Electrical contacts in monolayer Ga2O3 field-effect tansistors
No full textMonolayer (ML) Ga2O3 with wide bandgap and ultra-high electron mobility has gained extensive interests due to its great potential in next-generation electronic and solar-blind optoelectronic applications. Here, we perform a comprehensive investigation on the electronic properties of the ML Ga2O3 field-effect transistors (FETs) with different metal electrodes spanning a wide work function using energy band structure and quantum transport (QT) calculations. The results indicate all the investigated metals form n-type Ohmic contact with ML Ga2O3 in vertical direction, while high Schottky barrier heights (SBHs) exist for holes except for Sc due to its metallization and re-construction at the contact interface. In addition, the existence of tunneling barrier (TB) at the interface of ML Ga2O3/Ag, Au, Pd, and Pt systems reduce the electron injection efficiency to 20.09%, 13.03%, 34.70%, and 26.29%, respectively. Using a back-gated FET configuration, Al electrode exhibits the highest performance with Ohmic contact property and absence of tunneling barrier, thus is believed to act as the best candidate electrode material for ML Ga2O3 transistors. In addition, the results indicate that the current of ML Ga2O3 transistor is dominated by electrons rather than holes. Our study offers a theoretical foundation for the electrode selection for ML Ga2O3 devices.This work is supported by the National Natural Science Foundation of China (62004153), Key Research and Development Program of Shaanxi Province (2019ZDLGY16-01), Xi'an Key Laboratory of Intelligent Detection and Perception (201805061ZD12CG45), and Natural Science Foundation of Shaanxi science and Technology Department (021JM-432).

Comparison between a phenomenological approach and a morphoelasticity approach regarding the displacement of extracellular matrix
No full textPlastic (permanent) deformations were earlier, modeled by a phenomenological model in Peng and Vermolen (Biomech Model Mechanobiol 19(6):2525–2551, 2020). In this manusctipt, we consider a more physics-based formulation that is based on morphoelasticity. We firstly introduce the morphoelasticity approach and investigate the impact of various input variables on the output parameters by sensitivity analysis. A comparison of both model formulations shows that both models give similar computational results. Furthermore, we carry out Monte Carlo simulations of the skin contraction model containing the morphoelasticity approach. Most statistical correlations from the two models are similar, however, the impact of the collagen density on the severeness of contraction is larger for the morphoelasticity model than for the phenomenological model.Numerical Analysi
[[alternative]]The study of the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu
No full text[[abstract]]The main purpose of this study were to explore the relations between the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu. The researcher applied the questionnaire of “the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu “ and I drew 500 visitors as the research samples who participated in ocean sports in Peng-hu during August and September in 2005. The data collected from valid questionnaires were analyzed by descriptive statistics, Pearson’s product moment correlation, stepwise multiple regression analysis and canonical correlation analysis. The results are as followed:
1. The ocean sports in Peng-hu attracted visitors to a certain degree and the whole service quality is comfortable to them.
2. The relationship between the ocean sport’s attraction and service quality in Peng-hu was positive to a certain degree, and the higher service quality is, the greater ocean sport’s attraction in Peng-hu is.
3. Within each factors of the ocean sport’s attraction and the service quality, “the specialty of designing activity “and “the comfort of the environment “ had the best prediction to the loyalty of behavioral consequences; “advertisement and spread of the main activity” and “personal requirement” explain “better than any other factors.
4. The canonical correlation analysis of the study was the ocean sport’s attraction and service quality in Peng-hu have a high and positive correlation with the loyalty of behavioral consequences; the ocean sport’s attraction in Peng-hu has a moderate and positive correlation with the tendency of complaint of behavioral consequences.
Based on the results, we suggest the related organizations should:（1）strengthen the diversity of activity and develop package route of travel;（2）enforce the communication of information and promote the quality of complementary service;（3）integrate the resources and set up conservation area to build the continuous managing mold of ocean sport’s tourism.
For further research in the future: incorporate the follow-up issue of ocean sport’s tourism with profound interview and pay equal attention to qualitative research and quantitative research. Extending the subjects to related organization administrators、managers and dealers、local people and foreign tourist etc. and proceeding a comprehensive research.

This species was formerly attributed to Changa as the type species by Lee (2016), and the same author synonymized H. stellata Lee, 2009 with Changa sita (Distant, 1881) (Lee, 2016). In the present paper, we remove it to Haphsa based on morphological characterization and phylogenetic analysis (Fig. 4). Lee (2016) also transferred H. jsguillotsi (Boulard, 2005) to Changa, but we confirm it is a member of Haphsa (see below). Accordingly, Changa Lee, 2016 syn. n. is synonymized with Haphsa.Published as part of Wang, Siyue, Peng, Xiaodong & Wei, Cong, 2021, A review of the cicada genus Haphsa Distant, 1905 with the description of one new species from China (Hemiptera: Cicadidae) and a phylogenetic analysis of Haphsa and its allies, pp. 523-538 in Zootaxa 4991 (3) on page 530, DOI: 10.11646/zootaxa.4991.3.5, http://zenodo.org/record/504258
Mode-locked fiber laser of 3.5 μm using a single-walled carbon nanotube saturable absorber mirror
No full textWe report on a mid-infrared fiber laser that uses a single-walled carbon nanotube saturable absorber mirror to realize the mode-locking operation. The laser generates 3.5 µm ultra-short pulses from an erbium-doped fluoride fiber by utilizing a dual-wavelength pumping scheme. Stable mode-locking is achieved at the 3.5 µm band with a repetition rate of 25.2 MHz. The maximum average power acquired from the laser in the mode-locking regime is 25 mW. The experimental results indicate that the carbon nanotube is an effective saturable absorber for mode-locking in the mid-infrared spectral region
Right Turn, Left Turn Rethinking Chinese Christianity from 1945 to 1949 in the Spirit of the Second Vatican Council
No full textWhat is the Catholic Church's attitude toward socialism and communism? This is a historical question in that the answer changed over time. Drawing on the readings of the essays that appeared in the Catholic journal Yishi zhoukan ((sic) World Benefit Weekly), published in 1940s China, this article offers a special case with which the author wishes to shed light on the question. These essays reveal that at the historical juncture when, or right before, China fell to communist rule in 1949, the Chinese Catholic Church was showing a strong anticommunist stance, more so than its counterparts' in Europe, either in the past or at the time.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000319282700005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701HistoryAsian StudiesA&HCI0ARTICLE288-1044
[[alternative]]The Adjustability of International Marriage in Peng-Hu County Comparison with Indonesian and Vietnamese Brides
No full text[[abstract]]During the whole composing process of marriage, different races will broke out tough problems in adjustability. Since the influence of varied language and culture, it is difficult to adjust to each international marriage. Due to the developing imbalance in Peng-Hu, amounts of males lose their marriage. Under this serious marriage squeezing, they have no option but to elect international marriage matching center. They must look for their brides from Indonesia and Vietnam by this way. While immigrating to Peng-Hu, the diversity between immigratory and emigratory area, results in different obvious concepts in adjustability in their life. In this matching cooperation, however, causes a lot of leaving problems. Matching Centers match so many couples, maybe at first they really desire to match a great marriage. But in the end, they simply consider about if they could receive the high profit or not. Certainly, they play important roles between these international marriages. After entering the immigratory place, how to adjust and communicate with local citizen, it is worthy to be thought deeply about.
