It is shown that for a collection of n classical harmonic oscillators, the long-time distribution of potential energies P is approximated by sinm(πP) for n⩾4, where m=(8n/π2−1/√2) and P is scaled to lie between 0 and 1. As n→∞, the distri

A home electrocardiography (ECG) and blood pressure (BP) monitoring network was established in Beijing. The network consisted of three parts: (1) the home ECG and BP monitoring devices; (2) the monitoring centre at the hospital; and (3) the data comm

Benzyl radicals are often regarded as being inert, and not capable of initiating chain reactions. However, during the preignition phase in a diesel engine, the benzylperoxy radical, formed by the addition of O{sub 2} to the benzyl radical can be pres

Classical trajectory calculations on the methyl isocyanide molecule at energies above 25,000 cm−1 confirm that the rate of reaction to methyl cyanide is bimodal, with a very fast rate before 0.1 ps, and a slower rate from then on. We conclude that

Trajectory calculations simulating the interaction of a classical plane electro magnetic wave with a highly rotationally excited ethane molecule in a quasi bound state are reported. The internal motions of the molecule are markedly changed within

Trajectory calculations suggest that, at energies above twice the critical energy for reaction, molecular rotation and molecular vibration generally make equal contributions to the specfic rate constant k(E) for the unimolecular isomerization of CH 3

The moment of inertia of CH3NC about the z axis is very small, and the rotational spacings for increasing quantum number K are large. In the T-shaped transition state for isomerization to CH3CN, on the other hand, both the N and C atoms lie off the a

This article discusses a cost-effective portable home unit for electrocardiogram (ECG) and blood pressure (BP) monitoring. Based on feedback from our previous work concerning a PC-based ECG/BP telemonitoring system, the system described helps to over
