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 This paper propose an in-depth study on gan (甘) and tian (甜) by investigating a number of historical documents of various registers from the Pre-Qin to the Ming and Qing dynasties.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.
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.
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.

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.

<P><B>Abstract</B></P> <P>Highly transparent Nd-doped yttria ceramics were fabricated by hot-pressing at 1600 °C with single addition and co-addition of ZrO<SUB>2</SUB> and La<SUB>2</SUB>O<SUB>3</SUB>. The binary additives were found to promote the densification of yttria more effectively than single addition, resulting in higher transmittance.

The optical absorption, luminescence, and fluorescence decay of this sample was investigated. The absorption cross-sections of the sample at 806 nm and 820 nm were 1.22 × 10<SUP>−20</SUP> and 1.31 × 10<SUP>−20</SUP> cm<SUP>2</SUP>, respectively. The strongest emission was measured at 1078 nm with a full-width at half-maximum of 5 nm with excitation at 808 nm and a fluorescence lifetime of 423 μs. Additionally, the microhardness of the all samples is ranging from 7.88 to 7.05 GPa with variation of the grain size from 0.85 to 1.81 μm, while the fracture toughness of the all samples is about 1 MPa m<SUP>1/2</SUP> and was found to be almost unchanged.

Background: The current standard treatment for patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) is rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP). A significant number of patients were not treated with recommended dose of rituximab due to limited financial resources in Malaysia. This study evaluates the efficacy of R-CHOP like chemotherapy in Malaysian patients with DLBCL. Materials and Methods: The study comprised a retrospective analysis of patients with DLBCL treated at a single centre. The outcome was compared with patients who were treated with R-CHOP like and CHOP like chemotherapy. Patients who were treated with lower dose of rituximab was subanalysed for outcome. Results: A total of 86 patients who had CHOP-like chemotherapy were included. Only 39 (45%) patients had rituximab and only 12 (29%) patients had the recommended dose. The overall response (OR) and complete response (CR) rates were 88% and 81% respectively. There was no significant difference in OR and CR in patients who had rituximab and those without rituxmab. Those with International Prognostic Index (IPI) score of ${\leq}2$ had significant higher CR rate, progression free survival (PFS) and overall survival (p<0.001). Conclusions: The lack of significant improvement in CR and DFS in our patients may be due to an inadequate dose of rituximab.
