In our previous work, we have proposed a speaker modeling technique using spectral and pitch features for text-independent speaker identification based on Multi-Space Probability Distribution Gaussian Mixture Models (MSD-GMMs). We have presented a maximum likelihood (ML) estimation procedure for the MSD-GMM parameters and demonstrated its high recognition performance. In this paper, we describe...

BACKGROUND Unionization has been found to be related to higher filing of workers' compensation (WC) claims, but the extent of the relationship and the relationships to other variables have not been previously reported. METHODS Telephone interviews were conducted with both a population-based and WC-based samples of musculoskeletal disorder (MSD) cases. RESULTS Workers at unionized facilities...

BACKGROUND Musculoskeletal disorders (MSD) are a common cause of disability and absence from work. There is no consistent evidence in the literature regarding predictors for short- and long-term absences due to these disorders. AIMS To investigate work-related factors influencing short- and long-term absences due to MSD in German-speaking countries. METHODS The study is based on data from t...

From the standpoint of the mechanism of mechanochemical polymerization, two kinds of copolymeric prodrug, whose monomer sequence distribution (MSD) is different from each other, can be prepared by this polymerization under appropriate operational conditions: one is a random copolymer abundant in the longer block consisting of the same repeating units (multi-block copolymer), and the other is a ...

A monoclonal antibody-based sandwich direct ELISA (MSD-ELISA) method was previously developed for foot-and-mouth disease (FMD) viral antigen detection. Here we evaluated the sensitivity and specificity of two FMD viral antigen detection MSD-ELISAs and compared them with conventional indirect sandwich (IS)-ELISA. The MSD-ELISAs were able to detect the antigen in saliva samples of experimentally-...

background: musculoskeletal disorders are one of difficulties in communities that has negative effect on various aspect of life. the aim of this study was to evaluate musculoskeletal disorders in students.   materials and methods: in this study cross-sectional descriptive-analytic approach, 306 college students were enrolled by using no probability purposive sampling method and also availabilit...

BACKGROUND It is unclear whether the well-known risk factors for the occurrence of musculoskeletal disorders (MSD) also play an important role in the determining consequences of MSD in terms of sickness absence and health care use. METHODS A cross-sectional study was conducted among 853 shipyard employees. Data were collected by questionnaire on physical and psychosocial workload, need for re...

BACKGROUND Estimates of the extent of musculoskeletal disorders (MSD) are usually based upon workers' compensation reports, although recent reports indicate that there may be widespread under-reporting of MSD. METHODS An estimate of the incidence of arm and hand work-related MSD was made using capture-recapture analysis of the overlap between state workers' compensation reports and physician ...

OBJECTIVES We investigated the cause of the midsystolic drop (MSD) in left ventricular (LV) ejection velocities that are observed with hypertrophic cardiomyopathy (HCM) and severe obstruction. BACKGROUND Dynamic obstruction is an important determinant of symptoms and adverse outcome. The MSD in velocity and flow occurs in patients with gradients >60 mm Hg. The nadir velocity in the LV occurs ...
