| ○ | ○ | Article | Correlations and energy in mediated dynamics | The minimum time required for a quantum system to evolve to a distinguishable state is set by the quantum speed limit, and consequently influences the change of quantum correlations and other physical properties. Here we study the time required to maximally entangle two principal systems interacting either directly or via a mediating ancillary system, under the same energy constraints. The direct interactions are proved to provide the fastest way to entangle the principal systems, but it turns out that there exist mediated dynamics that are just as fast. We show that this can only happen if the mediator is initially correlated with the principal systems. These correlations can be fully classical and can remain classical during the entangling process. The final message is that correlations save energy: one has to supply extra energy if maximal entanglement across the principal systems is to be obtained as fast as with an initially correlated mediator. | Krisnanda, Tanjung; Lee, Su-Yong; Noh, Changsuk; Kim, Jaewan; Streltsov, Alexander; Liew, Timothy C.

| ○ | ○ | Article | Intramedullary nailing of subtrochanteric fractures in elderly patients: Comparative study of helical blade cephalomedullary nail versus reconstruction nail | Introduction: Intramedullary nailing (IMN), which is a common method for treating subtrochanteric frac-tures, is conducted as cephalomedullary (CMN) or reconstruction (RCN) nailing. Numerous studies have reported the effectiveness of CMN, which requires a shorter surgery time and provides stronger fixation strength with blade-type devices. However, the radiographic and clinical outcomes of the use of CMN and RCN in elderly patients aged >= 65 years have not been compared yet. This study aimed to investigate whether CMN offers superior outcomes over RCN in the treatment of subtrochanteric fractures in elderly patients. Materials and methods: This retrospective study included 60 elderly patients (17 men and 43 women; mean age: 74.9 years) diagnosed with subtrochanteric fractures and treated with IMN with helical blade CMN (CMN group: 30 patients) or RCN (RCN group: 30 patients) between January 2013 and December 2018 with at least 1 year of follow-up period. Radiologic outcomes were evaluated based on the postop-erative state of alignment and the achievement and timing of bony union at the final follow-up. Clinical outcomes were evaluated using the Merle d'Aubigne-Postel score. Radiologic and clinical outcomes in the two groups were compared and analyzed, and the occurrence of complications was examined. Results: The difference in malalignment between the two groups was not significant; however, the RCN group achieved more effective reduction. At the final follow-up, bony union was achieved within 18.9 weeks, on average, in 28 patients in the CMN group and within 21.6 weeks, on average, in 27 patients in the RCN group. Twenty patients in the CMN group and 26 in the RCN group showed good or better results according to the Merle d'Aubigne-Postel score. No significant differences were found for any of the parameters. Conclusions: In the treatment of difficult subtrochanteric fractures in elderly patients, RCN can provide excellent reduction and strong fixation similar to CMN and can result in outstanding clinical and radio-logic outcomes.

| ○ | ○ | Article | Topological and quantum stability of low-dimensional crystalline lattices with multiple nonequivalent sublattices* | The terms of topological and quantum stabilities of low-dimensional crystalline carbon lattices with multiple non-equivalent sublattices are coined using theoretical analysis, multilevel simulations, and available experimental structural data. It is demonstrated that complex low-dimensional lattices are prone to periodicity breakdown caused by structural deformations generated by linear periodic boundary conditions (PBC). To impose PBC mandatory limitations for complex low-dimensional lattices, the topology conservation theorem (TCT) is introduced, formulated and proved. It is shown that the lack of perfect filling of planar 2D crystalline space by structural units may cause the formation of (i) structure waves of either variable or constant wavelength; (ii) nanotubes or rolls; (iii) saddle structures; (iv) aperiodic ensembles of irregular asymmetric atomic clusters. In some cases the lattice can be stabilized by aromatic resonance, correlation effects, or van-der-Waals interactions. The effect of quantum instability and periodicity breakdown of infinite structural waves is studied using quasiparticle approach. It is found that both perfect finite-sized, or stabilized structural waves can exist and can be synthesized. It is shown that for low-dimensional lattices prone to breakdown of translation invariance (TI), complete active space of normal coordinates cannot be reduced to a subspace of TI normal coordinates. As a result, constrained TI subspace structural minimization may artificially return a regular point at the potential energy surface as either a global/local minimum/maximum. It is proved that for such lattices, phonon dispersion cannot be used as solid and final proof of either stability or