Identifiability and Sloppiness of Structured Systems with a Matrix Fraction Description Using Finite Frequency Responses

Identifiability and Parameter Estimation Difficulty of Structured Systems with Matrix Fraction Description Based on Finite Frequency Responses Background In scientific research and engineering applications, parameter identification is a core task for understanding and controlling complex systems. Whether in power systems, mechanical systems, or che...

Topological Features of Brain Functional Networks Are Reorganized During Chronic Tinnitus: A Graph-Theoretical Study

Reorganization of Topological Features in Brain Functional Networks in Patients with Chronic Tinnitus Academic Background Tinnitus is the perception of sound in the absence of any external acoustic stimuli or internal sources of auditory perception, with a global prevalence ranging from 11.9% to 30.3%. Patients with tinnitus experience not only aud...

Cortical Morphological Networks Differ Between Gyri and Sulci

Differences in Brain Cortical Morphological Networks Between Gyri and Sulci Introduction The human brain, as an interconnected complex network, can be mapped through virtual imaging using multimodal magnetic resonance imaging (MRI) technology. By analyzing this network using graph theory methods, many studies have discovered some non-trivial topolo...

Analysis of Reading-Task-Based Brain Connectivity in Dyslexic Children Using EEG Signals

Brain Connectivity Analysis Based on Reading Tasks in Children with Dyslexia (Using EEG Signals) Dyslexia is a neurodevelopmental disorder that affects the normal reading ability, even though children with normal intelligence may still be affected. This paper investigates the differences in brain connectivity between children with dyslexia and norm...

Functional Connectivity Alterations in Patients with Post-Stroke Epilepsy Based on Source-Level EEG and Graph Theory

Research Report on Changes in Functional Connectivity in Post-Stroke Epilepsy (PSE) Patients Based on Source-Level EEG and Graph Theory Research Background Epilepsy has various etiologies, including idiopathic, congenital, head trauma, central nervous system infections, brain tumors, neurodegenerative diseases, and cerebrovascular diseases. Among t...
