| ○ | Article | Comparative distribution and population genetics of bisexual and parthenogenetic Asian longhorned tick (Haemaphysalis longicornis) in the Republic of Korea | The Asian longhorned tick (Haemaphysalis longicornis) is an ectoparasite that transmits several pathogens, including severe fever with thrombocytopenia syndrome virus, to humans and animals. Wild populations of H. longicornis are maintained by both bisexual and asexual reproductive strategies. This study examined the geographical distribution and genetic differentiation of bisexual and parthenogenetic H. longicornis populations collected from 12 cities across the Republic of Korea: Chuncheon (CC), Sokcho (SC), Samcheok (SCH), Ganghwa (GH), Sangju (SJ), Ulsan (US), Jinju (JNJ), Boryeong (BR), Gochang (GC), Jindo (JD), Jeju (JJ), and Seogwipo (SG). Based on 16S ribosomal DNA sequence analysis, parthenogenetic and bisexual individuals were found to coexist at varying proportions depending on the region. Parthenogenetic individuals were more dominant in the northeastern regions (CC, US, SJ, SC, GH, and SCH), while bisexual individuals were more abundant in the southwestern regions (SG, BR, JD, JJ, GC, and JNJ). Population genetic analysis based on concatenated mitochondrial cytochrome c oxidase subunit I (COI) and cytochrome B (CytB) genes revealed that the genetic structure of female ticks was primarily influenced by their reproductive strategy (bisexual or parthenogenetic), rather than by geographic origin. Demographic analysis detected evidence of population expansion in both northeastern (CC, SC, and SCH) and southwestern (JD and SG) regions. These findings enhance the understanding of H. longicornis population dynamics in the Republic of Korea. © 2025 The Author(s) | Kim, Jiseok; Kim, Donghun | Department of Vector Entomology, Kyungpook National University, Sangju, South Korea; Department of Vector Entomology, Kyungpook National University, Sangju, South Korea, Research Institute of Invertebrate Vector, Kyungpook National University, Sangju, South Korea | 57870544800; 56115927500 | dklome2018@knu.ac.kr; | Ticks and Tick-borne Diseases | TICKS TICK-BORNE DIS | 1877-959X | 1877-9603 | 16 | 4 | SCIE | INFECTIOUS DISEASES;MICROBIOLOGY;PARASITOLOGY | 2024 | 3.4 | 11.7 | 0 | bisexual tick; Haemaphysalis longicornis; parthenogenetic tick; population genetics; reproductive lineage | cytochrome b; cytochrome c oxidase; DNA 16S; Article; bisexuality; demography; DNA sequence; female; gene structure; genetic analysis; genetic variability; geographic distribution; Haemaphysalis longicornis; molecular phylogeny; nonhuman; parthenogenesis; polymerase chain reaction; population dynamics; population genetics; population growth; reproduction; sequence analysis; South Korea; species distribution; species dominance | English | Final | 2025 | 10.1016/j.ttbdis.2025.102507 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Insecticide resistance mutations of Anopheles species in the Republic of Korea | The number of reported malaria cases transmitted by Anopheles mosquitoes in the Republic of Korea (ROK) increased from 420 in 2022 to 746 in 2023, a 77.6% increase. Eight Anopheles species are currently reported in the ROK, including six species belonging to the Anopheles Hyrcanus Group and one species each belonging to the Barbirostris Group and Lindesayi Group. However, studies on insecticide resistance in the ROK has predominantly concentrated on Anopheles sinensis or more broadly, members of the Hyrcanus Group. Reported differences in vector competence and ecological characteristics of mosquito species in the ROK highlight the importance for conducting accurate evaluations of insecticide resistance for each of the Anopheles species for informing the potential efficacy of vector control to reduce malaria transmission. All eight species of Anopheles mosquitoes were collected in/near the demilitarized zone (DMZ), a malaria high-risk region in the ROK. Additional specimens were collected in Seoul [Yongsan US Army Garrison (USAG)] and Pyeongtaek (Humphreys USAG) where malaria risks are much lower. Anopheles mosquitoes were identified to species using a multiplex PCR method and then evaluated for the presence of acetylcholinesterase-1 (ace-1) and voltage-gated sodium channel (vgsc) regions to identify mutations linked to insecticide resistance. Analysis of the ace-1 region identified insecticide resistance alleles in four species of the Hyrcanus Group (An. sinensis, An. kleini, An. belenrae, and An. pullus), while ace-1 resistance alleles were not observed in the other four species. The screening of the vgsc gene fragment confirmed the presence of resistant alleles only in An. sinensis (considered a poor malaria vector) and An. kleini (a primary malaria vector) in the ROK. This study represents a preliminary investigation of insecticide resistance mutations across all Anopheles species in the ROK. These findings are crucial in advancing mosquito control strategies to mitigate future malaria infections. | Jeon, Jiseung; Kim, Heung Chul; Klein, Terry A.; Jun, Hojong; Choi, Kwang Shik | Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu, South Korea; U Inc, Daesakwan ro 34 gil, Seoul, South Korea; Med Dept Act Korea 65th Med Brigade, Unit 15281, Force Hlth Protect & Prevent Med, Pyeongtaek, South Korea; Kangwon