An adaptive dwell scheduling algorithm for phased array radar (PAR) is proposed in this paper. The concept of online dynamic template introduced, based on which a general pulse interleaving technique PAR put forward. condition the novel more intuitive and general. traditional combined with results given. suitable tasks multiple repetition intervals (PRIs), can be utilized actual system. For pur...

The hypervariable region 1 (HVR-1) of the putative envelope encoding E2 region of hepatitis C virus (HCV) RNA was analyzed in sequential samples from three patients with acute type C hepatitis infected from different sources to address (i) the dynamics of intrahost HCV variability during the primary infection and (ii) the role of host selective pressure in driving viral genetic evolution. HVR-1...

Sequence evolution of the hypervariable region 1 (HVR1) in the N terminus of E2/NS1 of hepatitis C virus (HCV) was studied retrospectively in six chimpanzees inoculated with the same genotype 1b strain, containing a unique predominant HVR1 sequence. Immediately after inoculation, all animals contained the same HVR predominant sequence. Two animals developed an acute self-limiting infection. Ant...

Naked mole rats are among the most hypoxia-tolerant mammals identified and live in chronic hypoxia throughout their lives. The physiological mechanisms underlying this tolerance, however, are poorly understood. Most vertebrates hyperventilate in acute hypoxia and exhibit an enhanced hyperventilation following acclimatization to chronic sustained hypoxia (CSH). Conversely, naked mole rats do not...

As dogs have traveled with humans to every continent, they can potentially serve as an excellent proxy when studying human migration history. Past genetic studies into the origins of Native American dogs have used portions of the hypervariable region (HVR) of mitochondrial DNA (mtDNA) to indicate that prior to European contact the dogs of Native Americans originated in Eurasia. In this study, w...

There are suggestions that the phylogeny of Streptococcus mutans, a member of the human indigenous biota that is transmitted mostly mother to child, might parallel the evolutionary history of its human host. The relatedness and phylogeny of plasmid-containing strains of S. mutans were examined based on chromosomal DNA fingerprints (CDF), a hypervariable region (HVR) of a 5.6-kb plasmid, the rRN...

Ten healthy young males were studied with a double-blind, cross-over trial to determine whether or not chlormadinone acetate (CMA), a potent synthetic progesterone, augments hypoxic chemosensitivity. Seven days after CMA administration, inspiratory minute volume (VI) and tidal volume (VT) significantly increased. PaCO2 decreased by 3.0 +/- 2.6 (S.D.) Torr (p less than 0.05) and plasma bicarbona...

in this research a molecular method based on polymerase chain reaction for typing of clostridium perfringens was developed and toxin genotypes of 64 isolates from sheep and goats in iran were determined. the pcr assays were developed for detection of alpha (cpa), beta (cpb) and epsilon (etx) toxin genes, allowing classification of the isolates into genotypes a b, c and d. the field isolates ...

Abstract. Keyboard-typing tracking offers a convenient behavioral data collection method in web-based study settings. This paper investigated the feasibility of utilizing keyboard-typing for stress measurement. We present from two experiments: laboratory with N = 53 participants and an online 924 participants. In both studies, typed standardized text sequences during high-stress or low-stress c...

Chimpanzees are presently classified into three subspecies: Pan troglodytes verus from west Africa, P.t. troglodytes from central Africa, and P.t. schweinfurthii from east Africa. A fourth subspecies (P.t. vellerosus), from Cameroon and northern Nigeria, has been proposed. These taxonomic designations are based on geographical origins and are reflected in sequence variation in the first hyperva...
