The aim of this study is to explore the correlations between fasciology and yin yang doctrine. Professor Yuan developed fasciology by three-dimensional reconstruction of connective tissue (fascia) in the trunk and limbs of the human body and tracing back to tissue origins in light of biological evolution and developmental biology. Fasciology states that the human body can be divided into two systems: the supporting-storing system and the functional system. This article elaborates on the roles of the two systems and their mutual relationship. The two systems are used to analyze the yin,the yang, and their relationship. The two systems are promoted but also restricted in different contexts. The supporting-storing system is formed by undifferentiated connective tissue and provides undifferentiated cells and nutrients for differentiated cells of the functional system. Thus, the supporting-storing system could be classified as quiet, similar to yin. The functional system continuously maintains the various functional activities of the human body. Thus, the functional system could be classified as active, similar to yang. In interpreting the yin yang doctrine from the point of view of fasciology, yin can be compared with the supporting-storing system and yang can be compared with the functional system.

Sin, Sang-Jin,Zhou, Yang IOP Publishing Ltd 2009 Journal of high energy physics Vol.2009 No.5

We propose a Dirac-Born-Infeld (DBI) D5 vertex brane plus <I>N</I><SUB><I>c</I></SUB> fundamental strings configuration to describe a baryon probe in strongly coupled gauge theory with gluon condensation at finite temperature via AdS/CFT correspondence. We investigate properties of this configuration in a dilaton deformed AdS<SUB>5</SUB> × S<SUP>5</SUP> background, in which IIB string theory is dual to super Yang-Mills theory in a state with a constant self-dual gauge field (<I>F</I><SUB><I>mn</I></SUB> = <I>F</I>*<SUB><I>mn</I></SUB>) background. We find that for most values of temperature <I>T</I> and gluon condensation parameter <I>q</I> (<I>q</I> = π<SUP>2</SUP>⟨<I>F</I><SUB><I>mn</I></SUB><I>F</I><SUB><I>mn</I></SUB>⟩), there always exists a screening length <I>L</I><SUB><I>s</I></SUB>. The relation <I>L</I><SUB><I>s</I></SUB> ∼ 1/<I>T</I> has been checked. We give the <I>q</I> dependence of <I>L</I><SUB><I>s</I></SUB>. We calculate the boost velocity <I>v</I>(<I>v</I> = −tanh η) and angular velocity ω dependence of <I>L</I><SUB><I>s</I></SUB> for a baryon probe, and obtain <I>L</I><SUB><I>s</I></SUB> = <I>L</I><SUB>0</SUB>*(1−<I>v</I><SUP>2</SUP>)<SUP>1/4</SUP> for large <I>v</I> and <I>L</I><SUB><I>s</I></SUB> ∼ ω<SUP>−1</SUP>, which are consistent with those dependence relations in the point brane plus strings case, and find that the usual relations have been modified by <I>q</I>. We also calculate the mass of baryon and find <I>T</I> dependence of baryon mass.

Zhou, Jianrong,Zhou, Xiaojuan,Zhou, Jianjin,Jiang, Xingfen,Yang, Jianqing,Zhu, Lin,Yang, Wenqin,Yang, Tao,Xu, Hong,Xia, Yuanguang,Yang, Gui-an,Xie, Yuguang,Huang, Chaoqiang,Hu, Bitao,Sun, Zhijia,Chen, Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.6

A novel ceramic Gas Electron Multiplier (GEM) has been developed to meet the demand of high counting rate for the neutron detection which is an alternative to ³He-based detector at China Spallation Neutron Source (CSNS). An experiment was performed to measure the neutron transmittance of ceramic-GEM and FR4-GEM at the small angle neutron scattering (SANS) instrument. The result showed the ceramic-GEM has higher transmittance and less self-scattering especially for cold neutrons. One single ceramic GEM could give a gain of 10²-10⁴ in the mixture gas of Ar and CO₂ (90%:10%) and its energy resolution was about 27.7% by using ⁵⁵Fe X ray of 5.9 keV. A prototype has been developed in order to investigate the performances of the ceramic GEM-based neutron detector. Several neutron beam tests, including detection efficiency, spatial resolution, two-dimensional imaging, and wavelength spectrum, were carried out at CSNS and China Mianyang Research Reactor (CMRR). The results show that the ceramic GEM-based neutron detector is a good candidate to measure the high intensity neutrons.

