Jointless Tongue‐Like Bioactuator for Multidirectional Motion Through Directional Electrical Stimulation

Advanced Intelligent Systems, EarlyView.
A tongue‐like bioactuator is developed using orthogonally aligned cultured skeletal muscle tissues. By applying directional electrical stimulation of varying strengths, the actuator achieves jointless, multidirectional movements. The device features a fully soft, skeleton‐free design, enabling biomimetic deformation and functional actuation, and offers

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.

A Fault Diagnosis Method for Typical Failures of Marine Diesel Engines Based on Multisource Information Fusion

Shock and Vibration
Due to the fact that different components of a diesel engine may exhibit the same fault phenomenon, leading to a low fault identification rate caused by one effect with multiple causes, this paper acquires multiple thermodynamic parameters under various ...

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.

Fusion Artmap: A Neural Network Architecture for Multi-Channel Data Fusion and Classification [PDF]

, 1993
Fusion ARTMAP is a self-organizing neural network architecture for multi-channel, or multi-sensor, data fusion. Single-channel Fusion ARTMAP is functionally equivalent to Fuzzy ART during unsupervised learning and to Fuzzy ARTMAP during supervised ...

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.
