The lifespan of Caenorhabditis elegans is determined by various genetic and environmental factors. In this paper, spr-3, a C. elegans homologous gene of the mammalian neural restrictive silencing factor (NRSF/REST), is reported to be an important gene regulating lifespan of C. elegans. A deletion mutation of spr-3, spr-3(ok2525), or RNAi inhibition of spr-3 expression led to the short lifespan ...

Self-piercing riveting (SPR) is a high-speed mechanical fastening technique which is suitable for point-joining advanced lightweight sheet materials that are dissimilar, coated, and hard to weld. Major advances have been made in recent years in SPR technique. Latest literature relating to finite element analysis (FEA) of SPR joints is reviewed in this paper. The recent development in FEA of SPR...

Surface plasmon resonance (SPR) biosensors are optical sensors exploiting special electromagnetic waves-surface plasmon-polaritons-to probe interactions between an analyte in solution and a biomolecular recognition element immobilized on the SPR sensor surface. Major application areas include detection of biological analytes and analysis of biomolecular interactions where SPR biosensors provide...

Surfaceplasmonresonance (SPR) methods are surface-sensitive spectroscopic techniques that can be used to characterize a variety of ultrathin organic monolayers and multilayers at gold, silver, and copper surfaces. For example, SPR measurements have been used to study Langmuir-Blodgett films {1-3), selfassembled organic monolayers (4,5), specifically and nonspecifically adsorbed biopolymers (inc...

This work develops a highly sensitive immunoassay sensor for use in graphene oxide sheet (GOS)-based surface plasmon resonance (SPR) chips. This sensing film, which is formed by chemically modifying a GOS surface, has covalent bonds that strongly interact with the bovine serum albumin (BSA), explaining why it has a higher sensitivity. This GOS film-based SPR chip has a BSA concentration detecti...

This paper examines the relationship between Hofstede’s national culture indices (IDV, PSI, MAS, and UAI), economic wealth (GNI), and software piracy rates (SPR). Although a number of studies have already examined this relationship, the contribution of this paper is two-fold. First, we will examine not only the relationship to SPR, but also the relationship to declines in SPR. The average natio...

Surface plasmon resonance (SPR) is a label-free, highly-sensitive, and real-time sensing technique. Conventional SPR sensors, which involve a planar thin gold film, have been widely exploited in biosensing; various miniaturized formats have been devised for portability purposes. Another type of SPR sensor which utilizes localized SPR (LSPR), is based on metal nanostructures with surface plasmon...

Surface plasmon resonance (SPR) sensor, an optical sensor exploiting special electromagnetic waves-surface plasmon polaritons to probe interactions between an analyte in solution and a molecular recognition element immobilized on the SPR sensor surface, has been widely used in various realms, such as investigating biomolecular interactions and binding properties, detection of biological and che...

Class specific mortality in 17th and 18th Century Vienna shows a cyclical pattern which is related to grain price cycles in the 5-10 years range. This relationship is not stable over time. Applying spectral analysis based on time-varying VARs, it can be shown that at the beginning of the observation period, comovement of grain prices and mortality is considerably high in areas populated by lowe...
