Authors: Sousa Helena , Ribeiro Oscar , Christensen Alan J. , Figueiredo Daniela 
Published: December 2021

AbstractAimThis study aimed to explore the stressors and coping strategies of adult children who care for their parents with end‐stage renal disease (ESRD) undergoing in‐centre haemodialysis.BackgroundGiven the growing number of older patients with ESRD, adult children are increasingly providing more care and assistance to their parents with this condition. However, little is still known about the experiences of caring for a parent undergoing haemodialysis.DesignA qualitative exploratory study was conducted in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines.MethodsSemi‐structured face‐to‐face interviews with nineteen adult children (44.9 ± 11.7 years old) were carried out. Data were transcribed verbatim and subjected to thematic analysis.ResultsFour stressors (managing disease and treatment‐related requirements, patients’ reaction to treatment, lack of support from family members, and additional challenges to personal and family life) and five coping strategies (active coping and planning, seeking social support for emotional use, accepting the situation as it is, venting emotions, and maintaining interests outside caring) were identified.ConclusionCaring for a parent undergoing haemodialysis is an experience with several challenges, marked by educational needs, emotional distress, lack of support from close relatives and the need to manage multiple responsibilities.Relevance to clinical practiceFindings highlight the importance of developing interdisciplinary educational and supportive interventions to support this group of caregivers. These interventions should facilitate access to disease and treatment‐related information, provide emotional support, and train coping skills to prevent burden and promote healthy adjustment to the demands of ESRD care.

AbstractBackgroundOrthostatic tremor (OT) is a rare movement disorder characterized by high‐frequency (>12 Hz) involuntary, rhythmic, sinusoidal movements affecting predominantly the limbs while standing.ObjectiveTo describe the signalment, presenting complaints, phenotype, diagnostic findings, treatment, and outcome of a large sample of dogs with OT.AnimalsSixty dogs diagnosed with OT based on conscious electromyography.MethodsMulticenter retrospective case series study. Dogs were included if they had a conscious electromyography consistent with muscle discharge frequency >12 Hz while standing.ResultsFifty‐three cases were diagnosed with primary OT (POT). Giant breed dogs represented most cases (83%; 44/53). Most dogs (79%; 42/53) were younger than 2 years of age at onset of signs, except for Retrievers which were all older than 3.5 years of age. The most common presenting complaints were pelvic limb tremors while standing (85%; 45/53) and difficulty when rising or sitting down (45%; 24/53). Improvement of clinical signs occurred in most dogs (85%; 45/53) treated medically with phenobarbital, primidone, gabapentin, pregabalin or clonazepam, but it was mostly partial rather than complete. Orthostatic tremor‐plus was seen in 7 dogs that had concurrent neurological diseases.Conclusions and Clinical ImportancePrimary OT is a progressive disease of young, purebred, giant/large‐breed dogs, which appears to begin later in life in Retrievers. Primary OT apparently responds partially to medications. Orthostatic tremor‐plus exists in dogs and can be concomitant or associated with other neurological diseases.
Diaspora formation and mobilisation: The emerging Hong Kong diaspora in the anti‐extradition bill movement
Authors: Fong Brian C. H. 
Published: December 2021

AbstractOver the years, literature studying stateless diaspora formation through a transborder social movement studies approach is growing. The recent rise of Hong Kong diaspora provides an emerging case of stateless diaspora that introduces new empirical insights into the scholarly literature. Using a mixed‐method research strategy, this study empirically investigates the formation of the Hong Kong diaspora as a ‘historically contingent process’, through which overseas Hongkongers were mobilised during the 2019–20 Anti‐Extradition Bill Movement (critical event) to join global protests (mobilising practices) by diaspora groups and activists (mobilising agents). Achieved transborder outreach across the Global North by mobilising their strong moral and cultural resources, it remains to be seen whether the emerging Hong Kong diaspora will move towards a full‐fledged, sustained identity‐based movement. The case study of Hong Kong diaspora offers new comparative insights and establishes a mixed‐method analytical framework for comparing stateless diaspora worldwide.

