RASSF enzymes act as key apoptosis activators and tumor suppressors, being downregulated in many human cancers, although their exact regulatory roles remain unknown. A key downstream event in the RASSF pathway is the regulation of MST kinases, which are main effectors of RASSF-induced apoptosis. The regulation of MST1/2 includes both homo- and heterodimerization, mediated by helical SARAH domai...
INTRODUCTION The authors present IR spectra (0.9–2.5 μm) and narrowband photometry (3.0–3.5 μm) for low-albedo asteroids Ceres, Pallas, and Bamberga. The authors compare the major mineral absorption features to those found in primary carbonaceous chondrite matrix material (CCMM) and secondary alteration products. The observed differences between spectral reflectances between the three C-type as...
The paper presents theoretical insights which might lead to further development of improved relay-based PID autotuners. The analysis is based on the first generation of autotuners, namely the widely used Åström-Hägglund relay-feedback tuner. The analysis is accompanied by illustrative examples. The performance of the autotuners is evaluated against a reference PID controller which is designed u...
با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی بهمنزلة راهبردی اساسی حل مسئلة تأمین غذا بهشمار میرود. سوی دیگر، وجود محدودیت زیرکشت پایینبودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول میتواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهمترین بیماریهای فوزاریوم است که، نقش پیشبینی این بیماری جلوگیری کاهش بهرهوری محصول، مدلهایی...
[1] We describe a method that retrieves surface photosynthetically active radiation (PAR) and its direct and diffuse components from the Surface and Atmospheric Radiation Budget (SARB) product of Clouds and the Earth’s Radiant Energy System (CERES). The shortwave spectrum in the SARB Edition 2 is calculated in 15 bands, 4 of which are used to develop the PAR, in conjunction with the look-up tab...