Natl Univ, Sch Med, Dept Med Environm Biol & Trop Med, Chunchon, South Korea | ; Jeon, Jiseung/NRB-6964-2025 | 58673027200; 8847173600; 7202313728; 57193604361; 36602283400 | ksc@knu.ac.kr; | PLOS NEGLECTED TROPICAL DISEASES | PLOS NEGLECT TROP D | 1935-2735 | 19 | 1 | SCIE | PARASITOLOGY;TROPICAL MEDICINE | 2024 | 3.4 | 11.7 | 6.71 | 2025-05-07 | 0 | 1 | TIME PCR AMPLIFICATION; VIVAX MALARIA; FREQUENCY DETECTION; VECTOR COMPETENCE; SINENSIS DIPTERA; HYRCANUS GROUP; MOSQUITO; POPULATIONS; CULICIDAE; ACETYLCHOLINESTERASE | Animals; Anopheles; Female; Insecticide Resistance; Insecticides; Malaria; Mosquito Vectors; Mutation; Republic of Korea; acetylcholinesterase; genomic DNA; insecticide; voltage gated sodium channel; insecticide; allele; Anopheles; Anopheles sinensis; Article; controlled study; DNA extraction; DNA sequencing; gene duplication; gene frequency; genetic variation; government; human; insecticide resistance; malaria; mosquito control; multiplex polymerase chain reaction; mutation; mutational analysis; nonhuman; nucleotide sequence; phylogeny; polymerase chain reaction; prevalence; Sanger sequencing; sequence analysis; South Korea; species composition; species identification; animal; drug effect; female; genetics; malaria; mosquito vector; prevention and control | English | 2025 | 2025-01 | 10.1371/journal.pntd.0012748 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Microgels: from synthesis to tissue regeneration applications | Microgels have emerged as a versatile platform in tissue engineering and regenerative medicine, offering unique physicochemical properties, modularity, and the ability to mimic native extracellular matrix microenvironments. Derived from natural or synthetic hydrogels, microgels exhibit biocompatibility, controllability, and injectability, which make them suitable for diverse tissue engineering applications. This review systematically explores the fabrication methods of microgels and highlights their role in cell encapsulation, therapeutic delivery, and structural tissue development. Advanced strategies in microgel manufacturing, such as injectable hydrogels, assembled microgel platforms, and in-gel assemblies, have enabled the creation of highly customizable and functional tissue constructs. Additionally, three-dimensional bioprinting of microgels provides a high-throughput strategy to generate patient-specific scaffolds with precise spatial organization and enhanced cellular viability. It is expected that more efficient and cost-effective strategies for mass production and customization of microgel systems to specific cell types or patient needs are essential for future studies. The innovations, including stimuli-responsive and four-dimensional microgels, will expand their potential by enabling dynamic in situ tunable microenvironments. These advancements will enable optimal design, scalability, and integration into therapeutic applications, thereby accelerating the clinical translation of microgel-based therapies and driving the development of multifunctional tissue products. | Hann, Sung Yun; Kang, Yunsung; Cui, Haitao; Zhang, Lijie Grace | Kyungpook Natl Univ, Dept Precis Mech Engn, Sangju 37224, South Korea; Kyungpook Natl Univ, Sch Adv Sci & Technol Convergence, Sangju 37224, South Korea; Kyungpook Natl Univ, Convergence Res Ctr Mech & Chem Engn CRCMCE, Sangju 37224, South Korea; Chongqing Univ, Dept Bioengn, Chongqing 400044, Peoples R China; Chongqing Univ, Key Lab Biorheol Sci & Technol, Minist Educ, Chongqing 400045, Peoples R China; George Washington Univ, Dept Mech & Aerosp Engn, Washington, DC 20052 USA | Hann, Sung Yun/HZM-2708-2023 | 57207825277; 57193683552; 55587316100; 59698279400 | syhann@knu.ac.kr; htcui.cbe@cqu.edu.cn; | BIOFABRICATION | BIOFABRICATION | 1758-5082 | 1758-5090 | 17 | 3 | SCIE | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS | 2024 | 8 | 11.7 | 0 | 0 | cell encapsulation; injectable hydrogels; assembly; 3D bioprinting; tissue regeneration | CROSS-LINKING; CARDIAC CONSTRUCT; PHASE-BEHAVIOR; CELL DELIVERY; IN-VITRO; HYDROGEL; FABRICATION; PARTICLES; ADHESION; MATRIX | 3D bioprinting; assembly; cell encapsulation; injectable hydrogels; tissue regeneration | Animals; Biocompatible Materials; Bioprinting; Humans; Hydrogels; Microgels; Regeneration; Regenerative Medicine; Tissue Engineering; Tissue Scaffolds; Biocompatibility; Clinical research; Cost effectiveness; Gels; Hydrogels; Microgels; Physicochemical properties; Product design; Scaffolds (biology); Throughput; Tissue; biomaterial; hydrogel; microgel (material); Bioprinting; Cell encapsulations; Injectability; Injectable hydrogels; Microenvironments; Microgel; Native extracellular matrix; Physicochemical property; Regenerative medicine; Tissues engineerings; animal; bioprinting; chemistry; human; procedures; regeneration; regenerative medicine; tissue engineering; tissue scaffold; Assembly; Tissue regeneration | English | 2025 | 2025-07-01 | 10.1088/1758-5090/addde9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | New Numerical Approach to Determine the Optimum Mixing Ratio of Electrode Materials for Maximum Li-ion Battery Performance by the Hierarchical Homogenization and Feedforward Neural Networks | The effective electrical conductivity (EEC) and capacity of the electrodes are altered by the composition of