Speech Kinematics and Perioral Muscle Activity Are Influenced by Stroop Effects
Authors: Kriegel Zoe , Fullenkamp Adam M. , Whitfield Jason A. 
Published: January 2025

Purpose:
The current project aimed to examine the effects of two experimental cognitive–linguistic paradigms, the Stroop task and a primed Stroop task, on speech kinematics and perioral muscle activation.

Method:
Acoustic, kinematic, and surface electromyographic data were collected from the verbal responses of 30 young adult healthy control participants in choice response, classic Stroop, and primed Stroop tasks. The classic and primed Stroop tasks included congruent and incongruent trials. Across all three tasks, the set of possible responses was limited to the same three possible color words (red, green, and black) to facilitate performance comparisons between tasks.

Results:
Trials with ink–word incongruence in the Stroop tasks resulted in significantly higher muscle activation in the upper lip during response selection. In addition, a prime word within the Stroop task resulted in more spatial variation in lip + jaw movements for the spoken responses. These results were accompanied by the expected longer response times for incongruent trials in both classic and primed Stroop tasks.

Conclusions:
These findings may suggest that more central cognitive–linguistic interference processes may lead to inefficiencies in more peripheral speech motor control. Future research should investigate the pattern of these effects in older adults with and without motor speech disorders for research and clinical applications.

Published: January 2025

Context. Quasar outflows are key players in the feedback processes that influence the evolution of galaxies and the intergalactic medium. The chemical abundance of these outflows provides crucial insights into their origin and impact.
Aims. We determine the absolute abundances of nitrogen and sulfur and the physical conditions of the outflow seen in quasar 3C298.
Methods. We analyzed archival spectral data from the Hubble Space Telescope for 3C298. We measured the ionic column densities from the absorption troughs and compared the results to photoionization predictions made with the Cloudy code for three different spectral energy distributions (SEDs), including MF87, UV-soft, and HE0238 SEDs. We also calculated the ionic column densities of the excited and ground states of N III to estimate the electron number density and location of the outflow using the Chianti atomic database.
Results. The MF87, UV-soft, and HE0238 SEDs yield nitrogen and sulfur abundances at supersolar, solar, and subsolar values, respectively, with a spread of 0.4–3 times solar. Additionally, we determined an electron number density of log(ne)≥3.3 cm−3, and the outflow might extend up to a maximum distance of 2.8 kpc.
Conclusions. Our results indicate a solar metallicity within an uncertainty range of 60% that is driven by variations in the chosen SED and photoionization models. This study underscores the importance of the SED impact on determining chemical abundances in quasar outflows. These findings highlight the necessity of considering a wider range of possible abundances that span from subsolar to supersolar values.
Stationary Mean Field Games on networks with sticky transition conditions
Authors: Camilli Fabio , Berry Jules 
Published: January 2025

We study stochastic Mean Field Games on networks with sticky transition conditions. In this setting, the diffusion process governing the agent's dynamics can spend finite time both in the interior of the edges and at the vertices. The corresponding generator is subject to limitations concerning second-order derivatives and the invariant measure breaks down into a combination of an absolutely continuous measure within the edges and a sum of Dirac measures positioned at the vertices. Additionally, the value function, solution to the Hamilton-Jacobi-Bellman equation, satisfies generalized Kirchhoff conditions at the vertices.
On-chip cryogenic low-pass filters based on finite ground-plane coplanar waveguides for quantum measurements
Authors: Muragesh Prasad , Thalakulam Madhu 
Published: January 2025

Quantum technology exploits fragile quantum electronic phenomena whose energy scales demand ultra-low electron temperature operation. The lack of electron–phonon coupling at cryogenic temperatures makes cooling the electrons down to a few tens of millikelvin a non-trivial task, requiring extensive efforts on thermalization and filtering high-frequency noise. Existing techniques employ bulky and heavy cryogenic metal-powder filters, which prove ineffective at sub-GHz frequency regimes and unsuitable for high-density quantum circuits such as spin qubits. In this work, we realize ultra-compact and lightweight on-chip cryogenic filters based on the attenuation characteristics of finite ground-plane coplanar waveguides. These filters are made of aluminum on sapphire substrates using standard microfabrication techniques. The attenuation characteristics are measured down to a temperature of 500 mK in a dilution refrigerator in a wide frequency range of a few hundred kHz to 8.5 GHz. We find their performance is superior by many orders compared to the existing filtering schemes, especially in the sub-GHz regime, negating the use of any lumped-element low-pass filters. The compact and scalable nature makes these filters a suitable choice for high-density quantum circuits such as quantum processors based on quantum dot spin qubits.

