A variant of Heapsort|named Ultimate Heapsort|is presented that sorts n elements in-place in (n log 2 (n + 1)) worst-case time by performing at most n log 2 n + (n) key comparisons and n log 2 n + (n) element moves. The secret behind Ultimate Heapsort is that it occasionally transforms the heap it operates with to a two-layer heap which keeps small elements at the leaves. Basically, Ultimate He...

A book which tells the story of the children's early life, the horrors endured on the way to Belsen and in the camp, can hardly fail to be moving. This book is intensely so. The patient handling of the children after their arrival in Ireland and the gradual building of confidence is not the least moving section. This may be due to a certain lack of "expertise" in the handling of the early part ...

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...

In several countries, low-level radioactive wastes are treated and stored awaiting construction and operation of a final repository. In some cases, interim storage may be extended for decades requiring special attention regarding security issues. The International Atomic Energy Agency (IAEA) recommends segregation of wastes that may be exempted from interim storage or ultimate disposal. The pap...

We demonstrate the quality factor Q - (0.8 +/- 0.1) x 10(10) of whispering-gallery modes in fused-silica microspheres at 633 nm, close to the ultimate level determined by fundamental material attenuation as measured in optical fibers. The lifetime of ultimate Q is limited by adsorption of atmospheric water. Monitoring of adsorption kinetics with submonolayer sensitivity by Q factors and frequen...

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,...
