Solving parametric radical equations with depth 2 rigorously using the restriction set method [PDF]
arXiv, 2020 We review the history and previous literature on radical equations and present the rigorous solution theory for radical equations of depth 2, continuing a previous study of radical equations of depth 1. Radical equations of depth 2 are equations where the unknown variable appears under at least one square root and where two steps are needed to ...

FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Topological radicals, III. Joint spectral radius [PDF]
arXiv, 2012 We develop the theory of topological radicals, and in particular the theory of the hypocompact radical. The results are applied for obtaining convenient formulas of calculation of the joint spectral radius of a precompact family of elements in a Banach algebra.

The Radical-Pair Mechanism of Magnetoreception.
Annual Review of Biophysics, 2016 Although it has been known for almost half a century that migratory birds can detect the direction of the Earth's magnetic field, the primary sensory mechanism behind this remarkable feat is still unclear.

Radicals in the class of compact right topological rings
Applied General Topology, 2014 We construct in this article three radicals in the class of compact right topological rings. We prove also that a simple left Noetherian compact right topological ring is finite.

FEBS Letters, EarlyView.Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Characterizing τ-rigid-finite algebras with radical square zero [PDF]
arXiv, 2014 In this paper, we give a characterization of tau-rigid-finite algebras with radical square zero in terms of the separated quivers, which is an analog of a famous characterization of representation-finite algebras with radical square zero.

Proceedings of the National Academy of Sciences of the United States of America, 1981 During primate evolution, a major factor in lengthening life-span and decreasing age-specific cancer rates may have been improved protective mechanisms against oxygen radicals.

Everyday Radicalism and the Democratic Imagination: Dissensus, Rebellion and Utopia
Politics and Governance, 2018 The prevalence of social injustice suggests the need for radical transformation of political economy and governance. This article develops the concept of ‘everyday radicalism’, which positions the everyday as a potential site of social change.

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...
