Article In vivo degradation of polyethylene terephthalate using microbial isolates from plastic polluted environment Accumulation of plastics alarms a risk to the environment worldwide. As polyethylene pterephthalate (PET) degrades slowly and produces hazardous substances, therefore, it is now essential to eliminate plastic wastes from the environment. Given that, the current study is concerned with PET degradation potential of naturally occurring microbial strains isolated from plastic waste dumping sites, Sarcina aurantiaca (TB3), Bacillus subtilis (TB8), Aspergillus flavus (STF1), Aspergillus niger (STF2). To test the biodegradability of PET films, the films were incubated for 60 days at 37 degrees C with the microorganisms designated as TB3, TB8, STF1, STF2 and the microbial consortium (TB3+TB8+STF1+STF2) in Minimal Salt Medium and Bushnell Hass Broth. Hydrophobicity, viability, and total protein content of isolates were investigated. Using Field Emission Scanning Electron Mi-croscopy and Fourier Transform Infrared Spectrophotometry to measure variations in functional groups and carbonyl index on PET surface, biodegradation process was affirmed by fissures and modified surfaces. Results revealed that the microbial consortium (S. aurantiaca + B. subtilis + A. flavus + A. niger) that the weight loss of PET films was 28.78%. The microbial consortium could be used to treat PET waste, posing no health or envi-ronmental risks. The developed microbial consortium has the potential to degrade PET, hence can be employed for eliminating PET in plastic contaminated sites.

Article In vivo tracking of toxic diesel particulate matter in mice using radiolabeling and nuclear imaging Exposure to diesel particulate matter (DPM) is associated with several adverse health effects, including severe respiratory diseases. Quantitative analysis of DPM in vivo can provide important information on the behavior of harmful chemicals, as well as their toxicological impacts in living subjects. This study presents whole-body images and tissue distributions of DPM in animal models, using molecular imaging and radiolabeling techniques. The self-assembly of the 89Zr-labeled pyrene analog with a suspension of DPM efficiently produced 89Zr-incorporated DPM (89Zr-DPM). Positron emission tomography images were obtained for mice exposed to89Zr-DPM via three administration routes: intratracheal, oral, and intravenous injection. DPM was largely distributed in the lungs and only slowly cleared after 7 days in mice exposed via the intratracheal route. In addition, a portion of 89Zr-DPM was translocated to other organs, such as the heart, spleen, and liver. Uptake values in these organs were also noticeable following exposure via the intravenous route. In contrast, most of the orally administered DPM was excreted quickly within a day. These results suggest that continuous inhalation exposure to DPM causes serious lung damage and may cause toxic effects in the extrapulmonary organs.

Article Increase of blood mercury level with shark meat consumption: A repeated-measures study before and after Chuseok, Korean holiday Sharks are known to contain high levels of mercury in their meat. However, few studies have directly assessed the changes in mercury concentration in the human body according to shark meat intake. One hundred and ninety-seven participants that traditionally consume shark meat during the Chuseok holiday were recruited from two areas of Gyeongsangbuk-do, South Korea to examine their blood mercury level before and after the holiday season. Blood mercury levels were measured before and after the holiday season. Characteristics such as the consumption of shark meat, intake amount, and the effect on mercury concentration were assessed during the survey. Univariable and multivariable analysis (Linear Mixed Model) were done for assessing the association between shark meat consumption of holiday season and blood mercury level. Among the total participants, 83 consumed shark meat during holiday. In the univariable analysis, a significant increase in blood mercury levels before and after Chuseok was observed only for the group that consumed shark meat during holiday. The multivariable analysis (adjusted for identified confounders that affect both exposure and outcome considering repeated measurements) showed