A new recombination operator, called Gene Pool Recombination (GPR) is introduced. In GPR, the genes are randomly picked from the gene pool defined by the selected parents. The mathematical analysis of GPR is easier than for two-parent recombination (TPR) normally used in genetic algorithms. There are n difference equations for the marginal gene frequencies that describe the evolution of a popul...

A 30 m by 30 m two-dimensional grid was designed on a flat bench behind a quarry face of predominantly limestone with thin shale layers located at a Bonner Springs, Kansas site to test the utility of ground-penetrating radar (GPR) for stratigraphic studies. GPR data were collected along seven lines parallel to the quarry face and seven lines perpendicular to the quarry face, each separated by 5...

In natural speech, for a given speaker, vocal tract length (VTL) is effectively fixed whereas glottal pulse rate (GPR) is varied to indicate prosodic distinctions. This suggests that VTL will be a more reliable cue for identifying a speaker than GPR. It also suggests that listeners will accept larger changes in GPR before perceiving speaker change. We measured the effect of GPR and VTL on the p...

AIM To investigate the value of the gamma-glutamyltraspeptidase (GGT)-to-platelet (PLT) ratio (GPR) in the diagnosis of hepatic fibrosis in patients with chronic hepatitis B (CHB). METHODS We included 390 untreated CHB patients in this study. The GPR, aspartate aminotransferase (AST)-to-PLT ratio index (APRI), and fibrosis-4 (FIB-4) of all patients were analysed to determine if these paramete...

To date, a number of numerical methods, including the popular Finite-Difference Time Domain (FDTD) technique, have been proposed to simulate Ground-Penetrating Radar (GPR) responses. Despite having a number of advantages, the finite-difference method also has pitfalls such as being very time consuming in simulating the most common case of media with high dielectric permittivity, causing the for...

Ground penetrating radar (GPR) has been widely used in geologic, hydrogeologic, and civil engineering purposes. Correlated with geological exposures and trenches, GPR data can offer detail subsurface information to past earthquakes investigation. McClymont et al. [2][3] show very good performance of GPR for fault characterization. In this paper, we show an example of practical application of GP...

Ground Penetrating Radar (GPR) is an effective and practical geophysical imaging tool, with a wide set of applications in geological mapping of subsurface information. This research study aims at determination of the geophysical parameter differences in the subsurface geological structures and construction of a 3D fracture model. GPR and resistivity methods were applied to detect the unstable t...

Ground-penetrating radar (GPR) is one of the most commonly used instruments to map Snow Water Equivalent (SWE) in mountainous regions. However, some areas may be difficult or dangerous access; besides, surveys can quite time-consuming. We test a new system fulfill need speed up acquisition process for analysis SWE and access remote areas. A GPR antenna (900 MHz) mounted on drone prototype desig...

G-protein signaling plays important roles in asymmetric cell division. In C. elegans embryos, homologs of receptor-independent G protein activators, GPR-1 and GPR-2 (GPR-1/2), function together with Galpha (GOA-1 and GPA-16) to generate asymmetric spindle pole elongation during divisions in the P lineage. Although Galpha is uniformly localized at the cell cortex, the cortical localization of GP...

The gpr gene, which codes for the protease that initiates degradation of small, acid-soluble proteins during spore germination, has been cloned from Bacillus megaterium and Bacillus subtilis, and its nucleotide sequence has been determined. Use of a translational gpr-lacZ fusion showed that the B. subtilis gpr gene was expressed primarily, if not exclusively, in the forespore compartment of the...
