We evaluated the effects of slow-rate atrial pacing on impulse formation of the sinus node in 13 isolated rabbit right atria using the microelectrode technique. After the spread of activation was mapped to determine true sinoatrial conduction time (SACT) (38 ± 16 msec [± SD]), the atrium was paced for eight beats at constant intervals slightly shorter than spontaneous cycle length in steps of 1...

Many handheld force-feedback devices have been proposed to provide a rich experience with mobile devices. However, previously reported devices have been unable to generate both constant and translational force. They can only generate transient rotational force since they use a change in angular momentum. Here, we exploit the nonlinearity of human perception to generate both constant and transla...

In on-line robot trajectory generation, a connecting polynomial is normally used to remove discontinuities in velocity and acceleration between adjacent path segments. This paper presents a new technique for performing such transitions in which adjacent path segments are “blended” together, with excess acceleration being removed using an estimate of the initial path velocities. Since this metho...

The aim of this study was to measure high-resolution strain fields in planar sections of brain tissue during translational acceleration to obtain validation data for numerical simulations. Slices were made from fresh, porcine brain tissue, and contained both grey and white matter as well as the complex folding structure of the cortex. The brain slices were immersed in artificial cerebrospinal f...

A new simple convergence acceleration method is proposed for a certain wide range class of convergent alternating series. The method has some common features with Smith’s and Ford’s modification of Levin’s and Weniger’s sequence transformations, but it leads to less computational and memory cost. The similarities and differences between all three methods are analyzed and some common theoretical...

1 SUMMARY In this project, we add a limited subset of staged functions to the Spatial hardware accelerator design language. This support includes implementation of language support for staged functions, analyses for optimizing performance and area, and generating synthesizable implementations of these staged functions. We evaluate these additions by comparing the runtime and area of a set of be...

In a modern three-dimensional integrated circuit (3D IC), vertically stacked dies are interconnected using through silicon vias. 3D ICs are subject to undesirable temperature-cycling phenomena such as through silicon via protrusion as well as void formation and growth. These cycling effects that occur during early life result in opens, resistive opens, and stress induced carrier mobility reduct...
