○ ○ Article ⓘ Durvalumab with or without bevacizumab with transarterial chemoembolisation in hepatocellular carcinoma (EMERALD-1): a multiregional, randomised, double-blind, placebo-controlled, phase 3 study ⓘ Background Transarterial chemoembolisation (TACE) is standard of care for patients with unresectable hepatocellular carcinoma that is amenable to embolisation; however, median progression-free survival is still approximately 7 months. We aimed to assess whether adding durvalumab, with or without bevacizumab, might improve progression-free survival. Methods In this multiregional, randomised, double-blind, placebo-controlled, phase 3 study (EMERALD-1), adults aged 18 years or older with unresectable hepatocellular carcinoma amenable to embolisation, an Eastern Cooperative Oncology Group performance status of 0 or 1 at enrolment, and at least one measurable intrahepatic lesion per modified Response Evaluation Criteria in Solid Tumours (RECIST) were enrolled at 157 medical sites including research centres and general and specialist hospitals in 18 countries. Eligible patients were randomly assigned (1:1:1), stratified by TACE method, region, and portal vein invasion, using an interactive voice response or web response system, to TACE plus either durvalumab plus bevacizumab (1500 mg intravenous durvalumab once every 4 weeks, then 1120 mg durvalumab plus 15 mg/kg intravenous bevacizumab once every 3 weeks), durvalumab plus placebo (same regimen using placebo instead of bevacizumab), or placebo alone (same regimen using placebo instead of durvalumab and instead of bevacizumab). Participants, investigators, and those assessing outcomes were masked to treatment assignment until data analysis. The primary endpoint was progression-free survival, by blinded independent central review (BICR), and per RECIST version 1.1, with durvalumab plus bevacizumab versus placebo alone in the intention-to-treat population (ITT; ie, all participants assigned to treatment). Key secondary endpoints were progression-free survival by BICR per RECIST version 1.1 with durvalumab plus placebo versus placebo alone, overall survival, and time to deterioration in select patient-reported outcomes. Participants continue to be followed up for overall survival, and overall survival and patient-reported outcomes will be reported in a later publication. Safety was assessed in the safety analysis set, which included all participants assigned to treatment who received any study treatment (ie, any durvalumab, bevacizumab, or placebo) by treatment received. This study is registered with ClinicalTrials.gov, NCT03778957, and is closed to accrual. Findings Between Nov 30, 2018, and July 19, 2021, 887 patients were screened, of whom 616 were randomly assigned to durvalumab plus bevacizumab (n=204), durvalumab plus placebo (n=207), or placebo alone (n=205; ITT population). Median age was 650 years (IQR 590-720), 135 (22%) of 616 participants were female, 481 (78%) were male, 375 (61%) were Asian, 176 (29%) were White, 22 (4%) were American Indian or Alaska Native, nine (1%) were Black or African American, one (9 months (95% CI 274-304), median progression-free survival was 150 months (95% CI 111-189) with durvalumab plus bevacizumab, 100 months (90-127) with durvalumab, and 82 months (69-111) with placebo. Progression-free survival hazard ratio was 077 (95% CI 061-098; two-sided p=0032) for durvalumab plus bevacizumab versus placebo, and 094 (075-119; two-sided p=064) for durvalumab plus placebo versus placebo. The most common maximum grade 3-4 adverse events were hypertension in participants who received durvalumab and bevacizumab (nine [6%] of 154 participants), anaemia in participants who received durvalumab and placebo (ten [4%] of 232 participants), and post-embolisation syndrome in participants who received placebo alone (eight [4%] of 200 participants). Study treatment-related adverse events that led to death occurred in none of 154 participants who received durvalumab and bevacizumab, three (1%) of 232 who received durvalumab and placebo (n=1 for arterial haemorrhage, liver injury, and multiple organ dysfunction syndrome), and three (2%) of 200 who received placebo alone (n=1 for oesophageal varices haemorrhage, upper gastrointestinal haemorrhage, and dermatomyositis). Interpretation Durvalumab plus bevacizumab plus TACE has the potential to set a new standard of care. With additional follow-up of the EMERALD-1 study, future analyses, including the final overall survival data and patient-reported outcomes, will help to further characterise the potential clinical benefits of durvalumab plus bevacizumab plus TACE in hepatocellular carcinoma amenable to embolisation. ⓘ Sangro, Bruno;

