Influence of climatic variables on crown condition in pine forests of Northern Spain [PDF]

open access: yes, 2008
Producción CientíficaThe aim of this study was to find relationships between crown condition and some climatic parameters to identify which are those having a main influence on crown condition, and how this influence is shown in the tree (crown ...

Shadows and Twisted Variables [PDF]

open access: yes, 2007
We explain how a new type of fields called shadows and the use of twisted variables allow for a better description of Yang-Mills supersymmetric theories.

Microinertia and internal variables [PDF]

open access: yes, 2015
The origin of microinertia of micromorphic theories is investigated from the point of view of non-equilibrium thermodynamics. In the framework of dual internal variables microinertia stems from a thermodynamic equation of state related to the internal ...

Quantum computation over continuous variables [PDF]

open access: yes, 1998
This paper provides necessary and sufficient conditions for constructing a universal quantum computer over continuous variables. As an example, it is shown how a universal quantum computer for the amplitudes of the electromagnetic field might be ...

Supersymmetry without Grassmann Variables [PDF]

open access: yes, 2001
Supersymmetry transformations may be represented by unitary operators in a formulation of supersymmetry without numbers that anti-commute. The physical relevance of this formulation hinges on whether or not one may add states of even and odd fermion ...

Teleportation of continuous quantum variables [PDF]

open access: yes, 1998
Quantum teleportation is analyzed for states of dynamical variables with continuous spectra, in contrast to previous work with discrete (spin) variables.

Luminosities of AGB Variables [PDF]

open access: yes, 2002
The prevailing evidence suggests that most large-amplitude AGB variables follow the period luminosity (PL) relation that has been established for Miras in the LMC and galactic globular clusters.

The "Dual" Variables Of Yang-Mills Theory And Local Gauge Invariant Variables [PDF]

open access: yes, 1995
After adding auxiliary fields and integrating out the original variables, the Yang-Mills action can be expressed in terms of local gauge invariant variables. This method reproduces the known solution of the two dimensional $SU(N)$ theory.

Bihomogeneous forms in many variables [PDF]

open access: yes, 2013
We count integer points on bihomogeneous varieties using the Hardy-Littlewood method. The main novelty lies in using the structure of bihomogeneous equations to obtain asymptotics in generically fewer variables than would be necessary in using the ...

Denominators of cluster variables

open access: yes, 2007
Associated to any acyclic cluster algebra is a corresponding triangulated category known as the cluster category. It is known that there is a one-to-one correspondence between cluster variables in the cluster algebra and exceptional indecomposable ...
