Combined Use of Acoustic Measurement Techniques with X-ray Imaging for Real-Time Observation of Laser-Based Manufacturing

Metrology
Ensuring high-quality control in laser additive manufacturing and laser welding relies on the implementation of reliable and cost-effective real-time observation techniques. Real-time monitoring techniques play an important role in understanding critical

‘The Good Couscous That Pleases Us!’: The Meanings of Enduring Imperialist Imagery in Postcolonial French Food Advertising, 1970–2000

Gender &History, EarlyView.
ABSTRACT This article examines a wave of Orientalism‐inspired food commercials that appeared on television in France between 1975 and 2000. Older commercials for couscous were more banal, emphasizing a given product's superiority or affordability. Around 1975, however, there was a concerted shift in the advertising; new spots contained exoticized ...

Mechanism of keyhole evolution and welding quality of electron beam welded magnesium alloy with scanning path variation via modeling and numerical study

Journal of Magnesium and Alloys
Welding quality of electron beam welded joint is usually susceptible to the stability of keyhole during welding process. The more stable the keyhole, the better the welding quality.

Numerical simulation of periodic fluctuation in electron beam welding pool

Cailiao gongcheng, 2019
In order to further explore the mechanism during electron beam welding, electron beam welding was carried out on a 10mm 2219 aluminum alloy. A three-dimensional electron beam welding model in which volume of fluid (VOF) was combined with dynamic heat ...

Keyhole Foraminotomy Combined With Unilateral Laminotomy for Bilateral Decompression Under Biportal Endoscopic Spinal Surgery for the Treatment of Mixed‐Type Cervical Spondylosis

Orthopaedic Surgery, EarlyView.
Under biportal endoscopic spine surgery, one‐stage decompression combining keyhole foraminotomy and unilateral laminotomy for bilateral decompression (ULBD) for mixed‐type cervical spondylopathy can achieve favorable clinical outcomes with minimal compromise of spinal stability.

Enhancement of OCT signal interpretability in deep penetration laser welding of aluminum

Journal of Advanced Joining Processes
In laser deep penetration welding a constant weld depth is an essential quality measure that is usually obtained by in-line process monitoring techniques such as optical coherence tomography (OCT).

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Reducing Noise Induced by Cardiac Pulsatility in Brain Maps of R2* and Magnetic Susceptibility Using Tailored k‐space Sampling

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
With linear k‐space sampling trajectories, cardiac pulsation leads to MRI signal instabilities that increase the variability (standard deviation, SD) of R2* and QSM maps across repetitions. Here, we propose alternative trajectories that aim to mitigate the impact of cardiac‐induced noise in brain maps of R2* and QSM.
