Position Tracking Constrained Adaptive Output Feedback Control of Robotic Manipulators
Authors: Gul Samet , Zergeroglu Erkan , Tatlicioglu Enver 
Published: August 2022

Abstract
This work presents the design and the corresponding stability analysis of a model-based, joint position tracking error constrained, adaptive output feedback (OFB) controller for robot manipulators. Specifically, provided that the initial joint position tracking error starts within a predefined region, the proposed controller algorithm ensures that the joint tracking error remains inside this region and asymptotically approaches zero, despite the lack of joint velocity measurements and uncertainties associated with the system dynamics. The constraint imposed on the position tracking error term ensures predictable overshoot for the overall system and enables a predetermined transient performance. The need for the joint velocity measurements is removed via the use of a surrogate filter formulation in conjunction with the use of desired model compensation. The stability and the convergence of the closed-loop system are proved via a barrier Lyapunov function (BLF)-based argument. Extensive numerical simulations and experimental studies performed on a two-link, direct-drive robotic manipulator are provided to illustrate the feasibility and effectiveness of the proposed method.
Experimental Investigation and Optimizing the Parameters of a Solar Air Heater Having Broken Arc-Shaped Ribs Using Hybrid Entropy-VIKOR Technique

Published: August 2022

Abstract
In this article, thermal performance of a solar air heater (SAH) having broken arc-shaped ribs has been investigated experimentally, and then, performance parameters have been optimized. Study reveals that the use of artificial roughness enhances both heat transfer rate and pumping power requirement, and hence, the overall performance of solar air heater increases. Thus, it is imperative to optimize the performance-defining criteria viz. Nusselt number enhancement ratio, friction factor enhancement ratio, and thermohydraulic performance parameter, to propose an optimal set of flow and roughness parameters. The hybrid entropy-VIKOR technique has been employed to outline the optimal set of parameters using performance-defining criterions, to obtain maximum profit with the minimum incurred cost. The optimal set of parameters attained using entropy-VIKOR approach among all the alternatives is as follows: relative gap width = 4, relative roughness pitch = 10, and arc angle = 45 deg at Reynolds number = 9000.

Published: August 2022

Medial epicondylalgia is a repetitive stress condition. The aim of this study was to assess whether Kinesio taping offers any superiority over athletic taping for chronic medial epicondylalgia management. The results show statistically significant differences in isokinetic and patient self-reported variables between each group: (a) Group A: Kinesio tape with rehabilitation; (b) Group B: athletic taping with rehabilitation; and (c) group C: only rehabilitation. Although no significant differences in preintervention group assessments (p > .05) were found, only Group (A) showed statistically significant posttreatment improvements. Kinesio taping over athletic taping appears effective for treating chronic medial epicondylalgia and facilitating pain reduction and isokinetic improvements.

Abstract
An overview of modern studies on ice cores from nonpolar regions of the Earth is presented. As an example of complex research on the territory of Russia, a description of the main results of the study of ice cores from Elbrus is given. The seasonally resolved data on the chemical and isotopic composition of the Elbrus core cover 1774–2009 reconstructed various aspects of atmospheric pollution in southeastern Europe from preindustrial times to the present day. The necessity of studying several ice cores from different regions to reconstruct the composition of the atmosphere, its pollution, and the reaction of vegetation to climate change and forest fires in Russia is shown.

ObjectivesMultifactorial interventions, which involve assessing an individual’s risk of falling and providing treatment or onward referral, require coordination across settings. Using a mixed-methods design, we aimed to develop a process map to examine onward referral pathways following falls risk assessment in primary care.SettingPrimary care fall risk assessment clinics in the South of Ireland.ParticipantsFocus groups using participatory mapping techniques with primary care staff (public health nurses (PHNs), physiotherapists (PT),and occupational therapists (OT)) were conducted to plot the processes and onward referral pathways at each clinic (n=5).MethodsFocus groups were analysed in NVivo V.12 using inductive thematic analysis. Routine administrative data from January to March 2018 included details of client referrals, assessments and demographics sourced from referral and assessment forms. Data were analysed in Stata V.12 to estimate the number, origin and focus of onward referrals and whether older adults received follow-up interventions. Quantitative and qualitative data were analysed separately and integrated to produce a map of the service.ResultsNine staff participated in three focus groups and one interview (PHN n=2; OT n=4; PT n=3). 85 assessments were completed at five clinics (female n=69, 81.2%, average age 77). The average number of risk factors was 5.4 out of a maximum of 10. Following assessment, clients received an average of three onward referrals. Only one-third of referrals (n=135/201, 33%) had data available on intervention receipt. Primary care staff identified variations in how formally onward referrals were managed and barriers, including a lack of client information, inappropriate referral and a lack of data management support.ConclusionChallenges to onward referral manifest early in an integrated care pathway, such as clients with multiple risk factors sent for initial assessment and the lack of an integrated IT system to share information across settings.

