The horror of communication
Authors: Jutel Olivier 
Published: October 2022

AbstractThis article is concerned with the Lacanian subject of cyberwar and how the Real of network communication in the post-Trump era is experienced as horror. The centrality of the technological sublime and practices of self-divination to the American political imaginary give this moment of the Real a properly cosmic and spiritual scale. What returns are techno-horrors of intersubjective dread and the capitalist Real of the network in which we are fragmented and manipulated by occulted forces. The generalization of cyberwar shapes the liberal/populist entanglement between the hysteria of the disinformation expert and the perversion of the QAnon digital soldier.
Social sciences and humanities research funded under the European Union Sixth Framework Programme (2002–2006): a long-term assessment of projects, acknowledgements and publications

Published: October 2022

AbstractThe Framework Programmes for Research and Technological Development are funding programmes created by the European Union to support and foster research. This study aims to describe the features and assess the performance of Social Sciences and Humanities research projects funded under the Sixth Framework Programme that was active between 2002 and 2006. The results show that most funded projects were in the fields of economics and political sciences, in line with the use of the Framework Programme to enhance economic development and the integration process in Europe. Research teams showed a high level of collaboration with an average of 7.8 countries and 10.8 institutions involved in each project. However, the large size and diversity of consortia did not translate into a large number of co-authored scholarly journal articles. The results show that research funds in the Social Sciences and Humanities may have long-term effects, with some outputs acknowledging funding being published more than a decade after the end of the project. Qualitative analysis of the acknowledgements in the articles revealed four types of support: direct funding; utilisation of results from former funded projects as the basis for further research; involvement in conferences and networks resulting from funded projects; and utilisation of datasets or other products resulting from former funded projects. The study also illustrates the difficulties in retrieving the outputs resulting from funded projects since the funding information in Scopus is heterogeneous and not standardised. As a result, the type of assessment conducted in this project is time-consuming and requires a significant amount of manpower to clean and standardise the data. Nevertheless, the procedure could be applied to analyse the performance of subsequent European Framework Programmes in building a European Research Area in the Social Sciences and Humanities.

We describe a digital microwave platform called Presto, designed for measurement and control of multiple quantum bits (qubits) and based on the third-generation radio-frequency system on a chip. Presto uses direct digital synthesis to create signals up to 9 GHz on 16 synchronous output ports, while synchronously analyzing responses on 16 input ports. Presto has 16 DC-bias outputs, four inputs and four outputs for digital triggers or markers, and two continuous-wave outputs for synthesizing frequencies up to 15 GHz. Scaling to a large number of qubits is enabled through deterministic synchronization of multiple Presto units. A Python application programming interface configures a firmware for synthesis and analysis of pulses, coordinated by an event sequencer. The analysis integrates template matching (matched filtering) and low-latency (184–254 ns) feedback to enable a wide range of multi-qubit experiments. We demonstrate Presto’s capabilities with experiments on a sample consisting of two superconducting qubits connected via a flux-tunable coupler. We show single-shot readout and active reset of a single qubit; randomized benchmarking of single-qubit gates showing 99.972% fidelity, limited by the coherence time of the qubit; and calibration of a two-qubit iSWAP gate.

A new class of crystal shapes has been developed for x-ray spectroscopy of point-like or small (a few mm) emission sources. These optics allow for dramatic improvement in both achievable energy resolution and total throughput of the spectrometer as compared with traditional designs. This class of crystal shapes, collectively referred to as the Variable-Radii Spiral (VR-Spiral), utilize crystal shapes in which both the major and minor radii are variable. A crystal using this novel VR-Spiral shape has now been fabricated for high-resolution Extended X-ray Absorption Fine Structure (EXAFS) experiments targeting the Pb-L3 (13.0 keV) absorption edge at the National Ignition Facility. The performance of this crystal has been characterized in the laboratory using a microfocus x-ray source, showing that high-resolution high-throughput EXAFS spectra can be acquired using this geometry. Importantly, these successful tests show that the complex three-dimensional crystal shape is manufacturable with the required precision needed to realize the expected performance of better than 5 eV energy resolution while using a 30 mm high crystal. An improved generalized mathematical form for VR-Spiral shapes is also presented allowing improved optimization as compared to the first sinusoidal-spiral based design. This new formulation allows VR-Spiral spectrometers to be designed at any magnification with optimized energy resolution at all energies within the spectrometer bandwidth.
Syntactic outcomes of socially (un)restricted bilingualism in Spain
Authors: Gondra Ager 
Published: October 2022

