چکیده: در این مقاله، مسئله بهره‏برداری بهینه شبکه توزیع فعال (adn) [i] برای حضور در بازار انرژی همزمان با رزروچرخان و متوالی توان راکتیو با در نظر گرفتن مفهوم نیروگاه مجازی فنی بررسی شده ‏است. نیروگاه مجازی فنی با لحاظ کردن قیود شبکه و منابع انرژی پراکنده‏ (der)[ii] تحت پوشش خود، امکان بهره‏برداری فعال شبکه توزیع را با هدف حداکثر سازی سود به منظور حضور در بازارهای مذکور فراهم می‏کند. به منظور پ...

We investigate whether models with flat extra dimensions in which SM fields propagate can give a significant contribution to the anomalous magnetic moment of the muon (MMM). In models with only SM gauge and Higgs fields in the bulk, the contribution to the MMM from Kaluza-Klein (KK) excitations of gauge bosons is very small. This is due to the constraint on the size of the extra dimensions from...

Diborane (B(2)H(6)), a high energy density material, was believed to be stable in a wide P, T interval. A systematic investigation of the B-H system using the ab initio variable-composition evolutionary simulations shows that boron monohydride (BH) is thermodynamically stable and can coexist with solid B, H(2), and B(2)H(6) in a wide pressure range above 50 GPa. B(2)H(6) becomes unstable and de...

BACKGROUND AND OBJECTIVES Polycythemia vera (PV) is unusual in young patients, so that little information is available on long-term clinical evolution in this particular group. The aim of this study was to define the long-term risk of thrombosis, acute leukemia (AL) and myelofibrosis with myeloid metaplasia (MMM) in young PV patients. DESIGN AND METHODS From 1975 to 2000, 70 PV patients aged ...

BACKGROUND AND OBJECTIVE Severe anemia is the outstanding problem in approximately 50 percent of patients with myelofibrosis with myeloid metaplasia (MMM). The present trial was based on the considerations that abnormal immune responses are frequently associated with MMM and that cyclosporin A (Cy-A) has proven to be effective in improving anemia in autoimmune disorders. The aim of this study w...

Parallel Matrix Matrix Multiplication (MMM) is used in scientific codes across many disciplines. While it has been widely studied how to optimally divide MMM among homogenous compute nodes, the optimal solution for heterogeneous systems remains an open problem. Dividing MMM across multiple processors or clusters requires consideration of the performance characteristics of both the computation a...

A major bottleneck in comparative protein structure modeling is the quality of input alignment between the target sequence and the template structure. A number of alignment methods are available, but none of these techniques produce consistently good solutions for all cases. Alignments produced by alternative methods may be superior in certain segments but inferior in others when compared to ea...

The purpose of this study was to investigate the molecular biological characteristics of malignant mucosal melanoma (MMM) and adenoid cystic carcinoma (ACC) of the head and neck. We analyzed the common genetic abnormalities that may help to identify the loci in the genes involved in the development of MMM and ACC of the head and neck by PCR-LOH on chromosomes 1p, 6q, 9p, 10q, 11q, 12q, 17p, and...