that consuming shark meat was significantly associated with increased blood mercury levels by 3.56 μg/L (95% confidence interval [CI], 2.64–4.67 μg/L). In the model considering the amount consumed as two group, the level of increase was 2.61 μg/L (95% CI, 1.63–3.58 μg/L) for those consuming <100 g, and 6.20 μg/L (95% CI, 4.77–7.62 μg/L) for those consuming ≥100 g compared to group without consuming shark meat. Considering amount consumed as continuous value, 0.02 μg/L (95% CI, 0.01–0.02 μg/L) of blood mercury increase was significantly associated with consuming 1 g. Consumption of shark meat significantly elevated blood mercury levels, exceeding commonly suggested reference concentrations in less than 2 weeks. These findings suggest the need for public health warnings and regulations regarding shark meat consumption. © 2023 Elsevier Ltd Baek, Kiook; Park, Chulyong; Sakong, Joon Department of Occupational and Environmental Medicine, Yeungnam University Hospital, Daegu, South Korea, Department of Medicine, Graduate School of Kyungpook National University, Daegu, South Korea; Department of Occupational and Environmental Medicine, Yeungnam University Hospital, Daegu, South Korea, Department of Preventive Medicine and Public Health, College of Medicine, Yeungnam University, Daegu, South Korea; Department of Occupational and Environmental Medicine, Yeungnam University Hospital, Daegu, South Korea, Department of Preventive Medicine and Public Health, College of Medicine, Yeungnam University, Daegu, South Korea 57190335322; 57190335503; 6506105070 jjsakong@gmail.com; Chemosphere CHEMOSPHERE 0045-6535 1879-1298 344 SCIE ENVIRONMENTAL SCIENCES 2023 8.1 8.8 0.24 2025-06-25 2 Dietary exposure; Food contamination; Heavy metals; Mixed model; Seafood; Traditional food Animals; Food Contamination; Holidays; Humans; Meat; Mercury; Republic of Korea; Seafood; Sharks; South Korea; Blood; Chemical contamination; Mercury (metal); heavy metal; mercury; mercury; Confidence interval; Dietary exposure; Food contamination; Meat consumption; Mercury concentrations; Mercury levels; Mixed modeling; Seafood; Shark meat; Traditional food; blood; heavy metal; pollution exposure; public health; seafood; adult; Article; blood sampling; confounding variable; controlled study; dietary exposure; directed acyclic graph; female; food contamination; human; human experiment; human tissue; limit of quantitation; major clinical study; male; meat consumption; medical examination; outcome assessment; outcome variable; South Korea; animal; food contamination; leisure; meat; sea food; shark; Meats English Final 2023 10.1016/j.chemosphere.2023.140317 바로가기 바로가기 바로가기
Article Microplastic contamination in commercial fish species in southern coastal region of India Due to its potential impact on food safety and human health, commercial species that have been contaminated with microplastics (MPs) are drawing more attention on a global scale. This study investigated the possibility of MPs contamination in different marine fish species with substantial commercial value that was captured off the south coast of India, from Adyar and Ennore regions. Over the course of six months, from October 2019 to March 2020, 220 fish were examined. It was discovered that the gills and guts had accumulated more numbers of MPs (1115 MPs) of which 68% were fibres and fragments. The commercial fish samples contained an average of 3.2-7.6 MPs per fish. Greater MPs pollution is seen in the Ennore regions. The prevalence of MPs was observed in carnivorous and planktivorous fish collected from both the sites. Fish guts contained the most MPs, according to the data. Pelagic fish accounted for the least amount of MPs, followed by mid-and demersal fish. Four different types of polymers were also identified in the present study: polyethylene, polypropylene, polystyrene, and polyamide. These results clearly showed the degree of microplastic contamination in fish tissues from the south Indian coastal regions of Adyar and Ennore. These results we hope will create a baseline data for MPs contamination in commercial fish species. The presence of MPs in the fish could have detrimental effects both on the environment and human health and thus comprehensive steps are required to prevent plastic pollution of the environment in south India's coastal region.

