Abstract
A new approach to the problem of the passage of the extraordinary wave through the region of the electron–cyclotron resonance in inhomogeneous plasma was considered in the framework of the full set of Maxwell’s equations, taking into account the effects of spatial dispersion and resonance dissipation. For the model one-dimensional geometry, field distributions were calculated in the vicinity of the cyclotron resonance at the second harmonic for the normal incidence of the extraordinary wave and the reflection, transmission, and absorption coefficients were found depending on the parameters of the resonance region. As a result, the fine effect of the reflection of electromagnetic radiation from the cyclotron resonance region in transparent plasma was described and the results were compared with the observations of this effect in the experiments on the microwave heating of the plasma at the L-2M stellarator.
Page curves for accelerating black holes
Authors: Yu Ming-Hui , Ge Xian-Hui , Lu Cheng-Yuan 
Published: December 2023

AbstractThe island paradigm for the fine-grained entropy of Hawking radiation is applied to eternal charged accelerating black holes. In the absence of the island, the entanglement entropy grows linearly and divergent at late times, while once the island outside the event horizon is taken into account, the unitary Page curve is reproduced naturally. The impact of the charge and the acceleration on Page curves is investigated at late times. For the Page time and the scrambling time, they both increase as the acceleration increases, while decreasing as the charge increases. In particular, neutral black holes have the largest Page time and scrambling time. It is worth noting that the Page time and the scrambling time is divergent at the extremal case, which implies that islands may be related to the causal structure of spacetime.
Comparing f(R) and scale-dependent gravities
Authors: Calzada Pelayo V. , Rincón Ángel , Bargueño Pedro 
Published: December 2023

AbstractIn this work, we prove that every f(R) gravity can be represented as a scale-dependent one, but not every scale-dependent gravity can be represented in the f(R) framework. Therefore, the f(R) formalism is strictly included in the scale-dependent approach. This scale-dependent representation of f(R) gravity allows for a novel approach toward both theories. In particular, we obtain a novel dynamical characterization of light rings for f(R(r)) theories and we have shown that some previous solutions of f(R) theories correspond to solutions of scale-dependent gravity. Finally, new solutions to scale-dependent gravity are identified with the help of the f(R) representation.
Pole-skipping of gravitational waves in the backgrounds of four-dimensional massive black holes
Authors: Grozdanov Sašo , Vrbica Mile 
Published: December 2023

AbstractPole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary conditions at the horizon at an infinite discrete set of Fourier modes. The phenomenon has been best understood, when such a description exists, in terms of dual holographic (AdS/CFT) correlation functions that take the value of ‘0/0’ at these special points. In this work, we investigate details of pole-skipping purely from the point of view of classical gravity in 4d massive black hole geometries with flat, spherical and hyperbolic horizons, and with an arbitrary cosmological constant. We show that pole-skipping points naturally fall into two categories: the algebraically special points and a set of pole-skipping points that is common to the even and odd channels of perturbations. Our analysis utilises and generalises (to arbitrary maximally symmetric horizon topology and cosmological constant) the ‘integrable’ structure of the Darboux transformations, which relate the master field equations that describe the evolution of gravitational perturbations in the two channels. Finally, we provide new insights into a number of special cases: spherical black holes, asymptotically Anti-de Sitter black branes and pole-skipping at the cosmological horizon in de Sitter space.
No long hair behaviors of ultra-compact objects
Authors: Liu Guohua , Peng Yan 
Published: December 2023

AbstractWe investigate distributions of matter fields outside spherically symmetric ultra-compact objects with null circular orbits in the asymptotically flat background. Based on the dominant energy and the non-negative trace conditions, we prove the existence of effective radius of matter field hairs outside horizonless ultra-compact objects. We also analytically find a no long hair behavior, which states that the effective radius of matter field hairs cannot extend beyond the outermost null circular orbit of horizonless ultra-compact objects.
Changing Patterns of Stroke and Subtypes Attributable to High Systolic Blood Pressure in China From 1990 to 2019
Authors: Gao Ying , Liu Kangding , Fang Shaokuan 
Published: December 2023

BACKGROUND:
It is unknown whether high systolic blood pressure had a similar effect on the disease burden of stroke subtypes. The aim of our study is to compare the long-term trends of stroke subtypes and sex groups attributable to high systolic blood pressure in China from 1990 to 2019.

