Abstract We evaluate the seismic performance of modern seismically designed wood light-frame (WLF) buildings, considering regional hazard characteristics that influence ground motion duration and frequency content and, thus, risk. Results show WLF building response correlates strongly with spectral shape but weakly duration. Due to flatter motions from subduction events, buildings at sites affe...

– We present a simple model of a vibrated box of sand, and discuss its dynamics in terms of two parameters reflecting static and dynamic disorder respectively. The fluidised, intermediate and frozen (‘glassy’) dynamical regimes are extensively probed by analysing the response of the packing fraction to steady, as well as cyclic, shaking, and indicators of the onset of glassy behaviour are analy...

The simultaneous control of the hindlimb paw-shake response and hindlimb walking at slow treadmill speeds (0.2-0.4 m/s) was examined in adult cats spinalized at the T12 level, 3-6 mo earlier. Paw shaking was elicited by either 1) application of adhesive tape or 2) water to the right hindpaw. To assess intralimb and interlimb coordination of the combined behaviors, activity from selected flexor ...

If C is a compact subset of R and H is a halfspace bounded by a hyperplane π, the set C̃ obtained by shaking C on π is defined as the set contained in H, such that for every line ` orthogonal to π, C̃ ∩ ` is a segment of the same length as C ∩ `, and one of its endpoints is on π. It is shown that there exist d + 1 hyperplanes such that every compact set can be reduced to a simplex, via repeated s...

OBJECTIVE Horizontal head shaking at 2 to 3 Hz can induce nystagmus in patients with central as well as in patients with peripheral vestibulopathy. However, the characteristics and diagnostic value of this post-head-shaking nystagmus (HSN) have not been studied systematically in central vestibulopathy, and little is known of the mechanisms involved. METHODS We analyzed spontaneous and HSN and...

BACKGROUND To estimate the prevalence of shaking and smothering and to determine risk factors in a population-based sample of mothers with 4-month-old infants in Japan. METHODS We administered a questionnaire to women who participated in a 4-month health checkup program in Aichi Prefecture, Japan (n = 6487; valid response rate, 66.8%), and assessed frequency of shaking and smothering during t...

In the present study, the possibility of concentrating tungsten-copper vein ore in South Chah-Palang was examined using gravity separators including Jig Machine (-2360+600 μm), shaking table (-600+120 μm), and multi-gravity separator (MGS) (-120 μm). The representative sample contains 1.5% WO3 and 5.95% CuO. The main tungsten minerals were ferberite and wolframite and their appropriate liberati...
