 Retraction is the withdrawal of published article after it is found that the authors did not ensure integrity in conducting and reporting their research activities. The bibliometric information of 4716 document categorised as retractions in Science Citation Index, Web of Science was downloaded and analysed to understand trend, pattern and reasons of retraction. The results showed that retractions had increased during the ten-year period, 2008-2017. The main reasons for retractions were plagiarism, falsified data, manipulation of images and figures. It was also found that j

Abstract:
ABSTRACTArticles may be retracted when their findings are no longer considered trustworthy due to scientific misconduct or error, they plagiarize previously published work, or they are found to violate ethical guidelines. Using a novel measure that we call the “retraction index,” we found that the frequency of retraction varies among journals and shows a strong correlation with the journal impact factor. Although retractions are relatively rare, the retraction process is essential for correcting the literature and maintaining trust in the scientific process.

Abstract:
Retraction is one of the ways to filter low-quality academic publications. Over the last decade, the number of retracted articles from journals has been steadily growing around the world. Information about such articles can be found both on the websites of the retracting journals and in the databases that index these journals. In 2010, two doctors from the United States, Ivan Oransky and Adam Marcus, created an Internet resource – Retraction Watch (RW), which concentrates information obtained as a result of investigations of ethical misconduct leading to retraction of articles.

Abstract:
During upper gastrointestinal surgery, retraction of the liver plays an essential role in the visualization and creation of an optimal surgical field. Liver retraction may be problematic, particularly in obese patients. The use of conventional liver retractors requires additional skin incision and has the potential to cause pain as well as liver injuries. The present study is the first to evaluate the performance and safety of the LiVac Sling (Livac Pty Ltd, Melbourne, Australia) trocar-free retractor system in bariatric surgery patients.

Background: The ROTEM™ clot lysis index, describing the decrease in firmness of a clot with time, predicts mortality in various settings. The variability of the clot lysis index in surgical procedures and the involved pathophysiological mechanisms are unknown. We therefore compared pre- and postoperative clot lysis indices in liver transplantation (LTX) procedures, determined the eventual association with mortality, and investigated the mechanisms underlying decreased clot lysis index using inhibitors of fibrinolysis and clot retraction, respectively.

If X is a simply connected CW complex, then it has a unique (up to isomorphism) minimal Sullivan model. There is an important rational homotopy invariant, called the rational Lusternik–Schnirelmann of X, denoted cat0(X), which has an algebraic formulation in terms of the minimal Sullivan model of X. We study another such numerical invariant called the rational retraction index of X, denoted r0(X), which is defined in terms of the minimal Sullivan model of X and satisfies 0 ≤ r0(X) ≤ cat0(X). It was introduced by Cuvilliez et al. as a tool to estimate the rational Lusternik–Schnirelmann categor

AbstractGiven the previous chapters on topology and dynamical system theory, we can now provide a consistent treatment of topological obstructions to stability and stabilization. In particular, we will see how the retraction theory from Sect. 2.2 and the index results due to Bobylev, Krasnosel’skiĭ and Zabreĭko from Sect. 3.5 cover most of the existing results, conceptually. The current chapter focuses on the obstructions themselves and the next chapter highlights potential solutions.
