The creation of latent tracks in insulating materials exposed to energetic heavy ions has been studied in a large number of targets. In particular detailed results were obtained in yttrium iron garnet (YIG) Y3Fe5O12 irradiated in a broad range of electronic energy deposition (dE/dx)e both with monoatomic and cluster ions [1-4]. By means of Transmission Electron Microscopy (TEM) and channeling R...

An analytic method for predicting the performance of track-to-track association (TTTA) with biased data in multi-sensor multi-target tracking scenarios is proposed in this paper. The proposed method extends the existing results of the bias-free situation by accounting for the impact of sensor biases. Since little insight of the intrinsic relationship between scenario parameters and the performa...

Many diving animals undergo substantial changes in their body density that are the result of changes in lipid content over their annual fasting cycle. Because the size of the lipid stores reflects an integration of foraging effort (energy expenditure) and foraging success (energy assimilation), measuring body density is a good way to track net resource acquisition of free-ranging animals while ...

Track-oriented multiple hypothesis tracking (MHT) is well-established as a paradigm for multi-sensor multitarget tracking. The fundamental approach includes many variants. Hypothesis-oriented MHT was first proposed by Reid [10]. The initial integer-programming formulation of the problem is due to Morefield [8]. The hybrid-state decomposition that allows for computationally-efficient track-orien...

The SchwartzReport tracks emerging trends that will affect the world, particularly the United States. For EXPLORE it focuses on matters of health in the broadest sense of that term, including medical issues, changes in the biosphere, technology, and policy considerations, all of which will shape our culture and our lives.

In Egypt, girls have traditionally been educationally disadvantaged. This disadvantage, however, has been focused on the failure to enter school. Increasingly it is recognized that girls who ever-enroll are at least as likely to complete primary and secondary education as boys. Still the belief persists that girls, especially those from poor families, will be disadvantaged in terms of school ex...
