An enhanced genetic algorithm for unmanned aerial vehicle logistics scheduling
Authors: Yuan Xiaoxiang , Zhu Jie , Li Yixuan , Huang Haiping , Wu Min
Published: February 2021

This paper examines a scheduling problem with heterogeneous logistics unmanned aerial vehicles (UAVs) in urban environment. Different from traditional vehicle routing problem (VRP), it introduces some new characteristics such as the loading capacity, the maximum flight time and the flight speed. As a variant of VRP, the considered scheduling problem is known to be an non‐deterministic Polynomial (NP)‐hard problem. The UAV scheduling problem model with the heterogeneous UAV settings is formulated first. Secondly, a genetic‐based algorithm framework is presented for solving the scheduling problem, in which the encoding/decoding method, the initial population generation method and genetic operations are delicately designed. In order to reduce the search space and faster the execution of this algorithm, a weight‐based loading method is adopted. For the purpose of performance evaluation and statistical analysis, the proposed algorithm is compared with the other two existing algorithms. The experimental results show that the presented algorithm can solve this problem efficiently.

Published: February 2021

With the explosive growth of data communications, existing infrastructure networks are under ever‐increasing pressure. Due to the advantages of fully controllable mobility, rapid deployment, and low cost, the unmanned aerial vehicles (UAVs) have attracted much attentions from both industry and academia in recent years, and it has become an inevitable trend to employ UAVs to enhance the network performance in different environments. As an important paradigm of UAV‐assisted communications, UAV relaying communications has been regarded as a promising solution in enhancing connectivity and improving transmission rate. This paper for the first time comprehensively summarizes UAV relaying communications and its application scenarios, including single UAV relaying networks, multi‐user UAV relaying networks, multi‐hop UAV relaying networks, as well as Internet of UAVs, and deeply analyzes the key technologies and challenges to be solved under this topic. Furthermore, the state‐of‐the‐art researches and opportunities of UAV relaying communications are discussed in detail.
Transient energy protection based on wavelet packet transform for hybrid bipolar HVDC transmission system
Authors: Gao Shuping , Song Xiaochen , Ye Huanfei , Jiang Lin , Song Guobing
Published: February 2021

In hybrid bipolar DC transmission systems with different types of converters at each pole, the transient high‐frequency component of the voltage signal under a single‐pole grounding fault and an inter‐pole fault is significantly different for internal and external faults because of smooth‐wave reactors on both sides of the DC line. Based on these characteristics, a single‐ended electrical quantity protection scheme based on transient energy is proposed. First, the voltage fault component is extracted and then processed by using a wavelet packet transform to obtain the transient energy in each frequency band. Second, the protection criterion is determined based on the ratio between low‐frequency energy and the sum of high‐frequency energy. After the setting principle is given, the influence of the protection scheme under high transition resistance is analysed. The protection scheme is implemented in MATLAB and tested based on fault data obtained from a hybrid bipolar HVDC transmission model built in PSCAD under different operating conditions. The effectiveness of the proposed protection method is verified by simulation tests under different fault types at different fault distances. The proposed method can provide strong tolerance to high transient resistance, accurately identify internal/external faults and automatically identify fault poles.

Published: February 2021

Aims. SPIRou is a near-infrared (nIR) spectropolarimeter at the CFHT, covering the YJHK nIR spectral bands (980−2350 nm). We describe the development and current status of the SPIRou wavelength calibration in order to obtain precise radial velocities (RVs) in the nIR.

Methods. We make use of a UNe hollow-cathode lamp and a Fabry-Pérot étalon to calibrate the pixel-wavelength correspondence for SPIRou. Different methods are developed for identifying the hollow-cathode lines, for calibrating the wavelength dependence of the Fabry-Pérot cavity width, and for combining the two calibrators.

Results. The hollow-cathode spectra alone do not provide a sufficiently accurate wavelength solution to meet the design requirements of an internal error of < 0.45 m s−1, for an overall RV precision of 1 m s−1. However, the combination with the Fabry-Pérot spectra allows for significant improvements, leading to an internal error of ∼0.15 m s−1. We examine the inter-night stability, intra-night stability, and impact on the stellar RVs of the wavelength solution.
Quantifying the fine structures of disk galaxies with deep learning: Segmentation of spiral arms in different Hubble types
Authors: Bekki K.
Published: February 2021

Context.Spatial correlations between spiral arms and other galactic components such as giant molecular clouds and massive OB stars suggest that spiral arms can play vital roles in various aspects of disk galaxy evolution. Segmentation of spiral arms in disk galaxies is therefore a key task when these correlations are to be investigated.

Aims.We therefore decomposed disk galaxies into spiral and nonspiral regions using the code U-Net, which is based on deep-learning algorithms and has been invented for segmentation tasks in biology.

Methods.We first trained this U-Net with a large number of synthesized images of disk galaxies with known properties of symmetric spiral arms with radially constant pitch angles and then tested it with entirely unknown data sets. The synthesized images were generated from mathematical models of disk galaxies with various properties of spiral arms, bars, and rings in these supervised-learning tasks. We also applied the trained U-Net to spiral galaxy images synthesized from the results of long-term hydrodynamical simulations of disk galaxies with nonsymmetric spiral arms.

