One component in Additive Schwarz Method (ASM) Domain Decomposition (DD) preconditioners BPS89, SBG96] using inexact subdomain solvers Boe89, HLM91] consists in an operator extending the boundary data into the interior of each subdomain, i.e. a homogeneous extension with respect to the diierential operator given in that subdomain. This paper is concerned with the construction of cheap extension...

In this paper we present an overview of the field of distributed development of software systems and applications (DD). Based on an analysis of the published literature, we consider threats to communication, coordination and control in DD caused by Temporal Distance, Geographical Distance, and Socio-Cultural Distance. The analysis results in a more complete framework for reasoning in the DD dom...

Bovine digital dermatitis (DD) is the most important infectious disease associated with lameness in cattle worldwide. Since the disease was first described in 1974, a series of Treponema species concurrent with other microbes have been identified in DD lesions, suggesting a polymicrobial etiology. However, the pathogenesis of DD and the source of the causative microbes remain unclear. Here we c...

OBJECTIVE To discuss advantages and disadvantages of various routes of administration and delivery systems for acute migraine medications, and to assist family physicians in optimizing treatment for individual patients. QUALITY OF EVIDENCE A MEDLINE search from January 1966 to October 2000 and a Current

OBJECTIVE To outline current approaches to diagnosing and managing delirium in the elderly. QUALITY OF EVIDENCE A literature review was based on a MEDLINE search (1966 to 1998). Selected articles were reviewed and used as the basis for discussion of diagnosis and etiology. We planned to include all published randomized controlled trials regarding management but found only two. Consequently, we ...

OBJECTIVES The purpose of this study was to evaluate the incidence and prognostic implication of diastolic dysfunction (DD) occurring in the first year after transplant. BACKGROUND Diastolic dysfunction is a recognized complication in heart transplant recipients, but its true incidence and natural history has been poorly characterized. We studied the prognostic implication of DD, as defined b...

STUDY OBJECTIVES To determine the relationship between D dimer (DD) status and markers of disease activity in patients with sarcoidosis. DESIGN Prospective, observational analysis. SETTING Pulmonary clinic of a tertiary care, university-affiliated hospital. PATIENTS Consecutive individuals with newly diagnosed sarcoidosis. INTERVENTION Determination of serum DD. MEASUREMENTS AND RESUL...

Bovine digital dermatitis (DD) is a severe infectious disease causing lameness in dairy cattle worldwide and is an important ruminant welfare problem that has considerable economic issues. Bovine DD is endemic in many regions worldwide and it is important to understand this major disease so that effective control strategies can be identified. There is substantial evidence that specific treponem...

The purpose of this paper is to prove the L p (R n ; dd) boundedness, for p > 1, of the non-centered Hardy-Littlewood maximal operator associated with the Gaussian measure dd = e ?jxj 2 dx. Let dd = e ?jxj 2 dx be a Gaussian measure in Euclidean space R n. We consider the non-centered maximal function deened by Mf(x) = sup x2B 1 (B) Z B jfj dd; where the supremum is taken over all balls B in R ...

BACKGROUND AND PURPOSE Accurate assessment of the number and lesion characteristics of brain metastasis is very important in GKS. The purpose of this study was to compare the diagnostic efficacy of DD gadobutrol in the detection of brain metastases compared with a DD 0.5-mol/L gadolinium contrast, gadopentetate dimeglumine. MATERIALS AND METHODS Records of 27 patients (male to female ratio, 1...
