| ○ | ○ | Article | Evaluation of the Effect of Agricultural Return Flow on Water Quality, Water Quantity and Aquatic Ecology in Downstream Rivers | Agricultural water serves various functions, including public interest purposes, beyond its primary role in agricultural production. In order to evaluate the various public interest purposes of agricultural water, a quantified study of the effect of agricultural water on river flow, water quality, and aquatic ecosystems is needed. Therefore, this study quantified the impact of agricultural water on the environmental and ecological maintenance function of downstream rivers, taking into account the return flow of agricultural water in rural areas. To this end, first, the effect of agricultural return flow on river maintenance function was evaluated by comparing the return flow quantity calculated using the reservoir supply data with the simulated river flow rate through the SWAT model. Second, the effect of the agricultural return flow on the downstream river environmental ecological function was analyzed using the optimal flow rate results calculated through the PHABSIM model. The lastly, the effect of agricultural water by farming period on the water quality of downstream rivers was analyzed. As a result of the analysis, it was found that the return flow of agricultural water had a large effect on the river flow rate in the case of the non-rainy season, but the optimal ecological flow rate was not satisfied. In the case of river water quality, it was confirmed that the effect of agricultural water (mainly considered as a pollutant) was not significant, except for the drainage duration of rice paddies. Therefore, it can be understood that agricultural water is not only used for the purpose of production but can also have a positive impact on the aquatic ecology of downstream rivers. | Kang, Taeseong; Shin, Yongchul; Shin, Minhwan; Lee, Dongjun; Lim, Kyoung Jae; Kim, Jonggun | EM Res Inst, Chuncheon Si 24408, South Korea; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Auburn Univ, Coll Forestry Wildlife & Environm, Auburn, AL 36849 USA; Kangwon Natl Univ, Dept Reg Infrastructure Engn, Daegu 24341, South Korea | 58962436600; 55659438100; 35206690500; 57204651341; 35176071700; 35435507500 | kangstar2003@naver.com;jgkim@kangwon.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 11 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0 | 2025-05-07 | 0 | 0 | agricultural return flow; SWAT model; PHABSIM model; water quality; aquatic ecology | agricultural return flow; aquatic ecology; PHABSIM model; SWAT model; water quality | Nigeria; Rivers; Agriculture; Aquatic ecosystems; Flow rate; Function evaluation; Quality control; Reservoirs (water); Water pollution; Water quality; Agricultural return flow; Agricultural water; Aquatic ecology; Down-stream; PHABSIM; PHABSIM model; Public interest; Return flow; River flow; SWAT model; agricultural production; aquatic ecosystem; ecosystem function; flow pattern; irrigation; river flow; river water; soil and water assessment tool; water quality; Rivers | English | 2024 | 2024-06 | 10.3390/w16111604 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Fluid-Structure Interaction Analysis of Ascendable Horizontal-Bar Wastewater Screen for Enhanced Trapping Performance | Wastewater accumulates debris as it moves through sewage systems and must undergo purification at treatment plants, where insoluble debris is screened at the inlet. Previous studies have focused on screening mechanisms using rotating or ascendible sub-screens with vertical bars, and the effects of horizontal bars on structural integrity and fluid flow have not yet been explored. The present study addresses this gap by proposing a novel screening mechanism with horizontal bars and providing insights into flow behaviour and structural performance. The proposed mechanism consists of a main screen, an ascendible sub-screen and a rake system, and its effects on the flow distribution inside the channel and the resulting deformations and stress affecting the mechanism are computationally analysed. The problem is modelled as a fluid-structure interaction and solved using the arbitrary Lagrangian-Eulerian approach. Velocity distribution, structural deformation and stress are analysed for the various inlet flow velocities and critical configurations of the screening mechanism. The sub-screen in the proposed mechanism exhibited reduced deformation (0.9 mm for vertical bars and 0.2 mm for horizontal bars versus 2.2 mm in previous vertical-only designs). The maximum von Mises stress values were well below the 250 MPa yield strength, with peak stresses of 3.8 MPa in the sub-screen and 0.23 MPa in the main screen. Key operating conditions causing flow separation and velocity fluctuations are identified, and design improvements are suggested. The study provides guidelines for manufacturing and operating wastewater-screening mechanisms whilst mitigating undesirable performance and minimising deformation and stress in the mechanism. | Memon, Safi Ahmed; Akhtar, Shehnaz; Chae, Hyeon-Bae; Choi, Du-Whan; Das, Raj; Park, Cheol-Woo | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehakro, Bukgu 41566, Daegu, South Korea; Univ Ulsan, Sch Mech Engn, Ulsan 44610, South Korea; I ENTEC Co Ltd, 18 Gil 33 Seongseogongdanbukro, Daegu 42712, South Korea; RMIT Univ, Sch Engn, 124 Trobe St, Melbourne, Vic 3000, Australia | ; Akhtar, Shehnaz/IST-0523-2023 | 58757911600; 57202696797; 59075600000; 59076132900; 9638587900; 7408416474 | raj.das@rmit.edu.au;chwoopark@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 24 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0 | 2025-05-07 | 0 | 0 | wastewater-screening mechanism; fluid-structure interaction; flow separation; deformation; von Mises stress | LAGRANGIAN-EULERIAN METHOD; OPTIMIZATION; NANOSCALE | deformation; flow separation; fluid–structure interaction; von Mises