Counter-Examples to the Concentration-Cancellation Property

, 2008
International audienceWe study the existence and the asymptotic behavior of large amplitude high-frequency oscillating waves subjected to the 2D Burger equation. This program is achieved by developing tools related to supercritical WKB analysis.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

Advanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments

Journal of Field Robotics, EarlyView.
ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel

Soft Interferometric Nanostrain Sensor Reveals Solid‐Liquid Interfacial Tension Oscillation Amplified by Competitive Adsorption

Small, EarlyView.
An interferometric nanostrain sensor is developed to investigate unlabeled protein adsorption by directly measuring real‐time interfacial tensions at unprecedented resolution (<0.25 mN m−1). A high‐frequency, low‐amplitude oscillation of the interfacial tension is found to be superimposed over the Langmuir adsorption.

Linking Density and Nanoscale Crystallinity to Hydration in Nafion PEMFC Membranes: Insights From Experiment and Molecular Dynamics Simulations

Small Structures, EarlyView.
Molecular dynamics and experimental analysis show that higher crystallinity in Nafion enhances molecular packing, thereby increasing effective density. A proposed model bridges experimental and molecular‐scale observations by quantitatively linking water uptake to density variations, offering a predictive framework for optimising hydration and ...

Time‐Domain Computation of Propagation Characteristics of Partial Discharge in Cross‐Linked Polyethylene High‐Voltage Cable Incorporating Modified Frequency‐Dependent Parameters

High Voltage, EarlyView.
ABSTRACT The propagation characteristics of partial discharge (PD) in cables impact PD detection sensitivity, defect localisation accuracy and defect severity evaluation. Currently, the effects of semiconducting materials' frequency‐dependent properties and corrugated aluminium sheath structures on PD signal propagation in high‐voltage (HV) cables ...

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Large-time asymptotic behavior of the infinite system of harmonic oscillators

, 2016
The mixed initial-boundary value problem for infinite one-dimensional chain of harmonic oscillators on the half-line is considered. We study the large time behavior of solutions and derive the dispersive bounds.

The Impact of Risk Exposure and Environmental Conditions on European Banking Efficiency

European Financial Management, EarlyView.
ABSTRACT This study investigates the determinants of bank cost efficiency in Europe by applying a dynamic Bayesian stochastic frontier approach. We distinguish between two conceptually and empirically separate components of efficiency: (1) an intrinsic component, driven by internal bank features such as size and risk exposure, and (2) an extrThis study
