The name ``tobin'' is obviously derived from ``to binary,'' as in ``convert to binary''. ... If only the name of the input transfer file is provided on the command line, TOBIN will generate a name for the output binary kernel file that has the same base name as the input transfer file and an appropriate filename extension, based on the filename extension of the transfer file. ...

Lucio Piccirillo , T, . тАЬNew Detection Techniques for CMB Polarization ExperimentsтАЭ . Abstract: CMB polarization signals, especially the B-modes, are very weak and usually immersed in several sources of noise, from instrumental to astrophysical. I will briefly review the major experimental issues of CMB polarization measurements with particular emphasis to detectors and optics. A novel scheme for a potential future experiment will be discussed.

... Programme . ... Abstract: We reveal the stellar light originating from the kiloparsec-scale, ring-like structure of the Centaurus A galaxy in unprecedented detail. In particular, we use sub-arcsecond resolution near infrared images to create a dust-free view of this structure that is heavily obscured by the central dust lane at visual wavelengths. ... Finally, we discuss the large-scale geometry implied by the reddening signatures of dust in our near infrared images. go back . ...

Quasi-Hilda Comet 147P/Kushida-Muramatsu: Another long temporary satellite capture by Jupiter . ... The quasi-Hilda comets (QHCs), being in unstable 3:2 Jovian mean motion resonance, are considered a major cause of temporary satellite capture (TSC) by Jupiter. ... Both these numbers rank 147P as third among long TSC/orbiter events, behind SL9 and 111P. This study also confirms the importance of the QHC region as a dynamical route into and out of Jovian TSC, via the Hill's sphere. ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...

... I present results from several seasons of photometric observations of X--ray sources in the Orion OB1a and OB1b star formation regions. The initial goal was to measure the rotational periods of several dozen pre--main sequence (PMS) stars. ... Infrared and optical data confirm that 90% of the X--ray sources are PMS and about 10% of the PMS stars may have disks. ... I find rotation periods for five stars at confidence of greater than 99.9/ greater than 99/ at much lower confidence. ...

Based on a previously compiled catalog of fundamental astrophusical parameters for nearby disk F stars (containing, in particular, metallicity, isochronal ages, and space-velocity components), with were derived from published astrometric data, the Galactic orbital elements were calculated for 1630 stars. ... The radial and vertical metallicity gradients were found for mixed-age stars and for a few narrow age ranges. ...

I consider a special class of singular phenomena: capture into resonance and scaterring on resonance. I particular, I illustrate how the capture into resonance, that by itself is random in nature and, consequently, is rather inefficient as a mechanism of regular transport, can be structured with little additional cost. ...

Titles and abstracts. ... Bernard Leclerc; On the dual canonical basis (old and new) . Around 1991, Lusztig, motivated by earlier works of Gelfand and Zelevinsky, introduced a "canonical basis" of the coordinate ring C[N] of the maximal unipotent subgroup N of a simple algebraic group G. This basis was in fact the specialization as q tends to 1 of the dual canonical basis of the quantum enveloping algebra U_q(n) (where n = Lie(N)). ...
