Seismic and Post-Seismic Ductility and Forces of Mid-Story Pin Moment-Resisting Frames Based on Scale of Local Deformation of I-Beam’s Segments

Applied Mechanics
A mid-story pin system to avoid moment-resisting frame column failure during seismic action was proposed recently. The solution consists of a reinforced concrete (RC) pier protruding from the foundations, the steel column connected with the ...

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

Molecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Mechanical properties and damage analysis of SiCf/SiC and SiCf/SiC-EBC composites in high-temperature combustion gas environment

Journal of Aeronautical Materials
Silicon carbide fiber-reinforced silicon carbide ceramic matrix composites（SiCf/SiC） used in aero-engines are damaged or even failed due to the oxidation and corrosion by high-temperature and high-speed combustion gases.

Thermal shock resistance behavior of a functionally graded ceramic: Effects of finite cooling rate

Theoretical and Applied Mechanics Letters, 2014
This work presents a semi-analytical model to explore the effects of cooling rate on the thermal shock resistance behavior of a functionally graded ceramic (FGC) plate with a periodic array of edge cracks.

The effect of impact damage and circular holes on the compressive strength of a graphite-epoxy laminate [PDF]

Specimens were impacted by 1.27-cm-diameter aluminum spheres with speeds ranging from 52 to 101 m/s. Some specimens were impacted without any applied compressive load and then loaded to failure to determine their residual strength.

Beta decay and shape isomerism in 74Kr

, 1998
We study the properties of $^{74}$Kr, and particularly the Gamow Teller strength distribution, using a deformed selfconsistent HF+RPA method with Skyrme type interactions.
