Modeling Rasmussen’s dynamic modeling problem: drift towards a boundary of safety

open access: yesCognition, Technology & Work, 2021
We build a system dynamics model based on a conceptual model originally proposed by safety scientist Jens Rasmussen to explore the dynamics of a safety system subject to pressures for performance improvement.

A generalization of Rasmussen’s invariant, with applications to surfaces in some four-manifolds [PDF]

open access: yesDuke mathematical journal, 2019
We extend the definition of Khovanov-Lee homology to links in connected sums of $S^1 \times S^2$'s, and construct a Rasmussen-type invariant for null-homologous links in these manifolds.

Tyrosinase Inhibitors Naturally Present in Plants and Synthetic Modifications of These Natural Products as Anti-Melanogenic Agents: A Review

open access: yesMolecules, 2023
Tyrosinase is a key enzyme target to design new chemical ligands against melanogenesis. In the current review, different chemical derivatives are explored which have been used as anti-melanogenic compounds.

Misdirection due to early magnetoencephalographic presentation and management in Rasmussen encephalitis: a case report

open access: yesFrontiers in Neurology, 2023
Rasmussen encephalitis is a rare and unexplained chronic brain hemispheric inflammatory disease. We report a case of epilepsy in which magnetoencephalography showed dipoles localized only in the operculum.

The radiological presentation of Rasmussen aneurysm secondary to pulmonary tuberculosis and COVID-19: A case report

open access: yesRadiology Case Reports, 2021
Rasmussen aneurysm is rare diagnosis occurring in patients with long-standing tuberculosis. TB-COVID-19 co-infection in the context of Rasmussen aneurysm is a rare occurrence, yet new cases are emerging.

Clinically aggressive pediatric spinal ependymoma with novel MYC amplification demonstrates molecular and histopathologic similarity to newly described MYCN-amplified spinal ependymomas

open access: yesActa Neuropathologica Communications, 2021
Primary spinal cord tumors contribute to ≤ 10% of central nervous system tumors in individuals of pediatric or adolescent age. Among intramedullary tumors, spinal ependymomas make up ~ 30% of this rare tumor population.
