The objective of this study was to determine whether consent forms in oncology clinical trials of commercially available treatments inform subjects that they may be able to obtain the treatments being investigated without participating in research. We acquired consent forms from a random sample of U.S. oncology clinical trials in the ClinicalTrials.gov database. We then examined a subgroup of the sample consisting of studies in which the treatments under investigations were commercially available. Less than 20% of the consent forms in (...) that group disclosed to subjects that they may be able to obtain the treatment being investigated without participating in the study . Our results suggest that potential research subjects are frequently not informed about important alternatives to research participation in studies involving commercially available treatments, which is a violation of both ethical and regulatory standards.

Through the recognition of ocean sediment sonar images, the texture in the image can be classified, which provides an important basis for the classification of ocean sediment. Aiming at the problems of low efficiency, waste of human resources, and low accuracy in the traditional manual side-scan sonar image discrimination, this paper studies the application of image recognition technology in sonar image substrate texture discrimination, which is popular in many fields. At the same time, considering the scale complexity, diversity, multisources, and (...) small sample characteristics of the marine sediment sonar image texture, the transfer learning is introduced into the image recognition, and the K-means clustering algorithm is used to reset the prior frame parameters to improve the speed and accuracy of image recognition. Through the experimental comparison between the original model and the new model based on transfer learning, the AP value of the yolov3 model based on transfer learning can reach 84.39%, which is 0.97% higher than that of the original model, with considerable accuracy and room for improvement; it takes less than 0.2 seconds. This shows the applicability and development of image recognition technology in texture discrimination of bottom sonar images. (shrink)

Dialectics is essentially the method or logos in which categories of forms are combined to explain things. Dialectics was developed because reason faces difficulties in grasping the sensible world. Practical wisdom is knowledge about some things or certain person or persons because of its variable objects. But it is not entirely specific or only about a particular thing and without universality in any sense. As one kind of dialectics, it combines various elements to accord with the right logos, similar to (...) the way in which various forms are combined in theory. Therefore practical wisdom as a combination or polymerization of elements can be regarded as another kind of logic, namely practical logic or dialectics. (shrink)

There are many Chinese versions of The Communist Manifesto and all of them had problems with the translation of foreign concepts and words, which triggered debates for years. One of the most interesting questions in the debates on the translation of the Manifesto is how to translate Assoziation / “association” and how Marx understood this concept.

This article reports on the evolution of breakdance. Given the inclusion of breakdancing in the 2024 Olympic Games in Paris, France, scholars have generated substantial international research related to breakdance teaching in recent years. However, few researchers have focused on the impact of formal formative assessment on breakdance teachers’ teaching and students’ learning. We wish to contribute to the quality of breakdance teaching and learning by identifying the positive impact of recent research on formative assessment on student learning and designing (...) a formal formative assessment task related to breakdance. This article lays out a framework of formal formative assessment tasks and identifies the positive impact of formative assessment on dance education. Although our work is far from perfect, it does provide a general methodological framework for assessing breakdance students’ abilities in formal educational settings. (shrink)

In this paper, the stability and stabilization issues for a class of delayed neural networks with time-varying hybrid impulses are investigated. The hybrid effect of two types of impulses including both stabilizing and destabilizing impulses is considered simultaneously in the analysis of systems. To characterize the occurrence features of impulses, the concepts of average impulse interval and average impulse strength are employed. Based on the analysis of stability, a pinning impulsive controller which can ensure the global exponential stability of the (...) studied neural networks is designed by pinning a small fraction of neurons. Finally, two numerical examples are given to illustrate the effectiveness of the proposed control schemes for delayed neural networks with hybrid impulses. (shrink)
