theory goes time-dependentThe scope of time-dependent density-functional theory (TDDFT) is limited to the lowest portion of the spectrum of rather small systems (a few tens of atoms at most). In the static regime, density-functional perturbation theory (DFPT) allows one to calculate response functions of systems as large as currently dealt with in ground-state simulations. In this paper we present an effective way of combining DFPT with TDDFT. The dynamical polarizability is first expressed as an off-diagonal matrix element of the resolvent of the Kohn-Sham Liouvillian super-operator. A DFPT representation of response functions allows one to avoid the calculation of unoccupied Kohn-Sham orbitals. The resolvent of the Liouvillian is finally conveniently evaluated using a newly developed non-symmetric Lanczos technique, which allows for the calculation of the entire spectrum with a single Lanczos recursion chain. Each step of the chain essentially requires twice as many operations as a single step of the iterative diagonalization of the unperturbed Kohn-Sham Hamiltonian or, for that matter, as a single time step of a Car-Parrinello molecular dynamics run. The method will be illustrated with a few case molecular applications.Stefano BaroniDario RoccaRalph Gebauer2009-11-26Z2010-04-13T11:14:47Zhttp://cab.unime.it/mus/id/eprint/539This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5392009-11-26ZStatistical entropy and clustering in absence of attractive terms in the interparticle potentialRecently a new intriguing class of systems has been introduced, the so-called generalized exponential models, which exhibit clustering phenomena even if the attractive term is missing in their interaction potential. This model is characterized by a index n which tunes the repulsive penetrability of the potential. This family of potentials can represent the effective interactions for a large number of soft matter systems. In this paper we study the structural and thermodynamic properties in the fluid regime of the generalized exponential model with a value of index n suggested by Mladek et al. [B. M. Mladek, G. Kahl, and C. N. Likos, Phys. Rev. Lett. (2008)] to fit the effective potential of a typical amphiphilic dendrimers. We use the conventional approach of the liquid state theory based on the hypernetted chain closure of the Ornstein-Zernike equation together with some Monte Carlo numerical simulations. Moreover, we try to detect qualitatively the freezing line exploiting the predictive properties of a one-phase rule based on the expansion of the statistical entropy.Franz Saija2009-11-26Z2010-04-13T11:14:48Zhttp://cab.unime.it/mus/id/eprint/540This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5402009-11-26ZHarmonic wavelet solution of Poisson's problem with a localized sourceA method, based on a multiscale (wavelet) decomposition of the solution is proposed for the analysis of the Poisson problem. The solution is approximated by a finite series expansion of harmonic wavelets and is based on the computation of the connection coefficients. It is shown, how a sourceless Poisson's problem, solved with the Daubechies wavelets, can also be solved in presence of a localized source in the harmonic wavelet basis.Carlo Cattani2009-11-26Z2010-04-13T11:14:50Zhttp://cab.unime.it/mus/id/eprint/541This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5412009-11-26ZThe absorbed energy in the Shroud body image formation appears as contributed by discrete valuesStarting from the optical density distribution in the Shroud body image and without any assumption on the mechanism that acts at a distance, we deduce that the absorbed energy by the Linen of Turin, related to the human body shape presence, is due to the contribution of discrete energy values.Giovanni FazioGiuseppe Mandaglio2009-11-26Z2010-04-13T11:14:41Zhttp://cab.unime.it/mus/id/eprint/542This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5422009-11-26ZDoes an I(z) correlation exist for the back-part of the Shroud body image?Nowadays it is not known if an I(z) correlation exists for the back-part of the Shroud body image. This occurs because it is difficult to measure the cloth-body distances and to correlate them with the intensities of the image. By a scientific analysis we find a correlation with a slope that is different from the one related to the front-part of the above image.Giovanni FazioGiuseppe Mandaglio2009-11-26Z2010-04-13T11:14:43Zhttp://cab.unime.it/mus/id/eprint/543This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5432009-11-26ZThermodynamics of semiconductors with impuritiesIn this paper we construct a geometric model for the thermodynamics of semiconductors with impurities, using a nonconventional model based on the extended irreversible thermodynamics with internal variables. For this purpose, we derive the transformation induced by the process and the dynamical system for a \textit{simple material element} of extrinsic semiconductors. Finally, we obtain the expressions for the entropy function, the necessary conditions for its existence and the entropy 1-form, starting point to investigate an extended thermodynamical phase space.Maria Paola MazzeoLiliana Restuccia2009-11-26Z2010-04-13T11:14:45Zhttp://cab.unime.it/mus/id/eprint/544This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5442009-11-26ZStructures on the space of financial eventsIn this paper we endow the space of financial events with some structures, each of them represents basic facts of financial mathematics. We introduce a preordered structure, that we shall call the usual preorder of the financial events plane, and an algebraic structure, that we call the usual linearoid structure of the financial events plane. The algebraic structures introduced are not void of properties: the usual addition will confer to the space a gruppoid structure and the multiplication by scalars will be a law of action associative and distributive with respect to the addition. We shall prove that these structures are compatible among them and with the standard topology of the plane. Then we show the possibility of defining new (economically relevant) preorders by the use of capitalization factors and that there is a manner (the conjunction) to obtain the usual preorder from infinite continuous families of these new preorders induced by a capitalization factor.David Carfì2009-11-26Z2012-09-20T08:24:06Zhttp://cab.unime.it/mus/id/eprint/545This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5452009-11-26ZRicerche sulla biodiversità delle comunità batteriche in tre laghi antartici The bacterial diversity in three Antarctic lakes located at Crater Cirque (CC), Inexpressible Island (INI) and Luther Peak (LH) in the Victoria Land was investigated by a combination of culture-dependent and culture-independent techniques. The in situ abundance of different bacterial groups was determined by fluorescent in situ hybridization (FISH), while bacterial diversity among the cultivable microflora was investigated by culturing and genetic fingerprinting. Differences in the composition of bacterial assemblages were observed among the lakes investigated, when using the two approaches reported above. Overall, the detection rate by FISH of DAPI-stained cells varied from 48.4% to 68.9% with the general bacterial probe EUB338. Bacteria hybridizing with the group-specific probe CF319a were found to be abundant in the three lakes. A total of 478 strains were isolated from R2A agar plates and grouped by restriction analysis technique; sequencing of representative 16S rDNAs was performed to elucidate the taxonomic positions of isolates. Overall, isolates were placed within five different taxa: ?