Based on the design concept of earthquake-resilient structure, a new-type box-shaped steel piers with embedded energy-dissipating plates was proposed. Quasi-static tests 6 pier specimens under variable axial pressure and cyclic horizontal loading were carried out. By analyzing failure mode, load-displacement hysteretic curve, skeleton displacement ductility coefficient, stiffness degradation ch...

In reality, humans are always exposed to a combination of toxic substances and seldom to a single agent. Simultaneous exposure to a multitude of chemicals could result in unexpected consequences. The combined risk may lead to greater or less than a simple summation of the effects induced by chemicals given individually. Here, a method is proposed for estimating the cumulative risk which is the ...

This paper computes some potential employment and income effects of microelectronic-based technical change (MTC) in Canada. The probable upper and lower bounds of the predicted outcomes are determined by simulating alternative scenarios, and by computing the range of feasible post technical change transition paths for each scenario. The occupational shifts required to accommodate the technical ...

Goossens, H.H.L.M. and A. J. Van Opstal. Dynamic ensemble coding of saccades in the monkey superior colliculus. J Neurophysiol 95: 2326–2341, 2006. First published December 21, 2005; doi:10.1152/jn.00889.2005. The deeper layers of the midbrain superior colliculus (SC) contain a topographic motor map in which a localized population of cells is recruited for each saccade, but how the brain stem d...

A deep earthquake swarm in late 2003 at Lake Tahoe, California (Richter magnitude < 2.2; depth of 29 to 33 kilometers), was coeval with a transient displacement of 6 millimeters horizontally outward from the swarm and 8 millimeters upward measured at global positioning system station Slide Mountain (SLID) 18 kilometers to the northeast. During the first 23 days of the swarm, hypocentral depths ...

conclusions extremity injuries especially open fractures of lower limbs account for the majority of hospitalized victims. compartment syndrome is one of the main problems that should be addressed. our study demonstrates that people still need more education regarding earthquakes and the government should direct more attention to this issue. results in this study, there were 105 females (52.5%) ...

The deeper layers of the midbrain superior colliculus (SC) contain a topographic motor map in which a localized population of cells is recruited for each saccade, but how the brain stem decodes the dynamic SC output is unclear. Here we analyze saccade-related responses in the monkey SC to test a new dynamic ensemble-coding model, which proposes that each spike from each saccade-related SC neuro...

Conventional techniques in elastography estimate strain as the gradient of the displacement estimates obtained through crosscorrelation of pre- and postcompression rf A-lines. In these techniques, the displacements are estimated over overlapping windows and the strains are estimated as the gradient of the displacement estimates over adjacent windows. The large amount ofnoise at high window over...

PURPOSE To investigate the respiratory motion of metal clips or surgical staples placed in the gastric wall for planning of radiation therapy in gastric cancer patients. METHODS This study examined 15 metal markers in the gastric walls of 12 patients with gastric cancer treated with external-beam photon RT. Motion assessment was analyzed in 41 respiratory phases covering 20 s acquired with co...
