Unsupervised image blind super resolution via real degradation feature learning

IET Computer Vision
In recent years, many methods for image super‐resolution (SR) have relied on pairs of low‐resolution (LR) and high‐resolution (HR) images for training, where the degradation process is predefined by bicubic downsampling.

A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions

Advanced Materials, EarlyView.
It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...

Degradation-Oriented Adaptive Network for Blind Super-Resolution

, 2022
Most of the super-resolution methods based on deep neural networks use a fixed image degradation model. However, when the real image degradation is inconsistent with the model assumptions, the performance of the network will be severely reduced. To address this issue, we propose a degradation-oriented adaptive network (DOANet), which can be used to ...

Synchronized Ablation of Multifocal Tumors Enabled by Multi‐Channel Lanthanide Nanocomposites

Advanced Materials, EarlyView.
A multi‐channel lanthanide nanocomposite enables orthogonal monitoring of tumor pH, glutathione, and temperature to guide customized therapy. Real‐time luminescence readouts determine a single irradiation protocol that synchronizes drug release and photothermal treatment, allowing efficient ablation of multifocal tumors while minimizing overtreatment ...

Overview of techniques applicable to self-interference incoherent digital holography [PDF]

Journal of the European Optical Society-Rapid Publications, 2013
Self-interference incoherent digital holography (SIDH) retrieves the complex hologram from the object illuminated by the incoherent light. Supported by the adaptive optic feature, SIDH is readily applicable to the ocular imaging to investigate the human ...

Federated Learning for Blind Image Super-Resolution

Traditional blind image SR methods need to model real-world degradations precisely. Consequently, current research struggles with this dilemma by assuming idealized degradations, which leads to limited applicability to actual user data. Moreover, the ideal scenario - training models on data from the targeted user base - presents significant privacy ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.
