© 2011 Seungkwon Beack et al. 945 Object-based audio coding can provide new music applications with interactivity. To efficiently compress a lot of target audio objects, a subband-based parametric coding scheme has been adopted for MPEG spatial audio object coding. In this letter, the time-frequency (T/F) subband analysis structure is investigated. A reconfigured T/F structure is also proposed ...

Socially anxious individuals are characterized by an attentional bias for threat-related information. However, this attentional bias to threat may be attenuated [Behav. Res. Ther. 34 (1996) 945] when these individuals are anxious. In the present study, we attempted to increase subjects' Stroop interference by changing the frequency of words to nonwords. We hypothesized that when the ratio of wo...

Breakthroughs in microscopy technology provide new insights into cell biology. Early microscopes allowed Robert Hooke to see cells. Improved staining techniques enabled Camillo Golgi to see the apparatus that bears his name, and Robert Feulgen to visualize DNA in chromosomes. Similarly, EM allowed Keith Porter to visualize the endomembrane system. More recently, transgenic technology using fluo...

2014 We report 1H and 77Se-NMR data on oriented single crystals which establish the magnetic character of the semi-metallic ground state stabilized under high magnetic field in (TMTSF)2ClO4. A similar magnetic state can be stabilized at low temperature in the absence of magnetic field by non-magnetic molecular disorder. At low temperature the spin-lattice relaxation rate does not follow the Kor...

The entomopathogen Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) can colonize plants endophytically and stimulate the production of secondary plant metabolites with anti-herbivore activities. We assayed topical virulence B. to Aphis gossypii Glover (Hemiptera: Aphididae), effects cucumber inoculation this fungus on metabolites, physiological consequences for aphids that fed these ...