Abstract
This article1 analyses the original contribution of the Franciscan missionary
Basilio Brollo (Ye Zunxiao 葉尊孝 or Ye Zongxian
葉宗賢, Gemona, 1648–Xi’an, 1704) to the description
of Chinese toponyms and geographically relevant terms included in his Dictionarium sinico-latinum (1694, 1699), regarded as one of the most noteworthy earliest dictionaries compiled by
foreign missionaries in China. The article first provides an overview of the list of toponyms included in the dictionary,
describing their Chinese, romanised, and Latin renditions. Secondly, it compares selected terms with the corresponding toponymic
occurrences in the Chinese sources Brollo used as references when compiling the manuscript. The article concludes with a
discussion of the lexicographical and lexicological efforts involved in this process, as well as the intercultural dialogue
involved in them, highlighting Brollo’s personal and original contribution to the description of 17th-century Chinese geographical
elements, with special reference to the terms related to the Chinese geographical regions where he lived and worked.
The moral Foreign Language Effect beyond the L2
Authors: Stańczykowska Zofia , Paradowski Michał B. 
Published: January 2025

Abstract
Bilinguals’ decision-making may be affected by the linguistic context, depending on whether the scenario to be
evaluated is presented in their first or second language. This phenomenon is known as the (moral) Foreign Language Effect
(FLe/MFLE). To the best of our knowledge, the present study is the first to investigate whether a difference can also be observed
between decisions taken by multilinguals in their second (L2) vs third languages (L3). Expectedly, akin to the L2 Status Factor
hypothesis, the results of a survey experiment showed no significant distinctions in scenario evaluations across non-native
languages, suggesting that the “foreign status” of these renders similar emotionality and/or exemption from social normativity.
The few nuances that do emerge are traceable to the specific scenarios used in FLe research.

Published: January 2025

Abstract
Molybdenum oxides with distinct structures and phases have shown unique properties that are of interest in many scientific and technological applications. However, the scalability to large area deposition and in particular the deposition of surfaces with specific topology, with a uniform and controlled structure still remains a challenge. In this work, a uniform MoO3 film with amorphous structure was achieved via electrospray deposition from fine particle dispersion in water. A high vapor pressure solvent was utilized for the progress of the deposition. As-deposited films with large thicknesses (

<

μ

m) show amorphous structures with a mean roughness lower than ∼32 nm. The deposited film was subsequently subject to thermal treatment with optimal thermodynamic parameters in order to modify the structure, the phase, the defect density and subsequently the electronic properties of the final structure. It is shown that a uniform coating layer with controlled structure and defect density can be achieved. This method facilitates the deposition of oxide layers on a variety of unconventional surfaces with large area as well as curved geometry.

Published: January 2025

Abstract
Color centers are promising single-photon emitters owing to their operation at room temperature and high photostability. In particular, using nanodiamonds as a host material is of interest for sensing and metrology. Furthermore, being a solid-state system allows for incorporation to photonic systems to tune both the emission intensity and photoluminescence (PL) spectrum and therefore adapt the individual color center to desired properties. We show successful coupling of a single nanodiamond hosting silicon-vacancy color centers to a plasmonic double bowtie antenna structure. To predict the spectrum of the coupled system, the PL spectrum of the silicon vacancy centers was measured before the coupling process and convoluted with the antenna resonance spectrum. After transferring the nanodiamond to the antenna the combined spectrum was measured again. The measurement agrees well with the calculated prediction of the coupled system and therefore confirms successful coupling.

The study focuses on different combinations of linear, nonlinear, and constant terms It primarily investigates the role of multi-order state variables and their application to chaotic system models of varying dimensions. Firstly, by simulating a three-dimensional chaotic system, the paper analyzes how different combinations of nonlinear terms and initial conditions affect the system's chaotic behavior. Secondly, it evaluates the chaotic characteristics of a four-dimensional system, combining nonlinear terms with unknown parameters, using tools such as Lyapunov index diagrams, sample entropy, and dynamic trajectory plots. Finally, the paper integrates the constructed chaotic system with chaotic mapping to develop a two-level key chaotic image encryption system, thoroughly assessing its security and resistance to interference.
A nanophotonic structured resonators for GaInAsSb photocathodes with high electron collection rates

