First-principles calculation of electron-phonon coupling in doped KTaO3
Authors: Esswein Tobias , Spaldin Nicola A. 
Published: October 2023

Background: Motivated by the recent experimental discovery of strongly surface-plane-dependent superconductivity at surfaces of KTaO3 single crystals, we calculate the electron-phonon coupling strength, λ, of doped KTaO3 along the reciprocal space high-symmetry directions. Methods: Using the Wannier-function approach implemented in the EPW package, we calculate λ across the experimentally covered doping range and compare its mode-resolved distribution along the [001], [110] and [111] reciprocal-space directions. Results: We find that the electron-phonon coupling is strongest in the optical modes around the Γ point, with some distribution to higher k values in the [001] direction. The electron-phonon coupling strength as a function of doping has a dome-like shape in all three directions and its integrated total is largest in the [001] direction and smallest in the [111] direction, in contrast to the experimentally measured trends in critical temperatures. Conclusions: This disagreement points to a non-BCS character of the superconductivity. Instead, the strong localization of λ in the soft optical modes around Γ suggests an importance of ferroelectric soft-mode fluctuations, which is supported by our findings that the mode-resolved λ values are strongly enhanced in polar structures. The inclusion of spin-orbit coupling has negligible influence on our calculated mode-resolved λ values.

Objetivo: Analizar la asociación entre los estilos de vida y factores de riesgo para la salud que pueden suponer un abandono prematuro del trabajo, con los años de discapacidad sobrevenida estimados (ADSE) en población laboral, y calcular la correlación entre el Índice de Capacidad Laboral (ICL) y el Work Ability Score (WAS), y ambos con los ADSE y su coste económico.
Métodos: Estudio transversal en una muestra de trabajadores a los que se realizó un examen de salud. La información se recogió mediante los cuestionarios ICL y WAS, y la metodología PoRT-9LSQ. Se realizó un análisis de la asociación entre los factores de riesgo analizados y los ADSE mediante regresión lineal y análisis de la varianza (ANOVA). Se analizó la correlación entre ICL y WAS usando el coeficiente de correlación intraclase (CCI), y con los ADSE y su coste económico mediante regresión lineal ajustada.
Resultados: Se incluyeron 590 trabajadores. Los factores que más influyeron en la media de ADSE fueron el sedentarismo, la mala alimentación y el sobrepeso/obesidad, con diferencias estadísticamente significativas según sexo, turno y ocupación (p<0,05). El CCI entre ICL y WAS fue del 93,0% para una valoración excelente/buena. La regresión lineal ajustada entre ICL y los ADSE fue de 7,982-0,136xICL (p<0,05), siendo similar para el WAS.
Conclusiones: El ICL se ha mostrado útil para la predictibilidad de los ADSE en población laboral, lo que facilitará la toma de decisiones del personal sanitario para identificar personas vulnerables favoreciendo cambios en los estilos de vida y el autocuidado.
Efficient dual-wavelength metasurface for second-order differential edge detection in the ultraviolet
Authors: Chen Hao , Gui Lili , Guo Jinyang , Xu Kun 
Published: October 2023

Metasurfaces for edge detection through spatial analog calculations have attracted much attention due to advantages such as a flexible design and small footprint. Up until now, most studies have focused on single-wavelength operation in the near-infrared or visible regions, while little work has been done in the ultraviolet band. It is of significance to explore metasurfaces for edge detection in the ultraviolet band for their great potential in high-resolution imaging and lithography. Here, we propose a dual-wavelength HfO2 metasurface for edge detection working at 273 nm and 293 nm, with 25% and 72% efficiency, respectively, controlled by the linear polarization of the incident light. The efficient dual-wavelength second-order differential calculation in the ultraviolet band of the metasurface has been confirmed by 1D signal and 2D image processing. It may find applications in the fields of computer vision and bioimaging.

Published: October 2023

Thin HgCdTe/CdHgTe quantum wells (QWs) grown on alternative GaAs (013) substrates have been recently proposed as a material for coherent emitters in the mid-IR region. In this work, we develop a technological process for the fabrication of ridge microresonators in waveguide heterostructures with multiple HgCdTe QWs via photolithography and ion etching. We process two samples with different ridge heights and analyze their emission spectra measured under optical excitation. The width of the emission spectra dropped by an order of magnitude compared to the nonprocessed as-grown structure, allowing one to conclude that lasing at 9.2–7.1 µm takes place within the 8–120 K temperature range. However, both samples demonstrated faster temperature quenching of lasing than that of the single-pass stimulated emission from the nonprocessed structure, as well as a drop in the carrier lifetimes. These figures of merit are likely to be compromised not by the Q factor of the cavities, but due to defects induced during the etching process. Finally, the implications for HgCdTe-based lasers for the 3–5 µm transparency window and longer wavelengths (beyond 20 µm) are discussed.

