Time-shift estimation between arrivals in two seismic traces before and after a velocity perturbation is a crucial step in many seismic methods. The accuracy of the estimated velocity perturbation location and amplitude depend on this time shift. Windowed cross-correlation and trace stretching are two techniques commonly used to estimate local time shifts in seismic signals. In the work presen…

The feeding habits of Mullus barbatus larvae and the horizontal and vertical distribution of larvae and their dominant prey were studied in the NW Mediterranean during the summer oligotrophic period. The water column showed marked stratification with a deep chlorophyll maximum beneath the thermocline. Horizontal and vertical distribution of larvae showed good correspondence with that of cladoc…

We extend the theory of the universal η-invariant to the case of bordism groups of manifolds with boundaries. This allows the construction of secondary descendants of the universal η-invariant. We obtain an interpretation of Laures’ f -invariant as an example of this general construction. As an aside, we improve a recent result by Han–Zhang about the modularity of a certain forma…

The collection of Baron Ferdinand de Rothschild was assembled between 1874 and 1898. The display of objects within Rothschild homes of the Gilded Age shows that they formed part of the living space of the family rather than being isolated in showcases or other settings as we know them today in public institutions and museums: the items in question were integral to the lives of the collectors a…

This paper explores the origins and development of the Swann Collection of Caricature and Cartoon, begun by Erwin D. Swann in 1966, and currently held by the Library of Congress in Washington, dc. One of the world’s few collections dedicated to the preservation of original comic art by caricaturists and cartoonists from the eighteenth to the twentieth century, Swann’s collection also transc…

Evaluations of the Comprehensive Economic and Trade Agreement (CETA) among Canada and the European Union (EU) and of the ongoing EU�US negotiations on a Transatlantic Trade and Investment Partnership (TTIP) depend on their legal, economic, and political methodologies for multilevel governance of public goods (PGs) like a transatlantic market. In contrast to the American and European pos…

Scotland is a relatively aseismic region for the use of local earthquake tomography, but 40yr of earthquakes recorded by a good and growing network make it possible. A careful selection is made from the earthquakes located by the British Geological Survey (BGS) over the last four decades to provide a data set maximising arrival time accuracy and ray path coverage of Scotland. A large number of …

Current earthquake early warning (EEW) systems lack the ability to appropriately handle multiple concurrent earthquakes, which led to many false alarms during the 2011 Tohoku earthquake sequence in Japan. This paper uses a Bayesian probabilistic approach to handle multiple concurrent events for EEW. We implement the theory using a two-step algorithm. First, an efficient approximate Bayesi…

The Fisher distribution is central to palaeo magnetism but presents several problems when used to characterize geomagnetic field directions as observed in sequences of volcanic rocks. First, it introduces a shallowing effect when used to define the mean of any group of directional unit vectors. This is problematic because it can suggest the presence of persistent non-axial dipole co…
