Decreasing complexity of glucose time series derived from continuous glucose monitoring is correlated

《医学前沿（英文）》 2023年第17卷第1期页码 68-74 doi: 10.1007/s11684-022-0955-9

摘要： Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual’s health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique “continuous glucose monitoring” (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

CAS and ABM-based Demolition Waste Management Research in the AEC Industry

Zhi-kun Ding,Yi-fei Wang,Jin-chuang Wu

《工程管理前沿（英文）》 2016年第3卷第1期页码 18-23 doi: 10.15302/J-FEM-2016004

摘要： With the increase of the urban population and the rapid development of urbanization in China, a large number of old buildings will be demolished and produce a huge amount of waste. Currently the recycling ratio of old building materials is very low, which results in the problems of resource waste and environment pollution. This greatly challenges urban sustainable development. With respect to the continual growth of demolition waste quantities, it is urgent to research how to implement effective management of demolition wastes by focusing on the demolition agents’ behavior. Based on the theory of complexity, this paper analyzes the demolition waste management from the perspective of complex adaptive system. Taking into account the “green” demolition (building dismantling) and conventional demolition (building demolished) methods, the agent-based modeling method with Repast Simphony platform is applied to simulate interactions between demolition agents. The longitudinal trend of demolition waste quantities is forecasted.

摘要：

Traditional Chinese medicine (TCM) has been gradually accepted by the world. Despite its widespread use in clinical settings, a major challenge in TCM is to study it scientifically. This difficulty arises from the fact that TCM views human body as a complex dynamical system, and focuses on the balance of the human body, both internally and with its external environment. As a result, conventional tools that are based on reductionist approach are not adequate. Methods that can quantify the dynamics of complex integrative systems may bring new insights and utilities about the clinical practice and evaluation of efficacy of TCM. The dynamical complexity theory recently proposed and its computational algorithm, Multiscale Entropy (MSE) analysis, are consistent with TCM concepts. This new system level analysis has been successfully applied to many health and disease related topics in medicine. We believe that there could be many promising applications of this dynamical complexity concept in TCM. In this article, we propose some promising applications and research areas that TCM practitioners and researchers can pursue.

Managing Coordination Complexity in the Remanufacturing of Aircraft Engines

Qing Yang,Lu Zheng

《工程管理前沿（英文）》 2016年第3卷第2期页码 158-164 doi: 10.15302/J-FEM-2016022

摘要： The complexity of communication and coordination stemming from teams responsible for adjusting interdependent parameters of components is a fundamental feature in the aircraft engine remanufacturing engineering project. To manage coordination complexity, the features of the remanufacturing process of aircraft engine are analyzed and a systematic method is presented to measure and optimize the dependency between coupled components. Furthermore, quantitative models are built based on Design Structure Matrix (DSM) models to measure dependency strengths related to the parameter features of the components. Also, a two-stage DSM clustering criteria is used to reduce the complexity of an organization. An industrial example is provided to illustrate the proposed models. The results showed that the proposed approach can reduce total coordination complexity.

创建新医学的思考

马蔼乃,赵少奎

《中国工程科学》 2007年第9卷第10期页码 19-23

摘要：

西医以实证科学为基础，以分解、还原为主要方法，分工越来越精细，获得了许多医学上的成就，也治愈了许多疾病，但是强调治病，对人的因素重视不够，在维护整个人体健康方面遇到了某些困惑。中医把人看成“天、地、人”三位一体的整体，从辨证恒动的观点出发，以实践为基础，实施综合、整体治疗，也获得许多医学上的成就，治愈了许多疾病，但是主要凭感觉，取象比类等方法诊治病人，缺乏实证科学的基础。半个多世纪以来，提倡中西医结合，有一定成效。在钱学森系统科学思想的指导下，依照“突破还原论，发展整体论，达到两者辩证统一的系统论”的哲学理念，提出了中西医的结合点——人体生态系统。人体生态系统是以人体系统为中心与人体之外的环境构成一个整体的复杂系统，针对“人”是一个开放的复杂巨系统，运用综合集成创新的思路，提出了创建新医学——人体生态医学的构想。

Traditional Chinese medicine: potential approaches from modern dynamical complexity theories

《医学前沿（英文）》 2016年第10卷第1期页码 28-32 doi: 10.1007/s11684-016-0434-2

摘要：

Despite the widespread use of traditional Chinese medicine (TCM) in clinical settings, proving its effectiveness via scientific trials is still a challenge. TCM views the human body as a complex dynamical system, and focuses on the balance of the human body, both internally and with its external environment. Such fundamental concepts require investigations using system-level quantification approaches, which are beyond conventional reductionism. Only methods that quantify dynamical complexity can bring new insights into the evaluation of TCM. In a previous article, we briefly introduced the potential value of Multiscale Entropy (MSE) analysis in TCM. This article aims to explain the existing challenges in TCM quantification, to introduce the consistency of dynamical complexity theories and TCM theories, and to inspire future system-level research on health and disease.

