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...
Explicit Bounds for Entropy Concentration under Linear Constraints
maximum entropy concentration bounds linear constraints tolerances
2011/8/19
Abstract: Consider the construction of an object composed of $m$ parts by distributing $n$ units to those parts. For example, say we are assigning $n$ balls to $m$ boxes. Each assignment results in a ...

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 ...
A One-Dimensional Local Tuning Algorithm for Solving GO Problems with Partially Defined Constraints
Global optimization multiextremal constraints geometric algorithms index scheme local tuning
2011/8/18
Abstract: Lipschitz one-dimensional constrained global optimization (GO) problems where both the objective function and constraints can be multiextremal and non-differentiable are considered in this p...
Univariate global optimization with multiextremal non-differentiable constraints without penalty functions
Global optimization multiextremal constraints Lipschitz functions continuous index functions
2011/8/18
Abstract: This paper proposes a new algorithm for solving constrained global optimization problems where both the objective function and constraints are one-dimensional non-differentiable multiextrema...
Gyromagnetic Factors and Atomic Clock Constraints on the Variation of Fundamental Constants
Gyromagnetic Factors Atomic Clock Constraints Fundamental Constants
2011/8/17
Abstract: We consider the effect of the coupled variations of fundamental constants on the nucleon magnetic moment. The nucleon g-factor enters into the interpretation of the measurements of variation...
On kinematical constraints in fermion-antifermion systems
kinematical constraints fermion-antifermion systems
2011/7/21
We consider the scattering of fermions off antifermions with spin 1/2 and 3/2. Starting from helicity partial-wave scattering amplitudes we derive transformations that eliminate all kinematical constr...

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...

Observational Constraints on Interacting Model of New Agegraphic Dark Energy and Alleviation of Cosmic Age Problem
Observational Constraints on Interacting Model Agegraphic Dark Energy
2010/12/27
Many dark energy models fail to pass the cosmic age test via the old quasar APM 08279+5255 at redshift $z=3.91$, even the $\Lambda$CDM model and the holographic dark energy model are not exception. I...
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 ...
