3D Chiral Self‐Assembling Matrixes for Regulating Polarization of Macrophages and Enhance Repair of Myocardial Infarction

open access: yesAdvanced Science, 2023
The regulation of inflammatory response at the site of injury and macrophage immunotherapy is critical for tissue repair. Chiral self‐assemblies are one of the most ubiquitous life cues, which is closely related to biological functions, life processes ...

Parameterization of Direct and Doorway Processes in R-Matrix Formalism [PDF]

open access: yesEPJ Web of Conferences, 2023
R-matrix formalism is extended beyond compound nuclear (CN) resonant reactions to include parameterization of direct as well as doorway processes. Direct processes in the R-matrix exterior are parameterized by a unitary matrix that introduces mixing ...

Generalizations of the R-Matrix Method to the Treatment of the Interaction of Short-Pulse Electromagnetic Radiation with Atoms

open access: yes, 2022
Since its initial development in the 1970s by Phil Burke and his collaborators, the R-matrix theory and associated computer codes have become the method of choice for the calculation of accurate data for general electron–atom/ion/molecule collision

R matrix for generalized quantum group of type A [PDF]

open access: yesJournal of Algebra, 2021
The generalized quantum group $\mathcal{U}(ε)$ of type $A$ is an affine analogue of quantum group associated to a general linear Lie superalgebra $\mathfrak{gl}_{M|N}$. We prove that there exists a unique $R$ matrix on tensor product of fundamental type representations of $\mathcal{U}(ε)$ for arbitrary parameter sequence $ε$ corresponding to a non ...

Relativistic B-Spline R-Matrix Calculations for Electron Collisions with Ytterbium

open access: yes, 2021
We have applied the full-relativistic Dirac B-Spline R-matrix method to obtain cross sections for electron scattering from ytterbium atoms. The results are compared with those obtained from a semi-relativistic (Breit-Pauli) model-potential approach and ...

What a Classical r-Matrix Really Is [PDF]

open access: yesJournal of Nonlinear Mathematical Physics, 1999
The notion of classical $r$-matrix is re-examined, and a definition suitable to differential (-difference) Lie algebras, -- where the standard definitions are shown to be deficient, -- is proposed, the notion of an ${\mathcal O}$-operator. This notion has all the natural properties one would expect form it, but lacks those which are artifacts of finite-

Angiopoietin-4-dependent venous maturation and fluid drainage in the peripheral retina

open access: yeseLife, 2018
The maintenance of fluid homeostasis is necessary for function of the neural retina; however, little is known about the significance of potential fluid management mechanisms.

Universal R-matrix and functional relations [PDF]

open access: yesReviews in Mathematical Physics, 2014
We collect and systematize general definitions and facts on the application of quantum groups to the construction of functional relations in the theory of integrable systems. As an example, we reconsider the case of the quantum group [Formula: see text] related to the six-vertex model.

Randomized Matrix Decompositions Using R

open access: yesJournal of Statistical Software, 2019
Matrix decompositions are fundamental tools in the area of applied mathematics, statistical computing, and machine learning. In particular, low-rank matrix decompositions are vital, and widely used for data analysis, dimensionality reduction, and data ...
