Published: May 2024

AbstractRock bolts play a critical role in ground support in mining, tunneling and construction. Being able to obtain timely information on rock bolt load condition and deformation could help immensely in safeguarding workers’ safety, optimization of ground support system, and ensuring stability and longevity of underground structures. The objective of this work was to develop a practical ultrasonic rock bolt sensing technology for monitoring axial load and deformation of a full-bodied rock bolt in both elastic and plastic deformation regimes. To this end, empirical mathematical models involving simultaneous use of times of flight of longitudinal and shear ultrasonic waves propagating along the axial direction of the rock bolt were developed, sensors were designed and fabricated, and laboratory studies were conducted. The results showed that the technology was able to measure load change, provide early detection of yield, and measure both plastic and total elongations of the rock bolt undergoing a pull test. Additionally, sectional load and elongation information could be obtained by applying the technology to rock bolts divided into sections by drilled holes along their shanks, therefore, providing the capability to assess the condition of grouted bolts at different depths within a rock mass. This work has laid the groundwork for the deployment of the technology in the field.
Synthesis, characterization and stability of phosphonium phenolate zwitterions derived from a (diphenylphosphino)phenol derivative and oxiranes

Published: May 2024

AbstractPhosphonium phenolate zwitterions have been synthesized from 2,4-di-tert-butyl-6-(diphenylphosphino)phenol and five different oxirane derivatives. The reaction does not proceed at a detectable rate when the two reactants are combined in dichloromethane at room temperature. Despite the substantial ring strain, the reaction proceeds only with the addition of methanol, which acts as a hydrogen transfer shuttle, allowing a slow conversion to the desired zwitterions. The compounds have been fully characterized and single crystal X-ray crystallography has been performed on the methyloxirane and the phenyl glycidyl ether-derived zwitterion. The phosphonium phenolate units exhibit an ylidic bonding situation as evidenced by spectroscopic and crystallographic analysis. Glycidyl ethers were found to react faster than alkyl and aryloxiranes. Decomposition studies of the zwitterions showed high thermal stability in solution under ambient conditions. Under forced conditions (150 °C, 6 h), decomposition to the corresponding phosphine oxide and secondary aliphatic alcohols, the formally hydrogenated oxirane derivative, was observed.

A novel technique for thulium laser enucleation of the prostate: anterior releasing with ThuLEP (ARTh technique)
Authors: Öztürk Hakan 
Published: May 2024

Abstract
Thulium laser enucleation of the prostate (ThuLEP) is a highly effective approach to the treatment of benign prostatic hyperplasia. We present here a description of the “ARTh Technique” and the benefits it offers in terms of improved visualization, short operation times, and easy recognition of the dissection plane, describing specifically the anterior release (AR) technique using ThuLEP(Th). Included in this retrospective study were 32 consecutive patients operated on between January 2022-November 2022. Parameters were measured before and after the procedure: the International Prostate Symptom Score(IPSS), maximum flow rate(Qmax), post-void residual urine(PVR) prostate-specific antigen(PSA), prostate volume, operation-time, morcellation-time, catheterization-time and presence of transient urinary incontinence, and compared. The median age of patients undergoing enucleation of the prostate using the ARTh technique was 64 years (range: 44–83). The median prostate volume of the patients was 83.5 ml(50–128 ml), preoperative-IPSS was 24.8(15–33), postoperative-IPSS was 7(5–11), preoperative-Qmax was 8.1 ml/Sects. (5–11.5 ml/sec), postoperative-Qmax was 26.9 ml/Sect. (20.8–34 ml/sec), preoperative-PVR was 145 ml(75–258 ml), postoperative-PVR was 36.2 ml(0–66 ml), total operation time was 51.4 min(28–82 min), enucleation time was 36.9 min(19–51 min) and morcellation time was 15.3 min(8–27 min). The ARTh technique is a safe procedure that allows the surgeon to easily recognize and adhere to the defined dissection plane, thus decreasing operation times, significantly reducing the rate of postoperative transient urinary incontinence (TUI).
Understanding what factors affect firefighter use of site-specific risk information
Authors: Waring Sara , Massey Georgia , Kalra Jeotpreen 
Published: May 2024

