We present an extension of the “miraculous cancellation” formulas of Alvarez-Gaumé, Witten and Kefeng Liu to a twisted version where an extra complex line bundle is involved. Relations to the Ochanine congruence formula on 8k + 4 dimensional Spinc manifolds are discussed. To cite this article: F. Han, W. Zhang, C. R. Acad. Sci. Paris, Ser.

We refine a result concerning singular matrix pencils and the Wong sequences. In our recent paper [T. Berger and S. Trenn, SIAM J. Matrix Anal. Appl., 33 (2012), pp. 336–368] we have shown that the Wong sequences are sufficient to obtain a quasi-Kronecker form. However, we applied the Wong sequences again on the regular part to decouple the regular matrix pencil corresponding to the finite and ...

The debonding of a thin film, glued to a rigid substratum by a soft adhesive, is known to proceed through the development of a regular array of micro-cavities. We propose a simple model of this phenomenon in the framework of the classical linear fracture mechanics. To cite this article: K.C. Le, L. Truskinovsky, C. R.

The Polycomb group proteins are transcriptional repressors that are thought to act through multimeric nuclear complexes. We show that ph and Psc coprecipitate with Pc from nuclear extracts. We have analyzed the domains required for the association of Psc with ph and Pc by using the yeast two-hybrid system and an in vitro protein-binding assay. Psc and ph interact through regions of sequence con...

We present a new, simple, and inexpensive sandwichtype double-antibody enzyme immunoassay for alpha,antitrypsin in dried blood collected on the fifth day postpartum. The method is very sensitive, having a detection limit of 2.84 fmol/well. Intraand interassay CVs are 6.1% and 10.3%, respectively, for assay of 5-mm-diameter blood spots eluted into 7 mL of phosphate buffer. Since February 1984, w...

I develop theory about two kinds of individual level integration expertise, portable and local. I discuss the implications of the difference between these kinds of expertise for the management of knowledge in complex integrative processes, and for the development of organizational flexibility. I define portable integration expertise as re-deployable from problem to problem, even though the prob...
