A model for the Z-track phenomenon in GX 5-1 and observational evidence for the physical origins of the kHz QPO [PDF]

open access: yes, 2008
We present results of a combined investigation of the spectral and kHz QPO evolution around the Z-track in GX 5-1 based on high-quality RXTE data. The Extended ADC emission model provides very good fits to the spectra, the results pointing clearly to a ...

EVSS‐Based Simulation Techniques for the Viscoelastic Fluids With Pure Polymer Melts Using Three‐Field Approach

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 492-509, April 2026.
This paper presents a finite element method for simulating highly viscoelastic flows of pure polymer melts using the Elastic Viscous Stress Splitting formulation. The method avoids higher‐order derivatives in the weak formulation by reformulating the convective term in the constitutive equation.

Pinus nigra and Pinus brutia Extracts Inhibit Quorum Sensing in Pseudomonas aeruginosa PAO1 with Minimal Impact on Fibroblast Cell Viability and Calcium Deposition

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Extracts of Pinus nigra and Pinus brutia inhibit quorum sensing in Pseudomonas aeruginosa PAO1 by reducing pyocyanin and elastase production. This effect is associated with the downregulation of QS‐related genes, including lasR, lasI, rhlI, and rhlR. Additionally, the extracts exhibit minimal, dose‐ and time‐dependent effects on the metabolic activity ...

Review of Memristors for In‐Memory Computing and Spiking Neural Networks

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...
