Using the double covering approach introduced by B. Helffer, M. and T. HoffmannOstenhof and M. Owen and further developed for questions of isospectrality by the authors in collaboration with T. Hoffmann-Ostenhof, we analyze the variation of the eigenvalues of the one pole Aharonov-Bohm Hamiltonian on the square and the nodal picture of the associated eigenfunctions as a function of the pole. Th...
OBJECTIVE To compare the location and multiplicity of mandibular fractures in Kuwait, Canada and Finland during the 1990s.

Climate variation and human activities are commonly recognized as two major factors affecting basin hydrology. However, quantifying their individual effect on runoff is challenging. In this study, long-term (1960–2009) river discharge and weather data in the Songhua River Basin (SRB, 556,800 km2), Northeast China, were gathered to separate the impacts of climate variation and human activities o...
