Negotiating leader identities through indirect mockery in talk about decision-making in a distributed
leadership context
Authors: Salomaa Elina , Van De Mieroop Dorien , Lehtinen Esa 
Published: December 2023

Abstract
In this article, we scrutinise how humour, and in particular, indirect mockery contributes to the construction of
leader identities in talk about decision-making in an organisation characterized by a distributed leadership
context. So rather than focusing on decision-making episodes themselves, we tease out an aspect of the goal achievement side of
the leadership influence process. Through multimodal discourse analysis, we focus on episodes in which the implementation side of
decisions is discussed and in which the head of the team initiates a humorous sequence, as this turned out to be an integral part
of talk about decision-making. We found that the humour was always oriented towards upper management and that it could serve
various functions. Overall, we argue that indirect mockery was a crucial means to navigate the tension that emerges from the team
head’s position within the complex leadership constellation, thus offering a critical perspective on distributed leadership.
Undertaking One Health Research with Australian Aboriginal and Torres Strait Islander Communities: Implications of a One Health Pilot Study
Authors: Riley Tamara , Meredith Anna , Anderson Neil E. , Cumming Bonny , Thandrayen Joanne , Lovett Raymond 
Published: December 2023

Abstract
This case study presents the research process and learnings from undertaking One Health research within Australian Aboriginal and Torres Strait Islander community settings. One Health is relevant to Australian Aboriginal and Torres Strait Islander communities where people and animals (commonly dogs and cats) live closely together and face health risks due to barriers in accessing animal health care. One Health is an appropriate approach to understanding and addressing health disparities as it aligns with community and cultural contexts that recognise the relationships between the health of people, animals and the shared environment. However, with minimal evidence in this space, the contribution of One Health to Aboriginal and Torres Strait Islander health is not well understood limiting the ability to implement One Health approaches and address the needs of communities, families, animals and the environment. This case study describes the research approach, methodology and implications from a pilot One Health study undertaken with Aboriginal and Torres Strait Islander communities that adopted Indigenous research methodologies within a One Health framework.

Tidal effects in 4D-charged Einstein-Gauss-Bonnet gravity black hole
Authors: Asgher M , Abbas G 
Published: December 2023

Abstract
In this paper, we study the geodesic deviation between two nearby geodesics. For this process, we calculated the geodesic equation and radial motion of test particles. Also, the radial and angular tidal forces have been investigated using the curvature tensor in tetrad form. The radial tidal forces in 4D charged Einstein-Gauss-Bonnet gravity black hole show a tidal effect with a small value of radial coordinate r. The angular tidal forces show converse behavior as compared to the radial tidal forces at the short value of radial coordinate r. The radial and angular tidal forces have the same behavior at the immense value of radial coordinate r. The geodesic deviation paths depend on the charge Q parameter and Gauss-Bonnet parameter α of the black hole. We have compared our result with the 4D uncharged Einstein-Gauss-Bonnet gravity black hole and Reissner-Nordström with consideration of two kinds of initial conditions.

Abstract
This paper investigates the comparative feature of Graphene Source Single Material Gate Vertical Tunnel FET (SMG-GR-VTFET) and Graphene Source Double Material Gate VTFET (DMG-GR-VTFET) on DC, analog/RF and linearity applications using Sentaurus TCAD simulator. The results show that both devices outperforms in DC characteristics, including ambipolar current, subthreshold swing (SS), ION/IOFF ratio etc The study focuses on important figures of merit (FOMs) such as transconductance (gm), output conductance (gd), cut-off frequency (ft), second-order transconductance (gm2), third-order transconductance (gm3), VIP2, and VIP3, which are all improved due to high mobility of graphene leads to improved band-to-band tunneling. The observed ION is 5.2 × 10−4 (1.1 × 10−3 A/μm), IOFF is 1.439 × 10−13 (2.28 × 10−16A/μm) and ION/IOFF ratio of 3.613 × 109 (4.824 × 1012) for SMG-GR-VTFET (DMG-GR-VTFET), respectively. It is seen that maximum gm is 2.96 × 10−3 (2.59 × 10−3 S μm−1) and cut-off frequency (ft) values of 1.1 × 1011 (1.85 × 1011 Hz) for SMG-GR-VTFET (DMG-GR-VTFET), respectively. Regarding the Linearity parameter VIP2 value is 2.71 V (0.99 V), respectively, for SMG-GR-VTFET (DMG-GR-VTFET). These results suggest that Graphene Source Vertical Tunnel FET is an excellent choice for analog and high-frequency applications.

