| ○ | ○ | Article | First report on Enterocytozoon hepatopenaei (EHP) infection in Pacific white shrimp (Penaeus vannamei) cultured in Korea | The microsporidian Enterocytozoon hepatopenaei (EHP) is an intracellular parasite that is a critical threat to the global shrimp farming industry. This parasite replicates in the hepatopancreas and midgut, and infected shrimp exhibit reduced feeding and growth retardation. In this study, we describe the first known EHP infection in the Pacific white shrimp (Penaeus vannamei) cultured in Korea. Histopathological examination showed basophilic inclusions in the hepatopancreatic tubule epithelial cells of the infected shrimp. PCR targeting small subunit (SSU) rRNA sequences showed that the resultant EHP sequences from the shrimp culture pond was >99.0% identical to EHPs found in Southeast Asian countries, but were distant from the Latin American isolate. We also compared the nucleotide sequences of the EHP spore wall protein (SWP) gene from the cultured shrimp and pond water to those from other EHPs from different geographical locations. Phylogenetic analyses using the sequenced SSU rRNA and SWP genes confirmed the close resemblance of the newly isolated Korean EHP to those from Southeast Asian countries, suggesting that it might have been introduced from those countries. The emergence of EHP in Korea will have a significant impact on shrimp production; therefore, the presence and prevalence of EHP in shrimp culture in addition to its pond water should be monitored carefully to control its spread in the Korean shrimp culture industry. | Kim, Ji Hyung; Lee, Chorong; Jeon, Hye Jin; Kim, Bum Keun; Lee, Nam-kyung; Choi, Seong-Kyoon; Han, Jee Eun | Korea Res Inst Bioscience & Biotechnol, Infect Dis Res Ctr, Daejeon 34141, South Korea; Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Korea Res Inst Bioscience & Biotechnol, Biotherapeut Translat Res Ctr, Daejeon 34141, South Korea; DGIST, Core Prot Resources Ctr, Daegu 42988, South Korea; DGIST, Div Biotechnol, Daegu 42988, South Korea; Kyungpook Natl Univ, Coll Vet Med, 80 Daehak Ro, Daegu 41566, South Korea | Kim, Ji Hyung/B-7321-2011 | 57225000204; 56707749200; 57212193058; 57225056167; 57191954466; 55505432500; 57214671240 | cskbest@dgist.ac.kr;jehan@knu.ac.kr; | AQUACULTURE | AQUACULTURE | 0044-8486 | 1873-5622 | 547 | SCIE | FISHERIES;MARINE & FRESHWATER BIOLOGY | 2022 | 4.5 | 6.0 | 3.36 | 2025-06-25 | 24 | 25 | Microsporidian; Parasite; Southeast Asian countries; Small subunit rRNA; Spore wall protein gene | NECROSIS DISEASE AHPND; LITOPENAEUS-VANNAMEI; SYNDROME VIRUS; MONODON | Microsporidian; Parasite; Small subunit rRNA; Southeast Asian countries; Spore wall protein gene | Korea; Decapoda (Crustacea); Enterocytozoon; Litopenaeus vannamei; cell; histopathology; host-parasite interaction; infectivity; new record; protein; shrimp culture | English | 2022 | 2022-01-30 | 10.1016/j.aquaculture.2021.737525 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | A comparative transcriptomics and eQTL approach identifies SlWD40 as a tomato fruit ripening regulator | A reliable approach based on comparative transcriptomics and eQTL is valuable for ripening regulator identification. Although multiple vital genes with strong effects on the tomato (Solanum lycopersicum) ripening process have been identified via the positional cloning of ripening mutants and cloning of ripening-related transcription factors (TFs), recent studies suggest that it is unlikely that we have fully characterized the gene regulatory networks underpinning this process. Here, combining comparative transcriptomics and expression QTLs, we identified 16 candidate genes involved in tomato fruit ripening and validated them through virus-induced gene silencing analysis. To further confirm the accuracy of the approach, one potential ripening regulator, SlWD40 (WD-40 repeats), was chosen for in-depth analysis. Co-expression network analysis indicated that master regulators such as RIN (ripening inhibitor) and NOR (nonripening) as well as vital TFs including FUL1 (FRUITFUL1), SlNAC4 (NAM, ATAF1,2, and CUC2 4), and AP2a (Activating enhancer binding Protein 2 alpha) strongly co-expressed with SlWD40. Furthermore, SlWD40 overexpression and RNAi