Operations Management at the service of health care management: Example of a proposal for action research to plan and schedule health resources in scenarios derived from the COVID-19 outbreak

[EN] With this work, we intend to promote research on the application of Operations Management tools in order to assist with decision-making in health crisis situations. During the first six weeks of the COVID-19 crisis in Spain, we have contacted a large number of hospital and health department managers in the Valencian Community and other regions of Spain. The result is that very few, at least when contact was made and at the time of writing this article, had consulted staff members in the Operations Management area for advice on this situation, and they are quite reluctant to do so. This is in spite of the fact that some medical sources also consider this crisis to be one of resources, not merely a medical crisis. Our opinion is that Operations Management can make a useful and valuable contribution to anticipate and improve the management of scarce resources, even in times of crisis. If those responsible for public health or heads of hospitals do not see this usefulness, then there is a huge gap between research and practice in Operations Management and what is transmitted to the healthcare sector. Our aim is to help reduce this gap.Marin-Garcia, JA.; García Sabater, JP.; Ruiz, A.; Maheut, J.; García Sabater, JJ. (2020).

Observation of charmonium pairs produced exclusively in pp collisions

The CP-violating asymmetry a s sl is studied using semileptonic decays of B0 s and B0 s mesons produced in pp collisions at a centre-of-mass energy of 7 TeV at the LHC, exploiting a data sample corresponding to an integrated luminosity of 1.0 fb−1 . The reconstructed final states are D± s µ ∓, with the D± s particle decaying in the φπ± mode. The D± s µ ∓ yields are summed over B0 s and B0 s initial states, and integrated with respect to decay time. Data-driven methods are used to measure efficiency ratios. We obtain a s sl = (−0.06 ± 0.50 ± 0.36)%, where the first uncertainty is statistical and the second systematic

Measurement of the track reconstruction efficiency at LHCb

The determination of track reconstruction efficiencies at LHCb using J/ψ → µ +µ − decays is presented. Efficiencies above 95% are found for the data taking periods in 2010, 2011, and 2012. The ratio of the track reconstruction efficiency of muons in data and simulation is compatible with unity and measured with an uncertainty of 0.8% for data taking in 2010, and at a precision of 0.4% for data taking in 2011 and 2012. For hadrons an additional 1.4% uncertainty due to material interactions is assumed. This result is crucial for accurate cross section and branching fraction measurements in LHCb

Solar photovoltaic technology in isolated rural communities in Latin America and the Caribbean

The main characteristics of photovoltaic (PV) energy and its current development in Latin American and Caribbean countries (LAC); its impact on the electrification of homes, health institutions, and schools in isolated or difficult-to-access communities; and, the advantages thereof are presented and discussed by replacing the use of traditional fuels such as firewood and kerosene in order to improve inhabitants ’health as well as reducing CO2 emissions. Countries like Nicaragua, Peru, Brazil, Argentina, and Chile stand out for their growing PV energy development in the region. A case study of the electrification process by PV systems shows very positive changes are manifested in terms of improving the quality of life of the inhabitants, and especially their physical and mental health state. In addition, CO2 emission reductions from electrifying 216 houses in the nine communities reach an annual amount of 2,164.19 t/yr, reducing firewood consumption by 2,123.39 t/yr and kerosene consumption by 40.80 t/yr However, LAC countries must adopt laws and regulations that regulate the use of PV energy, with an emphasis on recycling systems at the end of their life cycle

Studies of the resonance structure in D0 → KS0 K±π decays

Amplitude models are applied to studies of resonance structure in D 0 → K 0 S K − π + and D 0 → K 0 S K + π − decays using p p collision data corresponding to an integrated luminosity of 3.0     fb − 1 collected by the LHCb experiment. Relative magnitude and phase information is determined, and coherence factors and related observables are computed for both the whole phase space and a restricted region of 100     MeV / c 2 around the K ∗ ( 892 ) ± resonance. Two formulations for the K π   S -wave are used, both of which give a good description of the data. The ratio of branching fractions B ( D 0 → K 0 S K + π − ) / B ( D 0 → K 0 S K − π + ) is measured to be 0.655 ± 0.004 ( stat ) ± 0.006 ( syst ) over the full phase space and 0.370 ± 0.003 ( stat ) ± 0.012 ( syst ) in the restricted region. A search for C P violation is performed using the amplitude models and no significant effect is found. Predictions from SU(3) flavor symmetry for K ∗ ( 892 ) K amplitudes of different charges are compared with the amplitude model results

LHCb detector performance

The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) atCERN. The experiment is designed for precision measurements ofCPviolation and raredecays of beauty and charm hadrons. In this paper the performance of the various LHCbsub-detectors and the trigger system are described, using data taken from 2010 to 2012.It is shown that the design criteria of the experiment have been met. The excellentperformance of the detector has allowed the LHCb collaboration to publish a wide rangeof physics results, demonstrating LHCb's unique role, both as a heavy flavour experimentand as a general purpose detector in the forward region

Search for lepton-flavor violating decays B+ →k+μ±eâ'

A search for the lepton-flavor violating decays B+→K+μ±eâ' is performed using a sample of proton-proton collision data, collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of 3 fb-1. No significant signal is observed, and upper limits on the branching fractions are set as B(B+→K+μ-e+)<7.0(9.5)×10-9 and B(B+→K+μ+e-)<6.4(8.8)×10-9 at 90% (95)% confidence level. The results improve the current best limits on these decays by more than one order of magnitud

Measurement of the ¯B0s Meson Lifetime in D+sπ− Decays

We present a measurement of the ratio of the ¯ B 0 s meson lifetime, in the flavor-specific decay to D + s π − , to that of the ¯ B 0 meson. The p p collision data used correspond to an integrated luminosity of 1     fb − 1 , collected with the LHCb detector, at a center-of-mass energy of 7 TeV. Combining our measured value of 1.010 ± 0.010 ± 0.008 for this ratio with the known ¯ B 0 lifetime, we determine the flavor-specific ¯ B 0 s lifetime to be τ ( ¯ B 0 s ) = 1.535 ± 0.015 ± 0.014     ps , where the uncertainties are statistical and systematic, respectively. This is the most precise measurement to date, and is consistent with previous measurements and theoretical predictions

Measurement of the Z+b-jet cross-section in pp collisions at= 7 TeV in the forward region

: The associated production of a Z boson or an off-shell photon γ ∗ with a bottom quark in the forward region is studied using proton-proton collisions at a centre-of-mass energy of 7 TeV. The Z bosons are reconstructed in the Z/γ∗ → µ +µ − final state from muons with a transverse momentum larger than 20 GeV, while two transverse momentum thresholds are considered for jets (10 GeV and 20 GeV). Both muons and jets are reconstructed in the pseudorapidity range 2.0 10 GeV, and σ(Z/γ∗ (µ +µ −) + b-jet) = 128 ± 36 (stat) ± 22 (syst) ± 5 (lumi) fb (0.2) for pT(jet) > 20 GeV.

ATCG, el futuro de la agricultura

La Sociedad Europea de Ingeniería Agronómica (EurAgEng) concedió, en su congreso de 2004, el Premio UNACOMA de prospección científica a nueve investigadores de la Universidad Politécnica de Madrid. Este premio, patrocinado por la asociación de fabricantes de maquinaria agrícola italiana, promueve la búsqueda de respuestas a dos cuestiones fundamentales: qué puede hacer la ingeniería agronómica por la sociedad y cómo será la agricultura del futuro
