Authors: Chiang Chun-Cheng , Yeh Hsuan , Shiu Ruei-Feng , Chin Wei-Chun , Yen Tzung-Hai
Published: March 2024

With continuous population and economic growth in the 21st century, plastic pollution is a major global issue. However, the health concern of microplastics/ nanoplastics (MPs/NPs) decomposed from plastic wastes has drawn public attention only in the recent decade. This article summarizes recent works dedicated to understanding the impact of MPs/NPs on the liver-the largest digestive organ, which is one of the primary routes that MPs/NPs enter human bodies. The interrelated mechanisms including oxidative stress, hepatocyte energy re-distribution, cell death and autophagy, as well as immune responses and inflammation, were also featured. In addition, the disturbance of microbiome and gut-liver axis, and the association with clinical diseases such as metabolic dysfunction-associated fatty liver disease, steatohepatitis, liver fibrosis, and cirrhosis were briefly discussed. Finally, we discussed potential directions in regard to this trending topic, highlighted current challenges in research, and proposed possible solutions.

Published: March 2024

BACKGROUND

Traditional esophagogastroduodenoscopy (EGD), an invasive examination method, can cause discomfort and pain in patients. In contrast, magnetically controlled capsule endoscopy (MCE), a noninvasive method, is being applied for the detection of stomach and small intestinal diseases, but its application in treating esophageal diseases is not widespread.

AIM

To evaluate the safety and efficacy of detachable string MCE (ds-MCE) for the diagnosis of esophageal diseases.

METHODS

Fifty patients who had been diagnosed with esophageal diseases were prospectively recruited for this clinical study and underwent ds-MCE and conventional EGD. The primary endpoints included the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of ds-MCE for patients with esophageal diseases. The secondary endpoints consisted of visualizing the esophageal and dentate lines, as well as the subjects' tolerance of the procedure.

RESULTS

Using EGD as the gold standard, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of ds-MCE for esophageal disease detection were 85.71%, 86.21%, 81.82%, 89.29%, and 86%, respectively. ds-MCE was more comfortable and convenient than EGD was, with 80% of patients feeling that ds-MCE examination was very comfortable or comfortable and 50% of patients believing that detachable string v examination was very convenient.

CONCLUSION

This study revealed that ds-MCE has the same diagnostic effects as traditional EGD for esophageal diseases and is more comfortable and convenient than EGD, providing a novel noninvasive method for treating esophageal diseases.
Treatment of Helicobacter pylori with potassium competitive acid blockers: A systematic review and meta-analysis
Authors: Kanu Joseph Edwin , Soldera Jonathan
Published: March 2024

BACKGROUND

Helicobacter pylori (H. pylori ) infects over half the global population, causing gastrointestinal diseases like dyspepsia, gastritis, duodenitis, peptic ulcers, G-MALT lymphoma, and gastric adenocarcinoma. Eradicating H. pylori is crucial for treating and preventing these conditions. While conventional proton pump inhibitor (PPI)-based triple therapy is effective, there’s growing interest in longer acid suppression therapies. Potassium competitive acid blocker (P-CAB) triple and dual therapy are new regimens for H. pylori eradication. Initially used in Asian populations, vonoprazan (VPZ) has been recently Food and Drug Administration-approved for H. pylori eradication.

AIM

To assess the efficacy of regimens containing P-CABs in eradicating H. pylori infection.

METHODS

This study, following PRISMA 2020 guidelines, conducted a systematic review and meta-analysis by searching MEDLINE and Scopus libraries for randomized clinical trials (RCTs) or observational studies with the following command: [(“Helicobacter pylori ” OR “H pylori”) AND (“Treatment” OR “Therapy” OR “Eradication”) AND (“Vonaprazan” OR “Potassium-Competitive Acid Blocker” OR “P-CAB” OR “PCAB” OR “Revaprazan” OR “Linaprazan” OR “Soraprazan” OR “Tegoprazan”)]. Studies comparing the efficacy of P-CABs-based treatment to classical PPIs in eradicating H. pylori were included. Exclusion criteria included case reports, case series, unpublished trials, or conference abstracts. Data variables encompassed age, diagnosis method, sample sizes, study duration, intervention and control, and H. pylori eradication method were gathered by two independent reviewers. Meta-analysis was performed in R software, and forest plots were generated.

