Opis:: Motion of kink solitons in the φ$\text{}^{4}$ model in the presence of external spatially inhomogeneous forces is studied. Depending on the system parameters various routes to chaos, i.e. Feigenbaum's scenario, type-I intermittency, and chaos-chaos intermittency are observed. Synchronization of chaotic solitons is investigated.

Opis:: An experimental setup has been designed that makes possible a real-time noise reduction and an increase of automatic word recognition rate. The applied algorithm uses a dynamical filtering method for investigated time-series and has been implemented in Spartan 3 FPGA evaluation board RC10 made by Celoxica. We show that our approach increases the number of correctly recognized words in the commercial speech recognition program ViaVoice 10.

Opis:: In this paper, we investigate the statistical features of the weighted international-trade network. By finding the maximum weight spanning trees for this network we make the extraction of the truly relevant connections forming the network's backbone. We discuss the role of large-sized countries (strongest economies) in the tree. Finally, we compare the topological properties of this backbone to the maximum weight spanning trees obtained from the gravity model of trade. We show that the model correctly reproduces the backbone of the real-world economy.

Opis:: Alcohol related harm is a global problem for public health where frequent consumption of large amounts of alcohol constitutes a serious health risk, particularly to vulnerable groups such as adolescents, pregnant women and newborns. The epidemiological study on health-lifestyle behaviour, especially alcohol consumption, was performed on a randomised group of post-partum women’s health behaviour during pregnancy, covering drinking habits, was undertaken in 2010, 2011 and 2012, (n=8,237) according to the PRAMS model including effects on the foetus and newborn; women being selected from obstetric and gynaecological wards. In this Polish study, only 14% of women did not consume alcohol before becoming pregnant while 15% of women drank alcohol throughout the entire period of pregnancy. In addition, awareness of the harmful effects of alcohol consumed, especially of small amounts, before and during pregnancy is low among Polish women. It is also alarming that more than 55% of physicians who provide care for pregnant women do not discuss with them the harmful effect of alcohol on the organism of the mother and foetus, whereas over 2% of doctors even recommend the consumption of alcohol in pregnancy. With reference to the Barker’s Foetal Origin of Diseases Hypothesis, the authors suggest such alcohol drinking behaviour of women during their reproductive ages and while pregnant may exert negative health effects on offspring, mainly in the form of susceptibility to contracting chronic diseases. Such findings pose a risk to future generations in Poland and require remedial/educational action targeted on health care professionals and public like.
