Yingtao Zhang,Yanchang Chen KOREA INSTITUTE FOR HUMANITIES AND SOCIAL SCIENCES 2023 Journal of Arts and Cultural Studies(ACS) Vol.2 No.2

Background: Laohekou New Year Pictures, dating back to the Ming and Qing Dynasties, is an important art in southern China. Due to development and inheritance crises in the 21st century, more social co-creation and social resources are needed to participate in the protection and inheritance of Laohekou New Year Pictures to promote their further sustainable development. Purpose: Protecting Laohekou New Year Pictures is full of prosocial behaviors, which is significant for developing these Pictures. This study analyzes the protection of Laohekou New Year Pictures based on the theory of prosocial behavior in social psychology. Methods: The protection behavior of Laohekou New Year Pictures was analyzed based on the theory of prosocial behavior, voluntarism, prosociality, and altruism. The four factors affecting the protection behavior were discussed, and relevant protection strategies were provided for future development. Results: This paper analyzes the characteristics and influencing factors of prosocial behavior of Laohekou New Year Pictures. It presents four strategies: "reducing the ambiguity of public responsibility participation", "giving full play to the driving force of opinion leaders", "strengthening the mechanism and system construction of rewards and punishments", and "skills popularization of New Year Picture heritage education". Conclusion: This paper combines the prosocial theory of social psychology with the intangible cultural heritage protection theory to conduct an interdisciplinary study. This study focuses on the four aspects of protection nature, protection subject, protection result and protection behavior embodied by the prosociality of Laohekou New Year Pictures. This makes the protection behavior of Laohekou New Year Pictures reflect the characteristics and influencing factors of prosocial behavior, and the related protection research permeates intangible prosocial behavior, which provides strategic guidance for the protection of intangible cultural heritage, provides future social support of altruism and public welfare for heritage inheritance, and further promotes the long-term development of Laohekou New Year Pictures.

Improvement of Resistive Switching Uniformity in TiO_x Film by Nitrogen Annealing

Yingtao Li,Yan Wang,Su Liu,Shibing Long,Hangbing Lv,Qin Wang,Sen Zhang,Ming Liu 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.58 No.3

The uniformity of resistive switching parameters is important to resistive random access memory (RRAM) device development. This work reports a remarkably improved uniformity of resistive switching parameters in atomic-layer-deposited titanium-oxide films. The broad variations of the resistive switching parameters in the as-deposited TiOx films can be improved by nitrogen annealing. Based on the results of the X-ray photoelectron spectroscopy (XPS) depth profile, the improved uniformity of resistive switching in the nitrogen-annealed TiO_x films may result from the higher density of oxygen vacancies in TiO_x films due to nitrogen annealing.

Superposition of structures in the Sichuan‒Yunnan N-S tectonic belt at the eastern margin of the Tibetan Plateau: constraints from structures and magnetic fabrics

Yingtao Chen,Guowei Zhang,Rukui Lu,Jinqiang Xie 한국지질과학협의회 2015 Geosciences Journal Vol.19 No.2

In this study on the northern section of the Sichuan– Yunnan tectonic belt (SYNSTB), which is on the eastern margin of the Tibetan Plateau, we assess the characteristics of superposed structures in the Daliang–Shan and Hanyuan–Ganluo fault belts, as well as in the Ganluo Basin that lies between them. By integrating field observations of structures with an analysis of magnetic fabrics, we show that the northern section of the SYNSTB underwent two episodes of deformation during the Mesozoic–Cenozoic. The first episode was characterized by NE-SW shortening that was initiated in the Late Jurassic–Late Cretaceous, and it may be related to the clockwise rotation of Yangtze Block and the far field effect of the Neo-Tethys ocean basin closed; and the second by NW-SE compressional shearing that was initiated in the Miocene–Pliocene and continues to the present day, and it is the result of the eastern extrusion of the Tibetan Plateau material. The magnetic fabrics associated with the weak deformation of the Ganluo Basin are mainly the result of layer-parallel shortening before folding, which is inferred to indicate Mesozoic NE-SW compression. In addition, the following atypical magnetic fabrics are present: (1) a magnetic foliation that is oblique to the bedding and associated with layerparallel simple shearing during folding, and (2) a magnetic lineation that is oblique to the strike of bedding to varying degrees, and that is the result of two superposed structures. The integrated study of field structures and magnetic fabrics indicates, therefore, that the N-S structures of the SYNSTB were mainly developed in the Mesozoic, but were subsequently overprinted by left-lateral strike-slip shearing during the Cenozoic. The resulting composite tectonic system provides further information on the tectonic evolution of the eastern margin of the Tibetan Plateau during the Mesozoic and Cenozoic.

