Joint estimation of RFID-tag position and gain is proposed for RFID-assisted surgery support system. Although various RFID-tag positioning schemes have been proposed, gain variations in RFID-tag could affect the accuracy in the positioning. This paper uses a non-linear optimization method to estimate the gain and position of RFID-tag simultaneously. Computer simulation result shows that the pro...

Tags associated with social images are valuable information source for superior image search and retrieval experiences. Although various heuristics are valuable to boost tag-based search for images, there is a lack of general framework to study the impact of these heuristics. Specifically, the task of ranking images matching a given tag query based on their associated tags in descending order o...

Due to the increasing popularity of tagging, it is important to overcome challenges resulting from the free nature of tagging, such as the use of synonyms, homonyms, syntactic variations, etc. The Semantic Tag Clustering Search (STCS) framework deals with these challenges by detecting syntactic variations of tags and by clustering semantically related tags. We evaluate our framework using Flick...

The dietary triacylglycerol (TAG) gets absorbed and accumulated in the body through monoacylglycerol (MAG) pathway, which plays a major role obesity related disorders. main enzyme of this acyltransferase 2 (MGAT2), is considered as potential target for developing antiobesity compounds. Hence, there need vitro cell-based assays screening leads MGAT2 inhibitors. Because synthetic inhibitor’s side...

Two billion people are latently infected with Mycobacterium tuberculosis (Mtb). Mtb-infected macrophages are likely to be sequestered inside the hypoxic environments of the granuloma and differentiate into lipid-loaded macrophages that contain triacylglycerol (TAG)-filled lipid droplets which may provide a fatty acid-rich host environment for Mtb. We report here that human peripheral blood mono...

Triacylglycerol (TAG) lipases are required for mobilization of TAG stored in lipid particles. Recently, Tgl3p was identified as a major TAG lipase of the yeast Saccharomyces cerevisiae (Athenstaedt, K., and Daum, G. (2003) J. Biol. Chem. 278, 23317-23323). Here, we report the identification of Tgl4p and Tgl5p as additional TAG lipases of the yeast. Both polypeptides, encoded by open reading fra...

The authors recently noticed that the published amino acid sequence of the protein C epitope tag component of the CNAP tag was incorrect. The published amino acid sequence of the protein C (PC) epitope tag was EDQVDPIDGK and should have been EDQVDPRLIDGK. Thus, the correct amino acid sequence of the CNAP tag employed is: MEDQVDPRLIDGK-GGAGG-HHHHHHHHHH (protein C [PC] epitope tag is underlined, ...

Signcryption tag-KEM (key encapsulation mechanism with tag) allows the sender to encapsulate a symmetric key along with a tag so that the receiver can authenticate the sender, the key and the tag. In this paper, we introduce the notion of signcryption tag-KEM to the self-certified setting and ring signcryption, and construct a tag-KEM for self-certified ring signcryption, which only takes one p...

This paper is to investigate some general features of social tagging and folksonomies along with their advantages and disadvantages, and to present an overview of a tag ontology that can be used to represent tagging data at a semantic level using Semantic Web technologies. Several tag ontologies have been developed with a specific purpose and used in various websites. However, in order to repre...

Triacylglycerol (TAG) analysis and quantification are commonly performed by first obtaining a purified TAG fraction from a total neutral lipid extract using thinlayer chromatography (TLC), and then analyzing the fatty acid composition of the purified TAG fraction by gas chromatography (GC). This process is time-consuming, labor intensive and is not suitable for analysis of small sample sizes or...
