Adaptive Model Predictive Control for Cruise Control of High-Speed Trains with Time-Varying Parameters

Journal of Advanced Transportation, 2019
The cruise control of high-speed trains is challenging due to the presence of time-varying air resistance coefficients and control constrains. Because the resistance coefficients for high-speed trains are not accurately known and will change with the ...

Stability of the upwind difference splitting scheme for symmetric t-hyperbolic systems with constant coefficients

Results in Applied Mathematics, 2022
In the paper, we consider a two-hyperbolic system with constant coefficients. Control parameters are entered. We note that coefficients depend on the control parameters. We investigate questions of formulation of mixed problems (problems with initial and

A ‘top‐down’ approach to the determination of control coefficients in metabolic control theory [PDF]

European Journal of Biochemistry, 1990
A new approach to the determination of flux and concentration control coefficients in metabolic pathways is outlined. Linear pathways are conceptually divided in two around an intermediate metabolite (or group of metabolites) and the control coefficients of the two parts are derived from the elasticity coefficients of the two parts to the intermediate.

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

Molecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

Diffusion coefficient measurement using a temperature‐controlled fluid for quality control in multicenter studies [PDF]

Journal of Magnetic Resonance Imaging, 2011
AbstractPurpose:To present the use of a quality control ice‐water phantom for diffusion‐weighted magnetic resonance imaging (DW‐MRI). DW‐MRI has emerged as an important cancer imaging biomarker candidate for diagnosis and early treatment response assessment.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Solvability of an optimal control problem in coefficients for ill-posed elliptic boundary-value problems

Electronic Journal of Differential Equations, 2014
We study an optimal control problem (OCP) associated to a linear elliptic equation $-\hbox{div}(A(x)\nabla y+C(x)\nabla y)=f$. The characteristic feature of this control object is the fact that the matrix $C(x)$ is skew-symmetric and belongs to $
