Introduction It is well documented that the prevalence of venous leg ulcers (VLUs) increasing, coinciding with an ageing population. Accurate global VLUs difficult to estimate due range methodologies used in studies and accuracy reporting. (1) Venous ulceration most common type a significant clinical problem, affecting approximately 1% population 3% people over 80 years age (2) westernised countries. Moreover, predicted escalate dramatically, as are living longer, often multiple...
Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers promising route towards large scale distributed computing. Ideal candidates for coherent qubit interconversion are optically active spins, magnetically coupled to superconducting resonator. We report on an on-chip cavity QED experiment with anisotropic Er(3+)∶Y2SiO5 crystals demonstrate collective strong coupling of rare-earth spins lumped element Moreover, the electron spin resonance relaxation dynamics...
Superconducting microwave resonators are reliable circuits widely used for detection and as test devices material research. A determination of their external internal quality factors is crucial many modern applications, which either require fast measurements or operate in the single photon regime with small signal to noise ratios. Here, we use circle fit technique diameter correction provide a step by guide implementing an algorithm robust fitting calibration complex resonator scattering...
Background An increasing number of health care professionals are using mobile apps. The mHealth App Usability Questionnaire (MAUQ) was designed to evaluate the usability apps by patients and providers. However, this questionnaire is not available in French. Objective This study aims translate (from English Canadian French), cross-culturally adapt, initiate validation original version MAUQ for stand-alone used French-speaking Methods A cross-cultural research a well-established method...
We report electron spin resonance spectroscopy measurements performed at millikelvin temperatures in a custom-built spectrometer comprising superconducting micro-resonator $7$ GHz and Josephson parametric amplifier. Owing to the small ${\sim}10^{-12}\lambda^3$ magnetic resonator mode volume low noise of amplifier, sensitivity reaches $260\pm40$ spins$/$echo $65\pm10$ $\mathrm{spins}/\sqrt{\text{Hz}}$, respectively.

Introduction Chronic venous leg ulcer (VLU) healing is a complex clinical problem. It requires intervention from skilled, costly, multidisciplinary wound-care teams, working with patients to manage their care. Compression therapy has been shown help heal ulcers and reduce recurrence, some evidence suggesting the value of exercise as well. These activities require health education literacy (HL) must process, understand consistently apply information for successful self-management. Research...
