Authors: Silva Gisele Sampaio , de Andrade João Brainer Clares , Martins Eduardo Bello , Santo Karla , Julia Machline-Carrion M. 
Published: September 2024

AbstractHypertension is the leading risk factor for stroke, causing about 60% of cases. Effective blood pressure control is vital for preventing recurrent ischemic strokes, with studies showing mixed results. Intensive control reduces cardiovascular events, as seen in the SPRINT, PROGRESS and STEP studies, while trials like RESPECT show no difference. Technological advances like AI and wearables enhance management, but challenges remain in achieving equitable control, especially for minorities.
Capacity analysis over fractional order Rayleigh fading channel under additive white generalized Gaussian noise
Authors: Kakavand Mehran , Hassannejad Bibalan Mohammadreza , Baghani Mina 
Published: September 2024

AbstractThis study presents an innovative fractional order Rayleigh fading model that can be used for channel capacity estimation in the presence of additive white generalized Gaussian noise. The proposed model assumes that the real and imaginary parts of channel gains are generalized Gaussian random variables, which makes it possible to consider the traditional Rayleigh fading model as a special case of fractional order Rayleigh fading. Compared to the Rayleigh model, the fractional order Rayleigh fading model offers a more precise representation of new real‐world communication, such as integrating terrestrial and underwater networks in sixth‐generation communications channels. The probability density function of the channel gain with additive white generalized Gaussian noise is analyzed here. Furthermore, the ergodic and outage capacities of the channel are determined, taking into account the assumption that the channel state information is only available at the receiver. The ergodic capacity is calculated using Meijer's G‐functions, resulting in a closed‐form expression. Numerical simulations demonstrate the superiority of the fractional order Rayleigh fading model over the Rayleigh channel. Moreover, the impact of ergodic and outage capacities under diverse channel characteristics is assessed.
Research on priority scheduling strategy for smoothing power fluctuations of microgrid tie‐lines based on PER‐DDPG algorithm

Published: September 2024

AbstractThe variability of renewable energy within microgrids (MGs) necessitates the smoothing of power fluctuations through the effective scheduling of internal power equipment. Otherwise, significant power variations on the tie‐line connecting the MG to the main power grid could occur. This study introduces an innovative scheduling strategy that utilizes a data‐driven approach, employing a deep reinforcement learning algorithm to achieve this smoothing effect. The strategy prioritizes the scheduling of MG's internal power devices, taking into account the stochastic charging patterns of electric vehicles. The scheduling optimization model is initially described as a Markov decision process with the goal of minimizing power fluctuations on the interconnection lines and operational costs of the MG. Subsequently, after preprocessing the historical operational data of the MG, an enhanced scheduling strategy is developed through a neural network learning process. Finally, the results from four scheduling scenarios demonstrate the significant impact of the proposed strategy. Comparisons of reward curves before and after data preprocessing underscore its importance. In contrast to optimization results from deep deterministic policy gradient, soft actor‐critic, and particle swarm optimization algorithms, the superiority of the deep deterministic policy gradient algorithm with the addition of a priority experience replay mechanism is highlighted.
TriPoD: Tri-Population size distributions for Dust evolution
Authors: Pfeil Thomas , Birnstiel Til , Klahr Hubert 
Published: September 2024

Context. Dust coagulation and fragmentation impact the structure and evolution of protoplanetary disks and set the initial conditions for planet formation. Dust grains dominate the opacities, they determine the cooling times of the gas via thermal accommodation in collisions, they influence the ionization state of the gas, and the available grain surface area is an important parameter for the chemistry in protoplanetary disks. Therefore, dust evolution is an effect that should not be ignored in numerical studies of protoplanetary disks. Available dust coagulation models are, however, too computationally expensive to be implemented in large-scale hydrodynamic simulations. This limits detailed numerical studies of protoplanetary disks, including these effects, mostly to one-dimensional models.
Aims. We aim to develop a simple – yet accurate – dust coagulation model that can be easily implemented in hydrodynamic simulations of protoplanetary disks. Our model shall not significantly increase the computational cost of simulations and provide information about the local grain size distribution.
Methods. The local dust size distributions are assumed to be truncated power laws. Such distributions can be fully characterized by only two dust fluids (large and small grains) and a maximum particle size, truncating the power law. We compare our model to state- of-the-art dust coagulation simulations and calibrate it to achieve a good fit with these sophisticated numerical methods.
Results. Running various parameter studies, we achieved a good fit between our simplified three-parameter model and DustPy, a state-of-the-art dust coagulation software.
Conclusions. We present TriPoD, a sub-grid dust coagulation model for the PLUTO code. With TriPoD, we can perform twodimensional, vertically integrated dust coagulation simulations on top of a hydrodynamic simulation. Studying the dust distributions in two-dimensional vortices and planet-disk systems is thus made possible.

