c 0000 American Mathematical Society 1052-1798/00 $1.00 + $.25 per page . We present a method for visualising and quantifying the relationship between a pair of gene and species trees that constructs a third tree termed the reconciled tree. Given a gene tree and a species tree the reconciled tree represents the history of the gene tree embedded within the species tree. The reconciled tree is co...

It is proved that all groups of finite U -rank that have the descending chain condition on definable subgroups are totally transcendental. A corollary is that any stable group that is definable in an o-minimal structure is totally transcendental of finite Morley rank. Motivation for this paper is a problem concerning stable groups definable in ominimal structures. One theorem is that any defina...

Fingerprint authentication systems are highly vulnerable to fingerprint artificial reproductions, called presentation attacks. Detecting attacks is not trivial because attackers refine their replication techniques from year year. The International liveness Detection Competition (LivDet), an open and well-acknowledged meeting point of academies private companies that deal with the problem attack...

More than 70 international conference participants attended the workshop on Monday 12th Sept 2005. During that afternoon session, the short lectures of several research groups were presented as listed below. As there was no time left for the discussion on Monday, this was postponed to Tuesday afternoon, 13th Sept 2005. During 70 minutes the points listed below were discussed by more than 30 con...

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 ...
