Lightweight porous ceramic materials that can recover their shapes after mechanical deformation have numerous applications. However, these types of materials tend to be highly fragile and often crack when compressed. Here, we report on the fabrication and characterization of highly porous, freestanding composites of hexagonal boron nitride (h-BN) and single-walled carbon nanotubes (SWCNTs) of d...

We have analyzed the effects of gene activation on chromatin conformation throughout an approximately 170-kb region comprising the human fragile X locus, which includes a single expressed gene, FMR1 (fragile X mental retardation 1). We have applied three approaches: (i) chromosome conformation capture, which assesses relative interaction frequencies of chromatin segments; (ii) an extension of t...

Due to the explosive growth of Internet and the development of digital content designing and processing techniques, many valuable materials can be represented in digital forms for exhibition and access via Internet. Due to the characteristics of easy duplication and modification of digital contents, it is necessary to develop a variety of watermarking techniques for various protection purposes ...

Non-reversing relaxation enthalpies (∆H nr) at glass transitions T g (x) in the P x Ge x Se 1-2x ternary display a wide, sharp and deep global minimum (~0) in the 0.09 < x < 0.145 range, within which T g becomes thermally reversing. In the reversibility window these glasses are found not to age, in contrast to aging observed for fragile glass compositions outside the window. Thermal reversibili...

Avian song learning is an important model system for understanding vocal learning in humans and other animals. Laboratory studies indicate that social interactions are critical for song learning, but field observations show that territorial males are aggressive to intruders, raising the question of whether young birds are tolerated, much less tutored in the wild. We examined how adult song spar...

We describe a basic Geo-coding service encompassing a geo-parsing tool and integrated digital gazetteer service. The development of a geo-parser comes from the need to explicitly georeference large resource collections such as the Statistical Accounts of Scotland which currently only contain implicit georeferences in the form of placennames thus making such collections inherently geographically...