lines exhibited substantially accelerated and delayed ripening phenotypes compared with the wild type, respectively. Moreover, transcriptome analysis of these transgenics revealed that expression patterns of ethylene biosynthesis genes, phytoene synthase, pectate lyase, and branched chain amino transferase 2, in SlWD40-RNAi lines were similar to those of rin and nor fruits, which further demonstrated that SlWD40 may act as an important ripening regulator in conjunction with RIN and NOR. These results are discussed in the context of current models of ripening and in terms of the use of comparative genomics and transcriptomics as an effective route for isolating causal genes underlying differences in genotypes. | Zhu, Feng; Jadhav, Sagar Sudam; Tohge, Takayuki; Salem, Mohamed A.; Li, Je Min; Giovannoni, James J.; Cheng, Yunjiang; Alseekh, Saleh; Fernie, Alisdair R. | Max Planck Inst Molekulare Pflanzenphysiol, Muhlenberg 1, D-14476 Potsdam, Germany; Huazhong Agr Univ, Natl R&D Ctr Citrus Preservat, Key Lab Hort Plant Biol, Minist Educ, Wuhan 430070, Peoples R China; Menoufia Univ, Fac Pharm, Dept Pharmacognosy & Nat Prod, Menoufia 32511, Egypt; Cornell Univ, Boyce Thompson Inst Plant Res, Ithaca, NY 14853 USA; USDA ARS, Robert Holley Ctr Agr & Hlth, Ithaca, NY 14853 USA; Hubei Hongshan Lab, Wuhan 430070, Peoples R China; Ctr Plant Syst Biol & Biotechnol, Plovdiv 4000, Bulgaria; Kyungpook Natl Univ, Hort Sci, Daegu, South Korea | fernie, alisdair/IWD-9278-2023; Lee, Je Min/F-9797-2014; Lee, Je/AAE-7496-2020; Jadhav, Sagar/JAN-6252-2023; Alseekh, Saleh/LSM-3566-2024; Salem, Mohamed/D-9675-2018; Giovannoni, James J./LTE-4376-2024; Tohge, Takayuki/G-7924-2017; Salem, Mohamed A./D-9675-2018 | alseekh@mpimp-golm.mpg.de;fernie@mpimp-golm.mpg.de; | PLANT PHYSIOLOGY | PLANT PHYSIOL | 0032-0889 | 1532-2548 | 190 | 1 | SCIE | PLANT SCIENCES | 2022 | 7.4 | 6.1 | 16 | QUANTITATIVE TRAIT LOCI; MADS-BOX GENE; INTROGRESSION LINE; CAROTENOID ACCUMULATION; METABOLIC SHIFTS; SYSTEMS BIOLOGY; EXPRESSION; REVEALS; INHIBITOR; PENNELLII | English | 2022 | 2022-08-29 | 10.1093/plphys/kiac200 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | A myosin XI adaptor, TAPE, is essential for pollen tube elongation in rice | In rice, TAPE is an essential myosin XI adaptor in pollen tube elongation. Pollen tube (PT) elongation is important for double fertilization in angiosperms and affects the seed-setting rate and, therefore, crop productivity. Compared to Arabidopsis (Arabidopsis thaliana L.), information on PT elongation in rice (Oryza sativa L.) is limited by the difficulty in obtaining homozygous mutants. In a screen of T-DNA insertional mutants, we identified a mutant in the Tethering protein of actomyosin transport in pollen tube elongation (TAPE) gene with an unusual segregation ratio by genotyping analysis. A CRISPR/Cas9 knockout mutant of TAPE that produced a short PT was sterile, and TAPE was expressed specifically in pollen grains. TAPE is a homolog of a myosin XI adaptor in Arabidopsis with three tetratricopeptide repeat and Phox and Bem1 protein domains. TAPE showed latrunculin B-sensitive, actin-dependent localization to the endoplasmic reticulum. Yeast two-hybrid screening and transcriptome analysis revealed that TAPE interacted with pollen-specific LIM protein 2b and elongation factor 1-alpha. Loss of TAPE affected transcription of 1,259 genes, especially genes related to cell organization, which were downregulated. In summary, TAPE encodes a myosin XI adaptor essential for rice PT elongation. | Hong, Woo-Jong; Kim, Eui-Jung; Yoon, Jinmi; Silva, Jeniffer; Moon, Sunok; Min, Cheol Woo; Cho, Lae-Hyeon; Kim, Sun Tae; Park, Soon Ki; Kim, Yu-Jin; Jung, Ki-Hong | Kyung Hee Univ, Grad Sch Green Bio Sci, Yongin 17104, South Korea; Kyung Hee Univ, Crop Biotech Inst, Yongin 17104, South Korea; Pusan Natl Univ, Dept Plant Biosci, Miryang 50463, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Pusan Natl Univ, Dept Life Sci & Environm Biochem, Miryang 50463, South Korea | ; Hong, Woo-Jong/HPF-0756-2023; Jung, Ki/L-5570-2019 | 57194418669; 57214231436; 55460491000; 56780864200; 7401616474; 57189515849; 35110429900; 57225142626; 8055974900; 57074286200; 56022522000 | yjkim2020@pusan.ac.kr;khjung2010@khu.ac.kr; | PLANT