Article Morphology and phylogenetic relationships of two Antarctic strains within the genera Carolibrandtia and Chlorella (Chlorellaceae, Trebouxiophyceae) The genera Carolibrandtia and Chlorella have been described as small green algae with spherical cell shapes that inhabit various environments. Species of these genera are often difficult to identify because of their simple morphology and high phenotypic plasticity. We investigated two small coccoid strains from Antarctica based on morphology, molecular phylogeny by two alignment methods which have been applied to previous phylogenetic studies of the genus Chlorella, and comparison of the secondary structures of nuclear small subunit (SSU) and internal transcribed spacer (ITS) rDNA sequences. Light microscopy of two strains revealed spherical cells containing chloroplasts with pyrenoids, and the morphological characteristics of the strains were nearly identical to those of other Chlorella species. However, based on the phylogenetic analyses of nuclear SSU and ITS rDNA sequences, it was determined that the Antarctic microalgal strains belonged to two genera, as the Chlorella and Carolibrandtia. In addition, the secondary structures of the SSU and ITS2 sequences were analyzed to detect compensatory base changes (CBCs) that were used to identify and describe the two strains. A unique CBC in the SSU rDNA gene was decisive for distinguishing strain CCAP 211/45. The ITS2 rDNA sequences for each strain were compared to those obtained previously from other closely related species. Following the comparison of morphological and molecular characteristics, we propose KSF0092 as a new species, Chlorella terrestris sp. nov., and the reassignment of the strain Chlorella antarctica CCAP 211/45 into Carolibrandtia antarctica comb. nov.

Article Understanding the biodegradation pathways of azo dyes by immobilized white-rot fungus, Trametes hirsuta D7, using UPLC-PDA-FTICR MS supported by in silico simulations and toxicity assessment No biodegradation methods are absolute in the treatment of all textile dyes, which leads to structure-dependent degradation. In this study, biodegradation of three azo dyes, reactive black 5 (RB5), acid blue 113 (AB113), and acid orange 7 (AO7), was investigated using an immobilized fungus, Trametes hirsuta D7. The degraded me-tabolites were identified using UPLC-PDA-FTICR MS and the biodegradation pathway followed was proposed. RB5 (92%) and AB113 (97%) were effectively degraded, whereas only 30% of AO7 was degraded. Molecular docking simulations were performed to determine the reason behind the poor degradation of AO7. Weak binding affinity, deficiency in H-bonding interactions, and the absence of interactions between the azo (-N--N-) group and active residues of the model laccase enzyme were responsible for the low degradation efficiency of AO7. Furthermore, cytotoxicity and genotoxicity assays confirmed that the fungus-treated dye produced non-toxic metabolites. The observations of this study will be useful for understanding and further improving enzymatic dye biodegradation.

Article An Improved Model for Evaluating the Hydraulic Behaviour of a Single Rock Joint Considering Contact Area Evolution During Shearing The contact of rock joints during shearing induced by underground excavation significantly impacts the hydro-mechanical behaviour of fractured rock mass, since fluid tends to flow through a rough-walled fracture along connected channels while bypassing the contact areas with tortuosity. However, previous research mostly considered joint roughness or aperture changes based on 2D joint profiles, while the contact and tortuosity using 3D surfaces were often overlooked. This paper considers the evolution of contact area and aperture distribution during shearing. The concept of the critical inclination angle is introduced and correlated with the contact area during shearing based on Grasselli's criterion. The standard deviation of the mean mechanical aperture is calculated using the modified algorithm. An improved model for estimating the hydraulic aperture with the mechanical aperture is then developed, applying an aperture correction term and a contact correction term. A number of shear-flow tests on artificial joint samples under constant normal loads are conducted. The accuracy and reliability of the proposed model are verified by comparing it against the experimental results and by comparing the prediction performance with other published models. Results show that the proposed model can improve the prediction of the hydraulic aperture and hydraulic conductivity of a single rock joint during shearing. Highlights An improved model is proposed to estimate hydraulic aperture with mechanical aperture, incorporating aperture and contact correction terms. The evolutions of geometric morphologies during shear can be computed, and the effects on flow behaviour are well described. A series of coupled shear-flow tests are conducted on two artificial joints with different surface characteristics under constant normal loads. The proposed model can predict the shear-flow coupled behaviour of rock joints with good accuracy. Zhu, X.; Gao, M.; Si, G.; Zhang, C.; Moon, J-S; Oh, J.

