Binary neutron star merger offsets from their host galaxies
Authors: Gaspari N. , Stevance H. F. , Levan A. J. , Chrimes A. A. , Lyman J. D.
Published: October 2024

Aims. The locations of binary neutron star (BNS) mergers within their host galaxies encode the systemic kicks that these systems received in the supernova aftermath. We investigate how the galactic potential and the systemic kicks shape the offset distribution of BNS mergers with a case study of GW 170817 and its host NGC 4993.

Methods. We derived dynamical constraints on the host potential from integral field spectroscopy with Jeans anisotropic modelling. We evolved the trajectories of synthetic BNSs from the BPASS code in the galactic potential, using two different kick prescriptions to investigate how the observed offsets might differentiate between these two possibilities. The simulation was repeated after swapping the host potential with that of a dwarf galaxy, to test the effect of the potential on the offsets.

Results. The location of GW 170817 is entirely consistent with our predictions, regardless of large or small kicks, because the strong potential of NGC 4993 is only diagnostic of very large kicks. In galaxies of similar or greater mass, large offsets can constrain large kicks, while small offsets do not provide much information. In an old dwarf galaxy, on the other hand, small offsets can constrain small kicks, while large offsets would prevent host association.
Evaluating the gravitational wave detectability of globular clusters and the Magellanic Clouds for LISA
Authors: van Zeist Wouter G. J. , Nelemans Gijs , Zwart Simon F. Portegies , Eldridge Jan J.
Published: October 2024

We used the stellar evolution code BPASS and the gravitational wave (GW) simulation code LEGWORK to simulate populations of compact binaries that may be detected by the future space-based GW detector LISA. Specifically, we simulate the Magellanic Clouds and binary populations mimicking several globular clusters, neglecting dynamical effects. We find that a handful of sources should be detectable in each of the Magellanic Clouds, but for globular clusters the amount of detectable sources will likely be less than one each. We compared our results to earlier research and find that our predicted numbers are several dozen times lower than both the results from calculations that used the stellar evolution code BSE and take dynamical effects into account, and results from calculations that used the stellar evolution code SEBA for the Magellanic Clouds. Earlier research that compared BPASS models for GW sources in the Galactic disk with BSE models found a similarly sized discrepancy. We determine that this discrepancy is caused by differences between the stellar evolution codes, particularly in the treatment of mass transfer and common-envelope events in binaries: in BPASS mass transfer is more likely to be stable and tends to lead to less orbital shrinkage in the common-envelope phase than in other codes. This difference results in fewer compact binaries with periods short enough to be detected by LISA existing in the BPASS population. For globular clusters, we conclude that the impact of dynamical effects is uncertain based on the literature, but the differences in stellar evolution have an effect of a factor of 20 to 40 on the number of detectable binaries.
Machine learning methods for automated interstellar object classification with LSST
Authors: Cloete Richard , Vereš Peter , Loeb Abraham
Published: October 2024

Context. The Legacy Survey of Space and Time (LSST), to be conducted with the Vera C. Rubin Observatory, is poised to revolutionize our understanding of the Solar System by providing an unprecedented wealth of data on various objects, including the elusive interstellar objects (ISOs). Detecting and classifying ISOs is crucial for studying the composition and diversity of materials from other planetary systems. However, the rarity and brief observation windows of ISOs, coupled with the vast quantities of data to be generated by LSST, create significant challenges for their identification and classification.

Aims. This study aims to address these challenges by exploring the application of machine learning algorithms to the automated classification of ISO tracklets in simulated LSST data.

Methods. We employed various machine learning algorithms, including random forests (RFs), stochastic gradient descent (SGD), gradient boosting machines (GBMs), and neural networks (NNs), to classify ISO tracklets in simulated LSST data.

Results. Our results demonstrate that GBM and RF algorithms outperform SGD and NN algorithms in accurately distinguishing ISOs from other Solar System objects. RF analysis shows that many derived Digest2 values are more important than direct observables (right ascension, declination, and magnitude) in classifying ISOs from the LSST tracklets. The GBM model achieves the highest precision, recall, and F1 score, with values of 0.9987, 0.9986, and 0.9987, respectively.

