Integral hydrophobic treatment is the most effective method to prolong the service life of the concrete by resisting the transport of water containing aggressive ions.The hydrophobicity phenomenon of cementitious materials with carboxylic acid type admixture has been presented, and experimental studies, including water adsorption, amount of hydrati
In this paper, we present a new algorithm for fast correlation attacks on stream ciphers with improved cryptanalysis results on the Sosemanuk stream cipher, one of the 7 finalists in the eSTREAM project in 2008.The new algorithm exploits the direct sum construction of covering codes in decoding phase which approximates the random vectors to a neare
We report direct observational evidence for a latitudinal dependence of dust cloud opacity in ultracool dwarfs, indicating that equatorial latitudes are cloudier than polar latitudes.These results are based on a strong positive correlation between the viewing geometry and the mid-infrared silicate absorption strength in mid-L dwarfs using mid-infra
Introduction: The burden of acute febrile illness remains underestimated in many low- and middle-income countries.The rationale of this study revolves around the gaps in diagnostics for acute febrile illnesses in these regions.Aim: To highlight the seroprevalence and co-infections of different infectious aetiologies in blood culture negative febril
There is a strong and continuously growing interest in using large electronic healthcare databases to study health outcomes and the effects of pharmaceutical products.However, concerns regarding disease misclassification (i.e.classification errors of the disease status) and its impact on the study results are legitimate.Validation is therefore incr
