NewConnect - an alternative platform for new innovative companies

The article discusses the attributes of innovation in the context of creating a knowledge-based economy and presents the alternative stock market NewConnect where the small and medium-sized firms may seek funds to finance their innovative projects. NewConnect's functions and goals are shown with respect to capital circulation, stock market training, education and promotion of SMEs aspiring to enter the Warsaw Stock Exchange in the future, as well as the expansion of the financial infrastructure in Poland and the EU.W artykule zaprezentowano atrybuty innowacyjności w kontekście kreacji Gospodarki Opartej na Wiedzy oraz alternatywny parkiet NewConnect, stanowiący szanse pozyskiwania kapitału na nowatorskie projekty przez małe i średnie firmy. Wskazano na realizowane funkcje i zadania NewConnect w dziele przepływu kapitału, treningu giełdowego, edukacji i promocji małych i średnich spółek aspirujących w przyszłości do zajęcia pozycji na GPW oraz rozbudowy infrastruktury finansowej Polski i Unii Europejskiej

Hyperbolic subdiffusive impedance

We use the hyperbolic subdiffusion equation with fractional time derivatives (the generalized Cattaneo equation) to study the transport process of electrolytes in media where subdiffusion occurs. In this model the flux is delayed in a non-zero time with respect to the concentration gradient. In particular, we obtain the formula of electrochemical subdiffusive impedance of a spatially limited sample in the limit of large and of small pulsation of the electric field. The boundary condition at the external wall of the sample are taken in the general form as a linear combination of subdiffusive flux and concentration of the transported particles. We also discuss the influence of the equation parameters (the subdiffusion parameter and the delay time) on the Nyquist impedance plots.Comment: 10 pages, 5 figure

Time evolution of the reaction front in a subdiffusive system

Using the quasistatic approximation, we show that in a subdiffusion--reaction system the reaction front $x_{f}$ evolves in time according to the formula $x_{f} \sim t^{\alpha/2}$, with $\alpha$ being the subdiffusion parameter. The result is derived for the system where the subdiffusion coefficients of reactants differ from each other. It includes the case of one static reactant. As an application of our results, we compare the time evolution of reaction front extracted from experimental data with the theoretical formula and we find that the transport process of organic acid particles in the tooth enamel is subdiffusive.Comment: 18 pages, 3 figure

Search for a Correlation Between Radio Giant Pulses and VHE Photons of the Crab Pulsar

The Crab pulsar is a unique source of pulsar radio emission. Its regular pulse structure is visible over the entire electromagnetic spectrum from radio to GeV ranges. Among the regular pulses, radio giant pulses (GPs) are known as a special form of pulsar radio emission. Although the Crab pulsar was discovered by its GPs, their origin and emission mechanisms are currently not understood. Within the framework of this report we give a review on radio GPs and present a new idea on how to examine the characteristics of this as yet not understood kind of pulsar emission