Conclusions. These findings lay the foundation for the development of an efficient and robust automated system for ISO discovery using LSST data, paving the way for a deeper understanding of the materials and processes that shape planetary systems beyond our own. The integration of our proposed machine learning approach into the LSST data processing pipeline will optimize the survey’s potential for identifying these rare and valuable objects, enabling timely follow-up observations and further characterization.

The Cluster HEritage project with XMM-Newton – Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a programme to study a minimally biased sample of 118 galaxy clusters detected by Planck through the Sunyaev–Zeldovich effect. Accurate and precise mass measurements are required to exploit CHEX-MATE as an astrophysical laboratory and a calibration sample for cosmological probes in the era of large surveys. We measured masses based on the galaxy dynamics, which are highly complementary to weak-lensing or X-ray estimates. We analysed the sample with a uniform pipeline that is stable both for poorly sampled or rich clusters –using spectroscopic redshifts from public (NED, SDSS, and DESI) or private archives and dedicated observational programmes. We modelled the halo mass density and the anisotropy profile. Membership is confirmed with a cleaning procedure in phase space. We derived masses from measured velocity dispersions under the assumed model. We measured dynamical masses for 101 CHEX-MATE clusters with at least ten confirmed members within the virial radius r200c. Estimated redshifts and velocity dispersions agree with literature values when available. Validation with weak-lensing masses shows agreement within 8 ± 16 (stat.) ± 5 (sys.)%, and confirms dynamical masses as an unbiased proxy. Comparison with Planck masses shows them to be biased low by 34 ± 3 (stat.) ± 5 (sys.)%. A follow-up spectroscopic campaign is underway to cover the full CHEX-MATE sample.
Two stellar populations with different metallicities in the low-mass globular cluster Gran 5
Authors: Lim Dongwook , Chun Sang-Hyun , Lee Young-Wook , Chung Chul , Koch-Hansen Andreas J. , Hong Seungsoo
Published: October 2024

Context. With the increasing number of discoveries of globular clusters in the inner Milky Way, the need for spectroscopic confirmation and further investigation of their stellar populations and chemodynamical properties has become crucial.

Aims. Gran 5 is a newly reported low-mass globular cluster located close to the Galactic center, and it is thought to be an accreted object associated with the Gaia-Enceladus structure. This study aims to investigate the stellar populations of Gran 5 and their detailed chemical properties.

Methods. We performed high-resolution near-infrared spectroscopy on seven stars in the field of Gran 5 using IGRINS on the Gemini-South telescope.

Results. We identified six stars as cluster members and reveal that they are divided into two stellar populations with different metallicities, with mean [Fe/H] values of −0.76 dex and −0.55 dex, respectively. In addition, the chemodynamical properties of Gran 5 agree with those of in situ globular clusters.

Conclusions. Our findings represent the first detection of two stellar populations with different metallicities in a low-mass globular cluster. This suggests that the metallicity variation in Gran 5 may have arisen from processes different from those in other globular clusters with metallicity variation, or that it may have lost a substantial amount of its initial mass during its evolution.
Studying the X-ray absorption characteristics of Centaurus X-3 using nearly 14 years of MAXI/GSC data
Authors: Balu Ajith , Roy Kinjal , Manikantan Hemanth , Tamang Abhisek , Paul Biswajit
Published: October 2024

Context. Centaurus X-3 is a persistent high-mass X-ray binary with the long-term light curve from the source exhibiting orbit-to-orbit intensity variations with no apparent superorbital periodicity.

Aims. We used ∼13.5 years of MAXI/GSC data to study the long-term behaviour of X-ray absorption caused by the stellar wind from the companion star and any absorbing structures present in the binary.