RESULTS

A total of 256 references were initially retrieved through the search command. Ultimately, fifteen studies (7 RCTs, 7 retrospective observational studies, and 1 comparative unique study) were included, comparing P-CAB triple therapy to PPI triple therapy. The intention-to-treat analysis involved 8049 patients, with 4471 in the P-CAB intervention group and 3578 in the PPI control group across these studies. The analysis revealed a significant difference in H. pylori eradication between VPZ triple therapy and PPI triple therapy in both RCTs and observational studies [risk ratio (RR) = 1.17, 95% confidence interval (CI): 1.11-1.22, P < 0.0001] and (RR = 1.13, 95%CI: 1.09-1.17, P < 0.0001], respectively. However, no significant difference was found between tegoprazan (TPZ) triple therapy and PPI triple therapy in both RCTs and observational studies (RR = 1.04, 95%CI: 0.93-1.16, P = 0.5) and (RR = 1.03, 95%CI: 0.97-1.10, P = 0.3), respectively.

CONCLUSION

VPZ-based triple therapy outperformed conventional PPI-based triple therapy in eradicating H. pylori , positioning it as a highly effective first-line regimen. Additionally, TPZ-based triple therapy was non-inferior to classical PPI triple therapy.
Effect of rabies vaccination on population densities of Vulpes vulpes in south-western Poland (Carnivora: Canidae)
Authors: Kopij Grzegorz
Published: March 2024

Despite intensive studies on the red fox (Vulpes vulpes), little is known about current spatial and temporal dynamics of red fox populations. This study analysed the spatial and temporal changes of red fox populations in the south-western part of Poland in relation to main factors shaping the changes, above all the rabies vaccination. After a long period of low population density depressed by rabies, a rapid increase took place in the last decade of the 20th century, as a consequence of vaccination applied on a wide scale throughout SW Poland. The populations reached the highest levels ever in the two first decades of the 21st century, they stabilized, and at the end of the second decade they begun to decline. In 2001–2020, the crude population density ranged from 0.6 to 12 red foxes per 100 ha. It was highest in the regions with the lowest afforestation (6.7–12 ind./100 ha), whereas in the regions with the highest afforestation it was the lowest (0.6–0.8 ind./100 ha). The ecological consequences of these changes in the fox population densities are paralleled with changes in population densities of many prey species and fox’s competitors.

Examining Pakistan’s Relationship with Religious Minorities: A Case Study of the Christian Community
Authors: Ayra Indrias Patras
Published: March 2024

The constitution of Pakistan asserts the principle of equal citizenship regardless of religious distinctions and commits to safeguarding minority groups. The subject of religious minorities in Pakistan is framed within the ambit of socio-political and historical trajectories that substantiate their marginalized status. Nevertheless, the dynamics of the relationship between religious minorities and the state, particularly concerning equal citizenship, have not been extensively examined. Based on 26 comprehensive interviews with members of the Lahore Christian community, this study aims to elucidate the meaning of citizenship understood by people situated at the margins of society. While drawing inferences from the theory of intersectionality, which underscores how various forms of oppression can intersect and exacerbate disadvantage and discrimination, the study suggests that Christian communities occupy a distinct place in the spectrum of citizenship. This positioning is attributed to their profound sense of distinctiveness, stemming from their unique religious identity.