Context. (4015) Wilson-Harrington (hereafter, WH) was discovered as a comet in 1949 but has a dynamical property consistent with that of a near-Earth asteroid. Although there is a report that the 1949 activity is associated with an ion tail, the cause of the activity has not yet been identified.
Aims. This work aims to reveal the mysterious comet-like activity of the near-Earth asteroid.
Methods. We conducted new polarimetric observations of WH from May 2022 to January 2023, reanalyses of the photographic plate images taken at the time of its discovery in 1949, and dust tail simulation modelings, where the dust terminal velocity and ejection epoch are taken into account.
Results. We found that this object shows polarization characteristics similar to those of low-albedo asteroids. We derived the geometric albedo ranging from pV = 0.076 ± 0.010 to pV = 0.094 ± 0.018 from our polarimetry (the values vary depending on the data used for fitting and the slope-albedo relationship coefficients). In addition, the 1949 image showed an increase in brightness around the nucleus. Furthermore, we found that the color of the tail is consistent with sunlight, suggesting that the 1949 activity is associated with dust ejection. From the dust tail analysis, ~9 × 105 kg of material was ejected episodically at a low velocity equivalent to or even slower than the escape velocity.
Conclusions. We conclude that WH is most likely an active asteroid of main belt origin and that the activity in 1949 was likely triggered by mass shedding due to fast rotation.
Environmental effects as a key factor in shaping star-forming S0 galaxies
Authors: Chen Pei-Bin , Wang Jun-Feng , Chen Yan-Mei , Xu Xiaoyu , Cao Tian-Wen 
Published: September 2024

Context. The origins of lenticular galaxies (S0s) can be classified into two main categories: “minor mergers” in low-density environments (LDEs) and “faded spirals” in high-density environments (HDEs). The transitional phase in the evolution of S0s, namely, star-forming lenticular galaxies (SFS0s), can serve as an important probe for analyzing the complex processes involved in the transformation between different galaxy types and the quenching of star formation (SF).
Aims. We attempt to find the impact of different environments on the global properties and spatially resolved quantities of SFS0s.
Methods. We selected 71 SFS0s from the SDSS-IV MaNGA Survey, comprising 23 SFS0s in HDEs (SFS0s_HE) and 48 SFS0s in LDEs (SFS0s_LE). We examined the effects of the environment, by studying the global properties, concentration index, and radial profiles of the derived quantities.
Results. The varied environments of SFS0s do not lead to any significant difference in global properties (e.g., Sérsic index). By calculating CIHα/cont, we observe that different environments may cause varying concentrations of SF. Specifically, SFS0s_LE, affected by external gas mergers or inflow, exhibit a more centrally concentrated SF (i.e., larger CIHα/cont). This trend is further supported by CISFR, Hα, which only considers the gas disk of the galaxy. This observation is aligned with the observed shrinking of gas disks in galaxies affected by ram-pressure stripping in HDEs. Furthermore, their ΣSFR or resolved sSFR are comparable. On average, SFS0s_LE display significantly higher values for both quantities. Finally, the observed Dn4000 and gas-phase metallicity gradient correspond well to their assumed origins. However, we did not find a significantly lower gas-phase metallicity in SFS0s_LE.
Conclusions. We suggest that different environments (i.e., origins) do not have a significant impact on the global properties of SFS0s, but they do indeed affect the distribution of SF. Considering the size of our sample and the unique nature of the galaxy, additional atomic and molecular gas data may provide further details to improve our understanding of these systems.

Background: Patients requiring extracorporeal life support (ECLS) support post-Norwood operation constitute an extremely high-risk group. Materials and methods: We retrospectively aimed to evaluate the relationship of hyperoxia with mortality and other clinical outcomes in patients who required ECLS following Norwood operation between January/2010 and December/2020 in a large volume center. Results: During the study period 65 patients required ECLS post-Norwood. Using receiver operating characteristic (ROC) curve analysis, mean PaO2 of 182 mmHg in the first 48-hour on ECLS was determined to have the optimal discriminatory ability for mortality (sensitivity 68%, specificity 70%). Of the 65 patients, 52% had PaO2 > 182 mmHg and were designated as hyperoxia group. Patients in the hyperoxia-group had longer cardiopulmonary bypass time (187 vs. 165 min, p = 0.023), shorter duration from CICU arrival to ECLS-cannulation (13.28 vs. 132.58 h, p = 0.003), higher serum lactate within 2-hours from ECLS-canulation (14.55 vs. 5.80, p = 0.01), higher ECLS flows in the first 4-hours (152.68 vs. 124.14, p = 0.006), and higher mortality (77% vs. 39%, p = 0.005). In the unadjusted-analysis, using a derived cut-point, patients in the hyperoxia-group had 5.15 higher odds of mortality (p = 0.003). However, this association was insignificant when adjusting for confounding variables (p = 0.104). Using a functional status scale, new morbidity (38% vs. 21%), and unfavorable outcomes (13% vs. 5%) were higher in the hyperoxia group. Despite being higher in the hyperoxia group, this did not reach statistical significance. Conclusion: Neonates with hyperoxia (PaO2 > 182 Torr) during the first 48-hour of ECLS post-Norwood operation had 5 times higher odds of mortality in the unadjusted analysis, however, this was insignificant when adjusting for confounding variables. Patients in the hyperoxia group had shorter duration from CICU arrival to ECLS-cannulation, higher serum lactate prior to ECLS-canulation, and higher ECLS flows in the first 4-hours, (p < 0.05). Multicenter evaluation of this modifiable risk factor is imperative to improve the care of this high-risk cohort.

