Text Mining and Gene Expression Analysis Towards Combined Interpretation of High Throughput Data
No full textMicroarrays can capture gene expression activity for thousands of genes simultaneously and thus make it possible to analyze cell physiology and disease processes on molecular level. The interpretation of microarray gene expression experiments profits from knowledge on the analyzed genes and proteins and the biochemical networks in which they play a role. The trend is towards the development of data analysis methods that integrate diverse data types. Currently, the most comprehensive biomedical knowledge source is a large repository of free text articles. Text mining makes it possible to automatically extract and use information from texts.
This thesis addresses two key aspects, biomedical text mining and gene expression data analysis, with the focus on providing high-quality methods and data that contribute to the development of integrated analysis approaches. The work is structured in three parts. Each part begins by providing the relevant background, and each chapter describes the developed methods as well as applications and results.
Part I deals with biomedical text mining:
Chapter 2 summarizes the relevant background of text mining; it describes text mining fundamentals, important text mining tasks, applications and particularities of text mining in the biomedical domain, and evaluation issues.
In Chapter 3, a method for generating high-quality gene and protein name dictionaries is described. The analysis of the generated dictionaries revealed important properties of individual nomenclatures and the used databases (Fundel and Zimmer, 2006). The dictionaries are publicly available via a Wiki, a web service, and several client applications (Szugat et al., 2005).
In Chapter 4, methods for the dictionary-based recognition of gene and protein names in texts and their mapping onto unique database identifiers are described. These methods make it possible to extract information from texts and to integrate text-derived information with data from other sources. Three named entity identification systems have been set up, two of them building upon the previously existing tool ProMiner (Hanisch et al., 2003). All of them have shown very good performance in the BioCreAtIvE challenges (Fundel et al., 2005a; Hanisch et al., 2005; Fundel and Zimmer, 2007).
In Chapter 5, a new method for relation extraction (Fundel et al., 2007) is presented. It was applied on the largest collection of biomedical literature abstracts, and thus a comprehensive network of human gene and protein relations has been generated. A classification approach (Küffner et al., 2006) can be used to specify relation types further; e. g., as activating, direct physical, or gene regulatory relation.
Part II deals with gene expression data analysis:
Gene expression data needs to be processed so that differentially expressed genes can be identified. Gene expression data processing consists of several sequential steps. Two important steps are normalization, which aims at removing systematic variances between measurements, and quantification of differential expression by p-value and fold change determination. Numerous methods exist for these tasks.
Chapter 6 describes the relevant background of gene expression data analysis; it presents the biological and technical principles of microarrays and gives an overview of the most relevant data processing steps. Finally, it provides a short introduction to osteoarthritis, which is in the focus of the analyzed gene expression data sets.
In Chapter 7, quality criteria for the selection of normalization methods are described, and a method for the identification of differentially expressed genes is proposed, which is appropriate for data with large intensity variances between spots representing the same gene (Fundel et al., 2005b). Furthermore, a system is described that selects an appropriate combination of feature selection method and classifier, and thus identifies genes which lead to good classification results and show consistent behavior in different sample subgroups (Davis et al., 2006).
The analysis of several gene expression data sets dealing with osteoarthritis is described in Chapter 8. This chapter contains the biomedical analysis of relevant disease processes and distinct disease stages (Aigner et al., 2006a), and a comparison of various microarray platforms and osteoarthritis models.
Part III deals with integrated approaches and thus provides the connection between parts I and II:
Chapter 9 gives an overview of different types of integrated data analysis approaches, with a focus on approaches that integrate gene expression data with manually compiled data, large-scale networks, or text mining.
In Chapter 10, a method for the identification of genes which are consistently regulated and have a coherent literature background (Küffner et al., 2005) is described. This method indicates how gene and protein name identification and gene expression data can be integrated to return clusters which contain genes that are relevant for the respective experiment together with literature information that supports interpretation.
