Testing Alternative Theories of the Property Price-Trading Volume Correlation
This article examines the correlation between the real housing price and trading volume. Contrary to the predictions of standard rational expectation models, a robust positive correlation between the two variables is identified. While no clear lead-lag relationship is found in the raw data, which is more consistent with the downpayment effect model, the medium-run component of the trading volume tends to lead (and Granger cause) the corresponding component of the property price, which is more consistent with the search theoretic model. An explanation for this difference in behavior is suggested and several future research directions are provided.
TOM: Why Isnât Price Enough?
In an efficient market, differences in quality should be fully reflected in differences in price. This paper examines a highly active residential property market and verifies whether housing attributes can explain time on the market (TOM) in addition to prices. In contrast to the previous literature, only the price ratio and inflation factor are found to be critical in affecting TOM. An interpretation of the results is suggested, along with some directions for future research.TOM, price ratio, inflation factor, physical attribute, time aggregation
Glass Transition and Relaxation in Pressure-Quenched Borate and Borosilicate Glasses:An invited talk
A Structural Connection to the Configurational Heat Capacity of Borate-Silicate Glass Forming Liquids
Failure to Reproduce the Results of "A new transferable interatomic potential for molecular dynamics simulations of borosilicate glasses''
We reproduced the simulations described in Wang et al [J. Non-Cryst. Sol.,
498 (2018) 294-304] and found we could not obtain the results reported. The
root cause was identified to be incorrect atom masses in the original
simulation files. As a consequence, the potential does not reproduce the
experimental glass density -- and presumably, other structural properties --
and should be considered with great caution

Megahertz-rate ultrafast X-ray scattering and holographic imaging at the European XFEL
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers access to X-rays with unprecedented brightness, coherence and pulse duration. All XFEL facilities built until recently provided X-ray pulses at a relatively low repetition rate, with limited data statistics. Here, results from the first megahertz-repetition-rate X-ray scattering experiments at the Spectroscopy and Coherent Scattering (SCS) instrument of the European XFEL are presented. The experimental capabilities that the SCS instrument offers, resulting from the operation at megahertz repetition rates and the availability of the novel DSSC 2D imaging detector, are illustrated. Time-resolved magnetic X-ray scattering and holographic imaging experiments in solid state samples were chosen as representative, providing an ideal test-bed for operation at megahertz rates. Our results are relevant and applicable to any other non-destructive XFEL experiments in the soft X-ray range
Quick Sex-Determination of the Asiatic Garden Beetle, Maladera castanea (Coleoptera: Scarabaeidae)
The orientation of the posterior abdominal sternite and pygidium allows for quick sex-determination of Maladera castanea (Arrow) (Coleoptera: Scarabaeidae: Melolonthinae) adults with a dissecting microscope or hand lens. Maladera castanea (the Asiatic garden beetle) is an emerging pest of field crops and this information will help researchers to conduct studies more easily on its biology and ecology