Published: January 2025

Abstract
GaSb-based nanopillar arrays photocathodes have great potential in fields such as thermal photovoltaic systems, solar cells, and low light night vision due to their high long-wave sensitivity, good stability, and low cost. However, the characteristic that the electrons emitted from its side are easily to be captured by the adjacent units results in a generally low net quantum efficiency. We design a GaInAsSb NPAs photocathode with nanopillars and wafers made of the same material. By adjusting the height of the pillar, we can achieve changes in the cathode emitter, which can be directed to achieve high-efficiency photocathodes according to application scenarios. Using FDTD method, the influence of NPA surface density on the performance of different emitter cathodes was simulated. In addition, we investigated the effects of incident angle and external electric field on the emission performance of the cathode. The results indicate that there is an optimal incident angle that allows the wafer to achieve an EQE close to 18%, while the external electric field enhances the EQE of the nanopillar. The work improves the net efficiency of GaSb-based photocathodes, which has guiding significance for the research and development of high-efficiency infrared photocathodes.
Effects of Sc and Zr on the phase point defects of the three major intermetallic phases in Al-Zn-Mg-Cu alloys from first-principles calculations
Authors: Xiao Yao , Liu Jia , Shi Yan 
Published: January 2025

Abstract
In the Al-Zn-Mg-Cu alloys formed by Laser powder bed fusion( L-PBF ), the elements Sc and Zr are of great importance for the strengthening and toughening properties. The purpose of this study is to investigate the effect of the presence of Sc and Zr on the stability of the phase structure in an Al-Zn-Mg-Cu alloys. First-principles calculations have been used to analyse the influence of Sc and Zr on the mechanical properties of the primary strengthened precipitated phase in Al-Zn-Mg-Cu alloys. The elastic modulus and electronic structure of three main metallic phases containing two types of point defects (Scx, Zrx) have been calculated. Research has demonstrated that the plastic properties of some point defects are improved by the occupation of Sc and Zr elements. Among them, Al2CuMg and MgZn2 are strongly affected by Sc occupation, and Al2Cu are strongly affected by Zr occupation. Zrx-type point defects are more stable than Scx-type point defects in Al2Cu, MgZn2 and Al2CuMg. The charge density distribution near the point defect of Scx and Zrx is higher than the pure phase, and the charges near Scx and Zrx tend to aggregate in a particular direction. In summary, this study reveals the influence mechanism of the intrinsic modification of the main phase point defects of Sc and Zr on the mechanical properties is revealed by the first-principles calculation method, which provides a theoretical basis for the composition design and optimisation of Al-Zn-Mg-Cu alloys with Sc and Zr addition.
Remaining useful life prediction of lithium-ion battery based on AConvST-LSTM-Net-TL
Authors: Li Zihan , Li Jiaxi , Wang Xiang , Zhang Canwen , Nie Lei 
Published: January 2025

Abstract
The accurate prediction of the Remaining Useful Life (RUL) of lithium-ion batteries can significantly enhance the safety and reliability of these batteries, thereby reducing operational risks. However, numerous existing methodologies operate under the assumption that both training and testing data adhere to the same distribution pattern, hindering the application of successful laboratory-based models to different target batteries. Hence, this study introduces a transfer learning model for predicting lithium-ion battery life, utilizing an attention mechanism-driven convolutional neural network (ACNN) in conjunction with a spatiotemporal Long Short-Term Memory network (ST-LSTM). Initially, the deep charging process data is leveraged for battery capacity estimation, where a Generalized Additive Model (GAM) is employed to delineate the nonlinear trend of battery capacity decay and characterize the capacity degradation. Following feature extraction, the Maximum Mean Discrepancy (MMD) value is computed to assess the distribution disparity between the two domains. Subsequently, the AConvST-LSTM-Net computes capacity estimations, loss functions for both source and target domains, merging these with the MMD value to formulate a comprehensive loss function. In conclusion, by employing transfer learning, the refined model is adapted to the target domain dataset, enabling the accurate prediction of the RUL of lithium-ion batteries. This approach is validated using the NASA lithium-ion battery dataset and the National Big Data Alliance for New Energy Vehicles (NDANEV), demonstrating the superior accuracy and robustness of the AConvST-LSTM-Net-TL model in comparisn to other prediction methods.
Twin stars in General Relativity and Extended Theories of Gravity
Authors: Lope-Oter Eva , Wojnar Aneta 
Published: January 2025

Abstract
We explore gravity-independent equations of state for neutron stars, particularly focusing
on twin stars. Twin neutron stars refer to a theoretical phenomenon in which two neutron stars
with the same mass exist in different stable configurations. Examining four categories, we
emphasize their behavior in both General Relativity and Palatini gravity. Additionally, we discuss
a subcategory of type I, which, in the context of General Relativity, does not exhibit twin star
phenomena, yet demonstrates this phenomenon in modified gravity. Furthermore, we briefly address
challenges associated with the negative trace of the energy-momentum tensor, prevalent in
both theories.
Dark matter-radiation scattering enhances CMB phase shift through dark matter-loading
Authors: Ghosh Subhajit , Ho Daven Wei Ren , Tsai Yuhsin 
Published: January 2025

