It is important to study the diachronic change and replacement of old words by new ones in Chinese etymology as the process does not happen and complete within a short span of time. This paper propose an in-depth study on gan (甘) and tian (甜) by investigating a number of historical documents of various registers from the Pre-Qin to the Ming and Qing dynasties. Based on the diachronic perspective, we conduct a quantitative analysis to show the lexical development and replacement process of gan (甘) and tian (甜) in its original and extended meanings. In the meantime, we also describes usage pattern and competition process of the two words in different periods, by comparing them in terms of usage frequency, semantic expression and syntactic distribution. Because gan (甘) is a polysemy with multiple meanings since the Pre-Qin dynasty, a new word tian (甜) with a single meaning of sweet taste emerged in the Western Han dynasty, which is subsequently commonly used in oral literature in the Wei and Jin dynasties. Afterwards, tian (甜) went into competition with gan (甘) in the Tang and Song dynasties, whose meaning was in turn further extended to psychological and sensory domains in the Ming and Qing dynasties. In modern Chinese, gan (甘) came to only function as a morpheme through semantic bleaching whereas tian (甜) often appeared in sentential structure. The semantic and syntactic functions of the two words remain stable and still in use.
Low Resistance and Transparent Ag/AZO Ohmic Contact to p-GaN

Silver (Ag)/ aluminum-doped zinc oxide (AZO) films were deposited on p-GaN by using electronbeamevaporation. After the annealing process, current -voltage (I-V) measurements were carriedout to determine the characteristic of the contacts. The Ag/AZO films annealed at 600 C werefound to present an ohmic contact behavior. The specific contact resistance was calculated tobe 9.76 × 10−4cm2 and the transmittance was over 80% for visibly light. The atomic forcemicroscope was used to measure the aggregation of Ag grains which may have been the main factorin the formation of the Ag/AZO ohmic contact to p-GaN.

Power converter plays a very important role in switched reluctance motor (SRM) systems, and it is also the easiest one to experience failures. Power converter faults will cause the motor to run in non equilibrium states, and a long time fault operation will lead to motor and other modules damaged, and make the system completely lose working stability. This paper uses an asymmetric bridge converter as the research object with three-phase SRM, employs the wavelet packet decomposition for the phase currents. It analyzes and studies the short circuit fault condition of IGBT, uses an energy discrete degree of the wavelet packet nodes as the fault characteristic, and conducts the corresponding experimental and simulation analysis to verify the effectiveness and practicality of the proposed method.

Clonostachys rosea (syn. Gliocladium roseum) is a well-known biocontrol agent and widely distributed around the world. In this study, an endochitinase gene Crchi1 was isolated from the mycoparasitic fungus C. rosea using the DNA walking strategy. The Crchi1 ORF is 1,746 bp long and interrupted by three introns. The cloned gene Crchi1 encodes 426 amino acid residues and shares a high degree of similarity with other chitinases from entomopathogenic and mycoparasitic fungi. Several putative binding sites for transcriptional regulation of Crchi1 in response to carbon (5'-SYGGRG-3') and nitrogen (5'-GATA-3') were identified in the upstream of Crchi1. Expression of Crchi1 gene in different carbon sources was analyzed using real-time PCR (RT-PCR). We found that the Crchi1 expression was suppressed by glucose but strongly stimulated by chitin or solubilized components of the cell wall from Rhizoctonia solani. Phylogenetic analysis of chitinases from entomopathogenic and mycoparasitic fungi suggests that these chitinases have probably evolved from a common ancestor.
Embracing Domesticity Between the Wars : The Writing of Jan Struther
Gan, Wendy 한국영미문학페미니즘학회 2001 영미문학페미니즘 Vol.8 No.2
This paper examines a little-known British writer named Jan Struther in an effort to shed light on domestic ideologies between the wars. Struther's middlebrow writing, forgotten today but a success in its time, is important in revealing how domesticity can be re-packaged for the modern interwar woman. In a period where feminist progress in terms of partial franchise and increasing work opportunities for women jostled with reactionary ideologies that positioned women in the home once again, I argue that Struther's work in her comic essays and her bestselling Mrs. Miniver highlights the struggle of middle-class women to confront domestic limitations, not by resisting and rejecting domesticity, but by updating domesticity itself.
Cluster Lifetime Analysis for Cooperative Beamforming in Wireless Sensor Networks
Gan Xiong,Lu Hong,Yang Guangyou 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.10
Cooperative multiple input multiple outputs (MIMO) or its variation cooperative multiple input single outputs (MISO) is becoming a potential technique to minimize the energy consumption and prolong lifetime in wireless sensor networks. For cluster based wireless sensor networks, cluster lifetime for cooperative beamforming (CBF) based cooperative MISO scheme is studied in this paper.We first establish the energy model of a cluster with cooperative MISO scheme based on CBF. Based on the energy consumption model, the effects of cluster size and distance between cluster and sink node on the performance of cluster lifetime are discussed, an joint optimization to maximize cluster lifetime by finding the optimal modulation parameter and number of cooperative nodes is proposed. Numerical results show that CBF based cooperative MISO scheme can achieve longer cluster lifetime compare with STBC and the joint optimization can further improve the cluster lifetime.

Coronavirus disease 2019 poses an occupational health risk to health-care workers. Several thousand health-care workers have already been infected, mainly in China. Preventing intra-hospital transmission of the communicable disease is therefore a priority. Based on the Systems Engineering Initiative for Patient Safety model, the strategies and measures to protect health-care workers in an acute tertiary hospital are described along the domains of work task, technologies and tools, work environmental factors, and organizational conditions. The principle of zero occupational infection remains an achievable goal that all health-care systems need to strive for in the face of a potential pandemic.
SPIRAL WAVE GENERATION IN A DIFFUSIVE PREDATOR-PREY MODEL WITH TWO TIME DELAYS
GAN, WENZHEN,ZHU, PENG Korean Mathematical Society 2015 대한수학회보 Vol.52 No.4
This paper is concerned with the pattern formation of a diffusive predator-prey model with two time delays. Based upon an analysis of Hopf bifurcation, we demonstrate that time delays can induce spatial patterns under some conditions. Moreover, by use of a series of numerical simulations, we show that the type of spatial patterns is the spiral wave. Finally, we demonstrate that the spiral wave is asymptotically stable.
Geopolitics and Regionalism : China`s New Silk Road: Where Does It Lead?
( Gan Jun Xian ),( Mao Yan ) 경남대학교 극동문제연구소 2016 ASIAN PERSPECTIVE Vol.40 No.1
We analyze the driving forces behind China’s New Silk Road (NSR) initiative and find that they not only included short-term factors, such as the US “rebalance” of forces in Asia and China’s economic slowdown since 2012, but also long-term factors such as China’s ambition to recover its past glory and integrate itself still further into the global economy. We then look at the external challenges facing China’s initiative, such as geopolitical competition, fear of overdependence, and political instabilities along the old silk routes. We highlight China’s policy dilemmas and discuss the sustainability of China’s NSR initiative and its implications for the world. Our conclusion is that China’s initiative could be in for a rocky road, but if it strikes a good balance between its diplomatic objectives and means and its values and actions, the NSR could speed up regional integration. KEYWORDS: China, the New Silk Road, geopolitical conflicts, regional integration.
