Published: January 2025

Context. Understanding the hydrogen content in Venus’ primordial atmosphere is crucial for comprehending the hydrodynamic escape process that shaped its atmospheric evolution. The hydrogen originated from two main sources: molecular hydrogen (H2) from the solar nebula and water vapor (H2O) from geological degassing. The precise proportions of these sources remain uncertain, leading to different hypotheses about Venus’ atmospheric history. However, a systematic exploration of the parameter space regarding the proportions of these sources has not yet been conducted.
Aims. This study aims to constrain the hydrogen content and its sources in Venus’ primordial atmosphere by conducting extensive numerical simulations of early atmospheric escape scenarios.
Methods. We developed an improved energy-limited hydrodynamic escape model, integrated with a 1D radiative-convective equilibrium atmospheric model, to simulate the early atmospheric escape on Venus. Using isotopic data of Ne and Ar from the current Venusian atmosphere, we constrained the contributions of nebula-derived and degassing-derived hydrogen. Our simulations have explored over 500 000 scenarios, varying the initial H2 and H2O compositions and considering different solar extreme ultraviolet (EUV) irradiation conditions.
Results. Our results, based on the isotopic ratios of 20Ne/22Ne, 36Ar/38Ar, and 20Ne/36Ar observed in Venus’ atmosphere, indicate that the primordial atmospheric water content was limited to less than 0.01 ocean equivalents of H2 (0.0004 wt%) and less than 1.4 ocean equivalents of H2O. This suggests that if Venus ever had a primary hydrogen-rich atmosphere, it was mostly lost before forming its secondary, H2O-rich atmosphere. Furthermore, our method can be applied to constrain the primordial atmospheric compositions of other terrestrial planets, providing insights into their evolutionary histories.

The TiO2-doped V2O5/FTO nanocomposite thin films were prepared on the FTO substrates by sol-gel method and post-annealing process, and the MSM structural devices based on the prepared films were fabricated by sputtering, photolithography and etching techniques. SEM, XRD, and XPS were respectively used to study the morphology, structure and composition of the film, and the electrical and optical regulations of the device were measured by using spectrophotometry and semiconductor parameter analyzer. In the temperature range of 20–360 °C, the maximum modulation amplitude of the TiO2-doped V2O5/FTO film in the 400–1600 nm band was 18.282% and the modulation of the V2O5/FTO film was increased by 9.663% after TiO2-doping. The resistance of the FTO/V2O5-TiO2/FTO device reduced by 3–4 orders of magnitude by comparing with the FTO/V2O5/FTO device. The FTO/V2O5-TiO2/FTO device underwent semiconductor-metal state transition (SMT) around 259.91 °C. Under the applied voltage of 0–5 V, the maximum transmittance variations could reach 8.821%, 7.174% and 11.540% in 400–1600 nm band at the temperature of 20 °C, 40 °C and 80 °C, respectively. The outstanding optical and electrical regulation properties and the favorable cycling stability make the nanocomposite film expected to be applied in the field of optoelectronic devices.

Published: January 2025

AbstractPatellar tendon rupture (PTR) is a rare and severe postoperative complication of total knee arthroplasty (TKA). Even rarer is the intraoperative occurrence of PTR during TKA. PTR is a major complication as it can lead to chronic disability, functional limitations, and postoperative morbidity. Therefore, surgical repair of the intraoperative PTR is typically pursued through one of the following three methods: (i) primary repair with direct suturing; (ii) direct suturing with cerclage augmentation, and (iii) direct suturing with either autograft or synthetic graft augmentation. In the case of an incomplete tear, direct repair with suture anchors for distal tears, and end-to-end repair with/without synthetic graft augmentation for mid-substance and proximal tears, is recommended. In the case of complete tears, if adequate tissue is present, direct repair with extensor mechanism reconstruction should be performed, regardless of the location of the tear. Furthermore, for complete tears with defective tissue, extensor mechanism reconstruction should be performed using mesh or allograft augmentation, regardless of the location of the tear. This review aims to provide a comprehensive and thorough overview of the prevention, diagnosis, management, and outcomes of intraoperative extensor mechanism injuries during TKA.
Countering populism through emotive transformation: political performances during Taiwan’s 2021 COVID outbreak
Authors: Lo Ming-Cheng M. , Hsieh Shinyi 
Published: January 2025

