Precise Point Positioning Using Triple GNSS Constellations in Various Modes

Sensors, 2016
This paper introduces a new dual-frequency precise point positioning (PPP) model, which combines the observations from three different global navigation satellite system (GNSS) constellations, namely GPS, Galileo, and BeiDou.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Preparation and Evaluation of Biodegradable Film From Zinc Oxide Nanoparticles‐Carboxymethyl Cellulose‐Gelatin Containing Salvia viridis Anthocyanin

Food Chemistry International, EarlyView.
Different percentages of ANT affected the physical and mechanical characteristics of the film. The results indicated that this produced film is a useful tool for monitoring the freshness of food products.. ABSTRACT In recent years, growing environmental concerns have promoted the use of natural and biodegradable polymers in food packaging applications.

Peer PPP-RTK: toward an affordable real-time high accuracy service

, 2022
The objective of this thesis is to develop, test and analyze the performance of a high accuracy GNSS PPP-RTK (Precise Point Positioning- Real Time Kinematic) operational framework based on a dense network of peer users, through the exchange of precise Ionospheric and Tropospheric estimates between peers. The PPP-AR (PPP Ambiguity Resolution) technique,
