Radon volatilization mechanism into the gas phase was hypothesized to explain the anomalous decline in groundwater radon precursory to the 2003 M <Subscript>W</Subscript> = 6.8 Chengkung earthquake in Taiwan. We initiated the monitoring of both radon and methane in the groundwater since November 2007 at well D1 in...</subscript>

The active Chihshang fault in the southern segment of longitudinal valley of eastern Taiwan is part of the suture boundary between the Eurasia plate and the Philippine Sea plate. Radon anomalies in groundwater were recorded prior to three major earthquakes—(1) 2003 M <Subscript>w</Subscript> = 6.8 Chengkung, (2)...</subscript>

We present an equilibrium framework in which asset prices, default-free term structure and default premia are determined simultaneously.

Knowledge of soil hydraulic properties is important for modeling hydrological processes and related contaminant transport. This study compared four methods in analyzing single-ring infiltrometer data to estimate the saturated hydraulic conductivity (Ks) and the water retention parameter (α)....

Informality is a wide-spread phenomenon across the globe. We show that firms in countries with better information sharing systems and greater financial sector outreach evade taxes to a lesser degree, an effect that is stronger for smaller firms, firms in smaller cities and towns, and firms in...

Periods of 6, 12, and 24 hr with equal amounts of flow and resting are simulated via finite difference approximations and compared with a continuously flowing system for both clogged and unclogged loamy sand.
