Design and performance of a magnetic bottle electron spectrometer for high-energy photoelectron spectroscopy.

We describe the design and performance of a magnetic bottle electron spectrometer (MBES) for high-energy electron spectroscopy. Our design features a 2 m long electron drift tube and electrostatic retardation lens, achieving sub-electronvolt (eV) electron kinetic energy resolution for high energy (several hundred eV) electrons with a close to 4π collection solid angle. A segmented anode electron detector enables the simultaneous collection of photoelectron spectra in high resolution and high collection efficiency modes.

What are the attitudes and perceptions of general practitioners about the role of nurse practitioners in the community care setting: A scoping review.

Background: The Nurse Practitioner role in Australia is slowly expanding, with a well-established body of evidence supporting their introduction. Yet, there is a lack of consistent support from the medical profession for this role. Nurse Practitioners wishing to work in the community setting may, therefore, experience resistance from General Practitioners.

Suppression of Huntington's Disease Somatic Instability by Transcriptional Repression and Direct CAG Repeat Binding.

Huntington's disease (HD) arises from a CAG expansion in the () gene beyond a critical threshold. A major thrust of current HD therapeutic development is lowering levels of mutant mRNA (m) and protein (mHTT) with the aim of reducing the toxicity of these product(s). Human genetic data also support a key role for somatic instability (SI) in 's CAG repeat - whereby it lengthens with age in specific somatic cell types - as a key driver of age of motor dysfunction onset.

Putting the squeeze on valence tautomerism in cobalt-dioxolene complexes.

Molecules that can reversibly switch between electronic states under an external stimulus are of interest to numerous applications. Complexes of open shell metal ions with redox active ligands undergo valence tautomerism, resulting in magnetic, colour and structural switching, relevant to data storage and actuators. However, the precise structural changes occurring during valence tautomerism in the solid state are unclear due to the lack of atomic-resolution characterization.