Epithelial-to-mesenchymal transition in cancer: complexity and opportunities

Yun Zhang, Robert A. Weinberg

《医学前沿（英文）》 2018年第12卷第4期页码 361-373 doi: 10.1007/s11684-018-0656-6

摘要：

The cell-biological program termed the epithelial-to-mesenchymal transition (EMT) plays an important role in both development and cancer progression. Depending on the contextual signals and intracellular gene circuits of a particular cell, this program can drive fully epithelial cells to enter into a series of phenotypic states arrayed along the epithelial-mesenchymal phenotypic axis. These cell states display distinctive cellular characteristics, including stemness, invasiveness, drug-resistance and the ability to form metastases at distant organs, and thereby contribute to cancer metastasis and relapse. Currently we still lack a coherent overview of the molecular and biochemical mechanisms inducing cells to enter various states along the epithelial-mesenchymal phenotypic spectrum. An improved understanding of the dynamic and plastic nature of the EMT program has the potential to yield novel therapies targeting this cellular program that may aid in the management of high-grade malignancies.

An improved low-complexity sum-product decoding algorithm for low-density parity-check codes

Michaelraj Kingston ROBERTS,Ramesh JAYABALAN

《信息与电子工程前沿（英文）》 2015年第16卷第6期页码 511-518 doi: 10.1631/FITEE.1400269

摘要： In this paper, an improved low-complexity sum-product decoding algorithm is presented for low-density parity-check (LDPC) codes. In the proposed algorithm, reduction in computational complexity is achieved by utilizing fast Fourier transform (FFT) with time shift in the check node process. The improvement in the decoding performance is achieved by utilizing an optimized integer constant in the variable node process. Simulation results show that the proposed algorithm achieves an overall coding gain improvement ranging from 0.04 to 0.46 dB. Moreover, when compared with the sum-product algorithm (SPA), the proposed decoding algorithm can achieve a reduction of 42%-67% of the total number of arithmetic operations required for the decoding process.

Grasping institutional complexity in infrastructure mega-projects through the multi-level governance

Yi HU, Yun LE, Xinglin GAO, Yongkui LI, Mingqiang LIU

《工程管理前沿（英文）》 2018年第5卷第1期页码 52-63 doi: 10.15302/J-FEM-2018074

摘要： This study analyzes the design and operation of multi-level governance system for the smooth delivery of infrastructure mega-projects with high institutional complexity caused by market transition. From an institutional perspective, this study scrutinizes the structure, elements, and dynamics of the governance system of infrastructure mega-projects and then proposes an integrative framework based on the inductive case study of the Hong Kong-Zhuhai-Macao Bridge mega-project. Multiple evidences of archives, field studies, and interviews related to the case project are triangulated to further analyze the institutional effects, specifically those with government logics and market structures, on the design and operation of the three-level governance system. Results reveal that the co-evolution between governments and markets in China has shaped the vertical levels of the mega-project governance system and has further affected their evolution and operation across various stages of project development. This study contributes to the rapidly emerging research on complex system governance by proposing a systematic model of three-level mega-project governance to enhance the timely delivery of infrastructure mega-projects within budget.

从复杂性看科学发展观

苗东升

《中国工程科学》 2005年第7卷第8期页码 1-8

摘要：

发展观指人们对社会发展的目标、动力、模式、规律等的根本看法，其复杂性涉及四个层面：在对象层面上，发展观的复杂性源于社会是特殊的开放复杂巨系统；在认知层面上，认知过程的复杂性源于思维巨系统的复杂性与习以为常的还原论和非系统思维带来的曲解；在实践层面上，落实发展观的复杂性源于现实的利益格局、现行体制中的不完善、国际关系的复杂性等因素；在哲学层面上，发展观的复杂性源于发展过程包含的大量对立统一，只有对它们统筹兼顾，确保矛盾各方全面协调发展，才是科学的。
