Abstract. A model of two incompressible, Newtonian fluids coupled across a common interface is studied. The nonlinearity of the coupling condition exacerbates the problem of decoupling the fluid calculations in each subdomain, a natural parallelization strategy employed in current climate models. A specialized partitioned time stepping method is studied which decouples the discrete fluid equati...

We present a formulation of rigid body dynamics with frictional contact that leverages ideas from discrete mechanics to derive time-stepping schemes with any desired order of integration accuracy. By utilizing the new time-stepping methods as dynamics constraints in a direct trajectory optimization scheme, we are able to perform contact-implicit trajectory optimization with accuracy equal to tr...

Background: Pseudomonas aeruginosa (P. aeruginosa) is a ubiquitous bacterium which can be found in most moisture places such as soil, water, food, plants, and animals including humans. Due to genetic flexibility among strains, there is no standard molecular identification for P. from different sources, particularly human colonizing or commensal isolates. Materials Method: Monoplex PCR usin...

PURPOSE The authors have previously demonstrated that wounding of human corneal epithelial cells (HCECs) transactivates epidermal growth factor (EGF) receptor (EGFR) and its downstream signaling pathways and that this EGFR signaling is required for epithelial wound healing. In this study, the authors sought to identify the underlying mechanisms for EGFR transactivation in response to wounding i...

Stepping On is a community-based intervention that has been shown in a randomized controlled trial to reduce fall risk. The Wisconsin Institute for Healthy Aging adapted Stepping On for use in the United States and developed a training infrastructure to enable dissemination. The purpose of this study is to: (1) describe the personal characteristics of Stepping On participants; (2) quantify part...

there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...

When reaching for an object that unexpectedly moves, the hand is 'magnetically' drawn toward the object. This occurs even before the subject perceives object motion [1–3], possibly through sub-cortical visuo-motor processes [4]. Whether a similar process exists for the lower limb is open to question. The evolution of a rapid visuo-motor process has obvious advantages for the hand, for example f...
