Orders of Perfect Groups with Dihedral Involution Centralizers
Let G be a finite group that is equal to its commutator subgroup, and suppose that G contains an element of order 2 whose centralizer in G is dihedral of 2-power order. We study the cases where this centralizer is dihedral of order 8, 16, 32, 64, 128, or 256. It is true in each case that this …

The involution principle and h-positive symmetric functions
The criterion of h-positivity corresponds to the criterion that a polynomial representation of the general linear group of V is a sum of tensor products of symmetric powers of V. Expanding the iterated exponential function as a power series yields coefficients whose positivity implies the …

Proteolysis of mammary secretion proteins during involution of bovine mammary gland
… period the mammary gland undergoes a process of involution. The profile of mammary secretion proteins changes throughout the dry period. Increased proteolytic activity and breakdown fragments of milk proteins contribute to the composition of mammary secretions during dry period. The objectives of …

cdh descent for homotopy Hermitian K-Theory of rings with involution
… of Hermitian vector bundles over a ring with involution with 2 invertible; this generalizes a result of Schlichting-Tripathi. We then prove a periodicity theorem for Hermitian K-theory and use it to construct an E-infinity motivic ring spectrum representing homotopy Hermitian K-theory. From …

996, moyu, and involution: tech work in the age of platform monopoly
Over the past decade, consumer internet companies such as Google, Facebook, Tencent, and Alibaba have come to symbolize a new era marked by dynamism, entrepreneurialism, and innovation. This has led us to believe that these internet companies play an outsized role in the creation of economic value …

Investigating Murine Uterine Tissue Dynamics: Biomechanical and Histological Perspectives on Postpartum Involution and Scar-Induced Remodeling
… between uterine scar integrity, postpartum involution, and the biomechanics of uterine tissue is a crucial step toward predicting the risk of uterine rupture during future labor events. This project aims to utilize ex-vivo mechanical testing and noninvasive imaging techniques to investigate …

AGE-RELATED GUT DYSBIOSIS ACCELERATES THYMIC INVOLUTION AND ALTERS PERIPHERAL T CELL REPERTOIRE IN DUCHENNE MUSCULAR DYSTROPHY
Emerging researches highlight a significant interplay between the immune system and skeletal muscle, particularly in the context of inflammatory muscle disorders and dystrophic conditions like Duchenne Muscular Dystrophy (DMD), as well as during the natural process of muscle regeneration. …

Preventing Thymus Involution In K5.Cyclin D1 Transgenic Mice Sustains The Naïve T Cell Compartment With Age
… restricted naive T cells. However, thymus involution during the aging process reduces naïve T cell output, leading to defective immune responsiveness to newly encountered antigens. We have found that early thymus involution precipitates the age-associated shift favoring memory T cell …

Gene Set Analysis of Post-Lactational Mammary Gland Involution Gene Signatures In Inflammatory and Triple Negative Breast Cancer
… that tissue remodeling during post-lactational involution period mimics wound healing and tumorigenesis like pathological conditions. This indicates that post-lactational involution may create the microenvironment that initiates the development of precancerous mammary cells and promotes the …

Effects of Thymus Size and Involution On The Contribution of Recent Thymic Emigrants to The Peripheral T Cell Pool
… and due to severe viral infections. Thymus involution results in decreased thymopoiesis and RTE output leading to a reduced diversity of peripheral T cells. This increases susceptibility to disease and impairs immune responsiveness to vaccines. Therefore, studies aimed at maintaining or …

Finite groups with a special 2-generator property, and order of centralizers in finite groups
… if for every 1 $\not=$ x $\in$ G, either x is an involution and G = $\langle$x,y$\rangle$ for some y $\in$ G or x is not an involution and there is an involution z $\in$ G with G = $\langle$x,z$\rangle$. We show that ""most"" of the simple groups of Lie type do not lie in $\Gamma\sb1\sp{(2)}$, we …

The functorial semantics of Lie theory
… To accomplish this, we develop the theory of involution algebroids, which are a tangent-categorical sketch of Lie algebroids. We show that the category of Lie algebroids is precisely the category of involution algebroids in smooth manifolds, and that the category of Weil algebras is precisely …

Purification of Calmodulin and Quantification of Its Levels in Mammary Tissue and Isolated Cells During Pregnancy and Lactation (Acini, Secretory, Myoepithelial)
… level during lactation, then, after the onset of involution, decreased to values similar to those measured from tissue of pregnant rats. When tissue from 15 animals in different stages of pregnancy, lactation and involution were compared, the RIA gave 2.6-fold higher results than the PDE assay. …

Integral Representations of Positive Linear Functionals
… linear functionals on commutative algebras with involution and semigroups with involution. We prove Bochner and Plancherel type theorems for representations of positive functionals and show that, under some conditions, the Bochner and Plancherel representations are equivalent. We also consider …

Weil Representations of Unitary Groups

Morphologie and Pathologie des menschlichen Thymus im Alter und bei Myasthenia gravis: eine morphometrische Studie
Der Thymus unterliegt einer altersabhängigen Involution. Dieses Phämomen soll in dieser Arbeit mit morphometrischen Mitteln untersucht werden. Mit Hilfe der Farbdifferenzanalyse wird der Anteil von Thymusgewebe im mediastinalen Fettgewebe festgestellt. Weiterhin wird die Veränderung des Thymus bei …

Characterization of Non-Coding RNAs in Regulating Thymic Epithelial Cell Responses to Pathophysiological Stress

Development and Maintenance of Thymic Epithelial Microenvironment
… microenvironment, however, undergoes age related involution, Resulting in a reduction of the repertoire of T-‐cells that are produced, and a decreased Capacity to respond to new antigen. Even though significant thymic epithelial turnover occurs, it is unclear if postnatal thymic progenitors/stem …
