Beyond the denial of death: death meditation increases a sense of connectedness and appreciation of life
Authors: Das Enny , Fransen Marieke L. , Oliver Mary Beth 
Published: November 2024

IntroductionThe pervasive denial of death in modern society has created an unbalanced relationship with death that gets in the way of living a full life. To address this problem, the Lancet Commission on the Value of Death recently proposed principles of a healthier scenario for the future. In this ‘realistic utopia’, death is recognized as having value, and conversations about death and dying have become common. The present research examined if art could help to decrease death denial and increase life appreciation.MethodsAn art installation invited visitors to confront thoughts of their own death in a guided meditation by visualizing the decay of their own dead body. Visitors’ responses were compared to those of a standard death reflection group and a neutral control group (N=229) at two time points. Feelings of being moved, connectedness to a higher power, and life appreciation were assessed immediately (T1); death reflection and life appreciation were assessed two weeks later (T2) (N=105).ResultsAt T1, the art installation induced higher levels of being moved and connectedness to a higher power than the two control groups. At T2, the art installation induced more lingering reflection than the two control groups. Lingering reflection, in turn, increased appreciation of life.DiscussionWe show that art can be harnessed to promote a more balanced relationship with death, and greater appreciation of life. The art installation provided individuals with concrete, and more encompassing simulations of what death could be like. By placing death in this bigger perspective, the art installation encouraged conscious death reflection. Such a connected perspective is often lacking, but direly needed, in healthcare and in larger society.

ObjectivesTo examine trends in socioeconomic inequality in adolescent health over three decades, across fifteen health indicators: overweight, underweight, headache, stomachache, backpain, emotional symptoms, difficulties falling asleep, loneliness, low life satisfaction, low self-rated heath, smoking, drunkenness, physical inactivity, low vegetable intake, and inadequate toothbrushing.MethodsThe Health Behaviour in School-aged Children (HBSC) study in Denmark included nine identical surveys of 11–15-year-olds from 1991 to 2022, n = 35,423. For each health indicator, we measured absolute and relative socioeconomic inequality by prevalence differences and odds ratios between low and high socioeconomic groups.ResultsThere was socioeconomic inequality in thirteen health indicators, e.g., the OR (95% CI) for overweight in low vs. high socioeconomic groups was 2.22 (1.95–2.49). This social inequality persisted across health indicators throughout the study period with two deviations: Underweight was not associated with socioeconomic background and drunkenness was persistently most prevalent in higher socioeconomic groups.ConclusionThe political efforts to reduce socioeconomic inequality in health seems to have failed. It is important to improve monitoring of adolescent health and implement improved policies to tackle socioeconomic inequality in adolescent health.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with Acanthamoeba strains detected in Poland, were evaluated in this study. Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy. In vitro techniques were applied for detection of bacteria and fungi, and corneal isolates cultured under axenic condition using BSC medium—for detection of Acanthamoeba spp.; molecular techniques were applied for amoeba species identification. Results: Most etiologically complicated keratitis cases, detected in ~84% of incidents, was due to exposure of contact lenses to tap water or pool water; trophozoites and cysts of Acanthamoeba, concomitant bacteriae, e.g., Pseudomonas aeruginosa, fungi and microfilariae were identified in contact lens users. Conclusions: In samples from contact lens wearers where microbial keratitis is identified along with some connection with the patient’s exposure to contaminated water environments, a risk of Acanthamoeba spp. infections should be considered. Understanding the complicated relationship between Acanthamoeba spp., co-occurring pathogens including associated endosymbionts is needed. In vivo confocal microscopy and in vitro cultivation were necessary to identify potentially contagious concomitant factors affecting the complex course of the keratitis.
Нелинейная рекуррентная фильтрация в задаче оценивания параметров сигнала M-QAM на фоне логнормальной помехи
Authors: Н.Е. Поборчая , С.А. Жарких 
Published: November 2024

