Six independent mutations in the Caenorhabditis elegans spe-26 gene cause sterility in males and hermaphrodites by disrupting spermatogenesis. Spermatocytes in mutants with the most severe alleles fail to complete meiosis and do not form haploid spermatids. Instead, these spermatocytes arrest with missegregated chromosomes and mislocalized actin filaments,(More)
Caenorhabditis elegans spermatozoa move by crawling. Their motility requires thin cytoskeletal filaments assembled from a unique cytoskeletal protein, the major sperm protein (MSP). During normal sperm development the MSP is segregated to developing sperm by assembly into filaments that form a paracrystalline array in a transient organelle, the fibrous(More)
The future of human computer interaction systems lies in how intelligently these systems can take into account the user’s context. Research on recognizing the daily activities of people has progressed steadily, but little focus has been devoted to recognizing jointly activities as well as movements in a specific activity. For many applications such as(More)
—Today hospitals are equipped with many electronic transmitting devices, which results in electromagnetic interference that may impair wireless transmissions between medical devices. On the other hand, reliable and continuous collection via wireless communications of patient vital signs such as blood pressure and flow, core temperature, ECG, carbon dioxide(More)
—In Wireless Sensor Networks (WSNs), sensing nodes operate in dynamic environments resulting in neighboring nodes being discovered or lost at any moment causing the network topology to change constantly. Hence, routing schemes especially geographical ones (which use node positions to route data packets) require periodic exchange of control packets to(More)
Amylose precipitating factor, a lipoprotein, functions as a regulator of in vitro activity of glycogen/starch phosphorylase and of A/UDPglucose glucosyltransferase. The results suggest that this lipoprotein could act to stimulate the in vivo production by phosphorylase of long, linear glucans (amylose) from the short chain precursors. The lipoprotein also(More)