PHYSIOLOGY | PLANT PHYSIOL | 0032-0889 | 1532-2548 | 190 | 1 | SCIE | PLANT SCIENCES | 2022 | 7.4 | 6.1 | 0.88 | 2025-06-25 | 8 | 9 | ENDOPLASMIC-RETICULUM MOTILITY; CELL-GROWTH; PROTEINS; TRANSPORT; ACTIN; IDENTIFICATION; CYTOSKELETON; INTEGRITY; MEMBRANE; PATHWAY | English | 2022 | 2022-08-29 | 10.1093/plphys/kiac299 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Restored Action Generative Adversarial Imitation Learning from observation for robot manipulator | In this paper, a new imitation learning algorithm is proposed based on the Restored Action Generative Adversarial Imitation Learning (RAGAIL) from observation. An action policy is trained to move a robot manipulator similar to a demonstrator's behavior by using the restored action from stateonly demonstration. To imitate the demonstrator, the trajectory is generated by Recurrent Generative Adversarial Networks (RGAN), and the action is restored from the output of the tracking controller constructed by the state and the generated target trajectory. The proposed imitation learning algorithm is not required to access the demonstrator's action (internal control signal such as force/torque command) and provides better learning performances. The effectiveness of the proposed method is validated through the experimental results of the robot manipulator.(c) 2022 ISA. Published by Elsevier Ltd.

| ○ | ○ | Article | An energy stable finite difference method for anisotropic surface diffusion on closed curves | In this paper, we develop an energy stable finite difference method for the problem of curve motion under anisotropic surface diffusion. The motion of curve by anisotropic surface diffusion is governed by the fourth-order (highly nonlinear) geometric evolution equation. As in Li and Bao (2021), we first split the fourthorder evolution equation into two second-order equations, where the position vector of curve and the weighted curvature are treated as unknowns. Instead of using the arclength parameter, we introduce a Lagrangian coordinate parameter such that a closed curve can be parametrized over a fixed interval so that the equations can be represented using the new parameter. We then propose a linearly semiimplicit finite difference method to discretize these two equations, and prove that the scheme satisfies discrete energy dissipation so it is energy stable under suitable condition on the anisotropic surface energy. To show the applicability of our present method, we perform several numerical tests on various initial curves and different anisotropic energies. The numerical results show that our scheme is indeed energy dissipative and conserves even the total area well. (c) 2021 Elsevier Ltd.

| ○ | ○ | Article | An ultralong-life SnS-based anode through phosphate-induced structural regulation for high-performance sodium ion batteries | As a star representative of transition metal sulfides, SnS is viewed as a promising anode-material candidate for sodium ion batteries due to its high theoretical capacity and unique layered structure. However, the extremely poor electrical conductivity and severe volume expansion strongly hinder its practical application while achieving a high reversible capacity with long-cyclic stability still remains a grand challenge. Herein, different from the conventional enhancement method of elemental doping, we report a rational strategy to introduce PO43 into the SnS layers using phytic acid as the special phosphorus source. Intriguingly, the presence of PO43 in the form of Sn-O-P covalent bonds can act as a conductive pillar to buffer the volume expansion of SnS while expanding its interlay spacing to allow more Na+ storage, supported by both experimental and theoretical evidences. Profiting from this effect combined with microstructural metrics by loading on high pyridine N-doped reduced graphene oxide, the as-prepared material presented an unprecedented ultra-long cyclic stability even after 10,000 cycles along with high reversible capacity and excellent full-cell performances. The findings herein open up new opportunities for elevating electrochemical performances of metal sulfides and provide inspirations for the fabrication of advanced electrode materials for broad energy use.