Abstract
The present study uses the apparent-time construct to analyze cross-generational variability of word order in unergative and unaccusative constructions in Basque (e.g., negar ein ‘to cry’ and heldu ‘to arrive’, respectively). It considers the results of an acceptability judgment as well as elicitation tasks carried out among two generations of Basque native speakers (55–75 years old, and 35–45 years old). Unlike the younger participants, the older participants lack the syntactic focus strategy. It is proposed that this lack among the older participants was conditioned by the socially restricted bilingualism that they experienced during the dictatorship of Francisco Franco (1939–1975), while the younger participants appeared to have acquired (i.e. recovered) the syntactic focus strategy because they experienced the legitimacy and vitality of Basque in public life and in formal education following the Normalization Law of 1982. Studies in Basque sociolinguistics have identified language changes through feature loss, dialectal leveling and contact-induced change, but no studies to date have identified the recovery of a previously lost syntactic structure.
Nigerian stand-up comediennes performing femininity
Authors: Filani Ibukun 
Published: October 2022

Abstract
Nigerian stand-up comedy has attracted several investigations from different disciplinary perspectives; however,
there has been little research interest into the performance of femininity in the genre. Coming from pragmatics, this paper
analyses how Nigerian comediennes use the language of humour to (de)construct sociocultural perspectives on the female identity.
Data comprise purposively selected routines of three female comics while Kecskes’
(2014) approach to intention serves as the theoretical framework. Comediennes employ different pragmatic strategies
that reference their intention to reinforce or challenge the traditional image of femininity. Analysis reveals comediennes perform
the popular perspectives on femininity, which are enshrined in the wider sociocultural context of the country.
Utility of the W´BAL model in training programme design for masters cyclists
Authors: Galán‐Rioja Miguel Ángel , González‐Mohíno Fernando , Skiba Philip Friere , González‐Ravé José María 
Published: October 2022

ABSTRACTThe present study aims to determine the utility of integrating balance model (W´BAL‐INT) in designing interval training programmes as assessed by improvements in power output, critical power (CP), and W prime (W´) defined as the finite work capacity above CP. Fourteen male cyclists (age = 42 ± 7 yr, body mass = 69.6 ± 6.5 kg, height = 175 ± 5 cm, CP = 302 ± 32 W, relative CP = 4.35 ± 0.66 W·kg−1) were randomized into two training groups: Short‐Medium‐Long intervals (SML‐INT; n = 7) or Long intervals (L‐INT, n = 7) [training sessions separated by 72 h], along with 3–4 sessions of moderate intensity training per week, for 4 weeks. All sessions were designed to result in the complete depletion of the W´ as gauged by the W´BAL‐INT. CP and W´ were assessed using the specified efforts (i.e. 12, 7 and 3 min) and calculated with the 2‐parameter CP linear model. Training loads between the groups were compared using different metrics. CP improved in both the SML‐INT and L‐INT groups by 5 ± 4% and 6 ± 5% (p < 0.001) respectively, without significant changes in W´. Mean maximal power over 3, 7 and 12 min increased significantly in the SML‐INT group by 5%, 4% and 9%, (p < 0.05) without significant changes in the L‐INT group. There were no differences between groups in training zone distribution or training load using BikeScore and relative intensity, but there was significantly (p < 0.05) higher TRIMPS for the Long‐INT group. Therefore, W´BAL model may prove to be a useful tool for coaches to construct SML‐INT training programmes.
Integrable quenches in the Hubbard model
Authors: Rylands Colin , Bertini Bruno , Calabrese Pasquale 
Published: October 2022

