Generation of nondiffracting radial carpet-lattice beams by using an extended Durnin’s setup
Journal of the European Optical Society-Rapid PublicationsIn the past, the researchers have generated radial carpet beams, a type of 2D optical lattice with polar symmetry. However, the classical radial carpet beams expand slowly as they propagate, that is, they are not nondiffracting beams.

Radial symmetry of minimizers to the weighted Dirichlet energy
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2020 AbstractWe consider the problem of minimizing the weighted Dirichlet energy between homeomorphisms of planar annuli. A known challenge lies in the case when the weightλdepends on the independent variablez. We prove that for an increasing radial weightλ(z) the infimal energy within the class of all Sobolev homeomorphisms is the same as in the class of ...

Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Regularity of the interface for the porous medium equation
Electronic Journal of Differential Equations, 2000 We establish the interface equation and prove the C-infinity regularity of the interface for the porous medium equation whose solution is radial symmetry.

DETECTION OF CITRUS TREES FROM UAV DSMS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 This paper presents an automated approach to detect citrus trees from digitals surface models (DSMs) as a single source. The DSMs in this study are generated from Unmanned Aerial Vehicles (UAVs), and the proposed approach first considers the symmetric ...

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment
Advanced Engineering Materials, EarlyView.This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

On the asymptotic behavior and radial symmetry of positive solutions of semilinear elliptic equations in R n II. Radial symmetry [PDF]
Archive for Rational Mechanics and Analysis, 1992 [For part I see the preceding entry.] In that paper the authors use sharp asymptotic behavior estimates and the ``moving plane'' technique in order to prove the symmetry of the solutions of a large class of semilinear equations in \(\mathbb{R}^ n\).
