Building structures are subject to displacement under the influence of forces resulting from earthquake. The most common method of controlling such displacements in steel structures, which are usually of lateral type, is the use of braces. Depending on designing requirements and feasibility, braces are available in various forms. Configuration of bracing systems is generally of concentric or ec...

p53 is inactivated and degraded by the E6 protein encoded by the integrated human papillomavirus (HPV) in the cervical cancers (Scheffner et al., 1990). The susceptibility of p53 to degradation by the E6 protein varies between the arginine and proline variants at codon 72 of p53 (Storey et al., 1998). In vivo studies demonstrate that the arginine p53 variant is seven times more susceptible to d...

Photoinhibition of macroalgae in the epilithic algal community (EAC) of coral reefs was studied using chlorophyll fluorescence techniques at One Tree Island, Great Barrier Reef, Australia. F jFm (variable to maximum fluorescence darkened samples) of shallow macroalgae declined by 50% on fine summer and winte~ days, reco.vering i~ late afternoon. Within a species, thalh from low-hght habItats we...

The mammalian acrosome reaction (AR) is the fusion, at multiple points, of the outer acrosomal membrane with the overlying plasma membrane. This fusion causes the release of acrosomal contents and the exposure of the inner acrosomal membrane. The time taken for this process to occur is not accurately known. Estimates for AR in mouse spermatozoa vary from ;2 minutes after stimulation with solubi...

This study is a conceptual replication of previous work by Storey, Stern, & Parker (1990) that examined the influence of participation in integrated vs. segregated recreation/sports activities on evaluations of a person with mental retardation by persons without a disability. The Storey et al., (1990) study observed that people with mental retardation were viewed less favorably when participati...

To identify physical parameters of a large structural system, the computational challenges in dealing with a large number of unknowns are formidable. A divide-and-conquer approach is often required to partition the structural system into many substructures, each with much lesser unknowns for more accurate and efficient identification. Furthermore, in view of the ill-conditioned nature of invers...

This study is investigated the optimum parameters for a tuned mass damper (TMD) under the seismic excitation. Shuffled complex evolution (SCE) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a TMD. The efficiency of the TMD is evaluated by decreasing the structural displacement dynamic magnification factor (DDMF) and acceleration ...

A neural-network-based post-earthquake damage identification methodology for smart structures with the direct use of vibration measurements is developed. Two neural networks are constructed to facilitate the process of post-earthquake damage identification. The rationality of the proposed methodology is explained and the theory basis for the construction of an emulator neural network (ENN) and ...

Infills can highly influence the seismic response of a Reinforced Concrete (RC) building: generally speaking, their presence leads to an increase in global stiffness and strength, but their brittle behavior can result in an increase of displacement demand if a certain threshold of seismic intensity is overcome. Moreover, presence of infills often leads to a change in the collapse mechanism comp...

A two-stage stepup procedure is defined and an explicit formula for the FDR of this procedure is derived under any distributional setting. Sets of critical values are determined that provide a control of the FDR of a two-stage stepup procedure under iid mixture model. A class of two-stage FDR procedures modifying the Benjamini–Hochberg (BH) procedure and containing the one given in Storey et al...
