On the Rings of Differential Operators [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2006
The rings of differential operators have been studied by many mathematicians like Musson [5], Smith and Stafford [7]. Jones in [2] and [3] introduced new ideas for such kind of rings and he found a new line.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Differential symmetry operators first order canonical differential equations

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. Symmetries play an important role in mechanics and theoretical physics. The main models in these sciences are differential equations and systems of equations.

Note on a role for entire functions of the classes P and P*

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
We use the B and B* operators of Levin on the Classes P and P* and a comparison principle to prove a Gauss-Lucas Theorem for differential operators. The connection with the determination of final sets for differential operators is then clarified.

Symmetric Conformable Fractional Derivative of Complex Variables

open access: yesMathematics, 2020
It is well known that the conformable and the symmetric differential operators have formulas in terms of the first derivative. In this document, we combine the two definitions to get the symmetric conformable derivative operator (SCDO).

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

An Interpretation of the Geometric Meaning of the Finite Difference and the Function Derivative through the Use of the Finite Element Method Tools

open access: yesМеханика машин, механизмов и материалов, 2016
In the present article on the basis of earlier formulated planspatial problem of the finite elements method the concept of finite differences for the twodimensional continuous environment is developed.

Commutativity and spectral properties of genuine Baskakov-Durrmeyer type operators and their \(k\)th order Kantorovich modification

open access: yesJournal of Numerical Analysis and Approximation Theory, 2015
In this paper we present an overview of commutativity results and different methods for the proofs for  Baskakov-Durrmeyer type operators and associated differential operators.

Degenerate Differential Operators with Parameters

open access: yesAbstract and Applied Analysis, 2007
The nonlocal boundary value problems for regular degenerate differential-operator equations with the parameter are studied. The principal parts of the appropriate generated differential operators are non-self-adjoint.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
