In port dock engineering, high-piled wharves represent one of the primary structural forms. Damage to the foundation piles is a common issue, influenced by external loads such as impact forces during vessel berthing, slope deformations, and operational loads. This study focuses on the Jungong Road Wharf in Shanghai, utilizing FLAC 3D version 6.0 to conduct dynamic calculations under ship impact loading. The dynamic responses of the structure were analyzed, and various internal forces were extracted during the impact event. By combining concrete cracking failure criteria and fatigue damage theories, the effects of ship collisions on the cracking damage of high-piled wharf structures under different scenarios were assessed. Additionally, the applicability of modal flexibility in high-piled wharf scenarios was evaluated through finite element simulations. The results indicate that the dynamic amplification factor caused by dynamic loading is approximately 1.5, underscoring the necessity of considering this effect in the design and impact analysis of high-piled wharves. The impact loading significantly influences the bending moments of the piles, with inclined piles showing the greatest sensitivity. When a designed ship model collides with the high-piled wharf structure at a speed of 0.2 m/s, the tensile stress in the inclined piles reaches 87% of the ultimate tensile strength of the reinforcement. The impact loading has a relatively minor effect on the axial forces of the piles, a limited influence on the bending moments of the beams, but a considerable impact on the axial forces of the beams. Berthing by oversized vessels and unexpected incidents can lead to more severe damage to high-piled wharf structures. In the finite element simulations, modal flexibility effectively identified the locations of damage, with greater changes in modal flexibility correlating with increased damage severity.

With rapid development and modernization of today's society, the resource inequality between rural and urban areas has enlarged, especially regarding adolescents' mental health education. In order to provide alternative to adolescents with limited resources, this study targets test anxiety as example, aiming to explore the effectiveness of online mindfulness training in alleviating students' test anxiety through a quasi-experiment. This study recruited youths from 12 to 18 years old and used their pre-test/post-test data on 186 trained participants (M age = 14.85, 57.5% male) and 217 propensity-score matched controls (M age = 15.35, 53% male). After careful analysis, the results proved the effectiveness of online mindfulness training in reducing test anxiety and showed that the online training was more beneficial for students with serious interpersonal problems. This study further provided implications for the use of technology in mental health education, promoting the care of psychological well-being in rural areas. [ABSTRACT FROM AUTHOR]

A photonic instantaneous microwave frequency measurement scheme based on frequency-to-time mapping and channelization is proposed. An unknown signal is divided into four channels and mixed with a broadband linear frequency-modulated signal. The frequency information is converted to the time domain, and the frequency measurement range has been expanded due to channelization. A simulation system has been constructed to demonstrate the effectiveness of the proposed method. A proof-of-concept experimental result shows that the frequency measurement errors can be kept in 20 MHz with a 10 MHz resolution, and the frequency measurement range is 1 GHz to 39 GHz.

Co-innovation is a new paradigm and a new hot spot in the field of technological innovation. This study uses bibliometric analysis and CiteSpace to analyze the co-innovation related literature published at domestic and abroad during 2010-2022 to explore the current status and development trend of co-innovation research. The research results show that co-innovation research at domestic and abroad is developing rapidly and increasingly becoming a research hotspot in the field of technological innovation. Compared with foreign scholars who have begun to quantify and case study the technological paths of co-innovation, domestic research still mainly relies on qualitative methods to theoretically explore the institutional mechanism of co-innovation, which can hardly meet the development needs of co-innovation policy and practice. Therefore, this study proposes future research directions for co-innovation in four major aspects: mechanism of action, network model, empowerment mechanism and governance mechanism. As the first systematic study of co-innovation literature in China and abroad, this study has important theoretical significance and practical value.

Aqueous zinc (Zn)-ion batteries (AZIBs) present safe and environmentally friendly features thereby emerging as an attractive energy storage device. The V2O5-based cathodes are promising because of their high theoretical capacity and energy density. However, insufficient interlayer distance, easy dissolution and structural collapse due to irreversible crystalline phase transition limit the development of V2O5 cathodes in AZIBs. Herein, doubly modified V2O5-based cathode which was in-situ intercalated by polyaniline (PANI) and composited with MXene (Ti3C2Tx) (denoted PVM) were synthesized by one-step method for the first time. The in situ intercalation of PANI provides a channel for the rapid diffusion of Zn2+ and the heterogeneous structures effectively promote charge transfer and enable structural integrity of cathode during cycling. Meanwhile, the conductivity of PVM electrode is greatly improved. Specifically, the PVM electrode shows a superior rate performance of 82 mAh·g−1 after 2000 cycles at 10 A·g−1. And it shows high pseudocapacitance behavior (80.23% capacitor contribution ratio at 0.1 mV·s−1). A novel method of intercalation composite modification for the cathode is proposed, which provides fundamental guidance for the development of high-performance cathodes for AZIBs.

Men and women living in rural communities of the United States (US) are less likely than those in urban or suburban communities to be up to date with cancer screenings. Delayed screening contributes to later stage at diagnosis and higher cancer mortality for individuals living in rural areas. These effects may be compounded in some rural subpopulations (e.g. migrant and seasonal farmworkers). This systematic review examines educational interventions aimed at increasing colorectal, breast, prostate, oral, and/or cervical cancer screening in the rural US, with special consideration for the farmworker subpopulation. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, our systematic literature review employed the following databases: Ovid MEDLINE, CINAHL Complete, Embase, and Web of Science. Search terms included, but were not limited to 'rural,' 'cancer screening,' 'farmworker,' and 'cancer prevention.' Eligible studies featured an educational intervention implemented in agricultural or rural US settings with a cancer screening behavioral outcome, male and/or female participants, and were published in English between 2002 and 2020. Article screening and data extraction were conducted by two independent reviewers. Twenty-six articles were eligible. Of the six studies focused on the farmworker population (n=2,732), 61.75% of participants reported Hispanic ethnicity. Of the sixteen studies on unspecified rural communities reporting participant race/ethnicity (n=10,442), 39.29% reported Black/African American race. Efficacious interventions included culturally-targeted educational materials, lay health advisors (LHAs), and components that addressed practical barriers (e.g. financial or logistical). Results demonstrate the value of LHAs and targeted education to increase screening for multiple cancer types in rural communities. Prospective research should incorporate and facilitate access to screening and provider-level and/or organizational-level interventions to increase overall impact.
