Authors: Lerotholi Mpho , Bezuidenhout Adéle 
Published: May 2023

AbstractBackgroundThe global shortage of nurses, intensified by nurses migrating to richer countries, creates a health crisis in developing countries. This study investigates how strategic talent management practices can improve the work engagement of professional nurses in public hospitals in South Africa.MethodsA cross‐sectional, self‐administered survey was conducted among professional nurses employed in three large public hospitals in the Gauteng Province of South Africa. We measured: (1) management commitment, (2) talent review, (3) workforce planning, (4) staffing, (5) talent acquisition, (6) talent development, (7) talent commitment and (8) talent retention. The sub‐dimensions of work engagement that were measured included: (1) vigour, (2) absorption and (3) dedication. Descriptive and inferential (multiple regression) analyses were performed. The gap analysis calculated the difference between the current and desired status means talent management item.ResultsThe gap analysis revealed the biggest discrepancies between the value nurses attach to and the current status of management commitment and the talent review and staffing processes. Multiple regression analyses confirmed that current status‐rating talent acquisition impacts dedication and absorption combined (r = 0.112, p‐value = 0.012 < 0.05) and management commitment impacts absorption and vigour combined (r = 0.26, p‐value = 0.026 < 0.05). The importance‐rating revealed talent development and commitment combined influences dedication and absorption combined (r = 0.092, p‐value = 0.038 < 0.05), and talent review and planning impacts absorption and vigour combined (r = 0.115, p‐value = 0.010 < 0.05). Age and job status had a significant effect on absorption–vigour.ConclusionHospital managers can improve the engagement of nurses by demonstrating their commitment to talent development, offering a diverse variety of development opportunities and ensuring a pipeline of new nurses by improving the attractiveness of the profession. The study shows how strategic talent management practices can serve to improve work engagement in the healthcare sector.

AbstractSmart transmitters are increasingly being deployed in safety critical systems. Although the processing and diagnostic features provided by digital systems are advantageous, it introduces additional complexity in reliability modelling of systems. The conventional Fault Tree Analysis (FTA) method for system reliability analysis has its shortcomings in modelling digital systems, to incorporate its dynamic system interaction and failure modes in detail. This is because some of the failure modes may arise due to the dynamic interactions between the modules of the system. Dynamic Flowgraph Methodology (DFM) was identified as one of the optimistic approaches to handle these interactions. DFM approach combines multi‐valued logic modelling and analysis capabilities to handle systems consisting of components that have multiple degraded states and exhibit dynamic behaviour. However, only few DFM tools have been developed and some of them are not available in public domain. The DFM approach relies heavily on development and implementation of its decision tables. The logic information present within the decision tables can be meticulously implemented using Petri Nets. Also, there are plenty of free Petri Nets tools available online. Thus, the idea of DFM was used in this work to capture the dynamic interactions by developing decision tables. The decision tables were transformed into the Petri Net models to perform the analysis. The paper demonstrates the potential of the hybrid DFM – Petri Net approach for dynamic reliability analysis of smart transmitter.
An obstacle avoidance strategy for complex obstacles based on artificial potential field method
Authors: Zhang Wei , Xu Guojun , Song Yan , Wang Yagang 
Published: May 2023

AbstractWhen there are obstacles around the target point, the mobile robot cannot reach the target using the traditional artificial potential field (APF). Besides, the traditional APF is prone to local oscillation in complex terrain such as three‐point collinear or semiclosed obstacles. Aiming at solving the defects of traditional APF, a novel improved APF algorithm named back virtual obstacle setting strategy‐APF has been proposed in this paper. There are two main advantages of the proposed method. First, by redefining the gravitational function as a logarithmic function, the proposed method can make the mobile robot reach the target point when there are obstacles around the target. Second, the proposed method can avoid falling into local oscillation for both three‐point collinear and semiclosed obstacles. Compare with APF and other improved APF, the feasibility of the algorithm is proved through software simulation and practical application.

