OBJECTIVES: To compare bar displacement and complication rates in three retrospective series of patients operated on by the same surgical team. METHOD: A retrospective medical chart analysis of the three patient series was ...

Let G be a group. We give some formulas for the first group homology and cohomology of a group G with coefficients in an arbitrary G-module (Z) over tilde. More explicit calculations are done in the special cases of free ...

It is commonly assumed in the high-resolution sequence stratigraphic analysis ofshallow-marine deposits (e.g., deltaic and shoreface settings) that the depositionalconditions of the system remain relatively constant during ...

We present a study of the excitation conditions and metallicity of ionized gas (Z(gas)) in eight nearby barred and unbarred spiral galaxies from the VIRUS-P Exploration of Nearby Galaxies (VENGA) survey, which provides ...

We construct comparison morphisms between two well-known projective resolutions of a monomial algebra A : the bar resolution Bar A and Bardzell’s resolution Ap A ; the first one is used to define the cup product and the ...

We present a novel interpretation of the previously puzzling different behaviours of stellar populations of the Milky Way's bulge. We first show, by means of pure N-body simulations, that initially co-spatial stellar ...

Bar-trough morphologies are a dominant feature of modern wave-dominated clastic shorelines. Despite thesebarred configurations being widely described from modern systems there is still some uncertainties associatedwith ...
