President Obama urged educators abandon severe disciplinary policies criminalize for offenses could be handled without law enforcement (Du, 2015). A review literature ...

The protected helical surface states in thin films of topological insulators (TIs) are subject to intersurface hybridization. This leads gap opening and spin texture changes as witnessed photoemission quasiparticle interference investigations. Theoretical studies show that universally, the hybridization energy exhibits exponential decay well sign oscillations a function film thickness, dependin...
