Big data analytics on PMU measurements [PDF]

2014 11th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2014
Phasor Measurement Units (PMUs) are being rapidly deployed in power grids due to their high sampling rates. PMUs offer a more current and accurate visibility of the power grids than traditional SCADA systems. However, the high sampling rates of PMUs bring in two major challenges that need to be addressed to fully benefit from these PMU measurements. On

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Volatile ZrO2 Antiferroelectric Tunnel Junctions for Rapid, Energy‐Efficient Physical Reservoir Computing

Advanced Science, EarlyView.
An antiferroelectric tunnel junction serves as a reservoir computing node, where field‐induced phase transitions and spontaneous ZrO2 relaxation deliver nonlinear fading memory. An In‐Ga‐Zn oxide interlayer enlarges the memory margin and multibit state richness.

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

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).
