Practical Implementation of Log-Scale Active Illumination Microscopy [PDF]

open access: yes, 2010
Active illumination microscopy (AIM) is a method of redistributing dynamic range in a scanning microscope using real-time feedback to control illumination power on a sub-pixel time scale.

Differences in illumination estimation in #thedress [PDF]

open access: yes, 2017
We investigated whether people who report different colors for #thedress do so because they have different assumptions about the illumination in #thedress scene.

Imaging through noise with quantum illumination [PDF]

open access: yesScience Advances, 2019
Full-field imaging using quantum illumination distinguishes the true image from a structured thermal background. The contrast of an image can be degraded by the presence of background light and sensor noise.

Electron magnetotransport in GaAs/AlGaAs superlattices with weak and strong inter-well coupling

open access: yes, 2007
We report on magnetotransport measurements in two MBE-grown GaAs/AlGaAs superlattices formed by wide and narrow quantum wells and thin Si-doped barriers subject to tilted magnetic fields.

Comparative analysis of aperture averaging & receiver diversity schemes in FSO channel performance under high scintillation regime

open access: yesDiscover Electronics
High Scintillation is a major problematic issue for Free Space Optical Communication (FSOC) system. Consequently, in this case, the Single Input & Single Output (SISO) optical channel performance has been degraded.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

A mathematical morphology based approach for vehicle detection in road tunnels [PDF]

open access: yes, 2011
A novel approach to automatically detect vehicles in road tunnels is presented in this paper. Non-uniform and poor illumination conditions prevail in road tunnels making difficult to achieve robust vehicle detection.

High-resolution transport-of-intensity quantitative phase microscopy with annular illumination [PDF]

open access: yesScientific Reports, 2017
For quantitative phase imaging (QPI) based on transport-of-intensity equation (TIE), partially coherent illumination provides speckle-free imaging, compatibility with brightfield microscopy, and transverse resolution beyond coherent diffraction limit ...
