This report summarizes the proceedings of the 9th workshop of the Genomic Standards Consortium (GSC), held at the J. Craig Venter Institute, Rockville, MD, USA. It was the first GSC workshop to have open registration and attracted over 90 participants. This workshop featured sessions that provided overviews of the full range of ongoing GSC projects. It included sessions on Standards in Genomic ...
RPCs with float glass electrodes (GSC or glass RPC) have been proposed as active elements for large-detectors (e.g. MONOLITH). Industrial large-scale GSC production has to be standardized in order to have homogeneous, affordable and reproducible detectors. A wide range of industrial glass treatments are already exploited by both glass and automobile industries. Our efforts are aimed to import a...
RNA modifications play critical roles in important biological processes. However, the functions of N6-methyladenosine (m6A) mRNA modification in cancer biology and cancer stem cells remain largely unknown. Here, we show that m6A mRNA modification is critical for glioblastoma stem cell (GSC) self-renewal and tumorigenesis. Knockdown of METTL3 or METTL14, key components of the RNA methyltransfera...
This paper aims to make a comparative analysis between the personal profiling capabilities of the two most important free citation-based academic search engines, namely Microsoft Academic Search (MAS) and Google Scholar Citations (GSC). Author profiles can be very useful for evaluation purposes once the advantages and the shortcomings of these services are described and taken into consideration...
Germline stem cell (GSC) self-renewal and differentiation are required for the sustained production of gametes. GSC differentiation in Drosophila oogenesis requires expression of the histone methyltransferase dSETDB1 by the somatic niche, however its function in this process is unknown. Here, we show that dSETDB1 is required for the expression of a Wnt ligand, Drosophila Wingless type mouse mam...
The high dimensionality of functional magnetic resonance imaging (fMRI) data presents major challenges to fMRI pattern classification. Directly applying standard classifiers often results in overfitting, which limits the generalizability of the results. In this paper, we propose a new group of classifiers, “Generalized Sparse Classifiers” (GSC), to alleviate this overfitting problem. GSC draws ...
در سال های اخیر روش های شکل دهی پرتو وفقی به منظور افزایش کیفیت تصاویر اولتراسوند به کار گرفته شده اند. این روش ها به دلیل استفاده از اطلاعات محیط و به روز کردن وزن های اعمالی به اجزای آرایه به صورت لحظه به لحظه، موفقیت زیادی در بهبود قدرت تفکیک تصاویر اولتراسوند داشته اند. ولی این افزایش قدرت تفکیک به بهای کاهش کنتراست تصاویر اولتراسوند نسبت به روش های غیروفقی به دست می آید. در این مقاله روشی ...
In order to implement or maintain a green supply chain (GSC) that produces goods and services responsibly sustainably, managers should use tools allow for the efficient identification, quantification, mitigation of ever-present risks. The objective present research is identify risk factors associated with processes involved in GSC management. Based on an analysis characteristics risk, authors p...
The flow of high-temperature and compositionally enriched material between mantle plumes nearby spreading centers influences up to 30% the global mid-ocean ridge system represents a significant, but currently unconstrained, flux volatiles out mantle. Here, we present new analyses H2O, F, Cl, S in basaltic glass chips from an archetypal region plume-ridge interaction, Galápagos Spreading Center ...
در این پایان نامه به بررسی استفاده از آرایه دایره ای یکنواخت می پردازیم. شکل دهی پرتو و جهت یابی از مهم ترین کاربردهای آرایه است. در مبحث شکل دهی پرتو، با استفاده از آرایه های دایره ای قادریم هم در حوزه ارتفاع و هم در حوزه سمت پرتوسازی کنیم. البته توجه داریم که بیشترین کاربرد آرایه های دایره ای این است که به ازای یک زاویه ارتفاع مشخص، در حوزه زاویه ای سمت پرتو سازی کنیم. لذا در این پایان نامه ع...
