In some sense, argues Christopher Meyers in the lead article this, July-August 2021, issue of Hastings Center Report, to be a good ethicist is an activist. The question for ethicist, and Meyers, about how hard far push: much personal risk shoulder, tick off colleagues, institutional disruption create, look like angry protester. aiming at middle, two senses. time anger activism relentless, perva...

We examined conspicuous signalling displays in the context of predator-prey interactions. To determine in which context Puerto Rican crested anoles, Anolis cristatellusperform conspicuous signals, we exposed wild lizards to a model of a natural snake predator. The lizards gave six behavioural responses to the model: immobility, predator inspection, flight, lateral face-off, dewlapping and push-...

While a strategic imperative for financial institutions, major differences currently exist among banks' ability to convert their customers to using the internet. In addition, not a lot is known as to what drives those differences, although one can easily hypothesize that on-line banking adoption must be due to a combination of demand (“pull”) and firm (“push”) factors. This paper presents a sta...

ABSTRACT A broad objective of many lower extremity exoskeletons is to allow the wearer to expend less of their own energy for locomotion. Existing exoskeleton control algorithms are based on positive feedback. Forces are generated to augment movement initiated by the wearer. P...

Push back design as a complex task, is one of the major steps in the open pit mines planning. Push backs can be generated by varying economic factors such as commodity price, mining cost, processing cost, etc. Another important issue in generating push backs is grade uncertainty, which can cause the problem be more complex. Conventional methods of push back design ignore grade uncertainty. To o...

The purpose of the research is to investigate the energetic feature of the backpack load on soldier’s gait with variation of the trunk flexion angle. It is believed that the trunk flexion variation of the loaded gait may cause a significant difference in the energy cost which is often in practice in daily life. To this end, seven healthy Korea military personnel participated in the experiment a...

BACKGROUND The aim of this study was to find an objective graduation of pes equinus in infantile cerebral palsy, especially with regard to functional aspects, to allow a differentiated choice of the therapeutic options. Very often raises the question of whether a surgical lengthening of the Achilles tendon may let expect a functional improvement. METHODS For this documentation 17 patients wit...

The models of the foot available in the literature are either two- or three-dimensional (3-D), representing a part of the foot without considering different segments of bones, cartilages, ligaments, and important muscles. Hence, there is a need to develop a 3-D model with sufficient details. In this paper, a 3-D, two-arch model of the foot is developed, taking foot geometry from the X-rays of n...

For the impulsive ankle push-off (APO) observed in human walking two muscle-tendon-units (MTUs) spanning joint play an important role: Gastrocnemius (GAS) and Soleus (SOL). GAS SOL load Achilles tendon to store elastic energy during stance followed by a rapid release APO. We use neuromuscular simulation (NMS) bipedal robot investigate role of on optimize for robust gait then sequentially replac...