stress; wastewater-screening mechanism | Crystal lattices; Fluid structure interaction; Levees; Religious buildings; Screening; Sewage treatment plants; Solar buildings; Structural analysis; Deformation and stress; Fluid structure interaction analysis; Fluid-structure interaction; Horizontal bars; Performance; Screening mechanism; Sewage system; Treatment plants; VonMises stress; Wastewater-screening mechanism; fluid flow; manufacturing; purification; separation; sewage; wastewater treatment; Inlet flow | English | 2024 | 2024-12 | 10.3390/w16243671 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Immune Checkpoint-Blocking Nanocages Cross the Blood-Brain Barrier and Impede Brain Tumor Growth | Glioblastoma (GBM) is the deadliest tumor of the central nervous system, with a median survival of less than 15 months. Despite many trials, immune checkpoint-blocking (ICB) therapies using monoclonal antibodies against the PD-1/PD-L1 axis have demonstrated only limited benefits for GBM patients. Currently, the main hurdles in brain tumor therapy include limited drug delivery across the blood-brain barrier (BBB) and the profoundly immune-suppressive microenvironment of GBM. Thus, there is an urgent need for new therapeutics that can cross the BBB and target brain tumors to modulate the immune microenvironment. To this end, we developed an ICB strategy based on the BBB-permeable, 24-subunit human ferritin heavy chain, modifying the ferritin surface with 24 copies of PD-L1-blocking peptides to create ferritin-based ICB nanocages. The PD-L1pep ferritin nanocages first demonstrated their tumor-targeting and antitumor activities in an allograft colon cancer model. Next, we found that these PD-L1pep ferritin nanocages efficiently penetrated the BBB and targeted brain tumors through specific interactions with PD-L1, significantly inhibiting tumor growth in an orthotopic intracranial tumor model. The addition of PD-L1pep ferritin nanocages to triple in vitro cocultures of T cells, GBM cells, and glial cells significantly inhibited PD-1/PD-L1 interactions and restored T-cell activity. Collectively, these findings indicate that ferritin nanocages displaying PD-L1-blocking peptides can overcome the primary hurdle of brain tumor therapy and are, therefore, promising candidates for treating GBM. © 2023 The Authors.

| ○ | ○ | Article | Investigating Algal Sensor Utilization Methods for Three-Dimensional Algal Control Technology Evaluation | There are physical, chemical, and biological methods to control algae, and their efficiency requires evaluation. In the field, monitoring and evaluating the overall algal concentration is challenging due to factors such as the flow rate, inhomogeneous distribution of algae in the water body, and limitations in the number of samples for microscopic analysis. In this study, we analyzed total and cyanobacterial chlorophyll a (Chl-a) using a FluoroProbe sensor and microscopic data collected from March to November 2019. The Pearson correlation coefficient of log(x + 1) values revealed a significant positive correlation between four harmful cyanobacteria and cyanobacterial Chl-a (r = 0.618, p < 0.01). Furthermore, we explored the potential of evaluating the efficiency of algal control using sensors by acquiring three-dimensional, spatially continuous data for an algal fence, a physical algae control technology installed at the Daecheong Dam in 2021. The results confirmed that sensors can effectively evaluate algal control technology. This study demonstrates the effectiveness of using sensors to assess the efficiency of physical algal control. | Park, Yeon-Jeong; Yi, Hye-Suk; Youn, Seok-Jea; Lee, Seung-Jae; Jin, Deok-Hyeon; Lee, Hee-Suk; Kim, Han-Soon | Kyungpook Natl Univ, Dept Biol, Daegu 41566, South Korea; Korea Water Resources Corp K Water, Daejeon 34350, South Korea | Park, Yeonjeong/B-9146-2011 | 56412226100; 57203970498; 57216036845; 59196805300; 59196805400; 57204157438; 7410135359 | twins200338@gmail.com;yihs@kwater.or.kr;sjyoun@kwater.or.kr;dlsjb@kwater.or.kr;jindh0831@naver.com;lovealga@kwater.or.kr;kimhsu@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 12 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0.99 | 2025-05-07 | 2 | 2 | cyanobacteria; algal control; effect assessment method; sensing; field application | CYANOBACTERIAL BLOOMS; WATER-TREATMENT; CLIMATE-CHANGE; IN-VIVO; GLOBAL EXPANSION; PHYTOPLANKTON; MICROCYSTIS; MANAGEMENT; RESERVOIR; DYNAMICS | algal control; cyanobacteria; effect assessment method; field application; sensing | Daecheong Dam; South Korea; Taejon [South Korea]; Algae; Correlation methods; Algal controls; Chlorophyll a; Control technologies; Cyanobacterium; Effect assessment method; Effect assessments; Field application; Physical methods; Sensing; Technology evaluation; chlorophyll a; cyanobacterium; detection method; sensor; Efficiency | English | 2024 | 2024-06 | 10.3390/w16121679 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Mesozoic transpressional structural inversion and synkinematic crustal fluid circulation around the northeastern Chungnam basin, southwestern Korean Peninsula: Tectonic implications | This study explores the coupled processes of structural inversion and fluid migration around the northeastern part of the Mesozoic Chungnam Basin in the southwestern Korean Peninsula, focusing on quartz vein systems genetically linked to an orogenic gold deposit. Our results show that the inversion structures reflect the coexistence of strike-slip simple shear and pure shear components caused by NW-SE crustal shortening, leading to a transpressional deformation model. The quartz veins, filling the high-angle faults with a reverse slip component and adjacent hydrofractured wall rocks, represent transient fluid flow related to seismic faulting and fault valving during the inversion. New K-Ar ages of illite polytypes in fault gouges, determined using the Illite-ageanalysis (IAA) method, indicate