Published: June 2023

In Indonesia, the COVID-19 pandemic is closely linked to the rise in infectious waste produced by the general public and medical professionals. Assuming that many individuals are tainted Coronavirus, the medical clinics limit can influence and how much irresistible waste produced is increment. Irresistible waste remembers for the Hazardous Toxic Waste (B3) squander classification, which contains unsafe and harmful materials that can contaminate, harm, and jeopardize the climate, wellbeing, and the endurance of living things. Ponorogo Regency, which is known as a "red zone" for the spread of COVID-19, is unavoidably affected by Hazardous Toxic (B3) waste. With the expansion in that measure of Hazardous Toxic (B3) squander, the public authority job is expected to satisfy the prudent rule and closeness standard of B3 squander the board. As the mandatory environmental affairs executor, DLHK Ponorogo, the regional government must address Hazardous Toxic (B3) waste management issues at the regional level.
Stellar Rotation and Structure of the α Persei Complex: When Does Gyrochronology Start to Work?
Authors: Boyle Andrew W. , Bouma Luke G. 
Published: June 2023

Abstract
On the pre-main sequence, the rotation rates of Sun-like stars are dictated by the interplay between the protostellar disk and the star’s contraction. At ages exceeding 100 Myr, magnetic spindown erases the initial stellar spin rate and enables rotation-based age dating (gyrochronology). The exact time at which the transition between these two regimes occurs depends on stellar mass, and has been challenging to empirically resolve due to a lack of viable calibration clusters. The α Persei open cluster (t ≈ 80 Myr, d ≈ 170 pc) may provide the needed calibrator, but recent analyses of the Gaia data have provided wildly varying views of its age and spatial extent. As such, we analyze a combination of TESS, Gaia, and LAMOST data to calibrate gyrochronology at the age of α Per and to uncover the cluster’s true morphology. By assembling a list of rotationally confirmed α Per members, we provide strong evidence that α Per is part of a larger complex of similarly aged stars. Through kinematic back-integration, we show that the most diffuse components of α Per were five times closer together 50 Myr ago. Finally, we use our stellar rotation periods to derive a relative gyrochronology age for α Per of 67% ± 12% the age of the Pleiades, which yields 86 ± 16 Myr given current knowledge. We show that by this age, stars more massive than ≈0.8 M
⊙ have converged to form a well-defined slow sequence.

Abstract
Type I X-ray bursts are rapidly brightening phenomena triggered by thermonuclear burning on the accreting layers of a neutron star (NS). The light curves represent the physical properties of NSs and the nuclear reactions on the proton-rich nuclei. The numerical treatments of the accreting NS and physics of the NS interior are not established, which shows uncertainty in modeling for observed X-ray light curves. In this study, we investigate theoretical X-ray burst models compared with burst light curves with GS 1826-24 observations. We focus on the impacts of the NS mass and radius and base heating on the NS surface using the MESA code. We find a monotonic correlation between the NS mass and the parameters of the light curve. The higher the mass, the longer the recurrence time and the greater the peak luminosity. While the larger the radius, the longer the recurrence time, the peak luminosity remains nearly constant. In the case of increasing base heating, both the recurrence time and peak luminosity decrease. We also examine the above results with a different numerical code, HERES, based on general relativity and consider the central NS. We find that the burst rate, energy, and strength are almost the same in two X-ray burst codes by adjusting the base heat parameter in MESA (the relative errors ≲5%), while the duration and rise times are significantly different between (the relative error is possibly ∼50%). The peak luminosity and the e-folding time change irregularly between two codes for different accretion rates.
Steep Balmer Decrement in Weak AGNs May Not Be Caused by Dust Extinction: Clues from Low-luminosity AGNs and Changing-look AGNs
Authors: Wu Jiancheng , Wu Qingwen , Xue Hanrui , Lei Weihua , Lyu Bing 
Published: June 2023