| ○ | ○ | Article | Economic Impact of Donating a Kidney on Living Donors: A Korean Cohort Study | Rationale & Objective: Although existing studies have reported adverse health outcomes after kidney donation, its socioeconomic impact on living donors requires further study. Study Design: A retrospective observational cohort study including a matched comparison group. Setting & Participants: 1,285 living kidney donors from 7 tertiary hospitals between 2003 and 2016, and a matched comparison group consisting of the same number of health screening examinees with similar baseline clinical characteristics and socio-economic status. All participants were receiving Korean national health insurance. Exposure: Kidney donation as reflected in the Korean National Health Insurance System (NHIS) database. Outcome: Changes in household economic status estimated by Korean national health insurance fees and changes in employment status reflected in the NHIS database. Analytical Approach: The outcomes of the donor group and matched control group were compared annually using multivariable logistic regression analyses adjusted for clinical and demographic characteristics. Results: The median ages of the donors and matched controls were 45 and 46 years, respectively; 44.6% of both groups were male. Compared to the comparison group, living donors were at higher risk of being unemployed or losing employment during the first 2 years after donation (eg, first-year loss of employment: odds ratio (OR), 2.27 [95% CI, 1.55-3.33]); however, this association did not persist. Donors also had a significantly lower odds of improvement in economic status (OR, 0.57 [95% CI, 0.47-0.71]) and a higher odds of deterioration in financial status (OR, 1.54 [95% CI, 1.23-1.93]) in the first year after transplantation and subsequently. Limitations: Unmeasured differences between donors and matched controls creating residual selection bias and confounding. Conclusions: Living kidney donors may suffer loss of employment and poor economic status after their voluntary donation. The socioeconomic impact on these donors should be considered in conjunction with the potential long-term adverse health outcomes after donation. | Park, Sehoon; Park, Jina; Kang, Eunjeong; Lee, Jang Wook; Kim, Yaerim; Park, Minsu; Kim, Kwangsoo; Kim, Hyo Jeong; Han, Miyeun; Cho, Jang-Hee; Lee, Jung Pyo; Lee, Sik; Kim, Soo Wan; Park, Sang Min; Chae, Dong-Wan; Chin, Ho Jun; Kim, Yong Chul; Kim, Yon Su; Choi, Insun; Lee, Hajeong | Seoul Natl Univ, Dept Biomed Sci, Seoul, South Korea; Seoul Natl Univ, Dept Internal Med, 101 Daehak Ro, Seoul 03080, South Korea; Seoul Natl Univ, Dept Internal Med, Coll Med, Seoul Natl Univ Hosp, Seoul, South Korea; Seoul Natl Univ, Dept Internal Med, Boramae Med Ctr, Seoul, South Korea; Seoul Natl Univ, Transdisciplinary Dept Med & Adv Technol, Seoul, South Korea; Korea Univ, Dept Biostat, Coll Med, Seoul, South Korea; Ewha Womans Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Keimyung Univ, Dept Internal Med, Sch Med, Daegu, South Korea; Chungnam Natl Univ, Dept Informat & Stat, Daejeon, South Korea; Natl Evidence Based Hlthcare Collaborating Agcy, Div Hlthcare Technol Assessment Res, Seoul, South Korea; Pusan Natl Univ Hosp, Dept Internal Med, Pusan, South Korea; Kyungpook Natl Univ, Dept Internal Med, Daegu, South Korea; Chonbuk Natl Univ Hosp, Dept Internal Med, Jeonju, South Korea; Chonnam Natl Univ Hosp, Dept Internal Med, Gwangju, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seongnam, South Korea | Lee, Hyo/G-6299-2019; Kim, Won-Young/AHE-5670-2022; Cho, Jang-hee/ABD-3534-2020; Kim, Sang/J-5399-2012; Lee, Jun-Young/N-5963-2019; Chin, Ho/J-5678-2012; Kim, Dae/AAJ-7518-2021; Kim, Nan/T-8627-2019; Han, Miyeun/AAE-7569-2022; Kim, Yong/L-8653-2019; Chae, Dong-Wan/J-5681-2012; Lee, Ji Ye/ABA-7830-2021 | 57210030734; 57221837324; 56577278700; 57223232128; 57202790600; 57201652582; 57210575084; 57476930200; 55899659500; 7403536291; 56028990400; 57192521521; 56108124300; 58509146900; 23471686900; 23495522400; 57026583000; 7410205767; 57311279600; 36554389800 | mdhjlee@gmail.com; | AMERICAN JOURNAL OF KIDNEY DISEASES | AM J KIDNEY DIS | 0272-6386 | 1523-6838 | 79 | 2 | SCIE | UROLOGY & NEPHROLOGY | 2022 | 13.2 | 6.2 | 1.09 | 2025-06-25 | 8 | 8 | TRANSPLANTATION; MORTALITY; DIALYSIS; RISKS | Economic hardship; economic status; employment; end-stage renal disease (ESRD); epidemiology; health care policy; health insurance; income; kidney donation; kidney transplantation; living donor; socioeconomic deprivation | Cohort Studies; Humans; Kidney; Kidney Transplantation; Living Donors; Male; Middle Aged; Nephrectomy; Republic of Korea; Retrospective Studies; adult; Article; cohort analysis; controlled study; data base; demography; economic aspect; employment; female; health care system; health insurance; high risk population; human; kidney donor; kidney transplantation; Korean (people); living donor; major clinical study; male; mass screening; middle aged; observational study; retrospective study; social status; tertiary care