By sequencing tens of millions of TCRa transcripts from naive mouse CD8 T cells, Genolet et al (2012) show that the TCRa repertoire is at least as diverse as the TCRb repertoire. This overturns a long held view in the field that recombination of the Tcra locus occurs in a co-ordinate sequential bidirectional manner that relies on proximity of Va and Ja gene segments. The observation that rearra...

To make informed forecasting and replenishment decisions, many companies bring together operational elements of production and distribution with sales and marketing, executing Sales and Operations Planning (S&OP) collaborative improvement processes. As cross-functional and consensus-based processes, S&OP activities create value by keeping supply and demand in balance. But most S&OP arrangements...

In traditional systems engineering (TSE) environments, and particularly in recent years, many are concerned about risk management. So much so that risks are identified early and often, and mitigation techniques are aggressively pursued. In contrast one does not hear as much about opportunity management. What about enterprise systems engineering (ESE) environments? Do traditional methods of hand...

In this paper we consider a block replacement model in which a component can be replaced preventively at maintenance opportunities only. Maintenance opportunities occur randomly and are modelled through a renewal process. In the first, theoretical part of the paper we derive an optimality equation and show that the optimal opportunity block replacement policy can be described as a so-called one...

Evacuation has the potential to save lives, but could be costly in time, money, and credibility. Evacuation is a possible measure in case of a threat for flooding. Different types of evacuation can be distinguished as preventive evacuation, vertical evacuation to safe havens or shelters or shelter in place. The consequences in terms of loss of life depends on the required time related to the ty...

Sri Lanka has a relatively small number of HIV/AIDS cases, but highrisk behaviors that contribute to the spread of the infection are prevalent, making the country highly vulnerable to an AIDS epidemic. Sri Lanka has a narrowing window of opportunity to forestall a largescale epidemic, and the government has requested the World Bank’s help in expanding and strengthening its HIV/AIDS prevention e...

The possibility of using charm meson physics to test the Standard Model (SM) is reviewed. In the case of D0 − D̄0 mixing, the SM contributions are carefully considered and the existence of a window for the observation of new physics is discussed. Some examples of extensions of the SM giving large mixing signals are presented. Finally, some distinctive aspects of CP violation and rare decays in c...
