Full vectorial analysis of polarization effects in optical nanowires [PDF]

, 2012
We develop a full theoretical analysis of the nonlinear interactions of the two polarizations of a waveguide by means of a vectorial model of pulse propagation which applies to high index subwavelength waveguides.

Nonlinear versus Ordinary Adaptive Control of Continuous Stirred-Tank Reactor

The Scientific World Journal, 2015
Unfortunately, the major group of the systems in industry has nonlinear behavior and control of such processes with conventional control approaches with fixed parameters causes problems and suboptimal or unstable control results.

Comparison of Progressive Collapse Capacity of Steel Moment Resisting Frames and Dual Systems with Buckling Retrained Braces [PDF]

Journal of Rehabilitation in Civil Engineering, 2019
Progressive collapse refers to a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently.

Static Nonlinear Analysis Case Study

, 2018
ABSTRACT The goal of this work is to find the displacement demand of structures using nonlinear static procedure, which is intend to provide a simplified approach for direct determination of nonlinear response behavior of a structure at different levels of lateral displacements.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Virtual Testing of Experimental Continuation [PDF]

, 2018
We present a critical advance in experimental testing of nonlinear structures. Traditional quasi-static experimental methods control the displacement or force at one or more load-introduction points on a structure.
