Published: December 2024

AbstractDue to road curvature and sensors’ limited field of view, as‐built highway curves would pose an operational challenge to the adaptive cruise control (ACC) system and its shared control. However, very few studies explored the adaptability of ACC system‐dedicated vehicles (V‐ACC) considering the vehicle‐road geometry interaction. Therefore, the objectives of this study are twofold: (i) investigating the implications of horizontal curves on V‐ACC dynamics and kinematics characteristics; and (ii) evaluating V‐ACC's adaptability from the safety, comfort, and speed consistency (S‐C‐S) aspects. To this end, a PreScan/CarSim/MATLAB/Simulink co‐simulation platform is established and it is validated by OpenACC database followed by designing many tests featuring circular curve radius (RC), desired speed (Vde), and clearance. The impact mechanism of geometric features was analysed by interpreting dynamics and kinematics characteristics along curves and critical features were further extracted by reference to S‐C‐S thresholds. The results show that: (i) either smaller RC or higher Vde causes those characteristics toward their S‐C‐S margins; (ii) neither sideslip nor rollover occurs, and speed consistency is good in most RC conditions; and (iii) drivers can follow the leading car comfortably with Vde = 40, 80–100 km/h but feel uncomfortable when Vde = 50–70 km/h and RC approaches its lower bounds.
Direct non-adiabatic modelling of gravito-inertial and Rossby tidally excited oscillations with the traditional approximation
Authors: Fellay L. , Dupret M.-A. 
Published: December 2024

Context. In recent years, the first detections of tidally excited stellar oscillations (TEOs) have been made in multiple star systems, offering new opportunities to study stellar physics and understand structural properties and stellar evolution. However, from a theoretical standpoint, numerous features in the observed oscillation spectrum cannot be explained, and current models cannot consistently treat the impact of stellar rotation on TEOs without using the Cowling approximation.
Aims. We aim to include the effect of the rotation in the modelling of TEOs and to study its consequences on the oscillation spectrum.
Methods. We developed a new methodology to include the Coriolis force in the modelling of TEOs through the traditional approximation but consistently treating the potential perturbation by iteratively solving the Poisson equation.
Results. By consistently including the Poisson equation, a new kind of mode coupling arises that we call ‘gravitational coupling’. Looking at the global oscillation spectrum, we find that the rotation greatly impacts the type of modes excited by the companion. In general, we find that the Rossby modes dominate the oscillation spectrum of TEOs.
Conclusions. It is particularly important to account for gravitational coupling at high spin parameters for the ℓ = 2, m = 2, and m = 0 oscillation modes. By assuming the modes are uncoupled, a simple and consistent treatment of the Poisson equation is possible. Including the effect of rotation in binary oscillation codes is necessary in order to accurately account for the impact of dynamical tides on the orbital evolution of binaries and planetary systems.

Context. On 2022 January 20, the Energetic Particle Detector (EPD) on board Solar Orbiter measured a solar energetic particle (SEP) event showing unusual first arriving particles from the anti-Sun direction. Near-Earth spacecraft separated by 17° in longitude to the west of Solar Orbiter measured classic anti-sunward-directed fluxes. STEREO-A and MAVEN, separated by 18° to the east and by 143° to the west of Solar Orbiter, respectively, also observed the event, suggesting that particles spread over at least 160° in the heliosphere.
Aims. The aim of the present study is to investigate how SEPs are accelerated and transported towards Solar Orbiter and near-Earth spacecraft, as well as to examine the influence of a magnetic cloud (MC) present in the heliosphere at the time of the event onset on the propagation of energetic particles.
Methods. We analysed remote-sensing data, including flare, coronal mass ejection (CME), and radio emission to identify the parent solar source of the event. We investigated energetic particles, solar wind plasma, and magnetic field data from multiple spacecraft.
Results. Solar Orbiter was embedded in a MC erupting on 16 January from the same active region as that related to the SEP event on 20 January. The SEP event is related to a M5.5 flare and a fast CME-driven shock of ∼1433 km s−1, which accelerated and injected particles within and outside the MC. Taken together, the hard SEP spectra, the presence of a Type II radio burst, and the co-temporal Type III radio burst being observed from 80 MHz that appears to emanate from the Type II burst, suggest that the shock is likely the main accelerator of the particles.
Conclusions. Our detailed analysis of the SEP event strongly suggests that the energetic particles are mainly accelerated by a CME-driven shock and are injected into and outside of a previous MC present in the heliosphere at the time of the particle onset. The sunward-propagating SEPs measured by Solar Orbiter are produced by the injection of particles along the longer (western) leg of the MC still connected to the Sun at the time of the release of the particles. The determined electron propagation path length inside the MC is around 30% longer than the estimated length of the loop leg of the MC itself (based on the graduated cylindrical shell model), which is consistent with the low number of field line rotations.

