Decoding an Old 1907 Prescription of Dr.Ing Hay(“Doc Hay”):One of the Earliest Chinese Medicine Doctors in the United States

Objectives:Chinese medicine doctors have practiced in the United States since April of 1854,the world's first Chinese medicine doctor's memorial is Kam Wah Chung Museum in John Day,Oregon,U.S.,to commemorate Dr.Ing Hay(“Doc Hay”伍于念)and his business partner Lung On(梁光荣).There were few studies to explore Doc Hay's real practice and prescription,while most of papers focused on Doc Hay's legend life.This paper aims to analyze and interpret one of the intriguing herbal prescriptions that Doc Hay had hand-written.Materials and Methods:Dr.Arthur Yin Fan made an academic travel to Kam Wah Chung museum on August 5,2018 and examined the books and hand-written prescriptions of Doc Hay,which were not exhibited to the public at that time.This paper analyzes and interprets one of herbal prescriptions that Doc Hay had hand-written in 1907.Interpretation process included four steps:(1):Transform Doc Hay's hand-written prescription(with original herb names)to standard herb names in Chinese.(2):Induct and rearrange the herb name into groups based on herb property characteristics and then translate them into both PinYin names and English names.Analyzation of the prescription may include in what classic formula(s)routinely introduced in Chinese medicine textbooks.(3):Analyze the herbal action for each group and potential symptoms or conditions the patient may have had.An analysis of classic formula(s)used in the prescription may represent what clinical condition was being treated at that time.(4):Combine the analysis to give a comprehensive picture of the patient.Results:The prescription consists of 67 herbs,total 934.6 grams,and including Yin Qiao Powder(银翘散),Sang Ju Decoction(桑菊饮),Zhi Sou Powder(止嗽散),Qing Ying Decoction(清营汤),Xi Jiao Di Huang Decoction(犀角地黄汤),Long Dan Xie Gan Decoction(龙胆泻肝汤)and Chai Hu Shu Gan Powder(柴胡疏肝散).Speculation indicated that the prescription was for a patient who had obvious pulmonary infection accompanied by severe cough,and probably had prolonged pulmonary tuberculosis(TB)also with acute respiratory infection caused by other bacteria or viruses.Based on the analysis of composition of this prescription,it can be used for the treatment of epidemic diseases.Conclusion:The majority of herbs used in this prescription are commonly included in the herbal medicines in China used to effectively counter severe acute respiratory syndrome(SARS),H1N1 and currently COVID-19,it might be Doc Hay's basic formula for patients with“Spanish Flu”during the 1918-1920 pandemic.

Applicability of Zipfs Law in Traditional Chinese Medicine Prescriptions

Objective Traditional Chinese medicine(TCM)prescriptions have been used to cure diseases in China for thousands of years,in which many TCM herbs have no definite common quantity.Some key TCM herbs are commonly used and thus deserve in-depth investigations based on a more acceptable classification method.This study analyzes whether TCM prescriptions follow Zipf's law and attempts to obtain the thresholds of key TCM herbs based on the application of Zipfs law;Methods A total of 84,418 TCM prescriptions were collected and standardized.We tested whether Zipf's law and Zipfs distribution fit the Chinese herb distributions.A linear fitting experiment was performed to verify the relationship between the frequency distribution and frequency of TCM herbs.Results The distribution of TCM herbs in TCM prescriptions conformed to Zipf's law.Accordingly,the thresholds were obtained for the key TCM herbs.Conclusion The distribution of TCM herbs in TCM prescriptions follows Zipfs law.

The spatial-temporal evolution of coherent structures in log law region of turbulent boundary layer

The spatial-temporal evolution of coherent structures （CS） is significant for turbulence control and drag re- duction. Among the CS, low and high speed streak structures show typical burst phenomena. The analysis was based on a time series of three-dimensional and three-component （3D-3C） velocity fields of the flat plate turbulent boundary layer （TBL） measured by a Tomographic and Time-resolved PIV （Tomo TRPIV） system. Using multi-resolution wavelet transform and conditional sampling method, we extracted the intrinsic topologies and found that the streak structures appear in bar-like patterns. Furthermore, we seized locations and velocity information of transient CS, and then calculated the propagation velocity of CS based on spatial-temporal cross-correlation scanning. This laid a foundation for further studies on relevant dynamics properties.

Ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris based on data mining

Objective To explore ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris, and to provide new ideas for the clinical treatment.Methods With “angina pectoris” as the key word, ancient books prescriptions and Chinese patent medicines related to angina pectoris were collected from China National Knowledge Infrastructure(CNKI), Traditional Chinese Medicine Database System, Chinese Medicine Prescription Database, New National Proprietary Chinese Medicine(2 nd edition), and Chinese Pharmacopoeia(2020 edition) from January 1, 2015 to December 31, 2021. Core highfrequency aromatic Chinese medicines were defined, and their potential medication rules were analyzed and summarized. Microsoft Access 2010 was used for data management. Data analysis software, including Excel and IBM SPSS Modeler 18.0 were used for drug association rule analysis, and Cytoscape 3.7.2 for visual display.Results There were 67 ancient books prescriptions and 258 Chinese patent medicines containing aromatic Chinese medicines treating angina pectoris collected from relevant databases. In ancient books prescriptions, there were nine aromatic Chinese medicines with the frequency ≥10, and the most commonly used medicine was Danggui(Angelicae Sinensis Radix), followed by Chenpi(Citri Reticulatae Pericarpium). There were 33 aromatic Chinese medicines with the frequency ≥10 in Chinese patent medicines, and the most commonly used medicine was Danshen(Salviae Miltiorrhizae Radix et Rhizoma), followed by Chuanxiong(Chuanxiong Rhizoma) and Sanqi(Notoginseng Radix et Rhizoma). In ancient books prescriptions, the medicines mainly belonged to intenal-warming medicines, Qi-regulating medicines, and blood circulation promoting and blood stasis removing medicines.There were eight medicine pairs with confidence equal to 100% in ancient books prescriptions, the most frequently used pairs were Chuanxiong(Chuanxiong Rhizoma) +Danggui(Angelicae Sinensis Radix), and Xiangfu(Cyperi Rhizoma) + Chenpi(Citri Reticulatae Pericarpium). In Chinese patent medicines, the aromatic Chinese medicine Chuanxiong(Chuanxiong Rhizoma) could be combined with many other Chinese medicines, among which the Confidence and Support of Chuanxiong(Chuanxiong Rhizoma) + Danshen(Salviae Miltiorrhizae Radix et Rhizoma) were at a high level.Conclusion Aromatic Chinese medicines for the treatment of angina pectoris of coronary heart disease are mainly warm, and the flavors are mainly pungent, sweet, and bitter. They mainly access to the liver, gallbladder, and pericardium meridians. The treatment of angina pectoris of coronary heart disease mainly focuses on warming heart pulse, and promoting blood circulation and removing blood stasis.

Efficacy and educational role of a daily employment of the accelerometer to improve the life style in overweight-hypertensive population

The daily evaluation of the life style is funda- mental for the “exercise as prescription” to re- duce the cardiovascular risks factors. The reg- istration by an accelerometer can identify active from inactive subjects. The aim of the present study is to verify, in a small cohort of subjects at high risk level (obese–hypertensive), the health outcomes. A group of 22 subjects were evalu- ated by the questionnaire and also by an accel- erometer positioned on belt for 5 days to estab- lish the daily Physical Activity Level (PAL).The anthropometrics parameters, Body Mass Index (BMI), Waist Circumference, Hip Circumference, Fat Mass, Free Fat Mass, Total Body–Intracellular and Extracellular Water and Phase Angle (PA) were measured at the beginning and after 3 months of regular exercise. The amount of the exercise prescribed for three months and at least 3 times in a weak, was determined by the Cardiopulmonary test at the 60% of the VO2. Sta-tistical analysis included T-Student test for paired data with a significance at P < 0.05value. Respect of the questionnaire the accelerometer report showed a predominantly inactive life style (PAL = 1.49 ± 0.13). After three months the BMI was significantly reduced in all (p < 0.05) and in addi-tion a trend toward a reduction was also observed for Fatty Mass and for the body composition parameters. The employment of the accelerometer is therefore associated to an improvement of the parameters strongly related with the cardiovascular risk. The results obtained are suggestive for an educational role of this tool in subjects at high risk level.

Effects of Strain Rate and Fiber Content on the Dynamic Mechanical Properties of Sisal Fiber Cement-Based Composites

In this paper,a split Hopkinson pressure bar(SHPB)was used to investigate the dynamic impact mechanical behavior of sisal fiber-reinforced cement-based composites(SFRCCs),and the microscopic damage evolution of the composites was analyzed by scanning electron microscopy(SEM)and energy-dispersive X-ray spectrome-try(EDS).The results show that the addition of sisal fibers improves the impact resistance of cement-based composite materials.Compared with ordinary cement-based composites(OCCs),the SFRCCs demonstrate higher post-peak strength,ductility,and energy absorption capacity with higher fiber content.Moreover,the SFRCCs are strain rate sensitive materials,and their peak stress,ultimate strain,and energy integrals all increase with increasing strain rate.From the perspective of fracture failure characteristics,the failure of OCCs is dominated by the brittle failure of crystal cleavage.In contrast,the failure mode of the SFRCCs changes to microscale matrix cracks,multi-scale pull-out interface debonding of fibers(fine filaments and bundles),and mechanical interlock.This research provides an experimental basis for the engineering application of high-performance and green cement-based composites.