AbstractSilicon oxide (SiOx), inheriting the high‐capacity characteristic of silicon‐based materials but possessing superior cycling stability, is a promising anode material for next‐generation Li‐ion batteries. SiOx is typically applied in combination with graphite (Gr), but the limited cycling durability of the SiOx/Gr composites curtails large‐scale applications. In this work, this limited durability is demonstrated in part related to the presence of a bidirectional diffusion at the SiOx/Gr interface, which is driven by their intrinsic working potential differences and the concentration gradients. When Li on the Li‐rich surface of SiOx is captured by Gr, the SiOx surface shrinks, hindering further lithiation. The use of soft carbon (SC) instead of Gr can prevent such instability is further demonstrated. The higher working potential of SC avoids bidirectional diffusion and surface compression thus allowing further lithiation. In this scenario, the evolution of the Li concentration gradient in SiOx conforms to its spontaneous lithiation process, benefiting the electrochemical performance. These results highlight the focus on the working potential of carbon as a strategy for rational optimization of SiOx/C composites toward improved battery performance.

Abstract
Introduction and hypothesis
Symptoms of pelvic organ prolapse (POP) can affect quality of life and are reported to progress during the day, although this was never objectified. The aim of this study is to determine whether the pelvic anatomy changes during the day using upright magnetic resonance imaging (MRI), in POP patients and asymptomatic women.

Methods
In this prospective study 15 POP patients and 45 asymptomatic women were included. Upright MRI scans were obtained three times per day. The distances from the lowest points of the bladder and cervix to a standardized reference (pelvic inclination correction system) line were determined. A principal component analysis was performed on the levator plate (LP) shape. Statistical differences between time points and the groups were determined for the bladder, cervix, and LP shape.

Results
For all women a significant decrease in bladder and cervix height of −0.2 cm (p<0.001) was seen between morning/midday and afternoon scans. A significant difference in bladder descent during the day between POP patients and asymptomatic women was found (p=0.004). Individual differences in bladder position in the POP group of up to 2.2 cm between the morning and afternoon scan were reported. There was a significant difference in LP shape (p<0.001) between the groups but there were no significant changes during the day.

Conclusions
This study found no clinically relevant pelvic anatomy changes during the day. Still, on an individual level differences can be large, so repeating clinical examination at the end of the day can be recommended in patients when anamnesis and physical examination do not match.
A whole new world of healing: exploring medical hypnotherapy for pediatric patients
Authors: Bastek Vanessa , van Vliet Michel 
Published: May 2023

AbstractThis narrative review aims to unravel the potential of medical hypnotherapy for the treatment of children with a variety of diseases and symptoms. Going beyond its history and assumed neurophysiology, the chances of success for hypnotherapy will be outlined per pediatric speciality, accentuated by clinical research and experiences. Future implications and recommendations are given on extracting the positive effects of medical hypnotherapy for all pediatricians. Conclusion: Medical hypnotherapy is an effective treatment for children with specified conditions such as abdominal pain or headache. Studies suggest effectiveness for other pediatric disciplines, from the first line up to third line of care. In a time in which health is defined as 'a state of complete physical, mental and social well-being’, hypnotherapy stays an underrated treatment option for children. It is a unique mind–body treatment, which true potential still needs to be unraveled.

What is Known:• Mind–body health techniques become a more relevant and accepted part of treatment in pediatric patients.• Medical hypnotherapy is an effective treatment for children with specified conditions such as functional abdominal pain.

What is New:• Studies suggest the effectiveness of hypnotherapy in a high variety of pediatric symptoms and disease.• Hypnotherapy is a unique mind–body treatment which potential goes far beyond its current utilization.

