purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

The Hamiltonian formulation for perfect fluid equations with the ℓ-conformal Galilei symmetry is proposed. For an arbitrary half-integer value of parameter ℓ, Hamilton and non-canonical Poisson brackets are found, in terms which original higher derivative motion take conventional form. full set conserved charges found their algebra established.

The issue of constructing N=1,2,3 supersymmetric extensions the l-conformal Galilei algebra is reconsidered following approach in [JHEP 1709 (2017) 131]. Drawing a parallel between acceleration generators entering superalgebra and irreducible supermultiplets d=1, N-extended superconformal group, new N=1 superalgebra, two N=2 variants, N=3 versions are built. Realisations terms differential oper...
