Gated Context Aggregation Network for Image Dehazing and Deraining [PDF]

open access: yesIEEE Workshop/Winter Conference on Applications of Computer Vision, 2018
Image dehazing aims to recover the uncorrupted content from a hazy image. Instead of leveraging traditional low-level or handcrafted image priors as the restoration constraints, e.g., dark channels and increased contrast, we propose an end-to-end gated ...

Generalizing Aggregation Functions in GNNs:High-Capacity GNNs via Nonlinear Neighborhood Aggregators [PDF]

open access: yesarXiv, 2022
Graph neural networks (GNNs) have achieved great success in many graph learning tasks. The main aspect powering existing GNNs is the multi-layer network architecture to learn the nonlinear graph representations for the specific learning tasks. The core operation in GNNs is message propagation in which each node updates its representation by aggregating

Unexpected cell type-dependent effects of autophagy on polyglutamine aggregation revealed by natural genetic variation in C. elegans. [PDF]

open access: yes, 2020
BACKGROUND: Monogenic protein aggregation diseases, in addition to cell selectivity, exhibit clinical variation in the age of onset and progression, driven in part by inter-individual genetic variation. While natural genetic variants may pinpoint plastic

Simulations of Oligomeric Intermediates in Prion Diseases [PDF]

open access: yes, 2003
We extend our previous stochastic cellular automata based model for areal aggregation of prion proteins on neuronal surfaces. The new anisotropic model allow us to simulate both strong beta-sheet and weaker attachment bonds between proteins. Constraining

To aggregate or not to aggregate – Is it a matter of the ribosome?

open access: yesBioEssays, 2023
AbstractNeurodegenerative syndromes present as proteinopathies – does ribosomal infidelity contribute to the protein toxicity that is the driving force for neuronal cell loss? Intracellular and extracellular protein aggregates overwhelm the clearance capacity of cells and tissues. Proteins aggregate when hydrophobic residues are exposed.

To aggregate or not to aggregate? A new role for p62 [PDF]

open access: yesEMBO reports, 2009
Cell signalling is carried out by selective and complex metabolic networks that, when impaired, result in disease. The challenge for the cell is to maintain fidelity during normal processes, while allowing the plasticity that is required to control the complicated machinery of a functional cell.

Microplastics and Nanoplastics in Aquatic Environments: Aggregation, Deposition, and Enhanced Contaminant Transport.

open access: yesEnvironmental Science and Technology, 2017
Plastic litter is widely acknowledged as a global environmental threat, and poor management and disposal lead to increasing levels in the environment. Of recent concern is the degradation of plastics from macro- to micro- and even to nanosized particles ...

Optimal aggregation algorithms for middleware [PDF]

open access: yesACM SIGACT-SIGMOD-SIGART Symposium on Principles of Database Systems, 2001
Assume that each object in a database has m grades, or scores, one for each of m attributes. For example, an object can have a color grade, that tells how red it is, and a shape grade, that tells how round it is.

Room-temperature phosphorescence from metal-free polymer-based materials

open access: yesCell Reports Physical Science, 2022
Summary: Room-temperature phosphorescence (RTP) has received extensive attention in recent years due to its various potential applications. Pure organic RTP materials may overcome the shortcomings of harsh preparation conditions and high toxicity ...
