Inconsistent terminology and variation in service models have made synthesis of the supported accommodation literature challenging. To overcome this, we developed a brief, categorical taxonomy that aimed to capture the defining features of different supported accommodation models: the simple taxonomy for supported accommodation (STAX-SA). Data from a previous review of existing classification s...

We have performed extended X-ray absorption fine structure (EXAFS) analysis for artificial Cr-goethite to elucidate the local structure around Cr in Cr-goethite. The spectra were obtained using synchrotron radiation X-rays at the Photon Factory in Tsukuba. The first shell contributions were isolated by Fourier filtering the EXAFS data, and the inverse Fourier transformed single-shell data were ...

The recently proposed methodology known as the analysis of domain-averaged Fermi holes was applied to reveal the nature and peculiarity of metal-metal bonding interactions in two recently reported complexes with an ultrashort, presumably quintuple Cr-Cr bond. The results of the analysis straightforwardly confirm the considerable reduction of the Cr-Cr bond order resulting from depletion of the ...

Identity-based proxy re-signature (IDPRS) is a novel cryptographic primitive that allows a semi-trusted proxy to convert a signature under one identity into another signature under another identity on the same message by using a re-signature key. Due to this transformation function, IDPRS is very useful in constructing privacy-preserving schemes for various information systems. Key revocation f...

We asked how a new, complex trait evolves by selecting for diurnal oscillations in the budding yeast, Saccharomyces cerevisiae. We expressed yellow fluorescent protein (YFP) from a yeast promoter and selected for a regular alternation between low and high fluorescence over a 24-hr period. This selection produced changes in cell adhesion rather than YFP expression: clonal populations oscillated ...

Recently, we reported the structures of the duocarmycins1'2*, a unique antitumor antibiotics constituted with two structural moieties, a substituted pyrroloquinoline or its chemical equivalent cyclopropanopyrroloindole and a trimethoxyindolylcarbonyl group3). In this communication we wish to report the structure ofduocarmycin SA (1), a stable compound structurally related to the duocarmycin A (...

Equipment operators play an integral role in the safe and efficiency operation of heavy equipment. They observe the environment, understand the situation, and make decisions and actions accordingly. Compared with other types of equipment, operating a crane is more sophisticated and mentally demanding, and thus crane operators are more vulnerable to human errors. Therefore, special consideration...
