AbstractThe Sant Genís Formation is located in the NE of the Iberian Peninsula (Catalonia, Spain) and is dated to the Priabonian (upper Eocene), being part of the evaporitic formations of the margin of the Ebro Basin. It is formed by a succession of sandy lutites, occasional limestone layers, marls, and local stratified gypsum and cherts, including the Sant Martí de Tous chert. The Sant Martí de Tous chert type is confirmed by its abundance at specific locations within the territory (NE Iberian Peninsula). This is an important raw material procurement area, as evidenced by the presence of this chert in the main prehistoric sites of the region (e.g., Abric Romaní) and the constant discovery of new sites in the area around the Sant Genís Formation, especially from the Neolithic period onwards (e.g., Cal Sitjo, La Guinardera Nord workshop). All these features, together with the great heterogeneity of the Cenozoic evaporitic cherts, prompted us to carry out a multi-proxy characterization for obtaining a valid criterion by which to identify this chert in the archaeological record. This very heterogeneity hampers the macroscopic characterization of archaeological cherts (e.g., at Abric Romaní), but through petrographic analysis we have been able to identify their origins and, albeit to a lesser extent, their lithostratigraphic unit of provenance within the formation. The complementary mineralogical and geochemical techniques applied in this study show that, although it is difficult to establish an exact origin, through intensive sampling and criteria such as the differential presence of Fe and Ca, some differences among the siliceous varieties within a formation can be detected.
A Review of Tipping Points and Precaution using HJB equations
Authors: de Zeeuw Aart 
Published: May 2023

AbstractThis paper analyzes three models in environmental economics with the property that tipping can occur in the ecological part of the model: the pollution control model where tipping suddenly shifts up the damage, the fishery model where tipping suddenly lowers the carrying capacity, and the Ramsey growth model where tipping suddenly decreases the total factor productivity. The question is whether the possibility of tipping gives rise to precaution in the sense of lower production, lower harvest, or higher accumulation of capital, respectively. The paper shows that precaution always results in the pollution control model but in the other two models, it depends on the elasticity of intertemporal substitution. In these models, the tipping point is uncertain, and the analysis employs a hazard rate that can be constant or state dependent. The paper shows that the Hamilton-Jacobi-Bellman equations are the appropriate framework to implement this hazard rate. The results are mostly known, but this paper puts the results together in a transparent way, using the HJB equations consistently. In this way, it pays tribute to this technique in optimal control that proves to be useful when tipping points can occur. Extensions to differential games are discussed at the end of each section.

Abstract
Purpose
This study aimed to examine the most important problems and needs caregivers of adult inpatients with eating disorders (EDs) are confronted with in their everyday lives. A further aim was to investigate the associations between problems, needs, involvement, and depression in carers.

Methods
Fifty-five caregivers of inpatients with EDs (26 anorexia nervosa, 29 bulimia nervosa) completed the Carers' Needs Assessment, Beck Depression Inventory, and the Involvement Evaluation Questionnaire. The relationships between variables were tested via multiple linear regressions and mediation analyses.

Results
The most frequent problem reported by caregivers was a lack of information about the course and treatment of the illness and consequent disappointment, whereas their most frequently reported needs were different forms of information and counselling. Problems, unmet needs, and worrying were especially high in parents compared to other caregivers. Involvement mediated significantly between problems (b = 0.26, BCa CI [0.03, 0.49]) as well as unmet needs (b = 0.32, BCa CI [0.03, 0.59]) of caregivers and their depressive symptoms.

Conclusion
Our findings underline the importance of including the problems and needs of caregivers of adult eating disorder patients in the planning of family and community interventions, to support their mental health.

Abstract
Purpose
Recently, the concept of successful ageing has shifted from healthy ageing to active ageing, the latter emphasising even more the subjective perspective. Active agency is a marker for better functioning. However, the concept of active ageing lacks a clear definition so far. The specific aims of the study were to identify the determinants of being actively engaged in life (BAEL), to explore the changes in BAEL over 3 decades, and to explore the prognostic value of BAEL.

