Current-Mode Grounded-Capacitor Single-Element-Controlled Bandpass and Lowpass Filters

open access: yesActive and Passive Electronic Components, 1995
New circuit configurations for realizing bandpass and iowpass current-mode second-order filters are proposed. Each configuration uses a single first-generation current conveyor, a transconductance amplifier, three grounded capacitors, and two resistors ...

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

Adaptive centre-frequency bandpass state-space digital filters and their l2-sensitivity analysis

open access: yesSICE Journal of Control, Measurement, and System Integration
This paper explores an adaptive centre-frequency bandpass state-space digital filter by expanding a sign algorithm into the gradient-based method. To this end, a simple method for deriving a bandpass state-space digital filter with tuneable centre ...

Higher Order Bandpass Single and Dual Band Frequency Selective Surfaces With Aperture Coupled Patch Resonators

open access: yesIEEE Access
In this article, a low profile aperture coupled single and dual band higher order bandpass frequency selective surface (FSS) is proposed. Initially, a basic patch resonator with L-shape truncated corner is investigated theoretically so that two ...

Highly linear microstrip wideband bandpass filter with switchable notched band for wireless applications [PDF]

open access: yes, 2013
This article presents a highly linear reconfigurable bandpass filter embedded with a switchable notch structure to get a band-notched characteristic at a specified frequency.A single PIN diode (BAP65-02) is used for the purpose of switching the notch. An

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

open access: yesAdvanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

open access: yesAdvanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet
