In the framework of perfect loop nests with uniform dependences, tiling is a technique used to group elemental computation points so as to increase computation granularity and to reduce the overhead due to communication time. We review existing approaches from the literature, together with the optimization criteria that are used for determining a \good" or \optimal" tiling. Then we explain the ...

Adult humans often undertake acute fasts for cosmetic, religious or medical reasons. For example, an estimated 14% of US adults have reported using fasting as a means to control body weight and this approach has long been advocated as an intermittent treatment for gross refractory obesity. There are unique historical data sets on extreme forms of food restriction that give insight into the cons...

Efficient movement underpins all great sporting performances. When performed by an expert, complex movements can appear effortless, almost simple; as Leonardo Da Vinci stated, “simplicity is the ultimate sophistication”. Dynamic control of movement is also central to safe sporting function and is dependent on the sophisticated integration of a range of factors including environment, nature of t...

We propose a relatively simple, accurate and flexible approach to forecasting the distribution of defaulted debt recovery outcomes. Our approach is based on mixtures of Gaussian distributions, explicitly conditioned on borrower characteristics, debt instrument characteristics and credit conditions at the time of default. Using Moody’s Ultimate Recovery Database, we show that our mixture specifi...

A C S s I write this we are just entering the holiday season; you will e reading this in the midst of the holidays. This is traditionally time when thoughts become more philosophical than scienific. It often engenders contemplation of the actual importance f material things and what brings real happiness. I recently ad an interaction with a patient and his family that caused me o pause and cons...

Injuries sustained while playing Ultimate at six tournaments between 1986 and 1990 were recorded. Thigh muscle strains, ankle ligament sprains and skin abrasions/friction burns were the most frequent injuries. Factors contributing to injury include pitch state, player fitness and preparation, clothing, 'lay-out' technique, tournament organization and squad size. Reducing excessive playing time,...

To make informed forecasting and replenishment decisions, many companies bring together operational elements of production and distribution with sales and marketing, executing Sales and Operations Planning (S&OP) collaborative improvement processes. As cross-functional and consensus-based processes, S&OP activities create value by keeping supply and demand in balance. But most S&OP arrangements...

The class UP of ‘ultimate polynomial time’ problems over C is introduced; it contains the class P of polynomial time problems over C. The τ -Conjecture for polynomials implies that UP does not contain the class of non-deterministic polynomial time problems definable without constants over C. This latest statement implies that P 6 = NP over C. A notion of ‘ultimate complexity’ of a problem is su...