AbstractFire services have a responsibility to record information regarding known hazards for sites posing unique and substantial risks. Such information is important, both for informing service planning, and for supporting the development of situational awareness and decision-making during emergency response. However, public inquiries and service inspections have raised concerns regarding the effectiveness of systems in place for recording, monitoring, and using site-specific risk information (SSRI). In contrast, a lack of research focus has been directed toward the use of SSRI, limiting the evidence base available for understanding the causes of these difficulties and how they may be addressed. The following study seeks to contribute to developing knowledge by examines what factors affect the use of SSRI across organisational levels and why. Interviews were conducted with 23 firefighters from operational and tactical roles in one region of the UK. Thematic analysis highlighted six key themes: (i) Differences in the use of SSRI across organisational levels, (ii) System accessibility, (iii) Content, (iv) Structure, (v) Quality, and (vi) Training. Findings indicate that SSRI use is affected by the relevance, structure, and quality of information, which are influenced by workload, training, guidance, and system accessibility. During emergency response, information requirements, time and cognitive capacity differ across organisational levels, influencing the extent to which barriers affect ability to use SSRI. The implications of findings are discussed in relation to informing future areas of applied cognition research, and fire sector decisions regarding the gathering and storage of SSRI.
Is there a link between health care utilisation and subjective well-being? An exploratory study among older Danes
Authors: Aaskoven Maiken Skovrider , Kjær Trine , Gyrd-Hansen Dorte 
Published: May 2024

Abstract
While extensive research has explored the influence of traditional factors such as socioeconomic position on health care utilisation, the independent role of an individual’s well-being in their health care seeking behaviour remains largely uncharted territory. In this study, we delve into the role of subjective well-being (SWB) in health care utilisation. We use a unique link between survey data from a representative group of Danish citizens aged 50-80 and administrative register data containing information on health care utilisation and sociodemographics. We explore whether SWB is a predictor of health care utilisation (general practice services) over and above health (as measured by health-related quality of life (HRQoL)). We find that the association between SWB and number of services provided in general practice differs across levels of HRQoL. Among those with lower HRQoL, we find a positive association between health care utilisation and SWB. Results hold true even when controlling for previous health care utilisation, suggesting that the mechanism is not driven by reverse causality. Our findings suggest that, in particular for vulnerable individuals in poor health and with poor SWB, the propensity to seek care is inappropriately low, and there is a need for more proactive supply-driven health care.
An empirical analysis of factors determining changes in physical exercise during the COVID-19 pandemic
Authors: Pulgar Susana , Mazas Cristina , Kaviani Sepideh , Butts-Wilmsmeyer Carolyn , Fernandez-del-Valle Maria 
Published: May 2024

Abstract
Aim
The main objective of the study was to report the changes that have taken place in the practice of physical exercise during confinement and to examine the factors that favor or detract from it.

Material and methods
To determine the objective, a survey was carried out in the United States during the pandemic and a sample of 511 participants was obtained. A binary logit model was used to process the data, as well as several independence tests.

Results
The main result of this study is the increase in the practice of physical activity of the individuals surveyed during the pandemic. Some of the elements that most influenced this increase were annual family income, education level, and eating habits, but these results are subject to change depending on the respondent’s body mass index. On the other hand, the results also show changes in physical exercise habits during the pandemic, especially in the time of the week when it is performed, and these changes are highly correlated with the use of electronic devices, hours of sleep, and physical condition of the respondents before the pandemic.

Conclusion
Determining the different factors that affect the practice of physical exercise during pandemic periods seems to be important to determine in which populations it is more important to act or what resources are necessary when implementing physical exercise programs in specific situations such as pandemics.

AbstractMultifunctional cellulosic fibers are in high demand for use in a variety of applications. Functional cellulosic fibers obtained through green and sustainable approaches are getting special attention because of the need to limit the environmental impact of hazardous chemicals. Herein, a novel facile, efficient, and eco-friendly approach for multifunctional viscose fibers@Ag NPs (VF-Ag) was designed by a rapid, facile, and one-pot biosynthesis green route using guava leaf extract as a reducing and stabilizing agent. UV–Vis, TEM, SEM, EDX, FTIR, and XPS were used to analyze the formation of silver nanoparticles and their subsequent deposition on the surface of viscose fibers. The silver nanoparticles immobilized on the surface of viscose fibers endowed a yellow/brownish color to the fibers as well as improving the dyeing with reactive dye. The VF-Ag samples have multifunctional properties like protective activities against UV radiation and microorganisms, antioxidant activity, and sensor ability toward Hg2+. The results demonstrated that the UPF values of VF-Ag samples ranged from 280 to 355 compared to 103 for VF. The antioxidant activities of VF-Ag ranged from 79 to 85% compared to 9% for VF. VF-Ag samples exhibited excellent antimicrobial activities against Gram-positive and Gram-negative bacteria, very good activities against yeast, and low activities against fungus.VF and VF-Ag were dyed using reactive dye (CI-reactive blue-19) at two color intensities (2.5, and 5%). The results show that the color of VF turned blue, while the color of VF-Ag turned greenish. The color strength of VF-Ag significantly increased with increasing silver content. Furthermore, VF-Ag showed high sensitivity to naked-eye colorimetric sensing for the detection of Hg2+. In straightforward, this innovative approach provides an easy, quick, and low-cost that will open the door for a range of versatile applications for modified viscose fibers in the fields of medical and analytical applications.

