Impact of staff training on body temperature measurements during cancer treatment: a single-site quality improvement project

Background: Neutropenic sepsis is a serious complication of cancer therapy, and can often be detected by the presence of abnormal body temperature, typically fever. Aims: This research aimed to improve home temperature measurement in a cancer triage unit following a previous audi...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Parallelised detection of bacteria viability using an electrode array and the Exeter Multiscope

Abstract Antimicrobial resistance remains a global existential threat. Given that antimicrobial therapy commonly starts before pathogen identification, rapid and scalable methods capable of determining effective antimicrobial compounds are needed. In this paper, we demonstrate a...

Programmable Anisotropic Terahertz Permittivity via High‐Aspect‐Ratio 3D‐Printed Dielectric Mesh Networks

ABSTRACT We present a 3D‐printed anisotropic dielectric with programmable terahertz permittivity. The design embeds a mesh network of high‐aspect‐ratio void channels within a bulk substrate. The anisotropic electromagnetic response, which depends on the orientation of the void ch...

Phase-matching-free sensing with undetected light using a nonlinear thin-film metasurface

Abstract In this article, we report classical sensing with undetected light at a wavelength of 1500 nm, detected on a silicon camera at 580 nm, using four-wave mixing from a plasmonic metasurface. The bidirectional nonlinear scattering due to inherent reflections from such thin n...

Revealing hidden nonlocality and preparation contextuality for an arbitrary input Bell inequality

Abstract In recent years, the activation of hidden nonlocality for a mixed entangled state, admitting a local model, has gained considerable interest. In this paper, we study the activation of hidden nonlocality and preparation contextuality for a class of mixed entangled states,...
