Anaphylaxis after stings by Vespula spp. – preventions, safety profile of venom immunotherapy, data from the Anaphylaxis Registry for West Pomerania Voivodeship, Poland [PDF]

Human Vaccines & Immunotherapeutics
Stings by Hymenoptera, especially by Vespula spp. are one of the most common causes of anaphylaxis among adults. The only method of preventing further episodes of anaphylaxis, in people with IgE allergy to Hymenoptera venom, is venom immunotherapy (VIT).

PMU-Based ROCOF Measurements: Uncertainty Limits and Metrological Significance in Power System Applications [PDF]

, 2019
In modern power systems, the Rate-of-Change-of-Frequency (ROCOF) may be largely employed in Wide Area Monitoring, Protection and Control (WAMPAC) applications. However, a standard approach towards ROCOF measurements is still missing.

Generative Adversarial Networks-Based Synthetic PMU Data Creation for Improved Event Classification

IEEE Open Access Journal of Power and Energy, 2021
A two-stage machine learning-based approach for creating synthetic phasor measurement unit (PMU) data is proposed in this article. This approach leverages generative adversarial networks (GAN) in data generation and incorporates neural ordinary ...

Placing problematic media use in context: a research synthesis, person-centric framework, and chart review among a clinical sample of US youth [PDF]

Frontiers in Psychiatry
Understanding the dynamics underlying problematic media use (PMU) is crucial in today’s digital society. The maintaining factors driving problematic use span both bio-psychological and social factors, necessitating the development of an integrative, meta-

Robust Event Classification Using Imperfect Real-World PMU Data [PDF]

IEEE Internet of Things Journal, 2021
This article studies robust event classification using imperfect real-world phasor measurement unit (PMU) data. By analyzing the real-world PMU data, we find that it is challenging to directly use this data set for event classifiers due to the low data ...
