We study the bunching identification strategy for an elasticity parameter that summarizes agents' response to changes in slope (kink) or intercept (notch) of a schedule incentives. A notch identifies but kink does not, when distribution agents is fully flexible. We propose new non-parametric and semi-parametric assumptions on are weaker than currently made literature. revisit original em...

INTRODUCTION: Polyethylene wear is a recurrent problem in joint arthroplasty. In addition to permanent deformation or complete destruction of the component, small debris particles are also associated to inflammation reaction of the surrounding bone, eventually leading to the failure of the bound between the implant and the host bone, and implant loosening. In anatomic total shoulder arthroplast...

The management of irreparable rotator cuff tears associated with osteoarthritis of the glenohumeral joint has long been challenging. Reverse total shoulder arthroplasty (RSA) was designed to provide pain relief and improve shoulder function in patients with severe rotator cuff tear arthropathy. While this procedure has been known to reduce pain, improve strength and increase range of motion in ...

BACKGROUND Proximal humerus fractures are one of the most common fractures among elderly patients. We performed a systematic review to detail the demographics, outcomes, and complications of patients who undergo reverse shoulder arthroplasty for complex proximal humerus fractures. METHODS A systematic review of the literature was performed. Two reviewers assessed and confirmed the methodical ...

INTRODUCTION Shoulder injuries are common in baseball players, which may be related to scapular malposition (Burkhart 2003). Although a few studies demonstrated scapular malposition in baseball players using clinical measurement (Laudner 2010, Thomas 2010), no data currently exist that demonstrated 3-dimentional (3D) scapular position and orientation using a technique that eliminates skin artif...

 In through-wafer silicon etching using highdensity low-pressure inductively coupled plasma, a notching (or footing) effect occurs at the silicon-insulator interface. The insulator layer is common, as the silicon wafer has either an oxide layer to avoid break through of the plasma or is bonded to a handle wafer using either photoresist or other adhesives. Notching at the foot of micro-structur...

The first aim of this investigation was to quantify the distribution of trapezius muscle activity with different scapular postures while seated. The second aim of this investigation was to examine the association between changes in cervical and scapular posture when attempting to recruit different subdivisions of the trapezius muscle. Cervical posture, scapular posture, and trapezius muscle act...