Methods. We used orbital-phase-resolved spectroscopy to study the variation in the photoelectric absorption along the line of sight of the source for both the intensity-averaged data and intensity-resolved data after dividing all the data binned with orbital period into three intensity levels.

Results. We find an asymmetric variation in the photoelectric absorption along the line of sight across an orbit of the source. The orbital-phase-resolved spectra show a clear increase in photoelectric absorption after ϕorb ∼ 0.5, which deviates from a spherically symmetric stellar wind model. The flux of Cen X-3 shows significant variation between consecutive orbits. An intensity-resolved spectral analysis of the source was performed, followed by an intensity-resolved and orbital-phase-resolved spectral analysis, which showed that at the medium and high intensity levels, the orbital-phase-resolved photoelectric absorption is slightly asymmetric with respect to mid-phase (ϕorb = 0.5). The asymmetry is very pronounced at the lowest intensity level and cannot be explained by a spherically symmetric wind from the companion star.

Conclusions. The differences in the orbital phase-dependence of absorption for different intensity levels suggest that the presence of an accretion wake, photoionization wake, or tidal stream is more prominent at a lower intensity level for Centaurus X-3 than at a higher intensity level.

Crossing the boundary between logic and context: The inspiration of Wittgenstein’s philosophy for the principled innovation of TESOL
Authors: Ye Yihao
Published: October 2024

The present study delves into the pedagogical implications of Ludwig Wittgenstein’s philosophical insights, particularly as they relate to the domain of Teaching English to Speakers of Other Languages (TESOL). In his seminal work, Philosophical Investigations, Wittgenstein introduces the notion that linguistic meaning is not immutable but is instead derived from the dynamic and context-specific ways in which language is employed – a concept he terms “language game”. This challenges long-standing, static conceptions of language and offers a novel lens through which to view cross-cultural communication within the realm of college English education. Within the sphere of cross-cultural discourse, interlocutors typically emerge from diverse cultural milieus, resulting in linguistic expressions and communicative practices that are profoundly shaped by their respective cultural norms. Wittgenstein’s model of language acquisition thus provides an intellectual foundation for academic institutions to focus on the impact of cultural variance on linguistic interaction, as well as to foster students’ acumen and adaptability in engaging with various linguistic registers across different situational contexts. This paper elucidates the distinctive aspects of Wittgenstein’s model of language acquisition and delineates its instructive value for enhancing cross-cultural communication competencies in college English, grounded in the theoretical underpinnings of his linguistic philosophy.

With the development of the film industry, its industrial chain has become increasingly comprehensive, and the degree of industrialization has risen significantly. Publicity and distribution have also become crucial components of the film industry. Douyin’s official accounts offer several advantages, catering to the self-media market and the public’s aesthetic preferences, aligning with the leisure habits of today’s youth and the contemporary trend of recommending films to young people via mobile devices. This study employs stratified sampling to select film samples on Douyin. It focuses on official Douyin channels that have achieved significant dissemination, specifically targeting the official self-media channels of films with the highest traffic in the fan list. A total of 10 official Chinese film self-media channels were selected. The study then identified the highest-rated subjects and representative short videos as the sample. Douyin’s official film accounts present both advantages and disadvantages. The emphasis is on how to effectively utilize these accounts while mitigating the negative effects of misuse. For the advantages, the focus should be on promoting and continually innovating without becoming complacent. For the shortcomings, the aim should be to address and avoid them proactively to prevent being marginalized by society.

This study asked high school students about their desire to share this account, their acceptance of advertisements, and their views on video creativity through questionnaires. According to the data, high school students are willing to share videos of Qikexingxing, and most of them will do. Second, most high school students do not care about the advertisements in the video of Qikexingxing, and some are even willing to let this account receive more advertisements. Third, they felt empathy for the content of a recent video of Qikexingxing. The results suggest that the bigger reason people share videos is that it has formed a way for high school students to socialize, solidifying friendships at a time. Interesting video content makes high school students do not resist advertisements, but at the same time, the account should also reasonably control the frequency of advertisement. The way how to keep Qikexingxing popular is to innovate and creating unique content.

