A simple and precise methodology to determine particulate matter mass in atmospheric filters; validation and application cases
Barba Lobo, Alejandro; Gutiérrez Álvarez, Isidoro; Adame Carnero, José Antonio
; Bolívar Raya, Juan Pedro (Elsevier, 2022-11-01)
In the past decades, particulate matter (PM) measurements have been used extensively in atmospheric sciences, as it allows studying the evolution of tracers for different atmospheric processes and the effects of atmospheric ... -
Structural study of water/alcohol mixtures adsorbed in MFI and MEL porosils
(Elsevier, 2022-10)Ethanol and other biofuels produced during biomass conversion must be separated from the fermentation broth (mainly water) before being used as a fuel. This can be addressed by adsorption-based separation using porous ... -
Digital quantum simulation of an extended Agassi model: Using machine learning to disentangle its phase-diagram
Sáiz, Álvaro; García Ramos, José Enrique; Arias Carrasco, José Miguel; Lamata, Lucas; Pérez Fernández, Pedro (American Physical Society, 2022)
A digital quantum simulation for the extended Agassi model is proposed using a quantum platform with eight trapped ions. The extended Agassi model is an analytically solvable model including both short range pairing and ... -
Solubility of Methane in Water: Some Useful Results for Hydrate Nucleation
Grabowska, Joanna; Blázquez, Samuel; Sanz, Eduardo; Zerón, Iván M.; Algaba Fernández, Jesús; Míguez, José Manuel; Jiménez Blas, Felipe; Vega, Carlos (American Chemical Society, 2022)
In this paper, the solubility of methane in water along the 400 bar isobar is determined by computer simulations using the TIP4P/Ice force field for water and a simple LJ model for methane. In particular, the solubility ... -
Accessing pion GPDs through the Sullivan process: is it feasible?
Morgado Chávez, José Manuel; Bertone, Valerio; Defurne, Maxime; Soto, Feliciano de; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José; Segovia, Jorge (Sociedad Mexicana de Física, 2022)
Describing hadronic structure is one of the most intriguing problems in physics. In this respect, generalized parton distributions (GPDs) constitute an outstanding tool, allowing to draw “three dimensional pictures” of ... -
A practical and general methodology for efficiency calibration of coaxial Ge detectors
Barba Lobo, Alejandro; Bolívar Raya, Juan Pedro (Elsevier, 2022-05-06)
The correct determination of artificial and natural radionuclides like 152Eu, 137,134Cs, 60,57Co, etc., and 234,228Th, 228,226Ra, 210Pb and 40K, respectively, is essential for many environmental science fields. For this, ... -
Concerning pion parton distributions
Cui, Zhu-Fang; Ding, M.; Morgado Chávez, José Manuel; Raya, Khépani; Binosi, Daniele; Chang, L.; Papavassiliou, J.; Roberts, Craig D.; Rodríguez Quintero, José; Schmidt, S. M. (Springer, 2022-01)
Analyses of the pion valence-quark distribution function (DF), uπ (x; ζ ), which explicitly incorporate the behaviour of the pion wave function prescribed by quantum chromodynamics (QCD), predict uπ (x 1; ζ ) ∼ (1 − ... -
Use of a fuzzy qualitative model to reanalyze radon relationship with atmospheric variables in a coastal area near a NORM repository
Gutiérrez Álvarez, Isidoro; Aroba Páez, Javier; Martín Domínguez, José Enrique; Adame Carnero, José Antonio; Bolívar Raya, Juan Pedro (Elsevier, 2022-11)
A soft computing methodology, PreFuRGe (Predictive Fuzzy Rules Generator), was applied to study atmospheric radon in relation to other meteorological variables. This algorithm is based on fuzzy clustering and generates a ... -

Campanha, Danilo R.; Mendoza, Edgar; Silva, Mateus X.; Velloso, Paulo F. G.; Carvajal Zaera, Miguel; Wakelam, Valentine; Galvao, Breno R. L. (Royal Astronomical Society, 2022-06-15)

