Uncertainty relations on nilpotent Lie groups
(20170501) 
Uniform asymptotics of areaweighted Dyck paths
(201504) 
Uniform Sampling through the Lovász Local Lemma
(Association for Computing Machinery, 2019)We propose a new algorithmic framework, called `"partial rejection sampling'', to draw samples exactly from a product distribution, conditioned on none of a number of bad events occurring. Our framework builds new connections ... 
An upper bound for topological complexity

Upper Limits on Gravitational Waves from Scorpius X1 from a Modelbased Crosscorrelation Search in Advanced LIGO Data
(IOP Publishing, 20170920)We present the results of a semicoherent search for continuous gravitational waves from the lowmass Xray binary Scorpius X1, using data from the first Advanced LIGO observing run. The search method uses details of the ... 
Using fMRI connectivity to define a treatmentresistant form of posttraumatic stress disorder
(American Association for the Advancement of Science, 20190403)A mechanistic understanding of the pathology of psychiatric disorders has been hampered by extensive heterogeneity in biology, symptoms, and behavior within diagnostic categories that are defined subjectively. We investigated ... 
Using red clump stars to correct the Gaia DR1 parallaxes
(20170201)© ESO 2017. Recent results have suggested that there is tension between the Gaia DR1 TGAS distances and the distances obtained using luminosities determined by eclipsing binaries or asteroseismology on red giant stars. We ... 
Versatility of nodal affiliation to communities

Visibility graphs for fMRI data: Multiplex temporal graphs and their modulations across restingstate networks.
(20171001)Visibility algorithms are a family of methods that map time series into graphs, such that the tools of graph theory and network science can be used for the characterization of time series. This approach has proved a ... 
Visibility graphs for image processing.
(IEEE, 20190109)The family of image visibility graphs (IVG/IHVG) have been recently introduced as simple algorithms by which scalar fields can be mapped into graphs. Here we explore the usefulness of such operator in the scenario of image ... 
Visibility graphs of random scalar fields and spatial data

Waves of Maturation and Senescence in Microstructural MRI Markers of Human Cortical Myelination over the Lifespan.
(20181227)Seminal human brain histology work has demonstrated developmental waves of myelination. Here, using a microstructural magnetic resonance imaging (MRI) marker linked to myelin, we studied finegrained age differences to ...
