How Does Patient Capital Enhance Agribusiness Resilience? Evidence From Chinese Listed Agribusinesses

open access: yesAgribusiness, EarlyView.
ABSTRACT In emerging economies where smallholder farming dominates agricultural production, agribusinesses serve as critical intermediaries linking smallholders to broader markets, and their resilience directly affects agricultural sustainability. Short‐term‐oriented capital is reluctant to adequately finance highly uncertain and cyclical agricultural ...

Asymptotic Behavior and Uniqueness Results for Boundary Blow-up Solutions

open access: yes, 2009
We estimate the blow-up rate and then improve some existing uniqueness results for boundary blow-up solutions to certain quasilinear elliptic equations with a weight function. The weight function is allowed to vanish on the part of the boundary where the

Bubbles Acting as Micro End‐Effectors for Dexterous Manipulation and Sensing in Aqueous Environment

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Inspired by bubbles, this article proposes a low‐cost method for multifunctional manipulation and sensing using microbubbles in aqueous environments. Bubbles are easily generated in situ, enabling the safe and adaptive handling of microobjects and sensing of microforces and surface textures.

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

open access: yesAdvanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Asymmetric Whisker‐Inspired Sensor Pairs for Enhanced Airflow Sensing on Drones

open access: yesAdvanced Intelligent Systems, EarlyView.
This work incorporates asymmetric cross‐sections into a whisker‐inspired sensor pair to enhance airflow sensing. By comparing signals between two offset asymmetric whiskers, the system improves flow heading estimation and identifies the presence of fan‐generated wind during quadrotor flight.

Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

open access: yesAdvanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

A Multistage Venturi Amplifier for Rapid Inflation of Soft Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents the amplifier inflator for soft robotic systems (AIRS), a compact, lightweight, and effective device for rapidly deploying inflatable structures to high pressure. By integrating a check valve with a Venturi‐based air entrainer, AIRS delivers an initial high‐flow output followed by pressurization, supporting fast inflation and ...

Master narratives as “colonial propaganda” and counternarratives as “refusal”: How African Australians reimagine racial dignity in Australia

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This paper utilizes the concept of “colonial master narratives” to examine how racial propaganda is mobilized in the Australian imaginary to “flatten” the stories of Blac/k people and how African Australians deploy counternarratives to reject these racialized projections.
