Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

steel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

The Impact of Digital Technologies on Skills‐to‐Job Mismatches

New Technology, Work and Employment, EarlyView.
ABSTRACT A pervasive discourse calls for worker upskilling amid ongoing digital transformation. This study introduces a skills‐to‐job mismatch perspective into research on the digital transformation of work by conceptualising technological adoption as a process that reshapes the relationship between workers’ skill endowments and evolving job ...

A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this
