Two types of multiweighted coupled memristive neural networks (CMNNs) with adaptive couplings are introduced in this article, and the fixed-time passivity (FXTP) and fixed-time synchronization (FXTS) of such networks are considered. First, under the developed adaptive scheme, a sufficient condition to guarantee the FXTP for multiweighted CMNNs with adaptive couplings is obtained. Second, the FXTP, fixed-time input-strict passivity and fixed-time output-strict passivity for multiweighted CMNNs with adaptive couplings and coupling delays are investigated by devising an appropriate state feedback controller. Third, applying the Lyapunov functional method, it establishes the FXTS criteria for the two kinds of networks presented. Finally, numerical examples are provided to demonstrate the effectiveness of the derived results.

Background: Cutting-edge ultrasensitive immunoassay platforms have unveiled the potential of blood-based biomarkers, offering detection at low fg/mL levels for early neurodegenerative disorder prognosis, screening, and therapeutic monitoring. Current immunoassays, such as single molecule array (SIMOA) and mesoscale multi-array (MSD), face limited adoption due to their reliance on specialized equipment. Additionally, they require immobilization of probe reagents and a washing process, demanding tens of thousands of proteins to achieve the Limit of Detection (LOD), leading to the requirement of high sample volume and high affinity antibodies for fg/mL sensitivity.

Neuromodulators have major influences on the regulation of neural circuit activity across the nervous system. Nitric oxide (NO) has been shown to be a prominent neuromodulator in many circuits and has been extensively studied in the retina. Here, it has been associated with the regulation of light adaptation, gain control, and gap junctional coupling, but its effect on the retinal output, specifically on the different types of retinal ganglion cells (RGCs), is still poorly understood.

Given that communication plays an intricate role in establishing and sustaining relationships, svPPA can impact relationships, including those with spouses, in a manner that can only be understood by firsthand experiences. This study aimed to describe a spouse's experiences of communicating with an individual with svPPA along with the role of communication supports and expectations for speech-language therapy.

Background: Synapse loss represents the closest correlate of cognitive decline in Alzheimer's Disease (AD). Standard microscopy, due to increased diffraction of light with tissue depth, imposes a limit on axial resolution extending to ∼ 700nm. Array tomography (AT), developed by Micheva & Smith (2007), extends this axial limit via physical sectioning of resin-embedded tissue into ribbons of 70nm contiguous sections that are serially imaged and reconstructed into 3D volumes; thus, allowing for nanometric synaptic puncta to be resolved at the mesoscale.

Background: Astrocytes are a glial cell type responsible for many protective functions in the brain. While they are primarily recognized for regulating synaptic activity, they're also essential for maintaining the neurovascular unit, and cerebral hyperperfusion during metabolic demand. Calcium signaling has been identified as a regulatory process for these functions.
