Effect of Ag/CuS nanoparticles loading to enhance linear/nonlinear spectroscopic and electrical characteristics of PVP/PVA blends for flexible optoelectronics
Authors: Alharthi Sami S. , Badawi Ali 
Published: August 2023

AbstractDue to the novel physicochemical properties of polymeric nanocomposites (PNCs), a remarkable role of PNCs has been accomplished in plenty of flexible optoelectronic applications. Solution cast procedure has been performed to prepare different contents (0.1, 0.5, 1.0, 5.0, and 10 wt%) of Ag1.6Cu0.2S (ACS) incorporated in PVP/PVA blend. Fourier transforms infrared and scanning electron microscope measurements were carried out to investigate the influence of ACS on PVP/PVA structure and morphology. UV–visible spectrophotometry technique was applied to examine PVP/PVA optical properties modifications. Spectroscopic analysis reveals that direct/indirect optical bandgap of PVP/PVA host shrinks from 5.21/4.95 eV (PVP/PVA0) to 4.87/4.54 eV (PVP/PVA10). Moreover, obvious enrichments in the whole linear/nonlinear optical parameters are achieved by ACS doping. For example, refractive index and dielectric constants of PVP/PVA are increased from 1.69 and 2.87 to 1.91 and 3.63 (PVP/PVA10). While two orders of magnetite enhancement in nonlinear third‐order susceptibility are achieved via 10% ACS doping. The electrical performance of ACS PNCs has been explored, which discloses remarkable enrichments in PVP/PVA DC‐electrical conductivity () and activation energy. The obtained structural, spectroscopic and electrical investigations prove that ACS PNCs could play an efficient role in plenty of optoelectronic applications.Highlights

Published: August 2023

AbstractA 9‐month‐old, female, entire border collie was presented as an emergency for unilateral epistaxis, rapidly evolving to bilateral, and lethargy of sudden onset. A moderate broncho‐interstitial pattern was present on thoracic radiographs, particularly in the caudo‐dorsal lung lobes. Haematology and coagulation parameters (prothrombin time, partial thromboplastin time, fibrinogen) were within normal range. Multiple larvae (L1) of Angiostrongylus vasorum were identified both on flotation (Ovassay technique) and sedimentation (McKenna technique). The dog was treated with fenbendazole (50 mg/kg) for 15 days. On re‐examination, 4 days after completion of treatment, faecal analysis was negative and thoracic radiographs were improved. This case reports epistaxis as the main clinical finding in a young dog infested with A. vasorum, in the southwest of France, where this parasite is endemic. If bleeding diatheses are increasingly reported in angiostrongylosis, epistaxis is an unusual presentation, especially as the sole clinical sign of bleeding, in a dog with normal coagulation parameters.

AbstractInformed by decades of literature, water interventions increasingly deploy “gender‐sensitive” or even “gender transformative” approaches that seek to redress the disproportionate harms women face from water insecurity. These efforts recognize the role of gendered social norms and unequal power relations but often focus narrowly on the differences and dynamics between cisgender (cis) men and women. This approach renders less visible the ways that living with water insecurity can differentially affect all individuals through the dynamics of gender, sexuality, and linked intersecting identities. Here, we first share a conceptual toolkit that explains gender as fluid, negotiated, and diverse beyond the cis‐binary. Using this as a starting point, we then review what is known and can be theorized from current literature, identifying limited observations from water‐insecure communities to identify examples of contexts where gendered mechanisms (such as social norms) differentiate experiences of water insecurity, such as elevating risks of social stigma, physical harm, or psychological distress. We then apply this approach to consider expanded ways to include transgender, non‐binary, and gender and sexual diversity to deepen, nuance and expand key thematics and approaches for water insecurity research. Reconceptualizing gender in these ways widens theoretical possibilities, changes how we collect data, and imagines new possibilities for effective and just water interventions.This article is categorized under:Human Water > Value of WaterEngineering Water > Water, Health, and SanitationHuman Water > Water as Imagined and RepresentedHuman Water > Methods
Feasibility of CSAC-Assisted GNSS Receiver Fingerprinting
Authors: Lin Qianwen , Schön Steffen 
Published: August 2023