METHODS:
Data about the age-standardized mortality rate and the age-standardized disability-adjusted life-year rate of stroke subtypes attributable to high systolic blood pressure in China were extracted in GBD (Global Burden of Disease) 2019. The trends in the age-standardized mortality rate and the age-standardized disability-adjusted life-year rate were calculated using the liner regression and age-period-cohort method, adjusted for age, period, and cohort.

RESULTS:
The estimated annual percentage change for mortality of stroke attributable to high systolic blood pressure was different from subtypes, with an estimated annual percentage change and 95% CI of 0.56 (0.37–0.74) for ischemic stroke (IS), −1.52 (−1.97 to −1.07) for intracerebral hemorrhage, and −7.02 (−7.86 to −6.17) for subarachnoid hemorrhage (SAH). The curve of the net drifts showed a downward trend for intracerebral hemorrhage and SAH, but that showed a stable trend for IS. The curve of local drifts showed a slow upward trend with age for IS, a slow downward trend for intracerebral hemorrhage, and a sharp downward trend for SAH. The drift curves showed different trends for males and females. The proportion of stroke mortality in young males was gradually increasing. The cohort rate ratio varied by subtypes, with the greatest decline for SAH, a slight decrease for intracerebral hemorrhage, and a slight increase for IS. The period rate ratio had decreased over the past 3 decades, with the greatest decline for SAH and the weakest decrease for IS. Moreover, both the period and cohort rate ratios for IS mortality due to high systolic blood pressure in males have increased significantly over the past 3 decades.

CONCLUSIONS:
Our results provided strong evidence that the disease burden of stroke attributable to high systolic blood pressure varied by subtypes and sex in China from 1990 to 2019. The age-standardized mortality rate and the age-standardized disability-adjusted life-year rate decreased for hemorrhagic stroke but increased for IS. Males had a higher mortality and exposure risk but a slighter decreasing trend than females. Our study suggested that greater attention should be given to the prevention of the burden of IS attributable to systolic blood pressure in China, especially for males.
Domain-Independent Lifelong Problem Solving Through Distributed ALife Actors

Published: December 2023

AbstractA domain-independent problem-solving system based on principles of Artificial Life is introduced. In this system, DIAS, the input and output dimensions of the domain are laid out in a spatial medium. A population of actors, each seeing only part of this medium, solves problems collectively in it. The process is independent of the domain and can be implemented through different kinds of actors. Through a set of experiments on various problem domains, DIAS is shown able to solve problems with different dimensionality and complexity, to require no hyperparameter tuning for new problems, and to exhibit lifelong learning, that is, to adapt rapidly to run-time changes in the problem domain, and to do it better than a standard, noncollective approach. DIAS therefore demonstrates a role for ALife in building scalable, general, and adaptive problem-solving systems.
Strong Extratropical Impact on Observed ENSO

Published: December 2023

Abstract
Previous studies have indicated that the extratropics can influence ENSO via specific processes. However, it is still unclear to what extent ENSO is influenced by the extratropics in observation. Now we assess this issue by applying the regional data assimilation (RDA) approach in an advanced model, the GFDL CM2.1. Our study confirms a strong extratropical impact on observed ENSO. Quantitatively, the extratropical atmospheric variability poleward of 20° explains 56% of the observed variance of ENSO and greatly influences ∼67% of observed El Niño events during 1969–2008. This extratropical impact is still significant even as far as poleward of 30°. Furthermore, the impact from the southern extratropics is slightly stronger than that from the northern extratropics, partly caused by the Pacific ITCZ location north of the equator and different mixed-layer depth along the northern Pacific meridional mode (NPMM) and the southern Pacific meridional mode (SPMM). Our study further shows that all of three super El Niño events, those in 1972/73, 1982/83, and 1997/98, are influenced greatly by both hemispheric extratropics, with NPMM and SPMM interfering constructively, while most weak and moderate El Niño events are triggered by only one hemispheric extratropics, with NPMM and SPMM interfering destructively. Besides the extratropical Pacific influence on ENSO via NPMM/SPMM, the extratropics also has a potential impact on ENSO by influencing other tropical oceans and then by interbasin interactions.

