| ○ | ○ | Editorial Material | Revolutionizing scholarly publishing by integrating artificial intelligence into editorial and peer review processes | The advancement of artificial intelligence (AI) heralds an exciting era. A search for AI within the context of periodontics and implants reveals a plethora of scholarly articles. Similarly, an exploration of the Journal of Periodontal and Implant Science (JPIS) for research on AI uncovers significant findings in the fields of periodontics and implants [1-4]. It has been noted that AI can significantly aid in the diagnosis and prediction of periodontally compromised teeth [3]. Furthermore, AI has been used to identify different dental implant systems using panoramic radiographic images, achieving accuracy and performance comparable to that of boardcertified periodontists [4]. This suggests AI's potential as a valuable aid in diagnosis and decision-making [2]. Additionally, recent studies have emphasized the role of AI-powered chatbots in helping patients better understand their health conditions and make informed decisions [1]. | Park, Jun-Beom; Park, Shin -Young; Park, Jung-Chul; Kim, Yong-Gun; Ahn, Hwan Tae; Shin, Seung-Yun | Catholic Univ Korea, Coll Med, Dept Periodont, Seoul, South Korea; Seoul Natl Univ, Sch Dent, Dept Dent Sci, Seoul, South Korea; Seoul Natl Univ, Dent Res Inst, Sch Dent, Seoul, South Korea; Yonsei Goodday Dent Clin, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu, South Korea; JTS, Seoul, South Korea; Kyung Hee Univ, Dent Hosp, Coll Dent, Dept Periodontol, 26 Kyungheedae Ro, Seoul 02447, South Korea | ; Park, Jun-Beom/I-8201-2019; Park, Jc/AAB-3277-2021; Kim, Yong-Gun/JPQ-3309-2023 | 35084100800; 58092114800; 36612173800; 55622694400; 58958355500; 9279451200 | ssyislet@khu.ac.kr; | JOURNAL OF PERIODONTAL AND IMPLANT SCIENCE | J PERIODONTAL IMPLAN | 2093-2278 | 2093-2286 | 54 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 3.2 | 16.4 | 4.98 | 2025-05-07 | 1 | 1 | English | 2024 | 2024-04 | 10.5051/jpis.245402edi01 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | A posteriori error control for a discontinuous Galerkin approximation of a Keller-Segel model | We provide a posteriori error estimates for a discontinuous Galerkin scheme for the parabolic-elliptic Keller-Segel system in 2 or 3 space dimensions. The estimates are conditional in the sense that an a posteriori computable quantity needs to be small enough-which can be ensured by mesh refinement-and optimal in the sense that the error estimator decays with the same order as the error under mesh refinement. A specific feature of our error estimator is that it can be used to prove the existence of a weak solution up to a certain time based on numerical results. | Giesselmann, Jan; Kwon, Kiwoong | Tech Univ Darmstadt, Dept Math, Dolivostr 15, D-64293 Darmstadt, Germany; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | 33067816400; 58628537700 | jan.giesselmann@tu-darmstadt.de;kwkwon@knu.ac.kr; | ADVANCES IN COMPUTATIONAL MATHEMATICS | ADV COMPUT MATH | 1019-7168 | 1572-9044 | 50 | 6 | SCIE | MATHEMATICS, APPLIED | 2024 | 2.1 | 16.5 | 0 | 2025-05-07 | 0 | 0 | Keller-Segel; Chemotaxis; Diffusion; Discontinuous Galerkin scheme; A posteriori error analysis | FINITE-ELEMENT-METHOD; UPWIND SCHEME; CHEMOTAXIS; SYSTEM | A posteriori error analysis; Chemotaxis; Diffusion; Discontinuous Galerkin scheme; Keller-Segel | English | 2024 | 2024-12 | 10.1007/s10444-024-10212-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Reconstruction of the initial data from the trace of the solutions on an infinite time cylinder of damped wave equations | In this paper, we consider two types of damped wave equations: the weakly damped equation and the strongly damped equation. We recover the initial velocity from the trace of the solution on a space-time cylinder. This inverse problem is related to photoacoustic tomography (PAT), a hybrid medical imaging technique. PAT is based on generating acoustic waves inside of an object of interest and one of the mathematical problem in PAT is reconstructing the initial velocity from the solution of the wave equation measured on the outside of object. Using the spherical harmonics and spectral theorem, we demonstrate a way to recover the initial velocity. | Kim, Seongyeon; Moon, Sunghwan; Seo, Ihyeok | Jeonju Univ, Dept Math Educ, Jeonju 55069, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea; Sungkyunkwan Univ, SungKyunKwan Coll, Suwon 16419, South Korea | 57208903164; 56063426100; 35107985200 | sy_kim@jj.ac.kr;sunghwan.Moon@knu.ac.kr;ihseo@skku.edu; | INVERSE PROBLEMS | INVERSE PROBL | 0266-5611 | 1361-6420 | 40 | 6 | SCIE | MATHEMATICS, APPLIED;PHYSICS, MATHEMATICAL | 2024 | 2.1 | 16.5 | 0 | 2025-05-07 | 0 | 0 | wave equation; damping; reconstruction; photoacoustic | APPROXIMATION; STABILITY; OPERATOR | damping; photoacoustic; reconstruction; wave equation | Cylinders (shapes); Inverse problems; Medical imaging; Photoacoustic effect; Acoustics waves; Damped wave equations; Infinite time; Initial velocities; Mathematical problems; Medical imaging techniques; Photoacoustic tomography; Reconstruction; Spacetime; Spherical harmonics; Wave equations | English | 2024 | 2024-06-01 | 10.1088/1361-6420/ad42cd | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Laser-Induced One-Pot Deposition of Medium-Entropy Cocatalysts on Hematite Thin Films for Improved Photoelectrochemical Water Splitting | In this study, we integrate medium-entropy cocatalysts (MECs), composed of four elements-Fe, Ni, Co, and Cr-into nanostructured hematite (Fe2O3) thin films using a laser deposition process to enhance the photoelectrochemical (PEC) water splitting performance. The MEC-integrated hematite (MEC-Fe2O3) photoanodes exhibit remarkable improvements in water oxidation photocurrent, achieved through enhanced charge injection efficiency and a negatively shifted onset potential compared to bare Fe2O3. Multiphysics modeling elucidates the laser-induced MEC formation mechanism by estimating the temperature increase and changes in energy band structure and carrier concentrations. Furthermore, time-resolved photoluminescence (TRPL) studies unveil that the MEC layer extends the carrier lifetime of photogenerated charge carriers, leading to an overall enhancement in the efficiency of the water oxidation process. This work highlights the promising potential of laser-deposited MEC as a viable strategy to boost the efficiency of hematite photoanodes in PEC water splitting applications. | Ko, Seonmi; Kong, Heejung; Lee, Jehoon; Park, Hyo Jin; Kim, Hee Yeong; Park, Jucheol; Lee, Changwook; Chae, Weon-Sik; Yeo, Junyeob | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Helmholtz Zentrum Berlin Materialien & Energie Gmb, Inst Solar Fuels, Hahn Meitner Pl 1, D-14109 Berlin, Germany; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Gumi Elect & Informat Technol Res Inst, Gumi 39171, South Korea; Daegu Ctr, Korea Basic Sci Inst, Daegu 41566, South Korea | Yeo, Junyeob/I-1287-2013; Kong, Heejung/CAG-1032-2022 | 58110540600; 57552927300; 58150655100; 58997112400; 57777769800; 8733446100; 58996575600; 7003277427; 58692645200 | junyeob@knu.ac.kr; | ACS MATERIALS LETTERS | ACS MATER LETT | 2639-4979 | 6 | 10 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 8.7 | 16.6 | 0 | 2025-05-07 | 0 | 2 | PHOTOANODES; EVOLUTION; XPS | Carrier concentration; Hard facing; Hematite; Injection lasers; Photoluminescence; Co catalysts; Haematite; Laser depositions; Laser induced; Medium entropy; Nano-structured; One pot; Photoelectrochemical water splitting; Thin-films; Water oxidation; Carrier lifetime | English | 2024 | 2024-08-28 | 10.1021/acsmaterialslett.4c00704 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | An Ab Initio Study of the Origin of Structural Stability in P2-NaMnO2 with Li Doping at High Voltage | P2-type sodium cathode materials generally exhibit a P2-O2 phase transition upon deintercalation at high voltage, which is detrimental to their cycling performance. Herein, using first-principles calculations, we investigate the structural stability and phase transition of P2-Na0MnO2 upon substitution of Li for Mn as a model of a high-voltage phase. The phonon of P2-Na0MnO2 shows an imaginary phonon frequency, indicating instability, which is consistent with the experimental P2-O2 transformation. On the contrary, the phonon of P2-Na0Li0.25Mn0.75O2 shows dynamic stability. We demonstrate that the substitution of the Li ion induces the redistribution of charge from the out-of-plane to in-plane orbitals along with a reduced charge of oxygen. Furthermore, we consider the various Li doping compositions and suggest that the density of the next-nearest-neighbor Li-ion pairs also plays an important role in stabilizing the P2 phase. On the basis of our findings, we propose a minimum of similar to 20% Li doping to stabilize P2-NaLixMn1-xO2 at high voltage. | Kim, Heejung; Kim, Kyoo; Kim, Sooran | Pohang Univ Sci & Technol, Max Planck POSTECH Ctr Complex Phase Mat, Pohang 37673, South Korea; Korea Atom Energy Res Inst KAERI, Daejeon 43057, South Korea; Kyungpook Natl Univ, KNU Inst Basic Sci, KNU LAMP Res Ctr, Dept Phys Educ, Daegu 41566, South Korea | 56640022300; 57214859153; 55146733200 | sooran@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 15 | 5 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2024 | 4.6 | 16.7 | 0 | 2025-05-07 | 0 | 0 | NA-ION BATTERIES; TOTAL-ENERGY CALCULATIONS; OXIDE CATHODES; HIGH-CAPACITY; SODIUM; P2-TYPE; SUBSTITUTION; CHALLENGES; PHASE; HYSTERESIS | Lithium; Phonons; Stability; lithium ion; oxygen; Ab initio study; Cathodes material; Cycling performance; Deintercalation; First principle calculations; High-voltages; Li doping; O2-phase; Structural phasis; Structural stabilities; ab initio calculation; article; cathode electrode; controlled study; electric potential; normal human; phase transition; phonon; Cathodes | English | 2024 | 2024-01-29 | 10.1021/acs.jpclett.3c02540 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Bemarituzumab plus mFOLFOX6 as first-line treatment in East Asian patients with FGFR2b-overexpressing locally advanced or metastatic gastric/gastroesophageal junction cancer: subgroup of FIGHT final analysis | Background In the FIGHT study (NCT03694522) bemarituzumab, a humanized monoclonal antibody selective for fibroblast growth factor receptor 2b (FGFR2b), plus mFOLFOX6 showed clinically meaningful efficacy in patients with FGFR2b-positive (2+/3+ membranous staining by immunohistochemistry) locally advanced unresectable/metastatic gastric/gastroesophageal cancer (G/GEJC). A meaningful proportion of patients in FIGHT were enrolled in East Asia, reflecting global epidemiology of G/GEJC.Methods This subgroup analysis of the global, phase 2, double-blind FIGHT study included all patients enrolled in East Asian sites. Patients were randomized 1:1 to bemarituzumab-mFOLFOX6 (15 mg/kg and one 7.5 mg/kg dose on cycle 1, day 8) or matching placebo-mFOLFOX6. The primary endpoint was investigator-assessed progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate, and safety. Efficacy was evaluated after a minimum follow-up of 24 months.Results The East Asian subgroup comprised 89 patients (57% of overall study population); 45 were randomized to bemarituzumab-mFOLFOX6 and 44 to placebo-mFOLFOX6. Median PFS (95% confidence interval [CI]) was 12.9 months (8.8-17.9) with bemarituzumab-mFOLFOX6 and 