Some global topological properties of a free boundary problem appearing in a two dimensional controlled ruin problem
Authors: Grandits Peter 
Published: June 2023

AbstractIn this paper a two-dimensional Brownian motion (modeling the endowment of two companies), absorbed at the boundary of the positive quadrant, with controlled drift, is considered. The volatilities of the Brownian motions are different. We control the drifts of these processes and allow that both drifts add up to the maximal value of one. Our target is to choose the strategy in a way, s.t. the probability that both companies survive is maximized. It turns out that the state space of the problem is divided into two sets. In one set the first company gets the full drift, and in the other set the second one. We describe some topological properties of these sets and their separating curve.

Published: June 2023

AbstractWe investigate a method to extract response functions (dynamical polarisabilities) directly from a bound-state approach applied to calculations of perturbation-induced reactions. The use of a square-integrable basis leads to a response in the form of a sum of $$\delta $$
δ
functions. We integrate this over energy and fit a smooth function to the resulting stepwise-continuous one. Its derivative gives the final approximation to the physical response function. We show that the method reproduces analytical results where known, and analyse the details for a variety of models. We apply it to some simple models, using the stochastic variational method as the numerical method. Albeit we find that this approach, and other numerical techniques, have some difficulties with the threshold behavior in coupled-channel problems with multiple thresholds, its stochastic nature allows us to extract robust results even for such cases.
Oral squamous carcinoma cell lysates provoke exacerbated inflammatory response in gingival fibroblasts
Authors: Sordi Mariane Beatriz , Panahipour Layla , Gruber Reinhard 
Published: June 2023

Abstract

Objectives
To study whether damaged epithelial cells and gingival fibroblast could affect the expression of inflammatory cytokines in healthy cells.

Materials and methods
Cell suspensions were submitted to different treatments to obtain the lysates: no treatment (supernatant control), sonication, and freeze/thawing. All treatments were centrifuged, and the supernatants of the lysates were used for experimentation. Cell viability assays, RT-qPCR of IL1, IL6 and IL8, IL6 immunoassay, and immunofluorescence of NF-kB p65 were applied to verify the inflammatory crosstalk of damaged cells over healthy plated cells. Furthermore, titanium discs and collagen membranes were treated with lysates and checked for IL8 expression by RT-qPCR.

Results
Lysates obtained upon sonication or freeze/thawing of oral squamous carcinoma cell lines provoked a robust increase in the expression of IL1, IL6, and IL8 by gingival fibroblasts, which was confirmed by IL6 immunoassays. Lysates obtained from the gingival fibroblasts failed to increase the expression of inflammatory cytokines in oral squamous carcinoma cells. Additionally, oral squamous carcinoma cell lysates caused the activation of the NF-kB signalling cascade in gingival fibroblasts as indicated by the phosphorylation and nuclear translocation of p65. Finally, oral squamous carcinoma cell lysates adhered to the titanium and collagen membrane surfaces and increased IL8 expression by gingival fibroblasts growing in these materials.

Conclusions
Injured oral epithelial cells can release factors that incite gingival fibroblasts to become pro-inflammatory.

Clinical relevance
Injuries affecting the oral mucosa generate epithelial fragments that may reach the underlying connective tissue and provoke inflammation. These injuries are routinely caused by mastication, sonication for teeth cleaning, teeth preparation, prostheses maladaptation, and implant drilling.

Abstract
Background
Reference blood pressure (BP) values for Japanese children based on a large number of measurements by auscultation have not yet been established.

Methods
This was a cross-sectional analysis of data from a birth-cohort study. The data from the sub-cohort study conducted for children at the age of 2 years in the Japan Environment and Children’s Study from April 2015 to January 2017 were analyzed. BP was measured via auscultation using an aneroid sphygmomanometer. Each participant was measured in triplicate, and the average value of two consecutive measurements with a difference of less than 5 mmHg was recorded. The reference BP values were estimated using the lambda–mu–sigma (LMS) method and compared with those obtained via the polynomial regression model.