Published: May 2023

AbstractEgypt is characterized by a wide variety of granitic rocks, making it one of the most essential ten countries producing ornamental stones worldwide. The main objective of this article is to study the effect of the chemical and mineralogical variations of the granitic rocks on their thermal expansion behaviors and physico-mechanical properties for use as dimension stones. The assessment of these rocks was performed using two main parameters: the first dealt with the petrographic investigation and chemical analysis for mineralogical and geochemical characterization. The second dealt with some essential physical and mechanical properties (e.g., water absorption, bulk density, and apparent porosity, and compressive strength), and thermal behavior in terms of linear thermal expansion coefficient. Based on the petrographic description, the samples were classified into five types: syenogranite, alkali-feldspar granite, albitized granite, granodiorite, and tonalite. The mineralogical characterization exhibited variable proportions of quartz and feldspars (plagioclase and alkali-feldspar), in addition to accessory minerals such as titanite, zircon, rutile, and iron oxide-based minerals. The thermal investigation showed insignificant changes in the thermal coefficient values and the thermal strain up to 100 °C as it did not exceed 0.049%, which indicates that they can be installed in places of high-temperature conditions. The physico-mechanical properties revealed that the water absorption ranged from 0.14 to 0.52%, the bulk density ranged from 2590.42 to 2748.23 kg/m3, and the compressive strength ranged from 314.17 to 628.75 kg/cm2. These results indicate that the studied granites could be acceptable for interior (indoor) and light-duty exterior purposes such as building cladding.
OCPP in the spotlight: threats and countermeasures for electric vehicle charging infrastructures 4.0

Published: May 2023

AbstractUndoubtedly, Industry 4.0 in the energy sector improves the conditions for automation, generation and distribution of energy, increasing the rate of electric vehicle manufacturing in recent years. As a result, more grid-connected charging infrastructures are being installed, whose charging stations (CSs) can follow standardized architectures, such as the one proposed by the open charge point protocol (OCPP). The most recent version of this protocol is v.2.0.1, which includes new security measures at device and communication level to cover those security issues identified in previous versions. Therefore, this paper analyzes OCPP-v2.0.1 to determine whether the new functions may still be susceptible to specific cyber and physical threats, and especially when CSs may be connected to microgrids. To formalize the study, we first adapted the well-known threat analysis methodology, STRIDE, to identify and classify threats in terms of control and energy, and subsequently we combine it with DREAD for risk assessment. The analyses indicate that, although OCPP-v2.0.1 has evolved, potential security risks still remain, requiring greater protection in the future.

AbstractRoot herbivores pose a major threat to agricultural crops. They are difficult to control and their damage often goes unnoticed until the larvae reach their most devastating late instar stages. Crop diversification can reduce pest pressure, generally without compromising yield. We studied how different diversified cropping systems affected the oviposition and abundance of the specialist cabbage root flyDelia radicum, the most important root herbivore inBrassicacrops. The cropping systems included a monoculture, pixel cropping, and four variations of strip cropping with varying intra- and interspecific crop diversity, fertilization and spatial configuration. Furthermore, we assessed whether there was a link betweenD. radicumand other macroinvertebrates associated with the same plants. Cabbage root fly oviposition was higher in strip cropping designs compared to the monoculture and was highest in the most diversified strip cropping design. Despite the large number of eggs, there were no consistent differences in the number of larvae and pupae between the cropping systems, indicative of high mortality ofD. radicumeggs and early instars especially in the strip cropping designs.D. radicumlarval and pupal abundance positively correlated with soil-dwelling predators and detritivores and negatively correlated with other belowground herbivores. We found no correlations between the presence of aboveground insect herbivores and the number ofD. radicumon the roots. Our findings indicate that root herbivore presence is determined by a complex interplay of many factors, spatial configuration of host plants, and other organisms residing near the roots.
An Alternative to the Born Rule: Spectral Quantization
Authors: Dvorak Marc 
Published: May 2023

AbstractWe show that there is a hidden freedom in quantum many-body theory associated with overcompleteness of the time evolution through the single-particle subspace of a many-body system. To fix the freedom, an additional constraint is necessary. We argue that the appropriate constraint on the time evolution through the subspace is to quantize the propagation of entangled pairs of particles, represented by the single-particle spectral function, instead of individual particles. This solution method creates a surface that indicates the multiplicity of every solution to the inverse problem defined by matching the freedom to the constraint. Upon measurement, the system collapses nonlocally onto a single quantized solution. In addition to a combinatoric multiplicity, each solution acquires a multiplicity due to its stability when subject to a small variation in the microscopic degrees of freedom. Numerical calculations for a two-level system show that our theory improves upon standard theory in the description of non-quasiparticle spectral features. Our reinterpretation of quantum many-body theory is not based on the Born rule and offers a more faithful representation of experiments than current theory by modeling individual, quantized events with an explicit collapse model.

