In this paper, we investigate cooperative secure beamforming for simultaneous wireless information and power transfer (SWIPT) in amplify-and-forward (AF) relay networks. We propose a joint (CB) energy signal (CB-ES) scheme providing both communication efficient transfer. By considering colluding eavesdroppers with imperfect channel state (CSI), formulate an optimization problem maximizing the secrecy rate between source legitimate receiver (IR) under constraints at relays constraint...
Water quality is an important factor affecting marine pasture farming. parameters have the characteristics of time series, showing instability and nonlinearity. Previous water prediction models are usually based on specific assumptions model parameters, which may limitations for complex environment systems. Therefore, in order to solve above problems, this paper combines long short-term memory (LSTM) backpropagation (BP) neural networks construct LSTM-BP combined parameter uses root mean...
Accurate acne severity grading is crucial for effective clinical treatment and timely follow-up management. Although some artificial intelligence methods have been developed to automate the process of grading, diversity image capture sources various application scenarios can affect their performance. Therefore, it's necessary design special evaluate them systematically before introducing into practice. To develop a deep learning-based algorithm that could accurately accomplish lesion...
The choroid is a vital vascular layer of the eye, essential for maintaining ocular health. Understanding its structural variations, particularly choroidal thickness (CT), crucial early detection diseases, such as age-related macular degeneration (AMD), high myopia (HM), and diabetes mellitus (DM). Recent advancements in deep learning have significantly improved segmentation measurement layers. This study aims to investigate age- gender-related changes CT components through analysis...
Macrophages exhibit heterogeneity and plasticity imbalance between pro-inflammatory anti-inflammatory macrophages plays a critical role in atherosclerosis progression. Telomerase reverse transcriptase (TERT) can be activated by nuclear factor-kappa B (NF-κB), but the regulation of telomerase activation on polarization remains unknown. We previously identified microRNA-216a (miR-216a) to promote inflammation through directly targeting Smad3/NF-κB pathway. The present study aimed assess...

Tobacco mosaic virus (TMV) has been studied as a multi-functional agent for bone tissue engineering. An osteo-inductive effect of wild-type TMV reported, it can significantly enhance the differentiation potential marrow stromal cells both on two-dimensional substrate and in three-dimensional (3D) hydrogel system. A mutant (TMV-RGD1) was created which featured adhesion peptide arginyl-glycyl-aspartic acid (RGD), most common motif responsible cell to extracellular matrix, surface particle...
The aquaculture of marine ranching is great significance for scientific and the practice statistically grasping existing information on types living resources their density. However, underwater environments are complex, there many small overlapping targets organisms, which seriously affects performance detectors. To overcome these issues, we attempted to improve YOLOv8 detector. InceptionNeXt block was used in backbone enhance feature extraction capabilities network. Subsequently, a separate...
We propose a novel joint user and full-duplex (FD) relay selection (JUFDRS) scheme to enhance physical layer security in multi-user multi-relay network. In this scheme, the FD decode-and-forward are selected such that capacity of end-to-end user-relay-destination channel is maximized ensure highest quality cooperative transmission.