Results.We find that U-Net can predict the precise locations of spiral arms with an average prediction accuracy (Fm) of 98%. We also find thatFmdoes not depend strongly on the numbers of spiral arms, presence or absence of stellar bars and rings, and bulge-to-disk ratios in disk galaxies. These results imply that U-Net is a very useful tool for identifying the locations of spirals arms. However, we find that the U-Net trained on these symmetric spiral arm images cannot predict entirly unknown data sets with the same accuracy that were produced from the results of hydrodynamical simulations of disk galaxies with nonsymmetric irregular spirals and their nonconstant pitch angles across disks. In particular, weak spiral arms in barred-disk galaxies are properly segmented.

Conclusions.These results suggest that U-Net can segment more symmetric spiral arms with constant pitch angles in disk galaxies. However, we need to train U-Net with a larger number of more realistic galaxy images with noise, nonsymmetric spirals, and different pitch angles between different arms in order to apply it to real spiral galaxies. It would be a challenge to make a large number of training data sets for such realistic nonsymmetric and irregular spiral arms with nonconstant pitch angles.
The VLT-MUSE and ALMA view of the MACS 1931.8-2635 brightest cluster galaxy

Published: February 2021

We reveal the importance of ongoing in situ star formation in the brightest cluster galaxy (BCG) in the massive cool-core CLASH cluster MACS 1931.8-2635 at a redshift ofz = 0.35 by analysing archival VLT-MUSE optical integral field spectroscopy. Using a multi-wavelength approach, we assessed the stellar and warm ionised medium components, which were spatially resolved by the VLT-MUSE spectroscopy, and linked them to the molecular gas by incorporating sub-mm ALMA observations. We measured the fluxes of strong emission lines such as: [O II]λ3727, Hβ, [O III]λ5007, Hα, [N II]λ6584, and [S II]λ6718, 6732, which allowed us to determine the physical conditions of the warm ionised gas, such as electron temperature, electron density, extinction, ionisation parameter, (O/H) gas metallicities, star formation rates, and gas kinematics, as well as the star formation history of the system. Our analysis reveals the ionising sources in different regions of the galaxy. The ionised gas flux brightness peak corresponds to the location of the supermassive black hole in the BCG and the system shows a diffuse warm ionised gas tail extending 30 kpc in the north-east direction. The ionised and molecular gas are co-spatial and co-moving, with the gaseous component in the tail likely falling inward, providing fuel for star formation and accretion-powered nuclear activity. The gas is ionised by a mix of star formation and other energetic processes which give rise to LINER-like emission, with active galactic nuclei emission dominant only in the BCG core. We measured a star formation rate of ∼97 M⊙yr−1, with its peak at the BCG core. However, star formation accounts for only 50–60% of the energetics needed to ionise the warm gas. The stellar mass growth of the BCG atz < 0.5 is dominated either by in situ star formation generated by thermally unstable intracluster medium cooling or by dry mergers, with these mechanisms accounting for the build-up of 20% of the stellar mass of the system. Our measurements reveal that the most central regions of the BCG contain the lowest gas-phase oxygen abundance, whereas the Hαarm exhibits slightly more elevated values, suggesting the transport of gas out to large distances from the centre as a result of active galactic nuclei outbursts. The galaxy is a dispersion-dominated system that is typical for massive, elliptical galaxies. The gas and stellar kinematics are decoupled, with the gaseous velocity fields being more closely related to the bulk motions of the intracluster medium.

We present a chemo-dynamical study of the Orphan stellar stream using a catalog of RR Lyrae pulsating variable stars for which photometric, astrometric, and spectroscopic data are available. Employing low-resolution spectra from the Sloan Digital Sky Survey (SDSS), we determined line-of-sight velocities for individual exposures and derived the systemic velocities of the RR Lyrae stars. In combination with the stars’ spectroscopic metallicities andGaiaEDR3 astrometry, we investigated the northern part of the Orphan stream. In our probabilistic approach, we found 20 single mode RR Lyrae variables likely associated with the Orphan stream based on their positions, proper motions, and distances. The acquired sample permitted us to expand our search to nonvariable stars in the SDSS dataset, utilizing line-of-sight velocities determined by the SDSS. We found 54 additional nonvariable stars linked to the Orphan stream. The metallicity distribution for the identified red giant branch stars and blue horizontal branch stars is, on average, −2.13 ± 0.05 dex and −1.87 ± 0.14 dex, with dispersions of 0.23 and 0.43 dex, respectively. The metallicity distribution of the RR Lyrae variables peaks at −1.80 ± 0.06 dex and a dispersion of 0.25 dex. Using the collected stellar sample, we investigated a possible link between the ultra-faint dwarf galaxy Grus II and the Orphan stream. Based on their kinematics, we found that both the stream RR Lyrae and Grus II are on a prograde orbit with similar orbital properties, although the large uncertainties on the dynamical properties render an unambiguous claim of connection difficult. At the same time, the chemical analysis strongly weakens the connection between both. We argue that Grus II in combination with the Orphan stream would have to exhibit a strong inverse metallicity gradient, which to date has not been detected in any Local Group system.
A new diffuse-interface approximation of the Willmore flow
Authors: Rätz Andreas , Röger Matthias
Published: February 2021

