Evaluation of the characteristics of workers injured on the job requiring hospitalization, and employer compliance with OSHA's reporting requirement for these work‐related hospitalizations

American Journal of Industrial Medicine, Volume 66, Issue 2, Page 109-121, February 2023., 2023
Abstract Background The Occupational Safety and Health Administration (OSHA) implemented a new standard in 2014 requiring employers to report nearly all work‐related inpatient hospitalizations within 24 h of the event. We examined the characteristics of the injured workers who were reported and the compliance of Michigan employers with the regulation ...

A Model of Epigenetic Inheritance Accounts for Unexpected Adaptation to Unforeseen Challenges

Advanced Science, EarlyView.
A general model of inheriting changes that are acquired during the lifetime of individuals demonstrates tremendous benefits to the population, including escape from extinction in changing environments. Contrasting the model with experimental data shows that inheritance of acquired changes enables rapid adaptation to unforeseen challenges, and accounts ...

Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials

Advanced Science, EarlyView.
This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

When good intentions are not enough: Professionals’ perceptions of the South Australian communication partner scheme

Australian Journal of Social Issues, Volume 57, Issue 4, Page 970-986, December 2022., 2022
Abstract Children and other vulnerable parties such as those with a cognitive, social or communication impairment frequently struggle to understand, and be understood in, the criminal justice environment. One way this has been addressed in jurisdictions around Australia and overseas is through the introduction of intermediary (or communication partner)

Biological Reinforced Concrete for Cartilage Repair With 3D Printing

Advanced Science, EarlyView.
Inspired by concrete rebar structures in engineering, the concept of biological reinforced concrete uses 3D‐printed ultrafine fiber networks (UFNs) as biodegradable “biorebars”， hybrid biohydrogels as “biocement”， and stem cells as “bioactive aggregates” to fabricate biomimetic cartilage.

Segmentation of cracks in 3d images of fiber reinforced concrete using deep learning [PDF]

arXiv
Cracks in concrete structures are very common and are an integral part of this heterogeneous material. Characteristics of cracks induced by standardized tests yield valuable information about the tested concrete formulation and its mechanical properties. Observing cracks on the surface of the concrete structure leaves a wealth of structural information
