| 1 | 海洋层积云中的云滴谱宽度及其影响因子显示文摘云滴谱宽度对模式中云的光学厚度的参数化、气溶胶间接效应的评估以及降水形成过程的研究至关重要。本文利用美国POST(Physics of Stratocumulus Top)项目2008年7月19日的飞机观测资料,分析了微物理量和云滴谱的垂直分布及微物理过程。结果表明,该云系云滴谱宽度在云底附近较大,这是由低层核化过程导致的;中层凝结增长过程使得云滴谱宽度随高度增加逐渐减小;云顶附近夹卷混合过程导致云滴谱宽度增大。绝热云中垂直速度的增大会促进云凝结核的活化使云滴数浓度增大,促进凝结增长使云滴尺度增大、云滴谱宽度减小,云滴谱宽度与云滴数浓度、云滴尺度呈现负相关关系;云洞中受夹卷混合过程影响,垂直速度减小,云滴蒸发,云滴数浓度和云滴尺度减小、云滴谱宽度增大,且该效应随绝热程度减小而增强。建议云滴谱宽度的参数化将垂直速度、云滴数浓度、云滴尺度和绝热程度等考虑在内。 | 朱磊 陆春松 高思楠 YUM Seong Soo | 2020 | 大气科学2020,44,3: | 11 |
| 2 | Comparison of the Bright Band Characteristics Measured by Micro Rain Radar (MRR) at a Mountain and a Coastal Site in South Korea显示文摘Data from a long term measurement of Micro Rain Radar (MRR) at a mountain site (Daegwallyeong,DG, one year period of 2005) and a coastal site (Haenam, HN, three years 2004–2006) in South Korea were analyzed to compare the MRR measured bright band characteristics of stratiform precipitation at the two sites. On average, the bright band was somewhat thicker and the sharpness (average gradient of reflectivity above and below the reflectivity peak) was slightly weaker at DG, compared to those values at HN. The peak reflectivity itself was twice as strong and the relative location of the peak reflectivity within the bright band was higher at HN than at DG. Importantly, the variability of these values was much larger at HN than at DG. The key parameter to cause these differences is suggested to be the difference of the snow particle densities at the two sites, which is related to the degree of riming. Therefore, it is speculated that the cloud microphysical processes at HN may have varied significantly from un-rimed snow growth, producing low density snow particles, to the riming of higher density particles, while snow particle growth at DG was more consistently affected by the riming process, and therefore high density snow particles. Forced uplifting of cloudy air over the mountain area around DG might have resulted in an orographic supercooling effect that led to the enhanced riming of supercooled cloud drops. | Joo-Wan CHA Ki-Ho CHANG Seong Soo YUM Young-Jean CHOI | 2009 | Advances in Atmospheric Sciences2009,26,2: | 8 |
| 3 | Development of genome engineering technologies in cattle: from random to specific显示文摘The production of transgenic farm animals(e.g., cattle) via genome engineering for the gain or loss of gene functions is an important undertaking. In the initial stages of genome engineering, DNA micro-injection into one-cell stage embryos(zygotes) followed by embryo transfer into a recipient was performed because of the ease of the procedure.However, as this approach resulted in severe mosaicism and has a low efficiency, it is not typically employed in the cattle as priority, unlike in mice. To overcome the above issue with micro-injection in cattle, somatic cell nuclear transfer(SCNT) was introduced and successfully used to produce cloned livestock. The application of SCNT for the production of transgenic livestock represents a significant advancement, but its development speed is relatively slow because of abnormal reprogramming and low gene targeting efficiency. Recent genome editing technologies(e.g.,ZFN, TALEN, and CRISPR-Cas9) have been rapidly adapted for applications in cattle and great results have been achieved in several fields such as disease models and bioreactors. In the future, genome engineering technologies wil accelerate our understanding of genetic traits in bovine and wil be readily adapted for bio-medical applications in cattle. | Soo-Young Yum Ki-Young Youn Woo-Jae Choi Goo Jang | 2018 | Journal of Animal Science and Biotechnology2018,9,2: | 5 |
| 4 | High heat loading performance of actively cooled W/Cu FGM-based components显示文摘A functionally graded material-based actively water-cooled tungsten-copper mockup with a dimension of 30 mm×30 mm×25 mm was designed and fabricated by infiltration-brazing method.The thicknesses of the pure W layer and W/Cu graded layer were 2 and 3 mm,respectively.High heat flux tests were performed on the mockup using an e-beam device.There is no damage occurring on the joint after heat loading at 5 MW/m2.The temperature on the pure W surface is less than 500°C after irradiation for 100 s at 5 MW/m2,while the temperature on the brazing seam/copper surface is around 200°C. | Zhang-jian Zhou Jun Tan Dan-dan Qu Hua Li Young-jin yum Hyun-woo Lim | 2011 | International Journal of Minerals,Metallurgy and Materials2011,18,4: | 5 |
