Neural measures of the causal role of observers' facial mimicry on visual working memory for facial expressions

Authors: Paola Sessa, Arianna Schiano Lomoriello, Roy Luria

arXiv

Simulation models of facial expressions propose that sensorimotor regions may increase the clarity of facial expressions representations in extrastriate areas. We monitored the event-related potential...

Discrete structure of the brain rhythms

Authors: Luca Perotti, Justin DeVito, Daniel Bessis, Yuri Dabaghian

arXiv

Neuronal activity in the brain generates synchronous oscillations of the Local Field Potential (LFP). The traditional analyses of the LFPs are based on decomposing the signal into simpler components,...

A New Decision Theoretic Sampling Plan for Exponential Distribution under Type-I Censoring

Authors: Deepak Prajapati, Sharmistha Mitra, Debasis Kundu

arXiv

In this paper a new decision theoretic sampling plan (DSP) is proposed for Type-I censored exponential distribution. The proposed DSP is based on a new estimator of the expected lifetime of an exponen...

Imbalanced Randomization in Clinical Trials

Authors: Thevaa Chandereng, Xiaodan Wei, Rick Chappell

arXiv

Randomization is a common technique used in clinical trials to eliminate potential bias and confounders in a patient population. Equal allocation to treatment groups is the standard due to its optimal...

Fast and Accurate Multiclass Inference for MI-BCIs Using Large Multiscale Temporal and Spectral Features

Authors: Michael Hersche, Tino Rellstab, Pasquale Davide Schiavone, Lukas Cavigelli, Luca Benini, Abbas Rahimi

arXiv

Accurate, fast, and reliable multiclass classification of electroencephalography (EEG) signals is a challenging task towards the development of motor imagery brain-computer interface (MI-BCI) systems....

Bayesian monotonic errors-in-variables models with applications to pathogen susceptibility testing

Authors: Glen DePalma, Bruce A. Craig

arXiv

Drug dilution (MIC) and disk diffusion (DIA) are the two most common antimicrobial susceptibility assays used by hospitals and clinics to determine an unknown pathogen's susceptibility to various anti...

Invertible generalized synchronization: A putative mechanism for implicit learning in biological and artificial neural systems

Authors: Zhixin Lu, Danielle S. Bassett

arXiv

Regardless of the marked differences between biological and artificial neural systems, one fundamental similarity is that they are essentially dynamical systems that can learn to imitate other dynamic...

Online Heart Rate Prediction using Acceleration from a Wrist Worn Wearable

Authors: Ryan McConville, Gareth Archer, Ian Craddock, Herman ter Horst, Robert Piechocki, James Pope, Raul Santos-Rodriguez

arXiv

In this paper we study the prediction of heart rate from acceleration using a wrist worn wearable. Although existing photoplethysmography (PPG) heart rate sensors provide reliable measurements, they u...

On Elo based prediction models for the FIFA Worldcup 2018

Authors: Lorenz A. Gilch, Sebastian Müller

arXiv

We propose an approach for the analysis and prediction of a football championship. It is based on Poisson regression models that include the Elo points of the teams as covariates and incorporates diff...

A Bayesian Penalized Hidden Markov Model for Ant Interactions

Authors: Meridith L. Bartley, Ephraim Hanks, David Hughes

arXiv

Interactions between social animals provide insights into the exchange and flow of nutrients, disease, and social contacts. We consider a chamber level analysis of trophallaxis interactions between ca...

Predicting property damage from tornadoes with zero-inflated neural networks

Authors: Jeremy Diaz, Maxwell Joseph

arXiv

Tornadoes are the most violent of all atmospheric storms. In a typical year, the United States experiences hundreds of tornadoes with associated damages on the order of one billion dollars. Community...

Analyzing Highly Volatile Driving Trips Taken by Alternative Fuel Vehicles

Authors: Mohsen Kamrani, Ramin Arvin, Asad J. Khattak

arXiv

Volatile driving, characterized by fluctuations in speed and accelerations and aggressive lane changing/merging, is known to contribute to transportation crashes. To fully understand driving volatilit...

Exact Combinatorial Inference for Brain Images

Authors: Moo K. Chung, Zhan Luo, Alex D. Leow, Andrew L. Alexander, Richard J. Davidson, H. Hill Goldsmith

arXiv

The permutation test is known as the exact test procedure in statistics. However, often it is not exact in practice and only an approximate method since only a small fraction of every possible permuta...
