A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Stability of a Fully Discrete Local Discontinuous Galerkin Method for the Generalized Benjamin–Ono Equation

Numerical Methods for Partial Differential Equations, Volume 42, Issue 4, July 2026.
ABSTRACT The main purpose of this paper is to design a fully discrete local discontinuous Galerkin (LDG) scheme for the generalized Benjamin–Ono equation. First, we prove the L2$$ {L}^2 $$‐stability for the proposed semi‐discrete LDG scheme and obtained a suboptimal order of convergence for power nonlinear flux.

On a Fourier problem for evolution differential-functional equations with nonlocal boundary conditions [PDF]

, 2003
The boundary value problems with nonlocal boundary conditions have been treated in many works. Individually, Day [1] while studying quasistatic thermoelasticity posed a model involving parabolic equation with nonlocal boundary condition.

A Convergent Fourier Spectral Galerkin Method for the Fractional Camassa–Holm Equation

Numerical Methods for Partial Differential Equations, Volume 42, Issue 4, July 2026.
ABSTRACT We analyze a Fourier spectral Galerkin method for the fractional Camassa–Holm (fCH) equation involving a fractional Laplacian of exponent α∈[1,2]$$ \alpha \in \left[1,2\right] $$ with periodic boundary conditions. The semi‐discrete scheme preserves both mass and energy invariants of the fCH equation.

Information Dynamics and Learning in Complex Adaptive Systems: Toward a Transdisciplinary Framework

Systems Research and Behavioral Science, Volume 43, Issue 4, Page 1344-1363, July/August 2026.
ABSTRACT This article develops a framework for understanding learning and adaptation in complex adaptive systems. Drawing from neuroscience, systems theory, information theory and quantum field theory, it examines how information processing, plasticity and systemic coherence emerge from distributed, nonlinear and feedback‐driven interactions. It argues

Thermal Buckling and Vibrational Characteristics of Curved Sandwich Nanoplates Featuring Anti‐Trichiral Auxetic Core and Graphene‐Reinforced Foam Surface Layers

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 7, July 2026.
ABSTRACT This study presents a rigorous investigation into the thermomechanical vibration characteristics of functionally graded (FG) curved sandwich nanoplates. The novelty of this research lies in the simultaneous evaluation of diverse porosity distributions, graphene reinforcement levels, and curvature configurations within a unified framework that ...

Morphological Dating of Fluvial Terrace Risers Across Spatial and Temporal Scales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fluvial terraces are valuable terrestrial records of past climatic and tectonic changes. Morphological dating, which quantifies the degradation of the riser between two terraces, offers a relatively simple and cost‐effective alternative to other dating methods.

K-dimensional nonlocal boundary-value problems at resonance

Electronic Journal of Differential Equations, 2015
Summary: We show the existence of at least one solution to the system of nonlocal resonant boundary-value problem \[ x''= f(t,x),\quad x'(0)= 0,\quad x'(1)= \int^1_0 x'(s)\,dg(s), \] where \(f: [0,1]\times\mathbb{R}^k\to \mathbb{R}^k\), \(g: [0,1]\to \mathbb{R}^k\).

Capturing Secondary Kinetic Instabilities in Three‐Dimensional Dayside Reconnection Using an Improved Gradient‐Based Closure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower‐hybrid drift and secondary drift‐kink instabilities in particular have been shown by kinetic simulations to modify the reconnection and introduce significant turbulence and ...
