Abstract
The deformation of skis and the contact pressure between skis and snow are crucial factors for carved turns in alpine skiing. The purpose of the current study was to develop and to evaluate an optimization method to determine the bending and torsional stiffness that lead to a given bending and torsio...

Abstract
The high incidence rate of concussions in football provides a unique opportunity to collect biomechanical data to characterize mild traumatic brain injury. The goal of this study was to validate a six degree of freedom (6DOF) measurement device with 12 single-axis accelerometers that uses a novel alg...

Abstract
Comparing the PET data obtained with the BrainPET to those of the HR+ scanner demonstrated the high image quality and the superior resolution capability of the BrainPET. Furthermore, it is shown that various MR images of excellent quality could be acquired simultaneously with BrainPET scans without...

Abstract
We analyzed the success rate of Glidescope intubation in various intubation scenarios. In addition, the incidence and character of complications associated with Glidescope use were recorded. Predictors of Glidescope intubation failure were determined using a logistic regression analysis.
Overall suc...

Abstract
We report on the layer-by-layer growth of the organic semiconductor molecule p-sexiphenyl (6P) on the transparent electrode material graphene. Low energy electron microscopy and micro low energy electron diffraction reveal the morphological and structural evolution of the thin film. The layer-by-lay...

Abstract
CdSe quantum dot (QD ) sensitized TiO(2) films have been fabricated using a one-step microwave assisted chemical bath deposition (MACBD) technique and used as photoanodes for quantum dot sensitized solar cells. This technique allows direct and rapid deposition and a good contact betw...

Abstract
Conducting polymer with 1D nanostructure exhibits excellent electrochemical performances but a poor cyclability that limits its use in supercapacitors. In this work, a novel composite electrode made of polyaniline nanowire-titania nanotube array was synthesized via a simple and inexp...

Abstract
We describe a facile and feasible synthesis method for patterning nanogold particles onto magnetic mesoporous CoFe(2)O(4) nanostructures (Au-MMNs) by using poly(vinyl pyrrolidone) (PVP) as cross-linker. Initially, mesoporous CoFe(2)O(4) nanoparticles were initially synthesized with a thermal decompo...

Abstract
We report a facile and general method for the preparation of alkylamine capped metal (Au and Ag) nanoparticle "ink" with high solubility. Using these metal nanoparticle "inks", we have demonstrated their applications for large scale fabrication of highly efficient surface enhanced Raman scattering (...

Abstract
We demonstrate organic phototransistors with polymer/polymer bulk heterojunction blend films (mixtures of p-type and n-type semiconducting polymers), which can be fabricated by inexpensive solution processes at room temperature. The key idea here is to effectively exploit hole charges (from p-type p...

Abstract
Logic switch based on individual ZnO nanotetrapods was designed and the electromechanical properties were in situ investigated using scanning electron microscopy. The current through two adjacent legs of the tetrapod can be tuned by applying force on the leg that is perpendicular to...

Abstract
The aim of the study was to evaluate in vivo and compare, in terms of the quality and number of ultra high-molecular polyethylene (UHMWPE) wear particles, total knee replacements of identical construction differing only in the material used for femoral component production, i.e., CoCrMo alloy or ZrO2...

Abstract
We detected the appearance of highly sensitive and selective NH(3) gas-sensing properties after 45-75 days of sensor operation. Detailed observation of the morphology and composition of the as-fabricated nano-structured Au-SE after 75 days operation at 700 °C revealed the gradual accumulation of he...

Abstract
The video laryngoscope is a useful tool in intubation training as it allows both the trainer and the student to share the same view of the airway during the intubation process. In this study, the Center for Advanced Technology and Telemedicine's airway training program employed videolaryngoscopy (VL)...

Abstract
A SensAble Omni force feedback device has been modified to increase the face validity of a needle insertion simulation. The new end effector uses a real needle hub and shortened needle shaft in place of the Omni's pre-fitted pen shaped end effector. This modification facilitates correct procedural tr...

Abstract
We present NeuroSim, the prototype of a training simulator for open surgical interventions on the human brain. The simulator is based on virtual reality and uses real-time simulation algorithms to interact with models generated from MRT- or CT-datasets. NeuroSim provides a native interface by using a...

Abstract
The endotracheal bougie is used for difficult intubations when only a minimal glottic view is obtained. Standard bougies are designed for use during direct, line-of-sight viewing of the glottic opening. With videolaryngoscopy, intubators "see around the corner", thus requiring a bougie which can be s...

Abstract
This study examined the utility of a novel tongue retractor created with a wider working blade and a more ergonomic curve to provide jaw lift and tongue management with one hand during intubation. Anesthesia providers participated in simulated intubation of a difficult manikin using the novel tongue...

Abstract
Previous studies have shown that the videolaryngoscope is an excellent intubation training tool as it allows the student and trainer to share the same anatomical view of the airway. Use of this training tool is limited; however, as many times intubation training must take place outside the hospital e...
