On the Syntactic Status of Cognate Objects
Yu Long 한국중원언어학회 2020 언어학연구 Vol.0 No.54
The syntactic status of cognate objects (COs) has attracted a lot of attention among researchers in the literature. As a first approximation, Jones (1988) and Moltmann (1989) advocate the adjunct analysis of COs, in which COs are regarded as an adjunct. On the contrary, Massam (1990) and Macfarland (1995) support the argument analysis of COs, in which COs are considered as an argument. At last, Kim & Lim (2012) favor the mixture of COs" properties. That is to say, COs exhibit both adjunct and argument properties in their analysis. In fact, both the adjunct and argument analysis are judged to be flawed because they restrict COs" properties to only one category. In addition, although the last analysis captures both the adjunct and argument characteristics of COs, it is still defective in that it fails to consider the vital role of COs" modification. Accordingly, I put forward my own proposal with the aim of capturing the exact status of COs. Specifically, I delve into COs" status on the basis of my distinction between the Cos with unaccusatives and those with unergatives.
Effect of branched alumina on thermal conductivity of epoxy resin
Yu Long,Lirui Shi,Qingyu Wang,Haitao Qu,Chuncheng Hao,Qingquan Lei 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.120 No.-
Composites prepared by using epoxy resin (EP) as matrix had limited practical applications owing to theirpoor thermal conductivity. The thermal conductivity of composites can be enhanced by doping inorganicfillers. However, it could not be significantly enhanced owing to the saturation of inorganic fillers. In thisstudy, we prepared branched alumina (b-Al2O3) by using high-temperature sintering and doped it as afiller to obtain b-Al2O3/EP composites. The results shown that the thermal conductivity of the EP compositeswith 70 wt% b-Al2O3 was 1.13 Wm1K1, which was seven times higher than that of pure EP. Thiscould be attributed to the overlapping of b-Al2O3 for the formation of a continuous mesh structure thatresults in thermal conduction channels inside the EP, which reduced the interfacial thermal resistanceand improved the thermal conductivity of the composite. The resistivity of b-Al2O3/EP was 9.64 1014Xm and that of pure EP was 2.08 1014 Xm. The dielectric constant of the b-Al2O3/EP compositesincreased with the increase in b-Al2O3 content, while the dielectric loss factor decreases. This was significantfor the application of EP composites in the field of electrical insulation.

−It is imperative to have an in-depth understanding of the intrinsic reaction between coal and oxygen during low-temperature oxidation, as the reaction is the main source responsible for the self-heating and spontaneous combustion of coal. As low-temperature oxidation of coal involves a series of physical and chemical process and many parallel reactions, it is difficult to directly investigate the intrinsic reaction between coal and oxygen by conventional analytical method. Thermogravimetric analysis (TGA) was used to investigate the intrinsic reaction between coal and oxygen based on the mass change. By means of the subtraction analysis method of TGA, the TG-subtraction curves were obtained by subtracting the TG-N2 curves from the TG-air curves. The results indicate that a TG-subtraction curve can better reflect the intrinsic reaction of coal oxidation than a TG-air curve by eliminating the influence of evaporation of water and thermal decomposition of inherent oxygen-containing groups. In terms of the rate of mass increase, the intrinsic reactions can be divided into three stages: slow oxidation stage, advanced oxidation stage and rapid oxidation stage. The activation energy at each of the stages, obtained by Coats and Redfern’s model, can be used to as a technical parameter to evaluate the proneness of coal spontaneous combustion. The optimum experiment conditions were also developed to study low-temperature coal oxidation with the subtraction method of TGA.

Yulong Zhao,Xiaobo Li,Jing Liang,Zhuangde Jiang 대한기계학회 2013 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.27 No.3
High-g accelerometers are widely used in explosion and shock measurement. This paper describes a MEMS piezoresistive high-g accelerometer whose range is more than 50000g. It is designed on the basis of silicon on insulator (SOI) solid piezoresistive chip. The chip has a structure where both ends of the beam are fixed. Through the stress analysis and mode analysis of the accelerometer, the detailed parameters of the structure are established. The experimental results obtained from the drop hammer shock machine test and live-fire test show good properties of the accelerometer such as good output characteristic, repeatability and fast response speed. Therefore, the accelerometer in this paper meets the requirement of explosion and shock measurement basically.

In this paper, an event driven backstepping positioning controller based on the structural reliability is developed for a turret-moored floating production storage and offloading (FPSO) vessel with unknown slow timevarying disturbances. The mathematical model of the FPSO vessel is given at first. Secondly, to make full use of the positioning capability of mooring system while ensuring the safety of mooring lines, a continuous backstepping positioning controller is designed based on the structural reliability of the mooring system; in the meanwhile, a disturbance observer is designed to handle the unknown disturbances. Then, the proposed event driven positioning controller is achieved based on the designed continuous controller by designing suitable event driven conditions, which can determine the updated time instants of the event driven positioning controller. The proposed positioning controller can not only guarantee the uniform ultimate boundness of the errors for structural reliability and heading but also ensure that no Zeno behavior occurs. Finally, the simulations demonstrate that the proposed event driven positioning controller’s performance while reducing the execution times of FPSO vessel’s actuators.

Previous research in the academic field of intangible cultural heritage has mainly focused on qualitative research from the macro-perspective, and quantitative methodology has seldom been used to explore the relationship between the research trajectory and resulting literature from the micro-perspective. Based on the Web of Science database and CiteSpace bibliometric analysis software, this paper analyses 1,097 papers on intangible cultural heritage produced between 2003 and 2019 from the co-citation network (author, research institution and journal), the scientific field, and the dominant or hot topics , and reveals the evolution and distribution of publications in the field of intangible cultural heritage across the globe. This paper describes global trends in academic research on intangible cultural heritage, leading to the shared innovation of cross-cultural horizontal communication and the sustainable exploration of vertical inheritance.

Catabolite control protein A (CcpA) is the major transcriptional regulator in carbon catabolite repression in several Gram-positive bacteria. We attempted to characterize the role of a CcpA homologue of Streptococcus suis type 2 in sugar metabolism and virulence. Addition of glucose or sucrose to the defined medium significantly reduced the activity of raffinose-inducible α-galactosidase, cellobiose-inducible β-glucosidase, and maltose-inducible α-glucosidase of the wildtype strain by about 9, 4, and 2-3 fold, respectively. Deletion of ccpA substantially derepressed the effects of repressing sugars on α-galactosidase or β-glucosidase activity. The ccpA deletion mutant showed reduced expression of virulence genes sly and eno (P<0.05), decreased adhesion to and invasion into endothelial cells (P<0.05), and attenuated virulence to mice with significant reduction of death rate and bacterial burden in organs, as compared to the wild-type strain. Both the in vitro and in vivo defect phenotypes were reversible by ccpA complementation. Thus, this study shows that CcpA of S. suis type 2 plays an important role in carbon catabolite repression and virulence.
