Published: October 2023

AbstractMorpholine−borane (MB) is a promising hydrogen storage material and developing effective catalysts for the catalytic hydrolysis reaction of MB has become a fascinating topic in catalysis. Here, we report the preparation of Al2O3‐supported Pd nanoparticles (Pd/Al2O3) by an impregnation‐reduction method and their utilization as catalysts in the catalytic hydrolysis reaction of MB for hydrogen (H2) production. These Pd/Al2O3 are characterized by a combination of several advanced analytical techniques. Pd/Al2O3 catalysts with a mean diameter of 3.12±0.35 nm provide H2 production with a turnover frequency (TOF) value of 495.3 mol(H2) ⋅ molPd−1 ⋅ h−1 in the hydrolysis of MB in complete conversion at 298 K. Additionally, the activation energy (Ea#), activation enthalpy (ΔH#), and activation entropy (ΔS#) values of Pd/Al2O3 catalysts in the hydrolysis reaction of MB are calculated as 30.36 kJ ⋅ mol−1, 28.42 kJ ⋅ mol−1, and −158.52 J ⋅ mol−1 ⋅ K−1, respectively, from Arrhenius and Eyring‐Polanyi equations.
Physical Phenomena Governing Mineral Morphogenesis in Molluscan Nacre

Published: September 2023

AbstractMollusks, as well as many other living organisms, have the ability to shape mineral crystals into unconventional morphologies and to assemble them into complex functional mineral–organic structures, an observation that inspired tremendous research efforts in scientific and technological domains. Despite these, a biochemical toolkit that accounts for the formation of the vast variety of the observed mineral morphologies cannot be identified yet. Herein, phase‐field modeling of molluscan nacre formation, an intensively studied biomineralization process, is used to identify key physical parameters that govern mineral morphogenesis. Manipulating such parameters, various nacre properties ranging from the morphology of a single mineral building block to that of the entire nacreous assembly are reproduced. The results support the hypothesis that the control over mineral morphogenesis in mineralized tissues happens via regulating the physico‐chemical environment, in which biomineralization occurs: the organic content manipulates the geometric and thermodynamic boundary conditions, which in turn, determine the process of growth and the form of the biomineral phase. The approach developed here has the potential of providing explicit guidelines for the morphogenetic control of synthetically formed composite materials.
Sterile neutrinos from dark matter: a ν nightmare?
Authors: Morrison Logan , Profumo Stefano , Shakya Bibhushan 
Published: September 2023

Abstract
We provide a comprehensive study of observable spectra from dark matter pair-annihilation or decay into sterile (right-handed) neutrinos. This occurs, for instance, in neutrino portal dark matter models, where a sterile neutrino acts as the portal between dark matter and the Standard Model sector. The subsequent decays of right-handed neutrinos produce detectable Standard Model particles, notably photons, positrons, and neutrinos. We study the phenomenology of models where the right-handed neutrino masses are below the GeV scale, as well as models where they are at, or significantly heavier than, the TeV scale. In both instances, and for different reasons, the standard tools, including Monte Carlo simulations, are both inadequate and inaccurate. We present the complete framework to compute the relevant branching ratios for right-handed neutrino decays and the spectra of secondary photons, positrons, and neutrinos for a broad range of dark matter and right-handed neutrino masses. We discuss the general features of such signals, and compare the spectra to standard signals from dark matter annihilation/decay into bottom quarks. Additionally, we provide open source code (The code is available at https://github.com/LoganAMorrison/blackthorn) that can be used to compute such spectra.

Published: October 2023

Abstract
Background
The removal of ureteral stent can be performed with disposable or reusable flexible cystoscopes, but limited comparative data are available on functionality, risk of infections, and costs.

Methods
We performed a multicentric, prospective, observational study on patients undergoing in-office ureteral stent removal with Isiris-α® or a reusable Storz™ flexible cystoscope. Study endpoints were the functionality and effectiveness of the devices, the rate of postoperative bacteriuria and UTIs, and the costs of the procedure.

