A New Coat

White coat ceremonies for new medical students.

Patient coat, doctor coat.

In those hands I see chipped plates, plastic sofa case, dripping taps, the smell of too little tenement light, of urine rained on hapless clothes, a smell her grandson will call stale and will define everything in life he will forever run from. Her sallow hands, atrophic from not holding and not being held, like garaged brush stiffened with last year’s paint; hands that rest, as she finishes, o...

New insights into the structural mechanisms of the COPII coat.

In eukaryotes, coat protein complex II (COPII) proteins are involved in transporting cargo proteins from the endoplasmic reticulum (ER) to the Golgi apparatus. The COPII proteins, Sar1, Sec23/24, and Sec13/31 polymerize into a coat that gathers cargo proteins into a coated vesicle. Structures have been recently solved of individual COPII proteins, COPII proteins in complex with cargo, and highe...

solution of security constrained unit commitment problem by a new multi-objective optimization method

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

An RNA decay factor wears a new coat: UPF3B modulates translation termination

Nonsense-mediated RNA decay (NMD) is a highly conserved and selective RNA turnover pathway that has been subject to intense scrutiny. NMD identifies and degrades subsets of normal RNAs, as well as abnormal mRNAs containing premature termination codons. A core factor in this pathway-UPF3B-is an adaptor protein that serves as an NMD amplifier and an NMD branch-specific factor. UPF3B is encoded by...
