Working memory is thought to involve separate modality-specific storage systems. Interactions between these storage systems were investigated using a novel cross-modal 2-back paradigm. 2-back, 1-back and target items were presented either visually as a verbalizable linedrawing or auditorily as a digitized spoken word. ERPs for auditory targets were(More)
A multi-HMM speaker-independent isolated word recognition system is described. In this system , three vector quantization methods, the LBG algorithm, the EM algorithm, and a new MGC algorithm, are used for the classiication of the speech space. These quantizations of the speech space are then used to produce three HMMs for each word in the vocabulary. In(More)
In this paper, we describe the work on Chinese multi-dialect speech processing. Based on the phonetic analysis of ten Chinese dialects, we have created a Chinese super phonetic system for the Chinese speech recognition. To exam this phonetic system and develop Chinese dialect speech technology, we are building a multi-dialect speech corpus, which includes(More)
Duchenne muscular dystrophy (DMD) is a severe hereditary myopathy. Standard treatment by glucocorticosteroids is limited because of numerous side effects. The aim of this study was to test immunomodulation by human immunoglobulin G (IgG) as treatment in the experimental mouse model (mdx) of DMD. 2 g/kg human IgG compared to human albumin was injected(More)
Photochemical treatment is increasingly being applied to remedy environmental problems. TiO2-derived catalysts are efficiently and widely used in photodegradation applications. The efficiency of various photochemical treatments, namely, the use of UV irradiation without catalyst or with TiO2/graphene-TiO2 photodegradation methods was determined by comparing(More)
