    Biography of Lin Wen Zhong Gong has another way to call, that is Judge Lin. The leading character is Lin Ze-Xu. This book is based on functionary experience of Lin Ze-Xu, with the captivating plots of court case, helping by highly skilled military attach\uc3\ua9s and chivalrous knights, and the history facts of Opium War. It makes Lin Ze-Xu\ue2s Confucian temperament and tragic mood more, also contrasts with author\ue2s sorrow and furiousness for the politics at the time. History, court case, martial arts\ue2\ua6\ue2\ua6etc. are essence of this book and it broadens the way of this writing style. The topic of the thesis is \ue2An Analysis of Judge Lin\ue2. The following thesis will be divided into six different chapters. The introduction is Chapter one of the thesis, which is including researching motive and purpose, literature review of predecessors, researching version by existing information, raising questions, choosing research methods and arranging chapters. In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is.

    Predicting fracture energies and crack-tip fields of soft tough materials

    Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials. Here, we report a scaling theory that accounts for synergistic effects of intrinsic fracture energies and dissipation on the toughening of soft materials. We then develop a coupled cohesive-zone and Mullins-effect model capable of quantitatively predicting fracture energies of soft tough materials and strain fields around crack tips in soft materials under large deformation. The theory and model are quantitatively validated by experiments on fracture of soft tough materials under large deformations. We further provide a general toughening diagram that can guide the design of new soft tough materials.United States. Office of Naval Research (N00014-14-1-0528)Massachusetts Institute of Technology.

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    We have investigated the potential energy curves (PECs) of the LiN heteronuclear diatomic molecule, including its ionic species LiN+ and LiN−, using explicitly correlated multi-reference configuration interaction (MRCI-F12) calculations in conjunction with the correlation consistent quintuple- basis set. The effect of core–valence correlation, scalar relativistic effects, and the size of the basis sets has been investigated. A comprehensive set of spectroscopic constants determined based on the above-mentioned calculations are also reported for the lowest electronic states and all systems, including dissociation energies, harmonic and anharmonic vibrational frequencies, and rotational constants. Additional parameters, such as the dipole moments, equilibrium spin-orbit constants, excitation energies, and rovibrational energy levels, are also documented. We found that the three triplet states of LiN, namely, X 3∑−, A 3Π, and 2 3∑−, exhibit substantial potential wells in the PEC diagrams, while the quintet states are repulsive in nature. The ground state of the anion also shows a deep potential well in the vicinity of its equilibrium geometry. In contrast, the ground and excited states of the cation are very loosely bound. Charge transfer properties of each of these states are also analyzed to obtain an in-depth understanding of the interatomic interactions. We found that the core–valence correlation has a substantial effect on the calculated spectroscopic constants.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Atmospheric Remote Sensin

    Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply

    No full text
    This reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.

    Tough and tunable adhesion of hydrogels: experiments and models

    No full text
    As polymer networks infiltrated with water, hydrogels are major constituents of animal and plant bodies and have diverse engineering applications. While natural hydrogels can robustly adhere to other biological materials, such as bonding of tendons and cartilage on bones and adhesive plaques of mussels, it is challenging to achieve such tough adhesions between synthetic hydrogels and engineering materials. Recent experiments show that chemically anchoring long-chain polymer networks of tough synthetic hydrogels on solid surfaces create adhesions tougher than their natural counterparts, but the underlying mechanism has not been well understood. It is also challenging to tune systematically the adhesion of hydrogels on solids. Here, we provide a quantitative understanding of the mechanism for tough adhesions of hydrogels on solid materials via a combination of experiments, theory, and numerical simulations. Using a coupled cohesive-zone and Mullins-effect model validated by experiments, we reveal the interplays of intrinsic work of adhesion, interfacial strength, and energy dissipation in bulk hydrogels in order to achieve tough adhesions. We further show that hydrogel adhesion can be systematically tuned by tailoring the hydrogel geometry and silanization time of solid substrates, corresponding to the control of energy dissipation zone and intrinsic work of adhesion, respectively. The current work further provides a theoretical foundation for rational design of future biocompatible and underwater adhesives.United States.

    [[abstract]]A Study on the Relation of the Citizen’s SubjectiveI Impression on the Spouses from Mainland China and Vietnam and Community Educational Policies in Shu Lin City in Taipei ounty. Abstract By:Chou chen- tsung Advisor:Lin en-chung The purpose of this research is to understand the current situation of the citizen’s subjective impressions on the spouses from Mainland China and Vietnam in Shu Lin City. The survey is carried out by self-designed questionnaires. The parents of the students in 10 ele mentary schools of Shu Lin City were taken as samples, 1000 que stionnaires were released, in which 825 effective copies were responded and returned (reaching a 93.0% share of all return questionnaires). The methods for analyzing the data are adopted from SPSS Statistic Software, which includes avera ges, standard deviation,t-test,ANOVA…etc to analyze.The main findings are as below: 1. The subjective impression of Shu Lin citizens on the Mainland spouses tends to be “ordinary” to “slightly good.” 2. Regarding the subjective impression of Shu Lin citizens on the Mainland spouses, there is a significant difference on the four out of six different variants, which are gender, occupations, marital status, and their experience of contacting Mainland China spouses. 3. The subjective impression of Shu Lin citizens on the Vietnamese spouses tends to be “ordinary”to “slightly good.” 4. Regarding the subjective impression of Shu Lin citizens on the Vietnamese spouses, there is a significant difference on the three out of six different variants, which are occupations, marital status, and educational background. 5. There is a significant difference on the citizens’ subjective impres sion between the spouses from Mainland China and those from Vietnam. “Focus Group Interview” was also practiced to enrich the study. Based on the research result, some suggestions regarding the effective community educational policies are proposed. 1.Publicize the positive impressions of Shu Lin citizens toward the spouses from Mainland China and Vietnam. 2.More researches and studies should be done by th government and the academic institutes in order to facilitate the positive understanding. 3.Encourage the positive reports from the media which should be carefully regulated by the government and the non-gover nmental organizations. 4.For schools, enhance multicultural teaching environment;for the government, host more multicultural exhibitions about the spouses from Mainland and Vietnam. 5.Make good use of the resources from schools and communities to popularize the idea of “multicultural community educati on” as well as to facilitate the integration of different races. 6.The spouses from Mainland and Vietnam should learn actively and positively to adapt themselves to the lifestyles of the ir family and the community; therefore, they are able to gain more positive interaction and feedback from the peoplein the community. Key words: Mainland China spouses, Vietnamese spouses, Transnational marriage, Subjective impression
