Measurement of anisotropy of dark matter velocity distribution using directional detection

open access: yesEPJ Web of Conferences, 2018
Although the velocity distribution of dark matter is assumed to be generally isotropic, some studies have found that ~25% of the distribution can have anisotropic components.

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Electrical activation: isotropic vs. anisotropic.

open access: yes, 2018
(a) Isotropic monolayer with Daut = 0.3 and = 0.10 (black sites: PM cells). (b) Electrical activation times (ms) color scale map as a function of node positions for the previously described isotropic monolayer.

Application of the continuum shell finite element SHB8PS to sheet forming simulation using an extended large strain anisotropic elastic–plastic formulation [PDF]

open access: yes, 2012
http://link.springer.com/article/10.1007%2Fs00419-012-0620-xThis paper proposes an extension of the SHB8PS solid–shell finite element to large strain anisotropic elasto-plasticity, with application to several non-linear benchmark tests including sheet ...

Observation of Localized Resonant Phonon Polaritons in Biaxial α‐MoO3 Nanoparticles

open access: yesAdvanced Science
Anisotropic subwavelength particles uniquely combine the strong, tunable response of nanostructures with the exotic properties of anisotropic materials, enabling diverse applications in photonics, biomedicine, and magnetism.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Development law and growth model of dynamic pore water pressure of tailings under different consolidation conditions

open access: yesPLoS ONE, 2022
Tailings dams are in danger of liquefaction during earthquakes. The liquefaction process can be indirectly reflected by the evolution rule of the dynamic pore water pressure.
