Ground Control Point Distribution for Accurate Kilometre-Scale Topographic Mapping Using an RTK-GNSS Unmanned Aerial Vehicle and SfM Photogrammetry

open access: yesDrones, 2020
Unmanned Aerial Vehicles (UAVs) have revolutionised the availability of high resolution topographic data in many disciplines due to their relatively low-cost and ease of deployment.

Serum Apelin‐13 and Galectin‐3 in COVID‐19: Associations With Routine Biochemical Parameters and Diagnostic Performance in a Case–Control Study

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
Serum Apelin‐13 and Galectin‐3 levels were measured by ELISA in COVID‐19–positive patients and controls and evaluated alongside routine biochemical parameters. COVID‐19 patients showed significant alterations in liver, renal, inflammatory, and metabolic markers.

Impacts of GCP Distributions on UAV-PPK Photogrammetry at Sermeq Avannarleq Glacier, Greenland

open access: yesRemote Sensing
Real-Time/Post-Processing Kinematic (RTK/PPK) technology has been widely applied in Unmanned Aerial Vehicle (UAV) photogrammetry in glaciological research. Considering that ground control points (GCPs) cannot be set on glaciers, evaluating the impacts of

Pediatric home‐based central venous access device dressings: Medical liquid adhesive versus standard care to reduce dressing disruption: The STICKY‐kids RCT protocol

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Central venous access devices (CVADs) are frequently used in Hospital‐At‐Home models to facilitate prolonged intravenous treatment for children. Premature CVAD dressing disruption is common and contributes to device failure. This protocol describes a trial evaluating the adjunctive use of medical liquid adhesive at the dressing–skin

Multifunctional Ground Control Points with a Wireless Network for Communication with a UAV

open access: yesSensors, 2019
Ground control points (GCPs) are commonly used for georeferencing in remote sensing. Precise position measurement of the GCPs typically requires careful ground surveying, which is time-consuming and labor-intensive and thus excessively costly if it needs

A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Star-Based Calibration of the Installation Between the Camera and Star Sensor of the Luojia 1-01 Satellite

open access: yesRemote Sensing, 2019
Ground control points (GCPs) are generally used to calibrate the installation between the camera and star sensor of a satellite in orbit and improve the geometric positioning accuracy of the satellite.

Exploring stressor exposure and mental health symptom patterns among forcibly displaced people: A latent profile analysis

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract The association between trauma exposure and mental health among forcibly displaced people (FDP) is well‐documented. However, prior research has largely employed variable‐centered approaches, which may obscure heterogeneity in individual experiences.
