Weakly Tripotent Elements in Quaternion Rings over ℤp [PDF]

ITM Web of Conferences
Let R be a ring. An element x ∈ R is weakly tripotent if x can be written as x3 = x or x3 = −x. In this paper, we discuss weakly tripotency in quaternion rings over ℤp, ℍ/ℤp. We also give some conditions for the element x ∈ ℍ/ℤp to be weakly tripotent.

Thymflammation: The Role of a Constitutively Active Inflammatory Network and "Ectopic" Cell Types in the Thymus in the Induction of T Cell Tolerance and Beyond. [PDF]

Immunol Rev
ABSTRACT The thymus exhibits constitutive activation of nearly all major inflammatory pathways, including sterile MyD88‐dependent signaling and interferon production by mTECs, the presence of cellular and molecular components of type 1, type 2, and type 3 responses, as well as sustained B cell activation. The reasons for the existence of such a complex

Capture of Totipotency in Mouse Embryonic Stem Cells in the Absence of Pdzk1. [PDF]

Adv Sci (Weinh)
This work provides a new strategy to capture totipotency in ESCs by deletion of Pdzk1. Pdzk1‐null ESCs can integrate to fetus, placenta, and yolk sac tissues easily in chimera experiment, and also can self‐organize to form blastocyst‐like structures efficiently. The developmental potentials of Pdzk1‐KO ESCs are mainly through up‐regulating some lineage

Finite tripotents and finite JBW⁎-triples [PDF]

Journal of Mathematical Analysis and Applications, 2020
We study two natural preorders on the set of tripotents in a JB$^*$-triple defined in terms of their Peirce decomposition and weaker than the standard partial order. We further introduce and investigate the notion of finiteness for tripotents in JBW$^*$-triples which is a natural generalization of finiteness for projections in von Neumann algebras.

Representation of tripotents and representations via tripotents

Linear Algebra and its Applications, 2011
An element A in an algebra \(\mathcal A\) is called tripotent if \(A^3=A\). The authors discuss various questions related to this concept. For instance, if \(A\) and \(B\) are tripotent, under what conditions are \(A+B\) and \(AB\) tripotent?

Role of glycosphingolipid SSEA‐3 and FGF2 in the stemness and lineage commitment of multilineage differentiating stress enduring (MUSE) cells

Cell Proliferation, Volume 56, Issue 1, January 2023., 2023
We demonstrated that SSEA‐3, a glycosphingolipid (GSL), may act as an FGF‐2 co‐receptor in MUSE cell, this activates the FGF2 signalling cascade mainly through PI3K mediation. Our study is one of the first evidence attributing GSL a functional role in governing stem cell biology. (A) Experimental plan. (B) Effect of cultivation of MUSE cells with SSEA3

Indirect Mechanisms of Transcription Factor‐Mediated Gene Regulation during Cell Fate Changes

Advanced Genetics, Volume 3, Issue 4, December 2022., 2022
Transcription factors (TFs) control cellular identity and changes in TF combinations and/or levels can trigger a cell fate change. Insight into mechanisms through which TFs reprogram cellular identity is consequently the key to understanding various physiological and pathological transitions.

Tripotent elements in quaternion rings over ℤ_p [PDF]

Acta Universitatis Sapientiae, Mathematica, 2021
Abstract In this paper, we discuss tripotent1 elements in the finite ring ℍ/ℤp. We provide examples and establish conditions for tripotency. We follow similar methods used in [3] for idempotent elements in ℍ/ℤp.

Inverse Eigenvalue Problem and Least‐Squares Problem for Skew‐Hermitian {P,K + 1}‐Reflexive Matrices

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
This paper involves related inverse eigenvalue problem and least‐squares problem of skew‐Hermitian {P,k + 1}‐reflexive(antireflexive) matrices and their optimal approximation problems. The above problems are studied by converting them into two simpler cases: k = 1 and k = 2.
