Abstract

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave. Even the interference of two plane waves, or a single inhomogeneous (evanescent) wave, provides a number of nontrivial phenomena and additional functionalities as compared to a single plane wave. Complex wavefields with inhomogeneities in the amplitude, phase, and polarization, including topological structures and singularities, underpin modern nanooptics and photonics, yet they are equally important, e.g., for quantum matter waves, acoustics, water waves, etc. Structured waves are crucial in optical and electron microscopy, wave propagation and scattering, imaging, communications, quantum optics, topological and non-Hermitian wave systems, quantum condensed-matter systems, optomechanics, plasmonics and metamaterials, optical and acoustic manipulation, and so forth. This Roadmap is written collectively by prominent researchers and aims to survey the role of structured waves in various areas of wave physics. Providing background, current research, and anticipating future developments, it will be of interest to a wide cross-disciplinary audience., Comment: 110 pages, many figures

Abstract

The HITRAN database is a compilation of molecular spectroscopic parameters. It was established in the early 1970s and is used by various computer codes to predict and simulate the transmission and emission of light in gaseous media (with an emphasis on terrestrial and planetary atmospheres). The HITRAN compilation is composed of five major components: the line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, experimental infrared absorption cross-sections (for molecules where it is not yet feasible for representation in a line-by-line form), collision-induced absorption data, aerosol indices of refraction, and general tables (including partition sums) that apply globally to the data. This paper describes the contents of the 2020 quadrennial edition of HITRAN. The HITRAN2020 edition takes advantage of recent experimental and theoretical data that were meticulously validated, in particular, against laboratory and atmospheric spectra. The new edition replaces the previous HITRAN edition of 2016 (including its updates during the intervening years). All five components of HITRAN have undergone major updates. In particular, the extent of the updates in the HITRAN2020 edition range from updating a few lines of specific molecules to complete replacements of the lists, and also the introduction of additional isotopologues and new (to HITRAN) molecules: SO, CH3F, GeH4, CS2, CH3I and NF3. Many new vibrational bands were added, extending the spectral coverage and completeness of the line lists. Also, the accuracy of the parameters for major atmospheric absorbers has been increased substantially, often featuring sub-percent uncertainties. Broadening parameters associated with the ambient pressure of water vapor were introduced to HITRAN for the first time and are now available for several molecules. The HITRAN2020 edition continues to take advantage of the relational structure and efficient interface available at www.hitran.org and the HITR

Abstract

Background There is a long-standing debate in implementation research on whether adaptations to evidence-based interventions (EBIs) are desirable in health care. If an intervention is adapted and not delivered as conceived and planned, it is said to have low fidelity. The WALK-Cph project was developed based on the assumption that involving stakeholders in co-design processes would facilitate the fidelity of an intervention to increase the mobility of acutely admitted older medical patients and its implementation in two hospitals in Denmark. The purpose of this study is to describe and analyse adaptations and modifications that were made to the co-designed WALK-Cph intervention and its implementation. Methods This study used a qualitative design. An ethnographic field study was performed using participant observations, workshops and semi-structured interviews. Data were analysed twice using the Framework Method. The first analysis was based on the frameworks from Stirman, Moore and Proctor. The second analysis, a retrospective modifications analysis, was based on the Adaptation-Impact Framework. Results Many different types of adaptations and modifications were made to the WALK-Cph intervention and its implementation plan. Most of the modifications were made on the contents of the intervention. In total, 44 adaptations and modifications were made, of which 21 were planned (adaptations) and 23 were made haphazardly (modifications). Most of the content and context adaptations and modifications made on the intervention had a mixed result regarding enhanced fidelity. The retrospective modifications analysis showed that modifications were ongoing and both situationally and contextually shaped. Conclusions Although an extensive co-design process was carried out to facilitate the fidelity of the WALK-Cph intervention, this study showed that many adaptations and modifications were still made to both the intervention and its implementation plan. It could indicate that the co-design process had a small effect or that adaptations and modifications are ongoing and both situationally and contextually shaped, which challenge the assumption and the desire to be able to plan and control changes.

Abstract

Objectives To firstly investigate the efficacy of three different dosages of home-based, knee-extensor strength exercise on isometric knee-extensor strength in patients eligible for knee replacement due to severe knee osteoarthritis, and secondly, the influence of exercise on symptoms, physical function and decision on surgery. Design Randomized dose-response trial. Setting Primary and secondary care. Participants One-hundred and forty patients eligible for knee replacement were included. Eligibility for surgery was assessed by an orthopedic surgeon specialized in knee arthroplasty. Interventions Patients were randomized to three groups; 2, 4 or 6 home-based knee-extensor exercise-sessions per week (group 2, 4 and 6 respectively) for 12 weeks (N=47/group). Exercise instruction was given by a trained physiotherapist. Main outcome measures The primary outcome was isometric knee-extensor strength. Secondary outcomes were Oxford Knee Score, Knee Osteoarthritis Outcome Score, average knee pain last week (0-10 numeric rating scale), 6-minute walk test, stair climbing test, exercise adherence and “need for surgery”. The primary endpoint was after 12 weeks of exercise (before surgery) and the secondary after surgery. Outcome assessors and patients were blinded to allocation. Results After 12 weeks of exercise, data were available for 117 patients (N=39/group). Isometric knee-extensor strength increased in all groups but intention-to-treat analysis showed no difference between the three groups in change from baseline to after 12 weeks of exercise in isometric knee-extensor muscle strength: Group 2 vs. 4 (0.009 Nm/kg [95% CI -0.15 to 0.17], P=0.913), group 2 vs. 6 (-0.03 Nm/kg [95% CI -0.18 to 0.13], P=0.725) and group 4 vs. 6 (-0.04 Nm/kg [95% CI -0.20 to 0.13], P=0.668). For the secondary outcomes a significant difference before surgery was found between group 2 and group 6 for Oxford Knee Score (4.2 [95% CI 0.6 to 7.8], P=0.02) and average knee pain last week (NRS 0-10) (-1.1 [95% -2.2 to -0.1], P=0.03) in favour of group 2. No other differences were observed before and after surgery. After the 12- week exercise intervention, 38 (32.5%) patients wanted surgery and 79 (67.5%) postponed surgery. This was independent of exercise dosage. Conclusion Knee-extensor strength increased with both 2, 4 and 6 exercise sessions per week but none of the prescribed exercise dosages were superior to the others for the primary outcome isometric knee-extensor strength after 12 weeks. Two home-based knee-extensor exercise sessions a week seems superior to six for patient-reported outcomes, and across exercise dosages, only one in three patients decided to have surgery after the coordinated home-based exercise intervention. Trial registration ClinicalTrials.gov identifier: NCT02931058, pre-registered October 10th, 2016. Protocol PubMed (PMID: 29347947). What is already known on this topic Clinical guidelines recommend exercise therapy targeting the knee-extensor muscles in patients eligible for knee replacement before surgery is considered. Exercise therapy may reduce knee osteoarthritis symptoms and impact the decision on surgery, but the dose-response relationship is not described. Exercise therapy is typically delivered as supervised programs requiring physical attendance at fixed times and often require self-payment, which may be a barrier for some patients. What this study adds Knee-extensor strength increased with 2, 4 and 6 exercise sessions per week, but none of the prescribed exercise dosages were superior to the others after 12 weeks – indicating no dose-response relationship. Two in three patients eligible for knee replacement decided to postpone knee replacement surgery after 12 weeks of home-based exercise with one simple exercise. This study successfully employed a model of coordinated care where the patients’ decision on surgical treatment was re-evaluated based on symptom changes following simple home-based exercise therapy. These findings suggest using a model of coordinated non-surgical and surgical care to improve the decision on surgery for patients eligible for knee replacement.

Abstract

Introduction: Assessment of maximal oxygen consumption (VO2max) is an important clinical tool when examining both healthy and unhealthy populations, as a low VO2max is associated with cardiovascular disease and all-cause mortality. Aim: This study investigated the accuracy of a non-exercise test for assessment of VO2max using seismocardiography (SCG). Methods: 97 participants (20-45 years, 50 males) underwent a nonexercise test using SCG at rest in the supine position (SCG VO2max) and a graded exercise test to voluntary exhaustion on a cycle ergometer with indirect calorimetry (IC VO2max). An interim analysis was applied after 50 participants had completed testing (SCG VO2max 1.0) allowing for the algorithm to be modified (SCG VO2max 2.1). Results: SCG VO2max 2.1 (n=47, test set) estimation was 3.5 pm 1.8 mlcdot min{-1}cdot kg{-1} (p < 0.001) lower compared to IC VO2max, with a Pearson correlation of r=0.65 (p < 0.0001) and a standard error of estimate of 7.1 ml·min-1 ·kg-1. The coefficient of variation between tests was 8 pm 1%. Conclusion: The accuracy of VO2max assessment using SCG requires further optimization prior to clinical application, as SCG VO2max was systematically lower than IC VO2max, and only a moderate correlation together with considerable variation were observed between tests.

Abstract

The Nordic Hamstring exercise reduces hamstring strain injuries in football and other sports, but the exercise is not well adopted in practice. Barriers from practitioners include fear of performance decrements, due to lack of specificity of the exercise with high speed running. However, in theory, increased eccentric hamstring strength could transfer to faster sprinting due to higher horizontal force production. Studies on the effect of the Nordic Hamstring exercise on performance have been conflicting and no synthesis of the evidence exists. We therefore pose the following question: does including the Nordic Hamstring exercise hamper sprint or jump performance in athletes? We will answer this question by performing a systematic review of the literature, critically appraise relevant studies, and GRADE the evidence across key outcomes and perform meta-analyses, meta-regression and subgroup analyses. In this protocol we outline the planned methods and procedures.Progress reportBesides this protocol, our data extraction form and the process of data extraction has been piloted on 3 relevant studies, along with familiarization with the Risk of Bias 2.0 tool. We have also comprised a preliminary search strategy for PubMed.Supplementary filesData Extraction Form (.pdf)Populated PRISMA-P checklist (.pdf)
