Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials.

Evidence of Involvement of the Calcitonin Gene‐Related Peptide in Restless Legs Syndrome

open access: yesMovement Disorders, EarlyView.
Abstract Background Restless legs syndrome (RLS) is a common sensory‐motor disorder characterized by an urge to move the legs, often with unpleasant sensations, particularly during rest. Current treatments include iron supplementation, dopamine agonists, and opioids, but new therapeutic approaches are needed.

Finding Outliers in Surface Data and Video

open access: yes, 2016
Surface, image and video data can be considered as functional data with a bivariate domain. To detect outlying surfaces or images, a new method is proposed based on the mean and the variability of the degree of outlyingness at each grid point.
