Is ‘he’ still here?
Authors: Piepers Joske , Backus Ad , Swanenberg Jos 
Published: November 2023

Abstract
Various non-standard language varieties in the Netherlands traditionally allow for the use of masculine personal
subject pronouns (i.e. regionally distinct variants of hij ‘he’) in reference to women. While this practice is
well-documented within Dutch dialectology, especially during the twentieth century, it is unclear to what extent this feature
still exists nowadays. Moreover, the use of masculine subject forms for female reference has not previously been described for
Limburgian dialects. This paper offers a start to filling these gaps, by providing insight into the contemporary use of ‘he’ for
women in Dutch dialects, with a specific focus on occurrences in Dutch Limburg. We report on a Twitter query and three interviews,
showing (i) that the use of ‘he’ for women still exists in various Dutch dialects, and (ii) how
native speakers of a Limburgian dialect use and perceive this feature of their dialect.
Argument doubling with proper nouns in spoken Dutch
Authors: Wets Imke , Suijkerbuijk Michelle , den Hartog Maria , de Hoop Helen 
Published: November 2023

Abstract
Argument doubling, also known as (contrastive) left-dislocation, is common in spoken Dutch, but it is unclear exactly what triggers it. Earlier proposals in the literature showed that the construction is not used for marking contrast, and suggested it is used for marking shifted topics instead. However, the results from a Spoken Dutch Corpus study on argument doubling with proper nouns demonstrate that topic-shift does not adequately characterize the construction’s function either. Further examination of our corpus data shows that at least for proper nouns, Dutch argument doubling mostly occurs when a new referent is introduced into the discourse, but that this referent does not necessarily become the topic of the discourse. We hypothesize that argument doubling is a way of giving speakers and/or hearers some extra time to establish and/or process the new discourse referent in the discourse, regardless of whether it will become a discourse-topic after its introduction.
Technological advances for getting insight into the learning capacities of birds in the vocal domain
Authors: Derégnaucourt Sébastien , Araguas Alice , Guellaï Bahia 
Published: November 2023

Abstract
Birds produce different types of sounds in different contexts such as begging for food in youngsters, alerting to
a danger, defending a territory or attracting a sexual partner. About half of the bird species are able to transform their
vocalizations through imitation, improvisation or invention of sounds. Here we review the different experimental procedures that
have been used to study the learning capacities of birds in the vocal domain and in the auditory domain, with a particular
emphasis on recent technological developments. Nowadays, it is possible to record individual vocalizations of birds living in
social groups or to record continuously the vocal ontogeny of birdsong. In conditioning experiments, new paradigms have
successfully replaced food rewards with a socio-sexual reward. It is possible to engage in vocal interactions with a bird using
dedicated computer systems. In both the laboratory and more recently in the field, different techniques have been used to train
young oscine songbirds to learn from acoustic models. The use of virtual social environments and robots as social agents are also
promising avenues. All together, these new techniques will permit researchers to explore more deeply the umwelt of bird
species.
Sonic enrichment at the zoo
Authors: Kleinberger Rébecca 
Published: November 2023

Abstract
There is a strong disconnect between humans and other species in our societies. Zoos particularly expose this
disconnect by displaying the asymmetry between visitors in search of entertainment, and animals often suffering from a lack of
meaningful interactions and natural behaviors. In zoos, many species are unable to mate, raise young, or exhibit engagement
behaviors. Enrichment is a way to enhance their quality of life, enabling them to express natural behaviors and reducing
stereotypies. Prior work on sound-based enrichment and interactivity suggest that a better understanding of animals’ sensory needs
and giving them options to shape their surroundings can yield substantial benefits. However, current zoo management and
conservation practices lack tools and frameworks to leverage innovative technology to improve animal well-being and zookeepers’
ability to care for them. Ethical considerations are called for in developing such interventions as human understanding of
animals’ worlds is still limited, and assumptions can have detrimental consequences. Based on several interventions, four
principles are proposed to guide a more systematic implementation of sonic enrichment in zoos. The goal is to lay the groundwork
for the design of the zoos of the future, with a focus on sounds, for the benefit of the animals.
Poincaré invariance of spinning binary dynamics in the post-Minkowskian Hamiltonian approach
Authors: Lee Hojin , Lee Sangmin 
Published: November 2023

Abstract
We initiate the construction of the global Poincaré algebra generators in the context of the post-Minkowskian Hamiltonian formulation of gravitating binary dynamics in isotropic coordinates that is partly inspired by scattering amplitudes. At the first post-Minkowskian order, we write down the Hamiltonian in a form valid in an arbitrary inertial frame. Then we construct the boost generator at the same order which uniquely solves all the equations required by the Poincaré algebra. Our results are linear in Newton’s constant but exact in velocities and spins, including all spin-multipole moments. We also construct explicitly the canonical transformations that prove the equivalence between our new generators and the corresponding generators in the ADM coordinates up to the second post-Newtonian order.

