Weak and Strong Superiorization: Between Feasibility-Seeking and Minimization [PDF]

arXiv, 2014
We review the superiorization methodology, which can be thought of, in some cases, as lying between feasibility-seeking and constrained minimization. It is not quite trying to solve the full fledged constrained minimization problem; rather, the task is to find a feasible point which is superior (with respect to an objective function value) to one ...

Exploring amyotrophic lateral sclerosis through the visual system: A systematic review

European Journal of Neurology, Volume 31, Issue 12, December 2024.
Abstract Background and Purpose The human visual system relies on neural networks throughout the brain that are easily accessible for tests exploring eye structures and movements. Over the past two decades, investigations have been carried out on both afferent and efferent components of the visual system in people with amyotrophic lateral sclerosis ...

Functional connectome of brainstem nuclei involved in autonomic, limbic, pain and sensory processing in living humans from 7 Tesla resting state fMRI

NeuroImage, 2022
Despite remarkable advances in mapping the functional connectivity of the cortex, the functional connectivity of subcortical regions is understudied in living humans.

Problem Structures in the Theory and Practice of Superiorization [PDF]

arXiv, 2019
The purpose of this short paper is to identify the mathematical essence of the superiorization methodology. This methodology has been developed in recent years while attempting to solve specific application-oriented problems. Consequently, superiorization is often presented using the terminology of such problems.

Superiorization vs. Accelerated Convex Optimization: The Superiorized/Regularized Least-Squares Case [PDF]

arXiv, 2019
We conduct a study and comparison of superiorization and optimization approaches for the reconstruction problem of superiorized/regularized least-squares solutions of underdetermined linear equations with nonnegativity variable bounds. Regarding superiorization, the state of the art is examined for this problem class, and a novel approach is proposed ...

Superiorization: The asymmetric roles of feasibility-seeking and objective function reduction [PDF]

arXiv, 2022
The superiorization methodology can be thought of as lying conceptually between feasibility-seeking and constrained minimization. It is not trying to solve the full-fledged constrained minimization problem composed from the modeling constraints and the chosen objective function.

A (sub)field guide to quality control in hippocampal subfield segmentation on high‐resolution T2‐weighted MRI

Human Brain Mapping, Volume 45, Issue 15, October 15, 2024.
Illustration of the quality control (QC) process and investigator‐guided decision making for data quality. Green checkmarks indicate passed QC, while red cross marks indicate failed QC. Abstract Inquiries into properties of brain structure and function have progressed due to developments in magnetic resonance imaging (MRI).

Delving into the significance of the His289Tyr single-nucleotide polymorphism in the glutamate ionotropic receptor kainate-1 (Grik1) gene of a genetically audiogenic seizure model

Frontiers in Molecular Neuroscience
Genetic abnormalities affecting glutamate receptors are central to excitatory overload-driven neuronal mechanisms that culminate in seizures, making them pivotal targets in epilepsy research.

Tectal etiology for irrepressible saccades: a case study in a Rhesus monkey [v1; ref status: indexed, http://f1000r.es/we]

F1000Research, 2013
Brain circuits controlling eye movements are widely distributed and complex. The etiology of irrepressible square wave saccades is not fully understood and is likely different for different neuropathologies.

Direct Monitoring of Whole‐Brain Electrodynamics via High‐Spatiotemporal‐Resolution Photoacoustics with Voltage‐Sensitive Dye

Laser &Photonics Reviews, Volume 18, Issue 10, October 2024.
This work proposes a novel method for monitoring deep‐brain electrodynamics with a voltage‐sensitive dye (VSD)‐based photoacoustic imaging platform, called PA‐VSD. This platform is demonstrated to allow for effectively localizing epileptic foci and visualizing voltage conduction pathways in a high spatiotemporal resolution. Abstract Brain voltage plays