Abstract
The hydrogen Balmer decrement (e.g., Hα/Hβ) is widely adopted as an indicator of the internal reddening of active galactic nuclei (AGNs). This is challenged by some low-luminosity AGNs and changing-look AGNs (CLAGNs), which have steep Balmer decrement but without strong evidence for absorption. We compile a sample of normal AGNs and CLAGNs with a wider distribution of bolometric Eddington ratio (λ
Edd = L
bol/L
Edd) and find a strong negative correlation between Hα/Hβ and λ
Edd, which suggests that the Balmer decrement is also accretion-rate dependent. We further explore the Balmer decrement based on the photoionization model using the Cloudy code by considering spectral energy distribution from the accretion disk with different accretion rates (e.g., disk/corona and truncated disk at high and low Eddington ratios, respectively). Both the standard disk and truncated disk predict a negative correlation of Hα/Hβ–λ
Edd, where the relation is steeper in the case of the truncated disk. The negative correlations are also explored in two single CLAGNs. The measured negative correlation of Hα/Hβ–λ
Edd is mainly caused by the lower responsivity

in Hα relative to that in Hβ due to the larger optical depth in the former. We propose that the steep Balmer decrements in low Eddington ratio AGNs (e.g., some Seyferts 1.5–1.9 and CLAGNs) are not simply caused by absorption but mainly caused by the relatively low flux of ionizing photons.
Sparse Logistic Regression for RR Lyrae versus Binaries Classification
Authors: Trevisan Piero , Pasquato Mario , Carenini Gaia , Mekhaël Nicolas , Braga Vittorio F. , Bono Giuseppe , Abbas Mohamad 
Published: June 2023

Abstract
RR Lyrae (RRL) stars are old, low-mass, radially pulsating variable stars in their core helium burning phase. They are popular stellar tracers and primary distance indicators since they obey well-defined period–luminosity relations in the near-infrared regime. Their photometric identification is not trivial; indeed, RRL star samples can be contaminated by eclipsing binaries, especially in large data sets produced by fully automatic pipelines. Interpretable machine-learning approaches for separating eclipsing binaries from RRL stars are thus needed. Ideally, they should be able to achieve high precision in identifying RRL stars while generalizing new data from different instruments. In this paper, we train a simple logistic regression classifier on Catalina Sky Survey (CSS) light curves. It achieves a precision of 87% at 78% recall for the RRL star class on unseen CSS light curves. It generalizes on out-of-sample data (ASAS/ASAS-SN light curves) with a precision of 85% at 96% recall. We also considered a L1-regularized version of our classifier, which reaches 90% sparsity in the light-curve features with a limited trade-off in accuracy on our CSS validation set and—remarkably—also on the ASAS/ASAS-SN light-curve test set. Logistic regression is natively interpretable, and regularization allows us to point out the parts of the light curves that matter the most in classification. We thus achieved both good generalization and full interpretability.
Solar Filament Eruptions in H

Doppler Velocity

Published: June 2023

Abstract
We use observations taken with a novel solar telescope spectroheliograph to investigate the association between the early filament rise and coronal mass ejections (CMEs). The instrument allows the H
α
full line profile to be registered in each pixel of the solar disk with a time cadence of about 1 minute. We analyze observations of three eruptive filaments in 2021 and show that patrol telescope measurements of the H
α
line profile with a spectral resolution R = 40,000 can be used to detect precursors of filament eruptions with an advance of several hours and to estimate the initial acceleration of CMEs. Our limited case study also suggests that while detecting an early filament rise may serve as an indicator of a possible eruption, the filament ascent alone is not a definite sign of a CME.
Radiation Pressure Acting on the Neutral He Atoms in the Heliosphere

