Constraints on the variability of quark masses from nuclear binding
Nuclear binding the light quark heavy nuclei attractive
2014/12/19
Based on recent work on nuclear binding, we update and extend the anthropic constraints on the light quark masses, with results that are more tightly constrained than previously obtained. We find that...
MINIMUM LATENCY LINK SCHEDULING FOR ARBITRARY DIRECTED ACYCLIC NETWORKSUNDER PRECEDENCE AND SINR CONSTRAINTS
Minimum latency link scheduling SINR model physical interference model
2012/12/4
Scheduling wireless links under the SINR model has attracted increasing attention in the past few years [1–6, 8–15, 18–20, 23–25, 27, 28, 33–36, 39, 41, 42, 45, 46]. However, most of previous work did...
PHYSICAL CONSTRAINTS ON THE SIZE AND SHAPE OF MICROALGAE
PHYSICAL CONSTRAINTS SIZE AND SHAPE
2015/11/12
Scaling laws provide a link between biology and physics. They provide a means
by which patterns in biology can be quantified and an explanation from physics can be
correlated with such patterns. I...
Holomorphic Lorentzian Simplicity Constraints
Holomorphic Lorentzian Simplicity Constraints General Relativity and Quantum Cosmology
2011/10/9
Abstract: We develop an Hamiltonian representation of the sl(2,C) algebra on a phase space consisting of N copies of twistors, or bi-spinors. We identify a complete set of global invariants, and show ...
The Dirac Theory of Constraints, the Gotay-Nester Theory and Poisson Geometry
The Dirac Theory of Constraints the Gotay-Nester Theory Poisson Geometry
2011/7/26
Abstract: We present a study of the Dirac theory of constraints emphasizing the duality between the Poisson-algebraic and the geometric points of view, related respectively to the work of Dirac and of...
Classical GR as a topological theory with linear constraints
Classical GR topological theory
2010/12/27
We investigate a formulation of continuum 4d gravity in terms of a constrained topological (BF) theory, in the spirit of the Plebanski formulation, but involving only linear constraints, of the type ...
Scalar models for the generalized Chaplygin gas and the structure formation constraints
Scalar models the generalized Chaplygin gas
2010/12/24
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark energy. It is characterized by a fluid with an equation of state $p = - A/\rho^\alpha$. It can be obtained fro...

Scalar models generalized Chaplygin gas structure formation constraints
2010/12/21
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark
energy. It is characterized by a fluid with an equation of state p = −A/ .
Constraints for the QCD phase diagram from imaginary chemical potential

2011/1/13
We present unambiguous evidence from lattice simulations of Nf = 3 QCD for two tricritical
points in the (T,m) phase diagram at fixed imaginary m/T = ip /3 mod. 2p /3, one in the light
and one in th...
Non-equilibrium steady states : maximization of the Shannon entropy associated to the distribution of dynamical trajectories in the presence of constraints
Non-equilibrium steady states Shannon entropy distribution of dynamical trajectories
2010/11/18
Filyokov and Karpov [Inzhenerno-Fizicheskii Zhurnal 13, 624 (1967)] have proposed a theory of
non-equilibrium steady states in direct analogy with the theory of equilibrium states : the principle is ...
Relativistic Constraints for a Naturalistic Metaphysics of Time
Relativistic Constraints Naturalistic Metaphysics of Time
2010/11/16
The traditional metaphysical debate between static and dynamic views in the philosophy of time is examined in light of considerations concerning the nature of time in physical theory. Adapting the fo...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Cosmology Dark energy -Cosmology theory- Cosmology Observations
2010/12/21
We study cosmological dynamics and late-time evolution of an extended induced grav-ity braneworld scenario. In this scenario, curvature effects are taken into account via the
Gauss-Bonnet term in the...
Strengthening constraints on Yukawa-type corrections to Newtonian gravity from measuring the Casimir force between a cylinder and a plate
Newtonian gravity Casimir force cylinder plate
2010/12/20
We discuss possibility to obtain stronger constraints on non-Newtonian gravity from measuring
the gradient of the Casimir force between a cylinder and a plate. Exact analytical expression
for the Yu...

2010/11/5
For open quantum systems coupled to a thermal bath at inverse temperature $\beta$, it is well known that under the Born-, Markov-, and secular approximations the system density matrix will approach th...

2010/11/11
Measured and calculated cross sections for spin-exchange between alkali atoms and noble gases (specifically sodium and helium) are used to constrain anomalous spin-dependent forces between nuclei at t...
