A new statistical test for randomness, the strict avalanche criterion (SAC) test, is presented, together with its results over some well-known generators in the literature. These results are analyzed and some possible applications of the test, as for measuring the strength of cryptographic primitives including block ciphers, stream ciphers and pseudorandom number generators, especially during t...

To provide an effective method of green aquaculture, the photocatalysts CuO/ZrO2/CB/coal-tar-pitch-SAC, which have visible light sterilization capacity, were successfully fabricated by coating ZrO2 and CuO on surface CB/coal-tar-pitch-SAC. The structures synthesized CuO/ZrO2/CB/coal-tar-pitch-SAC investigated XRD, XPS SEM measurements in detail. It was observed that materials possess obvious he...

A 65-year-old man presented in Beira Central Hospital, Mozambique, with a right scrotal mass (diameter 80 x 80 cm), evolved over 15 years. The patient could barely move, and his weight at admission was 142 kg (Fig 1A and 1B). History of previous diseases was unremarkable, his general condition was good, and he had normal vital parameters. Physical examination showed wrinkled and thickened scrot...

OBJECTIVE Na(+) and Cl(-) are dominant ions in the endolymphatic fluid in the endolymphatic sac and are important for volume regulation in the endolymphatic sac. An epithelial sodium channel (ENaC) and other Na(+) transporters have been identified in the endolymphatic sac epithelia, and they are involved in the regulation of endolymph. Although the presence of Cl(-) channels in the endolymphati...

A new statistical test for randomness, the SAC test, is presented, together with its results over some well-known generators in the literature. These results are analyzed and some possible applications of the test, as for measuring the strength of cryptographic primitives including block ciphers, stream ciphers and pseudorandom number generators, especially during the design and analysis phase,...

cAMP is an evolutionary conserved, prototypic second messenger regulating numerous cellular functions. In mammals, cAMP is synthesized by one of 10 homologous adenylyl cyclases (ACs): nine transmembrane enzymes and one soluble AC (sAC). Among these, only sAC is directly activated by bicarbonate (HCO3(-)); it thereby serves as a cellular sensor for HCO3(-), carbon dioxide (CO2), and pH in physio...
