A New Diagnostic Algorithm for Multiple IGBTs Open Circuit Faults by the Phase Currents for Power Inverter in Electric Vehicles

open access: yesEnergies, 2018
In order to simplify the application and improve diagnostic speed of the diagnostics, a novel method to diagnose multiple open circuit faults in insulated gate bipolar transistors (IGBTs) by three-phase currents for power inverter in electric vehicles is

Erdheim-Chester Disease: Utility of 18F-FDG Positron Emission Tomography [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Erdheim-Chester Disease (ECD) is a rare non Langerhans cell histiocytosis of unknown origin with multiorgan involvement. We report a case of a man who presented to us with haematuria, asthenia, fever, nausea and malleolar oedema.

ARCADE 2 Observations of Galactic Radio Emission [PDF]

open access: yes, 2009
We use absolutely calibrated data from the ARCADE 2 flight in July 2006 to model Galactic emission at frequencies 3, 8, and 10 GHz. The spatial structure in the data is consistent with a superposition of free-free and synchrotron emission.

Attosecond field emission

open access: yesNature, 2023
AbstractField emission of electrons underlies great advances in science and technology, ranging from signal processing at ever higher frequencies1 to imaging of the atomic-scale structure of matter2 with picometre resolution. The advancing of electron microscopy techniques to enable the complete visualization of matter on the native spatial (picometre)

Brake wear-derived particles: Single-particle mass spectral signatures and real-world emissions

open access: yesEnvironmental Science and Ecotechnology, 2023
Brake wear is an important but unregulated vehicle-related source of atmospheric particulate matter (PM). The single-particle spectral fingerprints of brake wear particles (BWPs) provide essential information for understanding their formation mechanism ...

Discovery of an Apparent High Latitude Galactic Supernova Remnant [PDF]

open access: yes, 2015
Deep H$\alpha$ images of a faint emission complex 4.0 x 5.5 degrees in angular extent and located far off the Galactic plane at l = 70.0 degrees, b=-21.5 degrees reveal numerous thin filaments suggestive of a supernova remnant's shock emission.
