On the mass distribution of neutron stars
The distribution of masses for neutron stars is analyzed using the Bayesian
statistical inference, evaluating the likelihood of proposed gaussian peaks by
using fifty-four measured points obtained in a variety of systems. The results
strongly suggest the existence of a bimodal distribution of the masses, with
the first peak around , and a much wider second peak at . The results support earlier views related to the different
evolutionary histories of the members for the first two peaks, which produces a
natural separation (even if no attempt to "label" the systems has been made
here), and argues against the single-mass scale viewpoint. The bimodal
distribution can also accommodate the recent findings of
masses quite naturally. Finally, we explore the existence of a subgroup around
, finding weak, if any, evidence for it. This recently
claimed low-mass subgroup, possibly related to core collapse events,
has a monotonically decreasing likelihood and does not stand out clearly from
the rest of the sample.Comment: 11 pp., 3 figures, submitted to MNRAS Letter

Polyethylene imine-based receptor immobilization for label free bioassays
Polyethylene imine (PEI) based immobilization of antibodies is described and the concept is proved on the
label free assay of C-Reactive Protein (CRP). This novel immobilization method is composed of a hyperbranched
PEI layer which was deposited at a high pH (9.5) on the sensor surface. The free amino groups
of PEI were derivatized with neutravidin by Biotin N-hydroxysuccinimide ester and the biotinylated
anti-CRP antibody immobilized on this layer. Direct binding assay of recombinant CRP was successfully
performed in the low μg/ml concentrations using a label free optical waveguide biosensor
