Multirobot Aerial Soft Manipulator for Floating Litter Collection

Advanced Intelligent Systems, EarlyView.
A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies

Reinforcement Learning With a Low‐Cost Parallel Linkage Gripper for Static and Dynamic Planar In‐Hand Manipulation

Advanced Intelligent Systems, EarlyView.
Hardware‐learning co‐design combines volar‐plate‐inspired passive‐joint constraints with mechanism‐aware reinforcement learning for a low‐cost parallel‐linkage gripper. The resulting system performs quasi‐static object adjustment and dynamic pinch grasping, demonstrating reliable planar in‐hand manipulation and successful sim‐to‐real transfer. Parallel

Observation of Latitudinal Asymmetric Ionospheric Disturbances Induced by Typhoon YAGI (2024) Using the BeiDou GEO Satellite

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Typhoons, as intense atmospheric disturbances, are capable of significantly influencing ionospheric conditions, primarily through the excitation of gravity waves, which transfer energy into the ionosphere.

Is Gravity an Entropic Force? [PDF]

, 2011
The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force.

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

The GOCE observations for detecting the full extent of the crust to mantle section brought to the surface in the Kohistan Arc, Himalaya

, 2012
The aim of this work is to use the GOCE observations in a geologically unique part of the Himalayan orogen, which is the Kohistan arc. Here the entire section of the crust from the mantle-crust transition, to the volcanic deposits in the upper crust are ...

Renormalization group flow of f(R)-gravity [PDF]

, 2008
We use the functional renormalization group equation for quantum gravity to construct a non-perturbative flow equation for modified gravity theories of the form $S = \int d^dx \sqrt{g} f(R)$.

MHD Maxwell Hybrid Nanofluid Transport Featuring Solar Radiation and Thermo‐Diffusive Impacts Over a Permeable Slanted Stretching Sheet

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids have emerged as next‐generation working fluids for advanced engineering application due to their superior heat transport capability in relation to the conventional nanofluids. Motivated by the rising demand for accurate prediction of transport phenomena under realistic operating situations, the present study examines the ...

Determination of the gravity disturbance on the earth's topographic surface from airborne gravity gradient data [PDF]

, 1988
The test flight of the gravity gradiometer survey system was taken in a flat area. In the future the tests will be carried out in rough mountain area and the topographic effect has to be taken into account.