metastability. It is shown that ab initio molecular dynamics (MD) PBC Nose-Hoover thermostat algorithm constrains the linear dimensions of the periodic slabs in MD box preventing their thermostated equilibration. Based on rigorous TCT analysis, a flowchart algorithm for structural analysis of low-dimensional crystals is proposed and proved to be a powerful tool for theoretical design of advanced complex nanomaterials. | Avramov, Pavel, V; Kuklin, Artem, V | Kyungpook Natl Univ, Coll Nat Sci, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea; Uppsala Univ, Dept Phys & Astron, Box 516, SE-75120 Uppsala, Sweden | Kuklin, Artem/A-9007-2014 | 7004322420; 56035188600 | paul.veniaminovich@knu.ac.kr; | NEW JOURNAL OF PHYSICS | NEW J PHYS | 1367-2630 | 24 | 10 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2022 | 3.3 | 35.9 | 1.14 | 2025-06-25 | 15 | 14 | low-dimensional lattices; topology conservation theorem; topological stability; quantum stability; periodic boundary conditions; phonon dispersion; molecular dynamics | DENSITY-FUNCTIONAL THERMOCHEMISTRY; REVERSIBLE HYDROGENATION; ELECTRONIC-PROPERTIES; MOLECULAR-DYNAMICS; PENTA-GRAPHENE; FORCE-FIELD; BASIS-SET; CARBON; SIMULATION; GRAPHITE | low-dimensional lattices; molecular dynamics; periodic boundary conditions; phonon dispersion; quantum stability; topological stability; topology conservation theorem | Boundary conditions; Crystal atomic structure; Phonons; Potential energy; Quantum chemistry; Quantum theory; Stability; Structural analysis; Topology; Van der Waals forces; Conservation theorem; Low dimensional; Low-dimensional lattice; Periodic boundary conditions; Phonon dispersions; Quantum stability; Sub-lattices; Topological stability; Topology conservation theorem; Translation invariance; Molecular dynamics | English | 2022 | 2022-10-01 | 10.1088/1367-2630/ac93a9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Usefulness of the d-dimer to albumin ratio for risk assessment in patients with acute variceal bleeding at the emergency department: retrospective observational study | Background Acute variceal bleeding (AVB) is a severe complication of portal hypertension that is caused by rupture of the esophageal or gastric varix. Scoring system for risk stratification of AVB is difficult to use because various variables must be entered, and it is difficult to apply early in the emergency department (ED). We compared and analyzed the usefulness of the D-dimer to albumin ratio (DAR) for risk stratification of AVB. Methods In this retrospective observational study, medical records of patients with AVB Between January 2019 and December 2020 were assessed. The primary endpoint was to evaluate whether DAR was a predictor of clinical outcomes for AVB. Receiver operating characteristic (ROC) curves were constructed using cut-off values determined by the Youden Index. Univariate and multivariate logistic regression analyses were performed to assess the factors contributing to the development of outcomes. Results Overall, 67 patients required intensive care. The cut-off value of DAR for patients requiring intensive care was 400. A DAR > 400 (adjusted HR: 5.636 [95% CI: 2.216-14.332]) independently predicted the need for ICU admission in these patients. Overall, 13 patients required long-term hospitalization. The cut-off value of DAR for patients requiring long-term hospitalization was 403. A DAR > 403 (adjusted HR: 9.899 [95% CI: 2.012-48.694]) independently predicted the need for long-term hospitalization. Overall, 95 patients required transfusion. The cut-off value of DAR for patients requiring transfusion was 121. A DAR > 121 (adjusted HR: 4.680 [95% CI: 1.703-12.862]) independently predicted the need for transfusion. Overall, 11 patients died during study period. The cut-off value of DAR for mortality was 450. A DAR > 450 (adjusted HR: 26.261 [95% CI: 3.054-225.827]) independently predicted mortality. Conclusions The DAR can be used for outcome assessment in patients with AVB with various scoring systems, but its explanatory power is not high. | Seo, Jun Seok; Kim, Yongwon; Lee, Yoonsuk; Chung, Ho Young; Kim, Tae Youn | Dongguk Univ, Ilsan Hosp, Coll Med, Dept Emergency Med, 27 Dongguk Ro, Goyang Si, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med Informat, Daegu, South Korea; Yonsei Univ, Wonju Coll Med, Dept Emergency Med, Wonju, South Korea | ; Kim, Yong Won/AAA-2134-2022; 김, 태윤/ISB-8410-2023 | 55614793100; 57216647417; 57212624590; 56008255800; 57210850595 | emkty@dumc.or.kr; | BMC EMERGENCY MEDICINE | BMC EMERG MED | 1471-227X | 22 | 1 | SCIE | EMERGENCY MEDICINE | 2022 | 2.5 | 35.9 | 0.24 | 2025-06-25 | 1 | 1 | Esophageal and Gastric Varices; Risk assessment; D-dimer; albumin | IN-HOSPITAL MORTALITY; STAGE LIVER-DISEASE; INTENSIVE-CARE; CHILD-PUGH; SCORE; HYPOALBUMINEMIA; CIRRHOSIS; PROGNOSIS; MODEL | albumin; D-dimer; Esophageal and Gastric Varices; Risk assessment | Albumins; Emergency Service, Hospital; Esophageal and Gastric Varices; Fibrin Fibrinogen Degradation Products; Gastrointestinal Hemorrhage; Humans; Retrospective Studies; Risk Assessment; albumin; D dimer; albuminoid; fibrin degradation product; fibrin fragment D; acute variceal bleeding; adult; Article; bleeding; clinical