Published: June 2022

AbstractParameter estimation for solar photovoltaic (PV) models is a challenging issue due to the complex nonlinear multivariable of the current‐voltage and power‐voltage characteristics. In this article, an improved heap‐based algorithm (IHBA) is proposed to improve the performance of a recently published algorithm called heap‐based algorithm (HBA). The HBA's performance is enhanced by applying an effective exploitation feature to boost the searching around the leader position with the goal of enhancing its global search capabilities and avoiding becoming trapped in a local optimum. The proposed IHBA and the standard HBA are developed considering the practical limits of the electrical parameters of PV models to minimize the root mean square error (RMSE) between the experimental and simulated results. The numerical analyses for the PVM‐752GaAs PV module including single‐diode model (SDM), double‐diode model (DDM) and triple‐diode model (TDM) are investigated to estimate five, seven, and nine electrical parameters of these models, respectively. Besides, different recent optimization techniques are simulated with fair comparisons, which are forensic‐based investigation (FBI), equilibrium optimizer (EO), Jellyfish Search (JFS), HBA, Marine Predator Algorithm (MPA) and Enhanced MPA (EMPA), and are compared with the proposed IHBA. Several separate runs are illustrated for the proposed IHBA in comparison with others, whereas the whisker box plot and T‐tests are activated to evaluate their effectiveness metrics. The simulation results derive higher superiority of the proposed IHBA with the minimum RMSE objective and standard deviation of (0.000228 and 3.7 × 106), (0.000184 and 1.93 × 105) and (0.000017 and 2.11 × 105) for SDM, DDM, and TDM, respectively, with respect to the standard HBA, other recent and reported optimization techniques. Additionally, the P‐indicator is applied in this study to illustrate the evidence for the alternative hypothesis. Small values of the P‐indicator for the proposed IHBA are obtained compared to the standard HBA and other recent optimization techniques, where IHBA achieves p‐value of 1.0336 × 1017, 4.037 7× 1011 and 2.1490 × 1010 for SDM, DDM and TDM, respectively. The H‐value is always one which elucidates that the hypothesis probability is not more than 5% for all algorithms for SDM, DDM and TDM. Moreover, the proposed IHBA demonstrates higher efficiency as it provides the first ranks in the confidence interval values compared with other algorithms. Furthermore, the proposed IHBA is significantly employed for the SQ_150 PV module considering the TDM with diverse solar irradiance and temperatures, where significant closeness between the emulated and experimental P–V curves is evidently demonstrated.
Unterschiede in der Therapie entzündlich rheumatischer und
degenerativer Füße. Die Vorfußchirurgie
Authors: Hassel Kathryn 
Published: June 2022

ZusammenfassungDer Unterschied zwischen rheumatischen und degenerativen Veränderungen am
Fuß liegt in der fortschreitenden Destruktion der Gelenke bei
persistierender Synovialitis der rheumatoiden Arthritis (RA). Unter der heute
wirksameren immunsuppressiven Therapie und eines frühen und aggressiven
Beginns zeigen sich mildere Verlaufsformen. So können zunehmend auch
gelenkerhaltende Verfahren der Vorfußchirurgie Anwendung finden.
Entscheidend ist hier jedoch die Remission mit sicherer Krankheitskontrolle
für den gelenkerhaltenden Eingriff. Dennoch ist das Rezidiv- und
Fehlstellungsrisiko aufgrund wiederkehrender arthritischer Phasen höher.
Rheumaorthopädische Standardverfahren, wie die Arthrodese des
Großzehengrundgelenkes mit Resektion der Metatarsaleköpfchen
haben aber Ihren Stellenwert beim Vollbild des erosiven rheumatischen
Vorfußes nicht verloren. Ein standardisiertes Vorgehen fehlt. Umso
wichtiger ist es, mit jedem Patienten individuell die richtigen
Maßnahmen zu festzulegen.
Tendons and Tendon Sheaths of the Hand – An Update on MRI
Authors: Schmitt Rainer , Hesse Nina , Grunz Jan-Peter 
Published: June 2022

Background The tendons of the hand run in close proximity to each other and within retinacular tunnels adjacent to articular joints, while forming intersections in characteristic locations. The enclosing tendon sheaths are often sites of systemic or infectious inflammation.
Method This review article outlines the different entities of tendon and tendon sheath pathology and their manifestation in the hands. Diagnostic findings in tendon and tendon sheath disorders are illustrated using MRI imaging and discussed in context with the current literature.
Results and Conclusion Overuse may cause stenosis in the fibrous outer layer of the retinacula and the A1 annular ligaments as well as tendinosis. In contrast, proliferative tenosynovitis is a disease of the synovial inner layer of the tendon sheath with tendon infiltration and tendinitis. Pyogenic tenosynovitis favors the flexor compartments. Because of the narrow spaces in the hand, a high-resolution MRI technique must be used.

