Occurrence of erythema multiforme following COVID-19 vaccination: a review.
Clin Exp Vaccine Res
April 2023
The fast development of vaccines against the novel coronavirus disease is among the most critical steps taken to control this potentially fatal viral disease. Like other vaccines, the coronavirus disease 2019 (COVID-19) vaccines can also cause unwanted reactions. Erythema multiforme (EM) is among the oral mucocutaneous side effects of COVID-19 vaccines.

- Alzheimer's disease (AD) affects brain connectivity, specifically reducing synchronization in certain areas like the medial temporal and frontal regions.
- A study compared 15 mild AD patients with 15 healthy controls, measuring brain activity through EEG over one year, revealing no overall change in synchronization.
- However, patients with rapidly progressing AD showed significant decreases in synchronization, particularly in the left frontotemporal cortex, suggesting EEG synchronization might serve as a cost-effective biomarker for monitoring AD progression.
Network community-detection enhancement by proper weighting.
Phys Rev E Stat Nonlin Soft Matter Phys
April 2011
In this paper, we show how proper assignment of weights to the edges of a complex network can enhance the detection of communities and how it can circumvent the resolution limit and the extreme degeneracy problems associated with modularity. Our general weighting scheme takes advantage of graph theoretic measures and it introduces two heuristics for tuning its parameters. We use this weighting as a preprocessing step for the greedy modularity optimization algorithm of Newman to improve its performance.
