Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

Advanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

A Soft Robotic Jellyfish with Decoupled Actuators for Agile 3D Locomotion

Advanced Intelligent Systems, EarlyView.
This study presents a soft robotic jellyfish featuring a functionally decoupled actuation architecture. By separating propulsion, steering, and vertical regulation into independent modules, the robot overcomes conventional coupled‐motion limitations. Utilizing a passive‐valve‐based differential drag strategy and lateral water jets, it achieves agile 3D

Algodoo for online education: impulse and momentum activities

Physics Education, 2021
Abstract During the periods of sudden transition to online education, the opportunity to make applications that might attract students’ attention to the course has decreased even more. Although this deficiency tried to be eliminated with videos and simulations, it was not possible to ensure the active participation of students in some

Dynamics of one-dimensional tight-binding models with arbitrary time-dependent external homogeneous fields

, 2012
The exact propagators of two one-dimensional systems with time-dependent external fields are presented by following the path-integral method. It is shown that the Bloch acceleration theorem can be generalized to the impulse-momentum theorem in quantum ...

Gate‐Align‐SED: Semi‐Supervised Sound Event Detection via Adaptive Feature Gating and Cross‐Task Alignment in Situation Awareness

Advanced Intelligent Systems, EarlyView.
Overview of the proposed Gate‐Align‐SED, including two stages of training: (1) Mean‐Teacher SSL Training; and (2) Enhancer Model Training. In complex real‐world environments such as disaster monitoring, effective sound event detection (SED) is often hindered by the presence of noise and limited labeled data.

Chiral Perturbation Theory and the pp -> pp pi0 Reaction Near Threshold

, 1997
A chiral-perturbative consideration of the near-threshold pp -> pp pi0 reaction indicates that the pion-rescattering term has a substantial energy and momentum dependence.

Implementing Indigenous Data Sovereignty in Australia: A Five‐Phase Framework for Indigenous Data Governance

Australian Journal of Social Issues, EarlyView.
ABSTRACT This article presents the development of a five‐phase Indigenous Data Governance (IDGov) Framework in Australia, focusing on partnerships between the Aboriginal Community Controlled Health Organisation (ACCHO) sector and non‐Indigenous health entities.

Experimental evidence of shock mitigation in a Hertzian tapered chain

, 2006
We present an experimental study of the mechanical impulse propagation through a horizontal alignment of elastic spheres of progressively decreasing diameter $\phi_n$, namely a tapered chain.

Strengthening Treaty Understanding: The Role of Education in Building Durable Indigenous–State Agreements

Australian Journal of Social Issues, EarlyView.
ABSTRACT Education is a central mechanism for ensuring that Indigenous–State treaties are understood, supported and endure through political change. Public knowledge shapes the negotiation, acceptance, implementation and long‐term stability of agreements. In Australia, however, treaty knowledge remains fragmented.
