Detection of X-Ray Bursts in Astronomical Time Series: The Burst of GRO J1744-28 as an Example
The Astrophysical Journal, 2023 To automatically, accurately, and quickly detect local changes in time-series data continuously emitted by X-ray sources, an autoencoder-based unsupervised learning anomaly detection method is proposed.

Simultaneous Precipitation of Sub‐Relativistic Electron Microburst and Pulsating Aurora Electrons
Geophysical Research Letters, 2023 We have identified for the first time an energy‐time dispersion of precipitating electron flux in a pulsating aurora patch, ranging from 6.7 to 580 keV, through simultaneous in‐situ observations of sub‐relativistic electrons of microburst precipitations ...

Analysis of the Causes and Wind Field Structure of a Dry Microburst in a Weak Weather Background
Atmosphere, 2023 Dry microbursts in weak weather backgrounds, due to their small scale and general lack of precipitation, are often difficult to observe using weather radar. On the night of 26 April 2023, a dry microburst occurred at the Yinchuan Airport.

Duration of Individual Relativistic Electron Microbursts: A Probe Into Their Scattering Mechanism
, 2021 We used the Solar Anomalous and Magnetospheric Particle Explorer to identify and quantify the duration of relativistic, >1 MeV, electron microbursts. A typical relativistic microburst has a ≈100 millisecond (ms) duration, and the interquartile range of ...

Physical simulation of atmospheric microbursts [PDF]
Journal of Geophysical Research: Atmospheres, 2014 AbstractA laboratory simulation of atmospheric microbursts is presented. The physical model of the atmospheric phenomenon is reproduced at a reduced scale in a rotating tank (TURLab, Italy), the similitude is based on the Froude number. Different experiments were carried out varying the Rossby number, and the analysis of four significant cases is ...

Giant Pulses with Nanosecond Time Resolution detected from the Crab Pulsar at 8.5 and 15.1 GHz [PDF]
, 2010 We present a study of shape, spectra and polarization properties of giant pulses (GPs) from the Crab pulsar at the very high frequencies of 8.5 and 15.1 GHz. Studies at 15.1 GHz were performed for the first time.

Enabling low‐latency service function chains by merging duplicate match operations
IET Networks, 2022 Service function chains (SFCs) built by network functions (NFs) are usually required to be low‐latency, especially in some tight latency scenarios such as Distributed Denial of Service (DDoS) defense.
