We prove a formula for the number of permutations in Sn such that their first n−k entries are increasing and their longest increasing subsequence has length n − k. This formula first appeared as a consequence of character polynomial calculations in the work of Adriano Garsia, [2]. We give an elementary proof of this result and also of its q-analogue. In [2], Adriano Garsia derived as a conseque...

PURPOSE Few data describe how often residents defer indirect patient care tasks to after hours or show whether residents report this time in duty hours logs. Thus, the authors examined how often residents perform one such task, discharge dictation, outside scheduled hours. METHOD The authors tracked all discharge summaries dictated by internal medicine residents at a single teaching hospital ...

T wenty years ago, David (one of the authors this article) was director a community college library in town with no public library. The college’s teacher education program excuse enough to maintain strong children’s collection, and kids from nearby elementary school would often spend afternoon Two particular stand out: sister brother who were nearly every day. They shy staff, but their enthusia...

The vast computing resources in graphics processing units (GPUs) have become very attractive for general purpose scientific computing over the past years. Moreover, central processing units (CPUs) consist of an increasing number of individual cores. Most applications today still make use of a single core only, because standard data types and algorithms in wide-spread procedural languages such a...

INTRODUCTION There is a young man who comes into the library frequently. He is about thirteen years old, one of the brightest in his school. He works for hours on the computer, surfing the Web or playing Sim City. Sometimes he chats with friends, trading computer secrets. Sometimes he spends hours patiently mentoring younger children on the computer. When this young man grows up, becomes a fath...

BACKGROUND AND PURPOSE Differential gene expression has been reported following the onset of focal stroke. To identify de novo expression of ischemia-induced genes, we applied subtractive cDNA library strategy to identify the genes that are selectively upregulated by focal stroke. METHODS Spontaneously hypertensive rats were subjected to permanent occlusion of the middle cerebral artery (MCAO...
