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...
Cascaded optical field enhancement in coupled plasmonic nanostructures has attracted significant attention because of field enhancement factors that dramatically exceed those observed in isolated nanostructures. While previous studies demonstrated the existence of cascaded enhancement, little work has been done to identify the requirements for achieving maximum field enhancement. Here, we inves...
Previous research on implicit focus on form (FonF) has shown that target forms are not always noticed by learners, suggesting that externally-created salience (by the teacher) does not necessarily guarantee learners’ internally-generated salience (Sharwood Smith, 1991, 1993). In an attempt to explore ways of promoting both types of salience, an input enhancement study was conducted in order to ...
The goal of this work is to resolve the present controversy in the value of the EDM enhancement factor in Tl. We have carried out several calculations by different high-precision methods, studied previously omitted corrections, as well as tested our methodology on other parity conserving quantities. We find the EDM enhancement factor of Tl to be equal to −573(20). This value is 20% larger than ...