Published: March 2024

Good government is a government that is responsive, free from corruption, collusion and nepotism (Korupsi, Kolusi dan Nepotisme/KKN) and has good performance. Good governance can also be assessed from accountability, transparency and participation in every work result. Government Accounting Standards (Standar Akuntansi Pemerintahan/SAP) are a set of technical guidelines that regulate accounting principles, methods, procedures and practices that must be applied by government entities in preparing financial reports. Good financial reports have the following characteristics relevant, reliable, comparable, understandable. This research was conducted at the Suka Makmur social service, this research used descriptive qualitative methods. The location of the research was the Suka Makmur social service. The data used in this research is primary data obtained from interviews and observations. The data analysis technique used is the Miles Huberman model, namely data reduction, data presentation and drawing conclusions. The results of this research state that the implementation of government accounting standards in Suka Makmur social services makes the quality of financial reports better.
Contrast preservation and other segmental effects in the formation of Xochistlahuaca Amuzgo plurals
Authors: Dobui Bien , Faust Noam , Apóstol Polanco Jair
Published: March 2024

In Amuzgo (Eastern Otomanguean), the formation of nominal plurals exhibits many realizations, ranging from the simple addition of a nasal prefix, to additional initial consonant fortition, initial consonant deletion, and sometimes also the replacement of the prefixal nasal by a lateral. In this paper, we argue that all of these changes follow from two main principles: (1) The underlying contrast between the two pairs of phonemes characterized by a delayed release – the [+anterior] /s, ʦ/ and the [‑anterior] /ʃ, ʧ/ – must be maintained; and (2) /s, ʃ/ cannot be faithfully realized after [n]. These principles, in interaction with other considerations, lead to an establishment of a push chain (/s/→/ʦ/→/t/) among [+anterior] consonants and to a case of saltation (/ʧ/→/ʧ/; /ʃ/→/k/) among [-anterior] consonants.

O TRAÇO IRÔNICO DO LIRISMO DE BORGES EM O ALEPH, E A IRONIA EXISTENCIAL DE QUIROGA EM A GALINHA DEGOLADA
Authors: MICALI D.L.C.
Published: March 2024

O conto O Aleph (1949), de Jorge Luis Borges, revela-se uma narrativa realistaentremeada de estrofes líricas, cujo enredo contém um elemento fantástico, pois admite a existência de uma pequena esfera refletora: o aleph – objeto que reflete como espelho tudo o que existe no universo. Como fenômeno de existência duvidosa no mundo diegético, a aparição do aleph – o “microcosmo dos alquimistas e cabalistas”, como diz o narrador-autor –contém em si algo de irônico, considerando que a ambiguidade é um atributo da ironia. Istoenquadra essa narrativa no realismo fantástico, gênero também praticado por outros autores latino-americanos, a exemplo de Horácio Quiroga no conto A galinha degolada (1917), em que a ironia existencial transforma a vida de uma jovem família numa sucessão de tragédias.O destino prega uma peça no casal protagonista ao presenteá-los com quatro filhos que, sucessivamente, se tornam idiotas após completarem dezoito meses de vida. No seu breve e incrível relato, o narrador-autor questiona profunda e cruamente a realidade: o quê, nesse real, seria de fato verdadeiro ou possível? Esta análise dos dois contos supracitados, à luz do realismo fantástico (ou mágico) da literatura, focaliza o caráter lírico e/ou irônico da ficcionalidade de cada autor.

Este trabalho aborda o fenômeno da intertextualidade enquanto recurso para a deflagração de humor em memes verbo-visuais. A partir disso, objetivamos (a) identificar categorias de intertextualidade presentes em exemplares de memes verbo-visuais e (b) analisar o modo como recurso é usado para deflagar o humor nos memes selecionados. Para tanto, construímos um estudo qualitativo, descritivo e explicativo (Gerhardt; Silveira, 2009) em que selecionamos exemplares prototípicos de memes verbo-visuais que circulam nas mídias digitais. Os memes coletados foram analisados à luz de estudiosos como Piègay-Gross (1996), Koch, Bentes e Cavalcante (2008), Koch (2016), Possenti (2018) Travaglia (1989, 2015). Verificamos a presença de diferentes categorias de intertextualidade por copresença, a exemplo da citação e referência. A partir disso, concluímos que a intertextualidade contribui para a construção do humor à medida que proporciona o diálogo entre textos produzidos previamente, gerando situações cômicas em que se pode verificar o intuito de fazer rir e, ao mesmo tempo, a construção de críticas sociais.

