By using the canonical dual transformation developed recently, we derive a pair of canonical dual problems for 0-1 quadratic programming problems in both minimization and maximization form. Regardless convexity, when the canonical duals are solvable, no duality gap exists between the primal and corresponding dual problems. Both global and local optimality conditions are given. An algorithm is p...

The gap function $\mathrm{\ensuremath{\Delta}}(\ensuremath{\omega})$ carries essential information on both, the pairing glue as well pair-breaking processes in a superconductor. Unfortunately, nearly localized superconductors with nonconstant density of states normal state, standard procedure for extraction cannot be applied. Here we introduce model-independent method that makes it possible to ...

Although some people may develop an intention to change their health behaviour, they might not take any action. This discrepancy has been labelled the "intention-behaviour gap." Detailed action planning, perceived self-efficacy, and self-regulatory strategies (action control) may mediate between intentions and behaviour. This was examined in a longitudinal sample of 307 cardiac rehabilitation p...

The duality theory of the Monge–Kantorovich transport problem is analyzed in a general setting. The spaces X,Y are assumed to be polish and equipped with Borel probability measures μ and ν. The transport cost function c : X × Y → [0,∞] is assumed to be Borel. Our main result states that in this setting there is no duality gap, provided the optimal transport problem is formulated in a suitably r...

A key contribution of this paper is a county-level dataset to study how differences in school quality across locations and races in the South ultimately affected labor market outcomes. Prior to the construction of this data, investigation of this question would have been limited to the use of state-level averages of school quality metrics. These state-level averages are suboptimal for two reaso...

the quantitative relationship between higher education and economic growth in the tradition of “growth accounting equations” and also “neoclassical production function” approach have occupied a pride of place in economics of education, particularly the literature on more developed countries. however, production function type models that allow for isolating the “indirect” (external) effects of h...

in this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for te/tm modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. after that, effects of parameters like...

In a recent Letter, Shen et al 1 have detected a large anisotropy of the superconducting gap in Bi 2 Sr 2 CaCu 2 O 8 (Bi2212), consistent with d-wave symmetry, from photoemission spectroscopy. Moreover, they claim that the change in their spectra as a function of aging is also consistent with such an intrepretation. In this Comment, I show that the latter statement is not entirely correct, in t...
