Fluorescence imaging of individual ions and molecules in pressurized noble gases for barium tagging in Xe.

The imaging of individual Ba ions in high pressure xenon gas is one possible way to attain background-free sensitivity to neutrinoless double beta decay and hence establish the Majorana nature of the neutrino. In this paper we demonstrate selective single Ba ion imaging inside a high-pressure xenon gas environment. Ba ions chelated with molecular chemosensors are resolved at the gas-solid interface using a diffraction-limited imaging system with scan area of 1 × 1 cm located inside 10 bar of xenon gas.

Propofol-induced transient arginine vasopressin deficiency.

Summary: We describe and characterise the case of a 26-year-old female undergoing surgery for a right-sided sinonasal alveolar rhabdomyosarcoma who developed profound, transient arginine vasopressin deficiency (AVP-D, formerly central diabetes insipidus (DI)) associated with anaesthesia. In this case report, we characterise the development of AVP-D with serial copeptin and paired urine and serum osmolality measurements. Based on the anaesthetic agent's profile and the literature, we attribute this presentation to propofol exposure.

Hello, is it me you're Stopping for? The Effect of external Human Machine Interface Familiarity on Pedestrians' Crossing Behaviour in an Ambiguous Situation.

Objective: We investigated how different deceleration intentions (i.e. an automated vehicle either decelerated for leading traffic or yielded for pedestrians) and a novel (Slow Pulsing Light Band - SPLB) or familiar (Flashing Headlights - FH) external Human Machine Interface (eHMI) informed pedestrians' crossing behaviour.

Demonstration of event position reconstruction based on diffusion in the NEXT-white detector.

Noble element time projection chambers are a leading technology for rare event detection in physics, such as for dark matter and neutrinoless double beta decay searches. Time projection chambers typically assign event position in the drift direction using the relative timing of prompt scintillation and delayed charge collection signals, allowing for reconstruction of an absolute position in the drift direction. In this paper, alternate methods for assigning event drift distance via quantification of electron diffusion in a pure high pressure xenon gas time projection chamber are explored.
