background: liver cancer mortality is high in thailand but utility of related vital statistics is limited due to national vital registration (vr) data being under reported for specific causes of deaths. accurate methodologies and reliable supplementary data are needed to provide worthy national vital statistics. this study aimed to model liver cancer deaths based on verbal autopsy (va) study in...

he protein aggregates of various neuro-degenerative diseases are not created equal. So say Matsumoto et al. (page 75), who find that the aggregates of familial amyo-trophic lateral sclerosis (fALS) are unusually porous compared to those of Huntington's disease (HD). Both diseases are associated with the neuronal aggregation of a mutant protein in affected individuals. For fALS, the mutant prote...

The reliability and sensitivity analyses of stator blade regulator usually involve complex characteristics like high-nonlinearity, multi-failure regions, small failure probability, which brings in unacceptable computing efficiency accuracy the current analysis methods. In this case, by fitting implicit limit state function (LSF) with active Kriging (AK) model reducing candidate sample pool adap...

The first issue of Thorax was published 32 years ago. Until recently, the journal was owned by the British Medical Association but its contents and editorial policy were controlled by the Thoracic Society. From the beginning of this year, as a result of a new agreement, Thorax will be owned jointly by the British Medical Association and the Thoracic Society. We hope that our readers will take p...

This study revisits the issue of tonal registers by exploring the cues used in producing and perceiving the five level tones of Black Miao. Both production and perception experiments show that non-modal phonations are very important cues for tonal contrasts. Two different kinds of non-modal phonations that either enhance pitch contrasts or provide an additional contrastive cue divide tonal leve...

Introduction: Myocardial perfusion imaging is a nuclear medicine imaging method that is used to detect coronary artery diseases. One of the main sources of error in this imaging method is the detection of Compton scattered photons in the photopeak energy window used for data acquisition. This results in the degradation of the image contrast, and therefore decreases the...
