There is a wide consensus by the research community and the industry that it will not be possible to satisfy future mobile traffic demand and applications’ requirements by simply evolving the current 4G architecture. Instead, there is the need for a considerable revision of the mobile network system: such an effort is commonly referred to as the future “5G architecture”, and large-scale initiat...

This paper shows that income shocks to rural households have permanent effects on the educational attainment of 7-15 year old children within the household. Using a 13 year panel survey of households in rural Tanzania, I find that idiosyncratic crop shocks such as pests, theft and fire cause changes in the distribution of schooling among children within the household that persist 10-13 years af...

Proving the equivalence of successive, closely related versions of a program has the potential of being easier in practice than functional verification, although both problems are undecidable. There are three main reasons for this claim: 1) it circumvents the problem of specifying what the program should do, 2) the problem can be naturally decomposed and hence is computationally easier, and 3) ...

Anewmethod that combines radar reflectivities from individualNextGenerationWeatherRadars (NEXRAD) into a three-dimensional composite with high horizontal and vertical resolution is used to estimate storm-top altitudes for the continental United States east of the RockyMountains. Echo-top altitudes are compared with the altitude of the lapse-rate tropopause calculated from the ERA-Interim reanal...

The NE2001 model for the free electron distribution of the Milky Way includes ad hoc electron “clumps” to reconcile line of sight observables with basic model predictions (Cordes et al. 2002). While MAGPIS (Multi-Array Galactic Plane Imaging Survey) is insensitive to emission from individual diffuse HII regions (ne ∼10 cm), by investigating the 20 cm maps we are able to verify their assumption ...

Information technology today is a complex area, in which new problems and challenges constantly arise and innovations emerge. The ability to incorporate an innovation in time or to solve a problem efficiently can mean competitive advantages for some firms. Being responsive in IT involves being alert, knowledgeable and prepared to face technical problems and to solve them in appropriate ways. In...

We define the notion of a weakly pointed tree, and characterize the amount of genericity necessary to prevent a uniformly branching tree being weakly pointed. We use these ideas to show there is no topological analogue of a measure-theoretic selection theorem of Graf and Mauldin. We consider some topological and recursion-theoretic questions motivated by the following measure-theoretic result o...

Three experiments examined developmental change in children's understanding of regret and relief, two second-order emotions whose quality depends on a comparison between reality and "what might have been." In Experiment 1, participants 7 years of age and older, but not 5-year-olds, made regret-related emotion-response judgments that took into account a comparison of reality with its alternative...

In 3 experiments, the authors examined whether a single act of testimony can inform children's subsequent information seeking. In Experiment 1, participants saw one informant give a correct and another informant give an incorrect answer to a question, assessed who was right (wrong), and decided to whom to address a 2nd question. Adults and 7-year-olds but not 4-year-olds selected the previously...
