Sources of Sex Information Used by Young British Women Who Have Sex with Women (WSW) and Women Who Have Sex Exclusively with Men (WSEM): Evidence from the National Survey of Sexual Attitudes and Lifestyles [PDF]

open access: yes, 2018
There is little consideration about the provision of information about sex to women who have sex with women (WSW). This study drew on data from the third National Survey of Sexual Attitudes and Lifestyle, a nationally representative survey of people in ...

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 (

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 ...

Source Recertification, Refurbishment, and Transfer Logistics [PDF]

open access: yes, 2013
The 2012 Gap Analysis of Department of Energy Radiological Sealed Sources, Standards, and Materials for Safeguards Technology Development [1] report, and the subsequent Reconciliation of Source Needs and Surpluses across the U.S. Department of Energy National Laboratory Complex [2] report, resulted in the identification of 33 requests for nuclear or ...

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

Pattern formation for a nonlinear diffusion chemotaxis model with logistic source

open access: yesBoundary Value Problems, 2018
This paper deals with a Neumann boundary value problem in a d-dimensional box Td=(0,π)d $\mathbb{T}^{d}=(0,\pi)^{d}$ ( d=1,2,3 $d=1, 2, 3$) for a nonlinear diffusion chemotaxis model with logistic source.

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

Long time behavior of the solution to a chemotaxis system with nonlinear indirect signal production and logistic source

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
This paper is devoted to studying the following quasilinear parabolic-elliptic-elliptic chemotaxis system \begin{equation*} \begin{cases} u_{t}=\nabla\cdot(\varphi(u)\nabla u-\psi(u)\nabla v)+au-bu^{\gamma},\ &\ \ x\in \Omega, \ t>0,\\[2.5mm] 0 ...

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 ...
