AI Article Synopsis

  • Vision-based UAV swarming is emerging as a solution that addresses the issues of adaptability and scalability in traditional UAV communication systems.
  • The study introduces a new finite perception visual (FPV) neighbor selection model, inspired by bird vision, which accounts for visual occlusion and sensor limitations and allows for flexible visual field widths.
  • Through Monte Carlo simulations, the FPV model combined with the Acute Angle Test (AAT) method demonstrates a significant improvement in swarm performance by reducing communication load and enhancing safety and connectivity compared to traditional methods.

Article Abstract

Recently, vision-based unmanned aerial vehicle (UAV) swarming has emerged as a promising alternative that can overcome the adaptability and scalability limitations of distributed and communication-based UAV swarm systems. While most vision-based control algorithms are predicated on the detection of neighboring objects, they often overlook key perceptual factors such as visual occlusion and the impact of visual sensor limitations on swarm performance. To address the interaction problem of neighbor selection at the core of self-organizing UAV swarm control, a perceptually realistic finite perception visual (FPV) neighbor selection model is proposed, which is based on the lateral visual characteristics of birds, incorporates adjustable lateral visual field widths and orientations, and is able to ignore occluded agents. Based on the FPV model, a neighbor selection method based on the acute angle test (AAT) is proposed, which overcomes the limitation that the traditional neighbor selection mechanism can only interact with the nearest neighboring agents. A large number of Monte Carlo simulation comparison experiments show that the proposed FPV+AAT neighbor selection mechanism can reduce the redundant communication burden between large-scale self-organized UAV swarms, and outperforms the traditional neighbor selection method in terms of order, safety, union, connectivity, and noise resistance.

Proximity of maxillary molar palatal roots to adjacent structures for endodontic microsurgery: a cone-beam computed tomography study.

BMC Oral Health

Beijing Yakebot Technology Co., Ltd, F-616-West Building, Yonghe Plaza, No. 28 Andingmen Dongdajie, DongCheng District, Beijing, 100007, China.

Background: The surgical complexity associated with the palatal roots of maxillary molars was considerably elevated. Previous studies on the relationships between maxillary molar roots and the maxillary sinus or cortical plates have focused on individual root observation without considering the positional relationship between buccal and palatal roots or analysing the surgical pathway of maxillary molar palatal roots. This study aimed to investigate the relationship between maxillary molar palatal roots and adjacent anatomical structures to provide a reference for performing palatal roots endodontic microsurgery.

Background: The World Health Organization (WHO) recommends an interval of at least 24 months from the date of a live birth to the conception of the next pregnancy in order to reduce the risk of adverse maternal, perinatal, and infant outcomes. There is limited data about the implementation of this recommendation and its contributing factors in low-land ecologies in Oromia, which is the biggest regional state in Ethiopia.

Objective: To assess the inter-pregnancy interval and determine associated factors among parous women in selected low-land districts of Arsi and East Shoa Zone.

Based on its simple valence electron configuration, we may expect lithium to have straightforward physical properties that are easily explained. However, solid lithium, when cooled below 77 K, develops a complex structure that has been debated for decades. A close parallel is found in sodium below 36 K where the crystal structure still remains unresolved.

ConspectusControlling selectivity through manipulation of reaction intermediates remains one of the most enduring challenges in organic chemistry, providing novel solutions for selective C-C π-bond functionalization. This approach, guided by activation principles, provides an effective method for selective functional group installation, enabling direct synthesis of organic molecules that are inaccessible through conventional pathways. In particular, the selective functionalization of N-conjugated allenes and alkynes has emerged as a promising research focus, driven by advances in controlling reactive intermediates and activation strategies.

Background: The prion model of tau propagation in Alzheimer's Disease predicts that tau seeds are released from cells and taken up by neighboring cells, resulting in spreading of the disease. Our previous work revealed that tau aggregates bind to heparan sulfate proteoglycans (HSPGs) on the cell surface, followed by cellular uptake via macropinocytosis. HSPGs are glycoproteins, consisting of a protein core and decorated with linear glycosaminoglycan (GAG) chains called heparan sulfate (HS) with highly variable sulfation patterns.
