Quasilinear theory of the 2D Euler equation [PDF]

, 2000
We develop a quasilinear theory of the 2D Euler equation and derive an integro-differential equation for the evolution of the coarse-grained vorticity.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Lagrangian modeling of bedload movement via the impulse entrainment method

E3S Web of Conferences, 2018
At low shear stresses merely above incipient conditions, the characteristic travel patterns of bedload particles remain difficult to predict due to intermittent movement.

Relativistically generated asymmetry in the missing momentum distribution from the $(e,e'p)$ reaction

, 1994
We calculate the asymmetry in the missing-momentum distribution from the $(e,e'p)$ reaction in a relativistic formalism. Longitudinal and transverse response functions are evaluated in parallel kinematics as a function of the three-momentum transfer to ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

K^+ momentum spectrum from (K^-,K^+) reactions in intranuclear cascade model

, 1996
In a framework of intranuclear cascade (INC) type calculation, we study a momentum spectrum in reactions \KK at a beam momentum of 1.65 GeV/c. INC model calculations are compared with the relativistic impulse approximation (RIA) calculations to perform ...

Quasi Free 238U (e,e'f)-Cross Section in Macroscopic-Microscopic Approach [PDF]

, 2002
We present the result of a theoretical study of inclusive quasi free electrofission of $^{238}$U. The off-shell $ $cross sections for the quasi free reaction stage have been calculated within the Plane Wave Impulse Approximation (PWIA), using a ...