Published: December 2024

La relation entre la succion et la teneur en eau est un paramètre essentiel du comportement des sols non saturés. Différentes approches ont été utilisées pour modéliser ces courbes de rétention. La première se base sur des corrélations expérimentales (Brooks et Corey, 1966 ; van Genuchten, 1980 ; Gallipoli et al., 2003). La deuxième est la modélisation physique des sols non saturés : elle est utilisée pour cette étude. La forme de la courbe de rétention est une conséquence des hypothèses physiques. Cet article présente un modèle théorique basé sur la disposition de particules sphériques élastiques. Tout d’abord, un modèle adapté à un sol uniforme est présenté avec un seul diamètre de particules de sol. La deuxième étape étend l’utilisation du modèle aux sols gradués. Le modèle permet de traiter l’hystérésis entre le chemin d’humidification et le chemin de mouillage. Il utilise uniquement des paramètres physiques faciles à mesurer. Il est comparé à la courbe de rétention expérimentale de deux sols différents, le limon et le sable de Livet-Gavet en pâte et compacté à une énergie de 3,4 Optimum Proctor Normal (OPN). Le modèle montre des capacités prédictives intéressantes, sans aucune mesure de succion.

Purpose: This study aimed to evaluate the impact of Robotic-Assisted Total Hip Arthroplasty (RATHA) versus Conventional Total Hip Arthroplasty (CTHA) on perioperative blood loss, blood transfusion requirements, and early clinical outcomes. Methods: A prospective cohort study was conducted at a high-volume tertiary care center from January 2021 to January 2023. A total of 200 patients undergoing primary THA were equally divided into RATHA (using the MAKO SmartRobotics system) and CTHA cohorts. Propensity score matching adjusted for demographics and baseline characteristics, resulting in 172 matched patients. Primary outcomes included changes in perioperative hemoglobin, estimated blood loss (EBL), and transfusion rates. Secondary outcomes assessed were operative time, length of stay, and transfusion-related adverse events. Results: The RATHA group demonstrated significantly lower post-operative hemoglobin drops (2.49 ± 0.6 g/dL vs. 3.38 ± 1.0 g/dL; p < 0.001), reduced EBL on post-operative day 3 (1125.52 ± 361.2 mL vs. 1611.12 ± 501.4 mL; p < 0.0001), and lower transfusion rates (7.96% vs. 20.4%; p = 0.0175) compared to the CTHA group. Operative time was significantly shorter in the RATHA group (68.01 ± 8.7 minutes vs. 77.1 ± 10.5 minutes; p < 0.0001). All robotic cohort patients were discharged within 3 days, whereas 14% of CTHA patients required extended hospitalization. Conclusion: This study demonstrates that robotic-assisted total hip arthroplasty (RATHA) significantly reduces perioperative blood loss, hemoglobin drop, and blood transfusion rates compared to conventional total hip arthroplasty (CTHA). The observed decrease in operative time and hospital stay in the RATHA group further suggests that robotic assistance may enhance procedural efficiency and support faster patient recovery.

Published: December 2024

ResumenLa lesión medular espinal tiene una incidencia de 40 casos nuevos por millón de habitantes, siendo las regiones más afectadas la columna cervical y lumbar. En la lesión cervical, la función que más se demanda en recuperar es el control de la mano, pero cuando la lesión está por encima de C5, las opciones quirúrgicas tendinosas son muy limitadas, por lo que la transferencia nerviosa es la opción quirúrgica que nos queda. El determinar que transferencia va a ser útil y en qué momento realizarlo es el punto de discusión. Cada vez se va progresando más en esta línea, así como en la combinación del tratamiento tendinoso y nervioso.

