    • Neutral to charged kaon yield fluctuations in Pb – Pb collisions at √sNN = 2.76 TeV 

      Acharya, Shreyasi; Gay Ducati, Maria Beatriz; Pereira, Luis Gustavo; Pezzi, Rafael Peretti; ALICE Collaboration (2022) [Artigo de periódico]
      We present the first measurement of event-by-event fluctuations in the kaon sector in Pb – Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used to evaluate the ...

    • Nonlinear dynamics in isotropic and anisotropic nagneto-optical traps 

      Haas, Fernando; Soares, Luiz Gustavo Ferreira (2022) [Artigo de periódico]
      We briefly review some recent advances in the field of nonlinear dynamics of atomic clouds in magneto-optical traps. A hydrodynamical model in a three-dimensional geometry is applied and analyzed using a variational approach. ...

    • Gold nanoparticles inhibit steroid-insensitive asthma in mice preserving histone deacetylase 2 and NRF2 pathways 

      Serra, Magda Fraguas; Santana, Amanda da Costa Cotias; Pimentel, Andreza da Silva; Arantes, Ana Carolina Santos de; Pires, Ana Lucia de Aguiar; Deus, Manuella Lanzetti Daher de; Hickmann, Jandir Miguel; Barreto, Emiliano de Oliveira; Carvalho, Vinicius de Frias; Martins, Patricia Machado Rodrigues e Silva; Cordeiro, Renato Sergio Balao; Martins, Marco Aurélio (2022) [Artigo de periódico]
      Background: Gold nanoparticles (AuNPs) can inhibit pivotal pathological changes in experimental asthma, but their effect on steroid-insensitive asthma is unclear. The current study assessed the effectiveness of nebulized ...

    • Nuclear modification factor in small system collisions within perturbative QCD including thermal effects 

      Moriggi, Lucas Soster; Machado, Magno Valério Trindade (2022) [Artigo de periódico]
      In this paper, the nuclear modification factors, RxA, are investigated for pion production in small system collisions, measured by PHENIX experiment at RHIC (Relativistic Heavy Ion Collider). The theoretical framework is ...

    • MaNGA 8313-1901 : gas accretion observed in a blue compact dwarf galaxy 

      Ju, Mengting; Yin, Jun; Liu, Rongrong; Hao, Lei; Shao, Zhengyi; Feng, Shuai; Riffel, Rogério; Liu, Chenxu; Stark, David V.; Shen, Shiyin; Telles, Jose Eduardo; Fernández-Trincado, José Gregorio; Wang, Junfeng; Xu, Haiguang; Bizyaev, D.; Rong, Yu (2022) [Artigo de periódico]
      Gas accretion is an important process in the evolution of galaxies, but it has limited direct observational evidences. In this paper, we report the detection of a possible ongoing gas accretion event in a blue compact dwarf ...

    • Developing a victorious strategy to the second strong gravitational lensing data challenge 

      De Bom, Clécio Roque; Fraga, Bernardo Machado de Oliveira; Dias, Luciana Olivia; Schubert, Patrick; Valentin, Manuel Blanco; Furlanetto, Cristina; Makler, Martín; Teles, K.; Albuquerque, M.P.; Metcalf, Robert Benton (2022) [Artigo de periódico]
      Strong lensing is a powerful probe of the matter distribution in galaxies and clusters and a relevant tool for cosmography. Analyses of strong gravitational lenses with deep learning have become a popular approach due to ...

    • Group velocity of obliquely propagating Alfvén waves in a magnetized dusty plasma 

      De Toni, Luan Bottin; Gaelzer, Rudi; Ziebell, Luiz Fernando (2022) [Artigo de periódico]
      In this work, we investigate the characteristics of the group velocity of obliquely propagating Alfvén in a dusty plasma typical of a stellar wind. The dispersion relation is derived with the aid of the kinetic theory for ...

    • Identification of hadronic tau lepton decays using a deep neural network 

      Tumasyan, Armen; Silveira, Gustavo Gil da; Bernardes, César Augusto; CMS Collaboration (2022) [Artigo de periódico]
      A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (τh) that originate from genuine tau leptons in the CMS detector against τh candidates that originate from quark or gluon jets, ...

    • Ionic liquid based dopant-free band edge shift in BiVO4 particles for photocatalysis under simulated sunlight irradiation 

      Khan, Niqab; Wolff, Rogério Nunes; Ullah, Hameed; Chacón, Gustavo; Rosa, Washington Santa; Dupont, Jairton; Gonçalves, Renato Vitalino; Khan, Sherdil (2022) [Artigo de periódico]
      Foreign elemental doping is a widely utilized strategy to modify the electronic structure of semiconductors. Herein, we present a dopant-free novel synthesis approach to control the electronic structure of a semiconductor. ...

    • Abundance analysis of APOGEE spectra for 58 metal-poor stars from the bulge spheroid 

      Razera, Roberta Ferreira; Santiago, Basilio Xavier; Zoccali, Manuela (2022) [Artigo de periódico]
      The central part of the Galaxy hosts a multitude of stellar populations, including the spheroidal bulge stars, stars moved to the bulge through secular evolution of the bar, inner halo, inner thick disc, inner thin disc, ...