AbstractScholars have analyzed how structural forces and cultural factors contribute to populism, but relatively little research has been devoted to documenting or theorizing counter-populism. This study asks: how does counter-populist performance become successful? We engage the literatures of populism, political performance, and hope, and conduct a case study of the 2021 COVID outbreak in Taiwan. Drawing on a qualitative analysis of 313 newspaper reports, we find that the Taiwanese government’s counter-populist efforts succeeded through transforming an emotive context of anger into one featuring hope—a process we term “emotive transformation.” We identify three facilitating mechanisms: the enactment of key elements of hope (agency, valid pathways, support from allies, and tangible outcomes); the timely inclusion of bipartisan or nonpartisan participants; and strong collective effervescence. Our study contributes to theorizing counter-populism and helps address the “Atlantic bias” in studies of populism.
Bridges across regions: the effects of Euro-Atlantic and Indo-Pacific cooperation on European security architectures
Authors: Grgić Gorana 
Published: January 2025

AbstractThis article examines the evolving landscape of European security cooperation with partners outside the Euro-Atlantic theater, focusing on the Indo-Pacific region. Prior to Russia’s full-scale invasion of Ukraine, European threat assessments prompted a re-evaluation of security policies, highlighting the importance of partnerships with like-minded countries. This shift has introduced complexities in European security dynamics, including updated bilateral engagements, novel minilateral formats, and some revisions to multilateral cooperation. This article critically assesses who, how, and in what way is organizing these new and updated security partnerships. Focusing on the phenomenon of cross-regional cooperation, the article examines fundamental questions related to the organization of European security. First, the article investigates the beneficiaries of European security initiatives (who benefits) and the extent to which European actors have a clear vision for such engagements. Namely, whether they have been acting as architects, bricoleurs, agnostics, or spoilers. It also examines the mechanisms employed to ensure security and identifies the threats targeted by these measures (how), particularly regarding collaboration among multiple revisionist states. Lastly, the article explores how existing and newly formed cooperation modes impact European security architecture (in what way), arguing that some contribute to the existing “shopping malls” and others to the “tree houses.”

Published: January 2025

Abstract
We investigate the electronic properties of nanoribbons made out of monolayer Lieb, transition, and kagome lattices using the tight-binding model with a generic Hamiltonian. It allows us to map the evolutionary stages of the interconvertibility process between Lieb and kagome nanoribbons by means of only one control parameter. Results for the energy spectra, the density of states, and spatial probability density distributions are discussed for nanoribbons with three types of edges: straight, bearded, and asymmetric. We explore for different nanoribbon terminations: (i) the semiconductor-metallic transition due to the interconvertibility of the Lieb and kagome lattices, (ii) the effect of both nanoribbon width and inclusion of the next-nearest-neighbor hopping term on the degeneracy of the quasi-flat states, (iii) the behavior of the energy gap versus the nanoribbon width, (iv) the existence and evolution of edge states, and (v) the nodal spatial distributions of the total probability densities of the non-dispersive states.

-plug-and-play approach for MPI using a zero shot denoiser with evaluation on the 3D open MPI dataset
Authors: Gapyak Vladyslav , Rentschler Corinna Erika , März Thomas , Weinmann Andreas 
Published: January 2025

Abstract

Objective. Magnetic particle imaging (MPI) is an emerging medical imaging modality which has gained increasing interest in recent years. Among the benefits of MPI are its high temporal resolution, and that the technique does not expose the specimen to any kind of ionizing radiation. It is based on the non-linear response of magnetic nanoparticles to an applied magnetic field. From the electric signal measured in receive coils, the particle concentration has to be reconstructed. Due to the ill-posedness of the reconstruction problem, various regularization methods have been proposed for reconstruction ranging from early stopping methods, via classical Tikhonov regularization and iterative methods to modern machine learning approaches. In this work, we contribute to the latter class: we propose a Plug-and-Play approach based on a generic zero-shot denoiser with an

