An easy method using glutaraldehyde-introduced fluorescence for the microscopic analysis of plant biotrophic interactions

The method introduced in this article makes use of the glutaraldehyde-induced auto-fluorescence of proteins after cross-linking with glutaraldehyde for the analysis of cellular and sub-cellular structures. Because the interface of biotrophic interactions is rich in proteins, the method presented is particularly suitable for the analysis of such interactions; we have exemplified its usefulness by analyzing (1) the root feeding sites induced in roots from Arabidopsis thaliana by the root-knot nematode Meloidogyne incognita ; (2) leaves from Cucurbita pepo infected by powdery mildew and (3) roots from Nicotiana tabacum colonized by the arbuscular mycorrhizal fungus Glomus intraradices . The use of confocal and multi-photon laser scanning microscopy allows three-dimensional reconstructions from optical sections of complex biotrophic interactions. In the case of root-knot nematode feeding sites, our method enabled us to simultaneously study the development of the plant xylem elements (using lignin auto-fluorescence), the nematode feeding site and the nematode itself.

Subdivision Surfaces with Creases and Truncated Multiple Knot Lines

We deal with subdivision schemes based on arbitrary degree B‐splines. We focus on extraordinary knots which exhibit various levels of complexity in terms of both valency and multiplicity of knot lines emanating from such knots. The purpose of truncated multiple knot lines is to model creases which fair out. Our construction supports any degree and any knot line multiplicity and provides a modelling framework familiar to users used to B‐splines and NURBS systems.     

谈服装造型中的“线”

本文从服装的结构线、装饰线、外型轮廓线三方面论述了服装在三维空间中,最能扣住人们视线的首先是轮廓线,而轮廓线与人体结合,显示出肩、腰、臀的各自差别与变化,这些变化基于人体的比例,同时也可改变人体的比例而产生特殊的视觉效果。说明了完美的造型,适当的比例,往往是依靠分割线来进行的。轮廓结、结构线和装饰线,它们三者是相互联系而形成服装美感的。     

Universe分解中纽结的孤立性

给出了孤立纽结分解的定义,所谓孤立的（非平凡）纽结分解,即在不改变投影的前提下,universe分解中的该纽结改变其任何一个交叉都是平凡纽结。通过分析和讨论各种可能情形,回答了二重点为”（≤5）的素universe分解中是否存在孤立的交叉数为”的非平凡纽结分解的问题。     

李贺的“苏小小情结”

李贺是中唐时期优秀的诗人,他的诗以善写鬼、魂灵著称。作为有文学价值的妓女形象,苏小小对后世文人有很大影响,可以说有一个苏小小情结存在,李贺也不例外。苏小小在其诗中共出现两次,这种出现不是偶然,而是诗人找寻异代知己的认同感所致。     

An influence-knot set based new local refinement algorithm for T-spline surfaces

Local refinement is widely applied in surface modeling. This paper proposes the concept of influence knot set, and uses it to establish a new algorithm for the local refinement of T-spline surfaces, whose effectiveness is demonstrated by several examples. Compared with existing algorithms, the present one may have two advantages: (a) it does not produce excessive propagation of control points because the number of additional control points is reduced; (b) it simplifies the process of judging whether an additional control point needs to be added or not, and so the final T-mesh topology can be obtained more easily.     

Data based segmentation and summarization for sensor data in semiconductor manufacturing

In semiconductor manufacturing processes, sensor data are segmented and summarized in order to reduce storage space. This is conventionally done by segmenting the data based on predefined chamber step information and calculating statistics within the segments. However, segmentation via chamber steps often do not coincide with actual change points in data, which results in suboptimal summarization. This paper proposes a novel framework using abnormal difference and free knot spline with knot removal, to detect actual data change points and summarize on them. Preliminary experiments demonstrate that the proposed algorithm handles arbitrarily shaped data in a robust fashion and shows better performance than chamber step based segmentation and summarization. An evaluation metric based on linearity and parsimony is also proposed.