An analysis of the reasons for Wu Sunfu's failure and success on three fronts in Midnight
Authors: Kong Yanwen , Wu Xinyun
Published: October 2024

This article starts with the causes of Wu Sunfu's three fronts, based on the specific content of the three fronts, analyzes the specific reasons for success and failure, and reveals the difficulties in the development of China's national industry in the early 1930s. On the first front, Wu Sunfu entrusted the task of quelling the labor movement to Tu Weiyue. Tu Weiyue quelled the labor movement by identifying Communist Party members among female workers and resolving conflicts with Qian Baosheng, Wu Weicheng, and others, victory was achieved on the first front, and the female workers resumed their work. On the second front, due to Wu Sunfu's persistent failure to solve the problem of insufficient funds, coupled with the outbreak of the original war, which resulted in unsold factory products, Yizhong Company gradually failed, and the second front was declared a failure. On the third front, Wu Sunfu fought against Zhao Botao with all his wealth, but his brother-in-law Du Zhuzhai betrayed and defected to Zhao Botao, directly leading to Wu Sunfu's failure in the bond market, and the third front was also declared a failure.
Investigations on the Hemostatic Potential of Physiological Body Fluids
Authors: Thaler Johannes , Tripisciano Carla , Nieuwland Rienk
Published: October 2024

Current blood coagulation models consider the interactions between blood, the vessel wall, and other tissues that expose tissue factor (TF), the main initiator of coagulation. A potential role of body fluids other than blood is generally not considered. In this review, we summarize the evidence that body fluids such as mother's milk saliva, urine, semen, and amniotic fluid trigger coagulation. The ability of these body fluids to trigger coagulation is explained by the presence of extracellular vesicles (EVs). These EVs expose extrinsic tenase complexes (i.e., complexes of TF and activated factor VII) that can trigger coagulation. Why these body fluids share this activity, however, is unknown. Possible explanations are that these body fluids contribute to hemostatic protection and/or to the regulation of the epithelial barrier function. Further investigations may help understand the underlying cellular and biochemical pathways regulating or contributing to coagulation and innate immunity, which may be directly relevant to medical conditions such as gastrointestinal bleeding and chronic inflammatory bowel disease.
Update on Tissue Factor Detection in Blood in 2024: A Narrative Review
Authors: Bonifay Amandine , Cointe Sylvie , Plantureux Léa , Lacroix Romaric , Dignat-George Françoise
Published: October 2024

Tissue factor (TF) is a transmembrane protein essential for hemostasis. Different forms of active TF circulate in the blood, either as a component of blood cells and extracellular vesicles (EVs) or as a soluble plasma protein. Accumulating experimental and clinical evidence suggests that TF plays an important role in thrombosis. Many in-house and commercially available assays have been developed to measure TF-dependent procoagulant activity or antigen in blood and have shown promising results for the prediction of disease outcomes or the occurrence of thrombosis events in diseases such as cancer or infectious coagulopathies. This review addresses the different assays that have been published for measuring circulating TF antigen and/or activity in whole blood, cell-free plasma, and EVs and discusses the main preanalytical and analytical parameters that impact results and their interpretation, highlighting their strengths and limitations. In the recent decade, EVTF assays have been significantly developed. Among them, functional assays that use a blocking anti-TF antibody or immunocapture to measure EVTF activity have higher specificity and sensitivity than antigen assays. However, there is still a high variability between assays. Standardization and automatization are prerequisites for the measurement of EVTF in clinical laboratories.
Alles Gluten, oder was? Weizenallergie – Zöliakie – Glutensensitivität
Authors: Schmidt Robert
Published: October 2024

