Published: August 2024

Distributed online monitoring of grid voltage is crucial for ensuring power quality, providing a foundational data layer for effective grid management. Piezoelectric grating optical voltage sensing presents a cost-effective solution with high bandwidth and long-distance transmission capabilities. This paper introduces an open-loop optimization approach that leverages the gate recurrent unit (GRU) and dual-grating demodulation principles to enhance the real-time response accuracy and extend the measurement range of piezoelectric-based optical voltage sensors. Experiments conducted within a 2.8 kV sensing range analyze the voltage response and spectral characteristics. After applying corrections, the sensor achieves a linearity of 99.93%, with a maximum deviation of 2.07% and a maximum hysteresis of 3.33%. This method significantly enhances real-time response accuracy and optimizes the utilization of the sensor’s nonlinear measurement range, advancing the application of optical voltage sensors in power grids.

Two-dimensional (2D) perovskites exhibit enhanced thermal stability compared to three-dimensional perovskites, especially the emerging 2D Dion–Jacobson (DJ) phase perovskite. However, the heat transfer mechanisms in DJ phase perovskites are rarely reported. Herein, we determine thermal conductivities of (PDA)(FA)

+ 1 films with n = 1−6 by time-domain thermoreflectance. The measured results indicate that the thermal conductivities of these films are extremely low, showing a trend from decline to rise with increasing n values, and reaching to the lowest when n = 2. We measure the propagation of acoustic phonons in films with n = 1−3 by time-domain Brillouin scattering and find phonon velocity plays a key role in the thermal conductivity, which can be explained by the mismatch of spring constants between the inorganic layer and the organic layer using the bead-spring model. The gradually increasing thermal conductivity for larger n values is attributed to the gradual transformation of the grain orientation from horizontal to vertical, which is demonstrated by the grazing-incidence wide-angle x ray scattering (GIWAXS) results. Our work deepens the understanding of the thermal transport process in 2D DJ phase perovskite films and provides insights into thermal management solutions for their devices.

ZusammenfassungDie rasante Entwicklung digitaler Technologien hat den Bedarf an schneller und effizienter Softwareentwicklung in Organisationen verstärkt. In diesem Kontext haben No- und Low-Code Plattformen (NLCPs) transformative Potenziale entfaltet, indem sie Mitarbeitenden ohne umfassende Programmierkenntnisse und außerhalb der IT-Abteilung ermöglichen, eigenständig digitale Innovationen zu entwickeln. Diese Mitarbeitenden, als Citizen Developer (CD) bezeichnet, nutzen NLCPs als primäre digitale Tools, was Organisationen ermöglicht, ihre Innovationsfähigkeit durch den Einbezug von CD in das Konzept von mitarbeitergetriebenen Innovationen bottom-up zu fördern. Dieser Artikel untersucht die Problematik an der Schnittstelle zwischen Ideengenerierung und -umsetzung, bei der reguläre Mitarbeitende zwar Ideen entwickeln, diese aber mangels Programmierkenntnissen nicht ohne Unterstützung, beispielsweise der IT-Abteilung, umsetzen können. Durch eine systematische Literaturrecherche wurden die Befähigung von CD zur Entwicklung von mitarbeitergetriebenen Innovationen sowie die dabei auftretenden Wirkfaktoren analysiert. Zu den zentralen Erkenntnissen zählen die Identifizierung und Beschreibung von jeweils vier Förderfaktoren (zum Beispiel geringere Einstiegshürden) und Hemmfaktoren (zum Beispiel begrenzte Funktionalität von NLCPs) im Bottom-up-Entwicklungsprozess von CD. Zudem wurden fünf praxisorientierte Handlungsempfehlungen zur Integration von NLCPs für CD in Organisationen abgeleitet. Diese Empfehlungen umfassen die Etablierung eines IT-Governance-Rahmenwerks, die Förderung CD-unterstützender Organisationsstrukturen, der Sicherstellung von IT-Kollaboration und abteilungsübergreifender Zusammenarbeit sowie das Angebot von Schulungsmaßnahmen. Darüber hinaus wurden fünf Anwendungsbereiche generativer künstlicher Intelligenz ermittelt, die CD unterstützen und befähigen können. Diese umfassen die Beschreibung und Generierung von Programmcode, die Erstellung von Prototypen(-designs), die Automatisierung von Routineaufgaben sowie die Unterstützung kreativer Prozesse zur Lösungsfindung.

