Using Qi flow in Taiji effecting structural change in feet and reduced pain: a case report

In the article, the author reports on a case study of chronic pain problems caused by her own foot deformity. The author began using Taiji, Chen style Chan Si Gong (Reeling Silk), and Zhan Zhuang (standing meditation) to relieve chronic pain since 1986. After more than two years of Qigong training, the structure of the author's foot changed from the previous deformity to normal foot shape. These changes enabled the author to walk normally and to be free from persistent chronic pain. The article discussed the methods of using Qi currents and other issues that need to be paid attention to when practicing Tai chi, such as how to adjust one's mental focus and maintain a state of relaxation to "mindful". Tai chi involves a number of internal "micro-adjusting" about how these techniques relax and strengthen muscles to reduce chronic pain. The report and discussion on the treatment principle of Qigong can provide new strategies for the treatment of chronic pain.

Extract and Simple Explanation on the Principles of Taiji Studies

Taiji studies are a field of study that has its roots in the philosophical thought of the Yi Jing or Book of changes.It integrates the self‑cultivation traditions of Confucianism,Buddhism,and Daoism,and centers its academic system mostly on the perspective of the“states view”(jing jie guan).From the standpoint of its philosophical theory,Taiji studies divide the understanding of Dao into three theoretical states:the state of existence(you jie),the state of existence‑nonexistence(you wu jie),and the state of nonexistence(wu jie).It also establishes a theoretical structure that mainly includes“three states and nine axioms,”“One Dao and Nine theory sections,”and“Three practice levels and Nine secrets.”Based on traditional Chinese culture and philosophy,Taiji studies are continuously integrating the essence of them for better understanding and raising,and finally set up a rational school of Taiji Da Dao。

Taiji Quan and Health

Taiji Quan is a Chinese martial art that combines self-defense with physical and mental fitness.It is practiced today primarily for its health benefits,stress relief and relaxation,although interest in the martial applications of the art is growing.The slow,continuous movements are designed to impart powerful physical skills and to stimulate the flow of energy within the body,with the ultimate goal of improved mind-body connection and increased longevity.

Healthcare and Sports from the Perspective of Qi,Fascia,and Taijiquan

The slow-motion practice of Taijiquan,operationally,cultivates the cognitive perception of fascia tension as it is being harnessed to discipline body motion to be in accord with Yin-Yang Balance.The ideal motion that results,bestows liveliness of change and harmonizes body momentum,the hallmarks of maneuverability and force potential for performance.The paper puts forth the proposition that the manifestation of Qi in Taijiquan is primarily the cognitive perception of fascial tension in the functional efficacy of bipedal balance for performance.Though the cultivated cognition may be subjective,the process of Qi nurturing is grounded on the reduction of the errors of imbalances,which carves a practice path to balance with tangible effects.The force that arises from body motion so imbued with Yin-Yang Balance,is of the phenomenon of internal strength or neijin—consummate,of the right force vector in spontaneous response and rooted in balance.Taijiquan practice nurtures Qi for both health wellbeing and neijin as the body's core strength,depending on the practice efforts put in.

