Apoptosis: Molecular Regulation of Cell Death

Abstract: The field of apoptosis is unusual in several respects. Firstly, its general importance has been widely recognised only in the past few years and its surprising significance is still being evaluated in a number of areas of biology. Secondly, although apoptosis is now accepted as a critical element in the repertoire of potential cellular responses, the picture of the intra-cellular processes involved is probably still incomplete, not just in its details, but also in the basic outline of the process as a whole. It is therefore a very interesting and active area at present and is likely to progress rapidly in the next two or three years.

Music structure and emotional response: Some empirical findings.

Abstract: Eighty-three music listeners completed a questionnaire in which thev provided information about the occurrence of a range of physical reactions while listening to music. Shivers down the spine, laughter, tears and lump in the throat were reported by over 80(% of respondents. Respondents were asked to locate specific musical passages that reliably evoked such responses. Structural analysis of these passages showed that tears were most reliablN evoked by passages containing sequences and appogiaturas, while shivers were most reliably evoked by passages containing new or unexpected harmonies. The data generally support theoretical approaches to elmotion based on confirmations and violations of expectancv.

The Sloan Digital Sky Survey View of the Palomar-Green Bright Quasar Survey

Abstract: We investigate the extent to which the Palomar-Green (PG) Bright Quasar Survey (BQS) is complete and representative of the general quasar population by comparing it with imaging and spectroscopy from the Sloan Digital Sky Survey (SDSS). A comparison of SDSS and PG photometry of both stars and quasars reveals the need to apply a color and magnitude recalibration to the PG data. Using the SDSS photometric catalog, we define the PG's parent sample of objects that are not main-sequence stars and simulate the selection of objects from this parent sample using the PG photometric criteria and errors. This simulation shows that the effective U - B cut in the PG survey is U - B 0.5 are inherently rare in bright surveys in any case). We find no evidence for any other systematic incompleteness when comparing the distributions in color, redshift, and FIRST radio properties of the BQS and a BQS-like subsample of the SDSS quasar sample. However, the application of a bright magnitude limit biases the BQS toward the inclusion of objects that are blue in g - i, in particular compared to the full range of g - i colors found among the i-band limited SDSS quasars, and even at i-band magnitudes comparable to those of the BQS objects.
