Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Inferring Inter‐Well Fracture Interactions in Unconventional Reservoirs Using Fiber‐Optic Sensing and Coupled Multiphysics Modelling

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Integrating distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) data with numerical simulations to analyze inter‐well interference and production responses remains challenging. This study employs a coupled thermal–hydraulic–mechanical simulation framework to model heat transfer, fluid flow, and geomechanical responses ...

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

open access: yesPolymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

open access: yesPest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

On‐farm comparison of aerial and chemigation application methods for Striacosta albicosta (lepidoptera: Noctuidae) management in corn using pyrethroid and diamide insecticides

open access: yesPest Management Science, EarlyView.
Aerial applications deposited more insecticide on tassels than on ear level (36.4% vs. 19.8%). Across both application methods, chlorantraniliprole minimized ear injury, while bifenthrin provided moderate control. Effective management of S. albicosta requires delivering sufficient insecticide concentration to the target site and achieving adequate ...

Notoginsenoside R2 Antagonizes Renal Interstitial Fibrosis by Regulating Fatty Acid Oxidation via the CASP2/ALDH3A1 Axis

open access: yesPhytotherapy Research, EarlyView.
Proposed mechanism by which notoginsenoside R2 (NGR2) attenuates renal interstitial fibrosis. In injured renal tubular epithelial cells, CASP2 downregulation and enhanced ubiquitin‐dependent degradation of ALDH3A1 disrupt mitochondria‐associated endoplasmic reticulum membranes (MAMs) and impair fatty acid oxidation (FAO), leading to lipid accumulation ...

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).
