Combined molecular phylogenetic analysis of the Orthoptera (Arthropoda, Insecta) and implications for their higher systematics.
A phylogenetic analysis of mitochondrial and nuclear rDNA sequences from species of all the superfamilies of the insect order Orthoptera (grasshoppers, crickets, and relatives) confirmed thatExpand

Molecular phylogenetic analysis of the Pneumoroidea (Orthoptera, Caelifera): molecular data resolve morphological character conflicts in the basal acridomorpha.
A key transition in the evolution of the insect suborder Caelifera (Orthoptera; Insecta) was from predominantly non-angiosperm-feeding basal lineages to the modern acridomorph fauna (grasshoppers andExpand

SO(3) nonlinear σ model for a spiral phase in the spin-fermion model
Starting from a doped spin-fermion model for the CuO2 planes in high-Tc superconductors, we derive an effective continuum theory for the spin degrees of freedom by means of a gradient expansion. WeExpand
SO(3) nonlinear σ model for a spiral phase in doped antiferromagnets
Abstract Starting from a doped spin-fermion model for the CuO2 planes in high-Tc superconductors, we derive an effective continuum theory for the spin degrees of freedom by means of a gradientExpand

SO (3) nonlinear σ model for a doped quantum helimagnet
Abstract A field theory describing the low-energy, long-wavelength sector of an incommensurate, spiral magnetic phase is derived from a spin-fermion model that is commonly used as a microscopic modelExpand

9. Age Relations of the High Grade Metamorphic Rocks in the Terra Nova Bay Area, North Victoria Land, Antarctica: a Preliminary Report
Samples of high grade metamorphie basement rocks of Wilson Terrane cropping out in the Deep Freeze Range and on Kay Island (Fig, 1) were collected during GANOVEX VI to study their isotopic evolution.Expand

Gradient expansion for a spiral phase in a spin-fermion model
Starting from a doped spin-fermion model for high-temperature superconductors, we derive an effective continuum theory for the spin degrees of freedom by means of a gradient expansion around a spiralExpand