Published: September 2024

Zusammenfassung
Hintergrund Die Auswertung der onkologischen Ergebnisse nach radikaler Prostatektomie (RP) ist ein wichtiger Bestandteil der Qualitätskontrolle in Prostatakrebszentren.

Fragestellung Die Evaluation der onkologischen Ergebnisse nach RP in einer nicht-universitären Ausbildungsklinik in Deutschland und Vergleich mit anderen High-Volume-Prostatakarzinomzentren.

Material und Methoden 1161 Patienten nach RP wurden eingeschlossen und in 2 Risikogruppen eingeteilt. Low-risk: organbegrenztes PCa (pT2) und prostataspezifisches Antigen (PSA)≤ 20ng/ml und Gleason-Score (GS) 6–7b und pN0. High-risk: lokal fortgeschrittenes PCa (≥pT3a) und/oder PSA > 20ng/ml und/oder GS≥ 8 und/oder pN1. Risikogruppen und klinikopathologische Merkmale wurden in Beziehung mit biochemischem rezidiv(BCR)-freiem Überleben, karzinomspezifischem Überleben (CSS) und Gesamtüberleben (OS) gebracht.

Ergebnisse 10-Jahres-BCR-freies Überleben, CSS, OS betrugen 68,4% und 47,0%, 100% und 87,4% und 89,0% und 73,9% in der Low- und High-Gruppe (p<0,05 zwischen Risikogruppen).

Bei multivariater Cox-Regressionsanalyse war GS der signifikanteste prognostische Faktor für CSS (p=0,00001) und BCR-freies Überleben (p=0,00036). pN1-Stadium war stark mit CSS assoziiert (p=0,00004). Alter war der wichtigste Faktor für OS in der High-Risk-Gruppe (p=0,0011).

Schlussfolgerung RPE könnte in ausgewählten Fällen eine kurative Therapieoption für das lokal fortgeschrittene PCa sein. GS ist der wichtigste prognostische Faktor. Gute onkologische Ergebnisse können auch in nicht-universitären Ausbildungskliniken erzielt werden.
Recent Developments on the HI Gas of Low-Redshift Galaxies Seen by the 21 cm Emission Lines
Authors: Wang 王 Jing 菁 , Lin 林 Xuchen 旭辰 
Published: September 2024

Abstract
As a major interstellar medium, the atomic neutral hydrogen (H i) plays an important role in the galaxy evolution. It provides the ingredient for star formation, and sensitively traces the internal processes and external perturbations influencing the galaxy. With the beginning of many new radio telescopes and surveys, H i may make a more significant contribution to the understanding of galaxies in the near future. This review discusses the major development of the 21 cm emission-line H i observations and studies in the past few years, including its scaling relations with other galaxy properties, its kinematics and structures, its role in environmental studies, and its constraints on hydrodynamical simulations. The local-Universe H i scaling relations of stellar-mass-selected samples extend smoothly to 109
M
⊙ stellar mass, with a tentative evolution to the redshift of ∼ 0.1. The development of measurement techniques enables better estimations of H i non-circular motion, dispersion, and thickness, and new observations revealed extended or extra-planar H i structures, both helpfully constraining the gas accretion, stellar feedback, and star formation processes of galaxy evolution models. H i is very useful for tracing the satellite evolution in dense environments, the studies of which would benefit from ongoing blind H i surveys. Though simulations still cannot fully reproduce H i gas properties, they help to understand the role of possible factors in regulating H i properties.
Plasmonic coupling effect of annealed gold nanoarrays

