Machine learning assisted masking of parasitic signals in Bragg coherent diffraction imaging

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 448-453, March 2026.
Bragg coherent diffraction imaging measurement sometimes requires manual and time‐consuming cleaning of parasitic signals termed `aliens' from nearby particles that can affect the phase retrieval reconstruction. Here, we propose using a clustering technique to speed up this process while keeping the resolution of the reconstructed object high.

Efficient phase unwrapping

open access: yes, 2005
In the field of optical interferometry, two-dimensional projections of light interference patterns are often analysed in order to obtain measurements of interest. Such interference patterns, or interferograms, contain phase information which is inherently wrapped onto the range -t to it.

Robust phase unwrapping by spinning iteration

open access: yesOptics Express, 2007
This work describes a rapid-phase unwrapping algorithm that combines the rapidity and simplicity of a path-dependent algorithm and the robustness of a path-independent algorithm by rotating the phase map or the unwrapping direction 90 degrees after a scan in one direction. It offers a solution for noise-contaminated phase data, which includes artifacts,

Paramagnetic Rim Lesions in Highly Active Multiple Sclerosis at the Time of Disease Diagnosis: Prevalence Data and Clinical Implications

open access: yesEuropean Journal of Neurology, Volume 33, Issue 3, March 2026.
This prospective cohort study investigated the prevalence, anatomical distribution, and clinical significance of paramagnetic rim lesions (PRLs) in newly diagnosed, treatment‐naïve relapsing multiple sclerosis patients with high disease activity. PRLs were detected on MRI in 76% of patients, mainly in periventricular and juxtacortical regions. Cortical

Personal and relational experiences on meditation journeys following developmental trauma: An IPA study of adults who experienced an inconsistent evolved developmental niche

open access: yesPsychology and Psychotherapy: Theory, Research and Practice, Volume 99, Issue 1, Page 201-218, March 2026.
Abstract Objectives In recent decades, research has increasingly highlighted the devastating effects of childhood trauma and relational processes that violate human development. However, the unique dynamics of such early‐life deprivations in adults who practice meditation, a context where the complexity of such wounding (and healing) may become ...
