Detecting shielded special nuclear material, such as nuclear explosives, is a difficult challenge pursued by non-proliferation, anti-terrorism, and nuclear security programs worldwide. Interrogation with intense fast-neutron pulses is a promising method to characterize concealed nuclear material rapidly but is limited by suitable source availability and proven instrumentation. In this study we have pioneered a demonstration of such an interrogation method using a high-intensity, short-pulse, laser-driven neutron source that offers potential benefits compared to conventional neutron sources.

- Emergency doctors experience high levels of uncertainty due to limited patient information and time constraints, prompting a study on how 'uncertainty tolerance' (UT) affects their work.
- A questionnaire was distributed among emergency doctors to develop a UT measure and analyze its impact on doctors' experience, patient outcomes, and resource utilization during encounters with specific medical issues.
- Findings showed that higher UT is associated with better psychological well-being among doctors, such as increased resilience and lower burnout, but it did not significantly influence patient outcomes or resource usage.
Background: Guidelines for sepsis recommend treating those at highest risk within 1 hour. The emergency care system can only achieve this if sepsis is recognised and prioritised. Ambulance services can use prehospital early warning scores alongside paramedic diagnostic impression to prioritise patients for treatment or early assessment in the emergency department.
