New finding shows that males can drive creation of new species
males drive creation new species
2016/2/22
Evolutionary biologists often debate on whether sexual selection can lead to new species. Most studies have focused on natural selection or, for the few studies that considered sexual selection, on ho...
STRATAFORM: A Program to Study the Creation and Interpretation of Sedimentary Strata on Continental Margins
Program Sedimentary Strata
2015/8/13
Continental margins are complex regions of the Earth, because they are the interface between terrestrial and marine environments. Many natural processes occurring on land or in the ocean combine to in...
CREATION OF A HIGH-RESOLUTION PRODUCT CLC2006_BACKDATING BY A BACKWARD LOOK FROM THE DIGITAL LAND COVER MODEL DLM-DE2009 TO 2006 - A CONTRIBUTION TO THE GERMAN CORINE LAND COVER 2012 PROJECT WITHIN A BOTTOM-UP APPROACH
CORINE Land Cover 2012 Backdating Bottom-Up
2015/5/7
For the update 2012 of CORINE Land Cover, in Germany a new approach has been developed in order to profit from the higher accuracies of the national topographic database. In agreement between the Fe...
EXTREME HEAT EVENT RISK MAP CREATION USING A RULE-BASED CLASSIFICATION APPROACH
extreme heat wave vulnerability knowledge-based classification knowledge classifiers expert systems data mining risk mapping maps emergency management
2015/1/9
During a 2011 summer dominated by headlines about an earthquake and a hurricane along the East Coast, extreme heat that silently killed scores of Americans largely went unnoticed by the media and publ...
Pair creation of dilaton black holes
Theory of gravity time and space dimensions coupling a black hole magnetism
2014/12/23
We consider dilaton gravity theories in four spacetime dimensions parametrized by a constant a, which controls the dilaton coupling, and construct new exact solutions. We first generalize the C metric...
Creation of NOON states by double Fock-state/Bose-Einstein condensates
State of single particle state variable theory the measuring accuracy measuring phase the condensate
2014/12/19
NOON states (states of the form |N〉 a |0〉 b +|0〉 a |N〉 b where a and b are single particle states) have been used for predicting violations of hidden-variable theories (Greenbe...
Technique simplifies the creation of high-tech crystals
Technique simplifies creation of high-tech crystals
2014/8/14
Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But ...
The Creation Of Nanometer Magnetic Domain Structure In Artificially Pinning Hole Of Magneto-Optical - Magnetics
Magneto-optical nanometer domain patterned substrate pinned domain
2011/11/30
A novel method for pinning the magnetic domain in artificially pinning hole has been developed for magneto-optical (MO) thin film material.The artificially pinning holes were fabricated using electron...
Creation of Homoclinic Tangencies in Hamiltonians by the Suspension of Poincaré Sections
Hamiltonian vector field Anosov flow elliptic point homoclinic tangency
2011/9/16
Abstract: In this note we show that for any Hamiltonian defined on a symplectic 4-manifold M and any point p in M, there exists a C2-close Hamiltonian whose regular energy surface through p is either ...
The Creation and Propagation of Radiation: Fields Inside and Outside of Sources
The Creation Propagation of Radiation Fields Inside Outside of Sources
2011/8/5
Abstract: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we ...
Non-gaussianities and the Stimulated creation of quanta in the inflationary universe
Non-gaussianities the Stimulated creation
2011/1/11
Cosmological inflation generates a spectrum of density perturbations that can seed the cosmic structures we observe today. These perturbations are usually computed as the result of the gravitationally...
Fields Annihilation and Particles Creation in DBI inflation
Fields Annihilation Particles Creation DBI inflation
2010/12/24
We consider a model of DBI inflation where two stacks of mobile branes are moving ultra relativistically in a warped throat. The stack closer to the tip of the throat is annihilated with the backgroun...
Pilot Wave model that includes creation and annihilation of particles
Pilot Wave model includes creation particles
2010/11/16
The purpose of this paper is to come up with a Pilot Wave model of quantum field theory that incorporates particle creation and annihilation without sacrificing determinism. This has been previously a...
Continuous variables approach to entanglement creation and processing
Continuous variables entanglement squeezed states
2010/11/4
We apply the continuous variable approach to study entangled dynamics of coupled harmonic oscillators interacting with a thermal reservoir and to a deterministic creation of entanglement in an atomic...