AbstractTransmission-based muography (TM) is an innovative imaging technique based on the measurement and analysis of the cosmic ray muons flux attenuation within the target under investigation. This technique allows imaging inner-body density differences and has successfully been applied in a wide range of research fields: geology, archaeology, engineering geology and civil engineering. The aim of this study is to show the reliability of TM as an innovative, noninvasive geophysical method for ore body prospecting and other mining related studies. The measurements were carried out at the Temperino mine in the San Silvestro Archaeological and Mining Park (Campiglia Marittima, Italy), where several magmatic and metasomatic geological units are embodied. Among them, a Cu–Fe–Zn–Pb(–Ag) sulfide skarn complex primarily composed by hedenbergite and ilvaite minerals. Using the acquired muon imaging data obtained with the MIMA (Muon Imaging for Mining and Archaeology) detector prototype (cubic detector of 0.5 × 0.5 × 0.5 m3), the presence of a high-density vein inside the skarn body within the rock volume above the muon detector was identified, localized and interpreted. Applying a back-projection algorithm to the obtained 2D transmission map made it possible to estimate and visualize as point cloud data, in a 2D or 3D environment, the identified high-density body and its relative distance from the detector. The results of this study highlight the potential of muography as a support tool to other geophysical methods in the field of mining exploration.
Nonprofits for Cohesive Cities: Neighborhood Characteristics, Organizational Practices, and their Effects on Social and Systemic Integration

Published: May 2023

AbstractNonprofit organizations (NPOs) contribute to vital neighborhoods by building communities of citizens and acting as intermediaries between citizens and organizations. We investigate how NPOs’ engagement in social and systemic integration is shaped by neighborhood characteristics, and how it relates to the organizational practices of managerialism and organizational democracy. We combine survey data with administrative data from a representative sample of NPOs in a major European city. To measure the effect of neighborhood on organizational integration, we separated the city into 7,840 grid cells characterized by population, per capita income, share of immigrant population, and density of organizations. Findings indicate that managerialism positively relates with systemic integration, as organizational democracy relates with social integration. Neighborhood characteristics, however, are not related with NPOs’ engagement in integration. Our findings contribute to research on urban social cohesion by illuminating the interplay between NPOs’ organizing practices, local neighborhoods, and contributions to both forms of integration.

Abstract
Purpose
To assess the diagnostic performance of Whole Body (WB)-MRI in comparison with 18F-Fluorodeoxyglucose-PET/CT (18F-FDG-PET/CT) in lymphoma staging and to assess whether quantitative metabolic parameters from 18F-FDG-PET/CT and Apparent Diffusion Coefficient (ADC) values are related.

Materials and methods
We prospectively enrolled patients with a histologically proven primary nodal lymphoma to undergo 18F-FDG-PET/CT and WB-MRI, both performed within 15 days one from the other, either before starting treatment (baseline) or during treatment (interim). Positive and negative predictive values of WB-MRI for the identification of nodal and extra-nodal disease were measured. The agreement between WB-MRI and 18F-FDG-PET/CT for the identification of lesions and staging was assessed through Cohen's coefficient k and observed agreement. Quantitative parameters of nodal lesions derived from 18F-FDG-PET/CT and WB-MRI (ADC) were measured and the Pearson or Spearman correlation coefficient was used to assess the correlation between them. The specified level of significance was p ≤ 0.05.

Results
Among the 91 identified patients, 8 refused to participate and 22 met exclusion criteria, thus images from 61 patients (37 men, mean age 30.7 years) were evaluated. The agreement between 18F-FDG-PET/CT and WB-MRI for the identification of nodal and extra-nodal lesions was 0.95 (95% CI 0.92 to 0.98) and 1.00 (95% CI NA), respectively; for staging it was 1.00 (95% CI NA). A strong negative correlation was found between ADCmean and SUVmean of nodal lesions in patients evaluated at baseline (Spearman coefficient rs = − 0.61, p = 0.001).

Conclusion
WB-MRI has a good diagnostic performance for staging of patients with lymphoma in comparison with 18F-FDG-PET/CT and is a promising technique for the quantitative assessment of disease burden in these patients.
