Anomaly detection approach to keystroke dynamics based user authentication
2017
Keystroke dynamics is one of the authentication mechanisms which uses natural typing pattern of a user for identification. In this work, we introduced Dependence Clustering based approach to user authentication using keystroke dynamics. In addition, we applied a k-NN-based approach that demonstrated strong results. Most of the existing approaches use only genuine users data for training and validation. We designed a cross validation procedure with artificially generated impostor samples that improves the learning process yet allows fair comparison to previous works. We evaluated the methods using the CMU keystroke dynamics benchmark dataset. Both proposed approaches outperformed the previou…
Aivoverenkiertohäiriön sairastaneiden tasapainoharjoittelun vaikuttavuus RCT-tutkimusten perusteella : evidence on the effectiveness of balance train…
2013
Tausta: Tasapainon ongelmat ovat yleisiä aivoverenkiertöhäiriön (AVH) sairastamisen jälkeen. Vaikka AVH-kuntoutujien kuntoutusmenetelmät ovat kiinnostuksen kohteena, on tasapainoharjoittelun vaikuttavuudesta niukasti näyttöön perustuvaa tietoa. Tarkoitus: Tutkia AVH-kuntoutujien tasapainoharjoittelun vaikuttavuutta tasapainoon tasapaino- ja kävelymuuttujilla RCT-tutkimusten perusteella. Aineisto ja menetelmät: Systemaattinen kirjallisuushaku tehtiin Ovid Medline, CINAHL, Embase, Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials sähköisistä tietokannoista sekä käsihaulla. RCT-tutkimukset, joissa koehenkilöiden ikä oli yli 18- vuotta ja jotka oli julkaistu en…

Psoriasis and Its Impact on In-Hospital Outcome in Patients Hospitalized with Acute Kidney Injury
2020
Background: Psoriasis is a chronic inflammatory disease which affects the body far beyond the skin. Whereas there is solid evidence that chronic skin inflammation in psoriasis drives cardiovascular disease, the impact on renal impairment and acute kidney injury (AKI) is still unclear. We aimed to analyze the impact of psoriasis on the in-hospital outcome of patients hospitalized with AKI. Methods: In this retrospective database study, we investigated data on characteristics, comorbidities, and in-hospital outcomes for all hospitalized patients with AKI stratified for concomitant psoriasis, which were collected by the Federal Office of Statistics in Germany between 2005 and 2016. Results: Am…
Vascular Risk Factors in Mild Cognitive Impairment Subtypes
2007
<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …
Recovery of mobility function and life-space mobility after ischemic stroke: the MOBITEC-Stroke study protocol
2020
Abstract Background Stroke is a major cause of disability and stroke incidence increases with age. Stroke frequently results in permanent limitations of mobility, and, consequently, the need for the help of others in activities of daily living. In order to optimize rehabilitative efforts and their functional outcomes, detailed knowledge of the functional recovery process, regarding mobility, is needed. Objectives of the MOBITEC-Stroke study are: 1.) To characterize mobility, including lower extremity physical function (LEPF) and life space (the geospatial extent of all of a person’s movements), and changes in mobility within the first year after stroke. 2.) To identify and characterize subg…
