Remote sensing object counting remains challenging for lightweight models due to large scale variation, dense object distribution, and complex background interference. Existing lightweight counting methods usually rely on static multi-scale fusion, which limits adaptive receptive-field selection under heterogen...

This article presents a low-profile dual-polarized phased array antenna featuring an improved feed structure and a multiresonant wide-angle impedance matching (WAIM) layer for satellite-assisted Internet-of-Things (SATA-IoT) vehicular communications across the L-, S-, C-, and X-bands. First, an improved fe...

An ultrawideband magnetoelectric (ME) dipole antenna with stable gain is proposed for sub-6G Internet of Things (IoT) communication systems. While several structures can effectively achieve a wide impedance bandwidth, a critical limitation is that an excessively wide beamwidth often results in&#x...

A quadrature-spoof surface plasmon polariton (SSPP) unit cell (QS-UC) is proposed and theoretically characterized for circularly polarized (CP) wave generation. The proposed QS-UC is composed of a fishbone SSPP waveguide (FSW) and a spine quadrature mode converter (SQMC), which converts the ...

This paper presents a new set of linear polarization to circular polarization (LP-CP) unit cells (UCs) for broadband reflective polarization conversion, and the application in designing broadband CP reflectarray (RA). The LP-CP UCs are composed of different combinations of rectangular loops ...

To enhance the effectiveness of fracture process simulation within the Rock Fracture Process Analysis (RFPA) framework, this study proposes a cohesive-enhanced RFPA (CRFPA) method. Cohesive elements are pre-inserted along potential fracture interfaces, either globally or locally, providing modeling flexibi...

The rapid growth in lithium-ion battery (LIB) deployment has led to increasing volumes of end-of-life batteries, creating an urgent need for sustainable recycling technologies capable of recovering critical metals from complex waste streams. Although leaching has been successfully shown in variou...

Zinc-Manganese dioxide (MnO₂) batteries have garnered significant interest due to their high energy density, low cost and low toxicity. Crystalline MnO₂ has shown structural transformations during the intercalation and deintercalation of Zn, which influences the performance of the battery. Recent ...

In the context of global energy transition and net-zero emission goals, supercritical carbon dioxide (sCO₂) technology has emerged as a core solution for next-generation low-carbon energy conversion systems. However, the combustion characteristics of fuel/oxidizer in sCO₂ environments remain underexpl...