center; unemployment; epidemiology; kidney; kidney transplantation; nephrectomy; South Korea | English | 2022 | 2022-02 | 10.1053/j.ajkd.2021.07.009 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of number of air holes on flame and heat transfer characteristics in a multihole baffled combustor combined with micro-thermophotovoltaic and micro-thermoelectric systems | Currently, micro power generators have been widely drawing attention for various applications. In this study, the H-2-air micro combustor (MC) with a multihole baffle plate was combined with two power generators based on micro-thermophotovoltaic and micro-thermoelectric systems. The reacting flow and conjugate heat transfer including the MC wall were analyzed by the detailed reaction mechanism and the outer wall condition of convection and radiation. From the resulting thermal fields, the characteristics of heat emission and electrical potential were examined. Eight baffles with different numbers of air holes (Na) and three global equivalence ratios were selected, and a baffle with N-a = infinity was adopted to compare the multihole and annular air flows. The combustion characteristics depending on Na were explored by analyzing the changes in the reaction zone, the flammable range, reaction rate, and wall heat transfer rate. The N-a effect on wall and center recirculation zones was comparable to the variation due to other geometrical variables of the baffle plate. As N-a increased, the combustion efficiency increased to 20% of the N-a = infinity case. The combustion efficiency equivalent to the swirl MC was obtained for Na = 5-8, having enhanced preheating effects and large center recirculation zones. Compared to N-a = infinity the mean temperature of the multihole baffled MC increased by 6.4%-19.2% depending on Na. The emitter efficiency related a TPV system was comparable to the swirling flow MC. For a thermoelectric generator, the conversion efficiency of N-a = infinity was similar to that of a Swiss-roll MC, and the multihole baffled MC showed a high conversion efficiency of 1.55%-3.58% depending on N-a and the global equivalence ratio. | Kim, Won Hyun; Park, Tae Seon | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57481555200; 7401801892 | tsparkjp@knu.ac.kr; | APPLIED THERMAL ENGINEERING | APPL THERM ENG | 1359-4311 | 1873-5606 | 208 | SCIE | ENERGY & FUELS;ENGINEERING, MECHANICAL;MECHANICS;THERMODYNAMICS | 2022 | 6.4 | 6.2 | 1.06 | 2025-06-25 | 14 | 13 | Micro combustor; Multihole baffle; Three-dimensional recirculation; Preheating effect; Combustion efficiency; Energy conversion efficiency | THERMAL PERFORMANCE; GENERATOR; MODEL | Combustion efficiency; Energy conversion efficiency; Micro combustor; Multihole baffle; Preheating effect; Three-dimensional recirculation | Combustion; Combustors; Electronic equipment; Preheating; Thermoelectric energy conversion; Thermoelectric equipment; Thermoelectricity; Air holes; Combustion efficiencies; Energy conversion efficiency; Micro combustor; Micro-thermophotovoltaic; Multi holes; Multihole baffle; Preheating effect; Recirculations; Three-dimensional recirculation; Conversion efficiency | English | 2022 | 2022-05-25 | 10.1016/j.applthermaleng.2022.118180 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Efficacy and Safety of Udenafil Once Daily in Patients with Erectile Dysfunction after Bilateral Nerve-Sparing Robot-Assisted Laparoscopic Radical Prostatectomy: A Randomized, Double-Blind, Placebo-Controlled Study | Purpose: To evaluate the efficacy and safety of udenafil 75 mg once daily in patients with erectile dysfunction following bilateral nerve-sparing robot-assisted laparoscopic radical prostatectomy (BNS-RALP). Materials and Methods: A multi-center, prospective, randomized, controlled, double-blind study was conducted. Among patients with localized prostate cancer with international index of erectile function-erectile function domain (IIEF-EF) score of 18 or higher before BNS-RALP, those who developed postoperative erectile dysfunction (IIEF-EF score 14 or less at 4 weeks after BNS-RALP) were enrolled. Enrolled patients were randomly assigned to the udenafil 75 mg daily group or the placebo group in a 2:1 ratio. Each subject was followed up at 8 weeks (V2), 20 weeks (V3), and 32 weeks (V4) to evaluate the efficacy and safety of udenafil. Results: In all, 101 patients were screened, of whom 99 were enrolled. Of the 99 patients, 67 were assigned to the experimental group and 32 to the control group. Ten (14.93%) patients in the experimental group and 10 (31.25%) in the control group dropped out of the study. After 32 weeks of treatment, IIEF-EF score of 22 or higher was seen in 36.51% (23/63) of patients in the experimental group and 13.04% (3/23) patients in the control group (p=0.021). The proportion of patients with IIEF-EF improvement of 25% or more compared to the baseline was 82.54% (52/63) in the experimental group and 62.96% (17/27) in the control group (p=0.058). Conclusions: Udenafil 75 mg once daily after BNS-RALP improved the erectile function without any severe adverse effects.