Published: June 2022

AbstractSNS-based ruthenium pincer catalysts were applied in a Guerbet condensation reaction of primary alcohols to give β-alkylated dimeric alcohols in good yields. The ability of these complexes to convert ethanol into butanol was also investigated. The work was then extended toward the C-alkylation of secondary alcohols with primary alcohols to give α-alkylated ketones. Several control experiments showed the involvement of borrowing hydrogen in the protocol.

Abstract
Background Over one-third of deaths recorded at health facilities in Zambia are brought in dead (BID) and the causes of death (CODs) are not fully analyzed. The use of automated verbal autopsy (VA) has reportedly determined the CODs of more BID cases than the death notification form issued by the hospital. However, the validity of automated VA is yet to be fully investigated.
Objectives To compare the CODs identified by automated VA with those by complete autopsy to examine the validity of a VA tool.
Methods The study site was the tertiary hospital in the capital city of Zambia. From September 2019 to January 2020, all BID cases aged 13 years and older brought to the hospital during the daytime on weekdays were enrolled in this study. External COD cases were excluded. The deceased's relatives were interviewed using the 2016 World Health Organization VA questionnaire. The data were analyzed using InterVA, an automated VA tool, to determine the CODs, which were compared with the results of complete autopsies.
Results A total of 63 cases were included. The CODs of 50 BID cases were determined by both InterVA and complete autopsies. The positive predictive value of InterVA was 22%. InterVA determined the CODs correctly in 100% cases of maternal CODs, 27.5% cases of noncommunicable disease CODs, and 5.3% cases of communicable disease CODs. Using the three broader disease groups, 56.0% cases were classified in the same groups by both methods.
Conclusion While the positive predictive value was low, more than half of the cases were categorized into the same broader categories. However, there are several limitations in this study, including small sample size. More research is required to investigate the factors leading to discrepancies between the CODs determined by both methods to optimize the use of automated VA in Zambia.

Objectives In the adult and pediatric critical care population, point-of-care ultrasound (POCUS) can aid in diagnosis, patient management, and procedural accuracy. For neonatal providers, training in ultrasound and the use of ultrasound for diagnosis and management is increasing, but use in the neonatal intensive care unit (NICU) is still uncommon compared with other critical care fields. Our objective was to describe the process of implementing a POCUS program in a large academic NICU and evaluate the role of ultrasound in neonatal care during early adaption of this program.
Study Design A POCUS program established in December 2018 included regular bedside scanning, educational sessions, and quality assurance, in collaboration with members of the cardiology, radiology, and pediatric critical care divisions. Core applications were determined, and protocols outlined guidelines for image acquisition. An online database included images and descriptive logs for each ultrasound.
Results A total of 508 bedside ultrasounds (76.8% diagnostic and 23.2% procedural) were performed by 23 providers from December 2018 to December 2020 in five core diagnostic applications: umbilical line visualization, cardiac, lung, abdomen (including bladder), and cranial as well as procedural applications. POCUS guided therapy and influenced clinical management in all applications: umbilical line assessment (26%), cardiac (33%), lung (14%), abdomen (53%), and cranial (43%). With regard to procedural ultrasound, 74% of ultrasound-guided arterial access and 89% of ultrasound-guided lumbar punctures were successful.
Conclusions Implementation of a POCUS program is feasible in a large academic NICU and can benefit from a team approach. Establishing a program in any NICU requires didactic opportunities, a defined scope of practice, and imaging review with quality assurance. Bedside clinician performed ultrasound findings can provide valuable information in the NICU and impact clinical management.