outcome; controlled study; diagnostic test accuracy study; diagnostic value; emergency ward; female; hospital admission; hospitalization; human; intensive care unit; major clinical study; male; middle aged; mortality rate; observational study; retrospective study; risk assessment; complication; esophagus varices; gastrointestinal hemorrhage; hospital emergency service; risk assessment | English | 2022 | 2022-07-25 | 10.1186/s12873-022-00696-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | 7 T Niobium-Titanium-Based Persistent-Mode Superconducting Magnet for an Electron Beam Ion Source | A high field magnet is a key element of cryogenic electron beam ion sources (EBISs), which are known for generating highly charged ions through the magnetic compression of an electron beam. Herein, we report the design, fabrication, and evaluation of a 7 T niobium-titanium superconducting magnet capable of persistent-mode operation. The magnet was designed using finite element analysis by considering its magnetic, thermal, and mechanical properties. The designed magnet was then fabricated, assembled, and evaluated for various design parameters in a recondensing-type liquid helium cryostat. After several quench trainings, the magnet reached a target magnetic field of 7 T with an operating current of 200 A, a magnetic field uniformity of 0.24%, and an electron beam focusing length of 1.3 m inside the bore. The magnet was successfully operated in the persistent-mode for 9.5 days (228 hours) and achieved a field-decay rate of 0.42 ppm.h(-1) . The magnet evaluation results confirm that our superconducting magnet system can be applied to an EBIS to carry out stable and effective electron beam compression. | Kim, Su-Hun; Patel, Dipak; Jeong, Yeundae; Kim, Minhee; Lee, Se-Hee; Kim, Jung Ho; Choi, Seyong | Kyungpook Natl Univ, Dept Elect Engn, Daegu 41566, South Korea; Univ Queensland, Sch Mech & Min Engn, St Lucia, Qld 4067, Australia; KR Tech, Daegu 41059, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Univ Wollongong, Australian Inst Innovat Mat, Inst Superconducting & Elect Mat, Squires Way,Innovat Campus, North Wollongong, NSW 2500, Australia; Kangwon Natl Univ, Dept Elect Engn, Kangwon 25914, South Korea | ; Patel, Dipak/G-8293-2014; Kim, Jung Ho/D-4097-2014; Kim, Minhee/LRT-2058-2024; Kim, Su-Hun/AAB-5569-2020; Choi, Seyong/AAB-5572-2020 | 57188669953; 26040989200; 57441180100; 57214228950; 55009905600; 35215131600; 7408122787 | jhk@uow.edu.au;syc@kangwon.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 0 | 2025-06-25 | 0 | 0 | Superconducting magnets; Magnetomechanical effects; Wires; Magnetic flux; Magnetic fields; Stress; Magnetic resonance imaging; Niobium-titanium magnet; persistent-mode operation; persistent current switch; electron beam ion source; finite element method | DESIGN | Magnetic fields; Magnetic flux; Magnetic resonance imaging; Magnetomechanical effects; Stress; Superconducting magnets; Wires | Binary alloys; Decay (organic); Electron beams; Electrons; Ion sources; Magnetic fields; Niobium; Niobium alloys; Superconducting magnets; Superconducting materials; Superfluid helium; Titanium; Titanium alloys; Electron beam ion source; Electron-beam; High field magnets; Mode operation; Niobium-titania magnet; Niobium-titanium; Persistent current switch; Persistent mode; Persistent-mode operation; Titanium-based; Finite element method | English | 2022 | 2022 | 10.1109/access.2022.3147589 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | A Decade Review on Smart Cities: Paradigms, Challenges and Opportunities | Smart City has been an emerging research domain for Government, Businesses, and researchers in the last few years. The Indian government is also interested and investing lots of funds to develop smart cities. These cities are technology-based and require interdisciplinary research and development for successful implementation. Over the last few decades, various technological interventions have created a tendency to provide smart everyday objects to make human life more comfortable. The emergence of the smart city paradigm is a response to creating a future city that guarantees the well-being and rights of its citizens from the perspective of industrial development: industry, urban planning, environment, and sustainable development. There are several subdomains in the smart city for the research. To work with the different subdomains in a smart city, proper guidance about the background of the smart city is required. This research paper is a guide for the same. This research paper represents a systematic literature review of the smart city domain. This paper carries out a systematic review of research papers published in various well-reputed journals like IEEE, Springer, Elsevier, etc., between 2011 and 2021. This paper will help the government, businesses, and researchers aiming to enhance the smart city concept. Initially, this paper discusses the origin and emergence of this concept, followed by a few definitions and characteristics with the real roadmap and primary supporting pillars of the smart city. This paper discusses a typical architecture having different layers like Sensing, Transportation, Data Management, and Application Layers. There are