description: We have obtained extensive high-quality spectroscopic observations of the OGLE-LMC-CEP-1718 eclipsing binary system in the Large Magellanic Cloud which Soszynski et al. (2008) had identified as a candidate system for containing two classical Cepheids in orbit. Our spectroscopic data clearly demonstrate binary motion of the Cepheids in a 413-day eccentric orbit, rendering this eclipsing binary system the first ever known to consist of two classical Cepheid variables. After disentangling the four different radial velocity variations in the system we present the orbital solution and the individual pulsational radial velocity curves of the Cepheids. We show that both Cepheids are extremely likely to be first overtone pulsators and determine their respective dynamical masses, which turn out to be equal to within 1.5 %. Since the secondary eclipse is not observed in the orbital light curve we cannot derive the individual radii of the Cepheids, but the sum of their radii derived from the photometry is consistent with overtone pulsation for both variables. The existence of two equal-mass Cepheids in a binary system having different pulsation periods (1.96 and 2.48 days, respectively) may pose an interesting challenge to stellar evolution and pulsation theories, and a more detailed study of this system using additional datasets should yield deeper insight about the physics of stellar evolution of Cepheid variables. Future analysis of the system using additional near-infrared photometry might also lead to a better understanding of the systematic uncertainties in current Baade-Wesselink techniques of distance determinations to Cepheid variables.

Τα είδη ελάτης παίζουν σημαντικό οικολογικό ρόλο στις περιοχές που έχουν φυσική εξάπλωση. Πάρα πολλά από τα είδη ελάτης είναι σημαντικά για την παραγωγή ξυλείας και καλλιεργούνται και εκτός των περιοχών φυσικής τους εξάπλωσης.  Άλλα είδη ελάτης θεωρούνται κατάλληλα ως καλλωπιστικά σε αισθητικές φυτεύσεις. Τα δένδρα ελάτης θεωρούνται κατάλληλα για Χριστουγεννιάτικα δένδρα, εξαιτίας του κωνικού τους σχήματος, του χρώματος της κόμης, των ισχυρών τους κλάδων, στα οποία μπορούν να κρεμαστούν στολίδια, ιδιαίτερα τα είδη που παρουσιάζουν άριστη διατήρηση των βελονών τους μετά την κοπή. Στην Ευρώπη, το πιο κοινό είδος που χρησιμοποιείται ως Χριστουγεννιάτικο δένδρο είναι το Abies nordmanniana, ενώ στις ΗΠΑ επικρατούν στην αγορά τα είδη A.fraseri και A.procera.  Άλλα είδη που είναι εμπορεύσιμα ως Χριστουγεννιάτικα δένδρα είναι: Abies balsamea, A. grandis, A. koreana, A. sibirica, A. lasiocarpa, A. bornmuelleriana και A. concolor. Το κυριότερο όμως είδος για την παραγωγή κομμένων κλάδων για τα Χριστούγεννα σε Ευρώπη και ΗΠΑ είναι το Abies procera.

description: Owing to a number of reasons, the deployment of encryption solutions are beginning to be ubiquitous at both organizational and individual levels. The most emphasized reason is the necessity to ensure confidentiality of privileged information. Unfortunately, it is also popular as cyber-criminals' escape route from the grasp of digital forensic investigations. The direct encryption of data or indirect encryption of storage devices, more often than not, prevents access to such information contained therein. This consequently leaves the forensics investigation team, and subsequently the prosecution, little or no evidence to work with, in sixty percent of such cases. However, it is unthinkable to jeopardize the successes brought by encryption technology to information security, in favour of digital forensics technology. This paper examines what data encryption contributes to information security, and then highlights its contributions to digital forensics of disk drives. The paper also discusses the available ways and tools, in digital forensics, to get around the problems constituted by encryption. A particular attention is paid to the Truecrypt encryption solution to illustrate ideas being discussed. It then compares encryption's contributions in both realms, to justify the need for introduction of new technologies to forensically defeat data encryption as the only solution, whilst maintaining the privacy goal of users.

description: We present the results of a survey using the WASP archive to search for high frequency pulsations in F-, A- and B-type stars. Over 1.5 million targets have been searched for pulsations with amplitudes greater than 0.5 millimagnitude. We identify over 350 stars which pulsate with periods less than 30 min. Spectroscopic follow-up of selected targets has enabled us to confirm 10 new rapidly oscillating Ap stars, 13 pulsating Am stars and the fastest known $δ$ Scuti star. We also observe stars which show pulsations in both the high-frequency domain and in the low-frequency $δ$ Scuti range. This work shows the power of the WASP photometric survey to find variable stars with amplitudes well below the nominal photometric precision per observation.