-Proteobacteria (39%), Bacteroidetes (35%), ?-Proteobacteria (8%), Actinobacteria (7%) and ?-Proteobacteria (5%). Finally, the 5.8% of total isolates shared the highest degree of sequence identity with unclassified bacteria. Members of the ?-Proteobacteria predominated at INI, whereas isolates from CC and LH mainly belonged to the Bacteroidetes. Among the ?-Proteobacteria, the genus Pseudomonas was predominant, whereas Flavobacterium spp. were very common among the Bacteroidetes. Finally, several Actinobacteria were closely related to unknown Antarctic bacteria.Luigi MichaudAngelina Lo GiudiceConsolazione CarusoSantina ManganoVivia Bruni2009-11-26Z2010-04-13T11:14:38Zhttp://cab.unime.it/mus/id/eprint/546This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5462009-11-26ZArchimede aristotelico o platonico: "tertium non datur"? The aim of the present paper is to continue a critical study on Hellenistic Sciences. Such a study began with some previous papers on Euclid, where some remarkable aspects of the Alexandrinian mathematician emerged; in particular, we focused on some characters, innovative with respect to the previous Greek philosophical tradition and undervalued until now by historiography and critical literature. Here, the figure of Archimedes is analysed in the light of previous results and consequent criteria; he is freed from a long tradition, started with Plutarch, that sees the Sicilian scientist inside a Platonistic (in some sense) paradigm or, inversely, in an Aristotelian one. The re-reading of his works in the light of the new hypotheses, as expressed by other authors and scholars, allows us to delineate a more pragmatic and modern figure of scientist. In particular, some metaphysical problems as those concerning the Truth and Prime Causes, that were central in the Platonic-Aristotelian tradition, are in such a way avoided or suspended, in favour of more exact and appropriate modelling tools that make the phenomenical world more predictable and controllable also by technologies.Giuseppe GentileRenato Migliorato2009-11-26Z2010-04-13T11:14:40Zhttp://cab.unime.it/mus/id/eprint/547This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5472009-11-26ZAristosseno tra aristotelismo e nuova scienzaThe Armonica of Aristoxenus is re-read in the light of a paper by F. Bellissima [Nuncius, XVII, n.1, 2-44 (2002)] that emphasizes its basically deductive structure, although with some limitations at a strictly logical level. We further address some problems recently posed by R. Migliorato, G. Gentile and L. Russo. In particular, Migliorato introduced the expression Euclidean revolution to denote a change in the scientific paradigm with respect to the Aristotelian conception, which, on the ground of extant texts, is observed for the first time in the Euclidean works. Since very few textual sources are available, Migliorato remained prudent as to the total attribution of the perspective change. The analysis carried out here discloses an attempt to overcome the Pitagorean dogmatism already in Aristoxenus, as well as the metaphysical foundation of the Aristotelian deductive science, without however enacting in a clear way the epistemological step that we can observe in Euclid. Such a process partially merges into the Euclidean revolution as formulated by Migliorato.Alessandro Sarritzu2009-11-26Z2010-04-13T11:14:32Zhttp://cab.unime.it/mus/id/eprint/548This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5482009-11-26ZAdaptive web data extraction policiesWeb data extraction is concerned, among other things, with routine data accessing and downloading from continuously-updated dynamic Web pages. There is a relevant trade-off between the rate at which the external Web sites are accessed and the computational burden on the accessing client. We address the problem by proposing a predictive model, typical of the Operating Systems literature, of the rate-of-update of each Web source. The presented model has been implemented into a new version of the Dynamo project: a middleware that assists in generating informative RSS feeds out of traditional HTML Web sites. To be effective, i.e., make RSS feeds be timely and informative and to be scalable, Dynamo needs a careful tuning and customization of its polling policies, which are described in detail.Giacomo FiumaraMassimo MarchiAlessandro Provetti2009-06-25Z2013-04-03T09:52:58Zhttp://cab.unime.it/mus/id/eprint/514This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/5142009-06-25ZMental disorders and request for psychiatric intervention in an Italian local jailThe issue of the prevalence of psychiatric illnesses in Italian prison samples has not received the same attention paid at an international level. The aims of the present study were to evaluate the prevalence of psychiatric disorders diagnosed according to DSM-III-R criteria among an Italian prisoner population, and to examine prisoners' requests for psychiatric intervention in relationship to the presence or absence of different psychiatric disorders. One hundred fortytwo Italian male subjects from the Casa Circondariale of Messina, Italy, were evaluated using the
Structured Clinical Interviewfor DSM-III-R Non-Patient Version Â—SCID I and SCID II. Avery high rate of disorders was found among inmates: 85.2% (n=121) of the sample were affected by a psychiatric disorder. Of the total sample, 51.4% (n=73) had requested psychiatric treatment during detention. The detection, diagnosis and treatment of the mentally ill prisoners is a primary goal for a better organization of services and prison settings; screening procedures for evaluating the presence of psychiatric disorders, with the aim to promote differential strategies
for the care and rehabilitation of inmates, are needed.Rocco A. ZoccaliMaria R. A. MuscatelloAntonio BrunoR. CambriaL. CavallaroG. D'AmicoS. IsgròV.

