Sign-symmetry of temperature structure functions

Sign-symmetry of temperature structure functions.

New scalar structure functions with different sign-symmetry properties are defined. These structure functions possess different scaling exponents even when their order is the same. Their scaling properties are investigated for second and third orders, using data from high-Reynolds-number atmospheric boundary layer. It is only when structure functions with disparate sign-symmetry properties are ...

Chiral Symmetry and the Nucleon Structure Functions

The flavor asymmetry of the sea quark distribution as well as the unexpectedly small quark spin fraction of the nucleon are two outstanding discoveries recently made in the physics of deep-inelastic structure functions. We evaluate here the corresponding quark distribution functions within the framework of the chiral quark soliton model, which is an effective quark model of baryons maximally in...

Symmetry-broken crystal structure of elemental boron at low temperature

The crystal structure of boron is unique among chemical elements, highly complex, and imperfectly known. Experimentalists report that the -rhombohedral black form is stable over all temperatures from absolute zero to melting. However, early calculations found its energy to be greater than the energy of the -rhombohedral red form, implying that the phase cannot be stable at low temperatures. Fur...

Symmetry Classes of Alternating Sign Matrices

An alternating sign matrix is a square matrix satisfying (i) all entries are equal to 1, −1 or 0; (ii) every row and column has sum 1; (iii) in every row and column the non-zero entries alternate in sign. The 8-element group of symmetries of the square acts in an obvious way on square matrices. For any subgroup of the group of symmetries of the square we may consider the subset of matrices inva...