Published: June 2023

Abstract
Interstellar neutral helium (ISN He) is an important source of information on the physical state of the local interstellar medium. Radiation pressure acting on the neutral helium atoms in the heliosphere has always been neglected; its effect has been considered insignificant compared to gravitational force. The most advanced numerical models of ISN He take into account more and more subtle effects; therefore, it is important to check if the effect of radiation pressure is still negligible. In this paper, we use the most up-to-date version of the Warsaw Test Particle Model (WTPM) to calculate the expected helium distribution in the heliosphere and simulate the flux of the ISN He observed by the Interstellar Boundary Explorer (IBEX) and in the future by the Interstellar Mapping and Acceleration Probe (IMAP). We compare results calculated with and without radiation pressure during low and high solar activity. The results show that in the analysis of IBEX-Lo observations, the radiation pressure acting on typical helium causes flux differences at a level of 1%–4% and is comparable to the observational errors. For the more sensitive IMAP-Lo instrument, there are some regions in the considered observation configurations where radiation pressure causes potentially statistically significant changes in the calculated fluxes. The effect can be up to 9% for the indirect beam and is likely to be higher than the estimated errors. Therefore, we claim that in the future analysis of the IMAP-Lo observations, radiation pressure acting on ISN He should be considered.
Largesses, pots-de-vin et « diplomatie du vin » ? Les dons en vin sous le principat de Jean sans Peur (1404-1419)
Authors: Rameau Baptiste 
Published: June 2023

Bien de consommation mais également de prestige, le vin, notamment celui de Bourgogne, apparaît dès le principat de Philippe le Hardi comme un outil politique ; caractéristique qui se perpétue sous ses successeurs et notamment sous son petit-fils, Philippe le Bon, considéré comme « le prince des meilleurs vins de la Chrétienté ». Les dons en vin sous les ducs Valois de Bourgogne constituent donc un observatoire privilégié pour analyser la communication politique et symbolique, ainsi que les réseaux gravitant autour du prince. Centré sur Jean sans Peur (1404-1419), cet article entend, après une présentation des gratifications en lien avec les nombreux événements ponctuant le principat du deuxième duc de la maison Valois de Bourgogne, étudier cet aspect de l’économie du don en mettant l’accent sur les caractéristiques des vins et les bénéficiaires les plus récurrents dans les comptabilités bourguignonnes.
4. L’année 1797 – économie et romantisme
Authors: Vogl Joseph 
Published: June 2023

En partant de réflexions méthodologiques sur l’histoire de l’économie politique depuis le xvii e siècle, cet article cible une date marquante de l’économie financière. Alors qu’en février 1797, le projet des assignats français doit être reconnu comme un échec, au même moment, le Bank Restriction Act anglais, qui interdit la convertibilité des billets de banque en métal précieux, est perçu comme un tournant historique et un défi pour l’analyse économique. Les romantiques allemands, en particulier, voient dans l’expérience anglaise un projet à l’avenir prometteur – à la différence de la monnaie révolutionnaire française –, dans lequel le crédit public en circulation et les nouvelles théories du crédit deviennent des modèles pour une modernisation des concepts de systèmes économiques, politiques et sociaux.
Formateur/maître d’apprentissage : une rivalité féconde ?
Authors: Léonard Érika 
Published: June 2023

Formateur et maître d’apprentissage sont les deux principaux référents de l’apprenti. Tous deux occupent pourtant un territoire singulier et circonscrit. Au premier incombe la formation en vue de l’obtention du diplôme, dans l’espace clos du centre de formation. Au second revient la confrontation à l’activité professionnelle réelle, hors les murs, comme dans la vraie vie. Tous deux ont pourtant une mission commune : assurer la montée en compétences de « leur » apprenti, même s’ils le confrontent à des pratiques et des discours parfois contradictoires. Sur fond de rivalité réelle ou fantasmée, ils offrent néanmoins à l’apprenti la possibilité de se positionner et de tracer sa voie. L’article montre la fécondité de cette rivalité.
Tracer l’utilisation de recettes et/ou d’ingrédients européens dans les objets émaillés : stratégie et premiers résultats
Authors: Colomban Philippe 
Published: June 2023

