Spectrally constrained sequences (SCSs) play an important role in modern communication and radar systems operating over non-contiguous spectrum. Despite numerous research attempts the past years, very few works are known on constructions of optimal SCSs with low cross-correlations. In this paper, we address such a major problem by introducing unifying framework to construct unimodular SCS famil...

Even correlation and odd of sequences are two kinds measures for their similarities. Both have important applications in communication radar. Compared with vast knowledge on good even correlation, relatively little is known preferable correlation. In this paper, a generic construction low proposed via interleaving technique. Notably, it can generate new sets binary optimal asymptotically meetin...

Nonlinear Boolean functions play an important role in the design of block ciphers, stream ciphers and one-way hash functions. Over the years researchers have identi5ed a number of indicators that forecast nonlinear properties of these functions. Studying the relationships among these indicators has been an area that has received extensive research. The focus of this paper is on the interplay of...

We study in QCD the physics of deeply-virtual Compton scattering (DVCS)—the virtual Compton process in the large s and small t kinematic region. We show that DVCS can probe a new type of off-forward parton distributions. We derive an Altarelli-Parisi type of evolution equations for these distributions. We also derive their sum rules in terms of nucleon form-factors of the twist-two quark and gl...

Objectives. The aim of this study is to introduce a new way and assign its reliability and validity in measuring the angle of hallux valgus. Methods. In this method, we have proceeded to introduce a simple way for measuring the angle of hallux valgus by using ruler and mathematical formulas. For doing this study, we selected 25students and measured their angle of hallux valgus with new way ...
