Seat height that is too high (> 120% of lower leg length [LLL]) or too low (< 80% of LLL) can impede safe transfer and result in falls. This study examines the difference between LLL of frail nursing home residents and the height of their toilets and beds in the lowest position, compares the patient or environmental characteristics of those able to transfer from the bed or toilet to those who c...

OBJECT Falls are the most common accident scenario in young children as well as the most common history provided in child abuse cases. Understanding the biomechanics of falls provides clinicians with objective data to aid in their diagnosis of accidental or inflicted trauma. The objective of this study was to determine impact forces and angular accelerations associated with low-height falls in ...

We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with a reduced refractive index (which acts as a potential barrier), such that in the middle region it splits a waveguide into two weakly coupled parts. It is predicted by numerical simulations and analytical consideratio...

10 Abstract Performing any behavior requires perceiving 11 affordances—whether and how that behavior can be per12 formed. Perception of affordances exhibits action scaling— 13 choices about when to transition between two different modes 14 of behavior reflect the fit between action capabilities and en15 vironmental properties. The boundary between distances that 16 are perceived to be reachable...

In this note we present global string solutions which are a generalization of the usual field theory global vortices when the kinetic term is DBI. Such vortices can result from the spontaneous symmetry breaking in the potential felt by a D3-brane. In a previous paper (hep-th/0706.0485), the DBI instanton solution was constructed which develops a ”wrinkle” for stringy heights of the potential. A...

An analytically tractable model is introduced which exhibits both, a glass– like freezing transition, and a collection of double–well configurations in its zero– temperature potential energy landscape. The latter are generally believed to be responsible for the anomalous low–temperature properties of glass-like and amorphous systems via a tunneling mechanism that allows particles to move back a...

Plant height (PH) is a complex trait regulated by the environment and multiple genes. PH directly affects crop yield, harvest index, lodging resistance. From plant dwarf mutants, many genes related to have been identified described. Nonetheless, molecular mechanism of regulation in high-culm rice mutants has not well studied. By using transcriptome weighted gene co-expression network analysis (...

height is amongst the most delicate subjects of geodesy. thanks to the global navigation satellite systems (gnss) like gps or glonass, 3d point positioning of points, by geometrical positioning, since years ago has become a common practice. the height derived from these ways has a geometrical concept. in civil projects the physical concept of the height is more demanded. orthometric height, , i...
