A Validated Multiscale In-Silico Model for Mechano-sensitive Tumour Angiogenesis and Growth
(2017)Vascularisation is a key feature of cancer growth, invasion and metastasis. To better understand the governing biophysical processes and their relative importance, it is instructive to develop physiologically representative ...

Vanadium(IV) - Citrate complex interconversions in aqueous solutions. A pH-dependent synthetic, structural, spectroscopic, and magnetic study
(2001)Citrate is abundantly encountered in biological fluids as a natural metal ion chelator. Vanadium participates in biological processes as a catalyst in the active sites of metalloenzymes, as a metabolic regulator, as a ...

Variable property DNS of differentially heated cavities filled with air
(2020)Direct numerical simulations (DNS) of the thermally-driven flow of air inside differentially heated cavities (DHC) are presented. The variation of air properties is taken into account using the low-Mach approximation, to ...

Vascular flow and perfusion imaging with ultrasound contrast agents
(2004)Current techniques for imaging ultrasound (US) contrast agents (UCA) make no distinction between low-velocity microbubbles in the microcirculation and higher-velocity microbubbles in the larger vasculature. A combination ...

Vasodilator-Stimulated Phosphoprotein (VASP) depletion from breast cancer MDA-MB-231 cells inhibits tumor spheroid invasion through downregulation of Migfilin, β-catenin and urokinase-plasminogen activator (uPA)
(2017)A hallmark of cancer cells is their ability to invade surrounding tissues and form metastases. Cell-extracellular matrix (ECM)-adhesion proteins are crucial in metastasis, connecting tumor ECM with actin cytoskeleton thus ...

Very high thermoelectric power factor in a Fe3O4/SiO2/p-type Si(100) heterostructure
(2012)The thermoelectric and transport properties of a Fe3O4/SiO2/p-Si(100) heterostructure have been investigated between 100 and 300 K. Both Hall and Seebeck coefficients change sign from negative to positive with increasing ...

Vibration Measurement of Occupational Exposed Workers, Experimental Quantification of the Individual Response Parameters for the Estimation of Uncertainty in the Vertical Direction
(American Society of Civil Engineers (ASCE), 2014)The exposure of seated people to whole body vibration has been extensively researched and modelled during the past two decades. The trend is to use the average biodynamic responses. This paper investigates the relation of ...

Vortex dynamics below the flux-lattice melting transition in YBa2Cu3O7-
(1995)We report measurements of the critical current, differential resistance, and voltage noise below the vortex-lattice melting transition in clean, untwinned YBa2Cu3O7- crystals. The differential resistance at dc current bias ...

Vortex liquid state in an electron irradiated untwinned YBa2Cu3O7-δ crystal
(1995)We report on the temperature and field dependencies of the resistivity of an untwinned YBa2Cu3O7-δ single crystal before and after 1 MeV electron irradiation in fields up to 8 T. We show, for the first time, direct suppression ...

Vortex shedding lock-on in a periodic freestream flow past a circular cylinder
(Publ by ASME, 1993)Vortex lock-on phenomena in flow past a circular cylinder with a periodic component superimposed on the mean free stream flow is investigated using concepts from dynamical systems (chaos) theory. Numerical results show ...

Vortex-motion-induced voltage noise in YBa2Cu3O7- single crystals
(1995)We have investigated vortex motion below the quasistatic melting transition in a detwinned YBa2Cu3O7- single crystal by measuring the differential resistance and the voltage noise. With the magnetic field parallel to the ...
