Analysis on the distinguishing features of traditional Chinese therapeutics and related statistical issues

Jingqing Hu, Jie Qiao, Deying Kang, Baoyan Liu

Frontiers of Medicine 2011, Volume 5, Issue 2,   Pages 203-207 doi: 10.1007/s11684-011-0138-6

Abstract: Traditional Chinese medicine (TCM) is one of the rarely existing ancient traditional medicines that hold systematic theories as well as preventative and therapeutic methods for diseases in practice. From the 1950s, such research methods as mathematics, statistics, and data mining (DM) have been gradually introduced to TCM studies, making it more scientific. Meanwhile, the distinct features of TCM theories and diagnostic-model have constantly challenged the methodology of statistics. This paper introduces the following scientific features of traditional Chinese therapeutics: 1) its goal is to balance the functions and conditions of human body; 2) it emphasizes on holism and individualization; 3) it stresses the longitudinal regulation and evaluation mode, which is a circle of syndrome diagnosis, treatment and evaluation; 4) the interventions of TCM are abundant, compound and natural; and 5) humanistic thought is everywhere. Some statistical problems are raised based on these features. First, complex statistical methods that can analyze subjective indexes and latent variables, multidimensional and multistage data, non-equilibrium designed studies, and longitudinal data are required. Second, comprehensive evaluation on multiple-target mechanism has been brought in by combination treatment. Third, there is a need to analyze how humanity and related cultural factors may influence the effect of interventions. Thus, promoting implemented studies of statistics as well as carrying out the TCM scientific propositions have become the common expectations of both TCM and modern medicine.

Liver surgery and transplantation in China: Progress and Challenges

LAU W Y, LAI E C H

Frontiers of Medicine 2007, Volume 1, Issue 1,   Pages 1-5 doi: 10.1007/s11684-007-0001-y

Abstract: From the limited but available information, we traced the history of developments of liver surgery and transplantation in China. Liver surgery first started in the late 1950s in China, and it soon flourished mainly because of the great demand in liver surgery and the emergence of a number of giants in liver surgery. We recognized and honoured the important contributions of these Chinese pioneers in portal hypertension, recurrent pyogenic cholangitis, hepatocellular carcinoma and liver transplantation.

Ground movements due to deep excavations in Shanghai: Design charts

VARDANEGA,Charles W. W. NG,Xianfeng MA

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 3,   Pages 201-236 doi: 10.1007/s11709-014-0253-y

Abstract: Recent research has clarified the sequence of ground deformation mechanisms that manifest themselves when excavations are made in soft ground. Furthermore, a new framework to describe the deformability of clays in the working stress range has been devised using a large database of previously published soil tests. This paper aims to capitalize on these advances, by analyzing an expanded database of ground movements associated with braced excavations in Shanghai. It is shown that conventional design charts fail to take account either of the characteristics of soil deformability or the relevant deformation mechanisms, and therefore introduce significant scatter. A new method of presentation is found which provides a set of design charts that clarify the influence of soil deformability, wall stiffness, and the geometry of the excavation in relation to the depth of soft ground.

Robotized machining of big work pieces: Localization of supporting heads

Wojciech SZYNKIEWICZ, Teresa ZIELIŃSKA, Włodzimierz KASPRZAK

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4,   Pages 357-369 doi: 10.1007/s11465-010-0103-0

Abstract: A planner for a self adaptable and reconfigurable fixture system is proposed. The system is composed of mobile support agents that support thin sheet metal parts to minimize part dimensional deformation during drilling and milling operations. Compliant sheet metal parts are widely used in various manufacturing processes including automotive and aerospace industries. The main role of the planner is to generate an admissible plan of relocation of the mobile agents. It has to find the admissible locations for the supporting heads that provide continuous support in close proximity to the tool and trajectories of the mobile bases characterized by very high speeds during the relocation phases.

