This paper reviews the NTIRE 2023 challenge on image super-resolution (×4), focusing proposed solutions and results. The task of (SR) is to generate a high-resolution (HR) output from corresponding low-resolution (LR) input by leveraging prior information paired LR-HR images. aim obtain network design/solution capable produce high-quality results with best performance (e.g., PSNR). We want explore how high we can achieve regardless computational cost model size FLOPs) data. track was measure...
To evaluate the mechanical properties of commonly available soft contact lens materials and compare results using custom-built MicroTensometer.The Young modulus, parameters for stress relaxation, toughness 18 types single vision lenses were measured MicroTensometer. Five each type soaked in standard phosphate buffered saline at a temperature 35°C. Each was flattened sliced into rectangular strip sample two parallel blades.The Acuvue Moist 1-Day SofLens Daily lowest moduli, whereas Air Optix...
To evaluate the optical power profiles of commercially available soft multifocal contact lenses and compare their designs.The 38 types lenses-three each-were measured in powers +6D, +3D, +1D, -1D, -3D, -6D using NIMO TR1504 (Lambda-X, Belgium). All were phosphate buffered saline across 8 mm optic zone diameter. Refractive index each lens material was CLR 12-70 (Index Instruments, UK), which used for converting medium to in-air radial profiles.Three basic identified: center-near,...
The number of missing child reports exceed police investigative capacity, yet some incidents are linked with harm, making effective risk assessment essential for safeguarding. Police data likely underrepresents harm to children due being undisclosed, and going unreported. A better understanding associated could help develop appropriate interventions reduce prevent harm. This study examined 18 months published Child Safeguarding Practice Reviews across England – a previously overlooked...
To evaluate the repeatability of power profiles measured on NIMO TR1504 (Lambda-X, Belgium) and investigate effects lens decentration for single vision (SV), bifocal (BF) multifocal (MF) contact lenses.
Abstract This article presents a discussion of the emerging ethical issue geodata privacy in geographical research. The paper highlights importance considering challenges to when working with geographically explicit data and explores ways which researchers practitioners can be conscious these issues. Through summarising key problems this area presenting outstanding open research areas questions from seminar series on privacy, we highlight important considerations for future field. We focus...
Presbyopia is an age related, gradual loss of accommodation, mainly due to changes in the crystalline lens. As part research efforts understand and cure this condition, ex vivo, cross-sectional optical coherence tomography images lenses were obtained by using Ex-Vivo Accommodation Simulator (EVAS II) instrument analyzed extract their physical properties. Various filters edge detection methods applied isolate contour. An ellipse fitted lens outline obtain central reference point for...
The aim was to study the reliability of measurements RTVue (Optovue, Fremont, CA, USA) anterior segment optical coherence tomographer (AS-OCT) and assess how results can be improved by analysing raw tomography data with customised image analysis software applying correction factors.Five AS-OCT instruments (ver. 4.0) were assessed imaging gauge blocks three different lengths, single/stepped glass plate (microscope slides) flat window check for width, depth linearity measurement scans. Five...
Contemporary criminology issues are increasingly global, cross-cultural, and multilingual. Moreover, students from different cultural national backgrounds will need to apply data analytics in their respective contexts. Crime used statistical courses should reflect this diversity, turn enhance the equality inclusivity of teaching curriculum. Supported by evidence-based pedagogic principles evaluations, researchers have identified strategies learning quantitative skills. Promoting students'...
Presbyopia is the age related, gradual loss of accommodation, mainly due to changes in crystalline lens. As part research efforts understand and cure this condition, ex vivo, cross-sectional OCT images lenses were obtained analyzed extract their physical optical properties. The raw are distorted, as probing beam passing through media different refractive indices refraction on curved surfaces. In a first step, various filters, edge detection pattern matching methods applied isolate contour....
To study the effect of inlay implantation on corneal shape, assessing changes using optical coherence tomography (OCT) and a customized image analysis software.Thirteen rabbit eyes were operated on, with positive-powered inlays implanted into 11 2 serving as flap-only controls. Cross-sectional OCT images obtained Optovue preoperatively, 1 hour, week, month postoperatively. Topography maps preoperatively Medmont E300. Image software was built to extract thickness radius curvature. Anterior...
The impacts of a major hurricane on residential real estate can be devastating. Hurricane Sandy in New York City (NYC) is among the examples how flooding unexpectedly extend beyond FEMA flood zones. Such surprises or negative shocks provide property owners—especially those not flooded—with new information about future risks, based difference distance from zone and to actual locations flooding. We use difference-in-differences approach quantify effects these values for non-flooded NYC...

Cataract surgery usually involves the replacement of natural crystalline lens with a rigid or foldable intraocular to restore clear vision for patient. While great efforts have been placed on optimising shape and optical characteristics IOLs, little is know about mechanical properties these devices how they interact capsular bag once implanted. Mechanical measurements were performed 8 most commonly implanted IOLs using custom build micro tensometer. Measurement data will be presented...
