We evaluated associations of energy-adjusted tertiles of protein intake (ie, total, animal, plant, animal/plant ratio) with incident hip fracture and whether total calcium intake modified these associations  ...  In the 800 mg/day or more group, T3 of animal protein had an 85% reduced hip fracture risk (HR ¼ 0.15, 95% CI 0.02-0.92, p ¼ .04) versus T1 (p trend ¼ .04).  ...  This study was supported by National Institutes of Health Grants R01 AR53205 and R01 AR/AG 41398 and NHLBI's Framingham Study Contract Grant Number N01-HC-25195.  ...

Frames from an animation of an unfortunate and hollow, yet energetic, bunny fracturing on the ground. Compelling animation of fracture is a vital challenge for computer graphics.  ...  As a result, our method is able to animate energetic fracture scenarios with results comparable to continuum mechanics approaches, but with the computational efficiency of rigid body simulation.  ...  INTRODUCTION The creation of large-scale scenes of destruction has emerged as one of the greatest successes of physics-based animation.  ...
