Why are infants able to anticipate occlusion events and other people's actions but not the movement of self-propelled objects? This study investigated infant and adult anticipatory gaze shifts during observation of self-propelled objects and human goal-directed actions. Six-month-old infants anticipated self-propelled balls but not human actions. This demonstrates that different processes media...

Since 1956, the pMDI has become the most commonly prescribed and used aerosol device in the world. While concerns about global warming have led to a worldwide ban of CFCs, new HFA-propelled pMDIs are in development, requiring an evolutionary transition in the technology. The phase-out of CFC-propelled pMDIs has stimulated the development of more efficient DPIs, but issues such as cost of device...

aspartic proteases are a relatively small group of enzymes which express in various nematodes including onchocerca volvulus. an estimation of the gene copy number corresponding to the ov7a clone, which contains a cdna insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of o. volvulus, was made by slot blot analysis in a closely related species o. gibsonig...

We study experimentally and numerically a (quasi-)two-dimensional colloidal suspension of self-propelled spherical particles. The particles are carbon-coated Janus particles, which are propelled due to diffusiophoresis in a near-critical water-lutidine mixture. At low densities, we find that the driving stabilizes small clusters. At higher densities, the suspension undergoes a phase separation ...

OBJECTIVE To evaluate the controllability of, and physiological responses to, 2 newly designed unilaterally-propelled wheelchairs for patients with hemiplegia. DESIGN Within-subject comparison. SUBJECTS A total of 15 patients after stroke were recruited from the rehabilitation centre of Chung Shan Medical University, Taichung, Taiwan. METHODS Two newly designed wheelchairs (an ankle-prope...

introduction: the aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class ii composite resin restorations. methods: sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). class ii box-only cavities were prepared in distal aspects of each tooth with gingival margin located a...

Self-propelled colloids have emerged as a new class of active matter over the past decade. These are micrometer sized colloidal objects that transduce free energy from their surroundings and convert it to directed motion. The self-propelled colloids are in many ways, the synthetic analogues of biological self-propelled units such as algae or bacteria. Although they are propelled by very differe...
