Granulomatosis with polyangiitis: Common and uncommon presentations

open access: yesJournal of Medical Imaging and Radiation Oncology, Volume 66, Issue 8, Page 1089-1096, December 2022., 2022
Summary Granulomatosis with polyangiitis (GPA) is a multisystemic autoimmune small vessel vasculitis predominantly affecting the respiratory and renal systems. Other systems such as the central nervous system, orbital, cardiac and gastrointestinal systems may also be involved to a lesser degree.

BrainCog: A Spiking Neural Network based Brain-inspired Cognitive Intelligence Engine for Brain-inspired AI and Brain Simulation [PDF]

open access: yes, 2022
Spiking neural networks (SNNs) have attracted extensive attentions in Brain-inspired Artificial Intelligence and computational neuroscience. They can be used to simulate biological information processing in the brain at multiple scales. More importantly, SNNs serve as an appropriate level of abstraction to bring inspirations from brain and cognition to

Lifting-based variational multiclass segmentation algorithm: design, convergence analysis, and implementation with applications in medical imaging [PDF]

open access: yesarXiv, 2022
We propose, analyze and realize a variational multiclass segmentation scheme that partitions a given image into multiple regions exhibiting specific properties. Our method determines multiple functions that encode the segmentation regions by minimizing an energy functional combining information from different channels.

Pyogenic Brain Abscess Caused by Peptostreptococcus in a Patient with HIV-1 Infection

open access: yesDiseases, 2017
In the setting of HIV, cerebral lesions are usually secondary to lymphoma and opportunistic infections; however, in patients with CD4 counts above 200 cells/uL, other pathologies such as pyogenic brain abscess could gain importance.

Streptococcus constellatus Brain Abscess in a Middle-Aged Man With an Undiagnosed Patent Foramen Ovale [PDF]

open access: yes, 2023
Brain abscess is a rare diagnosis. Common sources of infection include direct spread from otic sources, sinuses, or oral cavities, and hematogenous spread from distant sources, including the heart and lungs. Brain abscess with cultures growing oral flora

A differentiable brain simulator bridging brain simulation and brain-inspired computing [PDF]

open access: yesarXiv, 2023
Brain simulation builds dynamical models to mimic the structure and functions of the brain, while brain-inspired computing (BIC) develops intelligent systems by learning from the structure and functions of the brain. The two fields are intertwined and should share a common programming framework to facilitate each other's development.
