logic formulas as a basis for behavioural type s...

We analyze access control mechanisms of the Enterprise Java Beans (EJB) architecture and define a configuration of the EJB protection system in a more precise and less ambiguous language than the EJB 3.0 standard. Using this configuration, we suggest an algorithm that formally specifies the semantics of authorization decisions in EJB. We analyze the level of support for the American National St...

Analysis constraints and its diversity in security access control model. Cardinality is a common constraint in access control model. An extended cardinality constraint access control model is established. According to actual demand, we describe the user-role, user-session, role-session cardinality constraints based on the RBAC model. The differences between static and dynamic cardinality constr...

Specifying, enforcing and evolving access control policies is essential to prevent security breaches and unavailability of resources. These access control design concerns impose requirements that allow only authorized users to access protected computer-based resources. Addressing these concerns in a design results in the spreading of access control functionality across several design modules. T...

RNA interference (RNAi), a naturally occurring phenomenon in eukaryotic organisms, is an extremely valuable tool that can be utilized in the laboratory for functional genomic studies. The ability to knockdown individual genes selectively via this reverse genetic technique has allowed many researchers to rapidly uncover the biological roles of numerous genes within many organisms, by evaluation ...

Role and Reference Grammar is a functional theory of language which allows an input text to be represented in terms of its logical structure. In order to go beyond the core grammar, the Lexical Constructional Model, which is grounded on the previous theoretical model, provides a fine-grained description of all aspects involved in meaning construction. This paper explores the integration of FunG...

Issues regarding the nature of the semantic relationships holding between a verb (or other predicating element) and its arguments have been the focus of much research and controversy since the mid-1960’s. Starting from Gruber (1965)’s notion of thematic relations and Fillmore (1968)’s concept of case roles, most contemporary theories of grammar assume some system of semantic predicate-argument ...

background: vasopressin type 2 receptor (v2r) plays an important role in the water reabsorption in the kidney collecting ducts. v2r is a g protein coupled receptor (gpcr) and the triplet of amino acids aspartate-arginine-histidine (drh) in this receptor might significantly influence its activity similar to other gpcr. however, the role of this motif has not been fully confirmed. therefore, the ...
