Orbital Fluctuation-Induced Triplet Superconductivity : Mechanism of Superconductivity in Sr2RuO4{\rm Sr}_{2}{\rm RuO}_{4}

The mechanism of superconductivity in ${\rm Sr}_{2}{\rm RuO}_{4}$ is studied using a degenerate Hubbard model within the weak coupling theory. When the system approaches the orbital instability which is realized due to increasing the on-site Coulomb interaction between the electrons in the different orbitals, it is shown that the triplet superconductivity appears. This superconducting mechanism is only available in orbitally degenerate systems with multiple Fermi surfaces.Comment: 5 pages, 4 figure

Academic entrepreneurship : a source of competitive advantage

This�report is the result of a cooperation between�EIM,�Erasmus University�and Indiana University. The study has largely been executed by students of�the assocation�'Le Manageur'�under supervision of�the above institutions. The study evaluates university�spin-offs�in the transfer of� technology from universities into society and provides a comparative case study of spin-off� stimulation. The study concludes that governments that would like to tackle�problems in�knowledge transfer between firms and public institutions should�encourage knowledge institutions to adopt a more proactive stance towards commercialization and cooperation. Stimulating an entrepreneurial spirit and knowledge spin-offs in public research and educational institutions�can help overcome many of the problems in knowledge transfer. This research shows that spin-offs�are�a good supplement to existing transfer mechanisms such as�licensing and contract research. University spin-offs�are a good way to transfer�radical and incremental technologies�to society.�This form of technology transfer does require a strong supporting infrastructure and sufficient entrepreneurial human capital.

Results from MAGIC Observations of Extragalactic Relativistic Sources

The Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) experiment is an array of two 17-meter telescopes located in the Canary Island of La Palma that observes the very-high energy (VHE) gamma-ray sky in stereoscopic mode since 2009. MAGIC is distinguished by its low-energy threshold of approximately 50 GeV, which grants the system a unique potential in the study of distant extragalactic sources whose gamma-ray emission is significantly attenuated due to absorption by the extragalactic background light (EBL). The observation of non-thermal gamma rays in the GeV-TeV range from extragalactic sources is a characteristic signature of their relativistic nature and therefore fundamentally important for our understanding of the physics of these objects. Since the beginning of its stereo operation, MAGIC has observed a large number of active galactic nuclei (AGN) of different classes, including several blazars and distant quasars. In this paper we will review some of the most important results of these observations.Comment: 7 pages, 2 figures, Observational Review talk given at HEPRO-III Conference, Barcelona, June 201

RRS Discovery Cruise 368, 15 Jul - 04 Aug 2011. Hydrographic measurements on WOCE line A16N

RRS Discovery Cruise 368 was a repeat occupation of part of the Atlantic hydrographic section designated by the World Ocean Circulation Experiment (WOCE) as A16N. A total of 29 CTDO (conductivity-temperature-depth-oxygen) stations were occupied. This included one test station, 27 stations between 49N and 23N on the WOCE A16N ‘20W’ line, and one final station near the ESTOC site close to Tenerife. Continuous profile measurements were CTDO and Lowered Acoustic Doppler Current Profiler (LADCP). Discrete bottle measurements from a 24-place rosette included salinity and dissolved oxygen analysed on board, and dissolved inorganic nutrients, Dissolved Inorganic Carbon and Total Alkalinity for analysis ashore. Underway measurements included Vessel-Mounted ADCP, surface ocean measurements and surface meteorology. The cruise was a UK contribution to the GO-SHIP sustained hydrography program. It was a partial repeat of the line designated in WOCE as A16N, which was previously occupied as a comprehensive cruise in 2003. In addition, a microbial program was carried out as an opportunistic activity by scientists who would remain on board for the following cruise.This report describes the methods used to acquire and process the data on board the ship during RRS Discovery Cruise 368.<br/