Results
Data from 3361 participants were analyzed. Although the difference between the estimated BP values by the LMS and the polynomial regression model was small, the LMS model was more valid based on the results of the fit curve of the observed values and regression models for each model. For 2-year-old children with heights in the 50th percentile, the 50th, 90th, 95th, and 99th percentile reference values of systolic BP (mmHg) for boys were 91, 102, 106, and 112, and that for girls were 90, 101, 103, and 109, respectively, and those of diastolic BP for boys were 52, 62, 65, and 71, and that for girls were 52, 62, 65, and 71, respectively.

Conclusion
The reference BP values for 2-year-old Japanese children were determined based on auscultation and were made available.

AbstractRemote reconnaissance missions are promising solutions for the assessment of earthquake-induced structural damage and cascading geological hazards. Space-borne remote sensing can complement in-field missions when safety and accessibility concerns limit post-earthquake operations on the ground. However, the implementation of remote sensing techniques in post-disaster missions is limited by the lack of methods that combine different techniques and integrate them with field survey data. This paper presents a new approach for rapid post-earthquake building damage assessment and landslide mapping, based on Synthetic Aperture Radar (SAR) data. The proposed texture-based building damage classification approach exploits very high resolution post-earthquake SAR data integrated with building survey data. For landslide mapping, a backscatter intensity-based landslide detection approach, which also includes the separation between landslides and flooded areas, is combined with optical-based manual inventories. The approach was implemented during the joint Structural Extreme Event Reconnaissance, GeoHazards International and Earthquake Engineering Field Investigation Team mission that followed the 2021 Haiti Earthquake and Tropical Cyclone Grace.
Modelling the reduction of quartz in a quartz–carbon pellet

Published: June 2023

AbstractTraditional refining of silicon generates carbon dioxide emissions that are released into the atmosphere. An alternative process under experimental exploration uses quartz particles coated in a layer of porous carbon as the raw material, instead of lumps of quartz and carbon. The quartz–carbon pellets are processed at a lower temperature than in an industrial furnace, and hence, different chemical reactions are dominant, reducing the greenhouse gas emissions. The quartz core shrinks as it is consumed, and the carbon is converted to silicon carbide, which can subsequently be processed into silicon. We develop a model for chemical and transfer processes within a single quartz–carbon pellet. We derive governing equations for the concentration of silicon monoxide, carbon monoxide, and carbon dioxide, and conservation equations on the moving quartz interface. Furthermore, we then focus on a reduced model in an industrially relevant distinguished limit, and solve numerically the resulting leading-order system. We show examples of reaction-limited behaviour as well as diffusion-limited behaviour. Both regimes are physically admissible due to the large potential range of the parameters. Finally, we sweep through the parameter space, and characterize the dynamics based on the utilization of the carbon and the silicon yield. We find that the diffusion-limited regime is best for carbon utilization and silicon yield, as the silicon monoxide reacts with the carbon before it is transported out of the pellet.
Understanding the Risks and Individual Difference Factors Associated with Engagement in Monetised (Play-to-Earn) Gaming

Published: June 2023

AbstractPlay-to-earn (P2E) is a new form of monetised gaming based on blockchain and crypto-currency technology. Such games offer opportunities to combine gaming with speculative investment through the purchase of tradable in-game currencies and assets (non-fungible tokens). In this paper, we investigate the profile of people most likely to be attracted to this emerging form of gaming. A sample of 560 participants aged between 18-65 (M = 28.3, SD = 8.3) were recruited via Prolific to complete an online survey that included measures of gaming (Petry’s Internet Gaming Disorder Scale) and gaming risk (Problem Gambling Severity Index), measures of gaming motivation and impulsivity. Other existing engagement in gaming monetization as well as digital asset ownership was also assessed. P2E interest was associated with higher gambling risk scores, but not with internet gaming disorder. P2E gamers also scored higher on extrinsic motivation and monetised gaming was generally associated with higher impulsivity. The results suggest that P2E may be attractive to those with a pre-existing interest in financially risky activities. Policy implications include the increasing need to monitor the growth of digital asset technology and the increasing convergence of gambling, financial speculation and gaming and the potential for increasing financial harm in gaming populations.
Perceived impacts of the Fridays for Future climate movement on environmental concern and behaviour in Switzerland

