Published: July 2022

AbstractThe construction industry occupies a high proportion of the global economy. However, with the energy consumption of construction enterprises, it still brings a series of serious environmental problems. Construction enterprises should take active green development behavior to respond. Based on enterprises’ green development behavior, this paper explores the influencing factors of green development behavior adopted by construction enterprises in China. Through literature analysis, this paper identifies that construction enterprises’ adoption of green development behaviors is influenced by technological, organizational and environmental factors. Then this paper constructs an index system of the influencing factors of green development behaviors adopted by enterprises. According to the data of construction enterprises from 2000 to 2020 of National Bureau of Statistics, an artificial neural network is used to construct the prediction model of influencing factors of green development behavior adopted by construction enterprises. The conclusions are as follows. (1) Construction enterprises’ adoption of green development behavior shows an upward trend over time. (2) Market share of construction enterprises is the most important factor to promote construction enterprises’ adoption of green development behavior. (3) The prediction model of influencing factors constructed in this paper is verified to be effective by the technology-organization-environment framework. This paper provides a reference for construction enterprises and the government to promote enterprises to adopt green development behavior, which is beneficial for construction enterprises to achieve green development faster.
Research on coupled cavity mechanical tuning extended interaction oscillator with broad tuning range
Authors: Qing Jie , Niu Xinjian , Liu Yinghui , Guo Guo , Li Hongfu 
Published: July 2022

This paper proposes a new way to improve the tuning range of the extended interaction oscillator (EIO). Compared with the conventional EIO structure, the fundamental wave changes from the forward wave to the backward wave when the circuit structure changes from the strong-coupling characteristic of the grating to the weak-coupling characteristic. Simultaneously, the tuning range of the EIO can be greatly enhanced by mechanically tuning the coupling cavity. The results show that, compared with the strong-coupling structure of the grating, the extended interaction oscillation circuit has stronger dispersion sensitivity and greater frequency tuning characteristics under the weak-coupling characteristics of the grating. By mechanically tuning the width of the coupling cavity by 0.8 mm, its center frequency can be varied by 9.5 GHz. This paper also studies and compares the electronic displacement jump phenomenon that occurs in the mechanical tuning process. Similar to the electronic voltage tuning, the output dips suddenly at the operating point of the coupling mismatch. The effective output can be obtained by changing the operating mode in conjunction with electronic tuning. This article provides a new reference method for expanding the tuning range of the extended interaction oscillator.
The emergence of conjunctions and phrasal coordination in Khanty
Authors: Borise Lena , Kiss Katalin É. 
Published: July 2022

Abstract
Prior to widespread contact with Russian, Khanty (Uralic; Finno-Ugric) did not have overt conjunctions or phrasal
coordination. Instead, Khanty texts from the late 19th–early 20th centuries only include examples of conjunction-less clausal juxtaposition,
which was used for both clausal and phrasal coordination. By comparing Khanty texts over the 20th century, we trace the emergence of overt
conjunctions and coordination of phrasal constituents. We show that overt conjunctions first appeared in the context of clausal
coordination, followed by coordination of smaller phrases. Based on novel elicitation data, we demonstrate that, in contemporary Khanty, (i)
overt conjunctions are commonplace, (ii) coordinated clausal constituents may be derived via phrasal coordination or clausal coordination
with conjunction reduction/ellipsis, but (iii) ellipsis of syntactic heads is banned (nouns & postpositions) or dispreferred (verbs).
Based on this diachronic picture, we conclude that the coordination of phrasal constituents only emerged in Khanty once overt conjunctions
became available. We derive this correlation from the Maximize On-line Processing principle (Hawkins
2004), and show that this maxim, usually invoked in the context of speech planning and production, can be successfully applied to
modelling language change.
Prognostics and health management for piezoresistive pressure sensor based on improved gated recurrent unit networks
Authors: Ruan Yi , Yuan Lifen , He Yigang , Li Zhigang , Yuan Weibo , Lu Li 
Published: July 2022

Abstract
Application fields for piezoresistive pressure sensors have become increasingly extensive in recent years. So a high reliability of the sensor is also required. However, considering that some sensors operate in hostile environments,the need to ensure continuous operation accuracy, prognostics, and health management (PHM) for piezoresistive pressure sensors should not be ignored. To solve this problem, a fault diagnosis and prognostic method that combines a support vector machine (SVM) and deep gated recurrent unit (DGRU) network optimized by hunter–prey optimization (HPO) is proposed in this paper. First, three sensor fault types are defined. Second, SVM is adopted to realize the fault diagnosis. Third, two layers of DGRU are employed to predict the health index, which is defined to represent the health state of the sensor. Meanwhile, the optimal parameters of the DGRU are optimized by HPO algorithms. Finally, the remaining useful life can be estimated by the predicted health index and failure threshold. The method proposed in this paper is proved to be effective and accurate. The fault diagnosis accuracy is 100% in the three fault types defined by this paper. The minimum mean absolute error is 6 × 10−5. It proves the proposed method of PHM in this paper is viable in a real application.
Molecular dynamics study of phonon thermal transport in borophene with random vacancy defects
Authors: Xu Dajie , Zhou Man , Wu Bingyang , Liu Jiaju , Zhang Ping 
Published: July 2022

