Cipher-policy attribute-based encryption (CP-ABE) is a more efficient and flexible encryption system as the encryptor can control the access structure when encrypting a message. In this paper, we propose a privacy-preserving decentralized CP-ABE (PPDCP-ABE) scheme where the central authority is not required, namely each authority can work independently without the cooperation to initialize the ...

BACKGROUND The ATP7A gene encodes the ATP7A protein, which is a trans-Golgi network copper transporter expressed in the brain and other organs. Mutations in this gene cause disorders of copper metabolism, such as Menkes disease. Here we describe the novel and unusual mutation (p.T1048I) in the ATP7A gene of a child with Menkes disease. The mutation affects a conserved DKTGT1048 phosphorylation ...

ERGIOVANNI and Starratt pose a fundamental question that is basic to the ends, means, and outcomes of educa tion: Should schools use people to accom plish organizational ends or should people use schools to accomplish human ends? They ask the reader to recall, "the countless times he found no reason or no record of origin for a particular policy, act, or way of behaving in the schools of his ex...

The authority of a leader is enhanced when her commands or recommendations for action are obeyed. The authority of a leader is also enhanced when her commands are "principled" based on good reasons and therefore the leader is seen to be acting in the interests of her followers. But for a leader interested in maintaining her authority, there is often a con ict between these strategies. For examp...

Both the amino-terminal and carboxyl-terminal domains of IGF binding protein (IGFBP)-3 are believed to contribute to high-affinity IGF binding. To investigate cooperativity in IGF binding by these domains, we expressed IGFBP-3 fragments 1-88 (NBP-3) and 185-264 (CBP-3) as FLAG and hexahistidine-tagged fusion proteins, respectively. IGF-I and IGF-II bound to NBP-3 poorly and to CBP-3 with modera...
