The algorithm described reconstructs a set of topological vertices each associated with an independent subset of the charged tracks in a hadronic jet. Vertices are reconstructed by associating tracks with 3D spatial regions according to a vertex probability function which is based on the trajectories and position resolution of the tracks. SLD data is used to illustrate the performance of the al...

By the use of Cr-39 particle track detectors immersed in the electrolyte, we confirm that a nuclear reaction of as-yet unknown nature can take place during electrolysis. With Li2SO4 dissolved in D2O or H2O and either Pd or Ni as cathodes, a very large statistical difference in nuclear track generation is found between detector chips immersed during electrolysis and the control chips immersed in...

This paper reviews some aspects of solid-state nuclear track detectors (SSNTDs) and their applications in the radon and other research fields. Several geometrical models for the track growth given in the literature are described and compared. It is found that different models give close results for the dimensions of track openings. One of the main parameters that govern track formation is the b...

The GTPase Ran is best known for its crucial roles in the regulation of nucleocytoplasmic transport in interphase cells and in the organization of the spindle apparatus during mitosis. A flurry of recent reports has now implicated Ran in diverse cytoplasmic events, including trafficking of an ephrin receptor homolog in nematode oocytes, control of neurite outgrowth in Drosophila and mammalian n...

A challenging task in the application of solid-state nuclear track detectors (SSNTDs) is the measurement of depths of the tracks. One approach involves breaking and polishing the side of SSNTDs to reveal the cross-sections of the tracks for direct measurements. Recently, surface profilometry was used to measure the heights of the replicas of alpha-particle tracks to give the track depths. In th...

A confocal scanner for selective observation of the vertical particle tracks in the nuclear photoemulsion is described. The particle track being searched for is imaging at an angle of 45◦ with respect to the optical axis of the system. The confocal scanner is provided with a new optical element, an ®image orthogonalizator ̄, by means of which the extended image of the inclined vertical particle ...

The possibility of a three-dimensional visualisation/reconstruction of tracks in nuclear emulsion films using X-ray imaging is described in this paper. The feasibility of the technique is established with experimental results.
