This paper describes and characterises the co-occurrence of ammonite and benthic foraminiferal assemblages across the Sao Giao outcrop (Central Portugal), a reference section for the Lower-Middle Jurassic boundary in the Lusitanian Basin. The up[...]texto impreso

The notion of entropy is ubiquitous both in natural and social sciences. In the last two decades, a considerable effort has been devoted to the study of new entropic forms, which generalize the standard Boltzmann-Gibbs (BC) entropy and could be [...]texto impreso
We construct a new model of two-dimensional quantum spin systems that combines intrinsic topological orders and a global symmetry called ?avour symmetry. It is referred as the bilayer Doubled Semion model (bDS) and is an instance of symmetry-enr[...]texto impreso
Ammonoid sedimentary internal moulds can display grooves on the external or ventral region that have been formed by diverse taphonomic processes. In particular, draft-filling spiral channels and abrasion annular furrows are taphonomic structures[...]texto impreso
We derive a master equation that allows us to study non-equilibrium dynamics of a quantum antiferromagnet. By resorting to spin-wave theory, we obtain a closed analytic form for the magnon decay rates. These turn out to be closely related to for[...]texto impreso

Morganti, Michelangelo ; Assandri, Giacomo ; Aguirre de Miguel, José Ignacio ; Ramírez García, Álvaro ; Caffi, Mario ; Pulido Delgado, Francisco | Elsevier Masson | 2017-01Residency has repeatedly evolved in many migratory animals, some of which have preserved the anatomical adaptations to perform long-range movements. This is the case for partially migratory populations of Mediterranean passerines in which migran[...]texto impreso
We consider the tensors generating matrix product states and density operators in a spin chain. For pure states, we revise the renormalization procedure introduced in (Verstraete et al., 2005) and characterize the tensors corresponding to the fi[...]texto impreso
Sánchez Jardón, Laura ; Pozo Lira, Alejandro del ; Casado González, Miguel Ángel ; Ovalle, C. ; Miguel Garcinuño, José Manuel de | Elsevier Masson | 2014-02-01Grazing systems that combine grasslands and woodlands represent changes in tree cover that influences herbaceous vegetation and may threaten the native forest flora. We studied these influences in Chilean Patagonia where recent colonization resu[...]texto impreso
A multi-parametric version of the nonadditive entropy S_q is introduced. This new entropic form, denoted by S_a,b,r, possesses many interesting statistical properties, and it reduces to the entropy S_q for b=0, a=r:=1?q (hence Boltzmann–Gibbs en[...]texto impreso
Sicuro, Gabriele ; Tempesta, Piergiulio ; Rodriguez, Antonio ; Tsallis, Constantino | Elsevier Masson | 2015-12We introduce three deformations, called ?-, ?-, and ? deformation respectively, of a N-body probabilistic model, first proposed by Rodriguez et al. (2008), having q-Gaussians as N ? ? limiting probability distributions. The proposed ?- and ?-def[...]texto impreso

The ammonites assigned to the family Pseudotissotiidae of the Wiedmann (Tübingen,Germany) and Goy, Carretero and Meléndez (Madrid, Spain) collections obtained from the Iberian Trough have been revised. New, mainly lower Turonian, specimens of th[...]
