Exposure of implanted episcleral element is a rare complication of buckling procedures. We describe a 40-year-old man who presented to our clinic complaining of foreign body sensation and irritation in his left eye which lasted several months. The patient history was positive for bilateral rhegmatogenous retinal detachment which was treated with sclera buckling. Upon presentation the left eye d...

PURPOSE We describe surgical outcomes in a single-surgeon, consecutive series of patients who received scleral buckle placement for primary retinal detachment using a modified external needle drainage technique. METHODS Eighty-two eyes of 80 patients with primary retinal detachment underwent scleral buckle placement with modified external needle drainage. Preoperative, postoperative, and surg...

Feasibility and efficiency of using carbon fibre reinforced polymer (CFRP) buckle arrestors in steel offshore pipelines with D/t 28 40 are investigated hyperbaric chamber tests. CFRP manufactured Prepreg (PP), Wet-Layup (WL) Vacuum Bagging (VB) curing methods, coarse fine sand surface preparations. A parametric study is performed that outlines the performance various geometric configurations. E...

A buckle fracture is a stable fracture where there is a dorsal cortex compression of the distal radius. A total of 117 children with buckle fracture treated at our institution were randomised prospectively into two treatment groups: soft cast or rigid cast. The rigid cast group attended clinic after three weeks for removal of the cast. In the soft cast group, the cast was removed by parents at ...

PROBLEM Safety-belt use reduces motor vehicle crash-related morbidity and mortality, yet an estimated 18% of drivers do not consistently buckle up (NHTSA, 2005). In 1985, Geller and colleagues developed an interpersonal Flash-for-Life prompt that increased belt use among 22% of 1,087 unbuckled drivers (Geller, Bruff, & Nimmer, 1985). METHOD The Flash-for-Life intervention was re-introduced at...

PURPOSE To evaluate the frequency, characteristics, causes, and risk factors of late recurrent retinal detachments (LRRD). METHODS The authors retrospectively analyzed 445 eyes operated consecutively for rhegmatogenous retinal detachment between 1990 and 2003 by the same surgeon. Only eyes with complete reattachment after a minimum follow-up of 6 months were included. The authors defined LRRD...

We propose and experimentally demonstrate a novel second-harmonic-generation (SHG) scheme capable of supporting temperature-insensitive phase-matching (PM) at various laser wavelengths. This versatile temperature-insensitive PM is designed by using two cascaded crystals with opposite signs of temperature derivation of phase-mismatch, in which the temperature-induced phase-mismatch in the first ...

August 29, 2013 Type Package Title Threshold Regression Version 1.0.2 Date 2012-11-26 Author Tao Xiao Maintainer Tao Xiao Depends survival, Formula Description Fit a threshold regression model based on the first-hitting-time of a boundary by the sample path of a Wiener diffusion process. The threshold regression methodology is well suited to applications involving survival ...

This paper examines the hypothesis that both stock returns and volatility are asymmetrical functions of past information derived from domestic and US stock market news. By employing a double-threshold regression GARCH model to investigate four major index return series, we find significant evidence to sustain the asymmetrical hypothesis of stock returns. Specifically, evidence strongly supports...