Abstract
A phase shift in the acoustic oscillations of cosmic microwave background (CMB) spectra is a characteristic signature for the presence of non-photon radiation propagating differently from photons, even when the radiation couples to the Standard Model particles solely gravitationally. It is well-established that compared to the presence of free-streaming radiation, CMB spectra shift to higher ℓ-modes in the presence of self-interacting non-photon radiation such as neutrinos and dark radiation. In this study, we further demonstrate that the scattering of non-photon radiation with dark matter can further amplify this phase shift. We show that when the energy density of the interacting radiation surpasses that of interacting dark matter around matter-radiation equality, the phase shift enhancement is proportional to the interacting dark matter abundance and remains insensitive to the radiation energy density. Given the presence of dark matter-radiation interaction, this additional phase shift emerges as a generic signature of models featuring an interacting dark sector or neutrino-dark matter scattering. Using neutrino-dark matter scattering as an example, we numerically calculate the amplified phase shift and offer an analytical interpretation of the result by modeling photon and neutrino perturbations with coupled harmonic oscillators. This framework also explains the phase shift contrast between self-interacting and free-streaming neutrinos. Fitting models with neutrino-dark matter or dark radiation-dark matter interactions to CMB and large-scale structure data, we validate the presence of the enhanced phase shift, affirmed by the linear dependence observed between the preferred regions of the sound horizon angle θ

s
and interacting dark matter abundance. An increased θ

s
and a suppressed matter power spectrum is therefore a generic feature of models containing dark matter scattering with abundant dark radiation.

Published: January 2025

Abstract
Fiber scrambling is integral to high-precision calibration systems for radial velocity (RV) measurements, crucial in the quest for exoplanet discovery. Coherent light sources, like laser frequency combs, often induce laser speckles, a form of modal noise, which can result in spectra calibration errors. The starlight collected in astronomical observations is often polychromatic light. This study investigates the speckle-like mode noise generated under incoherent light, identifying a clear correlation between fiber length and the intensity of this noise. Remarkably, experiments using LED illumination showed that fibers shorter than 2 m exhibit significant speckle-like noise, manifesting as distinctive ripple-like structures, a newly identified phenomenon referred to as modal patterns. Mitigation techniques, including squeezing and vibrating methods, can reduce contrast and suppress modal patterns effectively. To further enhance scrambling performance, a novel fiber scrambling approach, the compound scrambler, is proposed. This design integrates laser polishing, thermal heating, and fiber tapering techniques to enhance near-field uniformity. Utilizing a combination of non-circular and graded index fibers, the compound scrambler achieves notable improvements in scrambling gain (SG). A refined nondestructive fabrication method, leveraging the superior scrambling effect of non-circular fibers and the efficiency of adiabatic taper structures, achieves a high SG of 1064. These findings contribute to advancing high-precision spectrograph design, offering practical solutions to enhance RV measurement accuracy. The compound scrambler's integrity and modular design promise stability, longevity, and scalability, holding immense potential for astronomical instrumentation.
Shear viscoelasticity in anisotropic holographic axion model
Authors: Li Wei-Jia , Kuang Xiaomei 
Published: January 2025

Abstract
In this work, we investigate the shear elasticity and the shear viscosity in a simple holographic axion model with broken translational symmetry and rotational symmetry in space via the perturbation computation. We find that, in the case of spontaneous symmetry breaking, the broken translations and anisotropy both enhance the shear elasticity of the system. While in all cases, the broken symmetries introduce a double suppression on the shear viscosity, which is in contrast to the result from the study of the p-wave holographic superfluid where the shear viscosity is enhanced when the rotational symmetry is broken spontaneously.
Topological transmission and topological corner states combiner in all-dielectric honeycomb valley photonic crystals

Published: January 2025

Abstract
We study the topological states (TSs) of all-dielectric honeycomb valley photonic crystals (VPCs). Breaking the space inversion symmetry of the honeycomb lattice by varying the filling ratio of materials for circular ring dielectric columns in the unit cell, which triggers topological phase transitions and thus achieves topological edge states (TESs) and topological corner states (TCSs). The results demonstrate that this structure has efficient photon transmission characteristics and anti-scattering robustness. In particular, we have found that changing the type of edge splicing between VPCs with different topological properties produces a change in the frequency of TCSs, and then based on this phenomenon, we have used a new method of adjusting only the type of edge splicing of the structure to design a novel TCSs combiner that can integrate four TCSs with different frequencies. This work not only expands the variety and number of unexplored TCSs that may exist in a fixed photonic band gap and can be rationalized to be selectively excited in the fixed configuration. Our study provides a feasible pathway for the design of integrated optical devices in which multiple TSs coexist in a single photonic system.
