It is important to precisely know the whole time history of various types of fault slip events to understand the physics of earthquake generation. We develop a new time dependent inversion method for imaging transient fault slips from geodetic data. Past studies employed a linear Gaussian state space model and applied Kalman filter. The Kalman filter based methods, however, do not allow any var...

We study the voltage noise properties including the statistics of phase-slips and switching rates in moderately damped Josephson junctions by using a novel efficient numerical approach that combines the matrix continuedfraction method with the full counting statistics. By analyzing the noise results obtained for the resistively and capacitively shunted junction (RCSJ) model we identify differen...

We investigate the transition route to phase synchronization in a chaotic laser with external modulation. Such a transition is characterized by the presence of a regime of periodic phase synchronization, in which phase slips occur with maximal coherence in the phase difference between output signal and external modulation. We provide the first experimental evidence of such a regime and demonstr...

Background Unnoticed user slips may contribute to adverse events, but medical devices can be designed to help detect and block some slips, thus enabling the user to take corrective action. Obviously different designs achieve this with greater or lesser success [1]. This paper shows how comparison of alternative design features for a “5-key” user interface (figure 1) can help reduce number entry...

We demonstrate the role of the proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport characteristics of micron-size superconducting quantum interference devices with a well-controlled geometry, we obtain a complete picture of the different thermal regimes. These determine whether or not the junctions a...

We have developed an in vivo tribometer for characterizing the friction of a human heel against a planar test surface. The pedestrian steps down on an angled test surface and an observer determines if the person's heel slips. In the simplest variation, the subject simply steps down onto the test surface. The second variation has the standing subject's lower leg constrained to a vertically runni...

Stroke is a devastating event which can result in permanent disability. Due to the lack of treatments available for use after stroke, compounds which work to limit cell loss, reduce behavioral deficits, and enhance recovery of function are needed. The isoflavone daidzein has been demonstrated to be neuroprotective when fed to rats beginning prior to stroke. Herein, we tested whether subcutaneou...

Network synchronization is a generic concept that depicts a way of distributing common time and frequency references to all the nodes of a network, to align their respective time and frequency scales (Box B). The role of network synchronization, especially in the context of frequency accuracy, has grown in importance since the late 1970s, when digital transmission and switching were introduced....

In the current study we examined an associative learning mechanism by which food cues (signaling low- versus high-calorie food) can bias instrumental responses directed toward those foods. To investigate the clinical relevance of this mechanism, we used a computerized Pavlovian-to-instrumental transfer task and compared performance of 19 severely obese individuals to that of 19 healthy-weight c...

This study investigated the lower extremity preventive measures for slips on simulated slippery surfaces in construction worksites. A total of 15 harnessed Chinese males walked without slips on a 5-m walkway in 16 simulated conditions 10 times at their natural cadence. Joint moments were calculated from kinetics, kinematics and anthropometric data recorded from a force plate, a Novel Pedar syst...