AbstractInterference and jamming of Global Navigation Satellite System (GNSS) signals can induce inaccurate Position, Velocity and Time (PVT) information, resulting in crucial integrity and even security issues. The poor stability and accuracy of the GNSS receivers’ internal clocks, i.e. quartz oscillators, additionally impact the situation by hindering the detection of spoofing signals. High-precision atomic clocks are used to enhance PVT results, however, their bulk, weight and energy consumption constrain their deployment scenarios. Miniature atomic clocks (MAC) present a promising alternative that trades off between frequency stability and size/weight limitations of an atomic clock.This paper investigates the potential of chip-scale atomic clocks (CSAC) as external clocks of GNSS receivers for fingerprinting the receivers in both static and dynamic environments. Fingerprinting is characterized by the clock’s physical behavior expressed by Allan Deviation (ADEV) or Time Interval Error (TIE), both of which relate to the clocks’ frequency stability. Thus, unique receiver clock features serve as clock fingerprints. The optimal combinations of features are explored by three feature extraction methods. We gathered GNSS data in diverse scenarios, consisting of a four-day static experiment, a car and a flight experiment as well as the corresponding static experiment for comparison. Results indicate that CSAC-aided fingerprinting is feasible in static conditions, achieving an overall accuracy (OA) of 90

across the three methods. One of the three methods is proven effective to handle clock fingerprinting in dynamic conditions, but yielded a comparably lower OA than in static conditions.

Published: August 2023

AbstractThe twenty-first century has proven that data are the new gold. Artificial intelligence (AI) driven technologies might potentially change the clinical practice in all medical specialities, including orthopedic surgery. AI has a broad spectrum of subcomponents, including machine learning, which consists of a subdivision called deep learning. AI has the potential to increase healthcare delivery, improve indications and interventions, and minimize errors. In orthopedic surgery. AI supports the surgeon in the evaluation of radiological images, training of surgical residents, and excellent performance of machine-assisted surgery. The AI algorithms improve the administrative and management processes of hospitals and clinics, electronic healthcare databases, monitoring the outcomes, and safety controls. AI models are being developed in nearly all orthopedic subspecialties, including arthroscopy, arthroplasty, tumor, spinal and pediatric surgery. The present study discusses current applications, limitations, and future prospective of AI in foot and ankle surgery.

ZusammenfassungDer Begriff „Morbus Castleman“ umfasst eine Gruppe von seltenen lymphoproliferativen Krankheitsbildern, die histopathologische Gemeinsamkeiten in der Lymphknotenbiopsie aufweisen. Erst seit wenigen Jahren stehen diagnostische Kriterien sowie ein spezifischer ICD-10-Code zur Verfügung. Mit den eingangs aufgeführten Fallbeispielen wird veranschaulicht, dass es für die Diagnosestellung einer engen Zusammenarbeit zwischen Klinikern und Pathologen bedarf. Für eine optimale histopathologische Beurteilung ist der Pathologe zudem auf die Entnahme eines vollständigen Lymphknotens angewiesen. Vor der hinsichtlich der Prognose und Therapie bedeutsamen Abgrenzung eines potenziell fatal verlaufenden, multilokulären idiopathischen Morbus Castleman von der resezierbaren, lokalisierten Form setzt die frühzeitige Diagnose aber voraus, dass das Krankheitsbild differenzialdiagnostisch überhaupt erst in Betracht gezogen wird. Verschiedene Immunphänomene und Überlappungen mit u. a. autoimmun bedingten Erkrankungen können die Wahrscheinlichkeit von Fehldiagnosen oder unerkannten Fällen auch im klinischen Alltag des Rheumatologen erhöhen. Intention der vorliegenden Übersicht war es daher, auch auf die Ähnlichkeiten mit differenzialdiagnostisch relevanten, Autoimmunerkrankungen hinzuweisen und Situationen aufzuzeigen, die eine Überprüfung der bisherigen Diagnose rechtfertigen.
Neuroprotective Effect of Hydrogen Sulfide Subchronic Treatment Against TBI-Induced Ferroptosis and Cognitive Deficits Mediated Through Wnt Signaling Pathway

