A Review on Homogeneity across Hydrological Regions [PDF]
Open Access Journal of Biogeneric Science and Research, 2021 Hydrologic classification is the method of scientifically arranging streams, rivers or catchments into groups with the most similarity of flow regime features and use it to recognize hydrologically homogenous areas. Previous homogeneous attempts were depended on overabundance of hydrologic metrics that considers features of variability of flows that ...

Regional homogeneity changes in patients with Parkinson's disease [PDF]
Human Brain Mapping, 2008 AbstractResting state brain activity in Parkinson's disease (PD) can give clues to the pathophysiology of the disorder, and might be helpful in diagnosis, but it has never been explored using functional MRI (fMRI). In the current study, we used a regional homogeneity (ReHo) method to investigate PD‐related modulations of neural activity in the resting ...

Multiple sclerosis impairs regional functional connectivity in the cerebellum
NeuroImage: Clinical, 2014 Resting-state functional magnetic resonance imaging (rs-fMRI) has been used to study changes in long-range functional brain connectivity in multiple sclerosis (MS). Yet little is known about how MS affects functional brain connectivity at the local level.

Disrupted Regional Homogeneity in Drug-Naive Patients With Bipolar Disorder
Frontiers in Psychiatry, 2020 ObjectiveStudies on alterations in the regional neural activity in the brain of patients with bipolar disorder (BD) have provided conflicting results because of different medications used and study designs.

Assessing the Probability of Drought Severity in a Homogeneous Region [PDF]
Complexity, 2022 The standardized precipitation index (SPI) is one of the most widely used indices for characterizing and monitoring drought in various regions. SPI's applicability has regional and time‐scale constraints when it observes in several homogeneous climatic regions with similar characteristics.

Changes of resting cerebral activities in subacute ischemic stroke patients
Neural Regeneration Research, 2015 This study aimed to detect the difference in resting cerebral activities between ischemic stroke patients and healthy participants, define the abnormal site, and provide new evidence for pathological mechanisms, clinical diagnosis, prognosis prediction ...

Frequency specificity of regional homogeneity in the resting-state human brain. [PDF]
PLoS ONE, 2014 Resting state-fMRI studies have found that the inter-areal correlations in cortical networks concentrate within ultra-low frequencies (0.01-0.04 Hz) while long-distance connections within subcortical networks distribute over a wider frequency range (0.01-
