Hishiyama, N. ; Hoshino, M. ; Blanco Ramos, Francisco ; García, G. ; Tanaka, H. | IOP publishing ltd | 2017We report absolute electron elastic scattering differential cross sections (DCSs) from PF3 molecules. The crossed-beam method was used in conjunction with the relative flow technique (using helium as the reference gas) to obtain absolute values.[...]texto impreso
Bastarrachea Magnani A.; R, M. A. ; Relaño Pérez, Armando ; Lerma Hernández, S. ; López del Carpio, B. ; Chávez Carlos, J. ; Hirsch, J. G. | IOP publishing ltd | 2017-04-07Adiabatic invariants for the non-integrable Dicke model are introduced. They are shown to provide approximate second integrals of motion in the energy region where the system exhibits a regular dynamics. This low-energy region, present for any s[...]texto impreso
In this paper the Galilean, scaling and translational self-similarity conditions for the AKNS hierarchy are analysed geometrically in terms of the infinite-dimensional Grassmannian. The string equations of the one-matrix model correspond to the [...]texto impreso
We present high-fidelity, 30 mas (200 pc) resolution ALMA rest-frame 240 ?m observations of cold dust emission in three typical main-sequence star-forming galaxies (SFGs) at z ? 3 in the Hubble Ultra-Deep Field (HUDF). The cold dust is distribut[...]texto impreso
The authors present a mathematically exact formulation of the initial field striking the aperture of an absorbing optical waveguide, via an integral equation description. An analysis of the residual scattering by the waveguide is presented. Beca[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Parisi, V. ; Ruiz Lorenzo, J. J. | IOP publishing ltd | 2019-05-31Recent high precision experimental results on spin-glass films ask for a detailed understanding of the domain-growth dynamics of two-dimensional spin glasses. To achieve this goal, we numerically simulate the out-equilibrium dynamics of the Isin[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | IOP publishing ltd | 2006-12-07We calculate the induced electric stress forces on transient hydrophobic pores in the membrane of an erythrocyte exposed to an electric field. For this purpose, we use a finite element numerical technique and a realistic shape for the biconcave [...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel | IOP publishing ltd | 2001-01This paper shows the importance of using a cell model with the proper geometry, orientation and internal structure to study possible cellular effects from direct radiofrequency exposure. For this purpose, the electric field intensity is calculat[...]texto impreso
Arganda, E. ; Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2012-10The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientifi[...]texto impreso
Beltrán Jiménez, José ; Cruz Dombriz, Álvaro de la ; Dunsby, Peter K. S. ; Sáez Gómez, Diego | IOP publishing ltd | 2014-05-21One possible explanation for the present observed acceleration of the Universe is the breakdown of homogeneity and isotropy due to the formation of non-linear structures. How inhomogeneities affect the averaged cosmological expansion rate and le[...]texto impreso
Fernández Villacañas, J. L. ; Rego Fernández, Manuel ; Cornide Castro-Piñeiro, Manuel | IOP publishing ltd | 1990-06An intermediate-dispersion abundance analysis has been carried out on a sample of 21 barium and 14 comparison stars. The excess of barium over iron has been used as the most representative indicator of peculiarity. These excesses are higher in t[...]texto impreso
By means of a contactless microwave phase shift technique, the minority carrier lifetime and surface recombination velocity were measured in multicrystalline silicon wafers containing iron and chromium. The bulk lifetime can be deduced, leading [...]texto impreso
Dobado González, Antonio ; Cruz Dombriz, Álvaro de la ; López Maroto, Antonio | IOP publishing ltd | 2010In the context of f(R) gravity theories, the issue of finding static and spherically symmetric black hole solutions is addressed. Two approaches to study the existence of such solutions are considered: first, constant curvature solutions, and s[...]texto impreso
Arqueros Martínez, Fernando ; Blanco Ramos, Francisco ; García Pinto, Diego ; Minaya Flores, Ignacio Andrés ; Ortiz Ramis, Montserrat ; Rosado Vélez, Jaime ; Vázquez Peñas, José Ramón | IOP publishing ltd | 2013-05We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the lack of significant clustering in the arrival directions of the highest energy events detected at the Pierre Auger Observatory. The density of uniformly d[...]texto impreso
We compute one of the bulk viscosity coeffcients of cold color -flavor locked ( CFL) quark matter in the temperature regime where the contribution of mesons, quarks and gluons to transport phenomena is Boltzmann suppressed. In that regime dissip[...]
