AAPM Task Group 298: Recommendations on certificate program/alternative pathway candidate education and training

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Entry into the field of clinical medical physics is most commonly accomplished through the completion of a Commission on Accreditation of Medical Physics Educational Programs (CAMPEP)‐accredited graduate and residency program. To allow a mechanism to bring valuable expertise from other disciplines into clinical practice in medical physics, an “

Further results on a space-time FOSLS formulation of parabolic PDEs [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 55 (2021), 283-299, 2020
In [2019, Space-time least-squares finite elements for parabolic equations, arXiv:1911.01942] by F\"uhrer& Karkulik, well-posedness of a space-time First-Order System Least-Squares formulation of the heat equation was proven. In the present work, this result is generalized to general second order parabolic PDEs with possibly inhomogenoeus boundary ...

A step-by-step tutorial on active inference and its application to empirical data

open access: yesJournal of Mathematical Psychology, 2021
The active inference framework, and in particular its recent formulation as a partially observable Markov decision process (POMDP), has gained increasing popularity in recent years as a useful approach for modeling neurocognitive processes.

Age- and bite-structured models for vector-borne diseases

open access: yesEpidemics, 2015
The biology and behaviour of biting insects is a vitally important aspect in the spread of vector-borne diseases. This paper aims to determine, through the use of mathematical models, what effect incorporating vector senescence and realistic feeding ...

Task-Driven Adaptive Statistical Compressive Sensing of Gaussian Mixture Models [PDF]

open access: yes, 2012
A framework for adaptive and non-adaptive statistical compressive sensing is developed, where a statistical model replaces the standard sparsity model of classical compressive sensing.

The Rate-Controlled Constrained-Equilibrium Approach to Far-From-Local-Equilibrium Thermodynamics

open access: yesEntropy, 2012
The Rate-Controlled Constrained-Equilibrium (RCCE) method for the description of the time-dependent behavior of dynamical systems in non-equilibrium states is a general, effective, physically based method for model order reduction that was originally ...

Eulerian-Lagrangian Analysis of Multiphase Flow in Urea Prilling Process with Phase Changing

open access: yesChemical Engineering Transactions, 2013
The objective of this work is the mathematical formulation of a prilling tower taking into account the solidification of the urea droplets, calculated by a shrinking unsolidified core model. The multiphase gas- liquid flow was modelled using the Eulerian-

Exact modifications on a vacuum spacetime due to a gradient bumblebee field at its vacuum expectation value

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
This work belongs to the context of the standard-model extension, in which a Lorentz symmetry violation is induced by a bumblebee field as it acquires a nonzero vacuum expectation value.
