Background Age-related gait changes may play a critical role in functional limitations of older
adults. Despite sizable interest in determining how age alters walking mechanics, small …

Predictive simulation based on dynamic optimization using musculoskeletal models is a
powerful approach for studying human gait. Predictive musculoskeletal simulation may be used …

Measuring responses in the proteome to various perturbations improves our understanding
of biological systems. The value of information gained from such studies is directly …

This book is the result of a symposium held in Salt Lake City, Utah, on 8-10 Dec. 1969. The
aspects dealt with are: sugar beet as a food resource; environmental factors; seedbed …

In this paper we study linear differential systems (1) x′ = A ̃ (θ + ωt)x, where A ̃ (θ) is an (n
× n) matrix-valued function defined on the k-torus T k and (θ, t) → θ + ωt is a given irrational …

… Drought during the MCA is evident across much of eastern Africa (Russell and Johnson,
2005), but our finding of drought from AD 1400 to 1750 stands in contrast to previous studies …

<p>This paper examines the <bold>jihadist</bold> threat and its implications for the global
war on terrorism (GWOT)—a threat noted for its commitment, determination, innovation, and …

Like proteins, structured RNAs must specify a native conformation that is more stable than all
other possible conformations. Local structure is much more stable for RNA than for protein, …

High-resolution analyses of the elemental composition of calcite and biogenic silica (BSi)
content in piston cores from Lake Edward, equatorial Africa, document complex interactions …

Large amounts of intracellular periodic acid-Schiff positive protein, closely resembling Russell
bodies tinctorially and histochemically and, to varying degrees, morphologically, were …