| 5 | Old dogs,new trick:classic cancer therapies activate cGAS显示文摘The discovery of cancer immune surveillance and immunotherapy has opened up a new era of cancer treatment.Immunotherapies modulate a patient's immune system to specifically eliminate cancer cells;thus,it is considered a very different approach from classic cancer therapies that usually induce DNA damage to cause cell death in a cell-intrinsic manner.However,recent studies have revealed that classic cancer therapies such as radiotherapy and chemotherapy also elicit antitumor immunity,which plays an essential role in their therapeutic efficacy.The cytosolic DNA sensor cyclic GMP-AMP synthase(cGAS)and the downstream effector Stimulator of Interferon Genes(STING)have been determined to be critical for this interplay.Here,we review the antitumor roles of the cGAS-STING pathway during tumorigenesis,cancer immune surveillance,and cancer therapies.We also highlight classic cancer therapies that elicit antitumor immune responses through cGAS activation. | Seoyun Yum Minghao Li Zhijian J.Chen | 2020 | Cell Research2020,30,8: | 4 |

| 9 | Factors associated with refractory pain in emergency patients admitted to emergency general surgery显示文摘BACKGROUND: Oligoanalgesia in emergency departments (EDs) is multifactorial. A previousstudy reported that emergency providers did not adequately manage patients with severe paindespite objective findings for surgical pathologies. Our study aims to investigate clinical andlaboratory factors, in addition to providers’ interventions, that might have been associated witholigoanalgesia in a group of ED patients with moderate and severe pains due to surgical pathologies.METHODS: We conducted a retrospective study of adult patients who were transferred directlyfrom referring EDs to the emergency general surgery (EGS) service at a quaternary academic centerbetween January 2014 and December 2016. Patients who were intubated, did not have adequaterecords, or had mild pain were excluded. The primary outcome was refractory pain, which wasdefi ned as pain reduction <2 units on the 0–10 pain scale between triage and ED departure.RESULTS: We analyzed 200 patients, and 58 (29%) had refractory pain. Patients with refractory painhad signifi cantly higher disease severity, serum lactate (3.4±2.0 mg/dL vs. 1.4±0.9 mg/dL, P=0.001), and lessfrequent pain medication administration (median [interquartile range], 3 [3–5] vs. 4 [3–7], P=0.001), whencompared to patients with no refractory pain. Multivariable logistic regression showed that the number of painmedication administration (odds ratio [OR] 0.80, 95% confi dence interval [95% CI] 0.68–0.98) and ED serumlactate levels (OR 3.80, 95% CI 2.10–6.80) were signifi cantly associated with the likelihood of refractory pain.CONCLUSIONS: In ED patients transferring to EGS service, elevated serum lactate levelswere associated with a higher likelihood of refractory pain. | William Gilliam Jackson FBarr Brandon Bruns Brandon Cave Jordan Mitchell Tina Nguyen Jamie Palmer Mark Rose Safura Tanveer Chris Yum Quincy K.Tran | 2021 | World Journal of Emergency Medicine2021,12,1: | 2 |
| 10 | Acute amnesia during pregnancy due to bilateral fornix infarction: A case report显示文摘BACKGROUND Stroke is an important cause of maternal morbidity and mortality during pregnancy and puerperium.Isolated amnesia is a rare clinical symptom caused by ischemic stroke during pregnancy.We present the first documented case of acute amnesia during pregnancy due to bilateral fornix infarction.CASE SUMMARY A 32-year-old nullipara presented at 35 wk of gestation with acute amnesia and headache.Brain magnetic resonance imaging and angiography revealed acute infarction in the bilateral anterior fornix.There was no evidence of causative abnormality after extensive work-up,including for vascular abnormality,cardiac disease,coagulopathy,and pregnancy-related conditions.The patient was diagnosed with cryptogenic stroke.Aspirin was administered immediately,and the patient recovered fully without recurrence.CONCLUSION Acute isolated amnesia due to stroke is rare during pregnancy.Early diagnosis of stroke and immediate treatment prevent neurologic sequelae. | Min Jai Cho Dong-Ick Shin Moon-Ku Han Kyu Sun Yum | 2020 | World Journal of Clinical Cases2020,8,19: | 2 |