○ ○ Article ⓘ Safety and efficacy of nipocalimab in adults with generalised myasthenia gravis (Vivacity-MG3): a phase 3, randomised double-blind, placebo-controlled study ⓘ Background Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study. Methods Vivacity-MG3 was a phase 3, randomised, double-blind, placebo-controlled, phase 3 study conducted at 81 outpatient centres with expertise in myasthenia gravis in 17 countries in Asia-Pacific, Europe, and North America. Adults (aged >= 18 years) with generalised myasthenia gravis inadequately controlled with standard-of-care therapy (MG-ADL score >= 6) were randomly assigned (1:1) to either nipocalimab (30 mg/kg loading dose then 15 mg/kg every 2 weeks for maintenance dosing) or placebo infusions every 2 weeks, added to standard-of-care therapy in both groups, for 24 weeks. Randomisation was stratified by antibody status, day 1 MG-ADL total score, and region. The sponsor, investigators, clinical raters, and participants were masked to treatment assignment. The primary endpoint was the difference between nipocalimab and placebo based on least-squares mean change from baseline in MG-ADL total score averaged over weeks 22, 23, and 24 in the intention-to-treat population of patients who were antibody- positive (for AChR, anti-muscle-specific tyrosine kinase [MuSK], or anti-low-density lipoprotein receptor-related protein 4 [LRP4]). Adverse events were assessed in patients who received at least one dose of study drug. This study is registered at ClinicalTrials.gov, NCT04951622; the double-blind phase is completed and an open-label extension phase is ongoing. Findings Between July 15, 2021, and Nov 17, 2023, 199 patients were enrolled, and 196 patients received study drug (98 in the nipocalimab group and 98 in the placebo group); of these, 153 (77 in the nipocalimab group and 76 in the placebo group) were antibody-positive. The least-squares mean change in MG-ADL score from baseline to weeks 22, 23, and 24 was -470 (SE 0329) in the nipocalimab group versus -325 (0335) in the placebo group (difference -145 [95% CI -238 to -052]; p=00024). The incidence of adverse events was similar between groups (82 [84%] of 98 in both the nipocalimab and placebo groups), including infections (42 [43%] of 98 in the nipocalimab group and placebo group) and headache (14 [14%] of 98 in the nipocalimab group and 17 [17%] of 98 in the placebo group). Serious adverse events were reported for nine (9%) of 98 patients in the nipocalimab group and 14 (14%) of 98 patients in the placebo group, three of which had a fatal outcome (nipocalimab: myasthenic crisis; placebo: cardiac arrest and myocardial infarction). Interpretation Results from the completed double-blind phase of Vivacity-MG3 support the role of nipocalimab, added to standard-of-care therapies, as a safe treatment for sustained disease control over 6 months for a broad population of patients with generalised myasthenia gravis who are antibody-positive. The ongoing open-label extension phase should provide longer term sustained safety and efficacy data with nipocalimab. ⓘ Antozzi, Carlo; Vu, Tuan; Ramchandren, Sindhu; Nowak, Richard J.; Farmakidis, Constantine; Bril, Vera; De Bleecker, Jan; Yang, Huan; Minks, Eduard; Park, Jin-Sung; Grudniak, Mariusz; Smilowski, Marek; Sevilla, Teresa; Hoffmann, Sarah; Sivakumar, Kumaraswamy; Suzuki, Yasushi; Youssef, Eriene; Sanga, Panna; Karcher, Keith; Zhu, Yaowei; Sheehan, John J.; Sun, Hong ⓘ Fdn IRCCS Carlo Besta Neurol Inst, Neuromuscular Dis & Neuroimmunol Unit, Milan, Italy; IRCCS Carlo Besta Neurol Inst Fdn, Apheresis & Immunotherapy Unit, Milan, Italy; Univ South Florida Hlth, Morsani Coll Med, Dept Neurol, Tampa, FL USA; Janssen Res & Dev, Titusville, NJ 08560 USA; Yale Univ, Sch Med, Dept Neurol, New Haven, CT USA; Univ Kansas, Med Ctr, Dept Neurol, Kansas City, KS USA; Univ Toronto, Univ Hlth Network, Dept Med, Toronto, ON, Canada; Ghent Univ Hosp, Dept Neurol, Ghent, Belgium; Cent South Univ, Xiangya Hosp, Dept Neurol, Changsha, Hunan, Peoples R China; Masaryk Univ, Dept Neurol, Brno, Czech Republic; St Annes Hosp, Brno, Czech Republic; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Neurol, Daegu, South Korea; Ctr Med NeuroProtect, Warsaw, Poland; Upper Silesian Med Ctr, Katowice, Poland; Hosp Univ & Politecn, Dept Hematol & Med Oncol, Valencia, Spain; IIS La Fe, Valencia, Spain; Univ Valencia, Valencia, Spain; Charite, Neurosci Clin Res Ctr NCRC, Dept Neurol, Berlin, Germany; Charite, Integrated Myasthenia Gravis Ctr, Berlin, Germany; Free Univ Berlin, Berlin, Germany; Humboldt Univ, Berlin, Germany; Neuromuscular Res Ctr, Phoenix, AZ 85028 USA; Neuromuscular Clin Arizona, Phoenix, AZ USA; Natl Hosp Org, Sendai Med Ctr, Sendai, Japan; Janssen Res & Dev, Stat & Decis Sci, Titusville, NJ 08560 USA; Janssen Global Serv, Global Med Affairs, Raritan, NJ USA ⓘ ; Hoffmann, Sarah/AAV-9916-2021; Zhu, Yaowei/AAP-7961-2021; Farmakidis, Constantine/AAX-6847-2020; BRIL, vera/ABA-6509-2020; Ramchandren, Sindhu/D-6942-2012 ⓘ 7003634542; 56435469300; 23028497400; 57028883300; 55651716600; 57203867257; 7005070820; 57192424430; 35743615900; 44061744500; 55022752400; 57039184200; 6603926160; 55312159600; 16182474600; 58715400900; 59624428900; 55778025600; 12139692800; 7406071901; 35262926500; 58793477300 ⓘ sramcha4@its.jnj.com; ⓘ LANCET NEUROLOGY ⓘ LANCET NEUROL ⓘ 1474-4422 1474-4465 24 2 SCIE CLINICAL NEUROLOGY ⓘ 2024 45.5 0.2 15.37 2025-05-07 ⓘ 8 9 ⓘ CHOLESTEROL; MANAGEMENT; RECEPTOR ⓘ ⓘ Activities of Daily Living; Adult; Aged; Antibodies, Monoclonal, Humanized; Double-Blind Method; Female; Humans; Male; Middle Aged; Myasthenia Gravis; Receptors, Cholinergic; Treatment Outcome; albumin; azathioprine; cholesterol; cholinergic receptor antibody; cholinesterase inhibitor; enzyme antibody; high density lipoprotein; immunoglobulin; immunosuppressive agent; low density lipoprotein; low density lipoprotein receptor related protein 4 antibody; muscle specific tyrosine kinase antibody; nipocalimab; placebo; protein antibody; steroid; unclassified drug; cholinergic receptor; monoclonal antibody; adult; aged; albumin blood level; appendicitis; Article; Australia; Belgium; brain hemorrhage; Canada; China; controlled