Probe Standoff Optimization Method for Phased Array Ultrasonic TFM Imaging of Curved Parts
Sensors, 2021 The reliability of the ultrasonic phased array total focusing method (TFM) imaging of parts with curved geometries depends on many factors, one being the probe standoff.

Frequency-Weighted Model Reduction with Applications to Structured Models [PDF]
, 2007 In this paper, a frequency-weighted extension of a recently proposed model reduction method for linear systems is presented. The method uses convex optimization and can be used both with sample data and exact models.

The Spatial Distribution of the Galactic First Stars II: SPH Approach [PDF]
, 2006 We use cosmological, chemo-dynamical, smoothed particle hydrodynamical simulations of Milky-Way-analogue galaxies to find the expected present-day distributions of both metal-free stars that formed from primordial gas and the oldest star populations.

Cross-sectional and prospective impact of reallocating sedentary time to physical activity on children's body composition. [PDF]
, 2016 BACKGROUND: The amount of time children spend in sedentary behaviours may have adverse health effects. OBJECTIVE: To examine the substitution effects of displacing a fixed duration of sedentary time with physical activity (PA) on children's body ...

Direct Numerical Simulation Tests of Eddy Viscosity in Two Dimensions
, 1994 Two-parametric eddy viscosity (TPEV) and other spectral characteristics of two-dimensional (2D) turbulence in the energy transfer sub-range are calculated from direct numerical simulation (DNS) with 512$^2$ resolution. The DNS-based TPEV is compared with

Magnetic Anisotropy Modulation via van der Waals Gap Engineering in 2D Ferromagnet Fe4GeTe2
Advanced Science, EarlyView.This study demonstrates a new route to control magnetic anisotropy in 2D ferromagnets via van der Waals gap engineering. In Fe4GeTe2, an interface‐induced vdW gap expansion is found to anomalously enhance in‐plane magnetic anisotropy while suppressing the spin reorientation transition.

Asymmetric isolated skyrmions in polar magnets with easy-plane anisotropy
, 2017 We introduce a new class of isolated magnetic skyrmions emerging within tilted ferromagnetic phases of polar magnets with easy-plane anisotropy. The asymmetric magnetic structure of these skyrmions is associated with an intricate pattern of the energy ...
