In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with average activation energy ≈ 70-80 meV which produce peak in the noise at T ≈ 35-40K. In addition, it shows clear evidence of tunnelling type two-level-systems (as in glasses) which show up in noise measurements below 3...

We propose to use the visual denotations of linguistic expressions (i.e. the set of images they describe) to define novel denotational similarity metrics, which we show to be at least as beneficial as distributional similarities for two tasks that require semantic inference. To compute these denotational similarities, we construct a denotation graph, i.e. a subsumption hierarchy over constituen...

The DragonDictateTM-30K automatic transcription system is a !arge vocabulary, discrete utterance, natural language speech recognition system. First-time users are not required to provide any initial training or enrollment speech data before using the system. Speech models for 16,000 frequent words I phrases of English are built-in. Powerful adaptation techniques dynamically build and refine up ...

The advent of video-sharing sites such as YouTube has led to an unprecedented Internet delivery of community-contributed video content. However, most of these videos are not quality-controlled. This paper reports a first attempt towards assessing web videos in terms of visual quality with significant tests on 30k web videos. We regard the quality assessment as a two-class classification problem...

The soybean allergenic protein, Gly m Bd 30K [Ogawa et al., J. Nutr. Sci. Vitaminol., 37, 555-565 (1991)] which is most strongly and frequently recognized by the IgE antibodies in sera of soybean-sensitive patients with atopic dermatitis, has been characterized. The allergen was isolated from the crude 7S-globulin fraction as an oligomeric form with a molecular weight of more than 3000,000 by g...

It was found that the fusion (His)6-movement proteins (MPs) of two tobamoviruses (TMV UI and a crucifer-infecting tobamovirus, crTMV) were efficient nonspecific translational repressors. The in vitro translation of viral RNAs was blocked by incomplete 30K MP-RNA complexes formed at the MP:RNA molar ratios of 100-150:1. Similar results were obtained with the barley stripe mosaic hordeivirus (BSM...

Binding of guinea-pig spermatozoa to the zona pellucida of homologous eggs has been reported to involve 'receptors' on the inner acrosomal membrane (Huang et al. 1981). These receptors can be blocked by sulphated polysaccharides such as fucoidan (Huang and Yanagimachi, 1984). The aims of the present investigation were to identify these putative zona receptors using 125I-fucoidan as a probe and ...
