Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma
FEBS Open Bio, EarlyView.GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Welding in the WorldAbstract In V groove butt welding with a ceramic backing material, the molten pool should penetrate well. Regardless of the gap fluctuations, the molten pool must maintain a good penetration shape. For this purpose, the molten pool state is detected using ResNet50 as one of the deep learning.

Thin Molten Pool Behaviors in Blue Laser Microjoining
Welding Journal, 2022 Thin copper materials are difficult to weld using infrared lasers (IR) due to their low energy absorption. A blue laser with a wavelength of 450 nm strongly increases energy absorption and successfully realized the microjoining of a copper material with a thickness of 0.1 mm.
