Effect of benzocyclobutadieno-annelation on cyclic conjugation in perylene

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2011
Earlier studies showed that the intensity of cyclic conjugation in the central ring R of perylene can be significantly altered by means of benzo-annelation. In particular, linear (resp. angular) benzoannelation was found to decrease (resp.

ortho-Substituted 2-Phenyldihydroazulene Photoswitches: Enhancing the Lifetime of the Photoisomer by ortho-Aryl Interactions

open access: yesMolecules, 2021
Photochromic molecules are systems that undergo a photoisomerization to high-energy isomers and are attractive for the storage of solar energy in a closed-energy cycle, for example, in molecular solar thermal energy storage systems.

On Solvability Conditions for a Certain Conjugation Problem

open access: yesAxioms, 2021
We study a certain conjugation problem for a pair of elliptic pseudo-differential equations with homogeneous symbols inside and outside of a plane sector. The solution is sought in corresponding Sobolev–Slobodetskii spaces.

Linear time equivalence of Littlewood―Richardson coefficient symmetry maps [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Benkart, Sottile, and Stroomer have completely characterized by Knuth and dual Knuth equivalence a bijective proof of the Littlewood―Richardson coefficient conjugation symmetry, i.e. $c_{\mu, \nu}^{\lambda} =c_{\mu^t,\nu^t}^{\lambda ^t}$.

THE METHOD OF VARIATION OF ARBITRARY CONSTANTS IN THE CASE OF A SYSTEM OF LINEAR DIFFERENTIAL EQUATIONS OF DIFFERENT ORDERS

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
The paper considers structures consisting of rods connected in one node.Longitudinal and transverse vibrations of such a structure are described by systems of linear differential equations on star graphs.The noted system of equations consists of three ...

Click Conjugation of Boron Dipyrromethene (BODIPY) Fluorophores to EGFR-Targeting Linear and Cyclic Peptides

open access: yesMolecules, 2021
Through a simple 1,3-cycloaddition reaction, three BODIPY-peptide conjugates that target the extracellular domain of the epidermal growth factor receptor (EGFR) were prepared and their ability for binding to EGFR was investigated.

Model of Non-Isothermal Consolidation in the Presence of Geobarriers and the Total Approximation Properties of its Finite Element Solutions

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2023
The boundary value problem for the system of quasi-linear parabolic equations in the presence of integral conjugation conditions is considered. The boundary value problem is a mathematical model of the process of non-isothermal filtration consolidation ...

Windowed linear canonical transform: its relation to windowed Fourier transform and uncertainty principles

open access: yesJournal of Inequalities and Applications, 2022
The windowed linear canonical transform is a natural extension of the classical windowed Fourier transform using the linear canonical transform. In the current work, we first remind the reader about the relation between the windowed linear canonical ...
