Published: March 2023

AbstractSensory experiences in early development shape higher cognitive functions such as language acquisition in humans and song learning in birds. Zebra finches (Taeniopygia guttata) sequentially exposed to two different song ‘tutors’ during the sensitive period in development are able to learn from their second tutor and eventually imitate aspects of his song, but the neural substrate involved in learning a second song is unknown. We used fMRI to examine neural activity associated with learning two songs sequentially. We found that acquisition of a second song changes lateralization of the auditory midbrain. Interestingly, activity in the caudolateral Nidopallium (NCL), a region adjacent to the secondary auditory cortex, was related to the fidelity of second-song imitation. These findings demonstrate that experience with a second tutor can permanently alter neural activity in brain regions involved in auditory perception and song learning.
An accelerated distributed method with inexact model of relative smoothness and strong convexity
Authors: Zhang Xuexue , Liu Sanyang , Zhao Nannan 
Published: March 2023

AbstractDistributed optimisation methods are widely applied in many systems where agents cooperate with each other to minimise a sum‐type problem over a connected network. An accelerated distributed method based on the inexact model of relative smoothness and strong convexity is introduced by the authors. The authors demonstrate that the proposed method can converge to the optimal solution at the linear rate and achieve the optimal gradient computation complexity and the near optimal communication complexity, where κg denotes the global condition number. Finally, the numerical experiments are provided to validate the theoretical results and further show the efficacy of the proposed method.

Context. Galaxy shear and cosmic microwave background (CMB) lensing convergence cross-correlations contain additional information on cosmology with respect to auto-correlations. While remaining immune to certain systemic effects, these cross-correlations are nonetheless affected by the galaxy’s intrinsic alignments (IA). These effects may, in fact, be responsible for the reported low lensing amplitude of the galaxy shear × CMB convergence cross-correlations, compared to the standard PlanckΛCDM (cosmological constant and cold dark matter) cosmology predictions.
Aims. In this work, we investigate how IA affects the Kilo-Degree Survey (KiDS) galaxy lensing shear and Planck CMB lensing convergence cross-correlation and we compare it to previous treatments, both with and without IA taken into consideration.
Methods. We compared the marginalization over IA parameters and the IA self-calibration (SC) method (with additional observables defined only from the source galaxies) to demonstrate that SC can efficiently break the degeneracy between the CMB lensing amplitude, Alens, and the IA amplitude, AIA. We further investigated how different systematics affect the resulting AIA and Alens and we validated our results with the MICE2 simulation.
Results. We find that by including the SC method to constrain IA, the information loss due to the degeneracy between CMB lensing and IA is strongly reduced. The best-fit values are Alens = 0.84−0.22+0.22 and AIA = 0.60−1.03+1.03, while different angular scale cuts can affect Alens by ∼10%. We show that an appropriate treatment of the boost factor, cosmic magnification, and photometric redshift modeling is important for obtaining the correct IA and cosmological results.
Simulating dielectric spectra: A demonstration of the direct electric field method and a new model for the nonlinear dielectric response

Published: March 2023

We demonstrate a method to compute the dielectric spectra of fluids in molecular dynamics (MD) by directly applying electric fields to the simulation. We obtain spectra from MD simulations with low magnitude electric fields (≈0.01 V/Å) in agreement with spectra from the fluctuation–dissipation method for water and acetonitrile. We examine this method’s trade-off between noise at low field magnitudes and the nonlinearity of the response at higher field magnitudes. We then apply the Booth equation to describe the nonlinear response of both fluids at low frequency (0.1 GHz) and high field magnitude (up to 0.5 V/Å). We develop a model of the frequency-dependent nonlinear response by combining the Booth description of the static nonlinear dielectric response of fluids with the frequency-dependent linear dielectric response of the Debye model. We find good agreement between our model and the MD simulations of the nonlinear dielectric response for both acetonitrile and water.
Tradeoff between production and regulation functions of semi-arid rangelands
Authors: Mousavi Seyed Alireza , Mohammadi Kharaji Alimohammad , Soltani Saeed 
Published: March 2023

