Since communications between tag and reader in RFID system are by radio, anyone can access the tag and obtain its any information. And a tag always replies with the same ID so that it is hard to distinguish between a real and a fake tag. Thus, there are many security problems in today’s RFID System. Firstly, unauthorized reader can easily read the ID information of any Tag. Secondly, Adversary ...

This paper extends the idea of switching T-S fuzzy systems with linear consequent parts to nonlinear ones. Each nonlinear subsystem is exactly represented by a T-S fuzzy system with Lure’ type consequent parts, which allows to model and control wider classes of switching systems and also reduce the computation burden of control synthesis. With the use of a switching fuzzy Lyapunov function, the...

This paper proposes a hybrid switching technique for a domestic PV system with AC-module architecture. In this PV system, independent control of PV modules, which are directly connected to DC terminals of a single-phase cascaded multilevel inverter, makes module-level MPPT possible to extract maximum available solar energy, especially in partial shading conditions. As one of the main contributi...

“Code-Switching”, an important issue in the field of both language classroom and sociolinguistics, has been under consideration in investigations related to bilingual and multilingual societies. First proposed by Haugen (1956) and later developed byGrosjean (1982), the termcode-switching refers to language alternation during communication. Although code-switching is unavoidable in bilingual and...

BACKGROUND The human polyomavirus, JC virus (JCV) produces five tumor proteins encoded by transcripts alternatively spliced from one precursor messenger RNA. Significant attention has been given to replication and transforming activities of JCV's large tumor antigen (TAg) and three T' proteins, but little is known about small tumor antigen (tAg) functions. Amino-terminal sequences of tAg overla...

background: parathyroid hormone is an 84-amino acid peptide secreted by the parathyroid glands. its physiological role is maintenance of normal serum calcium level and bone remodeling. biological activity of this hormone is related to n-terminal 1-34 amino acids. the recombinant form of hormone (1-34) has been approved for treatment of osteoporosis from 2002. in this study, a novel fusion partn...

Electrochemical aptamer-based (E-AB) sensors have emerged as a promising and versatile new biosensor platform. Combining the generality and specificity of aptamer-ligand interactions with the selectivity and convenience of electrochemical readouts, this approach affords the detection of a wide variety of targets directly in complex, contaminant-ridden samples, such as whole blood, foodstuffs an...
