Water and membrane dynamics in suspensions of lipid vesicles functionalized with poly(ethylene glycol)s
(2014-05-08)
The present work was aimed at studying the molecular dynamics at different levels of model membranes having a simulated glycoclix, with focus on the molecular crowding conditions at the lipid–water interfacial region. Thus, ...
The growth of ice particles in a mixed phase environment based on laboratory observations
(2014)
This paper describes new laboratory observations about the size evolution of ice crystals and cloud droplets immersed in a mixed-phase cloud. The experiments were performed by using a cloud chamber facility for three ...
Experimental quantification of decoherence via the Loschmidt echo in a many spin system with scaled dipolar Hamiltonians
(2015)
We performed Loschmidt echo nuclear magnetic resonance experiments to study decoherence under a scaled dipolar Hamiltonian by means of a symmetrical time-reversal pulse sequence denominated Proportionally Refocused Loschmidt ...
New geometries for the characterization of dark matter phenomena
(2014)
We present some new geometries with spheroidal symmetry, with and without mass, that involve new kind of energy momentum tensors, and which are suitable for the description of dark matter phenomena.
Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005-2010
(2014)
We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ...
Asymptotic structure of the null surface formulation and the classical graviton
(2016)
The dynamical equations for the null surface formulation of general relativity for purely radiative spacetimes are derived. Those asymptotically flat spacetimes describe the nonlinear evolution of gravitational radiation ...
High resolution, week-long, locomotion time series from Japanese quail in a home-box environment
(2016-06-07)
Temporal and spatial patterns of locomotion reflect both resting periods and the movement from one place to another to satisfy physiological and behavioural needs. Locomotion is studied in diverse areas of biology such as ...
The index of symmetry of compact naturally reductive spaces
(2014)
We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
Layered double hydroxides-indomethacin nanohybrids : intercalation, pH influence, stability and release properties
(2016)
In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage ...
Development of a design model for functionality and content access from rich internet application requirements
(2015)
We have found several methodologies for the development of rich internet applications (RIA); however, they did not give enough attention to the problem of defining both appropriate notations and adequate process for ...
