Microservices have been widely used in enterprises due to their excellent scalability and timely update capabilities. However, while the fine-grained modularity and service orientation decrease the complexity of system development, the complexity of system operation and maintenance has been greatly increased because system faults are becoming very frequent and complex. Therefore, fault localization, that is, diagnosing fault service and its root cause, is very important yet challenging for microservice applications. One of the most challenges of fault localization is fusing multiple data sources because system faults will exhibit different features in multiple data sources. Therefore, it is necessary to fuse multiple data sources and build a unified model for fault localization. In this paper, we propose a fault localization approach with the fusion of system logs and monitoring metrics. Our approach first discovers service dependencies and then utilizes system logs and monitoring metrics to detect anomalies for each microservice. Finally, it locates the fault service and recommends the root cause system metrics based on the service dependencies and detected anomalies. The experiment results show that the average precision of our approach is ~75%. © 2022 IEEE.

The application of hybrid pixel detectors with a dynamically selectable readout mode in X-ray imaging is highly desirable. The concept of a detector system that can switch readout mode under different conditions is demanded to realize fast and versatile imaging. This paper presents design techniques and preliminary results of a pixel readout ASIC prototype with a reconfigurable readout scheme in a 180 nm CMOS process for silicon pixel detectors. A bus-based reconfigurable data readout scheme is presented. Three readout modes are realized: full-frame readout, zero-suppression readout, and region-of-interest readout. In particular application scenarios, the readout mode will be switched based on the number of pixels with valid data to improve the frame rate. Assuming that all pixels with valid data are transmitted, the reconfigurable data readout method saves 40 % of the data transmission time than zero-suppression readout under 50 MHz. © 2022 IEEE.

The open array chip is an incredibly valuable tool for analyzing single molecule levels. Its efficiency, speed, compatibility, and precision make it an essential part of this process. However, efficient sample addition has become a significant challenge in the development of open array chips due to the coupling of the solid-liquid interface and the need for high-precision control. To address this challenge, we have developed an integrated adding sample device using technology of generates and detects controllable droplets array based on an open array chip with a biomimetic structure. This device combines a microfluidic chip, image detection, and smear speed regulation. We have studied the factors that affect the efficiency of sample loading, such as the number, speed and fluctuation of smears, and microwell size. The experiments have shown that the open array chip with the microwell’s diameter of 350 µm can generate arrays of ~470/cm2 ~8 nL droplets, significantly reducing controlled speed fluctuation errors by7.24% and volume fluctuation errors by 24% compared to traditional manual ways. The device has also displayed excellent performance on chips with microwell diameters of 120, 350, 700, and 1300 µm, respectively, with a notable first-time success rate of up to 91% on chips with microwell diameters of 120 µm. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

In the field of cryptography and security, minimizing the number of AND gates within logic networks is crucial. Such optimization significantly influences the multiplication complexity of circuits. This paper proposes a Quantified Boolean Formulas (QBF) based resynthesis to dynamically construct local circuits from sub-circuits, with the goal of minimizing the number of AND gates and optimizing the number of XOR gate numbers in well-optimized networks. Experimental results on parts of the EPFL benchmarks suite indicate that the proposed method effectively reduces the number of AND gates by 15.51 % and the number of XOR gates by 3.34%.

In this paper, we adopt a powerful deep neural network (DNN) to tackle the problems of detecting car license plates (LPs) and recognizing Arabic letters in natural scene images. Our Automatic License Plate Recognition (ALPR) system is built using state-of-the-art methodologies and techniques to provide the optimal speed/accuracy trade-off at each level. Images of vehicles and Moroccan and European LPs were used to train the neural networks. The system was able to correctly detect and recognize in the test set all the characters existing in a LP with an accuracy of 91.11% and 98.89% taking into account that only one character is misread. Using a high-end GPU, our system likewise produced outstanding real-time execution results. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Mixed Structural Choice Operator: Enhancing Technology Mapping with Heterogeneous Representations

arXiv 2025年

作者： Hu, Zhang Pan, Hongyang Xia, Yinshui Wang, Lunyao Chu, Zhufei Faculty of Electrical Engineering and Computer Science Ningbo University Ningbo315211 China School of Microelectronics State Key Laboratory of Integrated Chips and System Fudan University Shanghai200433 China

—The independence of logic optimization and technology mapping poses a significant challenge in achieving high-quality synthesis results. Recent studies have improved optimization outcomes through collaborative optimization of multiple logic representations and have improved structural bias through structural choices. However, these methods still rely on technology-independent optimization and fail to truly resolve structural bias issues. This paper proposes a scalable and efficient framework based on Mixed Structural Choices (MCH). This is a novel heterogeneous mapping method that combines multiple logic representations with technology-aware optimization. MCH flexibly integrates different logic representations and stores candidates for various optimization strategies. By comprehensively evaluating the technology costs of these candidates, it enhances technology mapping and addresses structural bias issues in logic synthesis. Notably, the MCH-based lookup table (LUT) mapping algorithm set new records in the EPFL Best Results Challenge by combining the structural strengths of both And-Inverter Graph (AIG) and XOR-Majority Graph (XMG) logic representations. Additionally, MCH-based ASIC technology mapping achieves a 3.73% area and 8.94% delay reduction (balanced), 20.35% delay reduction (delay-oriented), and 21.02% area reduction (area-oriented), outperforming traditional structural choice methods. Furthermore, MCH-based logic optimization utilizes diverse structures to surpass local optima and achieve better results. Copyright © 2025, The Authors. All rights reserved.

The aim of this paper is to propose a new mathematical model able to compute the electro-thermal performance of a Gate All Around (GAA)-FET transistors. The given electrical formulation is given by the Drift-Diffusion (D-D) model in conjunction with an effective electron mobility formulation. To better compute the nano heat conduction, the enhanced D-D model is coupled with the hydrodynamic model. To achieve high evidence to the proposed model, the simulation of the transfer and output characteristics are compared with experimental and numerical data, and we have succeeded to achieve a good concordance. Power dissipation with phonon radiation effect, device temperature has been studied in 50 nm and 10 nm of GAAFET gate lengths. We have shown that, the Joule effect increases with the decreases of the GAAFET gate length. On the other hand, we demonstrate that for the two studied structure, the saturated temperature from 360 K to 405 K when the device gate length increases from 10 nm to 50 nm, respectively.
