Efficient and fair MAC for wireless networks with self-interference cancellation
tl;dr
We propose ContraFlow, a novel MAC that exploits the benefits of self-interference cancellation and full-duplex in a single band to improve fairness and throughput. Expand

Rethinking Indoor Wireless Mesh Design: Low Power, Low Frequency, Full-Duplex
tl;dr
We propose a novel indoor wireless mesh design paradigm based on Low Frequency, using the newly freed white spaces previously used as analogue TV bands, and Low Power - 100 times less power than currently used. Expand

Bayesian Estimation of Regularization and Atlas Building in Diffeomorphic Image Registration
tl;dr
We develop an atlas estimation procedure that simultaneously estimates the parameters controlling the smoothness of the diffeomorphic transformations and image noise variance. Expand

Efficiency and Fairness in Distributed Wireless Networks Through Self-interference Cancellation and Scheduling
tl;dr
We propose ContraFlow, a solution based on self-interference cancellation and innovative scheduling mechanisms that increases spatial reuse, eliminates hidden terminals, and rectifies decentralized coordination inefficiencies among nodes, thereby improving fairness. Expand

On adaptive-width channel allocation in non-cooperative, multi-radio wireless networks
tl;dr
In this paper, we study the problem of adaptive-width channel allocation from a game-theoretic point of view, in which the nodes are rational and always pursue their own objectives. Expand

A vector momenta formulation of diffeomorphisms for improved geodesic regression and atlas construction
tl;dr
This paper presents a novel approach for diffeomorphic image regression and atlas estimation that results in improved convergence and numerical stability. Expand

Multivariate Statistical Analysis of Deformation Momenta Relating Anatomical Shape to Neuropsychological Measures
tl;dr
We do a global statistical analysis of brain anatomy and identify the relevant shape deformation patterns that explain corresponding variations in clinical neuropsychological measures. Expand

Low-Rank Atlas Image Analyses in the Presence of Pathologies
tl;dr
We present a common framework, for registering images to an atlas and for forming an unbiased atlas, that tolerates the presence of pathologies such as tumors and traumatic brain injury lesions. Expand

Genetic, Structural and Functional Imaging Biomarkers for Early Detection of Conversion from MCI to AD
tl;dr
We evaluate the proposed methodology on the Alzheimer's Disease Neuroimaging Initiative (ADNI) database to predict conversion of individuals with mild cognitive impairment (MCI) to AD, only using information available at baseline. Expand
