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 Exclusion criteria included case reports, case series, unpublished trials, or conference abstracts.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.
Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors
Authors: Matsuoka Tomoki , Sawada Ryo 
Published: March 2024

Abstract
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.
The ALMA View of Positive Black Hole Feedback in the Dwarf Galaxy Henize 2–10
Authors: Gim Hansung B. , Reines Amy E. 
Published: March 2024

Abstract
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

Abstract
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

Abstract
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

Abstract
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.

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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.
Contrasts in Perception of the Interaction Between Non-Native Species and Climate Change
Authors: Perrin Sam , Lundmark Carina , Wenaas Camilla Perrin , Finstad Anders Gravbrøt 
Published: March 2024

Over the last century, intensification of human movement worldwide has resulted in a large-scale redistribution of species, which has been compounded in recent decades by climate change. The interaction of these two phenomena have resulted in a number of complexities and challenges for regarding management of non-native species. As effective management can be hampered by disconnects between scientific researchers, natural resource managers and the general public, assessing consensus between these groups is crucial.
Here, we undertake an explorative approach to analyse three groups of people concerned with the management of freshwater ecosystems - recreational fishers, natural resource managers and scientific researchers - in order to better understand consensus or lack thereof regarding the interaction between non-native species and climate change.
We found that while scientific researchers and managers had varying opinions on the management of non-native species as driven by climate change, recreational fishers were almost unanimously opposed to the potential presence of non-native species, regardless of the nature of their introduction. Additionally, definitions of what constitutes a non-native species varied greatly between and within the different groups.
Our results underline both the current lack of consensus on the definition and management of non-native species and a disconnect between and within the three groups regarding both the nature of non-native species and the range-shifting effects of climate change.
Moines et chanoines dans le diocèse de Vienne aux ix e et x e siècles
Authors: Nimmegeers Nathanaël 
Published: March 2024

Le chapitre cathédral de Vienne, fondé à la fin du règne royal de Charlemagne, présente de nombreuses caractéristiques méridionales. S’il s’affirme rapidement comme une institution solide et influente, il constitue toutefois une expérience isolée à l’échelle provinciale. La cité archiépiscopale compte, en outre, de nombreuses abbayes. Les plus importantes et les plus prestigieuses d’entre elles, Saint-Pierre et Saint-André-la-Bas, accueillent des chanoines pendant quelques décennies avant de retourner à l’état monastique. Ces mutations institutionnelles et cette porosité du monde des moines avec celui des chanoines existent aussi à Romans. Abbaye archiépiscopale fondée vers 840 aux confins du diocèse de Vienne, elle devient en effet définitivement une collégiale vers 950 au terme d’un processus de transformation long et chaotique.
Le terme « réforme » est-il adapté pour décrire les changements qui s’opèrent dans les communautés cléricales entre le ix e et le x e siècle ?
Authors: Barrow Julia 
Published: March 2024

Les historiens utilisent très souvent la réforme comme cadre privilégié pour l’histoire ecclésiastique médiévale, dans les travaux qui portent sur le clergé mais également sur le monachisme ou la papauté. Il semble cependant nécessaire de se détacher quelque peu d’un usage peu réfléchi du terme « réforme » et de se pencher plus en détail sur le vocabulaire utilisé dans les sources de l’époque. C’est ce que propose de faire le présent article, qui examine les règles destinées au clergé, les textes conciliaires et les chartes rédigés entre 750 et 1100 et qui prescrivent, planifient ou justifient des changements dans les institutions religieuses. Cette analyse révèle un contraste entre la relative abondance de langage programmatique pour proposer des changements dans les communautés monastiques et le discours plus sec et pragmatique qui décrit ceux proposés au clergé – effet de contraste qui ne s’atténuera qu’avec l’émergence des chanoines réguliers au xi e siècle.
