Hypernova Nucleosynthesis and Galactic Chemical Evolution [PDF]

open access: yes, 2001
We study nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs) for both spherical and aspherical explosions.

Optical Emission from Aspherical Supernovae and the Hypernova SN 1998bw

open access: yes, 2005
A fully 3D Monte Carlo scheme is applied to compute optical bolometric light curves for aspherical (jet-like) supernova explosion models. Density and abundance distributions are taken from hydrodynamic explosion models, with the energy varied as a ...

CO J = 2 - 1 Emission from Evolved Stars in the Galactic Bulge

open access: yes, 2013
We observe a sample of 8 evolved stars in the Galactic Bulge in the CO J = 2 - 1 line using the Submillimeter Array (SMA) with angular resolution of 1 - 4 arcseconds.

The quest for global monetary policy coordination

open access: yesEconomics: Journal Articles, 2019
This paper puts forward a proposal to help monetary policies confront the challenge of the “normalisation” of money creation and interest rates. The difficult unwinding of years of unorthodox policies put financial stability at risk in major monetary ...

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

Financial technology, macroeconomic uncertainty, and commercial banks’ proactive risk-taking in China

open access: yesChina Economic Quarterly International, 2023
In this paper, we collect the annual data of 145 commercial banks in China from 2010 to 2019 and use a panel data fixed-effect model to study how fintech (financial technology) affects the influence of macroeconomic uncertainty on commercial banks ...

Thermal Conductive Network Construction and Enhanced Thermal Conductivity in Mica Tape Composites for Large Generators by Pre‐Placed h‐BN@PDA‐Modified Mica Paper

open access: yesHigh Voltage, EarlyView.
ABSTRACT The lower thermal conductivity (TC) of mica tape hinders the evolution of large generators towards higher voltage and capacity. To enhance the TC of the mica tape, with the help of the three‐dimensional (3D) multi‐layer framework of the mica paper, a 3D polydopamine‐coated boron nitride (h‐BN@PDA) TC network was constructed by pre‐placing h‐BN@