Abstract
This study uses non-equilibrium molecular dynamics simulation to investigate the effect of random vacancy defects on the in-plane thermal conductivity of borophene phonon dispersion curves and phonon group velocities are used to explain the anisotropy of the thermal conductivity of borophene nanosheets and the transmission characteristics of the acoustic and optical branches. Further calculations for the in-plane thermal conductivity of borophene with random vacancy defects are carried out, and the calculations show that the thermal conductivity gradually decreases to a steady state with increasing defect concentration. The phonon density of states and phonon participation rate are used to explain describe the activity of phonons in borophene for further explaining the change of thermal conductivity. Finally, the effect of defects on thermal conductivity is further verified by the spatial distribution of localized intensity of borophene nanosheets.
Dynamics of a predator–prey system with nonlinear prey-taxis
Authors: Liu Changfeng , Guo Shangjiang 
Published: July 2022

Abstract
In this paper, we investigate a predator–prey system with nonlinear prey-taxis under Neumann boundary condition. For a class of chemotactic sensitive functions, we obtain the existence and boundedness of global classical solutions for initial boundary value problems in arbitrary dimensional space. In addition, we also study the local stability of the constant steady state solution, and obtain the global asymptotic stability of the steady state solution under different predation intensity by constructing appropriate Lyapunov functions. Furthermore, the steady state bifurcation, Hopf bifurcation and fold-Hopf Singularity are analysed in detail by using Lyapunov–Schmidt reduction method.
Characteristic approach to the soliton resolution
Authors: Bizoń Piotr , Cownden Bradley , Maliborski Maciej 
Published: July 2022

Abstract
As a toy model for understanding the soliton resolution phenomenon we consider a characteristic initial boundary value problem for the 4d equivariant Yang–Mills equation outside a ball. Our main objective is to illustrate the advantages of employing outgoing null (or asymptotically null) foliations in analyzing the relaxation processes due to the dispersal of energy by radiation. In particular, within this approach it is evident that the endstate of evolution must be non-radiative (meaning vanishing flux of energy at future null infinity). In our toy model such non-radiative configurations are given by a static solution (called the half-kink) plus an alternating chain of N decoupled kinks and antikinks. We show numerically that the configurations N = 0 (static half-kink) and N = 1 (superposition of the static half-kink and the antikink which recedes to infinity) appear as generic attractors and we determine a codimension-one borderline between their basins of attraction. The rates of convergence to these attractors are analyzed in detail.

Justification of a nonlinear sixth-order thin-film equation as the reduced model for a fluid–structure interaction problem
Authors: Bukal Mario , Muha Boris 
Published: July 2022

Abstract
Starting from a nonlinear 2D/1D fluid–structure interaction problem between a thin layer of a viscous fluid and a thin elastic structure, in the vanishing limit of the relative fluid thickness, we rigorously derive a sixth-order thin-film equation describing the dynamics of vertical displacements of the structure. The procedure is essentially based on quantitative energy estimates in terms of the relative fluid thickness and a uniform no-contact result between the structure and the solid substrate. The sixth-order thin-film equation is justified in the sense of strong convergence of rescaled structure displacements to the unique positive classical solution of the thin-film equation. Moreover, the limiting fluid velocity and pressure can be expressed solely in terms of the solution to the thin-film equation.
Stirring speeds up chemical reaction
Authors: He Siming , Kiselev Alexander 
Published: July 2022

Abstract
We consider absorbing chemical reactions in a fluid flow modelled by the coupled advection–reaction–diffusion equations. In these systems, the interplay between chemical diffusion and fluid transportation causes the enhanced dissipation phenomenon. We show that the enhanced dissipation time scale, together with the reaction coupling strength, determines the characteristic time scale of the reaction.
Production and performance of a low temperature shape-memory actuator based on twisted-coiled spring mechanics
Authors: Jafari Horastani Sahar , Ghane Mohammad , Karevan Mehdi 
Published: July 2022

