It has been noticed that all the known binary sequences having the asymptotic merit factor ≥ 6 are the modifications to the real primitive characters. In this paper, we give a new modification of the character sequences at length N = p1p2 . . . pr, where pi’s are distinct odd primes and r is finite. Based on these new modifications, for N = p1p2 . . . pr with pi’s distinct odd primes, we can co...

The absolute value of the Möbius function of a bounded poset P with n + 2 elements satisfies |μ(P )| ≤ max r≥0 max p1+...+pr=n pi≥1 r ∏

This article takes its name and inspiration from Mad Professor’s album A Caribbean Taste of Technology in response to the theme of this Technosphere issue. This makes a good place to start a discussion of creolization and technology – the dub reggae tracks of this album produced British producer Mad Professor and released in 1985, https://www.youtube.com/watch?v=ewDTHfJqLwI So what I present he...

The effects of replacing Pr by Lu on the magnetic behaviour and structures of Pr(1-x)Lu(x)Mn(2)Ge(2) (x = 0.2,x = 0.4) have been investigated using x-ray diffraction, Mössbauer spectroscopy, magnetization and neutron diffraction measurements. The substitution of Lu for Pr leads to a decrease in the lattice constants a, c and the unit cell volume V at room temperature with this contraction of th...

Addition of three equivalents of phosphinoamine, (ArNHP(i)Pr(2)) [Ar = 3,5-dimethylphenyl] to M(CH(2)SiMe(3))(3)(THF)(2) [M = Sc, Y] precursors gives complexes of the form (ArNP(i)Pr(2))(3)M(THF) [M = Sc, Y]. In the case of scandium, addition of Sc(CH(2)SiMe(3))(3)(THF)(2) to (ArNP(i)Pr(2))(3)Sc(THF) affords (ArNP(i)Pr(2))(2)Sc(CH(2)SiMe(3))(THF), which has been isolated and structurally charac...
