A heterogeneous micro aerial vehicles (MAV) swarm consists of resource-intensive but expensive advanced MAVs (AMAVs) and resource-limited cost-effective basic (BMAVs), offering opportunities in diverse fields.Accurate real-time localization is crucial for MAV swarms, current practices lack a low-cost, high-precision, solution, especially lightweight BMAVs.We find an opportunity to accomplish the task by transforming AMAVs into mobile infrastructures BMAVs.However, turning this insight...

Multi-UAV systems have shown immense potential in handling complex tasks large-scale, dynamic, and cold-start (i.e., limited prior knowledge) scenarios, such as wildfire suppression. Due to the dynamic stochastic environmental conditions, scheduling for sensing fire monitoring) operation suppression) should be executed concurrently enable real-time information collection timely intervention of environment. However, planning inclinations are typically inconsistent evolve over time,...

Emergency rescue scenarios are considered to be high-risk scenarios. Using a micro air vehicle (MAV) swarm explore the environment can provide valuable environmental information. However, due absence of localization infrastructure and limited on-board capabilities, it's challenging for low-cost MAV maintain precise localization. In this paper, collaborative system heterogeneous is proposed. This takes full advantage advanced effectively achieve accurate through collaboration. Subsequently,...

The Bohai Bay Basin is a Meso-Cenozoic rifted basin where the Paleozoic buried hills with great hydrocarbon potentials are well developed. reservoir space types complex and diverse due to tectonic activities, making fracture distribution highly heterogeneous. Reservoir identification mapping challenging their large burial depth poor resolution of seismic data. An integration well-logging, data interpretation core observation applied identify three structural unit in study area, that is,...

High-performance photodetectors are crucial to developing cutting-edge technologies in many disciplines, such as medicine, optical communication, display and imaging, military, environmental monitoring, security checks, scientific research, industrial process control. Field-effect phototransistors (FETs) using an amorphous oxide semiconductor, zinc–tin (ZTO), show great potential next-generation photodetectors. Regrettably, typical ZTO-based FETs have drawbacks preventing their widespread...

Structural models in economics can offer appealing insights but often suffer from a poor fit with the data. In contrast, machine learning rich flexibility tend to over-fitting. We propose novel framework that incorporates useful economic restrictions structural model into through transfer learning. The core idea is first construct neural-network representation of model, and then update network using information real an example application option pricing, our hybrid significantly outperforms...

Rationale Rivaroxaban is a new anticoagulant drug that has recently been introduced for clinical applications. To ensure optimum efficacy while minimizing the risk of toxicity and other adverse effects, simple sensitive analytical procedure monitoring concentration rivaroxaban in biological fluids required. Methods was extracted from aqueous solutions by dispersive liquid‐liquid microextraction (DLLME). Detection achieved through surface‐assisted laser desorption/ionization mass spectrometry...

Liver cancer or hepatic is a that originates in the liver. It formed from either liver itself structures within liver, including blood vessels bile duct. can be life-threatening condition, but it may cured if found early. Hepatic artery embolization one of treatment options involving injection substances to reduce flow cells livers patients with tumors cannot removed by surgery; however, this has some limitations. In paper, we propose novel nitinol “spherical occlusion device” concept, first...

An attractive strategy for quantitative analysis of the grain mixtures black sesame paste was proposed in this research by combined application FT-IR spectroscopy and chemometrics. The spectra three (black sesame, rice, bean) mixtures, which are used producing were collected. Based on spectra, different regression methods utilized optimized to estimate each mixture component content. PCA-Class results revealed that class highly distinct allowed discrimination from others. PLSR, siPLS, PCR...

In this paper, we present a series of different thermotropic discotic columnar liquid crystalline forms mono-substituted functionalised hexabenzocoronene (HBC) carrying five alkyl chains. Using the Sonogashira coupling reaction, 1-ethynyl-4-alkylbenzene, 1-ethynyl-4-alkoxybenzene, and alkyl-4-ethynyl benzoate groups were introduced into mono-bromohexabenzocoronenes to obtain compounds 5–7. These obtained characterised by 1H 13C-NMR, UV-Vis, MALDI-MS spectrometry. The (LC) properties...

Rupture-prone plaques in the coronary arteries, called ``vulnerable plaques'', are recognized as key factor acute myocardial infarction. Vulnerable have a thin fibrous cap over large fatty core and highly susceptible to rupture. In general, this type of plaque rupture is mainly associated with stress concentrated on cap. Fibrous stresses counted among most important factors process must be taken into consideration when assessing vulnerability leading heart attacks. The objective paper was...

This paper presents a multi-robot distributed cooperative localization method based on the fusion of sound and dead reckoning. First, each robot computes its position orientation by In order to correct accumulative error reckoning, we periodically fuse dead-reckoning results with relative using extended Kalman filter (EKF) algorithm. Two self-made small mobile robots are adopted carry out indoor experiments, unknown is equipped cheap transmitting device known receiving device. By comparing...
