Perceptual parsing of a complex acoustic scene requires the following ingredients: (a) a representation that is “separable” in the sense that it allows patterns to be split into parts that belong to diverse sources, (b) rules and cues to guide the partition, and (c) processes that can make sense of the partitioned information in the event that the partition was imperfect and the partitioned inf...

Mobile terminals are often used indoor with the base station outdoors. At the mobile terminal the major part of the signal energy comes through openings in the building such as windows. Typically, only one of the sides in a room has windows, and seldom does a room have windows on all sides. Hence, the dominating signal can be expected to arrive at the mobile terminal from a narrow range of angl...

INTRODUCTION: H MRS is evolving into an invaluable tool for tumor classification in human patients based on pattern recognition analysis [1] but there is still room for improvement. Here we propose a new approach in this direction: to challenge tumor metabolism in vivo by a defined perturbation and monitor MR spectral pattern changes. PURPOSE: To monitor tumor H MRS pattern changes in mice bear...

Abstract The observed spectral shapes variation and tentative bimodal burst energy distribution (E-distribution) of fast radio (FRB) 20121102A with the FAST telescope are great puzzles. Adopting published multifrequency data Arecibo telescopes at L band Green Bank Telescope (GBT) C band, we investigate these puzzles through Monte Carlo simulations. intrinsic function (E-function) is modeled as ...
