A comprehensive investigation of the surfaces of copper through silicon vias Cu-TSVs and gold stud bumps is presented. These vias and stud bumps were bonded at room temperature using a nanobonding and interconnection equipment. The influence of heating on the bonded interface was also studied. In order to achieve an intimate contact between the Au-stud bumps and Cu-TSVs, the stud bumps were fla...

Herpesvirus proteases belong to a new class of serine proteases and contain a novel Ser-His-His catalytic triad, while classical serine proteases have an acidic residue as the third member. To gain a better understanding of the molecular basis for the functional role of the third-member His residue, we have carried out structural and biochemical investigations of human cytomegalovirus (HCMV) pr...

A study of architectural walls for energy dissipation and vibration control of buildings in seismic zones is presented. Typical architectural walls exhibit inelastic behavior; however, both the stiiness and energy dissipation capacity degrade after the walls are damaged. Integrating passive damping devices within these walls augments their energy dissipative abilities by widening the hysteresis...

BDNF (Brain derived neurotrophic factor) is a secretion protein and a member of the neurotrophin family of growth factors. Structural and functional characterization of BDNF Varanus komodoensis is of interest while its structure remains unknown. Thus, a homology molecular model of BDNF was constructed for gleaning possible structural insights. The model was compared with the structure of the ho...

The effects of a number of design parameters have been investigated including the types of cavity insulation, resilient channels, gypsum board thickness, the number of gypsum board layers, stud arrangements, and type of framing. The results have shown that the main factors that affected the performance of stud wall assemblies were the type of insulation and the number of gypsum board layers. In...
