We performed a comparative study to select the efficient mother wavelet (MWT) basis functions that optimally represent the signal characteristics of the electrical activity of the human brain during a working memory (WM) task recorded through electro-encephalography (EEG). Nineteen EEG electrodes were placed on the scalp following the 10-20 system. These electrodes were then grouped into five r...

STUDY OBJECTIVES The purpose of this study was to determine the relative contribution of the instruction to maintain wakefulness versus posture change as major components determining sleep latency in the MWT as compared to the MSLT. DESIGN AND SETTING After adaptation, subjects spent 3 nights and the following days in the laboratory. On each day, Ss had eight sleep latency measurements includ...

We assess the application of microwave tomography (MWT) for detection axillary lymph nodes (ALNs) in breast cancer patients. numerically study effects limiting angular view MWT, as probes can only be placed on a limited arc around region. also possibility increasing amount retrievable information by acquiring data two consecutive steps, with single antenna set different positions. finally exper...

EXCESSIVE SLEEPINESS IS DEFINED AS SLEEPINESS OCCURRING IN A SITUATION WHEN AN INDIVIDUAL WOULD BE EXPECTED TO BE AWAKE AND ALERT. It is a chronic problem for about 5% of the general population,1, 2 and it is the most common complaint evaluated by sleep disorder centers.1, 3 The most common causes of sleepiness include partial sleep deprivation, fragmented sleep and medication effects. Sleepine...

BACKGROUND The step test has been used to assess exercise capacity in patients with chronic respiratory disease; however, its use has not been described with regard to patients with bronchiectasis (BCT). OBJECTIVE This study assessed the reliability of the Chester step test (CST) and the modified incremental step test (MIST) and also correlated these tests with pulmonary function, heart rate ...

This report summarizes work to examine interstage heating and cooling options for multiple reheat helium Brayton cycle power conversion system (PCS) designs. Previous work has demonstrated that thermal powers in the range of 2400 MWt can be readily derived from combining multiple single-expansion units derived from the 600-MWt, vertical shaft gas-turbine module helium reactor (GT-MHR). This PCS...

We performed a retrospective chart review of consecutive patients discharged from an inpatient amputee rehabilitation program over a 2 yr period (January 2010-December 2011). Our objective was to determine barriers to the completion of a standardized maximum walk test (MWT) at discharge. Over the study period, there were 190 discharges. The sample had a mean age of 63.5 yr (standard deviation [...

Purpose. To determine whether the presence of cognitive impairment (CI) affects physical recovery of patients with chronic heart failure (CHF) undergoing a cardiac rehabilitation program (CRP). Methods. We enrolled 80 CHF patients (M/F = 53/27). CI was evaluated by means of the Mini-Mental State Examination (MMSE), exercise tolerance was evaluated by six-minute walking test (6 mwt). All patient...

BACKGROUND Solid evidence shows that cardiac resynchronization therapy (CRT) improves prognosis, physical capacity and quality of life in selected groups of patients with chronic heart failure (CHF). Nonetheless, marked percentage of patients seem not to benefit from CRT. MATERIAL AND METHODS Sixty consecutive patients (aged 66.3 +/- 8.7 years, 57 men - 95%, 3 women - 5%) with CHF (71.7% with...

Calculated energy consumed in 284 cow yr by individually fed Angus, Charolais and reciprocal cross cows was partitioned into m~intenance, weight change and milk production requirements. Total digestible nutrient (TDN) consumed in 94 heifer yr was partitioned into maintenance and weight change requirements. The cow year was subdivided into midgestation, late gestation and lactation periods that ...