The Intrinsic Relation between the Hydrogel Structure and In Vivo Performance of Hyaluronic Acid Dermal Fillers: A Comparative Study of Four Typical Dermal Fillers

Zhou Weiwei,Hou Shuai,Deng Shu,Peng Yang,Fu Wei,Zhou Yang,Yang Jie,Peng Cheng 한국조직공학과 재생의학회 2023 조직공학과 재생의학 Vol.20 No.3

BACKGROUND: Hyaluronic acid dermal fillers are composed of cross-linked viscoelastic particles with high biocompatibility. The performance of the fillers is determined by the viscoelastic properties of particles and the connecting force between particles. However, the relationships among the properties of fillers, the interaction of the gels and the surrounding tissue are not clear enough. METHOD: Four kinds of typical dermal filler were selected in this research to reveal the interaction between the gels and cells. A series of analytical tools was applied to characterize the structure and physicochemical properties of the gel, as well as observing their interaction with the surrounding tissues in vivo and discussing their internal mechanism. RESULT: The large particles internal the gel and the high rheological properties endow the Restylane2 with excellent support. However, these large-size particles have a significant impact on the metabolism of the local tissue surrounding the gel. Juve´derm3 present gel integrity with the high cohesiveness and superior support. The rational matching of large and small particles provides the Juve´derm3 with supporting capacity and excellent biological performance. Ifresh is characterized by small-size particles, moderate cohesiveness, good integrity, lower viscoelasticity and the superior cellular activity located the surrounding tissues. Cryohyaluron has high cohesion and medium particle size and it is prominent in cell behaviors involving localized tissues. Specific macroporous structure in the gel may facilitate the nutrients delivering and removing the waste. CONCLUSION: It’s necessary to make the filler both sufficient support and biocompatibility through the rational matching of particle sizes and rheological properties. Gels with macroporous structured particle showed an advantage in this area by providing a space inside the particle.

A multi-objective optimization for HAWT blades design by considering structural strength

Yang Yang,Chun Li,Wanfu Zhang,Jun Yang,Zhou Ye,Weipao Miao,Kehua Ye 대한기계학회 2016 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.30 No.8

The challenge of wind turbine blade design is to balance the conflict between high capacity and heavy system loads introduced by the large scale rotor. To solve this problem, we present a multi-objective optimization method to maximize the Annual energy production (AEP) and minimize the blade mass. The well-known Blade element momentum (BEM) theory is employed to predict the aerodynamic performance and AEP of the blade. The blade is simplified as a thin Bernoulli beam. The cross section is modelled as a combination of composite layer, shear webs and spar caps typically. The strain of every cross section has been considered as a constraint to minimize the spar cap thickness for minimizing the blade mass. An improved genetic algorithm (NSGA-II) is applied to obtain the Pareto front set. Several solutions of the Pareto set are selected to compare with the reference blade (NREL 5MW blade). Performance of the rotors on design condition is simulated by STAR-CCM+ to verify the results of BEM theory. Optimal results show that the present blade, which is fully superior to the reference blade, can be selected from the Pareto set. The optimization design method can provide a superior blade with an increase by 2.48% of AEP and a reduction by 5.52% of the blade mass. It indicates the present optimization method is effective. Results of numerical simulations show that the spanwise flow would be increased obviously in tip region of the reference blade. The reason is that chord length variation in blade tip affects the flow and causes minor stall. The abrupt change of chord distribution in blade tip should be avoided to reduce the spanwise flow in initial blade design.

