Similarity assessment by multivariate statistics method based on the distance between biosimilar and originator

Abstract: The development of biosimilar products or follow-on biologics has been flourishing in recent years because of their lower price than the originators. In this study, a multivariate data analysis method based on JMP software was proposed to assess the glycosylation pattern similarity of antibody candidates from different conditions in optimization experiments with a reference. A specific distance was generated by this method and indicated the glycoform similarity between the biosimilar and the reference. This method can be applied to analyze the similarity of other physicochemical and functional characteristics between follow-on biologics and originators. Then, the design of experimental methods can be realized to optimize the conditions of cell culture to attain similar antibody candidates. A higher concentration of GlcNAc added to the basal media made the glycan of the antibody more similar to the glycan of the reference in this study.

Post-traumatic epilepsy: its complications and impact on occupational rehabilitation--an epidemiological study from India.

Abstract: The objective of this study was to assess the prevalence of seizure disorder, neuropsychiatric disorders and reproductive outcome of employees with post-traumatic epilepsy (PTE) and their effect on occupational rehabilitation. A case-comparison group study design was used to compare 30 subjects with PTE with (1) 129 non-PTE and (2) 55 non-PTE matched control employees. The 55 non-PTE matched controls were selected from the 129 non-PTE employees on the basis of age, age at onset of seizure, age at marriage and length of employment. The PTE group had a lower fertility rate than the controls and more neuropsychiatric disorders and seizure disability. PTE employees were more occupationally rehabilitated than non-PTE employees (p = 0.033). Of the 30 PTE subjects, thirteen who were rehabilitated by placement had more seizure disability (p = 0.007) and a higher fertility rate (p = 0.018). High prevalence of seizure disability and increased fertility rate among the placed PTE employees suggested that there might be some association between severity of seizures and increased production of live offspring and work placement. Work suitability or placement should not be judged on clinical assessment only but psychosocial seizure assessment, disability evaluation and other psychometric tests which are of equal importance.

Fake or Fact? Theoretical and Practical Aspects of Fake News

Abstract: The phenomenon of fake news is nothing new. It has been around as long as people have had a vested interest in manipulating opinions and images, dating back to historical times, for which written accounts exist and probably much beyond. Referring to it as post-truth seems futile, as there’s probably never been an era of truth when it comes to news. More recently, however, the technical means and the widespread use of social media have propelled the phenomenon onto a new level altogether. Individuals, organizations, and state-actors actively engage in propaganda and the use of fake news to create insecurity, confusion, and doubt and promote their own agenda – frequently of a financial or political nature. We discuss the history of fake news and some reasons as to why people are bound to fall for it. We address signs of fake news and ways to detect it or, to at least become more aware of it and discuss the subject of truthfulness of messages and the perceived information quality of platforms. Some examples from the recent past demonstrate how fake news has played a role in a variety of scenarios. We conclude with remarks on how to tackle the phenomenon – to eradicate it will not be possible in the near term. But employing a few sound strategies might mitigate some of the harmful effects.

A Comparative Study of EDD and PM-EDD in Producing Holes in Inconel 718 Alloy

Abstract: In recent times, aerospace, chemical industries and nuclear plant have usually used Inconel 718 alloy because of its excellent mechanical and chemical properties at elevated temperatures. It falls under the category of difficult-to-cut materials due to its high toughness, poor thermal conductivity and high hardness. The set-ups for electric discharge drilling (EDD) and powder-mixed electric discharge drilling (PM-EDD) were developed, and experiments were conducted on them separately. This research shows a comparative study amid producing holes by EDD and PM-EDD in Inconel 718 alloy workpiece with copper tool electrode. SiC was used as an abrasive powder because of its better thermal conductivity in order to get properly mixed with dielectric in a separate tank. Output response was assessed in the form of material removal rate, under the influence of discharge current, duty factor, pulse-on-time and tool speed, as the input parameters.

Continuous models of affect from text using n-grams

Abstract: We propose a method of affective text analysis and modeling that is capable of generating continuous valence ratings at the sentence level starting from word and multi-word term valence ratings. Motivated from the language modeling literature, a back-off algorithm is employed to efficiently fuse the valence of single-word and multi-word terms. Specifically, a term detection criterion is used to select the appropriate n-gram terms, starting with bigrams and potentially backing off to unigrams. Term affective ratings are generated by a lexicon expansion method, using semantic similarity estimates computed on a large web corpus. The proposed framework provides state-of-the art results in the sentence level SemEval'07 task of news headline polarity detection, reaching an accuracy of 75%.
