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 ...

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 ...

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 ...

What began with a focus on weather forecasting has evolved toward addressing errors in scientific modeling. In the collaborative environment of the Penn State Institute for Computational and Data ...

This is a 2D orthogonal elliptic mesh (grid) generator which works by solving the Winslow partial differential equations (Elliptic PDEs). It is capable of modifying the meshes with stretching ...

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 ...