Effects of zearalenone on the localization and expression of the growth hormone receptor gene in the uteri of post-weaning piglets

Min Zhou,Li Jie Yang,Wei Ren Yang,Li Bo Huang,Xue Mei Zhou,Shu Zhen Jiang,Zai Bin Yang 아세아·태평양축산학회 2018 Animal Bioscience Vol.31 No.1

Objective: In this study, we investigated the adverse effects of dietary zearalenone (ZEA) (0.5 to 1.5 mg/kg diet) on the localization and expression of the growth hormone receptor (GHR) in the uteri of post-weaning gilts and explored alternative mechanism of the reproductive toxicity of ZEA on piglets. Methods: A total of forty healthy piglets (Duroc×Landrace×Large White) aged 28 d were selected for study. Piglets were transferred to single cages after 10 days’ adaptation on an obstetric table. The animals were allocated to one of four treatments: a normal basal diet supplemented with 0 (Control), 0.5 (ZEA0.5), 1.0 (ZEA1.0), or 1.5 (ZEA1.5) mg/kg purified ZEA, and fed for 35 d after the 10-d adaptation. Analyzed ZEA concentrations in the diets were 0, 0.52±0.07, 1.04±0.03, and 1.51±0.13 mg/kg, respectively. At the end of the feeding trial, piglets were euthanized after being fasted for 12 h. Two samples of uterine tissue from each pig were rapidly collected, one of which was stored at –80°C for analysis of the relative mRNA and protein expression of GHR, and the second was promptly fixed in Bouin’s solution for immunohistochemical analysis. Results: The relative weight of the uteri and thickness of the myometrium and endometrium increased linearly (p<0.001) and quadratically (p<0.001) with an increasing level of ZEA. The results of immunohistochemical analysis indicated that GHR immunoreactive substance was mainly localizated in the cytoplasm of uterine smooth muscle, glandular epithelial, luminal epithelial, stromal, and vascular endothelial cells. In contrast, nuclear staining was rarely observed. The immunoreactive integrated optic density of GHR in the myometrium, luminal epithelium, glandular epithelium, and whole uteri of weaning gilts increased linearly (p<0.001) and quadratically (p<0.05) with an increasing level of ZEA. The mRNA and protein expression of GHR in the uteri of weaning gilts increased linearly (p<0.001) and quadratically (p<0.05) with an increasing level of ZEA. Conclusion: In conclusion, ZEA at a concentration of 0.5 mg/kg was sufficient to significantly thicken the myometrium and endometrium, and at a concentration of 1.0 mg/kg induced a high level of GHR expression to promote growth and development of the uteri. This revealed an alternative molecular mechanism whereby ZEA induces growth and development of the uteri and provides a theoretical basis for the revision of Chinese feed hygiene standards.

Study on the neutron imaging detector with high spatial resolution at China spallation neutron source

Jiang, Xingfen,Xiu, Qinglei,Zhou, Jianrong,Yang, Jianqing,Tan, Jinhao,Yang, Wenqin,Zhang, Lianjun,Xia, Yuanguang,Zhou, Xiaojuan,Zhou, Jianjin,Zhu, Lin,Teng, Haiyun,Yang, Gui-an,Song, Yushou,Sun, Zhiji Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.6

Gadolinium oxysulfide (GOS) is regarded as a novel scintillator for the realization of ultra-high spatial resolution in neutron imaging. Monte Carlo simulations of GOS scintillator show that the capability of its spatial resolution is towards the micron level. Through the time-of-flight method, the light output of a GOS scintillator was measured to be 217 photons per captured neutron, ~100 times lower than that of a ZnS/LiF:Ag scintillator. A detector prototype has been developed to evaluate the imaging solution with the GOS scintillator by neutron beam tests. The measured spatial resolution is ~36 ㎛ (28 line pairs/mm) at the modulation transfer function (MTF) of 10%, mainly limited by the low experimental collimation ratio of the beamline. The weak light output of the GOS scintillator requires an enormous increase in the neutron flux to reduce the exposure time for practical applications.

Seismic Analysis for Nuclear Power Safety Related Bridge

Yang Zhou,Yi Sui,Xin Liu,Tao Gong 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.2

