While a two-dimensional (2D) metallic surface state in bismuth has been proposed, experimental 2D evidence of quantum transport, e.g., angular dependent Shubnikov-de Haas (SdH) oscillations is still lacking. Here, we report the angular-dependent magnetoresistance measurements in single-crystal Bi nanoribbons, and found that both the low-field weak antilocalization behavior and the high-field an...

This paper presents a generalization of the invariant subspace theorem of Helson and Lowdenslager along the lines of de Branges’ generalization of Beurling’s theorem.

The ISLM model has a long, controversial and convoluted history across time and economists. Although often attributed solely to Hicks, and sometimes called the Hicks-Hansen model after Hansen later institutionalised Hicks's formulation within the profession, it would be more accurately called the Harrod-Meade-HicksReddaway-Champernowne-Lange-Timlin-Modigliani-Hansen ISLM model to indicate the b...

We consider a class of fully nonlinear Fermi-Pasta-Ulam (FPU) lattices, consisting of a chain of particles coupled by fractional power nonlinearities of order α>1. This class of systems incorporates a classical Hertzian model describing acoustic wave propagation in chains of touching beads in the absence of precompression. We analyse the propagation of localized waves when α is close to unity. ...

Although important issues are still being investigated today, the bulk of the Fredholm theory of linear elliptic boundary value problems on bounded domains was completed during the 1960s. For pseudodifferential operators, the literature is more recent and begins with the work of Boutet de Monvel 1 ; see also 2 for a more complete exposition. While this was the result of the work and ideas of ma...

OBJECTIVE To evaluate individuals with Cornelia de Lange syndrome previously screened for mutations in the NIPBL gene for genotype-phenotype correlations with regard to severity of ophthalmologic findings. METHODS Fifty-four patients with Cornelia de Lange syndrome (26 mutation positive and 28 mutation negative) with varying extent and severity of ophthalmologic findings participated in the s...
