Linearity and mobility degradation in strained Si MOSFETs with thin gate dielectrics [PDF]

open access: yes, 2010
As gate dielectrics are scaled to a few atomic layers and the channel doping is increased to mitigate short channel effects, high vertical electric fields cause considerable mobility degradation through surface-roughness scattering in silicon MOSFETs ...

Carbon Nanotube Coated Fibrous Tubes for Highly Stretchable Strain Sensors Having High Linearity

open access: yesNanomaterials, 2022
Strain sensors are currently limited by an inability to operate over large deformations or to exhibit linear responses to strain. Producing strain sensors meeting these criteria remains a particularly difficult challenge. In this work, the fabrication of

A Single-Round Infection Fluorescent SARS-CoV-2 Neutralization Test for COVID-19 Serological Testing at a Biosafety Level-2 Laboratory

open access: yesViruses, 2022
A robust serological test to measure neutralizing antibodies against SARS-CoV-2 in biosafety level-2 (BSL-2) laboratories is useful for monitoring antibody response after vaccination or natural infection.

Linear Invariants for Linear Systems

open access: yesCoRR, 2021
A central question in verification is characterizing when a system has invariants of a certain form, and then synthesizing them. We say a system has a $k$ linear invariant, $k$-LI in short, if it has a conjunction of $k$ linear (non-strict) inequalities -- equivalently, an intersection of $k$ (closed) half spaces -- as an invariant.

Approximate entropy as an indicator of non-linearity in self paced voluntary finger movement EEG [PDF]

open access: yes, 2013
This study investigates the indications of non-linear dynamic structures in electroencephalogram signals. The iterative amplitude adjusted surrogate data method along with seven non-linear test statistics namely the third order autocorrelation, asymmetry

Calibration – an under-appreciated component in the analytical process of the medical laboratories

open access: yesAdvances in Laboratory Medicine, 2023
Calibration of an analytical measurement procedure is an important basis for the reliability of patient results. Many publications and as well as procedures on how to estimate quality control and interpret those results have been become available over ...

Non-linearity in experimental journal bearing dynamics - a new approach [PDF]

open access: yes, 2009
This article considers the effects of non-linearity in the dynamic properties of a journal bearing and presents a method of constructing the calculations needed in the identification of a non-linear dynamic model of the oil film.
