Article Synopsis
  • Today's precise timekeeping relies on optical atomic clocks, but nuclear clocks, using nuclear transitions, could offer enhanced accuracy for various scientific applications.
  • The elusive "Thorium Isomer" (Th) is a potential candidate for a nuclear clock, which has been under investigation for decades but only recently confirmed through direct detection in 2016.
  • Significant advances in characterizing Th's properties have been made, including determining its half-life and excitation energy, culminating in the first observation of its radiative decay, paving the way for further developments in precise timekeeping.

To deploy machine learning models on-device, practitioners use compression algorithms to shrink and speed up models while maintaining their high-quality output. A critical aspect of compression in practice is model comparison, including tracking many compression experiments, identifying subtle changes in model behavior, and negotiating complex accuracy-efficiency trade-offs. However, existing compression tools poorly support comparison, leading to tedious and, sometimes, incomplete analyses spread across disjoint tools.

Children with disability face many barriers to participating in community sports. Little Athletics Australia aims to increase fair and meaningful inclusion via a new structure which will enable all children to take part in the same contest by competing for their 'personal best' score. Named the True Inclusion Method (TIM), this new structure will be piloted in 13 sites across six states.

Nuclear forward scattering (NFS) is a synchrotron-based technique relying on the recoil-free nuclear resonance effect similar to Mössbauer spectroscopy. In this work, we introduce NFS for and measurements during electrocatalytic reactions. The technique enables faster data acquisition and better discrimination of certain iron sites in comparison to Mössbauer spectroscopy.

Making data visualizations accessible for people with disabilities remains a significant challenge in current practitioner efforts. Existing visualizations often lack an underlying navigable structure, fail to engage necessary input modalities, and rely heavily on visual-only rendering practices. These limitations exclude people with disabilities, especially users of assistive technologies.
