Additive mappings on symmetric matrices
Linear Algebra and its Applications, 2006 Let \(F_1\) and \(F_2\) be two fields and let \(S_n(F_1)\) and \(S_n(F_2)\) be the set of symmetric matrices over \(F_1\) and \(F_2\), respectively. A mapping \(\Phi: S_n(F_1)\to S_n(F_2)\) is called additive if \(\Phi(A+B)=\Phi(A)+\Phi(B)\). It is said that \(\Phi\) doesn't increase rank-one if \(rk(\Phi(A))\leq1\) whenever \(rk(A)=1\). \textit{M.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

On orthogonally additive functions with big graph [PDF]
, 2017 Let E be a separable real inner product space of dimension at least 2 and V be a metrizable and separable linear topological space. We show that the set of all orthogonally additive functions mapping E into V and having big graphs is dense in the space ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

An Engel condition with an additive mapping in semiprime rings
, 2017 The main purpose of this paper is to prove the following result: Let n > 1 be a fixed integer, let R be a n!-torsion free semiprime ring, and let f : R -> R be an additive mapping satisfying the relation [f (x), x]n = [[. . . [[f (x), x], x], . . .], x] =

Journal of Child Language Acquisition and Development, 2020 By investigating Dutch children’s interpretation habitual and deontic conditionals, this paper explores their mapping of the concepts of hypotheticality and conditionality into a corresponding linguistic form of IF-conditionals.

Author Correction: Recent increases in tropical cyclone intensification rates
Nature Communications, 2019 The original version of this Article contained an error in the second sentence of the first paragraph of the ‘Quantile mapping’ section of the Methods, which incorrectly read ‘We primarily focus on results produced using an additive version of QDM26 by ...

Generalized stability of multi-additive mappings
Applied Mathematics Letters, 2010 Let \(V\) be a commutative semigroup, \(W\) a Banach space and \(n \geq 1\) an integer. A function \(f : V^n \to W\) is said to be multi-additive if \(f\) is additive in each variable. In this paper, the author studies the generalized stability of the multi-additive mappings using the direct method.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