Standard diffuse approximations of the Willmore flow often lead to intersecting phase boundaries that in many cases do not correspond to the intended sharp interface evolution. Here we introduce a new two-variable diffuse approximation that includes a rather simple but efficient penalization of the deviation from a quasi-one dimensional structure of the phase fields. We justify the approximation property by a Gamma convergence result for the energies and a matched asymptotic expansion for the flow. Ground states of the energy are shown to be one-dimensional, in contrast to the presence of saddle solutions for the usual diffuse approximation. Finally we present numerical simulations that illustrate the approximation property and apply our new approach to problems where the usual approach leads to an undesired behavior.

Authors: Xu Jia
Published: February 2021

With the advent of the blockchain era, employee incentives need to open up new ideas. The application of blockchain technology can promote the advantages of traditional equity incentive schemes and avoid weaknesses. Although there is still no mature ESOP on-chain solution on the market, and ESOP onchain still needs to consider a series of legal issues. The combination of equity incentives and blockchain technology is feasible. Due to the consensus mechanism of blockchain technology, grant and exercise information is recorded at each node on the chain. The implementation of the plan will be open and transparent throughout the process, avoiding the possibility of dark box operations. This is conducive to enhancing the credibility of the enterprise and enhancing employees’ trust in the enterprise, which can really play an incentive role.

Published: February 2021

In the “Internet+” era, conflicts of land requisition frequently occur. Existing research emphasizes the lack of systems but rarely considers the problems in the implementation of the system. Based on “Internet+”, this article adopts a case analysis method to discuss the governance of land requisition conflicts. This study analyzes the contradictions in the implementation of land acquisition, benefit distribution, procedures and information feedback. The dilemma of social governance stems from the “autonomous space”, “three-dimensional competition” and “independent space” of local governments.

Analysis of financial development and industrial structure transformation
Authors: Sun Shuwei Harold , Wang Allen , Yu Huan
Published: February 2021

This paper uses the relevant data from 2008 to 2017 to construct a multiple linear regression equation, and uses the generalized moment estimation model to explore the impact of financial development on industrial structure adjustment from the perspective of financial scale and efficiency. The results show that financial efficiency can promote the rationalization and upgrading of industrial structure, but the impact of financial scale on industrial structure is two-sided. Increasing financial scale can increase the amount of industrial financing and accelerate the process of industrial structure upgrading. However, blindly increasing the supply of loans will lead to the birth of bad investment, thus failing to promote the rationalization of industrial structure. Based on this, this paper puts forward some policy suggestions, such as promoting the diversified development of the financial industry, improving the imbalance of financial development in various provinces, promoting the reasonable investment structure and the development of high-tech industry, and giving full play to the role of the government.
Does Fiscal Transfer Improve the Equalization of Regional Public Health Service Evidence from a Spatial Panel-Data Analysis in China
Authors: Jin Youwen , Nong Guoping
Published: February 2021

Public health service is regarded a key social resource contributing to the national health and sustainable development. Its development gap, however, exists among regions in China due to the unbalanced regional economy, and is also affected by financial distribution. With the effect of tax reform, central fiscal transfer has become a strategic approach to narrow the regional gap of public health service and improve the regional development. This paper aims to evaluate provincial public health service levels in China by applying entropy method and shows that obvious spatial imbalance of public health service level exists in Chinese provinces and such imbalance is also consistent with that of average fiscal transfer from the central government to the regional ones. The current research also looks at, by adopting spatial panel model, a model developed from economic convergence model, whether central fiscal transfer effectively helps to lower the level of public health service difference in regions and the outcome depicts that central fiscal transfer, particularly fiscal transfer for specific purposes, accelerates Chinese public health service development especially in eastern, middle and western regions. From the perspective of spatial effect, neighborhood imitation effect exists to allow completion among neighboring regional governments and therefore more investment to public health service. Compared with the pace of economic development, central fiscal transfer’s limited effect is still seen in less developed regions particularly some midland and western areas, due to the inadequate investment rooted in government’s structured expenditure plan. The implication of this research is that, apart from the attention to economic growth, the government should, with the effort of fiscal transfer, financially focus more on the area of public health service.

R&D Investment Competition and Efficiency in a Mixed Duopoly Model, with Endogenous Spillover
Authors: Han Jie , Li Zelong
Published: February 2021

In this paper, a mixed duopoly model is used to explain how ownership structure influences the innovation performances of firms. A three stage-game is adopted in the study. In first stage, firms make R&D expenditure which leads to a profit increasing; in the second stage, firms choose the level of technological improvement they would like to share with the rival; and production quantity will be decided in the final stage. The theory explains that as long as public firms continue their dual roles as productive entities and social safety nets, they cannot be purely profit-oriented, and continue to have poor innovation performance.
