A study has been made of the effect of sudden intense flashes of ultraviolet light, acting on a wide variety of cells and tissues, with special reference to stimulation. The flashes are obtained by a high voltage condenser discharge through a quartz mercury vapor sterilamp, using the method of Rentschler. The lethal effect of a single such discharge is widespread among unicellular organisms. Me...

In this paper, a semi-supervised modeling framework that combines feature-based (x) data and graph-based (G) data for classification/regression of the response Y is presented. In this semi-supervised setting, Y is observed for a subset of the observations (labeled) and missing for the remainder (unlabeled). The Propagated Scoring algorithm proposed for fitting this model is a semi-supervised fi...

The recent outbreaks of chikungunya (CHIK) were due to an East-Central-South African genotype harbouring a substitution from an Alanine (E1-226A) to a Valine (E1-226V) at the position 226 in the E1 gene. The new variant E1-226V is very efficiently transmitted by an unusual mosquito vector, Aedes albopictus. We found that (i) Ae. albopictus females ensure a high replication rate of E1-226V up to...

Copy number variation (CNV) has been revealed as a significant contributor to the genetic variation in humans. Although CNV has been reported in several model animal and plant species, the presence of CNV and its biological impact in polyploid species has not yet been documented. We conducted a fluorescence in situ hybridization (FISH)-based CNV survey in potato, a vegetatively propagated autot...
