Wide-Field Ca2+ Imaging Reveals Cortical Dynamics Across Propofol Anesthesia and Emergence in Adult Mice

Ziyi Zhang, Lin Ai, Xi Zheng, Jun Zhang et autres

BACKGROUND: Precise control of propofol anesthesia depth is critical for perioperative safety; however, the dynamic reorganization of large-scale cortical functional networks throughout propofol anesthesia and recovery remains incompletely understood. This study employs wide-field imaging to record neuronal activity and functional connectivity across …

Withaferin A Rescues Brain Network Dysfunction and Cognitive Deficits in a Mouse Model of Alzheimer’s Disease

Linda G. Yang, Pu Yin, Han Qin, Zhen Li et autres

Background: Alzheimer’s disease (AD) is the most common dementia, characterized by significant cognitive impairments and neural network dysfunction. Currently, multiple therapeutic strategies are being developed to design effective anti-AD drugs. Among them, Withaferin A (WA), a natural steroidal lactone extracted from Withania …

2.5 GHz Low-Loss and Wideband Surface Acoustic Wave Filter Based on AL/128°YX-LiNbO3

Weidong Wang, H. B. Teng, Fei Wang, Yun Zhou et autres

Abstract A 128°YX-LiNbO3-based low-insertion-loss and high-frequency surface acoustic wave (SAW) filter was proposed using COMSOL Multiphysics. The spurious response was suppressed by changing the electrode thickness, reflector period, and reflector structure, after optimization. First, the thickness of the electrode was increased to …

Phonon assisted intersubband transitions in step quantum well structures

H. B. Teng, Jiangning Sun, G.I. Haddad, Michael A. Stroscio et autres

We evaluate effects of heterointerfaces on optical phonon modes and phonon assisted electron intersubband transition rates in step quantum well structures for intersubband lasers. Various phonon modes and electron–phonon interaction Hamiltonians, including the interface modes, confined longitudinal-optical modes, and half space modes …

Electron-interface phonon interaction in multiple quantum well structures

Jiangning Sun, H. B. Teng, George I. Haddad, Michael A. Stroscio

Intersubband relaxation rates due to electron interactions with the interface phonons are evaluated for multiple quantum well structures designed for step quantum well lasers operating at mid-infrared to submillimetre wavelengths. The interface phonon modes and electron-phonon interaction Hamiltonians for the structures are …

lntersubband Relaxation in Step QuantumWell Structures

Jiangning Sun, H. B. Teng, George I. Haddad, Michael A. Stroscio et autres

Intersubband relaxation due to electron interactions with the localized phonon modes plays an important role for population inversion in quantum well laser structures designed for intersubband lasers operating at mid‐infrared to submillimeter wavelengths. In this work, intersubband relaxation rates between subbands in …
