Computational Mechanics Model to Evaluate the Structural Maintenance of Catenated Hydrogen‐Bonded Organic Frameworks

open access: yesSmall, EarlyView.
This study presents a computational framework treating crystalline HOFs as adaptive atomic‐scale interfaces. Catenated HOFs preserve lattice stability under load while enabling auxetic deformation and reversible nonlinearity. The results provide direct evidence that supramolecular interactions govern macroscopic resilience and structural adaptability ...

Fractional Poisson process

Communications in Nonlinear Science and Numerical Simulation, 2003
The author elaborates a fractional Poisson distribution based on the fractional generalization of the Kolmogorov-Feller equation. The relationship between the developed fractional model and the standard Poisson random process is discussed.

Fractional Poisson process (II)☆

Chaos, Solitons & Fractals, 2006
Let \(H\in(1/2,1) \). For \(t>0\) the process \[ W_{H}(t) =\frac{1}{(H-1/2)} \int_{0}^{t} u^{1/2-H} \biggl(\int_{u}^{t}\tau ^{H- 1/2}(\tau-u)^{H-3/2}\,d\tau \biggr)\, dq(u) \] is called a fractional Poisson process, where \(q(u) =N(u)/\sqrt{\lambda }-\sqrt{\lambda }u\), and \(N(u)\) is a homogeneous Poisson process with the intensity \(\lambda >0 ...
