Cavitation bubbles bursting with cleaning power
Cavitation bubbles bursting cleaning power
2016/1/17
Since prehistoric times, clays have been used by people for medicinal purposes. Whether by eating it, soaking in a mud bath, or using it to stop bleeding from wounds, clay has long been part of keepin...
Discovery about the destructive power of bubbles could lead to new industrial applications

Virginia Tech engineers have shed light on what happens to a nearby particle when bubbles burst.Sunghwan Jung, an assistant professor of biomedical engineering and mechanics in theCollege of Engineeri...
Argonne scientists announce first room-temperature magnetic skyrmion bubbles
Argonne scientists room-temperature magnetic skyrmion bubbles
2015/6/18
New ideas are bubbling up for more efficient computer memory.Researchers at UCLA and the U.S. Department of Energy’s Argonne National Laboratory announced today a new method for creating magnetic skyr...
A common feature of the X-ray bubbles observed in Chandra images of some "cooling flow" clusters is that they appear to be surrounded by bright, cool shells. Temperature maps of a few nearby luminous ...
Recent repeated occurrences of Gas bubbles streaming water jets along Achankovil shear zone of south India and their seismotectonic significance
Achankovil shear zone gas bubbles water jets
2014/11/12
Achankovil shear zone is a major tectonic crustal segment of south India.The recently
observed gas bubbles streaming water jets in the ponds along the shearzone and the minor
tremors released betw...
Champagne subregions with unavoidable bubbles
Champagne subregions unavoidable bubbles Analysis of PDEs
2012/6/29
A champagne subregion of a connected open set $U\ne\emptyset$ in $R^d$, $d\ge 2$, is obtained omitting pairwise disjoint closed balls $\bar B(x, r_x)$, $x\in X$, the bubbles, where $X$ is a locally fi...
X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations
stars: Population III. galaxies: high-redshift. (galaxies:) quasars: general. galaxies: star formation. cosmology: theory. (cosmology:) dark ages, reionization, rst stars
2011/10/9
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light ...

renormalization group, sociophysics, opinion dynamic, finance
2011/8/31
A dynamical model is introduced for the formation of a bullish or bearish trends driving an asset price in a given market. Initially, each agent decides to buy or sell according to its personal opinio...
Nucleation of vacuum bubbles in Brans-Dicke type theory
Nucleation of vacuum Brans-Dicke type theory
2010/12/21
In this paper, we study nucleation of vacuum bubbles in the Brans-Dicke type theory of
gravity. In the Euclidean signatures, we calculate field combinations of vacuum bubbles as
solutions of Einstei...
The Evolution of the Large-scale ISM: Bubbles, Superbubbles and Non-Equilibrium Ionization
the Large-scale ISM Bubbles Superbubbles
2011/1/11
The ISM, powered by SNe, is turbulent and permeated by a magnetic field (with a mean and a turbulent component). It constitutes a frothy medium that is mostly out of equilibrium and is ram pressure do...

Spherical and non-spherical bubbles in cosmological phase transitions
Cosmology and Extragalactic Astrophysics (astro-ph.CO) High Energy Physics - Phenomenology (hep-ph)
2010/12/28
The cosmological remnants of a first-order phase transition generally depend on the perturbations that the walls of expanding bubbles originate in the plasma. Several of the formation mechanisms occur...
Origin and fate of deep-sea seeping methane bubbles at Kuroshima Knoll, Ryukyu forearc region, Japan
thermogenic hydrocarbons methane hydrates carbon isotopes helium isotopes Kuroshima Knoll microbial alteration propane
2017/8/9
Seafloor seeping methane bubbles were successfully sampled on the summit area of the Kuroshima Knoll (depth of ca. 640 m) using the gas-tight sampler WHATS attached to the Shinkai 2000. To evaluate th...
Computational LPPL Fit to Financial Bubbles
LPPL Fit Financial Bubbles log-periodic power law
2010/4/27
The log-periodic power law (LPPL) is a model of asset prices during endogenous bubbles. If the on-going development of a bubble is suspected, asset prices can be fit numerically to the LPPL law. The b...
Risk assessment for uncertain cash flows: Model ambiguity, discounting ambiguity, and the role of bubbles
uncertain cash flows Model ambiguity discounting ambiguity
2010/4/27
We study the risk assessment of uncertain cash flows in terms of dynamic convex risk measures for processes as introduced in Cheridito, Delbaen, and Kupper (2006). These risk measures take into accoun...
