The continuous Newton-Raphson method can look ahead [PDF]

open access: yes, 2003
This paper is about an intriguing property of the continuous Newton-Raphson method for the minimization of a continuous objective function f: if x is a point in the domain of attraction of a strict local minimizer x* then the flux line of the Newton ...

A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT A stable sequential quadratic numerical optimization technique is proposed to compute critical flutter speeds without resorting to complex algebra. The solution of the traditional eigenproblem stated in the frequency domain, and whose complex conjugate eigenvalues provide insights on the stability of the dynamic aeroelastic response, is ...

Computational Design and Theoretical Evaluation of Novel Heterocyclic Energetic Materials Based on 5‐H‐Imidazo‐[4,5‐c]‐Pyridazine and 1,2,4‐Triazolo‐[4,3‐a]‐Pyrazine Scaffolds

open access: yesJournal of Computational Chemistry, Volume 47, Issue 23, September 5, 2026.
Eighty‐eight novel energetic compounds based on 5‐H‐imidazo‐[4,5‐c]pyridazine and 1,2,4‐triazolo‐[4,3‐a]pyrazine scaffolds, functionalized with nitro, nitramino, azido, and nitrate ester groups, were theoretically evaluated by DFT. Nine candidates surpassed RDX in density and detonation performance while maintaining acceptable impact sensitivity.

A Real‐Time Digital Twin for Human Cardiovascular Applications

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 9, September 2026.
A real‐time digital twin was developed using the reduced‐order unscented Kalman filter (ROUKF) to estimate left ventricular contractility from synthetic and in vivo left ventricular pressure measurement data. The results were promising, with identifiable parameter estimates and a stable mathematical model, highlighting the potential for real‐time ...

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, Volume 255, Issue 9, Page 867-880, September 2026.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

A Hybrid FEM–ML Framework for Magnetohydrodynamic Combined Convective Heat Transfer Performance of Hybrid Nanofluid Flow in a Horizontal Wavy Channel

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework

A Newton–Raphson-Based Optimizer for the Optimal Generation Allocation Problem Considering Operation and Maintenance Costs of Renewable Energy Sources

open access: yesInternational Transactions on Electrical Energy Systems
A large share of the world’s electricity is produced from coal and similar energy sources. Although these sources are commonly used, they carry significant costs and environmental issues, including the emission of harmful gases that contribute to global ...
