We present SMARTS consortium optical/IR light curves of SN 2006aj associated with GRB 060218. We find that this event is broadly similar to two previously observed events SN 1998bw/GRB 980425 and SN 2003lw/GRB 031203. In particular, all of these events are greatly under-luminous in gamma-rays compared to typical long-duration GRBs. We find that the observation by Swift of even one such event im...

The intuitive way of chemists to communicate molecules is via two-dimensional structure diagrams. The straightforward visual representations are mostly preferred to the often complicated systematic chemical names. For chemical patterns, however, no comparable visualization standards have evolved so far. Chemical patterns denoting descriptions of chemical features are needed whenever a set of mo...

pomegranate is an importantly popular fruit crop with iran the main center of its diversity throghout the world. the richest pomegranate genetic resources believed to exist in iran. the present investigation was carried out to study the genetic diversity of 15 genotypes of pomegranate in tarume zanjan making use of rapd markers. genomic dna was extracted from the plant,s leaf, and tested for th...

A laboratory study was conducted to determine how sensory changes in elderly people affect subjective assessments of floor slipperiness, and associated friction demand characteristics and slip distance. To relate these parameters to actual slip and fall incidents, 30 subjects from two age groups (young and elderly) walked around a circular track on the slippery and non-slippery floor surfaces, ...

The ability to update the program code installed on wireless sensor nodes plays an import role in the highly dynamic environments sensor networks are often deployed in. Such code update mechanisms should support flexible reconfiguration and adaptation of the sensor nodes but should also operate in an energy and time efficient manner. In this paper, we present FlexCup, a flexible code update mec...

Food security is a key component of state security, and every country, especially some great powers in the world, has been paying more attention to national food security and its security system. This paper aimed at applying grey model to food security assessment in the province scale from statistical data and developing a prototype of food security assessment system in Liaoning Province. First...

We analyze the expected delay for infinite precision arithmetic codes, and suggest a practical implementation that closely approximates the idealized infinite precision model.
