We discuss the requirements for laser systems used in Coherent Anti-Stokes Raman Scattering (CARS) microscopy and particularly in its wide-field modification. While such laser parameters as wavelength, spectral width and frequency difference between pump and Stokes beams are similar for all CARS systems, requirements for pulse energy, repetition rate, pulse length and mode structure might be si...
INTRODUCTION Some car rental companies in California and other states in the USA have established non-smoking policies for their vehicles. This study examined the effectiveness of these policies in maintaining smoke-free rental cars. METHODS A stratified random sample of 250 cars (non-smoker, smoker and unknown designation) was examined in San Diego County, California, USA. Dust, surfaces and...
Molecular contrast in optical coherence tomography (OCT) is demonstrated by use of coherent anti-Stokes Raman scattering (CARS) for molecular sensitivity. Femtosecond laser pulses are focused into a sample by use of a low-numerical-aperture lens to generate CARS photons, and the backreflected CARS signal is interferometrically measured. With the chemical selectivity provided by CARS and the adv...
The purpose of this study was to evaluate scores generated from the Autism Treatment Evaluation Checklist (ATEC), a parent-rated measure, and those derived from professionally completed Childhood Autism Rating Scale (CARS) evaluations. A cohort of 56 participants diagnosed with an autism spectrum disorder was used for the study, and each child was evaluated independently by the parent using the...
Objective: Computerized training for cognitive enhancement is of great public interest, however, there is inconsistent evidence for the transfer of training gains to every day activity. Several large trials have focused on speed of processing (SOP) training with some promising findings for long-term effects on daily activity, but no immediate transfer to other cognitive tests. Here, we examine ...
The ENCOAL Corporation has shipped, to two utility customers, over, 500 rail cars (six partial trains and two full trains) of solid product’(PDF) from its plant located at Triton Coal Company’s Buckskin Mine near Gillette Wyoming. Shipments span a range of blends from 15% to essentially unblended PDF. Utility handling of these shipments is comparable to that of run-of-mine Buckskin coal. Result...
For the vehicle detection and tracking in the roundabouts, several difficulties have to be faced, e.g. the use of non nadiral perspectives, vehicle images overlapping and radiometric differences between top and side of the cars; the silhouette of the cars is, besides, not regular and the size is variable. In the paper, the upgrade of a procedure for detecting and tracking vehicles in a roundabo...
Coherent anti-Stokes Raman scattering (CARS) microscopy permits vibrational imaging with high-sensitivity, high speed, and three-dimensional spatial resolution. We review recent advances in CARS microscopy, including experimental design, theoretical understanding of contrast mechanisms, and applications to chemical and biological systems. We also review the development of multiplex CARS microsp...
African American motorists in the United States are more likely than white motorists to have their cars searched by police checking for illegal drugs and other contraband. The courts are faced with the task of deciding on the basis of tra¢c-stop data whether police are basing their decisions to stop cars on the race of the driver. We develop a model of law enforcement for a population with two ...
Vision-based driver assistance in modern cars has to perform automated real-time understanding or modeling of traffic environments based on multiple sensor inputs, using ‘normal’ or specialized (such as night vision) stereo cameras as default input devices. Distance measurement, lane-departure warning, traffic sign recognition, or trajectory calculation are examples of current developments in t...
