An Effective Index for Islanding Detection Based on Fast Discrete S-Transform
Advances in Electrical and Electronic Engineering, 2019 Passive methods of islanding detection have the advantage of not perturbing the system, but they suffer from large Non-Detection Zone (NDZ) and unpredictable detection time. In this paper, a new passive scheme for islanding detection, based on estimating

Morphological instabilities of a thin film on a Penrose lattice: a Monte Carlo study
, 2005 We computed by a Monte Carlo method the thermal relaxation of a polycrystalline thin film deposited on a Penrose lattice. The thin film was modelled by a 2 dimensional array of elementary domains, which have each a given height.

Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Microgrid Islanding Detection Using D-PMU and Phase Angle Analysis of Negative Sequence Impedance
IEEE AccessUnintentional islanding detection is a major challenge during the operation of a microgrid. When islanding occurs, distributed energy resources (DERs) need to be disconnected quickly, under 2 seconds, which makes fast islanding detection crucial.

Annals of the American Association of Geographers, 2023 Islandness is a contested concept, not just between disciplines but also cultures, entangled with what islands, island studies, and island identity are understood to be. The purpose of this article is to explore some of these different meanings, without necessarily unifying or reconciling them, with the aim of keeping multiple understandings of ...

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
