Unmanned aerial vehicle (UAV) can work as mobile edge computing (MEC) server in the sky to provide communication and computation services ground terminals (GTs), due its high mobility. However, UAV might complicated environment, where UAV-GT links being frequently blocked by obstacles, then leading a poor quality of service (QoS) on task latency. To this problem, reconfigurable intelligent surface (RIS) assist improve wireless environment reflecting transmitted signals between GTs....
<p>The increasing prominence of data centers (DCs) in the global digital economy has raised concerns about energy consumption and carbon emissions. Simultaneously, rapid advancement integrated systems (IES) enabled DCs to efficiently harness clean waste heat, contributing sustainability. A concept center system (DC-IES) is introduced this paper, its generalization, approaches, methods, techniques, future perspectives are scrutinized on utilization renewable energy, recovery...
Mega-constellation Low Earth Orbit (LEO) Satellite Networks (LSNs) have become an ongoing projection to realize the ubiquitous large-capacity wireless communication. With rapid growth of satellite scale, transmission efficiency LSNs is substantially decreased as Average Shortest Path Length (ASPL) dramatically increased, which not only encumbers high-speed data transmission, but results in more processing delay, cost energy, rerouting probability and loss rate packets. To this end, paper...
With the urbanization construction and advancement of carbon peaking neutrality goals, urban energy systems are characterized by coupling multi-energy networks a high proportion renewable energy.

In the Internet of Things (IoT), massive sensitive and confidential information is transmitted wirelessly, making security a serious concern. This particularly true when technologies, such as nonorthogonal multiple access (NOMA), are used, it possible for users to each other's data. article studies secure communications in multiuser NOMA downlink systems, where user potentially an eavesdropper. Resource allocation formulated achieve maximum sum secrecy rate, meanwhile satisfying users' data...
The potassium (K) metal anode, following the "Holy Grail" Li is one of most promising anode materials for next-generation batteries. In comparison with Li, K exhibits even more pronounced energy storage properties. However, it suffers from similar challenges as alkali anodes, such safety and cyclability issues. Borrowing strategies Li/Na three-dimensional (3D)-structured current collector has proven to be a universal effective strategy. This study examines recent research progress...
We consider opportunistic scheduling in a downlink OFDMA system to support heterogeneous services. Given the user's queue state information (QSI) and channel (CSI), proposed sum waiting time based (SWBS) algorithm can guarantee QoS requirements for both real-time (RT) non-real-time (NRT) service.

Experimental results point out that film is a polar material, i.e. there exists both oriented dipoles deposited space charge in after charging. Estimating polarizations at different charging fields based on analysis current curves indicate comparatively high polarization formed under field above...
Experimental and theoretical results are presented on the lifetime of organic light emitting diodes (OLEDs) for active matrix display applications. DC aging tests OLEDs show that driving voltage increases under forward bias then reverse its trend when polarity is reversed, which reproduce our previous test AC conditions.
