Analysis of cation‐π interactions using quantum chemistry and statistical analysis of high‐resolution protein structures

The FEBS Journal, EarlyView.
Shown is a typical detail of a high‐resolution crystal structure (PDB ID 1B5E, chain A) showing the nearness of a phenylalanine residue, Phe24, and a lysine residue, Lys32, that are not engaged in the proposed cation–π interaction. The study statistically examines charged residues near phenylalanine's aromatic ring, supported by quantum chemical ...

Is HPC for you? A collective perspective on adopting high‐performance computing for bioimage analysis in imaging facilities

Journal of Microscopy, EarlyView.
Abstract Biomedical sciences use various imaging technologies and bioimage analysis has become data‐intensive, often requiring resources that exceed those available on personal laptop computers or workstations. High‐performance computing (HPC) can solve most of the problems connected to the data burden of modern bioimaging, offering scalable and ...

Fault Diagnosis Method for DC Current Transformers Based on Deep Learning Hybrid Model

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
Aiming at the problems of scarce fault samples, strong noise interference and complex feature coupling in the current DCCT fault diagnosis process, a DCCT fault diagnosis method based on a hybrid deep learning model is proposed. The performance of the proposed method is verified through experiments.

Dynamic Modeling of Supercapacitor Self‐Discharge Through a Solar Cell in Photosupercapacitor Systems

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 11, November 2026.
In photosupercapacitor configurations, the supercapacitor discharges through the solar cell under dark conditions without load. If the supercapacitor voltage overcomes the threshold voltage of the cell (VSC > VON), the cell becomes forward‐biased and its impedance |Z| drops, allowing the flow of a reverse current.

Dynamic Resonance Analysis and Oscillation Damping of Multiterminal DC Grids

IEEE Access, 2017
Voltage-source converter-based multiterminal high-voltage direct current (VSC-MTDC) systems/grids are prone to system instability. This critical issue is overlooked in the literature. In order to improve system stability, this paper proposes an effective

In Silico Study of Degradation in Host Molecular Materials for OLEDs

Advanced Theory and Simulations, Volume 9, Issue 10, October 2026.
Static and dynamic simulations provide complementary views of degradation in OLED host materials. Thermodynamic descriptors identify likely bond‐dissociation pathways, while non‐adiabatic molecular dynamics reveals the pathways realized during excited‐state evolution.

Electrical resonance mitigation scheme based on damping controller for wind farm integration through VSC-HVDC system

The Journal of Engineering, 2019
Voltage Source Converter based High Voltage Direct Current Transmission (VSC-HVDC) technology promotes the development and utilisation of large-scale wind power, but the power oscillation might occur due to the interaction between two control systems. In

Integrated Experimental, Chemometric, and In Silico Analyses of Larvicidal Supercritical Extracts From Myrtaceae Species Against Aedes aegypti

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The cross‐validated regression tree showed modest predictive performance. Mortality was not significantly associated with the first two PCA axes. Molecular modeling generated testable ligand–target hypotheses. Psidium cattleianum had lower LD50. The larvicidal activity of the crude extracts could not be attributed to individual constituents.
