Accurately identifying optical fiber vibration signals is crucial for ensuring the proper operation of perimeter security warning systems. To enhance recognition accuracy intrusion events detected by distributed acoustic sensing system (DAS) based on phase-sensitive time-domain reflectometer (φ-OTDR) technology, we propose an identification method that combines empirical mode decomposition (EMD) with convolutional neural networks (CNNs) and long short-term memory (LSTM) networks. First, EMD...
Aqueous K2CO3 solution is a promising absorbent in removing CO2 from gas mixtures using hollow fiber membrane contactor (HFMC). The use of amino acid salts (AASs) as promoter solutions may further improve absorption performance. In this study, two-dimensional mathematical model was developed to simulate the process an HFMC, where potassium glycinate (PG), lysine (PL), and arginine (PA) were considered promoters solution. performances with without analyzed theoretically. effects operating...
Abstract Ovarian cancer poses a significant threat to women’s health, with conventional treatment methods encountering numerous limitations, and the emerging engineered bacterial anti-tumor strategies offer newfound hope for ovarian treatment. In this study, we constructed VNP20009-Abvec-Igκ-MIIP (VM) strain conducted initial assessments of its in vitro growth performance expression capability migration/invasion inhibitory protein (MIIP). Subsequently, ID8 cells mouse models were investigate...
New carbonyl sulfoxonium ylide glyco-reagents have been developed, enabling the synthesis of versatile heteroarene C-glycosides through a Ru-catalyzed C–H activation/annulation strategy. These reactions tolerate various saccharide donors and represent significant advance in stereoselective heterocyclic C-glycosides. Furthermore, strategy methods could be applied to large-scale late-stage modifications some structurally complex natural products or drugs.
This paper investigates physical layer secure communication in a wideband wireless system, where base station (BS) equipped with an extremely large scale antenna array (ELAA) transmits confidential information to legitimate receiver under the threat of potential eavesdropper. Due high carrier frequency and aperture, both eavesdropper lie near-field region BS. In order mitigate beam split effect reduce hardware cost, true-time delayer-based hybrid beamfocusing architecture is designed. Then,...
The rapid expansion of e-commerce has led to product oversaturation on online platforms. To help users find their preferred products in a more efficient and accurate way, many platforms have introduced personalized recommendation systems. Collaborative filtering is one the most successful techniques, while its improvement, Invariant Filtering (Inv-CF), aims address popularity bias problem traditional CF models by capturing unbiased preferences that remain constant despite change...
For the high density of users and accompanying network service requirements in cellular system, Device-to-Device (D2D) communication is a promising technology to cope with increasing wireless traffic demands by reusing spectrum resources. In practice, signal easy be eavesdropped D2D communications underlaying networks, hence, ensuring secure for user equipments (CUEs) an urgent meaningful problem. this paper, we propose joint subcarrier power allocation scheme maximizing sum data rate pairs,...

This letter makes a first attempt to design cooperative relay scheme secure wireless communications by adopting fast-forward full-duplex (F3D) node. Different from the conventional relay, F3D node could process and forward received signal immediately. With such forwarding, forwarded of enhance interference plus noise ratio receiver, whereas weaken that eavesdropper thus build up channel. Beyond proposed scheme, we move optimize processing with target maximizing secrecy capacity. The...
This letter considers a new secure communication scenario where full-duplex transmitter (Alan) needs to transmit confidential information half-duplex receiver (Bob), with an eavesdropper (Eve) that tries overhear the information. For realizing communication, we design effective artificial-noise-aided scheme (ANAS) which is composed of two phases' transmissions: in Phase 1, Alan and Bob independent artificial noises (ANs) simultaneously, while 2, superimposes AN received 1 its signal sends...
This letter attempts to design a surveillance scheme by adopting an active reconfigurable intelligent surface (RIS). Different from the conventional passive RIS, RIS could not only adjust phase shift but also amplify amplitude of reflected signal. With such reflecting, signal jointly noise ratio (SNR) suspicious receiver and legitimate monitor, hence proactive eavesdropping at physical layer be effectively realized. We formulate optimization problem with target maximizing rate obtain optimal...
The in-band full-duplex (IBFD) wireless communication has been spotlighted as one of the promising technologies to enhance throughput performance in future WLANs. One way leverage capability practical scenario is enable three-node transmission, where a access point (AP) transmits date half-duplex user while receives from another user. Such mode, however, introduces extra uplink-downlink interference, which may degrade gain. In this paper, with target fully achieving improvement brought by we...

Specifically, with target of securing VAA-aided D2DM under threat multiple eavesdroppers, we propose secure beamforming scheme by jointly considering formed Base Station (BS). For obtaining optimal beamforing vectors, nonsmooth...
MoS2 has excellent vacuum lubricating performance. However, it is prone to be oxidized in a high-temperature atmospheric environment, leading the deterioration of its performance and even serious space accidents. The MoS2-based solid materials can improved some extent by co-compounding appropriate oxides Ag. tribological properties several common nano-oxides (ZnO, TiO2, Al2O3, ZrO2) composited with metal Ag composites were compared at 450 °C. results showed that comprehensive MoS2-TiO2-Ag...
