Can we have many C-sections

Can We Measure Parton - Parton Cross Sections ?

How many positions can we perceptually encode, one or many?

Here we show that our sensitivity for discriminating relative position across the visual field is limited. In experiment 1 we show that we are much worse at detecting a texture defined by the relative position of elements within an array than would be expected if we had access to multiple estimates of relative position across the visual field. In experiment 2 we show that human performance is i...

Sampling and Soundness: Can We Have Both?

Recent research on model counting in CNF formulas has shown that a certain sampling method can yield results that are sound with a provably high probability. The key idea is to iteratively restrict the search space, and to randomly choose which part to consider. The expected value of this sampled count is equal to the real count. If one minimizes over several trials, and purposefully underestim...