study; coronavirus disease 2019; Czech Republic; Denmark; double blind procedure; drug dose regimen; drug efficacy; drug fatality; drug safety; drug withdrawal; female; femur fracture; France; Germany; headache; health care quality; heart arrest; heart infarction; human; immunosuppressive treatment; immunotherapy; incidence; infection; infusion related reaction; infusion therapy; intention to treat analysis; Italy; Japan; lipoprotein blood level; liver disease; loading drug dose; maintenance drug dose; major clinical study; male; Mexico; monoclonal antibody therapy; multicenter study; muscle spasm; myasthenia gravis; myasthenia gravis activities of daily living; myasthenic crisis; open study; outcome assessment; outpatient department; peripheral edema; phase 3 clinical trial; plasmapheresis; Poland; randomized controlled trial; sepsis; side effect; South Korea; Spain; steroid therapy; sudden cardiac death; Sweden; Taiwan; thrombocytopenia; total cholesterol level; United States; unstable angina pectoris; urinary tract infection; urticaria; clinical trial; daily life activity; drug therapy; immunology; middle aged; myasthenia gravis; treatment outcome ⓘ English 2025 2025-02 10.1016/s1474-4422(24)00498-8 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Review ⓘ Single-Cell Nanoencapsulation: Chemical Synthesis of Artificial Cell-in-Shell Spores ⓘ Nature has evolved adaptive strategies to protect living cells and enhance their resilience against hostile environments, exemplified by bacterial and fungal spores. Inspired by cryptobiosis in nature, chemists have designed and synthesized artificial “cell-in-shell” structures, endowed with the protective and functional capabilities of nanoshells. The cell-in-shells hold the potential to overcome the inherent limitations of biologically naı̈ve cells, enabling the acquisition of exogenous phenotypic traits through the chemical process known as single-cell nanoencapsulation (SCNE). This review highlights recent advancements in the development of artificial spores, with sections organized based on the categorization of material types utilized in SCNE, specifically organic, hybrid, and inorganic types. Particular emphasis is placed on the cytoprotective and multifunctional roles of nanoshells, demonstrating potential applications of SCNEd cells across diverse fields, including synthetic biology, biochemistry, materials science, and biomedical engineering. Furthermore, the perspectives outlined in this review propose future research directions in SCNE, with the goal of achieving fine-tuned precision in chemical modulation at both intracellular and pericellular levels, paving the way for the design and construction of customized artificial spores tailored to meet specific functional needs. © 2025 American Chemical Society. ⓘ Rheem, Hyeong Bin; Kim, Nayoung; Nguyen, Duc Tai; Baskoro, Ghanyatma Adi; Roh, Jihun H.; Lee, Jungkyu K.; Kim, Beom Jin; Choi, Insung S. ⓘ Center for Cell-Encapsulation Research, Department of Chemistry, KAIST, Daejeon, 34141, South Korea; Center for Cell-Encapsulation Research, Department of Chemistry, KAIST, Daejeon, 34141, South Korea; Center for Cell-Encapsulation Research, Department of Chemistry, KAIST, Daejeon, 34141, South Korea; Department of Chemistry, University of Ulsan, Ulsan, 44776, South Korea; Department of Chemistry, University of Ulsan, Ulsan, 44776, South Korea; Department of Chemistry, Kyungpook National University, Daegu, 41566, South Korea; Department of Chemistry, University of Ulsan, Ulsan, 44776, South Korea, Basic-Clinic Convergence Research Institute, University of Ulsan, Ulsan, 44033, South Korea; Center for Cell-Encapsulation Research, Department of Chemistry, KAIST, Daejeon, 34141, South Korea, Department of Bio and Brain Engineering, KAIST, Daejeon, 34141, South Korea ⓘ ⓘ 57221305337; 57220797166; 57328977900; 58871735900; 58871975400; 8312040000; 59739925900; 7401471561 ⓘ kimbj@ulsan.ac.kr; ischoi@kaist.ac.kr; ⓘ Chemical Reviews ⓘ CHEM REV ⓘ 0009-2665 1520-6890 SCIE CHEMISTRY, MULTIDISCIPLINARY ⓘ 2024 55.8 0.2 N/A ⓘ 0 ⓘ ⓘ ⓘ Biomedical materials; Cell culture; Cells; Hybrid materials; Medical applications; Adaptive strategy; Artificial cell; Bacterial spore; Fungal spores; Hostile environments; In-shell; Living cell; Nano-encapsulation; Single cells; Synthesised; Metabolic engineering ⓘ English Article in press 2025 10.1021/acs.chemrev.4c00984 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Introduction of controllable 3D deformation to electrospun fibers using 3D printing ⓘ Recently, electrospun polymeric fibers and fibrous membranes have received considerable attention from various fields, including biomedical, electrical, environmental, and energy engineering, because of lots of advantages. However, electrospun fibers have significant limitations in terms of structural properties, being largely constrained to thin membranes (essentially two-dimensional structures). Achieving three-dimensional structural properties, especially regarding motion or deformation, remains a significant challenge. In this study, we present a novel fibrous membrane with controllable three-dimensional deformation capabilities. To induce a specific deformation, namely a convex surface, a polymeric framework was fabricated using melt extrusion-based printing on electrospun fibers. This framework provided both deformation guidance toward the desired shape and mechanical support for the electrospun