Tingting Tang(Tingting Tang),Somkiat Mansumitrchai(Somkiat Mansumitrchai ) KINFORMS 2022 Management Review Vol.17 No.2

The main focus of this paper is to determine the antecedents which significantly affect the attitude toward digital wallet adoption in the context of Chinese youth and to explore the moderating role of demographic and behavioral factors on the relationships between digital wallet adoption and its antecedents. The sample consists of 212 respondents. The multiple regression results indicated that perceived complexity and trialability have statistically significant relationships with digital wallet adoption. Moreover, the moderated regression analysis showed that the frequency of usage significantly moderates the relationship between the intention to adopt digital wallets and relative advantages. The findings of this study not only improve understanding of predictors affecting digital wallet adoption and behavioral differences influencing the degree of adoption but also provide insights for digital wallet service providers to redesign and develop their program to increase customer satisfaction rate.

Tingting Xu,Xiaoya Chen,Xiuming Cui,Chengxiao Wang,Lisha Qiu 한국원예학회 2023 원예과학기술지 Vol.41 No.4

Maca, Lepidium meyenii Walpers (Brassicaceae), has been the subject of much research due to its unique biological activity. Maca is widely distributed in Yunnan Province, China, but is not well recognized in the market. In this study, through a chemical analysis, high-performance liquid chromatography (HPLC), and principal component analysis (PCA), the nutritional and bioactive components of different varieties, processing methods, harvesting times, and storage periods of maca were determined and analyzed. The results indicated that whole maca when dried at 35°C, harvested around the winter solstice and planted at an altitude of about 3,000 meters was favorable for the production of nutrients and bioactive components. Compared to black maca, yellow maca had higher levels of glucosinolates, flavonoids, alkaloids and macamides. In addition, a shorter storage period (less than one year) of maca leads to a higher content of bioactive components. The findings here provide a scientific basis for the cultivation and origin processing of maca

Mathematical framework for a new micro-electrical impedance tomography system

Tingting Zhang,EunJung Lee,Jin Keun Seo,Eung Je Woo 한국산업응용수학회 2010 한국산업응용수학회 학술대회 논문집 Vol.5 No.2

This work presents a mathematical framework of a new microscopic electrical impedance tomography (micro-EIT) system which aims to pro￢duce cross-sectional conductivity images of a biological tissue sample or cells inside a small hexahedral container. Unlike conventional micro-EIT systems which have much in common with a standard EIT system, the proposed micro-EIT system has a unique electrode configuration and associated data collection method. Two sides of the container facing each other are fully covered by driving electrodes. Injecting current between this driving electrode pair, we can create a uniform parallel current density distribution inside the container when it is filled with a homogeneous saline. We install many miniature electrodes on the other two sides and the bottom of the container for voltage measurements. The top of the container is open for sample manipulations. This electrode configuration provides a large number of voltage measurements from the three surfaces subject to one current injection. In this paper, we provides a mathematical framework of this novel micro-EIT system for the development of image re-construction algorithms. Taking advantage of the uniform parallel current density, we construct an inversion formula of the conductivity from the acquired boundary voltage. Employing the reciprocity theorem for the electrode configuration, we compute a sensitivity matrix to reconstruct cross-sectional conductivity images. Numerical simulations show that the proposed algorithm successfully reconstructs conductivity images of multiple anomalies. In terms of the image quality, the new micro-EIT system is advantageous over a conventional EIT method adopting multiple current injection patterns. For experimental studies to be followed, we suggest micro-EIT system developments based on the proposed novel idea.

