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 ...

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

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

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...
