PURPOSE To better understand functional loss in the macular area of preperimetric glaucoma patients exhibiting structural loss by exploring correlations between parameters of the ganglion cell-inner plexiform layer (GCIPL) and 10-2 short-wavelength perimetry (SWAP). METHODS One hundred thirty-four patients underwent 10-2 SWAP and conventional 24-2 visual field (VF) testing using a Humphrey fi...

BACKGROUND Swaps are often used to encourage healthier food choices, but there is little evidence of their effectiveness. The current study assessed the impact of offering swaps on groceries purchased within a bespoke online supermarket; specifically the objective was to measure the impact on energy density (ED) of food purchases following the offer of lower ED alternatives (a) at point of sele...

It is often questioned whether a change in fixation (to the amblyopic eye) is necessary for atropine treatment to be successful. Recent retrospective reviews report that patients swapping fixation during atropine treatment have significantly greater improvement in visual acuity compared with those who do not swap. Studies by the Pediatric Eye Disease Investigator Group and others have found tha...

The ever-increasing amounts of simulation data produced by scientists demand high-end parallel visualization capability. However, image compositing, which requires interprocessor communication, is often the bottleneck stage for parallel rendering of large volume data sets. Existing image compositing solutions either incur a large number of messages exchanged among processors (such as the direct...

The exchange of a computer system’s components during operation can be accomplished by the so called Hot Swap technology. This technology makes it possible to continuously run a computer system without the necessity of a shutdown for maintenance purposes, e.g. upgrading of a network adapter. Thus the overall uptime of a system can be drastically increased. The Hot Swap capability has been integ...

bstract. A new steganographic method for data hiding in jig swap uzzle images is proposed. First, a color image is taken as input and ivided into blocks. Second, each block is rearranged to a new poition according to the secret data and a stegokey. The resulting mage is a perfect jig swap puzzle. The original image is needed for xtracting the secret data. Under the assumption that the receiver ...