8.2 months (5.6-10.3) with placebo-mFOLFOX6 (HR 0.50, 95% CI 0.29-0.87); median OS (95% CI) was 24.7 months (13.8-33.1) vs 12.9 months (9.3-21.4), respectively (HR 0.56, 95% CI 0.32-0.96). Treatment benefit was more pronounced in patients with FGFR2b-positive G/GEJC in >= 10% of tumor cells. No new safety signals were reported.Conclusion In East Asian patients with FGFR2b-positive advanced/metastatic G/GEJC enrolled in the global FIGHT study, bemarituzumab-mFOLFOX6 showed clinically meaningful outcomes over placebo-mFOLFOX6. | Kang, Yoon-Koo; Qin, Shukui; Lee, Keun-Wook; Oh, Sang Cheul; Kim, In-Ho; Kim, Jong Gwang; Li, Yong; Yan, Zhuchen; Li, Jin; Bai, Li-Yuan; Chan, Catherine; Yusuf, Akeem; Zahlten-Kuemeli, Anita; Taylor, Kate; Yamaguchi, Kensei | Univ Ulsan, Dept Oncol, Asan Med Ctr, Coll Med, 88 Olymp Ro 43-Gil, Seoul 05505, South Korea; China Pharmaceut Univ, Nanjing Tianyinshan Hosp, Affiliated Hosp 1, Nanjing, Peoples R China; Seoul Natl Univ, Bundang Hosp, Coll Med, Dept Ophthalmol, Seongnam, South Korea; Korea Univ, Guro Hosp, Dept Internal Med, Seoul, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Dept Oncol, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Daegu, South Korea; Hebei Med Univ, Dept Orthoped, Hosp 4, Shijiazhuang, Hebei, Peoples R China; Tianjin Med Univ, Canc Inst & Hosp, Tianjin, Peoples R China; Shanghai East Hosp, Dept Oncol, Shanghai, Peoples R China; China Med Univ Hosp, Div Hematol & Oncol, Taichung, Taiwan; Amgen Inc, Thousand Oaks, CA USA; Amgen Ltd, Uxbridge, England; JFCR, Gastroenterol Chemotherapy Dept, Canc Inst Hosp, Koto Ku, Tokyo, Japan | Kim, Sung-Bae/JXL-8219-2024; Lee, Juhyung/JQV-8143-2023; Kim, Jin Il/JWP-3629-2024; Kang, Yoon-Koo/ABL-4264-2022 | 7402784198; 57217457374; 35205887300; 55647062500; 55477690000; 59501049300; 59292233000; 56311518800; 59157671700; 7201957490; 59168569000; 55532479800; 57195437218; 59631165800; 12792930700 | ykkang@amc.seoul.kr; | GASTRIC CANCER | GASTRIC CANCER | 1436-3291 | 1436-3305 | 27 | 5 | SCIE | GASTROENTEROLOGY & HEPATOLOGY;ONCOLOGY | 2024 | 5.1 | 16.7 | 2.67 | 2025-05-07 | 6 | 6 | Bemarituzumab; FGFR2b; Gastric cancer; mFOLFOX6; Targeted therapy | CHEMOTHERAPY | Bemarituzumab; FGFR2b; Gastric cancer; mFOLFOX6; Targeted therapy | Adult; Aged; Aged, 80 and over; Antibodies, Monoclonal, Humanized; Antineoplastic Combined Chemotherapy Protocols; Asia, Eastern; Double-Blind Method; East Asian People; Esophageal Neoplasms; Esophagogastric Junction; Female; Fluorouracil; Folfox protocol; Humans; Leucovorin; Male; Middle Aged; Organoplatinum Compounds; Receptor, Fibroblast Growth Factor, Type 2; Stomach Neoplasms; Survival Rate; alanine; aspartate aminotransferase; bemarituzumab; fibroblast growth factor receptor 2; fibroblast growth factor receptor 2b; fluorouracil; folinic acid; immune checkpoint inhibitor; irinotecan; oxaliplatin; placebo; pyrimidine derivative; ramucirumab; taxane derivative; unclassified drug; antineoplastic agent; FGFR2 protein, human; fibroblast growth factor receptor 2; fluorouracil; folinic acid; monoclonal antibody; platinum complex; abdominal pain; adult; advanced cancer; aged; anemia; Article; constipation; controlled study; cornea disease; decreased appetite; diarrhea; double blind procedure; drug efficacy; drug fatality; drug safety; drug withdrawal; dry eye; East Asian; esophagus cancer; Far East; fatigue; female; fever; first-line treatment; follow up; gastroesophageal junction cancer; gastroesophageal junction cancer; human; hypertransaminasemia; immunohistochemistry; keratitis; leukopenia; limbal stem cell deficiency; major clinical study; male; metastatic gastroesophageal junction cancer; metastatic gastroesophageal junction cancer; metastatic stomach cancer; metastatic stomach cancer; nausea; neutropenia; outcome assessment; overall survival; phase 2 clinical trial; progression free survival; protein analysis; protein expression; punctate keratitis; randomized controlled trial; sensory neuropathy; stomach cancer; stomatitis; survival time; thrombocytopenia; treatment duration; treatment response; vomiting; clinical trial; drug therapy; esophagus tumor; gastroesophageal junction; middle aged; mortality; multicenter study; pathology; stomach tumor; survival rate; very elderly | English | 2024 | 2024-09 | 10.1007/s10120-024-01516-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Chemoexcited Formation and Radiationless Decay Dynamics of Firefly Chromophore | Multistate nonadiabatic dynamics combined with Mixed-Reference Spin-Flip Time-Dependent Density Functional Theory (MRSF-TDDFT) were performed to investigate the chemoexcitation dynamics of firefly dioxetanone (FDO- in S-0) to oxyluciferin (OxyLH(-) in S-1) and its subsequent decay dynamics. The formation of oxyluciferin occurs within approximately 100 fs and is primarily controlled by oscillatory CO2 decarboxylation. Unexpected radiationless decay from oxyluciferin was also observed, facilitated by intramolecular rotation. Simulations under three thermal conditions reveal that higher initial thermal energy not only enhances the formation of oxyluciferin but also increases radiationless decay by surpassing barriers to the ground state. Conversely, lower thermal energy conditions reduce oxyluciferin formation but suppress radiationless decay. These findings suggest that optimal conditions for higher chemiluminescence quantum yield involve initial high thermal energy to accelerate CO2 decarboxylation and gradual thermal dissipation to prevent intramolecular rotation of oxyluciferin. This approach could enhance the chemiluminescence quantum yield beyond the current limit of 40%, offering significant potential for applications in biological imaging and analytical