Published: March 2024

A change in combustion concepts from conventional isobaric to constant volume combustion (CVC) has several advantages. Pulse detonation combustion (PDC) operates on CVC, increasing the engine's thermodynamic efficiency significantly. Little research has been conducted on pollutant emissions from pulse detonation engines (PDE). Because PDE burns at a higher temperature, it emits more NOx. The formation of NOx is investigated in this paper using the computational fluid dynamics (CFD) method. For hydrogen fuel, a model is built by varying pressure, temperature, spark size, and geometry. The SST K- Omega model is used with transient conditions. EINOx was calculated using CFD analysis for 12 cm and 20 cm tubes. The results were encouraging. A 12 cm tube produced 200 g/kg of fuel EINOx, while a 20 cm tube produced 250 g/kg of fuel EINOx. The computed results are consistent with previous literature.

Published: March 2024

The gravitational water vortex turbine (GWVT) is a promising solution to exploit the potential of low-head hydro energy. Previous research has shown that a 3D runner performs better than a runner with a flat blade and a 2D curved blade. This research investigates the performance of a conical gravitational water vortex turbine (CGWVT) with a 3D runner using numerical simulations and experiments. The numerical simulations were carried out with Fluent V 6.1, a 2-phase transient incompressible solver, at various torque loads. Furthermore, experiments were conducted to validate the numerical simulations by varying the torque load and water flow rate. The experiment revealed that the maximum power was achieved at a rotational speed of around 100 to 110 rpm. The maximum efficiency was 0.28 at a flow rate of 0.00477 m³/s. The developed simulation closely matched the experimental results, making it useful for design and prediction for further development.

Published: March 2024

Many electronic gadgets now require more power as a result of technological advancements, and to prolong their lifespan, they must all be kept thermally stable. To prevent electronic equipment from operating above their safe operating temperature, numerous techniques are used. Due to its low cost and dependable manner of cooling, the naturally cooled heat sink is the most used technology. The goal of the current research is to improve the thermal efficiency of less dense heat sinks by modifying their design and orientation. The aluminium heat sink utilized for the experimental and numerical investigation has the following dimensions: length 120 mm, width 100 mm, thickness 2 mm, height 40 mm, and channel width 12 mm. The cartridge-type heater received heat input ranging from 25 W, 50 W, 75 W, and 100 w. Under natural convection, the orientation was changed to 0°, 15°, 30°, 45°, 60°, and 90°. By increasing the orientation angle of the heat sink from 00 (horizontal position) for all the heat input, the Nusselt number and rate of heat transfer increases. Due to changes in the flow pattern, the vertical orientation of the heat sink was found to be transferring heat more quickly than other orientations. According to the study, plate-fin heat sinks with circular in-line notches perform thermally better than those without any notches.

Published: March 2024

Research has been conducted on the study of the velocity and thermal slips' impact on the Williamson fluid flow above a stretching sheet in the existence of an inclined magnetic field and Radiation. By applying the proper similarity conversions, the governing equations (PDEs) are reduced to a set of non-linear ODEs, and a numerical solution is produced by using MATLAB in-built solver bvp4c package. The impacts of the dimensionless characteristics on the flow patterns are analyzed visually, and the values of the friction, Nusselt, and mass transfer quantities are tabulated to exemplify how the various physical factors have an influence. We noted that the velocity profile enhances the rising estimations of velocity slip and the temperature profile increases with Q increase.
Colours for Mourning. Ceramic Tiles in Spanish Cemeteries
Authors: Román Caro Mª Elena
Published: March 2024

