Based on dynamic features of human speech, the local projection (LP) method has been adapted to the enhancement of speech corrupted by white noise. As an extension of the LP method, a strategy with two rounds of projection is introduced to enhance the speech contaminated with colored noise. Colored noise mainly resides in a low dimensional subspace, and is assumed to be stationary in this commu...

to evaluate morphological markers linked with drought stress resistance for screening almond genotypes in the breeding programs the effect of drought stress was studied on six nominated almond genotypes seedlings. the six pre-selected water stress mimposed almond genotypes included: homozygote sweet (butte from university of california), heterozygote sweet (shahrood12, shahrood18, shahrood21 an...

This research was carried out to compare the productivity performance of three lines local quail. The results showed a significant superiority in daily gain weight (3.76 g/day/quail) and marketing (167.2 g/quail) for brown quail over other colors. Also, differences were found dressing ratio between males (67.8%) females (65.76%). As egg production quail, it desert colors number eggs produced, a...

Catharanthus roseus or vinca produces over 130 TIAs with pharmaceutical value. Two of them, namely vinblastine (VB) and vincristine (VC), are species-specific and extensively used in anticancer chemotherapeutics. To detect C. roseus genotypes abundant in desired TIAs, contrasting genotypes should be analyzed via marker-assisted selection (MAS) to avoid analytical quantitation. A trustable morph...

A generalized subspace approach is proposed for enhancement of speech corrupted by colored noise. A nonunitary transform, based on the simultaneous diagonalization of the clean speech and noise covariance matrices, is used to project the noisy signal onto a signal-plus-noise subspace and a noise subspace. The clean signal is estimated by nulling the signal components in the noise subspace and r...

Twenty-three coffee (Coffea arabica) genotypes were evaluated for relative resistance against white stem borer (Xylotrechus quadripes) and leaf rust (Hemileia vastatrix) at Horticulture Research Station, Malepatan, Pokhara during three consecutive years from 2016 to 2019. The monthly observation on the emergence of this showed that "Yellow caturra" “Tekisic” highly infested with as compared oth...

As in many clades of flowering plants, the Quamoclit clade of morning glories (Ipomoea subgenus Quamoclit) exhibits unequal proportions of different flower colors, with pigmented species outnumbering unpigmented species by nearly a factor of 7. We examined three possible macroevolutionary explanations for this pattern: (1) asymmetric transition rates between pigmented and unpigmented flowers; (...

A coloring of the edges of Kn is constructed such that every copy of K4 has at least three colors on its edges. As n → ∞, the number of colors used is eO( √ log n ). This improves upon the previous probabilistic bound of O( √ n ) due to Erdős and Gyárfás.
