Powering life through MitoTechnologies: exploring the bio-objectification of mitochondria in reproduction
Authors: Bühler Nolwenn , Herbrand Cathy 
Published: September 2020

AbstractMitochondria, the organelles providing the cell with energy, have recently gained greater public visibility in the UK and beyond, through the introduction of two reproductive technologies which involve their manipulation, specifically ‘mitochondrial donation’ to prevent the maternal transmission of inherited disorders, and ‘Augment’ to improve egg quality and fertility. Focusing on these two ‘MitoTechnologies’ and mobilising the conceptual framework of “bio-objectification”, we examine three key processes whereby mitochondria are made to appear to have a life of their own: their transferability, their optimisation of life processes and their capitalisation. We then explore the implications of their bio-objectification in the bioeconomy of reproduction. Drawing on publicly available material collected in two research projects, we argue that mitochondria become a biopolitical agent by contributing to the redefinition of life as something that can be boosted at the cellular level and in reproduction. Mitochondria are now presented as playing a key role for a successful and healthy conception through the development and promotion of MitoTechnologies. We also show how their “revitalising power” is invested with great promissory capital, mainly deriving from their ethical and scientific biovalue in the case of mitochondrial donation, and from the logics of assetisation, in the case of Augment.

Published: September 2020

Abstract
This study introduces a simple method that enables cross-sectional visualization in the measurement of the planer-laser induced fluorescence (PLIF) method. The concentration field of the high Schmidt number scalar mixing layer generated by grid-generated turbulence is measured by a water-channel experiment in this tudy. The high Schmidt scalar mixing layer is produced by Rhodamine B aqueous solution and water. A small transparent prism, installed on the outside wall of the test section, aids in applying cross-sectional visualization. The small transparent prism is an isosceles triangular shaped prism filled with the working fluid through the test section of the water channel. The setting and details of the small transparent prism are shown in this study. By using the small transparent prism, the concentration field on the plane set into the test section is shown as a result of the cross-sectional visualization. In this result, a scalar structure like a mushroom is visualized around the mixing interface of the scalar mixing layer, as found in a previous experiment.

Authors: Wen Zhigang , Lv You , Li Shan , Liu Dan 
Published: September 2020

Abstract
In this paper, we consider a two-way relaying channel with simultaneous wireless information and power transfer. The intermediate relay station forwards lattice codes under transmit power constraint. Meanwhile, it charges user terminals for static circuit consumption and uplink transmission power. We novelly propose an iterative algorithm to maximize the sum-rate with joint beam-forming and power splitting design in MPT assisted TWRC. The method achieves the highest achievable rate compared with separate optimization designs and time switching method. Moreover, an extremely small gap between the proposed method and the outer cut-set bound is observed.

Abstract
Aerodynamic shape optimization of natural-laminar-flow (NLF) nacelle for lange-range wide-body transport aircraft was investigated. Perturbed class function/shape function transformation (CST) method was used to parameter the three typical generatrix of the nacelle combined with the perturbation based transfinite interpolation method to achieve surface and space grid update. The k-ω SST (shear stress transport) turbulence model and ϒ – Re
θ transition models was use to predict the transition location.The gradient based optimization method called Sequential Quadratic Programming was selected for the high efficiency. Natural laminar flow design was performed on three dimensional nacelles and about 45%∼55% laminar flow region was achieved by the optimization design.

Authors: Tao Yang , Xiong Neng , Huang Kang , Wu Junqiang 
Published: September 2020

Abstract
Based on the analysis of aerodynamic load and structural strength of the vehicle contact network monitoring device, the distribution of aerodynamic moments and surface pressure of the monitoring device is calculated by means of fluid-solid coupling. The calculated load is applied to the surface of the device for structural analysis, mainly to investigate the maximum deformation and maximum equivalent stress of the device. The study found that air flow separation occurred above the ear region when driving forward, the pressure was higher, and the air flow below the ear region flowed around the ear region. The pressure difference between the upper and lower ears produced a downward force of about 150N in a single ear region, and produced a large rolling moment, after checking its connection strength with the central body to meet the requirements for use.

Authors: Liu Jiali , He Guanda , Wang Hongyan 
Published: September 2020

Abstract
Studying the ultra-high energy gamma ray source is an important way to reveal the origin of the cosmic ray, which is also a main topic of many ground gamma ray experiments. To expect the observation ability during the design of the experiment, as well as to test the analyse methods in the observation, a Monte Carlo procedure for the signal and background generation is necessary. In this paper, such a procedure is introduced. And the source significance for a Blazar source Mrk421 is expected based on this procedure. Finally, an unfolding method for the source spectrum measurement is also established bashed on this Monte Carlo data, which gives fitting errors around ±10.0% both for the flux and the spectrum index.