| ○ | ○ | Article | Enhancement of cooling performance in traction motor of electric vehicle using direct slot cooling method | The torque of a traction motor for electric vehicles is directly proportional to the electric current applied to the motor winding. Since a power increment is directly linked with an increase in torque, traction motors with high electric current are needed to enhance the dynamic performance of electric vehicles. However, heat loss in the winding, which is proportional to the square of the applied electric current, may cause insulation breakdown in the winding or demagnetisation of permanent magnets in the rotor. In this study, we employed direct slot cooling (DSC) to directly cool motor windings, which are the main heat source in a motor, with cooling fluids. To evaluate the performance of DSC, we compared it with existing motor-cooling technologies, such as water-jacket, end-tip and channel cooling. The performances of the cooling methods were compared based on the change in the pumping power of the cooling fluid and the winding current density. Under two real road driving modes (urban dynamometer and highway driving modes), we compared the change in temperature with time in the traction motor of a compact car with the various cooling methods. The proposed DSC model showed good cooling performance; the winding maximum temperature did not exceed 90 degrees C in the highway driving mode, even when a high current density of 70 A/mm2 was momentarily applied. | Park, Joonbum; An, Jaehyuck; Han, Kyoungseok; Choi, Hong -Soon; Park, Il Seouk | Kyungpook Natl Univ, Dept Mech Engn, 80 Daehakr, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Mech Engn, 80 Daehakro, Daegu 41566, South Korea | 57900435600; 57900036800; 56465294700; 7404338767; 50262800000 | einstein@knu.ac.kr; | APPLIED THERMAL ENGINEERING | APPL THERM ENG | 1359-4311 | 1873-5606 | 217 | SCIE | ENERGY & FUELS;ENGINEERING, MECHANICAL;MECHANICS;THERMODYNAMICS | 2022 | 6.4 | 6.2 | 2.92 | 2025-06-25 | 34 | 37 | Traction motor; Motor cooling; Direct slot cooling; Current density; Pumping power | DESIGN | Current density; Direct slot cooling; Motor cooling; Pumping power; Traction motor | Current density; Dynamometers; Electric losses; Electric traction; Electric vehicles; Electric windings; Traction motors; Vehicle performance; Winding; Cooling fluids; Cooling methods; Cooling performance; Direct slot cooling; Driving mode; Motor cooling; Motor windings; Performance; Power; Pumping power; Cooling | English | 2022 | 2022-11-25 | 10.1016/j.applthermaleng.2022.119082 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | External Torque Estimation Using Higher Order Sliding-Mode Observer for Robot Manipulators | Online monitoring of external torque/force is receiving much attention with the increasing demand in industries, where robot manipulators are required to cooperate with humans, assemble product parts or perform certain tasks that involve the interaction with fragile objects. Estimation of external torque when the robot manipulator interacts with the external environment is investigated in this article. A higher order sliding-mode-based observer is designed to estimate the external torque online against nonlinear friction. Moreover, a Luenberger observer is designed to stabilize the general momenta error dynamics by using sum of squares programming. Lyapunov analysis is considered to demonstrate the stability of an overall system and the convergence of angular position tracking errors. Simulation as well as experimental results using 7-DOF Sawyer robot under various practical scenarios demonstrate the effectiveness of the proposed scheme. | Kommuri, Suneel Kumar; Han, Seungyong; Lee, Sangmoon | Xian Jiaotong Liverpool Univ, Dept Elect & Elect Engn, Suzhou 215123, Peoples R China; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | Lee, Sangmoon/C-4502-2018; Han, Seungyong/AAN-8632-2021 | 56021916300; 57200991395; 59510733500 | Suneel.Kommuri@xjtlu.edu.cn;seungyong@knu.ac.kr;moony@knu.ac.kr; | IEEE-ASME TRANSACTIONS ON MECHATRONICS | IEEE-ASME T MECH | 1083-4435 | 1941-014X | 27 | 1 | SCIE | AUTOMATION & CONTROL SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;ENGINEERING, MANUFACTURING;ENGINEERING, MECHANICAL | 2022 | 6.4 | 6.2 | 3.25 | 2025-06-25 | 39 | 44 | Observers; Torque; Manipulators; Force; Manipulator dynamics; Friction; Convergence; External torque estimation; model uncertainties; robotic manipulator; robust-observer design | STRICT LYAPUNOV FUNCTIONS; CHATTERING REDUCTION; MOTION CONTROL; FORCE | External torque estimation; model uncertainties; robotic manipulator; robust-observer design | Flexible manipulators; Human robot interaction; Industrial robots; Modular robots; Robot applications; Torque; Angular positions; External