Smart Health Evaluation for Lithium‐Ion Battery With Super‐Short‐Segment Charging

open access: yesAdvanced Science, EarlyView.
This study proposes a health feature extraction method integrating degradation mechanism‐guided scale‐invariant feature transform with machine learning for lithium‐ion batteries. Validated across 87 commercial cells with diverse chemistries and formats, it achieves 1.97% RMSE in capacity estimation using only 10% charging segments. The approach enables

Fatigue Limit Doubling in High‐Strength Martensitic Steel through Crack Embryo Engineering–Cyclic‐Training‐Driven Self‐Optimization

open access: yesAdvanced Science, EarlyView.
This study demonstrates a breakthrough in overcoming the conventional fatigue limit ceiling in high‐strength as‐quenched martensitic steel; maximum stress corresponding to the fatigue limit significantly increased from 675 to 1300 MPa with minimal sacrifice in tensile strength (1.5–1.6 GPa).

A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication

open access: yesAdvanced Science, EarlyView.
A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.

Dedifferentiation and Transfer in Executive Function and Math Ability Following a Five‐Year Abacus Training in Schoolchildren

open access: yesAdvanced Science, EarlyView.
While cognitive development typically exhibits differentiation, marked by decreasing inter‐domain correlations, this study demonstrates that five‐year abacus training is associated with de‐differentiation of executive function and mathematical ability in school‐aged children.
