Real-Time Unsupervised Learning and Image Recognition via Memristive Neural Integrated Chip Based on Negative Differential Resistance of Electrochemical Metallization Cell Neuron Device.

Spiking neurons are essential for building energy-efficient biomimetic spatiotemporal systems because they communicate with other neurons using sparse and binary signals. However, the achievable high density of artificial neurons having a capacitor for emulating the integrate function of biological neurons has a limit. Furthermore, a low-voltage operation (<1.

N-Cadherin promotes cardiac regeneration by potentiating pro-mitotic β-Catenin signaling in cardiomyocytes.

Adult human hearts exhibit limited regenerative capacity. Post-injury cardiomyocyte (CM) loss can lead to myocardial dysfunction and failure. Although neonatal mammalian hearts can regenerate, the underlying molecular mechanisms remain elusive.

Understanding the Dynamics Governing Electrocatalytic Hydrodeoxygenation of Lignin Bio-Oil to Hydrocarbons.

Electrocatalytic hydrodeoxygenation (EHDO) is a promising approach for upgrading biomass-derived bio-oils to sustainable fuels without the use of high-pressure hydrogen gas and elevated temperatures. However, direct EHDO for realistic hydrophobic lignin-based oil production remains challenging. Herein, we discuss the molecular dynamics that govern the EHDO of lignin bio-oil over Pt/C in an acidic electrolyte added with 2-propanol or a surfactant.

Genetic variations underlying aminoglycoside resistance in antibiotic-induced Mycobacterium intracellulare mutants.

Mycobacterium avium complex (MAC) is an emerging pathogen leading to public health concerns in developing and developed countries, particularly among immunocompromised individuals and patients with structural lung diseases. Current clinical guidelines recommend combination antibiotic therapy for treating MAC pulmonary disease (MAC-PD). However, the rising prevalence of antibiotic resistance poses significant challenges, including treatment failure and clinical recurrence.

Ultrasound-guided peripheral intravenous access in adults: A randomized crossover controlled trial.

Background: Peripheral intravenous access is a common invasive clinical procedure, and difficult peripheral intravenous access is a common problem in the care of emergency and critically ill patients. The timeliness of immediate treatment is affected by the difficulty of intravenous access in clinical practice, which endangers patient safety. Repeated injections increase the pressure on nursing staff, consume more nursing hours, and incur higher medical costs.