Late Jurassic-Early Cretaceous fault reactivations. Notably, ca. 160 Ma 2M1 illite age from a fault zone filled with an orogenic gold-bearing quartz vein indicates that the inversion and auriferous hydrothermal fluid flow started with a magmatic quiescence in the southern Korean Peninsula likely owing to the flat subduction of the Paleo-Pacific Plate. Our findings suggest that the orogenic gold-bearing vein system was likely sourced from the subcrustal metamorphic fluid in the flat subduction zone of the Mesozoic East Asian Continental margin. | Kwak, Yujung; Park, Seung-Ik; Park, Changyun; Song, Yungoo; Smeraglia, Luca | Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea; Yonsei Univ, Dept Earth Syst Sci, Seoul 03722, South Korea; Natl Res Council Italy, CNR, IGAG, Rome, Italy | ; Smeraglia, Luca/HKO-7843-2023 | 57798903000; 55832472000; 56197393100; 7404920759; 56458848300 | psi@knu.ac.kr; | JOURNAL OF STRUCTURAL GEOLOGY | J STRUCT GEOL | 0191-8141 | 1873-1201 | 180 | SCIE | GEOSCIENCES, MULTIDISCIPLINARY | 2024 | 2.9 | 35.5 | 0 | 2025-05-07 | 0 | 1 | Structural inversion; Transpression; Fault valve; Hydrothermal fluid; Orogenic gold | FAULT-VALVE BEHAVIOR; FLAT-SLAB SUBDUCTION; REPUBLIC-OF-KOREA; HUTTI GOLD MINE; OROGENIC GOLD; GYEONGGI MASSIF; SOUTH-KOREA; TECTONOMAGMATIC EVOLUTION; PLUTONIC ROCKS; SHEAR ZONES | Fault valve; Hydrothermal fluid; Orogenic gold; Structural inversion; Transpression | Korea; Fault slips; Gold deposits; Quartz; Fault-valve; Flat subductions; Gold bearings; Hydrothermal fluids; Mesozoic; Orogenic gold; Quartz vein; Structural inversion; Transpression; Vein systems; continental margin; deformation; fluid dynamics; hydrothermal fluid; Mesozoic; strike-slip fault; subduction zone; tectonic evolution; tectonic setting; transpression; Flow of fluids | English | 2024 | 2024-03 | 10.1016/j.jsg.2024.105070 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Microbial Ecosystems as Guardians of Food Security and Water Resources in the Era of Climate Change | In the era of climate change, the correlation between climate, food security, and water resources is profoundly influenced by microbial ecosystems. This review explores the important role of these often-overlooked microorganisms in maintaining the delicate balance required for sustainable agriculture and clean water availability. Microbes, though minuscule, orchestrate vital processes shaping nutrient cycling, soil health, and ecosystem functionality in both terrestrial and aquatic domains. As climate shifts occur, these adaptable microbes adjust, affecting ecosystem dynamics. Climate-smart agriculture harnesses microbial partnerships for soil carbon sequestration and stress mitigation, safeguarding the food supply. Microbes support crop productivity and resilience while also managing pests and diseases in changing climates. Additionally, they contribute to water purification and quality stabilization through water treatment and biofilms, ensuring clean water resources. Microbial diversity acts as a buffer against climate-induced disruptions, underlining their role in sustaining ecosystem stability. Integrating microbial approaches into policies and practices becomes crucial for climate adaptation, paving the way for sustainable agriculture and water management. Novel microbial technologies hold promise in addressing climate-food-water challenges, while collaborative research remains essential for innovative solutions at this critical interface of science and policy. Moreover, microbial ecosystems emerge as essential to food security and water resources in the face of climate change, charting a path towards a resilient and sustainable future. | Toor, Muhammad Danish; Rehman, Muneeb Ur; Abid, Javeria; Nath, Dibyajyoti; Ullah, Izhar; Basit, Abdul; Din, Muhammad Mughees Ud; Mohamed, Heba I. | Univ Tartu, Inst Ecol & Earth Sci, Fac Sci & Technol, Tartu, Estonia; Agr Univ, Fac Agron, Dept Agrochem & Soil Sci, Plovdiv, Bulgaria; Chinese Acad Agr Sci, Agr Genom Inst Shenzhen, Shenzhen 518120, Peoples R China; Dr Rajendra Prasad Cent Agr Univ, Dept Soil Sci, Samastipur 848125, Bihar, India; Ondokuz Mayis Univ, Fac Agr, Dept Hort Sci, Samsun, Turkiye; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Univ Agr Faisalabad, Inst Soil & Environm Sci, Faisalabad, Pakistan; Ain Shams Univ, Fac Educ, Biol & Geol Sci Dept, Cairo 11341, Egypt | Nath, Dibyajyoti/JNS-5062-2023; Basit, Abdul/AAX-2414-2021; Ullah, izhar/MYR-3437-2025; mohamed, heba/U-8673-2019 | 57375664400; 59366470300; 59367210200; 58510196600; 57211559793; 58696991300; 58033069900; 37102371200 | hebaibrahim79@gmail.com; | WATER AIR AND SOIL POLLUTION | WATER AIR SOIL POLL | 0049-6979 | 1573-2932 | 235 | 11 | SCIE | ENVIRONMENTAL SCIENCES;METEOROLOGY & ATMOSPHERIC SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0.65 | 2025-05-07 | 5 | 4 | Adaptation; Climate change; Food security; Microbial ecosystems; Resilience; Sustainable agriculture; Water resources | PLANT-GROWTH; ELEVATED CO2; COMMUNITY COMPOSITION; ENZYME-ACTIVITIES; SOIL RESPIRATION; RESILIENCE; BIODIVERSITY; TEMPERATURE; RESPONSES; BACTERIA | Adaptation; Climate change; Food security; Microbial ecosystems; Resilience; Sustainable agriculture; Water resources | calcium carbonate; fertilizer; probiotic agent; soil organic matter; Adaptation; Clean waters; Food security; Microbial ecosystem; Microbials; Nutrients cycling; Resilience; Sustainable agriculture; Water availability; Waters resources; adaptive management; alternative agriculture; climate change; food security; microbial community; water availability; water resource; Actinobacteria; aquatic environment; Article; biofilm; bioremediation; carbon cycling; climate change; cycling; denitrification; DNA replication; ecosystem; Escherichia coli; food insecurity; food security; fungal biomass; global change; greenhouse gas; human; marine environment; microbial community; microbiome; mitigation; nonhuman; protein