For c > 1, c / ∈ Z and χ a primitive character (mod q), we estimate the sum  x

Earthquake focal mechanisms of the Shanxi rift system, North China, are investigated for the time period 1965–April 2014. A total of 143 focal mechanisms of ML ≥ 3.0 earthquakes were compiled. Among them, 105 solutions are newly determined in this study by combining the Pwave first motions and full waveform inversion, and 38 solutions are from available published data. Stress tensor inv…

We examine P-wave velocity structure at the base of the mantle beneath the western Pacific, near the western edge of the Pacific Large-Low Shear Velocity Province (LLSVP), using high-quality seismograms provided by a large-scale mobile broad-band seismic observation in north eastern China (the NECESSArray project). Forward modelling using the reflectivity method is conducted t…

Frequency domain decomposition (FDD) is a well-established spectral technique used in civil engineering to analyse and monitor the modal response of buildings and structures. The method is based on singular value decomposition of the cross-power spectral density matrix from simultaneous array recordings of ambient vibrations. This method is advantageous to retrieve not only the resonance freque…

Conservation physiology aims to apply an understanding of physiological mechanisms to management of imperiled species, populations, or ecosystems. One challenge for physiologists hoping to apply their expertise to conservation is connecting the mechanisms we study, often in the laboratory, with the vital rates of populations in the wild. There is growing appreciation that infectious pathogens c…

The strength of a polyphase aggregate comprising power-law materials is a function of the constitutive laws of the phases present, the arrangement of those phases and environmental conditions such as temperature. Primarily for geological applications, we consider the degree to which the arrangement of the phases has a significant influence on bulk strength. Calculations based on cur…

This paper examines the determinants of net interest margins (NIMs) in four regional blocks in Sub-Saharan Africa (SSA). Using bank-level data,we find that countries with a high level of operating costs, a lowlevel of non-interest income, a high ratio of equity to total assets and high treasury-bill interest rates have higher NIMs. Moreover, high operating costs are associated with low measur…