Results
A total of 135 patients were included, 80 (59.2%) treated with reusable cystoscopes and 55 (40.8%) with Isiris-α®. No significant baseline differences between groups were detected. Isiris-α® outperformed the reusable device in terms of quality of vision (p 0.001), manoeuvrability (p 0.001), grasper functionality (p < 0.001), and quality of the procedure (p 0.01). Mean procedure time was shorter with Isiris-α® (p < 0.001) due to a shorter instrument preparation time (p < 0.001). No differences were found in terms of perceived patient pain (p 0.34), nor postoperative bacteriuria or symptomatic UTIs. According to our cost analysis, the in-office procedure performed with Isiris-α® was more expensive (+ 137.8€) but was independent from instrument turnover or disinfection. Among limitations of study we acknowledge the lack of randomization, the use of antibiotic prophylaxis in several patients, and the high rate of missing preoperative urine cultures.

Conclusions
Isiris-α® outperforms reusable cystoscopes for in-office ureteral stent removal in terms of total operative time and quality of the procedure, at the cost of being more expensive. No significant differences in postoperative bacteriuria or symptomatic UTIs were found.

Published: October 2023

AbstractHazardous hydrological events cause soil erosion and it is essential to anticipate the potential environmental impacts of prevailing erosion processes that occur at different time-scales. Here, we present the modelling of net soil erosion rates for the Bradano River Basin (southern Italy), based on rainfall erosivity, surface overland flow and transport sub-models. A semi-empirical framework was developed, upscaling point rainfall values based on the Foster-Thornes approach in order to give an insight into monthly and annual soil losses over the period 1950–1958 and 1961 (calibration) and over a longer time-frame (1950–2020: reconstruction). In the 2765-km2 study area, ~ 68% of the sediment mobilized within the basin reached the basin outlet (mean value for 1950–2020: ~ 366 Mg km−2 yr−1). A moderate declining trend in net erosion rates was observed after the 1980s, concurrent with the contraction of cropland in favour of natural vegetation and river channelization. Our results suggest that the parsimonious principle used here seems sufficiently robust to be suitable for applications in other Mediterranean landscapes.

Published: September 2023

AbstractThe rapid growth in the widespread acceptance and usage of the Internet and the ease of creating online communities have brought advantages in terms of swift access to information alongside ethical problems interrelated with the dark side of the workings of these communities. Relevant research approaching ethics and the dark side of online communities has received widespread publication in a diverse set of journals with a wide variety of objectives and readers that has left its academic contribution broadly fragmented. To help shrink this gap in the literature, this study, through undertaking a systematic review, seeks to map the research on ethics and the dark side of online communities to grasp where the literature has come from and where it is going and, consequently, provide opportunities for future research. This study applied a bibliometric approach based on analysis of the bibliographic coupling with the manual coding of documents to examine the literature on the ethics and the dark side of online communities to set out a holistic framework of its different facets. The content and the thematic analysis of 53 studies identified four thematic groups: quality of the information in online communities, virtual identities, safety in online communities, and the content of online communities. The findings of this study also highlight the various shortcomings in the literature on the ethics and dark side of online communities and lead to some research questions that justify future academic research.
Hidden Markov models for longitudinal rating data with dynamic response styles
Authors: Colombi Roberto , Giordano Sabrina , Kateri Maria 
Published: September 2023

AbstractThis work deals with the analysis of longitudinal ordinal responses. The novelty of the proposed approach is in modeling simultaneously the temporal dynamics of a latent trait of interest, measured via the observed ordinal responses, and the answering behaviors influenced by response styles, through hidden Markov models (HMMs) with two latent components. This approach enables the modeling of (i) the substantive latent trait, controlling for response styles; (ii) the change over time of latent trait and answering behavior, allowing also dependence on individual characteristics. For the proposed HMMs, estimation procedures, methods for standard errors calculation, measures of goodness of fit and classification, and full-conditional residuals are discussed. The proposed model is fitted to ordinal longitudinal data from the Survey on Household Income and Wealth (Bank of Italy) to give insights on the evolution of households financial capability.

Published: September 2023

Abstract
Purpose
In patients with neuroendocrine tumors (NETs) and liver metastases, increased gamma-glutamyltransferase (GGT) is commonly assumed as an indicator for progressive disease. To date, however, empirical data are lacking. This study aimed to investigate associations between GGT and liver tumor burden. In longitudinal analyses, associations of GGT and radiographic responses of liver metastases under therapy were investigated.

