Peak-ratio analysis method for enhancement of LOM protection using M class PMUs [PDF]

open access: yes, 2016
A novel technique for loss of mains (LOM) detection, using Phasor Measurement Unit (PMU) data, is described in this paper. The technique, known as the Peak Ratio Analysis Method (PRAM), improves both sensitivity and stability of LOM protection when ...

Born to Fear the Machine? Genetic and Environmental Influences on Negative Attitudes toward AI Agents

open access: yesAdvanced Science, Volume 12, Issue 35, September 18, 2025.
Why do some people fear or distrust AI agents more than others? This twin study shows that negative attitudes toward AI may partly stem from genetic factors, linking them to traits like victim sensitivity and moral beliefs. These findings show that it is not only nurture but also nature that shapes our views of AI, with implications for future human–AI

Impact of distributed generation mix on the effectiveness of islanded operation detection [PDF]

open access: yes, 2015
Distributed generation can be understood as a process where large scale power generation is gradually replaced by smaller power generation facilities with reduced power yield, and mostly connected at the system distribution level.

The reduction in maize leaf growth under mild drought affects the transition between cell division and cell expansion and cannot be restored by elevated gibberellic acid levels [PDF]

open access: yes, 2018
Growth is characterized by the interplay between cell division and cell expansion, two processes that occur separated along the growth zone at the maize leaf.

Genetic and Environmental Contributions to Child Height in Low‐ and Middle‐Income Countries

open access: yesAmerican Journal of Human Biology, Volume 37, Issue 9, September 2025.
ABSTRACT Background Child height is influenced by genetic and environmental factors. However, it is unclear how these factors vary by geographical region and by study design, particularly in low‐ and middle‐income countries (LMIC), where data is scarce.

Modified Q–f Droop Curve Method for Islanding Detection With Zero Non-Detection Zone

open access: yesIEEE Access, 2021
In this paper, a modified Q-f droop curve method for the inverter-based distributed generator is proposed. The proposed method has merits such as detecting islanding with zero non-detection zone, negligible effects on power quality, and simple ...

Improved Theoretical Estimates of the Zonal Propagation of Global Nonlinear Mesoscale Eddies

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract Mesoscale eddies are essential for transport and mixing processes in the global ocean, with their characteristic westward propagation being a significant finding from the satellite altimetry era. Traditional predictions of their zonal propagation rely on the theoretical phase speed of long baroclinic Rossby waves; however, this approach is ...

Automated and Fully Validated High‐Throughput LC‐MS/MS Assay for Analyzing Multiple Drugs of Abuse in Oral Fluids Using Novel Features in Sample Preparation and Chromatographic Conditions

open access: yesJournal of Mass Spectrometry, Volume 60, Issue 5, May 2025.
ABSTRACT Oral fluid sampling offers advantages over other biological matrices, mainly due to its noninvasive procedure avoiding privacy intrusion. The fully automated sample preparation procedure is based on salting‐out assisted liquid–liquid extraction (SALLE) combined with high‐efficiency LC‐MS/MS methods for both screening and confirmation of 37 ...