expression; soil microflora; soil moisture; soil respiration; Stenotrophomonas maltophilia; temperature stress; water availability; water supply; water treatment | English | 2024 | 2024-11 | 10.1007/s11270-024-07533-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Quantifying Predictive Uncertainty and Feature Selection in River Bed Load Estimation: A Multi-Model Machine Learning Approach with Particle Swarm Optimization | This study presents a comprehensive multi-model machine learning (ML) approach to predict river bed load, addressing the challenge of quantifying predictive uncertainty in fluvial geomorphology. Six ML models-random forest (RF), categorical boosting (CAT), extra tree regression (ETR), gradient boosting machine (GBM), Bayesian regression model (BRM), and K-nearest neighbors (KNNs)-were thoroughly evaluated across several performance metrics like root mean square error (RMSE), and correlation coefficient (R). To enhance model training and optimize performance, particle swarm optimization (PSO) was employed for hyperparameter tuning across all the models, leveraging its capability to efficiently explore complex hyperparameter spaces. Our findings indicated that RF, GBM, CAT, and ETR demonstrate superior predictive performance (R score > 0.936), benefiting significantly from PSO. In contrast, BRM displayed lower performance (0.838), indicating challenges with Bayesian approaches. The feature importance analysis, including permutation feature and SHAP values, highlighted the non-linear interdependencies between the variables, with river discharge (Q), bed slope (S), and flow width (W) being the most influential. This study also examined the specific impact of individual variables on model performance by adding and excluding individual variables, which is particularly meaningful when choosing input variables for the model, especially in limited data conditions. Uncertainty quantification through Monte Carlo simulations highlighted the enhanced predictability and reliability of models with larger datasets. The correlation between increased training data and improved model precision was evident in the consistent rise in mean R scores and reduction in standard deviations as the sample size increased. This research underscored the potential of advanced ensemble methods and PSO to mitigate the limitations of single-predictor models and exploit collective model strengths, thereby improving the reliability of predictions in river bed load estimation. The insights from this study provide a valuable framework for future research directions focused on optimizing ensemble configurations for hydro-dynamic modeling. | Le, Xuan-Hien; Huynh, Trung Tin; Song, Mingeun; Lee, Giha | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, 2559 Gyeongsang, Sangju 37224, South Korea; Thuyloi Univ, Fac Water Resources Engn, 175 Tay Son, Hanoi 116705, Vietnam; Ho Chi Minh City Univ Technol, Bach Khoa Ho Chi Minh City Technol Joint Stock Co, VNU HCMC, Ho Chi Minh 70000, Vietnam | ; Le, Xuan-Hien/AAZ-9166-2021 | 57209735659; 57212469833; 59234060300; 35069799400 | hienlx@knu.ac.kr;tin.huynh@ises.vn;songmg9048@gmail.com;leegiha@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 14 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 1.98 | 2025-05-07 | 5 | 5 | ensemble techniques; feature sensitivity analysis; Monte Carlo simulation; particle swarm optimization (PSO); predictive uncertainty; river bed load estimation | SEDIMENT TRANSPORT; MODEL | ensemble techniques; feature sensitivity analysis; Monte Carlo simulation; particle swarm optimization (PSO); predictive uncertainty; river bed load estimation | Bayesian networks; Forestry; Intelligent systems; Mean square error; Monte Carlo methods; Nearest neighbor search; Particle size analysis; Particle swarm optimization (PSO); Regression analysis; Rivers; Swarm intelligence; Uncertainty analysis; Bed load; Ensemble techniques; Feature sensitivity; Feature sensitivity analyse; Load estimation; Monte Carlo's simulation; Particle swarm; Particle swarm optimization; Predictive uncertainty; River bed; River bed load estimation; Swarm optimization; Bayesian analysis; estimation method; machine learning; performance assessment; prediction; quantitative analysis; river bed; sensitivity analysis; uncertainty analysis; Sensitivity analysis | English | 2024 | 2024-07 | 10.3390/w16141945 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | ReQUSA: a novel ReRAM-based hardware accelerator architecture for high-speed quantum computer simulation | Quantum computers are currently regarded as an emerging computing technology that can solve problems more quickly than classical computers. However, since constructing a general quantum computer is technically difficult, quantum computer simulation has been used instead of real quantum computers. Simulating quantum computers on classical computers is challenging because the time and resources required for the vectormatrix multiplication (VMM) increase exponentially with the number of qubits. This paper proposes a new accelerator architecture called ReQUSA that leverages resistive random access memory (ReRAM) to accelerate the quantum computer simulation. The ReQUSA employs a ReRAM crossbar array structure, which is specialized for implementing the VMM, and a realized state method for reduced VMM operation. To the best of our knowledge, ReRAM-based accelerators for quantum computer simulators has not been previously reported. Here, we describe the hardware design of the architecture and compare the performances (hardware resource, simulation time, and accuracy) of our accelerator with those of current quantum computer simulators (QuEST, QPlayer, and Qiskit). On average, our proposed architecture reduced the simulation times by factors of x104 and x103 (x102) on average from those of QuEST and QPlayer (also Qiskit), respectively. In addition, our architecture achieved 