Experimental evaluation of a latency-aware routing and spectrum assignment mechanism based on deep reinforcement learning
Authors: Hernández-Chulde C. , Casellas R. , Martínez R. , Vilalta R. , Muñoz R. 
Published: October 2023

The introduction of futuristic and challenging use cases of 5G and 6G communications will demand strict requirements in terms of high bandwidth and low latency. Optical backbone networks need to tackle these new network scenarios by offering highly efficient, flexible, and scalable technologies and solutions. In this context, elastic optical networks (EONs) have been recognized as a promising technological transport infrastructure for the future Internet since they can manage the optical spectrum with enhanced flexibility and efficiency. The service provisioning in EONs is a challenging issue to tackle since the routing and spectrum assignment (RSA) is characterized by a high degree of complexity. This work presents an approach for RSA in EONs leveraging the advantages of deep reinforcement learning (DRL) solutions. The devised approach jointly considers the constraints imposed by the optical technologies and the demanded connectivity service requirements (i.e., guaranteed bandwidth and maximum end-to-end latency) when computing and selecting the optical path and spectral resources. We first evaluate our approach through simulation experiments considering two reference network topologies, demonstrating its effectiveness in reducing the bandwidth blocking ratio, the path computation time, and the number of rejected connectivity services requiring lower latencies when compared to a baseline k-shortest path routing and first-fit spectrum allocation algorithm. Then, the trained DRL agent is integrated within a real proof of concept to attain an ML-assisted SDN control plane in the CTTC ADRENALINE testbed. The attained performance improvements highlight the potential benefits brought by using DRL mechanisms and its feasible integration within production EON transport infrastructures.
Roadblocks in education amidst global crisis—A study based in India
Authors: Dayal Surbhi , Pratibha  
Published: October 2023

Background
The outbreak of the COVID-19 pandemic compelled the closure of educational institutions and forced students to complete nearly two years of schooling online, impacting their physical and emotional development tremendously. This exploratory study investigates the wide-ranging impact of online education on Indian students during the COVID-19 pandemic and discusses the challenges exacerbated by disparities in access to digital devices and reliable internet service. The paper also focuses on the physical and mental health issues that arose in student cohorts as a result of the abrupt shift to online learning, and investigates the relationship between students’ socioeconomic status and the nature and frequency of health issues experienced by them.

Methods
A total of 832 respondents completed a 40-item survey that was administered online and through interviews. The paper analysed the impact of access to digital resources and teachers’ training in information and communication technology on the perception of the quality of education provided by the institutions. We further analysed the impact of the adoption of online educational platforms on students’ mental and physical health.

Results
The study found a positive relationship between the number of hours spent online, and the physical and mental health issues experienced by students. Participants reported an overall higher perception of stress and anxiety, loss of concentration, and dissatisfaction with the quality of education. Our data suggest that COVID-19 has exacerbated the digital divide.

Discussion
Urgent investments are needed to provide universal access to reliable internet services, and to develop a pedagogy that supports an agile and adaptable educational system, capable of providing effective learning and evaluation, while supporting students’ physical and mental health.

Authors: Thomson Kimberly C. , Jenkins Emily , Gill Randip , Hastings Katherine G. , Richardson Chris G. , Gagné Petteni Monique , McAuliffe Corey , Gadermann Anne M. 
Published: October 2023

Background
Mental health impacts of the COVID-19 pandemic have not been felt equally within populations. Parents with children living at home were early on identified as a population at heightened mental health risk, with concerns about the potential long-term impacts of the pandemic on parents’ mental health, family functioning, and children’s well-being. This study investigates impacts of the pandemic on parents’ psychological distress, contextual sources of distress, and associations with family functioning nearly two years into the pandemic.

Methods and findings
Data were drawn from a national cross-sectional survey of adults living in Canada in November and December 2021 that was representative by age, gender, household income, and region. Parents with children < 18 years old living at home (N = 553) reported their experiences of psychological distress, pandemic-related stressors, coping mechanisms, and family functioning (changes in parent-child interactions, children’s anxiety). Chi-square tests, logistic regression, and linear regression analyses examined sociodemographic inequities in parents’ levels of psychological distress, sources and mitigating mechanisms of distress, and associations between psychological distress and family functioning. Nearly two years into the pandemic, parents with children at home reported nearly double pre-pandemic population estimates of moderate to severe psychological distress. Psychological distress was more frequently reported among parents with pre-existing mental health conditions, disabilities, and financial stressors. Parents with greater psychological distress reported increases in negative parent–child interactions due to the pandemic and higher anxiety among their children.

