This study aimed to identify and analyze the characteristics of highly cited biomass articles in the Science Citation Index Expanded that were published between 1900 and 2013. Articles with at least 100 citations from the Web of Science Core Collection were selected, and the following characteristics were recorded: publication year, authors, institutions, countries/territories, journals, Web of Science categories, and citation life cycles. The results show that 3407 highly cited articles were published between 1966 and 2011, and the most highly cited biomass articles were published in Ecology. The USA produced 49% of all highly cited articles and contributed the most single, internationally collaborative, first-author, single-author, and corresponding-author articles. All of the top 13 most productive institutions were located in the USA. In addition, the Y-index was successfully applied to evaluate the publication characteristics of authors. Authors publication intensities for highly cited articles in biomass research and their publication characteristics were analyzed. © 2015 Elsevier Ltd.

Structure and properties of complexes (energies and charge transfer) of complexes BrF-HX (X = F, Cl, Br, I) have been investigated at the MP2/aug-cc-pVDZ (aug-cc-pVDZ-pp basis sets for I) level. Two types of geometries (hydrogen-bonded and halogen-bonded) are observed. The calculated interaction energies show that the halogen bonded structures are more stable than the corresponding hydrogen-bonded structures. To study the nature of the intermolecular interactions, symmetry-adapted perturbation theory (SAPT) energy decomposition analysis reveals that the BrF-HX complexes are dominantly electrostatic in nature. © 2011 Wiley Periodicals, Inc.

The key problem in analyzing dynamic interaction between saturated soils and structure by indirect boundary element method is to obtain dynamic Green's function of a stratum. In recent years, many scholars devoted to exploring a variety of solutions to dynamic Green function in different stratums, and made some important achievements. However, most isotropic saturated soil models were utilized to simulate the saturated ground because of the complexity of mechanical model of media, and little attention had been paid for the transversely isotropic saturated soil ground model, which may be more reasonable for the saturated soil derived from natural marine deposit or lake deposit. The author have systematically explored the 3-D non-axisymmetric Lamb's problem in transversely isotropic saturated media and analyzed the effects of the anisotropic parameters of media on its dynamic response of the displacement, stress and pore fluid pressure, respectively. The objective of this paper is to study dynamic green function for internal barrel loads in transversely isotropic saturated soils. Based on Biot's 3-D wave theory for fluid-saturated porous media, the nonsymmetrical general solutions for wave equations of transversely isotropic saturated soils in cylindrical coordinate are presented by the Fourier expanding and Hankel integral transform method as well as operator theory. Then, using general solutions, a layered saturated stiffness matrix and a saturated half-space stiffness matrix are derived exactly. Furthermore, the dynamic Green's functions for internal barrel distributed vertical load and horizontal loads in layered transversely isotropic saturated soils are presented, respectively, thus a key problem to analyze dynamical interaction between saturated soils and piles in boundary element method is solved.

The objective of the study was to investigate the antioxidant effect of Chinese medicine Coriolus versicolor polysaccharide on brain tissue and its mechanism in rats. SOD, MDA and GSH-Px levels in rat brain tissues were determined with SD rats as the animal model. The results showed that Coriolus versicolor polysaccharide can reduce the lipid peroxidation level in brain tissues during exhaustive exercise in rats, and can accelerate the removal of free radicals. The study concluded that its antioxidant effect is relatively apparent.

This paper proposes an adaptive neural network control method for a class of perturbed strict-feedback nonlinear systems with unknown time delays. Radial basis function neural networks are used to approximate unknown intermediate control signals. By constructing appropriate Lyapunov-Krasovskii functionals, the unknown time delay terms have been compensated. Dynamic surface control technique is used to overcome the problem of "explosion of complexity" in backstepping design procedure. In addition, the semiglobal uniform ultimate boundedness of all the signals in the closed-loop system is proved. A main advantage of the proposed controller is that both problems of "curse of dimensionality" and "explosion of complexity" are avoided simultaneously. Finally, simulation results are presented to demonstrate the effectiveness of the approach. © 2012 Institute of Automation, Chinese Academy of Sciences and Springer-Verlag Berlin Heidelberg.