Published: August 2023

AbstractEmerging evidence shows that targeting ferroptosis may be a potential therapeutic strategy for treating traumatic brain injury (TBI). Hydrogen sulfide (H2S) has been proven to play a neuroprotective role in TBI, but little is known about the effects of H2S on TBI-induced ferroptosis. In addition, it is reported that the Wnt signaling pathway can also actively regulate ferroptosis. However, whether H2S inhibits ferroptosis via the Wnt signaling pathway after TBI remains unclear. In this study, we first found that in addition to alleviating neuronal damage and cognitive impairments, H2S remarkably attenuated abnormal iron accumulation, decreased lipid peroxidation, and improved the expression of glutathione peroxidase 4, demonstrating the potent anti-ferroptosis action of H2S after TBI. Moreover, Wnt3a or liproxstatin-1 treatment obtained similar results, suggesting that activation of the Wnt signaling pathway can render the cells less susceptible to ferroptosis post-TBI. More importantly, XAV939, an inhibitor of the Wnt signaling pathway, almost inversed ferroptosis inactivation and reduction of neuronal loss caused by H2S treatment, substantiating the involvement of the Wnt signaling pathway in anti-ferroptosis effects of H2S. In conclusion, the Wnt signaling pathway might be the critical mechanism in realizing the anti-ferroptosis effects of H2S against TBI.
Graphical Abstract
TBI induces ferroptosis-related changes characterized by iron overload, impaired antioxidant system, and lipid peroxidation at the chronic phase after TBI. However, NaHS subchronic treatment reduces the susceptibility to TBI-induced ferroptosis, at least partly by activating the Wnt signaling pathway.
Experts’ perspectives on the sustainability and risks of freely applicable MSWI bottom ash: a Q-methodology study in the Netherlands
Authors: Piltz Gunilla , Annema Jan Anne , Pesch Udo 
Published: August 2023

AbstractExperts in the Netherlands have lately debated the novel policy idea to freely apply municipal solid waste incineration bottom ash (MSWIBA). In this paper, we map this ambivalent and unforeseeable, subjective, expert debate. This will help policymaking because more knowledge on subjective expert viewpoints and perceptions allows for clustering conflict and consent as well as gaps in common understanding in this complex debate. We applied Q-methodology which resulted in four distinct perspectives in the expert debate that reveal insights into the social licence to operate and into the legitimacy of the novel bottom ash regime. The freely applicable quality of BA itself is accepted in all perspectives. Conflicting views were found about new risks, trust and socio-political acceptance of the novel BA applications. An important practical contribution of this study is that a higher acceptance of the freely applicable MSWI BA quality in the Netherlands within the expert community can be achieved if the new risks of the free application regime are tackled. We are the first to use Q-methodology in this field, and our academic contribution is that we show that this method can be a helpful tool to unravel complex expert debates also related to MSWI BA applications.

The Late Iron Age in Switzerland: a review of anthropological, funerary, and isotopic studies
Authors: Cooper Christine , Milella Marco , Lösch Sandra 
Published: August 2023

AbstractThe Iron Age in continental Europe is a period of profound cultural and biological importance with heterogeneous trends through space and time. Regional overviews are therefore useful for better understanding the main cultural and biological patterns characterizing this period across the European regions. For the area of modern Switzerland, a rich archeological and anthropological record represents the Late Iron Age. However, no review of the main anthropological and funerary patterns for this period is available to date. Here we assess the available demographic, paleopathological, funerary, and isotopic data for the Late Iron Age in the Swiss territory, and summarize the cultural and biological patterns emerging from the available literature. Finally, we highlight a series of research avenues for future studies.
MDIW-13: a New Multi-Lingual and Multi-Script Database and Benchmark for Script Identification
Authors: Ferrer Miguel A. , Das Abhijit , Diaz Moises , Morales Aythami , Carmona-Duarte Cristina , Pal Umapada 
Published: August 2023

AbstractScript identification plays a vital role in applications that involve handwriting and document analysis within a multi-script and multi-lingual environment. Moreover, it exhibits a profound connection with human cognition. This paper provides a new database for benchmarking script identification algorithms, which contains both printed and handwritten documents collected from a wide variety of scripts, such as Arabic, Bengali (Bangla), Gujarati, Gurmukhi, Devanagari, Japanese, Kannada, Malayalam, Oriya, Roman, Tamil, Telugu, and Thai. The dataset consists of 1,135 documents scanned from local newspaper and handwritten letters as well as notes from different native writers. Further, these documents are segmented into lines and words, comprising a total of 13,979 and 86,655 lines and words, respectively, in the dataset. Easy-to-go benchmarks are proposed with handcrafted and deep learning methods. The benchmark includes results at the document, line, and word levels with printed and handwritten documents. Results of script identification independent of the document/line/word level and independent of the printed/handwritten letters are also given. The new multi-lingual database is expected to create new script identifiers, present various challenges, including identifying handwritten and printed samples and serve as a foundation for future research in script identification based on the reported results of the three benchmarks.
The Engagement Problem: a Review of Engagement with Digital Mental Health Interventions and Recommendations for a Path Forward
Authors: Lipschitz Jessica M. , Pike Chelsea K. , Hogan Timothy P. , Murphy Susan A. , Burdick Katherine E. 
Published: August 2023

Abstract
Purpose of the review
Digital mental health interventions (DMHIs) are an effective and accessible means of addressing the unprecedented levels of mental illness worldwide. Currently, however, patient engagement with DMHIs in real-world settings is often insufficient to see a clinical benefit. In order to realize the potential of DMHIs, there is a need to better understand what drives patient engagement.