electrode materials, leading to a significant impact on the performance of the Li-ion battery (LIB) cells. This study aims to develop a more efficient numerical optimization method that integrates hierarchical homogenization and feedforward neural networks (FNN) to identify the optimal composition of electrode materials. Currently, this determination heavily relies on conducting multiple experiments. The cathode's EEC, as per its formulation, is assessed through hierarchical homogenization of its components. The optimization is expedited using FNN in the homogenization. The LIB cell's performance is evaluated based on the cathode formulation via the hierarchical homogenization and the Doyle/Fuller/Newman model. The multi-objective optimization problem is formulated and solved using the modified NSGA-II. The resulting Pareto-optimal solutions identify the power optimized and energy optimized cells. The power density of the former is increased by 51% while maintaining the same energy density and the latter cell's energy density is increased by 68% while maintaining the same power density, as compared to the initial cell. | Seo, Boil; Kim, Cheol | Kyungpook Natl Univ, Dept Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | 59124092200; 55508786300 | kimchul@knu.ac.kr; | INTERNATIONAL JOURNAL OF PRECISION ENGINEERING AND MANUFACTURING-GREEN TECHNOLOGY | INT J PR ENG MAN-GT | 2288-6206 | 2198-0810 | 12 | 1 | SCIE | ENGINEERING, MANUFACTURING;ENGINEERING, MECHANICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2024 | 5.6 | 11.8 | 2.3 | 2025-05-07 | 1 | 1 | Lithium-ion Batteries; Cathode Composition; Hierarchical Homogenization; Feedforward Neural networks; Multi-objective Optimization | REPRESENTATIVE VOLUME ELEMENTS; RANDOM FIBER DISTRIBUTIONS; ELECTRICAL-CONDUCTIVITY; ACTIVE MATERIAL; OPTIMAL-DESIGN; LITHIUM; OPTIMIZATION; BINDER; COMPOSITES; MODELS | Cathode Composition; Feedforward Neural networks; Hierarchical Homogenization; Lithium-ion Batteries; Multi-objective Optimization | Cathodes; Feedforward neural networks; Homogenization method; Ions; Multiobjective optimization; Numerical methods; Pareto principle; Battery cells; Cathode composition; Electrical conductivity; Electrode material; Energy density; Hierarchical homogenization; Mixing ratios; Multi-objectives optimization; Numerical approaches; Power densities; Lithium-ion batteries | English | 2025 | 2025-01 | 10.1007/s40684-024-00628-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Pure Mechanical Impact Trimming for Ultra High-strength Steels: A Strain Rate-managed Approach to Enhance Shear Edge Quality Without Thermal Effects | Mechanical trimming is preferred in industrial applications due to its energy efficiency and high productivity compared to laser trimming. However, ultra high-strength steel (UHSS) for lightweight structures exhibits poor shear quality and is prone to material damage during mechanical trimming. Heat-assisted mechanical trimming can be employed for UHSS to address this issue; however, it has drawbacks, including high energy consumption and thermal damage to the material. Recently, an ultra high-speed trimming (UHST) method was introduced for UHSS to mitigate thermal damage. This technology achieves high-quality shear edges by converting the high kinetic energy of the tool into localized thermal energy in a narrow adiabatic shear band (approximately 800 °C in the adiabatic band) at very high cutting speeds (exceeding 10 m/s). However, equipment capable of operating at speeds exceeding 10 m/s requires significant capital investment, consumes considerable energy, and retains the thermal effects within the adiabatic band. This study introduces a purely mechanical impact trimming technique that manages the strain-rate effect to improve shear edge quality while reducing material damage. The central concept is to perform trimming at a speed that is sufficiently high to reduce the fracture strain of the material but considerably lower than the speed at which adiabatic heating occurs. In this method, thermal damage is avoided, and a lower fracture strain helps minimize material damage during the cutting process. This approach, termed intermediate-speed impact trimming (IST) in this work, is a purely mechanical impact trimming method, which avoids thermal effects. Experimental and numerical investigations of the proposed method were conducted using UHSS sheets (CP1180-1.4t and MS1480-1.5t). In order to apply this approach to trimming, fracture limit experiments with varying strain rates were conducted to determine the trimming tool speed that reduces the fracture strain; subsequently, the IST tests were conducted with different clearances (5%, 10%, and 15%) and impact trimming speeds (1.1 and 2.0 m/s). The experimental results indicate that the shear edge produced by the IST exhibits a uniform shape and minimal variation in hardness, suggesting that this method reduces damage to the shear edge. Microstructural analysis revealed that the shear edge was formed by pure mechanical deformation. To analyze the trimming mechanism, a rate-dependent fracture model was developed to capture the material test results. This model was implemented in a Vectorized User Material (VUMAT) subroutine of the ABAQUS software to simulate the trimming process and successfully replicate the shear edge