Abstract

This study focuses on a critical aspect of bridge engineering -- the evaluation of cable forces, paying particular attention to the cables that are internally constrained by elastic supports. Detecting these cable forces is important for the safety and stability of bridges. The practical problem introduces a novel mathematical challenge: how to effectively address string vibration equations with one or multiple internal elastic supports,~which remains a theoretical issue not fully solved in engineering. To tackle this, it is necessary to firstly establish an appropriate mathematical model and accurately define initial-boundary value problems. We then formulate the well-posedness of the solution using both classical and weak solution approaches, supplementing the existing numerical results available in engineering. Meanwhile, we attempt to use PINNs (Physics-Informed Neural Networks) instead of traditional FEM (Finite Element Method) in engineering. Consequently, in contrast to the classical solution method, we demonstrate that for a string with finite elastic supports, the weak solution method not only improves mathematical modeling efficiency but also simplifies the process of explaining the well-posedness of the solution.

Abstract

BackgroundOnline patient communities provide new channels for users to access and share medical information. In-depth study of users’ willingness to share information in online patient communities is of great significance for improving the level of information sharing among the patient community and the long-term development of communities. ObjectiveThe aim of this study was to build a model of factors affecting patients’ willingness to share medical information from the perspective of both positive and negative utilities. Specifically, we aimed to determine the influence of online information support and privacy concerns, as well as the moderating effect of disease severity and information sensitivity of different patients on their willingness to share. MethodsData from 490 users with experience in online patient communities were collected through a questionnaire survey, and structural equations were applied to empirically verify the model hypotheses. ResultsPrivacy concerns negatively affected the patients’ willingness to share information (P

Abstract

Abstract Photocontrollable luminescent molecular switches capable of changing emitting color have been regarded as the ideal integration between intelligent and luminescent materials. A remaining challenge is to combine good luminescence properties with wide range of wavelength transformation, especially when confined in a single molecular system that forms well-defined nanostructures. Here, we report a π-expanded photochromic molecular photoswitch, which allows for the comprehensive achievements including wide emission wavelength variation (240 nm wide, 400–640 nm), high photoisomerization extent (95%), and pure emission color (

Abstract

An increasing number of studies have demonstrated that potentially inappropriate medication (PIM) occurs commonly in elderly patients with cancer, with higher prevalence of PIM than general elderly, which may lead to adverse effects on prognosis of the patients. Therefore, it is necessary to conduct a systematic and comprehensive review of previous studies to provide support and reference for future studies. PubMed, CNKI and Wanfang Data were systematically searched to summarize and analyze the screen tools of PIM, prevalence of PIM, main drugs involved, influencing factors and the relationship between PIM and adverse outcomes. The results showed that the prevalence of PIM varied when different PIM screen tools were used in older patients with cancer, and the list of medications commonly used for supportive care that are of concern in older patients provided by the NCCN Guidelines for Older Adult Oncology (2020.v2) demonstrated advantages in providing individualized medication management for elderly patients with cancer. Polypharmacy, age, and comorbidities were significantly associated with the development of PIM. Benzodiazepines and analgesics are commonly used as high-risk drugs in elderly patients with cancer. PIM may be associated with higher mortality rates, drug interaction rates, adverse event rates, emergency and hospital readmission rates in elderly patients with cancer. It is hoped that this article will provide a reference for conducting studies related to PIM in elderly patients with cancer in China and provide support for promoting the safe and rational use of medication in elderly patients with cancer.