Mathematical Aspects of SU (2) and SO(3,R) Derived from Two-Mode Realization in Coordinate-Invariant Form

Some mathematical aspects of the Lie groups SU (2) and in realization by two pairs of boson annihilation and creation operators and in the parametrization by the vector parameter instead of the Euler angles and the vector parameter c of Fyodorov are developed. The one-dimensional root scheme of SU (2) is embedded in two-dimensional root schemes of some higher Lie groups, in particular, in inhomogeneous Lie groups and is represented in text and figures. The two-dimensional fundamental representation of SU (2) is calculated and from it the composition law for the product of two transformations and the most important decompositions of general transformations in special ones are derived. Then the transition from representation of SU (2) to of is made where in addition to the parametrization by vector the convenient parametrization by vector c is considered and the connections are established. The measures for invariant integration are derived for and for SU (2) . The relations between 3D-rotations of a unit sphere to fractional linear transformations of a plane by stereographic projection are discussed. All derivations and representations are tried to make in coordinate-invariant way.

A Novel Technique for Preparation of Electrically Conductive ABS/Cu Polymeric Gradient Composites

A novel technique for preparing functionally gradient electrically conductive polymeric composites was developed by using of solution casting technique on the principle of Stokes＇ law. Acrylonitrile- butadiene-styrene/Cu （ABS/Cu） gradient polymeric composites were prepared successfully using this technique. The gradient structures, electrically conductive performance and mechanical properties of the ABS/Cu composites were investigated. Optical microscope observation shows that the gradient distribution of Cu particles in ABS matrix was formed along their thickness-direction. The electrically conductive testing results indicate that the order of magnitude of surface resistivity was kept in 10^15 Ω at ABS rich side, while that declined to 10^5 Ω at Cu particles rich side, and the percolation threshold was in the range of 2.82 vo1%- 4.74 vol% Cu content at Cu particles rich side. Mechanical test shows that the tensile strength reduced insignificantly as the content of Cu increases owing to the gradient distribution.

An Exploration on Adaptive Iterative Learning Control for a Class of Commensurate High-order Uncertain Nonlinear Fractional Order Systems

This paper explores the adaptive iterative learning control method in the control of fractional order systems for the first time. An adaptive iterative learning control(AILC) scheme is presented for a class of commensurate high-order uncertain nonlinear fractional order systems in the presence of disturbance.To facilitate the controller design, a sliding mode surface of tracking errors is designed by using sufficient conditions of linear fractional order systems. To relax the assumption of the identical initial condition in iterative learning control(ILC), a new boundary layer function is proposed by employing MittagLeffler function. The uncertainty in the system is compensated for by utilizing radial basis function neural network. Fractional order differential type updating laws and difference type learning law are designed to estimate unknown constant parameters and time-varying parameter, respectively. The hyperbolic tangent function and a convergent series sequence are used to design robust control term for neural network approximation error and bounded disturbance, simultaneously guaranteeing the learning convergence along iteration. The system output is proved to converge to a small neighborhood of the desired trajectory by constructing Lyapnov-like composite energy function(CEF)containing new integral type Lyapunov function, while keeping all the closed-loop signals bounded. Finally, a simulation example is presented to verify the effectiveness of the proposed approach.

Elevated temperature compressive deformation behavior of 2024Al matrix composite reinforced by sub-micro Al_2O_3 particles

The compressive behavior of sub-micro Al2O 3P （40%, volume fraction）/2024Al composite was investigated within the temperature range from 270℃ to 620℃ under various strain rates from 0.00042s -1 to 0.14s -1. Results show that the critical compression reduction of the composite presents a saddle law under the combined influence of temperature and strain rate. That means the composites exhibit better deformation ability at higher temperature with higher strain rate （445℃, 0.14s -1） or at lower temperature with lower strain rate （320℃, 0.0042s -1）.

Oxidation of Al_2O_3-30%TiCN-0.2%Y_2O_3 Composite

The oxidation behavior of Al2O3-30%TiCN-0.2%Y2O3 composite and its effect on high temperature bending strength was studied. The result indicates that the mass gain during static oxidation of the material under normal atmosphere follows the parabolic law. Oxide increases with increasing temperature and prolonging time. It has good oxidation resistance. The product of oxidation of the material is TiO2. Therefore, the volume of the material expands. The oxide film is destroyed because residual stress inside the oxide film is released. Proper oxidation is beneficial to the improvement of bending strength of Al2O3-30%TiCN-0.2%Y2O3 composite. The strength increase is up to 4.5%.

Properties of frictional bridging in fiber pull-out for fiber-reinforced composites

Stress equilibrium equations, boundary- and continuity-conditions were used to establish a theoretical model of progressive debonding with friction at the debonded interface. On a basis of the minimum complementary energy principle, an expression for the energy release rate G was derived to explore the interfacial fracture properties. An interfacial debonding crite- rion G≥Γi was introduced to determine the critical debond length and the bridging law. Numerical calculation results for fi- ber-reinforced composite SCS-6/Ti-6Al-4V were compared with those obtained by using the shear-lag models.