Published: August 2024

In this randomized, double-blind, sham-controlled trial of Cerebellar Stimulation for Aphasia Rehabilitation (CeSAR), we will determine the effectiveness of cathodal tDCS (transcranial direct current stimulation) to the right cerebellum for the treatment of chronic aphasia (>6 months post stroke). We will test the hypothesis that cerebellar tDCS in combination with an evidenced-based anomia treatment (semantic feature analysis, SFA) will be associated with greater improvement in naming untrained pictures (as measured by the change in Philadelphia Picture Naming Test), 1-week post-treatment, compared to sham plus SFA. We will also evaluate the effects of cerebellar tDCS on naming trained items as well as the effects on functional communication, content, efficiency, and word-retrieval of picture description, and quality of life. Finally, we will identify imaging and linguistic biomarkers to determine the characteristics of stroke patients that benefit from cerebellar tDCS and SFA treatment. We expect to enroll 60 participants over five years. Participants will receive 15, 25-minute sessions of cerebellar tDCS (3–5 sessions per week) or sham tDCS combined with 1 hour of SFA treatment. Participants will be evaluated prior to the start of treatment, one-week post-treatment, 1-, 3-, and 6-months post-treatment on primary and secondary outcome variables. The long-term aim of this study is to provide the basis for a Phase III randomized controlled trial of cerebellar tDCS vs sham with concurrent language therapy for treatment of chronic aphasia.
Trial registration: The trial is registered with ClinicalTrials.gov NCT05093673.

Purpose
Sarcopenia is considered to be an important predictor of adverse outcomes following spinal surgery, but the specific relationship between the two is not clear. The purpose of this meta-analysis is to systematically review all relevant studies to evaluate the impact of sarcopenia on spinal surgery outcomes.

Methods
We systematically searched PubMed, Embase and the Cochrane Library for relevant articles published on or before January 9, 2023. The pooled odds ratio (OR) with 95% confidence intervals (CIs) was calculated in a random effects meta-analysis. The main outcome was the risk of adverse outcomes after spinal surgery, including adverse events and mortality. This systematic review and meta-analysis was conducted following the PRISMA guidelines to evaluate the impact of sarcopenia on spinal surgery outcomes. In addition, we also conducted a subgroup analysis and leave-one-out sensitivity analyses to explore the main sources of heterogeneity and the stability of the results.

Results
Twenty-four cohort studies, with a total of 243,453 participants, met the inclusion criteria. The meta-analysis showed that sarcopenia was significantly associated with adverse events (OR 1.63, 95% CI 1.17–2.27, P < 0.001) but was no significantly associated with mortality (OR 1.17, 95% CI 0.93–1.46, P = 0.180), infection (OR 2.24, 95% CI 0.95–5.26, P < 0.001), 30-day reoperation (OR 1.47, 95% CI 0.92–2.36, P = 0.413), deep vein thrombosis (OR 1.78, 95% CI 0.69–4.61, P = 0.234), postoperative home discharge (OR 0.60, 95% CI 0.26–1.37, P = 0.002) and blood transfusion (OR 3.28, 95% CI 0.74–14.64, P = 0.015).

Conclusion
The current meta-analysis showed that patients with sarcopenia have an increased risk of adverse events and mortality after spinal surgery. However, these results must be carefully interpreted because the number of studies included is small and the studies are significantly different. These findings may help to increase the clinicians’ awareness of the risks concerning patients with sarcopenia to improve their prognosis.

Introduction
In recent years, the concept of epistemic trust has emerged as a critical factor in understanding psychopathology, particularly within the context of personality disorders. A self-report instrument, the Epistemic Trust, Mistrust, and Credulity Questionnaire (ETMCQ), has demonstrated its validity among English and Italian adult populations. However, extending its applicability to adolescents is essential for comprehending the role of epistemic trust in the development of mental disorders. The aim of this study was to validate the ETMCQ within the Italian adolescent demographic.

