Spatial resolution enhancement using deep learning improves chest disease diagnosis based on thick slice CT

npj Digital Medicine
CT is crucial for diagnosing chest diseases, with image quality affected by spatial resolution. Thick-slice CT remains prevalent in practice due to cost considerations, yet its coarse spatial resolution may hinder accurate diagnoses.

Impact of Deep Learning 3D CT Super-Resolution on AI-Based Pulmonary Nodule Characterization

Tomography
Background/Objectives: Correct pulmonary nodule volumetry and categorization is paramount for accurate diagnosis in lung cancer screening programs. CT scanners with slice thicknesses of multiple millimetres are still common worldwide, and slice thickness

Slice-by-slice and global smoothness of slice regular and polyanalytic functions

Annali di Matematica Pura ed Applicata (1923 -), 2022
The concept of slice regular function over the real algebra $\mathbb{H}$ of quaternions is a generalization of the notion of holomorphic function of a complex variable. Let $Ω$ be an open subset of $\mathbb{H}$, which intersects $\mathbb{R}$ and is invariant under rotations of $\mathbb{H}$ around $\mathbb{R}$.

Comprehensive Assessment of Arterial, Tissue, and Venous Collaterals for Evaluating the Infarct Growth Rate: The Multimodal Collateral Score

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

Slice by slice

, 2020
During the development and progression of coronary artery disease not only the large epicardial coronary arteries but also the more distal resistance vessels are affected. Studying the role of the entire coronary vasculature is a major challenge due to heart motion and the large vascular diameter range.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Management Closed Control Loop Automation for Improved RAN Slice Performance by Subslicing

IEEE Access
Network slicing applied to a radio access network (RAN) offers the potential to enhance the satisfaction of service requirements and optimize resource utilization, particularly in scenarios where radio resources are limited.

Slice Nondeterminism.

, 2023
This paper studies a technique for describing and formalising nondeterministic functions, using slice categories. Results of a nondeterministic function are modelled by an object of the slice category over the codomain of the function, which is an indexed family over the codomain.

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Categories with Slicing

Theory and Applications of Categories, 2009
The category of elements of a presheaf provides a functor from any presheaf category to the category \({\mathcal C}at\) of categories. This paper provides axiomatics for when a functor \(\partial :{\mathcal A}\rightarrow {\mathcal C}at\) is close to being, or actually being, equivalent to such a construction. Several categories of higher graphs arising
