Real-time optical intensity correlation using photorefractive BSO
Real-time optical intensity correlation using a photorefractive BSO crystal and a liquid crystal television is implemented. The underlying physics basis is considered, some specific techniques to improve the operation are proposed, and several optical pattern recognition tasks are …

Cardiovascular adjustments to isometric contractions: The role of intensity of contraction, endurance time, and different muscle groups
… was designed to investigate the influence of the intensity of contraction, endurance time, and the contracting muscle group on the cardiovascular responses to static exercise. Three primary questions were addressed: (1) Are the cardiovascular responses to isometric contractions dependent on the …

Efficient localization in a dispersive waveguide : applications in terrestrial continental shelves and on Europa
… ocean waveguide from passive beam-time intensity data obtained after conventional plane-wave beamforming of acoustic array measurements. The method is advantageous over existing source localization methods, since (1) no knowledge of the environment is required except that the …

Exploring Metallic Flavor Perception: Analysis of Human Salivary Proteins and the Use of the Iron-Binding Protein Lactoferrin in Reducing Metallic Off-Flavors
… saliva, and EDTA (36 ?M), a synthetic chelator. Time-intensity (TI) evaluation (n=6, 4 female; age 40-70) of lingering metallic flavor indicated that metallic flavor decreased with a post-rinse adjuvant treatment of lactoferrin as indicated by a reduced maximum intensity and area under the curve …

Could global warming affect space weather? : case studies of intense ionospheric plasma turbulence associated with natural heat sources
… and filaments/quasi-periodic echoes on the range-time-intensity (RTI) plots of radar measurements. Detailed analyses of radar, airglow, and GPS data allow us to determine the drift velocity/direction, the orientation/geometry, and the scale lengths of these plasma turbulence structures. They are …

Investigation of Offset Analgesia during Acute Central Sensitization, Opioid Administration and Complex Regional Pain Syndrome
… is multi-dimensional including aspects of intensity, quality, unpleasantness, as well as spatial and temporal distribution. The temporal processing of nociceptive information, or the mechanisms supporting how pain is perceived across the timeframe of a stimulus, is one aspect of pain that …

Long-term monitoring of vegetation dynamics in the Goegap Nature Reserve, Namaqualand, South Africa
… a definite environmental driving force, with the time, intensity and duration of importance, specifically to the annual species composition. Overall, the veld condition improved and continuous monitoring of the line transects on a regular basis should take place to improve our understanding of the …

Cache Characterization and Performance Studies Using Locality Surfaces
… One drawback to the locality surface is the time intensity of the stack-based algorithm. We provide a new parallel algorithm that reduces the computation time significantly. With this improvement, the locality surface becomes a viable and valuable tool for characterizing workloads and caches, …

Formation of Copper-Salivary Component Complexes and Its Effect on Sensory Perception
… of copper. A recent study suggested that intensity of copper taste may be dependent on the amount of solubilized copper, which increases at lower pH. This research was performed to identify 1) the temporal sensory characteristics of copper; 2) the effect of pH on perception of copper …

The effect of pH and ethanol on the astringent sub-qualities of red wine, and the implications for optimum grape maturity /
… were used to train the panel and measure the intensity of these attributes. It was found that decreasing pH values (averaged across all ethanol concentrations) showed an increase in the overall astringency of the wine. The combined treatments of ethanol and pH, real wine parameters (pH 3.4 and …

Relating structural properties to saltiness perception of model lipoproteic gels
… saltines and textural properties of the SLCs. A time-intensity (TI) method was used to evaluate the temporal saltiness perception properties of the SLCs. The saltiness of the SLCs correlated positively with the porosity, but did not correlate with the Rg,f. The increased saltiness with increasing …
