In recent years, seismic design of structures has been undergoing significant changes due to increasing demand for optimization and minimizing the level of damage and reducing the cost of structural repairs. Development of analytical methods and remarkable improvements of computer performance have been among the factors which influenced the design of structures. A lot of research has been condu...

In this prospective, multiinstitutional analysis of medial collateral ligament sprains in college football players, we categorized 987 previously uninjured study subjects according to frequency of wearing preventive knee braces, studied the patterns by which 47 of 100 injuries occurred to unbraced knees, and identified several extrinsic, sport-specific risk factors shared for both braced and un...

This study presents the status and results from an effort to design, fabricate, and test an adaptive jet engine chevron concept based upon embedding shape memory alloy (SMA) actuators in a composite laminate, termed a SMA hybrid composite (SMAHC). The approach for fabricating the adaptive SMAHC chevrons involves embedding prestrained Nitinol actuators on one side of the mid-plane of the composi...

Chevron mixing devices are used to reduce noise from commercial separate-flow turbofan engines. Mechanical chevron serrations at the nozzle trailing edge generate axial vorticity that enhances jet plume mixing and consequently reduces far-field noise. “Fluidic chevrons” generated with air injected near the nozzle trailing edge create a vorticity field similar to that of the mechanical chevrons ...

BACKGROUND Little information is available regarding the ankle braces orthopaedic sports medicine clinicians recommend or clinicians' concerns that may influence their decisions to recommend use of an ankle brace. HYPOTHESES (1) Clinicians most frequently recommend lace-up braces with straps. (2) Clinicians who are concerned about potential adverse side effects from ankle brace use are less l...

The Lyon Bracing Management evolved since 1947 as cooperation between Pierre Stagnara MD and Bouillat & Terrier CPO. The Lyon management results of a reduction with a plaster cast from one to four months, before moulding the brace. It is a below arm adjustable brace without any superstructure. Very early braces were made from a combination of steel and leather. After the second world war, Pierr...

Lateral ankle sprains are one of the most common injuries incurred in recreational and competitive athletics. These injuries have a significant impact in terms of cost, athletic participation, and activities of daily living. Prophylactic ankle braces are often used to reduce the risk of injury recurrence when individuals return to athletic participation. The purpose of this clinical commentary ...

Local-nonlocal coupling is an organizational principle in protein folding. It envisions a cooperative energetic interplay between local conformational preferences and favorable nonlocal contacts. Previous theoretical studies by our group showed that two classes of native-centric coarse-grained models can capture the experimentally observed high degrees of protein folding cooperativity and diver...

We administered the revised Assessment of Qualitative and Structural Dimensions of Object Representations (Blatt, Chevron, Quinlan, Schaffer, & Wein, 1992) to 279 male and female undergraduate students and carried out independent principal components analyses of maternal and paternal ratings. Three stable factors, Agency, Communion, and Structure, were found in both sets of ratings. This factor...