Published: August 2022

IntroductionTotal mesorectal excision is the standard of care for rectal cancer, which can be performed using open, laparoscopic, robot-assisted and transanal technique. Large prospective (randomised controlled) trials comparing these techniques are lacking, do not take into account the learning curve and have short-term or long-term oncological results as their primary endpoint, without addressing quality of life, functional outcomes and cost-effectiveness. Comparative data with regard to these outcomes are necessary to identify the optimal minimally invasive technique and provide guidelines for clinical application.Methods and analysisThis trial will be a prospective observational multicentre cohort trial, aiming to compare laparoscopic, robot-assisted and transanal total mesorectal excision in adult patients with rectal cancer performed by experienced surgeons in dedicated centres. Data collection will be performed in collaboration with the prospective Dutch ColoRectal Audit and the Prospective Dutch ColoRectal Cancer Cohort. Quality of life at 1 year postoperatively will be the primary outcome. Functional outcomes, cost-effectiveness, short-term outcomes and long-term oncological outcomes will be the secondary outcomes. In total, 1200 patients will be enrolled over a period of 2 years in 26 dedicated centres in the Netherlands. The study is registered at https://www.trialregister.nl/9734 (NL9734).Ethics and disseminationData will be collected through collaborating parties, who already obtained approval by their medical ethical committee. Participants will be included in the trial after having signed informed consent. Results of this study will be disseminated to participating centres, patient organisations, (inter)national society meetings and peer-reviewed journals.

Published: August 2022

ObjectiveHealthcare provider (HCP) burnout is on the rise with electronic medical record (EMR) use being cited as a factor, particularly with the rise of the COVID-19 pandemic. Burnout in HCPs is associated with negative patient outcomes, and, therefore, it is crucial to understand and address each factor that affects HCP burnout. This study aims to (a) assess the relationship between EMR use and burnout and (b) explore interventions to reduce EMR-related burnout.MethodsWe searched MEDLINE (Ovid), CINAHL and SCOPUS on 29 July 2021. We selected all studies in English from any publication year and country that discussed burnout in HCPs (physicians, nurse practitioners and registered nurses) related to EMR use. Studies must have reported a quantitative relationship to be included. Studies that implemented an intervention to address this burnout were also included. All titles and abstracts were screened by two reviewers, and all full-text articles were reviewed by two reviewers. Any conflicts were addressed with a third reviewer and resolved through discussion. Quality of evidence of all included articles was assessed using the Quality Rating Scheme for Studies and Other Evidence.FindingsThe search identified 563 citations with 416 citations remaining after duplicate removal. A review of abstracts led to 59 studies available for full-text assessment, resulting in 25 studies included in the scoping review. Commonly identified associations between EMR-related burnout in HCPs included: message and alert load, time spent on EMRs, organisational support, EMR functionality and usability and general use of EMRs. Two articles employed team-based interventions to improve burnout symptoms without significant improvement in burnout scores.Conclusions and relevanceCurrent literature supports an association between EMR use and provider burnout. Very limited evidence exists for burnout-reducing interventions that address factors such as time spent on EMRs, organisational support or EMR design.

Published: August 2022

ObjectiveTo reduce the incidence of metabolic bone disease (MBD) among very low birthweight (VLBW) infants admitted to neonatal intensive care unit from baseline of 35% by 50% over 2 years by implementing a quality improvement (QI) initiative.MethodsA multidisciplinary QI team used evidence-based interventions and the healthcare improvement model to reduce MBD rate in VLBW infants. The specific interventions included routine enteral supplementation of calcium and phosphorus using Human Milk Fortifier (HMF) to expressed breast milk by day 14 of life (Plan/Do/Study/Act (PDSA) cycle 1), parenteral and early enteral supplementation of calcium and phosphorus (PDSA cycles 2 and 3). We included VLBW infants admitted within the study period at birth and excluded babies with congenital malformations, skeletal disorders and those who died before 2 weeks of age. Compliance with adding HMF by day 14, compliance with adding calcium and phosphorus in total parenteral nutrition (TPN) from day 1 of life and compliance with starting HMF when the baby reached 100 mL/kg/day of feeds were used as process indicators. The incidence of MBD was used as an outcome indicator during the study. The incidence of MBD was tracked using the Statistical Process Control methodology.ResultsThe baseline MBD rate in 2015 was 35%. After the first PDSA cycle, 20% developed MBD (p=0.02). The same was sustained for a period of 1 year with the rate of 22%. After the second and third PDSA cycles, there was a drop in the MBD rate to 17%, and sustained for 3 months with 21%.ConclusionImplementation of QI initiatives decreased the MBD rate from 35% to <20%. Early parenteral calcium and phosphorus supplementation in TPN and optimising enteral supplementation with multicomponent fortifiers appear to have significant reduction in the incidence of MBD.

