Acoustoelectric effects in very high-mobility p-SiGe/Ge/SiGe heterostructure [PDF]

Journal of Applied Physics, 2009
Measurement results of the acoustoelectric effects [surface acoustic waves (SAW) attenuation and velocity] in a high-mobility p-SiGe/Ge/SiGe structure are presented. The structure was low-energy plasma-enhanced chemical vapor deposition grown with a two-dimensional (2D) channel buried in the strained Ge layer.

Development of Artificial Intelligence for Quantitative Assessment of Nasal Inflammatory Cytology in Chronic Rhinitis by Whole‐Slide Images

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinitis (CR) is currently recognized as a syndrome that manifests in different phenotypes. We aimed to establish an artificial intelligence system (quantitative assessment of nasal inflammatory cytology, QANIC) on the basis of whole‐slide images (WSIs) to enable quantitative assessment of nasal inflammatory cells.

Ballistic one-dimensional holes with strong g-factor anisotropy in germanium [PDF]

, 2018
We report experimental evidence of ballistic hole transport in one-dimensional quantum wires gate-defined in a strained SiGe/Ge/SiGe quantum well. At zero magnetic field, we observe conductance plateaus at integer multiples of 2e2/h.

Local Specific IgE Levels Can Predict and Monitor the Therapeutic Response to Subcutaneous Immunotherapy With House Dust Mite

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Identifying predictive and monitoring biomarkers for allergen immunotherapy response is crucial for enhancing clinical efficacy. This study aims to investigate the systemic and local levels of immunoglobulins and identify potential biomarkers in house dust mite (HDM) allergic rhinitis (AR) patients who are undergoing subcutaneous ...

Metal-Insulator Transition and Spin Degree of Freedom in Silicon 2D Electron Systems

, 1999
Magnetotransport in 2DES's formed in Si-MOSFET's and Si/SiGe quantum wells at low temperatures is reported. Metallic temperature dependence of resistivity is observed for the n-Si/SiGe sample even in a parallel magnetic field of 9T, where the spins of ...
