Hyperbolic geometry and closed bosonic string field theory. Part I. The string vertices via hyperbolic Riemann surfaces

open access: yesJournal of High Energy Physics, 2019
The main geometric ingredient of the closed string field theory are the string vertices, the collections of string diagrams describing the elementary closed string interactions, satisfying the quantum Batalian-Vilkovisky master equation.

Elastic mechanical property hybridization of configuration-varying TPMS with geometric continuity

open access: yesMaterials & Design, 2022
Hybrid design is an effective approach to construct functional mechanical metamaterials. In this study, a periodic hybrid method for the TPMS (triply periodic minimal surface) structures is proposed, maintaining the original surface connectivity and ...

Bubble Growth in Supersaturated Liquids

open access: yesFluids, 2022
Bubble formation and dissolution have a wide range of industrial applications, from the production of beverages to foam manufacturing processes. The rate at which the bubble expands or contracts has a significant effect on these processes. In the current

A uniqueness theorem for the minimal surface equation [PDF]

open access: yesPacific Journal of Mathematics, 1996
In 1991, \textit{P. Collin} and \textit{R. Krust} [Bull. Soc. Math. Fr. 119, 443-462 (1991; Zbl 0754.53013)] proved that if \(u\) satisfies the minimal surface equation in a strip with linear Dirichlet data on two sides, then \(u\) must be a helicoid. In this paper, we give a simpler proof of this result and generalize it.

Non-Fourier heat transfer in a moving longitudinal radiative-convective dovetail fin

open access: yesCase Studies in Thermal Engineering, 2023
The purpose of this research is to estimate the non-Fourier temperature distribution in dovetail fin. The Cattaneo-Vernotte heat model is utilized to estimate heat conduction behavioral patterns in dovetail fin.

Design and Experiments of a Naturally-Ventilated Radiation Shield for Ground Temperature Measurement

open access: yesAtmosphere, 2023
Temperature sensors may produce a measurement error of up to 1 °C because of the influence of solar radiation. In order to obtain a relatively minimal temperature error, a new temperature observation system was proposed in this paper for measuring ...

Algebraic equations and graphics of Bour’s minimal surfaces family

open access: yesJournal of Interdisciplinary Mathematics, 2022
We consider the family of the irreducible algebraic equations of the Bour's minimal surfaces for integers m = 2,3,4 in the three dimensional Euclidean space, and obtain its degrees in cartesian coordinates, classes in inhomogeneous coordinates. We also reveal its integral free representations. Moreover, we visualise the equations of the surface family.
