AIMS To compare the postoperative performance of single and three piece acrylic foldable intraocular lenses (IOLs). METHODS 20 patients underwent bilateral cataract surgery with a single piece SA30AL IOL in one eye and a three piece MA30BA IOL in the other eye. The eyes were randomly assigned to either a single or three piece lens. The amount of IOL decentration and tilt, area of anterior cap...

Article history: Received 21 May 2017 Received in revised form 19 July 2017 Accepted 26 July 2017 Available online 7 August 2017 For the next generation display, foldable display is one of the attractive candidates. However, the degradation effects due to themechanical stress on the device are unavoidable. A strain due to themechanical stress generates cracks on the thin film transistors (TFTs)...

purpose : cataract surgery is the most common ocular surgery worldwide and in modern era of phacoemulsification with posterior chamber intraocular lens (pc iol) implantation, refractive aspects of surgery is as important as the surgery itself. after the iol implantation, the anterior chamber depth (acd) is increased and the iridiocorneal angle is widened. these changes should be considered for ...

Evidence is presented suggesting, for the first time, that the protein foldability metric sigma = (T(theta)-T(f))/T(theta), where T(theta) and T(f) are, respectively, the collapse and folding transition temperatures, could be used also to measure the foldability of RNA sequences. These results provide further evidence of similarities between the folding energy landscapes of proteins and RNA. Th...

The presence of highly regular secondary structure motifs in protein structure is a fascinating area of study. The secondary structures play important roles in protein structure and protein folding. We investigate the folding properties of protein by introducing the effect of secondary structure elements. We observed the emergence of several structures with both large average energy gap and hig...

Origami, the art of paper sculpture, is a fresh challenge for the field of robotic manipulation, and provides a concrete example for many difficult and general manipulation problems. This paper describes our initial exploration, and highlights key problems in manipulation, modeling, and design of foldable structures. Results include the first origami-folding robot, a complete fold-sequence plan...