various supporting technologies and platforms for the smart city; hence implementations are impossible without these technologies and media. This research paper discusses different components of the smart city. A broad literature survey is being done to observe various challenges, opportunities, and future trends in the smart city. This research paper can guide the researchers and provide the research direction in the smart city domain. | Singh, Tarana; Solanki, Arun; Sharma, Sanjay Kumar; Nayyar, Anand; Paul, Anand | Gautam Buddha Univ, Dept Comp & Engn, Greater Noida 201308, Uttar Pradesh, India; Duy Tan Univ, Fac Informat Technol, Grad Sch, Da Nang 550000, Vietnam; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | ; Paul, Anand/V-6724-2017; Sharma, Sanjay/AAR-2495-2020; Nayyar, Anand/F-3732-2015; Nayyar, Dr. Anand/F-3732-2015 | 57216931483; 36562669800; 57226023303; 55201442200; 56650522400 | taranasingh14@gmail.com;paul.editor@gmail.com; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 2.7 | 2025-06-25 | 63 | 104 | Smart cities; Urban areas; Government; Technological innovation; Sustainable development; Bibliometrics; Market research; Smart city; Internet of Things; big data; cloud computing; sustainability; cyber-physical system | BIG DATA; ENERGY MANAGEMENT; SENSOR NETWORKS; DATA ANALYTICS; CITY; INTERNET; IOT; THINGS; SYSTEM; ARCHITECTURE | big data; cloud computing; cyber-physical system; Internet of Things; Smart city; sustainability | Big data; Distributed computer systems; Embedded systems; Information management; Internet of things; Planning; Smart city; Sustainable development; Urban planning; Bibliometric; Cloud-computing; Cybe-physical systems; Cyber-physical systems; Government; Market researches; Research papers; Subdomain; Technological innovation; Urban areas; Cyber Physical System | English | 2022 | 2022 | 10.1109/access.2022.3184710 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Fast Weight Transfer Method for Real-Time Online Learning in RRAM-Based Neuromorphic System | In this work, a synaptic weight transfer method for a neuromorphic system based on resistive-switching random-access memory (RRAM) is proposed and validated. To implement the on-chip trainable neuromorphic system which utilizes large-scale hardware synapse units, a fast and reliable write scheme needs to be established. Based on the experimental results, it is confirmed that the gradual set and full reset operation is the most suitable operation scheme for fast programming due to the fundamental reliability characteristics of the resistive-switching memory cell. Also, the superiority of this programming method using the proposed RRAM compact model is demonstrated. In addition, a one weight/one synaptic device structure is newly adopted for realizing high-density synapse arrays by using a nonnegative weight constraint in supervised learning. Finally, the pattern recognition accuracies obtained at the software and hardware levels are compared. | Kim, Min-Hwi; Lee, Sin-Hyung; Kim, Sungjun; Park, Byung-Gook | Seoul Natl Univ, Interuniv Semicond Res Ctr ISRC, Seoul 08826, South Korea; Seoul Natl Univ, Dept Elect & Comp Engn, Seoul 08826, South Korea; Samsung Elect Co, Memory Business Div, Hwaseong Si 18448, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Sch Elect, Daegu 702701, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 702701, South Korea; Dongguk Univ, Div Elect & Elect Engn, Seoul 04620, South Korea | Lee, Sin-Hyung/ABD-6425-2022; Kim, Sungjun/G-7884-2018 | 56647038300; 57226880204; 57216749210; 57221622173 | sungjun@dongguk.edu;bgpark@snu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 0.97 | 2025-06-25 | 10 | 11 | Switches; Synapses; Conductivity; Neuromorphics; Integrated circuit modeling; Immune system; Hardware; Neuromorphic; hardware-driven artificial intelligence; synaptic device; weight transfer; resistive-switching random-access memory (RRAM); artificial neural network (ANN); cross-point array architecture | MEMORY | artificial neural network (ANN); cross-point array architecture; hardware-driven artificial intelligence; Neuromorphic; resistive-switching random-access memory (RRAM); synaptic device; weight transfer | Immune system; Pattern recognition systems; RRAM; Switching; Time switches; Timing circuits; Array architecture; Artificial neural network; Conductivity; Cross-point array; Cross-point array architecture; Hardware; Hardware-driven artificial intelligence; Integrated circuit modeling; Neuromorphic; Random access memory; Resistive switching; Resistive-switching random-access memory; Synapse; Synaptic device; Weight transfer; Neural networks | English | 2022 | 2022 | 10.1109/access.2022.3157333 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A High Gain OTA With Positive Feedback for Ultra-Low Power Applications | This paper presents an ultra-low power operational transconductance amplifier (OTA) operating in the weak inversion region. To increase dc gain, two partial positive feedbacks are used in the input differential pair and its active loads of a current mirror OTA. For further gain improvement, the output resistance is enhanced by increasing the channel length of the output transistors. To understand the operation