11; 95% CI, 1.78-5.43), as did those with hemoglobin <10mg/dL (HR, 4.32; 95% CI, 2.23-8.36). Patients with baseline KPS<90% showed significantly worse DFS (HR, 2.83; 95% CI, 1.60-5.01), as did those with hemoglobin <10mg/dL (HR, 4.16; 95% CI, 2.17-7.95). For stage IIIB cervical cancer, treatment with CRT offers a significant benefit in DFS and OS compared with treatment with RT only. For stage IIIB cervical cancer, treatment with CRT offers a significant benefit in DFS and OS compared with treatment with RT only.Rolling Element Bearings are one of the most ubiquitous machine elements used in various machineries in the manufacturing industry. Prognosis and estimation of residual life of rolling element bearing are very important for efficient implementation of health monitoring and condition-based maintenance. In this paper, a rolling element bearing fault or degradation trend prediction is modeled using Gaussian Process Regression (GPR) method. Various vibration features based on signal complexity, namely Shannon entropy, permutation entropy, and approximate entropy are estimated to obtain the bearing degradation trend. When fault or degradation occurs in rolling element bearing, there is a subtle change in the dynamics of the system and subsequently, there are changes in the features extracted from the vibration signal. In this paper, a comparative analysis of various kernel functions of the GPR model is carried out using accuracy-based metrics. In addition, the combination of goodness of metric (monotonicity (Mon), robustness (Rob), and prognosability (Pro)), namely hybrid metric, is proposed to select the efficient bearing degradation trend of features. Further, the GPR at ARD exponential kernel has been employed to make the prognosis of degradation trend in bearings with a 95% confidence interval (CI). The proposed methodology is validated through a mathematical model of the simulated vibration signal. Finally, from the simulated and experimental data, it is demonstrated that the entropy features have better performance than the statistical features.Uranium (U) mining is an aquatic environmental concern because most of these harmful compounds are discharged into freshwater, reaching the saline environment as the final destination of this contaminated water. Carbonates are present in ocean waters and are essential for benthic organisms, however they may influence the U-induced toxicity. Thus, the aim of this study was to compare the toxicity of uranium nitrate (UN) and uranium acetate (UA) in Artemia salina (AS), which is one of the leading representatives of the marine biota. Alantolactone TGF-beta modulator The cultures of AS (instar II) maintained in artificial seawater containing CaCO3 were exposed for 24 h to different concentrations of U compounds. The results showed that AS were more sensitive to UN (LC50 ≈ 15 μM) when compared with UA (LC50 ≈ 245 μM) indicating higher toxicity of this U compound. Calculated U speciation indicated that Ca2UO2(CO3)3 and (UO2)2CO3(OH)3- complexes predominated under our experimental conditions. The immobilization/lethality was observed after 9 h of exposure for both U compounds. However, only UN caused a significant decrease (≈40%) in the acetylcholinesterase (AChE) activity when compared with control. In order to observe preliminary toxicity effects, we evaluated oxidative stress parameters, such as catalase (CAT) activity, TBARS formation, radical species (RS) generation and cell membrane injury and/or apoptosis (CMI). In this study, we demonstrate that U compounds caused a significant decrease in CAT activity. Similarly, we also observed that UN increased TBARS levels in AS at concentrations 5 times lower than AU (10 μM and 50 μM, respectively). Furthermore, RS generation and CMI were enhanced only on AS treated with UN. Overall, the effects observed here were remarkably significant in AS exposed to UN when compared with AU. In this study, we showed diff