La imagen que de los cementerios tenemos a veces es gris. El gris de la piedra, del cemento, del hormigón, de los caminos… pero no siempre fue así. Hubo un tiempo en el que, en algunos cementerios, brillaban los colores, los que procedían de la multitud de azulejos cerámicos que cubrían los nichos y algunas de las sepulturas a ras de suelo del camposanto. El azulejo, menospreciado en su humildad, fue durante decenas de años, el material escogido por las gentes para endulzar la muerte, para dar una nota de color al lugar donde se deposita el recuerdo. El presente estudio pretende realizar una caracterización de los tipos de azulejos que se usaron en los cementerios españoles por medio de lo que se practicó en una parte del territorio valenciano: concretamente, cien cementerios de la provincia de Castellón.

Seeing Eternity: How Earlier Poets Can Open Our Eyes to Faith
Authors: Wilcox Helen
Published: March 2024

This article explores how poets from the seventeenth century, including John Donne, George Herbert, Gertrude More and Henry Vaughan, can still speak to modern readers with immediacy and vision about matters of faith. In the first two sections, the poets are shown to give voice to such enduring human emotions in response to God as wonder and joy but also as sorrow and frustration, challenging us as readers to experience faith more richly and deeply. In the third section, the poets are shown to be concerned with the same fundamental questions as we are today. Their works remain powerful in their beauty, surprising in their discoveries and reassuring in their humanness before God.
Ideological repetition and time trauma
Authors: Kelly David
Published: March 2024

In this analysis, the author analyzes Jindřich
Polák’s 1977
sf comedy
Tomorrow I’ll Wake Up and Scald Myself with Tea
and its implications regarding time travel, ideology, and repetition. In exploring the paradoxes present in time-travel fiction, the article finds there exists a concurrent trauma for the individuals involved, stemming primarily from the splitting-then-reintegrating of the self in the wake of the expedition. The film – centering around a group of former Nazis, whose plan is practically thwarted through a set of comically tragic circumstances regarding the aircraft’s pilot – offers a humorous approach to totalitarian discourse, pointing out the fallibility of said institutions and showing the pitfalls of adherence to Nazi ideology. The author draws on modern instances of fascist ideology and connects them to the comedic situations presented in Polák’s film, putting forth a critical approach to the identification of Nazi modernism as comprised solely of loss and lack.
Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors
Authors: Matsuoka Tomoki , Sawada Ryo
Published: March 2024

Recent observations of supernovae (SNe) have indicated that a fraction of massive stars possess dense circumstellar medium (CSM) at the moment of their core collapses. They suggest the presence of additional activities of the SN progenitor driving the enhancement of the mass-loss rate, and some physical processes attributing to a single star’s activities have been considered. In this study, we carry out binary evolutionary simulations of massive stars by MESA and investigate effects on the subsequent CSM formation through hydrodynamical simulations by PLUTO. We show that the mass transfer rate in a binary can increase at the beginning of the Roche lobe overflow, and this enhancement would be associated with the structure of the CSM before the explosion. We also illustrate that, depending on the orbital period of the binary, the density structure of the CSM can have a diverse distribution, including shell-like and cliff-like structures. These characteristic structures appear within the length scale of ∼1017 cm and could be traced by long-term observations of SNe, if the slow velocity of the CSM is assumed (∼10 km s−1). Our results highlight the importance of binary interaction in the aspect of reproducing the diversity of the CSM configuration.

