COUPLED SPIN AND SHAPE EVOLUTION OF SMALL RUBBLE-PILE ASTEROIDS:SELF-LIMITATION OF THE YORP EFFECT
methods numerical–minor planets,asteroids general
2015/12/25
We present the first self-consistent simulations of the coupled spin-shape evolution of small gravitational aggregates under the influence of the YORP effect. Because of YORP's sensitivity to surface ...
Spin-up of rubble-pile asteroids:Disruption,satellite formation,and equilibrium shapes
Asteroid, Dynamics Rotational dynamics Satellites,Dynamics
2015/12/25
We present results from numerical experiments testing the behavior of cohesionless gravitational aggregates experiencing a gradual increase of angular momentum. The test bodies used in these numerical...
A team of Australian researchers used two Maunakea-based observatories – Gemini North and W. M. Keck Observatory – to discover why some galaxies are clumpy rather than spiral in shape and it appears t...
The exploration of eastern Mediterranean deep hypersaline anoxic basins with MODUS: a significant example of technology spin-off from the Geostar Program
deep-sea anoxic basins ROV
2015/9/7
A significant example of technological spin-off from the GEOSTAR project is represented by the special-purpose instrumented module, based on the deep-sea ROV MODUS, which was developed in the framewor...
Exponential error rates in multiple state discrimination on a quantum spin chain
Exponential error rates multiple state discrimination quantum spin chain
2015/8/25
We consider decision problems on finite sets of hypotheses represented by pairwise different shift-invariant states on a quantum spin chain. The decision in favor of one of the hypotheses is based on ...
Transport Patterns of Tropical Reef Fish Larvae by Spin-Off Eddies in the Straits of Florida
Tropical Reef Fish Larvae Spin-Off Eddies Straits of Florida
2015/8/10
Tropical reef fishes belong to a broad phylogenetic group and, as a result, exhibit considerable diversity. Their only shared characteristic as an ecological entity is their fate as reef-associated ad...
Action Potential Modulation of Neural Spin Networks Suggests Possible Role of Spin
Action potential modulation nuclear spin cognitive pixel
2015/7/30
In this paper we show that nuclear spin networks in neural membranes are modulated by action potentials through J-coupling, dipolar coupling and chemical shielding tensors and perturbed by microscopic...
On Dark Chemistry: What’s Dark Matter and How Mind Influences Brain Through Proactive Spin

2015/7/29
Benjamin has written an article entitled “Dark Chemistry or Psychic Spin Pixel?” which promotes a “dark chemistry” model of mind and discuss the spin-mediated theory. This hypothetical chemistry is ba...

Flip-flopping black holes spin end of the dance
2015/4/13
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, said researchers at Rochester Institute of Technology in a paper publi...

Effective Hamiltonian in the Problem of a "Central Spin" Coupled to a Spin Environment
Spin quantum interactive microcosmic spin micro rotation magnetic particles low-energy properties model
2014/12/23
We consider here the problem of a "giant spin", with spin quantum number S≫1, interacting with a set of microscopic spins. Interactions between the microscopic spins are ignored. This model desc...
Systematic 1/M expansion for spin 3/2 particles in baryon chiral perturbation theory
The theory of relativity pion - nucleon - delta system spin 3/2 resonance nuclear soft power the quality of meson
2014/12/22
Starting from a relativistic formulation of the pion-nucleon-delta system, the most general structure of 1/M corrections for a heavy baryon chiral lagrangian including spin 3/2 resonances is given. Th...
Compton scattering and the spin structure of the nucleon at low energies
Compton scattering nuclear scattering the photon energy electron volts baryon chiral perturbation theory
2014/12/22
We analyze polarized Compton scattering which provides information on the spin-structure of the nucleon. For scattering processes with photon energies up to 100 MeV the spin-structure dependence can b...
BPS force balances via spin-spin interactions
BPS soliton static force balance spin quantum mechanics micro sub zero gravity field model
2014/12/22
We study two systems of BPS solitons in which spin-spin interactions are important in establishing the force balances which allow static, multi-soliton solutions to exist. Solitons in the Israel-Wilso...
