2P-111 Stochastic resonance in DNA hairpins(The 46th Annual Meeting of the Biophysical Society of Japan)
(Seibutsu Butsuri, 2008) -
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 ... -
Nonequilibrium thermodynamics of single DNA hairpins in a dual-trap optical tweezers setup
(AIP Conference Proceedings, 2011)We use two counter propagating laser beams to create a dual trap optical tweezers setup which is free from cross interference between the beams and provides great instrumental stability. This setup works ... -
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 ... -
Editorial for “Psychophysical Evaluation of Visual vs. Computer Aided Detection of Brain Lesions on Magnetic Resonance Images”
(Journal of Magnetic Resonance Imaging, 2022) -
Radiology as the base player
(Radiología, 2023) -
Not everything is as it seems: Todd paralysis
(Anales de Pediatría, 2024) -
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 ...