description: This article analyzes topographical and geological settings in the Japan Archipelago for comparative raster data processing using GRASS GIS. Data include bathymetric and geological grids in NetCDF format: GEBCO, EMAG2, GlobSed, marine free‐air gravity anomaly and EGM96. Data were imported to GRASS by gdalwarp utility of GDAL and projected via PROJ library. Methodology includes data processing (projecting and import), mapping and spatial analysis. Visualization was done by shell scripting using a sequence of GRASS modules: ‘d.shade’ for relief mapping, ‘r.slope.aspect’; for modelling based on DEM, ‘r.contour’ for plotting isolines, ‘r.mapcalc’ for classification, ‘r.category’ for associating labels, and auxiliary modules (d.vect, d.rast, d.grid, d.legend). The results of the geophysical visualization show that marine free‐air gravitational anomalies vary in the Sea of Japan (–30 to above 40 mGal) reflecting density inhomogeneities of the tectonic structure, and correlating with the geological structure of the seafloor. Dominating values of geoid model are 30–45 m reflecting West Pacific rise, determined by deep density inhomogeneities associated with the mantle convention. Sediment thickness varies across the sea reflecting its geological development with density of 2 km in its deepest part and thinner in central part (Yamato Rise). The aspect map and reclassified map express gradient of the steepest descent.

Non-deterministic dynamics of a mechanical system

description: A mechanical system is presented exhibiting a non-deterministic singularity, that is, a point in an otherwise deterministic system where forward time trajectories become non-unique. A Coulomb friction force applies linear and angular forces to a wheel mounted on a turntable. In certain configurations the friction force is not uniquely determined. When the dynamics evolves past the singularity and the mechanism slips, the future state becomes uncertain up to a set of possible values. For certain parameters the system repeatedly returns to the singularity, giving recurrent yet unpredictable behaviour that constitutes non-deterministic chaotic dynamics. The robustness of the phenomenon is such that we expect it to persist with more sophisticated friction models, manifesting as extreme sensitivity to initial conditions, and complex global dynamics attributable to a local loss of determinism in the limit of discontinuous friction.

Organisational hierarchies in English universities: understanding roles and boundaries
Creators: name: Catterall, Nicholas
Publisher: name: Lancaster University
Year: 2020

description: This research seeks to advance understanding of senior roles and the boundaries between them in contemporary English universities. Analysing interviews with senior managers at eight different English universities, the research presents findings in support of the view that managerialism and professionalisation continue to shape senior leadership teams. The ‘roles and boundaries’ in the title of this research are drawn from the descriptions of participants who discuss their roles in terms of portfolio, and the boundaries of where their remit meets that of their colleagues as a process of negotiation in response to circumstances. Grouped under three overarching themes (Sense of place, Drawing authority to lead, and Influencing change), the findings show participants describing strong collegial working at the executive level, blurred boundaries between the roles of senior managers, and an advancement of professionalisation at their institutions through the use of management information and plans to implement management training programmes. The academic mission is shown to be no less important but concerns for long-term sustainability of the organisation are seen to be shaping decisions, and in turn expanding the boundaries of professional managers into areas long seen as the domain of their academic colleagues. In doing so, the boundaries of roles at the senior executive level are reduced, providing a collegial space in which a broader range of voices are heard, but which also move the institution further from any collegial ideal and increasingly to the managerial and hierarchical. The research provides a framework for understanding the primary factors through which participants describe boundaries being expanded, maintained, or constrained, at the executive level. Three elements are identified as important, pushing against each other to shape the institution – Focus of the executive, Resilience of the institutional normative, and Channels to promote change. The research shows that none of these are fixed or dominant and are in a constant state of change, moving boundaries and changing roles and identities over time.
Imperfect Many-Body Localization in Exchange-Disordered Isotropic Spin Chains