Conclusions
This study identifies sustained negative impacts of the pandemic on parents’ mental health and family functioning in Canada nearly two years into the pandemic, despite high vaccine uptake and declining infection rates. Disparities in financial stress, social support structures, and pre-existing mental health were identified as underlying sources of psychological distress. These results highlight that meaningful responses to promote mental health among parents and families must address social and structural inequities.
Understanding satisfaction and dissatisfaction of patients with telemedicine during the COVID-19 pandemic: An exploratory qualitative study in primary care
Authors: Pogorzelska Karolina , Marcinowicz Ludmila , Chlabicz Slawomir 
Published: October 2023

Background
Due to the COVID-19 pandemic, healthcare organizations had to face challenging circumstances and modify the usual modality of service provision, introducing telehealth services in their routine patient care to lessen the risk of direct human-to-human exposure. Patients expressed concerns about personal visits to healthcare units and the possibility of accessing telemedicine turned out to be an effective tool for the continuity of care. Due to the limited experience with telemedicine before the COVID-19 pandemic in Poland, we sought to fill this gap by studying the experiences of Polish patients. Our study aimed to understand how patients define satisfaction and dissatisfaction with telemedicine during the COVID-19 pandemic in primary care.

Material and methods
Twenty semi-structured interviews with primary care patients in the Podlaskie Voivodeship, Poland were conducted to understand satisfaction with telemedicine.
Interview transcripts were analyzed using qualitative content analysis. The qualitative content analysis process involved familiarizing ourselves with the data, extracting text regarding satisfaction and dissatisfaction with the teleconsultation, condensing it into meaningful units assigning codes to them, and organizing codes into subcategories and categories. The entire analysis process was done through reflection and discussion until a consensus was reached between the researchers.

Results
From the participants’ perspective, satisfaction with telemedicine was associated with receiving enough space to express their concerns. It was reported that they trusted their primary care physicians and felt comfortable during telemedicine consultations. Participants noted that connecting with a known, trusted doctor was more important than having a face-to-face visit with an unfamiliar physician. In our study, the participants equated satisfaction with treatment effectiveness. It was emphasized that in the event of unknown or unstable conditions, patients would prefer to be seen in person and receive a physical examination.

Conclusion
In our research telemedicine met with a positive reception and was recognized by the majority of patients who made use of it as a valuable channel of contact with a primary care physician. In order to increase the level of patient satisfaction, the focus should be on improving aspects such as physician engagement and showing empathy during telemedicine, as well as providing complete, exhaustive information on the treatment process. Respecting patient needs and preferences during performing telemedicine visits is the goal of patient-centered care.
Handling of time delays in system identification with regularized FIR models
Authors: Kösters Tarek , Illg Christopher , Nelles Oliver 
Published: October 2023

AbstractSystem identification with finite impulse response (FIR) models has been recently revised by introducing specific forms of regularization in the estimation. By utilizing prior knowledge of the dynamic process under investigation different kernels for regularization can be derived. However, the dynamical processes considered are mainly restricted to time-delay free systems. Therefore, in this paper we propose two novel methods to handle the time-delay case. Both methods incorporate the time-delay estimation in the hyperparameter optimization of the regularized FIR models. The first method is built on a single kernel (SK) and the second utilizes a multiple kernel (MK) approach. Simulations on different dynamical systems show the superior behavior of both methods in comparison to standard regularization methods, whereupon the MK outperforms the SK approach.
Japanese tertiary students’ perceptions of group work with explicit scaffolding
Authors: Morgan Emily 
Published: October 2023

Abstract
Over several decades, small group work has been studied in first language (L1) and second or subsequent language (L2) education, including English language learning contexts. Group work has been shown to be beneficial to language learning and general learning. L2 English students from non-student-centred educational backgrounds have limited experience of group work and often have poor attitudes towards it. Student attitudes can affect how well a student performs and engages with group work, so that poor attitudes may prevent them from accessing the full range of benefits of this learning method. Group work is common in English-medium education contexts, including university settings and work settings. Therefore, it is important to ensure that L2 English language students wishing to study or work in English-medium contexts develop a positive attitude towards group work. This can be done through scaffolding. In the present project, scaffolded group work was used in an English writing program for L2 students at a Japanese university. Student perceptions of group work were collected throughout the program to assess the change of attitude over time. Results showed that students’ perceptions of group work changed positively, particularly regarding personal learning and collaborative processes. Implications for language learning are discussed.
Green synthesis, characterization, and evaluation of antibacterial activities of cobalt nanoparticles produced by marine fungal speciesPericonia prolifica

