Super-accuracy and super-resolution getting around the diffraction limit.
In many research areas such as biology, biochemistry, and biophysics, measuring distances or identifying and counting objects can be of great importance. To do this, researchers often need complicated and expensive tools in order to have accurate measurements. In addition, these measurements are often done under nonphysiological settings. X-ray diffraction, for example, gets Angstrom-level stru...
متن کاملArthropods: developmental diversity within a (super) phylum.
The expression patterns of developmental genes provide new markers that address the homology of body parts and provide clues as to how body plans have evolved. Such markers support the idea that insect wings evolved from limbs but refute the idea that insect and crustacean jaws are fundamentally different in structure. They also confirm that arthropod tagmosis reflects underlying patterns of Ho...
متن کاملSuper - Diversity and the Prosperous Society
This article asks if and under what conditions ethnic diversity could become a foundation for a prosperous society. Recent studies on ethnic diversity and social cohesion suggest that diversity has a negative effect on social cohesion and therefore is detrimental to the social prosperity of individuals and communities. This paper argues that although such a negative correlation may apply to con...
متن کاملReconstruction-Based Super-Resolution Using Self-Congruency around Image Edges
テレビやパソコンにおける表示,プリンタによる印 刷などの画素密度が増加し,画像の解像度感が画質を 決めるポイントの一つになっている.これら出力機器 に対して画像データの画素が少ない場合,事前に信号 処理により画素を増やす高解像度化技術が必要となる. 従来の高解像度化技術としては,双一次内挿法,あ るいは三次畳込み内挿法 [1]~[3]など標本化定理に基 づく補間フィルタを用いることが多かった.しかし, これらの手法では画素が増えた画像で表現が可能にな る高い周波数成分は生成されず,出力画像はぼやけた ものになってしまう.そこで,補間フィルタの改良が 検討され [4], [5],例えば,Kim らは,Winscale とい う面積画素モデルに基づく手法を提案した [6].簡単な 処理で最近傍内挿と双一次内挿の性質を併せもつ拡大 を行うが,高い解像度感は得られない.また,エッジ 適応型内...
متن کاملPlanet Formation around Stars of Various Masses: Hot Super-earths
We consider trends resulting from two formation mechanisms for short-period super-Earths: planetplanet scattering and migration. We model scenarios where these planets originate near the snow line in “cold finger” circumstellar disks. Low-mass planet-planet scattering excites planets to low periastron orbits only for lower mass stars. With long circularisation times, these planets reside on lon...
