Additive maps preserving the scrambling index are bijective
, 2018 We prove that additive transformations on matrices over the binary Boolean semiring that preserve the scrambling index are automatically bijective. As a consequence we characterize such maps for matrices over an arbitrary antinegative semiring with ...

APPROXIMATION OF CAUCHY ADDITIVE MAPPINGS [PDF]
Bulletin of the Korean Mathematical Society, 2007 In this paper, we prove that a function satisfying the following inequality ‖ f(x) + 2f(y) + 2f(z) ‖ ≤ ‖ 2f( 2 + y + z) ‖+ 2(‖ x ‖ · ‖ y ‖ · ‖ z ‖) for all x, y, z ∈ X and for 2 ≥ 0, is Cauchy additive. Moreover, we will investigate for the stability in Banach spaces.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Multivariate Adaptive Regression Splines Enhance Genomic Prediction of Non-Additive Traits
AgronomyThe present work used Multivariate Adaptive Regression Splines (MARS) for genomic prediction and to study the non-additive fraction present in a trait. To this end, 12 scenarios for an F2 population were simulated by combining three levels of broad-sense

Zero-product preserving additive maps on symmetric operator spaces and self-adjoint operator spaces
, 2005 In this note, we characterize the additive maps on the space of symmetric operators and the space of self-adjoint operators which preserve zero-products in both directions, and the additive maps on the space of self-adjoint operators which preserve ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Additive rank-one nonincreasing maps on Hermitian matrices over the field GF(4)
, 2009 A complete classification of additive rank–one nonincreasing maps on hermitian matrices over Galois field GF(22) is obtained. This field is special and was not covered in a previouspaper. As a consequence, some known applications, like the classification

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
