Hungry fruit flies can be trained by exposing them to two chemical odorants, one paired with the opportunity to feed on 1 M sucrose. On later testing, when given a choice between odorants the flies migrate specifically toward the sucrose-paired odor. This appetitively reinforced learning by the flies is similar in strength and character to previously(More)
The present study demonstrates that the primary somatosensory cortex of the rat contains a map of the entire body surface that is discernible with a routine anatomical staining technique, the succinic dehydrogenase reaction. The overall proportions of this map are relatively constant from rat to rat and very similar to those reported in previous(More)
We placed discrete injections of HRP into the somatosensory cortex of the rat on the day of birth and found discrete, ordered patterns of retrogradely labelled cells in the ventral posterior nucleus. We interpret these results as suggesting that topographic relations between thalamus and cortex develop independently of the periphery.
Conducted Energy Weapons (CEWs), such as those manufactured by TASER International Inc., are seeing increased use by law enforcement agencies as a less lethal force option; but, at the same time, these weapons are also seeing an increased level of concern in terms of their safety of use. In order to enable consistent evaluation of CEW performance, a(More)
— Conducted Energy Weapons (specifically the Taser) are being increasingly used by police in several countries, and have also been subject to significant media concern over the level of emissions and applicable safety standards. One issue has been the variability in electrical output between weapons, and of individual weapons over time. In order to address(More)
Development of reliable power-by-wire actuation systems for both aeronautical and space applications has been sought recently to eliminate hydraulic systems from aircraft and spacecraft and thus improve safety, efficiency, reliability, and maintainability. The Electrically Powered Actuation Design (EPAD) program was a joint effort between the Air Force,(More)
Right ventricular function plays an important role in determining cardiac symptoms and exercise capacity in chronic heart failure. It is known that right ventricle has complex anatomy and physiology. The purpose of this review paper is to demonstrate the best assessment of the right ventricle with current echocardiography. Echocardiography can assess(More)
