Professionalism lapses in health professions training: Navigating the ‘Yellow Card’ moments for transformative learning

open access: yesMedical Education, Volume 59, Issue 4, Page 418-427, April 2025.
Abstract Introduction Health professions training programmes face increasing reports of professionalism lapses, which can delay, or end, trainee progression. How programmes respond to professionalism lapses to facilitate professional identity development has not been clarified.

A Nutrient‐Responsive LuxR Regulator Orchestrates Effector Gene Expression Across the Legionella Genus

open access: yesMolecular Microbiology, EarlyView.
LexR1 is a LuxR‐type regulator that links nutrient sensing to effector gene expression in Legionella. Activated by a casamino acid‐derived ligand, LexR1 directly controls multiple effector genes using a conserved regulatory element present in numerous putative effectors across different Legionella species.

Predictive evolutionary genomics: principles, validation, and practice

open access: yesNew Phytologist, EarlyView.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Hot Spot Formation in Mock Materials in Impact Sensitivity Testing by Drop Hammer

Propellants, Explosives, Pyrotechnics, 2017
AbstractPowder and granulated sugars were exposed to the drop hammer impact test configured with 120‐ and 180‐grit Si/C sandpapers. The sugars were selected as mock materials for HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine). The drop heights ranged from 24.2 to 40.7 cm.

Multiple Reference Impact Testing for Bridge Assessment with Drop Hammer

Advanced Materials Research, 2012
A new drop hammer was designed and used for multiple reference impact testing of two bridges. The drop hammer utilizes a multiple-rebound control system for successfully applying a single impact with repeatable high-level force for bridge testing. Signal analysis results indicate that the drop hammer provides a higher signal-noise ratio and a better ...

On the prediction of impact noise, X: The design and testing of a quietened drop hammer

Journal of Sound and Vibration, 1986
Part V in this series showed that the technique of predicting overall noise levels ( L eq per event) from vibration levels in a drop hammer produces surprisingly accurate results, allowing a good estimate of the contribution of each component to the overall noise.

Improvement of Drop‐Hammer Impact Testing for Safety Assessment of High Explosives Using 10‐mg Samples

Propellants, Explosives, Pyrotechnics
ABSTRACT In this study, we established an improved method for drop‐hammer impact testing of small quantities of high explosives (10 mg). We performed about seven hundred impact tests under various experimental conditions (e.g., sandpaper vs bare anvil, different sample masses, drop‐weights, and striker diameters ...
