Internet centers host services for e-banks, e-auctions and other clients. Hosting centers then must allocate servers among clients to maximize revenue. The limited number of servers, costs of reallocat-ing servers, and unpredictability of requests make server allocation optimization difficult. Based on the many similarities between server and honey bee colony forager allocation, we propose a ne...

The use of High Performance Computing (HPC) in commercial and consumer IT applications is becoming popular. HPC users need the ability to gain rapid and scalable access to high-end computing capabilities. Cloud computing promises to deliver such a computing infrastructure using data centers so that HPC users can access applications and data from a Cloud anywhere in the world on demand and pay b...

Organizations face increased pressures to continually advance knowledge and new technologies for their long-term success and prosperity. University research centers offer important interorganizational linkages for industry–university collaboration, conducive for advancing knowledge and new technologies. This study examined industry’s strategic objectives for establishing relationships with univ...

A problem of packing a limited number of unequal circles in a fixed size rectangular container is considered. The aim is to maximize the (weighted) number of circles placed into the container or minimize the waste. Frequently, the problem is formulated as a nonconvex continuous optimization problem which is solved by heuristic techniques combined with local search procedures. A new formulation ...

Constructing atomically dispersed platinum (Pt) electrocatalysts is essential to build high-performance and cost-effective electrochemical water-splitting systems. We present a novel strategy to realize the traction and stabilization of isolated Pt atoms in the nitrogen-containing porous carbon matrix (Pt@PCM). In comparison with the commercial Pt/C catalyst (20 weight %), the as-prepared Pt@PC...

PURPOSE The purpose of this study was to analyze the educational quality of laparoscopic cholecystectomy (LC) videos accessible on YouTube, one of the most important sources of internet-based medical information. METHODS The keyword 'laparoscopic cholecystectomy' was used to search on YouTube and the first 100 videos were analyzed. Among them, 27 videos were excluded and 73 videos were includ...

Today I would like to speak to you about the remarkable successes of academic medical centers to date, the significant problems that we are now facing, and the need for us to evolve into the next generation of academic medical centers. Academic medical centers have been remarkably successful in fulfilling our three missions of clinical care, research, and education. We graduate 17,000 physician...

With the introduction of blade servers and the emergence of techniques for spreading applications over clusters to exploit scalability, we’re suddenly seeing the emergence of enormous data centers. Google is said to operate more than 100,000 computers in its centers; Amazon has grown from perhaps 25 machines to as many as 2500 over just a few years, and similar stories are now common. These kin...

During the past two decades, the involvement of non-academic sponsors of biomedical research, particularly clinical trial research, has increased exponentially. It is estimated that between 1980 and 2003 the overall research and development expenditure by US pharmaceutical companies increased from $2 billion to $33 billion [1]. The sources of funding for biomedical research have also shifted si...
