... I study algebraic transformation groups, toric varieties, linear algebraic groups and their representations, invariant theory, Lie groups and Lie algebras. Specific sub jects are algebraic homogeneous spaces and their embeddings, Cox rings, T -varieties, combinatorial methods of geometric invariant theory, and automorphisms of algebraic varieties. ... Study of algebraic varieties equipped with a regular action of an algebraic torus T is a classical topic in algebraic geometry. ...

... High-pressures experiments are mostly aimed at studying phase transformations in solids, synthesising new phases and studying their composition, crystal and magnetic structure, physical and thermodynamical properties. ... The specific feature of investigations at LHPP that distinguishes it from most other high-pressure laboratories is combining in situ measurements with studies at ambient pressure of new high-pressure phases fixed by quenching to liquid nitrogen temperature. ...

... Archives . ... keV vs keV [Eqn] . ... As mentioned before, background subtraction plays a big role in astrophysical analyses. For a variety of reasons, it is not a good idea to subtract out background counts from source counts, especially in the low-counts Poisson regime. What Bayesians recommend instead is to set up a model for the intensity of the source and the background and to infer these intensities given the data. ... C = Poisson(? ... Chandra Blog . ...

... We have developed a set of tasks in the IRAF environment for registering, matching the point-spread functions, and matching the intensity scales of two or more images. ... The current software performs spatial registration by supplying the registration task with a reference and input image list, and a list of features common to both images. ... The current software requires the input and reference images to be spatially-registered and PSF-matched. ... CTIO 4-m images courtesy of Nelson Calwell.) ...
