Planck 2013 results. IX. HFI spectral response

The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests was to measure the relative spectral response (including the level of out-of-band signal rejection) of all HFI detectors to a known source of electromagne...

We present an efficient algorithm for the transformation of a Gröbner basis of a zero–dimensional ideal with respect to any given ordering into a Gröbner basis with respect to any other ordering. This algorithm is polynomial in the degree of the ideal. In particular the lexicographical Gröbner basis can be obtained by applying this algorithm after a total degree Gröbner basis computation: it is...

In the majority o f chronic lymphocytic leukemias (CLL), proliferative B lymphocytes are thought to be frozen in vivo at a given maturat ion stage (1). Recently, several studies have emphasized that CLL cells could be driven to different iate into plasma cells in vitro (with or without proliferation) upon t r iggering by mitogens (2, 3, 4) or T cel l -der ived factors (5, 6). Th u s far, howeve...
