The North Wyke Farm Platform: Eddy Covariance Greenhouse Gas Data

The North Wyke Farm Platform (NWFP) was established in 2010 to study and improve grassland livestock production at the farm-scale. The NWFP uses a combination of environmental sensors, routine field and lab-based measurements, and detailed management records to monitor livestock and crop production, emissions to water, emissions to air, soil health, and biodiversity. The rich NWFP datasets help researchers to evaluate the effectiveness of different grassland (and arable) farming systems, which in turn, contributes to the development of sustainable, resilient and net zero land management strategies. This document serves as a user guide to the greenhouse gas data captured using Eddy Covariance analysers and is associated with other dedicated user guides that detail the design, establishment and development of the NWFP, field events, and the quality control process of datasets

Theory of tunneling spectroscopy of normal metal/ferromagnet/spin-triplet superconductor junctions

We study the tunneling conductance of a ballistic normal metal / ferromagnet / spin-triplet superconductor junction using the extended Blonder-Tinkham-Klapwijk formalism as a model for a $c$-axis oriented Au / SrRuO$_{3}$ / Sr$_{2}$RuO$_{4}$ junction. We compare chiral $p$-wave (CPW) and helical $p$-wave (HPW) pair potentials, combined with ferromagnet magnetization directions parallel and perpendicular to the interface. For fixed $\theta_{M}$, where $\theta_{M}$ is a direction of magnetization in the ferromagnet measured from the $c$-axis, the tunneling conductance of CPW and HPW clearly show different voltage dependencies. It is found that the cases where the $d$-vector is perpendicular to the magnetization direction (CPW with $\theta_{M} = \pi/2$ and HPW with $\theta_{M} = 0$) are identical. The obtained results serve as a guide to determine the pairing symmetry of the spin-triplet superconductor Sr$_{2}$RuO$_{4}$.Comment: 12 pages, 7 figures. There is also a supplementary (not uploaded

Ground penetrating radar at work: A realistic perspective on utility surveying in the Netherlands through a comprehensive ground-truth dataset

This dataset provides a comprehensive compilation of Ground Penetrating Radar (GPR) surveys across 125 utility surveying activities in the Netherlands. The dataset details the specific use of GPR in each authentic real-life utility surveying activity, whether employed independently or as a complementary tool alongside existing surveying methods, with or without post-processing. The dataset includes 959 radargrams, ground-truth information obtained from trial trenches, and an inventory of construction, geophysical, infrastructural, and technical features. The GPR utilised in all activities is an air-coupled radar with a 500 MHz frequency antenna, a GNSS RTK positioning system, and a measuring wheel encoder. This ground-truth dataset provides researchers with a valuable resource to further assess the practical efficacy of GPR as a utility surveying method, refine radargram processing algorithms and techniques, and explore the possibilities of predictive modelling

Transitions in Parkinson's disease in primary care: Protocol of a longitudinal mixed methods study

Introduction: Parkinson's disease affects many aspects of the lives of patients and their relatives. Patients must adapt continuously to disabilities that necessitate changes in (medical) support, such as domestic adjustments, involvement of (non) professional caregivers or admission to hospital. Such changes mark a transition: a transfer of a patient between levels or locations of care. Transitions are likely to be multifold and complex, given that Parkinson's disease care extends across all echelons of healthcare. Patients and relatives are vulnerable during a transition, which imposes risks for their safety and quality of life. Guidance by the general practitioner, who knows the preferences of the patient, can help to overcome challenges associated with a transition. However, patient-centred primary care requires insight into the transitions patients with Parkinson's disease encounter. We aim to examine these transitions and the way patients, relatives and general practitioners experience them and cope with them. Moreover, we will study the patients' expectations of their general practitioner during a transition and the general practitioners' views on their role. Methods and analysis: A longitudinal mixed methods study will be conducted, using qualitative research methods combined with quantitative data as a validated questionnaire on quality of life. Patients will be asked to make a video diary every 2 weeks for a period of 1 year. Once they encounter a transition, patients and their general practitioners will be interviewed to identify causes and consequences of the transition. The verbatim transcripts of the videos and interviews will be analysed according to the principles of constant comparative analysis. Ethics and dissemination: Ethical approval was not needed according to Dutch legislation. Informed consent of patients, relatives and general practitioners will be obtained. We will disseminate the results in peer-reviewed journals, at research conferences and on the website of the Dutch Parkinson's Disease Association

Tunable critical field in Rashba superconductor thin-films

The upper critical field in type II superconductors is limited by the Pauli paramagnetic limit. In superconductors with strong Rashba spin-orbit coupling this limit can be overcome by forming a helical state. Here we quantitatively study the magnetic field-temperature phase diagram of finite-size superconductors with Rashba spin-orbit coupling. We discuss the effect of finite size and shape anisotropy. We demonstrate that the critical field is controllable by intrinsic parameters such as spin-orbit coupling strength and tunable parameters such as sample geometry and applied field direction. Our study opens new avenues for the design of superconducting spin-valves.Comment: 5 pages, 4 figures, supplemental material
