Multi-orbital simplified parquet equations for strongly correlated electrons

open access: yes, 2010
We extend an approximation earlier developed by us for the single-impurity Anderson model to a full-size impurity solver for models of interacting electrons with multiple orbitals.

A Transcriptional Map of Human Tonsil Architecture: Beyond the Sum of (Single Cell) Parts

open access: yesEuropean Journal of Immunology, Volume 56, Issue 1, January 2026.
Picture‐book compartmentalization makes tonsillar tissue an ideal model to study spatial immunology. Using single‐molecule imaging (SMI) of whole‐tissue sections, we showcase many an alternative view on tissue composition and architecture that these data and concomitant analyses provide—at the level of single cells, cellular neighborhoods, and ...

Stability of self-consistent solutions for the Hubbard model at intermediate and strong coupling

open access: yes, 1999
We present a general framework how to investigate stability of solutions within a single self-consistent renormalization scheme being a parquet-type extension of the Baym-Kadanoff construction of conserving approximations.

An Efficient Intrusion Detection System Using Domain‐Aware Meta‐Learning with Adapter‐Based Few‐Shot Adaptation in Vehicular Ad‐Hoc Networks (VANETs)

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
Integrated IDS pipeline for anomaly detection in vehicular ad hoc networks (VANETs), from domain construction to adapter tuning, with decision nodes and diagnostic feedback. ABSTRACT Vehicular ad hoc networks (VANETs) face critical security threats, including false position reports, replayed messages and denial of service (DoS) attacks, which can ...

A Transmittance-optimized, Point-focus Fresnel Lens Solar Concentrator [PDF]

open access: yes, 1984
The development of a point-focus Fresnel lens solar concentrator for high-temperature solar thermal energy system applications is discussed. The concentrator utilizes a transmittance-optimized, short-focal-length, dome-shaped refractive Fresnel lens as ...

A mean-field theory of Anderson localization

open access: yes, 2004
Anderson model of noninteracting disordered electrons is studied in high spatial dimensions. We find that off-diagonal one- and two-particle propagators behave as gaussian random variables w.r.t. momentum summations. With this simplification and with the

AI‐Based Approaches for Analyzing EEG Signals to Identify Epileptic Seizures: A Survey

open access: yesApplied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Electroencephalography (EEG) is a fundamental tool for monitoring brain activity and is widely used in the diagnosis and management of epilepsy. With the growing prevalence of epilepsy and the limitations of manual EEG interpretation, artificial intelligence (AI) techniques, particularly machine learning (ML) and deep learning (DL), have gained ...

Fermi-edge singularity and the functional renormalization group

open access: yes, 2018
We study the Fermi-edge singularity, describing the response of a degenerate electron system to optical excitation, in the framework of the functional renormalization group (fRG).

Enhancing Wind Turbine Diagnostics With SCADA‐Vibration Fusion, Contrastive Learning, and Linear Predictive Coefficients

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Wind energy plays a pivotal role in the transition to sustainable power generation. However, maintaining the reliability and efficiency of wind turbine (WT) remains a significant challenge due to complex operational conditions and the high cost associated with unexpected failures.