Methods
Data were gathered from a wide selection of middle and high schools across Italy. The data collection started on 01/03/2022 and ended on 30/06/2022. Besides the ETMCQ (Study 1 = 662 participants, 12–18 years old, M = 15.56, SD = 2.20; 324 females, 338 males), we also administered other self-report instruments measuring mentalization, emotional dysregulation, general levels of psychopathology, and interpersonal trust in a smaller groups (Study 2 = 417 participants, aged from 12–19 years old, M = 15.64; SD = 2.08; 249 females, 168 males).

Results
Our findings provide empirical validation for the theoretical framework concerning the role of epistemic trust in psychological functioning and substantiate the validity of ETMCQ as a measure to assess it among teenagers.

Conclusions
The ETMCQ is a valid and promising instrument for adolescent populations; its ease and brevity of administration could make it a valuable tool both in clinical and research contexts, shedding light on the role of epistemic trust in mental health.

Aims
Most glucose self-monitoring devices have been developed with high-income countries in mind. We developed a target product profile (TPP) for new glucose self-monitoring technologies for users in low- and middle-income countries (LMICs).

Methods
A draft TPP including 39 characteristics was developed by an expert group including diabetes specialists, device specialists, and people with diabetes, incorporating findings from qualitative research in LMICs. Each characteristic had minimal and optimal requirements for two use cases, frequent and sporadic use. Characteristics requiring refinement were identified via online survey. Characteristics with agreement level <90% for any requirement were reviewed by the expert group and amended as appropriate.

Results
One characteristic (shelf life) had agreement <75% (both requirements for both use cases). Characteristics with agreement ≥75% and <90% for the frequent use case included infrastructure level, measurement cycle, duration of use before replacement, interchangeability, and calibration (both requirements), and activity log and price per month to end payer (minimal requirement). Intended use (both requirements), accuracy, and price per month to end payer (optimal requirement) had agreement ≥75% and <90% for the sporadic use case.

Conclusions
This TPP will inform developers on requirements for glucose self-monitoring technologies for LMICs, and support decision-makers in evaluating existing devices.

Purpose
This study formed the development stage of a population-based survey aiming to: (i) understand the needs and experiences of people affected by cancer in Queensland, Australia and (ii) recruit a pool of participants for ongoing cancer survivorship research. The current study aimed to co-design and test a single qualitative survey question and study invitation materials to maximise acceptability of, and participation in, the survey and future research.

Methods
Fifty-two community members, including cancer survivors and caregivers, participated across 15 co-design workshops and 20 pretest interviews. During workshops, participants generated and refined ideas for an open-ended survey question and provided feedback on a study invitation letter. The use of a single, open-ended question aims to minimise participant burden while collecting rich information about needs and experiences. The research team then shortlisted the question ideas and revised study invitation materials based on workshop feedback. Next, using interviews, community members were asked to respond to a shortlisted question to test its interpretability and relevance and to review revised invitation materials. Content analysis of participant feedback was used to identify principles for designing study materials.

Results
Principles for designing qualitative survey questions were identified from participant feedback, including define the question timeframe and scope; provide reassurance that responses are valid and valued; and use simple wording. Principles for designing study invitation materials were also identified, including communicate empathy and sensitivity; facilitate reciprocal benefit; and include a ‘human element’. The qualitative survey question and study invitation materials created using these principles were considered relevant and acceptable for use in a population-based survey.

Conclusions
Through community consultation and co-design, this study identified principles for designing qualitative data collection and invitation materials for use in cancer survivorship research. These principles can be applied by other researchers to develop study materials that are sensitive to the needs and preferences of community members.

Background
Sequential population-based household serosurveys of SARS-CoV-2 covering the COVID-19 pre- and post-vaccination periods are scarce in Brazil. This study investigated seropositivity trends in the municipality of São Paulo.

Methods
We conducted seven cross-sectional surveys of adult population-representative samples between June 2020 and April 2022. The study design included probabilistic sampling, test for SARS-CoV-2 antibodies using the Roche Elecsys anti-nucleocapsid assay, and statistical adjustments for population demographics and non-response. The weighted seroprevalences with 95% confidence intervals (CI) were estimated by sex, age group, race, schooling, and mean income study strata. Time trends in seropositivity were assessed using the Joinpoint model. We compared infection-induced seroprevalences with COVID-19 reported cases in the pre-vaccination period.

