Reanalyzing production data from three French children, we make three basic points. First, we show that tense and agreement inflection follow independent courses of acquisition (in child French). Tense production starts and ends at near-adult levels, but suffers a “dip” in production at the second stage. Agreement develops linearly, going roughly from none to 100% over the same time. This profi...

A single software fault may cause several tests to break, if they cover the same methods. The coverage sets of tests may not just overlap, but include one another. This information could be of great use to developers who would like to focus on the most specific test that concerns a given fault. Unfortunately, existing unit testing tools neither gather nor exploit this information. We have devel...

Consider a state of a system with several subsystems. The entropies of the reduced state on diierent subsystems obey certain inequalities, provided there is an equivalence relation, and a function measuring volumes or weights of subsystems. The entropy per unit volume or unit weight, the mean entropy, is then decreasing with respect to an order relation of the subsystems, deened in this paper. ...

A new operatilcrnql semantics for *‘pure” CCS is proposed that considers the parallel operator as a first class one, and permits a description of the calculus in terms of partial orderings. The new semantics (also for unguarded agents) is given in the SOS style via the partial ordering derivation relation. CCS agenis are decomposed into sets of sequential subagents. The new derivations relate s...

Electronic and transport properties of Graphene, a one-atom thick crystalline material, are sensitive to the presence of atoms adsorbed on its surface. An ensemble of randomly positioned adatoms, each serving as a scattering center, leads to the Bolzmann-Drude diffusion of charge determining the resistivity of the material. An important question, however, is whether the distribution of adatoms ...
