Yet Another Sunshine Mystery: Unexpected Asymmetry in GeV Emission from the Solar Disk
Authors: Arsioli Bruno , Orlando Elena 
Published: February 2024

Abstract
The Sun is one of the most luminous γ-ray sources in the sky and continues to challenge our understanding of its high-energy emission mechanisms. This study provides an in-depth investigation of the solar disk γ-ray emission, using data from the Fermi Large Area Telescope spanning 2008 August to 2022 January. We focus on γ-ray events with energies exceeding 5 GeV, originating from 0.°5 angular aperture centered on the Sun, and implement stringent time cuts to minimize potential sample contaminants. We use a helioprojection method to resolve the γ-ray events relative to the solar rotation axes and combine statistical tests to investigate the distribution of events over the solar disk. We found that integrating observations over large time windows may overlook relevant asymmetrical features, which we reveal in this work through a refined time-dependent morphological analysis. We describe significant anisotropic trends and confirm compelling evidence of energy-dependent asymmetry in the solar disk γ-ray emission. Intriguingly, the asymmetric signature coincides with the Sun’s polar field flip during the cycle 24 solar maximum, around 2014 June. Our findings suggest that the Sun’s magnetic configuration plays a significant role in shaping the resulting γ-ray signature, highlighting a potential link between the observed anisotropies, solar cycle, and the solar magnetic fields. These insights pose substantial challenges to established emission models, prompting fresh perspectives on high-energy solar astrophysics.

Abstract
On 2022 September 26, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the efficacy of a kinetic impactor for planetary defense by changing the orbital period of Dimorphos by 33 minutes. Measuring the period change relied heavily on a coordinated campaign of lightcurve photometry designed to detect mutual events (occultations and eclipses) as a direct probe of the satellite’s orbital period. A total of 28 telescopes contributed 224 individual lightcurves during the impact apparition from 2022 July to 2023 February. We focus here on decomposable lightcurves, i.e., those from which mutual events could be extracted. We describe our process of lightcurve decomposition and use that to release the full data set for future analysis. We leverage these data to place constraints on the postimpact evolution of ejecta. The measured depths of mutual events relative to models showed that the ejecta became optically thin within the first ∼1 day after impact and then faded with a decay time of about 25 days. The bulk magnitude of the system showed that ejecta no longer contributed measurable brightness enhancement after about 20 days postimpact. This bulk photometric behavior was not well represented by an HG photometric model. An HG

2 model did fit the data well across a wide range of phase angles. Lastly, we note the presence of an ejecta tail through at least 2023 March. Its persistence implied ongoing escape of ejecta from the system many months after DART impact.

Authors: Zhou Wan , Yuan Xiao-Jing , Li Jie , Wang Wei , Zhang Hao-Qiang , Hu Yuan-Yuan , Ye Shan-Dong 
Published: February 2024

BACKGROUND
Early screening and accurate staging of diabetic retinopathy (DR) can reduce blindness risk in type 2 diabetes patients. DR’s complex pathogenesis involves many factors, making ophthalmologist screening alone insufficient for prevention and treatment. Often, endocrinologists are the first to see diabetic patients and thus should screen for retinopathy for early intervention.
AIM
To explore the efficacy of non-mydriatic fundus photography (NMFP)-enhanced telemedicine in assessing DR and its various stages.
METHODS
This retrospective study incorporated findings from an analysis of 93 diabetic patients, examining both NMFP-assisted telemedicine and fundus fluorescein angiography (FFA). It focused on assessing the concordance in DR detection between these two methodologies. Additionally, receiver operating characteristic (ROC) curves were generated to determine the optimal sensitivity and specificity of NMFP-assisted telemedicine, using FFA outcomes as the standard benchmark.
RESULTS
In the context of DR diagnosis and staging, the kappa coefficients for NMFP-assisted telemedicine and FFA were recorded at 0.775 and 0.689 respectively, indicating substantial intermethod agreement. Moreover, the NMFP-assisted telemedicine’s predictive accuracy for positive FFA outcomes, as denoted by the area under the ROC curve, was remarkably high at 0.955, within a confidence interval of 0.914 to 0.995 and a statistically significant P -value of less than 0.001. This predictive model exhibited a specificity of 100%, a sensitivity of 90.9%, and a Youden index of 0.909.
CONCLUSION
NMFP-assisted telemedicine represents a pragmatic, objective, and precise modality for fundus examination, particularly applicable in the context of endocrinology inpatient care and primary healthcare settings for diabetic patients. Its implementation in these scenarios is of paramount significance, enhancing the clinical accuracy in the diagnosis and therapeutic management of DR. This methodology not only streamlines patient evaluation but also contributes substantially to the optimization of clinical outcomes in DR management.
Interpretacija kulturne dediščine s pomočjo mitov in pravljic, drugi del
Authors: Perko Verena 
Published: February 2024

