Stereology as inverse problem
Stereology is the part of imaging science in which the three-dimensional structure of a body is determined from two-dimensional views. Although it is relatively easy to determine volume information from 2-D slices, it is nontrivial in general to determine other physical properties such as internal surface areas unless the medium is known to have some simple symmetry such as isotropy. For this r...
متن کاملMonoclonal Antibodies to Quantitate
content in L2 lung cells and WI-38 fibroblasts cultivated under hypoxic and normoxic conditions. After 96 h of hypoxic cultivation, PyKi activity was significantly increased in both cell types (L2: normoxia [Po2 = 142 torr], 0.11+0.01 [SD]; hypoxia [Po2 = 14 torr], 0.25 ±0.04 U/,ug DNA, P < 0.01). PyKi content increased proportionately in both cell lines (L2: normoxia, 0.44 +0. 13; hypoxia, 0.9...

1.1 組織標本を使用する定量解析が抱える諸問題 組織標本の解析は定性的な所見から始まる.顕微鏡を用いた丁寧な観察によって初めて得られる検体の 大きさや分布,形態などについての詳細な情報は,全ての研究の基礎となるべき重要なものである.しか しながら,定性的なデータだけでは,統計学的な検討が難しく,結果が主観的なものになりやすい.この ため,生理的組織と病的組織の比較など,さらなる研究を行う際には,定量的なデータが必要になる.定 量解析の基本的な命題は,いかにして検体の正確な数を客観的に求めることができるか,ということであ る.組織標本に基づく定量解析は単純に思われるが,正確なデータを得ることは実は容易ではない. 最大の問題は,サンプリングバイアスである(図1).これは,標本抽出の際に母集団を代表していない 検体が選ばれるために生じる偏りのことであり,2次元的な切片を使って定量解析を行...
متن کاملProcedural Modeling as an Analytical Tool for 3D Survey in Urban Design Assessment
This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...
متن کاملBIM as Design Exploration Tool in Architecture
Recent developments in contemporary architecture have been significantly influenced by the emergence of digital technologies as a primary production tool allowing for new ways of thinking. These new developments, combined with research into new materials and fabrication technologies, make possible to purse imaginative designs that were not possible in the past. While often criticized for its ov...
