Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...

This paper aims to empirically evaluate the extent to which the 1986 Semiconductor Trade Arrangement (STA) affected the Japanese producers’ behavior and thus the evolution of the markets for the 256K and the 1M Dynamic Random Access Memory (DRAM) chips. We find that overall the STA facilitated the collusive behavior of the Japanese producers even beyond the myopic optimization: during the STA p...

OBJECTIVE Previous studies have indicated that statin therapy may promote plaque regression. However, the impact of statin therapy on plaque composition has not been clearly elucidated. We performed a meta-analysis to investigate the effect of statin therapy on coronary plaque composition as assessed by virtual histology intravascular ultrasound (VH-IVUS). METHODS Online databases were search...

We report new results for the second edition of the MICCAI DTI tractography challenge. We build upon a new model, termed Diffusion Directions Imaging, that describes the random motion of water molecules in fibrous tissues and we utilize it as an input to a multifiber deterministic tractography algorithm. We apply the method to track the corticospinal tract in two patients suffering from tumors ...

Introduction: Electromagnetic radiofrequency (RF) sources are widely used to heat up cutaneous and subcutaneous tissues for different applications, such as, generation of new dermal collagen and denaturation of adipocytes or fat cells. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells [1]; however, it is common...

due to business and environmental issues, the efficient design of an integrated forward/reverse logistics network has recently attracted more attention from researchers. the significance of transportation cost and customer satisfaction spurs an interest in developing a flexible network design model with different delivery paths. this paper proposes a flexible mixed-integer programming model to ...
