From Gaudin Integrable Models to d-Dimensional Multipoint Conformal Blocks.

In this work, we initiate an integrability-based approach to multipoint conformal blocks for higher-dimensional conformal field theories. Our main observation is that conformal blocks for N-point functions may be considered as eigenfunctions of integrable Gaudin Hamiltonians. This provides us with a complete set of differential equations that can be used to evaluate multipoint blocks.

A facial inflammatory myofibroblastic tumour in a 6-year-old girl: plastic surgery lessons from a rare case.

Inflammatory myofibroblastic tumours (IMT) are rare, challenging lesions with respect to differential diagnosis, biological behaviour and treatment. We reviewed the literature and report a unique case of a large (9 × 8 × 8 cm) IMT in the nasal region of a 6-year-old girl responsible for important facial deformation. Following surgical resection, without any craniofacial reconstruction, the dysmorphism regressed spontaneously with a good result at 2 years of follow-up.
