Modeling Microscopic Driver Behavior under Variable Speed Limits: A Driving Simulator and Integrated MATLAB-VISSIM Study
Variable speed limits (VSL) are dynamic traffic management systems designed to increase the efficiency and safety of highways. While the macroscopic performance of VSL systems is well explored in the existing literature, there is a need to further understand the microscopic behavior of vehicles …

Statistically learned visual representations support visual working memory
Visual statistical learning (VSL) refers to the human ability to unintentionally extract statistical information from our environment. VSL has been proposed to have wide-reaching influence on a number of aspects of cognition. However, direct evidence that statistically learned information is used …

Probiotic Supplementation, The Gut Microbiota, and Cardiovascular Health
… males receiving the multi-strain probiotic, VSL #3 (or placebo), while a consuming a high fat diet for 4-weeks. First, we tested the hypothesis that VSL #3 would attenuate the rise in serum endotoxin and consequent arterial stiffening following high fat feeding in healthy, non-obese males. …

Implementation Strategies For Real-time Traffic Safety Improvements On Urban Freeways
… Among these strategies are Variable Speed Limit (VSL) and ramp metering. VSL are ITS devices that are commonly used to calm traffic in an attempt to relieve congestion and enhance throughput. With proper use, VSL can be more cost effective than adding more lanes. In addition to maximizing the …

The Effect of a Probiotic Supplement on Insulin Sensitivity and Skeletal Muscle Substrate Oxidation during High Fat Feeding
… was to determine the effects of the probiotic VSL#3 on body weightand composition, skeletal muscle substrate oxidation, and insulin sensitivity and during 4 weeks of high-fat, hypercaloric feeding. We hypothesized that the probiotic would attenuate the body weight and fat gain and adverse …

Do Probiotics Protect Against the Deleterious Effects of a High-Fat Diet?
… while receiving a daily oral gavage of water (C-VSL#3, HF-VSL#3) or probiotics (C+VSL#3, HF+VSL#3) equivalent to 1.2 billion live cultures. Changes in body weight, body composition, respiratory exchange ratio, energy expenditure, and glucose and insulin tolerance were measured in live mice. …

Information, decision-making and health
… is to determine the value of a statistical life (VSL) implicit in food consumption decisions and to compare this value with previous estimates of the VSL. The main positive result is that the VSL estimated from food consumption is about 1/10th as large as estimates from other contexts. I also …

Elementary Classroom Organization Delivery Model and Its Effect on Student Achievement
… academic performance on reading and mathematics VSL pass rates for fourth graders in Region II of Virginia. Analysis of variance (ANOVA) was used to test the hypothesis and results revealed that there is no evidence of a significant difference between the two classroom organizational models on …

Three essays on the impacts of income taxes
… estimation of the Value of a Statistical Life (VSL) parameter. When taxes change, the pre-tax wages of risky jobs should shift relative to the pre-tax wages of safe jobs in a manner proportional to the VSL. This strategy yields VSL estimates between $50 million and $75 million, an order of …

An object-oriented simulator for the visual simulation environment
… an object-oriented Visual Simulation Language (VSL) for specifying model logic. The Visual Simulator executes VSE models and displays the visual representation of the execution. It provides a class library used by modelers' VSL logic specification, and lets users collect statistics. Four major …

Benefits of Advanced Traffic Management Solutions: Before and After Crash Analysis for Deployment of a Variable Advisory Speed Limit System
<p>Variable speed limit (VSL) systems are important active traffic management tools that are being deployed across the U.S. and indeed around the world for relieving congestion and improving safety. Oregon’s first variable advisory speed limit signs were activated along Oregon Highway 217 in the …

Evaluating Ramp Metering And Variable Speed Limits To Reduce Crash Potential On Congested Freeways Using Micro-simulation
… at the metered on-ramps. Variable Speed Limits (VSL) were individually not as effective as ramp metering but when implemented along with ramp metering, they were found to further improve the safety on the freeway section under consideration. By means of a detailed experimental design it was …

Determination of the effects of caffeine C1, 3. 7- trimethylxanthine in Tris-based egg yolk extender and different incubation intervals on the quality of cryopreserved bull semen
… a decline in sperm velocity parameters (VCL, VSL, and VAP) over incubation time. In comparison, higher concentrations (5 and 8 mM) resulted in improved acrosome integrity but a faster decline in motility and an increase in tail abnormalities. Viability declined progressively in all treatments …
