A Model for the Frequency Distribution of Multi-Scale Phenomena [PDF]

open access: yesInformation, 2020
Frequency analysis is often used to investigate the structure of systems representing multi-scale real-world phenomena. In many different environments, functional relationships characterized by a power law have been recognized, but, in many cases this simple model has turned out to be absolutely inadequate and other models have been proposed.

A Multi-Scale Computational Model of Excitotoxic Loss of Dopaminergic Cells in Parkinson's Disease

open access: yesFrontiers in Neuroinformatics, 2020
Parkinson's disease (PD) is a neurodegenerative disorder caused by loss of dopaminergic neurons in substantia nigra pars compacta (SNc). Although the exact cause of cell death is not clear, the hypothesis that metabolic deficiency is a key factor has ...

Knowledge Representation for Multi-Scale Physiology Route Modeling

open access: yesFrontiers in Neuroinformatics, 2021
We present a framework for the topological and semantic assembly of multiscale physiology route maps. The framework, called ApiNATOMY, consists of a knowledge representation (KR) model and a set of knowledge management (KM) tools.

Multi-scale Modeling of Trauma Injury [PDF]

open access: yes, 2006
We develop a multi-scale high fidelity biomechanical and physiologically-based modeling tools for trauma (ballistic/impact and blast) injury to brain, lung and spinal cord for resuscitation, treatment planning and design of personnel protection. Several approaches have been used to study blast and ballistic/impact injuries.

Multi-scale Multi-attention Network for Moiré Document Image Binarization

open access: yes, 2021
In this paper, we propose a Multi-scale Multi-attention Network (MsMa-Net) to binarize document images contaminated by moiré patterns from camera-captured screens.

Modelling of blood thrombosis at microscopic and mesoscopic scales

open access: yesComputer Assisted Methods in Engineering and Science, 2019
Blood coagulation at the place of the complete severing of a vessel or puncturing of a vessel sidewall is usually a beneficial reaction, as it protects the body from bleeding and maintains hemostasis, while the formation of a blood clot inside the blood

Multi-scale Modelling for Threshold Dependent Differentiation [PDF]

open access: yesMathematical Modelling of Natural Phenomena, 2009
The maintenance of a stable stem cell population in the epidermis is important for robust regeneration of the stratified epithelium. The population size is usually regulated by cell secreted extracellular signalling molecules as well as intracellular molecules.

Multi‐Scale Electrical Conductivity Model of the Contiguous United States

open access: yesGeophysical Research Letters
The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a

X-FASNet: cross-scale feature-aware with self-attention network for cognitive decline assessment in Alzheimer's disease

open access: yesFrontiers in Neurology
Early diagnosis of Alzheimer's disease is critical for effective therapeutic intervention. The progressive nature of cognitive decline requires precise computational methods to detect subtle neuroanatomical changes in prodromal stages.