fibers. The mechanical properties and deformation behavior of the membrane were experimentally evaluated using tensile tests, demonstrating successful production of the intended deformation in the fabricated membranes. Furthermore, the membranes exhibited excellent cell viability and facilitated topographical guidance for cell attachment and culture, as confirmed by cell culture tests using fibroblast and myoblast cell lines. ⓘ Kim, Jeong Hwa; Sin, Dong Wook; Jeong, Young Hun ⓘ Kyungpook Natl Univ, Sch Mech Engn, Daehakro 80, Bukgu 41566, Daegu, South Korea; ST1 Corp, Yongsugongdan 2 Gil 41, Busan 46006, South Korea ⓘ Jeong, Young/R-2486-2019 ⓘ 56485245200; 59921312600; 59922074000 ⓘ yhjeong@knu.ac.kr; ⓘ COMPOSITES PART B-ENGINEERING ⓘ COMPOS PART B-ENG ⓘ 1359-8368 1879-1069 304 SCIE ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, COMPOSITES ⓘ 2024 14.2 0.3 0 2025-06-11 ⓘ 0 0 Electrospinning; Nanofibers; Extrusion-based 3D printing; Fibrous membrane; Deformation mode ⓘ NANOFIBERS ⓘ Deformation mode; Electrospinning; Extrusion-based 3D printing; Fibrous membrane; Nanofibers ⓘ Cell engineering; Energy conservation; Environmental technology; Environmental testing; Fibrous membranes; 3-D deformation; 3-D printing; 3D-printing; Deformation modes; Electrospun fibers; Electrospuns; Energy engineering; Extrusion-based 3d printing; Polymeric fibers; Property; Tensile testing ⓘ English 2025 2025-09 10.1016/j.compositesb.2025.112638 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Recovery of chemicals and energy through thermo-chemical processing of plastic waste ⓘ To mitigate the various socioeconomic/environmental consequences associated with plastic waste, it is crucial to adopt strategic measures aimed at source reduction. In this regard, the thermo-chemical approach is a promising technical option to realize this objective within the framework of the circular economy. Such approach involves transforming plastic waste into chemicals/fuels, which contributes to the build-up of a more sustainable and resource-efficient platform. Precise control over yield and selectivity towards target chemicals (monomers, light olefins, and benzene, toluene, ethylbenzene, and xylene isomers (BTEXs)) and fuels (transportation fuels and syngas) is achievable by manipulating operating parameters for the thermo-chemical platform despite the possibly marked influence of the waste composition on product distribution. This review aims to delineate a technically viable pathway of the thermo-chemical approach with the discussion on the physico-chemical properties and compositional characteristics of plastics, technical alternatives for their recycling, and the associated environmental risks (improper disposal practices including mismanagement, landfilling, and incineration). This review helps open a new path for the development of a strategic technical approach within thermochemical processing to integrate different facets of plastic waste recycling. Thus, it will contribute to the realization of a closed-loop circular economy within the plastic value chain by focusing on thermo-chemical recycling of plastic waste. ⓘ Lee, Taewoo; Kwon, Dohee; Lee, Sangyoon; Kim, Youkwan; Kim, Jee Young; Song, Hocheol; Jung, Sungyup; Lee, Jechan; Tsang, Yiu Fai; Kim, Ki-Hyun; Kwon, Eilhann E. ⓘ Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Sungkyunkwan Univ, Dept Global Smart City, Suwon 16419, South Korea; Sungkyunkwan Univ, Sch Civil Architectural Engn & Landscape Architect, Suwon 16419, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Tai Po, Hong Kong 999077, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Tai Po, Hong Kong 999077, Peoples R China; Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea ⓘ Kwon, Eilhann/A-1225-2012; Song, Hocheol/ABD-7214-2021; Kim, Jee/AAO-8688-2020; Tsang, Yiu/AAJ-2524-2020; Lee, Jechan/J-1229-2016; LEE, TAEWOO/MXK-6996-2025; Jung, Sungyup/GZG-6207-2022 ⓘ 57194348573; 57208275497; 57214885455; 57204070895; 57191420766; 56562122800; 55073290800; 57188712886; 22954605700; 57196174153; 9240622100 ⓘ kkim61@hanyang.ac.kr; ek2148@hanyang.ac.kr; ⓘ PROGRESS IN ENERGY AND COMBUSTION SCIENCE ⓘ PROG ENERG COMBUST ⓘ 0360-1285 1873-216X 108 SCIE ENERGY & FUELS;ENGINEERING, CHEMICAL;ENGINEERING, MECHANICAL;THERMODYNAMICS ⓘ 2024 37 0.3 1.29 2025-05-07 ⓘ 3 3 Circular economy; Sustainability; Waste valorization; Thermo-chemical process; Plastic waste ⓘ HIGH-DENSITY POLYETHYLENE; FISCHER-TROPSCH SYNTHESIS; CATALYTIC PYROLYSIS; THERMAL-DEGRADATION; FLUIDIZED-BED; AIR GASIFICATION; SUPERCRITICAL WATER; RANGE HYDROCARBONS; CIRCULAR ECONOMY; MONOMER RECOVERY ⓘ Circular economy; Plastic waste; Sustainability; Thermo-chemical process; Waste valorization ⓘ Chemicals processing; Circular economy; Energy; Environmental consequences; Plastics waste; Socio-economics; Source reduction; Thermo chemical process; Thermo-chemical; Waste valorizations; Land fill ⓘ English 2025 2025-05 10.1016/j.pecs.2025.101219 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Toward a Privacy-Preserving Face Recognition System: A Survey of Leakages and Solutions ⓘ Recent advancements in face recognition (FR) technology in surveillance systems make it possible to monitor a person as they move around. FR gathers a lot of information depending on the quantity and data sources. The most severe privacy concern with FR technology is its use to identify people in real-time public monitoring applications or via an