Type IIB GreenSchwarz superstring in plane wave RamondRamond background
 Nucl. Phys. B
"... We construct the covariant κsymmetric superstring action for type IIB superstring on plane wave space supported by RamondRamond background. The action is defined as a 2d sigmamodel on the coset superspace. We fix the fermionic and bosonic lightcone gauges in the covariant GreenSchwarz superstri ..."

Schwarz superstring action and find the lightcone string Lagrangian and the Hamiltonian. The resulting lightcone gauge action is quadratic in both the bosonic and fermionic superstring 2d fields, and therefore, this model can be explicitly quantized. We also obtain a realization of the generators of the basic
Quadratic Actions, Semiclassical Approximation, and Delta Sequences in Gaussian Analysis
, 1998
"... A mathematically rigorous realization of Feynman integrals is given. The construction works for quadratic actions (there is only a restriction to certain time intervals). These techniques enable the calculation of the semiclassical approximation for a given Feynman propagator. Finally, delta sequen ..."

Propagation of Trust and Distrust
, 2004
"... A network of people connected by directed ratings or trust scores, and a model for propagating those trust scores, is a fundamental building block in many of today's most successful ecommerce and recommendation systems. In eBay, such a model of trust has significant influence on the price an i ..."

, and evaluate the schemes on a large trust network consisting of 800K trust scores expressed among 130K people. We show that a small number of expressed trusts/distrust per individual allows us to predict reliably trust between any two people in the system with high accuracy: a quadratic increase in actionable

Learning from demonstration
 Advances in Neural Information Processing Systems 9
, 1997
"... By now it is widely accepted that learning a task from scratch, i.e., without any prior knowledge, is a daunting undertaking. Humans, however, rarely attempt to learn from scratch. They extract initial biases as well as strategies how to approach a learning problem from instructions and/or demonstra ..."

In general nonlinear learning problems, only modelbased reinforcement learning shows significant speedup after a demonstration, while in the special case of linear quadratic regulator (LQR) problems, all methods profit from the demonstration.
