The timebase distortion present in an equivalent-time sampling oscilloscope introduces errors in the estimation of the values of the spectral components of a microwave signal when a classical discrete Fourier transform is used. In this article a method is developed to avoid these errors. The method is tested both in practice and with simulations. Two parts can be distinguished. At first, the ti...

Electron spin resonance (ESR) and absorption spectral studies are described which demonstrate two types of cyanide complex of Co(I1) human carbonic anhydrase B. High spin (S = 3/2) Co(I1) is present at the active site of the cobalt enzyme in the presence of both 1 and 2 eq of CN-’ at room temperature. At liquid nitrogen temperature the 1: 1 complex remains high spin, while the enzyme in the pre...

In the context of the field theory we show that for particles with opposite non-commutativity, in QED, there is no correction for the two-body bound state at the tree level. Consequently, the Helium atom is considered in the non-commutative space. It is shown that the effects of spatial non-commutativity appear at the tree level and they are of the order α. ∗ email: [email protected] † email...

We study the effects of a uniform magnetic field on the one-dimensional spinorbital model in terms of effective field theories. Two regions are examined: one around the SU(4) point (J=K/4) and the other with K ≪ J [see Eq. (1)]. We found that when J ≤ K/4, the spin and orbital correlation functions exhibit power-law decay with non-universal exponents. In the region with J > K/4, the excitation ...

‎Suppose $n$ is a fixed positive integer‎. ‎We introduce the relative n-th non-commuting graph $Gamma^{n} _{H,G}$‎, ‎associated to the non-abelian subgroup $H$ of group $G$‎. ‎The vertex set is $Gsetminus C^n_{H,G}$ in which $C^n_{H,G} = {xin G‎ : ‎[x,y^{n}]=1 mbox{~and~} [x^{n},y]=1mbox{~for~all~} yin H}$‎. ‎Moreover‎, ‎${x,y}$ is an edge if $x$ or $y$ belong to $H$ and $xy^{n}eq y^{n}x$ or $x...

Exact solutions of the Nizhnik-Novikov-Veselov equation by Li [New kink-shaped solutions and periodic wave solutions for the (2+1)-dimensional Sine-Gordon equation, Appl. Math. Comput. 215 (2009). 3777-3781 ] are analyzed. We have observed that fourteen solutions by Li from thirty do not satisfy the equation. The other sixteen exact solutions by Li can be found from the general solutions of the...
