Fear from the bottom up

Topology from the Bottom Up

evolved to promote and integrate virus production with VS formation. In addition to initiating signal transduc-tion in the infected cell, adhesion molecule engagement at the VS ostensibly activates the uninfected target cell. Activation would ensure expression of virus receptors by the uninfected cell and promote virus replication once the virus has entered its new target. The identity of the H...

Leptogenesis from the bottom-up

In this work we analyze the relevance of the different low energy phases for the CP asymmetry of the Universe. To this end, we develop a parametrization of the see-saw mechanism in terms of low energy data that will allow us to study leptogenesis from a bottom-up perspective. We find that the relevant phases for leptogenesis depend on the particular scenario, and we classify the different possi...

Nanoelectronics from the bottom up.

Electronics obtained through the bottom-up approach of molecular-level control of material composition and structure may lead to devices and fabrication strategies not possible with top-down methods. This review presents a brief summary of bottom-up and hybrid bottom-up/top-down strategies for nanoelectronics with an emphasis on memories based on the crossbar motif. First, we will discuss repre...

Growing Food Safety from the Bottom Up

The overall burden of foodborne illness is unknown, in part because of under-reporting and limited surveillance. Although the morbidity associated with foodborne illness is lower than ever, public risk perception and an increasingly complex food supply chain contribute to uncertainty in the food system. This paper presents an agent-based model of a simple food safety system involving consumers,...
