Shared idiotypy between B- and T-cell receptors specific for the antigen L-tyrosine-p-azophenyltrimethylammonium [tyr(TMA)] was studied in an antigen-binding assay using idiotypic antisera. These idiotypic reagents were prepared by inoculation of rabbits with purified anti-tyr(TMA) antibody raised in strain 13 guinea pigs. The antisera blocked 78-83% of the antigen-binding T cells (T-ABC) and 5...
In this study, an ABC-Local Search (ABC-Ls) method was proposed by including a new local search procedure into the standard artificial bee colony (ABC) algorithm to perform parameter estimation of photovoltaic systems (PV). The aim ABC-Ls improve exploration capability ABC with in addition exploitation and balance algorithm. first tested on 15 well-known benchmark functions literature. results ...
The ATP-binding cassette (ABC) gene family is considered to be one of the largest gene families in all forms of prokaryotic and eukaryotic life. Although the ABC transporter genes have been annotated in some species, detailed information about the ABC superfamily and the evolutionary characterization of ABC genes in common carp (Cyprinus carpio) are still unclear. In this research, we identifie...
Artificial bee colony algorithm (ABC) is an efficient and popular evolutionary (EAs), which has been attracted wide attention by researchers, improved ABC with various characteristics (ABCs) have proposed. It widely acknowledged that the search operator core element in performance of ABC. However, generally designed operators ABCs are rotation-variable processes dependent mainly on natural coor...
آنزیم کندروئیتیناز abc iیک آنزیم باکتریایی با وزن مولکولی در حدود kda 112.5 و 997 اسیدآمینه است و به خانواده کندروئیتیناز ها تعلق دارد. این آنزیم قادر است galag ها (گالاکتوزآمینوگلیکان) را بشکند و ویژگی سوبسترایی وسیعی دارد ودر بین سوبستراهای گلیکوزآمینوگلیکان، کندرئیتین 4-سولفات، کندرئیتین 6-سولفات، درماتان سولفات و هیالورونیک اسید را با مکانیسم حذف ? می شکند. در مطالعات قبلی، کلونینگ و بیان آ...
We define Anderson-Brown-Cisinski (ABC) cofibration categories, and construct homotopy colimits of diagrams of objects in ABC cofibraction categories. Homotopy colimits for Quillen model categories are obtained as a particular case. We attach to each ABC cofibration category a right derivator. A dual theory is developed for homotopy limits in ABC fibration categories and for left derivators. Th...
The activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) relies on chronic active B-cell receptor (BCR) signaling. BCR pathway inhibitors induce remissions in a subset of ABC DLBCL patients. BCR microclusters on the surface of ABC cells resemble those generated following antigen engagement of normal B cells. We speculated that binding of lymphoma BCRs to self-antigens in...
ABC (Artificial Bee Colony) algorithm is one of the most popular approaches that is used in optimization problems. ABC overcomes other well-known heuristic methods, such as GA, PSO and DE (Differential Evolution). In this paper, we propose a hybrid ABC-DE algorithm that combines properties of ABC and DE approaches. The results show that our proposed algorithm is better than both ABC and DE and ...
A theoretical and numerical analysis of Liao's absorbing boundary condition (ABC) is presented. The form of the ABC is related to both space-time polynomial extrapolation and a one-way wave equation. A modi cation allowing the optimization of the ABC for speci c angles of incidence or wave speeds is discussed. The stability of the ABC is also discussed, and a technique is presented for enhancin...
در این مقاله، مسئلۀ برنامهریزی یکپارچۀ منابع (irp) با استفاده از نوعی مدل بهینهسازی با حداقل هزینه، مدلسازی شده است. در این مدل، تابع هدف مجموع هزینههای سرمایهگذاری، بهرهبرداری و تعمیرات و نگهداری منابع سمت تولید و همچنین هزینۀ اجرای برنامههای مدیریت بار است. قابلیت اطمینان سیستم، با استفاده از شاخص های مقدار انتظاری انرژی تأمین نشده (eens) و احتمال تأمین نشدن بار (lolp)، برآورد و تأمی...