В работе рассматривается алгоритм нелинейной фильтрации с первым приближением по Тейлору для оценивания амплитуды, сдвига частоты и фазы сигнала M-QAM с известными информационными символами, наблюдаемого на фоне смеси белого гауссовского шума и логнормальной помехи. Также в модели сигнала присутствует фазовый шум, который вносит свой вклад в негауссовость помех. Алгоритм получен с помощью модифицированного метода наименьших квадратов в форме функционала Тихонова и не использует никакой информации о законах распределения случайных процессов, входящих в уравнение наблюдений. Проведен вычислительный эксперимент, который показал работоспособность данного подхода при наличии негауссовского мешающего воздействия и возможность достичь удовлетворительной точности оценивания параметров сигнала 64-QAM при правильном выборе параметров алгоритма и объема выборки сигнала. Исследована точность оценивания параметров сигнала алгоритмом нелинейной фильтрации при наличии логнормальной помехи и при ее отсутствии.
This paper introduces the nonlinear filtering algorithm with the first Taylor’s approximation for estimating the amplitude, frequency shift, and phase of the M-QAM signal with known information symbols observed against the background of the mixture of white Gaussian noise and lognormal interfering signal. There is also phase noise present in the signal model, which contributes to the non-Gaussian interfering signal. The algorithm is obtained using the modified mean square method in the form of Tikhonov’s functional and does not use any information about the distribution law of random processes included in the watch equation. The computational experiment was conducted that demonstrated the efficiency of this approach in the presence of a non-Gaussian interference effect and the ability to achieve a satisfactory level of estimation accuracy for the 64-QAM signal with the correct selection of the algorithm’s parameters and the sample size of the signal. The accuracy of signal parameters’ estimation by a nonlinear filtering algorithm has been investigated with lognormal interference and without it.

Abstract
The effects of SiO2 cap annealing at 800 °C on Ga-polar n-type and p-type GaN (0001) surfaces were compared by X-ray photoelectron spectroscopy. We found that the native oxide thickness at the GaN surfaces is usually at the monolayer level regardless of the process step, except immediately after SiO2 cap annealing for p-type GaN. Furthermore, for both conduction types, the surface Fermi level is located between the conduction band edge and the charge neutrality level regardless of the process step, which indicated that donor-like defects existed in the vicinity of the p-type GaN surfaces.

This study aims to reveal how Ma'had Aly formulated various strategies to strengthen religious moderation among his students. Ma'had Aly is a pesantren higher education that is prepared to produce pesantren cadres. The focus of his education was the study of the yellow book and the texts of classical Islamic scholars. In addition to studying, Ma'had Aly students have the task of helping kyai guide the daily activities of students at Islamic boarding schools. Their high intensity with students can have implications for the religious views of students in Islamic boarding schools so that students are required to have a moderate religious understanding. This research uses qualitative methods in the form of field research by focusing data mining on curriculum, extracurricular and literacy sources of Ma'had Aly. The data was then measured based on four concepts of religious moderation by the Ministry of Religious Affairs of the Republic of Indonesia and analyzed using descriptive analysis. The results showed that Ma'had Aly Attaqwa KH. Noer Alie can be categorized as moderate by making national commitment as the main strategy to strengthen religious moderation. The results also show that the practice of Pancasila, love of the Republic of Indonesia and the practice of patriotic values have been instilled from the beginning by KH. Noer Alie, the founder of Ma'had Aly Attaqwa, was also a freedom fighter and was awarded as a national hero in Indonesia.

Toward a Unified Injection Model of Short-lived Radioisotopes in N-body Simulations of Star-forming Regions
Authors: Eatson Joseph W. , Parker Richard J. , Lichtenberg Tim 
Published: November 2024

Abstract
Recent research provides compelling evidence that the decay of short-lived radioisotopes (SLRs), such as 26Al, provided the bulk of energy for heating and desiccation of volatile-rich planetesimals in the early solar system. However, it remains unclear whether the early solar system was highly enriched relative to other planetary systems with similar formation characteristics. While the solar system possesses an elevated level of SLR enrichment compared to the interstellar medium, determining SLR enrichment of individual protoplanetary disks observationally has not been performed and is markedly more difficult. We use N-body simulations to estimate enrichment of SLRs in star-forming regions through two likely important SLR sources: stellar winds from massive stars and supernovae (SNae). We vary the number of stars and the radii of the star-forming regions and implement two models of stellar-wind SLR propagation for the radioisotopes 26Al and 60Fe. We find that for 26Al enrichment the solar system is at the upper end of the expected distribution, while for the more SNae-dependent isotope 60Fe we find that the solar system is comparatively very highly enriched. Furthermore, combined with our previous research, these results suggest that the statistical role of 26Al-driven desiccation on exoplanet bulk composition may be underestimated in typical interpretations of the low-mass exoplanet census, and that 60Fe is even less influential as a source of heating than previously assumed.
Stellar Pulsation and Evolution: A Combined Theoretical Renewal and Updated Models (SPECTRUM). I. Updating Radiative Opacities for Pulsation Models of Classical Cepheid and RR-Lyrae

