In this paper, we study the existence and uniqueness of a positive solution for the singular nonlinear fractional differential equation boundary value problem. Our analysis rely on a fixed point theorem in partially ordered sets. As an application, an example is presented to illustrate the main results.

Tax Cuts, Firm Growth, and Worker Earnings : Evidence from Small Businesses in Canada

( Yige Duan ),( Terry S. Moon ) 한국금융연구원 2023 금융연구 working paper Vol.2023 No.5

This paper assesses the effects of corporate tax reductions for small businesses on their growth and employee earnings. Following a 2014 reform in Quebec, Canada, firms that received tax cuts increase their employment, payrolls, and capital stock by 1.7 percent, 2.3 percent, and 3.2 percent, respectively, relative to unaffected firms. In turn, these firms experience 5.2 percent, 0.4 percentage points, and 890 dollars increases in their sales, profit margins, and EBITDA per worker. Furthermore, annual earnings increase by 1.3 percent for workers in treated firms relative to workers in control firms. We estimate that workers without ownership in their own firms bear about a third of corporate tax burdens, and combined workers (with or without ownership) bear about three quarters of the tax burdens. Additionally, the effects are larger for firms and workers in high-growth and high-tech industries, suggesting a cash-flow channel playing an important role behind our results. Taken together, these findings suggest that tax incentives designed for small businesses may lead to significant increases in their growth and worker earnings, and targeting a specific sector or industry when designing corporate tax cuts may be an effective way to stimulate growth and employment in the economy.

중국의 공익프로그램 메시지에 의한 대리경험이 기부의도에 미치는 영향: 감정이입의 매개효과를 중심으로

유이거 ( Yige Liu ) 사단법인 아시아문화학술원 2020 인문사회 21 Vol.11 No.6

본 연구의 목적은 중국 공익 프로그램에서 시청자가 얻는 대리경험이 기부의도에 미치는 영향 및 감정이입의 매개효과를 탐색하는 것이다. 이를 위해 온라인 전문웹사이트인 『问卷星』을 통해 중국인을 대상으로 설문조사를 하여 분석하였다. 연구결과로는 첫째, 대리경험이 기부자 감정이입, 감정이입이 기부의도, 대리경험이 기부의도에 미치는 인과관계는 긍정적이고 유의미함으로 나타났다. 둘째, 기부자 대리경험 변인이 기부의도 변인에 미치는 매개효과는 유의미함이 검증되었다. 이에 따라 대리학습 이론을 출발하여 기부 문화와 커뮤니케이션 이론을 결합시킬 수 있다는 이론적 시사점과 실제공익 프로그램의 제작 및 모금 효과를 향상시키는 실무적 시사점이 제시되었다. 다만 본 연구는 연령대 차이, 프로그램 내용 세분화, 대리경험의 다각화 분석 등의 한계점을 지니고 있어 향후 심층 분석을 진행할 필요성이 있다. The purpose of this study is to explore the effect of the vicarious experience gained by viewers on the Chinese TV public-service program on donation intention and the mediating effect of empathy. For the study, a survey was conducted and analyzed on Chinese people through the online specialized website ‘wjx.cn.’ The main results of this paper are as follows: First, the effect of vicarious experience on empathy, vicarious experience on donation intention, empathy on donation intention is analysed the positive affect. Secondly, the mediated effect of the empathy is statistically to be significant. Based on the results of this study, the theoretical and practical implications starting from vicarious learning theory is to combine communication theory and donation culture and inspire active multidimensional donation programs. However, this research has limitations such as age difference, program content segmentation, and diversification of vicarious experience, so it is necessary to design in-depth anaylsis program in the future.

도시의 3차원 물리적 환경변수와 지표온도의 관계 분석

Li, Yige,이수기,한재원 대한국토·도시계획학회 2019 國土計劃 Vol.54 No.2

도시화와 인간 활동의 증가로 인한 기온상승은 기후변화로 인해 더욱 가속화되고 있으며, 이로 인해 인명 피해 및 사회 경제적피해가 급증하고 있다. 이는 도시의 기온 상승이 도시 거주민의생명에 중요한 부분을 차지하고, 기온 상승의 원인과 이로 인해발생하는 환경 변화에 대한 이해와 대책 마련이 시급함을 의미한다. 한편, 일반적으로 도시 중심부의 높은 접근성은 지대를 상승시키는 원인이 되며, 이러한 높은 지대에 부응하기 위하여 집약적인 토지이용이 요구된다. 그 결과 도시 중심부에는 초고층 복합건물이 위치하게 되고, 상대적으로 지대가 낮은 도시 외곽지역에는 저층, 단일 용도의 건물이 주로 분포하게 된다. 그러나 최근 공동주택의 고층화와 대형 복합 쇼핑몰의 확산으로 인해 건물의 고층화와 대형화가 외곽 지역으로 점차 확대되고 있다. 이로 인한대도시지역의 녹지감소와 불투수면의 증가는 지표온도 상승에영향을 미치고 나아가 도시열섬현상의 심화를 가져올 수 있다. 그러나 인간 활동의 결과인 건조환경(built environment)에따른 지표온도 변화와 지표온도에 영향을 미치는 3차원 물리적환경 요인에 대한 연구는 그 필요성에 비하여 부족한 실정이다. 따라서 본 연구는 지표면 온도의 분포와 지표온도에 영향을 미치는 3차원 물리적 환경 구성 요소와의 관계를 규명하고, 이를 통해향후 지표온도와 장기적으로 도시열섬 저감을 위한 도시계획 및설계요소를 제시하고자 한다.

