“How are you feeling?” Assessing reporting bias in a subjective measure of health by quantile regression [PDF]

open access: yes
In this paper we investigate reporting heterogeneity in the Visual Analogue Scale (VAS) when it is used to measure current health status in cardiovascular patients. We provide a new framework to identify reporting heterogeneity using quantile regressions.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Requirements and Evaluation of Commercial Digital Light Processing 3D Printers for Upscaled Production of Microstructured Tissue Culture Devices

open access: yesAdvanced Engineering Materials, EarlyView.
Commercial light‐based 3D printers increasingly find use for industry‐scale production of microstructured tissue culture devices. How can commercial printer performance be assessed for a given application? This work introduces simplified quantitative metrics based on microstructural fidelity analysis, addressing key manufacturing challenges in scaling ...

On the Investigation of a Sustainable Two Step Laser‐Based Surface Treatment for the Functionalization of Additive Manufactured Ti–6Al–4V Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Impact of Structural Adhesive Hybridization Strategy on the Performance of In‐Mold Electronics Devices Across Thermoforming and Injection Molding

open access: yesAdvanced Engineering Materials, EarlyView.
In‐mold electronics (IME) undergo complex thermoforming and over‐molding processes that strain device integrity. This study demonstrates how adapting the amount and placement of structural adhesive to local deformation levels preserves electrical functionality.
