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 ...

On 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...

Neutrino oscillations : what is magic about the “ magic ” baseline ?

Physics interpretation of the " magic " baseline, L magic , that can play important role in future oscillation experiments is given. The " magic " baseline coincides with the refraction length, l 0. The latter, in turn, approximately equals the oscillation length in matter at high energies. Therefore at the baseline L = l 0 the oscillation phase is 2π, and consequently, the " solar " amplitude ...

The Not-so-Magic Magic Barrier of Recommender Systems

Recommender Systems need to deal with different types of users who represent their preferences in various ways. This difference in user behaviour has a deep impact on the accuracy of the recommendations received by the users, depending, mostly, on the quantity and the quality of the information the system knows about the user. Specifically, the inconsistencies of the user impose a lower bound o...