Published: August 2022

ObjectiveArea-level socioeconomic factors are known to associate with chances to survive out-of-hospital cardiac arrest (OHCA survival). However, the relationship between individual-level socioeconomic factors and OHCA survival in men and women is less established. This study investigated the association between individual-level income and OHCA survival in men and women, as well as its contribution to outcome variability and mediation by resuscitation characteristics.MethodsA cross-sectional cohort study using data from a Dutch community-based OHCA registry was performed. We included 5395 patients aged≥25 years with OHCA from a presumed cardiac cause. Household income, derived from Statistics Netherlands, was stratified into quartiles. The association between survival to hospital discharge and household income was analysed using multivariable logistic regression adjusting for age, sex and resuscitation characteristics.ResultsOverall women had lower household income than men (median €18 567 vs €21 015), and less favourable resuscitation characteristics. Increasing household income was associated with increased OHCA survival in both men and women in a linear manner (Q4 vs Q1: OR 1.63 95% CI (1.24 to 2.16) in men, and 2.54 (1.43 to 4.48) in women). Only initial rhythm significantly changed the ORs for OHCA survival with>10% in both men and women. Household income explained 3.8% in men and 4.3% in women of the observed variance in OHCA survival.ConclusionBoth in men and women, higher individual-level household income was associated with a 1.2-fold to 2.5-fold increased OHCA survival to hospital discharge, but explained only little of outcome variability. A shockable initial rhythm was the most important resuscitation parameter mediating this association. Our results do not support the need for immediate targeted interventions on actionable prehospital resuscitation care characteristics.

Published: August 2022

ObjectivesUsing Mendelian randomisation (MR), we examined whether childhood body size affects risk of rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), gout and systemic lupus erythematosus (SLE) after accounting for the effect of adult body size.MethodsGenetic instruments for childhood (age 10 years) and adult body size were derived using data from 453 169 individuals from the UK Biobank study (313 and 580 variants respectively), which have been previously validated using body mass index data from three independent populations. Genome-wide association data comprised 22 350 RA, 9069 AS, 3609 PsA, 13 179 gout and 5201 SLE cases. For each outcome, we conducted univariable MR to estimate the total effects of childhood and adult body size, and multivariable MR to examine the independent effect of childhood body size after accounting for adult body size.ResultsGenetically predicted childhood body size had a total effect on risk of PsA (OR 2.18 per change in body size category; 95% CI 1.43 to 3.31), gout (OR 2.18; 95% CI 1.43 to 3.31) and SLE (OR 2.44; 95% CI 1.14 to 5.22), but not RA (OR 0.95; 95% CI 0.70 to 1.29) or AS (OR 0.96; 95% CI 0.61 to 1.52). After accounting for adult body size, the direct effect of childhood body size was little changed for PsA (OR 1.92; 1.14 to 3.25) and SLE (OR 2.69; 1.24 to 5.87) but was attenuated for gout (OR 1.40; 95% CI 0.94 to 2.09).ConclusionsOur findings suggest that, for PsA and SLE, the risk conferred from having a larger body size during childhood may not be fully reversable even when a healthy size is achieved in adulthood.

Published: August 2022

ObjectiveThe contribution of patient research partners (PRPs) is well established in EULAR recommendation development. However, in observational and registry studies, PRP involvement is not well-defined and remains limited.MethodsBased on a round table discussion during the EULAR Registries and Observational Drug Studies (RODS) meeting in 2019, a mixed methods study was undertaken, including a survey to RODS participants and EULAR PRPs and focus groups with volunteers from the survey. An inductive thematic analysis approach was applied to qualitative data and descriptive statistics to survey data.ResultsWe retrieved 45 survey responses and ran 3 focus groups with a total of 17 participants. The notion of PRP involvement in research was positively perceived by PRPs and the wider academic rheumatology community. There is universal agreement that PRP involvement in registry research is low and inclusion in different parts of the research cycle is limited. Potential benefits of PRP involvement include: input on the research objectives based on patients’ needs, advice and support regarding recruitment and retention strategies, obtaining patient views on analysis and interpretation, and assistance in disseminating results. Researchers and PRPs highlighted that education, inclusion of PRPs with diverse backgrounds and a welcoming environment as important facilitators for PRP involvement. On the other hand, preconceptions of researchers and insufficient budget allocation have been identified as barriers.ConclusionThere is an unmet need to involve PRPs in registries and observational studies and to better define their required input during all research stages. This study provides suggestions for successful PRP integration.

