Relative clauses (RCs) are subordinate clauses embedded within nominal phrases. Semantically, this embedded clause modifies the dominating nominal head. Syntactically, the nominal head is associated with an empty element within the subordinate clause. RCs have received great attention from language researchers as they demonstrate crucial properties of the human language. They enable recursion i...

Passive radar is a rapidly emerging technology with many distinct advantages over traditional radar. Its exploitation of “illuminators of opportunity” renders it covert, as well as less expensive. Several passive radar systems, such as Lockheed Martin’s Silent Sentry and John Sahr’s Manastash Ridge Radar at the University of Washington, are already capable of detecting and tracking aircraft. Ou...

Intercellular bridges called "ring canals" (RCs) resulting from incomplete cytokinesis play an essential role in intercellular communication in somatic and germinal tissues. During Drosophila oogenesis, RCs connect the maturing oocyte to nurse cells supporting its growth. Despite numerous genetic screens aimed at identifying genes involved in RC biogenesis and maturation, how RCs anchor to the ...

Reactive carbonyls are widespread species in living organisms and mainly known for their damaging effects. The most abundant reactive carbonyl species (RCS) are derived from oxidation of carbohydrates, lipids, and amino acids. Chemical modification of proteins, nucleic acids, and aminophospholipids by RCS results in cytotoxicity and mutagenicity. In addition to their direct toxicity, modificati...

قابهای خمشی فولادی از دیرباز به عنوان یکی از بهترین سیستمهای سازه ای برای مقاومت در برابر بارهای لرزه ای و ثقلی مد نظر طراحان قرار داشته اند و همواره در سالهای اخیر طراحی آنها بر اساس روشهای ارتجاعی صورت می گرفته است هر چند که همواره انتظار استفاده از رفتار غیر ارتجاعی این سازه ها می رفته است از طرفی بعد از وقوع زمین لرزه های ویرانر متعددی که در سالیان اخیر در نقاط مختلف دنیا به وقوع پیوستند مع...

BACKGROUND Robotic-assisted laparoscopy is popularly performed for colorectal disease. The objective of this meta-analysis was to compare the safety and efficacy of robotic-assisted colorectal surgery (RCS) and laparoscopic colorectal surgery (LCS) for colorectal disease based on randomized controlled trial studies. METHODS Literature searches of electronic databases (Pubmed, Web of Science, ...

In Escherichia coli, capsular colanic acid polysaccharide synthesis is regulated through the multistep RcsC-->YojN-->RcsB phosphorelay. By monitoring a hallmarked cps::lacZ reporter gene, we first searched for physiological stimuli that propagate the Rcs signaling system. The expression of cps::lacZ was activated when cells were grown at a low temperature (20 degrees C) in the presence of gluco...

با توجه به تکرار بیش از حد تابع گاوسی‌شکل لنگر خمشی ـ عمق $(M(z)-z)$، در نتایج بسیاری از آزمایش‌های تجربی و مدل‌سازی‌های فیزیکی و عددی استاتیکی ـ لرزه‌یی، پیشنهاد روابطی جدید برای استفاده از موقعیت ذکر شده، مناسب به نظر می‌رسد. روابط جدید پلی میان مفهوم پرکاربرد منحنی‌های $p-y$ و تلاش‌های داخلی سازه‌یی شمع، به شکل لنگر خمشی $M(z)$ در طول آن ایجاد می‌کنند. در مطالعه‌ی حاضر، تابع لنگر خمشی در عم...

Radar Cross Section (RCS) is one of the most considerable parameters for ship stealth design. As modern ships are larger than their predecessors, RCS must be managed at each design stage for its reduction. For predicting RCS of ship, Radar Cross Section Analysis Program (RACSAN) based on Kirchhoff approximation in high frequency range has been developed. This program can present RCS including m...

The reticulum cell sarcoma (RCS) 1 of S JL / J mice has been shown to express alien histocompatibility membrane antigens (1, 2). This form of tumor antigen is, by definition, present on cancerous, but not normal, syngeneic tissues. However, it differs from other forms of tumor-associated antigens because it is a normal membrane component of one or more strains allogeneic to the host (3). In the...
