Context.Many galaxy clusters show diffuse cluster-scale emission in the form of radio halos, showing that magnetic fields and relativistic electrons are mixed in with the intracluster medium. There is in general agreement with the idea that the origin of radio halos is connected to turbulence generated during cluster mergers. Statistical studies of large samples of galaxy clusters in the radio band have the potential to unveil the connection between the properties of radio halos and the mass and dynamics of the host clusters.Aims.Previous studies were limited to massive clusters and were based on a small number of radio halos. The aim of this paper is to investigate the scaling relation between the radio power of radio halos and the mass of the host clusters at low frequencies and down to lower cluster masses.Methods.We analysed the clusters from the second catalogue ofPlanckSunyaev–Zel’dovich sources that lie within the 5634 deg2covered by the second Data Release of the LOFAR Two-meter Sky Survey. We derived the correlation between radio power and host cluster mass, and investigated the distribution of clusters without radio halos with respect to this correlation. We used X-ray observations to classify the dynamical state of clusters and investigated its effect on the power of radio halos.Results.Using different fitting methods, we found a correlation between the power of a radio halo at 150 MHz and the mass of its host cluster down to 3 × 1014 M⊙. For comparison with previous works, with the Bivariate Correlated Errors and intrinsic Scatter (BCES)Y|Xmethod, we obtained the slope of the correlationB = 3.55 ± 0.60 and the normalisationA = 1.1 ± 0.1. This correlation has a large scatter, part of which can be attributed to the different dynamical states of host clusters. We used two statistical tests to show that the distribution of clusters with and without (upper limits) radio halos in the mass–radio power diagram is not compatible with a single correlation and that it is also not compatible with clusters being uniformly distributed below the correlation.
The magnetic field of a magnetohydrodynamic disk wind: Water maser observations and simulations

Published: October 2023

Context. Although star-formation models predict that the magnetic field plays an important role in regulating disk-mediated accretion and launching and collimating protostellar jets, observations of the magnetic field close enough (within a few 100 au) to the forming stars are still sparse.
Aims. Our goal is to measure and model the magnetic field distribution in the disk wind of the young stellar object (YSO) IRAS 21078+5211.
Methods. We performed sensitive global very long baseline interferometry observations of the polarized emission of the 22 GHz water masers tracing individual streamlines of the magnetohydrodynamic (MHD) disk wind in IRAS 21078+5211. Our resistive-radiativegravito-MHD simulations of a jet around a forming massive star are able to closely reproduce the observed maser kinematics in the inner jet cavity.
Results. We measure a weak level of 0.3–3.2% of linear and circular polarization in 24 and 8 water masers, respectively. The detected polarized masers sample the direction and the strength of the magnetic field along five distinct streamlines within the inner 100 au region of the disk wind. Along the four streamlines at smaller radii from the jet axis (≤25 au), the sky-projected direction of the magnetic field forms, in most cases, a small offset angle of ≤30º with the tangent to the streamline. Along the stream at larger radii (50–100 au), the magnetic field is sampled at only three separated positions, and it is found to be approximately perpendicular to the streamline tangent at heights of ≈10 and 40 au, and parallel to the tangent at ≈70 au. According to our simulations, the magnetic field lines should coincide with the flow streamlines in the inner jet cavity. The small tilt in the magnetic field direction observed along the inner streams can be well explained by Faraday rotation, assuming a realistic low level of ionization for the molecular shell of the jet of namely ~10−2. The magnetic field amplitudes measured from maser circular polarization are all within a relatively small range of 100–700 mG, which is in good agreement with the simulation results and consistent with reduced magnetic diffusivity in the jet cavity owing to efficient shock ionization.
Conclusions. By comparing observations achieving sub-au linear resolution with source-specific simulations, this work presents a very detailed study of the gas kinematics and magnetic field configuration in the MHD disk wind associated with the YSO IRAS 21078+5211. The close correspondence between flow streamlines and magnetic field lines together with the relatively high strength of the magnetic field indicate that the magnetic field has a dominant role in the launch and collimation of the YSO jet.
Period bouncers as detached magnetic cataclysmic variables
Authors: Schreiber Matthias R. , Belloni Diogo , van Roestel Jan 
Published: October 2023

