We consider an unconstrained minimization reformulation of the generalized complementarity problem GCP(f, g) when the underlying functions f and g are H-differentiable. We describe H-differentials of some GCP functions based on the min function and the penalized Fischer-Burmeister function, and their merit functions. Under appropriate semimonotone (E0), strictly semimonotone (E) regularity-cond...
The Generation Challenge programme (GCP) is a global crop research consortium directed toward crop improvement through the application of comparative biology and genetic resources characterization to plant breeding. A key consortium research activity is the development of a GCP crop bioinformatics platform to support GCP research. This platform includes the following: (i) shared, public platfor...
سکوهای پرنده بدون سرنشین به‌عنوان یکی از منابع تهیه اطلاعات در این سیستم‌های فرماندهی و کنترل، علاوه بر قابلیت تهیه محصولات سه‌بعدی دقیق، مزایای متعددی ازجمله کاهش زمان، هزینه‌ها و تجهیزات خاص و نیاز کمتر به افراد متخصص را نسبت به سایر روش‌ها دارا هستند. در این مقاله به ارزیابی قابلیت‌های نوین سکوهای پرنده بدون سرنشین، آنالیز و تلفیق اطلاعات این سنجنده‌های قابل‌نصب بر این وسایل و استفاده از این...
آزمایش به منظور تعیین دوره بحرانی خسارت علف های هرز در بادام زمینی در قالب طرح بلوک های کامل تصادفی در سال 1391 با سه تکرار اجرا شد. تیمارها به دو نوع تداخل و عاری از علف های هرز در دوره های 15، 30، 45، 60 و 75 روز پس از کاشت بادام زمینی اعمال شدند. علاوه بر این دو شاهد تمام فصل تداخل و عاری از علف هرز طی فصل رشد نیز در نظر گرفته شد. عملکرد دانه به طور معنی داری تحت تاثیر تیمارهای کنترل و تداخل...
Glycogen is a glucose polymer that contains minor amounts of covalently attached phosphate. Hyperphosphorylation is deleterious to glycogen structure and can lead to Lafora disease. Recently, it was demonstrated that glycogen synthase catalyzes glucose-phosphate transfer in addition to its characteristic glucose transfer reaction. Glucose-1,2-cyclic-phosphate (GCP) was proposed to be formed fro...
A 47-year-old man was referred to the Gastroenterology Department for investigation of a polypoid stomach mass detected incidentally at abdominal computed tomography (CT). The patient did not describe any history of gastric operation. Upper gastrointestinal endoscopy revealed a broad-based polypoid mass, approximately 25mm in diameter, at the greater curvature of the corpus. The surface of the ...
Digital surface models (DSMs) are widely used in forest science to model the forest canopy. Stereo pairs of very high resolution satellite and digital aerial images are relatively new and their absolute accuracy for DSM generation is largely unknown. For an assessment of these input data two DSMs based on a WorldView-2 stereo pair and a ADS80 DSM were generated with photogrammetric instruments....
ABSTRACT: NOAA images have been provided very useful environmental information from all over the world. In order to use NOAA images, they need to be transformed from image into map. This paper proposes a method that corrects the errors caused by this transformation. First, elevation errors are calculated and corrected based on elevation values, which are read from GTOPO30 database. These elevat...
In humans, neural tube failure to close during the 4th week of gestation leads to the development of severe congenital malformations of the central nervous system because of an error in maternal folate metabolism associated gene variants. The frequency of genotypic variants of GCP II (H475Y) and folate carrier RFCI (SLC19A1) gene polymorphism (80 G →A) were evaluated as potential candidate gene...
During normal cerebellar development, the remarkable expansion of granule cell progenitors (GCPs) generates a population of granule neurons that outnumbers the total neuronal population of the cerebral cortex, and provides a model for identifying signaling pathways that may be defective in medulloblastoma. While many studies focus on identifying pathways that promote growth of GCPs, a critical ...