aggregation of datasets without their consent. Due to the importance of private data leakage in the FR environment, academia and business have given it a lot of attention, leading to the creation of several research initiatives meant to solve the corresponding challenges. As a result, this study aims to look at privacy-preserving face recognition (PPFR) methods. We propose a detailed and systematic study of the PPFR based on our suggested six-level framework. Along with all the levels, more emphasis is given to the processing of face images as it is more crucial for FR technology. We explore the privacy leakage issues and offer an up-to-date and thorough summary of current research trends in the FR system from six perspectives. We also encourage additional research initiatives in this promising area for further investigation. ⓘ Laishram, Lamyanba; Shaheryar, Muhammad; Lee, Jong taek; Jung, Soon ki ⓘ Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea ⓘ Jung, Soon Ki/P-7687-2018; Shaheryar, Muhammad/NBW-9729-2025 ⓘ 57219930647; 56132068000; 24341317500; 57226791905 ⓘ yanbalaishram@knu.ac.kr; shaheryar@knu.ac.kr; jongtaeklee@knu.ac.kr; skjung@knu.ac.kr; ⓘ ACM COMPUTING SURVEYS ⓘ ACM COMPUT SURV ⓘ 0360-0300 1557-7341 57 6 SCIE COMPUTER SCIENCE, THEORY & METHODS ⓘ 2024 28 0.3 8.86 2025-05-07 ⓘ 2 4 Privacy preservation; face recognition; surveillance system; face obfusca- tion; de-identification; face encryption; face privacy; deep learning ⓘ SECURE ⓘ de-identification; deep learning; face encryption; face obfuscation; face privacy; face recognition; Privacy preservation; surveillance system ⓘ Data obfuscation; Differential privacy; Face recognition; Privacy-preserving techniques; De-identification; Deep learning; Face encryption; Face obfuscation; Face privacy; Face recognition systems; Face recognition technologies; Privacy preservation; Privacy preserving; Surveillance systems; Information leakage ⓘ English 2025 2025-06 10.1145/3673224 ⓘ 바로가기 바로가기 바로가기 바로가기

Basic biomedical research conducted with PAI in preclinical studies has generated much interest and shown outstanding potential for clinical and commercial translation. PAI has captured morphological, functional and molecular information in studies of living animals and humans, providing intrinsic clinical indicators from early diagnosis through to treatment monitoring. This Review presents the fundamentals of PAI technology and various clinical PAI systems and addresses key findings from pilot and clinical patient studies of human organ systems. The Review also discusses technical and non-technical challenges in clinical scenarios, emphasizes the importance of standardization in accelerating clinical translation, and summarizes the current state of the PAI regulatory process. ⓘ Park, Jeongwoo; Choi, Seongwook; Knieling, Ferdinand; Clingman, Bryan; Bohndiek, Sarah; Wang, Lihong V.; Kim, Chulhong ⓘ Pohang Univ Sci & Technol POSTECH, Dept Elect Engn, Pohang, South Korea; POSTECH, Med Device Innovat Ctr, Daegu 41061, South Korea; Kyungpook Natl Univ, Sch Convergence, Dept Biomed Convergence Sci & Technol, Daegu 41566, South Korea; POSTECH, Inst Artificial Intelligence, Pohang, South Korea; Friedrich Alexander Univ FAU Erlangen Nurnberg, Univ Hosp Erlangen, Dept Pediat & Adolescent Med, D-91054 Erlangen, Germany; Seno Med Instruments Inc, San Antonio, TX USA; Univ Cambridge, Dept Biochem, Cambridge, England; Univ Cambridge, Canc Res UK Cambridge Inst, Cambridge, England; Calif Inst Technol CALTECH, Andrew & Peggy Cherng Dept Med Engn, Pasadena, CA USA; CALTECH, Dept Elect Engn, Pasadena, CA 91125 USA; POSTECH, Dept Convergence IT Engn, Pohang, South Korea; POSTECH, Dept Mech Engn, Pohang, South Korea; POSTECH, Dept Med Sci & Engn, Pohang, Gyeongbuk, South Korea; Opticho Inc, Pohang, South Korea ⓘ Bohndiek, Sarah/S-9416-2019; Choi, Seongwook/HZI-3187-2023; Kim, Chang-Hoon/D-7205-2016; Wang, Lihong/A-7147-2009; Knieling, Ferdinand/Z-6052-2019; Park, Jeongwoo/LIC-1971-2024 ⓘ 57205588351; 58627801200; 55471950700; 55173874200; 16311545900; 36071676700; 57202234822 ⓘ seb53@cam.ac.uk; LVW@caltech.edu; chulhong@postech.edu; ⓘ NATURE REVIEWS BIOENGINEERING ⓘ NAT REV BIOENG ⓘ 2731-6092 3 3 ESCI ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2024 37.6 0.4 17.5 2025-05-07 ⓘ 51 37 ⓘ MULTISPECTRAL OPTOACOUSTIC TOMOGRAPHY; MALIGNANT BREAST MASSES; HIGH-RESOLUTION; LYMPHATIC VESSELS; INDOCYANINE GREEN; LEARNING ANALYSIS; DISEASE SEVERITY; MOUSE-BRAIN; BLOOD-FLOW; ULTRASOUND ⓘ ⓘ ⓘ English 2025 2025-03 10.1038/s44222-024-00240-y ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Deep learning approaches for bruised mandarin orange classification by fluorescence hyperspectral imaging ⓘ Citrus fruit is extensively consumed worldwide, and the bruising of these fruit significantly affects their quality, impacting consumers' purchasing decisions. Detecting such damage during post-harvest operations is crucial. However, the bruised area does not exhibit distinct color differences compared with normal regions, complicating visual inspection and rendering it time-consuming. Consequently, this study investigates the potential of fluorescence hyperspectral imaging to discern bruised mandarin oranges. Hyperspectral images were acquired following illumination with a pair of 365 nm UV lights. Three multivariate data analyses-decision tree, support vector machine, and partial least squares discriminant analysis-and three deep learning