ResumenPara evaluar la aplicabilidad de la técnica LANT (Local Anesthesia No Tourniquet) en la osteosíntesis de fracturas del radio distal (FRD), se diseñó un ensayo clínico aleatorizado que comparó los resultados a corto plazo entre pacientes tratados con anestesia local sin isquemia (LANT) y aquellos operados con anestesia locorregional (AR) y manguito de isquemia. Las principales variables del estudio fueron el dolor, la tumefacción y la satisfacción del paciente. También se analizaron el sangrado de la herida quirúrgica, la movilidad, la dificultad técnica percibida por el cirujano, la insuficiencia anestésica y las complicaciones.Entre diciembre de 2020 y 2021, se incluyeron 27 pacientes. Aquellos tratados con LANT presentaron menos dolor entre los días 10 y 15 tras la cirugía, así como menos sangrado durante el posoperatorio inmediato. 22 de los 27 pacientes del estudio requirieron sedación, y el 67% del grupo LANT necesitó dosis adicionales de anestesia local. Concluimos que LANT es una técnica viable para la osteosíntesis de FRD y podría ofrecer ciertos beneficios al evitar el uso del manguito de isquemia en casos seleccionados. Sin embargo, los autores del estudio recomiendan añadir anestesia local alrededor de la articulación radiocubital distal (ARCD) para mejorar el manejo del dolor durante las maniobras de reducción y destacan que la colaboración con un anestesiólogo fue imprescindible durante su estudio.

Published: December 2024

High-pressure synthesis of lutetium hydrides from molecular hydrogen (H2) and lutetium (Lu) is systematically investigated using synchrotron X-ray diffraction, Raman spectroscopy, and visual observations. We demonstrate that the reaction pathway between H2 and Lu invariably follows the sequence Lu ⟶ LuH2 ⟶ LuH3 and exhibits a notable time dependence. A comprehensive diagram representing the formation and synthesis of lutetium hydrides as a function of pressure and time is constructed. Our findings indicate that the synthesis can be accelerated by elevated temperature and decelerated by increased pressure. Notably, two critical pressure thresholds at ambient temperature are identified: the synthesis of LuH2 from Lu commences at a minimum pressure of ∼3 GPa, while ∼28 GPa is the minimum pressure at which LuH2 fails to transform into LuH3 within a time scale of months. This underscores the significant impact of temporal factors on synthesis, with the reaction completion time increasing sub-linearly with rising pressure. Furthermore, the cubic phase of LuH3 can be obtained exclusively through compressing the trigonal LuH3 phase at ∼11.5 GPa. We also demonstrate that the bandgap of LuH3 slowly closes under pressure and is noticeably lower than that of LuH2.

Published: December 2024

We have developed a built-in gasket for the Bridgman-type opposed-anvil high-pressure cell, featuring a PTFE (Teflon) capsule of ϕ 2.0 (1.5) × 2.5 mm3, filled with a liquid pressure-transmitting medium. This gasket, comprising a stainless-steel plane disk, a stainless-steel support ring, and pyrophyllite support gaskets, has enhanced the sample space height, allowed for precise adjustment of the anvil top area, and facilitated easy electrical insulation of lead wires. We calibrated the pressure by detecting phase transitions in Bi and Sn through resistivity measurements, achieving nearly hydrostatic pressure up to 9.4 GPa with this cell. Our analysis of the deformation of the gasket components under force has provided guidelines for effective pressurization.

Main text
International key comparison on luminous intensity was organized by the Asia Pacific Metrology Programme (APMP), identified as APMP.PR-K3.a, and carried out with coordination by National Metrology Institute of Japan (NMIJ-AIST) as the pilot laboratory. In total, 13 national metrology institutes (NMIs) participated in the comparison. The linkage to the key comparison reference value (KCRV) of luminous intensity scale was provided through the result of the CCPR key comparison, CCPR-K3.a (1999), by NMIJ-AIST and National Institute of Metrology, China (NIM). In the comparison, a group of luminous intensity standard lamps were used as transfer standard lamps. The comparison was organized as star-type comparison (Participant - Pilot - Participant). Luminous intensity scale of each participant was compared with the KCRV through the measurement results of the transfer standard lamps and associated uncertainties, and the relationship with the KCRV were evaluated to declare its international equivalence. All the data analyses were performed in accordance with the CCPR guidelines.
This report provides the overview of the comparison, including measurement procedure, transfer standard lamps, data analysis, measurement results of all the participant NMIs and their uncertainties. The final result of the comparison is given as the degree of equivalence (DoE) of the participants obtained based on the difference from the KCRV determined in CCPR-K3.a (1999) and their stated uncertainties.

