Instanton size distribution in O(3)

We present calculations of the size distribution of instantons in the 2d O(3) non-linear sigma-model, and briefly discuss the effects cooling has upon the configurations and the topological objects.

Natural history of G ynaikothrips uzeli (Thysanoptera, Phlaeothripidae) in galls of Ficus benjamina (Rosales, Moraceae)

ABSTRACT Galls induced by thrips are simple structures when compared to those of other groups of arthropods, and little is known regarding many of their aspects. This study aimed to investigate aspects of the natural history of Gynaikothrips uzeli Zimmermann, 1900 in galls of Ficus benjamina L., 1753 using seasonal sampling (summer and winter). Twenty trees were sampled and divided into quadrants. From each of them, five galls were collected, forming a total of 400 galls per collection. Thrips showed greater abundance at higher temperatures (25.7°C) and no precipitation. Sex ratio was biased towards females (0.022 males per female), pointing to an inbred mating structure. Arthropod fauna associated with galls was more abundant (N=798) in winter, and it included representatives of the orders Hemiptera, Hymenoptera, Araneae, Coleoptera, Neuroptera, Psocoptera, Thysanoptera, Diptera and Blattodea

Using human induced pluripotent stem cells to treat retinal disease

AbstractThe eye is an ideal target for exploiting the potential of human induced pluripotent stem cell (hiPSC) technology in order to understand disease pathways and explore novel therapeutic strategies for inherited retinal disease. The aim of this article is to map the pathway from state-of-the art laboratory-based discoveries to realising the translational potential of this emerging technique. We describe the relevance and routes to establishing hiPSCs in selected models of human retinal disease. Additionally, we define pathways for applying hiPSC technology in treating currently incurable, progressive and blinding retinal disease

‘Repeal the 8th’ in a Transnational Context: The Potential of SRHRs for Advancing Abortion Access in El Salvador

This article undertakes a discursive feminist reading of citizenship and human rights to understand, through the cases of Ireland and El Salvador, domestic abortion rights movements as part of a transnational women’s rights movement. While abortion has been partially decriminalised in Ireland, approximately 42 per cent of the world’s women1 of reproductive age still live in a country where abortion is prohibited entirely or only permitted to save a woman’s life or health (Singh et al., 2018, p. 4). In El Salvador, abortion is illegal and those suspected of having the procedure are prosecuted. As in Ireland, since 2012/2013 numerous controversies have brought the issue to wider public attention and have further galvanised the feminist movement to campaign for reform. Feminist abortion rights campaigns in both countries have connected important sites of activism and contestation: civil society, national parliaments, regional human rights systems and the United Nations