Methods
This is a repeated cross-sectional cohort study of older (≥ 75 years) community-dwelling people in Helsinki in 1989 (N = 552), 1999 (N = 2396), 2009 (N = 1492), and 2019 (N = 1614). The data were gathered by a postal questionnaire at each time point. Being actively engaged in life was defined by two questions “Do you feel needed?” and “Do you have plans for the future?”, which was further converted into BAEL score.

Results
An increasing temporal trend in BAEL score was observed through the study years. Male sex, good physical functioning and subjective health, and meaningful social contacts were determinants for higher BAEL score. Active agency measured by BAEL score predicted lower 15-year mortality.

Conclusions
Older home-dwelling, urban Finnish people have become more actively engaged in recent years. The underlying causes are diverse but improved socioeconomic status observed over the study years was one of them. Social contacts and not feeling lonely were found to be determinants for being actively engaged. Two simple questions describing active engagement in life may help to predict mortality among older people.

Published: May 2023

AbstractThe Behavior Analysis Certification Board (BACB) Ethics Code states that “behavior analysts should put compliance with the law and clients’ interests first by actively working to maximize desired outcomes and minimize risk” (emphasis added; BACB, 2020, p. 5). In turn, board certified practitioners must approach the case conceptualization process in applied behavior analysis (ABA) with respect to minimizing risks to an improved quality of life (QoL). As such, ABA services must be based on an understanding of risk—risk to ensuring desired outcomes. The purpose of the current article is two-fold (1) revisit social validity and propose features of socially meaningful case conceptualization, and (2) introduce a corresponding structured risk-driven approach to ABA service delivery. A primary aim is to equip all stakeholders with readily accessible practice-related supports—ensuring clients’ rights to effective services towards an improved QoL.
Document-level relation extraction based on sememe knowledge-enhanced abstract meaning representation and reasoning
Authors: Zhao Qihui , Gao Tianhan , Guo Nan 
Published: May 2023

AbstractDocument-level relation extraction is a challenging task in information extraction, as it involves identifying semantic relations between entities that are dispersed throughout a document. Existing graph-based approaches often rely on simplistic methods to construct text graphs, which do not provide enough lexical and semantic information to accurately predict the relations between entity pairs. In this paper, we introduce a document-level relation extraction method called SKAMRR (Sememe Knowledge-enhanced Abstract Meaning Representation and Reasoning). First, we generate document-level abstract meaning representation graphs using rules and acquire entity nodes’ features through sufficient information propagation. Next, we construct inference graphs for entity pairs and utilize graph neural networks to obtain their representations for relation classification. Additionally, we propose the global adaptive loss to address the issue of long-tailed data. We conduct extensive experiments on four datasets DocRE, CDR, GDA, and HacRED. Our model achieves competitive results and its performance outperforms previous state-of-the-art methods on four datasets.

Authors: Varshney Ayush K. , Torra Vicenç 
Published: May 2023

AbstractFuzzy rule-based systems (FRBSs) is a rule-based system which uses linguistic fuzzy variables as antecedents and consequent to represent human-understandable knowledge. They have been applied to various applications and areas throughout the soft computing literature. However, FRBSs suffers from many drawbacks such as uncertainty representation, high number of rules, interpretability loss, high computational time for learning. To overcome these issues with FRBSs, there exists many extensions of FRBSs. This paper presents an overview and literature review of recent trends on various types and prominent areas of fuzzy systems (FRBSs) namely genetic fuzzy system, hierarchical fuzzy system, neuro fuzzy system, evolving fuzzy system, FRBSs for big data, FRBSs for imbalanced data, interpretability in FRBSs and FRBSs which use cluster centroids as fuzzy rules. The review is for years 2010–2021. This paper also highlights important contributions, publication statistics and current trends in the field. The paper also addresses several open research areas which need further attention from the FRBSs research community.