observed in the experimental results. Furthermore, the application of the proposed method to a door-impact beam was explored. Both the experimental and analytical results confirmed that the IST method reduces material damage and produces a high-quality shear edge devoid of thermal effects. © The Author(s) 2025. | Lim, Jae-Hyuk; Lee, Seok-Won; Lee, Jaewook; Park, Chan Hoon; Lee, Eun-Ho | Department of Mechanical Engineering, Sungkyunkwan University, Suwon-Si, 16419, South Korea; Department of Mechanical Engineering, Sungkyunkwan University, Suwon-Si, 16419, South Korea; Department of Smart Mobility Engineering, Kyungpook National University, Daegu-Si, 41566, South Korea; Lingtweight Materials Research Team, Hyundai Motors Company, Uiwang-Si, 16082, South Korea; Department of Mechanical Engineering, Sungkyunkwan University, Suwon-Si, 16419, South Korea, Department of Smart Fabrication Technology, Sungkyunkwan University, Suwon-Si, 16419, South Korea, Department of Intelligent Robotics, Sungkyunkwan University, Gyeonggi-Do, Suwon, 16419, South Korea | 59640410300; 59447836000; 57203144566; 59723659700; 55973407800 | e.h.lee@skku.edu; | International Journal of Precision Engineering and Manufacturing - Green Technology | INT J PR ENG MAN-GT | 2288-6206 | 2198-0810 | SCIE | ENGINEERING, MANUFACTURING;ENGINEERING, MECHANICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2024 | 5.6 | 11.8 | 0 | 2025-05-07 | 0 | Fracture model; Mechanical impact trimming; Numerical analysis; Shear edge; Ultra-high-strength steel | Cooling towers; Cutting tools; Fracture energy; Light velocity; Rockwell hardness; Shear flow; Trimming; Voltage dividers; Energy; Fracture model; Materials damage; Mechanical; Mechanical impact trimming; Mechanical impacts; Shear edge; Speed impacts; Thermal; Ultra-high-strength steels; Strain rate | English | Article in press | 2025 | 10.1007/s40684-025-00720-5 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Adjustable Virtual Impedance via Anti-windup Method for Enhancing Transient Stability and Grid-Forming Capability Under Current Limiting Conditions | This letter presents a novel method to enhance the transient stability and grid forming (GFM) capability under current limiting conditions. The proposed method employs dual-loop vector voltage control with a back-calculation anti-windup strategy, using adjustable gain to modify the reactance-to-resistance ratio of the equivalent virtual impedance. The method ensures seamless operation during transitions between normal and abnormal grid conditions while significantly improving transient stability and GFM capability. Theoretical analysis has been validated through 2-kVA-scale experiments, demonstrating the effectiveness of the proposed method. | Kim, Seongyeon; Kim, Ki-Hyun; Cui, Shenghui; Jung, Jae-Jung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Seoul Natl Univ, Dept Elect & Comp Engn, Seoul 08826, South Korea; Seoul Natl Univ, SNU Elect Power Res Inst, Seoul 08826, South Korea | 59469608100; 59194094800; 56157479900; 55368433400 | jarrymark@knu.ac.kr; rlarlgus5615@knu.ac.kr; cuish@snu.ac.kr; jj.jung@knu.ac.kr; | IEEE TRANSACTIONS ON POWER ELECTRONICS | IEEE T POWER ELECTR | 0885-8993 | 1941-0107 | 40 | 5 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 6.5 | 11.9 | 0 | 2025-05-07 | 0 | 0 | Impedance; Power system stability; Grid forming; Voltage control; Limiting; Transient analysis; Circuit stability; Current limiters; Circuit faults; Stability criteria; Anti-windup; current limitation; grid forming (GFM); transient stability; virtual impedance | Anti-windup; current limitation; grid forming (GFM); transient stability; virtual impedance | Electromagnetic transients; Transients; Vector control (Electric machinery); Windmill; Anti-windup; Anti-windup strategy; Backcalculations; Current limitation; Current limiting; Dual loops; Grid forming; Limiting condition; Novel methods; Virtual impedance; Transient stability | English | 2025 | 2025-05 | 10.1109/tpel.2025.3525649 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Automatic optimization of regions of interest in hyperspectral images for detecting vegetative indices in soybeans | Vegetative indices (VIs) are widely used in high-throughput phenotyping (HTP) for the assessment of plant growth conditions; however, a range of VIs among diverse soybeans is still an unexplored research area. For this reason, we investigated a range of four major VIs: normalized difference vegetation index (NDVI), photochemical reflectance index (PRI), anthocyanin reflectance index (ARI), and change to carotenoid reflectance index (CRI) in diverse soybean accessions. Furthermore, we ensured the correct positioning of the region of interest (ROI) on the soybean leaf and clarified the effect of choosing different ROI sizes. We also developed a Python algorithm for ROI selection and automatic VIs calculation. According to our results, each VI showed diverse ranges (NDVI: 0.60-0.84, PRI: -0.03 to 0.05, ARI: -0.84 to 0.85, CRI: 2.78-9.78) in two different growth stages. The size of pixels in ROI selection did not show any significant difference. In contrast, the shaded part and the petiole part had significant differences compared with the non-shaded and tip, side, and center of the leaf, respectively. In the case of the Python algorithm, algorithm-derived