This paper concerns the study of the Allee effect on the dynamical behavior of a new class of generalized logistic maps. The fundamentals of the dynamics of this 4-parameter family of one-dimensional maps are presented. A complete classification of the nature and stability of its fixed points is provided. The main results relate to the Allee effect bifurcation: a new type of bifurcation introduced for this class of unimodal maps. A necessary and sufficient condition so that the Allee fixed point is a snap-back repeller is established. In addition, in the parameters space is defined an Allee’s effect region, which determines the existence of an essential extinction for the generalized logistic maps. Local and global bifurcations of generalized logistic maps are investigated.

Labour Regulation

The digital era has changed employment relationships dramatically, causing a considerable degree of legal uncertainty as to which rules apply in cyberspace. Technology is transforming business organisation in a way that makes employees – as subordinate workers – less necessary. New types of companies, based on the ‘on-demand economy’ or so-called ‘sharing economy’ and dedicated to connecting customers directly with individual service providers, are emerging. These companies conduct their entire core business through workers that they classify as self-employed. In this context, employment law is facing its greatest challenge, as it has to deal with a very different reality to the one existing when it was created. This article analyses the literature available about the classification of this new type of worker as an employee or as self-employed, concluding that there is a need for a new special labour regulation. It also describes and justifies the bases for this new special labour regulation.

Semantic Data Mining

The authors propose a new method for mining sets of patterns for classification, where patterns are represented as SPARQL queries over RDFS. The method contributes to so-called semantic data mining, a data mining approach where domain ontologies are used as background knowledge, and where the new challenge is to mine knowledge encoded in domain ontologies, rather than only purely empirical data. The authors have developed a tool that implements this approach. Using this the authors have conducted an experimental evaluation including comparison of our method to state-of-the-art approaches to classification of semantic data and an experimental study within emerging subfield of meta-learning called semantic meta-mining. The most important research contributions of the paper to the state-of-art are as follows. For pattern mining research or relational learning in general, the paper contributes a new algorithm for discovery of new type of patterns. For Semantic Web research, it theoretically and empirically illustrates how semantic, structured data can be used in traditional machine learning methods through a pattern-based approach for constructing semantic features.

The article considers the drawbacks of modern monetary-currency systems and their nonconformity to the requirements of current and future technological possibilities of the most world’s countries is concluded. It is substantiated that the principle of benchmarking of currency purchasing power unit in modern monetary-currency systems causes such nonconformity. The evolution character of changing one another benchmarking methods of purchasing power is discussed. The classification of money types and monetary system classes according to a joint classification attribute: benchmarking method of purchasing power, is offered. The hypothesis of the existence of the law describing the correlation between the benchmarking method of currency purchasing power and the economic-technological civilization development level is grounded. The conclusion is drawn that a new type of virtual money with a constant purchasing power has to emerge as the result of this law effect at the national level. At the international level, in future the same demand for correspondence will firstly bring about the making up of supranational units of account of regional and political alliances of countries and then the emergence of supranational world’s currency with a constant purchasing power.

The article, based on mathematical model of the space and particles revealed in "Theory of Space" (Sobolewski D. S., Theory of Space, 2016) (Sobolewski D. S., Theory of Space, 2017) and the description of the propagation of photons stated in publication entitled “Geometry of the Dark Matter and Preliminary Analysis of Alpha and Beta Photons’ Properties Based on Theory of Space” (Sobolewski, Sobolewski i Sobolewski, 2017), describes transverse waves propagating in space, including gravitational, fluctuating and matter waves. In particular, it focuses on waves of matter in which orientation of the spatial channels, connecting four-dimensional boundary hypersurfaces  and , had been stabilised. For this type of the wave of matter the minimum energy value for deformation of boundary hypersurfaces of the matter waves  has been appointed, which is smaller by several orders of magnitude than energy needed to change the orientation of vertical disturbances of space which connect four-dimensional boundary hypersurfaces and, The obtained results were used to introduce a new classification of rocket engines and to provide examples of their implementation. Furthermore, the article demonstrates first attempts to construct a rocket engine of the new type, including description of the principle of operation of the engine, which is subject of patent application entitled "HTS Photonic Rocket Engine" (Poland Patent nr P.421517, 2017), as well as presents an example of spacecraft shell implementation, which enables stabilization of orientation of its spatial channels. The Article thus reveals new perspectives for interplanetary travel through significant increase in spacecraft velocities, while simultaneously reducing the energy required to achieve them. In addition, the article describes interaction of photons  with the boundary hypersurface , while determining the change in photon frequency depending on its curvature .

