Motion of quantum vortex lines near realistic rough boundaries
No full textWe numerically solve the three--dimensional, time--dependent Gross--Pitaevskii equation to model a superfluid flowing over a realistic rough boundary. Our model for the boundary is based on the atom--force microscope image of a NbTi vibrating wire used to generate turbulence in actual experiments. We find that near the boundary a dense region of quantum vortices is created, which forms a kind of `superfluid boundary layer'
Wave excitations in adjacent vortex filaments
No full textThe interactions of the nearest neighbour vortices are argued to play a significant role in the crossover range of scales that lies between the Kolmogorov-Richardson cascade and the Kelvin wave driven cascade in superfluid turbulence. In this work, we study how a wave excitation (a Kelvin wave or a soliton) on a vortex affects a nearby straight vortex. Our numerical simulations reveal that coherent excitations can hop from one vortex filament to another whilst retaining their coherent properties
Spectral properties of Andreev reflection from quantum turbulence in 3He-B: What do they tell about turbulent fluctuations?
No full textOne of the experimental techniques developed to measure quantum turbulence at low temperatures in 3He-B utilizes the Andreev reflection of thermal quasiparticle excitations from quantized vortices and vortex structures. We present the results of theoretical, numerical, and experimental study of Andreev scattering from quantum turbulence in 3He-B. We analyze the spectral properties of the Andreev reflection and compare these with the spectral properties of superfluid turbulence, and discuss the physical mechanisms responsible for the scaling of spectral densities. Finally, we discuss the relation between our findings and related observables in ordinary turbulence
Restoring Indigneous Law and Justice Traditions
No full textRestoring indigenous people's law and their ability to practice their justice traditions is a fundamental aspect of non-discrimination, decolonization, self-governance, self-determination, and social justice. The critical application and interpretation of indigenous people's law has revolutionary potentiality to transform, confront, and heal multiple forms of oppression such as environmental destruction, patriarchy, and the prison/criminal justice system. The sovereign jurisgenerative (law making) power of indigenous peoples is a site of profound hope for the revitalization of indigenous law and justice traditions restores legal principles and values of sacredness, harmony, balance, and interconnectivity within human relationships and with the natural world. Revitalizing indigenous law is a way to re-construct the self and society while also finding and re-connecting to new/old ways of being human. This thesis focuses on both Navajo and Māori practices and visions of law and justice; the challenges and, successes they have faced and the hopes they have of living by their law. Indigenous peoples, their ways of being, their wisdom, laws, and philosophies, must be respected, protected, and preserved not only because they contribute to humanity's richness and cultural diversity but also because they are living examples of a more just, dignified, and ecologically sustainable society, which can serve all humanity

A Fuzzy-based Scoring Rule for Author Ranking: an alternative to h-index
No full textThe measurement of the quality of research has reached nowadays an increasing interest not only for scientific reasons but also for the critical problem of researchers' ranking, due to the lack of grant assignments. The most commonly used approach is based on the so-called h-index, even if the current literature debated a lot about its pros and cons. This paper, after a brief review of the h-index and of alternative models, focuses on the characterization and the implementation of a modified scoring rule approach by means of a fuzzy inference system a là Sugeno

Scale c.a. 1:60,000,000.Charles Francois Delamarche (1740-1817) was a geographer, publisher and globe maker. He was Didier Robert de Vaugondy's successor after his death and reissued a number of his atlases. Delmarche's work includes "USA" (1785), "Globes' (1785-1800), "Institutions géographiques des globes" (1791), "Tableaux géographiques" (1794), "Atlas d'Etude" (1797) and "World and Continents" (1805).
James Cook (1728-1779) was an English navigator and hydrographer who conducted extensive naval expeditions involving the survey of Newfoundland and exploration in the south Pacific Ocean and the northwest coast of North America. Throughout his three major voyages in the 1760s and 1770s, Cook encountered New Zealand, Australia, the Hawaiian Islands, and the Bering Strait. After great success on his second voyage circumnavigating the globe, he was elected to the Royal Society and given the rank of post-Captain. During his last voyage through the south Pacific Ocean and the northwest coast of North America from 1776-1779, he died in a skirmish with native inhabitants of Hawaii on February 14, 1779. Following his death, Charles Clerke took over charge of the expedition (Howgego, 254-58).
John Meares (1756-1809) was an English se trader and captain. After founding the Bengal Fur Company, he sailed from Calcutta, India in March 1786 to Nootka on Vancouver Island. He stayed in Alaska during that winter and then returned to China in 1787. He later came back to the North American northwest with a large crew under him two ships: Iphigenia Nubiana and Felice Adventurer. The Iphigenia went to the Aleutians and Queen Charlotte Islands. Meares later returned to China, 1788-9. He supported British claims on the area and his writings led to a British negotiation with the Spanish who had also laid claim to Nootka Sound (Howgego, 698).