Recent developments on fiber probes for Scanning Near Field Optical Microscope are reported. In this frame, new models and prototypes of probes with higher performances in terms of optical power efficiency and polarization selectivity are worked out. A new fabrication method of the probes is settled, based on a chemical etching process, which doubles the aspect ratio of the probe sharpness and improves the optical throughput. Moreover, Finite Domain Time Difference simulation allows the designing of a probe able to act as an evanescent field linear polarizer.

First of all the Pareto boundaries are the first and most important generalization of the concept of optimum; on the other hand, if f is a real functional defined on a non empty set X and K is a part of X, the determination of the optimal boundaries of the part K with respect to some preorder ? of X for which f is strictly increasing permits to reduce the optimization problem (f, K, inf) (or (f, K, sup)) to the problem (f, minP(K), inf) (resp. (f, maxP(K), sup)), where by minP(K) we denoted the minimal boundary of K (that in general is greatly smoller than K).

In this way we are able to prove that the specific load connected to the sixth distortion and examined as external stress, is equivalent (in Saint Venant's theory) to a right combined compressive and bending stress (or to a right combined tensile and bending stress).

The paper can be referred to that direction in the wavelet theory, which was called by Kaiser "the physical wavelets". He developed the analysis of first two kinds of physical wavelets - electromagnetic (optic) and acoustic wavelets. Newland developed the technique of application of harmonic wavelets especially for studying the harmonic vibrations. Recently Cattani and Rushchitsky proposed the 4th kind of physical wavelets - elastic wavelets. This proposal was based on three main elements: 1. Kaiser's idea of constructing the physical wavelets on the base of specially chosen (admissible) solutions of wave equations. 2. Developed by one of authors theory of solitary waves (with profiles in the form of Chebyshov-Hermite functions) propagated in elastic dispersive media. 3. The theory and practice of using the wavelet "Mexican Hat" system, the mother and farther wavelets (and their Fourier transforms) of which are analytically represented as the Chebyshov-Hermite functions of different indexes. An application of elastic wavelets to studying the evolution of solitary waves of different shape during their propagation through composite materials is shown on many examples.

