The physical separation between the LET associated with the ultimate relative biological effect (RBE) and the maximum LET in a proton or ion beam

, 2020
Purpose: To identify the relative positions of the ultimate RBE, at a LET value of LETU (where the LET-RBE turnover point occurs independently of dose), and of the maximum LET (LETM) for a range of ions from protons to Iron ions.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Anti‐TNF‐Alpha Associated Central Nervous System Demyelination. Drug‐Induced Demyelination or Multiple Sclerosis Trigger? A Case Series

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Adalimumab is a monoclonal antibody that targets TNF‐α and is effective in treating several autoimmune disorders, including non‐infectious uveitis; however, it has been associated with demyelinating lesions. This study presents two cases of CNS demyelination in patients who consumed adalimumab. First, an 18‐year‐old man presented with subacute