environments; Higher order sliding modes; Luenberger observers; Lyapunov analysis; Nonlinear friction; Online monitoring; Robot manipulator; Industrial manipulators | English | 2022 | 2022-02 | 10.1109/tmech.2021.3067443 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | ICA-Evolution Based Data Augmentation with Ensemble Deep Neural Networks Using Time and Frequency Kernels for Emotion Recognition from EEG-Data | The aim of this study is to recognize human emotions from electroencephalographic (EEG) signals using deep neural networks. Large training data is an important prerequisite for successful implementation of deep neural networks. In this view, we propose an independent component analysis (ICA) - evolution based data augmentation method. This method performs ICA to extract and accumulate clean independent components (ICs) of each class. The new ICs are generated by selection which uses a fitness function such as mutual information (MI) and crossover in component space. Data augmentation is done by performing mutation, and crossover on generated data in sensor space. Since EEG signals are non-stationary, with time-varying frequency contents, emotional patterns associated with EEG are detected in the time-frequency (TF) domain using a spectrogram. To extract emotion related features from a spectrogram, we train an ensemble convolutional neural networks (CNNs) with convolutional kernels in time and frequency axes. The information integrated over both the axes is concatenated and fed to long short-term memory (LSTM). We used the benchmark DEAP dataset for emotion classification to evaluate our approach. The results highlight the potential of proposed ICA-evolution based data augmentation and an ensemble CNNs with LSTM model for emotion recognition. | Kang, Jun-Su; Kavuri, Swathi; Lee, Minho | Kyungpook Natl Univ, Sch Elect Engn, Deagu 41566, South Korea | Lee, Min-Ho/ABE-5735-2021; Kang, Jun-Su/AAH-2131-2020 | 55696431800; 34881754200; 57191730119 | wkjuns@gmail.com;swathi.kavuri@gmail.com;mholee@gmail.com; | IEEE TRANSACTIONS ON AFFECTIVE COMPUTING | IEEE T AFFECT COMPUT | 1949-3045 | 13 | 2 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, CYBERNETICS | 2022 | 11.2 | 6.2 | 1.64 | 2025-06-25 | 26 | 32 | Emotion recognition; EEG; data augmentation; ICA; evolutionary algorithm; CNNs | ELECTROENCEPHALOGRAM; CLASSIFICATION; CONVERGENCE; SELECTION | CNNs; data augmentation; EEG; Emotion recognition; evolutionary algorithm; ICA; LSTM | Biomedical signal processing; Brain; Classification (of information); Convolution; Deep neural networks; Electroencephalography; Independent component analysis; Long short-term memory; Spectrographs; Convolutional neural network; Data augmentation; Electroencephalographic signals; Emotion recognition; Human emotion; Independent components; Independent components analysis; Spectrograms; Time and frequencies; Training data; Speech recognition | English | 2022 | 2022 (APR-JUN) | 10.1109/taffc.2019.2942587 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optimization of oil flow distribution inside the in-wheel motor assembly of electric vehicles for improved thermal performance | The efficiency of an electric vehicle in-wheel motor depends largely on its thermal performance, which is contingent upon effective and active cooling. However, an experimental investigation of the in-wheel motor is challenging due to several factors, such as high-speed operational conditions and direct contact limitations. The present study aims to optimize the cooling oil flow distribution within the in-wheel motor assembly by varying the geometric parameters of the flow channel. A central composite design methodology was employed to develop the design of numerical analysis. A response surface analysis was conducted based on the computational results to formulate an empirical correlation. Finally, a multi-objective genetic algorithm was used to attain optimal design parameters of the in-wheel motor cooling channel. Moreover, the in-wheel motor assembly based on the optimal cooling channel design was numerically simulated to elucidate the influence of design parameters on the thermal performance of the motor at different operating conditions. The optimal design configuration leads to an overall improved heat dissipation at the maximum motor speed of 11000 rpm and reduced temperatures of critical in-wheel motor components such as bearings and resolvers by 8% and 6.4% respectively. Furthermore, average heat transfer enhancements of 0.1% and 8.1% over the direct spray cooling area and secondary spray cooling areas compared to the simple spray cooling configuration were observed at the maximum speed. | Saleem, Arslan; Park, Myeong Hyeon; Ambreen, Tehmina; Kim, Sung Chul | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Korea