Fluid mechanic forces play a key role in the early development and progression of cardiovascular diseases, which predominantly occurs in areas of disturbed flow and low wall shear stress (WSS). In the present study, we perform particle image velocimetry (PIV) measurements in an anatomically realistic transparent flow phantom of a human carotid artery. Steady blood flow conditions are simulated ...

What happens if HIPC debt relief resources are not additional? We seek to answer this question by quantifying the impact of debt service payments and aid flows in crosscountry growth and investment regressions. Based on the regressions we assess the likely impact of debt relief with and without changes in the aid flows. The result is that one-for-one changes in debt service payments and officia...

I study a small open economy in which electoral uncertainty affects and is affected by capital inflows. Two candidates, one favoring workers and another favoring entrepreneurs, run for office; the winner chooses tax policy, which affects investment returns. A pro labor electoral victory results in a "sudden stop" in investment and capital flows, reflecting a time inconsistency problem. While th...

Lada et al. recently presented a detailed near-infrared extinction map of Globule G2 in the Coalsack molecular cloud complex, showing that this starless core has a well-defined central extinction minimum. We propose a model for G2 in which a rapid increase in external pressure is driving an approximately symmetric compression wave into the core. The rapid increase in external pressure could ari...

The first annual meeting of Deputy Governors from the emerging markets took place at the BIS in February 1995. It had as its central focus the challenge to central banks (and supervisors) as countries moved towards a more liberal banking system in the context of wider capital account convertibility. There was at that meeting a common sense of unease about short-term capital flows, a good deal o...

Application of compression stockings to the lower extremities is a widely used therapeutic intervention to improve venous return, but there is little information about the effects of compression on local arterial perfusion. Therefore, we tested the hypothesis that a positive external pressure increases forearm perfusion. The relation of increasing external pressure induced by standardized compr...

This study is based on analysis of copyright policies and 26 interviews with science and engineering faculty at three research universities on the topic of copyright beliefs, values, and practices, with emphasis on copyright of instructional materials, courseware, tools, and texts. Given that research universities now emphasize increasing external revenue flows through marketing of intellectual...

We consider a class of continuous-time hybrid dynamical systems that correspond to subgradient flows of a piecewise linear and convex potential function with finitely many pieces, and which include the fluid-level dynamics of the Max-Weight scheduling policy as a special case. We study the effect of an external disturbance on the state trajectory, and establish that the magnitude of this effect...

For some time now, I have been hearing of a mythical place where quite impossible things seem to happen. It is a country the size of a continent, but with a small and very open economy that allows its currency to fluctuate to the tune of its quite erratic terms of trade. It can do so without kindling fears of inflation or wreaking havoc on bond prices. It is a country where short-term interest ...

We first study the characteristics of the crisis and its impacts on Taiwanese and Korean economies. We have examined 22 macroeconomic fundamentals, such as inflation rates, government budget, trade balance, external debt, money supply, and ratios of average monthly imports and cumulative inward portfolio investment to international reserves, and compared with an extensive data set of the two co...
