A bstract We compute the normalization of multiple D-instanton amplitudes in type IIB string theory and show that result agrees with prediction S-duality due to Green Gutperle.

Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...

Diving into parenthood is never easy, but for common murres (Uria aalge) some positively prudent parenting is required. These birds have to decide whether they care more about the chicks they have got or about having additional chicks in the future. Anne Storey and her colleagues were able to measure the physiological tell-tale signs of this balancing act both when food is scarce and when food ...

High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...
