Estimation of population density and investigation of socio-spatial organization of ocelots (Leopardus pardalis) from comparison and integration of two noninvasive methods
… Studying felids using traditional capture methods can be costly, labor intensive, or invasive. Telemetry studies yield the greatest level of information on behavior and ecology, however these methods require live capture that may cause stress and disturbance, or potentially injury or …

Leveraging Partial Identity Information in Spatial Capture-Recapture Studies with Applications to Remote Camera and Genetic Capture-Recapture Surveys
Noninvasive methods for monitoring wildlife species have revolutionized the way population parameters, such as population density and survival and recruitment rates, are estimated while accounting for imperfect detection using capture-recapture models. Reliable estimates of these parameters are …

Reproducibility and validity of two anaerobic threshold methodologies with overweight women
… to determine the reliability and validity of two noninvasive methods for determining anaerobic threshold (AT) and; to examine the effect of an aerobic training program on the AT. Twelve sedentary, overweight women participated in an 8 wk walk/jog program 3 dâ ¢wk⁻¹ at 70% VO<sub>2max</sub> with a …

Monitoring Bacteria Cultures Using Near Infrared (nir) Binary Spectronephelometry (bsn), Raman Spectra and Principal Component Analysis (pca)
<p>Current noninvasive methods cannot continuously and simultaneously monitor the concentrations of cells and media components that define the state of native bacterial cultures, because of changing turbidity. A new technique, binary spectronephelometry (BSN) has the same or better sensitivity and …

A Lattice Boltzmann method model of diffusion-weighted magnetic resonance imaging in skeletal muscle
… cellular microstructure of skeletal muscle with noninvasive methods is paramount in developing effective therapeutic procedures for the elderly, such as physical exercise. Using special proton magnetic resonance imaging (MRI) protocols we can investigate non-invasively diffusion phenomena within …