Différentes recettes d’émaillage peuvent donner un même résultat visuel. Identifier les agents colorants et la matrice silicatée des émaux est nécessaire pour comparer les techniques de production des porcelaines et objets métalliques, émaillés, produits spécifiquement pour l’Empereur et sa cour. L’analyse doit être non-invasive et conduite dans les lieux de conservation des objets. Notre expérience de vingt ans d’étude non-invasive des verres, céramiques et objets métalliques anciens a conduit à focaliser les analyses sur les couleurs bleu, blanc, jaune, vert et rouge/rose en utilisant deux techniques d’analyse mobile : la fluorescence des rayons X et la micro-spectroscopie Raman. Ces méthodes complémentaires identifient les éléments (ou les phases) colorants/opacifiants (jaune et vert : pyrochlore à base de plomb, d’étain ou d’antimoine ; rose : nanoparticules d’or ; blanc : arséniates de plomb-calcium ; bleu : cobalt, asiatique ou européen ; rouge : hématite ou nanoparticules de cuivre). Le but est de comparer les dates d’innovation en Europe et en Chine.
Writing and Drawing Inventions: Patents and Technology in France and the United States (18th-19th centuries)
Authors: Baudry Jérôme 
Published: June 2023

Dans les régimes de brevets d’invention qui se mettent en place au xviiie siècle, d’abord en Angleterre puis aux États-Unis et en France, la description (par le texte, l’image, le modèle, l’échantillon) occupe un rôle central. Elle permet d’opérationnaliser l’idée de contrat au fondement du brevet : protection contre divulgation. D’année en année, les « specifications » anglaises et américaines et les « mémoires descriptifs et explicatifs » français viennent alimenter une immense littérature technologique, dont la particularité est d’être (en principe) écrite par les inventeurs eux-mêmes. Cet article explore les styles et les techniques de représentation mis en œuvre dans les brevets d’invention, principalement en France, mais aussi en comparaison avec les États-Unis. L’étude de la diversité et de l’évolution de ces représentations dessine en creux tout à la fois une histoire renouvelée des brevets et de leurs usages, et une histoire de la pensée de la technique au xixe siècle.

Abstract
Although several immunomodulatory drugs are available for multiple sclerosis (MS), most present significant side effects with long-term use. Therefore, delineation of nontoxic drugs for MS is an important area of research. β-Hydroxy β-methylbutyrate (HMB) is accessible in local GNC stores as a muscle-building supplement in humans. This study underlines the importance of HMB in suppressing clinical symptoms of experimental autoimmune encephalomyelitis (EAE) in mice, an animal model of MS. Dose-dependent study shows that oral HMB at a dose of 1 mg/kg body weight/d or higher significantly suppresses clinical symptoms of EAE in mice. Accordingly, orally administered HMB attenuated perivascular cuffing, preserved the integrity of the blood–brain barrier and blood–spinal cord barrier, inhibited inflammation, maintained the expression of myelin genes, and blocked demyelination in the spinal cord of EAE mice. From the immunomodulatory side, HMB protected regulatory T cells and suppressed Th1 and Th17 biasness. Using peroxisome proliferator-activated receptor (PPAR)α−/− and PPARβ−/− mice, we observed that HMB required PPARβ, but not PPARα, to exhibit immunomodulation and suppress EAE. Interestingly, HMB reduced the production of NO via PPARβ to protect regulatory T cells. These results describe a novel anti-autoimmune property of HMB that may be beneficial in the treatment of MS and other autoimmune disorders.

Abstract
The human lung carries a unique microbiome adapted to the air-filled, mucous-lined environment, the presence of which requires an immune system capable of recognizing harmful populations while preventing reactions toward commensals. B cells in the lung play a key role in pulmonary immunity, generating Ag-specific Abs, as well as cytokine secretion for immune activation and regulation. In this study, we compared B cell subsets in human lungs versus circulating cells by analyzing patient-paired lung and blood samples. We found a significantly smaller pool of CD19+, CD20+ B cells in the lung relative to the blood. CD27+, IgD−, class-switched memory B cells (Bmems) composed a larger proportion of the pool of pulmonary B cells. The residency marker CD69 was also significantly higher in the lung. We also sequenced the Ig V region genes (IgVRGs) of class-switched Bmems that do, or do not, express CD69. We observed the IgVRGs of pulmonary Bmems to be as heavily mutated from the unmutated common ancestor as those in circulation. Furthermore, we found progenies within a quasi-clone can gain or lose CD69 expression, regardless of whether the parent clone expressed the residency marker. Overall, our results show that despite its vascularized nature, human lungs carry a unique proportion of B cell subsets. The IgVRGs of pulmonary Bmems are as diverse as those in blood, and progenies of Bmems retain the ability to gain or lose residency.

