The predatory labial strike of dragonfly (Aeschna) larvae could be elicited by an artificial water jet stimulus. The larvae showed fair prey-catching ability even when visually deprived, whereas when deprived of mechanosensory and visual information, the ability decreased sharply. Also, immobilized prey were unable to elicit a strike even from intact larvae. The percentage of labial strike (PLS...

Running performance, energy requirements and musculoskeletal stresses are directly related to the action-reaction forces between the limb and the ground. For human runners, the force-time patterns from individual footfalls can vary considerably across speed, foot-strike and footwear conditions. Here, we used four human footfalls with distinctly different vertical force-time waveform patterns to...

Advances in imaging technology and computer-assisted design (CAD) have recently enabled the introduction of patient-specific knee implant designs that hold the potential to improve functional performance on the basis of patient-specific geometries, namely a patient-specific sagittal and coronal curvature, as well as enhanced bone preservation. The objective of this study was to investigate the ...

Blowfly strike of sheep can be represented as part of the fly life cycle (Fig-1). Our objective is to identify and quantify important factors promoting progression through the cycle so as to be able to predict the timing and impact of one particular part of the cycle viz. the development of fly larvae on sheep or 'strike'. In Fig-l, some of the factors believed to be important for the developme...

To survive, organisms must avoid predation and acquire nutrients and energy. Sensory systems must correctly differentiate between potential predators and prey, and elicit behaviours that adjust distances accordingly. For snakes, strikes can serve both purposes. Vipers are thought to have the fastest strikes among snakes. However, strike performance has been measured in very few species, especia...

Electric power utilities face increasing demand for service reliability. Since cloud-toground lightning strikes are among the most frequent yet least understood causes of service interruption, predicting the geographical and temporal distribution of the lightning strikes can help power system planners and designers improve the protection of new and existing transmission lines. Lightning is the ...

Both speakers and students await tabulation o f the vote on one o f the strike proposals presented at last n ight’s strike hearing. By Dave Lammers Rich Smith Bill Carter In a tum ultou . and confusing rally in the Stepan Center last night, striking students voted to extend the strike un til Friday, May 15, so that Notre Dame students and faculty can con tinue to oppose President N ixon’s polic...

By using the recent experimental measurements of B → ππ and B → Kπ branching ratios, we find that factorization is unable to reproduce the observed BRs even taking into account the uncertainties of the input parameters. Charming and GIM penguins allow to reconcile the theoretical predictions with the data. Because of these large effects, we conclude, however, that it is not possible, with the p...

This paper presents the first control algorithm for the innerand outer-strike point position for a Spherical Torus (ST) fusion experiment and the performance analysis of the controller. A liquid lithium divertor (LLD) will be installed on NSTX which is believed to provide better pumping than lithium coatings on carbon PFCs. The shape of the plasma dictates the pumping rate of the lithium by cha...