Energy-Saving for a Velocity Control System of a Pipe Isolation Tool Based on a Reinforcement Learning Method

Tingting Wu,Hong Zhao,Boxuan Gao,Fanbo Meng 한국정밀공학회 2022 International Journal of Precision Engineering and Vol.9 No.1

The pipe isolation tool (PIT) demonstrates remarkable advantages in safety and efficiency compared with traditional plugging devices. However, its utilization in plugging operations is limited by the operation duration. In addition, the existing energy recovery system has low energy saving efficiency. In this paper, a real-time control energy-saving system of the PIT was designed based on a reinforcement learning algorithm. First, an experimental device for energy-saving was designed. Secondly, the energy distribution scheme of a hydraulic pump and accumulator based on experimental data was proposed. Finally, the reinforcement learning algorithm was used to adjust the opening of the hydraulic pump and the accumulator valves in real time during the plugging process to improving energy saving efficiency. The results verify that the energy saving efficiency of the PIT control system based on reinforcement learning could reach 23.71%, which satisfies the objectives of energy-saving and environmental applicability.

Tingting Xie,Hongtao Hu,Donghui Chen,Pengzhe Sun 대한화학회 2017 Bulletin of the Korean Chemical Society Vol.38 No.7

(B4C/C)-β-PbO2 electrodes were prepared by high-pressure molding technique and characterized by X-ray diffraction, scanning electron microscopy, polarization curves, cyclic voltammetry curves, and corrosion resistance test. In this paper, the effects of initial concentration, current density, electrolyte concentration, pH, and electrode spacing on tetracycline hydrochloride (TCH) degradation were investigated. Results indicated that modified electrode had high electrochemical activities, high oxygen evolution potential, and excellent corrosion resistance. The maximum removal rate of TCH could reach 90.87% at initial concentration of 300 mg/L after 120 min electrolysis with Na2SO4 concentration of 0.2 mol/L, electrode spacing of 1 cm, current density of 30 mA/cm2, and pH 3. Pseudo-first-order kinetics equation was followed during electrocatalytic degradation of TCH with 20%(B4C/C)-β-PbO2 electrode.

est19 is a gene from Bacillus sp. K91 that encodes a new esterase. A comparison of the amino acid sequence showed that Est19 has typical Ser-Gly-Asn-His (SGNH) family motifs and could be grouped into the SGNH hydrolase family. The Est19 protein was functionally cloned, and expressed and purified from Escherichia coli BL21(DE3). The enzyme activity was optimal at 60°C and pH 9.0, and displayed esterase activity towards esters with short-chain acyl esters (C2-C6). A structural model of Est19 was constructed using phospholipase A1 from Streptomyces albidoflavus NA297 as a template. The structure showed an α/β-hydrolase fold and indicated the presence of the typical catalytic triad Ser49-Asp227-His230, which were further investigated by site-directed mutagenesis. To the best of our knowledge, Est19 is a new member of the SGNH hydrolase family identified from thermophiles, which may be applicable in the industrial production of semisynthetic β-lactam antibiotics after modification.

Tingting Gao,Songli Mei,Hua Cao,Leilei Liang,Chengchao Zhou,Xiangfei Meng 대한신경정신의학회 2022 PSYCHIATRY INVESTIGATION Vol.19 No.12

Objective The present study aimed to examine the mediated moderation effect underlying the association between parental psychological aggression and phubbing, as well as the mediating role of anxiety and moderating role of sex and grade. Methods Based on a cross-sectional study, a total of 758 Chinese junior high school students had completed measures on socio-demographic characteristics, parental psychological aggression, anxiety and phubbing. Structural equation modeling was adopted to examine the mediating effect of anxiety on the association between parental psychological aggression and phubbing. Multigroup analyses were conducted to explore whether the path coefficients differed by sex and grade. Results Mediation analysis indicated that anxiety could mediate the association between parental psychological aggression and phubbing. The indirect effect of parental psychological aggression on phubbing via anxiety was 0.12. Multigroup analyses revealed that the higher mediation effect of anxiety was more likely to be reported by boys and students from grade eight. Conclusion Findings of the present study may inform prevention and intervention programs for phubbing in adolescents exposed to parental psychological aggression, by decreasing the anxiety and adopting selective strategies for different sex and grade groups.
