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 This paper propose an in-depth study on gan (甘) and tian (甜) by investigating a number of historical documents of various registers from the Pre-Qin to the Ming and Qing dynasties.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

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.

This paper analyzes the nodes deployment optimization problem in energy constrained wireless sensor networks, which multi-hop cooperative beamforming (CB) based cooperative-multi-input-single-output (CMISO) transmission is adopted to reduce the energy consumption. Firstly, we establish the energy consumption models for multi-hop SISO, multi-hop DSTBC based CMISO, multi-hop CB based CMISO transmissions under random nodes deployment. Then, we minimize the energy consumption by searching the optimal nodes deployment for the three transmissions. Furthermore, numerical results present the optimal nodes deployment parameters for the three transmissions. Energy consumption of the three transmissions are compared under optimal nodes deployment, which shows that CB based CMISO transmission consumes less energy than SISO and DSTBC based CMISO transmissions. Meanwhile, under optimal nodes deployment, the superiorities of CB based CMISO transmission over SISO and DSTBC based CMISO transmissions can be more obvious when path-loss-factor becomes low.

<P><B>Abstract</B></P> <P>In this work, highly transparent yttria ceramics Φ = 55 mm in size were fabricated by a hot-pressing method with 1 at.% ZrO<SUB>2</SUB> or 12 at.% La<SUB>2</SUB>O<SUB>3</SUB> as a sintering additive. For a 4-mm-thick specimen doped with ZrO<SUB>2</SUB>, the in-line transmittance reaches 71.1% at 400 nm and 80.9% at 1100 nm, and the transmittance of the La<SUB>2</SUB>O<SUB>3</SUB>-doped specimen is comparable to that of the ZrO<SUB>2</SUB>-doped specimen. By means of the relatively low sintering temperature of 1600 °C, the present samples exhibited very fine microstructures (<2 μm), giving rise to excellent mechanical strength levels (∼200 MPa). With regard to the 1 at.% ZrO<SUB>2</SUB>-doped specimen, the combination of high strength and high thermal conductivity (∼10 W/m K) substantially improved parameters related to the thermal shock resistance. The results of this study indicate that the hot-pressed transparent yttria ceramic doped with 1 at.% ZrO<SUB>2</SUB> is optically, mechanically, and thermally suitable for high-temperature IR window applications.</P>

As it is known, the researches on ownership transfer issues of RFID tag have focused on a single owner. However in practice, RFID tag may have multiple owners who occupy different weights. To solve the problem, the ownership transfer protocol of multi-owner with different weights based on Lagrange has been proposed. Assuming the key is divided into n parts in this paper, and the owner gets the corresponding sub secret key according to the weight. Then, If and only if the sum of the weights of the owners involved in the restoration of the secret key is equal to or greater than t, the secret key can be obtained, or not. Therefore, security of ownership transition and flexibility in the practical application are enhanced.

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.

Lecitase Ultra and 6 triacylglycerol lipases (lipases PS, M, AH, AY, R, and AK) were immobilized on Amberlite XAD 7HP and used to catalyze the acidolysis reaction between lecithin and capric acid (C10:0) for comparison. The highest molar incorporation value (51.0 mol%) was observed for the immobilized Lecitase Ultra. Further, immobilized Lecitase Ultra was selected for catalyzing acidolysis between lecithin and fatty acids with different chain lengths (C6:0, C8:0, C10:0, C12:0, and C14:0). After reaction, free fatty acids were removed by SPE and the resultant was called modified lecithin fraction 1 (MLF1). The highest molar incorporation value was obtained for C10:0 (51.0 mol%) at 45 A degrees C with a mole ratio of 10/1 (C10:0/lecithin) for 72 h. After removal of lysophosphatidylcholine by solid-phase extraction from MLF1, the resultant modified lecithin fraction 2 (MLF2) was used to prepare an oil-in-water emulsion. All emulsions prepared with MLF2 exhibited significantly higher emulsion stability (ES) values (16.2-17.7) and smaller particle sizes (d (32) 0.40-0.49 mu m, d (43) 0.75-1.01 mu m) than the emulsion prepared with unmodified lecithin (ES 14.1, d (32) 0.76 mu m, d (43), 1.26 mu m) (P < 0.05). Furthermore, less clarification and droplet aggregation were observed in emulsions prepared with MLF2 than in lecithin-based emulsions. Overall, the MLF2s showed better emulsifying properties than lecithin.

The NLRC4 inflammasome, a member of the nucleotide-binding and oligomerization domain-like receptor (NLR) family, amplifies inflammation by facilitating the processing of caspase-1, interleukin (IL)–1β, and IL-18. We explored whether NLRC4 knockdown alleviated inflammatory injury following intracerebral hemorrhage (ICH). Furthermore, we investigated whether NLRC4 inflammasome activation can be adjusted by the regulator of G protein signaling 2/leucine-rich repeat kinase-2 pathway. Fifty microliters of arterial blood was drawn and injected into the basal ganglion to simulate the ICH model. NLRC4 small interfering RNAs (siRNAs) were utilized to knockdown NLRC4. An LRRK2 inhibitor (GNE7915) was injected into the abdominal cavity. Short hairpin (sh) RNA lentiviruses and lentiviruses containing RGS2 were designed and applied to knockdown and promote RGS2 expression. Neurological functions, brain edema, Western blot, enzyme-linked immunosorbent, hematoxylin and eosin staining, Nissl staining, immunoprecipitation, immunofluorescence assay and Evans blue dye extravasation and autofluorescence assay were evaluated. It was shown that the NLRC4 inflammasome was activated following ICH injury. NLRC4 knockdown extenuated neuronal death, damage to the blood-brain barrier, brain edema and neurological deficiency 3 days after ICH. NLRC4 knockdown reduced myeloperoxidase (MPO) cells as well as tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and IL-18 following ICH. GNE7915 reduced pNLRC4 and NLRC4 inflammasome activation. RGS2 suppressed the interaction of LRRK2 and NLRC4 and NLRC4 inflammasome activation by regulating pLRRK2. Our study demonstrated that the NLRC4 inflammasome may aggravate the inflammatory injury induced by ICH and that RGS2/LRRK2 may relieve inflammatory injury by restraining NLRC4 inflammasome activation.
