Effective models of membranes from symmetry breaking
No full textWe show how to obtain all the models of the continuous description of membranes by constructing the appropriate nonlinear realizations of the Euclidean symmetries of the embedding. The procedure has the advantage of giving a unified formalism with which the models are generated and highlights the relevant order parameters in each phase. We use our findings to investigate a fluid description of both tethered and hexatic membranes, showing that both the melting and the loss of local order induce long-range interactions in the high-temperature fluid phase. The results can be used to understand the appearance of intrinsic ripples in crystalline membranes in a thermal bath

Cronache Siracusane 2016
No full textArticolo di recensione degli spettacoli organizzati dall'Istituto Nazionale del Dramma Antico, presso il teatro greco di Siracusa nella primavera del 2016. I drammi presi in considerazione sono L'Elettra di Sofocle e l'Alcesti di Euripide, per i quli si propone una comparazione tra la ricostruzione della messa in scena antica e le scelte registiche contemporanee
A different kind of four dimensional brane for string theory
No full textWe present a generalization of the string's Polyakov action that describes a
conformally invariant four dimensional brane. The new extended object is very
different from the traditional D-branes of string theory, but, nevertheless,
shares some structural similarities with the string, especially when it comes
to the low-energy limit of small tension. We introduce a rather rich structure
of tensors that can play a role at low energies. In analogy with the bosonic
string, we initiate the quantization of the new brane discussing the extent in
which it produces a critical dimension of spacetime and Einstein's equations
coupled to a scalar dilaton under some approximations.Comment: 13 pages, v2: several improvements including a new section, to appear

Encapsulation of viable animal cells for hybrid bioartificial organs by the Biosil methodProceedings of SPIE
No full textGas phase silicon alkoxides react with the wet surface of mammalian cells, affording a stable and homogeneous layer of amorphous SiO2 modified by Si-CH3 and Si-H bonds. Layer thickness may be controlled by exposure time. The layer does not suppress cell viability or functionality, and may be applied to cells supported on a trapping network or to cell aggregates. H4-II-E-C3 rat hepatoma cells, Hep G2 human cancer cells and human fibroblasts on various supports were encapsulated by the SiO2 layer and studied in terms of glucose utilization and 3H-leucin incorporation into secreted proteins. In the case of pancreatic islets, encapsulation was carried out without supports, so that original islet volume and features were maintained. In vitro results indicate preservation of vitality and function, as tested by insulin production
