Discovery of a Spin-Down State Change in the LMC Pulsar B0540-69
F. E. Marshall, L. Guillemot, A. K. Harding +2
We report the discovery of a large, sudden, and persistent increase in the spin-down rate of B0540-69, a young pulsar in the Large Magellanic Cloud, using observations from the Swi…
A community role approach to assess social capitalists visibility in the Twitter network
Nicolas Dugué, Vincent Labatut, Anthony Perez
In the context of Twitter, social capitalists are specific users trying to increase their number of followers and interactions by any means. These users are not healthy for the ser…
On SAT Models Enumeration in Itemset Mining
Said Jabbour, Lakhdar Sais, Yakoub Salhi
Frequent itemset mining is an essential part of data analysis and data mining. Recent works propose interesting SAT-based encodings for the problem of discovering frequent itemsets…
Identification of photospheric activity features from SOHO/MDI data using the ASAP tool
Omar Ashamari, Rami Qahwaji, Stan Ipson +3
The variation of solar irradiance is one of the natural forcing mechanisms of the terrestrial climate. Hence, the time-dependent solar irradiance is an important input parameter fo…
Wave propagation on Euclidean surfaces with conical singularities. I: Geometric diffraction
G. Austin Ford, Andrew Hassell, Luc Hillairet
We investigate the singularities of the trace of the half-wave group, , on Euclidean surfaces with conical singularities . We compute the leadi…
The peculiar radio galaxy 4C 35.06: a case for recurrent AGN activity?
A. Shulevski, R. Morganti, P. D. Barthel +85
Using observations obtained with the LOw Fequency ARray (LOFAR), the Westerbork Synthesis Radio Telescope (WSRT) and archival Very Large Array (VLA) data, we have traced the radio…
