In this proceeding, I review the attempts to calculate the Nucleon resonance （including Roper as first radially excited state of nucleon and other excited states） using lattice quantum chromodynamics （QCD）. The latest preliminary results from Hadron Spectrum Collaboration （HSC） with mπ≈ 380 MeV are reported. The Sachs electric form factor of the proton and neutron and their transition with the Roper at large Q2 are also updated in this work.

Southern root-knot nematode （Meloidogyne incognita） is a major problem in vegetable production in China due to the expansion of plastic tunnel and solar greenhouse. Using resistant cultivars is an effective approach to control the disease. Nine genes, Mi-1 to Mi-9, have been reported and only Mi-1 has been successfully used in tomato breeding. However, Mi-1 is inactive at a temperature above 28~C. In order to identify sources for heat-stable resistance to southern root-knot nematode, 53 genotypes of tomato （Solarium spp.） were inoculated with an isolate of M. incognita in the growth chamber at 28 or 32℃ for initial screening. 28 lines had less than 25 galls and were considered as resistant candidates. The top 60% （16 in total） of resistant candidates obtained from each temperature were subject to re-evaluation at 32~C using the same nematode isolate. Three lines ZN17, ZN 48, and LA0385 showed heat-stable resistance with an average of 10 galls or less per plant. LA0385 is a wild species, while ZNI7 and ZN48 are elite breeding lines. These lines were grown in a greenhouse for two seasons, and also showed high resistance with less than 10 galls per plant. Thus they were considered as good sources for breeding resistance to southern root-knot nematode in tomato.

For a graph G and two positive integers j and k, an m-L（j, k）-edge-labeling of G is an assignment on the edges to the set {0, 1, 2,..., m}, such that adjacent edges which receive labels differ at least by j, and edges which are distance two apart receive labels differ at least by k. The λj,k-number of G is the minimum m such that an m-L（j, k）-edge-labeling is admitted by G. In this article, the L（1, 2）-edge-labeling for the hexagonal lattice, the square lattice and the triangular lattice are studied, and the bounds for λj,k-numbers of these graphs are obtained.

Rice ratooning cultivation is an imperative breakthrough technology for promoting supply-side structural reform of agriculture, implementing the national plan to reduce the area of double-cropping rice in the Yangtze River basin, China. While, at the same time, it also contributes to ensure the absolute safety of grain ration and optimize grain production structure in China. Rice ratooning is a cropping system in which we take advantage of the regeneration characteristics of the rice plant. For instance, the axillary buds grow rapidly into seedlings and then proceed to the stage of tillering, heading, grain filling and ripening through adopting different planting measures after the main crop (the first cropping rice) is harvested. Ratoon rice has a long history dating back 1 700 years in China. Presently, two models are commonly employed for harvesting of ratoon rice, which are manual harvesting and mechanized harvesting of ratoon rice. However, with the migration of Chinese rural labor forces, mechanized technology for ratoon rice has now become the main planting and harvesting mode. Moreover, this is also the recommended cultivation technique with promising high grain yields and better economic efficiency and more importantly it has become increasingly popular due to its beneficial aspects with the ongoing efforts of scientific research. The grain yield for both the main crop and ratooning crop is usually 15 t ha^–1 yr^–1 with a significant improvement on the economic benefits compared to the middle season and double season rice, respectively.

In the determination of the Earth gravity field in satellite geodesy, the inclination functions represent the projection of data observed along the orbital plane of a satellite orbit into the sphere in the terrestial reference frame. The inclination functions in this work is studied from a group theoretical perspective. The inclination functions are proved to generate a representation of the SO(3) group. An orthogonal relation of the inclination functions is derived and some recurrence relations for the inclination functions are given, based on which an algorithm to calculate the inclination functions is proposed.

AIM: To evaluate the efficacy and safety of Traditional Chinese Medicine (TCM) in the treatment of Helicobacter pylori (H pylori) infection. METHODS: We electronically and manually searched electronic databases, references lists and conferences compilations, and included all randomized clinical trials comparing the treatment of H pylori using TCM with proton pump inhibitor or colloidal bismuth subcitratebased triple therapy as controls. The Jadad score was used to assess trial quality, H pylori eradication rate and the incidence of side effects were taken as outcome measurements, and heterogeneity analysis, meta-analysis and funnel plot analysis were conducted. RESULTS: Sixteen trials were included. The Jadad scores of all the trials were not more than 2. Clinical heterogeneity and substantial statistical heterogeneity existed among the trials (P = 0.001, I 2 = 59%) and meta-analysis was not conducted. The average eradication rates following TCM and triple therapy were 72% and 78% and the incidence of side effects were 2% and 29%, respectively. The funnel plot was obviously asymmetric. CONCLUSION: Available evidence is not convincing enough to show that TCM has the same efficacy as triple therapy in H pylori treatment. TCM may be safer than triple therapy. TCM should not be recommended as monotherapy in H pylori infection.
