Multivariate modality inference using Gaussian kernel [PDF]

open access: yes, 2014
The number of modes (also known as modality) of a kernel density estimator (KDE) draws lots of interests and is important in practice. In this paper, we develop an inference framework on the modality of a KDE under multivariate setting using Gaussian ...

Breaking Boundaries: Chronic Diseases and the Frontiers of Immune Microenvironments

open access: yesMed Research, Volume 1, Issue 1, Page 62-102, June 2025.
ABSTRACT The immune microenvironment includes immune cells, cytokines, extracellular matrix, vesicles, etc. The interactions between these components form a unique local immune microecology. Although immunity serves as the defense against external pathogens, aberrant immune activation often contributes to disease development.
