Different Heterotrimeric G Protein Dynamics for Wide-Range Chemotaxis in Eukaryotic Cells
Chemotaxis describes directional motility along ambient chemical gradients and has important roles in human physiology and pathology. Typical chemotactic cells, such as neutrophils and Dictyostelium cells, can detect spatial differences in chemical ...

Robust Dynamic Range Computation for High Dynamic Range Content [PDF]
High dynamic range (HDR) imaging has become an important topic in both academic and industrial domains. Nevertheless, the concept of dynamic range (DR), which underpins HDR, and the way it is measured are still not clearly understood. The current approach to measure DR results in a poor correlation with perceptual scores (r ≈ 0.6).

Increasing ADC dynamic range in information-measuring systems by methods of digital signal processing [PDF]
The article deals with the method of increasing the dynamic range of a standard analog-to-digital converter. The method is based on interpolation of signal sections, which are limited in amplitude, using undistorted sections.

High Speed and High Dynamic Range Video with an Event Camera [PDF]
Event cameras are novel sensors that report brightness changes in the form of a stream of asynchronous “events” instead of intensity frames. They offer significant advantages with respect to conventional cameras: high temporal resolution, high dynamic ...

Adaptive dynamic range shift (ADRIFT) quantitative phase imaging [PDF]
Quantitative phase imaging (QPI) with its high-contrast images of optical phase delay (OPD) maps is often used for label-free single-cell analysis. Contrary to other imaging methods, sensitivity improvement has not been intensively explored because ...

Dynamic Range Expansion Using Cumulative Histogram Learning for High Dynamic Range Image Generation
In modern digital photographs, most images have low dynamic range (LDR) formats, which means that the range of light intensities from the darkest to the brightest is much lower than the range that can be perceived by the human eye.
