SSRN Electronic Journal, 2015 What risks do asset price bubbles pose for the economy? This paper studies bubbles in housing and equity markets in 17 countries over the past 140 years. History shows that not all bubbles are alike. Some have enormous costs for the economy, while others blow over. We demonstrate that what makes some bubbles more dangerous than others is credit.

Rupture of an air bubble on the solid surfaces
Journal of Fluid Science and Technology, 2018 We investigate behavior of bouncing and rupturing air bubbles on solid surfaces experimentally. We focus our attention to how the hydrophilicity of the solid surface alters the rupture process.

Application of the double optic probe technique to distorted tumbling bubbles in aqueous or organic liquid [PDF]
, 2005 The optic probe technique is widely used to investigate bubble reactors. To derive values of bubble local velocities and bubble local sizes, a specific signal treatment is usually applied under severe assumptions for bubble path and shape.

Behavior of Water Jet Accompanied with Air Suction
Journal of Fluid Science and Technology, 2007 In order to atomize a liquid, the authors have investigated the behavior of air-water jets. In a series of experiments, we have discovered a strange phenomenon that the water jet accompanied with air suction from the free surface has made a periodic ...

Did Bubble Activity Intensify During COVID-19?
, 2020 In this note, we utilize hourly exchange rate data for Japanese Yen, Canadian dollar, European Euro and the British pound to search for possible bubble type behavior. We identify evidence that bubble activity characterizes all four exchange rates more so

Creation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films. [PDF]
Nano letters (Print), 2018 Magnetic skyrmions are topologically nontrivial spin textures which hold great promise as stable information carriers in spintronic devices at the nanoscale. One of the major challenges for developing novel skyrmion-based memory and logic devices is fast