Article Controllable growth of porous morphology in low dielectric polyimides via thermal-driven spontaneous phase separation Fabricating porous polymer films with precise morphological control via a conventional phase separation method is challenging. Herein, porous polyimide (PPI) film formation kinetics was thoroughly investigated to understand the underlying phenomena during the thermally induced phase separation. The porous films were prepared using a poly(amic acid) (PAA) solution with a small-molecular phase dispersion agent (i.e., porogen), dibutyl phthalate (DBP), which is miscible with the PAA chains. Using amine-functionalized polyhedral oligo-meric silsesquioxane (NH2-POSS) as an additional nucleating agent, sponge-like NH2-POSS end-capped PPI (PPI/ NH2-POSSx) films were fabricated with tunable pore size (16.3-76.9 mu m) and porosity (42.6-69.4 %). This ensured control over the porous structure of the PPI/NH2-POSSx film, providing desirable low dielectric prop-erties (a minimum of 2 at 1 MHz) in broad frequency and temperature range as well as high thermal stability (Tg = 363-385 degrees C, T5% = 519-559 degrees C), and good mechanical strength (17-23 MPa). It was found that the porous structure and physical properties of the PPI/NH2-POSSx films can be readily engineered by tailoring the initial content of a removable porogen and cage silsesquioxane. This work will provide a new perspective on fabricating temperature-resistant low-dielectric porous polymer films with tunable pore sizes via thermal-driven sponta-neous phase separation with efficient processability.

Article Joint Precoding and Artificial Noise Design for MU-MIMO Wiretap Channels Secure precoding superimposed with artificial noise (AN) is a promising transmission technique to improve security by harnessing the superposition nature of the wireless medium. However, finding a jointly optimal precoding and AN structure is very challenging in downlink multi-user multiple-input multiple-output wiretap channels with multiple eavesdroppers. The major challenge in maximizing the secrecy rate arises from the non-convexity and non-smoothness of the rate function. Traditionally, an alternating optimization framework that identifies beamforming vectors and AN covariance matrix has been adopted; yet this alternating approach has limitations in maximizing the secrecy rate. In this paper, we put forth a novel secure precoding algorithm that jointly and simultaneously optimizes the beams and AN covariance matrix for maximizing the secrecy rate when a transmitter has either perfect or partial channel knowledge of eavesdroppers. To this end, we first establish an approximate secrecy rate in a smooth function. Then, we derive the first-order optimality condition in the form of the nonlinear eigenvalue problem (NEP). We present a computationally efficient algorithm to identify the principal eigenvector of the NEP as a suboptimal solution for secure precoding. Simulations demonstrate that the proposed methods improve secrecy rate significantly compared to the existing methods.

Article Redundancy Management in Federated Learning for Fast Communication One of the most critical challenges of federated learning (FL) is to send data efficiently and reliably over the noisy wireless channels between the clients and server to achieve target learning accuracy as fast as possible. To achieve this goal, we design effective error correction coded FL with managed retransmissions. Rather than using Shannon capacity as the performance measure to design the communication mechanisms for FL, our approach relies critically on learning accuracy. Our fundamental idea is based on the observation that Stochastic Gradient Decent (SGD) and its family can tolerate some errors in the course of training. Inspired by this, to reduce the communication burden without degrading the learning accuracy, our FL framework with Managed Redundancy (FL-MR) has two phases: (i) the No-Retransmission phase, where retransmissions are never performed even in case of erroneous decoding of data and (ii) the Select Retransmission phase, where only some carefully selected data packets are retransmitted. Our extensive simulation results demonstrate that the proposed coded FL system achieves target accuracies much faster than the baseline coded approach.

