Context.Homogeneous photometric time series spanning decades provide a unique opportunity to study the long-term cyclic behavior of active spotted stars such as our target EI Eridani. In addition, with ultraprecise space photometry data, it is possible to investigate the accompanying flare activity in detail. However, the rotation period of ≈2 days for EI Eri makes it impossible to achieve time-resolved surface images from a single ground-based observing site. Therefore, for this purpose, spectroscopic data from a multi-site observing campaign are needed.Aims.We use our photometric time series of more than 40 yr to analyze the long-term behavior of EI Eri. We investigate flare activity using photometric data obtained with the Transiting Exoplanet Survey Satellite (TESS). The MUlti-SIte Continuous Spectroscopy (MUSICOS) campaign in 1998 was designed to achieve high-resolution, multi-wavelength spectroscopic observations from many sites around the globe, which meant that uninterrupted phase coverage of EI Eri became available. We use these data to reconstruct successive surface-temperature maps of the star in order to study the changes of starspots on a very short timescale.Methods.We used long-term seasonal period analysis of our photometric time series to study changes in the rotational period. We also applied short-term Fourier-transform to look for activity cycle-like changes. We also studied the phase and frequency distribution of hand-selected flares. We applied our multi-line Doppler imaging code to reconstruct four consecutive Doppler images. These images were also used to measure surface differential rotation with our cross-correlation technique. In addition, we carried out tests to demonstrate how Doppler imaging is affected by the fact that the data came from several different instruments with different spectral resolutions.Results.Seasonal period analysis of the light curve reveals a smooth, significant change in period, possibly indicating the evolution of active latitudes. Temperature curves fromB−VandV−Ishow slight differences, indicating the activity of EI Eri is spot dominated. Short-term Fourier transform reveals smoothly changing cycles of between 4.5 and 5.5 yr and of between 8.9 and 11.6 yr. The time-resolved spotted surface of EI Eri from Doppler imaging enabled us to follow the evolution of the different surface features. Cross-correlating the consecutive Doppler maps reveals surface shear ofα= 0.036 ± 0.007. Our tests validate our approach and show that the surface-temperature distribution is adequately reconstructed by our method. The tests also indicate how accurately the cross-correlation method can reproduce the surface shear as a function of the spectral resolution.

Zusammenfassung
Hintergrund Dieser Artikel stellt eine konservierende Methode für
die Umgestaltung von Frontzähnen nach kieferorthopädischer
Behandlung vor. So können beispielsweise Zapfenzähne,
Nichtanlagen und Diastemata trotz kieferorthopädischer Behandlung zu
ästhetisch und funktionell nachteiligen Ergebnissen führen.
Neben prothetischen und chirurgischen Lösungsansätzen
rücken durch verbesserte Materialeigenschaften vermehrt auch
Kompositaufbauten in den Mittelpunkt der Therapie.
Klinischer Fall Die klinische Situation einer Patientin nach
kieferorthopädisch erfolgtem Lückenschluss aufgrund von
Nichtanlage der lateralen Inzisiven wurde mittels Abdrucks und Modellscanner in
eine Software überführt, um ein digitales Mockup zu erstellen.
Auf Grundlage dieses Modells wurde anschließend ein durchsichtiger
Silikonschlüssel fabriziert, der nach entsprechender Vorbereitung der
Zähne intraoral positioniert und über Injektionskanäle
mit einem fließfähigen Komposit befüllt wurde.
Schlussfolgerung Für die mittelfristige und minimalinvasive
Versorgung von Frontzähnen eignet sich die Komposit-Injektionstechnik
grundsätzlich sehr gut. Dabei ermöglicht das Vorgehen auch bei
komplexen Frontzahnaufbauten ästhetisch gute und reproduzierbare
Ergebnisse.