The problem of quantitative assessment of soil pollution of the capital metropolis by controlling physical-chemical factors of solid and liquid phases of soil is investigated. The metals were used as an integral indicator of pollution taking into account the mass fraction and the variation of soil bulk density. Multiple regression (R2=0.91-0.95) of layered heavy metals, as well as accumulation of biophilic elements of the exchange fund from two main predictors – dispersion (effective specific surface area of solid phase, determined by the original thermal desorption method) and pH of salt extract was revealed.
A Bayesian estimation-based uncertainty quantification of flaws in steel welds detected by ultrasound phased array
Authors: He Jingran , Chen Zhijian , Luo Xuhui 
Published: September 2020

Abstract
Phased array ultrasonic scanning is currently the most advanced non-destructive test for detecting flaws in a steel welding. However, large uncertainty exists in the detection results. Technically, this uncertainty is induced by the sparsity of detection resolution compared to the scale of the flaws. Consequently, it is essential to enrich the resolution of detection results and quantify the corresponding statistical uncertainty before evaluating the number and equivalent of the flaws in the steel welding. In this paper an uncertainty quantification framework is built with Bayesian compressive sensing method from which the equivalent of the flaws in the steel welding with certain degree of confidence can finally be given.
Effects of chlorine atoms doping on the electronic structure of monolayer molybdenum disulfide
Authors: Wang Ruoxin 
Published: September 2020

Abstract
Two dimensional materials have special properties including small size effect, surface effect and quantum confinement effect caused by limited dimensionality, and their energy band can be tuned while doping by impurity elements. Recently, two dimensional transition metal dichalcogenides (TMDCs) are thought to be the most prospective material to fit Moore’s law. Among them, MoS2 is the most common and important materials in research and it might have the best photoelectric property among all known two dimensional materials. In this article, we simulated n-doped monolayer MoS2 with chlorine atoms with the method of density functional theory and studied the effect on its electronic structure like electronic density of states and energy band structures. The results showed that this chlorine doping can introduce a defect energy level in the band structure of the monolayer MoS2 and make it become n-type semiconductor. Our work lays a foundation for further research on the doping of other two-dimensional materials besides MoS2 together with the study on the materials’ electronic structure.

Authors: Shen Meie , Gao Xingle , Peng Minfang 
Published: September 2020

Abstract
With the development of cyber-physical power system, cyber security has a serious impact on the operation of power system. In this paper, a stochastic cascading failure model considering the structural and dynamical characteristics of cyber-physical power system is proposed. The model takes into account the community structure of networks, the heterogeneity of network nodes and the complex interdependence of coupling networks. Moreover, the malware spreading in the cyber network and the power flow redistribution in the power grid are considered to describe the dynamic physical processes of the system, and a stochastic method is adopted to describe the operating state transition of network components. Simulation results indicate that the cascading failure of coupled system is the result of malware attacks repeatedly triggering the power grid, and cyber coupling will aggravate the severity of grid failure propagation.

Published: September 2020

Abstract
This paper focuses on the issue of how to select the optimal deployment scheme for the dispersal of miss distance during acoustic rendezvous measurements. Firstly, the measurement theory of acoustic rendezvous is introduced, and then the error model of acoustic rendezvous measurement is deduced and theoretical analysis is carried out. Then, an error evaluation index is established based on the dispersion characteristics of miss distance. Finally, simulation experiments are conducted for the miss distance obeying uniform distribution and normal distribution. Simulation experiments verify the correctness of the method in this paper, which has important guiding significance for the miss distance test.

Authors: Liu Guangyuan , Chen Xuekong , Guo Qiuting , Shi Xiaojun 
Published: September 2020

Abstract
The range of Mach number of 1.3 to 1.5 is defined as low-supersonic flow in wind tunnel testing, which is necessary range for major fighters, aerospace vehicles, and missiles to reach the cruise state. It is also the most difficult test range for conventional ground simulation equipment due to sound barrier and uniformity of artificial air flows. In order to expand the test range of 2.4m transonic wind tunnel, researches on low supersonic flow filed calibration was carried out, and the geometrical parameters of perforated walls in test section were determined. Measured results of flow uniformity are compared with advanced wind tunnels using cross-shaped rake and cone-cylinder model. The results show that uniformed low supersonic flow in model testing area was obtained using newly developed nozzle together with perforated walls in 2.4m transonic wind tunnel, which effectively improve the simulation capability of the facility. Together with the capacity of 2m supersonic wind tunnel, seamless link of test data has been achieved in high speed regime, which has formed an integrated test platform for sub-, trans-, and supersonic speeds on the order of 2 meters.
Influence of the conical seamount on underwater sound propagation in a 3D shallow sea environment
Authors: Xiao Rui , Zhu Hanhao , Xue Yangyang , Jiang Hui , Chen Chao , Zhu Jun 
Published: September 2020

Abstract
The sound field of a 3D shallow sea environment with a conical submarine mountain is simulated and calculated using the finite element method. To verify the accuracy of the finite element calculation results, the effects of submarine mountain height and sound source depth on sound-propagation characteristics are evaluated. The simulation results indicate that owing to the reflection and concentration of acoustic energy due to the submarine mountain, before the sound wave reaches the subsea mountain, the impact of subsea mountain on the acoustic energy can reach 10 dB. In addition, the sound energy is hindered by the seamount. Therefore, the sound energy loss after the sound wave reaches the subsea mountain is higher than the sound energy loss in the absence of the seamount under the same circumstance, and the maximum is up to 20 dB. The larger the seamount height and sound source depth, the more significant the blocking and accumulation of the sound energy.
Reconstructing the multicellular structure of a developing metazoan embryo with repulsion-attraction model and cell-cell connection atlas in vivo
Authors: Guan Guoye , Tang Lei-Han , Tang Chao 
Published: September 2020

