Blind deconvolution under band limitation [PDF]

open access: yes, 2003
A blind deconvolution method is developed on conditions: a point spread function is band-limited, both an object and a PSF are nonnegative, and output is a diffraction-limited object.

An effective variational model for simultaneous reconstruction and segmentation of blurred images

open access: yesJournal of Algorithms & Computational Technology, 2016
The segmentation of blurred images is of great importance. There have been several recent pieces of work to tackle this problem and to link the areas of image segmentation and image deconvolution in the case where the blur function κ is known or of known

Time‐Resolved Multi‐Omics Identify Biomarkers of Immediate Reactions to mRNA Vaccination

open access: yesAllergy, EarlyView.
We compared early vaccine‐induced immune and metabolic signatures and downstream immunity after second and booster BNT162b2 doses in participants with sARs, ISSRs, or no reactions. Neutrophil mobilization, antiviral programs, and robust anti‐S‐antibody responses occurred across reaction groups.

Richardson–Lucy Iterative Blind Deconvolution with Gaussian Total Variation Constraints for Space Extended Object Images

open access: yesPhotonics
In ground-based astronomical observations or artificial space target detections, images obtained from a ground-based telescope are severely distorted due to atmospheric turbulence. The distortion can be partially compensated by employing adaptive optics (

A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Non-parametric PSF estimation from celestial transit solar images using blind deconvolution

open access: yesJournal of Space Weather and Space Climate, 2016
Context: Characterization of instrumental effects in astronomical imaging is important in order to extract accurate physical information from the observations.

FDX1 Depletion Activates CD8+ T Cell Antitumor Immunity by Promoting DMBT1 Secretion in Cuproptosis of Colorectal Cancer

open access: yesCancer Science, EarlyView.
Elesclomol‐induced cuproptosis potently activates both innate and adaptive antitumor immunity, especially CD8+ T cell immunity. FDX1 serves as a central regulator of CD8+ T cell functionality through DMBT1 downregulation during cuproptosis in colorectal cancer.
