LIM homeobox genes have a prominent role in the regulation of neuronal subtype identity and distinguish motor neuron subclasses in the embryonic spinal cord. We have investigated the role of Isl-class LIM homeodomain proteins in motor neuron diversification using mouse genetic methods. All spinal motor neuron subtypes initially express both Isl1 and Isl2, but Isl2 is rapidly downregulated by vi...

An accurate method to locate of the flexion-extension (F-E) axis and longitudinal rotation (LR) axis of the tibiofemoral joint is required to accurately characterize tibiofemoral kinematics. A method was recently developed to locate these axes using an instrumented spatial linkage (ISL) (2012, "On the Estimate of the Two Dominant Axes of the Knee Using an Instrumented Spatial Linkage," J. Appl....

It is generally believed genetic algorithm (GA) is superior to particle swarm optimization (PSO) while dealing with the discrete optimization problems. In this paper, a suitable mapping method is adopted and the modified PSO can effectively deal with the discrete optimization problems of linear array pattern synthesis. This strategy has been applied in thinned linear array pattern synthesis wit...

Matchedeld beamforming has been proposed for localizing wideband acoustic sources in uncertain underwater channels. While adaptive matchedeld beamforming provides adequate sidelobe suppression for stronger sources, at low signal-to-noise ratios it converges to its quiescent response, in this case the Bartlett beamformer, which has unacceptably high sidelobe levels. In this paper, a design metho...

This paper presents a prototype English-ToIndian Sign Language (henceforth called, ISL) machine translation system. The system can be used to disseminate information to more than 1.5 million deaf people in India. Further, considering such a low literacy rate among the deaf population in India [Vasishta, Woodward and Santis (1998)], the system can also be used as an educational tool to learn ISL.

polyphase is a common class of pulse compression waveforms in the radar systems. oppermann code is one of the used codes with polyphone pattern. after compression, this code has little tolerant against doppler shift in addition to its high side lobe level. this indicates that the use of oppermann code is an unsuitable scheme to radars applications. this paper shows that the use of amplitude wei...

BACKGROUND There is scientific evidence that preventive physical exercise is effective even in high age. In contrast, there are few opportunities of preventive exercise for highly aged people endangered by or actually in need of care. For example, they would not be able to easily go to training facilities; standard exercises may be too intensive and therefore be harmful to them; orientation dis...

Space–time adaptive processing (STAP) for airborne early warning radar has been a very active area of research since the late 1980’s. An airborne rectangular planar array antenna is usually configured into subarrays and then partial adaptive processing is applied to the outputs of these subarrays. In practice, three kinds of errors are often encountered, i.e., the array gain and phase errors ex...
