    Effects of Active and Passive Control Techniques on Mach 1.5 Cavity Flow Dynamics by Selin Aradag, Kubra Asena Gelisli, Elcin Ceren Yaldir

    Published 2017-01-01
    “…Several techniques are used for passive control including using a cover plate to separate the flow dynamics inside and outside of the cavity, trailing edge wall modifications, such as inclination of the trailing edge, and providing curvature to the trailing edge wall. The results of active and passive control techniques are compared with the baseline case in terms of pressure fluctuations, sound pressure levels at the leading edge, trailing edge walls, and cavity floor and in terms of formation of the flow structures and the results are presented. …”

    Universal bounds on CFT Distance Conjecture by Hirosi Ooguri, Yifan Wang

    Published 2024-12-01
    “…In particular, our bounds on α indicate that the emergence of exponentially light states is inevitable as the moduli field corresponding to t rolls beyond the Planck scale along the steepest path and that this phenomenon can begin already at the curvature scale of the bulk geometry. We also comment on implications of our bounds for gravity in asymptotically flat spacetime by taking the flat space limit and compare with the Sharpened Distance Conjecture.…”

    Treatment of Thoracolumbar Spinal Infections through Anterolateral Approaches Using Expandable Titanium Mesh Cage for Spine Reconstruction by Tarantino Roberto, Marruzzo Daniele, Cappelletti Martina, De Giacomo Tiziano, Delfini Roberto

    Published 2012-01-01
    “…Surgery is also fundamental in helping to recover vital functions and in restoring as much as possible the correct curvature of the rachises. The use of an anterolateral approach is dictated by the necessity of obtaining 360° stability as well as by the need to clear away extensive infections, which are not always reachable using a posterior approach.…”
