Purpose. To compare the diagnostic value of texture analysis- (TA-) derived parameters from out-of-phase T1W, in-phase and T2W images in classification early stage liver fibrosis. Methods. Patients clinically diagnosed with hepatitis B infection, who underwent biopsy noncontrast MRI scans, were enrolled. TA extracted T1-weighted (T1W), T2-weighted (T2W) calculated using Artificial Intelligent K...

This paper examines the relationship between the dynamics of large networks and of their smaller factor-networks (factors) obtained through the factorization of the network's graph representation. We speci cally examine dynamics of networks which have Z-matrix state matrices. We perform a Cartesian product decomposition on its network structure producing factors which also have Z-matrix dynamic...

Taiwanese tone sandhi, although a phrase-level pattern, has been argued to be essentially lexicalized. We thus expected it to be phonetically categorical and insensitive to pragmatic context. To test these predictions, we had native speakers read aloud pairs of sentences identical except for morphemes expected to be neutralized by tone sandhi, both across and within prosodic positions. Speakers...

AIM Type 2 diabetes is associated with stroke and cardiac dysfunction. We therefore investigated isolated middle cerebral arteries and coronary septal arteries from the diabetic Goto-Kakizaki (GK) rat model of nonobese type 2 diabetes. METHODS Myogenic tone and agonist-induced responses were investigated under isobaric conditions with simultaneous recording of [Ca2+]i. Rho-kinase and NO pathw...

In the present study, event-related brain potentials (ERP) were recorded to investigate the role of pitch accent and lexical tone in spoken discourse comprehension. Chinese was used as material to explore the potential difference in the nature and time course of brain responses to sentence meaning as indicated by pitch accent and to lexical meaning as indicated by tone. In both cases, the pitch...

Pitch experiments aimed at evaluating temporal pitch mechanism(s) often utilize complex sounds with only unresolved harmonic components, and a low-pass noise masker to eliminate the potential contribution of audible distortion products to the pitch percept. Herein we examine how: (i) masker induced reduction of neural distortion products (difference tone: DT; and cubic difference tone: CDT) alt...

This paper presents the development and evaluation of an HMM-based TTS system for the modern Hanoi dialect of Northern Vietnamese, a tonal language. A study of specific phonetic and prosodic features of Hanoi Vietnamese is discussed. Consequences on the design of an HMM-based TTS system are derived. Using this knowledge, a TTS system, called VTed, is then developed under the Mary TTS platform. ...
