In this talk, we present a series of C++ programming design idioms for writing efficient C++ programs, briefly review the underlying C++ object model, and turn to design alternatives when the idioms themselves become overwhelmed with, say, large-scale object creation and copy. We look at object-based and object-oriented design, use of the STL container classes and generic algorithms, and the de...

In the case of oneand two-particle Schrödinger opera tors / / , uppe r bounds on the multiplicity of eigenvalues have been given in [1 4 ] , They generalize results of Birman [5], Schwinger [6], and others (for a review see Simon [7]), who gave global bounds on the n u m b e r of eigenvalues, i.e. bounds on the total n u m b e r of eigenvalues of H below some — x, x positive. Mult ipart icle sy...

A neu/erb B2 ligand growth factor (NEL-GF) was purified to homogeneity from bovine kidney by a procedure involving ammonium sulfate fractionation (35-70% saturation) followed by sequential column chromatography on DEAE-cellulose (DE52), Sulfadex (sulfated Sephadex G-50), heparin-Sepharose 4B, and Superdex 75 (fast protein liquid chromatography). NEL-GF was found to be a 25-kDa polypeptide accor...

T hree large studies in the past 14 months have reopened a longstanding issue in colorectal cancer: Can aspirin prevent it? Or more precisely, is the evidence for preventive benefit in people at average risk strong enough to outweigh the known risks of regular aspirin use? Up to now, the committees that draw up cancer prevention guidelines have concluded that the evidence for aspirin ’ s benefi...

Purpose: This study quantifies uptake of a fluorescent glucose analog, (2-(N-(7-nitrobenz-2oxa-1,3diazol-4-yl)amino)-2-deoxyglucose), (2-NBDG) in a large panel of breast cancer cells and demonstrates potential to monitor changes in glycolysis caused by anticancer and endocrine therapies. Methods: Expressions of glucose transporter (GLUT 1) and hexokinase (HK I), which phosphorylates 2NBDG, were...

We study one-dimensional scattering for a decaying potential with rapid periodic oscillations and strong localized singularities. In particular, we consider the Schrödinger equation Hǫ ψ ≡ ` −∂ x + V0(x) + q (x, x/ǫ) ́ ψ = kψ for k ∈ R and ǫ ≪ 1. Here, q(·, y + 1) = q(·, y), has mean zero and |V0(x) + q(x, ·)| → 0 as |x| → ∞. The distorted plane waves of Hǫ are solutions of the form: eV ǫ±(x; k)...

Biochemical properties of cytosol estrogen receptor (ERC) and nuclear estrogen receptor (ERN) from rat uteri continuously exposed in vivo to 17 beta-[2,4,6,7-3H] estradiol ( [3H]E2) for 6 h have been studied on the basis of immunological recognition and chromatographic elution patterns. Overall concentrations of ERC and ERN did not change during this time period when receptor-saturating concent...

We have previously observed that breast cancer cell lines could exhibit either epithelial or fibroblastic phenotypes as reflected by their morphologies and intermediate filament protein expression (C. L. Sommers, D. Walker-Jones, S. E. Heckford, P. Worland, E. Valverius, R. Clark, M. Stampfer, and E. P. Gelmann, Cancer Res., 49:4258-4263, 1989). Fibroblastoid, vimentin-expressing breast cancer ...