Recent findings
We discuss takeaways from the existing literature related to patient engagement with DMHIs and highlight gaps to be addressed through further research. Findings suggest that engagement is influenced by patient-, intervention-, and system-level factors. At the patient level, variables such as sex, education, personality traits, race, ethnicity, age, and symptom severity appear to be associated with engagement. At the intervention level, integrating human support, gamification, financial incentives, and persuasive technology features may improve engagement. Finally, although system-level factors have not been widely explored, the existing evidence suggests that achieving engagement will require addressing organizational and social barriers and drawing on the field of implementation science.

Summary
Future research clarifying the patient-, intervention-, and system-level factors that drive engagement will be essential. Additionally, to facilitate an improved understanding of DMHI engagement, we propose the following: (a) widespread adoption of a minimum necessary 5-element engagement reporting framework, (b) broader application of alternative clinical trial designs, and (c) directed efforts to build upon an initial parsimonious conceptual model of DMHI engagement.
ARTour: an augmented reality collaborative experience for enhancing tourism
Authors: Elshahawy Menna , Magdy Safa , Sharaf Nada 
Published: August 2023

AbstractSerious games have been recently used for different purposes; a few of them have been developed to support cultural heritage purposes. Pandemics, for instance, change a lot in people’s lives and cause some changes, such as social distancing and lower mobility. Additionally, individuals with physical challenges do not always have the opportunity to experience heritage sites as if they were there. Hence, arises the need for applications that encourage the precautionary measures required without totally isolating the users in similar conditions. The existing serious games in the literature have proven effective for teaching cultural heritage and enhancing tourists’ experiences while at the heritage site. However, less serious games focused on giving the tourists a similar experience, but in the comfort of their homes. Therefore, this study discusses the design, development, and evaluation of ARTour. ARTour is a collaborative serious game that increases players’ engagement and enhances the overall experience, without exposing them to danger during pandemics or similar situations. The player can choose between existing heritage sites, and a timeline, in order to get the full experience.
Optimizing adaptive stepped-care interventions to change adults’ health behaviors: A systematic review
Authors: Roddy McKenzie K. , Pfammatter Angela F. , Mayberry Lindsay S. 
Published: August 2023

AbstractChronic diseases are ubiquitous and costly in American populations. Interventions targeting health behavior change to manage chronic diseases are needed, but previous efforts have fallen short of producing meaningful change on average. Adaptive stepped-care interventions, that tailor treatment based on the needs of the individual over time, are a promising new area in health behavior change. We therefore conducted a systematic review of tests of adaptive stepped-care interventions targeting health behavior changes for adults with chronic diseases. We identified 9 completed studies and 13 research protocols testing adaptive stepped-care interventions for health behavior change. The most common health behaviors targeted were substance use, weight management, and smoking cessation. All identified studies test intermediary tailoring for treatment non-responders via sequential multiple assignment randomized trials (SMARTs) or singly randomized trials (SRTs); none test baseline tailoring. From completed studies, there were few differences between embedded adaptive interventions and minimal differences between those classified as treatment responders and non-responders. In conclusion, updates to this work will be needed as protocols identified here publish results. Future research could explore baseline tailoring variables, apply methods to additional health behaviors and target populations, test tapering interventions for treatment responders, and consider adults’ context when adapting interventions.

Abstract

Objective:
The aim of this study was to evaluate how relationships between guardians and domestic animals were established and their possible effects during the COVID-19 pandemic period in Brazil.

Methods:
Data were collected by completing an online questionnaire. Throughout the national territory, 2002 people completed the questionnaire, while respecting social distancing from January 20, 2021, to March 20, 2021. The inclusion and exclusion criteria were ‘to own pets’ or ‘those who had them during the period of quarantine’ in Brazil. The data obtained were treated qualitatively through discourse analysis and content analysis, while the quantitative data were tabulated by the questionnaire application platform itself.

Results:
The results showed that 97% of the participants were affected by the coronavirus pandemic in Brazil and that of these, 95.5% stated that their pet was important to overcome and bear bad feelings during the period of social isolation. It was possible to observe through the participants’ reports through the online questionnaire that the relationships with their pets were deepened during the pandemic period, and that these had an important role in overcoming bad emotions caused by social distancing.

Conclusion:
It was concluded that due to these relationships, behaviors such as anxiety and sadness were reduced and the pets themselves also showed an increase in affective behaviors in relation to their guardians.