Authors: Gim Hansung B. , Reines Amy E.
Published: March 2024

Henize 2–10 is a dwarf starburst galaxy hosting a ∼106
M
⊙ black hole (BH) that is driving an ionized outflow and triggering star formation within the central ∼100 pc of the galaxy. Here, we present Atacama Large Millimeter/submillimeter Array continuum observations from 99 to 340 GHz, as well as spectral line observations of the molecules CO (1–0, 3–2), HCN (1–0, 3–2), and HCO+ (1–0, 3–2), with a focus on the BH and its vicinity. Incorporating centimeter-wave radio measurements from the literature, we show that the spectral energy distribution of the BH is dominated by synchrotron emission from 1.4 to 340 GHz, with a spectral index of α ≈ − 0.5. We analyze the spectral line data and identify an elongated molecular gas structure around the BH with a velocity distinct from the surrounding regions. The physical extent of this molecular gas structure is ≈130 pc × 30 pc and the molecular gas mass is ∼106
M
⊙. Despite an abundance of molecular gas in this general region, the position of the BH is significantly offset from the peak intensity, which may explain why the BH is radiating at a very low Eddington ratio. Our analysis of the spatially resolved line ratio between CO J = 3–2 and J = 1–0 implies that the CO gas in the vicinity of the BH is highly excited, particularly at the interface between the BH outflow and the regions of triggered star formation. This suggests that the cold molecular gas is being shocked by the bipolar outflow from the BH, supporting the case for positive BH feedback.
Significant Cocoon Emission and Photosphere Duration Stretching in GRB 211211A: A Burst from a Neutron Star−Black Hole Merger
Authors: Meng Yan-Zhi , Wang Xiangyu Ivy , Liu Zi-Ke
Published: March 2024

The radiation mechanism (thermal photosphere or magnetic synchrotron) and the progenitor of gamma-ray bursts (GRBs) are under hot debate. Recently discovered, the prompt long-duration (∼10 s, normally from the collapse of massive stars) property of GRB 211211A strongly conflicts with its association with a kilonova (normally from the merger of two compact objects, NS–NS, NS–BH, or NS–WD, duration ≲2 s). In this paper, we find that the probability photosphere model with a structured jet can satisfactorily explain this peculiar long duration, through the duration stretching effect (∼3 times) on the intrinsic longer (∼3 s) duration of an NS–BH merger, the observed empirical 2SBPL spectrum (with soft low-energy index α of ∼−1), and its evolution. In addition, much evidence of the NS–BH merger origin is found, especially the good fit of the afterglow-subtracted optical−near-IR light curves by the significant thermal cocoon emission and the sole thermal “red” kilonova component. Finally, a convincing new explanation for the X-ray afterglow plateau is revealed.
Testing Cosmic-Ray Propagation Scenarios with AMS-02 and Voyager Data
Authors: Silver Ethan , Orlando Elena
Published: March 2024

AMS-02 on board the International Space Station provides precise measurements of cosmic rays (CR) near Earth, while Voyager measures CRs in the local interstellar medium, beyond the effects of solar modulation. Based on these data, we test and revise various CR propagation scenarios under standard assumptions: pure diffusion, diffusion with convection, diffusion with reacceleration, and diffusion with reacceleration and convection. We report on the scenarios’ performance against CR measurements, aiming to limit the number of model parameters as much as possible. For each scenario, we find parameters that are able to reproduce Voyager and AMS-02 data for the entire energy band for all the CR species tested. Above several GV, we observe a similar injection spectral index for He and C, with He harder than H. Some scenarios previously disfavored are now reconsidered. For example, contrary to usual assumptions, we find that the pure diffusion scenario does not need an upturn in the diffusion coefficient at low energy, while it needs the same number of low-energy breaks in the injection spectrum as diffusive-reacceleration scenarios. We show that scenarios differ in modeled spectra of one order of magnitude for positrons at ∼1 GeV and of a factor of 2 for antiprotons at several GV. The force-field approximation describes well the AMS-02 and Voyager spectra analyzed, except antiprotons. We confirm the ∼10 GeV excess in the antiproton spectrum for all scenarios. Also, for all scenarios, the resulting modulation should be stronger for positrons than for nuclei, with reacceleration models requiring much larger modulation.
Do Faculae Affect Autocorrelation Rotation Periods in Sun-like Stars?
Authors: Li Canis , Basri Gibor
Published: March 2024

