... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...

I would like to propose two new features for the axes annotation in the GMT. 1st: In astrophysics, we often work with great ranges of values (many orders of magnitude). ... However, GMT 3.2 allows to plot annotations for log10 axes every integer log10 value or even more frequently. The proposed patch allows to specify large steps for the log10 axes, in the form illustrated by an example below. 2nd: 10^0 instead of 1, and 10^1 instead of simply 10 do not look beautiful. ... The patch is here. ...

... We have observed and studied critical supercurrents, Ic, in cross-type Nb-Cu/Ni-Nb junctions with Josephson layers prepared from diluted ferromagnetic alloys. For suitable values of the exchange energy in the ferromagnet and the F-layer thickness we have observed Ic(T) oscillation with vanishing Ic for the definite values of T and dF. ... Critical supercurrents, Ic, in Nb-Cu(1-x)Ni(x)-Nb Josephson SFS junctions with F-layers prepared from ferromagnetic Cu(1-x)Ni(x) alloys have been studied. ...

... Future seminars . ... Nonlinear theory of mirror (diamagnetic) instability near its excitation threshol d " . ... It is demonstrated that near threshold of mirror instability the main contribution to the quadratic nonlinearity is connected with perpendicular pressure. We derive the three-dimensional equation which describes the weakly nonlinear behavior of the system. ... As a consequence the corresponding free energy decreases in time providing a blow-up appearance of magnetic holes. ...

Recent evidence suggests that the Universe is filled with something termed "Dark Energy". ... Baryons are normal particles (e.g. protons and neutrons) which make up all of ordinary matter. ... What are some resolutions to this problem and how do "Low Surface Brightness Galaxies" fit in to the problem of missing baryons. ... In this exercise, you will use a computational engine to model two interacting galaxies to see if you can reproduce the observed morphology of two real systems. ...