Methods
The cross-sectional sample consisted of 104 patients who were treated at the University Medical Center Hamburg-Eppendorf from 2008 to 2021 (mean age 62.3 ± 12.6 years, 58.7% male). GGT and liver imaging were identified in a time range of 3 months. Radiologic reassessments were performed to estimate liver tumor burden. In a separate longitudinal sample (n = 15), the course of GGT levels under chemotherapy was analyzed. Data were retrospectively analyzed with a univariate ANOVA, linear regression analyses, and Wilcoxon tests.

Results
Of 104 cross-sectionally analyzed patients, 54 (51.9%) showed a GGT elevation. GGT levels and liver tumor burden were positively correlated (p < 0.001), independently from age, gender, primary tumor location, grading, and cholestasis. Notably, GGT increase was associated with a liver tumor burden of >50%. In the longitudinal sample, 10 of 11 patients with progressive disease showed increasing GGT, whereas 4 of 4 patients with regressive disease showed declining GGT.

Conclusion
Our findings indicate that GGT is associated with liver tumor burden. Over the course of therapy, GGT appears to change in line with radiographic responses. Further longitudinal studies with larger sample sizes are required to define GGT as a reliable marker for tumor response.
Experimental study on dynamic response of rock tunnel subjected to train moving load

Published: October 2023

AbstractThe tunnels might be suffered from damage and destruction under the dynamic loads generated by trains moving on the upper railways, which can in turn threaten the safety of the railways. Understanding the dynamic response of tunnel under the train moving load is of significance for maintaining the operation safety of both the tunnel and upper railway. However, there is currently a lack of relevant research on this topic, especially regarding model experiments. To address this gap, this paper conducts physical model experiments on the train-rail-bridge-shaking table test system to investigate the dynamic response of tunnels subjected to train moving load. The experiment results revealed that except for the average peak particle velocity (PPA) at tunnel vault, the average PPAs at other locations and the vibration dominant frequency (f0) at all locations increase as the train moving speed (vtr) increases. With the exception of some special cases, the average PPAs on tunnel spandrels are generally less than that on the tunnel vault and greater than that on the tunnel invert. When the vtr exceeds 7.03 m/s, except for the average PPA at tunnel invert, the average PPAs on the tunnel wall are generally larger than those inside the surrounding rock mass. As vtr increases, the average f0 on tunnel wall changes more obviously compared to average f0 inside the surrounding rock mass. When the vtr exceeds 10.54 m/s, the average f0 on tunnel wall are noticeably larger than those inside the surrounding rock mass. The high coefficients of determination obtained from the nonlinear regression analysis indicates a power relationship between the average PPA and vtr, while the average f0 shows an exponential association with vtr. The research findings hold great importance in ensuring the safe operation of tunnels and railways.

Published: September 2023

Abstract
Objectives
Genomic advancements affect people with disabilities. This paper presents the findings of a scoping literature review on the ethical, legal, and social implications (ELSI) of genomic technologies for people with disability. The human rights implications of the ELSI findings are then discussed briefly with reference to the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD).

Methods
A systematic search of the ELSI literature was conducted. Via a process of abstract screening and full-text review, 288 sources of evidence were included in the review. Data extraction involved identifying the ELSI discussed in each source, which were thematically analysed to generate ELSI themes and to identify relevant linkages to the UNCRPD.

Results
Ten ELSI themes were identified as having relevant UNCRPD linkages including reproductive autonomy, issues related to cost and access, the downside of knowing about one’s genetic makeup, lagging legislation in light of the rapid advancement of genomic technologies, genetic discrimination, the stigmatisation and devaluation of people with disabilities, the potential resurgence of eugenics and the medical model of disability, and the involvement of people with disabilities in conversations about genomic technologies. These themes have relevant and direct linkages to several UNCRPD rights including equality, non-discrimination, diversity, accessibility, full participation, identity, and freedom of expression.

Conclusions
The review findings highlight that there is scope for the development of a charter on human rights specific to genomic technologies in the context of disability, which could guide ethical and socially appropriate developments in the field of genomic technologies in future.