of this new OTA, dc transfer function as well as small-signal voltage transfer function are derived. In addition, the stable operation for positive feedback is verified through Monte Carlo analysis, root locus plot, and pole scatter plot for a feedback amplifier. The design and simulation of the OTA is performed using 0.18 mu m CMOS technology. Compared to a normal OTA without positive feedback, this OTA features a dc gain enhancement of 36.08 dB, a slew rate improvement of 435.71%, and a unity-gain bandwidth enhancement of 6.68 times. Finally, the designed OTA dissipates an ultra-low power of 41.42 nW. | Park, Sung Sik; Yu, Sang Dae | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 57208531780; 7405733140 | sdyu@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 0.71 | 2025-06-25 | 4 | 8 | Operational transconductance amplifier; positive feedback; low power; weak inversion | low power; Operational transconductance amplifier; positive feedback; weak inversion | Electric resistance; Feedback amplifiers; Low power electronics; Timing circuits; Transconductance; Transfer functions; Circuit stability; DC gain; Gain; High gain; Low Power; Simulation; Stability analyze; Ultra-low power; Ultralow power application; Weak inversions; Operational amplifiers | English | 2022 | 2022 | 10.1109/access.2022.3175584 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | A Robust Approach for Brain Tumor Detection in Magnetic Resonance Images Using Finetuned EfficientNet | A brain tumor is a disorder caused by the growth of abnormal brain cells. The survival rate of a patient affected with a tumor is difficult to determine because they are infrequent and appear in various forms. These tumors can be identified through Magnetic Resonance (MRI) Images, which plays an essential role in determining the tumor site; however, manual detection is a time-consuming and challenging procedure that can cause some errors in results. The adoption of computer-assisted approaches is essential to help in overcoming these constraints. With the advancement of artificial intelligence, deep learning (DL) models are being used in medical imaging to diagnose brain tumors using MR images. In this study, a deep convolutional neural network (CNN) EfficientNet-B0 base model is fine-tuned with our proposed layers to efficiently classify and detect brain tumor images. The image enhancement techniques are used by applying various filters to enhance the quality of the images. Data augmentation methods are applied to increase the data samples for better training of our proposed model. The results show that the proposed fine-tuned state-of-the-art EfficientNet-B0 outperforms other CNN models by achieving the highest classification accuracy, precision, recall, and area under curve values surpassing other state-of-the-art models, with an overall accuracy of 98.87% in terms of classification and detection. Other DL algorithms such as VGG16, InceptionV3, Xception, ResNet50, and InceptionResNetV2 are used for comparative analysis. | Shah, Hasnain Ali; Saeed, Faisal; Yun, Sangseok; Park, Jun-Hyun; Paul, Anand; Kang, Jae-Mo | Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Comp Sci & Engn, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Informat & Commun Engn, Busan 48513, South Korea | ; Park, Jun-Hyun/CAG-5910-2022; Paul, Anand/V-6724-2017 | 57762344700; 58165089300; 56115729600; 57455816200; 56650522400; 56024930400 | jmkang@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 17.92 | 2025-06-25 | 91 | 203 | Tumors; Brain modeling; Magnetic resonance imaging; Cancer; Feature extraction; Convolutional neural networks; Medical services; Brain tumor; deep learning; convolution neural networks (CNN); transfer learning; MRI; detection | Brain tumor; convolution neural networks (CNN); deep learning; detection; MRI; transfer learning | Brain; Convolution; Deep neural networks; Feature extraction; Image enhancement; Magnetism; Medical imaging; Resonance; Tumors; Brain modeling; Brain tumors; Cancer; Convolution neural network; Convolutional neural network; Deep learning; Detection; Features extraction; Medical services; Transfer learning; Magnetic resonance imaging | English | 2022 | 2022 | 10.1109/access.2022.3184113 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Secure and Anonymous User Authentication Scheme for IoT-Enabled Smart Home Environments Using PUF | With the continuous development of Internet of Things (IoT) technology, research on smart home environments is being conducted by many researchers. In smart home environments, home users can remotely access and control a variety of home devices such as smart curtains, lights, and speakers placed throughout the house. Despite providing convenient services, including home monitoring, temperature management, and daily work assistance, smart homes can be vulnerable to malicious attacks because all messages are transmitted over insecure channels. Moreover, home devices can be a target for device capture attacks since they are placed in physically accessible locations. Therefore, a secure authentication and key agreement scheme is required to prevent such security problems. In 2021, Zou et al. proposed a two-factor-based authentication and key