Published: October 2023

AbstractBio-nanotechnology provided an ecofriendly synthesis route for various metal nanoparticles by utilizing different biological systems, especially microorganisms, which act as an alternative to the physical and chemical methods. Cobalt nanoparticles (CoNPs) were synthesized byPericonia prolifica(Anast.) from intertidal decayed wood samples from the mangrove treeAvicennia marina(Forsk.) of Tarout Island, located in the Arabian Gulf Sea of Saudi Arabia. CoNPs were characterized by X-ray diffraction, transmission electron microscopy, Fourier-transform infrared spectroscopy, and atomic force microscope. The extract of the culture ofP. prolificawas used as a bio-reductant agent, during which the culturing process proved to have great potential to be applied on an industrial scale, as it was a time-saving, inexpensive, and adequate amount of biomass being produced at the end of the process. A preliminary antibacterial test against one Gram-positive resistant bacteria (i.e., Methicillin-resistantStaphylococcus aureus) and other Gram-negative resistant bacteria was performed using a disk diffusion assay. The antibacterial results witnessed the key role that metal size plays in causing higher activity and also in causing severe damage to the bacterial cells by inactivating its membrane permeability, leading to bacterial cell death.
Mutual volatility transmission between assets and trading places
Authors: Masuhr Andreas , Trede Mark 
Published: October 2023

Abstract
This article proposes a framework to model the mutual volatility transmission between multiple assets and multiple trading places in different time zones. The model is estimated using a dataset containing daily returns of three stock indices – the MSCI Japan, the EuroStoxx 50, and the S&P 500 – each traded at three major trading places: the stock exchanges in Tokyo, London, and New York. Strong volatility transmission effects can be observed between New York and Tokyo, whereas current volatility in New York mostly depends on past volatility in New York. For the assets in consideration, spillovers are strong across trading zones, but weak across assets, suggesting a close connection between market places but only a loose volatility link between international stock indices. Volatility impulse response functions indicate a long-lasting and comparably large response of volatility in Tokyo, whereas they suggest a quicker volatility decay in London and New York.
Meinungsfreiheit und Moralismus
Authors: Neuhäuser Christian 
Published: October 2023

Abstract
In Germany, like in many other liberal countries, there is an extensive public discourse about freedom of speech being at risk. It will be insisted in this contribution that on the one hand, freedom of speech as a subjective right of basic law is not endangered. On the other hand, it should be acknowledged that in public discourse moralistic exaggerations are quite common. Against this background, the paper asks when different opinions are to be respected and at what point it is permitted or even required to condemn them as immoral. The basic argument advanced here is that opinions should be respected as long as they are based in or at least supported by reasonable moral theories. Those opinions that do not have such a support can be labelled as properly immoral and criticized as such.
Ein Exzerpt aus Die Religion innerhalb der Grenzen der bloßen Vernunft aus dem Schiller-Nachlass
Authors: Sommer Niklas 
Published: October 2023

Abstract
In this paper, I shall draw attention to an as yet unpublished excerpt of a part of Kant’s Religionsschrift (Religion within the Limits of Reason Alone) written by an unknown author that has been found in Schiller’s literary remains, labelled by the Goethe-Schiller-Archiv as ‘general working material’. A note on the excerpt itself marks it as pertaining to the first edition of Kant’s text. A few questions arise from that find: First, which parts of Kant’s text does the excerpt represent? Secondly, does it really refer to the first edition of the Religionsschrift? Thirdly and fourthly, who authored it and how did it get into Schiller’s hands? I shall answer the first two questions by providing a tentative transcription based on which I am going to argue that the excerpt treats the first pages of the first part of Kant’s Religionsschrift and does not refer to the first, but indeed the second edition from 1794. As far as the last two questions are concerned, no definitive answer can be given. Instead I detail Schiller’s endeavours and personal contacts around the time of the publication of the Religionsschrift’s second edition, which might provide some clues as to the possible author for future investigations. Furthermore I outline the impact Kant’s discourse had on Schiller’s own philosophical works, i.e. his essay On Grace and Dignity.
