The Expected Sample Allele Frequencies from Populations of Changing Size via Orthogonal Polynomials

Authors: Lynette Caitlin Mikula, Claus Vogl

arXiv

In this article, discrete and stochastic changes in (effective) population size are incorporated into the spectral representation of a biallelic diffusion process for drift and small mutation rates. A...

Assessing Rate limits Using Behavioral and Neural Responses of Interaural-Time-Difference Cues in Fine-Structure and Envelope

Authors: Hongmei Hu, Stephan Ewert, Birger Kollmeier, Deborah Vickers

arXiv

The objective was to determine the effect of pulse rate on the sensitivity to use interaural-time-difference (ITD) cues and to explore the mechanisms behind rate-dependent degradation in ITD perceptio...

An Explainable Geometric-Weighted Graph Attention Network for Identifying Functional Networks Associated with Gait Impairment

Authors: Favour Nerrise, Qingyu Zhao, Kathleen L. Poston, Kilian M. Pohl, Ehsan Adeli

arXiv

One of the hallmark symptoms of Parkinson's Disease (PD) is the progressive loss of postural reflexes, which eventually leads to gait difficulties and balance problems. Identifying disruptions in brai...

Analyzing time series of unequal durations using Multidimensional Recurrence Quantification Analysis (MdRQA): validation and implementation using Python

Authors: Swarag Thaikkandi, K. M. Sharika

arXiv

In recent years, recurrent quantification analysis (RQA) and its multi-dimensional version (MdRQA) have emerged as a popular tool for assessing interpersonal behavioral or physiological synchrony in g...

Demonstration of a Response Time Based Remaining Useful Life (RUL) Prediction for Software Systems

Authors: Ray Islam, Peter Sandborn

arXiv

Prognostic and Health Management (PHM) has been widely applied to hardware systems in the electronics and non-electronics domains but has not been explored for software. While software does not decay...

Accurate Detection of Spiking Motifs by Learning Heterogeneous Delays of a Spiking Neural Network

Authors: Laurent U Perrinet

arXiv

Recently, interest has grown in exploring the hypothesis that neural activity conveys information through precise spiking motifs. To investigate this phenomenon, various algorithms have been proposed...

Fodor and Pylyshyn's Critique of Connectionism and the Brain as Basis of the Mind

Authors: Christoph von der Malsburg

arXiv

To this day there is no satisfactory answer to the question how mental patterns correspond to physical states of our brain. For more than six decades, progress has been held up by the logjam between t...

Simultaneous embedding of multiple attractor manifolds in a recurrent neural network using constrained gradient optimization

Authors: Haggai Agmon, Yoram Burak

arXiv

The storage of continuous variables in working memory is hypothesized to be sustained in the brain by the dynamics of recurrent neural networks (RNNs) whose steady states form continuous manifolds. In...

Unveil Sleep Spindles with Concentration of Frequency and Time

Authors: Riki Shimizu, Hau-Tieng Wu

arXiv

Objective: Sleep spindles contain crucial brain dynamics information. We introduce the novel non-linear time-frequency analysis tool 'Concentration of Frequency and Time' (ConceFT) to create an interp...

Shorter duration of slow wave sleep is related to symptoms of depression in patients with epilepsy

Authors: Stefanía Eyjolfsdóttir, Eugen Trinka, Yvonne Höller

arXiv

Slow wave sleep duration and spectral abnormalities are related to both epilepsy and depression, but it is unclear how depressive symptoms in patients with epilepsy are affected by slow wave sleep dur...

Fractal Basins as a Mechanism for the Nimble Brain

Authors: Erik Bollt, Jeremie Fish, Anil Kumar, Edmilson Roque dos Santos, Paul J. Laurienti

arXiv

An interesting feature of the brain is its ability to respond to disparate sensory signals from the environment in unique ways depending on the environmental context or current brain state. In dynamic...