AbstractIn the past decades, the exponential rise in fossil fuel consumption has led to a pressing need for sustainable energy solutions. This surge in fossil fuel use has not only caused severe environmental repercussions but has also raised questions about our global dependence on such non-renewable resources. Addressing these detrimental effects, NASA has urged the aeronautic industry to reduce aircraft fuel burn by a substantial 70% before 2025. As a result of comprehensive government and industry studies, electric aircraft propulsion has emerged as a pivotal focus of research. This encompasses various architectures, such as full-electric, hybrid electric, and turbo-electric systems. The aim is to significantly diminish the environmental impact of aviation and make it more sustainable for the future of passenger flight. This paper provides an overview of the latest state-of-the-art innovations in propulsion systems. It delves into the operational principles, technological requirements, ongoing research, and development efforts pertaining to all components essential for effecting this transformation in aviation technology. Additionally, the document will showcase existing commercial products, prototypes, and demonstrators to offer a comprehensive picture of the current scenario. Overall, this research is a vital step toward achieving energy sustainability and reducing the environmental footprint of the aviation industry. By exploring and advancing electric aircraft propulsion, humanity can move closer to a cleaner, greener future for air travel.
Access Security Policy Generation for Containers as a Cloud Service

Published: September 2023

AbstractThe rapid development of containerization technology comes with remarkable benefits for developers and operation teams. Container solutions allow building very flexible software infrastructures. Although lots of efforts have been devoted to enhancing containerization security, containerized environments still have a huge attack surface. Completely avoiding severe security issues have so far not been possible to achieve. However, the security problems due to vulnerabilities in for instance kernels, can be largely reduced if the container privileges are as restricted as possible. Mandatory access control is an efficient way to achieve this using for instance AppArmor. As manual AppArmor generation is tedious and error prone, automatic generation of protection profile is necessary. In previous research, a new tool for tight AppArmor profile generation was presented. In this paper we show how, in a system setting, such tool can be combined with container service testing, to provide a cloud based container service for automatic AppArmore profile generation. We present solutions for profile generation both for centrally collected and generated container logs and for log collection through a local agent. To evaluate the effectiveness of the profile generation service, we enable it on a widely used containerized web service to generate profiles and test them with real-world attacks. We generate an exploit database with 11 exploits harmful to the tested web service. These exploits are sifted from the 56 exploits of Exploit-db targeting the tested web service’s software. We launch these exploits on the web service protected by the profile. The results show that the proposed profile generation service improves the test web service’s overall security a lot compared to using the default Docker security profile. This together with the very user friendly and robust principle for setting up and running the service, clearly indicates that the approach is an important step for improving container security in real deployments.

AbstractChild abuse is a phenomenon that affects a large proportion of the world’s population and has important effects on their mental health. Although several instruments exist to measure it, they present some difficulties that require improvement. The present study started from an instrument previously developed for Mexican population (Esparza-Del Villar et al., Journal of Interpersonal Violence, 2020) to construct a new retrospective measure of abuse: the Child Abuse Scale for Adults (EAIA, Spanish initials). We worked with a total sample of 810 individuals, consisting mainly of women (> 70%) and young adults (mean age around 23 years). We conducted both traditional (exploratory and confirmatory factor analysis) and advanced (exploratory graph analysis, item response theory) procedures to obtain a short self-report measure of child abuse experiences. The EAIA evidenced a clear factor structure (CFI = .96, RSMEA = .06), as well as adequate reliability for its three subscales: sexual (ω = .91), physical (ω = .88) and emotional abuse (ω = .93). In addition, it showed partial scalar invariance between sexes. At the item level, it was observed that the items of the sexual and physical abuse subscales had greater informative capacity at high levels of maltreatment, while the items of the emotional abuse subscale showed better psychometric quality at average levels of the construct. Finally, associations were found in the expected direction between the three subscales of the EAIA and a set of psychopathological variables (depression, anxiety and suicidal ideation). In conclusion, the EAIA constitutes a promising alternative to retrospectively measure child abuse in the Mexican adult population.
Deep edge intelligence-based solution for heart failure prediction in ambient assisted living

Published: October 2023

AbstractHeart failure and heart disease prediction in real-time is a highly significant necessity for the patients living under the observation of Internet of Things-based Ambient Assisted Living systems because cardiovascular diseases are the most common fatal chronic diseases. Most of the solutions regarding heart disease prediction in the Internet of Things-based medical systems are relying on server-based predictive analysis which can appear to be complex for generating real-time prediction notifications and unreliable in case of any network interruption occurrences. The suggested edge-based solution for the prediction of heart disease from collected sensor data in real-time using a proposed lightweight deep learning technique called Oversampled Quinary Feed Forward Network (OQFFN) provides a less complex framework and more reliable notification system in case of network failure for the disease prediction which also reduces the need of forwarding all the data to the server resulting in reduced network bottleneck.
