Onset of Electron Acceleration in a Flare Loop [PDF]

open access: yes, 2014
We carried out detailed analysis of X-ray and radio observations of a simple flare loop that occurred on 12th August 2002, with the impulsive hard X-ray (HXR) light curves dominated by a single pulse. The emission spectra of the early impulsive phase are

Spectral Denoising for Accelerated Analysis of Correlated Ionic Transport [PDF]

open access: yesPhysical Review Letters, 2021
Computation of correlated ionic transport properties from molecular dynamics in the Green-Kubo formalism is expensive, as one cannot rely on the affordable mean square displacement approach. We use spectral decomposition of the short-time ionic displacement covariance to learn a set of diffusion eigenmodes that encode the correlation structure and form

Escape-limited Model of Cosmic-ray Acceleration Revisited [PDF]

open access: yes, 2009
The spectrum of cosmic rays (CRs) is affected by their escape from an acceleration site. This may have been observed not only in the gamma-ray spectrum of young supernova remnants (SNRs) such as RX J1713.7-3946, but also in the spectrum of CRs showering ...

Spectral Variability Signatures of Relativistic Shocks in Blazars [PDF]

open access: yes, 2018
Mildly relativistic, oblique shocks are frequently invoked as possible sites of relativistic particle acceleration and production of strongly variable, polarized multi-wavelength emission from relativistic jet sources such as blazars, via diffusive shock

SPEC2: SPECtral SParsE CNN Accelerator on FPGAs [PDF]

open access: yes2019 IEEE 26th International Conference on High Performance Computing, Data, and Analytics (HiPC), 2019
To accelerate inference of Convolutional Neural Networks (CNNs), various techniques have been proposed to reduce computation redundancy. Converting convolutional layers into frequency domain significantly reduces the computation complexity of the sliding window operations in space domain.

Scaling ratios for spectral accelerations caused by seismic site effect under site condition classifications in China

open access: yesFrontiers in Earth Science, 2023
The spectral accelerations (Sa), which are widely used as ground motion inputs in structural seismic designing, are significantly affected by local site conditions classified by near-surface geology. A novel approach of quantifying the scaling ratios for
