COVID-19 contact tracing is a preventive solution to slow the spread of virus. Several countries have implemented manual as well digital tracking using smartphone applications. A proximity-based system device BLE (Bluetooth Low Energy) technology focuses on and controlling virus in local communities. The devices consist signal sending (tag) receiving (scanner). Suppose factory. tag will be used...

This paper presents a method for measuring signal backscattering from an RFID tag and calculating tag radar cross-section (RCS), which depends on the chip input impedance. We present a derivation of a theoretical formula for RFID tag radar cross-section and an experimental RCS measurement method using a network analyzer connected to an antenna in an anechoic chamber where the tag is also locate...

Hepatic VLDL (very-low-density lipoprotein) assembly is a complex process that is largely regulated by the provision of lipid for apolipoprotein B assembly. Intracellular stored TAG (triacylglycerol) undergoes an initial lipolysis followed by re-esterification of the lipolytic products to form TAG prior to their incorporation into a VLDL particle. TGH (TAG hydrolase) is a lipase that hydrolyses...

The fatty acyl moieties incorporated into triacylglycerol (TAG) secreted by rat hepatocytes are derived from diacylglycerol (DAG) that is synthesized de novo through the phosphatidate pathway or derived from endogenous, cytosolic TAG after hydrolysis to DAG and re-esterification. We have used a dual-labeling technique (overnight labeling of cell TAG with [3H]oleate, followed by 3 h incubation w...

Ca2+-tolerant myocytes were isolated with endogenous triacylglycerol (TAG) stores prelabelled with [3H]palmitate and subsequently incubated for a 1h chase period with [14C]palmitate, 2% albumin and 5mM glucose. Measurements were then made of [14C]palmitate conversion into TAG and phospholipids, of loss of [3H]TAG, of glycerol release and of change in the total TAG content. Rates of de novo synt...

We investigate the accuracy of alternative part-of-speech tag models and their impact on parser performance. In addition to considering single-tag and multipletag per word input, tag selection models which draw on information available from the parser are applied. Results indicate that given a ‘good’ PoS tagger, parserbased tag selection models are unable to improve on the low tag error rates o...

Diacylglycerol acyltransferases (DGATs) play a key role in plant triacylglycerol (TAG) biosynthesis. Two type 1 and 2 DGATs from soybean were characterized for their functions in TAG biosynthesis and physiological roles. GmDGAT1A is highly expressed in seeds while GmDGAT2D is mainly expressed in flower tissues. They showed different expression patterns in response to biotic and abiotic stresses...

Protein purification is an essential procedure in fields such as biochemistry, molecular biology, and biophysics. Acquiring target proteins with high quality and purity is still difficult, although several tag systems have been established for protein purification. Affinity tag systems are excellent because they possess high affinity and specificity for acquiring the target proteins. Neverthele...

In this paper, an organic, fully recyclable and eco-friendly 20-bit inkjet-printed chipless RFID tag is presented. The operates in the near field implemented by means of chains resonant elements. characterization manufacturing process tag, printed with a few layers commercial organic ink on conventional paper substrate (DIN A4), are presented, functionality demonstrated reading it custom-design...
