"... Laboratory tests are an important yet often under-appreciated component of healthcare and thehealth economy.1 It is estimated that as much as $56 billion will have been spent on laboratory diagnos-tic services in 2005.2 More important, laboratory tests by their very nature are designed to initiate a ..."

a cascade of decisions regarding further testing, prevention, or treatment—decisions that ultimately determine the course of illness and cost of healthcare for patients who receive them. A recent report estimated that although diagnostics account for 1.6 % of the Medicare total costs, they influence

Analyzing the Airwaves Auction

by R. Preston Mcafee, John Mcmillan - Journal of Economic Perspectives , 1998
"... The US government recently sold spectrum rights using an innovative auction design, the simultaneous ascending auction, invented by economic theorists. The auction outcomes were broadly consistent with the expectations of the theorists. The auction form should have many other applications. March 21, ..."

Antibiotic pharmacists in the ascendancy

by Kieran Hand - Journal of Antimicrobial Chemotherapy
"... Specialist pharmacists have become an established feature of the antibiotic stewardship landscape in hospitals throughout the UK over the last decade. This review examines the origins of the specialist antibiotic pharmacist and how the role has developed in recent years. Antibiotic pharmacists fulfi ..."

Group reaction time distributions and an analysis of distribution statistics

by Roger Ratcliff - Psychological Bulletin , 1979
"... A method of obtaining an average reaction time distribution for a group of subjects is described. The method is particularly useful for cases in which data from many subjects are available but there are only 10-20 reaction time observations per subject cell. Essentially, reaction times for each subj ..."

subject are organized in ascending order, and quantiles are calculated. The quantiles are then averaged over subjects to give group quantiles (cf. Vincent learning curves). From the group quantiles, a group reaction time distribution can be constructed. It is shown that this method of averaging is exact

the Ascending Aorta To the Editor:

by Rev Esp Cardiol
"... Surgery for acute type B aortic dissection (ABAD) is complex and has a high risk of morbidity and mortality. Endovascular stent-grafting has recently begun to be used in acute aortic syndrome with promising short-term and mid-term results.1-4 In certain cases, severe atherosclerotic degeneration of ..."

Speeding Up Ascending-Bid Auctions

by Yuzo Fujishima, David Mc Adams , Yoav Shoham , 1999
"... In recent years auctions have grown in interest within the AI community as innovative mechanisms for resource allocation. The primary contribution of this paper is to identify a family of hybrid auctions, called survival auctions, which combine the benefits of both sealed-bid auctions (namely, quick ..."

Surgical Considerations of TAA Ascending Aorta

by unknown authors
"... aorta, 10 % involve the arch, and 10 % involve the descending thoracic and abdominal aorta (TAAA).1 Contrast-enhanced computed tomogra-phy (CT) scanning and magnetic resonance an-giography are important diagnostic modalities, al-though the role of echocardiography is growing. Early diagnosis is of p ..."
Abstract - Add to MetaCart
growing number of cases, endovascular stenting techniques can be used to repair TAA.2 Recent advancements com-bine an initial open repair of ascending and arch aneurysms with an endovascular stenting of the descending aorta.3

Ascending subgroups of irreducible finitary linear groups

by U. Meierfrankenfeld - J. London Math. Soc , 1995
"... Let K a field and V a vector space over K. Let FGLK(V) be the finitary linear group of V over K, namely FGLK(V) = {g ∈ GLK(V) | [V,g] has finite K-dimension}. Subgroups of FGLK(V) are called finitary groups. Recently a good amount of work has been done towards a classification of the locally finite ..."

Ascending chain conditions in free Baxter algebras

by Li Guo - INTERNATIONAL JOURNAL OF ALGEBRA AND COMPUTATION , 2004
"... In this paper we study ascending chain conditions in a free Baxter algebra by making use of explicit constructions of free Baxter algebras that were obtained recently. We investigate ascending chain conditions both for ideals and for Baxter ideals. The free Baxter algebras under consideration includ ..."

Control of magnesium transport in the thick ascending limb

by Gary A. Quamme - Am. J. Physiol , 1989
"... 1989.-The mammalian renal thick ascending limb of Henle (TAL) reab-sorbs-55 % of the filtered magnesium; accordingly, it is the major segment involved in control of renal Mg balance. This review discusses recent evidence for passive and active transport of Mg through the paracellular and transcellul ..."
