Fuzzy clustering with Minkowski distance [PDF]
Distances in the well known fuzzy c-means algorithm of Bezdek (1973) are measured by the squared Euclidean distance.Other distances have been used as well in fuzzy clustering.

Weak log majorization and determinantal inequalities
, 2016 Denote by $ _n$ the set of $n\times n$ positive definite matrices. Let $D = D_1\oplus \dots \oplus D_k$, where $D_1\in _{n_1}, \dots, D_k \in _{n_k}$ with $n_1+\cdots + n_k=n$. Partition $C\in _n$ according to $(n_1, \dots, n_k)$ so that $\Diag C = C_1\oplus \dots \oplus C_k$. We prove the following weak log majorization result: \begin{equation*}

Neighborhood social environments and mental health among youth and adults in public housing
American Journal of Community Psychology, EarlyView.Abstract Neighborhoods influence health in part through social processes. However, little is known about how multiple neighborhood social processes co‐occur, or about within (vs. between) neighborhood variation in social processes and health. This study asked how residents of a large public housing development describe their neighborhood and used ...

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT We examined the relationship between adverse childhood experiences (ACEs) and epigenetic age acceleration (EAA) in adulthood as measured by second and third generation epigenetic clocks by performing a systematic review of the literature. The electronic databases MEDLINE and EMBASE were searched on 17 July 2023.

Australian Journal of Social Issues, EarlyView.ABSTRACT Over the last three decades, overseas researchers have utilised administrative data to identify distinct patterns in shelter use. In Australia, the use of administrative data to understand service utilisation patterns among people ‘at risk’ of homelessness and experiencing homelessness is limited.

Australian Journal of Social Issues, EarlyView.ABSTRACT Systems and structures designed to protect and support young people, specifically (in this paper) young women, are ironically the same systems that maintain gender disparity. Consequently, this has influenced the embodied identities of young women who experience and use violence. Such systemic and structural intersectionality has impacted upon
