The sixth generation (6G) is conceived to address the expected high level of requirements (such as ultra-high-data-transmission rate, support for the highest moving speed and seamless connection, etc.) in the next decade and beyond. In the context of 6G, a large number of Industrial Internet of Things (IoT) (IIoT) devices may access the network, and thanks to the rapid development of artificial intelligence make smart manufacturing has the opportunity to be realized. However, a large number of I

In the context of the 5G/6G mobile network, high levels of requirements such as ultra-high data transmission rate, support for the high mobility node and seamless connection need to be handled. Additionally, ensuring user quality of service (QoS) in high-density and high-traffic mobile networks presents a significant challenge. Unmanned aerial vehicles (UAVs) have emerged as key components in providing flexible assistance in aerial spaces. To further enhance the network performance in dynamic an

With the expected explosive growth of the number of mobile user devices and data traffic in the next decade and beyond, and the expected development of various new applications and services such as vehicle-to-everything, extended reality and smart city, the requirements for Quality of Service (such as ultra-high data transmission rate, ultra-low latency, support for the highest moving speed and seamless connection, etc.) will reach levels never seen before. The sixth generation (6G) of networks

The current 5G and conceived 6G era with ultra-high density, ultra-high frequency bandwidth, and ultra-low latency can support emerging applications like Extended Reality (XR), Vehicle to Everything (V2X), and massive Internet of Things (IoT). With the rapid growth of transmission rate requirements and link numbers in the wireless communication network, how to allocate resources reasonably and further improve spectrum utilization challenges the traditional approaches. To address these problems,

Due to the surge in the development of new applications and services requires high-quality user experiences, characterized by high data transmission rates, low latency, and seamless network connectivity, the space-air-ground integrated network (SAGIN) that combines satellite networks, aerial networks, and terrestrial networks, offering ubiquitous global network services to ground users and enhancing connectivity for a wide range of wireless applications, is rising as the promising architecture f

Space-air-ground integrated network (SAGIN) is a promising network architecture for next-generation wireless networks, which combines satellite networks, aerial networks, and terrestrial networks to enable ubiquitous global network services to ground users and improve connectivity for wide deployment wireless applications. Also, free-space optical (FSO) communication with the advantages of low deployment cost, energy efficiency, and extremely high-speed data-delivering capability has attracted m

Space-Air-Ground Integrated Network (SAGIN) is a promising architecture for next-generation wireless networks. It combines satellite networks, aerial networks, and terrestrial networks, offering ubiquitous global network services to ground users and enhancing connectivity for a wide range of wireless communications. Additionally, free-space optical (FSO) communication has gained more attention recently because of its energy efficiency and exceptional high-speed data delivery capabilities. Howeve

Objective To compare the neonatal outcomes of different gestational age at which elective cesarean sections at term were performed. Methods All the cases of cesarean section registered in Peking Union Medical College Hospital from September 2002 to November 2009 were collected. Women with viable singleton pregnancies delivered before the onset of labor and without recognized indications for cesarean section after 37 weeks at term were included and their general information and outcomes were comp

Condition being studied: Relationship between perceived teacher support and student engagement in physical education.

In view of various security requirements, there are various security services in the network. In particular, DDoS attacks have various types and detection methods. How to flexibly combine security services and make full use of the information provided by security services have become urgent problems to be solved. This paper combines the reasoning ability of the malicious behavior knowledge base to realize the dynamic deployment of the service function chain and dynamic configuration of the secur

SaaS is widely used in the fields of operation management, business process outsourcing, data analysis, and information security. However, with the improvement of the degree of information, the generalized SaaS platform is unable to satisfy the requirements of enterprise personalization. SaaS products face great challenges in personalized customization technology due to the application of multi-tenant architecture. The challenges include multi-tenant customization in SaaS model, data isolation d

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in males, which is characterized by persistent discomfort or pain in the pelvic region. As currently used drug therapies fail to produce satisfactory results, it is an urgent task to find new and effective methods for the treatment of CP/CPPS. In recent years, many reports are seen on the extracorporeal shock wave therapy (ESWT) for CP/CPPS. ESWT can significantly improve the symptoms of pelvic pain and urination diso

Individuals' consumption behavior varies as systems change. In the period of planned economy, there was no variety in people's consumption structure, their consumption tendency was high while their consumption level was low. When China entered into its period of Bisystems, there was an increase in choices available to individual consumers, an increasing recognition of consumer goods provided by the and an increase in advance consumptions. In the present context of buyer's market, people's consu