-prior. Approach. We validate the reconstruction parameters of the method on a hybrid dataset and compare it with the baseline Tikhonov, ART, DIP and the previous PP-MPI, which is a Plug-and-Play method with denoiser trained on MPI-friendly data. Main results. We derive a Plug-and-Play reconstruction method based on a generic zero-shot denoiser. Addressing (hyper)parameter selection, we perform an extended parameter search on a hybrid validation dataset we produced and apply the derived parameters for reconstruction on the 3D Open MPI Dataset. We offer a quantitative and qualitative evaluation of the zero-shot Plug-and-Play approach on the 3D Open MPI dataset with the validated parameters. Moreover, we show the quality of the approach with different levels of preprocessing of the data. Significance. The proposed method employs a zero-shot denoiser which has not been trained for the MPI reconstruction task and therefore saves the cost for training. Moreover, it offers a method that can be potentially applied in future MPI contexts.
Modal analysis of Doppler shift and strain time histories extracted from distributed fiber optic sensing data
Authors: Brewick Patrick T , Peña Francisco , Parker Allen R , Chan Hon M 
Published: January 2025

Abstract
While fiber optic sensing systems (FOSS) operate through a variety of technologies, optical frequency domain reflectometry (OFDR) has emerged as a means for distributed sensing, wherein a single fiber contains hundreds to thousands of sensing points along its length. Currently, most OFDR distributed sensing focuses on strain sensing; however, prior to deriving strain information, the changes in the carrier frequency of optical gratings can also be monitored. These changes in carrier frequency register as Doppler shifts, and this study explores treating these shifts like dynamic signals, e.g. time histories. Further, this study demonstrates that the Doppler shift time histories contain modal information distinct from strain measurements that can be similarly extracted through traditional modal analysis. Using experimental data from modal testing of a cantilevered plate, frequency-based modal identification is performed on both strain and Doppler shift time histories recovered from an OFDR-based distributed FOSS. The results reveal that Doppler shift time histories yield estimates of the slope mode shapes, as opposed to the strain mode shapes produced by the strain time histories, which can be used to recover displacement mode shapes through numerical integration. In addition, comparisons between the dynamic signals show that the Doppler shift time histories provide a greater number of identifiable modes with higher correlations to reference mode shapes than strain measurements.

Authors: Manjula M , Muthumari M , Viswanathan E 
Published: January 2025

Abstract
We report an extensive study on the structural and thermoelectric performance of the novel semiconducting binary type ATe2 (A = Mg,Be,Ca,Sr,Ba) earth abundant materials using Density Functional Theory (DFT) and semi-classical Boltzmann transport theory. The PBE-GGA exchange correlation potential method was used for electronic structure calculations within the framework of density functional theory. The structural stability of the materials was confirmed by ground state energy, formation energy and mechanical responses. The calculated lattice constants, energy band structures and density of states explain the nature of the materials and are agreed with previous experimental and theoretical works. According to our calculated results, we revealed a high figure of merit materials are CaTe2 and SrTe2 due to high Seebeck and electrical conductivity and low thermal conductivity values. Additionally, Slack’s equation was utilized to obtain low lattice thermal conductivity values. Our findings will serve as theoretical guidelines for future experimental and industrial applications both in cooling and heating.
Riemann–Hilbert approach to the higher-order Kaup-Newell equation on the half line
Authors: Yu 于 Hui 慧 , Zhang 张 Ning 宁 
Published: January 2025

Abstract
The higher-order Kaup–Newell equation is examined by applying the Fokas unified method on the half-line. We demonstrate that the solution can be expressed in relation to the resolution of the Riemann–Hilbert problem. The jump matrix for this problem is derived from the spectral matrix, which is calculated based on both the initial conditions and the boundary conditions. The jump matrix is explicitly dependent and expressed through the spectral functions, which are derived from the initial and boundary information, respectively. These spectral functions are interdependent and adhere to a so-called global relationship.

Authors: Bai 白 Nan 楠 , Feng 冯 Fan 帆 , Shao 邵 Mao-Zhong 茂忠 
Published: January 2025

Abstract
In this paper, we present an algebraic construction of the fused model for the ABJM spin chain by gluing two adjacent quantum spaces and two original auxiliary spaces. We prove the integrability of the fused model by demonstrating the validity of the Yang-Baxter equation. Owing to the regularity property of the fused R-matrix, we successfully construct the boost operator for the fused model and obtain the third-order charge accordingly. We also investigate the open spin chain Hamiltonian for the fused model and indicate the general common structures of the boundary terms which are further used to analyze the integrability of the flavored ABJM Hamiltonian.
Improvement of microstructure and mechanical properties for Al7075 aluminium reinforced with hybrid graphite and SiC particles via a combination of mechanical alloying and stir casting
Authors: Potisawang Charinrat , Talangkun Sukangkana , Ponhan Kowit 
Published: January 2025

