for the WA97 collaboration) The WA97 experiment studies the production of strange and multistrange particles in Pb{Pb and p{Pb collisions at 158 GeV/c per nucleon. Recent results on and production ratios and transverse mass distributions are reported and compared with those obtained by WA85 and WA94 experiments. A signiicant enhancement of the // ratio has been observed when going from nucleon-...

Histogram equalization (HE) is one of the common methods used for image enhancement. Histogram equalization has proved to be a simple and effective image contrast enhancement technique. The major difference among the methods in this family is the criteria used to divide the input histogram. For preserving the input brightness of the image, there is a segment to avoid the generation of non-exist...

Second language acquisition research since the 90s has emphasized the importance of supporting awareness of language categories and forms, and input enhancement techniques have been proposed to make target language features more salient for the learner. We present an NLP architecture and webbased implementation providing automatic visual input enhancement for web pages. Learners freely choose t...

Gap-plasmon-enhanced gold nanoparticle photoluminescence is studied experimentally at the single-particle level. The photoluminescence spectra of gold nanoparticles on an Al2O3-coated gold film under both 532 and 633 nm excitation show a clear peak near the measured gap-plasmon resonance wavelength. Comparing the collected emission spectrum with that from a gold reference film under 633 nm exci...

for three different back surface recombination velocities (BSRV). The calculations reveal that the carrier lifetime limits the screen-printed (SP) EFG Si cell efficiency for lifetimes below -30 /-Is. For a 300 /-1m thick device, the carrier lifetime should be greater than 30 /-Is to realize the full benefit of a low BSRV. Therefore, lifetime enhancement is essential for achieving high efficienc...

Further exploration of confinement trends in the evolving International Stellarator Confinement Database is reported. The impact of configurations on confinement is confirmed and the performance close to operational limits discussed. Model comparison techniques allow for tests of physical models against data. Correlations of configuration-describing parameters against an empirical confinement e...

A plausible model is proposed for the enhancement of the abundance of molecular species in bipolar outflow sources. In this model, levels of HCO+ enhancement are considered based on previous chemical calculations, which are assumed to result from shock-induced desorption and photoprocessing of dust grain ice mantles in the boundary layer between the outflow jet and the surrounding envelope. A r...

Schema mapping and data mapping have been two topics widely studied in traditional database related communities. Recently, with the rising interest in the semantical web, the tasks of integrating heterogeneous information sources, both in a schema and a data instance level, are becoming of more practical importance. Current efforts at resolving these two mapping tasks, namely, schema mapping an...

Two decades since calls for stream restoration projects to be scientifically assessed, most projects are still unevaluated, and conducted evaluations yield ambiguous results. Even after these decades of investigation, do we know how to define and measure success? We systematically reviewed 26 studies of stream restoration projects that used macroinvertebrate indicators to assess the success of ...

We have developed a fully-depleted SOI-MOSFET model HiSIM-SOI for circuit simulation by solving the potential distribution along all three important SOI-surfaces selfconsistently. Besides comparison to measured I-V data, the model is verified with 1/f noise analysis, sensitive to the carrier concentration and distribution along the channel. The carrier concentration increase, due to confinement...
