BACKGROUND Concerns have been raised about findings of associations between particulate matter (PM) air pollution and mortality that have been based on a single "best" model arising from a model selection procedure, because such a strategy may ignore model uncertainty inherently involved in searching through a set of candidate models to find the best model. Model averaging has been proposed as ...

Methods: After contaminating a boot with pig manure, the examiner either stepped through a boot bath of 1% Virkon®S; stood in a boot bath of 1% Virkon®S for 2 minutes; scrubbed the boot for 30 seconds in a boot bath of 1% Virkon®S; or scrubbed the boot for 30 seconds in a water bath and then stepped through a boot bath of 1% Virkon®S. Untreated, contaminated boots, and boots scrubbed for 30 sec...

In the study, the influence of different boot prototype stiffness on gait kinematics and kinetics was investigated. The boot stiffness was determined by force-deformation measurement while pressing the foot model inserted into the boot by a custom-made robot. Gait analysis was carried out in nine neurologically intact subjects during walking while wearing two different boots with and without ca...

Evaluation of new educational methods traditionally uses randomly selected treatment and control groups. However, if it is believed that a new method is effective then it may be desirable to allow anyone who wants to participate to do so (i.e., to not withhold the new “treatment” from possibly deserving students). This complicates evaluation of the effectiveness of the new method. We evaluate t...

The present work is concerned with the design of an innovative ski-boot. In order to optimize ergonomics and biomechanical behavior of the ski-boot it is important to take into account the orientation of the leg with respect to the ground. The SGS system (Stance Geometry System) developed in this work allows the skier to adjust for posture in the frontal plane by rotating the sole of the boot a...

Current efforts to increase the security of the boot sequence for mobile devices fall into two main categories: (i) secure boot: where each stage in the boot sequence is evaluated, aborting the boot process if a non expected component attempts to be loaded; and (ii) trusted boot: where a log is maintained with the components that have been loaded in the boot process for later audit. The first a...
