Blind Estimation Versus Direct Measurement of the Arterial Input Function in Dynamic Contrast‐Enhanced MRI of the Breast

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1947-1955, October 2026.
PurposeAccurate arterial input functions (AIFs) are essential for quantitative dynamic contrast‐enhanced (DCE) MRI, yet direct measurement is challenging and population‐averaged AIFs neglect patient‐specific variability. Blind deconvolution provides an alternative by estimating patient‐specific AIFs directly from tissue data, up to a scale factor. This

Perinatal lead (Pb) exposure and alterations to amyloid beta and metabolic profiles in the brain

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Developmental neurotoxicant exposures (e.g., lead [Pb]) are suspected contributors to dementia. Dementia is characterized by amyloid beta (Aβ) plaques and dysregulated metabolism. To better understand the relationship between environment and dementia risk, we assessed the impact of perinatal Pb exposure on dementia‐related ...

Blind Deconvolution With Nonlocal Similarity and l(0) Sparsity for Noisy Image

, 2016
The blind image deconvolution techniques with sparsity prior in gradient domain are sensitive to noise, even a small amount of noise. To address this problem, in this letter, we propose a novel blind deconvolution model that combines low-rank property ...

Image Deblurring and Effect of Wiener, Regularized, Lucky-Richardson, Blind-Deconvolution, Average and Median Filters on Blurred Image and Noisy Image

Tikrit Journal of Engineering Sciences, 2014
In image deblurring, we try to recover the original, sharp image by using a mathematical model of the blurring process. There are several techniques to recover the original image, but they could not recover the image exactly.

Unraveling Microporosity in Hard Carbons: Insights Into Sustainable Sodium‐Ion Battery Materials

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Hidden microporosity in hard‐carbon anodes for sodium‐ion batteries is revealed by small‐angle X‐ray scattering combined with Ruland–Smarsly analysis, including closed pores inaccessible to gas adsorption. Comparing petroleum‐derived and biowaste‐derived carbons links nanoscale disorder, surface area, and pore architecture to sodium storage ...

LINEAR DISCRETE CONVOLUTION AND ITS INVERSE. PART 2. DECONVOLUTION [PDF]

We present here several ways for calculating the linear discrete convolution and its inverse - the deconvolution, by direct methods, generator functions, Z-transform, using matrices and MATLAB.

Blind deconvolution

, 1988
Considering a signal X which is a process of random varia­bles identically independently distributed, and the signal Y obtained by filtering X through a linear system s, we study the estimation of s from the observation of Y in the follo­wing semi-parametric situation : the law of X is unknown and non Gaussian, and s has an inverse of convolution with ...

Dynamic Granulocyte Turnover Inferred From cfDNA Methylation Predicts Immunotherapy Benefit in Liver‐Metastatic Small Cell Lung Cancer: A Prospective Biomarker Study

MedComm, Volume 7, Issue 9, September 2026.
This prospective study evaluated envafolimab plus chemotherapy in 29 SCLC patients with liver metastases, integrating multi‐omics analyses (WES, RNA‐seq, DNA methylation, ctDNA, and cfDNA methylation). The research framework encompassed granulocyte turnover dynamics, prognostic risk modeling, molecular mechanism exploration across risk strata, and ...

Long‐Term Prognosis and Immunotranscriptomic Landscape in Esophageal Squamous Cell Carcinoma With Different Pathological Responses to Neoadjuvant Chemoradiotherapy: A Retrospective Cohort Study

MedComm – Oncology, Volume 5, Issue 3, September 2026.
This study comprehensively characterizes the long‐term prognosis and immunotranscriptomic landscape associated with different tumor regression grades (TRGs) in esophageal squamous cell carcinoma (ESCC) following neoadjuvant chemoradiotherapy. By integrating bulk RNA‐seq, single‐cell transcriptomics, and multiplexed immunohistochemistry, we demonstrate ...