Finally, in Chapter 11 ideas on how the described methods can contribute to current research and possible future directions are presented

Ei-ladattavan hybridiauton esilämmitys : vaikutukset järjestelmän toimintakykyyn
No full textTämän opinnäytetyön tarkoituksena oli tutkia ja selvittää sähköisen esilämmityksen vaikutuksia hybridijärjestelmän toimintaan. Työssä tarkasteltiin erityisesti vaikutuksia matkaan joka ajettiin pelkästään käyttämällä sähköä auton hybridiakustosta. Samalla seurattiin auton polttoaineen keskikulutuksen muutoksia. Nämä vaikutukset saatiin parhaiten näkyviin, ajamalla samoja reittejä esilämmitetyllä ja ilman esilämmitystä olevalla autolla sekä vertailemalla näistä saatuja tuloksia.
Työssä käytettävä hybridiauto on tekijän omistuksessa ja omassa käytössä. Autoa käytetään pääsääntöisesti taajamaliikenteessä, mutta myös maantie- ja moottoritienopeuksissa. Ajaminen koostuu tekijän normaalista auton käytöstä. Työhön kuuluu kolme eri vaihetta. Ensimmäisessä vaiheessa autoa esilämmitettiin ennen jokaista kotona suoritettua liikkeellelähtöä, työn tekemisen aikana voimassa olleiden suosituksien mukaisesti. Toisessa vaiheessa autoa ei esilämmitetty ennen ajoon lähtöä. Kolmannessa vaiheessa tulokset kirjattiin muistiin ja analysoitiin.
Hybridijärjestelmän käyttö vähentää polttoaineen kulutusta ja päästöjä verrattuna pelkästään polttomoottorilla varustettuun autoon. Auton esilämmitys parantaa sekä ajoturvallisuutta että mukavuutta, kun lämpötila on pakkasella tai lähellä nollaa. Esilämmitetty moottori saavuttaa nopeammin normaalin käyntilämpötilan verrattuna moottoriin, jota ei ole esilämmitetty ennen ajoon lähtöä. Kun moottori käy normaalilla käyntilämpötilallaan, päästöt ja polttoaineen kulutus pienentyvät verrattuna kylmänä käyvään moottoriin. Myös käynnistyksen päästöjä saadaan pienennettyä esilämmityksellä.
Autolla on ajettu pääsääntöisesti lyhyitä matkoja, jolloin järjestelmän polttomoottori ei ole saavuttanut normaalia käyntilämpötilaansa. Työn tuloksena havaittiin, että esilämmitys vaikuttaa myönteisesti hybridijärjestelmän kykyyn käyttää pelkästään sähkömoottoria auton liikuttamiseen. Tämä tulos on ennakko-odotusten mukainen.The purpose of the thesis was to study the effects of electronic preheating on the operation of a hybrid system. The impact of the trip, which was driven by using only electricity from the car hybrid battery, was specifically examined in this thesis. At the same time, changes in the average fuel consumption of the car were tracked. The effects were best noticed driving the same routes with a preheated car and the car without preheating, and comparing the results.
The hybrid car used in the work is owned and used by the author. The car is mainly used in urban area but also at highway speeds. Driving consists of the author´s normal car use. The work involved three different phases. In the first phase, the car was preheated before each start-up at home, in accordance with the recommendations in force at the time of the work. In the second phase, the car was not preheated before start-ups. In the third phase, the results were reported and analyzed.
Using a hybrid system in a car reduces fuel consumption and emissions compared to a car with an internal combustion engine only. Car preheating improves both driving safely and comfort when the temperature is low or near zero degrees. A preheated engine reaches faster its normal operating temperature compared to an engine that has not been preheated before driving. When the engine is running at its normal operating temperature, emissions and fuel consumption are reduced compared to a cold engine. Start-up emissions can also be reduced by preheating.
The car has been mainly driven for short distances, whereupon the internal combustion engine of the system has not reached its normal operating temperature. The study shows that preheating has a positive effect on the ability of the hybrid system to use only an electric motor to move the car. This result is in line with the expectations
Cittadinanza amministrativa e democrazia partecipativa
No full textThis paper examines the definition of participation focusing on the idea of
administrative participation and the concept of administrative democracy.
Therefore, the author analyses the alteration of citizenship notion as the result of the change in
the relationship between citizens and public administration: the adoption of the law 241/1990 –
together with other laws – and the gradual opening of administrative institutions give new tools to
citizens to create an administrative democracy
Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
