Water Resources Research, Volume 62, Issue 8, August 2026.Abstract Capillary pressure–saturation relationships are central to modeling multiphase flow in porous media, yet conventional formulations often neglect how pore‐scale flow organization and interfacial geometry evolve during displacement. Here, we investigate curvature‐derived capillary pressure during immiscible two‐phase displacement using ...

Synthesis of Cascadable DDCC-Based Universal Filter Using NAM
Applied Sciences, 2015 A novel systematic approach for synthesizing DDCC-based voltage-mode biquadratic universal filters is proposed. The DDCCs are described by infinity-variables’ models of nullor-mirror elements which can be used in the nodal admittance matrix expansion ...

Type II degenerations of K3 surfaces of degree 4
Proceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.Abstract We study Type II degenerations of K3 surfaces of degree 4 where the central fibre consists of two rational components glued along an elliptic curve. Such degenerations are called Tyurin degenerations. We construct explicit Tyurin degenerations corresponding to each of the 1‐dimensional boundary components of the Baily–Borel compactification of

On the Meaning of Localization in Non‐Local Quantum Field Theory
Annalen der Physik, Volume 538, Issue 6, June 2026.In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

DV-EXCCCII Based Resistor-Less Current-Mode Universal Biquadratic Filter
Advances in Technology Innovation, 2023 This study aims to present a new resistor-less current-mode multi-input single-output universal filter. The current-mode’s design approach is used to obtain the proposed circuit. This circuit employs a single differential voltage extra-X current controlled current conveyor (DV-EXCCCII) and two grounded capacitors.

The Role of Price‐Volatility Cojumps in Volatility Forecasting
Journal of Futures Markets, Volume 46, Issue 5, Page 931-951, May 2026.ABSTRACT This paper investigates whether simultaneous jumps in prices and volatility improve volatility forecasting. Using up‐to‐date high‐frequency S&P 500 and VIX data, we identify price‐volatility cojumps at the intraday granularity and construct upside, downside, and asymmetric measures.
