Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

Structural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Multifunctional and Recyclable Bio‐Based Vitrimers With Tunable Properties for Sustainable Digital Light Processing 4D Printing

SusMat, EarlyView.
A bio‐based, photocurable vitrimer system is developed for sustainable digital light processing (DLP) 4D printing. The material exhibits tunable thermomechanical properties, shapes memory and reconfigurability, and supports repair, reprocessing, and reprinting through dynamic covalent bond exchange, offering a recyclable and multifunctional platform ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

Can prisons move people into better jobs? A look at correctional vocational training programs and sectoral employment outcomes

Criminology, EarlyView.
Abstract Three‐quarters of US prisons offer vocational training programs, which aim to place trainees in middle‐skills jobs in specific occupational sectors post‐release. These middle‐skills jobs may more effectively reduce recidivism than the jobs that normally characterize the labor market experience of the formerly incarcerated, yet whether ...

Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

Artificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical

When Jobs Change: Skills Mismatch and the Value of Training

British Journal of Industrial Relations, EarlyView.
ABSTRACT This article examines the impact of rapidly changing skill requirements on skills mismatch in Europe and the role of training in mitigating adverse effects. Using data on approximately 70 million online job vacancies, we estimate the extent to which occupational skill requirements changed between 2019 and 2023 across European Union (EU ...