Results
The study sample comprised 8,134 adults. The overall SARS-CoV-2 seroprevalence increased from 11.4% (95%CI: 9.2–13.6) in June 2020 to 24.9% (95%CI: 21.0–28.7) in January 2021; from 38.1% (95%CI: 34.3–41.9) in April 2021 to 77.7% (95%CI: 74.4–81.0) in April 2022. The prevalence over time was higher in the subgroup 18–39 years old than in the older groups from Survey 3 onwards. The self-declared Black or mixed (Pardo) group showed a higher prevalence in all surveys compared to the White group. Monthly prevalence rose steeply from January 2021 onwards, particularly among those aged 60 years or older. The infection-to-case ratios ranged from 8.9 in June 2020 to 4.3 in January 2021.

Conclusions
The overall seroprevalence rose significantly over time and with age and race subgroup variations. Increases in the 60 years or older age and the White groups were faster than in younger ages and Black or mixed (Pardo) race groups in the post-vaccination period. Our data may add to the understanding of the complex and changing population dynamics of the SARS-CoV-2 infection, including the impact of vaccination strategies and the modelling of future epidemiological scenarios.
Green synthesis of zinc oxide nanoparticles using Terminalia arjuna bark extract: structural, optical and photocatalytic study
Authors: Saha Suvankar , Mochahari Prince Kumar 
Published: August 2024

Abstract
Zinc oxide (ZnO) nanoparticles have been successfully synthesized by using Terminalia arjuna bark extract via a green route. Structural analysis using X-ray diffraction confirmed the prepared samples are crystalline having hexagonal wurtzite structure with space group P63
mc and average crystallite size is found to be 8.93 nm. Rietveld refinement of the data was carried out using Material Analysis Using Diffraction (MAUD) software and reliability parameters of the refinement have been obtained. Optical properties of the sample investigated by ultraviolet – visible diffuse reflectance spectroscopy reveal an absorption peak to lie at 348 nm and the direct optical band gap energy using Kubelka–Munk function is found to be 3.20 eV. Morphological investigation using scanning electron microscopy revealed that ZnO nanoparticles are nearly spherical and agglomerated. Energy-dispersive X-ray spectrometry analysis showed the presence of Zn and O only. Transmission electron microscopy imaging confirmed the predominant hexagonal structure of the prepared nanoparticles having average particles size of 9.66 nm, which is in agreement with the X-ray diffraction result. Fourier transform infrared spectroscopy was used to identify the functional groups and different vibrational modes present in the sample. The photocatalytic activity of the prepared ZnO nanoparticles was studied using methylene blue (MB) dye under a single wavelength UV light source (λ = 254 nm). The degree of degradation of MB solution was about 56 % within 120 min of illumination to UV light and the degradation reaction follows first order kinetics with rate constant 0.00434 min−1.
Flexible silver nanowire-polymer conductive films for electrophysiological detection
Authors: Liu Benyan 
Published: August 2024

Abstract
This study employed polydimethylsiloxane and silver nanowire (AgNW) to prepare polymer films for electrocardiography and electromyography sensing. Two approaches were employed to prepare AgNW-based polymer films. In the first approach, AgNW was embedded in polydimethylsiloxane through polymer infiltration. In the second approach, AgNW was applied to the surface of the polymer. The fabricated polymer films were effectively employed in electrocardiography and electromyography measurements, revealing efficiency comparable to traditional silver/silver chloride wet electrodes. The presented approaches are inexpensive and suited to mass production and thus hold great promise in the fabrication of polymer electrodes for medical monitoring.
The rise of advanced practice provider independence bills: a misguided attempt to address the physician shortage
Authors: Bohler Forrest , Peters Garrett , Aggarwal Nikhil , Harvey Kyle , Bohler J. David 
Published: August 2024

Abstract
In the past decade, the rise of state legislation that allows for advanced practice provider (APP) independence has grown steadily across the country. Most recently, Montana has enacted House Bill 313, which allows for physician assistant independent practice in primary care services. This is a concerning trend because there is a multitude of studies that demonstrate worsened patient outcomes and increased healthcare expenditures for care delivered by nonphysicians. There are also many unintended consequences that are likely to occur due to this inappropriate expansion of scope of practice for APPs. In this commentary, we outline the ramifications that are likely to occur in states such as Montana that enact legislation that expands the scope of practice for nonphysicians.
