How could body-augmenting technology enable human digital twins to facilitate spiritual experiences? - Springer Nature Link

Recently, there has been increased interest in monitoring the effects of climate change upon the world’s marine ecosystems, particularly coral reefs. These delicate ecosystems are especially threatened due to their sensitivity to ocean warming and acidification, leading to unprecedented levels of coral bleaching and die-off in recent years. However, current global aquatic remote sensing datasets are unable to quantify changes in marine ecosystems at spatial and temporal scales relevant to their growth. We at LAS are directly addressing this challenge through recent UAV imaging campaigns directed towards coral reefs, utilizing a new algorithm known as Fluid Lensing capable of removing optical distortions caused by the fluid surface to produce cm-scale resolution imagery of benthic cover. Taking these data products, we were able to generate highly detailed and accurate maps of coral cover and morphology breakdown utilizing MAP estimation, with error rates of 5% and 8% , respectively.

TL;DR: Get lifetime access to PDF Expert for Mac for $79.99 (reg. $139.99), with tools for editing text, rearranging pages, signing forms, and working with scanned PDFs. Your Mac can handle some pretty impressive things, so it’s a little annoying when editing a PDF becomes the task that slows you down. Fixing one typo shouldn’t require a new workflow, and signing a form shouldn’t turn into a whole afternoon of troubleshooting. PDF Expert brings tools for editing text, inserting images, signing forms, and converting documents into one app. For a limited time, new users can get a lifetime subscription for $79.99 (reg. $139.99). The app lets you edit existing PDF text, replace images, add links, and make changes without rebuilding a document from scratch. You can also highlight important sections, leave comments, and add notes when reviewing reports, contracts, or class materials. If your PDFs are scattered across multiple files, PDF Expert can merge them into one document or split a larger file into smaller ones. You can rearrange, rotate, and delete pages, too, which is useful when someone sends you a 40-page document and you only need three pages.
