PRACTICAL DESIGN APPROACH FOR TRAPEZOIDAL MODULATION OF A RADIO-FREQUENCY QUADRUPOLE



Infinite distance networks in field space and charge orbits

Abstract The Swampland Distance Conjecture proposes that approaching infinite distances in field space an infinite tower of states becomes exponentially light.We study this conjecture for the complex structure moduli space of Calabi-Yau manifolds.In this context, we uncover significant structure within the proposal by showing that there is a rich s

A modified surgical approach for hard and soft tissue reconstruction of severe periimplantitis defects: laser-assisted periimplant defect regeneration (LAPIDER)

Abstract Background The main problem in periimplantitis is often the combination of severe periimplant bone loss with a contaminated implant surface and an insufficient soft tissue situation.Classic surgical concepts with crestal access to the bony defect and debridement of the surface most often lead to partial defect regeneration and a soft tissu