Published: May 2024

AbstractAdolescent depression is associated with unhelpful emotional mental imagery. Here, we investigated whether vividness of negative and positive prospective mental imagery predict negative affect and anhedonia in adolescents. 111 people from Israel completed measures of prospective mental imagery, negative affect, and anhedonia at two time-points approximately three months apart. Using three cross-lagged panel models, we showed once ‘concurrent’ (across-variable, within-time) and ‘stability’ paths (across-time, within-variable) were estimated, there were no significant cross-lag paths between: i) T1 prospective negative mental imagery and T8 negative affect (i.e. increased vividness of negative future imagery at Time 1 did not predict increased negative affect at Time 8); ii) T1 prospective positive mental imagery and T8 negative affect (i.e. reduced vividness of positive future imagery at Time 1 did not predict increased negative affect at Time 8); and iii) T1 prospective positive mental imagery and T8 anhedonia (i.e. reduced vividness of positive future imagery at Time 1 did not predict increased anhedonia at Time 8). Given high levels of attrition, future research should aim to explore these associations in a larger, more diverse population, as such data could inform on whether modifying earlier prospective mental imagery may influence later time/context-specific effects of prospective mental imagery on negative affect and anhedonia.
Monitoring the Dynamic Networks of Stock Returns with an Application to the Swedish Stock Market
Authors: Touli Elena Farahbakhsh , Nguyen Hoang , Bodnar Olha 
Published: May 2024

AbstractIn this paper, two approaches for measuring the distance between stock returns and the network connectedness are presented that are based on the Pearson correlation coefficient dissimilarity and the generalized variance decomposition dissimilarity. Using these two procedures, the center of the network is determined. Also, hierarchical clustering methods are used to divide the dense networks into sparse trees, which provide us with information about how the companies of a financial market are related to each other. We implement the derived theoretical results to study the dynamic connectedness between the companies in the Swedish capital market by considering 28 companies included in the determination of the market index OMX30. The network structure of the market is constructed using different methods to determine the distance between the companies. We use hierarchical clustering methods to find the relation among the companies in each window. Next, we obtain a one-dimensional time series of the distances between the clustering trees that reflect the changes in the relationship between the companies in the market over time. The method from statistical process control, namely the Shewhart control chart, is applied to those time series to detect abnormal changes in the financial market.
Eliminating the ‘Impossible’: Recent Progress on Local Measurement Theory for Quantum Field Theory
Authors: Papageorgiou Maria , Fraser Doreen 
Published: May 2024

AbstractArguments by Sorkin (Impossible measurements on quantum fields. In: Directions in general relativity: proceedings of the 1993 International Symposium, Maryland, vol 2, pp 293–305, 1993) and Borsten et al. (Phys Rev D 104(2), 2021. https://doi.org/10.1103/PhysRevD.104.025012) establish that a natural extension of quantum measurement theory from non-relativistic quantum mechanics to relativistic quantum theory leads to the unacceptable consequence that expectation values in one region depend on which unitary operation is performed in a spacelike separated region. Sorkin [1] labels such scenarios ‘impossible measurements’. We explicitly present these arguments as a no-go result with the logical form of a reductio argument and investigate the consequences for measurement in quantum field theory (QFT). Sorkin-type impossible measurement scenarios clearly illustrate the moral that Microcausality is not by itself sufficient to rule out superluminal signalling in relativistic quantum theories that use Lüders’ rule. We review three different approaches to formulating an account of measurement for QFT and analyze their responses to the ‘impossible measurements’ problem. Two of the approaches are: a measurement theory based on detector models proposed in Polo-Gómez et al. (Phys Rev D, 2022. https://doi.org/10.1103/physrevd.105.065003) and a measurement framework for algebraic QFT proposed in Fewster and Verch (Commun Math Phys 378(2):851–889, 2020). Of particular interest for foundations of QFT is that they share common features that may hold general morals about how to represent measurement in QFT. These morals are about the role that dynamics plays in eliminating ‘impossible measurements’, the abandonment of the operational interpretation of local algebras $${\mathcal {A}}(O)$$

as representing possible operations carried out in region O, and the interpretation of state update rules. Finally, we examine the form that the ‘impossible measurements’ problem takes in histories-based approaches and we discuss the remaining challenges.
Aging in Indigenous Communities: Perspective from Two Ancestral Communities in the Colombian Andean–Amazon Region
Authors: García Hernán D. , García Wilson A. , Curcio Carmen L. 
Published: May 2024

