The differences of vowel sounds among speakers are mainly caused by the morphological differences and different speaking styles of each speaker. The traditional vowel normalization methods in acoustic space are mainly concerned with the variance of acoustic features. There is no information of articulatory space taken into account. This paper proposed an approach to normalize vowel spectra by using...
Ebola hemorrhagic fever (EBHF), caused by Ebola virus (EBOV), is a type of fatal epidemic disease with highly pathogenic rate, highly infection rate, and highly mortality rate which has reemerged in West Africa in February, 2014, leading to a catastrophe in the local and trend of spreading worldwide. In order to prevent the disease from spreading further, it is necessary to have a research of the...
Myelin water fraction (MWF) based on multi-component T2 analysis is one promising biomarker for the myelin in the brain. Two smoothing algorithms are proposed and compared in this study. Then the feasibility of using 6 echoes to determine MWF is investigated. Finally the correlations between T2 weighted, T2-mapping, and myelin water images are clarified. It is found the improved smoothing algorithm...
The Online Mendelian Inheritance in Man (OMIM) database is a useful reference for human genetic diseases. By standardization of its data structure, we hereby provide a user-friendly interface purported for standardized input of new patient data. Automatic diagnosis and pathway discoveries maybe achieved through pair-wise comparison and association analysis of tree data. A website has been provided...
Diesel exhaust particles (DEPs) may increase symptom severity in allergic diseases. To examine possible interaction between DEPs effects and allergic responses, a pollen-sensitized and challenged mouse model of allergic airways disease was utilized. BAL mice were sensitized with 0.15 ml pollen extract or saline injected intraperitoneally on day 0 and day 7. One week after sensitization, mice were...
In vivo animal experimental research is performed to study the influence of magnetic nanoparticles on the pulse wave. An interventional pulse wave transducer is connected to the rabbit's blood circulation through the ingenious two-end carotid intubations, so that the pulse wave with low noise could be acquired. The data obtained before and after the injection of the magnetic nanoparticles, which have...
In vitro experiments had been conducted to simulate the embolism therapy using the magnetic nanoparticles. In the experiments the main variables are the mass concentration of the particles suspension (0.1%, 0.3%, 0.5%, 0.7% and 1.0%), the flow velocity (40–220 mm/s), the external magnetic induction intensity (0.3, 0.4 and 0.5 T), the nanoparticles diameter (20, 40 and 60 nm). The influences of the...
A dynamic model of the operating mechanism for a low voltage molded case circuit breaker (MCCB) was built based on virtual prototype technology, and then a test was done to verify this model, which showed that simulation results of virtual model were in agreement with test results of real prototype. After adding electric repulsion force to model, the operating time of mechanism was shortened about...
