A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
Quantum mechanics modal interpretations relational properties relativity Lorentz invariance
2011/9/7
Recent no go theorems by Dickson and Clifton (1998), Arntzenius (1998) and Myrvold (2002) demonstrate that current modal interpretations are incompatible with relativity. In this paper we propose stra...
High star formation rates as the origin of turbulence in early and modern disk galaxies
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
High spatial and spectral resolution observations of star formation and kinematics in early galaxies have shown that two-thirds are massive rotating disk galaxies with the remainder being less massive...
Statistical mechanics of collisionless orbits. I. Origin of central cusps in dark-matter halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Statistical Mechanics (cond-mat.stat-mech)
2010/12/23
We present an equilibrium statistical mechanical theory of collisionless self-gravitational systems with isotropic velocity distributions.
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...
U-Pb zircon ages of syenitic and granitic rocks in the Ashizuri igneous complex, southwestern Shikoku: Constraint for the origin of forearc alkaline magmatism
U-Pb age zircon LA-ICP-MS Miocene alkaline magmatism Southwest Japan Outer Zone
2017/8/9
We report two first U-Pb zircon ages of the felsic rocks in the Ashizuri igneous complex, southwestern Shikoku, using the LA-ICP-MS. Samples are a syenite (ASH54) and a biotite granite (ASH5). Weighte...
Cultural Communication and Origin of Chinese Alchemy
Cultural Communication Origin of Chinese Alchemy
2014/3/12
This paper discusses a new identification of sources and key components of early Chinese alchemy. All the sources recording early Chinese alchemy could be divided into two sorts, the earlier and the ...
Considering the Mediterranean as a region of high evaporation and low precipitation, evaluations of sinks and sources of moisture and precipitation in the Mediterranean basin have been carried out wit...
Characterising the origin, nature and fate of sediment exported from catchments perturbed by active tectonics
Characterising the origin, nature fate of sediment exported from catchments perturbed active tectonics
2014/5/20
Changes to the tectonic boundary conditions governing erosional dynamics in upland catchments have a significant effect on the nature and magnitude of sediment supply to neighbouring basins. While the...
Challenging US Country of Origin Labelling at the World Trade Organization: The Law, The Issues and The Evidence

2014/4/11
Canada and Mexico are formally challenging US country of origin (COOL) legislation at
the World Trade Organization. The industries most affected by COOL are beef and pork.
The effect of COOL on No...

iving organisms represent
only 1% of all the biota that
has ever existed on earth.
All organisms, living or extinct,
are related to each other by sharing
common ancestors at different levels...
Geometrical origin of chaoticity in the bouncing ball billiard
Geometrical origin ball billiard neighbouring trajectories
2010/4/2
We present a study of the chaotic behavior of the bouncing ball billiard. The work is realised on the purpose of finding at least certain causes of separation of the neighbouring trajectories. Having ...

2014/5/20
A deep low in sea-level pressure is present from May to September over Pakistan and northwestern India (hereafter, the Pak-India low). It is often referred as the "heat" low to convey the significance...

Notes Concerning "On the Origin of Gravity and the Laws of Newton" by E. Verlinde
structure of spacetime partition function phase transition
2010/3/18
We point out that certain equations which, in a very recent paper written by E. Verlinde, are postulated as a starting point for a thermodynamical derivation of classical gravity, are actually consequ...
Common Origin of Soft mu-tau and CP Breaking in Neutrino Seesaw and the Origin of Matter
Soft mu-tau Neutrino Seesaw CP Breaking
2010/3/15
Neutrino oscillation data strongly support mu-tau symmetry as a good approximate flavor symmetry of the neutrino sector, which has to appear in any viable theory for neutrino mass-generation. The mu-t...
