A new water-soluble polysaccharide (PSP) was isolated from the waste of a Sisal (Agave sisalana) plant after the plant's fibers were extracted. The monosaccharide composition analysis showed that PSP consists of galactose, glucose, mannose, rhamnose, arabinose, and galacturonic acid in a molar ratio of 3.0:2.4:1.4:1.0:0.2:0.2. The structure analysis indicated that the PSP backbone chain comprises 1,4-linked β-D-Gal. p; 1,3-linked β-D-Glc. p; 1,3-linked α-D-Man. p; and 1,2-linked α-L-Rha. p in a ratio of 3:1:1:1. Some of the Glc. p, Man. p, and Rha. p residues in the backbone chain were branched. The invitro antioxidant activity assay showed that PSP moderately scavenges hydroxyl and DPPH radicals in a dose-dependent manner. © 2013 Elsevier Ltd.

Nonlinear Analysis: Real World Applications | Year: 2012

In this paper, a class of stochastic functional differential equations given by dx(t)=(Ax(t)+F(t,x(t), xt))dt+G(t,x(t), xt) °dω(t),t∈[0,T],x(t)=φ(t)fort∈[-σ,0], is investigated. Under some suitable assumptions, the existence and stability of quadratic-mean almost periodic mild solutions for the equations are discussed by means of semigroups of operators and fixed point method. Moreover, an example is given to illustrate our results. © 2011 Elsevier Ltd. All rights reserved.

A cave-dwelling loach, Oreonectes luochengensis sp. nov. has been described based on collections from a cave in Tianhe town, Luocheng, Guangxi, China in September 2008. It can be distinguished from all known Oreonectes species by the following combination of characters: dorsal-fin rays 3, 7; anal-fin rays 2, 5; pectoral-fin rays 1, 11-12; pelvic-fin rays 1, 7 and 14-16 branched caudal-fin rays; head compressed; eyes present; surface of lower lip covered with shallow longitudinal groove; dorsal-fin origin posterior to vertical line of pelvic-fin origin; caudal peduncle without caudal-adipose keels; edge of caudal fin truncation; tiny scales present under skin; no cephalic lateral-line system; body pink in living status, without pigments in adult, after fixed in formalin, body yellowish, non-transparent, no markings on body side.

A new blind loach of the genus Triplophysa was collected in 2007 from a cave in Leyi village, located near Chuanshan Town, Huangjiang County in the Guangxi Zhuang Autonomous Region of southern China. The new species, Triplophysa huangjiangensis sp. nov, can be distinguished from its congeners by eyes and scales absent; caudal-fin forked; adipose keel present; lips with furrows; distal margin of dorsal-fin truncate, dorsal fin origin much closer to caudal-fin base than snout tip; 8-9 branched dorsal-fin rays; 6-7 branched pelvic-fin rays; 6 branched anal-fin rays; 10-11 branched pectoral-fin rays; 13-14 branched caudal-fin rays; pectoral-fin length 52.3%-70.7% the distance between pectoral-fin origin to pelvic-fin origin; dorsal-fin origin posterior to vertical line of pelvic-fin origin; outer rostral barbel longer than other two pairs of barbels, with 47.0%-73.8% of lateral head length; anterior nostril with elongate barbel-like tip; and posterior chamber of gas-bladder developed, reaching pelvic-fin origin.

According to extensive quantity of public and factual data, this essay does tests on BIAS and W&R expert system of stock-market trading software in simulation experiment method, and compares their strength and weakness in the respect of mathematical statistics theory and Management objects, winning rate, annual return rate and net profit rate. The tests show that BIAS expert system is 2.58 times as good as W&R expert system in the items of annual return rate and net profit rate, 0.26 times in the item of the total number of trading. As a whole, BIAS expert system is superior to W&R expert system. © (2013) Trans Tech Publications, Switzerland.

Using the method of statistical experiment and based on real and open data of securities, the research conducted a test to the W&R and RSI expert system of securities trading software. Taking annual net profit margin, rate of return, and win rate as the management objectives, the research compared and analyzed the two similar reversal trend indicators on the basis of mathematic statistics theories, and achieved results that the annual rate of return and net profit margin of the RSI expert system are superior to that of the W&R expert system for 4.72 times, and that the annual number of trades of RSI is superior to that of W&R for 0.893 times. © (2013) Trans Tech Publications, Switzerland.

Based on the public and actual massive data of securities market, through testing the MA and RSI expert system of securities trading software by simulation experiment method, with the winning percentage, the annual rate of return, and the net profit margin as the management objectives, and with the theory of mathematical statistics as the research basis, the article carried out the comparative analysis of strength and weakness of these two systems. Except the annual transaction number, RSI expert system is comprehensively superior to MA expert system. © (2013) Trans Tech Publications, Switzerland.

It established the indexes, criteria and system dynamics model of evaluating water resources carrying capacity. Assessment for water resources carrying capacity was carried out for the implementation of the eleventh five-year overall planning outline for the development of national economy and society in Wuhan (draft). The result showed that the supply and demand of water resources could maintain balance under four scenarios by 2010. But the use of cross-border water resources need be increased to achieve the sustainability of the use of water resources. © 2011 Springer-Verlag.

This paper presents tests security transaction BOLL expert systems, through statistical experiments, with the wining rate, annual rate of return and net profit rate as the management objectives, on basis of the mass data generated by the security market; The results show that win rate value of BOLL expert system as high as 88.95%, and annual rate of return and net profit rate are 33.37% and 13.9% respectively. Compared with RSI expert system, the transaction times are only 52.09% of RSI expert system, which should be the true reason why the rate of turn of BOLL expert system is not high. © (2014) Trans Tech Publications, Switzerland.

In this thesis, Some adaptive neural control design ways are presented for a class of multi-input multi-output (MIMO) nonlinear systems in block-triangular form with disturbance input and state time-varying delay. Neural networks are employed to approximate the unknown continuous functions. By combining the use of a novel quadratic-type Lyapunov-Krasovskii functionals and adaptive NN backstepping, an adaptive neural controller is obtained, which efficiently avoids the controller singularity. The proposed control guarantees that all closed-loop signals remain bounded, while the output tracking error dynamics converges to a neighborhood of the desired trajectories. The feasibility is investigated by a simulation example. © 2012 ICIC International.
