Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

Observation of non Diffusive Term of Toroidal Momentum Transport in the JFT-2M Tokamak [PDF]

, 1993
Toroidal rotation velocity profiles are measured with multi-chord charge-exchange spectroscopy for the discharge that the neutral beams are interchanged from parallel (co) to anti-parallel (counter) to the direction of the plasma current.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Design of a new parametric method for low-noise toroidal propeller and its hydrodynamic noise study

Zhongguo Jianchuan Yanjiu
ObjectiveThe vortex generated by the toroidal propeller's rotation is distributed across the entire blade, effectively preventing tip vortex leakage and allowing the vortex to dissipate rapidly in water, thereby reducing the propagation of hydrodynamic ...

Evidence for Toroidal B-Field Components in AGN Jets on Kiloparsec Scales

Galaxies, 2017
Though helical magnetic fields are generally believed to arise when the jets of Active Galactic Nuclei (AGN) are launched, it is still unclear what role they play (and if they survive) to the largest jet scales.

Impacting Fuelling Dynamics Towards Tunable Liquid Metal Machine

Exploration, EarlyView.
Confining liquid metal machines (LMMs) within one‐dimensional semi‐open channels reveals sustained, tuneable reciprocating dynamics, driven by fuel region evolution and boundary interactions. This work elucidates how spatial confinement and obstacle materials regulate symmetry‐breaking and directional control, enabling predictable LMM operation and ...

Programmable solar‐blind ultraviolet sensors enabling integrated single‐pixel sensing and neuromorphic processing

InfoMat, EarlyView.
A Schottky photodiode based on (Al0.14Ga0.86)2O3 was developed, in which the sensing and processing functions were temporally decoupled through bias voltage modulation. By integrating single‐pixel imaging with a reservoir computing architecture, a comprehensive intelligent vision system was constructed.

Transport-driven toroidal rotation with general viscosity profile

Nuclear Fusion
Using the assumption of a weak normalized turbulent viscosity, usually valid in practice, the modulated-transport model (Stoltzfus-Dueck 2012 Phys. Plasmas 19 055908) is generalized to allow the turbulent transport coefficient to vary in an arbitrary way
