Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

Advanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones.

Working Memories for Storage and Recall of Arbitrary Temporal Sequences [PDF]

, 1992
A working memory model is described that is capable of storing and recalling arbitrary temporal sequences of events, including repeated items. These memories encode the invariant temporal order of sequential events that may be presented at widely ...

Animal models of chronic thromboembolic pulmonary hypertension

Animal Models and Experimental Medicine, EarlyView.
Current animal models of CTEPH. Created using BioRender.com. Abstract Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, yet life‐threatening disorder characterized by persistent pulmonary vascular obstruction and elevated pulmonary artery pressure, with progressive remodeling and subsequent right heart failure.

Controlling light emission from semiconductor nanoplatelets using surface chemistry

Nature Communications
Semiconductor nanoplatelets are atomically flat nanocrystals which emit light with high spectral purity at wavelengths controlled by their thickness. Despite their technological potential, efforts to further sharpen the emission lines of nanoplatelets ...
