Wojcicki and Heyman Respond

Your Data to Explore: An Interview with Anne Wojcicki

How can we not be intrigued by secrets held within our genomes? 23andMe erupted onto the biotech landscape in 2006 to satisfy that curiosity with its promise of genetics fun. For a little bit of spit and a few hundred dollars, we could check out genetic predictions for traits we already know we have—perhaps blonde hair or blue eyes—as well as susceptibilities for diseases we may have yet to dev...

Nightingale and Indekeu respond.

Sense and Respond Systems

The term sense and respond systems has been widely used for some time; see for instance: [Haeckel93, Haeckel99]. A review of government, private and NGO (Non-Governmental Organizational) responses to natural and man-made disasters shows that success in responding to a changing environment depends much more on leadership, organization, and training than on information technology (IT). This paper...

Modified Heyman packing performed with small number of Simon-Norman catheters

PURPOSE Modified Heyman packing method, performed usually with 6-11 flexible catheters is one out of many brachytherapy treatments. We described the insertion and dose planning method, with the use of 4-6 Simon-Norman catheters positioned to the fundus uteri, which is the most frequent source of the endometrial cancer. MATERIAL AND METHODS We investigated the dose distribution of the main cla...

On the Effects of Using the Grassmann-Taksar-Heyman Method in Iterative Aggregation-Disaggregation

Iterative aggregation{disaggregation (IAD) is an eeective method for solving nite nearly completely decomposable (NCD) Markov chains. Small perturbations in the transition probabilities of these chains may lead to considerable changes in the stationary probabilities; NCD Markov chains are known to be ill{conditioned. During an IAD step, this undesirable condition is inherited by the coupling ma...
