Article Abstract
The contemporary mobile communication has undergone a significant shift toward a novel phase characterized by the emergence of beyond 5G (B5G) and 6G technologies. These advancements underscore a focus on enhanced spectral efficiency, minimized latency, and expansive connectivity. This paper thoroughly examines 6G wireless communication networks, including their architectural framework, key technologies, application scenarios, use cases, and challenges. The architectural blueprint of 6G networks integrates space, terrestrial, aerial, and undersea communications to facilitate deep connectivity across various scenarios, which is to meet the increasing future communication requisites. Toward this end, the paper proposes 15 key technologies such as terahertz communication, visible light communication, dynamic spectrum sharing, ultra-massive multiple-input multiple-output (MIMO), and in-band full-duplex. Furthermore, typical scenarios and emerging use cases of 6G are detailed. Conclusively, this paper expounds upon potential challenges in developing and suggests the corresponding solutions, fostering a global dialogue on this transformative technological frontier.

Understanding hydrogen bonding and ion-specific interactions in water, sodium sulfate (NaSO), and acetonitrile (ACN) systems remains challenging due to their complex, dynamic nature. Here, Raman spectroscopy is employed to probe hydrogen bonding networks and ion reorganization in NaSO aqueous solutions with different ACN concentrations. The results indicate that, at low ACN concentrations in the ternary solutions, hydrogen bonding between ACN and water molecules disrupts the original hydration structure of the ions, resulting in the formation of small ion clusters via electrostatic interactions.

With the persistence of difficult employment, a large number of college students feel anxious and nervous about job hunting. College students with different family economic status have various feelings and performances when faced with employment, possibly due to subjective social class differences. The present study investigated the employment confidence of 611 undergraduates in Chongqing, aimed to ascertain the overall employment confidence of Chinese college students, and tried to analyze how subjective social class works on the employment confidence of college students and its influencing mechanism.

Background: A modified pull-through approach represents a promising treatment strategy to access tumors in the posterior oral cavity. The design of the wedge osteotomy plays a key role in preserving postoperative mechanical stability while enabling surgical access. However, the optimal osteotomy design to reduce fracture risk remains unclear.

Background: Little is documented on key community-based One Health (OH) approach implementation, pro-activeness and effectiveness of interactions and strategies against Mpox outbreak public health emergency in international concern (PHEIC) in various African countries in order to stamp out the persisting Mpox outbreak threat and burden. Prioritizing critical community-based interventions and lessons learned from previous COVID-19, Mpox, Ebola, COVID-19, Rift Valley Fever and Marburg virus outbreaks revealed critical shortcomings in funding, surveillance, and community engagement that plague public health initiatives across the continent. The article provides critical insights and benefits of community-based One Health approaches implementation against Mpox outbreak management in Africa.
