Suppose there are d diploids and m tetraploids. In the language of [2], there are m models h = 1, h = 2, . . . h = m, where h is the number of hybridizations. Each model has a different number of parameters. Let W be the network topology and node times. The conditional priors π(W |h) must be comparable for different values of h in order to calculate the correct acceptance ratios when jumping be...

The gray filled circle represents the coupling of the virtual photon to the target, taking the target from an initial state X to some final state Y , which we incorporate into a scattering amplitude factor ˆ ν (q), where M q = p − p� = k� − k. The full matrix element for the process is: M = (−ie)ū(p�)γμu(p) −igμν ˆ ν (q) (1) q2 M Parts a) and b) of the problem analyze the structure of the ū(p�)...

Suppose there are d diploids and m tetraploids. In the language of [2], there are m models h = 1, h = 2, . . .h = m, where h is the number of hybridizations. Each model has a different number of parameters. The main difficulty with the network prior is that the normalization constants are needed for the different models. Let W be the network topology and node times. The conditional priors π(W |...

We will report on the IREX (Information Retrieval and Extraction Exercise) project. It is an evaluation-based project for Information Retrieval and Information Extraction in Japanese. The project started in May 1998 and concluded in September 1999 with the IREX workshop held in Tokyo with more than 150 attendance (IREX Commettee, 1999). There is a homepage of the project at (IREX, Homepage) and...

The large-scale applicability of knowledge-based information access systems such as the ones based on Information Extraction techniques strongly depends on the possibility of automatically acquiring the large amount of knowledge required. However, the basic assumption of the IE paradigm, i.e. that the information need is known in advance, limits inherently its applicability since the resulting ...

As a participating national lab in the inter-institutional effort to resolve performance issues of the non-elutable ion exchange technology for Cs extraction, we have carried out a series of characterization studies of UOP IONSIV IE-911 and its component parts. IE-911 is a bound form (zirconium hydroxide-binder) of crystalline silicotitanate (CST) ion exchanger. The crystalline silicotitanate r...

Let G = (V, E) be an interval graph, with 1 VI = n, and IE] = m. An O(n’ log n) algorithm was proposed in Kratsch (Inform Compui. 74, 14O158 (1987)) to find the bandwidth of G. We show that this algorithm is wrong, and provide a corrected version of the same. Also, it was observed in [4] that the bandwidth of a proper inferual graph can be computed in O(n log n + m) time. We show how this idea ...

Charge stripping reactions of the type m• + N--+ m2• + N + ehave been studied for a variety of diatomic and triatomic inorganic and organic ions. Ionisation energies of the m• ions, IE (m+--+ m2• ), have been determined, most of them for the first time. The method is fast and straightforward; it is applicable to both molecular and fragment .ions. The relative cross-sections for the charge strip...

Trimaximal mixing is the mixing hypothesis with maximal symmetry. In trimaximal mixing there remains a still worrying conflict between the large values of ∆m preferred by the atmospheric fits (possibly supported by the early K2K data) and reactor limits on νe-mixing. However, the latest solar results do seem to point to energy-independent (ie. ‘no-scale’) solar solutions, like the trimaximal so...