IM Normae: The Death Spiral of a Cataclysmic Variable?
Patterson, Joseph; Miguel Agustino, Enrique de; Knigge, Christian (American Astronomical Society, 2022-01)
We present a study of the orbital light curves of the recurrent nova IM Normae since its 2002 outburst. The broad “eclipses” recur with a 2.46 hr period, which increases on a timescale of 1.28(16) × 106 yr. Under the ... -
Exceptional spectral phase in a dissipative collective spin model
Rubio-García, Álvaro; Relaño Pérez, Armando; Corps, Ángel L.; Molina, Rafael A.; Pérez Bernal, Francisco; García Ramos, José Enrique; Dukelsky, J. (American Physical Society, 2022)
We study a model of a quantum collective spin weakly coupled to a spin-polarized Markovian environment and find that the spectrum is divided into two regions that we name normal and exceptional Liouvillian spectral phases. ... -
Density functional theory for the prediction of interfacial properties of molecular fluids within the SAFT-g coarse-grained approach
Algaba Fernández, Jesús; Mendiboure, Bruno; Gómez Álvarez, Paula; Jiménez Blas, Felipe (Royal Society of Chemistry, 2022)
Recently, we have proposed the SAFT-VR Mie MF DFT approach [Algaba et al., Phys. Chem. Chem. Phys., 2019, 21, 11937–11948] to investigate systems that exhibit fluid–fluid interfaces. This formalism is based on the combination ... -

Morgado Chávez, José Manuel; Bertone, Valerio; Soto Borrero, Feliciano Carlos de; Defurne, Maxime; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José; Segovia, Jorge (American Physical Society, 2022-05)
We present the first systematic feasibility study of accessing generalized parton distributions of the pion at an electron-ion collider through deeply virtual Compton scattering. Relying on state-of-the-art models for ... -
Emergence of pion parton distributions
Cui, Zhu-Fang; Ding, M.; Morgado Chávez, José Manuel; Raya, Khépani; Binosi, Daniele; Chang, L.; Soto, F. de; Roberts, Craig D.; Rodríguez Quintero, José; Schmidt, S. M. (American Physical Society, 2022-05)
Supposing only that there is an effective charge which defines an evolution scheme for parton distribution functions (DFs) that is all-orders exact, strict lower and upper bounds on all Mellin moments of the valence-quark ... -

Morgado Chávez, José Manuel; Bertone, Valerio; Soto Borrero, Feliciano Carlos de; Defurne, Maxime; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José; Segovia, Jorge (American Physical Society, 2022-05)
We introduce a new family of generalized parton distribution models able to fulfill by construction all the theoretical properties imposed by QCD. These models are built on standard parton distribution functions and ... -
Reconstructing QCD spectral functions with Gaussian processes
Horak, Jan; Pawlowski, Jan M.; Rodríguez Quintero, José; Turnwald, Jonas; Urban, Julián M.; Wink, Nicolas; Zafeiropoulos, S. (American Physical Society, 2022-02)
We reconstruct ghost and gluon spectral functions in 2 þ 1 flavor QCD with Gaussian process regression. This framework allows us to largely suppress spurious oscillations and other common reconstruction artifacts by ... -
Proton lifetime in minimal SUSY SU(5) in light of LHC results
(Springer, 2022-02)We examine proton decay mediated by color-triplet Higgsinos in minimal supersymmetric SU(5) grand unified theory in light of the discovery of the Higgs boson and the absence of SUSY signals at the LHC. We pay special ... -

The 28 GeV dimuon excess in lepton specific THDM
(Elsevier, 2022-03)We explore the Higgs mass spectrum in a class of Two Higgs Doublet Models (THDMs) in which a scalar SU(2)Ldoublet interacts only with quarks, while the second one interacts only with leptons. The spectrum includes two ... -