agreement scheme using elliptic curve cryptography (ECC) in smart home environments. They claimed that their scheme provides user anonymity and forward secrecy. However, we prove that their scheme suffers from forgery, ephemeral secret leakage, and session key disclosure attacks. To overcome the security vulnerabilities of Zou et al.'s scheme and provide home users with secure communication in smart home environments, we propose a secure user authentication scheme using physical unclonable functions (PUF). We utilize Real-or-Random (ROR) model and Burrows-Abadi-Needham (BAN) logic to verify the session key security and mutual authentication of the proposed scheme, respectively. Furthermore, we use the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool to simulate the resistance of our scheme to security attacks. After that, we analyze and compare the communication costs, computational consumption, and security functionalities along with related schemes. | Cho, Yeongjae; Oh, Jihyeon; Kwon, Deokkyu; Son, Seunghwan; Lee, Joonyoung; Park, Youngho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57826219200; 57222066296; 57221739597; 57221744477; 57203970123; 56962990300 | parkyh@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 2.75 | 2025-06-25 | 18 | 32 | Authentication; Smart homes; Security; Logic gates; Physical unclonable function; Elliptic curve cryptography; Performance evaluation; Internet of Things; Internet of Things; smart home; authentication; physical unclonable functions; ROR model; BAN logic; AVISPA | PROTOCOL; LIGHTWEIGHT; SYSTEM | authentication; AVISPA; BAN logic; Internet of Things; physical unclonable functions; ROR model; smart home | Authentication; Automation; Computation theory; Computer circuits; Intelligent buildings; Network security; Public key cryptography; Automated validation of internet security protocol and application; Burrow-abadi-needham logic; Home environment; Internet security; Random Model; Real-or-random model; Security application; Security protocols; Smart homes; User authentication scheme; Internet of things | English | 2022 | 2022 | 10.1109/access.2022.3208347 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Secure Batch Authentication Scheme for Multiaccess Edge Computing in 5G-Enabled Intelligent Transportation System | With the introduction of 5G technology in the intelligent transportation system (ITS), data bandwidth over communication channel is significantly increased. In the existing cloud-based ITS, a large-scale data is collected, stored, and analyzed to provide precise services to vehicle user, which creates a burden on the cloud service provider that can cause service delays or the inability to provide complex services. Multi-access edge computing (MEC) technology, which extends cloud capabilities to edge servers, is attracting attention in order to reduce the constraint of the cloud-based infrastructure. However, in ITS constructed on MEC, since vehicles exchange information through a wireless communication channel. It is vulnerable to various security attacks. This paper proposes a secure batch authentication scheme for multi-access edge computing in 5G-enabled ITS. The proposed scheme withstands common security attacks including impersonation, replay, man-in-the-middle, physical capture, offline password guessing attacks, and provides secure batch authentication, anonymity and confidentiality. We also consider the vehicle can cross the boundary between MEC servers for continuity of service. We analyze the security of the proposed scheme to show that the proposed scheme is secure against various security attacks, and performance analysis. Lastly, we conduct comparison with other related works. | Kim, Myeonghyun; Lee, Joonyoung; Oh, Jihyeon; Kwon, Deokkyu; Park, Kisung; Park, Youngho; Park, Kil Houm | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Blockchain Technol Res Ctr, Daejeon 34129, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Park, Kisung/KIG-3849-2024 | 57210278739; 57203970123; 57222066296; 57221739597; 57194833768; 56962990300; 35776805000 | parkyh@knu.ac.kr;khpark@ee.knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 0.97 | 2025-06-25 | 7 | 11 | Authentication; Servers; Security; Handover; Privacy; Wireless communication; Elliptic curve cryptography; Edge computing; Intelligent transportation systems; Multi-access edge computing; authentication and key agreement; intelligent transportation system; security | KEY AGREEMENT PROTOCOL; EFFICIENT; FRAMEWORK; VEHICLES | authentication and key agreement; intelligent transportation system; Multi-access edge computing; security | 5G mobile communication systems; Communication channels (information theory); Data privacy; Edge computing; Intelligent systems; Intelligent vehicle highway systems; Network security; Public key cryptography; Vehicle to Everything; Vehicle to vehicle communications; Vehicles; Authentication and key agreements; Curve cryptography; Edge computing; Elliptic curve; Elliptic curve cryptography; Hand over; Intelligent transportation systems; Multi-access edge computing; Multiaccess; Privacy; Security; Wireless communications; Authentication | English | 2022 | 2022 | 10.1109/access.2022.3205001 