Risk modeling and analysis of interdependencies of critical infrastructures using colored timed petri nets
(2015)
Petri Nets (PNs) and their variations are a graphical, mathematical language that can be used for the specification, analysis and verification of discrete event systems, including Critical Infrastructures (CIs). Colored ...
Protein secondary structure prediction with bidirectional recurrent neural nets: Can weight updating for each residue enhance performance?
(2010)
Successful protein secondary structure prediction is an important step towards modelling protein 3D structure, with several practical applications. Even though in the last four decades several PSSP algorithms have been ...
Training bidirectional recurrent neural network architectures with the scaled conjugate gradient algorithm
(2016)
Predictions on sequential data, when both the upstream and downstream information is important, is a difficult and challenging task. The Bidirectional Recurrent Neural Network (BRNN) architecture has been designed to deal ...
Enhancing virtual reality systems with smart wearable devices
(Institute of Electrical and Electronics Engineers Inc., 2016)
The proliferation of wearable and smartphone devices with embedded sensors has enabled researchers and engineers to study and understand user behavior at an extremely high fidelity, particularly for use in industries such ...
Video SIMDBench: Benchmarking the Compiler Vectorization for Multimedia Applications
(Institute of Electrical and Electronics Engineers Inc., 2016)
Single Instruction Multiple Data (SIMD) Extensions become popular in computer architectures as a simple and efficient way to exploit the data parallelism hidden in applications. The compiler research community has proposed ...
Enamine-Based Hydrophilic Dynamic Covalent Polymer Networks: Effects of pH, and Copolymer Composition and Concentration on the Aqueous Swelling Degrees and the Gel Formation Times
(2015)
In this work, we explore the formation in water of dynamic covalent polymer networks cross-linked via enamine groups. The polymer networks resulted from the combination of pairs of chemically complementary hydrophilic ...
Synthesis and characterization of reversible and self-healable networks based on acylhydrazone groups
(2014)
A series of seven dynamic covalent networks based on pentaerythritol tetra(benzohydrazide) and 1,10-decanediol dibenzaldehyde were prepared in N,N-dimethylformamide (DMF). The equilibrium degree of swelling in DMF and the ...
HIV-1 subtype distribution and its demographic determinants in newly diagnosed patients in Europe suggest highly compartmentalized epidemics
(2013)
Background: Understanding HIV-1 subtype distribution and epidemiology can assist preventive measures and clinical decisions. Sequence variation may affect antiviral drug resistance development, disease progression, ...
Structural and Redox Properties of Ce1-xZrxO2-δ and Ce0.8Zr0.15RE0.05O2-δ (RE: La, Nd, Pr, Y) Solids Studied by High Temperature in Situ Raman Spectroscopy
(2017)
In situ Raman spectroscopy at temperatures up to 450 °C is used to probe the structural and redox properties of Ce1-xZrxO2-δ solids (x = 0-0.8) prepared by the citrate sol-gel and coprecipitation with urea methods. The ...
A simplified determination of uranium in phosphate rock and phosphogypsum by alpha-spectroscopy after its separation by liquid-extraction
(2012)
A relatively rapid, economic and robust procedure is described for the radiometric analysis of uranium in phosphate rock and phosphogypsum. The analysis is performed by alpha spectroscopy after pre-concentration and ...
