Tree-structured complementary filter banks using all-pass sections [PDF]

open access: yes, 1987
Tree-structured complementary filter banks are developed with transfer functions that are simultaneously all-pass complementary and power complementary.

The block-ZXZ synthesis of an arbitrary quantum circuit [PDF]

open access: yes, 2016
Given an arbitrary $2^w \times 2^w$ unitary matrix $U$, a powerful matrix decomposition can be applied, leading to four different syntheses of a $w$-qubit quantum circuit performing the unitary transformation.

Symmetric spaces of higher rank do not admit differentiable compactifications [PDF]

open access: yes, 2009
Any nonpositively curved symmetric space admits a topological compactification, namely the Hadamard compactification. For rank one spaces, this topological compactification can be endowed with a differentiable structure such that the action of the ...

Hadamard partitioned difference families and their descendants [PDF]

open access: yes, 2018
If $D$ is a $(4u^2,2u^2-u,u^2-u)$ Hadamard difference set (HDS) in $G$, then $\{G,G\setminus D\}$ is clearly a $(4u^2,[2u^2-u,2u^2+u],2u^2)$ partitioned difference family (PDF). Any $(v,K,\lambda)$-PDF will be said of Hadamard-type if $v=2\lambda$ as the

On the novel Hermite-Hadamard inequalities for composite inverse functions

open access: yesFilomat, 2023
The goal of this research is to discover some identities in the general form of the sum of left and right-sided weighted fractional integrals of a function concerning to another function. Using composite convex functions, several fractional Hermite-Hadamard inequalities are derived.

Inference on Counterfactual Distributions [PDF]

open access: yes, 2012
Counterfactual distributions are important ingredients for policy analysis and decomposition analysis in empirical economics. In this article we develop modeling and inference tools for counterfactual distributions based on regression methods.

Manin products, Koszul duality, Loday algebras and Deligne conjecture [PDF]

open access: yes, 2006
In this article we give a conceptual definition of Manin products in any category endowed with two coherent monoidal products. This construction can be applied to associative algebras, non-symmetric operads, operads, colored operads, and properads ...

Composite Minimization Problems in Hadamard Spaces

open access: yesJournal of Applied Mathematics and Physics, 2020
In this paper, we prove some Δ-convergence and strong convergence results for the sequence generated by a new algorithm to a minimizer of two convex functions and a common fixed point for quasi-pseudo-contractive mappings in Hadamard spaces. Our theorems improve and generalize some recent results in the literature.

A Characterization of Generalized Boolean Functions Employed in CDMA Communications [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
In design of secure cryptosystems and CDMA communications, the negabent functions play a significant role. The generalized Boolean functions have been extensively studied by Schmidt and established several important results in this setup.

Some Cryptographic Properties of Functions Based on their 2q-Nega-Hadamard Transform [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
Negabent functions play a vital role in the field of cryptography and coding theory for designing secure cryptosystems. In this article, we investigate the various properties of 2q-nega-Hadamard transform (2q-NHT) of the functions from Z_q^n to Z_2q with