Rotational periods derived from autocorrelation function (ACF) techniques on stars photometrically similar to the Sun in Kepler data have proven difficult to reliably determine. We investigate various instrumental and astrophysical factors affecting the accuracy of these measurements, including the effects of observational windows and noise, stellar activity and inclination, spectral passbands, and the separate normalization of contiguous segments. We validate that the flux variations due to faculae are very periodic, but starspots are the dominant source of bolometric and visible differential variability in Sun-like stars on rotational timescales. We quantify how much stronger the relative contribution of faculae would have to be to render Sun-like light curves periodic enough to reliably measure with autocorrelation methods. We also quantify how long starspot lifetimes need to be to render pure spot light curves periodic enough. In general, longer observational windows yield more accurate ACF measurements, even when faculae are not present. Due to the enhancement of the relative contribution of faculae, observing stars with intermediate inclinations, during activity minima, and/or through bluer passbands has the effect of strengthening the periodicity of the light curve. We search for other manifestations of faculae in broadband photometry of Sun-like stars and conclude that without absolute flux measurements or restriction to shorter-wavelength passbands, differential light curves are uninformative about faculae.

We explore the galaxy-halo connection information that is available in low-redshift samples from the early data release of the Dark Energy Spectroscopic Instrument (DESI). We model the halo occupation distribution (HOD) from z = 0.1 to 0.3 using Survey Validation 3 (SV3; a.k.a., the One-Percent Survey) data of the DESI Bright Galaxy Survey. In addition to more commonly used metrics, we incorporate counts-in-cylinders (CiC) measurements, which drastically tighten HOD constraints. Our analysis is aided by the Python package, galtab, which enables the rapid, precise prediction of CiC for any HOD model available in halotools. This methodology allows our Markov chains to converge with much fewer trial points, and enables even more drastic speedups due to its GPU portability. Our HOD fits constrain characteristic halo masses tightly and provide statistical evidence for assembly bias, especially at lower luminosity thresholds: the HOD of central galaxies in z ∼ 0.15 samples with limiting absolute magnitude M

r
< −20.0 and M

r
< −20.5 samples is positively correlated with halo concentration with a significance of 99.9% and 99.5%, respectively. Our models also favor positive central assembly bias for the brighter M

r
< −21.0 sample at z ∼ 0.25 (94.8% significance), but there is no significant evidence for assembly bias with the same luminosity threshold at z ∼ 0.15. We provide our constraints for each threshold sample’s characteristic halo masses, assembly bias, and other HOD parameters. These constraints are expected to be significantly tightened with future DESI data, which will span an area 100 times larger than that of SV3.
A Detectable Ultra-high-energy Cosmic-Ray Outburst from GRB 221009A
Authors: He Hao-Ning , Zhang B. Theodore , Fan Yi-Zhong
Published: March 2024

Gamma-ray bursts (GRBs) have been proposed as one of the promising sources of ultra-high-energy cosmic rays (UHECRs), but observational evidence is still lacking. The nearby brightest of all time GRB 221009A, a once in 1000 yr event, is able to accelerate protons to ∼103 EeV, and then generate extremly energetic neutrons via the photomeson production interaction. Protons arriving at the Milky Way are dominated by neutron-decay-induced protons. The intergalactic magnetic fields would not yield a sizable delay of the ≥10 EeV cosmic rays if its strength is ≲10−13 G, while Galactic magnetic fields would cause a significant time delay. We predict that a UHECR burst from GRB 221009A would be detectable by the Pierre Auger Observatory and the TA×4, within ∼10 yr. The detection of such a UHECR outburst will provide the direct evidence for UHECR acceleration in GRBs.
On Boundary Conditions for Magnetohydrodynamic Waves in Flux Tubes with a Pressure Jump

