AMMI analysis of 21 malt barley genotypes evaluated at nine locations north western plains zone revealed highly significant variation due to environments (61.8%), G x E interactions (19.5%) and (8.2%). Further, interaction effects were partitioned into seven principal components. stability Value measures (ASV1 ASV) had considered first two  components based on 54.1% total variations recomm...

Motivated by the fact that twice Fourier transform plays role of parity operator. We systematically study integral transforms in case $\mathcal{PT}$-symmetric Hamiltonian. First, we obtain a closed analytical formula for exponential general Using Segal-Bargmann transform, investigate effect on eigenfunctions original As an immediate application, comment holomorphic representation non-Hermitian ...

Causal broadcast is a fundamental communication abstraction for many distributed applications. Several implementations of this have been proposed over the last decades traditional networks, that is, networks assume existence continuous bi-directional end-to-end path between any pair nodes. Opportunistic constitute kind in which assumption cannot be made, though, so implementation causal such mu...

Very recently, extended fractional cumulative residual entropy (EFCRE) has been proposed by Foroghi et al., (2022). In this paper, we introduce past (EFCPE), which is a dual of the EFCRE. The newly measure depends on logarithm order and distribution function (CDF). Various properties EFCPE have explored. This to bivariate setup. Furthermore, conditional studied some its are provided. for inacti...

In this paper we define a new class of partially filled arrays, called λ-fold relative Heffter that are generalization the arrays introduced by Archdeacon in 2015. After showing connection concept with several other ones, such as signed magic graph decompositions and difference families, determine some necessary conditions present existence results for infinite classes these arrays. last part a...
