Grouped sparse paired comparisons in the Bradley-Terry model

Authors: Ting Yan, Jinfeng Xu, Yaning Yang

arXiv

In a wide class of paired comparisons, especially in the sports games, in which all subjects are divided into several groups, the intragroup comparisons are dense and the intergroup comparisons are sp...

A Unifying Model for the Analysis of Phenotypic, Genetic and Geographic Data

Authors: Gilles Guillot, Sabrina Renaud, Ronan Ledevin, Joahn Michaux, Julien Claude

arXiv

Recognition of evolutionary units (species, populations) requires integrating several kinds of data such as genetic or phenotypic markers or spatial information, in order to get a comprehensive view c...

Generalization of the normal-exponential model: exploration of a more accurate parametrisation for the signal distribution on Illumina BeadArrays

Authors: Sandra Plancade, Yves Rozenholc, Eiliv Lund

arXiv

Motivation: Illumina BeadArray technology includes negative control features that allow a precise estimation of the background noise. As an alternative to the background subtraction proposed in BeadSt...

Scientific Productivity, Research Funding, Race and Ethnicity

Authors: J. S. Yang, M. W. Vannier, F. Wang, Y. Deng, F. R. Ou, J. R. Bennett, Y. Liu, G. Wang

arXiv

In a recent study by Ginther et al., the probability of receiving a U.S. National Institutes of Health (NIH) RO1 award was related to the applicant's race/ethnicity. The results indicate black/African...

Dynamic effective connectivity of inter-areal brain circuits

Authors: Demian Battaglia, Annette Witt, Fred Wolf, Theo Geisel

arXiv

Anatomic connections between brain areas affect information flow between neuronal circuits and the synchronization of neuronal activity. However, such structural connectivity does not coincide with ef...

Variational approximation for mixtures of linear mixed models

Authors: Siew Li Tan, David J. Nott

arXiv

Mixtures of linear mixed models (MLMMs) are useful for clustering grouped data and can be estimated by likelihood maximization through the EM algorithm. The conventional approach to determining a suit...

Evolution of sustained foraging in 3D environments with physics

Authors: Nicolas Chaumont, Christoph Adami

arXiv

Artificially evolving foraging behavior in simulated legged animals has proved to be a notoriously difficult task. Here, we co-evolve the morphology and controller for virtual organisms in a three-dim...

False discovery rates in somatic mutation studies of cancer

Authors: Lorenzo Trippa, Giovanni Parmigiani

arXiv

The purpose of cancer genome sequencing studies is to determine the nature and types of alterations present in a typical cancer and to discover genes mutated at high frequencies. In this article we di...

Causal inference in transportation safety studies: Comparison of potential outcomes and causal diagrams

Authors: Vishesh Karwa, Aleksandra B. Slavković, Eric T. Donnell

arXiv

The research questions that motivate transportation safety studies are causal in nature. Safety researchers typically use observational data to answer such questions, but often without appropriate cau...

Biosensor Arrays for Estimating Molecular Concentration in Fluid Flows

Authors: Maryam Abolfath-Beygi, Vikram Krishnamurthy

arXiv

This paper constructs dynamical models and estimation algorithms for the concentration of target molecules in a fluid flow using an array of novel biosensors. Each biosensor is constructed out of prot...

Cortical phase transitions, non-equilibrium thermodynamics and the time-dependent Ginzburg-Landau equation

Authors: W. J. Freeman, R. Livi, M. Obinata, G. Vitiello

arXiv

The formation of amplitude modulated and phase modulated assemblies of neurons is observed in the brain functional activity. The study of the formation of such structures requires that the analysis ha...

Going off grid: Computationally efficient inference for log-Gaussian Cox processes

Authors: Daniel Simpson, Janine Illian, Finn Lindgren, Sigrunn Sørbye, Håvard Rue

arXiv

This paper introduces a new method for performing computational inference on log-Gaussian Cox processes. The likelihood is approximated directly by making novel use of a continuously specified Gaussia...

A Linear Iterative Unfolding Method

Authors: Andras Laszlo

arXiv

A frequently faced task in experimental physics is to measure the probability distribution of some quantity. Often this quantity to be measured is smeared by a non-ideal detector response or by some p...

Orbital Separation Amplification in Fragile Binaries with Evolved Components

Authors: Kyle B. Johnston, Terry D. Oswalt, David Valls-Gabaud

arXiv

The secular stellar mass-loss causes an amplification of the orbital separation in fragile, common proper motion, binary systems with separations of the order of 1000 A.U. In these systems, companions...
