Postnatal Involution and Counter-Involution of the Thymus [PDF]

Frontiers in Immunology, 2020
Thymus involution occurs in all vertebrates. It is thought to impact on immune responses in the aged, and in other clinical circumstances such as bone marrow transplantation. Determinants of thymus growth and size are beginning to be identified.

Lattices with involution [PDF]

Transactions of the American Mathematical Society, 1958
Introduction. By a "lattice with involution," or "i-lattice," we shall mean a lattice L together with an involution [1, p. 4] xx' in L. A distributive ilattice in which xnx'

Involution: Inverting the Inherence of Convolution for Visual Recognition [PDF]

Computer Vision and Pattern Recognition, 2021
Convolution has been the core ingredient of modern neural networks, triggering the surge of deep learning in vision. In this work, we rethink the inherent principles of standard convolution for vision tasks, specifically spatial-agnostic and channel ...

Age‐related thymic involution: Mechanisms and functional impact

Aging Cell, 2022
The thymus is the primary immune organ responsible for generating self‐tolerant and immunocompetent T cells. However, the thymus gradually involutes during early life resulting in declined naïve T‐cell production, a process known as age‐related thymic ...

Does Involution Cause Anxiety? An Empirical Study from Chinese Universities

International Journal of Environmental Research and Public Health, 2022
The debate over whether involution causes anxiety has persisted because no studies have attempted to quantify introversion and study its relationship to anxiety.

The Transformation of Parents’ Perception of Education Involution Under the Background of “Double Reduction” Policy: The Mediating Role of Education Anxiety and Perception of Education Equity

Frontiers in Psychology, 2022
The “Double Reduction” policy in China was introduced to reduce the academic burden of primary and secondary school students, ease their parents’ education anxiety, enhance education equity, and curb the phenomenon of education involution.

Quaternion involutions and anti-involutions [PDF]

Computers & Mathematics with Applications, 2007
AbstractAn involution or anti-involution is a self-inverse linear mapping. In this paper we study quaternion involutions and anti-involutions. We review formal axioms for such involutions and anti-involutions. We present two mappings, one a quaternion involution and one an anti-involution, and a geometric interpretation of each as reflections.

Study on the Pattern of Postpartum Uterine Involution in Dairy Cows

Animals, 2023
Postpartum uterine involution is necessary for the normal reproduction of dairy cows. The study aimed to investigate the pattern of postpartum uterine involution and the impact of parity on uterine involution in Chinese Holstein dairy cows.

Single-cell transcriptomics reveals involution mimicry during the specification of the basal breast cancer subtype.

Cell Reports, 2021
Basal breast cancer is associated with younger age, early relapse, and a high mortality rate. Here, we use unbiased droplet-based single-cell RNA sequencing (RNA-seq) to elucidate the cellular basis of tumor progression during the specification of the ...
