The study of crystal and magnetic properties of MnNi0.85Fe0.15Ge

Nukleonika, 2015
Magnetic and Mössbauer measurements were performed for MnNi0.85Fe0.15Ge. The Mössbauer data indicate that Fe atoms in MnNi0.85Fe0.15Ge are randomly distributed over two types of metal sites in hexagonal structure.

Reentrant hexagonal Turing structures

Physics Letters A, 1992
Abstract A new structural transition from stripes to hexagons is reported for the two-dimensional Brusselator model. Its existence is explained by the properties of the quadratic nonlinear coupling.

Grid Cell Hexagonal Patterns Formed by Fast Self-Organized Learning within Entorhinal Cortex [PDF]

, 2009
Grid cells in the dorsal segment of the medial entorhinal cortex (dMEC) show remarkable hexagonal activity patterns, at multiple spatial scales, during spatial navigation. How these hexagonal patterns arise has excited intense interest. It has previously

An Occupancy Information Grid Model for Path Planning of Intelligent Robots

ISPRS International Journal of Geo-Information, 2022
Commonly used robot map models include occupancy grid maps, topological maps, and semantic maps. Among these, an occupancy grid map is mainly represented as a quadrilateral grid. This paper proposes an occupancy information grid for intelligent robots by

Structural Characterization of Hexagonal Braiding Architecture Aided by 3D Printing

MATEC Web of Conferences, 2018
Hexagonal braiding method has the advantages of high shape compatibility, interlacing density and high volume fraction. Based on hexagonal braiding method, a hexagonal preform was braided.

Fermi surface and order parameter driven vortex lattice structure transitions in twin-free YBa2Cu3O7 [PDF]

, 2009
We report on small-angle neutron scattering studies of the intrinsic vortex lattice (VL) structure in detwinned YBa2Cu3O7 at 2 K, and in fields up to 10.8 T.

Hexagonal structures in 2D Navier–Stokes flows [PDF]

Communications in Partial Differential Equations, 2022
Geometric structures naturally appear in fluid motions. One of the best known examples is Saturn's Hexagon, the huge cloud pattern at the level of Saturn's north pole, remarkable both for the regularity of its shape and its stability during the past decades.

Evaluation of the Holland model of the professional interests in Croatia and Serbia [PDF]

Psihologija, 2007
The RIASEC structure has been tested in Croatian and Serbian sample. The Holland's Self-directed Search was applied on a sample of 746 high-school pupils (384 coming from Croatia and 362 from Serbia).