99% accuracy in 16-bit fixed-point data representation. | Lee, Sanghyeon; Hour, Leanghok; Kim, Yongtae; Han, Youngsun | Pukyong Natl Univ, Dept Artificial Intelligence Convergence, Busan 48513, South Korea; Kyungpook Natl Univ, Dept Comp Sci & Engn, Daegu 41566, South Korea | 59951851100; 58817015100; 55699627900; 7404096461 | youngsun@pknu.ac.kr; | PHYSICA SCRIPTA | PHYS SCRIPTA | 0031-8949 | 1402-4896 | 99 | 3 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2024 | 2.6 | 35.5 | 0.5 | 2025-05-07 | 1 | 1 | ReQUSA; quantum computer simulation; resistive random access memory; vector-matrix multiplication | IN-MEMORY | quantum computer simulation; ReQUSA; resistive random access memory; vector-matrix multiplication | Memory architecture; Computer simulators; Hardware accelerator architecture; High Speed; Quanta computers; Quantum computer simulation; Random access memory; ReQUSA; Resistive random access memory; Simulation time; Vector-matrix multiplications; RRAM | English | 2024 | 2024-03-01 | 10.1088/1402-4896/ad2752 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Research Progress on Migratory Water Birds: Indicators of Heavy Metal Pollution in Inland Wetland Resources of Punjab, Pakistan | The heavy metal burden on natural freshwater ecosystems is uninterruptedly increasing, which could affect their biodiversity, particularly regarding avian species. Three river barrages were selected for the sampling of water birds from autumn 2021 to spring 2022. Seven heavy metals-nickel (Ni), copper (Cu), cobalt (Co), zinc (Zn), lead (Pb), cadmium (Cd), and manganese (Mn)-were estimated in the hearts and livers of Fulica atra (Common Coot), Anas strepera (Gad-wall), and Anas crecca (Eurasian Teal) (Linnaeus, 1758) by atomic absorption spectrometry. The mean concentrations of metals were found to be significantly (p g/g), and the lowest belonged to Cd (0.17 mu g/g). The concentrations of Zn, Cu, Pb, Cd, and Co were highest in A. strepera heart samples. However, the concentrations of Zn, Pb, Cd, and Mn were found to be highest in the livers of F. atra. A comparison between both tissues indicated that the concentration of Ni is significantly (p < 0.05) higher (except for F. atra from Trimmu barrage) in the livers of water birds and that the concentration of Cd is significantly higher in the hearts of water birds. The mean metal concentrations were higher than the background limits reported in various studies, suggesting that the wintering water birds of Pakistan are under a significant load of heavy metal pollution. Histopathological analysis suggested that the observed heavy metals altered the normal histologies of hearts and livers of Fulica atra (Common Coot), Anas strepera (Gadwall), and Anas crecca (Eurasian Teal) sampled from three wetlands of Punjab Pakistan. | Shaffique, Shifa; Kang, Sang-Mo; Ashraf, Muhammad Ahsan; Umar, Ali; Khan, Muhammad Saleem; Wajid, Muhammad; Al-Ghamdi, Abdullah Ahmed; Lee, In-Jung | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Univ Educ, Dept Zool, Div Sci & Technol, Lahore 54000, Pakistan; Univ Okara, Fac Life Sci, Dept Zool, Okara 56130, Pakistan; King Saud Univ, Coll Sci, Dept Bot & Microbiol, POB 2455, Riyadh 11451, Saudi Arabia | Khan, Muhammad Saleem/P-9208-2016; umar, ali/MZS-1566-2025; Kang, Sang-Mo/MBG-7823-2025; Lee, In-Jung/GLS-0432-2022; shaffique, shifa/KUC-7102-2024; Ashraf, Muhammad Ahsan/HTQ-5704-2023 | 57203898867; 56189696900; 58532473300; 57216041703; 56953801400; 15049111300; 35830345400; 16425830900 | shifa.2021@knu.ac.kr;ijlee@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 8 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0.5 | 2025-05-07 | 2 | 3 | atomic absorption spectrometry; heart; liver; water birds | DISTRICT JHANG; TISSUES; CONTAMINATION; TOXICITY; ZINC; LEAD; BIOAVAILABILITY; METHODOLOGIES; ACCUMULATION; DIVERSITY | atomic absorption spectrometry; heart; liver; water birds | Pakistan; Punjab [Pakistan]; Absorption spectroscopy; Atomic absorption spectrometry; Biodiversity; Birds; Histology; Tissue; Water absorption; Water pollution; Wetlands; Atomic-absorption spectrometry; Avian species; Copper cu; Freshwater ecosystem; Heavy metals pollution; Inland wetlands; Mean concentrations; Pakistan; Water birds; Wetland resources; cobalt; freshwater ecosystem; freshwater environment; river pollution; Heavy metals | English | 2024 | 2024-04 | 10.3390/w16081163 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Smart Contact Lens for Colorimetric Visualization of Glucose Levels in the Body Fluid | Frequent blood glucose monitoring is a crucial routine for diabetic patients. Traditional invasive methods can cause discomfort and pain and even pose a risk of infection. As a result, researchers have been exploring noninvasive techniques. However, a limited number of products have been developed for the market due to their high cost. In this study, we developed a low-cost, highly accessible, and noninvasive contact lens-based glucose monitoring system. We functionalized the surface of the contact lens with boronic acid, which has a strong but reversible binding affinity to glucose. To achieve facile conjugation of boronic acid, we utilized a functional coating layer called poly(tannic acid). The functionalized contact lens binds to glucose in body fluids (e.g., tear) and releases it when soaked in an enzymatic cocktail, allowing for the glucose level to be quantified through a colorimetric assay. Importantly, the transparency and oxygen permeability of the contact lens, which are crucial for practical use, were maintained after functionalization, and the lenses showed high biocompatibility. Based on the analysis of colorimetric data generated by the smartphone application and ultraviolet-visible (UV-vis) spectra, we believe that this contact lens has a high potential to be used as a smart diagnostic tool for monitoring and managing blood glucose