Postpartum Psychosis or Something Else?

Psychosis is a psychiatric emergency that affects up to 1 in 500 women postpartum and can result from various etiologies. We present a case vignette and review of the relevant literature to highlight the broad differential diagnosis of postpartum psychosis with atypical features. Recommendations for evaluation, diagnosis, and treatment of patients with complex neuropsychiatric symptoms in the postpartum period are discussed.

Direct growth of monolayer MoS on nanostructured silicon waveguides.

We report for the first time the direct growth of molybdenum disulfide (MoS) monolayers on nanostructured silicon-on-insulator waveguides. Our results indicate the possibility of utilizing the Chemical Vapour Deposition (CVD) on nanostructured photonic devices in a scalable process. Direct growth of 2D material on nanostructures rectifies many drawbacks of the transfer-based approaches.

Brightening of a dark monolayer semiconductor via strong light-matter coupling in a cavity.

Engineering the properties of quantum materials via strong light-matter coupling is a compelling research direction with a multiplicity of modern applications. Those range from modifying charge transport in organic molecules, steering particle correlation and interactions, and even controlling chemical reactions. Here, we study the modification of the material properties via strong coupling and demonstrate an effective inversion of the excitonic band-ordering in a monolayer of WSe with spin-forbidden, optically dark ground state.

Incidental Findings in Head and Brain MRI of Military Pilots and Applicants: Consequences for Medical Flight Fitness.

With improved imaging technology, the number of incidental findings detected in cerebral MRI is increasing. This is a challenge that the German Air Force has to deal with in the context of standardized MRI examinations of young pilot candidates and pilots. The German Air Force Centre of Aerospace Medicine hosted a 2-d conference to develop recommendations and procedures for the handling of some of the most frequently encountered cerebral incidental findings.
