Study of dental occlusion in ancient human remains: a methodological approach
(Collegium Antropologicum, 2014)The anthropological dental and maxillary study in human skeletal remains usually refers to alterations or conditions of the oral cavity. These alterations could have repercussions on life style, dietary ... -
Root canal morphology of Chalcolithic and early bronze age human populations of El Mirador Cave (Sierra de Atapuerca, Spain)
(The Anatomical Record, 2014)This study provides a morphological characterization of the inner anatomy of the root canals of permanent first and second molars in Chalcolithic and early Bronze Age human fossils using cone-beam ... -
Microscopic and virtual approaches to oral pathology: a case study from El Mirador Cave (Sierra de Atapuerca, Spain)
(Annals of Anatomy - Anatomischer Anzeiger, 2022-01)Background: The analysis and diagnosis of ancient oral pathologies have been improved with the application of new techniques such as microscopy and scanning methods over the past few decades. However, ... -

Dynamic force spectroscopy of DNA hairpins: II. Irreversibility and dissipation
(Journal of Statistical Mechanics: Theory and Experiment, 2009)We investigate irreversibility and dissipation in single molecules that cooperatively fold/unfold in a two-state manner under the action of mechanical force. We apply path thermodynamics to derive ... -
Dynamic force spectroscopy of DNA hairpins: I. Force kinetics and free energy landscapes
(Journal of Statistical Mechanics: Theory and Experiment, 2009)We investigate the thermodynamics and kinetics of DNA hairpins that fold/unfold under the action of applied mechanical force. We introduce the concept of the molecular free energy landscape and derive ... -
Work distributions in the T = 0 random field Ising model
(Physical Review E, 2008)We perform a numerical study of the three-dimensional random-field Ising model at T= 0. We compare work distributions along metastable trajectories obtained with the single-spin flip dynamics with the ... -
Investigating the thermodynamics of small biosystems with optical tweezers
(Physica E: Low-dimensional Systems and Nanostructures, 2010)We present two examples of how single-molecule experimental techniques applied to biological systems can give insight into problems within the scope of equilibrium and nonequilibrium mesoscopic ... -
Measurement of work in single-molecule pulling experiments
(The Journal of Chemical Physics, 2009)A main goal of single-molecule experiments is to evaluate equilibrium free energy differences by applying fluctuation relations to repeated work measurements along irreversible processes. We quantify ... -
Statistical properties of metastable intermediates in DNA unzipping
(Physical Review Letters, 2009)We unzip DNA molecules using optical tweezers and determine the sizes of the cooperatively unzipping and zipping regions separating consecutive metastable intermediates along the unzipping pathway. Sizes ... -
Single-molecule derivation of salt dependent base-pair free energies in DNA
(Proceedings of the National Academy of Sciences., 2010)Accurate knowledge of the thermodynamic properties of nucleic acids is crucial to predicting their structure and stability. To date most measurements of base-pair free energies in DNA are obtained in ... -
Improving signal/noise resolution in single-molecule experiments using molecular constructs with short handles
(Biophysical Journal, 2011)We investigate unfolding/folding force kinetics in DNA hairpins exhibiting two and three states with newly designed short dsDNA handles (29 bp) using optical tweezers. We show how the higher stiffness ... -
Single-molecule stochastic resonance
(Physical Review X, 2012)Stochastic resonance (SR) is a well-known phenomenon in dynamical systems. It consists of the amplification and optimization of the response of a system assisted by stochastic (random or probabilistic) ... -
Counter-propagating dual-trap optical tweezers based on linear momentum conservation
(Review of Scientific Instruments, 2013)We present a dual-trap optical tweezers setup which directly measures forces using linear momentum conservation. The setup uses a counter-propagating geometry, which allows momentum measurement on each ... -
Derivation of nearest-neighbor DNA parameters in magnesium from single molecule experiments
(Nucleic Acids Research, 2017)DNA hybridization is an essential molecular reaction in biology with many applications. The nearest-neighbor (NN) model for nucleic acids predicts DNA thermodynamics using energy values for the different ... -

La alteridad mal explicada: una visión alternativa sobre el problema de las otras mentes
(Naturaleza y Libertad. Revista De Estudios Interdisciplinares, 2016)Tomando como punto de partida la tesis de Arana en La conciencia inexplicada(de que la conciencia es inexplicable por métodos naturalistas), la ponencia defiende una visión de la capacidad de alteridad ... -
Perennialism through the lens of otherness
(International Journal of Transpersonal Studies, 2020)Otherness has been a subject of the utmost relevance for continental philosophy since the beginning of the 20th century, constituting what might be characterized as an otherness turn. Otherness is here ...
