    Will This Paper Increase Your h-index? Scientific Impact Prediction

    Scientific impact plays a central role in the evaluation of the output of scholars, departments, and institutions. A widely used measure of scientific impact is citations, with a growing body of literature focused on predicting the number of citations obtained by any given publication. The effectiveness of such predictions, however, is fundamentally limited by the power-law distribution of citations, whereby publications with few citations are extremely common and publications with many citations are relatively rare. Given this limitation, in this work we instead address a related question asked by many academic researchers in the course of writing a paper, namely: "Will this paper increase my h-index?" Using a real academic dataset with over 1.7 million authors, 2 million papers, and 8 million citation relationships from the premier online academic service ArnetMiner, we formalize a novel scientific impact prediction problem to examine several factors that can drive a paper to increase the primary author's h-index. We find that the researcher's authority on the publication topic and the venue in which the paper is published are crucial factors to the increase of the primary author's h-index, while the topic popularity and the co-authors' h-indices are of surprisingly little relevance. By leveraging relevant factors, we find a greater than 87.5% potential predictability for whether a paper will contribute to an author's h-index within five years. As a further experiment, we generate a self-prediction for this paper, estimating that there is a 76% probability that it will contribute to the h-index of the co-author with the highest current h-index in five years. We conclude that our findings on the quantification of scientific impact can help researchers to expand their influence and more effectively leverage their position of "standing on the shoulders of giants."Comment: Proc. of the 8th ACM International Conference on Web Search and Data Mining (WSDM'15

    Thiazolidinediones (TZDs) are a new class of antidiabetic drugs, having an insulin sensitizing effect in patients with type 2 diabetes. We report here the synthesis A series of thirteen 2,4-thiazolidinedione derivatives. The 2,4-thiazolidinedione ring\u27s fifth position was used as a site for Knoevenagel condensation to generate the compounds listed in the title. The synthesised derivatives were characterised using a variety of physicochemical and spectral analyses, including IR, Mass, 1H-NMR, 13C-NMR, and elemental analysis. By using the carrageenan-induced rat paw edoema method, the alloxan-induced diabetes in wistar rats method, and the FRAP (ferric reducing antioxidant power) method, respectively, the derivatives were examined for their in vivo anti-diabetic, in vivo anti-inflammatory, and in vitro free radical scavenging activities. Some of the compounds showed promise as powerful anti-inflammatory, anti-free radical, and anti-diabetic medications. The most effective anti-diabetic compounds, NB7, NB12, and NB13, were docked using MOE software to study some potential structural insights into the potential binding patterns with the target PPAR active sites (PDB ID: 2PRG). The dichloro derivative chemical NB-7 has demonstrated strong anti-inflammatory and antioxidant potential in the current investigation in addition to having the highest anti-diabetic efficacy

    Background. Derivatives of thiophene and sulphonamide showed various pharmacological activities including antimicrobial and dihydrofolate reductase (DHFR) inhibition activity. Dihydrofolate reductase and dihydropteroate synthetase enzymes are responsible for bacterial growth and cell proliferation of cancer cells. Method: In the first step, thiophene was synthesized from cyclohexanone, sulphur and ethyl cyanoacetate by Gewald reaction. Second step involved cyclization of ethyl 2-aminothiophene-3-carboxylate conducted using formamide. In the third step, the carbonyl group was replaced by chlorine in the presence of POCl3. Then the chlorine group was removed by substituted sulphonamide. A series of derivatives were synthesized and evaluated for antimicrobial, anti-oxidant and DHFR inhibition activity. Newly synthesized derivatives of sulphonamide clubbed thiophene showed moderate to excellent antimicrobial and DHFR inhibition activity. Results. A series of thiophene clubbed sulphonamide conjugates were designed, synthesized and their structures were characterized using 1H NMR, 13C NMR, IR and HR-MS spectral analysis. The antioxidant activity was performed by DPPH and hydrogen peroxide method. Among these derivatives, the compounds a and b showed comparable anti-oxidant activity 76.29% and 73.25% respectively against DPPH as compared to standard drug ascorbic acid (82.68%). Remaining conjugates displayed significant anti-oxidant activity. The docking study was performed using Molegro virtual docker (MVD) molecular docking suggested a remarkable binding pose for all the thiophene linked sulphonamide derivatives. Conclusion. Compounds with electron donating groups showed potential activity. The binding affinity of these derivatives against dihydropteroate synthetase (DHTS) and dihydrofolate reductase (DHFR) enzymes were confirmed by molecular docking studies. The ADME and toxicity profile was studied. The compounds can serve as potential DHFR and DHTS inhibitors

    Recurrent acute pancreatitis due to a santorinicele in a young patient

    Get PDF
    A cystic dilatation of the terminal portion of the minor pancreatic duct (duct of Santorini) is referred to as a santorinicele. It is usually associated with pancreas divisum and has been suggested to be a cause of relative stenosis of the minor papilla, often leading to recurrent pancreatitis. While this anomaly has been reported in the paediatric population, it is more commonly found in the elderly. We present a 27-year-old woman with recurrent acute pancreatitis attributed to a santorinicele with a dorsal duct-exclusive pancreatic drainage