Published: November 2024

Abstract
Pulsating stars are universally recognized as precise distance indicators and tracers of stellar populations. Their variability, combined with well-defined relationships between pulsation properties and intrinsic evolutionary parameters such as luminosity, mass, and age, makes them essential for understanding galactic evolution and retrieving star formation histories. Therefore, accurate modeling of pulsating stars is crucial for using them as standard candles and stellar population tracers. This is the first paper in the “Stellar Pulsation and Evolution: a Combined Theoretical Renewal and Updated Models” project, which aims to present an update of Stellingwerf’s hydrodynamical pulsation code, by adopting the latest radiative opacity tables commonly used in stellar evolution community. We assess the impact of this update on pulsation properties, such as periods, instability strip topology, and light-curve shapes, as well as on period–Wesenheit and period–luminosity relations for Classical Cepheids and RR Lyrae stars, comparing the results with those derived using older opacity data. Our results indicate that the opacity update introduces only minor changes: instability strip boundary locations shift by no more than 100 K in effective temperature, and pulsation periods vary within 1σ compared to previous evaluations. Light curves exhibit slight differences in shape and amplitude. Consequently, the theoretical calibration of the Cepheid- or RRL-based extragalactic distance scale remains largely unaffected by the opacity changes. However, achieving consistency in opacity tables between stellar evolution and pulsation codes is a significant step toward a homogeneous and self-consistent stellar evolution and pulsation framework.
An Extreme Radio Fluctuation of Pulsar B1929+10

Published: November 2024

Abstract
We report the detection of an extreme flux decrease accompanied by clear dispersion measure (DM) and rotation measure (RM) variations for pulsar B1929+10 during the 110 minute radio observation with the Five-hundred-meter Aperture Spherical radio Telescope. The radio flux decreases by 2–3 orders of magnitude within a rapid timescale of about 20 minutes. Meanwhile, the variations of DM and RM are approximately 0.05 pc cm−3 and 0.7 rad m−2, respectively. Frequency-dependent analysis of DM indicates an extremely weak chromatic DM feature, which does not notably affect the radiative behavior detected. Moreover, the pulsar timing analysis shows an additional time delay from 100 μs to 400 μs in the event. These results are speculated to be due to the eclipse and bend for the radio emission of pulsar B1929+10 by a highly dense outflow from the pulsar. This not only impacts the intrinsic radio emission feature but also affects the pulsar timing behavior. Nevertheless, a plasma lens effect lasting around 20 minutes could also be responsible for the event.
Composition and Provenance of the Chang′e-6 Lunar Samples: Insights from the Simulation of the Impact Gardening Process

Abstract
In 2024 June, China’s Chang′e-6 (CE-6) mission successfully returned 1935.3 grams of samples from the lunar farside for the first time. The origin and composition of the unique samples could offer valuable insights into fundamental questions on the Moon’s evolutional history. Besides the local materials of mare basalts, a certain quantity of foreign ejecta materials are expected in the samples, while their percentage was mostly overestimated since the influence of impact gardening was not fully considered. In this study, we model the impact gardening process surrounding the CE-6 landing site by numerical simulations. Our simulations show that impact gardening played a key role in overturning the local materials and diluting the foreign ones in the top-meters-deep layer at the landing site. About 90% of the CE-6 drilled samples, which were sampled within the top ∼1 m deep layer, are predicted to be the local intermediate-Ti mare basalts originating in the deeper area of 1–60 m, and the underlying low-Ti basalts may make up <1%. The foreign materials in the CE-6 drilled samples likely constitute a minor portion, with an abundance of ∼3.0%. As the primary contributor (∼2.1%) of foreign materials, Chaffee S ejecta may contain lunar mantle materials excavated by the South Pole–Aitken basin.

Published: November 2024

Abstract
Misaligned circumbinary disks will produce dust traffic jams during alignment or antialignment to the binary orbital plane. We conduct a hydrodynamical simulation of an initially misaligned circumbinary disk undergoing polar alignment with multiple dust species. Due to differential precession between the gas and dust components, multiple dust traffic jams are produced within the disk during polar alignment. The radial locations of the dust traffic jams depend on the Stokes number of the grains, which depends on grain size. We compute the dust temperature structure using postprocessing radiative transfer to produce continuum images at centimeter wavelengths. Multiple distinct rings emerge in the continuum images, corresponding to the dust traffic jams. The angular resolution of upcoming observations from the Square Kilometre Array and the next-generation Very Large Array will be sufficient to detect centimeter-sized grains in protoplanetary disks and resolve the widths of dust traffic jams. Therefore, dust traffic jams resulting from the differential precession of gas and dust in misaligned circumbinary disks will be a prime target for more extended wavelength observations.
