Global higher integrability for parabolic quasiminimizers in metric spaces [PDF]

open access: yes, 2013
We prove higher integrability up to the boundary for minimal p-weak upper gradients of parabolic quasiminimizers in metric measure spaces, related to the heat equation.

Symmetrically coupled higher-order nonlinear Schroedinger equations: singularity analysis and integrability

open access: yes, 2000
The integrability of a system of two symmetrically coupled higher-order nonlinear Schr\"{o}dinger equations with parameter coefficients is tested by means of the singularity analysis.

Higher Derivations on Finitely Generated Integral Domains. II [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
In this paper, we prove the following theorem: Let A = k [ x 1 , ⋯ , x t ] A = k[{x_1}, \cdots ,{x_t}] be a finitely generated integral domain over a field k of characteristic ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Regularity Results for Local Minimizers of Functionals with Discontinuous Coefficients

open access: yesBruno Pini Mathematical Analysis Seminar, 2016
We give an overview on recent regularity results of local vectorial minimizers of under two main features: the energy density is uniformly convex with respect to the gradient variable only at infinity and it depends on the spatial variable through a ...

On the Weyl Tensor Classification in All Dimensions and its Relation with Integrability Properties

open access: yes, 2013
In this paper the Weyl tensor is used to define operators that act on the space of forms. These operators are shown to have interesting properties and are used to classify the Weyl tensor, the well known Petrov classification emerging as a special case ...

Higher integrability for vector-valued parabolic quasi-minimizers on metric measure spaces

open access: yes, 2016
We establish local higher integrability estimates for upper gradients of vector-valued parabolic quasi-minimizers in metric measure spaces, satisfying a doubling property and supporting a weak Poincaré inequality.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Formal First Integrals of General Dynamical Systems

open access: yesAdvances in Mathematical Physics, 2016
The goal of this paper is trying to make a complete study on the integrability for general analytic nonlinear systems by first integrals. We will firstly give an exhaustive discussion on analytic planar systems. Then a class of higher dimensional systems

Asymptotic four point functions

open access: yesJournal of High Energy Physics, 2019
We initiate the study of four-point functions of large BPS operators at any value of the coupling. We do it by casting it as a sum over exchange of superconformal primaries and computing the structure constants using integrability.