The Soft Material Obtained from an Europium (III)-Containing Ionic Liquid

Huifang Shao,Yige Wang,Dan Li 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.3

The addition of organic ligand (β-diketone or heterocyclic compound) to the europium (III)-containing ionic liquid resulted in bright luminescent soft materials with the molar ratio of europium/ionic liquid (IL)/ligand being 1:3:1 that exhibit bright red light under UV lamp. The luminescent properties such as emission features and lifetime of ^(5)D_0 Eu^(3+) excited level are dependent on the organic ligands. The materials were characterized by FT-IR and luminescence spectroscopy. The data shows that at least parts of the ILs (carboxylic acid) are replaced with β-diketone ligand rather than the formation of europium complex with the molar ratio of Eu^(3+):IL: ligand being 1:3:1, while no ILs could be replaced by the heterocyclic ligand such as Bpy and Phen.

Distributed Cubature Kalman Filter with Performance Comparison for Large-scale Power Systems

Yibing Sun,Yige Zhao 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.3

This paper studies a distributed cubature Kalman filter algorithm for the dynamic state estimation of a large-scale power system, which is interconnected and consists of some sub-areas. Using the hybrid measurements, each subsystem runs the proposed algorithm independently and in parallel to forecast and estimate its local state, which helps in reducing the whole execution time and the communication load without a central coordinator. The edge measurements and the exchanged information with the neighboring subsystems are utilised to correct the local state estimation of each subsystem, which makes this algorithm improve some known methods in literature. Simulation results of the IEEE 118-bus system are provided to demonstrate the performance of the proposed algorithm by comparing it with the distributed methods based on the extended Kalman filter and unscented Kalman filter.

The Soft Material Obtained from an Europium (III)-Containing Ionic Liquid

Shao, Huifang,Wang, Yige,Li, Dan Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.3

The addition of organic ligand (${\beta}$-diketone or heterocyclic compound) to the europium (III)-containing ionic liquid resulted in bright luminescent soft materials with the molar ratio of europium/ionic liquid (IL)/ligand being 1:3:1 that exhibit bright red light under UV lamp. The luminescent properties such as emission features and lifetime of $^5D_0$ $Eu^{3+}$ excited level are dependent on the organic ligands. The materials were characterized by FT-IR and luminescence spectroscopy. The data shows that at least parts of the ILs (carboxylic acid) are replaced with ${\beta}$-diketone ligand rather than the formation of europium complex with the molar ratio of $Eu^{3+}$:IL: ligand being 1:3:1, while no ILs could be replaced by the heterocyclic ligand such as Bpy and Phen.

Solvability for a class of nonlinear fractional differential equations with parameters

Yuanyao Pan,Xinyi Hou,Yige Zhao 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10

This paper investigates the existence of positive solutions for the boundary value problem of nonlinear fractional differential equations with parameters. By using the properties of the Green function and Guo-Krasnosel’ skii fixed point theorem, the eigenvalue intervals of boundary value problem of fractional differential equation are studied and some sufficient conditions for the existence and nonexistence of at least one or two positive solutions for the boundary value problem are obtained. As an application, an example is presented to illustrate the main results.

Huang, Kuan-lin,Mashl, R. Jay,Wu, Yige,Ritter, Deborah I.,Wang, Jiayin,Oh, Clara,Paczkowska, Marta,Reynolds, Sheila,Wyczalkowski, Matthew A.,Oak, Ninad,Scott, Adam D.,Krassowski, Michal,Cherniack, And Elsevier 2018 Cell Vol.173 No.2

<P><B>Summary</B></P> <P>We conducted the largest investigation of predisposition variants in cancer to date, discovering 853 pathogenic or likely pathogenic variants in 8% of 10,389 cases from 33 cancer types. Twenty-one genes showed single or cross-cancer associations, including novel associations of <I>SDHA</I> in melanoma and <I>PALB2</I> in stomach adenocarcinoma. The 659 predisposition variants and 18 additional large deletions in tumor suppressors, including <I>ATM</I>, <I>BRCA1</I>, and <I>NF1</I>, showed low gene expression and frequent (43%) loss of heterozygosity or biallelic two-hit events. We also discovered 33 such variants in oncogenes, including missenses in <I>MET</I>, <I>RET</I>, and <I>PTPN11</I> associated with high gene expression. We nominated 47 additional predisposition variants from prioritized VUSs supported by multiple evidences involving case-control frequency, loss of heterozygosity, expression effect, and co-localization with mutations and modified residues. Our integrative approach links rare predisposition variants to functional consequences, informing future guidelines of variant classification and germline genetic testing in cancer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 871 predisposition variants/CNVs discovered in 8% of 10,389 cases of 33 cancers </LI> <LI> Pan-cancer approach identified shared variants and genes across cancers </LI> <LI> 33 variants affecting activating domains of oncogenes showed high expression </LI> <LI> 47 VUSs prioritized using cancer enrichment, LOH, expression and other evidence </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>
