The objective of this study was to compare different modeling strategies to identify individual and admissions characteristics associated with readmission to a general hospital. Routine data recorded in the Hospital Information System on all admissions to the Regional Public Hospital of Betim, Minas Gerais State, Brazil, from July 1996 to June 2000 were analyzed. Cox proportional hazards model ...

Abstract Brain-computer interface (BCI) is believed to be the translator of brain signals into actions based on model, built machine learning (ML) algorithms, incorporated in it. This study reports performance various ML algorithms evaluating efficacy neurofeedback applied for treatment central neuropathic pain (CNP). In first phase this study, we different classification electroencephalography...

In this paper, for real time enhancement of noisy speech, a method of threshold determination based on modeling of Teager energy (TE) operated perceptual wavelet packet (PWP) coe cients of the noisy speech and noise by an Erlang-2 PDF is presented. The proposed method is computationally much faster than the existing wavelet packet based thresholding methods. A custom thresholding function based...

In clinical cardiac tamponade, open-catheter intrapericardial pressure (IPP) may be used to estimate left ventricular transmural filling pressure (TMFP). However, it has been suggested recently that right atrial pressure (RAP) is superior to IPP in assessing true extracardiac pressure during pericardial drainage. In 10 patients with subacute cardiac tamponade, pulmonary wedge pressure (PWP), RA...

Hemodynamic data were obtained in 9 patients (mean age 65 yrs) with carotid territory cerebral infarct within the preceding 24 hours (mean 14 +/- 8) as part of a pilot study testing the feasibility and safety of hypervolemic hemodilution. Pulmonary arterial catheters (PACs) were placed without complication in all patients, and after baseline measurements were obtained, up to 1500 cc of 6% hetas...

The aim of this research was (a) to determine the extent of therapist effects in Psychological Wellbeing Practitioners (PWPs) delivering guided self-help in IAPT services and (b) to identify factors that defined effective PWP clinical practice. Using patient (N = 1122) anxiety and depression outcomes (PHQ-9 and GAD-7), the effectiveness of N = 21 PWPs across 6 service sites was examined using m...

We address the problem of gauging the influence exerted by a given country on the global trade market from the viewpoint of complex networks. In particular, we apply the PWP method for computing indirect influences on the world trade network.

The fine-grained soil including the problematic ones can cause many difficulties in project accomplishment. Settlement and swelling are among the problems of the fine-grained soils. The present study compared the effects of the polypropylene waste plastic (PWP) and glass fiber reinforced polymer (GFRP) on geotechnical properties of the clayey soils for the subgrade design. To this end, the PWP ...

This paper presents a speech enhancement method, where an adaptive threshold is statistically determined based on Gaussian modeling of Teager energy (TE) operated perceptual wavelet packet (PWP) coe cients of noisy speech. In order to obtain an enhanced speech, the threshold thus derived is applied upon the PWP coe cients by employing a Gaussian pdf dependent custom thresholding function, which...