Published: December 2023

Objective: Assessing mobility among people with HIV is an important consideration when measuring HIV incidence, prevalence, and the care continuum in the United States. Our aims were to measure mobility among people with HIV compared with the general population and to examine factors associated with migration among people with HIV. Methods: We calculated state-to-state move-in and move-out migration rates for 2011 through 2019 using National HIV Surveillance System data for people with HIV and using US Census data for the general population. For people with HIV, we also assessed the association between migration and HIV care outcomes. Results: From 2011 through 2019, the US general population had stable migration, whereas migration rates among people with HIV fluctuated and were higher than among the general population. Among people with HIV, migration rates in 2019 were higher among people assigned male sex at birth versus female sex at birth, among people aged ≤24 years versus ≥25 years, among people with HIV infection attributed to male-to-male sexual contact versus other transmission categories, and among non-Hispanic Other people (ie, American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or multiple races) versus Hispanic, non-Hispanic Black, and non-Hispanic White people. Receipt of HIV medical care (90.3% vs 75.5%) and achieving viral suppression (72.1% vs 65.3%) were higher among people with HIV who migrated versus those who did not. Conclusions: People with HIV in the United States are more mobile than the general population. Determining the mobility of people with HIV can help with strategic allocation of HIV prevention and care resources.
Equity Work Among Accredited Health Departments in the United States, 2015-2021
Authors: Lang Britt , Kronstadt Jessica , Rich Naomi 
Published: December 2023

Objectives: Minimal research has examined the number of health departments conducting work related to equity and/or the kind of work, if any, they are conducting. We examined the relationship between public health accreditation and work related to health equity by analyzing accredited health departments’ responses to a prompt in the Public Health Accreditation Board’s (PHAB’s) annual report. Methods: We analyzed self-reported responses from accredited health departments to questions about emerging public health issues and innovations in PHAB’s annual report. We identified themes using a priori and inductive coding. Results: A total of 316 health departments submitted an annual report from January 2015 through December 2021. Of those health departments, 283 (89.6%) stated in their annual report that they engaged in work related to health equity, 50 (17.7%) of which provided a narrative about this work. Of those 50 health departments, the most common theme reported was community partnership, described by 23 (46.0%) health departments. The next most reported themes were COVID-19 vaccine access for racially or socioeconomically marginalized communities (n = 17, 34.0%) and programs related to health equity (n = 16, 32.0%). Conclusions: We found that most accredited health departments conduct work related to health equity. Further research is needed to examine characteristics that influence a health department’s likelihood of conducting equity work. Models and resources on how health departments, particularly small health departments, can begin equity work would be valuable.

Published: December 2023

Background: To study the impact of early in comparison to late catheter removal following acute urine retention (AUR) secondary to benign prostatic hyperplasia (BPH) using silodosin therapy on the outcome of trial without catheter (TWOC). Methods: Two hundred sixty patients with AUR 2ry to BPH were catheterized then were randomly divided to receive silodosin 8 mg either for three or 7 days followed by catheter removal and successful voiding unaided was assessed. Results: Out of the 260 men (mean age 64.8 ± 6.5 years) treated, 74 men who were receiving 3 days of silodosin and 88 patients who were receiving 7 days of silodosin didn’t require re-catheterization on the day of TWOC (57% and 68% respectively, p = 0.096). Complications like urinary leakage, acute urinary tract infection, hematuria, or catheter blockage recorded in 21 men (16.2%) who received 3 days of silodosin, and in 63 men (48.5%) who received 7 days of silodosin ( p ⩽ 0.001). Conclusion: Patients catheterized after AUR 2ry to BPH can spontaneously void following catheter removal if treated by silodosin, independent of the catheterization duration, while side effects have increased with prolonged catheterization.

Published: December 2023

Background: This study was designed to evaluate the effects of low-frequency electroacupuncture (EA) on glucose and lipid disturbances in a rat model of polycystic ovary syndrome (PCOS) characterized by insulin resistance (IR) and hepatic steatosis. Methods: The PCOS rat model was induced by continuous administration of letrozole (LET) combined with a high-fat diet (HFD). Female Sprague–Dawley rats were divided into the following four groups: control, control + EA, LET + HFD and LET + HFD + EA. EA was administered five or six times a week with a maximum of 20 treatment sessions. Body weight, estrous cyclicity, hormonal status, glucose and insulin tolerance, lipid profiles, liver inflammation factors, liver morphology and changes in the phosphatidylinositol 3-kinase (PI3-K)/Akt (protein kinase B) pathway were evaluated. Results: The rat model presented anovulatory cycles, increased body weight, elevated testosterone, abnormal glucose and lipid metabolism, IR, liver inflammation, hepatic steatosis and dysregulation of the insulin-mediated PI3-K/Akt signaling axis. EA reduced fasting blood glucose, fasting insulin, area under the curve for glucose, homeostasis model assessment of IR indices, triglycerides and free fatty acids, and alleviated hepatic steatosis. Furthermore, low-frequency EA downregulated mRNA expression of tumor necrosis factor (TNF)-α and interleukin (IL)-6, upregulated mRNA expression of peroxisome proliferator-activated receptor (PPAR)-α, increased protein expression of phosphorylated (p)-Akt (Ser473), p-glycogen synthase kinase (GSK) 3β (Ser9) and glucose transporter 4 (GLUT4), increased the ratio of p-GSK3β to GSK3β and downregulated protein expression of GSK3β. Conclusion: An obese PCOS rat model with IR and hepatic steatosis was successfully established by the combination of LET and HFD. EA improved dysfunctional glucose and lipid metabolism in this PCOS-IR rat model, and the molecular mechanism appeared to involve regulation of the expression of key molecules of the PI3-K/Akt insulin signaling pathway in the liver.

Published: December 2023

This study examines the effects of share repurchase announcements on Taiwanese firms after various financial practices and decisions from 2000 to 2020. First, we discuss whether there is a significant abnormal return on the price around share repurchase announcement. Furthermore, we explore whether firms take advantage of buyback announcements to signal the outsiders that the company’s stock price is undervalued. Second, we discuss whether the repurchase announcements have abnormal returns after financing or dividend distribution decisions as companies implement these decisions in response to future operating plans. Further, we explore whether there is a conflict between these funding operation policies and the repurchase announcement.  According to our results, there is an opposing effect between seasoned equity offering and share repurchase announcements. We found the effect of the announcement of share repurchase after a cash dividend is better than a stock dividend. The results also show that the effect of a share repurchase announcement after the issuance of convertible bonds is better than an ordinary corporate bond issue, especially the firms with a low market-to-book ratio. It means that convertible bonds can reduce liabilities if the investors convert the debt into equity and improve the company’s capital structure. JEL Codes: G14, G30

Published: December 2023

Purpose The purpose of this study was to investigate the effect of gas tamponade on microvascular changes in patients with rhegmatogenous retinal detachment (RRD), who underwent pars plana vitrectomy (PPV), using optical coherence tomography angiography (OCTA). Methods Participants in this study were 48 patients with RRD, who were treated with PPV and gas tamponade without internal limiting membrane peeling. All participants underwent slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography and optical coherence tomography angiography at month 6 postoperatively. The fellow untreated eyes were also examined and served as the control data. Results A statistically significant enlargement in the foveal avascular zone (FAZ) in both the superficial (p = 0.002) and the deep capillary plexus (p = 0.01) was noticed 6 months postoperatively in patients with RRD treated with PPV compared to the fellow eyes. The foveal avascular zone perimeter was increased in the operated eyes in the deep capillary plexus (p = 0.0003) and the foveal avascular zone circularity was decreased in both the superficial (p = 0.045) and the deep capillary plexus (p < 0.001) compared to the fellow eyes. The vessel density was not significantly different between the operated and the fellow eyes in the superficial and the deep capillary plexus. The vessel density and the foveal avascular zone parameters were comparable between the C3F8 and SF6 groups. Conclusion Specific microvascular indices as measured by OCTA were statistically different between the operated and the fellow eyes in the superficial and deep capillary plexus. C3F8 and SF6 as gas tamponades did not seem to differ in their impact on the microvascular parameters.
