A new image deconvolution method with fractional regularisation
Journal of Algorithms & Computational Technology, 2016 Image deconvolution is an important pre-processing step in image analysis which may be combined with denoising, also an important image restoration technique, and prepares the image to facilitate diagnosis in the case of medical images and further ...

Blind Deconvolution Using Modulated Inputs [PDF]
IEEE Transactions on Signal Processing, 2020 This paper considers the blind deconvolution of multiple modulated signals, and an arbitrary filter. Multiple inputs $\boldsymbol{s}_1, \boldsymbol{s}_2, \ldots, \boldsymbol{s}_N =: [\boldsymbol{s}_n]$ are modulated (pointwise multiplied) with random sign sequences $\boldsymbol{r}_1, \boldsymbol{r}_2, \ldots, \boldsymbol{r}_N =: [\boldsymbol{r}_n ...

Animal Models and Experimental Medicine, EarlyView.Two closely related BALB/c substrains exhibit different early responses to adriamycin (ADR)‐induced nephropathy. BALB/cByJcl mice showed lower baseline WT1‐positive nuclei counts and NPHS1 immunoreactivity than BALB/cAJcl mice, together with extracellular matrix and integrin programs that were enriched at baseline and persisted at Day 5.

Demultiplexing in mode-division multiplexing system using multichannel blind deconvolution
IEEE Photonics Journal, 2016 We propose a mode demultiplexing method based on multichannel blind deconvolution (MBD) for a mode-division multiplexing (MDM) system. A 6 $\times$ 6 MDM transmission system is simulated to verify the performance of MBD.

Application of RSSD-OCYCBD Strategy in Enhanced Fault Detection of Rolling Bearing
Complexity, 2020 The defect characteristics of rolling bearing are difficult to excavate at the incipient injury phase; in order to effectively solve this issue, an original strategy fusing recursive singular spectrum decomposition (RSSD) with optimized cyclostationary ...

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation
Angewandte Chemie International Edition, EarlyView.Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.
