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...

Pressure driven liquid flow through rectangular cross-section microchannels is investigated experimentally. Polydimethylsiloxane microchannels are fabricated using soft lithography. Pressure drop data are used to characterize the friction factor over a range of aspect ratios from 0.13 to 0.76 and Reynolds number from 1 to 35 with distilled water as working fluid. Results are compared with the g...

We study theoretically the light scattering from metal wires of arbitrary cross section, with emphasis on the occurrence of plasmon resonances. We make use of the rigorous formulation of the Green's theorem surface integral equations of the electromagnetic wave scattering, written for an arbitrary number of scatterers described in parametric form. We have investigated the scattering cross secti...

Synesthesia is a phenomenon in which an experience in one domain is accompanied by an involuntary secondary experience in another, unrelated domain; in classical synesthesia, these associations are arbitrary and idiosyncratic. Cross-modal correspondences refer to universal associations between seemingly unrelated sensory features, e.g., auditory pitch and visual size. Some argue that these phen...

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.

Structure-activity relationship (SAR) is one of the foundational principles of biomolecular activity and states that similar molecules have similar biological activity. This work is focused on the utilization of enzymatic reactions in order to augment ligands with small apolar substituents. These modified molecules will then be employed for establishing the SAR of a ligand series. For this purp...

This paper presents a new approach to incremental code clone detection that is based on a special clone representation model. The algorithm detects parameterized clones with parameters of arbitrary size. It can be used for cross-system and cross-revision clone detection.
