abstract on 6 december 2006, australia and korea announced a joint study on a possible australia-korea free trade agreement (akfta) to promote trade and economic relations between the two countries. the paper provides empirical evidence on the possible gains and their transmission mechanism from this agreement. significantly, it uses a new economic policy modelling approach, the endogenous grav...

In order to elucidate the mechanisms by which a strong shock terminates reentrant wavefronts, we employed phase analysis techniques to study phase singularity dynamics in a finite element model of cardiac tissue. We located postshock phase singularities and traced their movement and survival for sixteen monophasic shocks applied at different times during the rotation of a spiral wave. Our analy...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

This paper studies conditions under which demand-side shocks can generate realistic business cycles in RBC models. Although highly persistent demand shocks are necessary for generating procyclical investment, variable capacity utilization and habit formation can reduce the required degree of persistence. Keywords: Demand Shocks; Hall’s Residual; Real Business Cycles; Crowding Out; Investment Dy...

FrCas(E) is a mouse retrovirus that causes a fatal noninflammatory spongiform neurodegenerative disease with pathological features strikingly similar to those induced by transmissible spongiform encephalopathy (TSE) agents. Neurovirulence is determined by the sequence of the viral envelope protein, though the specific role of this protein in disease pathogenesis is not known. In the present stu...

This paper generalizes Yeh Lam’s shock model for renewal shock arrivals and random threshold. Several interesting statistical measures are explicitly obtained. A few special cases and an optimal replacement problem are also discussed. Keywords— shock model, optimal replacement, random threshold, shocks.