Immer mehr Menschen meinen, Weizen bzw. Gluten nicht zu vertragen. Nicht nur Patienten mit gastrointestinalen Beschwerden, sondern auch mit Haut- und Gelenkbeschwerden oder unspezifischen Symptomen wie Müdigkeit, Abgeschlagenheit und Konzentrationsstörungen führen dies immer häufiger auf ihre Ernährungsgewohnheiten zurück. Dabei geht es natürlich nicht nur – aber oft – um das Thema Weizen bzw. Gluten. Da letztendlich nur die genaue Diagnose entscheidet, ob überhaupt und wenn ja wie konsequent eine bestimmte Diät einzuhalten ist, lohnt es sich, sich die 3 häufigen Beschwerdebilder Weizenallergie, Zöliakie und Glutensensitivität nochmals differenziert zu vergegenwärtigen. Bei der Weizenallergie handelt es sich um eine Überreaktion des Immunsystems, bei der Zöliakie um eine chronische Autoimmunerkrankung der Dünndarmschleimhaut, und der Verdacht auf eine Weizen- oder Glutensensitivität erhärtet sich, wenn die unspezifischen Beschwerden wie Reizdarmsyndrom nach Ausschluss einer Weizenallergie oder Zöliakie bestehen bleiben. Jedes Krankheitsbild erfordert eine unterschiedliche Auslassdiät von weizen- und glutenhaltigen Lebensmitteln.

Butterflies and bifurcations in surface radio-frequency traps: The diversity of routes to chaos
Authors: Rudyi S. , Shcherbinin D. , Ivanov A.
Published: October 2024

In the present article, we investigate the charged micro-particle dynamics in the surface radio-frequency trap (SRFT). We have developed a new configuration of the SRFT that consists of three curved electrodes on a glass substrate for massive micro-particles trapping. We provide the results of numerical simulations for the dynamical regimes of charged silica micro-particles in the SRFT. Here, we introduce a term of a “main route” to chaos, i.e., the sequence of dynamical regimes for the given particles with the increase of the strength of an electric field. Using the Lyapunov exponent formalism, typical Reynolds number map, Poincaré sections, bifurcation diagrams, and attractor basin boundaries, we have classified three typical main routes to chaos depending on the particle size. Interestingly, in the system described here, all main scenarios of a transition to chaos are implemented, including the Feigenbaum scenario, the Landau–Ruelle–Takens–Newhouse scenario as well as intermittency.
Pattern dynamics of networked epidemic model with higher-order infections
Authors: Guo Jiaojiao , Li Xing , He Runzi , Luo Xiaofeng , Guo Zun-Guang , Sun Gui-Quan
Published: October 2024

Current research on pattern formations in networked reaction–diffusion (RD) systems predominantly focuses on the impacts of diffusion heterogeneity between nodes, often overlooking the contact heterogeneity between individuals within nodes in the reaction terms. In this paper, we establish a networked RD model incorporating infection through higher-order interaction in simplicial complexes in the reaction terms. Through theoretical and numerical analysis, we find that these higher-order interactions may induce Turing instability in the system. Notably, the relationship between the size of the Turing instability range and the average 2-simplices degree within nodes can be approximated by a quadratic function. Additionally, as the average 2-simplices degree increases, the amplitude of the patterns exhibits three distinct trends: increasing, decreasing, and initially increasing then decreasing, while the average infection density increases consistently. We then provide a possible explanation for these observations. Our findings offer new insights into the effects of contact heterogeneity within nodes on networked pattern formations, thereby informing the development of epidemic prevention and control measures.
When multi-group selection meets mystery of cooperation in structured public goods games
Authors: Liu Xinyu , Yang Baosen , Hu Zhao-Long , Al-qaness Mohammed A. A. , Tang Changbing
Published: October 2024

