Development of the book distribution system of the People's Republic of China
Authors: Shuaitian Wan 
Published: June 2024

It is substantiated that an important means of overcoming the consequences of the pandemic in the book industry is its further digital transformation. It is noted that there are no publications that would give a complete picture of the main stages of digital transformations in the book distribution system of the People's Republic of China. It was concluded that the theoretical generalization of the evolution of the introduction of digital technologies into the book distribution system of the People's Republic of China is essential. The development of the book distribution system of the People's Republic of China was analyzed in the context of the main stages of digital transformation. The relationship between the terms "digitization", "digitalization", "digital transformation" is considered. Analysis of sources by research topic demonstrates that the relationship between these terms evolves over time. So, at first digital transformation was called what we now call digitization, i. e. conversion from analog to digital, then it became called digitalization. This is due to the different spectrum of views on the origins of this phenomenon.
The main stages of the digital transformation of the book distribution system of the People's Republic of China are highlighted. At the first stage — the 90s of the XX century — the process of digitization of publications began and that became a prerequisite for the creation of digital libraries and collections, the use of the Internet to provide access to digitized content, as well as for the development of electronic commerce. The second stage — from 2000 to 2010 — is characterized by the beginning of the development of electronic book publishing and electronic book trade. The third stage — 2010—2020 — contains the development of book distribution through mobile devices, the emergence of digital distribution platforms, which gradually use the latest achievements in the field of information and communication technologies (ICT), such as cloud technologies, Big Data technologies, and artificial intelligence in their activities.

The demand for monitoring activities has been more evident recently in oil and gas “O & G” activities such as exploration, drilling, production, logistics, or shipping. Consequently, these offshore infrastructures require asset management (or facilities management). This study seeks to understand the research pattern of publications within the domain of asset management in offshore infrastructures with the aim of determining the present state of the field’s research. The paper conducts a scientometric analysis of publications that focus on offshore infrastructures’ asset management published between 1992 and 2022. The employed search query yielded a total of 346 journal articles from the Scopus database and 43 from the Web of Science (WoS) database, respectively. The data analysis of the scientometric investigation explored research authorship, co-occurrence of keywords, number of publications, network mapping, country geographical breakdown, and literature coupling. The paper shows rising interest in monitoring and asset management in the oil and gas industry. It was concluded that the management of these infrastructures requires frequent review with the application of sustainable asset management strategies.

Published: June 2024

Liquid smoke is produced by the pyrolysis of biomass. The use of liquid smoke has numerous advantages over traditional smoking methods. The liquid smoke market is well-established and growing, providing an opportunity to commercialize biomass pyrolysis. This study aimed to investigate the utility of durian rind, biomass waste rich in lignin, cellulose, and hemicellulose, as a natural preservative to extend the shelf life of chicken meatballs and to mitigate environmental problems caused by the disposal of untreated durian rind waste. Dried durian rinds with approximately 10% water content were pyrolyzed at temperatures of 300°C (T1 liquid smoke), 340°C (T2 liquid smoke), and 380°C (T3 liquid smoke) using a slow pyrolysis reactor in batch conditions to produce crude liquid smoke, which was then purified by distillation at 190°C. Chicken meatballs were then soaked in liquid smoke solutions with concentrations of 1%, 2%, and 3% for 15 minutes, and the meatballs checked for signs of spoilage every 4 hours. Tests for total volatile base nitrogen (TVB-N), in addition to the total plate count (TPC) and most probable number (MPN) of Escherichia coli bacteria, were performed to evaluate the preservation ability of the liquid smoke. The results indicated that both the pyrolysis temperature and liquid smoke concentration affected the preservation time, with a pyrolysis temperature of T3 and liquid smoke concentration of 3% optimum for chicken meatball preservation. Under these conditions, the meatballs could be stored for 56 hours with TVB-N, TPC, and E. coli MPN values of 21.01 mg N/100 g, 5.37 × 104 CFU/g, and 75 MPN/g, respectively. The findings suggest that liquid smoke derived from durian rinds could be used to preserve chicken meatballs.

Time-varying mesh stiffness calculation and dynamic modeling of spiral bevel gear with spalling defects
Authors: Li Keyuan , Qiao Baijie , Fang Heng , Yang Xiuyue , Chen Xuefeng 
Published: June 2024

Time-varying mesh stiffness (TVMS) is a vital internal excitation source for the spiral bevel gear (SBG) transmission system. Spalling defect often causes decrease in gear mesh stiffness and changes the dynamic characteristics of the gear system, which further increases noise and vibration. This paper aims to calculate the TVMS and establish dynamic model of SBG with spalling defect. In this study, a novel analytical model based on slice method is proposed to calculate the TVMS of SBG considering spalling defect. Subsequently, the influence of spalling defect on the TVMS is studied through a numerical simulation, and the proposed analytical model is verified by a finite element model. Besides, an 8-DOF dynamic model is established for SBG transmission system. Incorporating the spalling defect into TVMS, the dynamic responses of spalled SBG are analysed. The numerical results indicate that spalling defect would cause periodic impact in time domain. Finally, an experiment is designed to verify the proposed dynamic model. The experimental results show that the spalling defect makes the response characterized by periodic impact with the rotating frequency of spalled pinion.