Abstract
Embryogenesis is a spatio-temporal multicellular evolutional process involved with intracellular biochemical activities and intercellular biophysical interactions. Reproducible and precise multicellular structures contribute to robustness of embryonic development by cell-cell communication, morphogenesis and other significant biological events. Using Caenorhabditis elegans as animal model, recently several researches established mechanical models to reconstruct the multicellular structures of this developmental system, in which cells interact via repulsive or attractive potentials inside an ellipsoidal eggshell. However, those models ignored some practical details and lack of test in depth. In this paper, we improved an in silico modeling framework based on previous models by revising formulae of interactive force and applying in vivo experimental information of eggshell shape, cell volume, cell position and cell-cell connection relationship. Cell pairs with and without empirically repeated connection were regarded to have different types of attractive force, which could help stabilize cells into their experimentally observed locations accompanied by correct neighbour relationships. Both previous models and our revised ones were tested, verified and compared to each other. Our modeling framework not only reproduces the multicellular structure patterns in an artificially compressed embryo with ∼50 cells, but also exhibits a potential to uncover active adjustments and controls on cell positioning.
Research on rapid planning of intelligent aircraft trajectory under multiple constraints
Authors: Li Fangfang , Li Zuozhi 
Published: September 2020

Abstract
Intelligent aircraft trajectory planning is an important support to ensure the successful completion of the mission of the aircraft, and it is also a key component of the intelligent aircraft mission planning system. Due to system performance constraints and environmental constraints, the positioning system of the intelligent aircraft cannot be accurately positioned during flight, which will cause flight errors. Excessive flight errors will lead to the failure of the mission. Therefore, error correction plays an increasingly important role in trajectory planning. This paper studies the rapid trajectory planning of intelligent aircraft under the limitation of system positioning accuracy. Based on the optimization theory, with the error generation rules and correction rules of the intelligent aircraft in flight as constraints, establishes the optimization model, and uses the fast non-dominated multi-objective optimization algorithm (NSGA-II) with elite retention strategy. This paper corrects the vertical and horizontal errors during the flight, and finally designs a reasonable intelligent aircraft trajectory that meets the minimum trajectory length and the minimum number of corrections during the flight.

Authors: Hu Shangwei , Tu Xiaobo , Li Meng , Chen Shuang , Yang Furong 
Published: September 2020

Abstract
CO in combustion products of aeroengine is a sign product of incomplete combustion. Real-time monitoring of CO can feedback combustion efficiency, which is of great significance to the design of combustion chamber and the optimization of fuel ratio of aeroengine. In this paper, based on the mid infrared absorption spectroscopy, a single optical path calibration-free wavelength modulation method is proposed to measure the temperature and concentration of CO in a flat flame. Firstly, the spectrum of light intensity signal and the amplitude frequency response of different frequencies are analysed, and the appropriate scanning frequency and modulation frequency are selected. Secondly, the equalization of Butterworth filter in DPLA is proposed to extract the first and second harmonics. The filter can effectively reduce the influence of nonlinear phase. Furthermore, calibration-free wavelength modulation method is simulated to measure CO at different temperature and concentration. Finally, CO in flat flame with different equivalence ratio at 5mm was measured for verification. The relative error between the measurement results of calibration-free wavelength modulation and that of thermocouple measurement is within 3.6% in the range of concentration 0.11% ∼ 0.24%, which verified the feasibility and effectiveness of the measurement scheme, and provided a reference for the CO concentration measurement at the outlet of aeroengine.

Authors: Li Hongyang , Huang Wei , Zhang Wentao , Yin Shan 
Published: September 2020

Abstract
We demonstrate an active controlled electromagnetically induced transparency (EIT) device via thermal control in a hybrid metamaterial, which consists of two split-ring resonators (SRRs) with integrated InSb-metal and a cut wire (CW) in a unit cell. We can dynamically control the amplitude modulation of the EIT window, by varying the temperature of the InSb thereby changing the damping rate of the dark mode of SRRs. When the temperature of the InSb changes from 240K to 320K, the EIT window undergoes modulation from on to off, and the modulation depth reaches 86.8%. The results are not only promising in designing compact slow light devices in the terahertz regime but also leading some essential applications in terahertz communications.

Published: September 2020

Abstract
Using covalent organic frameworks (COFs) to capture noxious gas has become an increasing research interest, especially for the purpose of environmental protection. A theoretical study on the interactions of carbon monoxide (CO), sulfur dioxide (SO2) and nitric oxide (NO), respectively with COF-300 has been proposed, based on the theory of the continuum approximation using Lennard-Jones potential. We discover that COF-300 can store more SO2 in comparison to CO and NO under an increasing pressure at 77K. The present methodology is computationally efficient and can be employed in other types of gases and nano-porous materials without conceptual difficulties.