VIs showed a high correlation with the ENVI software-derived value: NDVI -0.97, PRI -0.96, ARI -0.98, and CRI -0.99. Moreover, the average error was detected to be less than 2.5% in all these VIs than in ENVI. | Lee, Sangyeab; Ghimire, Amit; Kim, Yoonha; Lee, Jeong-Dong | Kyungpook Natl Univ, Dept Appl Biosci, Daegu, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu, South Korea; Kyungpook Natl Univ, Upland Field Machinery Res Ctr, Daegu, South Korea | ghimire, amit/KCK-1842-2024 | 59196797100; 57823220200; 57224866763; 40462075100 | kyh1229@knu.ac.kr; jdlee@knu.ac.kr; | FRONTIERS IN PLANT SCIENCE | FRONT PLANT SCI | 1664-462X | 16 | SCIE | PLANT SCIENCES | 2024 | 4.8 | 11.9 | 0 | 2025-05-07 | 0 | 0 | vegetative indices (VIs); hyperspectral imaging; normalized difference vegetation index (NDVI); photochemical reflectance index (PRI); anthocyanin reflectance index (ARI) | PLANT; REFLECTANCE; PERFORMANCE; SELECTION; NITROGEN; BIOMASS; GROWTH; YIELD; WATER | anthocyanin reflectance index (ARI); hyperspectral imaging; normalized difference vegetation index (NDVI); photochemical reflectance index (PRI); vegetative indices (VIs) | English | 2025 | 2025-03-06 | 10.3389/fpls.2025.1511646 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Blockchain-Enabled Secure Collaborative Model Learning Using Differential Privacy for IoT-Based Big Data Analytics | With the rise of Big data generated by Internet of Things (IoT) smart devices, there is an increasing need to leverage its potential while protecting privacy and maintaining confidentiality. Privacy and confidentiality in Big Data aims to enable data analysis and machine learning on large-scale datasets without compromising the dataset sensitive information. Usually current Big Data analytics models either efficiently achieves privacy or confidentiality. In this article, we aim to design a novel blockchain-enabled secured collaborative machine learning approach that provides privacy and confidentially on large scale datasets generated by IoT devices. Blockchain is used as secured platform to store and access data as well as to provide immutability and traceability. We also propose an efficient approach to obtain robust machine learning model through use of cryptographic techniques and differential privacy in which the data among involved parties is shared in a secured way while maintaining privacy and confidentiality of the data. The experimental evaluation along with security and performance analysis show that the proposed approach provides accuracy and scalability without compromising the privacy and security. | Tekchandani, Prakash; Bisht, Abhishek; Das, Ashok Kumar; Kumar, Neeraj; Karuppiah, Marimuthu; Vijayakumar, Pandi; Park, Youngho | Int Inst Informat Technol, Ctr Secur Theory & Algorithm Res, Hyderabad 500032, India; Thapar Univ, Dept Comp Sci & Engn, Patiala 147004, India; Presidency Univ, Sch Comp Sci & Engn & Informat Sci, Bengaluru 560064, India; Univ Coll Engn Tindivanam, Dept Comp Sci & Engn, Villupuram 604001, Tamil Nadu, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | Das, Ashok/ADT-4705-2022; Pandi, Vijayakumar/Y-4636-2019; Karuppiah, Marimuthu/B-2653-2018; Kumar, Neeraj/L-3500-2016 | 58375402000; 58078371600; 55450732800; 57206866080; 57190179294; 57189497709; 56962990300 | prakash.tekchandani@research.iiit.ac.in; abhishek.bisht@research.iiit.ac.in; ashok.das@iiit.ac.in; neeraj.kumar@thapar.edu; marimuthume@gmail.com; vijibond2000@gmail.com; parkyh@knu.ac.kr; | IEEE TRANSACTIONS ON BIG DATA | IEEE T BIG DATA | 2332-7790 | 11 | 1 | SCIE | COMPUTER SCIENCE, THEORY & METHODS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 5.7 | 11.9 | 0 | 2025-05-07 | 1 | 1 | Data models; Blockchains; Big Data; Security; Privacy; Differential privacy; Machine learning; Internet of things (IoT); differential privacy; collaborative model learning; blockchain; big data analytics; security | SCHEME; APPROXIMATION; EFFICIENT; INTERNET | big data analytics; blockchain; collaborative model learning; differential privacy; Internet of things (IoT); security | Blockchain; Data Analytics; Large datasets; Machine learning; Sensitive data; Big data analytic; Block-chain; Collaborative model learning; Collaborative modeling; Data analytics; Differential privacies; Internet of thing; Machine-learning; Model learning; Privacy; Security; Internet of things | English | 2025 | 2025-02 | 10.1109/tbdata.2024.3394700 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Carrier-Based Minimum-Loss Discontinuous PWM With Neutral-Point Voltage Balancing for Three-Level NPC Inverters | This article analyzes zero-clamping possible regions of three-level inverters and investigates the selection criteria for positive, negative, and zero clamping in discontinuous pulsewidth modulation (DPWM). Based on this analysis, a carrier-based minimum-loss DPWM (MLDPWM) is proposed to minimize the switching loss of the three-level inverters. The proposed method further increases the clamping region furthermore in the vicinity of a peak current by applying the zero clamping. Consequently, the switching loss can be minimized by reducing the number of switching near the peak current, considering all ranges of power factor angles and modulation indices. The performance of the proposed method is compared with that of the conventional DPWM