Article Temperature-directed fluorescent switchable nanoparticles based on P3OT-PNIPAM nanogel composite Poly(N-isopropylacrylamide) (PNIPAM) is a unique stimuli-responsive material that exhibits a lower critical solution temperature (LCST). Owing to this characteristic temperature-dependent behavior, PNIPAM has found extensive utilization as an active material in various applications, including sensors, drug delivery, and cellular imaging. Herein, we demonstrate temperature-directed fluorescent switchable nanoparticles based on poly(3octylthiophene-2,5-diyl) (P3OT) nanoaggregate-embedded PNIPAM nanogel composites (POPNs) featuring different crosslinker contents. The amount of P3OT loading in the nanogel composites can be gradually controlled by varying the crosslinking density of the PNIPAM matrix; this may be attributable to the efficient entrapment of P3OT nanoaggregates in case of a dense polymeric network with the increase in crosslinking density. POPNs exhibit dramatic temperature-dependent fluorescence enhancement (by a factor of 2.11). This is based on the environmental changes affecting fluorescent P3OT chains at temperatures below and above the LCST of the PNIPAM matrix. Based on this temperature-directed fluorescent switching capability, POPN could find potential applications in various fields, including biomedical imaging and sensors.

Article Hierarchical and game-theoretic decision-making for connected and automated vehicles in overtaking scenarios This paper presents a hierarchical and game-theoretic decision-making strategy for connected and automated vehicles (CAVs). A CAV can receive preview information using vehicle-to -everything (V2X) communication systems, and the optimal short-and long-term trajectory can be planned using this information. Specifically, in this study, the aggressiveness of all preceding vehicles in the car-following scenario can be estimated globally by monitoring the history of their time-series behaviors, before the CAV initiates a particular action, which is performed at the upper layer of the proposed decision-making structure. If it is determined that initiating a specific action is advantageous, the action is initiated, and the CAV then interacts with the vehicles locally to achieve its driving goal in a game-theoretical manner at the lower layer. In multiple test scenarios, we demonstrate the usefulness of our approach compared to the conventional decision-making approaches, and it shows a significant improvement in terms of success rates.

Article Probing the relationship between chemical structure and thermal degradation behavior of acetone fractionated kraft lignin This study reports the relationships between structure and thermal degradation behavior of industrial softwood and hardwood kraft lignin (KL) after acetone fractionation to obtain acetone soluble (AS) and acetone insoluble (AI) fractions with reduced structural polydispersity. The structure and thermal degradation behavior of AS-KL and AI-KL was examined by gel permeation chromatography, Fourier transform infrared, quantitative carbon-13 nuclear magnetic resonance spectroscopy, and thermogravimetric analysis. The results showed that the AS-KL fractions had reduced apparent molecular weight, lower polydispersity, less native wood lignin side chains, greater aromatic hydroxyl groups, and more condensed structures. In contrast, the AI-KL fractions showed substantially larger apparent molecular weight and polydispersity, as well as more aliphatic hydroxyl groups and native lignin side chains. Consequently, AI-KL samples exhibited greater thermal degradation activation energy than those of AS-KL samples because the former fractions had a larger apparent molecular weight as well as more aliphatic OH groups, which facilitated hydrogen bonding between lignin polymers, improving their thermal stability. This finding suggests that acetone fractionation of KL can be used to examine the relationship between structure and thermal degradation of industrial KL. These results also provide important information on the thermal degradation behavior of acetone fractionated products with relevant chemical and physical properties for a specific application, such as raw materials for lignin valorization.