Context. The general prediction that more than half of all cataclysmic variables (CVs) have evolved past the period minimum is in strong disagreement with observational surveys, which show that the relative number of these objects is just a few percent.
Aims. Here, we investigate whether a large number of post-period minimum CVs could detach because of the appearance of a strong white dwarf magnetic field potentially generated by a rotation- and crystallization-driven dynamo.
Methods. We used the MESA code to calculate evolutionary tracks of CVs incorporating the spin evolution and cooling as well as compressional heating of the white dwarf. If the conditions for the dynamo were met, we assumed that the emerging magnetic field of the white dwarf connects to that of the companion star and incorporated the corresponding synchronization torque, which transfers spin angular momentum to the orbit.
Results. We find that for CVs with donor masses exceeding ∼0.04 M⊙, magnetic fields are generated mostly if the white dwarfs start to crystallize before the onset of mass transfer. It is possible that a few white dwarf magnetic fields are generated in the period gap. For the remaining CVs, the conditions for the dynamo to work are met beyond the period minimum, when the accretion rate decreased significantly. Synchronization torques cause these systems to detach for several gigayears even if the magnetic field strength of the white dwarf is just one MG.
Conclusions. If the rotation- and crystallization-driven dynamo – which is currently the only mechanism that can explain several observational facts related to magnetism in CVs and their progenitors – or a similar temperature-dependent mechanism is responsible for the generation of magnetic field in white dwarfs, most CVs that have evolved beyond the period minimum must detach for several gigayears at some point. This reduces the predicted number of semi-detached period bouncers by up to ∼60 − 80%.

AbstractTraumatic carotid artery dissection (TCAD) usually occurs after a direct cervical trauma or blunt trauma that causes hyperextension and excessive rotation of the neck. The most frequent presentation of TCAD is stroke, with 80% of patients developing a stroke in the first week after the trauma. Recent data indicate that symptoms start later in non-survivors (19.5 hours after trauma) compared with survivors (12.5 hours). In this case report, a young boy, 14 years-old, developed TCAD after he fell from his bike. He developed ischemic stroke symptomatology in the eighth day of hospitalization, with full recovery of symtoms after acetylsalicylic acid (AAS) administration. The use of antithrombotic medication is recommended, aiming for better neurological outcomes and prevention of stroke in TCAD patients, as highlighted by our case. However, the treatment recommendations are based on observational studies and expert opinion, owing to the lack of concrete data on the treatment of carotid artery blunt trauma. New studies and data are required to improve diagnosis and treatment of TCAD.

Authors: Marques Robinson Antonio Menegotto , Marques Adriana Hernandez , Marques Amanda Hernandez 
Published: October 2023

Abstract
Objective Intraoperative ultrasound (IOUS) is an imaging method that can be used in various neurosurgical procedures. It assists in the removal of brain tumors, hematomas, in the insertion of ventricular catheters, and in spinal and peripheral nerve surgeries. The original studies using IOUS were performed with devices that produced lower-quality images, generating little interest in their use. The introduction of ultrasound devices that yielded higher-quality images associated with a relative low cost and ease of use rendered IOUS attractive. Thus, we started using it in multiple neurosurgical procedures, studying its practicality, efficacy and limitations.
Materials and methods A retrospective case study on the use of IOUS in neurosurgery from August 2014 to December 2020 at a single institution, evaluating its practicality, efficacy and limitations.
Results A total of 127 IOUS scans were performed in 112 patients aged 19 to 83 (mean: 53.8) years: 106 scans of the brain, 4 of the spinal cord, and 2 of the peripheral nerves. Brain tumors were the majority, with 86 cases (67.8%). The IOUS was unsatisfactory in 9 cases (7.1%), and there were no cases of infection related to the IOUS.
Conclusion The IOUS is a dynamic, safe, and practical exam. It can be performed in a few minutes and repeated several times during the surgical procedure. It enables surgeons to observe the pulsation of tissues and vessels, the displacement of lumps in liquid collections, and to monitor the drainage of cysts and collections, in vivid, interactive and real-time images.
Declining population and GDP growth
Authors: Lianos Theodore P. , Pseiridis Anastasia , Tsounis Nicholas 
Published: October 2023

AbstractBusinesspeople and politicians seem to be afraid that population reduction will be accompanied by economic recession. In this paper we examine the experience of some countries of various sizes in which population has been declining and observe how GDP, GDP per capita, unemployment rate, and labour force participation rate are evolving during the period that population is declining. Using the pooled mean group (PMG) estimation method, we find that population decline can go hand in hand with growing GDP and increasing per capita GDP, and at the same time the labour participation rate may increase and unemployment may fall.
From the coast to the interior: global economic evolution patterns and mechanisms

