Not all money is created equal: The concept of a hierarchy of money

Review of Economic Perspectives
The concept of a hierarchy of money or the idea that a number of instruments constitute money and that they are hierarchically related to one another is relatively recent and yet quite widespread.

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

, 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

The Broad-lined Type Ic SN 2003jd [PDF]

, 2007
The results of a world-wide coordinated observational campaign on the broad-lined Type Ic SN 2003jd are presented. In total, 74 photometric data points and 26 spectra were collected using 11 different telescopes.

Clearing the Dust from Globular Clusters

, 2008
Recent Spitzer observations of the globular cluster M15 detected dust associated with its intracluster medium. Surprisingly, these observations imply that the dust must be very short-lived compared to the time since the last Galactic plane crossing of ...

Gamma-ray Emission from Crushed Clouds in Supernova Remnants

, 2010
It is shown that the radio and gamma-ray emission observed from newly-found "GeV-bright" supernova remnants (SNRs) can be explained by a model, in which a shocked cloud and shock-accelerated cosmic rays (CRs) frozen in it are simultaneously compressed by

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

, 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.

Hypernova Nucleosynthesis and Implications for Cosmic Chemical Evolution [PDF]

, 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 ...

Novel Porous Gold Microspheres Anisotropic Conductive Film (PGMS‐ACF) with High Compression Ratio for Flip Chip Packaging

Advanced Electronic Materials, Volume 11, Issue 12, August 6, 2025.
This research presents a novel method for preparing porous gold microspheres with controllable particle size. The method can overcome the long‐term challenge of manufacturing ultrafine (1–10 µm) porous gold conductive microspheres. Compared to commercial polymer composite conductive microspheres anisotropic conductive film （ACF), porous gold ...

On the endogeneity of the money stock. A rejoinder

PSL Quarterly Review, 2014
In this brief rejoinder the author responds David I. Fand’s clarification regarding the classification of the nominal money stock as exogenous or endogenous based on whether or not the variable is controlled by the monetary authorities.

The Progenitor of the New COMPTEL/ROSAT Supernova Remnant in Vela

, 1999
We show that (1) the newly discovered supernova remnant (SNR), GRO J0852--4642/RX J0852.0--4622, was created by a core-collapse supernova of a massive star, and (2) the same supernova event which produced the $^{44}$Ti detected by COMPTEL from this ...