Cooperation is the cornerstone of social stability and human development. In order to promote mutual cooperation among individuals, some researchers analyzed the important factors influencing individual behavior from the perspective of group selection, while others revealed the evolutionary mechanism of cooperative behavior in groups from the perspective of network reciprocity. However, group selection and network reciprocity actually work together and simultaneously drive individuals to cooperate with each other. Analyzing each mechanism in isolation provides an incomplete understanding of the interaction process. Inspired by this, we integrate the coupled effects of both group selection and network reciprocity on the behavior of individuals. We develop a structured public goods game model to study the evolution of individual cooperative behavior in multiple groups, where each individual can interact not only with intra-group individuals but also with inter-group individuals. Based on the fixed probabilities of multi-group selection, including intra-group and inter-group selection, we derive a general condition that promotes cooperation among individuals. Besides, we discuss the effects of the number of neighbors in a group, group size, and group size on the selection of cooperative behavior. Finally, we systematically compare our model with the well-mixed case, and the results show that a structured population enhances cooperation. Increasing the number of populations boosts the fixation probability of cooperation. To the best of our knowledge, this paper is the first to study the cooperative evolutionary dynamics of multi-group selection in structured populations through public goods games.

Sequestratum; instead, a combination of commonly occurring characters is used, including glaucescence in the hypanthium, funnel-shaped flowers <10 mm long and coriaceous leaves with dark drying petioles in contrast to a paler lamina. Species are distributed across East Asia, Malesia and Eastern Australia, with an apparent preference for nutrient-poor habitats. This checklist provides a foundation for future taxonomic revision of this clade, from an early branching node in the tree of life of the world’s largest tropical tree genus.

densities to the gas density. A variety of theoretical approaches are considered to determine the Vibrational-Vibrational (V-V) and Vibrational-Translational (V-T) rate coefficients. For the V-V kinetics, the simple form of an Harmonic Oscillator (sfHO), the Schwartz-Slawsky-Herzfeld (SSH) and the Forced Harmonic Oscillator (FHO) approaches are used. The SSH approach used in this study is an improved version based on the pure SSH approach. For the V-T kinetics, the sfHO, a fit function of the Semi-Classical (ffSC) calculations and a fit function of the Quasi-Classical Trajectory (ffQCT) calculations are used. The influence of these different approaches on the calculated temporal evolution profiles of the vibrational distribution functions (VDFs) within one pulse modulation cycle is revealed. It is observed that the use of these different approaches does not strongly affect the densities of the low vibrational levels (v < 5), whereas larger influences on the higher level densities are found. In addition, it is found that the simulated evolution of the VDFs are sensitive to the probabilities of the neutral wall reaction

A 1D micromechanics-based constitutive model for the thermoviscoelastic behavior of crosslinked semicrystalline shape memory polymers: numerical simulation and experimental validation
Authors: Zeng Hao , Shi Jiawen , Sun Huiyu , Gu Jianping , Xu Xiaotao , Song Linhui
Published: October 2024

The paper develops a 1D thermoviscoelastic constitutive model for the crystallization- and melting-induced one-way and two-way shape memory effects, as well as isothermal yielding behaviors, of crosslinked semi-crystalline polymers. A micromolecular chain model is proposed to characterize the transition between the amorphous and crystalline phases. Structural equations including a modified Eying model that combine phase transition and viscoelasticity equations are employed to predict the shape memory effects. An extensive experimental campaign has been carried out on poly (ethylene-co-vinyl acetate) based semi-crystalline elastomers to characterize the thermoviscoelastic temperature-stress-strain relations of the material under different loading and rate conditions. Some results guide the determination of the model parameters, while the rest validate the model capabilities. Comparisons with the experimental results show that the model can well reproduce the stress-strain-temperature responses, providing valuable insights for application development.

