Pseudo-differential operators with symbols in modulation spaces

open access: yes, 2010
We establish continuity results for pseudo-differential operators with symbols in modulation spaces, especially for spaces related to classical Wiener amalgam spaces.

Spectral Theory of Dirac Operators with Measures [PDF]

open access: yes, 2023
Dirac operators with measures are the extension of the classical Dirac operators. We give a compatible interpretation of such a Dirac differential equation with a measure coefficient and discuss the general direct spectral theory of this kind of ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

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.

On subclasses of analytic functions based on a quantum symmetric conformable differential operator with application

open access: yesAdvances in Difference Equations, 2020
Quantum calculus (the calculus without limit) appeared for the first time in fluid mechanics, noncommutative geometry and combinatorics studies. Recently, it has been included into the field of geometric function theory to extend differential operators ...

An inverse nodal problem for integro-differential operators

open access: yes, 2011
The inverse nodal problem of recovering integral-differential operators with the Sturm–Liouville differential part and the integral part of Volterra type is studied. We reconstruct the potential and the boundary conditions provided the kernel of integral

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Multilinear analysis for discrete and periodic pseudo-differential operators in Lp-spaces

open access: yesRevista Integración, 2018
In this note we announce our investigation on the Lp properties for periodic and discrete multilinear pseudo-differential operators. First, we review the periodic analysis of multilinear pseudo-differential operators by showing classical multilinear ...

Gelfand-Shilov spaces, pseudo-differential operators and localization operators

open access: yes, 2006
We present new results concerning pseudo-differential operators in the function spaces $S^{\mu}_{\nu}(\R^n)$ of Gelfand and Shilov. In particular we discuss $S^{\mu}_{\nu}(\R^n)$-regularity of solutions to SG-elliptic pseudo-differential equations ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
