File surveys focus on diversity of arboreal bat within Nanling National Nature Reserve from 2010 to 2016. A high species diversity of arboreal bats in the region is revealed (8 genera and 13 species). Murina harrisoni is a new chiropteran record in Guangdong province, China, and Myotis muricola is the new finding in the Nanling Nature Reserve, Guangdong. Among 13 arboreal species, 4 and 3 species belong to Murina and Myotis respectively. Furthermore, there are 1 Arielulus species, 1 Pipistrellus species, 1 Hypsugo species, 1 Harpiocephalus species, 1 Tylonycteris species, and 1 Scotomanes species that are recorded in this region. From conservation status perspective, M. ruforniger and A. circumdatus are in Vulnerable (VU), while 5 species including M. chinensis are classified as Near Threatened (NT). 4 species including P. pipistrellus are Least Concern (LC), while M. harrisoni and M. shuipuensis are listed as Data Deficient (DD).

In order to understand the status quo of Mastacembelus armatus resources in South China, by tracking their measurable characters and frame structure, we analysed the relationship between body weight and morphological traits, and the morphological differences in groups of 171 fishes from seven M. armatus wild populations. Path analysis showed that the total length had largest direct effect on their body weight, body thickness was the second, but head depth had negative effect. The result of principal component analysis showed that main morphological differences concentrate on trunk and head which were closely associated with feeding. The result of cluster analysis revealed that seven populations were clustered into three clades, the first group included Longyan, Lechang, Wuhua, Baise and Enping populations, Honghe and Baisha populations were formed two independent clusters respectively. The discriminant rate could reach more than 95%, which established a discriminant formula on the three branch of M. armatus: the Pearl River and Hanjiang Riverdepartment, Red River department, and Nandu River department. All above indicated that morphological differentiation existed among the seven populations of M. armatus.

In August 2015, through harp traps forest-habitated bat was collected from Yanlin county, Hunan province. Three specimens are medium-sized with distinct tubed nostrils and thick red-brown pelages; the hind legs, wing membrane and uropatagium membrane are covered with fine hair. The forearm ranges from 47.8 mm to 52.2 mm, while the greatest skull length is 20.66~22.21 mm. Although our sampling is limited, the males are smaller than the female, which is consistent with pervious conclusion of sexual dimorphism. They were identified as Harpiocephalus harpia, a new chiropteran record in Hunan province, China. Meanwhile, MaxEnt ecological model was used to predict the potential distribution of H. harpia within China. Our results indicate that low temperature is a key limiting factor that influences its distribution and coastal area of South China is its main distribution area. Furthermore, the predicted distribution within Hainan province needs to be further verified in future.

Odd gracefulness and odd strongly harmoniousness of dumbbell-shape graphs C_n+C_m+P_l have been studied. We have obtained that dumbbell-shape graphs C_n+C_m+P_l are odd graceful graph when n=4k,m=4t and n=4k+2,m=4t+2, and that dumbbell-shape graphs C_n+C_m+P_l are odd strongly harmonious graph when n=4k,m=4t.

This paper proposes a new design, the Cox uniform design of mixture experiment, by using the Cox method to transform the D-optimal design points in the simplex to uniform design points and determine the most uniform design by calculating the MSE deviation. We have proved that the Cox uniform design can maintain the D- optimality in the transformed region. The model established by this method is closer to the real model and more robust.

This paper deals with a novel three order nonlinear partial differential equation, the Derrida-Lebowitz-Speer-Spohn equation, which describes the statistical properties of the fluctuations along with an achored interface at a sufficiently low noise level in two-dimensional Toom model. Firstly, a nonlinear transformation of the Derrida-Lebowitz-Speer-Spohn equation is obtained and the Derrida-Lebowitz-Speer-Spohn equation is reduced to a corresponding linear partial differential equation by using this nonlinear transformation. Then many explicit exact solutions for the reduced linear partial differential equation are obtained by applying the method of variable separation. With the aid of the nonlinear transformation given here, abundant explicit exact solutions to the Derrida-Lebowitz-Speer-Spohn equation are obtained in the end.

Our observations were carried out in December 2012, through 13.7 m millimeter telescope of the Purple Mountain Observatory (PMO) at Qinghai Delingha. Observation data including the J=1-0 lines of ¹²CO and its isotopomers toward one sample of molecular clouds with different Galacocentric distance are analyzed. Through fitting of their spectra lines, we got the integrated intensity ratio of ¹²CO and ¹³CO transition lines for our sample. Our results for our molecular clouds show, this ratio, which reflects the isotope ratio ¹²C/¹³C, range from 2 to 6 or so. These are much lower than those of the local ISM and the solar system. And there is no trend of increasing ratio along with the increase of the Galacocentric distance, which is predicted by the inside-out formation scenario of our Galaxy. This hints that our results were affected much by the optical depth effect toward our molecular clouds. Coming observations on selected optical thin molecular lines toward our sample will be better, and other subordinate effects on the ratio results from the integrated line intensities are also needed to be considered, in order to determine accurately the isotope ratio ¹²C/¹³C and further to check the possible trend, i.e., increasing ratio along with increase of the Galacocentric distance.

The Arabidopsis IQM2, coded by AT3G13600, is a calmodulin-binding protein (CaMBP) containing an IQ motif. The leaves of the IQM2 mutant iqm2-2 and its corresponding wild type Landsberg erecta (Ler) show the similar lesions after being infected by Pst DC3000. Photosynthesis is essential for plant growth and development as well as responding to the environmental cue. Fluorescence parameter is an important indicator to judge photosynthesis. Thus, the fluorescence parameters are measured in iqm2-2 and Ler during infection of Pst DC3000. The resluts show that the quantum yield of Ler and iqm2-2 were significantly decreased after being treated with Pst DC3000. And the decline rate quantum yield of Ler is more significant than iqm2-2. The photochemical quenching value and the electron transport rate also decrease to some extent. However, the maximum quantum yield keeps stable. It can be postulated that IQM2 is involved in the process of plant reaction to disease. However, the mechanism remains to be studied.

In the process of soft soil seepage, the viscosity and shear performance of bound water have a great hindering effect. The soft soil circle hole microstructure seepage model considers the effects of the viscosity and shear performance of bound water, the surface electric potential of soil particles, the conductivity, the concentration and electric field of ions. The calculation results and the experimental results have a goodness of fit. The theory of circle hole seepage has great significance in the soft soil seepage engineering.

A kind of cement-based fire-proof coating is presented in this paper. This coating is made of aerogel waste powder from the production of aerogel plates. The relationship between the fireproof performance of the coating and the dosage of aerogel powder is investigated. The results show that the cement-based aerogel coating has good fireproof performance. The conductivity coefficient of the coating decreases with the increase of aerogel dosage. The conductivity coefficient of the fireproof coating decreases from 0.227 W·m^-1·K^-1 to 0.084 W·m^-1·K^-1 with the decrease of the dry bulk density from 813 kg·m^-3 to 527 kg·m^-3. The fire-proof performance of the coating is strengthened and then weakened with the increase of the aerogel dosage. The fire-proof limit time of the coating increases from 41 minutes to 70 minutes with the decrease of the dry bulk density from 813 kg·m^-3 to 583 kg·m^-3. The fireproof limit time decreases to 50 minutes with the decrease of the dry bulk density to 527 kg·m^-3.

For the removal of 2,4-dinitroaniline (DNAN) from environmental water, the magnetic molecular imprinted polymers (MMIPs), which had specific recognition and easy regeneration properties, were prepared by combining molecular imprinting technology and magnetic separation technology in this study. The obtained MMIPs were characterized by scanning electron microscopy (SEM) and the adsorption experiments for the study of the morphology and the recognition mechanism. Results showed that the MMIPs with Divinylbenzene (DVB) as crosslinking agent had high adsorption capacity to DNAN. The Scatchard analysis showed that there existed two kinds of binding sites between DVB-MMIPs, the template-High affinity site and low affinity site. The apparent maximum number (Q_max) of the MMIPs were 6.98×10^-6 mol·g^-1 and 5.71×10^-4 mol·g^-1 respectively, and the dissociation constant (K_{D) were 4.68×10^-6 mol·L^-1 and 1.40×10^-3 mol·L^-1 respectively for high affinity site and low affinity site. In comparison with the magnetic non- imprinted polymers (MNIPs), MMIPs showed higher adsorption capacity and selectivity to the template molecule, DNAN. Furthermore, the MMIPs have also been used successively to get rid of the DNAN from the environmental water samples with satisfactory recovery, overcoming the disadvantages of traditional adsorption materials with low selectivity and difficulties to recycle.}

Current literature of group-buying pricing basically considers a single merchant, and usually ignores the influence of the advertising effect on pricing decision. This paper studies the pricing decision for duopoly group-buying merchants with a fixed pricing mechanism. First, we obtain the optimal store prices of both merchants. And then both merchants conduct the group-buying business. Considering the advertising effect of the group-buying, the optimal group-buying prices of both merchants are obtained, and generate Nash equilibrium. We prove the optimal group-buying prices of both merchants are increasing functions of the customer transfer ratio, and decreasing functions of advertising effect factor. The optimal group-buying price is also a function of the commission ratio charged by the group buying website, however, the monotonicity of the function depends on the advertising effect factor. At last, an example shows the optimal store prices, the optimal group-buying prices and the profits for the duopoly, and the conclusion follows that adopting group-buying business can increase demand and profit for the merchants, and can bring lower price for the customers, and realize a mutual benefit for both the merchants and the customers.
