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.

RLDB: Robust Local Difference Binary Descriptor with Integrated Learning-based Optimization

( Huitao Sun ),( Muguo Li ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.9

Local binary descriptors are well-suited for many real-time and/or large-scale computer vision applications, while their low computational complexity is usually accompanied by the limitation of performance. In this paper, we propose a new optimization framework, RLDB (Robust-LDB), to improve a typical region-based binary descriptor LDB (local difference binary) and maintain its computational simplicity. RLDB extends the multi-feature strategy of LDB and applies a more complete region-comparing configuration. A cascade bit selection method is utilized to select the more representative patterns from massive comparison pairs and an online learning strategy further optimizes descriptor for each specific patch separately. They both incorporate LDP (linear discriminant projections) principle to jointly guarantee the robustness and distinctiveness of the features from various scales. Experimental results demonstrate that this integrated learning framework significantly enhances LDB. The improved descriptor achieves a performance comparable to floating-point descriptors on many benchmarks and retains a high computing speed similar to most binary descriptors, which better satisfies the demands of applications.

MODEL-BASED CONTROL OF ELECTROMAGNETIC VALVE ACTUATORS FOR ENGINE SPEED CONTROL

Huitao Chen,Siqin Chang,Aimin Fan 한국자동차공학회 2019 International journal of automotive technology Vol.20 No.1

The introduction of electromagnetic valve actuators (EMVA) benefits engine fuel economy, torque performance and reduction of emissions. Meanwhile, it complicates the controller for the purpose of regulating the additional freedom degrees of intake valvetrain, such as valve lift, opening timing and opening duration. In order to address the control issue of EMVA application, a model-based controller is needed to realize that the cylinder air charge is regulated by controlling the EMVA motion directly for controlling the engine speed and output torque. For the development of the controller, a control-oriented model of engine with EMVA that can simulate the intake process of unthrottled operation, torque generation and crankshaft rotational dynamics was first developed. Then a model-based EMVA controller was designed to regulate the actuation of electromagnetic intake valves which consisted of a feedforward and a PID feedback module. According to torque-based concept, engine speed reference was translated into torque demand using optimal control theory and the speed control problem was solved as two parts: torque management that decided torque demand and the torque demand tracking. The simulations carried out in Matlab/Simulink verified the effectiveness of the controller. In addition, a test platform of the EMVA for hardware-in-the-loop (HIL) simulation was established and the practicability of EMVA application to engine intake systems was validated preliminarily.

Probabilistic design optimization of wind turbine gear transmission system based on dynamic reliability

Chen Huitao,Fan Junkai,Jing Shuangxi,Wang Xianhui 대한기계학회 2019 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.33 No.2

In this paper, a probabilistic design optimization method for wind power gear drive system has been put forward based on the dynamic reliability. A pure torsional dynamic model of 1.5 MW wind turbine gear transmission system is developed which is based on lumped parameter method with incorporation of gear meshing stiffness and transmission error. By taking the wind load and the gear parameters as random variables, the variation in dynamic reliability of the system with time is obtained. The probabilistic optimization design model of the wind turbine gear transmission system with minimum displacement and volume is built. The parameters affecting the dynamic performance and reliability are taken as optimization design variables. The system reliability, the effects of random parameters on the reliability, the normal meshing condition and gear strength are taken as constraint conditions. We choose the gear transmission system of a 1.5 MW wind turbine for the system optimization and experimental verification. The results show that the system optimization based on dynamic reliability can reduce the volume of the system by 17.94 % and the system reliability is also guaranteed. Moreover, the vibration of each component of the system is reduced which is beneficial for smooth operation of the gear transmission system of wind turbine.

Herpesvirus infections in Cervidae are a serious threat affecting some deer species worldwide. In our attempt to identify malignant catarrhal fever-associated herpesviruses in deer herds, ten gammaherpesviral DNA fragments were identified in five species of deer in herds in China by using a pan-herpesvirus polymerase chain reaction assay targeting viral DNA polymerase. Notably, in sambar (Rusa unicolor), a novel gamma-2 herpesvirus was identified that showed a close relationship with fallow deer lymphotropic herpesvirus (LHV), while the other fragments were phylogenetically grouped together with Elk-LHV. Determination of whether these viruses have any clinical implication in these deer species should be undertaken urgently.

Cold tolerance is the primary limiting factor affecting the quality and productivity of chrysanthemum (Dendranthema morifolium). However, few studies have investigated the molecular mechanisms underlying the low temperature response in chrysanthemum. In the present study, we used RNA-Seq technology to compare the transcript profiles of chrysanthemum leaves exposed to two different temperatures (20 and −8 °C). A total of 13.54 Gb of clean reads were assembled into 71,971 unigenes with an average length of 694 bp, and 33,282 unigenes were annotated identified from five well-known protein databases. Of these, 9579, 24,252, 7123, 22,554, and 32,891 unigenes were separately identified in the COG, GO, KEGG, Swiss-Prot, and NCBI databases, respectively. Differentially expressed genes (1592 upregulated and 718 downregulated) were identified between the control (CK) and low temperature treatment (T) groups. KEGG pathway enrichment analysis identified 20 significantly different pathways. Many genes encoding important transcription factors (e.g. CBF/DREB, bHLH, MYC, and ZAT) as well as proteins (e.g. CCX, CBP, CML, and MAPK) involved in cold signal transduction were up- or down-regulated in the low temperature treatment group. Genes involved in ABA signal transduction and biosynthesis of unsaturated fatty acids were also identified. The expression profiles of these genes were analyzed during the cold treatment stage. These results provide important information for further studies on gene discovery in chrysanthemum and suggest a potential molecular mechanism for the response to low temperature in this plant species.

A high-resolution timescale for the Miocene Shanwang diatomaceous shale lagerstätte (China): development of Wavelet Scale Series Analysis for cyclostratigraphy

Jifeng Yu,Xinlong Pang,Wenzhao Fu,Jason Hilton,Mingmei Liang,Zongkai Jiang,Xiuli Zhao,Wenyan Qiao,Suo Shi,Diandong Zhang,Huitao Cao,Haibo Jia,Yadong Wang,Xiaoke Hu,Rui Zhang 한국지질과학협의회 2021 Geosciences Journal Vol.25 No.5

The Miocene aged Shanwang Formation from the Shanwang National Geopark in China represents a succession of lacustrine diatomaceous shales containing an abundant and diverse biota with lagerstätte fossilization of soft tissues. To date, the Shanwang Formation has not been investigated for cyclostratigraphy nor has it been dated with high precision methods. Now we use thorium data as a paleoenvironmental and paleoclimatic proxy to conduct a detailed cyclostratigraphic analysis. A new and simple cyclostratigraphic method, Wavelet Scale Series Analysis (WSSA) is developed to recognize Milankovitch cycles. A total of three short eccentricity and fifteen precession cycles are identified; obliquity cycles are not apparent. In the sedimentary succession, the corresponding precession and short eccentricity cycles are 1.17 m and 4.98 m thick respectively, with this verified by Correlation Coefficient (COCO) analysis and Multitaper-Method (MTM) spectral analysis. We estimate the studied interval was deposited over a duration of 0.3 Myr with a depositional rate of c. 5.7 cm/kyr. Paleomagnetic and radio isotope dating data shows that the diatomaceous shale was deposited during Chron C5En, which places it at approximately 18.5 Ma during the Burdigalian stage of the Early Miocene, rather than in the Middle Miocene as previously thought. The Shanwang lagerstätte biota therefore predates the Middle Miocene Climate Optimum (MMCO) and did not form within it. The geological time scale with a high resolution of 20 kyr was set accordingly.
