Purpose: The range uncertainties in proton therapy is a problem in current treatment planning of cancer, and is largely due to limitations in estimating stopping power (S) from computed tomography (CT) images. With a dual ...

As an attempt to complete black hole thermodynamics, Stephen Hawking showed in 1974 that black holes emit thermal radiation. This result has since been vastly disputed, both because it violates the classical notion that ...

In this thesis, we explore a Bayesian approach to the problem of unfolding, namely Fully Bayesian Unfolding (FBU). With the overarching goal of providing an alternative method to the default unfolding method in use by the ...

There are many complex factors that govern the development of fracture networks and the timing of macroscopic failure in rock. So far, we lack a unifying theory to predict fracture development in heterogeneous rock, and ...

The mystery of dark matter (DM) has intrigued scientists for many decades. The type of DM particles that has been studied the most is Weakly Interacting Massive Particles (WIMPs). These particles are assumed to have been ...