AbstractThis paper provides an outline of a new interdisciplinary project called FixOurFood, funded through UKRI’s ‘Transforming UK food systems’ programme. FixOurFood aims to transform the Yorkshire food system to a regenerative food system and will work to answer two main questions: (1) What do regenerative food systems look like? (2) How can transformations be enabled so that we can achieve a regenerative food system? To answer these questions, FixOurFood will work with diverse stakeholders to change the Yorkshire food system and use the learning to inform change efforts in other parts of the UK and beyond. Our work will focus on shifting trajectories towards regenerative dynamics in three inter‐related systems of: healthy eating for young children, hybrid food economies and regenerative farming. We do this by a set of action‐orientated interventions in schools and the food economy, metrics, policies and deliverables that can be applied in Yorkshire and across the UK. This article introduces the FixOurFood project and concludes by assessing the potential impact of these interventions and the importance we attach to working with stakeholders in government, business, third sector and civil society.

ObjectiveThis study aims to determine outcomes and complications in functional reconstruction of soft tissue defects after surgical resection for soft tissue sarcomas (STSs) of extremities.MethodsA retrospective chart review was performed on patients with STSs of extremities from May 2015 to April 2019 who underwent radical resection of STSs and reconstruction of soft tissue defect with free vascularized anterolateral thigh flap (FVALTP). A minimum 3‐month follow‐up was required for all the patients. Patient demographics and comorbidities, flap characteristics, postoperative complications, and time to heal were recorded. The functional outcomes of the reconstructed limbs were assessed by the Musculoskeletal Tumour Society（MSTS） scoring system.ResultsA total of 11 patients (four males and seven females) were included in the study. The mean age was 62 years (range: 29–84 years). The mean surface area was 151.4 cm2 (range: from 64 cm2 to 418cm2). The mean operation time was 126 min (range: 95–296 min). The mean follow‐up was 17.5 months (range: 6–34 months). The mean score of MSTS at last follow‐up was 26.2 (range: 12–29). Incision healed by first intention in eight patients. Incision healed by second intention in three patients. A patient who had received preoperative radiotherapy experienced delayed union. After debridement, the patient successfully got union. Another two patients experienced marginal necrosis of flap due to vascular crisis. After 3‐week dressing changes, the patients also got satisfactory union. One case suffered from vascular crisis during surgery in which the procedure was changed into skin grafting to cover resection site.ConclusionFVALTP technique can be effectively applied to the reconstruction of soft tissue defect after STSs resection. The short‐term follow‐up indicated satisfactory functional outcome and low incidence of previously known complications. It was necessary to further validate its efficacy in reconstruction of soft tissue defect after malignant extremity soft tissue sarcoma resection.

Published: December 2021

AbstractObjective: This study aimed to clarify the status of novice public health nurses’ home‐visit skills during their first year of practice.Design and sample: A one‐year longitudinal observational study was conducted with 80 novice public health nurses. The participants were recruited from the four Japanese prefectures and their affiliated municipalities selected by using stratified sampling.Measurements: Self‐administered questionnaires were distributed three times between April 2016 and March 2017, asking about home‐visit experiences, understandings of the significance of home‐visit, and the levels of home‐visit skills. Data were analyzed with paired t‐tests and Wilcoxon signed‐rank tests.Results: All of twenty skills’ self‐ratings significantly increased between the fourth and eighth months; five skills continually increased between the eighth and twelfth months. Both of Physical Assessment and Relationship Development Skills improved to the “Can do, almost by myself” level at the twelfth month; other skills remained at the “Can do, with a little advice” level.Conclusion: Although novice public health nurses improved to conducted home‐visits independently, they didn't perceive themselves as being able to do so in their first year. Therefore, through preparing guideline, organizations should provide intentional support to assist their skill acquisition during their first, and even in their second year.