chemistry. | Farmani, Maryam; Lee, Seunghoon; Zeng, Tao; Choi, Cheol Ho | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Seoul Natl Univ, Dept Chem, Seoul 151747, South Korea; York Univ, Dept Chem, Toronto, ON M3J 1P3, Canada | Lee, Seunghoon/AAB-4846-2021 | 58054703700; 57194591254; 58038551800; 7402958948 | tzeng@yorku.ca;cchoi@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 15 | 37 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2024 | 4.6 | 16.7 | 0.37 | 2025-05-07 | 1 | 1 | DENSITY-FUNCTIONAL THEORY; CHEMILUMINESCENT DECOMPOSITION; BIOLUMINESCENCE; MECHANISM; STATE; LUMINESCENCE; CHEMISTRY | Animals; Carbon Dioxide; Decarboxylation; Density Functional Theory; Fireflies; Heterocyclic Compounds, 1-Ring; Indoles; Luminescence; Pyrazines; Carbonylation; Carboxylation; Decay (organic); Quantum yield; Radiation chemistry; carbon dioxide; dioxetanone; indole derivative; oxyluciferin; pyrazine derivative; single heterocyclic rings; Decay dynamics; Energy; Energy condition; Multi-state; Non-adiabatic dynamics; Radiationless decay; Spin flip time; Thermal; Thermal condition; Time dependent density functional theory; animal; chemistry; decarboxylation; density functional theory; firefly; luminescence; Chemiluminescence | English | 2024 | 2024-09-11 | 10.1021/acs.jpclett.4c02227 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Clinical Usefulness of a Cell-based Assay for Detecting Myelin Oligodendrocyte Glycoprotein Antibodies in Central Nervous System Inflammatory Disorders | Background: The clinical implications of myelin oligodendrocyte glycoprotein autoantibodies (MOG-Abs) are increasing. Establishing MOG-Ab assays is essential for effectively treating patients with MOG-Abs. We established an in-house cell-based assay (CBA) to detect MOG-Abs to identify correlations with patients' clinical characteristics. Methods: We established the CBA using HEK 293 cells transiently overexpressing fulllength human MOG, tested it against 166 samples from a multicenter registry of central nervous system (CNS) inflammatory disorders, and compared the results with those of the Oxford MOG-Ab-based CBA and a commercial MOG-Ab CBA kit. We recruited additional patients with MOG-Abs and compared the clinical characteristics of MOG-Ab-associated disease (MOGAD) with those of neuromyelitis optica spectrum disorder (NMOSD). Results: Of 166 samples tested, 10 tested positive for MOG-Abs, with optic neuritis (ON) being the most common manifestation (4/15, 26.7%). The in-house and Oxford MOG-Ab CBAs agreed for 164/166 (98.8%) samples (kappa= 0.883, P < 0.001); two patients (2/166, 1.2%) were only positive in our in-house CBA, and the CBA scores of the two laboratories correlated well (r=0.663, P < 0.001). The commercial MOG-Ab CBA kit showed one false negative and three false-positive results. The clinical presentation at disease onset differed between MOGAD and NMOSD; ON was the most frequent manifestation in MOGAD, and transverse myelitis was most frequent in NMOSD. Conclusions: The in-house CBA for MOG-Abs demonstrated reliable results and can potentially be used to evaluate CNS inflammatory disorders. A comprehensive, long-term study with a large patient population would clarify the clinical significance of MOG-Abs. | Seok, Jin Myoung; Waters, Patrick; Jeon, Mi Young; Lee, Hye Lim; Baek, Seol-Hee; Park, Jin-Sung; Kang, Sa-Yoon; Kwon, Ohyun; Oh, Jeeyoung; Kim, Byung-Jo; Park, Kyung-Ah; Oh, Sei Yeul; Kim, Byoung Joon; Min, Ju-Hong | Soonchunhyang Univ, Coll Med, Dept Neurol, Hosp Cheonan, Cheonan, South Korea; Univ Oxford, John Radcliffe Hosp, Nuffield Dept Clin Neurosci, Oxford, England; Samsung Med Ctr, Neurosci Ctr, Dept Neurol, Seoul, South Korea; Korea Univ, Coll Med, Dept Neurol, Guro Hosp, Seoul, South Korea; Korea Univ, Anam Hosp, Coll Med, Dept Neurol, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Neurol, Daegu, South Korea; Jeju Natl Univ, Sch Med, Dept Neurol, Jeju, South Korea; Eulji Univ, Uijeongbu Eulji Med Ctr, Sch Med, Dept Neurol, Uijongbu, South Korea; Konkuk Univ, Med Ctr, Sch Med, Dept Neurol, Seoul, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Ophthalmol, Seoul, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Neurol, Seoul, South Korea; Sungkyunkwan Univ, Samsung Adv Inst Hlth Sci & Technol SAIHST, Dept Hlth Sci & Technol, Seoul, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Neurol, 81 Irwon Ro, Seoul 135710, South Korea | KWON, Ohyun/M-3231-2014; Kim, Byung-Jo/A-5943-2012 | 57197061814; 7102822799; 57226470512; 57202973906; 57164292800; 44061744500; 7405686930; 55713474800; 57193861769; 25626766200; 7408066565; 36128841900; 57210179291; 8235117900 | juhongm@skku.edu; | ANNALS OF LABORATORY MEDICINE | ANN LAB MED | 2234-3806 | 2234-3814 | 44 | 1 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2024 | 3.9 | 16.7 | 1.38 | 2025-04-16 | 3 | 3 | Autoantibody; Central nervous system disease; Immunoassay; Myelin oligo-dendrocyte glycoprotein | OPTICA SPECTRUM DISORDERS; DIAGNOSIS; DISEASE | Autoantibody; Central nervous system disease; Immunoassay; Myelin oligodendrocyte glycoprotein | Autoantibodies; Central Nervous System; Clinical Relevance; HEK293 Cells; Humans; Myelin-Oligodendrocyte Glycoprotein; autoantibody; myelin oligodendrocyte glycoprotein; central nervous system; clinical significance; clinical trial; HEK293S cell line; human; multicenter study | English | 2024 | 2024-01 | 10.3343/alm.2024.44.1.56 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Clonal Distribution and Its Association With the Carbapenem Resistance Mechanisms of Carbapenem-Non-Susceptible Pseudomonas aeruginosa Isolates From Korean Hospitals | Background: Carbapenem resistance in Pseudomonas aeruginosa is a serious global health