method in the aspect of switching loss function. Moreover, the neutral-point voltage balancing is achieved by adjusting the clamping region while maintaining the principles of proposed MLDPWM. Finally, the effectiveness of the proposed method is verified by simulation and experimental results. | Cho, Hyung-June; Sul, Kyoung-Hwan; Kim, Ki-Hyun; Jung, Jae-Jung; Kim, Hyeon-Sik | PLECKO Co Ltd, Gwangmyeong 14322, South Korea; Gachon Univ, Dept Next Generat Smart Energy Syst Convergence, Seongnam 13120, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Gachon Univ, Dept Elect Engn, Seongnam 13120, South Korea | 57203968800; 59755283900; 59194094800; 55368433400; 56704124900 | hjcho@plecko.biz; daniel99s@gachon.ac.kr; rlarlgus5615@knu.ac.kr; jj.jung@knu.ac.kr; hyeonsik@gachon.ac.kr; | IEEE TRANSACTIONS ON POWER ELECTRONICS | IEEE T POWER ELECTR | 0885-8993 | 1941-0107 | 40 | 9 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 6.5 | 11.9 | 0 | 2025-05-07 | 0 | 0 | Clamps; Inverters; Switching loss; Vectors; Switches; Voltage; Space vector pulse width modulation; Voltage control; Electronic mail; Training; Discontinuous pulsewidth modulation (DPWM); minimum loss; neutral-point (NP) balancing; switching loss; three-level inverter | SPACE-VECTOR MODULATION; SWITCHING LOSS; CONVERTER; STRATEGY; REDUCTION; RIPPLE | Discontinuous pulsewidth modulation (DPWM); minimum loss; neutral-point (NP) balancing; switching loss; three-level inverter | Discontinuous pulse-width modulation; Discontinuous PWM; Minimum loss; Neutral point balancing; Neutral-point voltage balancing; Peak currents; Pulsewidth modulations (PWM); Switching loss; Three level NPC inverter; Three-level inverters | English | 2025 | 2025-09 | 10.1109/tpel.2025.3564385 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Establishment of efficient hypocotyl-derived protoplast isolation and its application in soybean (Glycine max [L.] Merr.) | Soybean is important crop species in agriculture, food science, and biotechnology due to their valuable components. The exploration of soybean genetic traits is being highlighted for the advancement of research in various aspects. The utilization of plant biotechnology, plant protoplast techniques, for the study of genetic characteristics is being extended to various agricultural crop species. The quintessential goal of genetic characterization utilizing plant protoplasts encompasses the provision of stable plant protoplasts alongside the establishment of transfection condition. Despite the numerous studies on protoplast isolation, standardized and reliable soybean protoplasts protocols for comprehensive investigations into the intricate regulatory mechanisms governing immune responses, cellular processes, and developmental pathways remain insufficiently established. In this study, we propose an efficient methodology for the protoplast isolation and the PEG-Ca2+ mediated transfection of soybean [Glycine max (L.) Merr.] cultivar (Williams 82). The protoplast isolation entailed the evaluation of variables including mannitol concentration, enzyme mixture composition, and enzymatic digestion duration. The optimal conditions for hypocotyl-derived protoplast isolation were identified as 0.4 M mannitol, an enzyme mixture containing 1.5% (w/v) cellulase and 0.4% (w/v) macerozyme, and an 8-hour enzymatic digestion period, resulting in high viability and protoplast yield (>3.0 x 10(6)/g FW). For the PEG-Ca2+ mediated transfection process, the parameters assessed including PEG concentration, plasmid quantify or purified recombinant proteins, and PEG-Ca2+ incubation duration. The validation of the reliability of hypocotyl-derived protoplast system through transient gene expression demonstrates its utility as a robust platform for analysis of genetic traits in soybean. This could extend the scope of application to understanding the cell-to-cell interactions for physiological responses in soybean. | Kim, Kihwan; Shin, Junseop; Lee, Jeong-Dong; Kim, Won-Chan | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Upland Field Machinery Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu, South Korea | 57210357476; 59926421200; 40462075100; 55492085000 | jdlee@knu.ac.kr; kwc@knu.ac.kr; | FRONTIERS IN PLANT SCIENCE | FRONT PLANT SCI | 1664-462X | 16 | SCIE | PLANT SCIENCES | 2024 | 4.8 | 11.9 | 0 | 2025-06-11 | 0 | 0 | Glycine max; hypocotyl-derived protoplast; PEG-Ca2+ mediated transfection; protoplast yield; transient gene expression | CELL-CELL INTERACTIONS; MESOPHYLL PROTOPLASTS; GENE-EXPRESSION; SOY PROTEIN; TRANSFORMATION; CULTURE; SYSTEM; PRODUCTS; MAIZE; ERA | Glycine max; hypocotyl-derived protoplast; PEG-Ca<sup>2+</sup> mediated transfection; protoplast yield; transient gene expression | English | 2025 | 2025-05-20 | 10.3389/fpls.2025.1587927 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Exploring the role of ATP-binding cassette transporters in tomato (Solanum lycopersicum) under cadmium stress through genome-wide and transcriptomic analysis | ATP-binding cassette (ABC) transporters are integral membrane proteins involved in the active transport of various substrates, including heavy metals, across cellular membrane. In this study, we performed a genome-wide analysis and explored the expression profiles of ABC transporter genes in Solanum lycopersicum to identify their