Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

Synergistic Effects of Co‐Activation Agents on an MnO–Activated Carbon Composite Electrode for Electrochemical Supercapacitors

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon materials synthesized from biomass are promising candidates for supercapacitor electrodes. Various activation processes for developing carbon materials with high surface areas have been investigated. Here, a manganese monoxide (MnO)–porous‐activated carbon (AC) composite was fabricated via the chemical activation of coconut shell by the

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Parental Stress and Caregiver Role Modulate Child–Caregiver Prosodic Synchrony in Autism: A Computational Analysis

open access: yesAutism Research, EarlyView.
ABSTRACT Parental stress influences parent–child interactions in typical development and is a prognostic factor of autism outcome. However, we still do not know to what extent parental stress affects parent–child interactions and whether caregiver role matters.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

A Structural Safety Analysis of Buildings During Construction [PDF]

open access: yes, 1981
The safety of steel buildings, constructed by the tier method, is evaluated. The probability of failure of steel frames supported on temporary connections is examined during the different stages of completion.
