We modified a modern herbal MRI contrast agent for biological applications. This modification was realized by omitting salinity and free ions of the contrast media. As a result, both the toxicity and the relaxivity of the product improved. We also chemically analyzed the modified agent and confirmed the elimination of some annoying free ions and molecules.

In this paper we deal with sampled-data implementation of Lipschitz on bounded sets global asymptotic stabilizers for retarded nonlinear systems, described by Lipschitz on bounded sets functions. We show, with no particular assumption nor requiring exhibition of any Lyapunov–Krasovskii functional, that fast sampling always ensures stabilization in the sample-and-hold sense. That is, for any ball of the origin of initial states and for any final target ball of the origin, there exists a suitably small sampling period such that all solutions starting in the former ball are driven into the latter one, with uniform overshoot and uniform settling time. Global asymptotic and locally exponentially stabilizers are also investigated, showing in this case semi-global uniform convergence to the origin under fast sampling.

Cloud computing enables remote execution of users’ tasks. The pervasive adoption of cloud computing in smart cities’ services and applications requires timely execution of tasks adhering to Quality of Services (QoS). However, the increasing use of computing servers exacerbates the issues of high energy consumption, operating costs, and environmental pollution. Maximizing the performance and minimizing the energy in the cloud data center is challenging. In this paper, we propose a performance and energy optimization bi-objective algorithm to trade off the contradicting performance and energy objectives. An evolutionary algorithm-based multi-objective optimization is for the first time proposed using system performance counters. The performance of the proposed model is evaluated using a realistic cloud dataset in a cloud computing environment. Our experimental results achieve higher performance and lower energy consumption compared to a state-of-the-art algorithm.
Renewable energy is gaining wide attention to address the issues, such as depleting resources and environmental degradation, linked with the current non-renewable energy. However, storing renewable energy is challengi...