In particular, for dielectric relaxation we assume a sinusoidal form for induction vector (extensive variable: cause), the electric field (intensive variable: effect) inside the system, which depends on unknown phenomenological coefficients, has been obtained by integration. Then we compare it with a similar form of the electric field obtained by experimental considerations, where well known experimentally determinable coefficients appear. We carry out dielectric measurements on PMMA and PVC at different frequencies and fixed temperature in order to obtain the phenomenological coefficients as functions of the frequency. For viscoanelastic media we consider the relative rheological equation and we compare the solution of this equation with a well known expression of the stress obtained, by experimentally considerations, in the linear response theory. This comparison will be able to determine the phenomenological an state coefficients as function of frequency dependent quantities experimentally measurable. This method will be applied to polymeric materials as Polyisobutilene.

The relations between different proposals are explicitly examined in two especially simple systems: an ideal gas in steady shear flow and a forced harmonic oscillator in a thermal bath. We examine with special detail temperatures related to the average molecular kinetic energy along different spatial directions, to the average configurational energy, to the derivative of the entropy with respect to internal energy, to fluctuation-dissipation relation and discuss their measurement.

In a previous paper, in a geometrized framework for the description of simple materials with internal variables, the specific example of ferroelastic crystals with anisotropy grain-tensors Ã la Maruszewski was considered and the relevant structure of the entropy 1-form was derived. In this contribution the linear morphism defined on the fibre bundle of the process and the transformation induced by the process are obtained as new results within the geometrical model. Furthermore, Clausius-Duhem inequality for these media is exploited, and, using a Maugin technique (see also Colemann-Noll procedure), the laws of state, the extra entropy flux and the residual dissipation inequality are worked out. Finally, following Maugin, the heat equation in the first and the second form are derived.

Applying Liu's procedure results in the class of materials and a differential equation both belonging to the close-to-Fourier case of heat conduction.

The theoretical description of this phenomenon is patterned after the thermodynamic and mesoscopic modeling of the orientational dynamics and the flow behavior of liquid crystals in the isotropic and nematic phases, where the theoretical basis is well-established. Even there the solutions of the relevant equations recently yielded surprises: not only stable flow alignment and a periodic behavior (tumbling) are found as response to an imposed stationary shear flow but also irregular and chaotic dynamics occurs for certain parameter ranges. To treat shear-thickening fluids, a non-linear Maxwell model equation for the symmetric traceless part of the stress tensor has been proposed in analogy to the equations obeyed by the alignment tensor of nematics. The fluid-solid transition is formally analogous to the isotropic-nematic transition. In addition to shear-thickening and shear-thinning fluids, substances with yield stress can be modeled. Furthermore, periodic stick-slip-like motions and also chaotic behavior are found. In the latter cases, the instantaneous entropy production is not always positive. Yet it is comforting that its long-time average is in accord with the second law.

Approaching the reversible regime means to become more and more quasistatic, letting behind processes which achieve any kind of finite transformation rate for the quantities studied. On the other hand studying processes with finite transformation rates means to deal with irreversibilities and in many cases these irreversibilities must be included in a realistic description of such processes. Endoreversible thermodynamics is a non-equilibrium approach in this direction by viewing a system as a network of internally reversible (endoreversible) subsystems exchanging energy in an irreversible fashion. This material provides an introduction to the subject.

The proposal is based on an extension of the body model region to the whole space where the space integral as a particular solution to the initial-boundary value problem is derived. Temperature component is separated from the space integral. The component admissibility conditions are formulated. For numerical purposes the approximated integral with a discrete set of fictitious components is proposed. The fictitious component intensities are determined on an approximate way from the boundary condition. An approximate solution of the heat conduction problem is obtained by extension in time and contraction in space of the approximated integral.