For the first time in China’s nuclear power industry, an in-plant emergency access bridge is proposed to be constructed. This bridge inside the nuclear power plants will serve as an important emergency evacuation route and as an access port for rescue operations in the power plant under potential accident conditions. Thus, the seismic safety of the bridge is a critical matter. This paper, which is based on a real engineering project, builds a refined finite element (FE) model for a continuous girder bridge-foundation structure. A seismic wave input method based on a nonlinear artificial boundary is used to suggest a reasonable size for a truncated foundation area for the purposes of dynamic simulations. The paper further discusses the influences of the nonlinear viscous artificial boundary and other various seismic wave input methods on the dynamic response of the bridge. Results show that compared to the traditional viscous artificial boundary, a nonlinear viscous artificial boundary has a better absorbing effect. The error of the bending moments at the bottom of piers improves from around 3.2% to around 1.9%. At the same time, compared to the “bottom wave + lateral free” and “bottom wave + lateral shear” of two seismic wave input methods, the nonlinear wave input method can generate results with higher accuracy. With the nonlinear input method, the error of the bending moment at the bottom of piers improves from around 13.7% to around 1.9%.

Crystal facet engineering induced anisotropic transport of charge carriers in a perovskite

Yang, Hewei,Zhou, Yunzhan,Yang, Yijun,Yi, Ding,Ye, Tao,Lam, Tran Dai,Golberg, Dmitri,Bao, Bate,Yao, Jiannian,Wang, Xi The Royal Society of Chemistry 2018 Journal of Materials Chemistry C Vol.6 No.43

<P>Precise control of crystal orientations and macroscopic morphology of a perovskite crystal is crucial for various optoelectronic applications relying on charge carrier transport tuning along exposed crystal facets. Here, taking methylammonium lead bromide (CH3NH3PbBr3) as an example, and employing a novel crystal facet engineering method, we successfully construct two kinds of perovskite crystals with exposed {001} and {110} facets. We find that the free carriers’ photoluminescence lifetime on the {001} facets can be 3 times longer than that on {110} facets. The related mechanisms are investigated <I>via</I> fluorescence lifetime imaging microscopy and <I>in situ</I> transmission electron microscopy. These indicate that the different trap state density of exposed facets and crystal structure changing of CH3NH3PbBr3 under light and electron beam irradiation lead to the differences in carrier transport along different facets. By distinguishing the charge carrier transport on different CH3NH3PbBr3 exposed facets, micro-photodetectors have been constructed. A device fabricated with the {001} exposed facets exhibited two orders of magnitude higher photocurrent and half as much dark current as a {110} facet-based device. Thus, the crystal facet engineering of perovskites can be widely adopted for understanding physical/chemical properties of perovskite crystals and provides great potential for novel perovskite optoelectronic device applications.</P>

Peroxiredoxin System of Aspergillus nidulans Resists Inactivation by High Concentration of Hydrogen Peroxide-Mediated Oxidative Stress

( Yang Xia ),( Haijun Yu ),( Zhemin Zhou ),( Naoki Takaya ),( Shengmin Zhou ),( Ping Wang ) 한국미생물생명공학회(구 한국산업미생물학회) 2018 Journal of microbiology and biotechnology Vol.28 No.1

Most eukaryotic peroxiredoxins (Prxs) are readily inactivated by a high concentration of hydrogen peroxide (H₂O₂) during catalysis owing to their “GGLG” and “YF” motifs. However, such oxidative stress sensitive motifs were not found in the previously identified filamentous fungal Prxs. Additionally, the information on filamentous fungal Prxs is limited and fragmentary. Herein, we cloned and gained insight into Aspergillus nidulans Prx (An.PrxA) in the aspects of protein properties, catalysis characteristics, and especially H₂O₂ tolerability. Our results indicated that An.PrxA belongs to the newly defined family of typical 2-Cys Prxs with a marked characteristic that the “resolving” cysteine (C_R) is invertedly located preceding the “peroxidatic” cysteine (C_P) in amino acid sequences. The inverted arrangement of C_R and C_P can only be found among some yeast, bacterial, and filamentous fungal deduced Prxs. The most surprising characteristic of An.PrxA is its extraordinary ability to resist inactivation by extremely high concentrations of H₂O₂, even that approaching 600 mM. By screening the H₂O₂-inactivation effects on the components of Prx systems, including Trx, Trx reductase (TrxR), and Prx, we ultimately determined that it is the robust filamentous fungal TrxR rather than Trx and Prx that is responsible for the extreme H₂O₂ tolerence of the An.PrxA system. This is the first investigation on the effect of the electron donor partner in the H₂O₂ tolerability of the Prx system.
