A novel 2nd-order bandpass MFSS filter with miniaturized structure

open access: yesAIP Advances, 2015
In order to effectively obtain a miniaturized structure and good filtering properties, we propose a novel 2nd-order bandpass metamaterial frequency selective surface (MFSS) filter which contains two capacitive layers and one inductive layer, where there ...

Versatile Tunable Voltage-Mode Biquadratic Filter and Its Application in Quadrature Oscillator

open access: yesSensors, 2019
This paper presents a versatile tunable voltage-mode biquadratic filter with five inputs and three outputs. The proposed filter enjoys five single-ended output operational transconductance amplifiers (OTAs) and two grounded capacitors.

Magnetoelectric microwave bandpass filter

open access: yesElectronics Letters, 2006
An electric field tunable microwave bandpass filter based on ferromagnetic resonance (FMR) in a bilayer of yttrium iron garnet and lead zirconate titanate has been designed and characterised. The filter tunability is accomplished through magnetoelectric coupling that manifests as a shift in the FMR.

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

open access: yesAdvanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Design of Quad-Channel Diplexer and Tri-band Bandpass Filter Based on Multiple-Mode Stub-Loaded Resonators [PDF]

open access: yesRadioengineering, 2019
Multiple-mode stub-loaded resonator with quad channel diplexer and tri-band bandpass filter are presented and analyzed theoretically in this paper. The multi-mode stub-loaded resonator employs the basic structure of a triple mode resonator.

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

open access: yesAdvanced Science, EarlyView.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.