AbstractIn this study, the conceptual design and physics simulations of a near-field Water-based Liquid Scintillator (WbLS) detector placed 100 m from the Akkuyu Nuclear Power Plant (ANPP), currently under construction and aiming at being Turkey’s first nuclear power plant, is presented. The ANPP is an excellent opportunity for neutrino studies and the development of an R &D program for neutrino detectors in Turkey. The Reactor Neutrino Experiments of Turkey (RNET) program includes a compact detector with a 2.5-ton volume of WbLS and a $$\sim $$
∼
30% photo-coverage, and the program is planned to be expanded with a medium-size 30-ton detector that will be an international testbed for WbLS and new detector technologies through low energy neutrino studies. In the following, the focus will be on the smaller $$\sim $$
∼
2.5 ton detector, instrumented with 8-in. high quantum efficiency PMTs and two layers of cosmic veto paddles, covering all sides of the detector, to track and veto cosmic particles. Inverse Beta Decay (IBD) events from electron anti-neutrinos generated in the reactor core are simulated using the RAT-PAC simulation package and several liquids with different percentages of Liquid Scintillator (LS) and Gadolinium (Gd) are investigated.
A proposal for the Yang–Mills vacuum and mass gap
Authors: Metaxas Dimitrios 
Published: August 2022

AbstractI examine a set of Feynman rules, and the resulting effective action, that were proposed in order to incorporate the constraint of Gauss’s law in the perturbation expansion of gauge field theories. A set of solutions for the Lagrangian and Hamiltonian equations of motion in Minkowski space-time, as well as their stability, are investigated. A discussion of the Euclidean action, confinement, and the strong-CP problem is also included. The properties and symmetries of the perturbative and the confining vacuum are explored, as well as the possible transitions between them, and the relations with phenomenological models of the strong interactions.
Coherent states and particle scattering in loop quantum gravity
Authors: Vaid Deepak , Suresh Devadharsini 
Published: August 2022

AbstractQuantum field theory provides us with the means to calculate scattering amplitudes. In recent years a dramatic new development has lead to great simplification of such calculations. This is based on the discovery of the “amplituhedron” in the context of scattering of massless gauge bosons in Yang–Mills theory. One of the main challenges facing Loop Quantum Gravity is the lack of a clear description of particle scattering processes and a connection to flat space QFT. Here we show a correspondence between the space of kinematic data of the scattering N massless particles and U(N) coherent states in LQG. This correspondence allows us to provide the outlines of a theory of quantum gravity based upon the dynamics of excitations living on the the positive Grassmannian.
Natural hydrogen seeps as analogues to inform monitoring of engineered geological hydrogen storage

Published: August 2022

Abstract

Engineered geological porous media hydrogen storage must be designed to ensure secure storage, and use appropriate monitoring, measurement and verification tools. Here, we identify and characterize 60 natural hydrogen seeps as analogues for potential leakage from engineered storage reservoirs to consider implications for monitoring. We report and compare the geological and environmental setting; seepage mode (dry gas/associated with water); co-released gases; seep rates and areal fluxes; temporal variation; seep structure; gas source; and composition. Seep characteristics are determined by local geological and hydrological conditions, specifically whether hydrogen gas is seeping through soils and unconsolidated sediments, fractured bedrock or into water. Hydrogen is typically co-emitted with other gases (CO
2
, CH
4
, N
2
) with CH
4
, the most common co-emitted gas. The structural controls on seep location and characteristics are similar between hydrogen and CO
2
seeps. However, compared to CO
2
, hydrogen is more readily dispersed when mixing with air and hydrogen is more prone to being consumed or transformed via biotic or abiotic reactions, and so the quantity of leaked hydrogen can be greatly attenuated before seeping. Monitoring approaches should therefore be tailored to the local geology and hydrological conditions, and monitoring approaches to detect hydrogen and associated gases would be appropriate.
