Evaluation of the effect of chance correlations on variable selection using Partial Least Squares -Discriminant Analysis
2013
Variable subset selection is often mandatory in high throughput metabolomics and proteomics. However, depending on the variable to sample ratio there is a significant susceptibility of variable selection towards chance correlations. The evaluation of the predictive capabilities of PLSDA models estimated by cross-validation after feature selection provides overly optimistic results if the selection is performed on the entire set and no external validation set is available. In this work, a simulation of the statistical null hypothesis is proposed to test whether the discrimination capability of a PLSDA model after variable selection estimated by cross-validation is statistically higher than t…

A10.8 Evaluation of Disease Activity in Adult Patients with Juvenile Idiopathic Arthritis
2013
Background Juvenile idiopathic arthritis (JIA) is a disease which maintains specific childish rheumatological features during whole life. There is still an open discussion which criteria of the disease activity should be used for the management of adult patients with JIA. Objectives To analyse the usefulness of known disease activity and functional indices used in adult rheumatological practise for the assessment of rheumatoid arthritis (RA) and spondyloarthritidies (SpA): disease acitivity score (DAS), disease acitivity score 28 (DAS28), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Spondylitis Functional Index (BASFI), Health Assessment Questionnaire – disability index…
Thyroid neoplasms: surgical and cyto-histopathological connections on a six year cases study
2018
This study aims to evaluate the percentage of cyto-histologic correlation in patients with a thyroid disease documented through clinical-instrumental, cytological (FNAB), histological and surgical examinations. The purpose of this study is also to determine the percentage of disease incidence and evaluating any surgical indication in relation to biological behavior (benign, malignant or indeterminate lesions, occult carcinomas), sex, and age.Almost all of thyroid neoplasms is manifested through thyroid nodule. Therefore, clinical evidence of the thyroid nodule analysis is primarily related to the need to exclude malignant pathology or carcinoma of the thyroid, present in 4-6.5% of cases.The…
Yksilön yksityisyys esineiden internetin ja asiakasdatan näkökulmasta
2018
Esineiden internetin luoma heterogeeninen ympäristö voi aiheuttaa ihmisille useita erilaisia yksityisyysuhkia, koska tiedonkeruu esineiden internetissä on erittäin laajaa ja passiivista. Tiedonkeruu kohdistuu usein yksilöiden henkilökohtaisiin tietoihin, mikä voi olla vahingollista heidän yksityisyydellensä. Yritykset voivat hyödyntää näitä tietoja useilla liiketoimintansa osa-alueilla. Yritysten näkökulmasta esineiden internet luo uusia tehokkaita mahdollisuuksia kerätä ja hyödyntää asiakasdataa, mikä voi vaikuttaa vahvasti yksityisyysuhkien realisoitumiseen. Tämä kandidaatin tutkielma käsittelee esineiden internetin ja asiakasdatan luomia uhkia yksityisyydelle yksilön näkökulmasta. Tutkie…

Disparità territoriali nella misura del benessere economico. Un’applicazione dell’ESDA ai Sistemi Locali del Lavoro italiani.
2009
In this paper we want to provide a contribution to the analysis of territorial disparities considering Italian Local Labour Systems as basic geographic units. Local Labour Systems (LLS) represent the result of the spatial aggregation of neighbouring municipalities based on the daily commuting flows of local population owing to work reasons. Thus LLS can be described as self-contained economic-territorial spaces, constituted by two or more municipalities, which provide a basis to sub-provincial analysis, being a useful tool for the implementation of local development policies without relations with administrative zones. Having recourse to value added per capita at this particular disaggregat…
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …
I Segni premonitori del Giudizio Universale in un inedito testo tedesco del XV secolo
2022
Numerous lists of the premonitory signs of the Last Judgment and wider narratives focussing on the same motif, which presents variants and articulated typologies, circulated throughout the Middle Ages, both in Latin and in the vernacular languages. Also in Germany the motif continues to be present in literature up to the threshold of the modern age, with the Lutheran Reform which is, also in this case, a watershed. The purpose of the contribution is the philological-literary analysis of a prose composition, in late German, devoted to the 15 Signs of Judgment, still unpublished, preserved in the ms. München, BStB cgm 522 (ff. 163v-166v), datable around 1470. The codex contains a miscellany o…
T2 Mapping of the Sacroiliac Joints in Patients with Axial Spondyloarthritis
2020
Purpose: To test whether T2 mapping of the sacro-iliac joints (SIJs) might help identifying patients with spondyloarthritis. Method: This study included 20 biologic-naive patients with axial spondyloarthritis (10 females; mean age: 38 ± 9years; range, 19–47) and 27 controls (16 males; mean age = 39 ± 13years; range = 28–71) who prospectively underwent SIJs MRI at 1.5 T, including a multislice multiecho spin-echo sequence. Standard MRIs were reviewed to assess the SIJs according to the Assessment of SpondyloArthritis International Society (ASAS) criteria and SPondyloArthritis Research Consortium of Canada (SPARCC) MRI index. T2 maps obtained from multiecho sequences were used to draw regions…
