The test cases are generated manually as well as automatically to test software product. Manual test case generation require more time and cost than automatic test case generation. Automated generated test cases decrease the time and cost of testing process. Nowadays software companies are turning towards automated test case generation. After the generation of test cases, there is need to optim...

IL-15 and IL-15Ralpha are required for generation of memory-phenotype CD8 T cells in unimmunized mice. However, the role of IL-15 in primary expansion and generation of Ag-specific memory CD8 T cells in vivo has not been investigated. We characterized the CD8 T cell response against vesicular stomatitis virus (VSV) in IL-15(-/-) and IL-15Ralpha(-/-) mice. Surprisingly, IL-15 was required for pr...

در عصری زندگی می کنیم که آنرا عصر اطلاعات نامیده اند و بی شک سنجش از دور ‏‎(rs)‎‏ بعنوان ابزاری قوی در جمع آوری داده ها از جایگاه ویژه برخوردار می باشد. استفاده صحیح از داده های سنجش از دور جهت حل مشکلات و معضلات شهری یکی از مهمترین دغدغه های بسیاری از مدیران و برنامه ریزان شهری می باشد. با توجه به اینکه سیستم اطلاعات جغرافیایی ‏‎(gis)‎‏ بعنوان ابزاری قوی در نگهداری، تحلیل و مدیریت داده های زمی...

We use quasi-experimental variation due to the introduction of fracking to estimate the impact of a decrease in natural gas prices on marginal air pollution emissions from electricity producers. We find natural gas generation has displaced coal fired generation as the marginal fuel source significantly changing the marginal emissions profile. The impact of cheap natural gas varies across U.S. r...

Distributed power generation-electricity generation that is produced by many small stationary power generators distributed throughout an urban air basin-has the potential to supply a significant portion of electricity in future years. As a result, distributed generation may lead to increased pollutant emissions within an urban air basin, which could adversely affect air quality. However, the us...

Telomere shortening can lead to chromosome instability, replicative senescence, and apoptosis in both somatic and male germ cells. To study roles for mammalian telomeres in homologous pairing and recombination, we characterized effects of telomere shortening on spermatogenesis and oogenesis in late-generation telomerase-deficient mice. We show that shortened telomeres of late-generation telomer...

What knowledge do subjects acquire in sequence-learning experiments? How can they express that knowledge? In two sequence-learning experiments, we studied the acquisition of knowledge of complex probabilistic sequences. Using a novel experimental paradigm, we were able to compare reaction time and generation measures of sequence knowledge online. Hidden Markov models were introduced as a novel ...

A novel synthesis is presented of a fourfold ethynyl-substituted perylene diimide dye 4, which acts as a core molecule for the buildup of polyphenylene dendrimers. Around the luminescent core 4, a first-generation (5), a second-generation (6), and a third-generation (7) polyphenylene dendritic environment consisting of pentaphenylbenzene building blocks are constructed. The dendrimers 5 and 6 a...

In the Japanese pear pathotype of Alternaria alternata, H2O2 is generated solely from penetration pegs and not from other portions of subcuticular hyphae within the pectin layers of host leaves. A close association between H2O2 generation and fungal aggressiveness is expected because the pegs are important for fungal penetration into the host epidermis. To determine the potential role of reacti...
