In this paper, an Ultra High Frequency (UHF) base band processor for a passive tag is presented. It proposes a Radio Frequency Identification (RFID) tag digital base band architecture which is compatible with the EPC C C2/ISO18000-6B protocol. Several design approaches such as clock gating technique, clock strobe design and clock management are used. In order to reduce the area Decimal Matrix C...

Flexible composition is an extension of TAG that has been used in a variety of TAG-analyses. In this paper, we present a dedicated study of the formal and linguistic properties of TAGs with flexible composition (TAG-FC). We start by presenting a survey of existing applications of flexible composition. In the main part of the paper, we discuss a formal definition of TAGFCs and give a proof of eq...

Several tag models with intriguing properties have been advanced recently. But currently there is little detailed understanding of the underlying processes. Specifically it is not know what (if any) are the necessary conditions for tag systems to produce high levels of cooperation. We identify, for the first time, what appears to be a necessary condition that previous tag models implicitly cont...

In this paper we introduce a tag separation method for better cardiac boundary segmentation and tag tracking. Our approach is based on two observations in the cardiac tagged MR images: 1) the tag patterns have a regular texture; 2) the cardiac images without tag patterns are piecewise smooth with sparse gradients. These observations motivate us to use two dictionaries, one based on the Discrete...

We designed a protein ladder (hereafter referred to as "Mega-tag") that contains 14 of the most commonly used epitope tags fused to molecular weight markers. The Mega-tag ladder can be simultaneously visualized when anti-tag antibodies are used to detect epitope-tagged recombinant proteins in Western blots. The logarithm of molecular weights and relative mobility of the Mega-tag protein ladder ...

recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. differed methods for protein purification are categorized, based on cast, quality, easy work and side effect of protein. in this article, we are investigating his his-tag protein pu...

We provide an account of the alignment of linguistic form and discourse function with respect to English tag questions, adopting as a formal framework Segmented Discourse Representation Theory. SDRT models the discourse function of utterances via their rhetorical connection to the antecedent discourse. We pay particular attention to the prosodic features of tag questions and their contribution ...
