Thin electron‐scale layers at the magnetopause [PDF]

Geophysical Research Letters, 2004
We use data from the four Cluster satellites to examine the microphysics of a thin electron‐scale layer discovered on the magnetospheric side of the magnetopause. Here the ion and electron motions are decoupled in a layer about 20 km (a few electron scales) wide, including currents and strong electric fields.

Sub-unit cell layer-by-layer growth of Fe3O4, MgO, and Sr2RuO4 thin films

, 2002
The use of oxide materials in oxide electronics requires their controlled epitaxial growth. Recently, it was shown that Reflection High Energy Electron Diffraction (RHEED) allows to monitor the growth of oxide thin films even at high oxygen pressure ...

Reading a GEM with a VLSI pixel ASIC used as a direct charge collecting anode [PDF]

, 2004
In MicroPattern Gas Detectors (MPGD) when the pixel size is below 100 micron and the number of pixels is large (above 1000) it is virtually impossible to use the conventional PCB read-out approach to bring the signal charge from the individual pixel to ...

Optimized Time–Frequency Analysis for Induction Motor Fault Detection Using Hybrid Differential Evolution and Deep Learning Techniques

International Journal of Adaptive Control and Signal Processing, EarlyView.
Workflow of the parameter optimization process for ITSC fault detection, applying Differential Evolution optimization and the Smooth Pseudo Wigner‐Ville Distribution for signal processing. The optimized parameters are then used in the failure identification pipeline, which combines the signal processing with a YOLO‐based architecture for fault severity

Assembly-induced microwave band resonance in gold nanoparticles-based ultrathin and flexible spoof localized surface plasmon

Materials & Design, 2021
Spoof LSP (Localized Surface Plasmon) is a great advance in metamaterials, expanding the LSP resonance from optical band into microwave band. It will yield amazing outcomes by integration with flexible electronics, wearable electronics and nanophotonics.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Cooling of Electrons in a Silicon Inversion Layer [PDF]

Physical Review Letters, 2001
Low temperature cooling of two-dimensional electrons in silicon-metal-oxide semiconductor field effect transistors is studied experimentally and found to be more effective than expected from the bulk electron-phonon coupling in silicon. The extracted heat transfer rate to phonons depends cubically on electron temperature, suggesting that piezoelectric ...

Biomimetic flow-sensor arrays based on the filiform hairs on the cerci of crickets [PDF]

, 2007
In this paper we report on the latest developments in biomimetic flow-sensors based on the flow sensitive mechano-sensors of crickets. Crickets have one form of acoustic sensing evolved in the form of mechanoreceptive sensory hairs.