AbstractIt is well established that nighttime light brightness value, which is measured from satellites, correlates with economic prosperity across the globe. Researchers have diverged over whether economic factors cluster in coastal areas or move to interior areas. By using nighttime light data and applying the random forest algorithm to measure the proportion of global “near regions” GDP, it was seen that global GDP decreased from 67.25% in 2000 to 63.02% in 2018. This research reveals that under the continuous promotion of economic globalization, there is still a spatial imbalance of economic development between global “near regions” and “far regions”; however, economic factors are gradually shifting to interior areas and forming a “coastal remoteness” evolution pattern. Within the intercontinental range, there are obvious differences in the evolution patterns and spatial structure of economic development between the sub-regions. The reduction of overseas transportation costs and diseconomies of scale are the primary reasons for the evolution of “coastal remoteness” in global economic development. Our findings can facilitate future policymaking and the management of global coastal and interior areas, as well as establish new horizons for relevant research topics within the context of land and marine-coordinated development.
Critical and controversial issues pertaining to the growth and properties of Cu2O in the context of energy conversion

Published: October 2023

Cu2O has been deposited on m-, r-, and a-Al2O3 by reactive sputtering of Cu using Ar with different contents of O2 followed by annealing under carefully optimized conditions at 500 °C under Ar:H2 in order to prevent the oxidation and reduction of the Cu2O layers, which have a cubic crystal structure and are bulk-relaxed. We find that the content of O2 influences the structural and optical properties of the Cu2O layers that exhibited a detailed spectral structure and distinct peaks at 2.75, 2.54, and 2.17 eV corresponding to the indigo, blue, and yellow direct gap transitions of Cu2O as observed by ultrafast pump–probe spectroscopy at room temperature. However, we also observed a transition at 1.8 eV that is related to the occurrence of states ∼0.4 eV below the conduction band minimum of Cu2O. We discuss the controversial origin of these states, which are usually attributed to donor-like oxygen vacancy states, and suggest that the origin of these states may be related to traps at the interfaces of CuO/Cu2O nanostructures, which is important in the context of energy conversion pertaining to solar cells and photocatalysis.
Cognate facilitation in single- and dual-language contexts in bilingual children’s word processing
Authors: Koutamanis Elly , Kootstra Gerrit Jan , Dijkstra Ton , Unsworth Sharon 
Published: October 2023

Abstract
We examined the extent to which cognate facilitation effects occurred in simultaneous bilingual children’s
production and comprehension and how these were modulated by language dominance and language context. Bilingual Dutch-German
children, ranging from Dutch-dominant to German-dominant, performed picture naming and auditory lexical decision tasks in
single-language and dual-language contexts. Language context was manipulated with respect to the language of communication (with
the experimenter and in instructional videos) and by means of proficiency tasks. Cognate facilitation effects emerged in both
production and comprehension and interacted with both dominance and context. In a single-language context, stronger cognate
facilitation effects were found for picture naming in children’s less dominant language, in line with previous studies on
individual differences in lexical activation. In the dual-language context, this pattern was reversed, suggesting inhibition of
the dominant language at the decision level. Similar effects were observed in lexical decision. These findings provide evidence
for an integrated bilingual lexicon in simultaneous bilingual children and shed more light on the complex interplay between
lexicon-internal and lexicon-external factors modulating the extent of lexical cross-linguistic influence more generally.
On the constitutional relevance of non‑discursive enlanguaged doings to sociomaterial practices
Authors: Gahrn-Andersen Rasmus 
Published: October 2023

Abstract
In expanding on the ‘dynamics first, symbols afterwards’ principle (Cowley
2009) of Distributed Language research, I propose that embodied linguistic competencies comprise the prerequisite for
human agents to engage in sociomaterial practices. I make the case that human practical activity is fundamentally ‘enlanguaged’
and that linguistic skills are not only trans-practical in the sense of enabling agents to engage in diverse activities across
practices but also that they constitute the basis for adult skill acquisition (see Dreyfus and
Dreyfus 1986) more generally. Specifically, I explore language-relative skills as the enablers of more diverse
activities than what is prescribed to them by Saussurean linguistic tradition i.e., the denotative relations intrinsic to
linguistic signs as well the rule-governed combinations of such signs into meaningful sentences.
On the problem of the classical limit for statistical characteristics of a quantum Coulomb plasma
Authors: Trigger S A 
Published: October 2023

