Optimization of Ultrasound‐Assisted Extraction of Seabuckthorn (Hippophae salicifolia) Seed Oil With the Use of Response Surface Methodology

Future Postharvest and Food, Volume 3, Issue 3, Page 334-349, September 2026.
Ultrasound‐assisted extraction (UAE) of seabuckthorn seed oil enhanced yield (17.95%), antioxidant activity (IC50: 5.25 μg/mL), and carotenoid content (266.63 mg/100 g). The oil, rich in unsaturated fatty acids (83.15%), exhibited superior quality, thermal stability, and potential applications in food, cosmetics, and pharmaceuticals, making UAE a ...

Computing the Solutions of the Combined Korteweg-de Vries Equation by Turing Machines [PDF]

Electronic Proceedings in Theoretical Computer Science, 2010
In this paper, we study the computability of the initial value problem of the Combined KdV equation. It is shown that, for any integer s>2, the nonlinear solution operator which maps an initial condition data to the solution of the Combined KdV ...

A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Lax Pairs for BKM Hierarchy

Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.
ABSTRACT We construct Lax pairs for the recently (2023) introduced integrable PDE systems known as the BKM equations. As many known and previously studied integrable systems are special cases of the BKM systems, our construction provides Lax pairs for many integrable hierarchies, including previously studied ones such as Camassa–Holm, Dullin–Gottwald ...

A new approach for the analysis of evolution partial differential equations on a finite interval

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract We show that, for certain evolution partial differential equations, the solution on a finite interval (0,ℓ)$(0,\ell)$ can be reconstructed as a superposition of restrictions to (0,ℓ)$(0,\ell)$ of solutions to two associated partial differential equations posed on the half‐lines (0,∞)$(0,\infty)$ and (−∞,ℓ)$(-\infty,\ell)$.

Fluorinated and B‐Vinylated Tris(pyridyl)borate in Copper(I) Coordination Chemistry

European Journal of Inorganic Chemistry, Volume 29, Issue 24, 21 August 2026.
Coordinatively flexible tris(pyridyl)borate stabilizes copper coordination complexes, including those with ethylene and carbon monoxide. Fluorinated tris(pyridyl)borate with a vinyl substituent on boron was synthesized and comprehensively characterized, expanding the diversity and functional versatility of the poly(pyridyl)borate ligand family.

Exploring Current Perspectives on a Doctor of Philosophy Degree in Genetic Counseling

Journal of Genetic Counseling, Volume 35, Issue 4, August 2026.
ABSTRACT Since the profession's inception, the entry‐level and terminal degree for genetic counselors (GCs) has remained a master's degree. Interest in a PhD in Genetic Counseling has been explored previously; however, no studies on this topic have been published since 2015.

Painlevé integrability and multiple soliton solutions for the extensions of the (modified) Korteweg-de Vries-type equations with second-order time-derivative

Alexandria Engineering Journal
This work introduces two (3+1)-dimensional expansions of the Korteweg–de Vries (KdV) and modified KdV (mKdV) equations. These extensions incorporate a second-order time-derivative term, similar to the Boussinesq equation. The Painlevé test is utilized to

Observations of High‐Frequency Internal Waves Near Submesoscale Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Nonlinear high‐frequency internal waves (HIWs) can occur at oceanic frontal interfaces but are rarely observed directly. This study presents field observations of HIWs near submesoscale fronts (SFs) in the northern Gulf of Mexico. A marine X‐band radar detected a series of organized bands, with a spacing of 50 ∼ 300 m, near SFs.

The Interactions of N-Soliton Solutions for the Generalized (2+1)-Dimensional Variable-Coefficient Fifth-Order KdV Equation

Advances in Mathematical Physics, 2015
A generalized (2+1)-dimensional variable-coefficient KdV equation is introduced, which can describe the interaction between a water wave and gravity-capillary waves better than the (1+1)-dimensional KdV equation.
