This paper investigates the performance of the T-distributions as compared to other well known time-frequency distributions in a recently proposed blind source separation algorithm based on timefrequency analysis. In this study we considered linear FM signals (chirps), non-linear FM signals, and doppler signals. Keyword:Blind Source Separation; Time-frequency representation; Doppler signal; Lin...
The aim of the present study was to compare the benefit of monaural versus binaural ear-level frequency modulated (FM) fitting on speech perception in noise in children with normal hearing. Reception threshold for sentences (RTS) was measured in no-FM, monaural FM, and binaural FM conditions in 22 normally developing children with bilateral normal hearing, aged 8 to 9 years old. Data were gathe...
Women with fibromyalgia (FM) often complain of whole-body pain, and muscle fatigue, which may be related to autonomic dysfunction. Therefore, the purpose of the present study was to investigate the effects of resistance exercise training (RET) on disease impact, pain catastrophizing, and autonomic modulation in women with FM. Women with FM (n=26) and healthy control women (HC: n=9), aged 19-65 ...
One hundred forty-six abdominally obese adults age 60-80 yr were studied to investigate the interaction between cardiorespiratory fitness (CRF) and obesity on functional limitation. Obesity was determined by fat mass (FM), CRF was determined by a maximal treadmill test, and functional limitation was based on 4 different tasks that are predictive of subsequent disability. Both FM (r = -.34, p ≤ ...
BACKGROUND Women with fibromyalgia (FM) describe great difficulties in managing work. Reported work ability in women with FM varies from 34 to 77 percent in studies from different countries. Many factors are suggested to affect the ability to work in women with FM, including pain, fatigue, impaired physical capacity and activity limitations. However, it is difficult to define to which extent sy...
The FM-index is a succinct text index needing only O(Hkn) bits of space, where n is the text size and Hk is the kth order entropy of the text. FM-index assumes constant alphabet; it uses exponential space in the alphabet size, σ. In this paper we show how the same ideas can be used to obtain an index needing O(Hkn) bits of space, with the constant factor depending only logarithmically on σ. Our...
We present here a six-species comparison of tree-ring growth response to extremes (below the 30th and above the 70th percentile) in temperature, precipitation, and corresponding streamflow. The species compared are Pinus edulis (PIED), Pseudotsuga menziesii (PSME), Pinus ponderosa (PIPO), Pinus flexilis (PIFL), Pinus aristata (PIAR), and Picea engelmannii (PCEN). Sensitivity was determined usin...
Recently introduced frequency modulation (FM) systems provide an adaptive adjustment to the emphasis of the FM system through the user’s hearing aid via VoicePriority iTM (VPi). VPi measures the noise level at the listener’s hearing aid microphone and adds gain to the FM signal when the background noise increases to a detrimental level. However, the potential benefi t of VPi technology has yet ...
Although family medicine (FM) is the most commonly practiced specialty among all the medical specialties, its practice patterns have seldom been analyzed. Looking at data from Taiwan's National Health Insurance Research Database, the current study analyzed ambulatory visits to FM specialists nationwide. From a sample dataset that randomly sampled one out of every 500 cases among a total of 309,...
BACKGROUND Direct smear microscopy using Ziehl-Neelsen (ZN) staining is the mainstay of tuberculosis (TB) diagnosis in most high burden countries, but is limited by low sensitivity in routine practice, particularly in high human immunodeficiency virus (HIV) prevalence settings. METHODS We compared the performance of three commercial light emitting diode (LED)-based microscopy systems (Primost...
