Recent court decisions in the United States, Canada, and the United Kingdom have demonstrated confusion and uncertainty by the triers of fact, whether they be judges or juries, about the evidence presented in cases of alleged abusive head trauma. It is not surprising that judges and juries have a difficult time understanding and evaluating the evidence presented by the opposing sides of these c...

– 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...

Eight patients are described with an unusual form of carotid transient ischemic attack, limb shaking. The basic features included a brief, involuntary, coarse, irregular, wavering movement or tremble involving arm-hand alone, or arm-hand and leg together. In 2 patients limb shaking was the initial manifestation of carotid occlusive disease, and all but one patient had other typical carotid tran...

Plantlets under in vitro conditions transferred to ex vivo conditions are exposed to biotic and abiotic stresses. Furthermore, in vitro regenerated plants are typically frail and sometimes difficult to handle subsequently increasing their risk to damage and disease; hence acclimatization of these plantlets is the most important step in tissue culture techniques. An experiment was conducted unde...

Design charts for seismic pressures against rigid walls subjected to horizontal earthquake shaking are presented for both uniform and nonuniform backfills. Solutions are based on a simplified model of soil response which gives results that agree almost exactly with rigorous solutions. Peak seismic thrusts are presented for three different soil profiles. For each profile, 250 combinations of gro...

In this, the second of a two-part paper, the analysis of the apparent frequency of a seven-story reinforced-concrete hotel building in Van Nuys, Calif., is extended to consider its time-dependent changes, both short and long term. The instantaneous apparent frequency is measured by two methods: windowed Fourier analysis and zero-crossings analysis. The results show that it changes from earthqua...

Abstract With the aim of investigating effect water depth on earthquake response a deep-water cable-stayed bridge tower, this study designed and manufactured large-scale tower model, taking across deep reservoir hydropower station as reference. Under boundary conditions similar to reference, shaking table tests were conducted reflect structural under white noise actions at different depths. The...

The concentration of enterotoxin B secreted by four strains of Staphylococcus aureus was dependent upon the shaking speed. For the conditions established, each strain demonstrated an optimal shaking speed, and speeds in excess of the optimum resulted in decreased secretion of toxin. At the optimal shaking speed, maximum secretion occurred at 37 C. At 45 C, both growth and toxin secretion were a...

We report a case of an otherwise healthy 23-month-old boy who presented with nystagmus, head shaking, andabnormal posture suggestive spasmus nutans. Neuro-ophthalmologic exam revealed bilateral, low-amplitude, high-frequency, horizontal, disconjugate nystagmus that was more prominent in one eye along shaking and tilt or face turn. The rest the systemic physical examination were normal. Magnetic...

We study the circular shaking of a two dimensional optical lattice, which is essentially (2+1) space-time lattice exhibiting periodicities in both spatial and temporal dimensions. The near-resonant considered here dynamically couples low-lying $s$ band first excited $p$ bands by transferring photon frequency. intertwined symmetries are further uncovered to elucidate degeneracy spectrum solved w...
