Abstract: Gamma-ray imaging attempts to reconstruct the spatial and intensity distribution of gamma-emitting radionuclides from a set of measurements. Generally, this problem is solved by discretizing ...

Hebbian models of development and learning require both activity-dependent synaptic plasticity and a mechanism that induces competition between different synapses. One form of experimentally observed ...

A team of astrophysicists has just published in Nature a finding that calls into question one of the pillars of modern ...

What are each national team’s chances of winning the World Cup? We’ve built a statistical model to try to answer that question rigorously. The model works in two steps: first we measure each team’s ...

For example, Timoshenko theory predicts even slower bending waves than Euler–Bernoulli theory (35), although both beam models agree very closely in our parameter regime. To complete the argument, we ...

Background Difference-in-differences is a method commonly used in population health research. It is based on assumptions that ...