Abstract
Demand for new types of actuators continues to grow, and novel approaches have been made possible by the advent of new materials and fabrication strategies. Self-powered actuators have attracted significant attention owing to their ability to be driven by elements in ambient environments. This type of actuator can be used in flexible strain sensors, artificial muscles, soft robotics, and smart breathing textiles. However, petrochemical-based polymers are generally environmentally unfriendly and cause ecological problems. The use of biodegradable polymers is one of the preferred solutions to ecological problems. Polylactic acid is a biodegradable and biocompatible polymer with a high potential. In this study, nanoclay reinforced polylactic acid/thermoplastic polyurethane was used as a precursor. The yarn that was produced was highly twisted. The twisted yarn was then shaped into a coiled structure via mandrel annealing. An apparatus was designed to investigate the thermal actuation behavior of twisted-coiled yarn in an isometric state. The blocked force and free stroke were calculated in an isometric state by using linear material equations. The thermal actuation behavior of the twisted-coiled yarn was also studied in the isotonic state. This precursor exhibited a considerable two-way shape-memory effect in a twisted-coiled structure. It also showed a significant reversible contraction stroke within the low temperature range. The theoretical stroke was determined using two different models: the force–stroke equation and spring mechanics. The theoretical results were compared with the experimental results, which revealed acceptable agreement between the theoretical and experimental values.
Magnon-driven dynamics of frustrated skyrmion in synthetic antiferromagnets: effect of skyrmion helicity oscillation

Published: July 2022

Abstract
A theoretical study on the interplay of frustrated skyrmion and magnons should reveal new physics and future experiment designs. In this study, we investigate the magnon-driven dynamics of frustrated skyrmion in synthetic antiferromagnets based on micromagnetic simulations, focusing on the effect of skyrmion helicity oscillation. The oscillation speed and Hall angle of the frustrated skyrmion depending on the magnon intensity and damping constant are simulated, which demonstrates that the skyrmion helicity oscillation effectively suppresses Hall motion. The elastic scattering theory reveals that the helicity oscillation affects the scattering cross-section of injected magnons, which in turn effectively modulates the skyrmion Hall motion. This study provides a comprehensive understanding of magnon-skyrmion scattering in frustrated magnets, thus benefiting future spintronic and magnonic applications.
Tunable Brillouin-Raman multi-wavelength fiber laser with a linear cavity configuration
Authors: Zhou Zezhong , Yang Qian , Chen Yapeng , Chen Mengmeng , Zhang Zuxing 
Published: July 2022

Abstract
A tunable Brillouin-Raman multi-wavelength fiber laser has been proposed and demonstrated in a linear cavity configuration, where stimulated Raman scattering and stimulated Brillouin scattering occur simultaneously in the dispersion compensation fiber. The influence of Brillouin pump (BP) and Raman pump (RP) power on the obtained Brillouin Stokes lines has been investigated in detail. The experimental results show that when BP wavelength is 1545 nm, 63 orders of Stokes lines can be obtained at most, and the interval between adjacent lines is about 0.08 nm. Moreover, there are two opposite relations between the number of the generated Stokes lines and the BP power within the whole tunable range of 1520–1575 nm (55 nm), depending on the Raman gain. The proposed laser featuring simple structure will enable promising potentials in optical communications and optical sensor systems.
Comments on the mass sheet degeneracy in cosmography analyses
Authors: Teodori Luca , Blum Kfir , Castorina Emanuele , Simonović Marko , Soreq Yotam 
Published: July 2022

Abstract
We make a number of comments regarding modeling degeneracies in strong lensing measurements of the Hubble parameter H
0. The first point concerns the impact of weak lensing associated with different segments of the line of sight. We show that external convergence terms associated with the lens-source and observer-lens segments need to be included in cosmographic modeling, in addition to the usual observer-source term, to avoid systematic bias in the inferred value of H
0. Specifically, we show how an incomplete account of some line of sight terms biases stellar kinematics as well as ray tracing simulation methods to alleviate the mass sheet degeneracy.

The second point concerns the use of imaging data for multiple strongly-lensed sources in a given system.
We show that the mass sheet degeneracy is not fully resolved by the availability of multiple sources: some degeneracy remains because of differential external convergence between the different sources.

Similarly, differential external convergence also complicates the use of multiple sources in addressing the approximate mass sheet degeneracy associated with a local (“internal”) core component in lens galaxies. This internal-external degeneracy is amplified by the non-monotonicity of the angular diameter distance as a function of redshift.

