Nonlinear ionizing radiation-induced changes in eye lens cell proliferation, cyclin D1 expression and lens shape [PDF]

open access: yesOpen Biology, 2015
Elevated cataract risk after radiation exposure was established soon after the discovery of X-rays in 1895. Today, increased cataract incidence among medical imaging practitioners and after nuclear incidents has highlighted how little is still understood

Short-term debt and trade credit: Evidence on a non-linear relationship

open access: yesCogent Economics & Finance, 2021
The literature on the relationship between bank credit and trade credit is mixed between the substitution and complementarity effects. The extant studies only investigate the linear relationship between the two factors, thus missing some important ...

Effect of filler type on non-linear viscoelastic characteristics of asphalt mastic [PDF]

open access: yesArchives of Civil Engineering, 2021
This article discusses the rheological tests and analyses based on the Schapery non-linear viscoelasticity model that were performed to study asphalt mastic behaviour under high shear stresses.

Spatial-Dependent Hamiltonian Formulation of Cross-Mode Modulation

open access: yesIEEE Photonics Journal, 2020
In the absence of random mode mixing (RMM), linearization of the cross-mode modulation (XMM) under pump-probe configuration is in general complicated because the evolution of the pump light depends on the local mode decomposition of itself. In this work,

Non-linear relationships between house size and price

open access: yesInternational Journal of Strategic Property Management, 2021
This study reexamines the relationship between house size and price by using the quantile regression model. Housing transactions data of the National Taipei University Special Zone in Taiwan are adopted, and the findings are as follows.

Effect of slit length on linear and non-linear acoustic transfer impedance of a micro-slit plate

open access: yesActa Acustica, 2022
The effect of the slit length on the acoustic transfer impedance of micro-slit plates (MSPs) is investigated in the linear and non-linear regime for a specific slit geometry.

Comparison of Seven Non-Linear Mixed Effect Model-Based Approaches to Test for Treatment Effect

open access: yesPharmaceutics, 2023
Analyses of longitudinal data with non-linear mixed-effects models (NLMEM) are typically associated with high power, but sometimes at the cost of inflated type I error.

Theoretical Analysis on Reinforced Concrete Bridge from Non-linear Temperature Effect

open access: yesSelected Scientific Papers: Journal of Civil Engineering, 2022
The paper presents a theoretical analysis that models the effects of temperature load induced on a two-pole, twobox reinforced concrete bridge. Implemented was theoretical analysis of thermodynamic effects, which was performed on a closed double-box ...

Genotype Selection for Grain Yield of Sorghum through Generalized Linear Mixed Model

open access: yesAgronomy, 2023
The classical model only provides a correct analysis if all the effects are fixed. For experiments that include fixed and random effects, the general linear mixed model is appropriate for handling the non-normal distributed response variables. The aim of

Lensed CMB power spectra from all-sky correlation functions [PDF]

open access: yes, 2005
Weak lensing of the CMB changes the unlensed temperature anisotropy and polarization power spectra. Accounting for the lensing effect will be crucial to obtain accurate parameter constraints from sensitive CMB observations.
