The behavior of steel structures subjected to seismic actions depends directly on the connections behavior. There are two current tendencies for ensuring the structural ductility: allowing the formation of plastic hinges in the beams by using reduced beam sections or reduced web sections or by ensuring the plastic hinge formation in the connection by using dissipative elements. This paper prese...

In modern offshore installations, thin walled columns are used for energy absorption in accident situation. When this advanced offshore shock absorber is subjected to axial compressive load, plastic hinges are developed on the sides of column and the column crushes with repeatable patterns. It can absorb considerable impact energy due to large and continuous plastic deformation. This paper deve...

Blasting demolition plays an important role in building demolition, and numerical-simulation methods can facilitate the optimization of blasting-demolition schemes. To study influence delay-time differences between columns on blasting effect small-aspect-ratio reinforced concrete structures, a separated common node model structures was established through finite element numerical simulation sof...

T cells of tumor bearers often show defective TCR-mediated signaling events and, therefore, exhibit impaired immune responses. As such, patients with heavy tumor burden are often not amenable to adoptive T cell therapy. To overcome this limitation, we have developed a chimeric receptor that joins an extracellular single chain Fv (scFv) of a specific Ab for Ag recognition to an intracellular pro...