Principles for teaching sonography – current status
Authors: Bintaro Sabine , Dietrich Christoph F. , Potthoff Andrej 
Published: May 2023

AbstractSince many young medical residents require sonographic skills early on during training, increased attention has been paid to including sonography classes in undergraduate medical education, among both professional societies and medical educators responsible for medical licensing exams. Medical schools worldwide have developed and implemented a variety of ultrasound teaching formats.This article addresses evidence-based solutions to crucial challenges in planning and implementing undergraduate sonography education. In order to achieve a sustainable increase in practical sonographic competence, we suggest small-group classes with sufficient individual hands-on scanning time for each student. We recommend concentrating on a circumscribed topic and teaching it thoroughly and practically rather than superficially outlining a broad subject area. Provided that peer teachers undergo adequate training, student peer teachers are not inferior to physicians as teachers, as far as student satisfaction, theoretical knowledge and practical skills acquisition are concerned. The assessment of acquired practical skills should consist of practical examinations, such as an objective structured clinical examination (OSCE) or a direct observation of procedural skills (DOPS). In contrast to using healthy volunteers as training models, simulation trainers allow the demonstration of pathological findings in authentic sonographic images, with the disadvantages of unrealistically easy image acquisition, as well as the lack of interaction with the patient.

Published: May 2023

Abstract
Introduction Pediatric malignancy represents 5% of total cancer diagnosed in India. Due to delayed diagnosis and inaccessibility to healthcare system, the overall outcome is poor in our country. The clinicodemographic profile of childhood malignancy is well described in the Western world and in certain parts of India. The incidence of pediatric malignancy in Eastern India, especially Odisha, has not yet been reported that has motivated us to conduct such a study.
Objective This study aims to evaluate the clinicodemographic profile and pattern of childhood malignancy among pediatric patients who received the treatment at a tertiary cancer institute of Odisha.
Materials and Methods It was a retrospective observational study, carried out for a period of 8 years, from January 1, 2013 to December 31, 2020 at a tertiary cancer center in Eastern India. A total of 759 eligible childhood malignancy patients were recruited in the study. IBM SPSS v23 was used for descriptive statistical analysis, that is, number and percentage of various clinicodemographic parameters of the above patients.
Result Childhood malignancy accounted for 1.6% of all cancers reported during the above study period. The male to female ratio was 1.8:1. Out of 759 eligible childhood cancer patients, majority of patients were suffering from leukemia (173; 22.8%) followed by malignant bone tumors (137; 18.0%), and lymphoma (122; 16%). Leukemia was predominant in the age group of 0 to 14 years; lymphoma, central nervous system neoplasms, germ cell tumors malignant bone tumors, and soft tissue sarcoma (STS) were common in the age group of 10 to 18 years; neuroblastoma, retinoblastoma, and renal and hepatic tumors were seen commonly in the age group of 0 to 9 years. The most common presentation in leukemia was fever, while lymphadenopathy was the chief complaint in lymphoma. Local swelling and pain were the presenting symptoms in malignant bone tumors, while STS patients had painless swelling.
Conclusion This study provides an overview of the burden and pattern of childhood malignancy for the state of Odisha and acts as a roadmap for the clinicians to conduct further research in the field of pediatric oncology.
Navigating the Budding Researchers through Different Study Designs in Homeopathy: Part 1 of Research Method Series
Authors: Dutta Abhijit 
Published: May 2023

AbstractHomeopathy is a complementary and alternative system of medicine that has been in practice for over 200 years. Despite its widespread use, there is still debate on the effectiveness of homeopathy, and research in this area is controversial.In the era of evidence-based healthcare, the scientific community seeks high quality evidence for informed clinical decisions. In homeopathy, research awareness is limited among the practitioners and stakeholders, which results in minimum number of studies, and mostly of compromised quality. This largely contributes to the subjected criticism against the effect of homeopathy.Despite various existing reporting guidelines, methodological frameworks, and research literatures, the submissions of homeopathic research papers reflect serious flaws. In this article, we provide an overview of the research question, hypothesis, objectives, outcome selection and commonly used study designs in homeopathic research.While homeopathic research can be challenging due to the individualised nature of treatment, a properly framed research question and adequately fitted study designs can help researchers investigate the effect of homeopathic treatment and provide valuable insights into multiple fascinating areas of interest.In conclusion, this article is intended to provide the readers with a better understanding of the research process and study designs particularly relevant to homeopathy. It is hoped that this will help researchers design better studies to provide more conclusive evidence of the effects of homeopathic treatments.
Renal Cell Carcinoma in the Background of Autosomal Dominant Polycystic Kidney Disease: Report of Two Cases and Review of Literature