Abstract
“Adaptive” NK cells, characterized by FcRγ deficiency and enhanced responsiveness to Ab-bound, virus-infected cells, have been found in certain hCMV-seropositive individuals. Because humans are exposed to numerous microbes and environmental agents, specific relationships between hCMV and FcRγ-deficient NK cells (also known as g-NK cells) have been challenging to define. Here, we show that a subgroup of rhesus CMV (RhCMV)-seropositive macaques possesses FcRγ-deficient NK cells that stably persist and display a phenotype resembling human FcRγ-deficient NK cells. Moreover, these macaque NK cells resembled human FcRγ-deficient NK cells with respect to functional characteristics, including enhanced responsiveness to RhCMV-infected target in an Ab-dependent manner and hyporesponsiveness to tumor and cytokine stimulation. These cells were not detected in specific pathogen-free (SPF) macaques free of RhCMV and six other viruses; however, experimental infection of SPF animals with RhCMV strain UCD59, but not RhCMV strain 68-1 or SIV, led to induction of FcRγ-deficient NK cells. In non-SPF macaques, coinfection by RhCMV with other common viruses was associated with higher frequencies of FcRγ-deficient NK cells. These results support a causal role for specific CMV strain(s) in the induction of FcRγ-deficient NK cells and suggest that coinfection by other viruses further expands this memory-like NK cell pool.
A Single-Blind Randomized Control Trial on the Effectiveness of Adjunct Cognitive Stimulation Therapy on Cognitive Outcomes in Dementia
Authors: Bhowmik Soumya , Chandra Mina , Anand Kuljeet , Dahuja Shrishti 
Published: June 2023

Background:
Dementia is characterized by neurocognitive decline which interferes with daily function and independence. Cognitive stimulation therapy (CST) is an evidence-based cognitive psychosocial intervention for people with dementia.

Materials and Methods:
A prospective interventional study of single-blind RCT design conducted in the Department of Neurology at ABVIMS and Dr RML Hospital amongst patients with DSM-V major neurocognitive disorder aged more than 50 years. Participants were randomized to CST and control groups using a block-randomized design. The control group participants received treatment as usual while the CST group delivered 45-min virtual group CST sessions for a total of 14 sessions over seven weeks. All participants in both groups were assessed at baseline and eight weeks using the Montreal Cognitive Assessment Scale (MoCA), Alzheimer’s Disease Assessment Scale Cognitive Subscale (ADAS-Cog), neuropsychiatric inventory, instrumental activities of daily living, and Zarit Burden Interview for Caregiver Burden (ZBI) by a rater blind to group randomization.

Results:
Total MoCA scores improved significantly in the CST group, compared to the control group which showed a statistically significant decrease. The mean total ADAS-Cog score in the CST group improved significantly compared to controls. The Lawton Instrumental Activities of Daily Living Scale showed a statistically significant change in the control group compared to the intervention group. From the comparison of the mean total neuropsychiatric inventory scale, it was observed that there was a statistically significant decrease in the severity of Behavioural and Psychological Symptoms of Dementia (BPSD) symptoms in the CST group. The mean total ZBI score decreased significantly in the CST group favoring less caregiver burden.

Conclusion:
This study proved that CST has a significant impact on cognitive outcomes in dementia and it also proved its effectiveness in controlling the BPSD outcomes and caregiver burden in dementia.
