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...

<p style='text-indent:20px;'>Partial differential equations on networks have been widely investigated in the last decades view of their application to quantum mechanics (Schrödinger type equations) or analysis flexible structures (wave equations). Nevertheless, very few results are available for diffusive models despite an increasing demand arising from life sciences such as neurobiology....

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...

let $r$ be a commutative ring with identity. let $g(r)$ denote the maximal graph associated to $r$, i.e., $g(r)$ is a graph with vertices as the elements of $r$, where two distinct vertices $a$ and $b$ are adjacent if and only if there is a maximal ideal of $r$ containing both. let $gamma(r)$ denote the restriction of $g(r)$ to non-unit elements of $r$. in this paper we study the various graphi...
