Mechanoelectrical transduction of acoustic signals is the fundamental process for hearing in all ears across the animal kingdom. Here, we performed in vivo laser-vibrometric and electrophysiological measurements at the transduction site in an insect ear (Mecopoda elongata) to relate the biomechanical tonotopy along the hearing organ to the frequency tuning of the corresponding sensory cells. Ou...

In this issue of Neuron, Sehadova et al. show that synchronization of circadian clocks in the brains of Drosophila by daily temperature changes requires chordotonal organs, mechanosensory structures that function as stretch receptors in insects. This is strikingly different from the more direct path by which brain clocks perceive light.

Recent developments in the area of memory management have focused on reducing the eeects of the disk latency problem. These developments include the use of a compressed cache and the utilisation of memory on remote hosts. Further developments in the areas of Quality of Service (QoS) provision and user-level virtual memory have provided the impetus for a more spe-cialised run-time environment th...

CONTEXT Some researchers have suggested that an alteration of stretch perception could be responsible for the success of the contract-relax (CR) stretch, a stretch technique derived from proprioceptive neuromuscular facilitation (PNF). OBJECTIVE This study was conducted to determine if the alteration of the stretch perception is a possible explanation for the range of motion (ROM) gains of th...

of stretch Am. J. Physiol. 204(s) : 433-438. 1963.-A comparative study was made of effects of stretch on cat papillary muscle and auricle strips, hamster ventricular wall, ground squirrel ventricular strip, chicken auricle and ventricle, terrapin auricle and ventricle strips, and carp ventricle. In all species mild stretch increased contractile tension, excessive stretch decreased it, and veloc...

Cold stretch-formability and stretch-flangeability of 0.2%C-1.5%Si-5.0%Mn (in mass%) martensite-type medium Mn steel were investigated for automotive applications. High obtained in the subjected to an isothermal transformation process at temperatures between Ms Mf − 100 °C. Both formabilities decreased compared with those 0.2%C-1.5%Si-1.5Mn -3Mn steels (equivalent TRIP-aided martensitic steels)...