Published: June 2023

AbstractCalling for increased action on climate change, Fridays for Future (FFF) quickly gained momentum around the world and became highly visible through strikes and protests in more than 150 countries. Considering its scale and magnitude, questions about the impact of this newly emerging climate movement arise. This article is based on a survey investigating the perception of Swiss residents (N = 1206) of how the FFF movement and Greta Thunberg’s climate activism changed their environmental awareness and behaviour. We found that the Swiss public by and large perceives Greta Thunberg and the FFF movement positively, and a considerable share of participants report that Greta Thunberg (30%) and the FFF activism (23%), respectively, positively influenced their environmental concern and behaviour. Structural equation modelling revealed that the strength of the behaviour change motivation depended mainly on how a participant evaluated the FFF movement and Greta Thunberg. The latter was influenced positively by general environmental attitudes, and education level and negatively by the acceptance of justifications for environmentally harmful behaviours. Participants reported environmentally positive changes most frequently in private sphere behaviours, particularly in the domains of mobility, consumption and waste, whereas few changes in public sphere behaviour were reported. Next to increased awareness and motivation gains, also the reinforcement of existing pro-environmental behaviour was reported. Although the influence on sympathisers was stronger, some of those sceptical of the climate strike movement also reported behaviour changes, indicating that the unconvinced have to some extent been reached.

SamenvattingGezonde School-adviseurs (GSA) van de GGD ondersteunen scholen bij het implementeren van de Gezonde School-aanpak. Omdat iedere school uniek is, is een contextgerichte manier van ondersteunen noodzakelijk. Om GSA’s bewust te maken van en aan te moedigen om te werken met zo’n contextgerichte aanpak is een training ontwikkeld. Wij beschrijven hoe deze training door middel van cocreatie tot stand is gekomen en reflecteren op dit proces. Het ontwikkelproces bestond uit drie fasen: 1) inventarisatie van taken en behoeften van GSA, 2) ontwikkeling van de training, en 3) een pilottest van de training. Alle fasen hebben plaatsgevonden in cocreatie tussen onderzoekers, GSA’s uit de praktijk en het landelijke programmateam Gezonde School. Evaluatie van de twee gehouden pilots laat zien dat de ontwikkelde training goed wordt ontvangen (algemeen rapportcijfer: respectievelijk 7,4 en 8,4). Een reflectie op het ontwikkelingsproces laat zien hoe groot het belang is van cocreatie gedurende het gehele proces. Hierdoor kon continu rekening worden gehouden met de dagelijkse praktijk van de GSA’s en hun wensen en behoeften. Ook kon er zo voor gezorgd worden dat de training goed aansluit bij het huidige landelijke deskundigheidsbevorderingsaanbod voor GSA’s en de Gezonde School-aanpak in het algemeen.
Sharing the knowledge: exploring cultural heritage through an ontology-based platform

Published: June 2023

AbstractThe exponential growth of data has made ontology modeling an up-and-coming research area for knowledge representation. One of the domains of interest is represented by Cultural Heritage, in which modeling of environments, such as archaeological parks, could lead to their protection and enhancement. In this scenario, the valuable dataset on the Naples Urban Archaeological Park (PAUN) is of particular interest. Due to its peculiarity, the database could benefit from innovative techniques for retrieving the information, representing a large part of the information contained within the DatabencArt platform, which collects data on Campania's cultural heritage. This paper aims to introduce an ontology-based approach to improve data retrieval, which could help expert users in the field (archaeologists, art historians, geologists, etc.). Scholars need to be able to easily compare the information. To this end, a semantic search is able to transform a vast amount of data into linked concepts. We mapped all concepts according to the ArCo ontology and equipped the DatabencArt platform with a semantic query layer, making the information accessible through ArCo ontology's properties. To evaluate the proposed approach, we designed an experimental campaign involving expert users to assess the results obtained in the system's queries through Sparql queries. The obtained results are promising.

