An optoelectronic artificial synapse device has been established based on ZnO/Zn-HQ nanoporous hybrid thin films by atomic/molecular layer deposition. This unique nanoporous microstructure in devices significantly enhances the optoelectronic response and relaxation time, enabling important biosynaptic functions under optical stimuli, such as Pavlov's dog experiment and pattern recognition. The mechanism of ionization-deionization of oxygen vacancies has been proposed for this device.

The rapid advancements in the field of artificial intelligence have intensified the urgent need for low-power, high-speed artificial synaptic devices. Here, a near-infrared (NIR) artificial synaptic device is successfully realized based on pristine InGaAs nanowires (NWs), which achieves a paired-pulse facilitation (PPF) of up to 119%. Additionally, a postsynaptic current (PSC) in memory storage behavior has been implemented by applying different voltage pulses along with continuous illumination of 1064 nm NIR light due to the memristor characteristics of the device.

Contactless human-machine interfaces (C-HMIs) are revolutionizing artificial intelligence (AI)-driven domains, yet face application limitations due to narrow sensing ranges, environmental fragility, and structural rigidity. To address these obstacles, we developed a flexible photonic C-HMI (Flex-PCI) using flexible visible-blind near-infrared organic photodetectors. In addition to its unprecedented performance across key metrics, including broad detection range (0.

Purpose: Uncertainty persists regarding the optimal mode of mechanical ventilation for laparoscopic perioperative periods. Electrical impedance tomography (EIT) is an effective tool for monitoring and guiding lung-protective ventilation. This study aimed to compare the effects of pressure-controlled ventilation-volume guaranteed (PCV-VG) and volume-controlled ventilation (VCV) on pulmonary ventilation during laparoscopic surgery.