Published: September 2024

Abstract
Periodic metal nanodisc arrays have the potential to exhibit regularly spaced large local field enhancements, especially when high-Q collective plasmonic grating resonances can be obtained. Here we demonstrate how Laser interference lithography (LIL) as a maskless and high throughput technique can be used to fabricate these on square centimeter areas. The drawback of LIL is the rather fixed ratio of the size of the individual nanostructure (d) to the period of the array (p) of about d/p ∼ 0.5 for the setup used in the current article, thereby, limiting its ability to create resonances with ultra-high quality factors (Q-factors). To improve the Q-factor of the resonances of the arrays, we study the effect of thermal annealing nanodisk arrays fabricated by LIL and a lift off process. The nanodisk arrays with periods of 400 nm and 500 nm exhibited a plasmonic resonance, which was caused by the interaction of the single disk resonance and a (1 0) grating resonance. Annealing for a short duration lowered the d/p ratio from 0.5 to 0.4, and led to smoothening of the disk surfaces and growth of gold grains, resulting in lower ohmic and radiative losses and doubling of the Q-factor of the resonances. Finite element method (FEM) simulations were used to monitor this improvement in material parameters. Annealing for a longer duration disintegrated the nanodisk into several smaller particles while maintaining the overall periodicity of the array. While the plasmonic resonances of the experimentally investigated fragmented disks were basically destroyed, simulation predict that for larger periods fragmented nanodisk arrays (keeping the d/p ∼ 0.4) can exhibit extremely strong and sharp resonances whose Q-factor increases more than 58.4 times compared to the unfragmented discs. In addition, simulations show a massive enhancement of the local electric field promising immense potential for surface enhanced Raman sensing.

Abstract
The present review analyses the research and development of piezoelectric supercapacitor (PSC)-based self-charging storage devices (SCSDs) over the last few years, with a bird’s-eye view of the prevailing trends and the outlook for the future. Piezoelectric materials, known for their ability to convert mechanical energy into electrical energy, have emerged as a key player in the development of next-generation supercapacitors with self-charging capability. The present review begins with elucidating the fundamental principles of piezoelectricity and piezoelectric generators vis-à-vis materials and properties as well as their integration into supercapacitor design. Advancements in fabrication techniques and the diversity of materials used have been discussed in detail with a focus on various characterization techniques. The review also addresses existing limitations, such as low energy transfer efficiency and material toxicity, as well as presenting strategies to overcome these hurdles and proposing avenues for future research and development.

Authors: Cai Xiumei , Yang Xuan , Wu Chengmao , Song Liping 
Published: September 2024

Abstract
Discrete memristive chaotic systems play a crucial role in information security, and chaotic synchronization form the bedrock of secure and confidential communication. To enhance the chaotic complexity of the Cubic map, we introduce a memristor-coupled Cubic hyperchaotic system by integrating a discrete absolute memristor model with the Cubic map. The dynamics are thoroughly investigated through attractor phase diagrams, bifurcation diagrams, SE complexity analysis, and diagrams illustrating the distribution of dynamic behaviors. Furthermore, we establish methods for chaos control and nonlinear feedback synchronization for the memristive Cubic map. Leveraging this feedback synchronization, we achieve encrypted transmission of digital images. Simulation results validate the feasibility and robust security of the proposed encrypted transmission scheme.
Stability and evolution of skyrmionium and skyrmions in a spherical shell

Published: September 2024

Abstract
The study of magnetic structures, particularly those with curved geometries such as spherical shells, has obtained significant interest due to their potential applications in data storage, spintronics, and other advanced technologies. However, the effects of material parameters, geometric dimensions, and magnetic fields on the equilibrium and induced behaviors of skyrmions remain largely unresolved. Here, based on micromagnetic simulations, we firstly investigate the influence of spherical shell dimensions, magnetic anisotropy, exchange interaction, and Dzyaloshinskii–Moriya interaction on the magnetic states of spherical shells. We find that curvature effects become more pronounced with increasing thickness and decreasing radius, providing evidence for the role of curvature-induced DMI-like interactions in skyrmion formation. Additionally, we observe that applying a magnetic field to the spherical shell induces behaviors similar to those in disks, including the topological transition between skyrmionium and skyrmion states, the annihilation of skyrmions, and polarity reversal. Our study aims to advance the understanding of magnetic phenomena in curved geometries and contribute to the development of novel magnetic devices.

Published: September 2024

Abstract
The group V–VI semiconductor material getchellite (crystalline AsSbS3) has garnered extensive attention due to its wonderful electronic and optical properties. The pressure engineering is one of the most effective methods to modulate crystal structure and physical properties of semiconductor materials. In this study, the structural behavior, optical and electrical properties of AsSbS3 under high pressure have been investigated systematically by in situ high-pressure experiments for the first time. The monoclinic structure of AsSbS3 remains stable up to 47.0 GPa without phase transition. The gradual lattice contraction with increasing pressure results in a continuous narrowing of the bandgap then leads to pressure-induced metallization of AsSbS3 at 31.5 GPa. Our research presents a high-pressure strategy for tuning the crystal structure and physical properties of AsSbS3 to expand its potential applications in electronic and optoelectronic fields.
