BACKGROUND Dysfunction after thrombolytic therapy of acute myocardial infarction (MI) may be reversible. Early after myocardial infarction, both reversible and irreversible injury may be manifested by regional wall motion abnormalities. Improved wall thickening during dobutamine infusion (dobutamine-responsive wall motion) may accurately identify reversibly injured segments. METHODS AND RESUL...

An algorithm is described that allows log ( n ) processors to sort n records in just over 2n write cycles, together with suitable hardware to support the algorithm. The algorithm is a parallel version of the straight merge sort. The passes of the merge sort are run overlapped, with each pass supported by a separate processor. The intermediate files of a serial merge sort are replaced by first-i...

We derive a Godunov-type numerical flux for the class of strictly convex, homogeneous Hamiltonians that includes H(p; q) = pap2 + bq2 2 pq; 2 < ab: We combine our Godunov numerical fluxes with a simple GaussSeidel type iterations for solving the corresponding Hamilton-Jacobi Equations. The resulting algorithm is fast since it does not require a sorting strategy as does the fast marching method....

Consider a collection of weighted subsets of a ground set N. We present a tree-based greedy heuristic, Treedy, that for a given query subset Q of N and a tolerance d approximates the weighted sum over all subsets of Q within relative error d. It also enables approximate sampling of subset of Q proportionally to the weights within total variation distance d. Experimental results show that approx...

INTRODUCTION An earthquake measuring 6.6 on the Richter scale on 23 December 2003 devastated the city of Bam in southeastern Iran. During the response and recovery phases, considerable shortcomings were discovered. The dire situation in the affected area, a variety of urgently required interventions, and the large number of aid organizations involved brought about difficulties in management, co...

INTRODUCTION Pterygium is a fibrous growth seen in bulber conjunctiva.It is a non malignant growth which may cause visual impairment. MATERIAL AND METHODS Pterygium study was done on rural population in out patient department of NIMS Hospital and medical college, Jaipur, Rajasthan, India.Two hundred patients with 300 eyes which had Pterygium who attended the Eye OPD during 01/06/2011 to 01/03...

Uterine myomas are being observed in pregnancy more frequently now than in the past, because many women are delaying child bearing till their late thirties, which is the time for the greatest risk of the myoma growth. Traditionally, obstetricians are trained to avoid myomectomies during caesarean sections as severe haemorrhages can occur, which may often necessitate hysterectomies. Pedunculated...

We have previously characterized the trafficking of transferrin (Tf) through HEp2 human carcinoma cells (Ghosh, R. N., D. L. Gelman, and F. R. Maxfield, 1994. J. Cell Sci. 107:2177-2189). Early endosomes in these cells are comprised of both sorting endosomes and recycling compartments, which are distinct separate compartments. Endocytosed Tf initially appears in punctate sorting endosomes that ...
