This paper reports a miniature indirect unipolar corona charger with multiple discharge sites for high efficiency in nanoparticle charging, sizing and detection. A novel scalable and stackable design using multiple multi-discharge-rings (MDR) allows simultaneous discharges at multiple sites along the inner perimeter of each ring and over the charger length, providing increased ion concentration (Ni) and more uniform ion distribution and, despite shorter particle residence time (t) due to a miniaturized charger size, achieving high Nit product and thus charging efficiency. MDRs with tungsten discharge tips were fabricated using a batch process and integrated with 3D-printed housing. Experimental results successfully verified functions and demonstrated high Nit (8.95×106) and low particle losses (3.25% at 10.55nm), both of which showed significant improvements (up to two orders of magnitude) compared to other miniature corona chargers. © 2025 IEEE.

Thanks to their long-range dependencies, transformers obtain state-of-the-art performance in diverse research fields such as computer vision and audio processing. In practical scenarios, convolutional neural networks (CNNs) are used more than Transformers due to their low complexity. So, Transformer-to-CNN knowledge distillation (KD) research, where the Transformer is the teacher and the CNN is the student, is in demand and receiving attention. In Transformer-to-CNN KD training, the capacity gap problem arising from structural differences between the teacher and student networks is the main factor of performance degradation of the student network, unlike homogenous architecture KD. However, previous KD studies transfer all of a teacher's knowledge to the student without consid-ering structural differences. They cannot overcome problems caused by structural differences and show poor performance in Transformer-to-CNN KD. In this paper, we iden-tify general and specific knowledge in feature maps of the teacher and student. General and specific knowledge are the generalized and non-generalized feature representation. We propose a novel KD framework DropKD, which extracts general knowledge from the teacher and student while re-moving specific knowledge and then allows general knowledge of the student network to learn general knowledge of the teacher. Our DropKD empowers the student network to achieve generalization by effectively managing general and specific knowledge. Through extensive experiments on challenging image classification datasets, we demonstrate that the proposed method is superior to existing methods. © 2025 IEEE.

Ethereum 2.0 is the second-largest cryptocurrency by market capitalization and a widely used smart contract platform. Therefore, examining the reliability of Ethereum 2.0's incentive mechanism is crucial, particularly its effectiveness in encouraging validators to adhere to the Ethereum 2.0's protocol. This paper studies the incentive mechanism of Ethereum 2.0 and evaluates its robustness by analyzing the interaction between block proposers and attesters in a single slot. To this end, we use Bayesian games to model the strategies of block proposers and attesters and calculate their expected utilities. Our results demonstrate that the Ethereum 2.0 incentive mechanism is incentive-compatible and promotes cooperation among validators. We prove that a Bayesian Nash equilibrium and an ex ante dominant strategy exist between the block proposer and attesters in a single slot. Our research provides a solid foundation for further analysis of Ethereum 2.0's incentive mechanism and insights for individuals considering participation as a validator in Ethereum 2.0. © 2024 Copyright is held by the owner/author(s).

Unmanned Aerial Vehicles (UAVs) will be critical infrastructural components of future smart cities. In order to operate efficiently, UAV reliability must be ensured by constant monitoring for faults and failures. To this end, the work presented in this paper leverages signal processing and Machine Learning (ML) methods to analyze the data of a comprehensive vibrational analysis to determine the presence of rotor blade defects during pre and post-flight operation. With the help of dimensionality reduction techniques, the Random Forest algorithm exhibited the best performance and detected defective rotor blades perfectly. Additionally, a comprehensive analysis of the impact of various feature subsets is presented to gain insight into the factors affecting the model's classification decision process. © 2024 IEEE.

Data seamlessly becomes a critical component for the state estimation and performance optimization of Cyber-Physical Systems (CPSs). Ensuring timely access to CPS data could be challenging due to operation costs, limited accessibility, security and connectivity, etc. CPS simulators have been thoroughly used in industry to synthesize CPS data. However, a common drawback for CPS simulators is the low integrity and fidelity of the synthesized data to the actual system. In this paper, we propose an extension, calibration, and validation to enhance the data synthesis integrity of an industrial CPS simulator. Behavior patterns are inferred from actual data, using frequency analysis, and applied to the simulation data synthesis, where a calibration using cross-correlation is utilized to fine-tune the data synthesis. According to the analysis results, our enhanced simulation data synthesis demonstrates a correlation of 93.7% to the actual CPS data. © 2024 IEEE.

We study the effect of simplified circuit level noise, consisting of the introduction of depolarizing errors at the input of any quantum gate, in two different implementations of a physical T gate. Both implementations use a magic state and Clifford operations, but one of them utilizes an additional ancilla that allows the reutilization of the magic state in future quantum operations. We assess the degradation experienced by the implemented T gates (due to error propagation) compared with ideal T gates by obtaining, as a function of the depolarizing probability, closed-form expressions for the probability of the error operators that may appear at the output. The resulting expressions match very well with results obtained through simulations and can be approximated by very simple formulas that provide additional insights. © 2025 IEEE.

RIS-Aided MIMO Downlink Transmission for Ultradense LEO Satellite-Terrestrial Networks

Ultradense low-Earth orbit (LEO) satellite-terrestrial network (ULSN) has evolved as a new paradigm to provide ubiquitous and high-capacity communications in next generation wireless networks. However, the direct LEO satellite broadband connectivity faces significant challenges in urban environments due to the masking effect, which limits the reliability and availability of communication links in ULSNs. To address this, reconfigurable intelligent surface (RIS) is emerging as a promising solution in ULSNs. In this article, we investigate RIS-aided downlink data transmission in urban environments of multiusers in ULSNs. We set up a mixed-integer programming (MIP) model for maximizing the sum rate of terrestrial users in ULSNs. To solve the complex MIP problem, we propose a two-phase joint optimization algorithm with a deep learning phase and an alternative optimization (AO) phase. In the deep learning phase, a deep neural network (DNN) algorithm is employed to obtain the optimal user association matrix based on the positions of terrestrial users and LEO satellites. Then in the AO phase, successive convex approximation is utilized to transform the nonconvex subproblems of beamforming and RIS phase design into convex formulations and iteratively solve them. Simulation results demonstrate that the proposed algorithm outperforms other baseline algorithms. © 2014 IEEE.

Large language models (LLMs) are rapidly emerging in Artificial Intelligence (AI) applications, especially in the fields of natural language processing and generative AI. Not limited to text generation applications, these models inherently possess the opportunity to leverage prompt engineering, where the inputs of such models can be appropriately structured to articulate a model's purpose explicitly. A prominent example of this is intent-based networking, an emerging approach for automating and maintaining network operations and management. This paper presents semantic routing to achieve enhanced performance in LLM-assisted intent-based management and orchestration of 5G core networks. This work establishes an end-to-end intent extraction framework and presents a diverse dataset of sample user intents accompanied by a thorough analysis of the effects of encoders and quantization on overall system performance. The results show that using a semantic router improves the accuracy and efficiency of the LLM deployment compared to stand-alone LLMs with prompting architectures. © 2024 IEEE.

In this paper, we analyze covert amplify-and-forward (AF) relay networks with a metric for measuring the data freshness, i.e, age of information (AoI), with aid of the cooperative jammer that generates artificial noise (AN) to protect from Warden Willie's surveillance. We first derive lower boundary of covertness, average AoI and formulate an average AoI minimization problem by optimizing the jamming power of the cooperative jammer. Our analysis shows that the optimal jamming power is the minimum value that satisfies the lower boundary of covertness, which varies depending on the prior probability. © 2023 IEEE.