models-ResNet50, EfficientNetB0, and MobileNet-were employed for the classification of bruised mandarins. Preprocessing steps, including dark and white correction, spectra preprocessing, and region of interest (ROI) extraction, were conducted prior to model development. Classification accuracy was determined through model training. Among the models, ResNet50 with nine principal component images exhibited high classification accuracy: 99.65 % for the training group, 100 % for the validation group, and 100 % for the test group. GradCAM visualization further confirmed the successful formation of heatmap over bruised areas. Thus, the classification of bruised mandarins using fluorescence hyperspectral imaging and deep learning is feasible, laying the groundwork for automated sorting technologies. ⓘ Lee, Ahyeong; Baek, Insuck; Kim, Jinse; Hong, Suk-Ju; Kim, Moon S. ⓘ Natl Inst Agr Sci, Dept Agr Engn, 310 Nongsaengmyeong Ro, Jeonju 54875, South Korea; ARS, USDA, Environm Microbial & Food Safety Lab, 10300 Baltimore Ave, Beltsville, MD 20705 USA; Kyungpook Natl Univ, Dept Smart Bioind Mech Engn, Daegu 41566, South Korea ⓘ ⓘ 57195997665; 55414110300; 56414601500; 57195994020; 57208234136 ⓘ hsj5596@knu.ac.kr; moon.kim@usda.gov; ⓘ POSTHARVEST BIOLOGY AND TECHNOLOGY ⓘ POSTHARVEST BIOL TEC ⓘ 0925-5214 1873-2356 230 SCIE AGRONOMY;FOOD SCIENCE & TECHNOLOGY;HORTICULTURE ⓘ 2024 6.8 0.4 ⓘ 0 0 Postharvest; Sorting; Remote sensing; Fruit; AI ⓘ MACHINE VISION; CITRUS-FRUITS; DEFECTS ⓘ AI; Fruit; Postharvest; Remote sensing; Sorting ⓘ ⓘ English 2025 2025-12 10.1016/j.postharvbio.2025.113724 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Dual-anion ionic liquid electrolytes: a strategy for achieving high stability and conductivity in lithium metal batteries ⓘ Ionic liquid electrolytes (ILEs) provide promising thermal and electrochemical stability characteristics for safer lithium metal batteries (LMBs). However, their development faces challenges due to their low ionic conductivity and poor wettability on separators. In this study, we introduce a dual-anion locally concentrated ionic-liquid electrolyte (D-LCILE), designed with a diluent and two distinct anions to significantly improve the ionic conductivity and wettability. These improvements were confirmed through electrochemical impedance spectroscopy (EIS) measurements on stainless steel symmetric cells, contact angle tests, and rate capability assessments on a 300 mu m thick lithium metal half-cell. Notably, the dual-anion design enhances the interfacial stability, as density functional theory (DFT) calculations revealed a more stable solvation shell structure, further supported by molecular dynamics (MD) simulations. Additionally, scanning electron microscopy (SEM) experiments confirmed the deposition of a thin and, dense lithium layer, while X-ray photoelectron spectroscopy (XPS) depth profile analysis showed a stable solid electrolyte interphase (SEI) with increased LiF content. Performance tests on a 20 mu m-thick Li & Vert;LiFePO4 full cell revealed an average Coulombic efficiency exceeding 99.90% and capacity retention >99.93% after 200 cycles at 1C, making D-LCILE a highly promising candidate for next-generation, high-performance LMBs. ⓘ Lee, Jemin; Choi, Wonwoo; Jang, Eunbin; Kim, Hyunjin; Yoo, Jeeyoung ⓘ Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Hyundai Motor Group37, Battery Mfg Engn Res & Dev Team, Prod Dev Div, Uiwang Si 16082, Gyeonggi Do, South Korea ⓘ Yoo, Jeeyoung/AAH-1359-2019 ⓘ 58959227800; 58589133700; 57837176500; 57214326580; 56046607500 ⓘ jyoo@knu.ac.kr; ⓘ ENERGY & ENVIRONMENTAL SCIENCE ⓘ ENERG ENVIRON SCI ⓘ 1754-5692 1754-5706 18 11 SCIE CHEMISTRY, MULTIDISCIPLINARY;ENERGY & FUELS;ENGINEERING, CHEMICAL;ENVIRONMENTAL SCIENCES ⓘ 2024 30.8 0.4 0 2025-05-07 ⓘ 0 0 ⓘ RECHARGEABLE BATTERIES; WETTABILITY; CHALLENGES; SEPARATOR; IMPEDANCE; LITFSI; SALTS; ANODE; SEI ⓘ ⓘ Depth profiling; Electrolytes; Lithium batteries; Lithium compounds; Negative ions; Positive ions; Capability assessment; Cell contacts; Electrochemical impedance spectroscopy measurements; Electrochemical stabilities; Ionic liquid electrolytes; Lithium metals; Rate capabilities; Symmetrics; Test capability; Thermal; battery; electrochemistry; electrolyte; lithium; scanning electron microscopy; wettability; X-ray spectroscopy; X ray photoelectron spectroscopy ⓘ English 2025 2025-06-03 10.1039/d5ee00119f ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ Construction of self-healing polycaprolactone composite foams with segregated structure for superior electromagnetic interference shielding ⓘ Electromagnetic interference shielding materials are inevitably damaged during service, causing a serious decline in their shielding performance. Therefore, it is urgent to develop polymer-based composites with excellent electromagnetic shielding and self-healing properties. In this study, a layered foam/film structure polycaprolactone composite characterized by electric/magnetic bifunctionality was constructed by a hot-pressing process and supercritical carbon dioxide foaming. The microcellular framework offers rich heterogeneous interfaces and improves electromagnetic attenuation capabilities. Such a reasonable construction of asymmetric shielding networks optimizes the impedance matching, while the incident electromagnetic waves form a special attenuation mode of "absorption-reflection-reabsorption". The polycaprolactone composite foam exhibits an excellent electromagnetic interference shielding effectiveness of 53.6 dB in the X-band and a low reflection value of only 0.36, effectively reducing secondary pollution. In addition, the damaged polycaprolactone composite foam exhibits over 93 % electromagnetic interference shielding effectiveness and healing efficiency, ensuring the long-term stability of the material in practical applications.