/ZnO:Al/IZO as top subcell and IZO/GaSe/CI(G)S/CIGS-P+ as bottom subcell. The standalone optimised subcells exhibited power conversion efficiencies of 27.03% (CH3NH3SnI3 based cell) and 24.42% (CIGS based cell), with the tandem configuration showing a combined power conversion efficiency of 51.45%. Band gap optimisation of the CIGS based solar cell also revealed that its gallium content had to be nullified, which is a favourable outcome considering the high cost of gallium. Furthermore, the tandem device also exhibited excellent quantum efficiency while spanning the UV-Vis-NIR range of photon wavelength absorption, as a result of the CI(G)S based subcell complementing the top CH3NH3SnI3 based subcell.
Wavelet representation of hardcore bosons
Authors: Granet Etienne 
Published: December 2023

Abstract
We consider the one-dimensional Tonks–Girardeau gas with a space-dependent potential out of equilibrium. We derive the exact dynamics of the system when divided into n boxes and decomposed into energy eigenstates within each box. It is a representation of the wave function that is a mixture between real space and momentum space, with basis elements consisting of plane waves localized in a box, giving rise to the term ‘wavelet’. Using this representation, we derive the emergence of generalized hydrodynamics in appropriate limits without assuming local relaxation. We emphasize that a generalized hydrodynamic behaviour emerges in a high-momentum and short-time limit, in addition to the more common large-space and late-time limit, which is akin to a semi-classical expansion. In this limit, conserved charges do not require numerous particles to be described by generalized hydrodynamics. We also show that this wavelet representation provides an efficient numerical algorithm for a complete description of the out-of-equilibrium dynamics of hardcore bosons.
Improved mean-field dynamical equations are able to detect the two-step relaxation in glassy dynamics at low temperatures
Authors: Machado David , Mulet Roberto , Ricci-Tersenghi Federico 
Published: December 2023

Abstract
We study the stochastic relaxation dynamics of the Ising p-spin model on a random graph, which is a well-known model with glassy dynamics at low temperatures. We introduce and discuss a new closure scheme for the master equation governing the continuous-time relaxation of the system, which translates into a set of differential equations for the evolution of local probabilities. The solution to these dynamical mean-field equations describes the out-of-equilibrium dynamics at high temperatures very well, notwithstanding the key observation that the off-equilibrium probability measure contains higher-order interaction terms not present in the equilibrium measure. In the low-temperature regime, the solution to the dynamical mean-field equations shows the correct two-step relaxation (a typical feature of glassy dynamics), but with a too-short relaxation timescale. We propose a solution to this problem by identifying the range of energies where entropic barriers play a key role and defining a renormalized microscopic timescale for the dynamical mean-field solution. The final result perfectly matches the complex out-of-equilibrium dynamics computed through extensive Monte Carlo simulations.

Published: December 2023

Abstract
The coordinate frame is not only the foundation for depicting the shape and changes of the Earth and expressing geospatial information but also the crucial geospatial information infrastructure for expanding human activities and promoting social development. Research on satellite navigation and positioning reference stations considering linear motion will be of great significance for navigation and positioning. Therefore, this paper first deduces the transformation formula between different international terrestrial reference frames (ITRF) and the transformation relationship between different reference epochs. Second, a comparison experiment is conducted to analyze the influence of coordinates under different reference frames and epochs on the accuracy of the international GNSS service (IGS) baseline solution results. Finally, stability analysis is performed considering the effect of linear motion on the urban frame points. The results show that using the coordinates under the reference frame and epochs that best fit the measurement time for the baseline solution gives the most reliable results.
Modal Identification of Aircraft Time-varying Structure Based on Fiber Grating Measurement
Authors: Wang Yi , Yue Zhenjiang , Liu Li 
Published: December 2023

Abstract
To meet the increasing mission requirements, the time-varying characteristics of the aircraft structural system have been increasingly considered and utilized. Therefore, it is significant to obtain the structural modal parameters during the mission of the aircraft. However, the traditional electrical sensors have many limitations in the online measurement of spacecraft structure, and fiber grating sensors are expected to better adapt to the requirements. The online modal parameter identification methods of time-varying structures also lack sufficient research. The traditional modal parameter identification methods include non-parametric method and parametric method. However, the rapid development of neural networks in recent years makes them an effective tool for modal parameter identification. In this paper, a moving mass beam simulation model is established to simulate the time-varying characteristics of the structure, and the modal parameters of the dynamic strain signal are identified. The comparison results of three identification methods are obtained.
Bracket design and natural frequency analysis of civil aircraft inertial reference unit
Authors: Lan Xinghai , Liu Qiang 
Published: December 2023

Abstract
The Inertial Reference Unit (IRU) is an important and indispensable airborne equipment for civil aircraft, which is used to provide information on aircraft attitude, heading, acceleration and so on. The design of its bracket will directly affect the signal accuracy of the equipment. In order to ensure the accuracy of the information of the measuring equipment, the stiffness design of the support has strict requirements to avoid the impact of vibration and elastic deformation on the accuracy of the output signal. Through theoretical formula derivation and finite element analysis, this paper summarizes the influence of different bracket structure forms on the natural frequency and obtains the scheme to improve the natural frequency of the bracket. By increasing the flange height, adjusting the lightening hole on the plane mounting plate of the bracket and making the plane mounting plate, frame and skin form a box-shaped structure, the torsional stiffness of the bracket is enhanced. The results show that the improved bracket meets the requirements of natural frequency which is greater than 110 Hz, which can provide a reference for the design and strength analysis of similar aircraft airborne equipment.

