This paper presents a study on the VHDL implementation of a class of binary irregular structured LDPC codes (IS-LDPC) applied to 100 Gbps optical networks. A comparison between two iterative decoding algorithms for irregular structured LDPC codes, sum-product based on loglikelihood ratio and min-sum, is used to define the best choice for implementation. The performances of IS-LDPC codes are eva...

When performing maximum-likelihood quantum-state tomography, one must find the quantum state that maximizes the likelihood of the state given observed measurements on identically prepared systems. The optimization is usually performed with iterative algorithms. This paper provides a gradient-based upper bound on the ratio of the true maximum likelihood and the likelihood of the state of the cur...

We consider the problem of scoring Bayesian Network Classifiers (BNCs) on the basis of the conditional loglikelihood (CLL). Currently, optimization is usually performed in BN parameter space, but for perfect graphs (such as Naive Bayes, TANs and FANs) a mapping to an equivalent Logistic Regression (LR) model is possible, and optimization can be performed in LR parameter space. We perform an emp...

This paper briefly describes the systems presented by the Software Technologies Working Group (http://gtts.ehu.es, GTTS) of the University of the Basque Country (UPV/EHU) to the Spoken Web Search (SWS) task at MediaEval 2013. GTTS systems consist of four main modules: (1) feature extraction; (2) speech activity detection; (3) DTW-based query matching; and (4) score calibration and fusion. The m...

cytomegalovirus (cmv) infection can cause colitis which is usually manifested with fever, weight loss, anorexia and abdominal pain.watery diarrhea can be the only manifestation. cmv colitis usually can not be diagnosed according to the clinical findings. moreover, endoscopic appearance can exactly mimic pseudo-membranous colitis. here by, we are presenting a patient with fever and watery diarrh...

objective(s):this study aims at exploring cytotoxic activity of different peptides derived from vsvg protein against mcf-7 and mda-mb-231 breast cancer cell lines and human embryonic kidney normal cell (hek 293).    materials and methods: the anticp web server was used to predict anticancer peptides. the cytotoxic activity of peptides with high score (p26, p7) and low score (p19) was examined b...

in this paper, we propose a new definition of intuitionistic fuzzyquasi-metric and pseudo-metric spaces based on intuitionistic fuzzy points. weprove some properties of intuitionistic fuzzy quasi- metric and pseudo-metricspaces, and show that every intuitionistic fuzzy pseudo-metric space is intuitionisticfuzzy regular and intuitionistic fuzzy completely normal and henceintuitionistic fuzzy nor...
