T2-mapping increase is the prevalent imaging biomarker of myocardial involvement in active COVID-19: a Cardiovascular Magnetic Resonance study

Journal of Cardiovascular Magnetic Resonance, 2021
Background Early detection of myocardial involvement can be relevant in coronavirus disease 2019 (COVID-19) patients to timely target symptomatic treatment and decrease the occurrence of the cardiac sequelae of the infection. The aim of the present study

Association mapping and validation of QTLs for flour yield in the soft winter wheat variety Kitahonami. [PDF]

PLoS ONE, 2014
The winter wheat variety Kitahonami shows a superior flour yield in comparison to other Japanese soft wheat varieties. To map the quantitative trait loci (QTL) associated with this trait, association mapping was performed using a panel of lines from ...

Extreme positive linear maps between Jordan Banach algebras [PDF]

Bulletin of the Australian Mathematical Society, 1987
Let A and B be unital JB-algebras. We study the extremal structure of the convex set S (A,B) of all identity preserving positive linear maps from A to B. We show that every unital Jordan homomorphism from A to B is an extreme point of S (A,B). An extreme point of S (A,B) need not be a homomorphism and we show that, given A, every extreme point of S (A ...

Approximation theorems using the method of $\mathcal{I}_{2}$-statistical convergence

Journal of Amasya University the Institute of Sciences and Technology
In this study, we utilize the concept of $\mathcal{I}$-statistical convergence for double sequences to establish a general approximation theorem of Korovkin-type for double sequences of positive linear operators $(PLOs)$ mapping from $H_{\omega }\left( X\

A Grüss inequality for n-positive linear maps

Linear Algebra and its Applications, 2010
Let $\mathscr{A}$ be a unital $C^*$-algebra and let $ : \mathscr{A} \to {\mathbb B}({\mathscr H})$ be a unital $n$-positive linear map between $C^*$-algebras for some $n \geq 3$. We show that $$\| (AB)- (A) (B)\| \leq (A,||\cdot||)\, (B,||\cdot||)$$ for all operators $A, B \in \mathscr{A}$, where $ (C,\|\cdot\|)$ denotes the operator norm ...
