Visualizing the logistic map with a microcontroller [PDF]

open access: yes, 2011
The logistic map is one of the simplest nonlinear dynamical systems that clearly exhibit the route to chaos. In this paper, we explored the evolution of the logistic map using an open-source microcontroller connected to an array of light emitting diodes (

Neural networks versus Logistic regression for 30 days all-cause readmission prediction [PDF]

open access: yes, 2018
Heart failure (HF) is one of the leading causes of hospital admissions in the US. Readmission within 30 days after a HF hospitalization is both a recognized indicator for disease progression and a source of considerable financial burden to the healthcare

Bayesian logistic regression for presence-only data [PDF]

open access: yes, 2015
Presence-only data are referred to situations in which a censoring mechanism acts on a binary response which can be partially observed only with respect to one outcome, usually denoting the \textit{presence} of an attribute of interest. A typical example

Interleaving Gains for Receive Diversity Schemes of Distributed Turbo Codes in Wireless Half–Duplex Relay Channels [PDF]

open access: yes, 2015
This paper proposes the interleaving gain in two different distributed turbo-coding schemes: Distributed Turbo Codes (DTC) and Distributed Multiple Turbo Codes (DMTC) for half-duplex relay system as an extension of our previous work on turbo coding ...

Boundedness of classical solutions to a chemotaxis consumption system with signal dependent motility and logistic source

open access: yesComptes Rendus. Mathématique, 2023
We consider the chemotaxis system: \begin{equation*} {\left\lbrace \begin{array}{ll} u_{t}=\nabla \cdot \big (\gamma (v) \nabla u-u \,\xi (v) \nabla v\big )+\mu \, u(1-u), & x\in \Omega , \ t>0, \\ v_{t}=\Delta v-uv, & x\in \Omega , \ t>0, \end{array ...

Automated Lensing Learner: Automated Strong Lensing Identification with a Computer Vision Technique [PDF]

open access: yes, 2019
Forthcoming surveys such as the Large Synoptic Survey Telescope (LSST) and Euclid necessitate automatic and efficient identification methods of strong lensing systems. We present a strong lensing identification approach that utilizes a feature extraction

A further study on an attraction-repulsion chemotaxis system with logistic source

open access: yesAIMS Mathematics
This paper is concerned with the attraction-repulsion chemotaxis system (1.1) define on a bounded domain $ \Omega \subset \mathbb{R}^N(N\geq 1) $ with no-flux boundary conditions.

Sub-logistic source can prevent blow-up in the 2D minimal Keller-Segel chemotaxis system

open access: yes, 2017
It is well-known that the Neumann initial-boundary value problem for the minimal-chemotaxis-logistic system in a 2D bounded smooth domain has no blow-up for any choice of parameters. Here, for a large class of kinetic terms including sub-logistic sources,

Access to Care and Cardiovascular Disease Prevention: A Cross-Sectional Study in 2 Latino Communities. [PDF]

open access: yes, 2015
Cardiovascular disease (CVD) is the leading killer of Americans. CVD is understudied among Latinos, who have high levels of CVD risk factors. This study aimed to determine whether access to health care (ie, insurance status and having a usual source of ...