AbstractThe phenomenon of world aging is not foreign to indigenous communities. In the last few years, research about these communities around the world has increased, but aging in indigenous towns still has not been studied widely. The purpose of this research is to interpret the meaning of old age in two indigenous communities from the Colombian Andean–Amazon region (the Inga and Kamëntsa) to reinforce the relevance of the local sociocultural context within the configuration of the meaning of old age and to emphasize the importance of considering particular regional characteristics for the design of policies and interventions aiming to recognize and integrate indigenous populations. This is a qualitative study with an interactionism–symbolism approach. In total, six indigenous people older than 60 years from two ancestral communities from the Colombian Andean–Amazon region participated in the in-depth interviews. Data analysis was carried out in three moments: discovery, coding, and relativization of the information. The results show that old age means wisdom, “I am wise,” which is supported in the cosmology and the trajectory of life, reinforces the identity and autonomy, and allows them to be agents in the dynamics of their communities from the “I do,” in other words, their roles as builders of the family–society and as guards of ancestral knowledge. The loss of this knowledge and the elements that it is composed of uproot them and put them at risk of disappearing as individuals and as a collective. In conclusion, the meaning of old age in these communities is not centered on a determinate age; you are not old, you are wise, and as such, they play a central role in their communities. Moreover, wisdom is built in parallel with their cosmology and assigns them the task of safekeeping ancestral knowledge. In order to do this, they use oral tradition as a tool, words that are born in their territories, travel in a nonlinear timeline, and get strengthened by the community while also protecting it and building it. Knowing what aging means for Indigenous communities can facilitate to the development of policies and initiatives and to provide culturally appropriate and effective programs.
They must live somewhere! The geographical dimension of residualized social rented housing in urban Norway
Authors: Brattbakk Ingar , Sørvoll Jardar 
Published: May 2024

AbstractThe residualization of public rented housing is a prevalent phenomenon throughout Europe, and strongly present in the small and strongly means-tested social housing sector in Norway. In this article, we discuss the contested geographical dimension of residualization. Scientific studies of the geographical and locational aspects of social housing are scare in Norway and modest internationally. Based on qualitative interviews with representatives of social housing administrators in the fifteen largest urban municipalities in Norway, this paper contributes to the literature by exploring how these social housing bureaucrats perceive, reflect on, and respond to, questions related to the spatial localization of residual social housing. Does it matter where social housing is located? What are the consequences of the geography of social housing for tenants, their neighbours, and the wider socio-spatial development of cities? These are questions pondered in the interviews. In our qualitative analysis, we identify three broad themes. First, the theme of the internal social milieu – inclusive communities versus neighbour complaints and conflicts in the public housing projects. Second, the theme of neighbourhood effects; how concentrated poverty is influencing the local community in general and the upbringing of children in particular. Third, the theme of response from external neighbours and communities, in the form of either predominantly exclusive strategies (NIMBYism – Not in My Backyard), but also less prevalent inclusive strategies like (PHIMBYism – Public Housing In My Backyard).
Application of Dual-target Computed Tomography for Material Decomposition of Low-Z Materials
Authors: Mikuláček Pavel , Zemek Marek , Štarha Pavel , Zikmund Tomáš , Kaiser Jozef 
Published: May 2024

AbstractThe extension of conventional computed tomography known as spectral computed tomography involves utilizing the variations in X-ray attenuation, driven by spectral and material dependencies. This technique enables the virtual decomposition of scanned objects, revealing their elemental constituents. The resultant images provide quantitative information, such as material concentration within the scanned volume. Enhancements in results are achievable through methods that capitalize on the strong correlation among decomposed images, effectively minimizing noise and artifacts. The Rigaku nano3DX submicron tomograph uses a dual-target source, which allows the generation of two distinct X-ray spectra through different target materials. This configuration holds promise for high-resolution applications in spectral tomography, particularly for low-Z materials, where it offers high contrast in the acquired images. The potential of this setup in the context of spectral computed tomography is explored in this contribution, delving into its applications for materials characterized by low atomic numbers.