Publisher: name: Universität Regensburg
Year: 2023
Subjects: subject: 530 Physik

description: We investigate many-body localization in isotropic Heisenberg spin chains with the local exchange parameters being subject to quenched disorder. Such systems incorporate a nonabelian symmetry in their Hamiltonian by invariance under global SU(2)-rotations. Nonabelian symmetries are predicted to hinder the emergence of a many-body localized phase even in the presence of strong disorder. We report on numerical studies using exact diagonalization for chains of common spin length 1/2 and 1. The averaged consecutive-gap ratios display a transition compatible with a crossover from an ergodic phase at small disorder strength to an incompletely localized phase at stronger disorder. Studying the sample-to-sample variance of the averaged consecutive-gap ratio, we distinguish this incompletely localized phase from the fully many-body localized phase by its scaling behavior.

description: The London penetration depth, $λ(T)$ was measured in single crystals of Ce$_{1-x}R_x$CoIn$_5$, $R$=La, Nd and Yb down to 50~mK ($T_c/T \sim$50) using a tunnel-diode resonator. In the cleanest samples $Δλ(T)$ is best described by the power law, $Δλ(T) \propto T^{n}$, with $n \sim 1$, consistent with line nodes. Substitutions of Ce with La, Nd and Yb lead to similar monotonic suppressions of $T_c$, however the effects on $Δλ(T)$ differ. While La and Nd doping results in an increase of the exponent to $n \sim 2$, as expected for a dirty nodal superconductor, Yb doping leads to $n > 3$, inconsistent with nodes, suggesting a change from nodal to nodeless superconductivity where Fermi surface topology changes were reported, implying that the nodal structure and Fermi surface topology are closely linked.

description: By using the dense coverage of the extrasolar planet survey project HATNet, we Fourier analyze 381 high-probability members of the nearby open cluster Praesepe (Beehive/M44/NGC 2632). In addition to the detection of 10 variables (of δScuti and other types), we identify 180 rotational variables (including the two known planet hosts). This sample increases the number of known rotational variables in this cluster for spectral classes earlier than M by more than a factor of three. These stars closely follow a color/magnitude -- period relation from early F to late K stars. We approximate this relation by polynomials for an easier reference to the rotational characteristics in different colors. The total (peak-to-peak) amplitudes of the large majority (94%) of these variables span the range of 0.005 to 0.04 mag. The periods cover a range from 2.5 to 15 days. These data strongly confirm that Praesepe and the Hyades have the same gyrochronological ages. Regarding the two planet hosts, Pr0211 (the one with the shorter orbital period) has a rotational period that is ~2 days shorter than the one expected from the main rotational pattern in this cluster. This, together with other examples discussed in the paper, may hint that star-planet interaction via tidal dissipation can be significant in some cases in the rotational evolution of stars hosting Hot Jupiters.

description: Coconut water was utilized to eliminate the fresh water requirement as solvent for the ingredients of the media, to add nutrients and to reduce water way pollution. Coconut water replaced distilled water at 0%, 50% and 100% in nutrient broth. Dulmage medium and Wiken and Willie medium used to grow Bacillus thruignensis var thuringensis Berliner, a microbial insecticide. The pH of the media in this first series was not adjusted. The pH of that in the second series was adjusted. Total and spore plate counts were taken. When the pH of the media was not adjusted, nutrient broth (0% coconut) produced the highest total and spore counts; Dulmage medium (0%), a far second; and Wiken and Willie medium (0%) a third. The pH of the nutrient broth and Dulmage medium (0%) a third. The pH of the nutrient broth and Dulmage medium was similar while that of Wiken and Willie medium was very low. When the pH of the media was adjusted to that of the nutrient broth (0%), Wiken and Wille medium (0%) increased in total count to out yield Dulmage medium ()%) and in spore count to outnumber nutrient broth (0%). The inclusion of coconut water at 50% and 100% levels whether the pH of the media was adjusted or not caused a reduction in both total spore counts. Aside from its effect in lowering the pH, coconut water might cause a nutrient imbalance as to affect adversely the growth of Bacillus thuringensis var thuringensis Berliner.

description: Publishing social network data for research purposes has raised serious concerns for individual privacy. There exist many privacy-preserving works that can deal with different attack models. In this paper, we introduce a novel privacy attack model and refer it as a mutual friend attack. In this model, the adversary can re-identify a pair of friends by using their number of mutual friends. To address this issue, we propose a new anonymity concept, called k-NMF anonymity, i.e., k-anonymity on the number of mutual friends, which ensures that there exist at least k-1 other friend pairs in the graph that share the same number of mutual friends. We devise algorithms to achieve the k-NMF anonymity while preserving the original vertex set in the sense that we allow the occasional addition but no deletion of vertices. Further we give an algorithm to ensure the k-degree anonymity in addition to the k-NMF anonymity. The experimental results on real-word datasets demonstrate that our approach can preserve the privacy and utility of social networks effectively against mutual friend attacks.

