Ultraviolet spectroscopy has been implemented for over thirty years to monitorvolcanic SO₂ emissions. These data have provided valuable information concerningunderground magmatic conditions, which have been of utility in eruption forecastingefforts. During the last decade the traditionally used correlation spectrometers have beenupgraded with miniature USB coupled UV spectrometers, opening a series of exciting newempirical possibilities for understanding volcanoes and their impacts upon the atmosphere.Here we review these technological developments, in addition to the scientific insightsthey have precipitated, covering the strengths and current limitations of this approach.

N2GNet tracks gait performance from subthalamic neural signals in Parkinson's disease.
NPJ Digit Med

Adaptive deep brain stimulation (DBS) provides individualized therapy for people with Parkinson's disease (PWP) by adjusting the stimulation in real-time using neural signals that reflect their motor state. Current algorithms, however, utilize condensed and manually selected neural features which may result in a less robust and biased therapy. In this study, we propose Neural-to-Gait Neural network (N2GNet), a novel deep learning-based regression model capable of tracking real-time gait performance from subthalamic nucleus local field potentials (STN LFPs).

Estimating spatiotemporal maps of greenhouse gases (GHGs) is important for understanding climate change and developing mitigation strategies. However, current methods face challenges, including the coarse resolution of numerical models, and gaps in satellite data, making it essential to improve the spatiotemporal estimation of GHGs. This study aims to develop an advanced technique to produce high-fidelity (1 km) maps of CO and CH over the Arabian Peninsula, a highly vulnerable region to climate change.

January 2025
Socio-Medical Sciences Department, Erasmus School of Health Policy & Management, Erasmus University Rotterdam, Rotterdam, The Netherlands.
Background: Rehabilitation technology is a growing field, but the sustainable implementation of these technologies, particularly in home settings, is lacking. The aim of this study was to explore the factors influencing the uptake of stroke rehabilitation technology among various stakeholders, including developers, healthcare professionals, individuals who had strokes, strategic experts, management and innovation staff, health insurers, and the National Health Care Institute.
Methods: In total, 22 semi-structured interviews were conducted with a purposive stakeholder sample.
Effects of peroxidized soybean oil on growth and energy digestibility in broilers.

Department of Animal Science, University of Illinois, Urbana, IL 61801, USA.
Peroxidized lipids have been shown to reduce broiler performance whereupon it was theorized that dietary peroxide value (PV) plus anisidine value (AnV) may be predictive of broiler performance. In experiment (EXP) 1, 64 pens (8 broilers/pen) were fed diets containing 8 levels of peroxidized soybean oil (SO). Broilers were fed diets from 7 to 35 d of age with 8 replications per dietary treatment.

BMC Public Health
January 2025
Grounded Research Hub, Rotherham Doncaster and South Humber NHS Foundation Trust, Doncaster, DN4 8QN, UK.
Background: Households in areas of socio-economic deprivation are more likely to consume diets low in fruit and vegetables. Fresh Street is a place-based fruit and vegetable voucher scheme with vouchers redeemable with local independent (non-supermarket) vendors. Paper vouchers are offered to all households in a geographical area regardless of household type, size, or income with no requirement to demonstrate need.
