Meta Network for Flow-Based Image Style Transfer
No full textA style transfer aims to produce synthesized images that retain the content of one image while adopting the artistic style of another. Traditional style transfer methods often require training separate transformation networks for each new style, limiting their adaptability and scalability. To address this challenge, we propose a flow-based image style transfer framework that integrates Randomized Hierarchy Flow (RH Flow) and a meta network for adaptive parameter generation. The meta network dynamically produces the RH Flow parameters conditioned on the style image, enabling efficient and flexible style adaptation without retraining for new styles. RH Flow enhances feature interaction by introducing a random permutation of the feature sub-blocks before hierarchical coupling, promoting diverse and expressive stylization while preserving the content structure. Our experimental results demonstrate that Meta FIST achieves superior content retention, style fidelity, and adaptability compared to existing approaches.補正完畢CH
Self‑Attention GAN for Electromagnetic Imaging of Uniaxial Objects
No full textThis study introduces a Self-Attention (SA) Generative Adversarial Network (GAN) framework that applies artificial intelligence techniques to microwave sensing for electromagnetic imaging. The approach involves illuminating anisotropic objects using Transverse Magnetic (TM) and Transverse Electric (TE) electromagnetic waves, while sensing antennas collecting the scattered field data. To simplify the training process, a Back Propagation Scheme (BPS) is employed initially to calculate the preliminary permittivity distribution, which is then fed into the GAN with SA for image reconstruction. The proposed GAN with SA offers superior performance and higher resolution compared with GAN, along with enhanced generalization capability. The methodology consists of two main steps. First, TM waves are used to estimate the initial permittivity distribution along the z-direction using BPS. Second, TE waves estimate the x- and y-direction permittivity distribution. The estimated permittivity values are used as inputs to train the GAN with SA. In our study, we add 5% and 20% noise to compare the performance of the GAN with and without SA. Numerical results indicate that the GAN with SA demonstrates higher efficiency and resolution, as well as better generalization capability. Our innovation lies in the successful reconstruction of various uniaxial objects using a generator integrated with a self-attention mechanism, achieving reduced computational time and real-time imaging.補正完畢CH
Novel membrane-integrated ultrasonic atomization system for energy-efficient treatment of dye-polluted wastewater
No full textDye-contaminated wastewater must be treated before its release into water bodies, as it poses serious environmental and health concerns. Although conventional methods involving pressure-driven membrane separation processes are widely used to treat dye-containing wastewater, they are often energy-intensive due to high-pressure requirements. To overcome these limitations, this study introduces a novel ultrasonic atomizing membrane system designed for energy-efficient dye removal from wastewater. This innovative system consists of a membrane composite fabricated via deposition of a thin, selective chitosan-crosslinked GO (GO-CS) layer on a commercial polyamide substrate, integrated into a high-frequency ultrasonic atomizer. The addition of CS chemically modified GO, which resulted in enhanced hydrophilicity and increased surface charge of the composite membrane. The ultrasonic atomizing membrane system exhibited a high pure water flux of up to 129 ± 13 LMH. With the GO-CS (v/v = 1/0.5) membrane composite, the system achieved impressive dye rejection rates of 90 % for methyl orange (MO) and 99 % for both Congo red (CR) and disperse blue 1 (DB1). The stability test showed sustained performance with a 99 % CR rejection rate and a flux of 60.0 ± 10.6 LMH. Reusability test further confirmed high membrane efficiency, with 93 – 99 % CR rejection and a permeation flux of 85.5 ± 3.6 LMH. These findings prove that the proposed novel ultrasonic atomizing membrane system could be an effective energy-saving alternative for the treatment of dye-contaminated wastewater.補正完畢NL

Convergence of Technological Social Changes in the Development of Intelligent Technology Innovation System in Taiwan