description: The LEPS and CLAS data of the incoherent photoproduction of $ϕ$ meson from deuteron at low energies are studied with a model for $ϕ$ meson photoproduction from nucleon consisting of Pomeron, $π$, and $η$ meson exchanges in the t-channel, and a postulated resonance, with parameters fitted to recent LEPS data on $ϕ$ production from proton near threshold. The resonance was introduced to explain an observed bump in the forward differential cross section. Within impulse approximation, we find that the Fermi motion, final state interaction, and the resonance excitation all give important contributions to improve the agreement with data. However, discrepancies remain. Contributions from $ϕ$ production via spectator nucleon by other mesons like $π, ρ,$ and $ϕ$ produced from the first nucleon need to be calculated in order to gain insight on the medium effects as well as the existence of the postulated nucleon resonance.

description: We present bounds and a closed-form high-SNR expression for the capacity of multiple-antenna systems affected by Wiener phase noise. Our results are developed for the scenario where a single oscillator drives all the radio-frequency circuitries at each transceiver (common oscillator setup), the input signal is subject to a peak-power constraint, and the channel matrix is deterministic. This scenario is relevant for line-of-sight multiple-antenna microwave backhaul links with sufficiently small antenna spacing at the transceivers. For the 2 by 2 multiple-antenna case, for a Wiener phase-noise process with standard deviation equal to 6 degrees, and at the medium/high SNR values at which microwave backhaul links operate, the upper bound reported in the paper exhibits a 3 dB gap from a lower bound obtained using 64-QAM. Furthermore, in this SNR regime the closed-form high-SNR expression is shown to be accurate.

description: We report on Hybrid-Monte-Carlo simulations of the tight-binding model with long-range Coulomb interactions for the electronic properties of graphene. We investigate the spontaneous breaking of sublattice symmetry corresponding to a transition from the semimetal to an antiferromagnetic insulating phase. Our short-range interactions thereby include the partial screening due to electrons in higher energy states from ab initio calculations based on the constrained random phase approximation [T.O.Wehling {\it et al.}, Phys.Rev.Lett.{\bf 106}, 236805 (2011)]. In contrast to a similar previous Monte-Carlo study [M.V.Ulybyshev {\it et al.}, Phys.Rev.Lett.{\bf 111}, 056801 (2013)] we also include a phenomenological model which describes the transition to the unscreened bare Coulomb interactions of graphene at half filling in the long-wavelength limit. Our results show, however, that the critical coupling for the antiferromagnetic Mott transition is largely insensitive to the strength of these long-range Coulomb tails. They hence confirm the prediction that suspended graphene remains in the semimetal phase when a realistic static screening of the Coulomb interactions is included.

description: We introduce the notion of a coherent $P$-ultrafilter on a complete ccc Boolean algebra, strenghtening the notion of a $P$-point on $ω$, and show that these ultrafilters exist generically under ${\mathfrak c} = {\mathfrak d}$. This improves the known existence result of Ketonen. Similarly, the existence theorem of Canjar can be extended to show that coherently selective ultrafilters exist generically under ${\mathfrak c} = {cov(M)}$. We use these ultrafilters in a topological application: a coherent $P$-ultrafilter on an algebra $B$ is an untouchable point in the Stone space of $B$, witnessing its nonhomogeneity.

