Friedmann-Robertson-Walker cosmological models with a massive scalar field are studied in the presence of hydrodynamical matter in the form of a perfect fluid. The ratio of the number of solutions without inflation to the total number of solutions is evaluated, depending on the fluid density. It is shown that in a closed model this ratio can reach 60%, by contrast to ∼ 30% in models without flu...

BACKGROUND Identifying characteristics associated with transcranial magnetic stimulation (TMS) benefit would offer insight as to why some individuals experience tinnitus relief following TMS treatment, whereas others do not. The purpose of this study was to use the Tinnitus Functional Index (TFI) and its subscales to identify specific factors associated with TMS treatment responsiveness. METH...

BACKGROUND AND OBJECTIVES The study objective was to determine the influence of the 2001 and 2006 American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines changes on colposcopy training at one family medicine residency. METHODS We conducted a retrospective chart review from January 1, 2000 to October 31, 2009. The 2001 ASCCP guidelines were fully implemented into our practice...

Approximately one-third of embedded designers surveyed on the adoption and use of FPGAs for embedded applications responded that they perceived FPGAs as too expensive to use in their designs. However, a look at the total cost of ownership (TCO) at the system level (as measured by development, enhancement, replacement, and maintenance costs over the lifetime of the product) reveals that Altera® ...

OBJECTIVE To develop and validate a questionnaire to quantify disability associated with shoulder symptoms. METHODS A set of questions relevant to shoulder symptoms from a general disability interview was developed and the questionnaire applied to a cross-sectional population survey and a prospective study of general practice attenders. Subjects included adults who reported current shoulder p...

INTRODUCTION Few studies have documented the value of mentoring for medical students, and research has been limited to more subjective (e.g., job satisfaction, perceived career preparation) rather than objective outcomes. This study examined whether having a mentor is associated with match outcome (where a student matched based on their rank order list [ROL]). METHODS We sent a survey link to...

In this paper, we present a method to estimate the number of reconfiguration steps that a time-constrained algorithm can accommodate. This analysis demonstrates how one would attack the problem of partitioning a particular algorithm into pieces to for run time reconfiguration execution on a Atmel 40K FPGA. Our method consist in evaluating algorithm operators execution time from data flow graph....

Objective: To evaluate the READER model for critical reading by comparing it with a free appraisal, and to explore what factors influence different components of the model. Design: A randomised controlled trial in which two groups of general practitioners assessed three papers from the general practice section of the BMJ. Setting: Northern Ireland. Subjects: 243 general practitioners. Main outc...

Florida Everglades restoration plans are aimed at maintaining and restoring characteristic landscape features such as soil, vegetation, and hydrologic patterns. This study presents the results from an exhaustive spatial sampling of key soil properties in Water Conservation Area 1 (WCA 1), which is part of the northern Everglades. Three soil strata were sampled: floc, upper 0- to 10-cm soil laye...

Although the total number of new drugs (new chemical entities) approved has gradually decreased over the past decade, the proportion that are expensive biological agents has grown dramatically. In particular, the number of new biological agents registered for treating cancer—so called targeted therapies or personalised medicine—is increasing, and the costs of these treatments are rising too, wi...
