Physiological characteristics of first order horizontal canal neurons , especially the relationship between their spontaneous activity and response to angular acceleration were studied in 20 albino guinea pigs. The average resting ISI was 48.9ms and this was clearly lower than that in pigmented guinea pigs. The neurons differentiated into three groups according to their CV values. These called ...

In the near future, laser-plasma particle accelerators will be able to sustain electric fields in excess of 100 GeV/m, along plasma channels several Rayleigh lengths long. For these extreme conditions, present day laser wakefield diagnostics such as Frequency Domain Interferometry will not be able to resolve the wake field structure and determine the magnitude of the electric field. In this pap...

Recent improvements to the QZ algorithm for solving generalized eigenvalue problems are summarized. Among the major modifications are novel multishift QZ iterations based on chasing chains of tiny bulges and an extension of the so called aggressive early deflation strategy. The former modification aims to improve the execution time of the QZ algorithm on modern computing systems without changin...

Dynamically reconfigurable architectures offer the opportunity to migrate software into hardware functional units at runtime. Architectures derived from the AMIDAR model exhibit such possibilities. In previous work we have shown how to identify heavily used code sequences and have also shown that it might be interesting to synthesize hardware for a set of methods of one class and also cache the...

This paper presents the acceleration sensitivity and the resulting vibration-induced phase noise of an electrostatically coupled encapsulated silicon microresonator. External vibrations can produce phase noise in microresonators by generating time-varying stress in the resonant beams. A spring mounted resonator design that reduces the induced axial stress is presented here. Measurements and sim...

Temporal coding is studied with an oscillatory network model that is a complex-valued generalization of the Cohen-Grossberg-Hopfield system. The model is considered with synchronization and acceleration, where acceleration refers to a mechanism that causes the units of the network to oscillate with higher-phase velocity in case of stronger and/or more coherent input. Applying Hebbian memory, we...

It is shown how laboratory experiments performed with high intensity femtosecond lasers can probe the physics of black holes in the near-horizon regime. The acceleration generated by the high intensity laser ranging from 10g to more than 10g is identified with the gravitational acceleration at stretched horizons. In the black-hole’s asymptotic region, the stretchedhorizon-reflected light shows ...

Slow finger movements in man are not smooth, but are characterized by 8- to 12-Hz discontinuities in finger acceleration thought to have a central source. We trained two macaque monkeys to track a moving target by performing index finger flexion/extension movements and recorded local field potentials (LFPs) and spike activity from the primary motor cortex (M1); some cells were identified as pyr...