For a rough assessment of the weak lensing effects, we provide estimates of external convergence using the nonlinear matter power spectrum, paying attention to non-equal time correlators.
QED effects on phase transition and Ruppeiner geometry of Euler-Heisenberg-AdS black holes*
Authors: Ye Xu , Chen Zi-Qing , Li Ming-Da , Wei Shao-Wen 
Published: July 2022

Abstract
Considering the quantum electrodynamics (QED) effect, we study the phase transition and Ruppeiner geometry of Euler-Heisenberg anti-de Sitter black holes in the extended phase space. For negative and small positive QED parameters, we observe a small/large black hole phase transition and reentrant phase transition, respectively, whereas a large positive value of the QED parameter ruins the phase transition. Phase diagrams for each case are explicitly shown. Then, we construct the Ruppeiner geometry in thermodynamic parameter space. Different features of the corresponding scalar curvature are shown for both the small/large black hole phase transition and reentrant phase transition cases. Of particular interest is the additional region of positive scalar curvature, indicating a dominant repulsive interaction among black hole microstructures, for the black hole with a small positive QED parameter. Furthermore, universal critical phenomena are observed for the scalar curvature of Ruppeiner geometry. These results indicate that the QED parameter has a crucial influence on the black hole phase transition and microstructure.
Entropic destruction of heavy quarkonium in a rotating hot and dense medium from holography*
Authors: Wu Ping-ping , Zhang Zi-qiang , Zhu Xiangrong 
Published: July 2022

Abstract
Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force, which would induce the dissociation of heavy quarkonium. In this study, we investigated the entropic force in a rotating hot and dense medium using AdS/CFT correspondence. It was found that the inclusion of angular velocity increases the entropic force, thus enhancing quarkonium dissociation, while chemical potential has the same effect. The results imply that the quarkonium dissociates easier in rotating medium compared with the static case.
Intensity dependence of sub-harmonics in cortical response to photic stimulation
Authors: Phogat Richa , Parmananda P , Prasad Ashok 
Published: July 2022

Abstract

Objective. Periodic photic stimulation of human volunteers at 10 Hz is known to entrain their electroencephalography (EEG) signals. This entrainment manifests as an increment in power at 10, 20, 30 Hz. We observed that this entrainment is accompanied by the emergence of sub-harmonics, but only at specific frequencies and higher intensities of the stimulating signal. Thereafter, we describe our results and explain them using the physiologically inspired Jansen and Rit neural mass model (NMM). Approach. Four human volunteers were separately exposed to both high and low intensity 10 Hz and 6 Hz stimulation. A total of four experiments per subject were therefore performed. Simulations and bifurcation analysis of the NMM were carried out and compared with the experimental findings. Main results. High intensity 10 Hz stimulation led to an increment in power at 5 Hz across all the four subjects. No increment of power was observed with low intensity stimulation. However, when the same protocol was repeated with a 6 Hz photic stimulation, neither high nor low intensity stimulation were found to cause a discernible change in power at 3 Hz. We found that the NMM was able to recapitulate these results. A further numerical analysis indicated that this arises from the underlying bifurcation structure of the NMM. Significance. The excellent match between theory and experiment suggest that the bifurcation properties of the NMM are mirroring similar features possessed by the actual neural masses producing the EEG dynamics. NMMs could thus be valuable for understanding properties and pathologies of EEG dynamics, and may contribute to the engineering of brain–computer interface technologies.
Thermodynamic symmetry resolved entanglement entropies in integrable systems
Authors: Piroli Lorenzo , Vernier Eric , Collura Mario , Calabrese Pasquale 
Published: July 2022

Abstract
We develop a general approach to compute the symmetry-resolved Rényi and von Neumann entanglement entropies (SREE) of thermodynamic macrostates in interacting integrable systems. Our method is based on a combination of the thermodynamic Bethe ansatz and the Gärtner–Ellis theorem from large deviation theory. We derive an explicit simple formula for the von Neumann SREE, which we show to coincide with the thermodynamic Yang–Yang entropy of an effective macrostate determined by the charge sector. Focusing on the XXZ Heisenberg spin chain, we test our result against iTEBD calculations for thermal states, finding good agreement. As an application, we provide analytic predictions for the asymptotic value of the SREE following a quantum quench.
The review of methods for a real-time monitoring and forecasting bird strike risk level
Authors: Szafrański B , Zieja M , Wójcik J 
Published: July 2022

Abstract
A high level of flight safety is a priority for all aviation organizations in the world. The negative impact of the natural environment on air operations is one of the most common factors causing the situations exerting a negative influence on flight safety (in short-aviation occurrence) in the Polish Army. The most common reason of the aviation occurrence connected with the environment area is the bird strike. The lack of a method for real-time monitoring and forecasting bird strike risk level is a significant gap in the proactive approach to flight safety within the Polish Air Force. The article presents a review of the methods for monitoring and forecasting the intensity of bird movements, which were used to build advisory systems used by air forces of the United States, Germany, the Netherlands, Belgium and Israel. The article consists of summary of most important properties of the methods and analysis in terms of their applicability in the Polish conditions. Particular attention was paid to the complicated network of routes of bird species occurring on Polish territory. Finally, after proving the incomplete usefulness of the above-mentioned methods in Polish conditions, the need to develop a more adequate method was justified.
