The framework of Integral Quadratic Constraints (IQC) introduced by Lessard et al. (2014) reduces the computation of upper bounds on the convergence rate of several optimization algorithms to semi-definite programming (SDP). In particular, this technique was applied to Nesterov’s accelerated method (NAM). For quadratic functions, this SDP was explicitly solved leading to a new bound on the conv...

Few first-rate biologists start their careers with only one ‘A-level’ (High School qualification) and a job in a copper wire factory. Fewer still go on to command a research budget of £250 million a year. But then Mike Dexter, who takes over this summer as director of the UK’s Wellcome Trust, the world’s biggest medical research charity, has always done things his own way. Dexter joins the Trus...

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

This paper shows how KARO (Knowledge Acquisition Environment with Reusable Ontoiogies) supports the development of the domain layer in MIKE (Model-based and Incremental Knowledge Engineering). KARO supplements the reuse of generic problem-solving methods at the task and inference layers in MIKE with a commonsense ontology at the domain layer. The intention is to make the development process eas...

Sub-optimal infant and young child feeding (IYCF) practices are likely a significant contributor to high undernutrition rates in Viet Nam. To date, however, there has been no comprehensive review of IYCF practices in Viet Nam. The objectives of this paper were to review: 1) patterns/trends in IYCF in Viet Nam; 2) the barriers and facilitators to IYCF practices; and 3) interventions and policies...

Nicotinamide (NAM), a form of vitamin B3, is a byproduct and noncompetitive inhibitor of the deacetylation reaction catalyzed by Sirtuins. These represent a family of evolutionarily conserved NAD+-dependent deacetylases that are well-known critical regulators of metabolism and aging and whose founding member is Sir2 of Saccharomyces cerevisiae. Here, we investigated the effects of NAM supplemen...

John Michael Harrison (Mike Harrison) was born in London, England on February 2, 1915 and died on November 30, 2007 at his home in Brookline, MA. He received his early education at Stonyhurst College and then graduated from the Institution of Electrical Engineering, London, in 1942. He then obtained a postgraduate academic diploma in psychology from University College and Birkbeck College, Univ...
