Sweet potato and potato residual flours as potential nutritional and healthy food material

引用

Journal of Integrative Agriculture 2017年第11期16卷 2632-2645页

作者： JU Dong mu Tai-hua SUN hong-nan Key Laboratory of Agro-Products Processing Ministry of Agriculture/Institute of Food Science and Technology Chinese Academyof Agricultural Sciences Beijing 100193 P.R.China

In this study, the proximate composition, mineral content and amino acid composition of starch processing residues from 10 cultivars of sweet potato and 10 cultivars of potato were determined, and the nutritional and health-related values of these residues were investigated. The residual flours contained 20.63-31.48 g and 17.14-28.57 g rich dietary fiber per 100 g dry weight for sweet potato and potato, respectively, as well as mineral elements, including potassium, ferrum, zinc and copper. The highest limiting amino acid score （AAS） of the almost balanced amino acid composition were observed to be 71.07 and 57.96 for sweet potato and potato residues, respectively. A grey relational analysis showed that the nutritional values of Jishu 4 at 0.7519 and LT-5 at 0.7281 were the highest among the sweet potato and potato residues, respectively. The evaluation of the sweet potato/potato residues, the by-products of the starch industry, based on recommended daily intake （RDI） standards, indicated that the residues have potential nutritional and health-related food values.

Brain＇s neural switch for social dominance in animals

Animals perform social behaviors during their lives to survive and reproduce. As one of the most robust and fundamental social behaviors, social dominance determines individual＇s behavioral displays, priority access to food, mate,territory or other resources, and impacts on its physical and mental health. In human society, socioeconomic status （SES）is a major predictor of physical and mental outcomes, even when the participants have equal access to health care. A Norwegian scientist Thorleif Schjelderup-Ebbe first scientifically described dominance behaviors when he observed

Computing top eigenpairs of Hermitizable matrix

Frontiers of Mathematics in China 2021年第2期16卷 345-379页

作者： mu-Fa CHEN Zhi-Gang JIA hong-Kui PANG Research Institute of Mathematical Science Jiangsu Normal UniversityXuzhou 221116China School of Mathematical Sciences Beijing Normal UniversityBeijing 100875China Laboratory of Mathematics and Complex Systems(Beijing Normal University) Ministry of EducationBeijing 100875China School of Mathematics and Statistics Jiangsu Normal UniversityXuzhou 221116China

The top eigenpairs at the title mean the maximal, the submaximal, or a few of the subsequent eigenpairs of an Hermitizable matrix. Restricting on top ones is to handle with the matrices having large scale, for which only little is known up to now. This is different from some mature algorithms, that are clearly limited only to medium-sized matrix for calculating full spectrum. It is hoped that a combination of this paper with the earlier works, to be seen soon, may provide some effective algorithms for computing the spectrum in practice, especially for matrix mechanics.

Urea L-malic acid, a new second order nonlinear optical crystal, was studied using density functional theory （DFT）. PBEPBE/6-31＋G（d,p） method, the optimal method for comparing the results from the several DFT methods, was chosen to study the molecular structure. Infrared and ultraviolet-visible spectra were obtained and compared with experiments. The ultraviolet-visible spectrum was also analyzed by the molecular orbital population. The geometries, and the infrared and ultraviolet-visible spectra in water were studied using DFT methods in combination with the polarized continuum model to predict the perturbations by the solvent effect.

Modeling and scenario prediction of a natural gas demand system based on a system dynamics method

引用

Petroleum Science 2018年第4期15卷 912-924页

作者： Xian-Zhong mu Guo-Hao Li Guang-Wen hu Institute of Recycling Economy Beijing University of Technology

Based on the study of the relationship between structure and feedback of China’s natural gas demand system, this paper establishes a system dynamics model. In order to simulate the total demand and consumption structure of natural gas in China, we set up seven scenarios by changing some of the parameters of the model. The results showed that the total demand of natural gas would increase steadily year by year and reach in the range from 3600 to 4500 billion cubic meters in 2035. Furthermore, in terms of consumption structure, urban gas consumption would still be the largest term, followed by the gas consumption as industrial fuel, gas power generation and natural gas chemical industry. In addition, compared with the population growth, economic development still plays a dominant role in the natural gas demand growth, the impact of urbanization on urban gas consumption is significant, and the promotion of natural gas utilization technology can effectively reduce the total consumption of natural gas.

Broadcast encryption schemes based on RSA

The Journal of China Universities of Posts and Telecommunications 2009年第1期16卷 69-75页

作者： mu Ning-bo hu Yu-pu OU Hai-wen The Ministry of Education Key Laboratory of Computer Networks and Information Security Xidian University Xi'an 710071 China Key Laboratory of Information Security and Secrecy Beijing Institute of Electronic Science and Technology Beijing 100070 China

Three broadcast schemes for small receiver set using the property of RSA modulus are presented. They can solve the problem of data redundancy when the size of receiver set is small. In the proposed schemes, the center uses one key to encrypt the message and can revoke authorization conveniently. Every authorized user only needs to store one decryption key of a constant size. Among these three schemes, the first one has indistinguishability against adaptive chosen ciphertext attack （IND-CCA2） secure, and any collusion of authorized users cannot produce a new decryption key but the sizes of encryption modulus and ciphertext are linear in the number of receivers. In the second scheme, the size of ciphertext is half of the first one and any two authorized users can produce a new decryption key, but the center can identify them using the traitor tracing algorithm. The third one is the most efficient but the center cannot identify the traitors exactly.
