An approach to develop room temperature detectors is to use transitions between the light/heavy hole bands and the split-off hole band to produce enhanced response at high temperature. Results are presented on a theoretical model to predict the response in these split-off detectors. The model calculates the dark and illuminated currents from the photoabsorption, carrier escape, and transport, e...

Western scholars implicitly assume that the correlates of fear of crime discovered in the extant literature are also applicable to populations of different culture and ethnic backgrounds. The current study investigates whether such an assumption is valid, drawing on survey data of Chinese immigrants in Houston. Among other findings, this study reveals that the effect of age on fear of crime is ...

In a previous paper (Buchbinder and Phelps, 1941) a method was described whereby the survival rates of streptococci in simulated room environments may be determined with the use of a petri plate technic. It was found by this method that the death rates of streptococci in the dark under these simulated room conditions were geometric and that the median survival time (m.s.t.), of the three strain...

One challenge in facing the application of biomedical Raman spectroscopy is that the Raman signal is acquired in a dark operation room. It is inconvenient for both the operator and the patient because it is difficult for the operator to accurately and precisely locate the target in the dark environment, and the patient feels uncomfortable in such a setting. In this note, we propose a method to ...

to breaking dormancy as well as the effect of light, temperature, salinity and drought stress on germination of cutleaf mignonette seeds, experiments were conducted at the research laboratory of birjand faculty of agriculture in 2009. immersion in sulfuric acid (96%) for 30 seconds under continuous dark regime resulted in the highest germinability (73%) and the lowest germination (8%). was obse...

The current acceleration of the Universe is one of the most puzzling issues in theoretical physics nowadays. We are far from giving an answer in this letter to the question of its nature. Yet, with the observations we have at hand, we analyse the different patterns that the gravitational potential can show in the future. Surprisingly, gravity not only can get weaker in the near future, it can e...

a study of the Literature of Inoculation for Rabies and Hydrophobia. Now evidence may be collected from the student in the workshop, or from gossip in the market-place. Our author has chosen the latter source. The literature studied and quoted is that ordinarily found on the table of the reading-room of a London Club. We have quotations from The Times and The Field?these have some weight; and w...

: optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (pr) crystal are investigated. each crystal can be supported the spatial soliton, and at least one must be photovoltaic. the two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
