Are Lebed's Magic Angles Truly Magic?
We report high-resolution angle-dependent measurements of the Periodic Orbit Resonance (POR) effect in (TMTSF):CI04. We observe additional harmonic resonances that were not observed in previous studies. By measuring over a broad range of frequency, field, and field orientation, we find that all of the POR evolve from the Lebed magic angles observed in dc (co = O) AMRO measurements. However, we ...
متن کاملOn Barycentric-Magic Graphs
Let $A$ be an abelian group. A graph $G=(V,E)$ is said to be $A$-barycentric-magic if there exists a labeling $l:E(G)longrightarrow Asetminuslbrace{0}rbrace$ such that the induced vertex set labeling $l^{+}:V(G)longrightarrow A$ defined by $l^{+}(v)=sum_{uvin E(G)}l(uv)$ is a constant map and also satisfies that $l^{+}(v)=deg(v)l(u_{v}v)$ for all $v in V$, and for some vertex $u_{v}$ adjacent t...
متن کاملCreating Semi-Magic, Magic and Extra Magic n× n Squares when n is Odd
We define a simple algorithm for creating large numbers of semi-magic n× n squares when n is odd. Special cases of the algorithm can also be used to easily create magic and extra magic (or panmagic) n× n squares when n is odd. The algorithm can also create extremely magic n × n squares when n ≥ 5 is prime. These extremely magic n × n squares have n! standard magic n-element subsets, and these n...
متن کاملEarth magic
FRANCIS HITCHING, Earth magic, London, Cassell, 1976, 8vo, pp. xiv, 196, illus., £4.50. For centuries the stone circles, barrows, dolmens and hill "forts" that are found in Northern Europe and Britain have attracted continual attention and bitter controversy. They mostly date from the fifth to second centuries B.C. and many of them have been shown to have acted as calendars and prognosticators ...
متن کاملA \varGamma -magic Rectangle Set and Group Distance Magic Labeling
A Γ -magic rectangle set MRSΓ (a, b; c) of order abc is a collection of c arrays (a× b) whose entries are elements of group Γ , each appearing once, with all row sums in every rectangle equal to a constant ω ∈ Γ and all column sums in every rectangle equal to a constant δ ∈ Γ . In the paper we show that if a and b are both even then MRSΓ (a, b; c) exists for any Abelian group Γ of order abc. Fu...