○ ○ Article ⓘ Pd nanoparticles fixed in zeolites promote low-temperature NO reduction via hydrogen spillover ⓘ H2-selective catalytic reduction is a promising NOx control technology owing to its high intrinsic activity at low temperatures. We investigated catalysts composed of Pd NPs fixed in ZSM-5, which demonstrated enhanced activity for NO reduction by H2 at T <= 150 degrees C, achieving over 95 % NOx conversion and N2 selectivity at 100 degrees C. This system was particularly suited for studying the influence of hydrogen spillover on NO reduction activity because the fixed Pd NPs cannot interact with NO, while ZSM-5 can mediate hydrogen spillover and activate NO away from the Pd NPs on the Br & Oslash;nsted acid sites. Quantifying the kinetic isotope effect, and using catalytic measurements and in-situ infrared spectroscopy, we elucidate the reaction mechanism governing the catalytic activity. Under reaction conditions (NO + O2 flow at 100 degrees C), it was found that NO is activated as nitrosyl complexes on in-situ formed Pd cations as well as charge-compensating NO+ species at the cation exchange sites of ZSM-5, with the latter species serving as active intermediates. At this stage, the activated NO+ species on Br & Oslash;nsted acid sites undergo selective reduction to N2 by reacting with spillover hydrogen from Pd NPs. Furthermore, the fixed Pd structure reduces the susceptibility to O2 chemisorption, enabling the Pd NPs to preserve their metallic state against oxidative poisoning for efficient H2 dissociation. Our study provides insights into the characterization of zeolite-fixed metal NPs, which is distinct from conventional analyses that focus on exposed metal sites. Moreover, this study highlights the fixation of metal NPs on zeolites as an effective strategy for NO reduction by H2. ⓘ Lee, Eunwon; Lee, Jaeha; Park, Dong Chan; Moon, Sei; Song, Inhak; Jung, Hyeongdong; Kim, Do Heui ⓘ Seoul Natl Univ, Inst Chem Proc, Sch Chem & Biol Engn, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Korea Univ, Coll Engn, Dept Integrat Energy Engn, Seoul 02841, South Korea ⓘ Kim, Heui/I-3727-2015; Park, Dong/AIE-8364-2022 ⓘ 57214728853; 59510667600; 57216340279; 58156677800; 56754610900; 58172021200; 8905508400 ⓘ dohkim@snu.ac.kr; ⓘ APPLIED CATALYSIS B-ENVIRONMENT AND ENERGY ⓘ APPL CATAL B-ENVIRON ⓘ 0926-3373 1873-3883 366 SCIE CHEMISTRY, PHYSICAL;ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 21.1 0.6 0 2025-05-07 ⓘ 0 0 Metal nanoparticle fixation; Zeolite; Acid site; Hydrogen spillover; NO reduction by H2 ⓘ SELECTIVE CATALYTIC-REDUCTION; NITRIC-OXIDE; IN-SITU; CONFINED CATALYSIS; METAL; ADSORPTION; PALLADIUM; H-2; CONVERSION; ADSORBERS ⓘ Acid site; Hydrogen spillover; Metal nanoparticle fixation; NO reduction by H<sub>2</sub>; Zeolite ⓘ Bioremediation; Bromine compounds; Infrared spectroscopy; Nitrogen oxides; Reaction kinetics; Zeolites; Acid site; Catalytic reduction; Hydrogen spill overs; Hydrogen spillover; Lows-temperatures; Metal nanoparticle fixation; NO reduction; NO reduction by H2; NO x; Pd nanoparticles; Selective catalytic reduction ⓘ English 2025 2025-06-05 10.1016/j.apcatb.2025.125060 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Sub-unit-cell-segmented ferroelectricity in brownmillerite oxides by phonon decoupling ⓘ The ultimate scaling limit in ferroelectric switching has been attracting broad attention in the fields of materials science and nanoelectronics. Despite immense efforts to scale down ferroelectric features, however, only few materials have been shown to exhibit ferroelectricity at the unit-cell level. Here we report a controllable unit-cell-scale domain in brownmillerite oxides consisting of alternating octahedral/tetrahedral layers. By combining atomic-scale imaging and in situ transmission electron microscopy, we directly probed sub-unit-cell-segmented ferroelectricity and investigated their switching characteristics. First-principles calculations confirm that the phonon modes related to oxygen octahedra are decoupled from those of the oxygen tetrahedra in brownmillerite oxides, and such localized oxygen tetrahedral phonons stabilize the sub-unit-cell-segmented ferroelectric domain. The unit-cell-wide ferroelectricity observed in our study could provide opportunities to design high-density memory devices using phonon decoupling. © The Author(s), under exclusive licence to Springer Nature Limited 2025. ⓘ Jang, Jinhyuk; Jin, Yeongrok; Nam, Yeon-Seo; Park, Heung-Sik; Kim, Jaegyu; Kang, Kyeong Tae; So, Yerin; Choi, Jiwoung; Choi, Youngchang; Shim, Jaechan; Sriboriboon, Panithan; Lee, Dong Kyu; Go, Kyoung-June; Kim, Gi-Yeop; Hong, Seungbum; Lee, Jun Hee; Lee, Daesu; Han, Myung-Geun; Son, Junwoo; Kim, Yunseok; Taniguchi, Hiroki; Kang, Seokhyeong; Lee, Jang-Sik; Tian, He; Yang, Chan-Ho; Zhu, Yimei; Cheong, Sang-Wook; Choi, Woo Seok; Lee, Jaekwang; Choi, Si-Young ⓘ Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea, Advanced Analysis Science & Engineering Team, Samsung Electronics, Hwaseong, South Korea; Department of Physics, Pusan National