This review highlights recent improvement in trifluoromethylene functionalization processes with CF3 reagents, includes: Togni’s, Umemoto’s, CF3SO2Cl, CF3I, Yagupol’skii-Umemoto, TMSCF3, Langlois (CF3SO2Na) and clarifies the several designing to result the corresponding trifluoromethylated products. In this article, the selective trifluoromethylation reactions with Togni’s reagents and their analogs are detailed, which work transition metals or photoactivated Ru or Ir catalysts as single electron giver to yield CF3 radical intermediate species. This issue is to introduce a draft of diverse reports, presenting the modern reaction collect and mechanics produced during the past five years. This task is demanded by the key protocol connected with the trifluoromethylation reactions, designing to sustain researchers a straight forward understanding of such reactions and to award information for further implements.

Promising Application

Healthcare is considered as one of the most promising application areas for artificial intelligence and analytics (AIA) just after the emergence of the latter. AI combined to analytics technologies is increasingly changing medical practice and healthcare in an impressive way using efficient algorithms from various branches of information technology (IT). Indeed, numerous works are published every year in several universities and innovation centers worldwide, but there are concerns about progress in their effective success. There are growing examples of AIA being implemented in healthcare with promising results. This review paper summarizes the past 5 years of healthcare applications of AIA, across different techniques and medical specialties, and discusses the current issues and challenges, related to this revolutionary technology. A total of 24,782 articles were identified. The aim of this paper is to provide the research community with the necessary background to push this field even further and propose a framework that will help integrate diverse AIA technologies around patient needs in various healthcare contexts, especially for chronic care patients, who present the most complex comorbidities and care needs.

Privileged Scaffold

3-Phenylcoumarins are a family of heterocyclic molecules that are widely used in both organic and medicinal chemistry. In this overview, research on this scaffold, since 2010, is included and discussed, focusing on aspects related to its natural origin, synthetic procedures and pharmacological applications. This review paper is based on the most relevant literature related to the role of 3-phenylcoumarins in the design of new drug candidates. The references presented in this review have been collected from multiple electronic databases, including SciFinder, Pubmed and Mendeley.

Biological Organisms

This review paper discusses aspects of hill country science-based soil fertility management advice given to farmers in the past on the use of fertiliser, principally superphosphate, on hill country farms. This shows that both pasture quantity and quality are improved with the application of the nutrients phosphorus (P) and sulphur (S) in superphosphate and that an unseen benefit of this is the increased food supply to soil biological organisms which also flourish under this management. The large potential for nitrogen (N) fertiliser application is explored and demonstrated. New thinking and technologies are allowing farmers to differentially apply variable rates and types of fertiliser nutrients by air to better match the growth potentials of contrasting hill country zones and so ensure that the investment in fertiliser will give the best financial returns possible. Keywords: soil fertility, hill country, differential application, variable rate

Transmission of video traffic over the Internet has grown exponentially in the past few years<br>with no sign of waning. This increasing demand for video services has changed user expectation of quality. Various mechanisms have been proposed to optimise the Quality of Experience (QoE) of end users’ video. Studying these approaches are necessary for new methods to be proposed or combination of existing ones to be tailored. We discuss challenges facing the optimisation of QoE for video traffic in this paper. It surveys and classifies these mechanisms based on their functions. The limitation of each of them is identified and future directions are highlighted.

Aerosol Radiative

&lt;p&gt;Aerosol radiative forcing plays an important role in the attribution of past climate changes, estimates of future allowable carbon emissions, and the assessment of potential geoengineering solutions. Substantial progress made over the past 40 years in observing, understanding, and modelling aerosol processes helped quantify aerosol radiative forcing, but uncertainties remain large.&lt;/p&gt;&lt;p&gt;In spring 2018, under the auspices of the World Climate Research Programme's Grand Science Challenge on Clouds, Circulation and Climate Sensitivity, thirty-six experts gathered to take a fresh and comprehensive look at present understanding of aerosol radiative forcing and identify prospects for progress on some of the most pressing open questions. The outcome of that meeting is a review paper, Bellouin et al. (2019), accepted for publication in Reviews of Geophysics. This review provides a new range of aerosol radiative forcing over the industrial era based on multiple, traceable and arguable lines of evidence, including modelling approaches, theoretical considerations, and observations. A substantial achievement is to focus on lines of evidence rather than a survey of past results or expert judgement, and to make the open questions much more specific.&lt;/p&gt;&lt;p&gt;This talk will present the key messages and arguments of the review and identify work that show promise for improving the quantification of aerosol radiative forcing.&lt;/p&gt;

This review paper marks the 70th anniversary of Current Sociology, the first journal founded by the International Sociological Association (ISA). The past seven decades have been a time of immense change within sociology and around the world, and the shifts within the structure and content of the journal mirror these transformations. Current Sociology today is a vastly different publication to the bibliography focused journal of 1952, and remains one of the top global sociology journals, and a proudly international publication. This short overview traces the history of Current Sociology across the decades, highlighting the work of the editors in guiding the development of the journal, and providing a glimpse into the development of the discipline, and the social developments of the past 70 years.

Digital technologies are now actively influencing all spheres of material and spiritual life of a person and society as a whole. Integration with information technology allows not only the economy to automate business processes, reduce resource costs, increase the competitiveness of industries and increase the efficiency of various tasks, but also optimizes educational processes related to training, professional competency, information and, ultimately, digital services change our way of life. As part of this review paper, the authors carry out a source analysis of scientific articles published in the journal "Kant" for the past two years on the issue of digitalization in the modern social and humanitarian space in various scientific aspects.