The systematic description offered by classical non-equilibrium thermodynamics theory, when extended to surfaces, gives the interaction between the two fluxes in terms of coupling coefficients. It is shown in this paper that these coupling coefficients are large. The few experimental and computational results that are available confirm this. Neglect of coupling coefficients, which is common in most models for surface transport, may lead to errors in the heat flux. We present values for the coupling coefficient in a one-component system in terms of the heat of transfer, as obtained from non-equilibrium molecular dynamics simulations, kinetic theory and the integrated non-equilibrium van der Waals' square gradient model.Signe KjelstrupDick Bedeaux2008-01-28Z2010-04-13T11:16:42Zhttp://cab.unime.it/mus/id/eprint/463This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/4632008-01-28ZA stress field in the vortex lattice in the type-II superconductor Magnetic flux can penetrate a type-II superconductor in the form of Abrikosov vortices (also called flux lines, flux tubes, or fluxons), each carrying a quantum of magnetic flux. These tiny vortices of supercurrent tend to arrange themselves in a triangular and/or quadratic flux-line lattice, which is more or less perturbed by material inhomogeneities that pin the flux lines. Pinning is caused by imperfections of the crystal lattice, such as dislocations, point defects, grain boundaries, etc. Hence, a honeycomb-like pattern of the vortex array presents some mechanical properties. If the Lorentz force of interactions between the vortices is much bigger than the pinning force, the vortex lattice behaves elastically. So we assume that the pinning force is negligible in the sequel and we deal with soft vortices. The vortex motion in the vortex lattice and/or creep of the vortices in the vortex fluid is accompanied by energy dissipation. Hence, except for the elastic properties, the vortex field is also of a viscous character. The main aim of the paper is a formulation of a thermoviscoelastic stress - strain constitutive law consisted of coexistence of the ordered and disordered states of the vortex field. Its form describes an auxetic-like thermomechanical (anomalous) property of the vortex field.Bogdan Maruszewski2008-01-28Z2010-04-13T11:16:34Zhttp://cab.unime.it/mus/id/eprint/464This item is in the repository with the URL: http://cab.unime.it/mus/id/eprint/4642008-01-28ZOn the objectivity of time derivaties A four-dimensional treatment of nonrelativistic space-time gives a natural frame to deal with objective time derivatives. In this framework some well known objective time derivatives of continuum mechanics appear as Lie-derivatives. Their coordinatized forms depends on the tensorial properties of the relevant physical quantities.

Accordingly, their realm is the material manifold of a body. Furthermore, they acquire a physical meaning only in so far as they contribute to the global dissipation. Therefore, the present contribution of a pedagogical nature proposes a primer introduction to the thermodynamics of configurational forces. To that purpose, we first introduce a consistent thermomechanics of general deformable continua on the material manifold (and not in physical space). This is achieved in a canonical manner by full projection of the balance equation of momentum onto the material manifold and constructing in parallel a formally consistent expression of the energy conservation. Then various configurational forces such as those appearing in inhomogeneous bodies, at the tip of a propagating crack, at the surface of a propagating phase-transition front, or of a shock wave, and those due to local structural rearrangements (plasticity, damage, growth), are examined from the point of view of their dissipated power.

Mrugala and the geometry of thermodynamical phase space We study an indefinite metric G which was introduced by R. Mrugala and is defined on the contact phase space (P,?) of a homogeneous thermodynamical system. We describe the curvature properties and the isometry group of the metric G. We established an isomorphism of the space (P,?,G) with the Heisenberg Lie group Hn, endowed with the right invariant contact structure and the right invariant indefinite metric. The lift of the metric G to the symplectization of contact space (P,?) and its properties are studied. Finally we introduce the "hyperbolic projectivization" of the space () that can be considered as the natural compactification of the thermodynamical phase space (P, q, G).

Thermodynamics provides the basis for understanding how heat and work are related and with the general rules that the macroscopic properties of systems at equilibrium follow. Outside equilibrium and away from macroscopic regimes most of those rules cannot be applied directly. In this paper we present recent developments that extend the applicability of thermodynamic concepts deep into mesoscopic and irreversible regimes. We show how the probabilistic interpretation of thermodynamics together with probability conservation laws can be used to obtain kinetic equations describing the evolution of the relevant degrees of freedom. This approach provides a systematic method to obtain the stochastic dynamics of a system directly from the knowledge of its equilibrium properties. A wide variety of situations can be studied in this way, including many that were thought to be out of reach of thermodynamic theories, such as non-linear transport in the presence of potential barriers, activated processes, slow relaxation phenomena, and basic processes in biomolecules, like translocation and stretching.

An extremal principle is formulated for thermodynamic systems near equilibrium subjected to various external conditions. It is shown that the principle describes unambiguously the kinetics of the thermodynamic system and replaces classical phenomenological equations. Thus the principle can be considered as an effective tool for the treatment of non-equilibrium thermodynamic systems. In two examples the principle is used for the description of Dufour and Soret effects and plasticity.

Gyarmati's wave approach leads to a solution fitting to the classical term in the low frequency regime. A shortage of the solution is that the characteristic time in the equation depends on the mass of the charged particle. An abstract model with two dynamic degrees of freedom results in a solution free of the above problem. For complete compatibility with electrodynamics, the need for a generalization of Maxwell's equations is probable.