University, Busan, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea; Department of Physics, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea; Department of Physics, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea, Department of Materials Science and Engineering, KAIST, Daejeon, South Korea; Department of Physics, Sungkyunkwan University, Suwon, South Korea, Department of Physics, Kyungpook National University, Daegu, South Korea; Department of Physics, Kyungpook National University, Daegu, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea; Department of Electrical Engineering, POSTECH, Pohang, South Korea; School of Advanced Materials Science and Engineering, Sungkyunkwan University, Suwon, South Korea; School of Advanced Materials Science and Engineering, Sungkyunkwan University, Suwon, South Korea; Department of Materials Science and Engineering, Research Institute of Advanced Materials, Seoul National University, Seoul, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea; Department of Materials Science and Engineering, KAIST, Daejeon, South Korea; School of Energy and Chemical Engineering, Ulsan National Institute of Science and Technology, Ulsan, South Korea; Department of Physics, POSTECH, Pohang, South Korea; Condensed Matter Physics and Materials Science, Brookhaven National Laboratory, Upton, NY, United States; Department of Materials Science and Engineering, Research Institute of Advanced Materials, Seoul National University, Seoul, South Korea; School of Advanced Materials Science and Engineering, Sungkyunkwan University, Suwon, South Korea; Department of Physics, Nagoya University, Nagoya, Japan; Department of Electrical Engineering, POSTECH, Pohang, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea; School of Materials Science and Engineering, Zhejiang University, Hangzhou, China; Department of Physics, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea; Condensed Matter Physics and Materials Science, Brookhaven National Laboratory, Upton, NY, United States; Department of Physics and Astronomy, Rutgers University, Piscataway, NJ, United States; Department of Physics, Sungkyunkwan University, Suwon, South Korea; Department of Physics, Pusan National University, Busan, South Korea; Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea, Center for Van der Waals Quantum Solids, Institute for Basic Science, Pohang, South Korea, Department of Semiconductor Engineering, POSTECH, Pohang, South Korea ⓘ ⓘ 59904265700; 57219306590; 57376172200; 57204003957; 59006216200; 56002123900; 59904674200; 59183275300; 57221969238; 59903993800; 57201468374; 57210555713; 57218919757; 55941121600; 57328806400; 56493776300; 57221245705; 14044989500; 24170027100; 57200906063; 45761523600; 35848454700; 7601476249; 56799617300; 8509779400; 57219044799; 57205982477; 14031133800; 55888626200; 56493480000 ⓘ youngchoi@postech.ac.kr; jaekwangl@pusan.ac.kr; choiws@skku.edu; ⓘ Nature Materials ⓘ NAT MATER ⓘ 1476-1122 1476-4660 SCIE CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER ⓘ 2024 38.5 0.6 0 2025-06-11 ⓘ 0 ⓘ ⓘ ⓘ Brownmillerites; Cell levels; Decouplings; Ferroelectric features; Ferroelectric switching; Material science; Scale-down; Scaling limits; Sub-units; Unit cells ⓘ English Article in press 2025 10.1038/s41563-025-02233-7 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ An asymptotic approximation of the solution for nearly tridiagonal quasi-Toeplitz linear systems ⓘ We introduce an asymptotic approximate algorithm for solving nearly tridiagonal quasi-Toeplitz linear systems. When addressing low-rank perturbations of a tridiagonal Toeplitz matrix system based on the Sherman-Morrison-Woodbury formula (or Woodbury identity), conventional methods require solving at least two simpler systems. The proposed algorithm overcomes this limitation by providing an explicit asymptotic formula for one of these systems. This asymptotic approximation enables a rapid resolution of the original system with minimal additional computation. To validate the accuracy and efficiency of the proposed algorithm, we conduct numerical experiments on two cases, comparing the results with those of existing methods. The results demonstrate that the proposed algorithm significantly reduces computation time while maintaining accuracy compared to the existing methods. ⓘ Kim, Philsu; Park, Sangbeom; Kim, Seonghak; Bak, Soyoon ⓘ Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea ⓘ Bak, Soyoon/HSE-8486-2023 ⓘ 7402334786; 57374873000; 56489490600; 56450371300 ⓘ kimps@knu.ac.kr; piaoxf76@gmail.com; shkim17@knu.ac.kr; jiya525@knu.ac.kr; ⓘ MATHEMATICS AND COMPUTERS IN SIMULATION ⓘ MATH COMPUT SIMULAT ⓘ 0378-4754 1872-7166 234 SCIE COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;COMPUTER SCIENCE, SOFTWARE ENGINEERING;MATHEMATICS, APPLIED ⓘ 2024 4.4 0.7 0 2025-05-07 ⓘ 0 0 Tridiagonal Toeplitz matrix; Thomas algorithm; LU decomposition; Sherman-Morrison-Woodbury formula ⓘ SIMULATION; MATRICES; SCHEMES ⓘ LU decomposition; Sherman–Morrison–Woodbury formula; Thomas algorithm; Tridiagonal Toeplitz matrix ⓘ Approximation algorithms; Linear systems; Matrix algebra; Numerical methods; Approximate algorithms; Asymptotic approximation; Asymptotics; LU decomposition; Sherman-Morrison-Woodbury formulas; Thomas algorithm; Toeplitz linear systems; Toeplitz matrices; Tridiagonal; Tridiagonal toeplitz matrix; Consensus algorithm ⓘ English 2025 2025-08 10.1016/j.matcom.2025.02.024 ⓘ 바로가기 바로가기 바로가기 바로가기
