Nonlocal Mechanical Metamaterials Enabling Soliton Mode Conversion

open access: yesSmall Structures, Volume 6, Issue 12, December 2025.
A mechanical metamaterial (MM) system with nonlocal interactions is presented, where elastic (nontopological) solitons encountering a boundary defect undergo mode conversion and generate backward‐propagating topological solitons. This finding reveals a new mechanism for soliton dynamics in nonlocal systems, offering insights into energy transport, wave

Well-posedness, a short survey

open access: yes, 2007
In this paper we analyze the property of Tykhonov wellposedness in relation to other well-posedness properties which are ordinal and, as stated in the title, we give a survey on some important results on well-posedness in scalar optimization and in scalar inequalities.

Well-posedness for a coagulation multiple-fragmentation equation

open access: yes, 2014
We consider a coagulation multiple-fragmentation equation, which describes the concentration $c\_t(x)$ of particles of mass $x \in (0,\infty)$ at the instant $t \geq 0$ in a model where fragmentation and coalescence phenomena occur.

DeepGEM‐EGF: A Bayesian Strategy for Joint Estimates of Source‐Time Functions and Empirical Green's Functions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract An earthquake record is the convolution of source radiation, path propagation and site effects, and instrument response. Isolating the source component requires solving an ill‐posed inverse problem. Whether the instability of inferred source parameters arises from varying properties of the source, or from approximations we introduce in solving

Well-Posedness for a Class of Strongly Mixed Variational-Hemivariational Inequalities with Perturbations

open access: yesJournal of Applied Mathematics, 2012
The concept of well-posedness for a minimization problem is extended to develop the concept of well-posedness for a class of strongly mixed variational-hemivariational inequalities with perturbations which includes as a special case the class of ...

Constraining 2D Hydrogeological Inversion With 3D Lithological Data

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract In hydrogeology, piezometric data are the key constraints for model calibration. Their limits for three‐dimensional (3D) parameterization have often been pointed out, with water heads commonly regarded as having too little sensitivity to vertical heterogeneity.
