From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

First Eigenvalues of Some Operators Under the Backward Ricci Flow on Bianchi Classes

Mathematics
Let λ(t) be the first eigenvalue of the operator −∆+aRb on locally three-dimensional homogeneous manifolds along the backward Ricci flow, where a,b are real constants and R is the scalar curvature.

The p-Laplacian operator in oscillating thin domains

, 2018
In this paper we study the asymptotic behavior of the solutions of a class of nonlinear elliptic problems posed in a 2-dimensional domain that degenerates into a line segment (a thin domain) when a positive parameter $\varepsilon$ goes to zero. We also allow high oscillating behavior on the upper boundary of the thin domain as $\varepsilon \to 0 ...

A Graph‐Based Generative Artificial Intelligence Methodology for Autocorrection of Utility‐System P&IDs

Chemie Ingenieur Technik, EarlyView.
This work explores generative AI for automated revision of Piping and Instrumentation Diagrams (P&IDs). We frame P&ID correction as a translation problem, converting attributed P&ID graphs into sequences and learning revisions with a transformer‐based model.

Multiple homoclinic solutions for p-Laplacian Hamiltonian systems with concave–convex nonlinearities

Boundary Value Problems, 2020
The multiplicity of homoclinic solutions is obtained for a class of the p-Laplacian Hamiltonian systems d d t ( | u ˙ ( t ) | p − 2 u ˙ ( t ) ) − a ( t ) | u ( t ) | p − 2 u ( t ) + ∇ W ( t , u ( t ) ) = 0 $\frac{d}{dt}(|\dot{u}(t)|^{p-2}\dot{u}(t))-a(t)|

Revisiting Fisher's n‐D statistical vision: From algebraic abstraction to modern visualization

Canadian Journal of Statistics, EarlyView.
Abstract We revisit early foundational results in mathematical statistics derived by Ronald A. Fisher. They involve sampling distributions of statistics calculated from independent and identically distributed Normal observations, namely the root mean square deviation; the mean absolute deviation, conditional on already knowing the value of the root ...

Some bifurcation results for a class of $p$-Laplacian like operators

Differential and Integral Equations, 1997
Let us consider the boundary value problem \[ \begin{aligned} -\operatorname {div} \big (A(|\nabla u|)\nabla u\big)&=g\big (|x|,u,\lambda \big)\text{ in }\Omega ,\\ u&=0\text{ on }\partial \Omega , \end{aligned} \tag{1} \] where \(\Omega =B(0,R)\), \(R>0\) is the ball of radius \(R\) in \(\mathbb R^N\) and \(A\), \(g\) are continuous functions ...
