An Efficient and Unified Modeling Framework for Trickle Bed Reactors: A Modular Approach
Chemie Ingenieur Technik, EarlyView.This review gives an insight in modeling and designing techniques for multiphase catalytic reactors and their associated limitations and potential improvements. To enhance the predictive capabilities and capture events that take place on different scales, a modular approach is proposed.

Review: Hydrocodes for Structural Response to Underwater Explosions
Shock and Vibration, 1999 The applicability of the various hydrocode methodologies (Lagrangian, Eulerian, Coupled Eulerian–Lagrangian, and Arbitrary Lagrangian–Eulerian) for structural response to underwater explosions is reviewed.

Communications on Pure and Applied Mathematics, EarlyView.Abstract We address the problem of regularity of solutions ui(t,x1,…,xN)$u^i(t, x^1, \ldots, x^N)$ to a family of semilinear parabolic systems of N$N$ equations, which describe closed‐loop equilibria of some N$N$‐player differential games with Lagrangian having quadratic behaviour in the velocity variable, running costs fi(x)$f^i(x)$ and final costs gi(

Randomly sparsified Richardson iteration: A dimension‐independent sparse linear solver
Communications on Pure and Applied Mathematics, EarlyView.Abstract Recently, a class of algorithms combining classical fixed‐point iterations with repeated random sparsification of approximate solution vectors has been successfully applied to eigenproblems with matrices as large as 10108×10108$10^{108} \times 10^{108}$. So far, a complete mathematical explanation for this success has proven elusive.

Lagrangian vector field and Lagrangian formulation of partial differential equations
Condensed Matter Physics, 2005 In this paper we consider the Lagrangian formulation of a system of second order quasilinear partial differential equations. Specifically we construct a Lagrangian vector field such that the flows of the vector field satisfy the original system of ...

Accurate Calculation of Electron Paramagnetic Resonance Parameters for Molybdenum Compounds
ChemPhysChem, EarlyView.Using a curated database of experimentally characterized, biologically relevant Mo(V) compounds, this study evaluates the optimal choice of basis sets, density functionals, and wavefunction methods for accurately computing g‐tensor values and 95Mo hyperfine coupling constants, with the goal of establishing reliable protocols for predicting electron ...

Deep Underground Science and Engineering, EarlyView.In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...
