In practice, a GPS receiver must first replicate the PRN code that is transmitted by the SV being acquired by the receiver; then it must shift the phase of the replica code until it correlates with the SV PRN code. When cross-correlating the transmitted PRN code with a replica code, the same correlation properties occur that occurs for the mathematical autocorrelation process for a given PRN co...

An analysis of the mean three-dimensional horizontal circulation in the subtropical South Atlantic based on velocity fields derived primarily from Argo data and AVISO sea surface heights, collected in the years 2000–2012, provides new insight into the zonal and meridional transports in the subtropical gyre. The velocity fields reveal the reduction of the latitudinal extent of the subtropical gy...

The purpose of the current study was to investigate the effect of a high- intensity treadmill running (8 weeks) with or without aqueous extraction of black Crataegus-Pentaegyna (Siyah -Valik) on liver ABCA1 mRNA expression and plasma HDL-C, total, and direct bilirubin concentration in male rats. Twenty Wistar male rats (4-6 weeks old, 140-170 g weight) were used. Animals were randomly assigne...

Environmental factors including ionizing radiation and chemical agents have been known to be able to induce DNA rearrangements and cause genomic structural variations (SVs); however, the roles of intrinsic characteristics of the human genome, such as regional genome architecture, in SV formation and the potential mechanisms underlying genomic instability remain to be further elucidated. Recentl...

The psychometric properties of the Italian version of the Coping Inventory for Stressful Situations-Short Version (CISS-SV-21 items) were tested. In a group of 1,291 hospital-based nurses (77.8% women), four alternative factor models of the CISS-SV were tested using confirmatory factor analysis (CFA). The four models were: M1, the original CISS-SV-21 items three-factor model corresponding to th...

At early stages of differentiation neurons already contain many of the components necessary for synaptic transmission. However, in order to establish fully functional synapses, both the pre- and postsynaptic partners must undergo a process of maturation. At the presynaptic level, synaptic vesicles (SVs) must acquire the highly specialized complement of proteins, which make them competent for ef...

We developed a framework of analysis to predict the stroke volume (SV) resulting from the complex mechanical interaction between the ventricle and its arterial system. In this analysis, we characterized both the left ventricle and the arterial system by their end systolic pressure (Ps)-SV relationships and predicted SV from the intersection of the two relationship lines. The final output of the...

Central nerve terminals release neurotransmitter in response to a wide variety of stimuli. Because maintenance of neurotransmitter release is dependent on the continual supply of synaptic vesicles (SVs), nerve terminals possess an array of endocytosis modes to retrieve and recycle SV membrane and proteins. During mild stimulation conditions, single SV retrieval modes such as clathrin-mediated e...

Determining the layered structure of the earth demands the solution of a variety of inverse problems; in the case of electromagnetic soundings at low induction numbers, the problem is linear, for the measurements may be represented as a linear functional of the electrical conductivity distribution. In this paper, an application of the support vector (SV) regression technique to the inversion of...

Meridional velocity, mass, and heat transport in the equatorial oceans are difficult to estimate because of the nonapplicability of the geostrophic balance. For this purpose a steady-state model is utilized in the equatorial Indian Ocean using NCEP wind stress and temperature and salinity data from the World Ocean Atlas 2005 (WOA05) and Argo. The results show a Somali Current flowing to the sou...