Published: November 2023

Abstract
The measurement model of ultrasonic bone cutting force is an urgent problem to be solved in the application of ultrasonic osteotomy in robot assisted orthopedic surgery, which is of great significance for achieving bone layer perception and cutting force control during the surgical process. This article proposes an indirect measurement method of ultrasonic bone cutting force based on strain. Firstly, according to the axial vibration strain distribution curve of the ultrasonic osteotomy, the optimal measurement position for the strain gauge is selected as the high strain position (with a high signal-to-noise ratio), and the temperature compensation strategy of the dual strain gauge method is used to reduce or eliminate the thermal effects during the strain measurement. Then, the Pearson correlation coefficient between strain and cutting force in different cutting directions is calculated, and there is a strong positive correlation between strain and cutting force. Finally, the least squares method was used to obtain indirect measurement models of ultrasonic bone cutting force based on strain in different cutting directions. The experimental results showed that the waveform of cutting force measured indirectly based on strain was in good agreement with the waveform of cutting force measured directly by the force sensor. The error between the effective value of indirect measurement of cutting force and the effective value of direct measurement of cutting force did not exceed 13%, which verified the feasibility and effectiveness of this method. The indirect measurement models of ultrasonic bone cutting force based on strain will become a cost-effective choice with good accuracy and high sensitivity, providing a theoretical basis for orthopedic robots to perceive and control cutting force, and promoting the clinical application of ultrasonic osteotomy in orthopedic robots.
Machine learning accelerated search for the impact limit of the graphene/aluminum alloy whipple structure
Authors: Ge Qinghong , Zhu Weiping , Jiang Jin-Wu 
Published: November 2023

Abstract
This paper proposes a Whipple structure to enhance the impact resistance of graphene/aluminum alloy composites by varying the interlayer spacing between graphene and aluminum alloy. The increased interlayer spacing provides more deformation space for the graphene to absorb more deformation energy, and enables the formation of a debris cloud from the bullet fragments and graphene fragments, significantly reducing the impact energy per unit area of the next material. The impact limit serves as a critical metric for assessing the impact resistance of the Whipple structure. Based on molecular dynamics simulations, we developed a machine learning model to predict the protection of aluminum alloy, and quickly determined the impact limits of velocity, bullet radius, and interlayer spacing by using the machine learning model. An empirical equation for the impact limit of interlayer spacing was established. The results showed that non-zero interlayer spacing can significantly improve the impact resistance of the hybrid structure; to fully exploit the superior impact resistance of this Whipple structure, the number of graphene layers should be at least 3. Furthermore, at high impact velocities and large bullet radii, the impact limit of the interlayer spacing exhibits a substantial correlation with the number of graphene layers. These results provide valuable information for the design of the impact resistance of the graphene/aluminum alloy composites.

Abstract

Objective. The percentages of cardiac and sympathetic baroreflex patterns detected via baroreflex sequence (SEQ) technique from spontaneous variability of heart period (HP) and systolic arterial pressure (SAP) and of muscle nerve sympathetic activity (MSNA) burst rate and diastolic arterial pressure (DAP) are utilized to assess the level of the baroreflex engagement. The cardiac baroreflex patterns can be distinguished in those featuring both HP and SAP increases (cSEQ++) and decreases (cSEQ−−), while the sympathetic baroreflex patterns in those featuring a MSNA burst rate decrease and a DAP increase (sSEQ+−) and vice versa (sSEQ−+). The present study aims to assess the modifications of the involvement of the cardiac and sympathetic arms of the baroreflex with age and postural stimulus intensity. Approach. We monitored the percentages of cSEQ++ (%cSEQ++) and cSEQ−− (%cSEQ−−) in 100 healthy subjects (age: 21–70 years, 54 males, 46 females), divided into five sex-balanced groups consisting of 20 subjects in each decade at rest in supine position and during active standing (STAND). We evaluated %cSEQ++, %cSEQ−−, and the percentages of sSEQ+− (%sSEQ+−) and sSEQ−+ (%sSEQ−+) in 12 young healthy subjects (age 23 ± 2 years, 3 females, 9 males) undergoing incremental head-up tilt. Main results. We found that: (i) %cSEQ++ and %cSEQ−− decreased with age and increased with STAND and postural stimulus intensity; (ii) %sSEQ+− and %sSEQ−+ augmented with postural challenge magnitude; (iii) the level of cardiac and sympathetic baroreflex engagement did not depend on either the absolute value of arterial pressure or the direction of its changes. Significance. This study stresses the limited ability of the cardiac and sympathetic arms of the baroreflex in controlling absolute arterial pressure values and the equivalent ability of both positive and negative arterial pressure changes in soliciting them.
Frequency response of terahertz electro-optic sampling detection technology with thin GaSe crystal
Authors: Li Qiang-Shuang , Wang Jing-Yi , Sun Chang-Ming , Du Hai-Wei 
Published: November 2023

