Conservation Laws of Discrete Korteweg-de Vries Equation
Symmetry, Integrability and Geometry: Methods and Applications, 2005 All three-point and five-point conservation laws for the discrete Korteweg-de Vries equations are found. These conservation laws satisfy a functional equation, which we solve by reducing it to a system of partial differential equations.

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections
Advanced Electronic Materials, EarlyView.The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Nonlinear Dynamics and Invariants of Motion in ReRAM Cells
Advanced Electronic Materials, EarlyView.A second‐order cell, hosting one capacitor and two back‐to‐back ReRAMs, admits Invariants of Motion: its states lie on one‐dimensional manifolds at all times. The cell shows quiescent monostability or bistability, depending on the manifold index. At equilibrium, the capacitor voltage vanishes.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Rural Labor Supply and Economic Opportunities: Commuting, Migration, Tariffs, and Immigration
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Some rural counties remain dependent on agricultural or manufacturing jobs, but an increasing proportion have diversified economics. Rural counties also differ in their abilities to commute to an urban market characterized by higher wages and labor productivity.

Lumped modeling of bubbling fluidized beds for high‐temperature processes
AIChE Journal, EarlyView.Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

1. Dispersive/Dissipative Mechanisms for Conservation Laws
, 2008 . Several results about the stability of waves in systems of conservation/balance laws, disseminated in the litterature, obey to a common rule. The linear/spectral stability of the microscopic pattern (the internal structure of the wave) implies the well-

Experimental and numerical study of liquid–liquid systems using the Euler–Lagrange/VOF approach
AIChE Journal, EarlyView.Abstract Achieving stable liquid–liquid dispersions with controlled droplet size remains a challenge due to the complex interplay of dispersed phase viscosity, hydrodynamic conditions and interfacial interactions. This work presents a validated computational framework for droplet breakage and coalescence in liquid–liquid dispersions with variable ...

Evolution of Physical Intelligence Across Scales
Advanced Intelligent Discovery, EarlyView.By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.