Article Skin Test-Guided Strategy to Select Alternative Iodinated Contrast Media in Patients With Immediate Hypersensitivity Reaction: A Prospective Confirmative Study BACKGROUND: Iodinated contrast media (ICM) are a common cause of drug-induced immediate hypersensitivity reaction (IHR). Repeated use of ICM is often necessary; therefore, a standardized protocol to prevent recurrence of IHR is required.OBJECTIVE: We aimed to propose an intradermal skin test (IDT)-guided strategy for previous reactors to prevent recurrence of IHR.METHODS: We conducted a prospective multicenter study from May 2018 to December 2020 and recruited patients who had experienced IHR to ICM. Once enrolled, the participants underwent IDT with a causative ICM. The alternatives for reexposure were selected using the following protocol: (1) if the IDT with the culprit ICM was positive, further skin tests with other available ICM were conducted to choose IDT-negative agents as alternatives, and (2) if the IDT with the culprit ICM was negative, a randomly changed ICM was used without additional skin tests. The recurrence and severity of hypersensitivity were assessed in subsequent computed tomography examinations. Premedication was administered according to the severity of the index event in all cases.RESULTS: A total of 496 participants were enrolled, and 299 were reexposed to ICM. Among 269 participants who followed the protocol, 228 (84.8%) completed computed tomography examinations without adverse reactions, and IHR recurred in 16 of 30 participants (53.3%) who did not follow the protocol (P < .001). In addition, application of the protocol reduced the severity of IHR in recurred cases (P [ 0.003).CONCLUSIONS: Our IDT-guided strategy not only reduced recurrence of IHR to ICM but also mitigated the severity in recurred cases. This provides evidence for recommending an IDT to diagnose ICM allergy and find safe alternatives.(c) 2023 American Academy of Allergy, Asthma & Immunology (J Allergy Clin Immunol Pract 2023;11:3454-62) Lee, Ji-Hyang; Yoo, Youngsang; Kim, Sung-Ryeol; Lee, Jae-Hyun; Kim, Seo-Young; An, Jin; Park, So-Young; Park, Han-ki; Kim, Sujeong; Song, Woo-Jung; Yang, Min-suk; Kwon, Hyouk-Soo; Park, Hye-Kyung; Lee, Jaechun; Hur, Gyu-Young; Ko, Gang-Jee; Kim, Sang-Heon; Kim, Sae-Hoon; Ye, Young-min; Koh, Young-Il; Lee, Byung-Jae; Cho, You Sook; Yong, Hwan Seok; Kim, Tae-Bum Univ Ulsan, Coll Med, Asian Med Ctr, Dept Allergy & Clin Immunol, Seoul, South Korea; Gangneung Asan Hosp, Dept Internal Med, Div Pulm & Allergy & Crit Care Med, Kangnung, South Korea; Yonsei Univ, Coll Med, Dept Internal Med, Div Allergy & Immunol, Seoul, South Korea; Univ Kyung Hee, Kyung Hee Univ Hosp Gangdong, Dept Pulm Allergy & Crit Care Med, Coll Med, Seoul, South Korea; Chung Ang Univ, Dept Internal Med, Div Pulmonol Allergy & Crit Care Med, Coll Med, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Allergy & Clin Immunol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Allergy & Clin Immunol, Daegu, South Korea; Seoul Natl Univ, Boramae Med Ctr, Seoul Metropolitan Govt, Dept Internal Med, Seoul, South Korea; Pusan Natl Univ, Coll Med, Dept Internal Med, Busan, South Korea; Jeju Natl Univ, Coll Med, Dept Internal Med, Jeju, South Korea; Korea Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Hanyang Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seongnam, South Korea; Ajou Univ, Sch Med, Dept Allergy & Clin Immunol, Suwon, South Korea; Chonnam Natl Univ, Chonnam Natl Univ Hosp, Dept Allergy & Clin Immunol, Med Sch, Gwangju, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med, Dept Internal Med,Div Allergy, Seoul, South Korea; Korea Univ, Dept Radiol, Guro Hosp, Seoul, South Korea; Univ Ulsan, Asan Med Ctr, Dept Internal Med, Div Allergy & Clin Immunol,Coll Med, 88 Olymp ro 43 gil, Seoul 05505, South Korea