AbstractObjectiveParenting support has shifted from a problem‐focused to a strengths‐based solution‐focused approach. This study surveyed public health nurses to explain their intention to provide solution‐focused parenting support in their practice.DesignThe design of this study was cross‐sectional.SampleThe initial sample included 781 public health nurses who were employed with various youth healthcare organizations in the Netherlands.MeasurementsBased on the Theory of Planned Behavior, a questionnaire was developed and administered to measure (a) behavioral, normative, and control beliefs, (b) attitudes, subjective norm, and perceived behavioral control, and (c) intention. The data were subjected to structural equation modeling.ResultsA total of 449 (57.5%) public health nurses completed questionnaires. Associations as indicated by the Theory of Planned Behavior were confirmed with the exception of that between perceived behavioral control and intention. Statistically significant paths and correlations were added. The final model accounted for 53% of the variance in the intention to perform solution‐focused parenting support.ConclusionsIn this study, public health nurses strongly intended to provide solution‐focused parenting support, thus indicating their acceptance of the approach. Their intention was predominantly associated with subjective norm.

AbstractThe modern presidency is one of administration, where presidents seek to further their own agendas by directing administrative behavior throughout the executive branch. Yet little research explores how executive agencies organize their policy processes in response to publicly articulated presidential priorities. Using two novel datasets that allow us to examine the regulatory priorities of presidents and how executive agencies organize their rulemaking processes, we find that executive agencies respond to presidential policy preferences by centralizing policymaking to the top of an agency's hierarchy, placing regulation in the hands of political appointees.
Using Extremum Seeking Control to Improve the Power Capture of Midsize Hydrostatic Wind Turbines

Published: December 2021

Abstract
Adaptive control strategies are commonly used for systems that change over time, such as wind turbines. Extremum Seeking Control (ESC) is a model-free real-time adaptive control strategy commonly used in conventional gearbox wind turbines for Maximum Power Point Tracking (MPPT). ESC optimizes the rotor power by constantly tuning the torque control gain (k) when operating below rated power. The same concept can be applied for hydrostatic wind turbines. This paper studies the use of ESC for a 60-kW hydrostatic wind turbine. First, a systematic approach to establish the ideal ESC is shown. Second, a comparison of the power capture performance of ESC versus the conventional torque control law (the kω2 law) is shown. The simulations include a timesharing power capture coefficient (Cp) to clearly show the advantages of using ESC. Studies under steady and realistic wind conditions show the main advantages of using ESC for a hydrostatic wind turbine.
Composite Adaptive Dynamic Surface Control for a Multi-DOF Hydraulic Manipulator With Disturbance Observer
Authors: Zhang Xiaofu , Shi Guanglin 
Published: December 2021

Abstract
This paper presents an adaptive dynamic surface control strategy based on composite adaptive method for a multi-DOF hydraulic manipulator with the unknown disturbance and uncertainties. The manipulator is driven by multiple hydraulic actuators so that the system can have the advantages of the hydraulic system such as the high-power density. Dynamic characteristics of the hydraulic system have a non-negligible impact on the performance of the manipulator. Considering the hydraulic actuator dynamics, the mathematical model of the hydraulic manipulator is derived at first. The dynamic model is high nonlinear, and has unmatched and matched disturbances and parameter uncertainties such as the mass and length of each articulated arm and the elastic modulus of hydraulic oil. Then, a composite adaptive control law is designed to estimate the uncertain parameters of the hydraulic manipulator, and a disturbance observer is explored to compensate the unknown disturbances without acceleration measurement that generally introduces the high noise into the system. Besides, the dynamic surface controller is proposed to account for the system nonlinearity and stabilize the closed-loop system. Finally, comparative experiments of the position tracking of the hydraulic manipulator are performed to verify the effectiveness of the proposed control strategy.
Efficient Control of a Switched Inertance Hydraulic Converter With a Time-Varying Load

Published: December 2021

Abstract
Switched inertance hydraulic converters (SIHC) are new digital hydraulic devices which provide an alternative to conventional proportional or servo valve-controlled systems in hydraulic fluid power. SIHCs can adjust and control flow and pressure by means of using digital control signals that do not rely on throttling the flow and dissipation of power, and provide hydraulic systems with high-energy efficiency, good controllability, and insensitivity to contamination. A flow booster is one configuration of SIHCs which can deliver more flow than the supply flow. In this article, the loading effects of SIHCs are investigated by applying a time-varying load on the flow booster. A control system consisting of a PI controller and a switching frequency optimizer was designed to operate a flow booster at its optimal switching frequencies and switching ratios to maximize system efficiency when the load varies. Simulated results showed that the flow booster with the proposed controller has very good dynamic response and can be operated at an average efficiency of 70% with a time-varying load. Compared with only using a PI controller, the proposed controller can improve the overall efficiency by up to 20%. As time-varying loading conditions are commonly found in hydraulic applications, this work constitutes an important contribution to the design and development of high-efficiency SIHCs.
Design and Efficiency Analysis of Closed Loop Pump Controlled Circuit Hydraulic Lifting System of Wheel Loaders Based on Gravity Self-Balancing Hydraulic Cylinder
Authors: Wang Xiangyu , Zhang Hongjuan , Zhang Xiaogang , Quan Long 
Published: December 2021

Abstract
In the hydraulic lifting systems of wheel loaders, the valve controlled systems are used to drive the hydraulic cylinder to complete frequent lifting and falling operations. The gravitational potential energy of the lifting system, accumulated in the lifting process, is converted into heat energy through the throttling port of the valve during the falling processes, which results in significant throttling loss and severe system overheating. To solve the problems, a potential energy regeneration and utilization system is proposed, where the closed loop pump controlled circuit based on the gravity self-balancing hydraulic cylinder is adopted to eliminate throttling loss, and the gravity self-balancing chamber of the cylinder is directly connected with accumulator to recycle gravity potential energy. In the research, the structure and working principle of the proposed hydraulic system is analyzed first, then the co-simulation model and the test prototype are established to investigate the working and energy characteristics of the proposed system. Test results indicate that, compared with the traditional valve controlled hydraulic system, 58.9% energy consumption reduction can be expected for the hydraulic pump by adopting the proposed system under the same working condition.

Published: December 2021

Abstract
Hydrostatic and hydro-mechanical transmissions (HSTs and HMTs, respectively) are commonly used in off-highway vehicles. While both transmission technologies can provide continuously variable torque or speed ratios, they suffer from poor efficiencies and limited operating ranges. Electric variable transmissions (EVTs), in contrast, offer complementary strengths via higher efficiencies at low forward and reverse speeds, full torque from zero to full power, and increased control capabilities. While HST, HMT, and EVT powertrain architectures are not novel, the authors are not aware of work integrating these technologies into hydro-electro-mechanical (HEMT) transmission architectures. Thus, this research aimed to develop a physical modeling methodology to explore different power-split transmission technologies using hydraulic, electrical, and mechanical pathways to understand how the complementary nature of the technologies could be used for overall power transmission performance. Steady-state modeling was performed using the Modelica® (Modelica Association) modeling language in the Dymola (Dassault Systems®) integrated development environment. Overall efficiency vs. output speed was presented for HMT, EMT, and HEMT input-coupled architectures, including circulating power considerations. This research extends the state-of-the-art of off-road powertrain technologies by providing the literature an exemplar modeling of HEMT coupling techniques, system integration, and power flow architectures in Modelica® modeling language.

Published: December 2021

Abstract
Solenoid valves are enabling components for flow and motion control in fluid power systems. It is important for reduction of a machinery’s “off” time if quick fault diagnosis of solenoid valves can be performed on site. Traditional fault diagnosis usually involves signal convolution, machine learning, or fuzzy logics, which can achieve over 90% accuracy but are all computationally intensive, and may be difficult to achieve rapid analysis on site with portable electronics. Among various kinds of faults of solenoid valves, the most common ones are the leakage caused by poor sealing between the poppet and the sleeve, stiction caused by foreign matters in the valve body, or solenoid failure. This paper proposed to simplify the fault diagnosis process by derivation of analytical models of fault characteristics of solenoid on-off valve based on electromagnetics and lumped mass fluid mechanics. Firstly, according to the structure of the solenoid valve, the electromagnetic model of the armature, solenoid, and the air gap is deduced. Secondly, five features from two sensor data are constructed. Fault isolation matrix, tested features are also defined. Thirdly, experimental system was setup to acquire the key threshold values for membership function definition. Finally, two validation tests were conducted and the initial results showed that the proposed method is capable of detecting solenoid valve stiction of various degrees.
