Quantum Probes for the Characterization of Nonlinear Media.

Active optical media leading to interaction Hamiltonians of the form H=λ˜(a+a†)ζ represent a crucial resource for quantum optical technology. In this paper, we address the characterization of those nonlinear media using quantum probes, as opposed to semiclassical ones. In particular, we investigate how squeezed probes may improve and estimation of the nonlinear coupling λ˜ and of the nonlinearity order ζ.

Synthesis of a novel ternary ZIF-8/GO/MgFeO nanocomposite and its application in drug delivery.

In recent year, metal-organic frameworks (MOFs) have been displayed to be a category of promising drug delivery systems because of their crystalline structure, the potential of further functionality, and high porosity. In this research, graphene oxide was synthesized from pure graphite via hummer method and then MgFeO nanoparticles was incorporated into the synthesized ZIF-8 metal-organic frameworks which followed with loading on the surfaces of graphene oxide. In continue, tetracycline as an antibiotic drug was loaded on the surfaces and the cavities of the prepared nanocomposite.

Application of RSM for optimization of glutamic acid production by in bath culture.

Glutamate plays an important role in different cellular processes. Its new applications in various industries have led to an increase in the production of it while fermentation is a very important economically method. In this study, the production of glutamate by the wild type of PTCC(Persian Type Culture Collection) 1532 was optimized using RSM.

On the Quantumness of Multiparameter Estimation Problems for Qubit Systems.

The estimation of more than one parameter in quantum mechanics is a fundamental problem with relevant practical applications. In fact, the ultimate limits in the achievable estimation precision are ultimately linked with the non-commutativity of different observables, a peculiar property of quantum mechanics. We here consider several estimation problems for qubit systems and evaluate the corresponding R, a measure that has been recently introduced in order to quantify how incompatible the parameters to be estimated are.

Synthesis, identification and application of the novel metal-organic framework FeO@PAA@ZIF-8 for the drug delivery of ciprofloxacin and investigation of antibacterial activity.

Today, metal-organic frameworks (MOFs) for the release of drugs have been studied extensively. In this research, we have investigated the novel magnetic framework including FeO@PAA@ZIF-8 for the delivery of ciprofloxacin (CIP) antibiotic. Moreover, the antibacterial activity of FeO@PAA@ZIF-8 and FeO@PAA@ZIF-8@CIP screened against Staphylococcus aureus ( S.