Taiji data challenge for exploring gravitational wave universe

The direct observation of gravitational waves(GWs)opens a new window for exploring new physics from quanta to cosmos and provides a new tool for probing the evolution of universe.GWs detection in space covers a broad spectrum ranging over more than four orders of magnitude and enables us to study rich physical and astronomical phenomena.Taiji is a proposed space-based gravitational wave(GW)detection mission that will be launched in the 2030s.Taiji will be exposed to numerous overlapping and persistent GW signals buried in the foreground and background,posing various data analysis challenges.In order to empower potential scientific discoveries,the Mock Laser Interferometer Space Antenna(LISA)data challenge and the LISA data challenge(LDC)were developed.While LDC provides a baseline framework,the first LDC needs to be updated with more realistic simulations and adjusted detector responses for Taiji’s constellation.In this paper,we review the scientific objectives and the roadmap for Taiji,as well as the technical difficulties in data analysis and the data generation strategy,and present the associated data challenges.In contrast to LDC,we utilize second-order Keplerian orbit and second-generation time delay interferometry techniques.Additionally,we employ a new model for the extreme-mass-ratio inspiral waveform and stochastic GW background spectrum,which enables us to test general relativity and measure the non-Gaussianity of curvature perturbations.Furthermore,we present a comprehensive showcase of parameter estimation using a toy dataset.This showcase not only demonstrates the scientific potential of the Taiji data challenge(TDC)but also serves to validate the effectiveness of the pipeline.As the first data challenge for Taiji,we aim to build an open ground for data analysis related to Taiji sources and sciences.More details can be found on the official website(taiji-tdc.ictp-ap.org).

祛魅与返魅:太极拳技击的理性审视

太极拳技击的发展演进是太极拳技击形象从祛魅走向返魅的逻辑进程。以马克斯·韦伯的祛魅理论为切入点,运用文献资料、历史研究、逻辑推理等研究方法,理性审视传统太极拳技击的祛魅历程及其所引发的危机,进而提出现代太极拳技击形象的返魅路径。研究认为:(1)“克力斯玛”光环加持、操化传习与对抗的“缺席”以及技击的“求巧”指向使得传统太极拳技击的祛魅化发展成为历史的必然选择。(2)学术祛魅与实践祛魅共同构成了两条太极拳技击的演进脉络,并引发了对太极拳技击的信任崩塌、技击技术至上主义盛行等危机。(3)现代太极拳技击形象的返魅理路应以太极推手项目为抓手,彰显太极拳技击之门内形象;以综合格斗竞技场、警务实战为应用平台,重塑太极拳技击之门外形象。

Clinical study of Taiji needling in treatment of peripheral facial neuritis

Objective To observe the clinical efficacy of Taiji needling in treatment of peripheral facial neuritis. Methods Sixty inpatients with peripheral facial neuritis were randomly divided into two groups： observation group （Taiji needling group, n=30） and control group （conventional acupuncture group, n=30）; the treatment was conducted once a day, which was not stopped until the patients were discharged from hospital after recovery. The curative effect was evaluated before and after treatment by applying the therapeutic outcome rating scale of peripheral facial neuritis （portmann scale）. Results The improve merit of efficacy indices in the observation group was superior to that in the control group, and the difference was statistically significant （P〈0.05）; the course of treatment was shortened in the observation group compared with the control group, and the difference was also statistically significant （P〈0.05）. Conclusion The efficacy index of Taiji needling in treatment of peripheral facial neuritis is superior to that of conventional acupuncture, and Taiji needling can obviously shorten the course of treatment.

Prospects for improving cosmological parameter estimation with gravitational-wave standard sirens from Taiji

Taiji,a space-based gravitational-wave observatory,consists of three satellites forming an equilateral triangle with arm length of 3×10^6 km,orbiting around the Sun.Taiji is able to observe the gravitationalwave standard siren events of massive black hole binary(MBHB)merger,which is helpful in probing the expansion of the universe.In this paper,we preliminarily forecast the capability of Taiji for improving cosmological parameter estimation with the gravitational-wave standard siren data.We simulate fiveyear standard siren data based on three fiducial cosmological models and three models of MBHB’s formation and growth.It is found that the standard siren data from Taiji can effectively break the cosmological parameter degeneracies generated by the cosmic microwave background(CMB)anisotropies data,especially for dynamical dark energy models.The constraints on cosmological parameters are significantly improved by the data combination CMB+Taiji,compared to the CMB data alone.Compared to the current optical cosmological observations,Taiji can still provide help in improving the cosmological parameter estimation to some extent.In addition,we consider an ideal scenario to investigate the potential of Taiji on constraining cosmological parameters.We conclude that the standard sirens of MBHB from Taiji will become a powerful cosmological probe in the future.
