Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Does median filtering truly preserve edges better than linear filtering?
, 2009 Image processing researchers commonly assert that "median filtering is better than linear filtering for removing noise in the presence of edges." Using a straightforward large-$n$ decision-theory framework, this folk-theorem is seen to be false in ...

Better than Real: Complex-valued Neural Nets for MRI Fingerprinting
, 2017 The task of MRI fingerprinting is to identify tissue parameters from complex-valued MRI signals. The prevalent approach is dictionary based, where a test MRI signal is compared to stored MRI signals with known tissue parameters and the most similar ...

A little better than placebo is still better than nothing [PDF]
Nature Medicine, 2013 Doctors often dismiss drugs as ineffective if they fail to outperform dummy pills in randomized trials. That's a mistake. When active medicines have few side effects and produce a strong placebo effect, such drugs, even if they prove just slightly better than placebo, should be embraced for the relief they can bring to patients who have few safe ...