No full textHow do intelligent technology innovation systems develop? How do institutional factors influence the development of innovation systems? This study adopted the National/Sectoral Innovation System as the main framework to study the dynamics of intelligent technology innovation system in Taiwan. Combining scientometric mapping, social network analysis, Multi Criteria Decision-Making (MCDM), and 33 interviews to understand the interactions between key stakeholders and the institutions in the intelligent technology sector in Taiwan. The results show that a relatively large proportions of foreign technologies are widely adopted into the system through international business networks. Regarding commercial applications, firms prefer to introduce foreign technology through international business networks. This illustrates the needs of commercializations of domestic technological research and development. The future policy should promote academia-industry collaborations to enhance the commercializations of scientific research outcomes. This research contributes to enhance the knowledge flow in the innovation system, thus, to upgrade the national capabilities of small emerging economies in East Asia.補正完畢IN
Zhang-Rice Singlets State Formed by Two-step Oxidation for Triggering Water Oxidation under Operando Conditions
No full textThe production of ecologically compatible fuels by electrochemical water splitting is highly desirable for modern industry. The Zhang-Rice singlet is well known for the superconductivity of high-temperature superconductors cuprate, but is rarely known for an electrochemical catalyst. Herein, we observe two steps of surface reconstruction from initial catalytic inactive Cu1+ in hydrogen treated Cu2O to Cu2+ state and further to catalytic active Zhang-Rice singlet state during the oxygen evolution reaction for water splitting. The hydrogen treated Cu2O catalyst exhibits a superior catalytic activity and stability for water splitting and is an efficient rival of other 3d-transition-metal catalysts. Multiple operando spectroscopies indicate that Zhang-Rice singlet is real active species, since it appears only under oxygen evolution reaction condition. This work provides an insight in developing an electrochemical catalyst from catalytically inactive materials and improves understanding of the mechanism of a Cu-based catalyst for water oxidation.補正完畢US
Self-Adaptive Dual-Site Synergy with an Optimized Electronic Configuration for Overall Water Splitting in Acidic Media
No full textIn harsh acidic environments, there remains a demand for catalysts that possess both high activity and stability, enabling them to efficiently enhance the slow kinetics of the hydrogen evolution reaction and oxygen evolution reaction, which are crucial for the advancement of proton exchange membrane water electrolyzers. Herein, a bifunctional electrocatalyst was designed by synergistically modulating the electronic and coordination properties. The IrOx/MnOx catalyst was successfully created, surpassing the activity and stability limitations of IrO2 catalysts for acidic overall water splitting, thereby pushing the boundaries of electrocatalytic performance. When used as both electrodes in an overall water-splitting cell, the IrOx/MnOx catalyst achieved a current density of 10 mA cm–2 at 1.51 V for 36 h without any noticeable degradation, which greatly outperformed the commercial couples (Pt/C||IrO2, 1.65 V) in acidic media. Of greater significance, X-ray absorption spectroscopy deciphered that the unsaturated Ir centers, which have an electron-rich nature, can lower energy barriers associated with the proton adsorption and desorption and oxygenated reactant species through a self-adaptive surface reconstruction process. This work introduces an approach to boost the intrinsic performance of catalysts for overall water splitting by constructing unsaturated coordination centers, offering a promising strategy for catalyst design.補正完畢US
Sanitizing diffusion-generated images via fingerprint removal and adversarial perturbation for forensic evasion
No full textDiffusion models have rapidly advanced the realism of synthetic image generation, posing new challenges for forensic detectors. This paper proposes a two-stage forensic evasion framework designed to undermine the detectability of diffusion-generated images. In the first stage, a spectrum-aware generative adversarial network (GAN) removes frequency-domain fingerprints that are commonly exploited by forensic models. In the second stage, adversarial perturbations are applied using the Iterative Fast Gradient Sign Method (I-FGSM) to further mislead detectors while preserving visual fidelity. Experiments conducted on COCO-based datasets demonstrate that our method significantly reduces detection accuracy across multiple state-of-the-art forensic models, including UniFD, DIGBD, and SSIP. Furthermore, we show that combining fingerprint removal with adversarial perturbation achieves stronger evasion than either method alone. Ablation studies also highlight the benefits of adaptive perturbation strengths and data augmentation for enhancing cross-model evasion. This work reveals critical vulnerabilities in current forensic approaches and underscores the need for more robust detection systems against adaptive evasion補正完畢TW
