Discrete Wilson Lines in F-Theory by Volker Braun

“…The base manifolds used are a toric Fano variety and a smooth toric threefold coming from a reflexive polyhedron. The discriminant locus of the elliptically fibered Calabi-Yau fourfold can be chosen such that one irreducible component is not simply connected (namely, an Enriques surface) and supports a non-Abelian gauge theory.…”

Beamforming for Rotated 3D Multipanel Array Structures for 5G NR MIMO Transmission by Hyukjun Lee, Wonjae Ryu, Wonjin Sung, Jonghyun Park

“…In this paper, we propose an array structure to transmit signals over the three-dimensional (3D) space in an isotropic fashion for all types of UEs in ground, aerial, and high-rise building locations, by employing panels on surfaces of a polyhedron. We further derive exact beamforming equations for the proposed array and show the resulting beams provide improved receiver performance over the exiting conventional beamforming. …”

Optimization of Indirect Fracturing Process Parameters Based on Mechanical Properties of Fractured and Low-Permeability Coal by Wenfeng Yuan, Xigui Zheng, Niaz Muhammad Shahani

“…This paper focuses on solving the above problems by focusing on discontinuities and plastic characteristics of soft coals. Voronoi polyhedron was used to simulate the discontinuities of coal, and the constitutive relations of ductile fracture-seepage and elastoplastic damage-seepage are, respectively, given to the discontinuities and coal matrix. …”

Results of the metallographic study of blacksmithing items from the excavations at Podgory V settlement on the Samara Bend by Kondrashin Vitaly V., Myshkin Vladimir N.

“…The sample of ferrous metal artifacts subjected to metallographic study amounted to 21 pieces: knives, awls, sickle, arrowhead, earring with a polyhedron, fixing ring, fire lighter and plate. The metallographic collection included rod-shaped objects, some of which were identified as semi-finished products (metal raw material). …”

Protein-DNA interactions: statistical analysis of interatomic contacts in major and minor grooves by A. A. Anashkina, E. N. Kuznetsov, A. V.  Batianovskii, L. A. Uroshlev, V. G. Tumanyan, N. G. Esipova

“…The method unambiguously defines contacts between atoms without any parameters, and characterizes each contact by the distance between atoms and the contact area, which is determined by the corresponding face of the Voronoi polyhedron. It was shown that most contacts are formed between the protein atoms and the sugarphosphate backbone of the DNA (72.9 %). …”