Abstract
GaSe crystal has good applications in the broadband terahertz pulse generation and electro-optic sampling detection technology. In this paper, the frequency responses of GaSe crystal with different thicknesses in the electro-optic sampling (EOS) detection technology are investigated based on the numerical calculations. Then, the pulse distortions of terahertz induced by the EOS detection technology with thin GaSe crystal are investigated. It is found that the lower the central frequency of the terahertz pulse is, the less the distortion is. When the central frequency of terahertz pulse is higher than 4 THz, the pulse distortions, including the frequency shift and the bandwidth changing, are greatly obvious. Both induced by the EOS technology with different thickness of GaSe crystal are also given in detail. This work provides a good reference to evaluate the performance of EOS detection technology with thin GaSe crystal in the broadband terahertz science and technology.
Physical factors influencing dielectric polymer electrical breakdown by generated space charges under a strong electric field
Authors: Boughariou F , Belgaroui E 
Published: November 2023

Abstract
The present work constitutes a contribution in studying the breakdown phenomenon generated by the electron–hole dynamics during their bipolar transport in a polyethylene film subjected to strong dc electrical field. This contribution is addressed to the analysis of the determining physical parameters effects in the electrical breakdown process within a low density polyethylene LDPE film. Indeed, the previous modeling and analysis works for breakdown phenomenon are still limited in this topic. In this regard, using our model of bipolar transport in the charged dielectrics, we present, in this article, a more complete analysis affecting more physical parameters influencing the breakdown transient dynamic process. Theses parameters are namely the applied field, the carrier mobility, the sample temperature, the injection barrier and the coefficients associated with the bipolar transport physical mechanisms. Briefly, our results highlight the existence of two classes of inverse effects and allowed us to establish new power laws. Our validation with previous work is addressed to the effect of the sample thickness on the breakdown field.
Electronic thermal conductivity of few-layer black phosphorus
Authors: Gaonkar Narayan , Vaidya R G 
Published: November 2023

Abstract
The theoretical investigations of anisotropic electronic thermal conductivity of nanoscale black phosphorus along zigzag and armchair directions are presented. Electrons in black phosphorus assumed to be scattered by in-plane linear dispersion phonons and out-of-plane quadratic dispersion phonons via deformation potential couplings. The individual contributions from in-plane phonon and out-of-plane phonon processes to the electronic thermal conductivity show dominant role of in-plane phonon processes. The anisotropic behaviour of electronic thermal conductivity is noticed and found to be sensitive to the carrier density and temperature. Role and relative importance of anisotropic electronic thermal conductivity in the analysis of experimental thermal conductivity data of nanoscale black phosphorus samples is investigated.
Tunneling conductance regulated by the electrostatic barrier in monolayer black phosphorene
Authors: Li Yun , Wang Dali , Jin Guojun 
Published: November 2023

Abstract
We investigate the tunneling conductance of monolayer black phosphorene through double magnetic barriers modulated by the electrostatic barrier. This magnetic barrier is generated by two ferromagnetic strips deposited on monolayer phosphorene and can form parallel (P) and antiparallel (AP) structures. Applying a voltage to a ferromagnetic strip will create an electrostatic barrier. The transmission of P and AP magnetic structures is calculated using the transfer matrix. Tunneling conductance is given by Landauer–Büttiker theory. Our results show that under double electrostatic barriers modulation, the AP conductance of the system is zero except for sharp peaks, while the P conductance has a certain value, which implies a large tunneling magnetoresistance. However, in the case of single electrostatic barrier modulation, the conductance becomes flat. For the Fermi level in the valence band, the movement of the Fermi level leads to the severe mismatching of transmitted wave vectors in the barrier region, resulting a positive and negative oscillation magnetoresistance. This may be useful for designing memory using a two-dimensional electron gas system.
Topological Phase Transitions of the Non-Hermitian Electromagnetic Media with Magneto-electric Effect
Authors: Zhang Lu 
Published: November 2023

