Launch of new series: bright spots, physical activity investments that work

Work-Related physical activity and coronary diseases

Introduction: Prevalence of cardiovascular disease (CVD) is increasing in the world. Modernization and reduction of physical activity in present century and also controversial results about relationship between work-related physical activity and CVD, lead to investigate the relationship between work-related physical activity and CVD. Methods: This cross-sectional study is based on data from f...

Bright spots of sustainable shark fishing

Sharks, rays and chimeras (class Chondrichthyes; herein 'sharks') today face possibly the largest crisis of their 420 million year history. Tens of millions of sharks are caught and traded internationally each year, many populations are overfished to the point where global catch peaked in 2003, and a quarter of species have an elevated risk of extinction [1-3]. To some, the solution is to simpl...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Sample-space bright spots removal using density estimation

Rendering images using Monte-Carlo estimation is prone to bright spots artefacts. Bright spots correspond to high intensity pixels that appear when a very low probability sample outweighs all other sample contributions. We present an average estimator that is robust to outliers, which detects and removes samples that are considered as outliers, and lead to bright spots in images computed using ...
