Expression of Biphenyl Synthase Genes and Formation of Phytoalexin Compounds in Three Fire Blight-Infected Pyrus communis Cultivars

Pear (Pyrus communis) is an economically important fruit crop. Drops in yield and even losses of whole plantations are caused by diseases, most importantly fire blight which is triggered by the bacterial pathogen Erwinia amylovora. In response to the infection, biphenyls and dibenzofurans are formed as phytoalexins, biosynthesis of which is initiated by biphenyl synthase (BIS). Two PcBIS transc...

Aram Harrow - Quantum Monte Carlo vs Tunneling in Adiabatic Optimization

In this talk I'll present a quantum algorithm for solving semidefinite programs (SDPs). It has worst case running time O((nm)^1/2 r), with n and r the dimension and sparsity of the input matrices, respectively, and m the number of constraints. In contrast any classical method requires at least Omega(nm) time to solve the problem. I'll discuss how for some instances the algorithm might offer eve...

The PEAR proposition.

For more than a quarter century, the Princeton Engineering Anomalies Research (PEAR) laboratory has engaged in a broad range of experiments on consciousness-related physical anomalies and has proposed a corresponding selection of theoretical models that have combined to illuminate the fundamental nature of the provocative phenomena that emerge. Productive pursuit of this topic has inescapably i...
