Multiphoton Absorption of Myoglobin Nitric-Oxide complex: Relaxation by D-NEMD of a Stationary State
2012
ABSTRACT: The photodissociation and geminate recombination of nitric oxide in myoglobin, under continuous illumination, is modeled computationally. The relaxation of the photon energy into the protein matrix is also considered in a single simulation scheme that mimics a complete experimental setup. The dynamic approach to non-equilibrium molecular dynamics is used, starting from a steady state, to compute its relaxation to equilibrium. Simulations are conducted for the native form of sperm whale myoglobin and for two other mutants, V68W and L29F, illustrating a fair diversity of spatial and temporal geminate recombination processes. Energy flow to the heme and immediate protein environment …

Prevención de caídas y fracturas mediante un programa de ejercicios para pacientes con osteoporosis y osteopenia
2013
INTRODUCCIÓN: La osteoporosis es una enfermedad generalizada del sistema esquelético con una disminución de la densidad mineral ósea, con un mayor riesgo de padecer fracturas. Representa un elevado impacto sobre el presupuesto global sanitario. En aras de disminuir la factura económica y para mejorar la calidad de vida de los pacientes, la prevención es fundamental. OBJETIVOS: - Demostrar que la práctica de un programa de ejercicios pautados durante un periodo de 9 meses en población mayor de la comunidad conlleva una disminución de la prevalencia de caídas y fracturas, gracias a mejorar el equilibrio, estabilidad de la marcha, riesgo de padecer caídas, dolor y calidad de vida. - Estudiar d…
Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
Improvement of partition coefficients determination of aroma compounds in food matrices by the phase ratio variation method
2011
The Phase Ratio Variation (PRV) method is a very valuable method commonly used for liquid/vapor partition coefficients data acquisition of aroma compounds. Nevertheless, some limits are linked to this method, especially for volatile compounds. A careful examination of the PRV equation leads us to propose the following expression: 1/Cvap-real =(nliq/n0) x 1/Cvap-ideal = (nliq/n0) x (1/KC0 + (1/Co) b), We performed an examination for two cases of K values (K1=0.001 and K2=0.05), putting forward that a carefully choice of b range values is crucial for reliability of the regression calculation 1/A versus b.
Unraveling the nature of universal dynamics in O(N) theories
2020
Many-body quantum systems far from equilibrium can exhibit universal scaling dynamics which defy standard classification schemes. Here, we disentangle the dominant excitations in the universal dynamics of highly occupied N-component scalar systems using unequal-time correlators. While previous equal-time studies have conjectured the infrared properties to be universal for all N, we clearly identify for the first time two fundamentally different phenomena relevant at different N. We find all N >= 3 to be indeed dominated by the same Lorentzian "large-N" peak, whereas N = 1 is characterized instead by a non-Lorentzian peak with different properties, and for N = 2, we see a mixture of two cont…
Socially-aware Dynamic Computation Offloading Scheme for Fog Computing System with Energy Harvesting Devices
2018
Fog computing is considered as a promising technology to meet the ever-increasing computation requests from a wide variety of mobile applications. By offloading the computation-intensive requests to the fog node or the central cloud, the performance of the applications, such as energy consumption and delay, are able to be significantly enhanced. Meanwhile, utilizing the recent advances of social network and energy harvesting (EH) techniques, the system performance could be further improved. In this paper, we take the social relationships of the EH mobile devices (MDs) into the design of computational offloading scheme in fog computing. With the objective to minimize the social group executi…
Leggere, scrivere, presentare
2021
La manifestazione “Pioggia di Libri” nasce da un’idea di Andrea Sciascia, prima Coordinatore del Corso di Studi in Architettura e poi Direttore del Dipartimento di Architettura di Palermo. L’obiettivo è quello di divulgare le attività didattiche e di ricerca condotte dai docenti del Dipartimento di Architettura alla comunità scientifica universitaria e non solo, in modo da attivare una virtuosa circolazione di informazioni e idee. Gli attori principali sono gli studenti che frequentano i Corsi di Laurea del Dipartimento e i Dottorandi. La formula è semplice ma efficace: come in una pièce teatrale, la presentazione di uno o più libri avviene attraverso un relatore senjor (professore UNIPA o …