Barriers to advancing nanotechnology to better improve and translate nanomedicines

Yuwei WANG,David W. Grainger

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 3,   Pages 265-275 doi: 10.1007/s11705-014-1442-x

Abstract: Engineered nanomaterials and nanotechnologies promise many benefits to enhance both and performance. This is now manifest in the increasing number of reported biomedical products under development and testing that contain nanotechnologies as their distinguishing performance—enhancing components. In many cases, nano-sized materials are selected to provide a specific functional aspect that contributes to improved medical performance, either or . Nanoparticles are most commonly exploited in diverse roles in topical lotions and creams, solubilization aids, for and diagnostic and targeting agents in nanomedicines and theranostics. Despite fundamental scientific excitement and many claims to nanotechnology-based improvements in new biomedical applications, several fundamental and long-standing challenges remain to be addressed using nanomedicines to make clinically important progress. This review addresses several issues that must be fairly and objectively reported and then overcome to provide truly credible performance for nanomedicines.

Evolving perspectives on biofuels in the United States

DIRKS, Gary W. DIRKS, Jianguo WU

Frontiers in Energy 2012, Volume 6, Issue 4,   Pages 379-393 doi: 10.1007/s11708-012-0213-y

Abstract: Biofuels represent an important source of renewable energy and may play a crucial role in developing sustainable energy strategies for many countries and the world as a whole. The pros and cons of biofuels, however, have been debated both scientifically and politically. They remain a topic of controversy. In this paper, the evolvement of the perspectives and policies on biofuels in the United States in the past several decades was reviewed. Four different periods, that is, the period prior to 1978 (marked by the passage of the Energy Act in 1978); 1978–1989 (ending with the passage of the Clean Air Act Amendments of 1990); 1990–2004 (ending with the passage of the energy act of 2005); and 2005 to the present, which were characterized by defining events of major policy importance were identified. Each time period was assessed using the Ostrom institutional analysis and development (IAD) framework to show the impact of the evolving interests and influences of global players on policy choices related to biofuels in the United States. The US has a long history of supporting corn-based ethanol and more recently advanced biofuels. Changes in perspectives on biofuels from largely unrelated groups led to changes in policy and market dynamics. Until the late 1990s, most perspectives and policies tended to be aligned and significantly supportive of corn-based ethanol in the United States. In the early 2000s, it became clear that the complications associated with first generation biofuels and corn-based ethanol in particular, were too numerous and too severe to overlook. The need for better options has spurred interest in new technologies and more environmentally benign feedstocks, but, there is little prospect for biofuels playing a significant role in the near term without greater alignment among key players.

Changes in hourly precipitation may explain the sharp reduction of discharge in the middle reach of the Yellow River after 2000

Lin LUO, Zhongjing WANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5,   Pages 756-768 doi: 10.1007/s11783-013-0563-7

Abstract: The Hekou-Longmen reach, together with local floods, is the main source area for coarse sedimentations into the Yellow River. When total rainfall slightly increased in the area, discharge dramatically decreased by 40%–70% after the year of 2000, and attracting extensive attention in the context of global climate change. High temporal resolution precipitation (timescales between 1 and 4 h) data from the June to September period from 270 rain gauges over the past three decades was mined in order to help explain the phenomenon. Each rainfall event was classified as light/moderate rain, large rain, heavy rain or rainstorm by the event’s rainfall amount, and further classified as low intensity rain, medium intensity rain and high intensity rain by the event’s rainfall intensity. The Mann-Kendall trend test was applied to detect the presence and significance of monotonic trends, and to find the change points in the mean and variance of the precipitation characteristics series, including the amount, intensity, frequency and duration of each rainfall category. Results show that although the total amount of precipitation has slightly increased, the average rainfall intensity has significantly decreased. The larger change happened in light/moderate rain events and low/medium intensity rain events, and the intensity changes have a great extent occurred around the threshold of Non-Runoff Rainfall regime, which was proposed for the approximate calculation of initial losses. Changes in rainfall distribution between different classes of the Runoff Rainfall regime in the 2000s could lead to 0.9 mm less runoff depth (17.3% of the total reduction) than the 1980–1999 period. The study indicates that changes in hourly precipitation may be responsible for the sharp reduction of discharge.