Prispevek obravnava interpretacijo dediščine z uporabo mitov in pravljic. Besedilo je razdeljeno na dva dela, prvi del, posvečen interpretaciji, je bil objavljen v prejšnji številki revije. Drugi del je posvečen mitom in pravljicam kot sredstvu interpretacije.
Miti veljajo za prvobitno obliko razlage sveta. Članek obravnava njihovo družbeno vlogo v preteklih družbah in pojasnjuje njihovo temeljno vlogo v psihosocialni strukturi človeka. S kulturno-zgodovinskim pristopom je orisana njihova primordialna vloga. Mitološke zgodbe so služile kot razlaga kozmosa, reda in zakonov, vzpostavljale so moralno in etično podlago sobivanja skupnosti. Filozofski in psihoanalitični pristop izpostavljata terapevtski naboj narativnega blaga. Obravnavana je arhetipska in transcendentna narava mita ter utemeljen njegov odsev v fluidnih pomenih materialne kulture. Miti in pravljice so del kulturnega in zgodovinskega izročila ter kot rdeča nit povezujejo sodobnost s preteklostjo.
Miti in pravljice imajo v procesih interpretacije vlogo semantičnega sistema, ki olajšuje integracijo dediščine časovno in kulturno oddaljenih obdobij v sodobnost. Pripovedovanje zgodb razpira dialoški prostor in spodbuja javnost k aktivnemu sodelovanju.
Raziskava je interdisciplinarna, temelji na heritologiji, hermenevtiki, psihoanalizi, mitoloških in kulturnozgodovinskih študijah.

Este artigo é uma pesquisa bibliográfica que explora o papel da escola, do professor e do aluno diante das práticas tecnológicas digitais e seus riscos no contexto escolar. Destaca-se o uso das tecnologias na educação, enfatizando a importância de orientar os alunos sobre seu uso responsável. Apesar das vantagens das Tecnologias de Informação e Comunicação na educação, a equidade ainda é um desafio. Medidas estão sendo adotadas em alguns Estados brasileiros, como a introdução da disciplina “cultura digital” no ensino médio, alinhada à Base Nacional Comum Curricular. Práticas digitais nas escolas oferecem benefícios, como acesso a recursos educacionais e colaboração global, mas também trazem riscos, como cyberbullying e acesso a conteúdo inadequado. Ensinar sobre o uso ético da internet e combater as Fake News são fundamentais. O avanço tecnológico e a exposição constante nas redes sociais geram preocupações com a privacidade dos dados pessoais. É essencial orientar os alunos sobre a proteção de sua privacidade e o uso adequado das redes sociais. A formação de cidadãos digitais conscientes é uma responsabilidade compartilhada entre escola, família e sociedade.

Published: February 2024

This work is devoted to increasing economic efficiency when using two-stream air distributors that form a swirled and flat stream while providing a dynamic microclimate in compressed conditions of industrial premises. The design of a two-jet air distributor is proposed, which forms a swirled and flat laying air jet, that provides intensive attenuation of air flow velocity and temperature in stationary and variable mode. Measures aimed at saving cold energy are considered, namely, air supply in a variable mode, use of the flooring effect, use of devices for intensification of tidal flow turbulence. A set of optimal measures for obtaining the maximum economic effect is determined. A method of development and calculation of inflow mechanical ventilation systems based on the specified air distributors is proposed. The economic evaluation of the use of air distribution devices proved that the use of a two-jet air distributor makes it possible to obtain some economic effect.

Penguraian sampah organik menggunakan larva black soldiers fly (BSF) sudah banyak dilakukan oleh masyrakat perkotaan, yang menghasilkan larva untuk pakan ternak atau ikan, serta limbah yang berupa kompos. Penelitian bertujuan untuk memanfaatkan kompos limbah larva BSF sebagai pupuk organik tanaman tomat dalam sistem pertanian perkotaan. Penelitian menggunakan percobaan faktorial dengan perlakuan faktor pertama adalah pemberian kompos limbah BSF yang terdiri dari perbandingan kompos dengan tanah taman 25% berbanding 75% dan 50% berbanding dengan 50% dengan satu perlakuan kontrol, sedangkan perlakuan faktor kedua adalah pemberian pupuk kimia pabrik yaitu pupuk NPK dengan dosis 15 gr/tanaman dan 30 gr/tanaman, dengan satu perlakuan kontrol.. Variabel percobaan meliputi variabel pertumbuhan tanaman meliputi tinggi tanaman, jumlah daun, luas tapak daun, dan diameter batang, sedangkan variabel hasil meliputi berat total buah, jumlah total buah dan diameter buah. Hasil penelitian menunjukkan bahwa perlakuan kompos limbah BSF berpengaruh negatif terhadap pertumbuhan tanaman yang kemungkinan disebabkan media yang mengandung kompos kurang bisa menyimpan air siraman, namun berpengaruh positif terhadap variabel hasil yaitu perlakuan P2 yaitu kompos limbah BSF dengan substrat rumah tangga memberikan hasil tanaman paling banyak. Sedangkan untuk pupuk kimia pabrik perlakuan K2, pemberian pupuk NPK dengan dosis 30 gr per tanaman memberikan hasil yang tertinggi.