Return Currents in Collisionless Shocks
Authors: Gupta Siddhartha , Caprioli Damiano , Spitkovsky Anatoly 
Published: June 2024

Abstract
Collisionless shocks tend to send charged particles into the upstream, driving electric currents through the plasma. Using kinetic particle-in-cell simulations, we investigate how the background thermal plasma neutralizes such currents in the upstream of quasi-parallel non-relativistic electron–proton shocks. We observe distinct processes in different regions: the far upstream, the shock precursor, and the shock foot. In the far upstream, the current is carried by nonthermal protons, which drive electrostatic modes and produce suprathermal electrons that move toward upstream infinity. Closer to the shock (in the precursor), both the current density and the momentum flux of the beam increase, which leads to electromagnetic streaming instabilities that contribute to the thermalization of suprathermal electrons. At the shock foot, these electrons are exposed to shock-reflected protons, resulting in a two-stream type instability. We analyze these processes and the resulting heating through particle tracking and controlled simulations. In particular, we show that the instability at the shock foot can make the effective thermal speed of electrons comparable to the drift speed of the reflected protons. These findings are important for understanding both the magnetic field amplification and the processes that may lead to the injection of suprathermal electrons into diffusive shock acceleration.

Published: June 2024

Abstract
We examine the evolution of the disk surrounding the Be star in the highly eccentric 10.8 yr binary system δ Scorpii over its three most recent periastron passages. V-band and B − V photometry, along with Hα spectroscopy, are combined with a new set of extensive multiband polarimetry data to produce a detailed comparison of the disk's physical conditions during the time periods surrounding each closest approach of the secondary star. We use the three-dimensional Monte Carlo radiative transfer code HDUST and a smoothed particle hydrodynamics code to support our observations with models of disk evolution, discussing the behavior of the Hα and He i 6678 Å lines, V-band magnitude, and polarization degree. We compare the characteristics of the disk immediately before each periastron passage to create a baseline for the unperturbed disk. We find that the extent of the Hα emitting region increased between each periastron passage, and that transient asymmetries in the disk become more pronounced with each successive encounter. Asymmetries of the Hα and He i 6678 Å lines in 2011 indicate that perturbations propagate inward through the disk near periastron. When the disk’s direction of orbit is opposite to that of the secondary, the parameters used in our models do not produce spiral density enhancements in the Hα emitting region because the tidal interaction time is short due to the relative velocities of the disk particles with the secondary. The effects of the secondary star on the disk are short-lived and the disk shows independent evolution between each periastron event.
Thermal Structure Determines Kinematics: Vertical Shear Instability in Stellar Irradiated Protoplanetary Disks
Authors: Zhang 张 Shangjia 尚嘉 , Zhu 朱 Zhaohuan 照寰 , Jiang 姜 Yan-Fei 燕飞 
Published: June 2024

Abstract
Turbulence is crucial for protoplanetary disk dynamics, and vertical shear instability (VSI) is a promising mechanism in outer disk regions to generate turbulence. We use the Athena++ radiation module to study VSI in full and transition disks, accounting for radiation transport and stellar irradiation. We find that the thermal structure and cooling timescale significantly influence VSI behavior. The inner rim location and radial optical depth affect disk kinematics. Compared with previous vertically isothermal simulations, our full disk and transition disks with small cavities have a superheated atmosphere and cool midplane with long cooling timescales, which suppresses the corrugation mode and the associated meridional circulation. This temperature structure also produces a strong vertical shear at τ
* = 1, producing an outgoing flow layer at τ
* < 1 on top of an ingoing flow layer at τ
* ∼ 1. The midplane becomes less turbulent, while the surface becomes more turbulent with effective α reaching ∼10−2 at τ
* ≲ 1. This large surface stress drives significant surface accretion, producing substructures. Using temperature and cooling time measured/estimated from radiation-hydro simulations, we demonstrate that less computationally intensive simulations incorporating simple orbital cooling can almost reproduce radiation-hydro results. By generating synthetic images, we find that substructures are more pronounced in disks with larger cavities. The higher velocity dispersion at the gap edge could also slow particle settling. Both properties are consistent with recent near-IR and Atacama Large Millimeter/submillimeter Array (ALMA) observations. Our simulations predict that regions with significant temperature changes are accompanied by significant velocity changes, which can be tested by ALMA kinematics/chemistry observations.
