INTRODUCTION Since the recent descriptions of the anterolateral ligament (ALL), the role played by the anterolateral peripheral structures in the rotational control of the knee is again being debated. The objective of this study was to identify the structures during internal tibial rotation and then to define their anatomical characteristics. We hypothesized that internal rotation would tighten...

background: percutaneous endoscopic gastrostomy (peg) is the standard method for enteral feeding in patients predicted to require long-term enteral nutrition because of dysphagia. the aim of this study was to assess the complications of percutaneous endoscopic gastrostomy performed using the pull technique. methods: between january 2011 and december 2011, 74 patients underwent percutaneous endo...

We examined the time course of threshold reduction in the Gabor lateral masking paradigm. Contrast detection thresholds were measured (2AFC) for a briefly presented (36 ms) foveal Gabor signal (GS), preceded by a presentation (90 ms) of two high-contrast GS flanked masks, with stimulus onset asynchrony (SOA) varying from 0 to 16,290 ms. Using target-to-mask separations of 3 lambda and 12 lambda...

In the path reporting problem, we preprocess a tree on n nodes each of which is assigned a weight, such that given an arbitrary path and a weight range, we can report the nodes whose weights are within the range. We consider this problem in dynamic settings, and propose the first non-trivial linear-space solution that supports path reporting in O((lgn/ lg lgn)+occ lgn/ lg lgn) time, where occ i...

Motivated by the structure of networks of cross-linked cytoskeletal biopolymers, we study orientationally ordered phases in two-dimensional networks of randomly cross-linked semiflexible polymers. We consider permanent cross-links which prescribe a finite angle and treat them as quenched disorder in a semimicroscopic replica field theory. Starting from a fluid of un-cross-linked polymers and sm...

It is demonstrated that direct ultraviolet writing of waveguides is a method suitable for mass production of compact variable optical attenuators with low insertion loss, low polarization-dependent loss, and high dynamic range. The fabrication setup is shown to be robust, providing good device performance over a period of many months without maintenance.