levels. | Seo, Jeongin; Kang, Jumi; Kim, Jungwoo; Han, Hyeju; Park, Minok; Shin, Mikyung; Lee, Kyueui | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Korea Adv Inst Sci & Technol, Dept Chem, Daejeon 34141, South Korea; Sungkyunkwan Univ SKKU, Dept Intelligent Precis Healthcare Convergence, Suwon 16419, South Korea; Lawrence Berkeley Natl Lab LBNL, Energy Technol Area, Berkeley, CA 94720 USA; Inst Basic Sci IBS, Ctr Neurosci Imaging Res, Suwon 16419, South Korea; Sungkyunkwan Univ SKKU, Dept Biomed Engn, Suwon 16419, South Korea; Kyungpook Natl Univ, KNU Inst Basic Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU G LAMP Project Grp, Daegu 41566, South Korea; Kyungpook Natl Univ Hosp, Biomed Res Inst, Daegu 41940, South Korea | Lee, Kyueui/P-8152-2018; Shin, Mikyung/D-8483-2018; Lee, Kyueui/ACR-8902-2022 | 58917887400; 58003581400; 57211939526; 57561260500; 57212683444; 55973400500; 56404800600 | mikyungshin@g.skku.edu;kyueui@knu.ac.kr; | ACS BIOMATERIALS SCIENCE & ENGINEERING | ACS BIOMATER SCI ENG | 2373-9878 | 10 | 6 | SCIE | MATERIALS SCIENCE, BIOMATERIALS | 2024 | 5.5 | 35.5 | 1.21 | 2025-05-07 | 5 | 5 | polytannic acid; glucose sensing; contact lens; colorimetric sensing | SURFACE-CHEMISTRY; POLYDOPAMINE; BIOSENSOR | colorimetric sensing; contact lens; glucose sensing; polytannic acid | Blood Glucose; Blood Glucose Self-Monitoring; Body Fluids; Boronic Acids; Colorimetry; Contact Lenses; Glucose; Humans; Smartphone; Tears; Binding energy; Biocompatibility; Blood; Color; Colorimetry; Diagnosis; Glucose; glucose; oxygen; tannin; boronic acid derivative; glucose; Blood glucose monitoring; Boronic acid; Colorimetric sensing; Diabetics patients; Functionalized; Glucose level; Glucose sensing; Invasive methods; Noninvasive technique; Polytannic acid; Article; binding affinity; biocompatibility; blood glucose monitoring; body fluid; cell viability; colorimetry; conjugation; contact angle; controlled study; cytotoxicity; glucose assay; glucose blood level; glucose level; human; non invasive procedure; surface analysis; ultraviolet radiation; water content; X ray photoemission spectroscopy; body fluid; chemistry; contact lens; devices; lacrimal fluid; metabolism; procedures; self-monitoring blood glucose; smartphone; Contact lenses | English | 2024 | 2024-05-23 | 10.1021/acsbiomaterials.4c00431 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Spatiotemporal Dynamics of Suspended Particulate Matter in Water Environments: A Review | Suspended particulate matter (SPM) is an indispensable component of water environments. Its fate and transport involve various physical and biogeochemical cycles. This paper provides a comprehensive review of SPM dynamics by integrating insights from biogeochemical processes, spatiotemporal observation techniques, and numerical modeling approaches. It also explores methods for diagnosing SPM-mediated biogeochemical processes, such as the flocculation kinetics test and organic matter composition analysis. Advances in remote sensing, in situ monitoring, and high-resolution retrieval algorithms are discussed, highlighting their significance in detecting and quantifying SPM concentrations across varying spatial and temporal scales. Furthermore, this review examines integrated models that incorporate population balance equations on the basis of flocculation kinetics into multi-dimensional sediment transport models. The results from this study provide valuable insights into SPM dynamics, ultimately enhancing our knowledge of SPM behavior and transport in water environments. However, uncertainties remain due to limited field data on flocculation kinetics and the need for parameter optimization in numerical models. Addressing these gaps through enhanced fieldwork and model refinement will significantly improve our ability to predict and manage SPM dynamics, which is critical for sustainable aquatic ecosystem management in an era of rapid environmental change. | Huynh, Trung Tin; Kim, Jaein; Lee, Sang Deuk; Fettweis, Michael; Bi, Qilong; Kim, Sangsik; Lee, Sungyun; Choi, Yun Young; Nguyen, Huu Son; Bui, Trong Vinh; Lee, Byung Joon | Ho Chi Minh City Univ Technol HCMUT, VNU HCM, Bach Khoa Ho Chi Minh City Sci Technol Joint Stock, Ho Chi Minh City 70000, Vietnam; Kyungpook Natl Univ KNU, Sch Adv Sci & Technol Convergence, 2559 Gyeongsang Daero, Sangju 37224, South Korea; Kyungpook Natl Univ, Energy Environm Inst, 2559 Gyeongsang Daero, Sangju 37224, Gyeongbuk, South Korea; Nakdonggang Natl Inst Biol Resources NNIBR, Sangju 37242, South Korea; Royal Belgian Inst Nat Sci, Operat Directorate Nat Environm, Rue Vautier 29, B-1000 Brussels, Belgium; Deltares, Dept Ecosyst & Sediment Dynam, NL-2629 HV Delft, Netherlands; Kyungpook Natl Univ KNU, Dept Energy Chem Engn, 2559 Gyeongsang daero, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Environm & Safety Engn, 2559 Gyeongsang Daero, Sangju 37224, South Korea; Ho Chi Minh City Univ Technol HCMUT, Fac Geol & Petr Engn, VNU HCM, Ho Chi Minh City 70000, Vietnam | ; kim, sangsik/ACL-0965-2022 | 57212469833; 57194534599; 55983604500; 6603404718; 56542803900; 56158171800; 36438267000; 56019880500; 59099134500; 56828835200; 56016052400 | httinvn@gmail.com;jikim1224@knu.ac.kr;diatom83@nnibr.re.kr;mfettweis@naturalsciences.be;qilong.bi@deltares.nl;sangsik@knu.ac.kr;sungyunlee@knu.ac.kr;yunchoi@knu.ac.kr;nguyenhuuson@hcmut.edu.vn;btvinh@hcmut.edu.vn;bjlee@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 24 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 0 | 2025-05-07 | 0 | 0 | suspended particulate matter; remote sensing; echosounder; population balance equation model; suspended particulate matter retrieval | REMOTE-SENSING REFLECTANCE; NEURAL-NETWORK; SIZE DISTRIBUTIONS; FLOCCULATION MODEL; SEDIMENT PROCESSES; OPTICAL-PROPERTIES; MIXED SEDIMENT; CLIMATE-CHANGE; ECHO-SOUNDER; TRANSPORT | echosounder; population balance equation model; remote sensing; suspended particulate matter; suspended particulate matter retrieval | Abiotic; Aquatic ecosystems; Biotic; Digital elevation model; Sediment transport; Suspended sediments; Biogeochemical process; Echo sounders; Flocculation kinetics; Matter dynamics; Population balance equation models; Remote-sensing; Suspended particulate matter retrieval; Suspended particulate matters; Water environments; dynamic analysis; ecosystem management; environmental change; flocculation; optimization; remote sensing; sediment transport; spatiotemporal analysis; suspended particulate matter; Flocculation | English | 2024 | 2024-12 | 10.3390/w16243613 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Sustainable Solutions for Mitigating Water Scarcity in Developing Countries: A Comprehensive Review of Innovative Rainwater Storage Systems | As global water resources decline and demand increases due to population growth and climate change, innovative rainwater storage systems (IRSSs) have become crucial. This review examines the potential of IRSSs to sustainably address rainwater challenges by analyzing key factors that influence their success. Drawing on research from Scopus and Google Scholar, it evaluates IRSSs in both urban and rural settings across different countries and regions, focusing on their contribution to Sustainable Development Goal (SDG) 6. This review highlights how social, environmental, economic, and policy factors affect the success of IRSS compared to traditional systems common in developing nations. IRSSs can outperform traditional methods in sustainability, encouraging their adoption. However, there is a significant gap in policy integration that needs to be addressed for successful implementation. Further research is needed to better understand the contributing factors and their role in achieving sustainability. Integrating rainwater harvesting into national water policies could offer valuable guidance for policymakers and water resource managers in addressing issues like urban floods, water scarcity, and related social and environmental challenges in developing countries. | Ssekyanzi, Geoffrey; Ahmad, Mirza Junaid; Choi, Kyung-Sook | Kyungpook Natl Univ, Dept Food Secur & Agr Dev, Daegu 41566, South Korea; Dept Prod, POB 21, Kyotera, Uganda; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | ; Ahmad, Mirza/AAD-5982-2020 | 59326631600; 57201479907; 54392662900 | sskyanzigeoffrey11@gmail.com;agri.junaid1205@gmail.com;ks.choi@knu.ac.kr; | WATER | WATER-SUI | 2073-4441 | 16 | 17 | SCIE | ENVIRONMENTAL SCIENCES;WATER RESOURCES | 2024 | 3 | 35.5 | 1.54 | 2025-05-07 | 11 | 13 | water security; innovative rainwater harvesting systems; policy regulations; sustainability factors; climate resilience | CHALLENGES; WORLD | climate resilience; innovative rainwater harvesting systems; policy regulations; sustainability factors; water security | Climate resilience; Global water resources; Innovative rainwater harvesting system; Policy regulations; Rainwater harvesting system; Storage systems; Sustainability factor; Sustainable solution; Water scarcity; Water security; developing world; flood; harvesting; population growth; rainwater; Sustainable Development Goal; water management; water resource; Sustainable development goals | English | 2024 | 2024-09 | 10.3390/w16172394 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Application of biosolid for berseem clover fertilization: Fodder characteristics and health risk assessment | Finding sustainable methods for utilizing biosolids, also known as municipal sewage sludge (SS), presents a pressing challenge in modern waste management practices. Therefore, this study aimed to evaluate the impact of SS amendment on growth, biochemical, proximate, and heavy metal bioaccumulation parameters of berseem clover (Trifolium alexandrinum L.) fodder crop under field conditions. Trifolium alexandrinum was cultivated using different rates of SS mixing (i.e., T0: 0% as control with no SS application, T1: 5%, and T2: 10%). The results obtained showed a significant (p < 0.05) increment in growth, biochemical, and proximate parameters of T. alexandrinum with an increasing SS mixing rate. The highest productivity of T. alexandrinum fodder (1.92 kg m(-2) fw) was observed in the T2 treatment as compared to the control treatment. The heavy metal analysis of shoot and root parts of T. alexandrinum showed that the contents (mg kg-1) of eight elements (Cd 0.02-0.13, Co 0.04-0.08, Cu 5.94-0.05, Cr 0.43-1.68, Fe 7.08-15.93, Ni 0.89-2.90, Mn 1.62-5.38, and Zn 3.30-7.04) increased significantly (p < 0.05) with SS mixing rate. The bioaccumulation factor (BAF) was below 1 except for Cu and Zn exhibiting their rapid uptake by plants from SS-treated soils. However, dietary intake modeling (DIM < 1) and health risk index (HRI < 1) studies showed that the levels of heavy metals did not exceed the permissible limits in any SS treatment. Overall, SS amendment has a positive impact on the growth, biochemical, proximate, and heavy metal characteristics of T. alexandrinum. Therefore, this study suggested a strategy for low-cost soil fertilization and fodder crop production which could sustainably benefit waste recycling. | Siric, Ivan; Alhag, Sadeq K.; Al-Shahari, Eman A.; Andabaka, Zeljko; Kumar, Pankaj; Fayssal, Sami Abou; Adelodun, Bashir; Eid, Ebrahem M. | Univ Zagreb, Fac Agr, Svetosimunska 25, Zagreb 10000, Croatia; King Khalid Univ, Coll Sci & Arts, Biol Dept, Muhayl Asser 61913, Saudi Arabia; Gurukula Kangri Univ, Dept Zool & Environm Sci, Hardwar 249404, India; Soc Agroenvironm Sustainabil, Res & Dev Div, Dehra Dun 248007, India; Univ Forestry, Fac Agron, Dept Agron, Sofia 1797, Bulgaria; Lebanese Univ, Fac Agr, Dept Plant Prod, Beirut 1302, Lebanon; Univ Ilorin, Dept Agr & Biosyst Engn, Ilorin 240103, Nigeria; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Kafrelsheikh Univ, Fac Sci, Bot Dept, Kafr Al Sheikh 33516, Egypt | Eid, Ebrahem/O-2723-2013; Kumar, Pankaj/AAF-2231-2019; Alhag, Sadeq/GRJ-2635-2022; Adelodun, Bashir/O-2941-2018; kumar, Pankaj/HPF-8395-2023; Abou