It is very important for a hands-free speech interface to capture distant talking speech with high quality. A microphone array is an ideal candidate for this purpose. However, this approach requires localizing the target talker. Conventional talker localization methods in multiple sound source environments not only have difficulty localizing the multiple sound sources accurately, but also have ...

Modern cosmological analyses of galaxy-galaxy lensing face a theoretical systematic effect arising from the non-locality observed signal. Because predicted tangential shear signal at given separation depends on physical modeling all scales internal to that separation, uncertainties in non-linear small are propagated outwards larger scales. Even absence other limiting factors, this alone can nec...
