A Preliminary Exploratory Measurement Model for Systems Thinking in Defence and Aerospace Engineering: A Bifurcated Framework Developed via Multiple Correspondence Analysis

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Modern engineering faces a ‘complexity crisis’ characterized by interlinked, multidisciplinary ‘wicked problems’, particularly within the defence and aerospace sectors. Although systems thinking is recognized as a critical competency for navigating this environment, empirical quantitative frameworks for its measurement remain limited.

Exploration of High and Low Frequency Options for Subperception Spinal Cord Stimulation Using Neural Dosing Parameter Relationships: The HALO Study

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Subperception spinal cord stimulation (SCS) is described mostly utilizing waveforms that require high energy. However, the necessity of these waveforms for effective subperception has not been established. We aimed to explore whether effective subperception pain relief can be achieved using frequencies below 1 kHz.

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Wild pigs (Sus scrofa) prefer inoculated peanuts over whole‐kernel corn in cafeteria‐style study

Wildlife Society Bulletin, EarlyView.
In this study, we explored bait preference of wild pigs (Sus scrofa), a highly invasive species where primary removal efforts include the use of bait and corral‐style trapping. In addition, we investigated preferences of a common nontarget to identify a bait that is preferred by wild pigs and not by white‐tailed deer (Odocoileus virginianus).

Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.