Multi-regional Anti-jamming Communication Scheme Based on Transfer Learning and Q Learning

( Chen Han ),( Yingtao Niu ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.7

The smart jammer launches jamming attacks which degrade the transmission reliability. In this paper, smart jamming attacks based on the communication probability over different channels is considered, and an anti-jamming Q learning algorithm (AQLA) is developed to obtain anti-jamming knowledge for the local region. To accelerate the learning process across multiple regions, a multi-regional intelligent anti-jamming learning algorithm (MIALA) which utilizes transferred knowledge from neighboring regions is proposed. The MIALA algorithm is evaluated through simulations, and the results show that the it is capable of learning the jamming rules and effectively speed up the learning rate of the whole communication region when the jamming rules are similar in the neighboring regions.

Cutting performance of tool with continuous lubrication at tool-chip interface

Tongkun Cao,Yajun Liu,Yingtao Xu 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.7 No.2

To improve lubricating effect and reduce cutting fluid, a new lubricating method was proposed and a new cutting tool was fabricated. A micro-channel connected tool rake face with hydraulic pressure system was fabricated to continuously supply cutting fluid to tool-chip interface. Cutting tests on cast iron were carried out with the new cutting tool and conventional tools. Results show that the cutting forces, the friction coefficient at the tool–chip interface, chip size, the wear area and the adhesive effect of the new tool were significantly reduced compared with those of the conventional tool. EDS analysis results and SEM micrograph of worn surface verified that more cutting fluid can enter into the inner of interface between chip and tool through the micro-channel than flood lubricating. So more area can form liquid film that can reduce cutting force and friction and promote anti-wear. This is the main mechanisms responsible. Although adhesion is reduced, adhesive wear is the main wear mechanism for the new cutting tool as same as conventional tool.

A Fast Anti-jamming Decision Method Based on the Rule-Reduced Genetic Algorithm

( Jin Hui ),( Song Xiaoqin ),( Wang Miao ),( Niu Yingtao ),( Li Ke ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.9

To cope with the complex electromagnetic environment of wireless communication systems, anti-jamming decision methods are necessary to keep the reliability of communication. Basing on the rule-reduced genetic algorithm (RRGA), an anti-jamming decision method is proposed in this paper to adapt to the fast channel variations. Firstly, the reduced decision rules are obtained according to the rough set (RS) theory. Secondly, the randomly generated initial population of the genetic algorithm (GA) is screened and the individuals are preserved in accordance with the reduced decision rules. Finally, the initial population after screening is utilized in the genetic algorithm to optimize the communication parameters. In order to remove the dependency on the weights, this paper deploys an anti-jamming decision objective function, which aims at maximizing the normalized transmission rate under the constraints of minimizing the normalized transmitting power with the pre-defined bit error rate (BER). Simulations are carried out to verify the performance of both the traditional genetic algorithm and the adaptive genetic algorithm. Simulation results show that the convergence rates of the two algorithms increase significantly thanks to the initial population determined by the reduced-rules, without losing the accuracy of the decision-making. Meanwhile, the weight-independent objective function makes the algorithm more practical than the traditional methods.

Transient electrophoretic motion of a charged particle through a converging–diverging microchannel: Effect of direct current-dielectrophoretic force

Ai, Ye,Joo, Sang W.,Jiang, Yingtao,Xuan, Xiangchun,Qian, Shizhi WILEY-VCH Verlag 2009 Electrophoresis Vol.30 No.14

<P>Transient electrophoretic motion of a charged particle through a converging–diverging microchannel is studied by solving the coupled system of the Navier–Stokes equations for fluid flow and the Laplace equation for electrical field with an arbitrary Lagrangian–Eulerian finite-element method. A spatially non-uniform electric field is induced in the converging–diverging section, which gives rise to a direct current dielectrophoretic (DEP) force in addition to the electrostatic force acting on the charged particle. As a sequence, the symmetry of the particle velocity and trajectory with respect to the throat is broken. We demonstrate that the predicted particle trajectory shifts due to DEP show quantitative agreements with the existing experimental data. Although converging–diverging microchannels can be used for super fast electrophoresis due to the enhancement of the local electric field, it is shown that large particles may be blocked due to the induced DEP force, which thus must be taken into account in the study of electrophoresis in microfluidic devices where non-uniform electric fields are present.</P>

