The equations of motion (EOM) for Jeans the position and gauge invariant crystal momentum are considered for multiband wave packets of Bloch electrons.For a localized packet in a subset of bands well-separated from the rest of the band structure of the crystal, one can construct an effective electromagnetic Hamiltonian with respect to the center of

ABSTRACTObjectives To evaluate the effect and mechanism of action of the flavonoid phloretin on the growth and sucrose-dependent biofilm formation of Streptococcus mutans.Methods Minimum inhibitory concentration, viability, and biofilm susceptibility assays were conducted to assess antimicrobial and antibiofilm effect of phloretin.Biofilm compositi
Megatrends affect Swivel Chair all individuals and organizations in our society.Mobility and flexibility are examples of megatrends that influence our everyday lives and also intensely alter the ways we work.The deployment of virtual teams meets the new chances emerging with these trends.Employees aspire to work virtually due to benefits, such as f
In order to reveal the vibration characteristics of fault rotor systems caused by the bearing misalignment, the expression of the rotor deflection displacement under the bearing misalignment was derived through the coordinate transformation relation.On this basis, Glass Mister the dynamic model of the double disk rotor system with the coupled beari