Published: October 2024

In the current work, the influence of oxygen and Mn2O3 impurity levels intervals 0.00 ≤ x ≤ 0.30 on various key properties such as electrical resistivity, superconducting, flux pinning ability, stabilization of ceramic system, and morphological properties of YBa2Cu3O7-y (Y-123) superconductor were examined by electrical resistivity, critical current density, and scanning electron microscopy (SEM), electron dispersive x-ray (EDX) measurements. The EDX test results indicated that all the Y-123 ceramics produced possessed different composition distributions on the sample surface. SEM photomicrographs also confirmed the improvement in the appearance of surface morphology and crystallinity quality of the YBa2Cu3O7-y system. Moreover, the development in the interaction quality between grains, pinning ability and strength quality of 2D coupled vortices was obtained with the oxygen ambient and optimum manganese impurity addition highly dispersing throughout the intra grain and inter-grain boundary couplings due to the increase in the artificial flux pinning nucleation sites in the Y-123 system. Thus, the best sample with the highest Jc value of 98 A/cm2 showed the most resistance to the applied magnetic field and current. Similarly, the same sample exhibited the greatest superconductive offset (98.320 K) and onset (100.504 K) temperatures values based on the development of the Cu-O coordination and stability of the crystal structure. In conclusion, this comprehensive study based on the analysis of oxygen and Mn2O3 impurity addition mechanism through the YBa2Cu3O7-y ceramic matrix may open a new and applicable field for advanced engineering, heavy industry technology and large-scale applications.

Published: October 2024

Lithium metal batteries, celebrated for their exceptional energy density, are promising for advanced energy storage. Nevertheless, the dynamic deformation of lithium metal during cycling often leads to the unchecked proliferation of lithium dendrites, compromising the solid electrolyte interface. This not only deteriorates cycle stability but also poses significant safety risks. In our approach, we develop a three-dimensional lithium-affinitive composite current collector, utilizing an external magnetic field. The lithiophilic nature of V2O5, coupled with the deformability support provided by nickel foam and the depth-enhancing influence of the magnetic field on lithium metal deposition, collectively contribute to a more controlled and stable lithium environment. Our findings indicate that this novel setup allows for a lithium metal deposition depth of up to 310 μm, markedly curtailing the growth of dendrites in successive cycles. Remarkably, batteries reassembled with this magnetically-enhanced, lithium pre-deposited current collector exhibits a coulombic efficiency of 98.3% after 320 cycles at 1 mA cm−2. Moreover, a full cell, equipped with LiFePO4, delivers an initial capacity of 158.4 mAh g−1 at 1 C.
Influence of interface voltage on charge build-up under high voltage
Authors: Zheng Lin , Holé Stéphane
Published: October 2024

The interface voltage appearing when two materials are brought into contact was measured with a high sensitive pressure-wave-propagation measurement setup in various low density and high density polyethylene samples coated either with aluminum or gold electrodes. The samples were then tested under high voltage (40 kV/mm) for 24 h to assess the correlation between interface voltage and charge injection at 22 °C. Aluminum electrodes induce a positive interface voltage toward the insulator favoring electron injection at the cathode while gold electrodes induce a negative interface voltage toward the insulator favoring hole injection at the anode. After the injections due to interface voltage, charges diffuse more easily in low density polyethylene that triggers a subsequent injection due to heterocharges buildup.
Complex dynamics in an atmospheric pressure glow discharge in helium: transition from stationary to periodic oscillatory, and fully chaotic states

Published: October 2024

This work deals with the numerical study of spontaneous temporal oscillations in an atmospheric pressure glow discharge (APGD) in helium. The transition of helium APGD from stationary to periodic oscillatory state through the Hopf bifurcation, and further from periodic to chaotic oscillations through period-doubling bifurcations is explored. The choice of the discharge and external electric circuits parameters is guided by the relevant experiments. The ballast resistance and supply voltage of the external circuit play the role of control parameters. The method is based on the stability analysis of stationary states of the discharge. The stability diagram predicting parameter regimes at which stable and oscillatory states of the APGD can be expected is obtained. The effects of the discharge parameters (such as the gas gap, secondary electron emission coefficient, and capacitance in the external electric circuit) on the bifurcation curve are identified. The Lorenz map and corresponding period-doubling bifurcation diagram characterizing transition to chaotic oscillations in helium APGD with an increase in the control parameter are derived. The value of the capacitance in the external circuit plays a critical role in the dynamical behavior of the discharge. Decreasing its value contributes to the dissipation/damping of the system, whereas increasing it enhances the irregular behavior of the system.
