Porosity control of in situ forming tungsten carbide in laser additive manufacturing (LAM)
(2020)
The effect of powder compression on the formation of porosity when heating with a laser beam has been investigated. The starting materials were elemental powders of Fe, W and C which were locally melted to form WC in Fe ...
An Efficient Synthesis and Photoelectric Properties of Green Carbon Quantum Dots with High Fluorescent Quantum Yield
(2020-01-01)
To greatly improve the production quality and efficiency of carbon quantum dots (CQDs), and provide a new approach for the large-scale production of high-quality CQDs, green carbon quantum dots (g-CQDs) with high product ...
The Elephant in the Room: Too Much Medicine in Musculoskeletal Practice
(2020-01-01)
While advances in assessment and management of musculoskeletal conditions have improved care for many people, there have been other, less beneficial developments in the provision of care for people with musculoskeletal ...
Critical Success Factors for Ensuring Bankable Completion Risk in PFI/PPP Megaprojects
(2020-01)
This study investigates project financiers' perspectives on the bankability of completion risk in private finance initiative and public–private partnership (PFI/PPP) megaprojects. Using a mixed methodology approach, focus ...
A General Traffic Flow Prediction Approach Based on Spatial-Temporal Graph Attention
(2020)
Accurate and reliable traffic flow prediction is critical to the safe and stable deployment of intelligent transportation systems. However, it is very challenging due to the complex spatial and temporal dependence of traffic ...
Modulation of speech-in-noise comprehension through transcranial current stimulation with the phase-shifted speech envelope
(2020-01)
Neural activity tracks the envelope of a speech signal at latencies from 50 ms to 300 ms. Modulating this neural tracking through transcranial alternating current stimulation influences speech comprehension. Two important ...
