A scalable clustering algorithm to approximate graph cuts

Authors Suchan L, Li H, Munk A Journal Arxiv Citation arXiv:2308.09613. Abstract Due to its computational complexity, graph cuts for cluster detection and identification are used mostly in the form of convex relaxations. We propose to utilize the original graph cuts such as Ratio, Normalized or Cheeger Cut in order

Aggregation and beyond: alpha-synuclein-based biomarkers in synucleinopathies

Authors Chopra A, Outeiro TF Journal Brain Citation Brain. 2023 Aug 1:awad260. Abstract Parkinson’s disease is clinically known for the loss of dopaminergic neurons in the substantia nigra pars compacta and accumulation of intraneuronal cytoplasmic inclusions rich in alpha-synuclein called ‚Lewy bodies‘ and ‚Lewy neurites‘. Together with dementia with Lewy