problem. We investigated the clonal distribution and its association with the carbapenem resistance mechanisms of carbapenem-non-susceptible P. aeruginosa isolates from three Korean hospitals. Methods: A total of 155 carbapenem-non-susceptible P. aeruginosa isolates collected between 2011 and 2019 were analyzed for sequence types (STs), antimicrobial susceptibility, and carbapenem resistance mechanisms, including carbapenemase production, the presence of resistance genes, OprD mutations, and the hyperproduction of AmpC 13 -lactamase. Results: Sixty STs were identified in carbapenem-non-susceptible P. aeruginosa isolates. Two high -risk clones, ST235 (N =41) and ST111 (N =20), were predominant; however, sporadic STs were more prevalent than high -risk clones. The resistance rate to amikacin was the lowest (49.7%), whereas that to piperacillin was the highest (92.3%). Of the 155 carbapenem-non-susceptible isolates, 43 (27.7%) produced carbapenemases. Three metallo13 -lactamase (MBL) genes, bla IMP-6 (N =38), bla VIM-2 (N =3), and bla NDM-1 (N =2), were detected. bla IMP-6 was detected in clonal complex 235 isolates. Two ST773 isolates carried bla NDM-1 and rmtB. Frameshift mutations in oprD were identified in all isolates tested, regardless of the presence of MBL genes. Hyperproduction of AmpC was detected in MBL gene-negative isolates. Conclusions: Frameshift mutations in oprD combined with MBL production or hyperproduction of AmpC are responsible for carbapenem resistance in P. aeruginosa. Further attention is required to curb the emergence and spread of new carbapenem-resistant P. aeruginosa clones. | Kim, Nayeong; Ko, Seo Yeon; Park, Seong Yong; Kim, Seong Yeob; Lee, Da Eun; Kwon, Ki Tae; Kim, Yu Kyung; Lee, Je Chul | Kyungpook Natl Univ, Sch Med, Dept Microbiol, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Kyungpook Natl Univ Hosp Natl Culture Collect Path, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Lab Med, 130 Dongdeok Ro, Daegu 41944, South Korea | ; Kim, Hanjin/KYP-2633-2024; Kim, Young-Il/ISS-7678-2023 | 57211500281; 57959870800; 57958559800; 58290417200; 57224099074; 9733850500; 9237571900; 25930392000 | kimyg@knu.ac.kr;leejc@knu.ac.kr; | ANNALS OF LABORATORY MEDICINE | ANN LAB MED | 2234-3806 | 2234-3814 | 44 | 5 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2024 | 3.9 | 16.7 | 0.62 | 2025-05-07 | 2 | 1 | AmpC; Carbapenem resistance; Metallo-13-lactamase; OprD; Pseudomonas aeruginosa; Sequence type | RAPID DETECTION; ANTIMICROBIAL RESISTANCE; MOLECULAR EPIDEMIOLOGY; GENES; VIRULENCE; OPRD; CEPHALOSPORINASE; EMERGENCE; IMIPENEM; BACTERIA | AmpC; Carbapenem resistance; Metallo-β-lactamase; OprD; Pseudomonas aeruginosa; Sequence type | Anti-Bacterial Agents; Bacterial Proteins; beta-Lactamases; Carbapenems; Hospitals; Humans; Microbial Sensitivity Tests; Mutation; Porins; Pseudomonas aeruginosa; Pseudomonas Infections; Republic of Korea; AmpC beta-lactamases; antiinfective agent; bacterial protein; beta lactamase; carbapenem derivative; carbapenemase; OprD protein, Pseudomonas aeruginosa; porin; drug effect; genetics; hospital; human; isolation and purification; metabolism; microbial sensitivity test; microbiology; mutation; Pseudomonas aeruginosa; Pseudomonas infection; South Korea | English | 2024 | 2024-09 | 10.3343/alm.2023.0369 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Discrepant effect of high-density lipoprotein cholesterol on esophageal and gastric cancer risk in a nationwide cohort | Background The relationship between high-density lipoprotein cholesterol (HDL-C) and gastroesophageal cancer is not constant. Methods In this population-based cohort study, 4.518 million cancer-free individuals among those who underwent national cancer screening in 2010 were enrolled and followed up until December 2017. HDL-C level was classified into eight groups at 10 mg/dL intervals. The risk of gastroesophageal cancers by HDL-C was measured using adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). Results During 8 years of follow-up, 38,362 gastric and 3022 esophageal cancers developed. Low HDL-C level was associated with an increased risk of gastric cancer; aHR was 1.19 (95% CI 1.09-1.30) for HDL-C = 90 mg/dL. These site-specific effects of HDL-C were robust in sensitivity analyses. The range of HDL-C for the lowest cancer risk was different by sex and site. The hazardous effect of low HDL-C on gastric cancer was prominent in never and past smokers, and extremely high HDL-C increased gastric cancer risk (aHR 1.19; 95% CI 1.04-1.36) only in current smokers. Unfavorable effect of high HDL-C on gastroesophageal cancer risk was remarkable in smokers. Conclusions Low HDL-C increased the risk of gastric cancer, wherein high HDL-C was associated with esophageal cancer risk with discrepancies by sex and smoking status. | Nam, Su Youn; Jo, Junwoo; Jeon, Seong Woo | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Gastroenterol, 807 Hoguk, Daegu 702210, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea | Jeon, Seongwoo/AAU-4618-2020 | 55617028500; 57210425017; 9733636500 | nam20131114@gmail.com; | GASTRIC CANCER | GASTRIC CANCER | 1436-3291 | 1436-3305 | 27 | 3 | SCIE | GASTROENTEROLOGY & HEPATOLOGY;ONCOLOGY | 2024 | 5.1 | 16.7 | 2.13 | 2025-05-07 | 4 | 4 | Gastric cancer; Esophageal cancer; High-density lipoprotein cholesterol; Sex; Smoking status | BREAST-CANCER; SERUM; ASSOCIATION; HDL | Esophageal cancer; Gastric cancer; High-density lipoprotein cholesterol; Sex; Smoking status | Cholesterol, HDL; Cohort Studies; Esophageal Neoplasms; Humans; Risk; Risk Factors; Stomach Neoplasms; high density lipoprotein cholesterol; high density lipoprotein cholesterol; adult; Article; cancer free survival; cancer