Published: June 2022

AbstractMaternal health is a major concern in Africa especially due to high level of maternal mortality in the region. A significant cause of high mortality is the unavailability of health facilities and preference for home-based delivery often carried out by unskilled health attendants. Reports reveal that 69% of young women in Nigeria opt for home-based delivery in Nigeria and some of these mothers lose their lives as a result of childbirth complications that are not properly attended to. This trend calls for urgent concern in the nation’s health system. Against this backdrop, this study examined the determinants of non-institutional delivery among women of reproductive age in Nigeria using the country’s National Demographic Health Survey [NDHS] (2018. Demographic health survey data. NPC and ICF, Abuja, Nigeria and Rockville. MD, USA) The data for this study include 12,567 of women of childbearing-age contained in the NDHS data. To analyse the data, the multilevel binary logistic regression was used to examine the determinants of non-institutional delivery among the women of childbearing-age. The results were presented using adjusted odds ratios (AOR) with 95% confidence interval. The result revealed that 56.8% of women preferred to have their children outside health institutions. The findings further revealed that educated women including urban dwellers, women with some level of formal education, high exposure to news media, high level of income and women with significant level of autonomy were less likely to deliver their babies outside health institutions. Based on the findings of the study, that there is the need to expand educational opportunities for Nigerian women, enhance and strengthen advocacy, and utilise focused group discussions, family outreach programmes and peer education to educate mothers on the benefits of using healthcare facilities during childbirth.
Feasibility of using melatonin content in pepper (

Published: June 2022

The presence of melatonin, a known animal hormone, has been confirmed in many evolutionary distant organisms, including higher plants. It is known that melatonin increases tolerance to stress factors as a wide spectrum antioxidant. Tolerant genotypes have generally higher melatonin content than sensitive ones, and exposure to stressful conditions is known to increase endogenous melatonin levels. However, endogenous melatonin levels in seeds have never been used to select genotypes tolerant to abiotic stresses. Thus, in this study, the existence of possible relationship between seed melatonin levels of 28 pepper (Capsicum annuum L.) genotypes and their germination and emergence performance under chilling conditions (15°C) was investigated. The results indicated that these parameters were much better for pepper genotypes with higher seed melatonin contents while those having less than 2 ng g−1 additionally exhibited elevated levels of MDA and H2O2 but lower antioxidant enzyme activities. Thus, a positive relationship between seed melatonin content and chilling stress tolerance has been shown, suggesting a possible use of endogenous melatonin levels as a criterion in selecting chilling stress tolerant varieties. To save considerable time, money and labour, it is recommended that genotypes with lower melatonin contents are excluded from breeding programmes that aim to develop new stress tolerant genotypes.

Published: June 2022

Abstract
Stretchable electrochromic devices (ECDs) were fabricated from electrospun PEDOT:PSS (poly(3, 4-ethylenedioxythiophene):polystyrene sulfonate) fibers. Stretchable and transparent electrodes with a sheet resistance of 1200 Ω sq−1 were prepared by depositing the conductive fibers on elastomeric substrates that were prepared from polydimethylsiloxane. The conductive substrates replaced the ITO coated glass electrodes that are typically used in ECDs. The functioning device was prepared from a flexible chitosan electrolytic gel and a 4, 7-bis(4-diphenylaminophenyl)−2, 1, 3-benzothiaziazole (TPA-BZT-TPA) electrochrome that were deposited on the streatchable transparent electrodes. The assembled device could be stretched to 150% its original length and bent to a curvature of 0.1. The device could be operated and switched between its yellow (off) and blue (on) states while being stretched and bent with a maximum contrast ΔT ≈ 30% at 805 nm and a coloration efficiency of 168 cm2 C−1. The stretchable device had an electrochromic contrast that was 30% greater than its counterpart that was prepared from conventional ITO-glass electrodes. The critical composition required for making devices truly stretchable was possible by evaluating the performance of five types of devices consisting of different layers.

Abstract
The electron and heat transports in solids are through the movement of carrier electrons and quantized lattice vibrations (phonons), which are sensitive to the lattice distortion and ionized impurities, and are essential aspects for the development of novel thermoelectric materials. In this study, we systematically investigated the modulations of electrical and thermal conductivities of BaTi1–x
Nb

O3 solid solution (BTNO, 0 ≤ x ≤ 1) epitaxial films. At room temperature, BaTiO3 belongs to tetragonal perovskite and exhibits electron conduction through doubly degenerated Ti 3d-t2g orbitals upon doping, while BaNbO3 belongs to cubic perovskite and exhibits metallic electron conduction through partially filled triply degenerate Nb 4d-t2g orbitals. By controlling the Ti/Nb ratio, we found a dual modulation effect on both the lattice structures and conduction band, which affects the electrical and thermal conductivities. Similar to the SrTi1–x
Nb
x
O3 solid solution (STNO, 0 ≤ x ≤ 1) system, a phase transition was detected at x ∼ 0.5, at which both the electron and heat transports exhibit abrupt changes. Unlike the transition in STNO, which was attributed to a polaronic phase transition, the transition in BTNO was due to contributions from both the lattice distortion and polaron effect. By controlling the lattice distortion, conduction band, and polaronic phase transitions, the electrical and thermal conductivity of BTNO epitaxial films are modulated within a much greater range than those of the STNO epitaxial films. Due to the double contribution of electron carriers and phonon to thermal conductivity (κ), the maximum κ modulation ratio of BTNO epitaxial films was ∼6.9. Our research provides an effective route to design electrical/thermal management materials.
Artificial atoms from cold bosons in one dimension

