Abstract Background We report a novel presentation of deficit in anterior pituitary function with variable immune deficiency (DAVID) syndrome in a healthy young girl presenting in Addisonian crisis with raised intracranial pressure. Nearly all cases

By the general theory of PT-symmetric quantum systems, their energy levels are either real or occur in complex-conjugate pairs, which implies that the secular equation must be real. However, for periodic potentials it is by no means clear that the se

The PT symmetric potential V0[cos(2πx/a) + iλ sin(2πx/a)] has a completely real spectrum for λ ≤ 1, and begins to develop complex eigenvalues for λ > 1. At the symmetry-breaking threshold λ = 1 some of the eigenvectors become degenerate, givi

Pseudo-Hermitian quantum theories are those in which the Hamiltonian H satisfies H† = ηHη-1, where η = e-Q is a positive-definite Hermitian operator, rather than the usual H† = H. In the operator formulation of such theories the standard Hilbe

We elucidate the status of the special scattering states found in this paper and explore further the relationships between scattering states and bound states of different non-analytic segments (depending on ∣x∣) of the exponential potential.

In the context of non-Hermitian but PT-symmetric Hamiltonians, we explore the systematics of the coefficients of the multiple commutators that appear in the perturbative expansions for Q, the exponent of the metric operator, and h, the equivalent Her

We use the linear delta expansion with a trial action based on single links to explore the phase structure of the mixedSU(2)-SO(3) lattice gauge theory. The method can be regarded as a systematic expansion going beyond mean field theory or the variat

Recently two variational strategies have been applied to the standard and linear {delta} expansions for quantum field theories. These strategies, both of which improve the accuracy of the expansions, have the property that for {ital N} self-interacti
