Liver Stiffness Characterization of OGTLKO Mouse Model of Progressive Liver Fibrosis

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives O‐GlcNAcylation plays a key regulatory role in hepatic physiology, and its disruption leads to fibrosis in liver‐specific OGT knockout mice (OGTLKO), making this model valuable for studying advanced metabolic dysfunction‐associated steatohepatitis (MASH).

All‐inside meniscal repair using polyether ether ketone versus all‐suture anchors: No difference in failure rates at three‐follow‐up in a retrospective cohort of 2253 patients

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare mid‐term failure rates of next‐generation all‐inside meniscal repair using polyether ether ketone (PEEK) anchors versus all‐suture anchors in a large patient cohort. The null hypothesis was that there would be no difference in failure rates between PEEK and all‐suture anchors.

Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Dosimetric Performance of A-Si Electronic Portal Imaging Devices

open access: yesInternational Journal of Medical Physics, Clinical Engineering and Radiation Oncology, 2016
The majority of EPID dosimetry literature discusses response linearity and the so-called image lag and ghosting effects despite the lack of a common definition of these quantities. However, the results of these studies are generally not consistent, and it is often difficult to compare the results from different studies. We present here a detailed study

Linking to images and AI‐based identification tools—The only way for Flora projects to survive

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Floras are comprehensive and authoritative catalogues of plants growing in an area of interest. They help people find and name plants, which is achieved by a combination of images, drawings, and text, rarely also maps. Like other catalogues (lexica, dictionaries, telephone books), Floras will not survive unless they move online and become portable ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.