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Secure Three-Factor Authentication Protocol for E-Governance System Based on Multiserver Environments | In electronic governance (e-governance) system, citizens can access government services such as transportation, licensing and immigration remotely over the Internet. With the development of information and communication technology, usage of the e-governance system has been increased. To efficiently provide citizens with various e-governance services, multi-server environments can be applied to the e-governance system. However, messages can be inserted, deleted, and modified by a malicious adversary since these are transmitted through a public channel. Therefore, many researchers have suggested mutual authentication protocols for secure communication in multi-server environments. In 2020, Sudhakar et al. proposed a smart card based lightweight authentication protocol for multi-server environments. We analyze Sudhakar et al.'s protocol to propose a secure mutual authentication protocol in the e-governance system based on multi-server environments. However, we disclosure that their protocol is not resistant to smart card stolen, insider, man-in-the-middle, user impersonation, and session key disclosure attacks. Moreover, Sudhakar et al.'s protocol does not provide mutual authentication. To improve these security problems, we suggest a secure three-factor mutual authentication protocol for the e-governance system based on multi-server environments. We prove our protocol's security using informal security analysis, Burrows-Abadi-Needham (BAN) logic, and Real-or-Random (ROR) model. We also simulate our protocol utilizing Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. We estimate the proposed protocol's security functionalities, computation costs, and communication overheads compared with existing related protocols. Consequently, we demonstrate that our protocol is secure and suitable for the e-governance system. | Cho, Yeongjae; Oh, Jihyeon; Kwon, Deokkyu; Son, Seunghwan; Yu, Sungjin; Park, Yohan; Park, Youngho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Daejeon 34129, South Korea; Keimyung Univ, Sch Comp Engn, Daegu 42601, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57826219200; 57222066296; 57221739597; 57221744477; 57203974524; 55660095600; 56962990300 | parkyh@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 2.23 | 2025-06-25 | 21 | 26 | Protocols; Authentication; Security; Servers; Smart cards; Registers; Passwords; Electronic governance; multi-server; authentication; key agreement; fuzzy extractor; BAN logic; ROR model; AVISPA | KEY AGREEMENT PROTOCOL; USER AUTHENTICATION; PROVABLY SECURE; SCHEME; EXCHANGE; ANONYMITY; NETWORKS; INTERNET; SINGLE | authentication; AVISPA; BAN logic; Electronic governance; fuzzy extractor; key agreement; multi-server; ROR model | Computation theory; Computer circuits; Cryptography; Government data processing; Internet protocols; Network security; Smart cards; Automated validation of internet security protocol and application; Burrow-abadi-needham logic; Electronic governance; Fuzzy extractors; Internet security; Key agreement; Multiservers; Password; Random Model; Real-or-random model; Register; Security; Security application; Security protocols; Authentication | English | 2022 | 2022 | 10.1109/access.2022.3191419 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Assessment of carbon fibers recovered from lab-scale versus pilot-scale mechanochemical CFRP depolymerization process based on fastrack thermal oxidation-resistance characteristics | This study assessed the changes in the fiber properties of virgin and recovered fibers from lab-scale and pilot-scale depolymerization reactors based on the thermal air oxidation-resistance characteristics. Lab-scale and pilot-scale depolymerization reactors had different depolymerization volumes. Results showed that the lab-scale and pilot-scale peak solvent temperatures were 185 degrees C and 151 degrees C, respectively. The lab-scale had highest solvent temperature rate increase because of the small depolymerization volume and the dominant role of the cavitation volume. The structural properties of the recovered and virgin fibers were intact even after the depolymerization and after the pretreatment and oxidation-resistance test. We observed 1.213%, 1.027% and 0.842% weight loss for the recovered (lab-scale), the recovered (pilot-scale) and virgin fibers because of the removal of impurities from the surface and chemisorbed gases. Further, we observed 0.8% mass loss of the recovered fibers (lab-scale) after the oxidative-onset temperature because of the "cavitation erosion effect" from the dominant of the cavitation bubbles. The "cavitation erosion effect" was subdued because of the increased depolymerization volume in the pilot-scale reactor. Therefore, negligible impact of the pilot-scale mechanochemical recycling process on the structure and surface characteristics of the fibers and the possibility of reusing the recovered fibers recycling process were characteristic. Representative functional groups were affected by the thermal oxidation process. We conducted HPLC, HT-XRD, TGA-DSC, XPS, SEM, and AFM analysis