localization; cancer risk; cancer screening; cohort analysis; confidence interval; controlled study; esophagus cancer; female; follow up; hazard ratio; human; major clinical study; male; menopause; middle aged; people by smoking status; sensitivity analysis; sex; smoking; stomach cancer; esophagus tumor; risk; risk factor; stomach tumor | English | 2024 | 2024-05 | 10.1007/s10120-024-01477-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Enhanced thermoelectric performance of NbCoSb half-Heusler alloys by using an amorphous precursor | Amorphous flakes with a stoichiometric composition of NbCoSb were successfully synthesized by introducing a rapid solidification technique. The amorphous phase transformed into a nanostructured NbCoSb half-Heusler phase with a valence electron count (VEC) of 19 during spark plasma sintering. Due to the chemically homogeneous nature of amorphous phase, uniform nanostructure of NbCoSb half-Heusler phase was obtained within the disk samples without impurity phase formation as well as long term annealing treatment required in the conventional manufacturing process. Nanostructuring of NbCoSb half-Heusler phase significantly increased grain boundary area in which electron and phonon scattering occurred and was effective to enhance thermoelectric performance. Furthermore, the carrier concentration was reduced by doping with Sn causing an increased dimensionless figure-of-merit ZT value. A maximum ZT value of -0.78, corresponding to a two-fold improvement compared to the ZT value of the as-cast sample, was achieved at 1173 K for the sintered NbCoSb0.95Sn0.05 sample. | Oh, Jaeyoung; Lee, Ho Seong; Yi, Seonghoon | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea | Yi, Seonghoon/HGC-6912-2022 | 58419757100; 55706810400; 14008383000 | yish@knu.ac.kr; | JOURNAL OF NON-CRYSTALLINE SOLIDS | J NON-CRYST SOLIDS | 0022-3093 | 1873-4812 | 624 | SCIE | MATERIALS SCIENCE, CERAMICS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.5 | 16.7 | 1.65 | 2025-05-07 | 5 | 5 | Amorphous; Half-Heusler; Nanostructure; Thermoelectric; Phonon scattering | PHASE; SOLUBILITY | Amorphous; Half-Heusler; Nanostructure; Phonon scattering; Thermoelectric | Carrier concentration; Cobalt alloys; Grain boundaries; Nanostructures; Phonons; Rapid solidification; Spark plasma sintering; Thermoelectricity; Amorphous phasis; Amorphous precursors; Half-heusler; Half-Heusler alloys; Heusler phasis; Rapid solidification techniques; Stoichiometric compositions; Synthesised; Thermoelectric; Thermoelectric performance; Phonon scattering | English | 2024 | 2024-01-15 | 10.1016/j.jnoncrysol.2023.122729 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Feasibility of intraoperative pathologic examination for sentinel lymph nodes during sentinel node navigation surgery in early gastric cancer: results of pathologic protocol for SENORITA trial | BackgroundDuring sentinel node navigation surgery in patients with gastric cancer, intraoperative pathologic examination of sentinel nodes is crucial in determining the extent of surgery. In this study, we evaluated the feasibility and accuracy of intraoperative pathologic protocols using data from a prospective, multicenter, randomized trial.MethodsA retrospective analysis was conducted using data from the SEntinel Node ORIented Tailored Approach trials from 2013 to 2016. All sentinel lymph nodes were evaluated during surgery with hematoxylin-eosin (HE) staining using a representative section at the largest plane for lymph nodes. For permanent histologic evaluation, sentinel basin nodes were stained with HE and cytokeratin immunohistochemistry in formalin-fixed, paraffin-embedded (FFPE) sections and examined with HE for three deeper-step sections at 200-mu m intervals. The failure rate of identification by frozen section and the metastasis rate in non-sentinel basins were investigated.ResultsOf the 237 patients who underwent sentinel node basin dissection, 30 had lymph node metastases on permanent pathology. Thirteen patients had macrometastasis confirmed in frozen sections as well as FFPE sections (failure rate: 0%). Patients with negative sentinel nodes in frozen sections but micrometastasis in FFPE sections had no lymph node recurrence during the follow-up period (0%, 0/6). However, in cases with tumor-positive nodes in frozen sections, metastases in non-sentinel basins were detected in the paraffin blocks (8.3%, 2/24).ConclusionsThe single-section HE staining method is sufficient for detecting macrometastasis via intraoperative pathological examination. If a negative frozen-section result is confirmed, sentinel basin dissection can be performed safely. Otherwise, standard surgery is required. | Park, Sin Hye; Chung, Soo Young; Lee, Jeong-Hee; Kim, Hee Kyung; Lee, Dakeun; Kim, Hyunki; Kim, Jo-Heon; Kim, Min Seok; Lee, Jae Hyuk; Park, Ji Yeon; Yoon, Hong Man; Ryu, Keun Won; Kook, Myeong-Cherl | Natl Canc Ctr, Ctr Gastr Canc, Ilsan Ro 323, Goyang Si 10408, South Korea; Catholic Univ Korea, Eunpyeong St Marys Hosp, Dept Surg, Seoul, South Korea; Dongnam Inst Radiol & Med Sci DIRAMS, Ctr Canc, Dept Pathol, Busan, South Korea; Gyeongsang Natl Univ, Gyeongsang Natl Univ Hosp, Inst Hlth Sci, Dept Pathol,Coll Med, Jinju, South Korea; Soon Chun Hyang Univ, Bucheon Hosp, Dept Pathol, Bucheon, South Korea; Ajou Univ, Sch Med, Dept Pathol, Suwon, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Pathol, Seoul, South Korea; Chonnam Natl Univ, Med Sch, Dept Pathol, Hwasun Hosp, Hwasun, South Korea; Chonnam Natl Univ, Med Sch, Dept Pathol, Gwangju, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Surg, Daegu, South Korea | ; Kim, Soo-Yeon/ADR-9663-2022; Park, Ji