A combined transcriptomic and genomic analysis identifies a gene signature associated with the response to anti-TNF therapy in rheumatoid arthritis
(Frontiers, 2019-07-02)[Abstract] Background: Rheumatoid arthritis (RA) is the most frequent autoimmune disease involving the joints. Although anti-TNF therapies have proven effective in the management of RA, approximately one third of patients ... -
A common solution for tokenization and part-of-speech tagging: one-pass Viterbi algorithm vs. Iterative approaches
(Springer-Verlag, 2002)Current taggers assume that input texts are already tokenized, i.e. correctly segmented in \emph{tokens} or high level information units that identify each individual component of the texts. This working hypothesis is ... -
A comparative linguistic analysis of english and spanish advertising discourse
(2015)[Resumo] O obxectivo desta tese é probar cientificamente que o discurso publicitario en lingua inglesa é máis variado, rico, con maior flexibilidade e máis efectivo que o discurso publicitario en lingua española, e isto ... -
A Comparative Study of Doppler Ultrasound Against Temporal Artery Biopsy in the Diagnosis of Giant Cell Arteritis
(Elsevier, 2020-08-13)[Abstract] Background. Giant cell arteritis (GCA) is a vasculitis that affects medium- and large-sized arteries. Temporal artery biopsy is the gold standard for diagnosis. In view of the high demand for temporal biopsies, ... -
A Comparative Study of Low Cost Open Source EEG Devices
(MDPI AG, 2019-08-05)[Abstract] A comparison of two open source electroencephalography devices designed to acquire signals associated to the brain activity is presented in this work. The experiments are developed considering the task of ... -
A Comparative Study of Participation in Physical Education Classes among 170,347 Adolescents from 54 Low-, Middle-, and High-Income Countries
(MDPI AG, 2020-08-02)[Abstract] Given the need for comparative research on the participation of adolescents in physical education (PE) classes as a privileged space for physical activity (PA) promotion, this study sought to estimate, analyse ... -
A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters
(MDPI, 2011-08)After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ... -
A comparative study of STBC transmissions at 2.4 GHz over indoor channels using a 2 × 2 MIMO testbed
(Hindawi, 2008)[Abstract]: In this paper we employ a 2 × 2 Multiple-Input Multiple-Output (MIMO) hardware platform to evaluate, in realistic indoor scenarios, the performance of different space-time block coded (STBC) transmissions at ... -
A comparative study on user gestural inputs for navigation in NUI‑based 3D virtual environments
(Springer, 2021)[Abstract] This paper describes the results of a case study intended to compare three different user movement paradigms (metaphoric, symbolic and natural) designed to control the visit of virtual environments for a NUI-based ... -
A comparison of missing value imputation methods applied to daily precipitation in a semi-arid and a humid region of Mexico
(Universidad Nacional Autónoma de México, 2023)[Abstract:] Climatological data with unreliable or missing values is an important area of research, and multiple methods are available to fill in missing data and evaluate data quality. Our study aims to compare the ... -
A Comparison of Optimization Techniques for Power Patterns with Low Sidelobes Generated by Linear Arrays with Efficient Excitation Distributions
(John Wiley & Sons, Inc., 2005-04-05)[Abstract] Equispaced linear arrays that have uniformly excited central elements and monotonically decreasing flanking segments have been shown to yield low-sidelobe patterns with specified constraints on the effective ... -
A comparison of para, meta, and ortho-carborane centred non-fullerene acceptors for organic solar cells
(Royal Society of Chemistry, 2023-03-28)[Abstract]: We report the first examples of carborane-containing non-fullerene acceptors (NFAs), and their use in organic photovoltaic (OPV) devices. NFAs employing an A–D–A′–D–A type design centred around a central electron ... -
A comparison of performance of K-complex classification methods using feature selection
(2016-01-20)[Abstract] The main objective of this work is to obtain a method that achieves the best accuracy results with a low false positive rate in the classification of K-complexes, a kind of transient waveform found in the ... -
A comparison of statistical association measures for identifying dependency-based collocations in various languages
(Association for Computational Linguistics (ACL), 2019)[Abstract] This paper presents an exploration of different statistical association measures to automatically identify collocations from corpora in English, Portuguese, and Spanish. To evaluate the impact of the association ... -
A Comparison of the Relative Sensitivity of Structural and Functional Cellular Responses in the Alga Chlamydomonas eugametos Exposed to the Herbicide Paraquat
(Springer, 1999-04)The effect of the herbicide paraquat on the freshwater microalga Chlamydomonas eugametos was studied in function of different parameters such as growth, elemental composition, total lipids, and photosynthetic pigments ... -
A complement to autotuning methods on PID controllers
(International Federation of Automatic Control, 2000)[Abstract] This paper describes a complement to the autotuning ATV method. The proposed strategy is based in a frequency response design technique to get a three-term controller as a special case of a lead-lag design. The ... -
A complexity approach for identifying aesthetic composite landscapes
(Springer, 2014)[Abstract] The present paper describes a series of features related to complexity which may allow to estimate the complexity of an image as a whole, of all the elements integrating it and of those which are its focus of ... -