Abstract
We study the quench dynamics of the one-dimensional Hubbard model through the quench action formalism. We introduce a class of integrable initial states—expressed as product states over two sites—for which we can provide an exact characterisation of the late-time regime. This is achieved by finding a closed-form expression for the overlaps between our states and the Bethe ansatz eigenstates, which we check explicitly in the limits of low densities and infinite repulsion. Our solution gives access to the stationary values attained by local observables (we show the explicit example of the density of doubly occupied sites) and the asymptotic entanglement dynamics directly in the thermodynamic limit. Interestingly, we find that for intermediate interaction strength Rényi entropies display a double-slope structure.
Influence of structural parameters of cartridge-type synchronous magnetic coupling on transmission performance
Authors: Yang Wen , Wu Rujun , Xu Zhongchao 
Published: October 2022

Abstract
The study of the structural parameters of the permanent magnet magnetic coupling is particularly important because they determine its transmission performance. In this paper, we first compare and analyze the results of theoretical calculation and simulation, and conclude that the calculation results of the 3D simulation model are closest to the actual situation. Maxwell software is used to study the effect of the cartridge type synchronous permanent magnet coupling on the transmitted torque at different working air gaps, permanent magnet thickness, yoke thickness, and aspect ratio under different pole numbers. The results show that: the increase of working air gap is not conducive to increasing the transmitted torque; the increase of permanent magnet thickness is beneficial to increase the transmitted torque, but the increase rate gradually decreases; the increase of yoke thickness has a small increase on the magnetic torque within a certain range, and the yoke thickness is slightly larger than the permanent magnet thickness is optimal; the increase of permanent magnet’s aspect ratio also increases the torque, and the torque density growth rate is the fastest when the aspect ratio is in the range of 0.5~0.7. Through the analysis, it is important for the design of synchronous magnetic coupling and other researches.

Measurement error analysis and accuracy improvement method based on gateway meter
Authors: Chen Kaiming , Deng Siyang , Li Wenjing 
Published: October 2022

Abstract
As the accuracy of the gateway meter is affected by various disturbances, it is necessary to analyze those influence factors intuitively. This paper introduces the main factors affecting the measurement accuracy and further proposes the improvement methods of the gateway meter. The influence factors are mainly on the aspects of the analog circuit, temperature, harmonics and ADC (Analog-to-Digital Converter), which will cause certain measurement error during the operation process of the gateway meter. Thus, the corresponding methods such as using high sampling rate of ADC and choosing appropriate voltage range are suggested to use. This paper provides a certain basis for improving the accuracy and reliability of the gateway meter.

Published: October 2022

Abstract
Loss of Actuator Effectiveness (LOE) reduces the performance parameters of Multi-rotor Unmanned Aerial Vehicle (UAV), which affects the reliability of the mission. However, in practice, researchers used to evaluate the performance of a UAV through lots of flight experiments or by experience, which is normally inefficient and costly. In order to evaluate the performance of UAVs, this paper presents a performance evaluation and analysis method under actuator LOE. First, models are established for the components of a propulsion system, mainly including actuators and batteries. Second, the performance evaluation problem is simplified and decomposed into two sub-problems. performance indices are established by kinetic analysis and then solved, considering the influence of actuator LOE and battery performance. Finally, based on the analysis results, the evaluation method is demonstrated in several cases. The results showed that the evaluation method is effective compared with the simulation results of www.flyeval.com/. In addition, LOE reduces the performance parameters of the UAV, which has a greater impact on the maximum flight speed and maximum cruising distance.
Analysis of hydraulic system’s weak fault based on variable parameter multi-scale permutation entropy and deep belief network
Authors: Jie Huang , Tao Fang , Chuanqi Cheng , Gaiyin Wu 
Published: October 2022

Abstract
Aiming at automatic recognition of hydraulic system’s weak fault, an analysis method based on variable parameter multi-scale permutation entropy (VPMPE) and deep belief network (DBN) is proposed in this paper. The external vibration signals of experimental hydraulic equipment in normal state and three different leakage state (slight, moderate and severe) are taken as research object. By the proposed method, experiment signals are first processed to obtain their multi-scale permutation entropy in different conditions by changing the embedding dimension m and the scale factor s, then the multi-scale permutation entropy under different m and s are combined to form feature vectors, and lastly the DBN classifier is used to identify and analyze the testing samples. Verification test shows that the proposed method has good effects on hydraulic system’s weak fault, which can accurately judge whether there is leakage fault and measure the fault severity.

