Comparing dendritic trees with actual trees

Authors: Roozbeh Farhoodi, Phil Wilkes, Anirudh M. Natarajan, Samantha Ing-Esteves, Julie L. Lefebvre, Mathias Disney, Konrad P. Kording

arXiv

Since they became observable, neuron morphologies have been informally compared with biological trees but they are studied by distinct communities, neuroscientists, and ecologists. The apparent struct...

Linear regression for Poisson count data: A new semi-analytical method with applications to COVID-19 events

Authors: M. Bonamente

arXiv

This paper presents the application of a new semi-analytical method of linear regression for Poisson count data to COVID-19 events. The regression is based on the Bonamente and Spence (2022) maximum-l...

Contemporary climate analogs project north-south polarization of urban water-energy nexus across US cities under warming climate

Authors: Renee Obringer, Roshanak Nateghi, Jessica Knee, Kaveh Madani, Rohini Kumar

arXiv

Despite the coupled nature of water and electricity demand, the two utilities are often managed by different entities with minimal interaction. Neglecting the water-energy demand nexus leads to to sub...

A Note on Bayesian Inference for the Bivariate Pseudo-Exponential Data

Authors: Banoth Veeranna

arXiv

In this present work, we discuss the Bayesian inference for the bivariate pseudo-exponential distribution. Initially, we assume independent gamma priors and then pseudo-gamma priors for the pseudo-exp...

The exploration-exploitation paradigm for networked biological systems

Authors: Vito Dichio, Fabrizio De Vico Fallani

arXiv

The stochastic exploration of the configuration space and the exploitation of functional states underlie many biological processes. The evolutionary dynamics stands out as a remarkable example. Here,...

Global synchronization analysis of non-diffusively coupled networks through Contraction Theory

Authors: Fatou K. Ndow, Zahra Aminzare

arXiv

Synchronization of coupled dynamical systems is a widespread phenomenon in both biological and engineered networks, and understanding this behavior is crucial for controlling such systems. Considerabl...

Bias-Free Estimation of Signals on Top of Unknown Backgrounds

Authors: Johannes Diehl, Jakob Knollmüller, Oliver Schulz

arXiv

We present a method for obtaining unbiased signal estimates in the presence of a significant unknown background, eliminating the need for a parametric model for the background itself. Our approach is...

Social human collective decision-making and its applications with brain network models

Authors: Thoa Thieu, Roderick Melnik

arXiv

In this chapter, we consider probabilistic drift-diffusion models and Bayesian inference frameworks to address this issue, assisting better social human decision-making. We provide details of the mode...