Referring to the KT equation of ship maneuverability, the paper established the maneuverability KT equation of the amphibious aircraft on the water surface, and the parameters in the KT equation of amphibious aircraft were identified by forward difference. The test results show that the average value of K value is -0.1095, and the average value of T value is 0.5490. The turning efficiency of amphibious aircraft is low, the maneuverability is insufficient, and the heading stability is good. At the same time, the steering response is fast and the delay is low.

Authors: Liu Yuqi , Jiang Qirui , Dang Wanli , Luo Qian , Zheng Jiaoling 
Published: December 2023

Abstract
The aircraft and special vehicles in the aircraft turnaround milestone have the characteristics of large-scale difference, small spacing distance, etc., and many external interference factors result in many occlusion situations in the process of services. Aiming at the problem that existing airport detection algorithms are ineffective in detecting occluded targets in milestones, an improved YOLOv7 occluded target detection algorithm for aircraft turnaround milestones is proposed. The algorithm adds an efficient channel attention mechanism to the backbone network to suppress the interference information in the environment and improve the attention to the important channels and replaces the convolution in the feature fusion network with a double-pooled coordinate convolution, which is used to improve the model’s ability to extract the spatial information of the occluded target and the remaining features. The algorithm achieves an average detection precision of 89.7% and a recall rate of 88.3% on the aircraft turnaround milestone dataset covering numerous occlusion scenarios, which are 6.1% and 4.4% higher than the YOLOv7 algorithm, respectively. The experiments show that the algorithm can better cope with the task of occlusion target detection in aircraft turnaround milestones.
Bolt looseness identification using a knocking acoustic signal
Authors: Hao Bin , Su Yuelong , Yan XianFeng , Zhao Yitao 
Published: December 2023

Abstract
As a common failure form of the bolted joint, bolt looseness can lead to relative slip between the connected surfaces. Under the action of shear external forces, the bolt experiences fatigue failure and fracture, which can affect the service performance and connection strength of the equipment, and even cause major safety accidents. At present, good results have been achieved in detecting the tightness of bolt connections through Structural Health Monitoring (SHM) technology. However, most of them are still carried out under laboratory conditions and cannot be applied in engineering. Therefore, this article proposes looseness recognition of bolts by knocking acoustic signals. This method converts the acoustic time series signal into a Mel-Frequency Cepstral Coefficient (MFCC) frequency spectrum and then it recognizes the bolt looseness status through the Mobilenetv3 deep neural network. The results show this method can identify loose bolts. Meanwhile, it has a strong engineering application background.

Published: December 2023

Abstract
To evaluate the effect of the compressor rotor blade on compressor blade fatigue, a non-contact dynamic stress measurement scheme of one aero-engine eighth stage compressor rotor blade was designed, and the dynamic stress test was carried out. Meanwhile, modal analysis of the eighth stage compressor rotor blade was done by finite element analysis software. Results show that between the range of the idle speed and the highest speed, there is no resonance for the eighth stage compressor rotor blade and the maximum vibration amplitude is less than 65 μm, which cannot result in high cycle fatigue failure.

Aerial refueling rendezvous routes for UAVs based on nonlinear guide laws
Authors: Wang Yipeng , Song Yujian , Zhang Deyue , Wang Guanglin 
Published: December 2023

Abstract
The route fusion rendezvous strategy is mostly used for air refueling within the safety zone, with fewer restrictions on the rendezvous airspace. There are fewer restrictions on the combined airspace. The refueling aircraft follows a set route, and the UAV gradually converges with the refueling aircraft by adjusting its own course. The UAVs gradually merge with the fueler’s route until they track the fueler to a certain distance behind the fueler and synchronize with the fueler’s status. The subsequent docking process is carried out.
The fused route design is analogous to the use of missiles to track and strike moving targets. The unmanned aircraft are treated as pursuers moving at high speed. The fueling aircraft are treated as targets moving in a fixed pattern to be returned. The main objective of the convergent route design is to draw on and select appropriate guidance laws to bring the unmanned aircraft close to the fuel tanker. The main objective of the route fusion design is to use and select a suitable guidance law that allows unmanned aircraft to approach the fueling aircraft and achieve autonomous rendezvous. The traditional navigation laws are Pure Pursuit (PP) and Proportional Navigation (PP). The basic idea is to change the speed vector of a drone by varying its size. The difference is that the pure tracking guidance law requires the speed vector of the drone to coincide with the line of sight. In contrast, the example guidance law starts from the fact that the angular rate of rotation of the drone’s speed vector and the ratio guiding law is to keep the angular rate of rotation of the speed vector of the drone and that of the target in a fixed proportion.