Park, Hye-Kyung/Q-5586-2019; Kim, Jin-Seok/AAK-5424-2020; Kim, Sujeong/NJS-2378-2025; Lee, JongGu/B-7384-2013; Lee, Jae-Hyun/H-2260-2016; Park, Han-Ki/AAY-3102-2020; Kim, Sung-Ryeol/L-9266-2019 57208203071; 57345593400; 56396079900; 55911774100; 58537476300; 57207952209; 59466241200; 57218664064; 36666447400; 37062104600; 7404927140; 35285863400; 57208252986; 23991023300; 7004193730; 8310760600; 58154851000; 35198322400; 13405438300; 58914386100; 27171988300; 7404469543; 8697835600; 57206927697 tbkim@amc.seoul.kr; JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE J ALLER CL IMM-PRACT 2213-2198 2213-2201 11 11 SCIE ALLERGY;IMMUNOLOGY 2023 8.2 9.0 1.04 2025-06-25 8 7 Immediate hypersensitivity reaction; Intradermal skin test; Iodinated contrast media; Prevention DIAGNOSIS Immediate hypersensitivity reaction; Intradermal skin test; Iodinated contrast media; Prevention Contrast Media; Drug Hypersensitivity; Drug-Related Side Effects and Adverse Reactions; Humans; Hypersensitivity; Hypersensitivity, Immediate; Iodine Compounds; Prospective Studies; Skin Tests; iobitridol; iodinated contrast medium; iodixanol; iohexol; iomeprol; iopamidol; iopromide; ioversol; contrast medium; iodine derivative; adult; allergy; Article; clinician; computer assisted tomography; controlled study; cross reaction; disease severity; female; human; immediate type hypersensitivity; intracutaneous test; major clinical study; male; middle aged; multicenter study; null result; prospective study; recurrence risk; skin test; statistically significant result; adverse drug reaction; clinical trial; complication; drug hypersensitivity; hypersensitivity; immediate type hypersensitivity; skin test English 2023 2023-11 10.1016/j.jaip.2023.07.004 바로가기 바로가기 바로가기 바로가기
Article Adaptive mating selection based on weighted indicator for Multi/Many-objective evolutionary algorithm Decomposition-based Multi/Many-Objective Evolutionary Algorithms (DMOEAs) employ uniformly spaced reference vectors which may be appropriate for Multi-objective Optimization Problems (MOPs) with continuous Pareto Fronts (PFs). However, when solving MOPs which are characterized by discontinuous and/or degenerated PFs, it is essential to identify the regions where no solutions are bound to exist and identify the corresponding reference vectors referred to as ineffective reference vectors. In literature, various frameworks were proposed to classify the reference vectors into effective and ineffective during the process of evolution based on their association with the solutions in the population. However, due to the stochastic nature of the evolutionary process, some of the effective weight vectors may fail to associate with the solutions in the population and are misclassified as ineffective. Therefore, the region corresponding to the particular reference vector should be thoroughly explored before labeling it as ineffective. In this paper, the reference vectors are divided into three classes, namely, effective, possible ineffective and true ineffective vectors. Then, the regions corresponding to the possible ineffective reference vectors are thoroughly explored before finally classifying them as effective or ineffective. In order to facilitate the exploration corresponding to the different regions, an adaptive mating selection based on weighted ISDE+(IwSDE+) is proposed. In addition, the adaptive mating selection also facilitates the exploration of sparser regions once all the reference vectors are classified as effective or ineffective. The performance of the MOEA with the proposed Adaptive Mating Selection, referred to as AMS-MOEA significantly outperforms or is comparable to MOEADAWA, NSGA-III, ANSGA-III, MOEA/DD, RVEA, TDEA, 1by1EA, ISDE+ and iRVEA in 65%, 93.75%, 88.75%, 76.25%, 87.5%, 77.5%, 93.75%, 76.25% and 86.25% of cases, respectively. & COPY; 2023 Elsevier B.V.