Published: May 2023

AbstractPatients with autosomal dominant polycystic kidney disease (ADPKD), especially those with renal failure, carry a higher risk of developing renal cell carcinoma (RCC) compared to the general population. Genetic mutations associated with ADPKD are known but a direct link associated with RCC is still controversial. We discuss the clinical course of two such patients. The first patient was diagnosed with ADPKD at the age of 10 years with an unreported tubulocystic RCC focus on his renal biopsy that was picked up on review 16 years later when he presented with vertebral metastases determined to have originated from the RCC. He was doing well on multikinase inhibitors till 4 years of diagnosis with metastatic disease when he succumbed to progressive disease after 3 lines of systemic therapy. The second patient was diagnosed with ADPKD in middle age and papillary RCC 3 years later. Within 3 months of cancer diagnosis, there was progression to metastatic disease and rapid decline despite systemic therapies. We surmise that the diagnosis of RCC may be missed in ADPKD till the advanced stages. Patients with ADPKD should be monitored regularly with imaging and biopsy if needed. Histology may be varied but once diagnosed, systemic therapies may help disease control.

Abstract
The 2021 Resolution on Oral Health by the 74th World Health Assembly supports an important health policy direction: inclusion of oral health in universal health coverage. Many healthcare systems worldwide have not yet addressed oral diseases effectively. The adoption of value-based healthcare (VBHC) reorients health services towards outcomes. Evidence indicates that VBHC initiatives are improving health outcomes, client experiences of healthcare, and reducing costs to healthcare systems. No comprehensive VBHC approach has been applied to the oral health context. Dental Health Services Victoria (DHSV), an Australian state government entity, commenced a VBHC agenda in 2016 and is continuing its efforts in oral healthcare reform. This paper explores a VBHC case study showing promise for achieving universal health coverage that includes oral health. DHSV applied the VBHC due to its flexibility in scope, consideration of a health workforce with a mix of skills, and alternative funding models other than fee-for-service.
Comparative moral principles: justifications, values, and foundations
Authors: Ylä-Anttila Tuukka 
Published: May 2023

AbstractThe article compares three influential theories used in sociology and psychology to categorize types of morality—Luc Boltanski & Laurent Thévenot’s justification theory, Shalom H. Schwartz’s basic human values theory, and Jonathan Haidt’s moral foundations theory—to simplify the complexity presented by three different categorizations, while retaining necessary nuance, and to translate the concepts of each into the language of the other two. A comparative table is presented to evaluate which categories of the three theories correspond to each other and where do theories make distinctions that are lacking from the other two. This summary framework of Comparative Moral Principles (CMP) consists of eight principles to compare, explain, and interpret practices of moral motivation and meaning-making: Liberty, Inspiration, Safety, Community, Care, Equality, Deservingness, and Competition.
Topic detection with recursive consensus clustering and semantic enrichment
Authors: De Leo Vincenzo , Puliga Michelangelo , Bardazzi Marco , Capriotti Filippo , Filetti Andrea , Chessa Alessandro 
Published: May 2023

AbstractExtracting meaningful information from short texts like tweets has proved to be a challenging task. Literature on topic detection focuses mostly on methods that try to guess the plausible words that describe topics whose number has been decided in advance. Topics change according to the initial setup of the algorithms and show a consistent instability with words moving from one topic to another one. In this paper we propose an iterative procedure for topic detection that searches for the most stable solutions in terms of words describing a topic. We use an iterative procedure based on clustering on the consensus matrix, and traditional topic detection, to find both a stable set of words and an optimal number of topics. We observe however that in several cases the procedure does not converge to a unique value but oscillates. We further enhance the methodology using semantic enrichment via Word Embedding with the aim of reducing noise and improving topic separation. We foresee the application of this set of techniques in an automatic topic discovery in noisy channels such as Twitter or social media.
Hierarchies and decision-making in groups: experimental evidence
Authors: Bessey Donata 
Published: May 2023

