1Video-based running water animation in Chinese painting style显示文摘This paper presents a novel algorithm for synthesizing animations of running water,such as water-falls and rivers,in the style of Chinese paintings,for applications such as cartoon making. All video frames are first registered in a common coordinate system,simultaneously segmenting the water from background and computing optical flow of the water. Taking artists’ advice into account,we produce a painting structure to guide painting of brush strokes. Flow lines are placed in the water following an analysis of variance of optical flow,to cause strokes to be drawn where the water is flowing smoothly,rather than in turbulent areas: this allows a few moving strokes to depict the trends of the water flows. A variety of brush strokes is then drawn using a template determined from real Chinese paintings. The novel contributions of this paper are:a method for painting structure generation for flows in videos,and a method for stroke placement,with the necessary temporal coherence.ZHANG SongHai CHEN Tao ZHANG YiFei HU ShiMin MARTIN Ralph 2009Science in China(Series F)2009,52,2:8

5The Involvement of Lipids in Alzheimer's Disease显示文摘It has been estimated that Alzheimer's disease(AD), the most common form of dementia, will affect approximately 81 million individuals by 2040. To date, the actual cause and cascade of events in the progression of this disease have not been fully determined.Furthermore, there is currently no definitive blood test or simple diagnostic method for AD. Considerable efforts have been put into proteomic approaches to develop a diagnostic blood test, but to date these efforts have not been successful. More recently, there has been a stronger focus on lipidomic studies in the hope of increasing our understanding of the underlying mechanisms leading to AD and developing an AD blood test. It is well known that the strongest genetic risk factor for AD is the ε4 variant of apolipoprotein E(APOE).Evidence suggests that the ApoE protein, a major lipid transporter, plays a key role in the pathogenesis of AD, and its role in both normal and aberrant lipid metabolism warrants further extensive investigation. Here, we review ApoE-lipid interactions, as well as the roles that lipids may play in the pathogenesis of AD.Wei Ling Florence Lim Ian James Martins Ralph Nigel Martins 2014Journal of Genetics and Genomics2014,41,5:6
6Tribological behaviors of Ni-modified citric acid carbon quantum dot particles as a green additive in polyethylene glycol显示文摘A novel green lubricating oil additive(carbon quantum dot(CQD)particle‐doped nickel(Ni‐CQD))was synthesized from citric acid and nickel acetate.The effects of CQD and Ni‐CQD nanoparticles on the tribological behaviors of polyethylene glycol(PEG200)were investigated under different loads and reciprocation speeds.The results indicate that CQD and Ni‐CQD particles can both enhance the lubrication properties of PEG200.However,the Ni‐CQD nanoparticles enhanced the lubrication properties more than the plain CQD particles did.The average friction coefficient and wear rate of PEG200 containing 2 wt%Ni‐CQDs were reduced by 35.5%and 36.4%,respectively,compared to PEG200 containing pure CQDs under a load of 8 N and reciprocation speed of 25 mm/s over 60 min.The friction and wear mechanisms are attributed to the fact that friction induces the Ni‐CQDs to participate in the formation of a tribofilm,resulting in a low friction coefficient and wear rate.Zhiqiang TU Enzhu HU Bangbang WANG Karl D DAVID Philipp SEEGER Martin MONEKE Ralph STENGLER Kunhong HU Xianguo HU 2020Friction2020,8,1:5
7Evolution of stereoscopic imaging in surgery and recent advances显示文摘In the late 1980s the first laparoscopic cholecystectomies were performed prompting a sudden rise in technological innovations as the benefits and feasibility of minimal access surgery became recognised.Monocular laparoscopes provided only two-dimensional(2D) viewing with reduced depth perception and contributed to an extended learning curve.Attention turned to producing a usable three-dimensional(3D) endoscopic view for surgeons;utilising different technologies for image capture and image projection.These evolving visual systems have been assessed in various research environments with conflicting outcomes of success and usability,and no overall consensus to their benefit.This review article aims to provide an explanation of the different types of technologies,summarise the published literature evaluating 3D vs 2D laparoscopy,to explain the conflicting outcomes,and discuss the current consensus view.Katie Schwab Ralph Smith Vanessa Brown Martin Whyte Iain Jourdan 2017World Journal of Gastrointestinal Endoscopy2017,9,8:4

12Expressive line drawings of human faces from range images显示文摘We propose a novel technique to extract features from a range image and use them to produce a 3D pen-and-ink style portrait similar to a traditional artistic drawing. Unlike most previous template-based,component-based or example-based face sketching methods,which work from a frontal photograph as input,our system uses a range image as input. Our method runs in real-time for models of moderate complexity,allowing the pose and drawing style to be modified interactively. Portrait drawing in our system makes use of occluding contours and suggestive contours as the most important shape cues. However,current 3D feature line detection methods require a smooth mesh and cannot be reliably applied directly to noisy range images. We thus present an improved silhouette line detection algorithm. Feature edges related to the significant parts of a face are extracted from the range image,connected,and smoothed,allowing us to construct chains of line paths which can then be rendered as desired. We also incorporate various portrait-drawing principles to provide several simple yet effective non-photorealistic portrait renderers such as a pen-and-ink shader,a hatch shader and a sketch shader. These are able to generate various life-like impressions in different styles from a user-chosen viewpoint. To obtain satisfactory results,we refine rendered output by smoothing changes in line thickness and opacity. We are careful to provide appropriate visual cues to enhance the viewer’s comprehension of the human face. Our experimental results demonstrate the robustness and effectiveness of our approach,and further suggest that our approach can be extended to other 3D geometric objects.HUANG YueZhu MARTIN Ralph R.

14范式未成?再论社会网络研究的动态稳定性显示文摘本文提倡基于关系优先、普遍的嵌入性、网络连结的社会效用以及社会生活结构模式构成的一组核心概念(Lakatos,1970)来渐进式地发展理论,而非统一范式。组织网络研究可以捕捉个体和网络在相互建构与变化方面的复杂性和区别性。本文的目标不是描述已预设结果的细微难题,而是勾画一些与新兴现象相关的大胆设想。Martin Kilduff Wenpin Tsai Ralph Hanke 李永强(译) 车瑜(译) 曾媛媛(译) 2013经济管理2013,39,6:2