role in cadmium (Cd) stress tolerance. Several techniques were employed to determine the regulatory role of ABC transporters. A total of 154 ABC transporter genes were identified in the genome of S. lycopersicum, located on all 12 chromosomes. Comparative phylogenetic analysis between S. lycopersicum and Arabidopsis thaliana revealed several orthologous gene pairs, which were duly supported by the structural analysis of the genes by studying the exon-intron pattern and motif analysis. Collinearity analysis revealed multiple gene duplication events owing to intra-chromosomal and inter-chromosomal mutations. The cis-regulatory analysis identified several hormone-responsive elements suggesting that ABCs are actively involved in transporting hormones like ABA, SA, MeJA, auxin, and gibberellin. These hormones are known to combat a number of stress conditions, hence validating the role of ABCs in Cd stress. Under Cd stress, expression profiling demonstrated that several SlABCs exhibit significant transcriptional changes, indicating their involvement in Cd transport, sequestration, and detoxification mechanisms. Specific genes, including Groups 3 and 5 members, were upregulated under Cd exposure, suggesting their functional roles in mitigating Cd toxicity. The study revealed differential expressions of various SlABC genes encoding ATP binding cassette transporters, including the upregulation of several genes like Solyc08g067620.2, Solyc08g067610.3, Solyc12g019640.2, Solyc06g036240.2, and Solyc05g053610.2 in response to different concentrations of Cd. This study comprehensively explains the ABC transporter gene family in S. lycopersicum, emphasizing their critical roles in Cd stress tolerance. This study could prove useful in combating Cd stress not only in S. lycopersicum but also in other fleshy fruit plants; however, further advanced studies on specific pathways that lead to differential expression of the ABC genes are required to understand the mechanism behind tolerance to heavy metals fully. | Hashmi, Syed Salman; Bilal, Saqib; Jan, Rahmatullah; Asif, Saleem; Abdelbacki, Ashraf M.

| ○ | ○ | Article | Identification and evaluation of low-pH-tolerant Cheongcheong/Nagdong-double haploid rice lines via QTL analysis | Low soil pH (acidic soil) is one of the most severe environmental constraints that severely inhibits crop production. Here, we screened 134 lines of the Cheongcheong/Nagdong Double Haploid (CNDH) rice population under low pH conditions to uncover candidate QTLs and identify low pH-resistant lines. A total of 17 QTLs against shoot length, root length and standard evaluation score in response to low pH were identified on 8 chromosomes (1, 2, 6, 7, 8, 9, 10, and 12). A QTL related to shoot length, qSL-6b, on chromosome 6 with an LOD of 5 and a QTL related to the standard evaluation score, qSES-9, on chromosome 6 with an LOD of 3 were further investigated for candidate genes. A total of 24 genes were predicted, i.e., 17 genes on qSL-6b and 7 genes on qSES-9 on the basis of closely related functional annotations via the NCBI and RiceXPro databases. Through qRT-PCR of the resistant and susceptible lines, we identified four genes (Os06g0211200, Os09g0448200, Os09g0456200, and Os09g0472100) that were significantly expressed in the resistant lines but expressed at lower levels in the susceptible lines under low-pH soil stress. During early germination, ABA levels decreased in all the resistant lines but increased in all the susceptible lines. However, the ABA level at the seedling stage significantly increased in the resistant lines but decreased in all the susceptible lines. Our results suggest that the genes responsible for K+ ion homeostasis and ABA regulation play key roles in resistance to low pH in rice. | Jan, Rahmatullah; Kim, Nari; Asif, Saleem; Asaf, Sajjad; Lubna, Muhammad; Farooq, Muhammad; Khan, Zakirullah; Kim, Kyung-Min | Kyungpook Natl Univ, Coastal Agr Res Inst, Daegu 41566, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Appl Biosci, Daegu 41566, South Korea; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa, Oman; Jeonbuk Natl Univ, Coll Agr & Life Sci, Dept Agr Biol, Jeonju, South Korea | Jan, Rahmatullah/AIC-3439-2022; Asaf, Sajjad/ABA-3647-2021 | 57201981969; 57395985700; 57396413700; 56595059900; 59658046000; 59899372800; 58810294300; 34868260300 | sajadasif2000@gmail.com; kkm@knu.ac.kr; | BMC PLANT BIOLOGY | BMC PLANT BIOL | 1471-2229 | 25 | 1 | SCIE | PLANT SCIENCES | 2024 | 4.8 | 11.9 | 0 | 2025-05-07 | 0 | 0 | Low soil pH (acidic soil); QTLs; Standard evaluation score; Candidate genes; ABA regulation; K+ ion homeostasis | DROUGHT STRESS TOLERANCE; ABSCISIC-ACID; PLASMA-MEMBRANE; ARABIDOPSIS-THALIANA; WATER TRANSPORT; SIGNAL-TRANSDUCTION; CYTOSOLIC PH; ROOT MEDIUM; ALUMINUM; ABA | ABA regulation; Candidate genes; K<sup>+</sup> ion homeostasis; Low soil pH (acidic soil); QTLs; Standard evaluation score | Chromosome Mapping; Chromosomes, Plant; Genes, Plant; Haploidy; Hydrogen-Ion Concentration; Oryza; Quantitative Trait Loci; Soil; chemistry; chromosomal mapping; genetics; growth, development and aging; haploidy; Oryza; pH; physiology; plant chromosome; plant gene; quantitative trait locus; soil | English | 2025 | 2025-04-25 | 10.1186/s12870-025-06538-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Identification of