Univ, Sch Mech Engn, Seoul 02841, South Korea; Yeungnam Univ, Sch Mech Engn, 280 Daehak Ro, Gyongsan 38541, South Korea | Saleem, Arslan/ABA-5982-2021; park, myeong/J-1314-2019 | 57194776354; 57328577700; 57195420431; 57213778436 | sungkim@ynu.ac.kr; | APPLIED THERMAL ENGINEERING | APPL THERM ENG | 1359-4311 | 1873-5606 | 201 | SCIE | ENERGY & FUELS;ENGINEERING, MECHANICAL;MECHANICS;THERMODYNAMICS | 2022 | 6.4 | 6.2 | 2.39 | 2025-06-25 | 32 | 35 | Electric vehicle; In-wheel motor; Motor cooling; Thermal management; Oil spray cooling | Electric vehicle; In-wheel motor; Motor cooling; Oil spray cooling; Thermal management | Channel flow; Electric vehicles; Genetic algorithms; Optimal systems; Surface analysis; Traction motors; Vehicle performance; Vehicle wheels; Active cooling; Cooling channels; Flow distribution; In-wheel motor; Motor cooling; Oil flow; Oil spray cooling; Optimisations; Spray-cooling; Thermal Performance; Cooling | English | 2022 | 2022-01-25 | 10.1016/j.applthermaleng.2021.117753 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Refrigerant circuitry optimization of finned tube heat exchangers using a dual-mode intelligent search algorithm | This paper presents a novel dual-mode search algorithm for refrigerant circuitry optimization, which is implemented in two modules, namely, the knowledge-based computational module (KBCM) and the permutationbased computational module (PBCM). The KBCM determines the appropriate number of tubes for each heat exchanger circuit based on the related non-uniform airflow velocity distribution, whereas the PBCM establishes the optimal or near-optimal sequence in which tubes are linked. The method is designed to maximize the heat exchanger capacity while minimizing the computational costs by excluding infeasible circuits. By combining the KBCM and PBCM techniques, significant gains of 9.64%, 9.87%, 6.96%, and 7.16% in the heat exchanger capacity are observed for the part-load cooling conditions according to the European standard EN14825, particularly for outdoor unit heat exchangers with a non-uniform airflow distribution. | Ishaque, Shehryar; Kim, Man-Hoe | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IEDT, Daegu 41566, South Korea | 57212480549; 55686310000 | shehryar.ishaque@knu.ac.kr;manhoe.kim@knu.ac.kr; | APPLIED THERMAL ENGINEERING | APPL THERM ENG | 1359-4311 | 1873-5606 | 212 | SCIE | ENERGY & FUELS;ENGINEERING, MECHANICAL;MECHANICS;THERMODYNAMICS | 2022 | 6.4 | 6.2 | 0.68 | 2025-06-25 | 12 | 10 | Finned tube heat exchanger; Optimization; Refrigerant circuitry; Part-load cooling conditions; Dual-mode search algorithm | PERFORMANCE; CONDENSER; DESIGN | Dual-mode search algorithm; Finned tube heat exchanger; Optimization; Part-load cooling conditions; Refrigerant circuitry | Air; Fins (heat exchange); Knowledge based systems; Learning algorithms; Refrigerants; Tubes (components); Cooling conditions; Dual modes; Dual-mode search algorithm; Finned tube heat exchangers; Knowledge based; Optimisations; Part load; Part-load cooling condition; Refrigerant circuitry; Search Algorithms; Timing circuits | English | 2022 | 2022-07-25 | 10.1016/j.applthermaleng.2022.118576 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Mechanistic Determination of Doping Contrast from Fermi Level Pinned Surfaces in the Scanning Electron Microscope Using Energy-Filtered Imaging and Calculated Potential Distributions | Secondary electron (SE) doping contrast in the scanning electron microscope is correlated with Fermi level pinned surfaces of Si samples prepared using HF-based wet-chemical treatment or focused ion beam (FIB) micromachining en route to quantitative dopant profiling. Using energy-resolved SE imaging techniques and finite-element analyses of surface states and surface junction potentials, we clarified the surface band-bending effects post-NH4F-treatment, consistent with brighter p-contrast from degenerately doped (>10(19) cm(-3)) regions. In general, SE spectromicroscopy scan measurements unambiguously indicated heavy suppression of patch fields, while the empirical discovery of scan frequency-modulated contrast inversion due to Chee et al. [Springer Proceedings in Physics, 120, pp. 407-410 (2008)] is ascribable to competing fixed oxide charge and dynamic charge injection phenomena ( particularly at dwell times >29 mu s). Leveraging numerical simulations of electric potentials and variable-voltage experimental data, the theoretical model based on amorphization damage-mediated Fermi level pinning is elucidated for Ga+ FIB-processed site-specific doping contrast on patch field-free surfaces. This work successfully argues against the notion that doping contrast ultimately or exclusively entails patch fields or adventitious metal-semiconductor contacts. | Chee, Augustus K.
