A joint speech signal enhancement based on singular value decomposition filter after spectral subtraction (SSVD) is proposed in this paper. The residual noise after spectral subtraction, which results for audible musical noise, is reduced further by SVD filter. The matrix size in spectral domain can be reduced half, and larger step-length adopted by SVD filter in spectral domain leads to lower ...

34 Recent studies have associated increasing temporal expectations with synchronisation 35 of higher frequency oscillations and suppression of lower frequencies. In this experiment, we 36 explore a proposal that low-frequency oscillations provide a mechanism for regulating 37 temporal expectations. We used a speeded go/no-go task, and manipulated temporal 38 expectations by changing the probabi...

The notion of strongly Lie zero-product preserving maps on normed algebras as a generalization of Lie zero-product preserving maps are dened. We give a necessary and sufficient condition from which a linear map between normed algebras to be strongly Lie zero-product preserving. Also some hereditary properties of strongly Lie zero-product preserving maps are presented. Finally the second dual of...

the release of fe from soil solid phases into soil solution is a dynamic process that regulates the continuous supply of this element to growing plants. to ascertain the pattern of fe release, the kinetics of fe release from six soils by diethylenetriaminepentaacetic acid (dtpa) solution were investigated using soil samples taken from two different agroclimatic regions of iran. all soils were c...

the bulk of our knowledge on immunosuppression in malnutrition comes from the experiments done on cell-mediated immunity. however, malnutrition-induced modifications of humoral immunity have been less understood. the objective of this study was to determine the effects of acute protein-energy malnutrition on serum levels of immunoglobulins and their subclasses in murine models. male and female ...