Published: May 2023

AbstractLithium-ion batteries (LIBs) have helped revolutionize the modern world and are now advancing the alternative energy field. Several technical challenges are associated with LIBs, such as increasing their energy density, improving their safety, and prolonging their lifespan. Pressed by these issues, researchers are striving to find effective solutions and new materials for next-generation LIBs. Polymers play a more and more important role in satisfying the ever-increasing requirements for LIBs. Polyimides (PIs), a special functional polymer, possess unparalleled advantages, such as excellent mechanical strength, extremely high thermal stability, and excellent chemical inertness; they are a promising material for LIBs. Herein, we discuss the current applications of PIs in LIBs, including coatings, separators, binders, solid-state polymer electrolytes, and active storage materials, to improve high-voltage performance, safety, cyclability, flexibility, and sustainability. Existing technical challenges are described, and strategies for solving current issues are proposed. Finally, potential directions for implementing PIs in LIBs are outlined.
Unambiguous Linkage Between the Vaccination Coverage and the Spread of COVID-19: Geostatistical Evidence from the Slovak LAU 1 Regions
Authors: Bleha Branislav , Ďurček Pavol 
Published: May 2023

AbstractThis case study refutes some controversial findings about a minor connection between the vaccination coverage and the spread of COVID-19. We try to eliminate some methodological shortcomings and risks, which are included in such previously published studies. Firstly, our selection comprises all regional units in one country. Secondly, the quality of data is basically identical in all examined regions within the country. Thirdly, all Slovak regions had an equal starting position. They were at the same stages of the COVID-19 wave, and the measures taken were analogous in all regions. Slovakia with a significantly different vaccination rates among regions is a very suitable study case. We used the empirical data at the level of its LAU 1 regions for the two latest COVID-19 waves at that time (Delta, Omicron). The methods of regression analysis and geostatistical methods were applied in the study. Indubitably, there is an obvious link between the vaccination coverage and the spread of COVID-19. We have shown that the incidence-trajectories among regions vary based on the vaccination rates. The positivity and incidence in the most vaccinated regional populations were significantly lower than in the least vaccinated regions in a whole analyzed period. Their values in the best vaccinated regions were lower by roughly 20–25 % during the delta and omicron wave-peaks. Using the spatial autocorrelation, we also managed to clearly identify a close relationship between vaccination on the one hand and standardized incidence and positivity on the other hand, although some regions deviated from this general finding.

Published: May 2023

Abstract
Objective
To describe the prevalence of factors contributing to readmission of older medical patients perceived by patients, significant others and healthcare professionals and to examine the agreement of factors contributing to readmission.

Methods
This cross-sectional survey was conducted at Horsens Regional Hospital from September 2020 to June 2021. Patients aged ≥ 65 years and who were readmitted within 30 days were included. The questionnaire covered eight themes: disease; diagnosing, treatment and care; network; organisation; communication; skills and knowledge; resources; and practical arrangements. Response groups were patients, significant others, GPs, district nurses and hospital physicians. Outcomes were the prevalence of factors contributing to 30-day readmission and inter-rater agreement between respondents.

Results
In total, 165 patients, 147 significant others, 115 GPs, 75 district nurses and 165 hospital physicians were included. The patients’ median age was 79 years (IQR 74–85), and 44% were women. The following were the most prevalent contributing factors: (1) relapse of the condition that caused the index admission, (2) the patient could not manage the symptoms or illness, (3) worsening of other illnesses or conditions, (4) the patient was not fully treated at the time of discharge and (5) the patient’s situation was too complex for the medical practice to handle. Kappas ranged from 0.0142 to 0.2421 for patient—significant other dyads and 0.0032 to 0.2459 for GP—hospital physician dyads.

Conclusion
From the perspectives of the included respondents, factors associated with the disease and its management were the most prevalent contributors to readmission for older medical patients. Agreement on the contributing factors was generally low.

