Control robusto del pH en un fotobiorreactor raceway

Revista Iberoamericana de Automática e Informática Industrial RIAI, 2022
Este  trabajo  presenta  una  primera  aproximación al control robusto del pH en un fotobiorreactor raceway  para  el  cultivo  de  microalgas. En este tipo de procesos el pH es la variable más crítica a controlar teniendo una relación directa con la ...

Running coupling and non-perturbative corrections for O(N) free energy and for disk capacitor

Journal of High Energy Physics, 2022
We reconsider the complete solution of the linear TBA equation describing the energy density of finite density states in the O(N) nonlinear sigma models by the Wiener-Hopf method.

Analytic resurgence in the O(4) model

Journal of High Energy Physics, 2022
We study the perturbative expansion of the ground state energy in the presence of an external field coupled to a conserved charge in the integrable two-dimensional O(4) nonlinear sigma model.

A quantum multiplier based on the quantum Fourier transform algorithm

Dianzi Jishu Yingyong, 2022
Multiplier is one of the basic units in many quantum algorithms. In order to implement the multiplying operations and use as few auxiliary qubits in the quantum circuit as possible, a quantum multiplier based on the quantum Fourier transform is proposed.

Retrospective Performance Analyses of over Two Million U.S. QuantiFERON Blood Sample Results

Microbiology Spectrum, 2021
Both the QuantiFERON-TB Gold Plus (QFT-Plus) and the QuantiFERON-TB Gold In-Tube (QFT-GIT) tests are interferon gamma (IFN-γ) release assays (IGRAs) intended to detect in vitro cell-mediated immune responses to Mycobacterium tuberculosis antigens.

Comparing QuantiFERON-TB Gold Plus with QuantiFERON-TB Gold in-tube for diagnosis of latent tuberculosis infection among highly TB exposed gold miners in South Africa [version 3; peer review: 2 approved, 1 approved with reservations]

Gates Open Research, 2022
Background: QuantiFERON-TB-Gold-in-tube (QFT-GIT) is an interferon-gamma release assay (IGRA) used to diagnose latent tuberculosis infection. Limited data exists on performance of QuantiFERON-TB Gold-Plus (QFT-Plus), a next generation of IGRA that ...