This study aimed to evaluate the tradeoffs between forage production and important regulation functions in the semi-arid rangelands of Ben county, Chaharmahal and Bakhtiari province, Iran. The value of the forage production service was estimated using market pricing method after measuring forage production within the plant types. Five regulation functions: (1) erosion control; (2) sediment control; (3) runoff regulation; (4) carbon sequestration; and (5) oxygen production were then quantified and valued by the replacement cost approach. The five regulating services included 92.9% of total economic value, and a significant difference between economic value of different plant types was recorded. However, results suggested that provisioning and regulating services were statistically correlated (R2 = 0.83), but the decrease in provisioning services due to the increase in grazing intensity was statistically more significant than the decrease in regulating services. For each one degree increase in the grazing intensity, the value of forage production and regulating services decreased by USD27.4 and USD245.2, respectively. This was a function of the large share of regulating services in total economic value.
Fluency in rendering numbers in simultaneous interpreting
Authors: Kajzer-Wietrzny Marta , Ivaska Ilmari , Ferraresi Adriano 
Published: March 2023

Abstract
There is general consensus among interpreting practitioners and scholars that numbers pose particular problems in
simultaneous interpreting. Adopting the view that fluency disruptions in interpreters’ renditions are signals of cognitive
processing problems, the authors aim to isolate those contextual and textual factors which increase the likelihood of disfluencies
when rendering numbers present in a source speech. In the reported study, we analyse data from the European Parliament Translation
and Interpreting Corpus (EPTIC): we focus on target-text segments whose corresponding source segment contains a number and we find
the best predictors of disfluencies by applying a generalized linear mixed model. Our approach is confirmatory and so the model
accounts for factors that have been suggested in earlier studies as being associated with interpreting fluency. These factors
include the nativeness of the original speaker, the type of number, the frequency of numbers in the same sentence, omission,
language pair and whether the text was originally delivered impromptu or read out, and at what pace. The outcomes suggest that
important predictors of disfluent renditions include omission, the frequency of numbers in a sentence and the type of number;
these can be said to contribute to interpreters’ cognitive load when they process numbers.

Assessment of indoor radon exposure in South Korea
Authors: Park Jaewoo , Kim Yong-Jae , Chang Byung-Uck , Kim Ji-Young , Kim Kwang Pyo 
Published: March 2023

Abstract
The objective of this study is to update the national and regional indoor radon concentrations in South Korea and assess indoor radon exposure. Based on the previously published survey results and the collected measurement data of surveys conducted since 2011, a total of 9271 indoor radon measurement data covering 17 administrative divisions are finally used for analysis. The annual effective dose from the indoor radon exposure is calculated using dose coefficients recommended by the International Commission on Radiological Protection. The population-weighted average indoor radon concentration was estimated to be a geometric mean of 46 Bq m−3 (GSD = 1.2) with 3.9% of all samples showing values exceeding 300 Bq m−3. The regional average indoor radon concentration ranged from 34 to 73 Bq m−3. The radon concentrations in detached houses were relatively higher than those in public buildings and multi-family houses. The annual effective doses to the Korean population due to indoor radon exposure were estimated to be 2.18 mSv. The updated values in this study might better represent the national indoor radon exposure level in South Korea because they contain more samples and cover a wider range of geographical areas than previous studies.
Characterisation of the soft tissue viscous and elastic properties using ultrasound elastography and rheological models: validation and applications in plantar soft tissue assessment

Published: March 2023

Abstract

Objective. The mechanical behaviour of soft tissue is influenced by its elastic and viscous characteristics. Therefore, the aim of this study was to develop a validated method to characterise the viscoelastic properties of soft tissues based on ultrasound elastography data. Approach. Plantar soft tissue was chosen as the tissue of interest, and gelatine-phantoms replicating its mechanical properties were manufactured for validation of the protocol. Both plantar soft tissue and the phantom were scanned using Reverberant shear wave ultrasound (US) elastography at 400–600 Hz. Shear wave speed was estimated using the US particle velocity data. The viscoelastic parameters were extracted by fitting the Young’s modulus as a function of frequency derived from the constitutive equations of the eight rheological models (four classic and their fractional-derivative versions) to the shear wave dispersion data. Furthermore, stress-time functions derived from the eight rheological models were fitted to the phantom stress-relaxation data. Main results. The viscoelastic parameters estimated using elastography data based on the fractional-derivative (FD) models, compared to the classic models, were closer to those quantified using the mechanical test. In addition, the FD-Maxwell and FD-Kelvin–Voigt models showed to more effectively replicate the viscoelastic behaviour of the plantar soft tissue with minimum number of model parameters (

