Positive definiteness of the blended force-based quasicontinuum method
No full textThe development of consistent and stable quasicontinuum models for multidimensional crystalline solids remains a challenge. For example, proving the stability of the force-based quasicontinuum (QCF) model [M. Dobson and M. Luskin, M2AN Math. Model. Numer. Anal., 42 (2008), pp. 113--139] remains an open problem. In one and two dimensions, we show that by blending atomistic and Cauchy--Born continuum forces (instead of a sharp transition as in the QCF method) one obtains positive-definite blended force-based quasicontinuum (B-QCF) models. We establish sharp conditions on the required blending width
The spectrum of the force-based quasicontinuum operator for a homogeneous periodic chain
No full textWe show under general conditions that the linearized force-based quasicontinuum (QCF) operator has a real, positive spectrum. The spectrum is identical to that of the quasinonlocal quasicontinuum (QNL) operator in the case of second-neighbor interactions. We construct an eigenbasis for the linearized QCF operator whose condition number is uniform in the number of atoms and the size of the atomistic region. These results establish the validity of and improve upon recent numerical observations [M. Dobson, M. Luskin, and C. Ortner, Comput. Methods Appl. Mech. Engrg., 200 (2011), pp. 2697--2709, Multiscale Model. Simul., 8 (2010), pp. 782--802]. As immediate consequences of our results we obtain rigorous estimates for convergence rates of (preconditioned) GMRES algorithms as well as a new stability estimate for the QCF method

Theoretical analysis of dynamic force spectroscopy experiments on ligand-receptor complexes
No full textRaible M, Evstigneev M, Reimann P, Bartels FW, Ros R. Theoretical analysis of dynamic force spectroscopy experiments on ligand-receptor complexes. Journal of Biotechnology. 2004;112(1-2):13-23.The forced rupture of single chemical bonds in biomolecular compounds (e.g. ligand-receptor systems) as observed in dynamic force spectroscopy experiments is addressed. Under the assumption that the probability of bond rupture depends only on the instantaneously acting force, a data collapse onto a single master curve is predicted. For rupture data obtained experimentally by dynamic AFM force spectroscopy of a ligand-receptor bond between a DNA and a regulatory protein we do not find such a collapse. We conclude that the above mentioned, generally accepted assumption is not satisfied and we discuss possible explanations. (C) 2004 Elsevier B.V. All rights reserved

Specific antigen/antibody interactions measured by force microscopy
No full textDammer U, Hegner M, Anselmetti D, et al. Specific antigen/antibody interactions measured by force microscopy. Biophysical journal. 1996;70(5):2437-2441.Molecular recognition between biotinylated bovine serum albumin and polyclonal, biotin-directed IgG antibodies has been measured directly under various buffer conditions using an atomic force microscope (AFM). It was found that even highly structured molecules such as IgG antibodies preserve their specific affinity to their antigens when probed with an AFM in the force mode. Evidence that only a very limited number (less than 10) antibody/antigen pairs contribute to the measured interaction force is given. The potential and limitations of this new approach for the measurement of individual antigen/antibody interactions, and some possible applications are discussed
