16 p, 707.4 KB Automated Name Selection for the Network Scale-Up Method / Fenoy, Adrià (Universitat Autònoma de Barcelona. Departament d'Antropologia Social i Cultural) ; Bojanowski, Michał (Kozminski University (Polònia)) ; Lubbers, Miranda J. (Universitat Autònoma de Barcelona. Departament d'Antropologia Social i Cultural)
The distribution of the number of acquaintances among members of a society is a relevant feature of its social structure. Furthermore, the number of acquaintances (or "degree") is used for estimating other societal features, such as the size of hard-to-count subpopulations or social cohesion. [...]

28 p, 211.8 KB Social Network Data Collection : Principles and Modalities / Adams, Jimi (University of Colorado Denver) ; Lubbers, Miranda J. (Universitat Autònoma de Barcelona)
Relational questions require relational data and methods. That may seem like a truism that is unnecessary to make explicit, but the social and behavioral sciences are replete with relational theories (Borgatti and Halgin, 2011) and questions that have repeatedly been examined with data that make essentializing assumptions (Emirbayer, 1997); that is, relying on non-relational data.

25 p, 742.2 KB Stability results for a hierarchical size-structured population model with distributed delay / Hu, Dandan (China University of Geosciences) ; Farkas, József Z. (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Huang, Gang (China University of Geosciences)
In this paper we investigate a structured population model with distributed delay. Our model incorporates two different types of nonlinearities. Specifically we assume that individual growth and mortality are affected by scramble competition, while fertility is affected by contest competition. [...]

144 p, 5.7 MB Onomástica china de la 'Historia de las cosas más notables, ritos y costumbres del gran Reyno de la China', de Juan González de Mendoza / Ramírez Bellerín, Laureano (Universitat Autònoma de Barcelona)
'La Historia de las cosas más notables, ritos y costumbres del gran Reyno de la China', de fray Juan González de Mendoza, tuvo gran difusión en la Europa de la Edad Moderna y marcó, gracias a su popularidad, un punto de inflexión en los incipientes conocimientos que por entonces se tenían del remoto país oriental.

4 p, 382.4 KB Popper's test of quantum mechanics and two-photon "ghost" diffraction / Bramon Planas, Albert (Universitat Autònoma de Barcelona. Departament de Física) ; Escribano, Rafel (Institut de Física d'Altes Energies)
A test on quantum mechanics proposed long ago by Karl Popper is reconsidered with further detail and new insight. An ambiguity in the proposal, which turns out to be essential in order to make the test conclusive, is identified and taken into account for the first time. [...]

32 p, 1.1 MB Radiative corrections to the τ−→(P1P2)−ντ (P1,2=π,K) decays / Escribano, Rafel (Universitat Autònoma de Barcelona. Departament de Física) ; Miranda Hernández, Jesús Alejandro (Institut de Física d'Altes Energies) ; Roig, Pablo (Instituto Politécnico Nacional. Centro de Investigación y de Estudios Avanzados. Departamento de Física)
The radiative corrections to the τ−→(P1P2)−ντ (P1,2=π,K) decays are calculated for the first time. The structure-dependent contributions are obtained using Resonance Chiral Theory. Our results, whose uncertainty is dominated by the model-independent corrections, enable precise tests of CKM unitarity, lepton flavor universality, and non-standard interactions.

18 p, 1.0 MB A combined study of hadronic D+ → K−π+π+ and D+s → K+K+π− decays by means of the analysis of semileptonic D+ → K−π+l+νl decays / Escribano, Rafel (Universitat Autònoma de Barcelona. Departament de Física) ; Masjuan, Pere (Universitat Autònoma de Barcelona. Departament de Física) ; Sánchez-Puertas, Pablo (Institut de Física d'Altes Energies)
We perform a combined study of the two hadronic decays D+→K−π+π+ and D+s→K+K+π− using a detailed analysis of the semileptonic decays D+→K−π+ℓ+νℓ (ℓ=e,μ) thanks to the high-statistics D+→K−π+e+νe dataset provided by the BESIII Collaboration. [...]

10 p, 2.6 MB Ultrafast electronic heat dissipation through surface-to-bulk Coulomb coupling in quantum materials / Principi, Alessandro (University of Manchester. Department of Physics and Astronomy) ; Tielrooij, Klaas-Jan (Institut Català de Nanociència i Nanotecnologia)
The timescale of electronic cooling is an important parameter controlling the performance of devices based on quantum materials for optoelectronic, thermoelectric and thermal management applications. [...]

16 p, 7.9 MB Merging of superfluid Helium nanodroplets with vortices / Escartín Esteban, José María (Institut Català de Nanociència i Nanotecnologia) ; Ancilotto, Francesco (Università di Padova. Dipartimento di Fisica e Astronomia "Galileo Galilei.) ; Barranco, Manuel (Universitat de Barcelona. Departament de Física Quàntica i Astrofísica) ; Pi, Marti (Universitat de Barcelona. Institut de Nanociència i Nanotecnologia)
Within Density Functional Theory, we have investigated the coalescence dynamics of two superfluid helium nanodroplets hosting vortex lines in different relative orientations, which are drawn towards each other by the Van der Waals mutual attraction. [...]

12 p, 1.0 MB Heat dissipation in few-layer MoS2 and MoS2/hBN heterostructure / Arrighi, Aloïs (Institut Català de Nanociència i Nanotecnologia) ; Del Corro, Elena (Institut Català de Nanociència i Nanotecnologia) ; Navarro Urrios, Daniel (Universitat Autònoma de Barcelona. Departament de Física) ; Costache, Marius Vasile (Institut Català de Nanociència i Nanotecnologia) ; Sierra, Juan F.

Advanced Materials Laboratory (Tsukuba, Japó)) ; Taniguchi, Takashi (National Institute for Material Science. Advanced Materials Laboratory (Tsukuba, Japó)) ; Garrido, Jose (Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia) ; Sledzinska, Marianna (Institut Català de Nanociència i Nanotecnologia)
State-of-the-art fabrication and characterization techniques have been employed to measure the thermal conductivity of suspended, single-crystalline MoS2 and MoS2/hBN heterostructures. Two-laser Raman scattering thermometry was used combined with real time measurements of the absorbed laser power, which allowed us to determine the thermal conductivities without any assumptions.
