We define a cubical version of categorical group 2-bundles with connection and consider their twodimensional parallel transport with the aim of defining Wilson surface functionals.

We study orbital magnetism of a degenerate electron gas in a number of twodimensional integrable systems, within linear response theory. There are three relevant

We give an automatic method to generate transition matrices associated with twodimensional contraints of finite type by using squared substitutions of constant dimension.

We introduce two models of parallel twodimensional Turing machine with different possibilities of communication among control units and we compare them.

All bialgebra structures on twodimensional Galilei algebra are classified. The corresponding Lie–Poisson structures on Galilei group are found. ∗Supported by the Lódź University Grant No.487

With the rapid development of social economy, people's living standards and quality life are getting better better, food safety is more attention. Aiming at problem vegetable traceability, this paper analyzes bank's QR code scan aggregation payment model. Secondly, it designs a green traceability system elaborates realization main functions system. Practice has proved that can allow consumers t...

The defect investigation of sluice floor is an important measure to ensure the safe operation sluice. due traditional drilling methods will cause damage floor, and appearance inspection compressive strength test can not evaluate internal defects reinforced concrete in floor. In this paper, we apply ground penetrating radar(GPR) quality a gate seawall. And describe layout, detection principle da...

Red cabbage (Brassica oleracea L. Var. Capiata L.) is a fresh edible vegetable abundant in acylated anthocyanins with high antioxidant properties and is a promising resource for the functional food industry. Anthocyanin characterization of red cabbage is not a new topic, but the predominant anthocyanins have been coeluted using high performance liquid chromatography (HPLC) because of their simi...

Spins in semiconductor structures may allow for the realization of scalable quantum bit arrays, an essential component for quantum computation schemes. Specifically, hole spins may be more suited for this purpose than electron spins, due to their strongly reduced interaction with lattice nuclei, which limits spin coherence for electrons in quantum dots. Here, we present resonant spin amplificat...