Fayssal, Sami/ABF-6226-2020 | 55233815400; 23093197200; 57218120186; 55934838700; 57281192700; 57218598581; 57193774482; 35794350700 | kumarpankajgkv@gmail.com; | CHILEAN JOURNAL OF AGRICULTURAL RESEARCH | CHIL J AGR RES | 0718-5839 | 84 | 3 | SCIE | AGRICULTURE, MULTIDISCIPLINARY;AGRONOMY | 2024 | 1.8 | 35.6 | 0 | 2025-05-07 | 0 | 0 | Bioaccumulation; health risk studies; sewage sludge; soil fertilization; waste management | SEWAGE-SLUDGE; RED-CLOVER | Bioaccumulation; health risk studies; sewage sludge; soil fertilization; waste management | English | 2024 | 2024 (MAY-JUN) | 10.4067/s0718-58392024000300349 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Bending strain-induced changes in perpendicular magnetic properties of Pt/Co/Pt films on flexible substrates | We studied the irreversible changes in the perpendicular magnetic properties of Pt(2.2 nm)/Co(0.8 nm)/Pt(2.2 nm) films deposited on a flexible polyethylene terephthalate substrate with bending deformation. The changes in the magnetic properties of the Pt/Co/Pt film with deformation were analyzed using magneto-optical Kerr-effect microscopy. The film was bent in one direction using cylindrical rods or semicylindrical grooves of different radii and then restored to the initial flat state. No significant changes in the magnetic properties due to bending strain were observed below a critical bending curvature. However, for bending curvatures above +0.25 mm(-1) or below -0.14 mm(-1), the magnetic domain shape changed from circular to elongated ellipses, perpendicular to the bending direction, and the coercivity of the film increased by 10%-30%. Furthermore, the domain wall motion exhibited a distinct anisotropic behavior, with similar to 12-fold difference in the velocity of domain wall motion in different directions. Conclusively, the magnetic properties of the Pt/Co/Pt film fabricated on a flexible substrate exhibited irreversible changes beyond a critical deformation of +2.44% or -1.37%. | Kim, Jeongjun; Dho, Joonghoe | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | 57930877100; 6602898623 | jhdho@knu.ac.kr; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 124 | 10 | SCIE | PHYSICS, APPLIED | 2024 | 3.6 | 35.6 | 2.28 | 2025-05-07 | 3 | 4 | THIN-FILM; ANISOTROPY | Bending (deformation); Domain walls; Magnetic domains; Optical Kerr effect; Plastic bottles; Substrates; Bending curvature; Bending strain; Cylindrical rod; Domain wall motion; Flexible substrate; Irreversible changes; Magneto-optical Kerr effects; Optical Kerr effect microscopy; Pt films; Strain-induced change; Magnetic properties | English | 2024 | 2024-03-04 | 10.1063/5.0198200 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Configurable anti-ambipolar photoresponses for optoelectronic multi-valued logic gates | Anti-ambipolar transistors (AATs) are the leading platform for the paradigm shift from binary to multi-valued logic (MVL) circuits, increasing circuit integration density and data processing capacity. However, most AATs with p-n heterojunctions present limited controllability of the transconductance peak, which is key to MVL operation. Here, we report optically configurable AAT/bi-AAT photoresponses implemented with an InSe field-effect transistor for potential MVL operations. The charge trapping and detrapping processes incorporated with manually introduced trap states form the AAT peaks. Furthermore, leveraging a symmetric device configuration, the dark current is significantly suppressed, and AAT photoresponses are highlighted. Contributed by two pathways of trap states, the AAT/bi-AAT photoresponses are switchable by incident optical wavelength. This dependence facilitates optical wavelength to be one of the logic inputs for MVL, based on which we propose circuit-free ternary logic gates in a single device that can achieve more than similar to 6 and similar to 19 times improved data density (1 bit per transistor) for NMAX and XNOR, compared with such circuits in a traditional binary design. This work realizes optically controlled AAT photoresponses, paving the way to exploit optical wavelength as a new degree of freedom in MVL computing, offering a route toward ultra-high-density, ultra-low-power, and optically programmable optoelectronic integrated circuits. | Cui, Xiaoqi; Kim, Sunmean; Ahmed, Faisal; Du, Mingde; Liapis, Andreas C.; Munoz, Juan Arias; Shafi, Abde Mayeen; Uddin, Md Gius; Ali, Fida; Zhang, Yi; Kang, Dong-Ho; Lipsanen, Harri; Kang, Seokhyeong; Yoon, Hoon Hahn; Sun, Zhipei | Aalto Univ, QTF Ctr Excellence, Dept Elect & Nanoengn, Espoo 02150, Finland; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Sch Elect Engn & Comp Sci, Dept Semicond Engn, Gwangju 61005, South Korea; Pohang Univ Sci & Technol, Dept Elect Engn, Pohang 37673, South Korea | ; Zhang, Yi/AAG-7916-2021; Kang, Dong-Ho/AAN-3725-2021; Ali, Fida/JNE-5322-2023; Cui, Xiaoqi/IXD-2005-2023; Sun, Zhipei/G-2442-2013; Du, Mingde/AAE-1482-2021; Lipsanen, Harri/C-4336-2013; Yoon, Hoon Hahn/X-8475-2019; Lee, Sung-Yun/JDM-2887-2023 | 57303944400; 57193135112; 56645768800; 56417088700; 35189067900; 58657302000; 57188995268; 57226604706; 57203619132; 57225166573; 56278168800; 8229418700; 35848454700; 59654784500; 24587999700 | hoonhahnyoon@gist.ac.kr;zhipei.sun@aalto.fi; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 125 | 5 | SCIE | PHYSICS, APPLIED | 2024 | 3.6 | 35.6 | 0.57 | 2025-05-07 | 1 | 1 | WAALS; DEVICE; DIODES | Computer circuits; Data handling; Degrees of freedom (mechanics); Field effect transistors; Heterojunctions; Low power electronics; Many valued logics; Ambipolar; Ambipolar transistors; Circuit integration; Logic operations; Multi-valued; Multi-valued logic circuits; Optical wavelength; Paradigm shifts; Photoresponses; Trap state; Logic gates | English | 2024 | 2024-07-29 | 10.1063/5.0218591 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
