Metalearning‐Driven Inverse Optimization for Precision Microstructure Fabrication in Digital Light Processing Three‐Dimensional Printing

Advanced Intelligent Systems, EarlyView.
Metalearning‐based inverse optimization enables precise microscale three‐dimensional printing using a DLP system. Distorted structures from conventional printing are analyzed via neural network regression, which predicts optimal exposure time and mask design.

Schnelle RASER‐MRT

Angewandte Chemie, EarlyView.
Schnelle RASER‐MRT ermöglicht Bildgebung ohne RF‐Anregung. Stattdessen wird eine Populationsinversion der Kernspins durch SABRE‐Hyperpolarisation erzeugt, die eine Selbstanregung durch RASER ermöglicht. Wenn die gewünschte transversale Magnetisierung aufgebaut ist, wird herkömmliche EPI‐Kodierung ausgelöst, um das Bild aufzuzeichnen.

Evaluation of a fast kV switching dual energy CT in deriving relative stopping power using tissue equivalent phantoms of various sizes. [PDF]

Med Phys
Abstract Background Dual energy CT (DECT) has been demonstrated to improve relative stopping power (RSP) estimation with knowledge of the effective atomic number (Zeff${Z_{{\mathrm{eff}}}}$) and relative electron density (RED). A fast kV switching DECT has been developed and it is necessary to quantify the accuracy of RSP prior to clinical use ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
