Wide-field surveys have markedly enhanced the discovery and study of solar system objects (SSOs). The 2.5-meter Wide Field Survey Telescope (WFST) represents foremost facility dedicated to optical time-domain in northern hemisphere. To fully exploit WFST's capabilities for SSO detection, we developed a heliocentric-orbiting processing (HOPS) tailored identifying these objects. This integrates HelioLinC3D, an algorithm well suited WFST survey cadence, characterized by revisiting same sky...
This paper delves into the intricacies of temperature control and crack prevention in construction large volume concrete structures, emphasizing their criticality for maintaining structural integrity longevity. The primary challenges arise from exothermic hydration cement, leading to substantial internal variations consequent thermal stresses. To address these, explores a comprehensive approach starting with selection raw materials mix design. It advocates use low-heat supplementary...
Abstract Nanozymes based on metals have been regarded as a promising candidate in the metabolic reprogramming of low-survival, refractory glioblastoma multiforme (GBM). However, due to size limitations, nanozymes struggle balance catalytic activity with ability cross blood-brain barrier (BBB), limiting their efficiency GBM therapy. Herein, we establish hybrid clustered nanozyme (AM NCs) by cross-linking ultrasmall nano-gold (Au) and manganese oxide (MnO2), which overcomes requirement...
Clinicians frequently face difficulties when trying to fix bone abnormalities. Gelatin-Alginate (GA) is employed as a carrier because it non-toxic, biodegradable, and has three-dimensional network structure. Meanwhile, cerium oxide nanoparticles (nCeO2) demonstrated high antioxidant enzyme simulation activity. Therefore, in order develop porous hydrogel scaffold for the application of tissue engineering, an appropriate-type GA-nCeO2 was developed evaluated. prepared by lyophilized method...
The efforts provide a prospective fate of the zirconium powder with high ESD sensitivity and water-containing electrically controlled rocket fuels possessing poor compatibility typical high-activity micro-nano metal fuels.
Robot path planning is an important component of ensuring the robots complete work tasks effectively. Nowadays, most maps used for robot obtain relevant coordinate information through sensor measurement, establish a map model based on information, and then carry out robot, which time-consuming labor-intensive. To solve this problem, method ant colony algorithms after standardized design non-standard grids such as photos was studied. This combines grid modeling with image processing, bringing...
This paper presents a discrete-time model to describe the movements of group trains, in which some operational strategies, including traction operation, braking operation and impact stochastic disturbance, are defined. To show dynamic characteristics train traffic flow with numerical experiments on railway line simulated. The computational results that movement can well trains rail moving-block signalling system. Comparing no it finds capacity will decrease influence disturbance....
The maps used for the path planning of mobile robots are mostly grid maps, which generated through independent design or sensor measurement to obtain relevant information and then modeling. To robot motion more quickly, this paper proposes a method ant colony algorithm under non-standard environment map. map is standard design, optimized by no safety distance added obstacle box selected selected, carried out algorithm. In addition, mutual correspondence between real was solved adding...
The Safe following distance is closely associated with vehicle braking process. process consists of three stages. key problem in this research area to quantitatively describe each stage.