Published: October 2022

Abstract
The abnormal operating conditions of pipeline equipment in natural gas compressor station, such as gas pipeline leakage or equipment failure, lead to negative social impacts. To solve the current problem of untimely and inaccurate manual maintenance, this study proposes a 24/7 real-time method for monitoring the operation of pipeline equipment in natural gas compressor station based on a spiral microphone array. First, the Linearly Constrained Minimum Variance (LCMV) beamformer is used to enhance the signal in the target angle direction and suppress the interference in other directions. Then we train the support vector machine (SVM) model based on the station’s Mel-Frequency Cepstral Coefficients (MFCC) feature dataset for diagnosis. The results show that the method is of great feasibility and reliability.

Authors: Zheng Hai , Yang Xi , Cai QiuShen , Wang JiChen , Li WenHui 
Published: October 2022

Abstract
Planetary roller screw is an important part of tree-climbing and pruning robot, and its vibration directly affects the safety of the whole machine. The ideality model of planetary roller screw was established based on TRIZ theory, which verified that the excellent performance of planetary roller screw was better than sliding screw and ball screw to a certain extent. The three-dimensional model was built by Proe, and the virtual prototype was built by ADAMS. The roller rotation speed and nut translation speed obtained by kinematics simulation were completely consistent with the theoretical value, which verified the accuracy of the virtual prototype. The natural frequency and vibration mode of planetary roller screw were obtained by ANSYS modal analysis. In practical applications, the natural frequencies of the components can be adjusted by modifying the relevant structural dimensions to avoid the possible resonance of the system or reduce the system vibration. The structural rigidity of the tree-climbing and pruning robot can be improved by appropriate modification of the planetary roller screw structure.
Research on ultrasonic testing method of rotating component based on a 6-DOF robot
Authors: Zhang Rongfan , Li Hongwei , Zheng Ying , Zuo Xin 
Published: October 2022

Abstract
Some rotating components have the structural characteristics of variable thickness and variable curvature. The conventional ultrasonic testing is inappropriate for these components because of bad coupling and too many uncertainties. In order to meet the testing requirements of high-volume, high-efficiency and high-precision, the corresponding ultrasonic automatic detection program is proposed. A 6-DOF industrial robot is used to realize the precise control of the transducer position and posture, and combines the independent turntable to complete the spiral fast scan of the specimen. Based on the multi-Gaussian beam model and the internal flat-bottom hole flaw scattering model of specimen, the flaw ultrasonic measurement model is established. The system parameters, component material parameters and component surface parameters are all introduced to the ultrasonic measurement model to generate a series of flaw-sizing curves. An accurate flaw sizing method based on DGS(Distance-Gain-Size)curve predicted by regular reflector is proposed. The scanning experiment results of the reference specimen show that the minimum Ø 0.8mm artificial flat-bottom-hole flaw in the workpiece can be detected effectively, and the sizing error is less than Ø 0.3mm equivalent.

Abstract
The specific impulse is one of the important parameters of the shock wave. The shock wave specific impulse test method based on the momentum block is an important method to measure the shock wave specific impulse. In this paper, by carrying out the simulation research on the impact response of the momentum ball and the spring-mass system, the maximum compression displacement of the spring under different loading speeds is linear, and it is feasible to use the spring-mass system as the carrier to measure the shock wave specific impulse.
Eddy Current Magnetic Field Analysis of Disk Synchronous Magnetic Coupler
Authors: Xu Zhongchao , Wu Rujun , Yang Wen 
Published: October 2022

Abstract
Aiming at the problem that the eddy current loss generated by the metal isolation sleeve of the disc type synchronous magnetic coupler affects its transmission performance, this paper firstly deduces the equation of eddy current loss from the theory, then analyzes the influence of the difference in rotation angles and rotation speed on the eddy current loss, and also studies the influence of the induced magnetic field generated by the eddy current on the air gap magnetic field. Through simulation, it is concluded that: the smaller the difference in turning angle or the larger the rotational speed produces the greater eddy current loss; the influence of the induced magnetic field on the air gap magnetic field is different from different turning angles differences. The conclusion is of guiding significance to reduce the eddy current loss and improve the transmission performance of the magnetic coupler.