Abstract
The general structure of the perturbation theory series for the thermodynamic potential of a system of electrons and point ions is discussed. In the classical limit, when Planck’s constant ℏ → 0, the particular terms of the perturbation theory series diverge due to the impossibility of maintaining of stability of a purely classical system of the opposite sign charges attracted to each other. At the same time, it is known that in a certain range of parameters, a thermodynamic potential that does not contain Planck’s constant is a good approximation. Such thermodynamic functions describes the experimental data well and corresponds to the molecular dynamics calculations of model quasi-Coulomb systems. It is shown that the transition to a purely classical description, which implies the limit ℏ → 0, is impossible, but the terms of the series containing ℏ are small for certain plasma parameters and can be discarded. This is the rationale explanation of using classical models and approximations to describe plasma in certain parameter ranges. On this basis, a hypothesis is formulated about the absence of a classical limit for all measurable physical properties (including kinetic characteristics) of the Coulomb model of plasma, in which point particles interact according to the Coulomb law and, therefore, there are no adjustable parameters.
Consensus analysis of chain star networks coupled by leaf nodes
Authors: Chen Jing , Zhou Ling , Sun Weigang 
Published: October 2023

Abstract
Coupled star networks coupled by hub nodes have attracted significant interest due to the interplay between their coupling forms and dynamics. This paper introduces a novel family of chain star networks that are connected via a small number of leaf nodes. The coherence of these star networks is quantified using the Laplacian spectrum. By leveraging the network structures, we calculate the characteristic polynomial of the Laplacian matrix and obtain an exact solution for network coherence in relation to network parameters. In addition, we explore the robustness of network coherence against variations in network parameters. Furthermore, we compare the coherence performance of coupled star networks across different coupling forms Our findings demonstrate that the networks coupled by leaf nodes exhibit better coherence.
Analytical solution of local fractal continuum traffic flow model
Authors: Pokhriyal Bhawna , Goswami Pranay , Kumar Kranti 
Published: October 2023

Abstract
This study developed a continuum traffic flow model with local fractional derivatives. This model overcomes the non-differentiable traffic parameters arising in vehicular traffic flow. The proposed model is solved using the local fractional Laplace variational iteration method (LFLVIM) and is well suited for analyzing the dynamical evolution of non-differentiable traffic density and speed function. Furthermore, the stability of the solution for the continuum model has also been discussed. Illustrative examples are also discussed to show the effectiveness of employing LFLVIM in the suggested model. Additionally, numerical simulations for each instance have been displayed. This research indicates that the utilized iterative approach is efficient and may be used to derive the non-differentiable solution to the proposed continuum traffic model.

The postulated cause-effect four-tensor equation, a relativistic generalisation for classical angular-impulse–angular-momentum variation equation dJ = Mdt, includes the Poinsot-Euler rotation (angular-impulse–angular-momentum variation) equation, Newton’s second law (linear-impulse–linear-momentum variation equation), and thermodynamics first law (work–energy equation). This four-tensor formalism is applied to describe three linear translation with rotation processes: a ring rolling on the floor by a horizontal force linear impulse and torque, fulfilling the rolling condition (mechanical energy conservation), a spinning ring placed on the ground until achieved the rolling condition (mechanical energy dissipation by friction), and a fireworks wheel ascending an incline (mechanical energy production by decreasing a thermodynamic potential).
Conservation laws, bound-state solitons and modulation instability for a variable-coefficient higher-order nonlinear Schrödinger equation in an optical fiber
Authors: Yang Sheng-Xiong , Wang Yu-Feng , Jia Rui-Rui 
Published: October 2023

Abstract
Under investigation in this paper is a variable-coefficient sixth-order nonlinear Schrödinger equation, which describes the propagation of attosecond pulses in an optical fiber. Based on Lax pair, infinitely-many conservation laws are constructed. With the aid of auxiliary functions, bilinear forms are derived. In addition, the one- and two-soliton solutions are obtained via the Hirota method. The influences of variable coefficients for soliton velocity and profile are discussed. Particularly, the interaction periods and soliton separation factor of bound-state solitons are analyzed. Finally, modulation instability is investigated. The reported results could be used to understand related soliton molecule and optical instability phenomena in nonlinear optics.
Conservation laws, Lie symmetries, self adjointness, and soliton solutions for the Selkov–Schnakenberg system
Authors: Ali Kashif , Seadawy Aly R , Rizvi Syed T R , Aziz Noor 
Published: October 2023

Abstract
In this article, we explore the famous Selkov–Schnakenberg (SS) system of coupled nonlinear partial differential equations (PDEs) for Lie symmetry analysis, self-adjointness, and conservation laws. Moreover, miscellaneous soliton solutions like dark, bright, periodic, rational, Jacobian elliptic function, Weierstrass elliptic function, and hyperbolic solutions of the SS system will be achieved by a well-known technique called sub-ordinary differential equations. All these results are displayed graphically by 3D, 2D, and contour plots.