AbstractAmazonian swamp forests remove large amounts of carbon dioxide (CO2) but produce methane (CH4). Both are important greenhouse gases (GHG). Drought and cultivation cut the CH4 emissions but may release CO2. Varying oxygen content in nitrogen-rich soil produces nitrous oxide (N2O), which is the third most important GHG. Despite the potentially tremendous changes, GHG emissions from wetland soils under different land uses and environmental conditions have rarely been compared in the Amazon. We measured environmental characteristics, and CO2, CH4 and N2O emissions from the soil surface with manual opaque chambers in three sites near Iquitos, Peru from September 2019 to March 2020: a pristine peat swamp forest, a young forest and a slash-and-burn manioc field. The manioc field showed moderate soil respiration and N2O emission. The peat swamp forests under slight water table drawdown emitted large amounts of CO2 and CH4. A heavy post-drought shower created a hot moment of N2O in the pristine swamp forest, likely produced by nitrifiers. All in all, even small changes in soil moisture can create hot moments of GHG emissions from Amazonian wetland soils, and should therefore be carefully monitored.
Are the Arab Gulf States Ready for HIV/AIDS Discussions? A Qualitative Thematic Analysis
Authors: Alageel Samah , Alomair Noura 
Published: June 2023

Abstract
Introduction
There is a lack of awareness of HIV/AIDS nature, mode of transmission, and prevention amongst Muslims, with socio-cultural and religious factors contributing to the lack of awareness. This research was aimed at examining people’s perceptions and views of HIV/AIDS awareness content in the Gulf Council Cooperation (GCC) region.

Methods
We performed a qualitative thematic analysis of comments posted on an HIV/AIDS educational video by “Salamatak” programme in the GCC region on three social media platforms (YouTube, Twitter, and Instagram).

Results
A total of 486 comments were included in the analysis. Public responses to HIV/AIDS awareness content varied depending on perceived commonality of HIV and religiosity in the GCC community. Some comments were against the video, and public outrage towards the video content prevailed. The main reasons for this outrage were the absence of the moral/religious message and lack of cultural sensitivity. However, some comments supported a harm reduction approach, emphasising that the promotion of abstinence only is unrealistic and ineffective for HIV prevention. It was apparent from the public’s response to the video that stigma and discrimination against people living with HIV/AIDS are highly prevalent in the community.

Conclusions
Religiously and culturally sensitive sexual health content is lacking in the region, and the need for tailored intervention was highlighted in our findings. Stigma and discrimination against people living with HIV are common in the GCC countries.

Policy Implications
A collaborative effort between policymakers, public health practitioners, opinion makers, and researchers is needed to tackle the HIV epidemic and reduce stigma and discrimination against people living with HIV in the region.
Allergy to the cat—from diagnosis to management
Authors: Jensen-Jarolim Erika , Jensen Sebastian Alexander , Bergmann Karl-Christian 
Published: June 2023

Abstract
Background
In allergology practice, efficient counselling of cat owners is often frustrating because the topic of allergen avoidance is mostly a “no-go” and there are only few studies on allergen immunotherapy that prove its efficacy. In the end, what patients are mostly offered in allergy consultations are allergen reduction measures and symptomatic therapy.

Results
Sensitisation to the main cat allergen Fel d 1 occurs more frequently in atopic conditions and then represents a risk for allergic rhinitis and asthma. Current guidelines are therefore cautious about the first-time acquisition of a cat in the first months of life in atopic families. However, sensitisation occurs in many cases even without contact with an own cat at home.
Conversely, it has been observed in adult patients that in the case of high Fel d 1 exposure immunological tolerance can also develop through the induction of specific IgG4. The fact that many cat allergic patients keep their animals despite diagnosis is, however, partly due to the psychological phenomenon of coping.

Conclusion
In this review, we present current literature and facts that should make everyday life easier for patients, even without giving up the animal. We also review best practices in the management of cat allergy and present new management options and concepts from the development pipeline that our patients are eagerly awaiting.
Applying Systems Thinking to Inform Decentralized Clinical Trial Planning and Deployment

Published: June 2023

AbstractRecently, there has been a growing interest in understanding how decentralized clinical trial (DCT) solutions can mitigate existing challenges in clinical development, particularly participant burden and access, and the collection, management, and quality of clinical data. This paper examines DCT deployments, emphasizing how they are integrated and how they may impact clinical trial oversight, management, and execution. We propose a conceptual framework that employs systems thinking to evaluate the impact on key stakeholders through a reiterative assessment of pain points. We conclude that decentralized solutions should be customized to meet patient needs and preferences and the unique requirements of each clinical trial. We discuss how DCT elements introduce new demands and pressures within the existing system and reflect on enablers that can overcome DCT implementation challenges. As stakeholders look for ways to make clinical research more relevant and accessible to a larger and more diverse patient population, further robust and granular research is needed to quantify the impact of DCTs empirically.
