BACKGROUND The conflict between the anatomist and biologist surgeons is exemplified by the debate about subtrochanteric hip fractures. Closed intramedullary nailing is biologically friendly but may result in prolonged procedures and malunion. By contrast, accurate anatomical open reduction may disturb the biological composition of the fracture environment.(More)
Kinesin-1 motor proteins walk parallel to the protofilament axes of microtubules as they step from one tubulin dimer to the next. Is protofilament tracking an inherent property of processive kinesin motors, like kinesin-1, and what are the structural determinants underlying protofilament tracking? To address these questions, we investigated the tracking(More)
This paper investigates on motion synchronization of a multiple axes system. Two different control strategies, a cross-coupling controller in feedback loop and a linear quadratic optimal controller, were used to synthesize the synchronization compensator with the cross-coupling dynamics among the axes. These two methods are corresponding to SISO and MIMO(More)
 We have developed a computer vision teaching module consisting of materials for two or three lectures and a final project for use in a CS1 programming course. The final project is to write an image processing program with applications in computer vision. The program will read in a two dimensional array of data from a file that represents a black and white(More)
In flies and humans, bitter chemicals are known to inhibit sugar detection, but the adaptive role of this inhibition is often overlooked. At best, this inhibition is described as contributing to the rejection of potentially toxic food, but no studies have addressed the relative importance of the direct pathway that involves activating bitter-sensitive cells(More)
Most animals possess taste receptors neurons detecting potentially noxious compounds. In humans, the ligands which activate these neurons define a sensory space called "bitter". By extension, this term has been used in animals and insects to define molecules which induce aversive responses. In this review, based on our observations carried out in(More)
We investigate the impact of home country institutions on the skill level of immigrants to the United States over 1988-1998. Specifically, we explore the hypothesis that institutions are multidimensional and that the different dimensions have conflicting impacts on the migration of skilled labor. Using an exploratory factor analysis on fifteen institutional(More)
Knowledge about the three-dimensional stepping of motor proteins on the surface of microtubules (MTs) as well as the torsional components in their power strokes can be inferred from longitudinal MT rotations in gliding motility assays. In previous studies, optical detection of these rotations relied on the tracking of rather large optical probes present on(More)
INTRODUCTION Clinical governance highlights risk management, clinical effectiveness and use of evidence based practice as key elements in the provision of a quality service. A change in the method of quality control in our orthopaedic trauma unit allowed us the opportunity to study if the quality of operative outcomes had changed as a result. The Hawthorne(More)