Expression of RUNX2/LAPTM5 in the Induction of MC3T3-e1 Mineralization and Its Possible Relationship with Autophagy

Xing Lei,Li Yanqin,Li Wenhao,Liu Rong,Geng Yuanming,Ma Weiqun,Qiao Yu,Li Jianwen,Lv Yingtao,Fang Ying,Xu Pingping 한국조직공학과 재생의학회 2022 조직공학과 재생의학 Vol.19 No.6

BACKGROUND: The study aims to correlate osteogenesis with autophagy during the mineralization induction of MC3T3-e1 through exploring the expression of runt-related transcription factor 2 (RUNX2)/lysosomal-associated transmembrane protein 5 (LAMPT5). METHODS: The induction of mineralization in MC3T3-e1 was followed by detecting the expressions of osteogenesisrelated indexes such as RUNX2, alkaline phosphatase (ALP), osteocalcin (OCN), and LAPTM5 using RT-qPCR and Western blot from 0 to 14 days. Transmission electron microscope was utilised in visualizing the alterations of autophagosomes, which was followed by immunofluorescence detecting the subcellular localization of autophagy-related index sequestosome 1 (P62) and microtubule-associated protein 1 light 3 (LC3) protein and scrutinising the expression of P62 mRNA and P62 and LC3 proteins. RESULTS: Induction of MC3T3-e1 mineralization demonstrated an increased expression of osteogenesis-related indicators such as RUNX2, ALP, OCN, and LAPTM5 (p\0.05), as evident from the results of RT-qPCR and Western blot. Meanwhile, the expression of autophagosomes increased one day after mineralization induction and then experienced a gradual decline, and enhanced expression of LC3 protein was noted on days 1–2 of mineralization induction but was then followed by a corresponding reduce. In contrast, a continuous increase was reported in the expression of P62 mRNA and protein, respectively (p\0.05). Up- and down-regulating RUNX2/LAPTM5 expression alone confirmed the aforementioned results. CONCLUSION: It was therefore proposed that RUNX2 may be responsible for an early increase and then a gradual decrease in LAPTM5-mediated autophagy through the regulation of its high expression. Meanwhile, increased LAPTM5 expression in osteogenic mineralization presumed that RUNX2/LAPTM5 promoted autophagy and osteogenic expression, which may play a bridging role in the regulation of autophagy and osteogenesis.

Resistive switching behavior and mechanism of room-temperaturefabricated flexible Al/TiS2-PVP/ITO/PET memory devices

Deyuan Lyu,Cong Hu,Yuting Jiang,Na Bai,Qi Wang,Deyan He,Jing Qi,Yingtao Li 한국물리학회 2019 Current Applied Physics Vol.19 No.4

The mixture of two-dimensional (2D) TiS2 nanoflakes and polyvinylpyrrolidone (PVP) exhibits a nonvolatile, bipolar resistive switching behavior with a low resistance state (LRS)/high resistance state (HRS) current ratio of ∼102 in the devices with a flexible Al/TiS2-PVP/indium tin oxide (ITO)/polyethylene terephthalate (PET) structure. The polymer-assistant liquid-phase exfoliation of 2D nanoflakes from TiS2 bulk material is processed in low-boiling solvent. And the fabrication process of these devices is performed entirely at room temperature. Such an energy-saving and scalable production process indicates a huge potential of large-scale industrial application. The AFM and TEM characterizations showed that the exfoliated 2D TiS2 are flakes at micrometer scale with a layer-number of mostly 7 or 8. Both the HRS and the LRS can be kept for more than 104 s. The endurance of devices was obtained over 100 direct current (DC) sweeping cycles with remarkable separations between different resistive states. The distributions of writing (set) and erasing (reset) voltages show that set and reset voltages are small (< 2 V). Also, the resistive switching characteristics of the devices are stable during 1000 bending cycles. The switching behavior is explained by the thinning and recovery of Schottky barriers within devices.
