Summary: Semantic segmentation of Martian terrain is crucial for rover route planning and navigation on Mars. Existing methods perform poorly in the unstructured Martian environment. Therefore, a novel hybrid attention semantic segmentation (HASS) network is proposed, which includes a global intra-class attention branch, a local inter-class attention branch, and a representation merging module. In addition, a panorama semantic segmentation dataset named MarsScapes is established, providing fine-grained annotations for eight semantic categories. Extensive experiments on MarsScapes and the public AI4Mars datasets demonstrate the superiority of the proposed method.

Summary: Dyes, antibiotics, heavy metal ions, and bacteria are significant sources of water pollution. Photocatalytic technology, as a simple and environmentally friendly treatment method, has been widely studied in order to solve these pollution issues. However, conventional powder photocatalysts cause secondary pollution and are not easy to recycle. Therefore, electrospinning technology has been favored for building large specific surface area and reusable membrane photocatalysts.

Summary: This study utilized three types of electrohydrodynamic atomization processes (electrospraying, electrospinning, and coaxial electrospinning) to create ultra-thin products based on hydroxypropyl methylcellulose (HPMC) for the fast dissolution of a poorly water-soluble drug, ketoprofen (KET). The results showed that the electrospun nanofibers, electrosprayed microparticles, and core-shell nanofibers had the expected morphology and inner structure, with KET mainly in an amorphous state. In vitro dissolution tests demonstrated that the core-shell nanofibers (E3) had the best rapid release performance. EHDA nanostructures can support the development of nano drug delivery systems by tailoring the spatial distribution of drug molecules within the nano products.
