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...

Error recovery in compiler design and construction is a wellknown area of Computer Science. Traditionally, the compiler’s responsibility has been to identify all possible errors in one pass of the source code in as short a period of real time as possible. However, in certain situations, it is more desirable to have the compiler act ‘intelligently’ by making ‘intelligent’ code changes and by off...

In this paper, we begin by presenting the 17 case of acute lumbar paraspinal compartment syndrome in the scientific/medical literature. We then review all 17 cases for demographic and clinical characteristics, in particular in terms of how they influence ultimate outcomes. All but one case occurred in a male, and most patients were less than age 40 (71%). Symptoms typically were precipitated by...

The N2 flooding enhanced oil recovery process is an important technical means for the development of low permeability reservoirs due to its good energy enhancement effect and injectivity. Low have a large span strong heterogeneity, which will significant impact on gas injection development. In order explore influence matrix fractures production characteristics flooding, this study conducted ser...