The improper description and classification of two Polish cultivars of China aster ('Roma' and 'Srebrzysta Gwiazdka') were corrected. A new type of ray florets with tubular-ligulated (RJ type) and closed tubular (RC type) corollas was described. The type of heredity of the above mentioned types of florets and florets with ligulated corollas was determined. The work is based on our own material: radiomutant MG and its offspring as well as the F<sub>1 </sub; and F<sub>2 </sub; generations of hybrids obtained after crossing three cultivars: 'Goplana' x 'Roma' and 'Goplana' x 'Srebrzysta Gwiazdka' (i.e. J type x RC type). It was observed that the RJ type of corollas did not remain in the type. In the offspring of plants with such florets, always three types of segregants were present: plants with ray florets with ligulated, tubular - ligulated and tubular corollas. It was proved that it corresponds to the 1 :2: 1 ratio. It means that the formation of the RJ type corollas results from the presence of both alleles in the heterozygote. It was proposed to mark the gene conditioning the ligulated corolla form with the symbol L<sub>t</sub; (from Liguliformes) and the total corolla accretion with the symbol l<sub>1 </sub;. Thus the described phenotypes correspond to the following genotypes: L<sub>t</sub;L<sub>t</sub; - determines the appearance of ligulated corollas, L<sub>t</sub;l<sub>t</sub; - tubular - ligulated corollas and l<sub>t</sub;l<sub>t</sub; - closed tubular corollas.

Abstract Background: There is a high probability of gastroesophageal reflux after laparoscopic proximal gastrectomy for adenocarcinoma of the oesophagogastric junction (AEG). Various anti-reflux anastomotic methods are emerging in clinical practice; however, none of them have been widely accepted. We have innovated a new type of anti-reflux anastomotic method, named semi-embedded valve anastomosis. The aim of this study was to explore the feasibility and anti-reflux effect of the new anastomotic method.Methods: The clinical data of 28 patients with Siewert II AEG who were treated by semi-embedded valve anastomosis were collected. The key point of the operation is to reconstruct a simulated valve and form an anti-reflux barrier similar to the physiological mechanism. The gastroesophageal reflux disease questionnaire (GerdQ) and classification of gastroesophageal reflux under electron microscopy were used to evaluate gastroesophageal reflux after the operation.Results: The mean operative duration was 164.3±19.0 min, the median intraoperative haemorrhage volume was 65 ml, the average number of lymph nodes dissected was 23±2.6, the time for valve construction was 15.8±3.2 min, the time for anastomotic reconstruction was 35.4±4.8 min, the median time to first flatus was 3 d, and the median hospitalization duration was 12 d. There was one case of postoperative anastomotic stenosis. The GerdQ score [median (range)] was as follows: 2 (0-6), preoperation; 0 (0-8), 1 month postoperation; 2 (0-12), 3 months postoperation; and 3 (0-12), 6 months postoperation. The Wilcoxon signed-rank sum test was carried out at different times after the operation and the day before the operation, and the differences were not significant (P<0.05). There was one case of grade B gastroesophageal reflux according to the Los Angeles classification system among the gastrofibroscopic re-examination reports of 28 cases.Conclusion: Semi-embedded valve anastomosis is safe and feasible after proximal gastrectomy for Siewert II AEG and has good anti-reflux effects.
