Treadmill walking is a convenient tool for studying the human gait; however, a common gait parameter, stride length, can be difficult to calculate directly because relevant reference points continually move backwards. Although there is no direct calculation of stride length itself, we can use positional heel-marker data to directly determine a similar parameter, step length, and we can sum two ...

Corridors may mitigate the adverse effects of habitat fragmentation by restoring or maintaining connectivity between disjunct populations. The efficacy of corridors for large carnivores, however has rarely been evaluated objectively. We used noninvasive sampling, microsatellite analysis, and population assignment tests to evaluate the effectiveness of a regional corridor in connecting two Flori...

We propose a two-stage classifier for the elastic bunch graph matching based recognition of facial expressions. The major purpose is to calculate distinctive similarity between image patterns by applying optimal weights to responses from different Gabor kernels and those from different fiducial points. In the first stage, we perform SVM on each fiducial point individually to extract a weighted ...

To optimize the labeling and visualization of PCR products we tested different variables, including deoxynucleotide concentration and ratio, dilution of labeled product, number of PCR cycles, and use of one-step or nested labeling protocols. Labeling was achieved using a fixed amount of labeled dATP, whose relative specific activity was varied by adding increasing amounts of cold dATP. Optimal ...

We examined the effects of inbreeding on the performance of wood frog (Rana sylvatica) larvae in the field and in the laboratory. We used microsatellite analysis to establish the parentage and degree of inbreeding of the larvae. Two different estimators of inbreeding were used. The first was based on average multilocus heterozygosity, and the second was based on a molecular relatedness estimato...

Electromagnetic (EM) tracking has been recognized as a valuable tool for locating the interventional devices in procedures such as lung and liver biopsy or ablation. The advantage of this technology is its real-time connection to the 3D volumetric roadmap, i.e. CT, of a patient’s anatomy while the intervention is performed. EM-based guidance requires tracking of the tip of the interventional de...

Single-nucleotide polymorphisms (SNPs) are rapidly replacing microsatellites as the markers of choice for genetic linkage studies and many other studies of human pedigrees. Here, we describe an efficient approach for modeling linkage disequilibrium (LD) between markers during multipoint analysis of human pedigrees. Using a gene-counting algorithm suitable for pedigree data, our approach enables...

Precise investigation of genetic diversity by means of novel molecular tools has made it possible to identify the superior genotypes among various male and female pistachio populations. Cytogenetic studies have shed light on the possible presence of distinct sex chromosomes in male and female genotypes. In this study, 22 start codon targeted (SCoT) primers were used to investigate the genetic d...
