Archiwum Danych Jakościowych przy IFiS PAN
No full textThis text contains information about the Qualitative Data Archive at the Institute of Philosophy and Sociology PAS (QDA) [Archiwum Danych Jakościowych przy IFiS PAN — ADJ; adj.ifispan.pl], which collects and digitalizes databases from a broad range of research in the social sciences and makes them accessible online. The archive was established with the idea of preserving material of a qualitative nature. There were two main aims: to initiate new methods of research using the collected resources and to stimulate theoretical and methodological reflection on the idea of archivization, renewed analysis of data, and various other forms of revisiting research. The creators of the archive have managed to save and digitalize considerable amounts of material derived from studies that are by now historical and are important for Polish sociology and anthropology. The Qualitative Data Archive also contains collections of materials from quite recent studies, which have often been processed in electronic form. For these, the QDA functions as a platform where researchers can present their analyses and findings more widely and in a secure form both for themselves and for their respondents

Overview of the author identification task at PAN 2014
No full textThe author identification task at PAN-2014 focuses on author verification. Similar to PAN-2013 we are given a set of documents by the same author along with exactly one document of questioned authorship, and the task is to determine whether the known and the questioned documents are by the same author or not. In comparison to PAN-2013, a significantly larger corpus was built comprising hundreds of documents in four natural languages (Dutch, English, Greek, and Spanish) and four genres (essays, reviews, novels, opinion articles). In addition, more suitable performance measures are used focusing on the accuracy and the confidence of the predictions as well as the ability of the submitted methods to leave some problems unanswered in case there is great uncertainty. To this end, we adopt the c@1 measure, originally proposed for the question answering task. We received 13 software submissions that were evaluated in the TIRA framework. Analytical evaluation results are presented where one language-independent approach serves as a challenging baseline. Moreover, we continue the successful practice of the PAN labs to examine meta-models based on the combination of all submitted systems. Last but not least, we provide statistical significance tests to demonstrate the important differences between the submitted approaches
Roary : rapid large-scale prokaryote pan genome analysis
No full textThis work was supported by the Wellcome Trust (grant WT 098051).A typical prokaryote population sequencing study can now consist of hundreds or thousands of isolates. Interrogating these datasets can provide detailed insights into the genetic structure of prokaryotic genomes. We introduce Roary, a tool that rapidly builds large-scale pan genomes, identifying the core and accessory genes. Roary makes construction of the pan genome of thousands of prokaryote samples possible on a standard desktop without compromising on the accuracy of results. Using a single CPU Roary can produce a pan genome consisting of 1000 isolates in 4.5 hours using 13 GB of RAM, with further speedups possible using multiple processors.Peer reviewe
Compressive Sensing for PAN-Sharpening
No full textBased on compressive sensing framework and sparse reconstruction technology, a new pan-sharpening method, named Sparse Fusion of Images (SparseFI, pronounced as sparsify), is proposed in [1]. In this paper, the proposed SparseFI algorithm is validated using UltraCam and WorldView-2 data. Visual and statistic analysis show superior performance of SparseFI compared to the existing conventional pan-sharpening methods in general, i.e. rich in spatial information and less spectral distortion. Moreover, popular quality assessment metrics are employed to explore the dependency on regularization parameters and evaluate the efficiency of various sparse reconstruction toolboxes
Synthesis of star and H-shape polymers via a combination of cobalt-mediated radical polymerization and nitrone mediated radical coupling reactions
No full textpeer reviewedVia consecutive cobalt-mediated radical polymerization (CMRP), nitrone-mediated radical coupling (NMRC) and copper catalyzed azide-alkyne cycloaddition (CuAAC), polymers with mikto-arm star and H-shape architecture were synthesized. Poly(vinyl acetate)40-block-poly(acrylonitrile)78-Co(acac)2 polymers were synthesized via CMRC and subsequently coupled using an alkyne functional nitrone. The coupling efficiency of the NMRC process was assessed employing N-tert-butyl a-phenyl nitrone (PBN), which is structurally very similar to the later employed coupling agent. Generally, coupling efficiencies of close to 90% or higher were observed in all cases. Since the coupling reaction yields triblock copolymers bearing an alkoxyamine functionality (and thus also an alkyne group) in the middle of the chain, well defined PEG conjugates could be obtained via CuAAC. Miktoarm star polymers of the structure (PVAc-b-PAN)2-PEG were generated as well as H-shaped material of the structure (PVAc-b-PAN)2-PEG-(PVAc-b-PAN)2 via conjugation with bifunctional PEG. In all cases, very narrow molecular weight material was obtained. Molecular weight analysis of the intermediate and the final products reveals that the hydrodynamic volume of the miktoarm star and the H-shaped materials is not substantially increased during the final conjugation reaction despite the fact that the absolute molecular weight increases by more than a factor of two in the latter case. Success of the conjugation reactions was confirmed via composition analysis via NMR
Pan Asia Networking (PAN) prospectus review 2006-2011
No full textA sample of research findings is provided from Pan Asia Networking (PAN) research projects. These examples give a sense of the type of evidence that has been gathered by partners under PAN’s three main themes (Policies, Technologies, and Effects). The themes are summarized in a table in terms of objectives, research activities, and expected outcomes. PAN-supported research also aims to be relevant and rigorous enough to influence policy debates and attract media attention. PAN encouraged new researchers in ICT4D programming such as the PANdora distance learning research network, and LIRNEasia (communications policy). This review encompasses a wide array of outputs and outcomes
Tweet Author Gender Identification. PAN 2016 Task
No full textThe paper presents an experiment of tweet’s author gender detection. We used PAN 2016 data and task description and have build an application that decides whether an analysed tweet has been written by man or woman. Multiple texts’ characteristics are used as features in the application, such as: references to pictures, to web pages, to other people, emojis, hashtags and a number of words that are associated with tweets written by women and men respectively. For 100 random tweets we obtained average accuracy 0.61. This is good result although it is not as good as the best one in PAN 2016 task
The Great Pan: rebirth of a god in English literature
No full textopenLa tesi si propone di illustrare le caratteristiche e le prerogative del dio Pan nell'antichità, per poi indagare il suo ruolo centrale nella novella 'The story of a Panic' di E. M. Forster e nel romanzo 'The Goat-Foot God' di Dion Fortune, nell'ambito della rinascita novecentesca della figura del dio e del suo culto
PAN-induced podocyte injury model.
No full text(A) Podocytes treated with PAN (25, 50, 75, 100, or 125 μg/ml) for 24 h showed a dose-dependent decrease in viability. (B, C) The protein expression of nephrin, a marker of podocyte injury, was decreased following PAN treatment at concentrations ≥50 μg/ml, demonstrating that a PAN concentration ≥50 μg/ml was sufficient to induce podocyte injury. (D, E) Podocytes were examined by microscopy at 0 and 24 h. After 24 h, podocytes that were treated with 75 μg/ml PAN migrated faster than the controls, suggesting that the motility of PAN-treated podocytes was abnormal. (F) Phalloidin and DAPI staining of untreated control podocytes showed fine F-actin stress fibers, whereas podocytes exposed to 75 μg/ml PAN show a loss of stress fibers and the appearance of a disordered and thick cortical stress fiber distribution.
