The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube
ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

This research investigates the propagation of elastic waves in uniform thin plates using the framework of nonlocal elasticity theory. Focusing on plates with stress-free boundary surfaces, the study derives and analyses two distinct dispersion relations corresponding to symmetrical and antisymmetrical wave modes with respect to the plate’s mid-plane ...

Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Analysis of a model for banded vegetation patterns in semi-arid environments with nonlocal dispersal
Vegetation patterns are a characteristic feature of semi-arid regions. On hillsides these patterns occur as stripes running parallel to the contours.

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

Electrochemical experiments reveal what happens, whereas first principles calculations explain why. Emerging computational electrochemistry is bridging these perspectives, enabling quantitative understanding of electrode/electrolyte interfaces and enabling the rational design of next‐generation energy storage materials.

Arbitrary Wavefront Manipulation in Real Space and Momentum Space Based on Elliptical Structures
Leveraging elliptical structures—while preserving real space arbitrary wavefront manipulation—we generalize the manipulation to momentum space rather than only sustaining topological singularities. Multifunctional integrated outputs, such as beam deflection and focusing, can be flexibly achieved in the near–infrared communication band, and the ...

ON A PREDATOR-PREY SYSTEM WITH NONLOCAL DISPERSAL (Qualitative Theory on ODEs and their applications to Mathematical Modeling) [PDF]
We are concerned with the propagation dynamics of a predator-prey system with nonlocal dispersal. We obtain a threshold phenomenon for the invasion of the predator into the habitat of the aborigine prey.

The transition from cryogenic distillation to polymeric sorbents for light hydrocarbon purification is crucial for energy and environmental sustainability. The polymeric sorbents are engineered to separate gas mixtures based on their specific properties.
