Sensorless Human–Robot Interaction: Real‐Time Estimation of Co‐Grasped Object Mass and Human Wrench for Compliant Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
To tackle the challenge of parameter estimation in dynamic human–robot interaction, this research proposes a novel method that integrates a disturbance observer with Kalman filtering. In contrast to conventional techniques, this approach facilitates the simultaneous real‐time estimation of human wrench and object parameters, offering significantly ...

A Soft Wearable Robot with an Adjustable Twisted String Actuator and a Two‐Stage Transmission Mechanism for Manual Handling Tasks

open access: yesAdvanced Intelligent Systems, EarlyView.
This article proposes a soft wearable robot (WeaRo) to assist workers while executing manual handling tasks. With its innovative design, the WeaRo effectively assists multiple body parts during manual handling tasks while using a single motor. Furthermore, the components of the WeaRo are assembled onto a fabric‐based suit, ensuring high performance and

Self‐Rhythmic Soft Pneumatic Pressure Regulation System Based on Self‐Excited Oscillation of Jet Hose

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a soft pneumatic pressure regulation system that uses self‐excited hose oscillations to convert constant pressure (90–150 kPa) into rhythmic output. Simulations and experiments demonstrate tunable oscillation frequencies (5.9–11.1 Hz) through adjustments in pressure, hose length, and jet hole diameter.

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.

Yunweiling alleviates functional constipation: integrating network pharmacology and experimental study

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In a study combining network pharmacological analysis and experimental verification, yunweiling has been shown improve functional constipation by inhibiting the PI3K‐Akt‐p53 signaling pathway and reducing the expression of TP53. Abstract Background This study investigated the impacts and mechanisms of yunweiling in the management of Functional ...

Comparative pathogenicity of vaccinia virus and mpox virus infections in CAST/EiJ mice: Exploring splenomegaly and transcriptomic profiles

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We successfully constructed CAST/EiJ mice models infected with low‐dose vaccinia virus (VACV‐L), high‐dose VACV (VACV‐H), and mpox virus (MPXV), demonstrating that VACV‐L and MPXV infections induced splenomegaly in mice, and VACV‐H infection caused mortality in mice.

Comparison of the pathogenicity of multiple SARS‐CoV‐2 variants in mouse models

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We assessed the pathogenicity of various SARS‐CoV‐2 variants using two distinct mouse models. Our findings indicated that earlier variants, including WH‐09, Beta, and Delta, exhibited greater pathogenicity than later variants. Specifically, the Omicron variant demonstrated reduced pathogenicity, characterized by a shorter disease course and diminished ...
