Dynamic Speckle
In physics, dynamic speckle is a result of the temporal evolution of a speckle pattern where variations in the scattering elements responsible for the formation of the interference pattern in the static situation produce the changes that are seen in the speckle pattern, where its grains change their intensity (grey level) as well as their shape along time. One easy to observe example is milk: place some milk in a teaspoon and observe the surface in direct sunlight. There will be a visible "dancing" pattern of coloured points. Where the milk dries on the spoon at the edge, the speckle is seen to be static. This is direct evidence of the thermal motion of atoms, which cause the Brownian motion of the colloidal particles in the milk, which in turn results in the dynamic speckle visible to the naked eye. Information content The dynamic pattern shows then the changes that, if they are analyzed along time, represent the activity of the illuminated material. The visual effect is tha ...

Speckle Imaging
Speckle imaging describes a range of high-resolution astronomical imaging techniques based on the analysis of large numbers of short exposures that freeze the variation of atmospheric turbulence. They can be divided into the shift-and-add ("''image stacking''") method and the speckle interferometry methods. These techniques can dramatically increase the resolution of ground-based telescopes, but are limited to bright targets. Explanation The principle of all the techniques is to take very short exposure images of astronomical targets, and then process those so as to remove the effects of astronomical seeing. Use of these techniques led to a number of discoveries, including thousands of binary stars that would otherwise appear as a single star to a visual observer working with a similar-sized telescope, and the first images of sunspot-like phenomena on other stars. Many of the techniques remain in wide use today, notably when imaging relatively bright targets. The resolution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Speckle Noise
Speckle, speckle pattern, or speckle noise is a granular noise texture degrading the quality as a consequence of interference among wavefronts in coherent imaging systems, such as radar, synthetic aperture radar (SAR), medical ultrasound and optical coherence tomography. Speckle is not external noise; rather, it is an inherent fluctuation in diffuse reflections, because the scatterers are not identical for each cell, and the coherent illumination wave is highly sensitive to small variations in phase changes. Although scientists have investigated this phenomenon since the time of Newton, speckles have come into prominence since the invention of the laser. Such reflections may occur on materials such as paper, white paint, rough surfaces, or in media with a large number of scattering particles in space, such as airborne dust or in cloudy liquids. They have been used in a variety of applications in microscopy, imaging, and optical manipulation. The vast majority of surfaces, synt ...

Speckle Tracking Echocardiography
In the fields of cardiology and medical imaging, speckle tracking echocardiography (STE) is an echocardiographic imaging technique. It analyzes the motion of tissues in the heart by using the naturally occurring speckle pattern in the myocardium (or motion of blood when imaged by ultrasound). This method of documentation of myocardial motion is a noninvasive method of definition for both vectors and velocity. When compared to other technologies seeking noninvasive definition of ischemia, speckle tracking seems a valuable endeavor. The speckle pattern is a mixture of interference patterns and natural acoustic reflections. These reflections are also described as ''speckles'' or ''markers''. The pattern being random, each region of the myocardium has a unique speckle pattern (also called ''patterns'', ''features'', or ''fingerprints'') that allows the region to be tracked. The speckle pattern is relatively stable, at least from one frame to the next.Bohs LN, Trahey GE. A novel met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Speckles
The cell nucleus (pl. nuclei; from Latin or , meaning ''kernel'' or ''seed'') is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm; and the nuclear matrix, a network within the nucleus that adds mechanical support. The cell nucleus contains nearly all of the cell's genome. Nuclear DNA is often organized into multiple chromosomes – long stands of DNA dotted with various proteins, such as histones, that protect and organize the DNA. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interchromatin Granule Clusters
An interchromatin granule is a cluster in the nucleus of a mammal cell which is enriched in pre-mRNA splicing factors. Interchromatin granules are located in the interchromatin regions of the mammalian Cell nuclei. They usually appear as irregularly shaped structures that vary in size and number. They can be observed by immunofluorescence microscopy. Interchromatin granules are structures undergoing constant change, and their components exchange continuously with the nucleoplasm, active transcription sites and other nuclear locations. Research on dynamics of interchromatin granules has provided new insight into the functional organisation of the nucleus and gene expression. Interchromatin granule clusters vary in size anywhere between one and several micrometers in diameter. They are composed of 20–25 nm granules that are connected in a beaded chain fashion appearance by thin fibrils. Interchromatin granule clusters (IGCs) have been proposed to be stockpiles of fully matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pillow Pal
Pillow Pals were a line of plush toys made by Ty, Inc. during the 1990s. The toys were given their name because they were soft like a pillow, and were made with children in mind. Though many of them resembled certain Beanie Babies, those that did not share names with their Beanie Baby counterparts. Such Pillow Pals saw a decline in popularity in the late 1990s with the introduction of Beanie Buddies, which were also larger versions of various Beanie Babies. In January 1999, all Pillow Pals were redesigned, and their colors were changed. This line did not sell well, and was discontinued by Ty around the end of the year. Today, PillowPals LLC takes children's drawings and replicates them into 3D pillows. At the time of the final retirement, Ty donated its remaining stock of pillow pals to the Ronald McDonald House Ronald McDonald House Charities (RMHC) is an independent American nonprofit organization whose stated mission is to create, find, and support programs that directly i ...

Speckle Frew
''The Books of Abarat'' are a series of young adult fantasy novels written and illustrated by English writer and visual artist Clive Barker. The series is intended to contain five books, three of which have been published from 2002 to 2011. The series takes place on the Abarat, a fictional archipelago consisting of twenty-five islands, one for each hour of the day (and one extra). Series The series is intended to consist of five books: * '' Abarat'' (2002) * ''Days of Magic, Nights of War'' (2004) * '' Absolute Midnight'' (2011) * ''Kry Rising'' (forthcoming; tentatively titled) * ''Until The End of Time'' (forthcoming; tentatively titled) History Barker began painting illustrations for the first book in the series, ''Abarat'', in 1995. He had originally intended for these paintings to be used in a 25-story "Book of Hours". As the number of paintings increased and the plot idea expanded, he decided the series would require four books (later increased to five) to fully contain ...
