Abstract
We have developed an approach for passive radio-frequency identification (RFID)-based sensing that converts ubiquitous passive 13.56 MHz RFID tags into inductively coupled sensors. We combine several measured parameters from the resonant sensor antenna with multivariate data analysis and deliver uni...

Abstract
We measured achievement with year-long teacher assessments as well as tests. Raw achievement shows moderate heritability (about 50%) and modest shared environmental influences (25%). Unexpectedly, we show that for indices of the added value of school, genetic influences remain moderate (around 50%),...

Abstract
We have isolated endophytic fungi from Indian yew tree, Taxus baccata and then screened for taxol production. Out of the forty fungal cultures screened, one fungus Gliocladium sp. was found to produce taxol and 10DAB III (10 Deacetyl baccatin III). These compounds were purified by TLC, HPLC and char...