description: Rod Abies obsega približno petdeset vrst. Večina je razširjenih v zmerno toplih območjih severne poloble (http://www.discoverlife.org), kjer imajo zelo pomembno okoljsko vlogo. Gospodarsko pomembne pa so tudi zunaj območja svoje naravne razširjenosti.  Nekatere vrste jelk so cenjena okrasna drevesa za zasaditve javnih zelenih površin. Zaradi stožčaste oblike krošnje, barve iglic in močnih vej uporabljajo vrste, ki dolgo obdržijo iglice, za proizvodnjo novoletnih jelk in vej za dekoracijo. V Evropi se v ta namen največ uporablja kavkaška jelka (Abies nordmanniana), v ZDA pa fraserjeva (Abies fraseri) in srebrna jelka (Abies procera).  Kot novoletna drevesa uporabljajo tudi balzamasto jelko (A. balsamea) in sorodno A. lasiocarpa, ter veliko jelko (A. grandis), korejsko jelko (Abies koreana), sibirsko jelko (A. sibirica), bornmullerjevo jelko (A. bornmuelleriana) in dolgoigličasto jelko (A. concolor). Srebrna jelka je tako v Evropi kot v Ameriki najpomembnejša vrsta za pridelavo vej za dekoracijo.
12M public progress report for the project "Environmental effects on physical properties of smart composites and FRP modified by carbonaceous nanofillers for structural applications"
Creators: name: Glaskova-Kuzmina, Tatjana
Publisher: name: Zenodo
Year: 2018
Subjects: Public 12M progress progress, POSTDOC-Latvia

description: Summary of 12M progress report:

During the first year of the project the main purpose was to choose, purchase and develop investigated materials: epoxy resin and at least two carbon nanofillers (nanotubes, nanofibres and/or graphene). The most promising material solution and the most optimal processing route were chosen and reported. Then two sets of epoxy and NC specimens were developed during Mobilities#2-3 to partner organization, Institute for Polymers, Composites and Biomaterials (Portici, Italy). The test specimens of epoxy and NC were subjected to environmental ageing: water absorption at 70 °C until equilibrium water content and heating at 70 °C, then freezing at ap. -20 °C to evaluate the most environmentally stable NC configuration. Based on preliminary results (without results after freezing), the most environmentally stable NC was epoxy filled with 0.1 wt. % of CNT/CNF, which had the lowest effect of temperature and moisture on thermal and electrical conductivities, along with the lowest equilibrium water content and diffusivity.
Non-relativistic particles in a thermal bath

Year: 2014

description: Heavy particles are a window to new physics and new phenomena. Since the late eighties they are treated by means of effective field theories that fully exploit the symmetries and power counting typical of non-relativistic systems. More recently these effective field theories have been extended to describe non-relativistic particles propagating in a medium. After introducing some general features common to any non-relativistic effective field theory, we discuss two specific examples: heavy Majorana neutrinos colliding in a hot plasma of Standard Model particles in the early universe and quarkonia produced in heavy-ion collisions dissociating in a quark-gluon plasma.

Extending the range of real time density matrix renormalization group simulations

description: We discuss a few simple modifications to time-dependent density matrix renormalization group (DMRG) algorithms which allow to access larger time scales. We specifically aim at beginners and present practical aspects of how to implement these modifications almost effortlessly within any standard matrix product state (MPS) based formulation of the method. Most importantly, we show how to 'combine' the Schroedinger and Heisenberg time evolutions of arbitrary pure states |psi> and operators A in the evaluation of _psi(t)=. This includes quantum quenches. The generalization (non-)thermal mixed state dynamics _rho(t)=Tr[rho A(t)] induced by an initial density matrix rho is straightforward. In the context of equilibrium (ground state or finite temperature T>0) correlation functions, one can extend the simulation time by a factor of two by 'exploiting time translation invariance', which is efficiently implementable within MPS DMRG. We present a simple analytic argument for why a recently-introduced disentangler succeeds in reducing the effort of time-dependent simulations at T>0. Finally, we advocate the python programming language as an elegant option for beginners to set up a DMRG code.
Exceptionally Long-ranged Lattice Relaxation in Oxygen-deficient Ta2O5

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The lattice relaxation in oxygen-deficient Ta2O5 is investigated using first-principles calculations. The presence of a charge-neutral oxygen vacancy can result in a long-ranged lattice relaxation which extends beyond 18 Å from the vacancy site. The lattice relaxation has significant effects on the vacancy formation energy as well as the electronic structures. The long-ranged behavior of the lattice relaxation is explained in terms of the Hellmann-Feynman forces and the potential energy surface related to the variation of Ta-O bond lengths.

