Multilevel Unbalanced Graph Partitioning with Applications to Graph Drawing
, 2007 在資訊科學研究中，圖形切割問題廣泛出現在多種領域內，其中也包括圖形繪製。在圖形繪製中，一個好的呈現在於是否將各節點間的相互關係表現出來。而區分的方式便是利用圖形切割演算法。 在本篇論文中，我們提出一個與過去不同的切割方法，先在樹上做切割，再對應到圖形上，藉以區分不同群集，進行一連串調整的動作找出最佳解，而最後利用force-directed placement的方法將圖形繪製出來。 過去在找尋k-partition的方法，最典型的是將原圖切割成兩份，再將其中一份切成兩份，以此類推，最後再稍作調整 ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Solution Techniques for Fuzzy Graph Partitioning Based on Heuristic Optimization [PDF]
Control and Optimization in Applied MathematicsIn this study, we proposed a novel graph partitioning problem where the edges are characterized by trapezoidal fuzzy numbers. A linear ranking function is employed to establish an order among these fuzzy numbers.

Finding planted partitions in random graphs with general degree distributions [PDF]
, 2009 We consider the problem of recovering a planted partition such as a coloring, a small bisection, or a large cut in an (apart from that) random graph. In the last 30 years many algorithms for this problem have been developed that work provably well on ...

Neurologic Manifestations of Long COVID Affect Adult Females More Severely Than Males
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To characterize differences in neurologic manifestations of postacute sequelae of SARS‐CoV‐2 infection (Neuro‐PASC) between females and males. Methods Cross‐sectional study of the first consecutive 261 posthospitalization Neuro‐PASC (PNP) and 2068 nonhospitalized Neuro‐PASC (NNP) patients evaluated at the Neuro‐COVID clinic between ...

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...
