Twist-driven wide freedom of indirect interlayer exciton emission in MoS2/WS2 heterobilayers

open access: yesCell Reports Physical Science, 2021
Summary: Theoretical and first-principal studies involving twisted two-dimensional (2D) heterobilayer transition metal dichalcogenides (TMDs) predict interlayer exciton (ILE) emission energy amplitudes (the energy difference between the lowest and the ...

The Optimization of Savonius Helix Wind Turbine Cut-in Speed with the Variation of Blades-twist Rotor and Number of Blades

open access: yesJIPTEK: Jurnal Ilmiah Pendidikan Teknik dan Kejuruan, 2023
Wind turbines are typically classified as Horizontal Axis Wind Turbines (HAWT) or Vertical Axis Wind Turbines (VAWT). VAWT has a superior ability to accelerate from rest to rotation than HAWT, allowing it to rotate the rotor even when the wind speed is ...

Convective layered flows of a vertically whirling viscous incompressible fluid. Velocity field investigation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
This article discusses the solvability of an overdetermined system of heat convection equations in the Boussinesq approximation. The Oberbeck-Boussinesq system of equations, supplemented by an incompressibility equation, is overdetermined.

Four-domain twisted vertically aligned liquid crystal pixels using microrubbing [PDF]

open access: yesApplied Physics Letters, 2005
Microrubbing (μ-rubbing) technique is used to create four-domain twisted vertically aligned liquid crystal pixels for wide viewing angle displays. A metallic sphere of 1 mm diameter is used to locally rub a homeotropic polyimide surface to create a four-domain pixel. We use μ-rubbing to accurately control the surface pretilt angle of the liquid crystal

Hybrid bounds for twisted L-functions [PDF]

open access: yes, 2008
The aim of this paper is to derive bounds on the critical line Rs 1/2 for L- functions attached to twists f circle times chi of a primitive cusp form f of level N and a primitive character modulo q that break convexity simultaneously in the s and q ...

Existence of a twist angle intrinsic to the reference orbit in circular accelerators

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2000
In a circular accelerator, a horizontal-vertical coupling can occur as a purely geometrical effect, in the absence of any coupling device (skew-quadrupole magnets, etc.).

Effect of Allowable Vertical Load and Length/Diameter Ratio (L/D) on Behavior of Pile Group Subjected to Torsion

open access: yesJournal of Engineering, 2023
Some structures such as tall buildings, offshore platforms, and bridge bents are subjected to lateral loads of considerable magnitude due to wind and wave actions, ship impacts, or high-speed vehicles.

Aeroelastic analysis of straight-bladed vertical axis wind turbine blade [PDF]

open access: yesFME Transactions, 2022
To prevent flutter phenomena in a wind turbine, minimize vibration and increase the blades' life, a systematic analysis is required to investigate the effects between the cyclic aerodynamic loads and the structural performance of the turbine.

Surfactant-induced gradients in the three-dimensional Belousov-Zhabotinsky reaction [PDF]

open access: yes, 2011
Scroll waves are prominent patterns formed in three-dimensional excitable media, and they are frequently considered highly relevant for some types of cardiac arrhythmias.
