As result of the electronic and atomic collision-cascades close to the ion path a cloud of interstitial atoms and vacancies is formed. At larger distances, the electronic collision-cascade leads to excited atoms and molecules prone to chemical reactions.

The dimensions of latent ion damage tracks
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1984A new model for the formation of ion damage tracks in dielectric solids permits the dimensions of the microscopic structure of the latent tracks to be calculated. In this model the formation of the damage is initiated at separate points along the track by the Auger decay of vacancies produced by the ion in inner electronic shells of atoms of the ...

Subspace Tracking for Latent Semantic Analysis
2011Modern applications of Latent Semantic Analysis (LSA) must deal with enormous (often practically infinite) data collections, calling for a single-pass matrix decomposition algorithm that operates in constant memory w.r.t. the collection size. This paper introduces a streamed distributed algorithm for incremental SVD updates.

Radial dimensions of ion latent tracks in polymers
International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1986Abstract Comparing different experimental results about the dimensions of the ion latent track, we conclude that three zones exist around the ion path. Then we can present a track model which enables us to calculate the core radius r o . The calculated values are in agreement with the experimental ones (electron microscopy, resistivity measures).

Structure and diffusion properties of latent ion tracks
Radiation Effects and Defects in Solids, 1989Abstract Small-angle scattering of x rays and neatrons enables to determine the radial density distribution of latent ion tracks as function of the deposited energy per unit path length. Assuming a Gaussianshape radial defect distribution, the diffusion along latent tracks can be described as a network of interconnected voids.

Tracking Latent Domain Knowledge
2003A common assumption behind measuring the importance of a phenomenon is that the more often a phenomenon is observable, the more important it is likely to be. For example, we tend to think a topic is important if we hear it a lot. In this chapter, we explore the opposite of this assumption.

Structure of Latent Heavy Ion Tracks in Polyimide
Molecular Crystals and Liquid Crystals, 2006ABSTRACT Employing small-angle X-ray scattering, we have confirmed that tracks along wakes of GeV heavy ions in polyimide possess a porous structure. Moreover, specific free volume of ∼ 20 nm3 per nm of track length, independent of track length, has been revealed along 5.5-nm-diameter 25 to 125 μm long tracks created by 2.19 GeV Au ions.

The observation of iron latent tracks in mica muscovite
Radiation Effects, 1979Abstract Latent ion tracks in muscovite are not easily observed by T.E.M. because they fade in the electron beam. For this reason until now, observation of latent tracks by T.E.M. has only been reported for fission fragments in this mineral. In this paper, observation of iron latent tracks in muscovite by T.E.M. is reported.

Polymer chain orientation in latent ion tracks
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1999Abstract The radiolysis products of heavy ion irradiated poly(ethylene terephthalate) (PET) have been studied by means of polarized fluoresence and infrared spectroscopy. The analysis of the polarization spectra reveals that the heavy ion irradiation leads to a molecular orientation in the ion tracks.