Dynamic Optimization of Role Concepts for Role-Based Access Control Using Evolutionary Algorithms
Authors: Anderer Simon , Kempter Tobias , Scheuermann Bernd , Mostaghim Sanaz 
Published: May 2023

AbstractTo ensure the security of current information systems, role-based access control (RBAC) is a widely used concept. For this purpose, based on an initial assignment of permissions to users, permissions are grouped to roles, which are then assigned to users. The corresponding (NP-complete) optimization problem, the so-called role mining problem (RMP), aims at finding a minimal set of roles and a corresponding assignment of those roles to users. Previously, the RMP has been considered as a static optimization problem. However, the application of RBAC in real business use cases requires the inclusion of dynamically occurring events that reflect changes in the business environment of companies, as well as events that result from direct user interaction with the role mining process. Therefore, in this paper, we provide a comprehensive overview and classification of the most relevant events for role mining and present methods for integrating them into the framework of an evolutionary role mining algorithm. The functional performance of these methods as well as the overall performance gain of dynamic role mining compared to the static approach is then examined in a series of experiments.

AbstractClimate change is the global phenomenon of climate transformation characterized by changes in the planet’s habitual climate. The main objective of this work is to assess and predict climate change for the 2015–2100 period, in the Boufakrane river watershed, Morocco. In this study, the Statistical DownScaling Model (SDSM) method has been used to generate the climate scenarios for rainfall and temperature related to Representative Concentration Pathway (RCP) scenarios such as RCP 2.6, RCP 4.5, and RCP 8.5. For this purpose, the region’s annual, monthly, and daily rainfall records were analyzed. A rainfall index was calculated to differentiate and distinguish between dry and humid years of the climate series, and a non-parametric Pettitt’s test has been applied to determine the trend of precipitation series for the projection period. The application of Pettitt’s test with a confidence interval of 99% and a significance level of 0.05 shows a break in the 1979/80 rainfall series, with an average of 675.78 mm and 511.94 mm respectively before and after the break. The combined application of the two approaches of SDSM, and the non-parametric Pettitt test for the period 2015–2100, showed a downward trend of annual rainfall with 17.29% for RCP 2.6. While no trend was recorded for the two scenarios RCP 4.5, and RCP 8.5. Therefore, this study highlighted the importance and urgent need for developing strategies and decision-making plans for climate change adaptation for sustainable water resources management.

Published: May 2023

AbstractExploiting the fantastic features of quantum mechanics, a hyperentangled quantum network encoded in multiple degree of freedoms (DOF), e.g., polarization and orbital angular momentum DOFs, can encode more qubits per transmitted photon and offers a promising platform for many dramatic applications. Here, we demonstrate such a hyperentangled multiuser network with a fully connected network architecture by using dense wavelength division multiplexing and entanglement transfer technique. Three hyperentangled states in polarization and time-energy DOFs are multiplexed to three single mode fibers to form the fully connected network architecture. Then, three interferometric quantum gates are utilized for transferring quantum entanglement from time-energy to orbital angular momentum DOF. The experimental results reveal a high quality of the hyperentanglement of the constructed network with the entangled state fidelity of higher than 96%. Our approach can provide a novel way to construct a large-scale hyperentangled network that can support various kinds of quantum tasks like superdense coding and teleportation.

Abstract

Objectives:
To explore the health impacts of Hurricane Maria (HM) on HIV care outcomes among people living with HIV who use drugs.

Methods:
Using data from an ongoing cohort study in San Juan, Puerto Rico (Proyecto PACTo), we measured differences in HIV care outcomes (viral load, viral suppression, and CD4 counts) before and after HM using assessments conducted at 6-month intervals. Generalized estimating equations were used to assess factors associated with HIV care outcomes.

Results:
All HIV care outcomes showed a deterioration from pre-HM values to post-HM values (mean viral load increased, CD4 counts decreased, and rate of viral suppression decreased) after controlling for pre-HM sociodemographic and health characteristics. In addition to HM, age (aIRR = 1·01), being homeless (aIRR = 0·78) and having health insurance (aIRR = 1·6) were independently associated with viral suppression.

Participants:
219 participants completed follow-up visits between April 2017 and January 2018, before and after HM.

Conclusions:
People living with HIV who use drugs in Puerto Rico experienced poorer HIV outcomes following HM. Socio-environmental factors contributing to these outcomes is discussed in the context of disaster response, recovery, and program planning.
