Simultaneous Guidance of Surface Acoustic and Surface Optical Waves in Phoxonic Crystal Slabs

Crystals, 2017
Phoxonic crystals, which exhibit simultaneous phononic and photonic bandgaps, are promising artificial materials for optomechanical and acousto-optical devices.

Slow-Wave Transmission Line Transformers/Baluns [PDF]

, 2012
The design and analysis of a miniaturized transmission line transformer/balun for RF applications is proposed. A novel right-handed slow-wave line using three-dimensional periodic substrate metallization is proposed, where each unit cell is made up of a ...

Progress in Mathematical Modeling of Gastrointestinal Slow Wave Abnormalities

Frontiers in Physiology, 2018
Gastrointestinal (GI) motility is regulated in part by electrophysiological events called slow waves, which are generated by the interstitial cells of Cajal (ICC).

Optogenetic targeting of astrocytes restores slow brain rhythm function and slows Alzheimer’s disease pathology

Scientific Reports, 2023
Patients with Alzheimer’s disease (AD) exhibit non-rapid eye movement (NREM) sleep disturbances in addition to memory deficits. Disruption of NREM slow waves occurs early in the disease progression and is recapitulated in transgenic mouse models of beta ...

An infant sleep electroencephalographic marker of thalamocortical connectivity predicts behavioral outcome in late infancy

NeuroImage, 2023
Infancy represents a critical period during which thalamocortical brain connections develop and mature. Deviations in the maturation of thalamocortical connectivity are linked to neurodevelopmental disorders. There is a lack of early biomarkers to detect

Enhancing uterine contraction detection through novel EHG signal processing: a pilot study leveraging the relationship between slow and fast wave components to improve signal quality and noise resilience

Frontiers in Physiology
Uterine contractions, driven by complex electrical activities within the uterine smooth muscle cells, play a critical role in labor and delivery. Various techniques, including EHG and EMMI, have been developed to record and image uterine electrical ...

Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

eLife, 2017
Spontaneous slow oscillation-associated slow wave activity represents an internally generated state which is characterized by alternations of network quiescence and stereotypical episodes of neuronal activity - slow wave events.

Anaesthesia by intravenous propofol reduces the incidence of intra-operative gastric electrical slow-wave dysrhythmias compared to isoflurane

Scientific Reports, 2023
Gastric motility is coordinated by bioelectrical slow-wave activity, and abnormal electrical dysrhythmias have been associated with nausea and vomiting. Studies have often been conducted under general anaesthesia, while the impact of general anaesthesia ...

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]

, 2010
Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