Published: June 2022

Abstract
We investigate the ground-state properties of weakly repulsive one-dimensional bosons in the presence of an attractive zero-range impurity potential. First, we derive mean-field solutions to the problem on a finite ring for the two asymptotic cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering state. Moreover, we derive the critical line that separates these regimes in the parameter space. In the thermodynamic limit, this critical line determines the maximum number of bosons that can be bound by the impurity potential, forming an artificial atom. Second, we validate the mean-field results using the flow equation approach and the multi-layer multi-configuration time-dependent Hartree method for atomic mixtures. While beyond-mean-field effects destroy long-range order in the Bose gas, the critical boson number is unaffected. Our findings are important for understanding such artificial atoms in low-density Bose gases with static and mobile impurities.

Abstract

Background
non-motor symptoms such as bladder dysfunction are common (80%) in people with Parkinson’s increasing the risk for falls with a negative impact on health-related costs and quality of life.
We undertook STARTUP to evaluate the clinical and cost-effectiveness of using an adhesive electrode to stimulate the transcutaneous tibial nerve stimulation (TTNS) to treat bladder dysfunction in people with Parkinson’s disease (PD).
Study design, materials and methods: STARTUP was a parallel two-arm, multi-centre, pragmatic, double-blind, randomised controlled trial. Each participant attended one clinic visit to complete consent, be randomised using a computer-generated system and to be shown how to use the device.
The trial had two co-primary outcome measures: International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and the International Prostate Symptom Score (IPSS). These were completed at baseline, 6 and 12 weeks. A bladder frequency chart and resource questionnaire were also completed.

Results
two hundred forty two participants were randomised. About 59% of participants were male, the mean age was 69 years and mean time since diagnosis was 6 years. Questionnaire return rate was between 79 and 90%.
There was a statistically significantly lower score in the active group at 6 weeks in the IPSS questionnaire (mean difference (Standard deviation, SD) 12.5 (6.5) vs 10.9 (5.5), effect size −1.49, 95% CI −2.72, −0.25). There was no statistically significant change in any other outcome.

Conclusion
TTNS was demonstrated to be safe with a high level of compliance. There was a significant change in one of the co-primary outcome measures at the end of the treatment period (i.e. 6 weeks), which could indicate a benefit. Further fully powered RCTs are required to determine effective treatments.
1043 FRAGILITY FRACTURE RISK ASSESSMENT IN THE OLDER PERSON’S RAPID ACCESS CLINIC (OPRAC): A QUALITY IMPROVEMENT PROJECT

Published: June 2022

Abstract

Background
One-in-two women and one-in-five men &gt;50 years are expected to have an osteoporotic fracture during their lifetime. However, despite this 1-in-5 women who have broken a bone, break 3 or more before being diagnosed, highlighting the importance of early diagnosis.
Aim NICE recommends a fragility fracture risk assessment in all women aged &gt;65 and men &gt;75 years. However, during our review of patients attending OPRAC, we found that only 3% of patients had an assessment done. Therefore, the primary aim of this project was to improve risk assessment of fragility fractures in this setting.

Method
We analysed the data for patients attending OPRAC between 23.09.20–23.10.20 and 01.05.21–15.06.21. We captured 35 and 51 patients respectively and sought to identify what proportion of the population had an accurate height, weight and fragility fracture assessment. We carried out our QIP using the PDSA cycle. Our interventions consisted of departmental teaching, posters and inclusion of fracture risk assessment in our induction handbook.

Results
The risk assessment went up from 3% to 33% post-intervention and documentation of height and weight went up from 74% to 98%. We retrospectively calculated the FRAX score for every single patient to assess whether the patients were receiving the appropriate treatment according to their risk score. What was consistent across both cycles was that if a patient had a risk assessment done, they were far more likely to have the correct treatment—89% and 82% in cycles 1 and 2 vs. 54% and 30% in those who didn’t have an assessment.

Conclusion
The above highlights what we already know about the importance of early diagnosis and treatment of osteoporosis. The interventions we have implemented have made a difference however further incorporation of fragility fracture assessments in clinical protocols is needed to bring about sustained change.
