Planar and non-planar solidification Planar and non-planar solidification of optically organized smectic films [PDF]

arXiv, 2010
We present in this letter an original freezing process yielding remarkably homogeneous films of chiral smectics. This optical homogeneity is observed on planar films as well as on films exhibiting various complex three-dimensional shapes.

On the Planar Edge-Length Ratio of Planar Graphs [PDF]

arXiv, 2019
The edge-length ratio of a straight-line drawing of a graph is the ratio between the lengths of the longest and of the shortest edge in the drawing. The planar edge-length ratio of a planar graph is the minimum edge-length ratio of any planar straight-line drawing of the graph.

Planar chiral metasurfaces with maximal and tunable chiroptical response driven by bound states in the continuum [PDF]

Nature Communications, 2021
Optical metasurfaces with high quality factors (Q-factors) of chiral resonances can boost substantially light-matter interaction for various applications of chiral response in ultrathin, active, and nonlinear metadevices. However, current approaches lack

Quantum approximate optimization of non-planar graph problems on a planar superconducting processor [PDF]

Nature Physics, 2020
Faster algorithms for combinatorial optimization could prove transformative for diverse areas such as logistics, finance and machine learning. Accordingly, the possibility of quantum enhanced optimization has driven much interest in quantum technologies.

(k, p)-Planarity: A Relaxation of Hybrid Planarity [PDF]

Theoretical Computer Science, 2018
We present a new model for hybrid planarity that relaxes existing hybrid representations. A graph $G = (V,E)$ is $(k,p)$-planar if $V$ can be partitioned into clusters of size at most $k$ such that $G$ admits a drawing where: (i) each cluster is associated with a closed, bounded planar region, called a cluster region; (ii) cluster regions are pairwise ...

Planar arcs [PDF]

Journal of Combinatorial Theory, Series A, 2018
Let $p$ denote the characteristic of ${\mathbb F}_q$, the finite field with $q$ elements. We prove that if $q$ is odd then an arc of size $q+2-t$ in the projective plane over ${\mathbb F}_q$, which is not contained in a conic, is contained in the intersection of two curves, which do not share a common component, and have degree at most $t+p^{\lfloor ...

Factors modulating 99mTc‐MAA planar lung dosimetry for 90Y radioembolization

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To investigate the accuracy and biases of predicted lung shunt fraction (LSF) and lung dose (LD) calculations via 99mTc‐macro‐aggregated albumin (99mTc‐MAA) planar imaging for treatment planning of 90Y‐microsphere radioembolization.

Feasibility of radical cardiac‐sparing, treatment planning strategies for patients with locally advanced, non‐small cell lung cancer

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose A set of treatment planning strategies were designed and retrospectively implemented for locally advanced, non‐small cell lung cancer (NSCLC) patients in order to minimize cardiac dose without compromising target coverage goals. Methods Retrospective analysis was performed for 20 NSCLC patients prescribed to 60–66 Gy that received a ...
