The segment model (SM) is a family of methods using segmental distribution rather than frame-based features (e.g. HMM) to represent the underlying characteristics of the observation sequence. It has been proved to be more precise than that of HMM. However, the high complexity prevents these models' use in practical systems. In this paper we present a(More)
Salicylic acid (SA) functions in the plant response to drought stress were assessed using SA-altering Arabidopsis mutants, including snc1 (with constitutively high levels of SA) and its nahG-transformed plants (named as snc1/nahG, with a comparable SA level to the wild type), sid2 and transgenic line nahG (both with SA deficiency), and npr1-1 (with SA(More)

Observation of tongue coating, a foundation for clinical diagnosis and treatment in traditional Chinese medicine (TCM), is a major indicator of the occurrence, development, and prognosis of disease. The biological basis of tongue diagnosis and relationship between the types and microorganisms of tongue coating remain elusive. Thirteen chronic erosive(More)
It is described in this paper for the application of pitch/tone information in the parametric trajectory model. Pitch as a dynamic feature and its contours—tone as a segmental-level feature are deserved their own particular characteristics, which match case of parametric trajectory model better compared with MFCC and energy. Here we give an improved(More)
