Photo-/Electrothermally Gated Slippery-Pore Surface for All-Weather Anti-/De-icing and Meltwater Drainage

Icing threatens the safe operation of aircraft, power facilities, wind turbine blades, and other engineering surfaces. Although existing superhydrophobic, photothermal, electrothermal, and drainage surfaces can individually delay freezing, actively melt ice, or transport liquids,...

Evaluating net energy value of fermented citrus pulp and its effects on performance and egg quality in laying hens

Two experiments were conducted to determine the apparent metabolisable energy (AME), nitrogen-corrected apparent metabolisable energy (AMEn), and net energy (NE) values of fermented citrus pulp (FCP) for layers and to evaluate its effects on performance and egg quality. In Experi...

An AHP-fuzzy FMEA and bow-tie barrier approach for maintenance risk assessment of outdoor-parked general aviation aircraft

Purpose This study aims to evaluate a maintenance risk-prioritization and barrier-mapping workflow for outdoor-parked general aviation aircraft. Design/methodology/approach Six failure scenarios were identified from 220 anonymized records covering 23 long-parking episodes and ass...

Analysis of the Characteristics of a Microburst Event at Urumqi Airport Based on Microwave Radiometer and Doppler Wind Lidar

Microbursts can cause severe low-level wind shear, posing a threat to aviation safety. However, due to their small scale, they are difficult to capture by conventional equipment such as surface Automated Weather Observing Systems (AWOS) and Doppler weather radar. On 25 June 2022,...

Strategic flight planning and conflict management for urban air mobility operations: a mission preference-constrained multiagent reinforcement learning approach

As an emerging low-altitude transportation paradigm, urban air mobility (UAM) is envisioned to support high-density and demand-driven operations involving diverse and flexible mission requests. However, the imbalance between limited urban airspace resources and growing operationa...

Teachers' AI use and student learning outcomes in higher education: The roles of learning engagement and teacher AI literacy

Bio-inspired functional recursion enables multi-mode locomotion in a 140-mg morphing microrobot

Insects traverse diverse environments by reusing body structures and appendages through adaptable mechanics, an ability that remains a grand challenge for insect-scale robotics under strict mass constraints. Here we present an insect‑scale robot that integrates aerial takeoff and...

Cranial anthropometry and physical conditioning in relation to handstand endurance and fixed-roller task performance in male flight cadets

To explore associations of cranial anthropometric and physical-conditioning measures with handstand endurance and 30-second fixed-roller task performance in male flight cadets. In this cross-sectional study, 77 male Han Chinese flight cadets aged 18–19 years underwent assessment...

Interface Engineering via Ceria Coating Reconciles Ion Transport and Lithium Compatibility in Composite Polymer Electrolytes

ABSTRACT Composite polymer electrolytes (CPEs) exhibit considerable potential for solid−state lithium−metal batteries (SLBs). However, incompatibilities between the various components in the electrolyte continue to hinder the full realization of its performance and practical appl...

Microstructure and Texture Evolution of GWS841 Magnesium Alloy During Hot Extrusion

In this experiment, the solid solution GWS841 magnesium alloy was deformed by hot extrusion at 500 °C. EBSD was used to analyze the evolution of microstructure and texture under different degrees of deformation. The results showed that the average grain size decreased from 75.8 μ...

DCRT: Depth-confidence-guided complementary residual temporal adapter for camera-based BEV 3D object detection

Abstract Camera-based bird's-eye-view (BEV) 3D object detection is important for autonomous-driving perception, but the quality of BEV representations is easily affected by depth-estimation errors, object motion, and cross-frame alignment errors. Existing temporal BEV detection m...