Published: March 2024

It is proved that the recent paper by Yelagandula on “a new insight” on the boundary conditions to be applied to magnetohydrodynamic waves in magnetic flux tubes with a finite thermal pressure jump at the boundary is fundamentally wrong. It exploits the wrong variables and assumes a fixed instead of a moving boundary.
Galactic Archeology with Luminous Red Giant Oscillations in Gaia DR3 Photometry
Authors: Nnadi Bryan , Grunblatt Samuel
Published: March 2024

Asteroseismology has significantly advanced the field of Galactic archeology, providing essential insights into the formation and evolution of our Galaxy. Here we present an asteroseismic analysis of 103 luminous red giant stars that were observed by Gaia in our Galaxy and the Large Magellanic Cloud. Leveraging a period–luminosity–amplitude relationship determined using data from the OGLE mission, we measure distances to these stars of up to 100 kpc, probing distances more than a factor of 2 beyond where Gaia parallaxes can be measured accurately. We have determined distance uncertainties of 8% or better for 80% of the stars in our sample and reduced known distance uncertainties for stars in this sample by more than a factor of 2 on average. Applying this approach to future Gaia data releases can provide more precise and accurate distances and constrain fundamental properties for 10,000+ stars across our Galaxy.
Negative Cosmic Evolution of BL Lac Objects from the Sloan Digital Sky Survey
Authors: Clapp Octavia D. , Plotkin Richard M. , Anderson Scott F.
Published: March 2024

BL Lacertae (BL Lac) objects are a type of active galactic nucleus (AGN) characterized by featureless optical spectra, where a relativistic jet is oriented toward the observer. By studying BL Lacs objects, we improve our understanding of accretion processes, high-energy particle acceleration, magnetic field structures in extreme environments, and galaxy formation and evolution. Generally, luminous AGNs (i.e., quasars) exhibit “positive” evolution. This means that, on average, quasars are more numerous and/or more luminous in the early Universe, at higher redshifts, than they are today. However, the evolution of BL Lacs has been long disputed, in part due to selection biases and small sample sizes. Here we perform the luminosity–volume test of BL Lac evolution on a uniformly selected sample and find that BL Lacs instead exhibit mild negative evolution. We conclude by putting our results into context with previous studies on BL Lac evolution.
A Possible Extremely Fast Spinning White Dwarf in the Intermediate Polar SDSS J0932+47
Authors: Tweddale Jordan , Garnavich Peter , Kennedy Mark R.
Published: March 2024

We analyze the far-ultraviolet light curve of the intermediate polar (IP) candidate SDSS-J093249.57+472523.0 (J0932+47), as observed by Hubble Space Telescope/Cosmic Origins Spectrograph. The power spectrum displays two periodicities at frequencies of 2.01 and 0.462 cycles minute−1, corresponding to periods of 29.8 and 130 s. We estimate the significance of the 29.8 s peak to be 3σ. The detection of the 130 s signal is less secure. If the 29.8 s signal is generated by a rotating white dwarf (WD), then J0932+47 would possess one of the fastest spinning WDs among known IPs. The N v/C iv and Si iv/C iv line ratios are larger than typically seen in cataclysmic variables (CVs), and anomalous line ratios are seen in several CVs with rapidly rotating WDs. Alternatively, the periodicities are in the range typical of dwarf nova oscillations.
Quasars versus Microquasars: Scaling and Particle Acceleration
Authors: Katz J. I.
Published: March 2024

Quasars and microquasars both contain accreting black holes and power nonthermal double radio sources, but differ in more than their scales: Quasars are proportionally much more efficient accelerators of energetic electrons. The radio luminosity of the double radio sources associated with quasars, reflecting the long-time average of the particle acceleration power, is often 1%–30% of the quasar’s bolometric luminosity; in microquasars the fraction is ≲10−5. This may be explained by the scaling of accretion disk parameters with the black hole mass.
