X-ray diffraction data on a few retroviral integrases show a flexible loop near the active site. By sequence alignment, the peptide region 207-218 of Mo-MLV IN appears to correspond to this flexible loop. In this study, ...

Context: This work starts from the hypothesis that controllers for adaptive systems that are partitioned into elements, in this work called microcontrollers, which are dedicated to each service involved in the stages of a ...

Human indoleamine 2,3-dioxygenase catalyzes the oxidative cleavage of tryptophan to N-formyl kynurenine, the initial and rate-limiting step in the kynurenine pathway. Additionally, this enzyme has been identified as a ...

This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...

This article presents a new mathematical model to solve the restoration problem in balanced distribution systems with distributed generators (DGs) considering closed-loop topology operation during the restorative state. ...

One pair of reactants, Cu(hfac)(2) = M and the hinge-flexible radical ligand 5-(3-N-tert-butyl-N-aminoxylphenyl)pyrimidine (3PPN = L), yields a diverse set of five coordination complexes: a cyclic loop M(2)L(1) dimer; a ...

Recently, a Model Predictive Control (MPC) suitable for closed-loop re-identification was proposed, which solves the potential conflict between the persistent excitation of the system and the stabilization of the closed-loop ...

The physical limitations of silicon forced the industry to develop solutions that exploit the processing power of combining several general purpose processors. Even complex supercomputers that have multiple processors, ...

The Phase-Locked Loops, conceived in the 1930’s by Henri de Bellescize, and used in a large scale on TV sets and integrated services digital telecommunication networks are nowadays increasing their relevance, being present ...
