Advanced Science, EarlyView.Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

Detection of Normal and Periodic Breathing in Human Breathing Patterns
This work is a bachelor’s thesis in physics, contributing to the field of biomedical physics by presenting computational methods for classifying normal breathing signals, periodic breathing signals and their respective signal segments. Using 15 clinically measured respiratory signals, the study applies a range of signal processing and time series ...

Advanced Science, EarlyView.A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

Advanced Science, EarlyView.Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Sleep-induced periodic breathing and apnea: a theoretical study
, 1991 To elucidate the mechanisms that lead to sleep-disordered breathing, we have developed a mathematical model that allows for dynamic interactions among the chemical control of respiration, changes in sleep-waking state, and changes in upper airway ...

Advanced Science, EarlyView.Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

Altitude-Associated Central Apnea in Continuous Positive Airway Pressure Therapy
Sleep ScienceIntroduction At high altitudes, hypobaric hypoxia leads to central apneas in both healthy adults and patients with obstructive sleep apnea. This condition correlates with intermittent desaturation and disruption of sleep.

Advanced Science, EarlyView.Ocular hypertension induces early hyperactivity in inner retinal inhibitory circuitry before substantial retinal ganglion cell loss. Sustained pharmacological inhibition of GABAergic/glycinergic neurotransmission and Vgat‐targeted Lin28 expression suppress this hyperactivity and improve RGC survival without reducing intraocular pressure. These findings
