| 1 | Fermentation characteristics and probiotic activity of a purified fraction of polysaccharides from Fuzhuan brick tea显示文摘Polysaccharides from Fuzhuan brick tea(FBTPS),one of most important bioactive components in tea,showed various health-promoting functions.Our previous work demonstrated that the crude FBTPS(CFBTPS)could modulate the gut microbiota.However,which purified fraction in CFBTPS contributing to the modulation of gut microbiota remains unclear.Thus,the fermentation characteristics and probiotic activity of a purified fraction(FBTPS-2-1)of CFBTPS were evaluated in this work.The results showed that gut microbiota could utilize FBTPS-2-1 to produce short-chain fatty acids including acetic,propionic,n-butyric and n-valeric acids.FBTPS-2-1 could modulate the structure and metabolic pathways of gut microbiota.FBTPS-2-1 could increase the health-promoting gut microbiota such as Prevotellaceae and Bifidobacteriaceae,and decreased the harmful bacteria such as Enterobacteriaceae and Fusobacteriaceae.The results of metagenomics showed that Prevotella copri and Megamonas funiformis were the dominant bacteria after fermentation of FBTPS-2-1.Furthermore,FBTPS-2-1 could regulate the biosynthesis and metabolism pathways of gut microbiota.Thus,the enrichment of food with FBTPS-2-1 is expected as a potential strategy for promoting human health due to modulation of gut microbiota. | Guijie Chen Ziqi Zeng Minhao Xie Yujia Peng Wangting Zhou Weiqi Xu Yi Sun Xiaoxiong Zeng Zhonghua Liu | 2022 | Food Science and Human Wellness2022，11，3： | 4 |
| 2 | Entropy correction of charged black hole via fermions tunneling beyond semi-classical approximation显示文摘Motivated by the idea of tunneling beyond semi-classical approximation of Majhi et al., we discuss entropy correction of Dirac particles tunneling from the Reissner-Nordstrm black hole with a global monopole. To get the corrections correctly, we regard the proportionality constants of quantum correction terms to the semi-classical term of action as the inverse of the square of the Planck Length but not that of the Planck Mass. Our study shows that corrections to the Bekenstein-Hawking entropy, namely the logarithmic term and the inverse area term, may be reproduced as the quantum effect is considered. | ZENG XiaoXiong 1 , LI Ling 2 & HU XinYun 3 1 Journal of Sichuan University of Arts and Science, Dazhou 635000, China 2 Department of Maths and Finance-Economics, Sichuan University of Arts and Science, Dazhou 635000, China 3 Library of Sichuan University of Arts and Science, Dazhou 635000, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 3 |

| 6 | Area spectra of BTZ black holes via periodicity显示文摘Motivated by the recent work that the periodicity of a black hole is responsible for the area spectrum,we exclusively utilize the period of motion of an outgoing wave,which is shown to be related to the vibrational frequency of the perturbed black hole,to study area spectra of a non-rotating BTZ black hole and a rotating BTZ black hole.It is found that the area spectra and entropy spectra for both space times are equally spaced.In addition,we find that though the entropy spectra of the 3-dimensional BTZ black holes take the same form as those of the 4-dimensional black holes,the area spectra depend on the dimension of space times.Our result confirms that the entropy spectrum of a black hole is more fundamental than the area spectrum. | LIU XianMing ZENG XiaoXiong ZHOU ShiWei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 1 |

| 8 | Phase transition and critical phenomenon of AdS black holes in Einstein-Gauss-Bonnet gravity显示文摘Thermodynamics of phase transition for a black hole in 5D Einstein-Gauss-Bonnet gravity with a negative cosmological constant is studied.As the Bekenstein-Hawking entropy is adopted,we find the heat capacity,volume expansion coefficient and isothermal compressibility are divergent at the critical points,which implies the existence of phase transitions.The fact that the phase transitions are indeed second order is revealed by studying the Ehrenfest's equations and the Prigogine-Defay ratio.Furthermore near the critical points,we also explicitly calculate the critical exponents of the relevant thermodynamic quantities at fixed charge or fixed temperature.It is shown that the corresponding critical exponents satisfy the thermodynamic scaling law.The Generalized Homogeneous Function hypothesis is also checked by studying the Helmholtz free energy,which is shown to be consistent with the thermodynamic scaling law. | HU Cheng ZENG XiaoXiong LIU XianMing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 1 |

| 12 | Spectroscopy of the rotating BTZ black hole via adiabatic invariance显示文摘According to Bohr-Sommerfeld quantization rule,an equally spaced horizon area spectrum of a static,spherically symmetric black hole was obtained under an adiabatic invariant action.This method can be extended to the rotating black holes.As an example,this method is applied to the rotating BTZ black hole and the quantized spectrum of the horizon area is obtained.It is shown that the area spectrum of the rotating BTZ black hole is also equally spaced and irrelevant to the rotating parameter,which is consistent with the Bekenstein conjecture.Specifically,the derivation does not need the quasinormal frequencies and the small angular momentum limit. | LIU XianMing ZENG XiaoXiong LIU WenBiao | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，10： | 1 |
