The Influences of Heat Treatment on the Microstructure and Mechanical Properties of Rolled Ti2AlNb
In this study, the microstructural evolution, distribution, morphology, and change mechanism of an as-rolled Ti2AlNb alloy were quantitatively analyzed by X-ray diffraction and electron backscatter diffraction (EBSD). The results show that after solution

Improvement heat resistance and thermal stability of Mg-7Y-3Zn-0.4Mn alloy by Al/Ca element addition
Elevated temperatures lead to a reduction in the strength of magnesium-based alloys. At elevated temperatures (200–300 °C), even rare-earth reinforced Mg alloys experience notable strength deterioration.

ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Dynamic Light-Weight Groups [PDF]
The virtual synchrony model for group communication has proven to be a powerful paradigm for building distributed applications. In applications that use a large number of groups, significant performance gains can be attained if these groups share the resources required to provide virtual synchrony.