Resonance and Instability from Algebraic Virtual Impedance of Grid-Forming Control in the Perspective of Negative Sequence | Virtual impedance (VI) is commonly implemented in a static manner, typically neglecting the derivative term. This letter investigates fundamental issues associated with algebraic virtual impedance (AVI), emphasizing its characteristics related to negative-sequence impedance. The analysis reveals that AVI exhibits capacitive behavior in the negative-sequence impedance, inducing significant harmonic currents near a particular negative resonant frequency. Furthermore, the influence of control delay is analyzed, illustrating that AVI can readily become non-passive within the negative-frequency region of the frequency domain, leading to harmonic instability. Experimental results are provided to validate the theoretical analysis. © 1986-2012 IEEE. | Lee, Jaekeun; Maeng, Junyeol; Jung, Jae-Jung; Cui, Shenghui | Seoul National University, Department of Electrical and Computer Engineering, SNU Electric Power Research Institute, Seoul, 08826, South Korea; Seoul National University, Department of Electrical and Computer Engineering, SNU Electric Power Research Institute, Seoul, 08826, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, 41566, South Korea; Seoul National University, Department of Electrical and Computer Engineering, SNU Electric Power Research Institute, Seoul, 08826, South Korea | 59096401900; 58931398300; 55368433400; 56157479900 | cuish@snu.ac.kr; | IEEE Transactions on Power Electronics | IEEE T POWER ELECTR | 0885-8993 | 1941-0107 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 6.5 | 11.9 | 0 | 2025-06-11 | 0 | negative-sequence component; passivity; resonance; stability; Virtual impedance | Algebra; Cutoff frequency; Digital arithmetic; Negative resistance; Stabilization; Capacitive behavior; Control delay; Frequency regions; Harmonic currents; Negative frequency; Negative sequence; Negative sequence components; Passivity; Sequence impedances; Virtual impedance; Natural frequencies | English | Article in press | 2025 | 10.1109/tpel.2025.3571387 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | The stress-induced gene AtDUF569 positively regulates salt stress responses in Arabidopsis thaliana | BackgroundFrequent drought and high soil salinity are significant stressors that hinder crop yields worldwide. Understanding gene regulation and underlying stress responses in plants is key to combating abiotic stress. Recent reports have implicated the domain-of-unknown-function (DUF) proteins in plant stress responses. In Arabidopsis, AtDUF569 regulates plant growth and development under oxidative as well as nitro-oxidative stress and modulates plant basal defense.ResultsHere, we describe how AtDUF569 bolsters plant responses to salt stress. The atduf569 mutant plants demonstrated a salt-resistant phenotype. The expression of salt overly sensitive (SOS) pathway genes, nitrate reductase, abscisic acid (ABA)-dependent stress-induced genes, and other stress-related genes were altered in atduf569 plants in comparison to wild type. We also measured antioxidant activity, chlorophyll, polyphenol, flavonoid, total carotenoid, protein, malondialdehyde (MDA), ABA, and amino acid content; atduf569 plants had significantly lower levels of superoxide dismutase and polyphenol oxidase, total chlorophyll, polyphenol, flavonoid, carotenoid, protein, and ABA, though a significant increase in MDA content was observed.ConclusionThese results indicate that AtDUF569 positively regulates plant responses to salt stress by modulating the expression of SOS pathway genes, potentially through transcriptional or indirect regulatory mechanisms, antioxidant defense and streamlining, photosynthesis, ABA, and secondary metabolites production. | Nabi, Rizwana Begum Syed; Tayade, Rupesh; Deshmukh, Rupesh; Hussain, Adil; Shahid, Muhammad; Adhikari, Arjun; Abuqamar, Synan F.; Yun, Byung-Wook | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Natl Inst Crop Sci, Rural Dev Adm, Dept Southern Area Crop Sci, Miryang 50424, South Korea; Cent Univ Haryana, Dept Biotechnol, Mahendragarh 23031, Haryana, India; Abdul Wali Khan Univ, Dept Agr, Mardan 23200, Pakistan; United Arab Emirates Univ, Coll Sci, Dept Biol, Al Ain 15551, U Arab Emirates | AbuQamar, Synan/AAV-1229-2021; Tayade, Rupesh/AAM-9652-2021; Adhikari, Arjun/AAV-6297-2021 | 57200232212; 57191753234; 35765186600; 41961162600; 59577718600; 57195601415; 12806366100; 8245123600 | sabuqamar@uaeu.ac.ae; bwyun@knu.ac.kr; | BMC PLANT BIOLOGY | BMC PLANT BIOL | 1471-2229 | 25 | 1 | SCIE | PLANT SCIENCES | 2024 | 4.8 | 11.9 | N/A | 0 | 0 | Abscisic acid; Antioxidant; Arabidopsis; AtDUF569; Salt overly sensitive; Salt stress | NITRIC-OXIDE; LIPID-PEROXIDATION; DROUGHT TOLERANCE; ABSCISIC-ACID; RICE; EXPRESSION; SALINITY; GROWTH; ACCUMULATION; NETWORKS | Abscisic acid; Antioxidant; Arabidopsis; AtDUF569; Salt overly sensitive; Salt stress | Abscisic Acid; Arabidopsis; Arabidopsis Proteins; Gene Expression Regulation, Plant; Salt Stress; Salt Tolerance; abscisic acid; Arabidopsis protein; Arabidopsis; drug effect; gene expression regulation; genetics; metabolism; physiology; salt stress; salt tolerance | English | 2025 | 2025-05-05 | 10.1186/s12870-025-06618-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
