A novel microfluidic system has been developed that uses the phenomenon of passive pumping along with a user controlled droplet based fluid delivery system. Passive pumping is the phenomenon by which surface tension induced pressure differences drive fluid movement in closed channels. The automated fluid delivery system consists of a set of voltage controlled valves with micro-nozzles connected...

One of the main economic villains before the crisis was the presence of large "global imbalances." The concern was that the U.S. would experience a sudden stop of capital flows, which would unavoidably drag the world economy into a deep recession. However, when the crisis finally did come, the mechanism did not at all resemble the feared sudden stop. Quite the opposite, during the crisis net ca...

The collision of a primordial black hole with neutron star results in the eventually consuming entire star. However, if is magnetically charged, and therefore stable against decay by Hawking radiation, consequences can be quite different. Upon colliding star, magnetic very rapidly comes to stop. For large enough charge, we show that this detected as sudden change rotation period glitch or anti-...

We model sudden stops in a small open economy as rare discrete events precipitated by increases the world risk-free rate. When external debt is large, exhibits multiple equilibria, one where and consumption remain high, with collapse consumption. Private agents delever following an increase interest rate, but they fail to internalize impact of deleveraging on price collateral. For high levels d...

Financial frictions are a central element of most of the models that the literature on emerging markets crises has proposed for explaining the Sudden Stop phenomenon. To date, few studies have aimed to examine the quantitative implications of these models and to integrate them with an equilibrium business cycle framework for emerging economies. This paper surveys these studies, viewing them as ...

BACKGROUND The aim of the present study was to investigate the role of disengagement beliefs in smoking cessation. The association of disengagement beliefs with forward transition through the transtheoretical stages of change and self-reported quitting were examined, with and without adjusting for processes of change. METHODS A longitudinal survey was conducted among Dutch smokers, resulting ...

OBJECTIVE To replicate findings that risk-minimizing and self-exempting beliefs lower quit intentions, and to extend this by testing their capacity to prospectively predict smoking cessation. METHOD 13,324 adult (> or =18 years) cigarette smokers from the USA, Canada, UK, and Australia from one of the first three waves (2002-2004) of the International Tobacco Control 4-Country survey were emp...

The monitoring of machine conditions in a plant is crucial for production manufacturing. A sudden failure can stop and cause loss revenue. vibration signal good indicator its condition. This paper presents dataset signals from lab-scale machine. contains four different types conditions: normal, unbalance, misalignment, bearing fault. Three learning methods (SVM, KNN, GNB) evaluated the dataset,...

We show that the knowledge of time dependent response a trapped gas, subject to sudden rotation confining harmonic potential, allows for determination moment inertia dipolar supersolid configurations. While in presence one-dimensional arrays droplets frequency resulting scissors oscillation provides accurate access value inertia, two-dimensional like configurations are characterized by multi-fr...