PLUMED-GUI: an environment for the interactive development of molecular dynamics analysis and biasing scripts

description: PLUMED-GUI is an interactive environment to develop and test complex PLUMED scripts within the Visual Molecular Dynamics (VMD) environment. Computational biophysicists can take advantage of both PLUMED's rich syntax to define collective variables (CVs) and VMD's chemically-aware atom selection language, while working within a natural point-and-click interface. Pre-defined templates and syntax mnemonics facilitate the definition of well-known reaction coordinates. Complex CVs, e.g. involving reference snapshots used for RMSD or native contacts calculations, can be built through dialogs that provide a synoptic view of the available options. Scripts can be either exported for use in simulation programs, or evaluated on the currently loaded molecular trajectories. Development of scripts takes place without leaving VMD, thus enabling an incremental try-see-modify development model for molecular metrics.
Two-zero Majorana textures in the light of the Planck results

description: The recent results of the Planck experiment put a stringent constraint on the sum of the light neutrino masses, m1+m2+m3 < 0.23 eV (95 % CL). On the other hand, two-zero Majorana mass matrix textures predict strong correlations among the atmospheric angle and the sum of the masses. We use the Planck result to show that, for the normal hierarchy case, the texture with vanishing (2,2) and (3,3) elements is ruled out at a high confidence level; in addition, we emphasize that a future measurement of the octant of the atmospheric mixing angle (or the one sigma determination of it based on recent fit to neutrino data) will put severe constraint on the possible structure of the Majorana mass matrix. The implication of the above mentioned correlations for neutrinoless double beta-decay are also discussed, for both normal and inverted orderings.

description: Coordinate measuring machines (CMMs) are widely used to check dimensions of manufactured parts, especially in automotive industry. The major obstacles in automation of these measurements are fixturing and clamping assemblies, which are required in order to position the measured object within the CMM. This paper describes how an industrial robot can be used to manipulate the measured object within the CMM work space, in order to enable automation of complex geometry measurement.

description: The thermal experiments to be carried out onboard LISA Pathfinder (LPF) will provide essential information of the dependences of the instrument with respect to temperature variations. These thermal experiments must be modelled and simulated both to be validated for mission operations purposes and also to develop a data analysis tool able to characterise the temperature noise contribution to the instrument performance. Here we will present the models developed and the simulated signals for some of the experiments together with the corresponding interferometer readouts, the latter being computed by combining the thermal models with the global LTP (LISA Technology Package) simulator of the LTP Data Analysis team.

Local Decoherence-free Macroscopic Quantum states

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)

description: We identify a class of quantum states, each consisting of a microscopic and a macroscopic section, that are effectively decoherence-free when each particle is locally passed through a quantum channel. In particular, and in contrast to other macroscopic quantum states like the Greenberger-Horne-Zeilinger state, the content of entanglement and other quantum correlations in the microscopic to macroscopic partition of this class of states is independent of the number of particles in their macroscopic sectors, when all the particles suffer passage through local amplitude and phase damping channels. Decay of quantum correlations -- entanglement as well as quantum discord -- of this class of states in the microscopic to macroscopic partition is also much lower in the case of all the local quantum channels, as compared to the other macroscopic superposition states. The macroscopic sections of the states are formed, in each case, by using a Dicke state and an orthogonal product state, which are macroscopically distinct in terms of markedly different amounts of violation of Bell inequality.

Fungal Contamination of Some Well Water in Parts of Edo State
Creators: name: Ifeoma Enweani
Publisher: name: figshare
Year: 2020
Subjects: subject: 60599 Microbiology not elsewhere classified
subject: FOS: Biological sciences

description: Studies on the fungal contamination of some well water in Ekpoma and its environs in Edo state were carried in order to ascertain the different types of fungi found in water bodies. The result revealed that both potentially poisonous and non poisonous species of fungi were present in these wells. The poisonous species isolated include Aspergillus, Penicillum, Trichosporon, Mucor and Fusarium. The Pythium and Achyla species isolated are not of medical significance. The significance of the entire results to public health is therefore incontestable since the inhabitants are now aware that proper treatment of such water is a matter of necessity

description: This paper considers nonlinear dynamics of polarization oscillations when some materials when they are subjected to the action of an electromagnetic wave modeled by multifrequency forced Duffing equation. Multiresonance and chaotic behavior are analysed. For analysis of the case of resonance, the method of multiple scales is used and it has been found from the equation of the amplitudes for each of the possible resonance system. Possible resonances are inter alia the resonances or sub superharmonic, the primary resonance and other resonances called secondary. The phenomena of amplitude jump and hysteresis for polarization were observed and analyzed. Finally, the study of chaotic behavior for polarization was made by numerical simulation using the Runge- Kutta fourth order.
