Decisions Under Radical Uncertainty: The Role of Volitional Liminality in Radical Innovation

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Radical innovation management can be understood as an organizational practice that enacts distant futures, which are open‐ended and unknowable. Such radical innovation endeavors are thus characterized by radical uncertainty, where possible futures are not only quantitatively but qualitatively different from the present, and ...

Phase-Field Approach for Faceted Solidification

, 2003
We extend the phase-field approach to model the solidification of faceted materials. Our approach consists of using an approximate gamma-plot with rounded cusps that can approach arbitrarily closely the true gamma-plot with sharp cusps that correspond to

Automation and Augmentation in Theological Perspective

Modern Theology, EarlyView.
Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

Finite element discretization of parabolic‐elliptic interface problems [PDF]

PAMM, 2007
AbstractWe consider mixed boundary value problems for partial differential equations which are parabolic in one part of the underlying domain and elliptic in another part. Such problems arise in eddy current simulations in electromagnetics. A fully discrete scheme for the numerical solution of such problems is presented.

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

A numerical comparison between degenerate parabolic and quasilinear hyperbolic models of cell movements under chemotaxis [PDF]

, 2014
We consider two models which were both designed to describe the movement of eukaryotic cells responding to chemical signals. Besides a common standard parabolic equation for the diffusion of a chemoattractant, like chemokines or growth factors, the two ...

Short-time height distribution in 1d KPZ equation: starting from a parabola

, 2016
We study the probability distribution $\mathcal{P}(H,t,L)$ of the surface height $h(x=0,t)=H$ in the Kardar-Parisi-Zhang (KPZ) equation in $1+1$ dimension when starting from a parabolic interface, $h(x,t=0)=x^2/L$. The limits of $L\to\infty$ and $L\to 0$

A Direct Method for Modeling and Simulations of Elliptic and Parabolic Interface Problems

, 2021
Interface problems have many applications in fluid dynamics, molecular biology, electromagnetism, material science, heat distribution in engines, and hyperthermia treatment of cancer. Mathematically, interface problems commonly lead to partial differential equations (PDE) whose in- put data are discontinuous or singular across the interfaces in the ...

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

Development of Interfaces in Nonlinear Multidimensional Reaction-Diffusion Equations With Parabolic p-Laplacian Properties

Journal of Applied Mathematics
This research examines the behavior of interfaces in nonlinear multidimensional reaction–diffusion equations with parabolic p-Laplacian properties, which are applicable across a wide range of biological, physical, and chemical contexts. The value of this
