Contact sounds can provide information for material perception, and according to previous studies decay seems to be one of the most important cues. This information can be used to tune a physical model to represent various materials. This work deals with a specific class of contact sounds, i.e. collision sounds. A hammer-resonator physical model is developed, and subjective experiments are perf...

OBJECTIVE In March 2007, we investigated a cluster of Nipah encephalitis to identify risk factors for Nipah infection in Bangladesh. METHODS We defined confirmed Nipah cases by the presence of IgM and IgG antibodies against Nipah virus in serum. Case-patients, who resided in the same village during the outbreak period but died before serum could be collected, were classified as probable cases...

Haptic rendering involving deformable objects has seen many applications, from surgical simulation and training, to virtual prototyping, to teleoperation, etc. High quality rendering demands both physical fidelity and real-time performance, which are often conflicting requirements. In this paper, we simulate contact force between a held rigid body and an elastic object and the corresponding sha...

in this paper, stability analysis of walking gaits and robustness analysis are developed for a five-link and four-actuator biped robot. stability conditions are derived by studying unactuated dynamics and using the poincarã© map associated with periodic walking gaits. a stable gait is designed by an optimization process satisfying physical constraints and stability conditions. also, considering...

The formation of microtubule-derived structures is thought to involve nucleation in all directions and stabilization of microtubules that contact relevant targets. A recent study indicates, during mitosis, there may be a third step, in which microtubule growth is directed over long distances without physical contact between the target and microtubules.

The spread of disease through a physical-contact network and the spread of information about the disease on a communication network are two intimately related dynamical processes. We investigate the asymmetrical interplay between the two types of spreading dynamics, each occurring on its own layer, by focusing on the two fundamental quantities underlying any spreading process: epidemic threshol...

BACKGROUND Behavioural lifestyle interventions can be effective at promoting initial weight loss and supporting physical activity and dietary behaviour change, however maintaining improvements in these outcomes is often more difficult to achieve. Extending intervention contact to reinforce learnt behavioural skills has been shown to improve maintenance of behaviour change and weight loss. This ...

Contact resistances of bonded copper interconnects in threedimensional integration technology under different bonding conditions are investigated by using a novel test structure. A reduction in specific contact resistance is obtained by longer anneal time. The specific contact resistance of bonded interconnects with longer anneal time does not change with the interconnect sizes. Underlying phys...

Chromosomes are the physical realization of genetic information and thus form the basis for its readout and propagation. Here we present a high-resolution chromosomal contact map derived from a modified genome-wide chromosome conformation capture approach applied to Drosophila embryonic nuclei. The data show that the entire genome is linearly partitioned into well-demarcated physical domains th...