AbstractWhile individual decision-making is a principal research area in theoretical and experimental economics, many decisions are actually made by groups, and not by individuals. In addition, groups are often characterized by hierarchical organizational structures, but little is known about their possible effects on outcomes in economic experiments. This exploratory study investigates differences in decision-making outcomes for individuals and groups under different hierarchies using data from an incentivized economic experiment using a sample of South Korean college students and Bayesian hypothesis testing, frequentist regression analysis, and analysis of predicted probabilities for “ideal types”. It compares the choices of groups of three in lottery choices and intellective tasks under five different hierarchy types: a group without hierarchy, a hierarchy by age, by merit, by chance, and by election. A within-subjects comparison of choices as individuals and as leaders allows to control for individual differences that might matter for choices beyond the hierarchy type. Regression results show that there are no differences in the number of safe choices between the different hierarchy types, but groups with a leader assigned based on merit perform better in intellective tasks, compared to leaders assigned based on a vote, age, or a random mechanism. These findings suggest that the type of hierarchy and its perceived legitimacy might matter for the quality of outcomes in intellective tasks, with no effects found for risk attitude.
Communication in child language brokering
Authors: Angelelli Claudia V. , Ceccoli Federica 
Published: May 2023

AbstractChild Language Brokering (CLB) refers to the mediation and translation activities performed by bi/multilingual children and adolescents for their peers, family members, and/or other people belonging to their linguistic community who may not be proficient enough to communicate in the societal language. Since child language brokers engage in interpreted communicative events and implement communicative strategies, one interesting but also controversial area of CLB is the communicative role children play and the expectations of other parties about that role. In this paper we examine frequent communication strategies implemented by a child language broker and study if/how they meet the other parties’ expectations. Specifically, two child language brokering strategies are examined: replacement of a monolingual interlocutor and summarizing of the monolingual interlocutors’ statements. We also discuss child language brokers’ roles and their alignment with adults’ expectations, an innovative focus that merits deeper discussion.
Waveform uncertainty quantification and interpretation for gravitational-wave astronomy
Authors: Read Jocelyn 
Published: May 2023

Abstract
We demonstrate how to quantify the frequency-domain amplitude and phase accuracy of waveform models,

δ
A

and δφ, in a form that could be marginalized over in gravitational-wave inference using techniques currently applied for quantifying calibration uncertainty. For concreteness, waveform uncertainties affecting neutron-star inspiral measurements are considered, and post-hoc error estimates from a variety of waveform models are made by comparing time-domain and frequency-domain analytic models with multiple-resolution numerical simulations. These waveform uncertainty estimates can be compared to GW170817 calibration envelopes or to Advanced LIGO and Virgo calibration goals. Signal-specific calibration and waveform uncertainties are compared to statistical fluctuations in gravitational-wave observatories, giving frequency-dependent modeling requirements for detectors such as Advanced LIGO Plus, Cosmic Explorer, or Einstein Telescope. Finally, the distribution of waveform error for the GW170817 posterior is computed from tidal models and compared to the constraints on δφ or

δ
A

from GWTC-1 by Edelman et al. In general, δφ and

δ
A

can also be interpreted in terms of unmodeled astrophysical energy transfer within or from the source system.

Published: May 2023

Abstract
With the development of optical engineering technologies, traditional experimental courses that merely demonstrate theoretical phenomena can no longer meet the demands of optical engineers’ education. In this paper, we propose an experimental course ‘Fiber-Michelson white light interference experiment’ towards the cultivation of optical engineering undergraduates and present a fiber optic system supporting the course. The proposed course integrates fiber optics and optical engineering applications with traditional Michelson interference experimental course, and the experimental system used in the course is low in cost, easy to operate, and convenient to assemble. During the class, students work as groups and have to finish three experimental tasks including the measurements of length, curvature, and refractive index. The first-hand experiences in experiments can impress students with the Michelson optic interference theory and is conductive to developing their abilities to apply optics to engineering. Students’ feedbacks are collected by questionnaire, and students recognize the necessity and effectiveness of the course.