Yeon/AAV-2471-2020; Lee, Jae-Yeong/AEP-9607-2022; Lee, Jae-Young/GWZ-2558-2022; Kim, Seong/J-5408-2012 | 54414695000; 55668044100; 55279997100; 56714172200; 13005894800; 56984410700; 23667649700; 58997471200; 57205336078; 57196405216; 35735626600; 55667555300; 7003734725 | mckook@ncc.re.kr; | GASTRIC CANCER | GASTRIC CANCER | 1436-3291 | 1436-3305 | 27 | 4 | SCIE | GASTROENTEROLOGY & HEPATOLOGY;ONCOLOGY | 2024 | 5.1 | 16.7 | 0.53 | 2025-05-07 | 2 | 3 | Stomach neoplasm; Sentinel lymph node; Frozen section; Lymph node metastasis; Early gastric cancer | MICROSATELLITE INSTABILITY; PLUS CHEMOTHERAPY; DEFICIENCY; GUIDELINE; SURVIVAL; TUMORS | Early gastric cancer; Frozen section; Lymph node metastasis; Sentinel lymph node; Stomach neoplasm | Adult; Aged; Aged, 80 and over; Feasibility Studies; Female; Frozen Sections; Gastrectomy; Humans; Lymph Node Excision; Lymphatic Metastasis; Male; Middle Aged; Prospective Studies; Retrospective Studies; Sentinel Lymph Node; Sentinel Lymph Node Biopsy; Stomach Neoplasms; antineoplastic agent; adult; aged; Article; cancer adjuvant therapy; cancer incidence; clinical article; controlled study; diagnostic accuracy; early cancer; feasibility study; female; follow up; frozen section; histopathology; human; human tissue; intraoperative period; laparoscopic distal gastrectomy; laparoscopic pylorus preserving gastrectomy; laparoscopic surgery; laparoscopic total gastrectomy; lymph node dissection; lymph node metastasis; male; micrometastasis; middle aged; retrospective study; segmentectomy; sentinel lymph node; sentinel lymph node metastasis; stomach cancer; wedge resection; clinical trial; feasibility study; gastrectomy; lymph node dissection; lymph node metastasis; multicenter study; pathology; procedures; prospective study; randomized controlled trial; sentinel lymph node biopsy; stomach tumor; surgery; very elderly | English | 2024 | 2024-07 | 10.1007/s10120-024-01497-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Harnessing exosomes as cancer biomarkers in clinical oncology | Exosomes are extracellular vesicles well known for facilitating cell-to-cell communication by distributing essential macromolecules like proteins, DNA, mRNA, lipids, and miRNA. These vesicles are abundant in fluids distributed throughout the body, including urine, blood, saliva, and even bile. They are important diagnostic tools for breast, lung, gastrointestinal cancers, etc. However, their application as cancer biomarkers has not yet been implemented in most parts of the world. In this review, we discuss how OMICs profiling of exosomes can be practiced by substituting traditional imaging or biopsy methods for cancer detection. Previous methods like extensive imaging and biopsy used for screening were expensive, mostly invasive, and could not easily provide early detection for various types of cancer. Exosomal biomarkers can be utilized for routine screening by simply collecting body fluids from the individual. We anticipate that the use of exosomes will be brought to light by the success of clinical trials investigating their potential to enhance cancer detection and treatment in the upcoming years. | Ghosh, Subhrojyoti; Rajendran, Ramya Lakshmi; Mahajan, Atharva A.; Chowdhury, Ankita; Bera, Aishi; Guha, Sudeepta; Chakraborty, Kashmira; Chowdhury, Rajanyaa; Paul, Aritra; Jha, Shreya; Dey, Anuvab; Dubey, Amit; Gorai, Sukhamoy; Das, Purbasha; Hong, Chae Moon; Krishnan, Anand; Gangadaran, Prakash; Ahn, Byeong-Cheol | Indian Inst Technol Madras, Dept Biotechnol, Chennai 600036, India; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu 41944, South Korea; Adv Ctr Treatment Res & Educ Canc ACTREC, Navi Mumbai 410210, India; Indian Inst Technol, Dept Biochem Engn & Biotechnol, Delhi 110016, India; Heritage Inst Technol, Dept Biotechnol, Kolkata 700107, India; Indian Inst Technol Indian Sch Mines, Dept Chem & Chem Biol, Dhanbad 826004, Jharkhand, India; Natl Inst Technol, Dept Biomed Engn, Rourkela 769008, Orissa, India; Indian Inst Technol, Dept Biosci & Bioengn, Gauhati 781039, Assam, India; Quanta Calculus, Computat Chem & Drug Discovery Div, Greater Noida, Uttar Pradesh, India; Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Pharmacol, Chennai, Tamil Nadu, India; Rush Univ, Med Ctr, Dept Neurol Sci, Chicago, IL USA; Presidency Univ, Dept Life Sci, Kolkata 700073, West Bengal, India; Kyungpook Natl Univ, Dept Nucl Med, Daegu 41944, South Korea; Univ Free State, Fac Hlth Sci, Sch Pathol, Dept Chem Pathol, ZA-9300 Bloemfontein, South Africa; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 FOUR KNU Convergence Educ Program Biomed Sci, Daegu 41944, South Korea | ; Dubey, Amit/AEK-6447-2022; DEY, ANUVAB/HSI-3094-2023; Rajendran, Ramya/AAV-6338-2021; Gorai, Sukhamoy/ISV-0641-2023; Ghosh, Subhrojyoti/KDN-2006-2024; Gangadaran, Prakash/AAV-3102-2021; Krishnan, Anand/C-5178-2015 | 58035427200; 57195318729; 58653487800; 58665538700; 58563528700; 58563497900; 58563528800; 58665931400; 58622204400; 58127305100; 57225769107; 57185007400; 37049892200; 59250676900; 37050876700; 57488883300; 54393130400; 7202791511 | krishnana1@ufs.ac.za;prakashg@knu.ac.kr;abc2000@knu.ac.kr; | CANCER CELL INTERNATIONAL | CANCER CELL INT | 1475-2867 | 24 | 1 | SCIE | ONCOLOGY | 2024 | 6 | 16.7 | 2.66 | 2025-05-07 | 17 | 16 | Exosomes; Cancer biomarkers; Clinical signature; Diagnostic tool; Prognostic indicator; Tumor-derived exosomes; Molecular profiling; Cancer diagnosis | ENHANCED RAMAN-SPECTROSCOPY; CELL-DERIVED EXOSOMES; EXTRACELLULAR VESICLES; MEDIATED TRANSFER; INTERCELLULAR TRANSFER; LIQUID BIOPSIES; SERUM EXOSOMES; MICROVESICLES; MICRORNAS; PROMOTES | Cancer biomarkers; Cancer diagnosis; Clinical signature; Diagnostic tool; Exosomes; Molecular profiling; Prognostic indicator; Tumor-derived