Coupling Modelling and Fault Propagation Simulation Method for Power Grid‐Centric Urban Lifeline Systems Under Extreme Disasters

open access: yesEnergy Internet, Volume 2, Issue 3, Page 255-273, October 2025.
ABSTRACT The interconnection of urban critical infrastructure poses new challenges to the secure operation of power grid‐centric urban lifeline systems. The interdependencies among infrastructure systems increase the risk of cascading fault propagation, thereby threatening urban public safety.

Remnants from Gamma-Ray Bursts

open access: yes, 2000
We model the intermediate time evolution of a "jetted" gamma-ray burst by two blobs of matter colliding with the interstellar medium. We follow the hydrodynamical evolution of this system numerically and calculate the bremsstrahlung and synchrotron ...

Preparation Method and Performance Study of Nanocellulose/Epoxy Resin Composite Materials Modified by Multiple Approaches

open access: yesHigh Voltage, Volume 10, Issue 5, Page 1083-1098, October 2025.
ABSTRACT Nanocomposites are pivotal for enhancing epoxy resin performance, but traditional inorganic nanofillers' poor compatibility and nonrecyclability pose environmental concerns. This study utilises recyclable organic cellulose nanocrystals (CNC) to explore their modification impact on epoxy composite properties. Through infrared spectroscopy and X‐

Quantum affine algebras and universal R-matrix with spectral parameter, II

open access: yes, 1993
This paper is an extended version of our previous short letter \cite{ZG2} and is attempted to give a detailed account for the results presented in that paper. Let $U_q({\cal G}^{(1)})$ be the quantized nontwisted affine Lie algebra and $U_q({\cal G})$ be

CBDC and Trust in A Central Bank: Transitivity Of Preferences Vs. The Privacy Paradox

open access: yesFinancial Internet Quarterly
The privacy and anonymity of transactions are considered some of the biggest challenges when designing Central Bank Digital Currencies (CBDC). While many surveys show that people strongly prefer privacy in their transactions, behavioral theories suggest ...

Hypernova Nucleosynthesis and Implications for Cosmic Chemical Evolution [PDF]

open access: yes, 2001
We examine the characteristics of nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($\gsim 10^{52}$ ergs). Implications for the cosmic chemical evolution and the abundances in M82 are discussed.Comment: To appear in ...

A Luminous and Fast-Expanding Type Ib Supernova SN 2012au

open access: yes, 2013
We present a set of photometric and spectroscopic observations of a bright Type Ib supernova SN 2012au from -6d until ~+150d after maximum. The shape of its early R-band light curve is similar to that of an average Type Ib/c supernova.
