Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility
Advanced Intelligent Systems, EarlyView.This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Study of low-noise face gear drives associated with micro-punch webs
Advances in Mechanical Engineering, 2016 Face gear dynamics is addressed by many scholars. However, design solutions of low-noise face gear drives without gear tooth modifications are not to be constructed.

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups
American Journal of Community Psychology, EarlyView.Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Australia's Migration Strategy: An Effective Response to Migrant Worker Exploitation?
Australian Journal of Social Issues, EarlyView.ABSTRACT A series of publicised migrant worker injuries and deaths has drawn attention to the issue of migrant worker exploitation (MWE) in Australia. In response, the Australian Government has included ‘Tackling Worker Exploitation’ as a key area of its Migration Strategy which it introduced in 2023. However, it is unclear how effective the Strategy’s

Journal of Applied Polymer Science, EarlyView.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...