exosomes | biological marker; DNA; lipid; messenger RNA; microRNA; tumor marker; bile; body fluid; cancer diagnosis; cell communication; diagnosis; diagnostic test accuracy study; exosome; gastrointestinal cancer; hematuria; human; macromolecule; malignant neoplasm; molecular fingerprinting; review; saliva | English | 2024 | 2024-08-07 | 10.1186/s12935-024-03464-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Hf0.4Zr0.6O2 Thickness-Dependent Transfer Characteristics of In x Zn1-x O y Channel Ferroelectric FETs | We investigate how the threshold voltage (V-T) is adjusted to create a memory window (MW) in ferroelectric field-effect transistors (FeFETs) composed of ferroelectric Hf0.4Zr0.6O2 and InZnO (In2O3:ZnO = 9:1 wt %). Temperature-dependent polarization measurements reveal a dipole switching in Hf0.4Zr0.6O2. The properties of the n-type InZnO channel are examined by fabricating an oxide transistor with an HfO2 gate dielectric. Upon replacement of HfO2 with Hf0.4Zr0.6O2 in the oxide transistor, a counterclockwise MW is observed. Specifically, as the Hf0.4Zr0.6O2 thickness increases from 16 to 24 nm, the V-T of the FeFET after a + gate voltage (V-G) sweep remains nearly constant, while the V-T after a -V-G sweep shifts significantly from -0.9 to 0.5 V. The enlarged MW of approximately 2 V, which is proportional to the Hf0.4Zr0.6O2 thickness in the FeFET, can be explained by considering the balance between V-G controllability across the gate stack and the ferroelectric switching of Hf0.4Zr0.6O2. | Jeong, Jiae; Park, Hyoungjin; Kim, Jihyun; Moon, Hojin; Choi, Hyeonsik; Kim, Eunjin; Jeon, Seonuk; Kim, Yunsur; Woo, Jiyong | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 58963433800; 58964076600; 59361845100; 59362010600; 58835686900; 57222322113; 57955098300; 58847712800; 53985749100 | jiyong.woo@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 15 | 40 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2024 | 4.6 | 16.7 | 0 | 2025-05-07 | 0 | 0 | DEVICES | Ferroelectric ceramics; Ferroelectric RAM; Field effect transistors; Gallium compounds; Gate dielectrics; Hafnium oxides; Semiconducting indium phosphide; Surface discharges; Ferroelectric fieldeffect transistors (FeFET); HfO 2; Memory window; Oxide transistors; Polarization measurements; Temperature dependent; Transfer characteristics; Voltage sweep; Y channels; ZnO; animal tissue; article; controlled study; dipole; electric potential; female; field effect transistor; male; nonhuman; polarization; temperature; thickness; transistor; Zinc oxide | English | 2024 | 2024-10-03 | 10.1021/acs.jpclett.4c02201 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Machine Learning Prediction Models for Solid Electrolytes Based on Lattice Dynamics Properties | Recently, machine-learning approaches have accelerated computational materials design and the search for advanced solid electrolytes. However, the predictors are currently limited to static structural parameters, which may not fully account for the dynamic nature of ionic transport. In this study, we meticulously curated features considering dynamic properties and developed machine-learning models to predict the ionic conductivity, sigma, of solid electrolytes. We compiled 14 phonon-related descriptors from first-principles phonon calculations along with 16 descriptors related to the structure and electronic properties. Our logistic regression classifiers exhibit an accuracy of 93%, while the random forest regression model yields a root-mean-square error for log(sigma) of 1.179 S/cm and R-2 of 0.710. Notably, phonon-related features are essential for estimating the ionic conductivities in both models. Furthermore, we applied our prediction model to screen 264 Li-containing materials and identified 11 promising candidates as potential superionic conductors. | Kim, Jiyeon; Lee, Donggeon; Lee, Dongwoo; Li, Xin; Lee, Yea-Lee; Kim, Sooran | Kyungpook Natl Univ, Dept Phys Educ, Daegu 41566, South Korea; Kyungpook Natl Univ, Ctr High Energy Phys, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Sungkyunkwan Univ, SKKU Adv Inst Nanotechnol SAINT, Suwon 16419, South Korea; Sungkyunkwan Univ, Dept Nano Engn, Suwon 16419, South Korea; Sungkyunkwan Univ, Sch Mech Engn, Suwon 16419, South Korea; Harvard Univ, John A Paulson Sch Engn & Appl Sci, Cambridge, MA 02138 USA; Korea Res Inst Chem Technol, Chem Data Driven Res Ctr, Daejeon 34114, South Korea; Kyungpook Natl Univ, KNU Inst Basic Sci, KNU G LAMP Project Grp, Daegu 41566, South Korea | ; Lee, Dongwoo/AAE-2099-2022 | 57456694400; 57199466655; 55960626200; 57209057218; 35790936100; 55146733200 | sooran@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 15 | 22 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2024 | 4.6 | 16.7 | 0 | 2025-05-07 | 2 | 3 | TOTAL-ENERGY CALCULATIONS; STRUCTURE DATABASE ICSD; HIGH IONIC-CONDUCTIVITY; LI-ION; CRYSTAL-STRUCTURE; STATE ELECTROLYTES; LITHIUM; BATTERY; CONDUCTORS; DIFFUSION | Crystal lattices; Elastic moduli; Electronic properties; Forecasting; Forestry; Ionic conduction in solids; Ionic conductivity; Ions; Machine learning; Mean square error; Phonons; Regression analysis; electrolyte; Computational material designs; Descriptors; Dynamic nature; Dynamics properties; Ionic transports; Machine learning approaches; Machine learning models; Machine-learning; Prediction modelling; Structural parameter; article; classifier; conductance; conductor; human; ion transport; ionization; logistic regression analysis; machine learning; phonon; prediction; random forest; regression model; root mean squared error; solid; Solid electrolytes | English | 2024 | 2024-05-29 | 10.1021/acs.jpclett.4c00995 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
