Low Thermal Conductivity Phase Change Memory Superlattices [PDF]
arXiv, 2022 Phase change memory devices are typically reset by melt-quenching a material to radically lower its electrical conductance. The high power and concomitantly high current density required to reset phase change materials is the major issue that limits the access times of 3D phase change memory architectures.

Investigation of the Flow-Induced Noise and Optimization Design of a Short Tube Throttle Valve [PDF]
Journal of Applied Fluid MechanicsCompared with the globe valves and other on-off valves, cavitation and noise are more severe in the throttle control valve of the refrigerating system due to the higher saturated vapor pressure of the refrigerant. A short tube throttle valve (STTV) is an

The multi-wavelength phase curves of small bodies: Phase coloring [PDF]
A&A 685, A29 (2024)Context. Small bodies change their brightness due to different motives: Rotation along their axis or axes, combined with irregular shapes and/or changing surface properties, or changes in the geometry of observations. In this work, we tackle the problem of Phase curves, which show the change in brightness due to changes in the fraction of illuminated ...

Two-Phase Object-Based Deep Learning for Multi-temporal SAR Image Change Detection [PDF]
arXiv, 2020 Change detection is one of the fundamental applications of synthetic aperture radar (SAR) images. However, speckle noise presented in SAR images has a much negative effect on change detection. In this research, a novel two-phase object-based deep learning approach is proposed for multi-temporal SAR image change detection.

Application of Uniform Matrix Product State to Quantum Phase Transition with a Periodicity Change [PDF]
, 2011 As a method beyond the mean-field analysis, a matrix product state (MPS) with incommensurate periodicity is applied to detect phase transitions accompanied with periodicity change, where the incommensurate MPS is generated by acting local-spin-rotation operators with the incommensurate periodicity on a uniform MPS. As a commensurate/commensurate change,

Reversible Electrochemical Phase Change in Monolayer to Bulk MoTe2 by Ionic Liquid Gating [PDF]
arXiv, 2019 Transition metal dichalcogenides (TMDs) exist in various crystal structures with semiconducting, semi-metallic, and metallic properties. The dynamic control of these phases is of immediate interest for next generation electronics such as phase change memories. Of the binary Mo and W-based TMDs, MoTe2 is attractive for electronic applications because it