and provided an extensive discussion of the test thereof. This study highlighted how misleading and insufficient small-lab-scale results could be in developing viable CFRP depolymerization process. | Yan, Caozheng; Njaramba, Lewis Kamande; Nzioka, Antony Mutua; Alunda, Benard Ouma; Kim, Myung-Gyun; Sim, Ye-Jin; Kim, Young-Ju | Hubei Univ Automot Technol, Sch Econ & Management, Chengcheng West Rd 167, Shiyan 442002, Peoples R China; Kyungpook Natl Univ, Coll Engn, Dept Environm Engn, Daehak Ro 80, Daegu 41566, South Korea; Silla Entech Co Ltd, R&D Inst, 559 Dalseo Daero, Daegu 42709, South Korea; Taita Taveta Univ, Dept Min & Mineral Proc, Voi, Kenya; Keimyung Coll Univ, Dept Fire & Environm Safety, Dalseo Daero 675, Daegu 42601, South Korea | ; Kamande, Lewis/JLL-5435-2023; Nzioka, Antony Mutua/Y-4112-2018 | 57191052533; 57223183206; 57191056730; 55354745500; 57191523939; 57203529016; 55699531200 | canozheg3101@outlook.com;lewiskamande@gmail.com;manymutua@naver.com;benard.ouma@ttu.ac.ke;episode07@naver.com;simyejin1582@naver.com;yjukim@knu.ac.kr; | CARBON LETTERS | CARBON LETT | 1976-4251 | 2233-4998 | 32 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 4.5 | 36.2 | 0.16 | 2025-06-25 | 2 | 2 | Carbon fibers; Mechanochemical recycling; Thermal oxidation resistance; CFRP; Weight loss; Surface characteristics | WASTE; KINETICS; XPS; AIR | Carbon fibers; CFRP; Mechanochemical recycling; Surface characteristics; Thermal oxidation resistance; Weight loss | Carbon fibers; Erosion; Oxidation resistance; Removal; Thermooxidation; Mechanochemical recycling; Mechanochemicals; Pilot scale; Recovered fiber; Resistance characteristics; Surface characteristics; Thermal oxidation resistance; Thermal-oxidation; Virgin fibers; Weight loss; Recycling | English | 2022 | 2022-06 | 10.1007/s42823-022-00343-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Attention-Based Multi-Learning Approach for Speech Emotion Recognition With Dilated Convolution | The success of deep learning in speech emotion recognition has led to its application in resource-constrained devices. It has been applied in human-to-machine interaction applications like social living assistance, authentication, health monitoring and alertness systems. In order to ensure a good user experience, robust, accurate and computationally efficient deep learning models are necessary. Recurrent neural networks (RNN) like long short-term memory (LSTM), gated recurrent units (GRU) and their variants that operate sequentially are often used to learn time series sequences of the signal, analyze long-term dependencies and the contexts of the utterances in the speech signal. However, due to their sequential operation, they encounter problems in convergence and sluggish training that uses a lot of memory resources and encounters the vanishing gradient problem. In addition, they do not consider spatial cues that may exist in the speech signal. Therefore, we propose an attention-based multi-learning model (ABMD) that uses residual dilated causal convolution (RDCC) blocks and dilated convolution (DC) layers with multi-head attention. The proposed ABMD model achieves comparable performance while taking global contextualized long-term dependencies between features in a parallel manner using a large receptive field with less increase in the number of parameters compared to the number of layers and considers spatial cues among the speech features. Spectral and voice quality features extracted from the raw speech signals are used as inputs. The proposed ABMD model obtained a recognition accuracy and F1 score of 93.75% and 92.50% on the SAVEE datasets, 85.89% and 85.34% on the RAVDESS datasets and 95.93% and 95.83% on the EMODB datasets. The model's robustness in terms of the confusion ratio of the individual discrete emotions especially happiness which is often confused with emotions that belong to the same dimensional plane with it also improved when validated on the same datasets. | Kakuba, Samuel; Poulose, Alwin; Han, Dong Seog | Kyungpook Natl Univ, Grad Sch Elect & Elect Engn, Daegu 41566, South Korea; Kabale Univ, Fac Engn Technol Appl Design & Fine Art, Kabale, Uganda; Univ Michigan, Dept Elect & Comp Engn, Dearborn, MI 48128 USA; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | POULOSE, ALWIN/S-4914-2018; Han, Dong Seog/N-8949-2018; Kakuba, Samuel/HLX-4856-2023; , ALWIN POULOSE/S-4914-2018 | 57988218000; 57205504085; 7403219442 | dshan@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2022 | 3.9 | 36.2 | 3.09 | 2025-06-25 | 26 | 36 | Computational modeling; Convolution; Feature extraction; Emotion recognition; Speech recognition; Deep learning; Task analysis; multi-head attention; residual dilated causal convolution | LSTM | Emotion recognition; multi-head attention; residual dilated causal convolution | Emotion Recognition; Job analysis; Long short-term memory; Speech communication; Speech recognition; Causal convolutions; Computational modelling; Deep learning; Emotion recognition; Features extraction; Learning models; Multi-head attention; Residual dilated causal convolution; Task analysis; Convolution | English | 2022 | 2022 | 10.1109/access.2022.3223705 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