Abstract
This research focuses on the fabrication of Al7075 composites reinforced with varying amounts of nano-sized SiC particles (1.0, 1.5, and 2.0 wt%) combined with 0.5 wt% graphite (Gr), employing a hybrid process of mechanical alloying and semi-solid stir casting. The study investigates the influence of SiC content, nanoparticle feeding method, and the role of Gr on the microstructures, mechanical characteristics, and machinability of the composites. Microstructural analysis revealed that integrating milled powders into the molten Al7075 alloy produced a uniform dispersion of nanoscale SiC particles within the α-Al matrix, avoiding the particle agglomeration observed with the conventional method. Higher SiC content resulted in finer grains and improved mechanical performance. The Al7075-0.5Gr-2.0SiC composite exhibited a 16% increase in hardness relative to the unreinforced Al7075 alloy. The inclusion of nanoscale SiC particles notably enhanced tensile strength, while the presence of Gr acted as a lubricant, improving surface roughness.

Published: January 2025

Abstract
Biomedical scaffolds are increasingly used in bone repair due to their exceptional ability to support cell growth and proliferation. This study developed a multifunctional poly(lactic-co-glycolic acid) (PLGA)/polyvinyl alcohol (PVA)/metronidazole coaxial electrospun nanofiber membrane to overcome the limitations of current bone tissue self-repair mechanisms. Optimization of the coaxial electrospinning parameters significantly improved the membrane’s overall performance. Mechanical property testing revealed that the tensile strength increased from 4.304 ± 0.079 MPa to 6.915 ± 0.032 MPa as the shell layer feeding rate was increased. Drug release studies demonstrated a marked reduction in the initial burst release of metronidazole as the shell layer thickness increased. The release amount decreased from 86% to 34% by the third hour, and the release continued over the course of one week. Furthermore, the in vitro release model transitioned from first-order kinetics to Peppas-Sahlin kinetics. In vitro studies confirmed that the metronidazole-loaded coaxial fiber membrane exhibited excellent biocompatibility, antibacterial properties, and osteogenic potential. In conclusion, PLGA/PVA controlled-release nanofiber membranes loaded with antibacterial drugs offer great promise for bone tissue regeneration therapies.

Abstract
In the present work, we utilized Au nanoparticles /electrochemically reduced graphene oxide ( AuNPs/ErGO) as a modifier of glassy carbon electrode to detect Hg(II) in surface water by a voltammetric method. The careful execution of the fabrication of AuNPs/ErGO on a glassy carbon electrode, achieved through the electrochemical reduction of graphene oxide (GO) and Au(III) solution using cyclic voltammetry, was a testament to our dedication and commitment. The modified electrode surface and the obtained materials were characterized by using a range of analytical techniques, including x-ray diffraction, Fourier Infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, energy-dispersive x-ray spectroscopy, elemental distribution maps, and electrochemical impedance spectroscopy. The results revealed the highly dispersed Au nanoparticles around 10–20 nm on the reduced graphene oxide matrix. Differential pulse-anodic stripping voltamtemtry (DP-ASV) was used for quantitative determinations, and the linear calibration curves were obtained in the Hg(II) concentration ranges of 2 to 15 ppb. The proposed DP-ASV approach offers a highly selective and sensitive method for Hg(II) determination with a limit of detection of 0.680 ppb. The study also meticulously addressed the common interfering species in aqueous solutions. Finally, the modified electrode was applied to sensitively determine Hg(II) in tap, lake, and river water samples with satisfactory results.

Published: January 2025

Abstract
Thermal cracking of SAE 40 lube oil contamination is a critical process for maintaining the efficiency and longevity of industrial machinery and automotive engines. This study investigates the mechanisms and outcomes of thermal cracking as a method to decompose and remove contaminants from lube oil (SAE40) and investigates the possibility of the use of solid coke produced as residue after the cracking process. The research also examines the optimal conditions for thermal cracking, including temperature ranges, heating rates, and the influence of catalysts. Analytical techniques such as thermogravimetry (TGA), Fourier-transform infrared spectroscopy (FTIR), and thermograms (DSC) are employed to characterize the chemical composition of the solid produced after treatment. This result reveals that the produced coke after the treatment demonstrates the resin capability, and it can be used as a binder or additive in lower temperature applications. This study underscores the potential of thermal cracking as an effective method for recycling contaminated lube oil, thereby contributing to sustainability and cost-efficiency in industrial maintenance practices.
