Aquadi-n-butyl(5-methylpyrazine-2-carboxylato)tin(IV) methanol solvate
Acta Crystallographica Section E, 2008 In the monomeric title compound, [Sn(C4H9)2(C6H5N2O2)2(H2O)]·CH3OH, the Sn atom is seven-coordinate, displaying a distorted pentagonal bipyramidal SnC2N2O3 geometry with the two C atoms in the axial sites. In the crystal structure, intermolecular O&#

Milnor fibers and Links of Local Complete Intersections [PDF]
arXiv, 2014 We discuss and prove a number of cohomological results for Milnor fibers, real links, and complex links of local complete intersections with singularities of arbitrary dimension.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal

Link Crossing Number is NP-hard [PDF]
arXiv, 2019 We show that determining the crossing number of a link is NP-hard. For some weaker notions of link equivalence, we also show NP-completeness.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Studies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of

Intercusp Geodesics and Cusp Shapes of Fully Augmented Links [PDF]
arXiv, 2018 We study the geometry of fully augmented link complements in $S^3$ by looking at their link diagrams. We extend the method introduced by Thistlethwaite and Tsvietkova to fully augmented links and define a system of algebraic equations in terms of parameters coming from edges and crossings of the link diagrams.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study evaluates a novel cone‐beam computed tomography (CBCT) imaging solution integrated onto a conventional C‐arm linear accelerator (linac) with increased gantry speed. The purpose is to assess the impact of improved imaging hardware and reconstruction algorithms on image quality.
