A bstract We elaborate on recent results regarding the self-consistency of de Sitter vacua in LARGE-volume scenario type IIB string theory. In particular, we analyze to what extent control over warping, curvature and g s corrections depends topology orientifold/brane data a compactification. compute general bound magnitude these which strongly constrains D3 tadpole. The minimally required tadpo...

A bstract Type IIB flux vacua based on Landau-Ginzburg models without Kähler deformations provide fully-controlled insights into the non-geometric and strongly-coupled string landscape. We show here that supersymmetric configurations at Fermat point of 1 9 model, which were found long-time ago to saturate orientifold tadpole, leave a number massless fields, however are not all flat directions s...

BACKGROUND There have been reports of serious complications associated with pedicle screw fixation, including nerve root injuries caused by accidental screw insertion. We have developed a new system of lumbar spinal instrumentation that we call Tadpole system. The purposes of this report were to show the results of a biomechanical study and the short-term outcome of a clinical study, as well as...

The tadpole cancellation in the unoriented Liouville theory is discussed. Using two different methods — the free field method and the boundary-crosscap state method, we derive one-loop divergences. Both methods require two D1-branes with the symplectic gauge group to cancel the orientifold tadpole divergence. However, the finite part left is different in each method and this difference is studi...

Some organisms have a remarkable ability to heal wounds without scars and to regenerate complex tissues following injury. By gaining a more complete understanding of the biological mechanisms that promote scar-free healing and tissue regeneration, it is hoped that novel treatments that can enhance the healing and regenerative capacity of human patients can be found. In the present article, we b...
