Joint Reconstruction via Coupled Bregman Iterations with Applications to PET-MR Imaging [PDF]
Joint reconstruction has recently attracted a lot of attention, especially in the field of medical multi-modality imaging such as PET-MRI. Most of the developed methods rely on the comparison of image gradients, or more precisely their location, direction and magnitude, to make use of structural similarities between the images. A challenge and still an

This study aimed to examine the construct validity of the Arabic version of the behavioral intention to interact with peers using an intellectual disability (ID) scale. Rasch analysis was used to examine the psychometric properties of the scale.

Remarks on the O(N) Implementation of the Fast Marching Method [PDF]
The fast marching algorithm computes an approximate solution to the eikonal equation in O(N log N) time, where the factor log N is due to the administration of a priority queue. Recently, Yatziv, Bartesaghi and Sapiro have suggested to use an untidy priority queue, reducing the overall complexity to O(N) at the price of a small error in the computed ...

Rasch Analysis and Its Relevance to Psychosomatic Medicine
Rasch analysis, an application of item response theory, has been widely applied to the validation of assessment measures, particularly those developed by clinimetric techniques. The main aims of this editorial are to foster further development of valid clinimetric measures by explaining the Rasch method, noting variables generated by Rasch analysis and

Bias-Reduction in Variational Regularization [PDF]
The aim of this paper is to introduce and study a two-step debiasing method for variational regularization. After solving the standard variational problem, the key idea is to add a consecutive debiasing step minimizing the data fidelity on an appropriate set, the so-called model manifold.

Dynamic MRI Reconstruction from Undersampled Data with an Anatomical Prescan [PDF]
The goal of dynamic magnetic resonance imaging (dynamic MRI) is to visualize tissue properties and their local changes over time that are traceable in the MR signal. We propose a new variational approach for the reconstruction of subsampled dynamic MR data, which combines smooth, temporal regularization with spatial total variation regularization.

Development and validation of a conceptual test for the human circulatory system
Current biology assessments often lack a strong emphasis on conceptual understanding, which may limit students' ability to apply knowledge in real-world contexts.