Main text
A comparison of radiance temperature scales for clinical infrared ear thermometers have been performed successfully over the temperature range from 35.5 °C to 41.5 °C using one travelling blackbody in APMP. The radiance temperature of the travelling blackbody cavity has been compared directly to the standard blackbodies of the participating NMIs using ear thermometers with high resolutions and good short-term stabilities. There are some outliers in the results, but, in general, the radiance temperatures realized by the participant NMIs agree to well within ± 0.03 °C, which is agreeing with each other within the measurement uncertainties. The results also demonstrate comparable quality of the blackbody cavities recommended for the ear thermometer calibration in the ASTM, JIS, EN and CN standards. The results of this comparison can be used to underpin the Calibration and Measurement Capabilities (CMCs) of the participants, both for the calibration of ear thermometers and the ear thermometer blackbodies.

Clock synchronization and light-travel-time estimation for space-based gravitational-wave detectors
Authors: Niklas Reinhardt Jan , Hartwig Olaf , Heinzel Gerhard 
Published: December 2024

Abstract
Space-based gravitational-wave detectors, such as the Laser Interferometer Space Antenna (LISA), record interferometric measurements on widely separated satellites. Their clocks are not synced actively. Instead, clock synchronization is performed in on-ground data processing. It relies on measurements of the so-called pseudoranges, which entangle the interspacecraft light travel times (LTTs) with the clock desynchronizations between emitting and receiving spacecraft. For interspacecraft clock synchronization, we need to isolate the differential clock desynchronizations, i.e. disentangle the pseudoranges. This further yields estimates for the interspacecraft LTTs, which are required as delays for the laser frequency noise suppression via time-delay interferometry (TDI). Previous studies on pseudorange disentanglement apply various simplifications in the pseudorange modeling and the data simulation. In contrast, this article derives an accurate pseudorange model in the barycentric celestial reference system, complemented by realistic state-of-the-art LISA data simulations. Concerning pseudorange disentanglement, this leads to an a priori under-determined system. We demonstrate how on-ground orbit determinations, as well as onboard transmission and on-ground reception time tags of the telemetry data, can be used to resolve this degeneracy. We introduce an algorithm for pseudorange disentanglement based on a nonstandard Kalman filter specially designed for clock synchronization in systems where pseudorange measurements are conducted in different time frames. This algorithm achieves interspacecraft clock synchronization and LTT estimation with submeter accuracy, thus fulfilling the requirements of TDI.

Abstract
Quasicrystalline materials with piezoelectric effects show significant potential for advancing actuators, sensors and energy harvesters. In this paper, the free vibration characteristics of two-dimensional decagonal piezoelectric quasicrystal cylindrical shells (PQCSs) are investigated in the framework of symplectic mechanics system. By introducing an original vector and its dual variable vector as the fundamental unknowns, the governing equations are reduced into a set of low-order ordinary differential equations system, thus the free vibration analysis is transformed into an eigenvalue problem within the symplectic space. By using the symplectic mathematics, the exact solutions for free vibration of PQCSs are finally obtained and expanded as a series of symplectic eigensolutions. Finally, accurate natural frequency and analytical vibration mode shapes for arbitrary classical boundary conditions are obtained simultaneously. The accuracy of the obtained solutions is verified by comparing with existing results in open literature. In addition, the effects of geometrical parameters, temperature rise, external voltage and coupling fields on the natural frequency and vibration mode shapes are investigated in numerical examples. Results indicate that the phason field exhibits significant influences on the natural frequencies and cannot be neglected in free vibration analysis of PQCSs. Furthermore, all the results can be served as benchmarks for the development of new analytical and numerical approaches.
Numerical study on ionic wind from pin to mesh with hole configuration under DC negative corona discharge

Published: December 2024

Abstract
This study explores the enhancement of ionic wind generation efficiency by incorporating a central hole in the mesh electrode under DC negative corona discharge conditions. Using numerical analysis techniques such as drift-diffusion equations and the Poisson equation, the mechanisms driving ionic wind generation were extensively analyzed. The characteristic Trichel pulses of negative corona discharge were examined by monitoring the variations in current with changes in applied voltage and central hole diameter. Particle image velocimetry experiments validated numerical analysis, showing good agreement between experimental and numerical results. The introduction of a central hole in the mesh electrode significantly reduced pressure drop and increased ionic wind velocity, addressing common problems of decreased momentum and increased frictional loss in mesh electrodes. This modification allows the ionic wind to flow more freely through the mesh electrode, enhancing overall efficiency by mitigating energy losses typically associated with mesh structures. Additionally, the study found that ionic wind velocity increased with rising voltage, showing variations in maximum velocity depending on hole size. The results suggest that optimizing central hole size could enhance the efficiency of ionic wind generation devices in various applications.
