In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...

New results based on methods of population synthesis, concerning magnetic field effects on the evolution of pulsars are reported. The present study confirms that models with timescales for the magnetic field decay longer than the pulsar lifetime are in better agreement with data. These new simulations indicate that the diagram log(PṖ ) log(ts) alone cannot be used to test field decay models. Th...

It is generally considered as self evident that the lifetime of our vacuum in the landscape of string theory cannot be much shorter than the current age of the universe. Here I show why this lower limit is invalid. A certain type of " parallel universes " is a necessary consequence of the string-landscape dynamics and might well allow us to " survive " vacuum decay. As a consequence our stringy...

In October 2011, we had our 7th General Meeting of the Society in San Diego organized by Guy Salvesen, Matt Bogyo and their colleagues. I would like to thank Matt and Guy on the behalf of the Society for all the hard work it took to organize an excellent meeting and for the great hospitality. You can read more about it in the complete meeting report in this issue. At the Meeting we welcomed Chr...

i We present single photon annihilation results from the MARK II detector at PEP based on 100 pb-l of integrated luminosity taken at a center of mass energy fi = 29 GeV. A study of inclusive leptons for momenta 2 2 GeV/c yield the average semileptonic branching ratios of bottom (b) and charm (c) quarks and information about the b fragmentation function. A measurement of the bottom hadron lifeti...

Temporal events are typically visualized on a time line indicating the date they occurred. This perspective is useful when the questions one wishes to answer are related to the date of occurrence. This view, however, makes it difficult to identify patterns related to the relative duration between events or the sequential order. We demonstrate how the simple notion of temporal alignment by some ...

BACKGROUND TO THE DEBATE Schizophrenia affects an estimated 25 million people in low- and middle-income countries, with an average lifetime risk of about 1%. The illness is associated with excess mortality from a variety of causes. A 2001 Institute of Medicine report on mental illness in developing countries found that in 1990, over two-thirds of people with schizophrenia in these countries wer...

This paper uses theatre to frame reflexive discussions on the use of participatory video making for science engagement. The ‘JuxtaLearn’ research project is presented as a case-study that focuses on performance concepts such as audience, purpose, improvisation or final production as a lens for supporting technology-enabled creative exploration. Three different approaches were taken to creative ...

The recently constructed Dehnen-Binney set of mass models for the Galaxy is used to show that the decaying neutrino theory for the ionisation of the interstellar medium (Sciama 1990a, 1993) requires the neutrino halo of the Galaxy to be as flattened as is observationally permitted (axial ratio q = 0.2 or shape E8). The argument involves an evaluation of the contribution of red-shifted decay pho...

A minimal renormalizable SUSY SO(10) model with B-L symmetry broken by 126 Higgs field has recently been shown to predict all neutrino mixings and the ratio ∆m⊙/∆m 2 A in agreement with observations. Unlike models where B-L is broken by 16 Higgs, this model guarantees automatic R-parity conservation and hence a stable dark matter without any additional symmetry assumptions. In this paper, we di...
