Angiotensin inhibition enhances drug delivery and potentiates chemotherapy by decompressing tumour blood vessels
(2013)Cancer and stromal cells actively exert physical forces (solid stress) to compress tumour blood vessels, thus reducing vascular perfusion. Tumour interstitial matrix also contributes to solid stress, with hyaluronan ...

Anisotropy of the optical dielectric function in the ab plane for YBa2Cu3O7-
(1992)We report ellipsometric measurements from surfaces of three single-crystal samples of YBa2Cu3O7. Two of the samples were untwinned with Tc=90 and 66 K. The third sample was a tetragonal single crystal with low oxygen content ...

Anisotropy of the resistivity in the a-b plane of a superconducting YBa2Cu3O7-δ single crystal
(1996)We have measured the in-plane longitudinal resistivities pa and pb as functions of temperature and magnetic field. The measurements were all made on the same detwinned single crystal of YBa2Cu3O7-δ (YBCO). Defining Tc to ...

Application of a New Algebraic Structure-Based Model to Rotating Turbulent Flows
(Elsevier, 2005)This chapter discusses application of a new algebraic structure-based model to rotating turbulent flows. A primary goal of Reynolds averaged Navier-Stokes (RANS-based modeling is to determine the Reynolds stress tensor in ...

Arc-produced short-length multi-walled carbon nanotubes as “millstones” for the preparation of graphene-like nanoplatelets
(2019)Naturally short-length multi-walled Russian-doll-like carbon nanotubes derived by a catalyst-free arc-discharge method were used as nano-sized “cutters” to transform bulk graphitic sheets into thin/few-layered graphene-like ...

ARPES studies of the superconducting gap in high-temperature superconductors
(Affiliation: Argonne Natl. Lab. and Univ. of, Illinois/Chicago, Chicago, IL, USA, United StatesCorrespondence Address: Ding, H.Argonne Natl. Lab. and Univ. of, Illinois/Chicago, Chicago, IL, USAUnited States, 1996)Using high resolution angle-resolved photoemission spectroscopy (ARPES), we measure the superconducting gap and its momentum dependence in the high temperature superconductors Bi 2Sr 2CaCu 2O 8 (Bi2212) and YBa 2Cu 3O 6.95 ...

ASBM-BSL: An easy access to the structure based model technology
(2011)The Algebraic Structure Based Model (ASBM) offers unique features to represent the Reynolds stress tensor from the underlying turbulent structures. It is usually coupled with a non standard length scale equation. A way of ...

The ASBM-SA turbulence closure: Taking advantage of structure-based modeling in current engineering CFD codes
(2015)Structure-based turbulence models (SBM) carry information about the turbulence structure that is needed for the prediction of complex non-equilibrium flows. SBM have been successfully used to predict a number of canonical ...

Assignment of natural frequencies by an added mass and one or more springs
(2004)The problem of assigning natural frequencies to a multi-degree-of-freedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

Atemplate-based modeling approach for system design: Theory and implementation
(1996)Previous research has developed search algorithms for deducing Proper Models (minimum complexity models with physically meaningful parameters) of dynamic systems. It has also been proposed that these Proper Models can be ...