Abstract
The non-Hermitian topological properties of electromagnetic media have attracted much attention. In the present work, we reveal the properties of the topology of non-Hermitian electromagnetic media with a magneto-electric effect. By renormalizing the permittivity, we acquire the electromagnetic media topological phase diagram under the influence of magneto-electric effects. We find that the topological phase transition in the system is driven by the renormalization of the permittivity and permeability. This work provides an alternative way to explore the various topological phases of the electromagnetic media.
Study on the detection technology and response of isolated anomalous bodies in transient electromagnetic wave logging of formations
Authors: Liu Yuxuan , Hu Xufei , Dai Shun 
Published: November 2023

Abstract
Transient electromagnetic wave logging is one of the key methods for detecting underground formations, especially for identifying anomalies near wells using higher frequencies and resolutions. In this paper, the 3D TDFD (three-dimensional time-domain finite-difference) simulation method is used to investigate the detection technique of wellbore anomalies based on the scattered field of transient electromagnetic waves and its significance in underground structure identification and localization. The research results show that isolated anomalies can be effectively characterized by extracting the scattering field response generated by block-shaped anomalies while eliminating the contribution of background media. Analyzing the measurement response caused by scatterers provides important information about the position, size, and response magnitude of the anomalies, offering an effective method for detecting and identifying wellbore anomalies. Applying this detection technique enriches the existing methods for wellbore anomaly detection, providing important theoretical and technical foundations for petroleum and solid mineral exploration, as well as the construction of underground defense engineering.

Abstract
With the development of drone technology, drones are gradually being applied in various industries. But with the increasingly complex electromagnetic environment, the impact of electromagnetic interference on drones is also gradually increasing. The GPS is one of the important components of unmanned aerial vehicles. This paper establishes a 1.58 GHz frequency band circularly polarized microstrip patch antenna model. It uses this model to simulate the coupling effect of UWB pulses on the front door of the GPS. UWB pulses with different polarization directions and incidence angles were selected for coupling simulation research. The results indicate that the coupling effect is closely related to the polarization direction and incident direction angle of the pulse, and the coupling signal spectra under different conditions are obtained. This result guides subsequent experiments on the coupling effect of UWB pulses on unmanned aerial vehicles and research on the coupling mechanism.

Published: November 2023

Abstract
In the high-altitude electromagnetic pulse (HEMP) environment, high-intensity broadband electromagnetic pulse energy is transmitted to the display interface circuit through the interconnection cable, causing interference or damage to the internal electronic components and chips, resulting in various damage effects such as the display cannot be displayed normally, and even restart. To investigate the coupling effect of strong electromagnetic pulses on the display interface circuit, the existing field-line coupling model is utilized as the basis of this study, with a specific focus on the VGA interface. The influence of different terminal impedances on the coupling effect is examined, aiming to determine the significance of terminal impedances in the simulation estimation of interface circuit coupling response. A HEMP coupling signal loop model is established based on the signal loop defined in the VGA datasheet, replicating the normal working conditions of VGA. HEMP pulse injection experiments are conducted to compare the response waveforms of the simulated VGA interface equivalent impedance circuit model with the measured data. This allows the accuracy of the established equivalent impedance model to be verified using key parameters.

Abstract
The coaxial processing cavity is an important component of high-frequency electromagnetic water treatment devices. Due to its easy installation, wide applicability, and excellent scale removal effect, it has been widely used in various factories. To study the influence of excitation source waveform, processing cavity length, and anode-cathode radius ratio on the intensity and distribution of the electromagnetic field in the coaxial processing cavity under time-varying fields, this paper derives the numerical calculation formula for electromagnetic energy in the coaxial processing cavity based on the theory of electrostatic fields. The finite element method is used to visualize the intensity and distribution of the electromagnetic field in the coaxial processing cavity. By optimizing the structure of the coaxial processing cavity, the optimal range of the anode-cathode radius ratio is determined. The research results show that, under the conditions of electrostatic field theory, square waves have the maximum electromagnetic energy, the length of the processing cavity does not affect the distribution of the electromagnetic field, and the optimal anode-cathode radius ratio range is 0.375-0.5.
