Electromechanical coupling in polaronic ceria [PDF]
JPhys EnergyOxygen-defective metal oxides like cerium oxides exhibit giant electrostriction and field-induced piezoelectricity due to a dynamic electrosteric interplay between oxygen defects, ${\text{V}}_{\text{O}}^{ \cdot \cdot }$ , and the fluorite lattice.

Electromechanical coupling across the gastroduodenal junction. [PDF]
Acta Physiol (Oxf)Abstract The gastroduodenal junction is uniquely capable of regulating digestive functions in the gastrointestinal system. The pyloric sphincter, which demarcates the stomach from the small intestine, acts as a mechanical and electrical barrier, isolating each organ, thus enabling independent behaviors that are critical for proper ...

Inactivation of the Kv2.1 channel through electromechanical coupling. [PDF]
Nature, 2023 AbstractThe Kv2.1 voltage-activated potassium (Kv) channel is a prominent delayed-rectifier Kv channel in the mammalian central nervous system, where its mechanisms of activation and inactivation are critical for regulating intrinsic neuronal excitability1,2.

Atrial Electromechanical Coupling in Patients with Lichen Planus. [PDF]
Korean Circ J, 2016 A chronic inflammatory disease, lichen planus may cause disturbance of atrial electromechanical coupling and increase the risk of atrial fibrillation. The aim of this study was to evaluate atrial electromechanical delay with both electrocardiography (ECG) and echocardiography in patients with lichen planus (LP).Seventy-two LP patients (43 males [59.7%],