R

= 0.72 for both models) . Hence the FD-KV and FD-Maxwell models can more effectively quantify the viscoelastic characteristics of the soft tissue compared to other models. Significance. In this study, a method for mechanical characterisation of the viscoelastic properties of soft tissue in ultrasound elastography was developed and fully validated. An investigation into the most valid rheological model and its applications in plantar soft tissue assessment were also presented. This proposed approach for the characterisation of viscous and elastic mechanical properties of soft tissue has implications in assessing the soft tissue function where those can be used as markers for diagnosis or prognosis of tissue status.
Plasma beta dependence of ion temperature gradient driven turbulence influenced by Shafranov shift
Authors: Niiro M , Ishizawa A , Nakamura Y , Maeyama S , Watanabe T-H 
Published: March 2023

Abstract
Plasma β dependence of ion temperature gradient (ITG) driven turbulence is investigated using gyrokinetic simulations, where β is the normalized pressure. In our β scan, self-consistent magnetohydrodynamic (MHD) equilibrium state is numerically calculated for each value of β. It is found that the influence of the Shafranov shift cancels out the electromagnetic stabilizing effect on the ITG mode, and the growth rate of the ITG mode is accordingly unchanged as β increases. As a result, the turbulent energy transport does not decrease with β as suggested by the

α

model (Ishizawa et al 2019 Phys. Rev. Lett.
123 025003). A significant difference from the

s
−
α

model is the increase of the energy transport with β. It is also found that the critical onset β value for the kinetic ballooning mode is significantly increased by the influence of the Shafranov shift. The cancellation of the electromagnetic stabilization by the Shafranov shift is explained by the decrease of magnetic drift frequency in the dispersion relation of electromagnetic ITG modes obtained by using a fluid approximation.
Suppression of stimulated Raman scattering in plasma by an ultra-wideband stochastic phase low-coherence laser
Authors: Yi S Y , Zhou H Y , Jiao J L , Wang H Z , Yan R , Zhang P D , Yin Y 
Published: March 2023

Abstract
Suppression of the stimulated Raman scattering (SRS) by a stochastic phase low-coherence laser (SPLL) in homogeneous plasma is investigated by theoretical analysis and one-dimensional particle-in-cell (PIC) simulation. A simple model is established, in which the SPLL is modelled as a combination of a monochromatic laser and a broadband laser. When the phase randomness increases, the bandwidth of the SPLL is broadened and the energy proportion of the monochromatic laser component is reduced. PIC simulation shows that the SPLL can effectively suppress SRS and hot electron generation. Various phenomena in the nonlinear process, such as the nonlinear frequency shift and the competition between forward-scattering and back-scattering modes, are explained in detail.

Published: March 2023

Abstract
An improved one-shot thermoplastic elastomer reinforced shape memory polymer (SMP) four-dimensional (4D) printing method for hybrid composite samples is proposed. Through the new reinforcement method of interlayer overlapping, the problem of inability to bond between polylactic acid (PLA) and thermoplastic polyurethane (TPU) is overcome, and the composite materials had excellent bonding properties. The feature of the improved manufacturing method is that the interface between PLA and TPU materials has continuous overlapping layers, and the boundary is wavy. Herein the complex multi-material space structure can be manufactured with a three-dimensional curved bonding surface. The shape memory and mechanical properties of the PLA/TPU hybrid composite sample are significantly improved via the improved printing method. The shape memory recovery rate of PLA/TPU hybrid composite samples are all over above 99.5%, which is close to complete recovery. The fastest recovery time is 40.61% shorter than the recovery time of the pure PLA sample, showing good shape memory cycle performance. The peak recovery force is 6.92 times higher than the recovery force of the pure PLA sample. The impact strength is 9.87 times higher than the impact strength of pure PLA sample. The composites 4D printing method can be utilized to process complex parts with excellent interfacial bonding properties, shape memory properties, and mechanical properties, which has a promising application prospect in the manufacturing of PLA-based sensors and actuators.

Abstract
The current research work reports the deposition of titanium-based multilayer coating (TiO/TiN) on Ni-Cr metallic alloy by a cathodic cage plasma processing technique using a titanium cage along with various combinations of gas mixtures i.e., N2-H2-Ar-O2 at 400 °C. The samples were characterized using x-ray photoelectron spectroscopy (XPS), which revealed the surface coating of TiO/TiN with Ti 2p at 462 eV, N 1s at 406 eV and O 1s at 530.09 eV. The x-ray diffraction (XRD) analysis confirmed the polycrystalline structure in the titanium-based coating with (111) for TiO/TiN and a crystallite size of 32 nm. Scanning electron microscopy (SEM) and x-ray dispersive spectroscopy (EDX) analysis of titanium-based TiO/TiN coatings was well correlated with the above mentioned findings. Corrosion analysis using polarization potentio-dynamic plots (PDP) and electrochemical impedance spectroscopy (EIS) revealed a significant improvement in various corrosion parameters like corrosion resistance, corrosion rate, surface porosity, corrosion protection efficiency, impedance, and charge transfer resistance. A spectrophotometer was used to measure the leaching of toxic ions (Ni, Cr) from untreated and treated specimens in NaCl electrolyte. Findings revealed efficient antibacterial activity of TiO/TiN-coated specimens against E. coli and S. aureus as compared to untreated samples. This work will be helpful for understanding the biological features of metallic materials for medicinal applications.

Published: March 2023

Abstract
Fluorescence emission is a typical nonlinear phenomenon occurring during the femtosecond laser filamentation in air. The characteristics of nitrogen fluorescence emission induced by femtosecond vortex beams in air are experimentally studied. It is found that the topological charge has a great influence on the nitrogen fluorescence emission induced by a femtosecond filament: the fluorescence signals from nitrogen molecules (e.g., 337, 357 and 380 nm spectral lines) and molecular nitrogen ions (e.g., 391 and 428 nm spectral lines) differ much in the intensity distribution along the propagation direction. The discrepancy is explained by revisiting the generation mechanisms for nitrogen fluorescence, and it is found that the intersystem crossing scheme can account for it, indicating that the intersystem crossing scheme plays the main role in the formation of

Ghost and Laplacian instabilities in teleparallel Horndeski gravity
Authors: Capozziello Salvatore , Caruana Maria , Levi Said Jackson , Sultana Joseph 
Published: March 2023

Abstract
Teleparallel geometry offers a platform on which to build up theories of gravity where
torsion rather than curvature mediates gravitational interaction. The teleparallel analogue of
Horndeski gravity is an approach to teleparallel geometry where scalar-tensor theories are
considered in this torsional framework. Teleparallel gravity is based on the tetrad
formalism. This turns out to result in a more general formalism of Horndeski gravity. In other
words, the class of teleparallel Horndeski gravity models is much broader than the standard metric
one. In this work, we explore constraints on this wide range of models coming from ghost and
Laplacian instabilities. The aim is to limit pathological branches of the theory by fundamental
considerations. It is possible to conclude that a very large class of models results physically
viable.
Joint constraints on cosmological parameters using future multi-band gravitational wave standard siren observations*

Published: March 2023

Abstract
Gravitational waves (GWs) from compact binary coalescences can be used as standard sirens to explore the cosmic expansion history. In the next decades, it is anticipated that we could obtain the multi-band GW standard siren data (from nanohertz to a few hundred hertz), which are expected to play an important role in cosmological parameter estimation. In this work, we provide, for the first time to the best of our knowledge, joint constraints on cosmological parameters using the future multi-band GW standard siren observations. We simulate the multi-band GW standard sirens based on the SKA-era pulsar timing array (PTA), Taiji observatory, and Cosmic Explorer (CE) to perform cosmological analysis. In the ΛCDM model, we find that the joint PTA+Taiji+CE data could provide a tight constraint on the Hubble constant with a

precision. Moreover, PTA+Taiji+CE could break the cosmological parameter degeneracies generated by CMB, especially in the dynamical dark energy models. When combining the PTA+Taiji+CE data with the CMB data, the constraint precisions of
