Nephrin is a key functional component of the slit diaphragm, structurally unresolved molecular filter in renal glomerular capillaries. Abnormal nephrin or its absence results severe proteinuria and loss diaphragm. The diaphragm thin extracellular membrane spanning approximately 40-nm-wide filtration between podocyte foot processes covering capillary surface. Using electron tomography, we show that comprises network winding strands with pores same size as smaller than albumin molecules,...
This paper contributes to a critical methodological discussion that has direct ramifications for policy studies: how computational methods can be concretely incorporated into existing processes of textual analysis and interpretation without compromising scientific integrity. We focus on the method topic modeling investigate it interacts with two larger families qualitative methods: content classification characterized by interest in words as communication units discourse representation...
This article presents the vision and results of creating basis for a national semantic Web content infrastructure in Finland 2003-2007. The main elements are shared open metadata schemas, core ontologies, public ontology services. Several practical applications testing demonstrating usefulness overviewed fields eculture, ehealth, egovernment, elearning, ecommerce.
This paper presents the CultureSampo system from viewpoint of publishing heterogeneous linked data as a service. Discussed are problems converting legacy into data, well challenge making massively
Digital collections of the National Library Finland (NLF) contain over 10 million pages historical newspapers, journals and some technical ephemera. The material ranges from early Finnish newspapers 1771 until present day. up to 1910 can be viewed in public web service, where as anything later is available at six legal deposit libraries Finland. A recent user study noticed that a different type researcher use one key uses collection. has gotten several requests provide content digital...
LAS is a command-line tool for lemmatizing, morphological analysis, inflected form generation, hyphenation and language identification of multiple languages.These functionalities are use as part many workflows requiring natural processing.Indeed, has been used example pipeline entity recognition (Mäkelä 2014), in creating contextual reader texts English, Finnish Latin (Mäkelä, Lindquist, Hyvönen 2016), processing historical newspaper collection preparation data publication (Pääkkönen et al. 2016).
Research in the digital humanities and computational social sciences requires overcoming complexity research data, methodology, questions. In this article, we show through case studies of three different science projects, that these problems are prevalent, multiform, as well laborious to counter. Yet, without facilities for acknowledging, detecting, handling correcting such bias, any results based on material will be faulty. Therefore, argue need a wider recognition acknowledgement...
In this article, we introduce a linguistic approach to studying affectivity as fundamental feature of news journalism. By reconceptualising beyond emotive storytelling, intentional stance-taking or evaluative expression, propose methodology that highlights how conventions related mediating, modulating and managing permeate journalistic genres. Drawing from conversation analysis, Bakhtinian theory language dialogical notion affective meaning-making, investigate selected forms structures –...
