Publisher: name: tourismos
Year: 2011

description: For years second home tourism has been an issue of discussion between tourist experts, real estate agents and politicians in both Mediterranean countries and Alpine destinations, however it has not raised much concern in academic circles. The aim of this paper is to analyze the second home phenomenon in order to acquire a better understanding of the overall situation and give an insight into the aspects and needs for policy planning. For this purpose South Tyrol has been taken as a case study, and a comprehensive overview of the situation has been determined through both quantitative and qualitative investigation on opinions and attitudes of second home owners, local residents, politicians, real estate agents. The outcome of this paper is a holistic picture of the phenomenon, which examines the positive and negative impacts and shows the need for public regulation through land use planning.

description: We explore the low-l likelihood of the angular spectrum C(l) of masked CMB temperature maps using an adaptive importance sampler. We find that, in spite of a partial sky coverage, the likelihood distribution of each C(l) closely follows an inverse gamma distribution. Our exploration is accurate enough to measure the inverse gamma parameters along with the correlation between multipoles. Those quantities are used to build an approximation of the joint posterior distribution of the low-l likelihood. The accuracy of the proposed approximation is established using both statistical criteria and a mock cosmological parameter fit. When applied to the WMAP5 data set, this approximation yields cosmological parameter estimates at the same level of accuracy as the best current techniques but with very significant speed gains.

title: Seed and Cone Insects Associated with Pinus Monophylla Torr. and Frem.
Creators: name: Jenkins, Michael James
Publisher: name: Utah State University
Year: 1977

description: Dissection and rearing studies of second-year cones disclosed six species of insects associated with the seeds and cones of singleleaf pinyon pine. Those most commonly encountered were: Dioryctria sp. probably albovittella Hulst, Conophthorus monophyllae Hopkins and Pineus coloradensis Gillette. The three remaining species were of lesser importance. These included the gall midge, Asynapta sp., a minor cone pest and two parasites, one of C. monophyllae, Acerocephala atroviolacea Crawford and an unidentified parasite of Dioryctria, of the family Ichneumonidae.
D. sp. probably albovittella was regarded as the major insect destroying cones and seeds of P. monophylla in this study. During the 1976 growing season it attained a maximum level of 29 percent infestation. C. monophyllae occurred less frequently in this study, but probably has a higher potential for destruction in years of poor cone crops or high cone beetle populations. P. coloradensis caused negligible damage to seeds and cones, but was encountered frequently. Early in the growing season it infested a maximum of 38 percent of the cones.
NEW TOURISM IN A NEW SOCIETY ARISES FROM “PEAK OIL”

Publisher: name: tourismos
Year: 2011

description: Mass international tourism has thrived on the abundant and cheap supply of energy, and this may be about to change as the world moves towards “Peak Oil”. The resultant scarcity and high price of all energy fuels will produce changes in human activities across the board, and specifically in tourism. In this looming transitional era, which has probably already arrived, tourism needs to make some dramatic changes to harmonize with the new realities of a post-energy world and its new society.

Subjects: Authentication, EEG, User-Friendly, Task-Independent.

description: Abstract

This paper introduces a cutting-edge approach to Electroencephalography (EEG) based authentication that transcends traditional task-specific requirements, significantly enhancing user experience and authentication accuracy. By employing a convolutional neural network (CNN) to develop a deep learning model, the study successfully extracts feature vectors from EEG signals without necessitating predefined tasks, offering a more adaptable and user-friendly alternative. The proposed system achieved a notable accuracy rate through experiments, including Single-Task and Multi-Task Feature Extraction methods.  The study model achieved an accuracy rate of 95% in authentication by making enhancements to the Multi-Task methodology. These experimental insights underscore the viability and efficiency of task-independent EEG authentication while maintaining robust security measures.
Gauge-invariant post-Newtonian perturbations in symmetric teleparallel gravity

Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present an extension to the gauge-invariant formulation of the parameterized post-Newtonian (PPN) formalism, which allows its application to symmetric teleparallel gravity theories. In its original formulation, the gauge-invariant PPN formalism makes use of a gauge-invariant perturbative expansion of tensor fields; however, one of the fundamental gravitational field variables in symmetric teleparallel gravity theories is a flat, torsion-free connection, hence not a tensor field. Since connections transform differently from tensor fields under diffeomorphisms, we introduce here an adapted notion of gauge-invariant perturbation variables for the symmetric teleparallel connection, and show how the lowest order terms can be expressed in terms of the common PPN potentials.

description: Objectives Sedentary behaviour (SB) is associated with increased risks of breast, colorectal, endometrial, ovarian and rectal cancers. However, the number of cancer cases attributable to SB in Germany and the associated costs are unknown.

Setting Numbers and proportions (population-attributable fractions, PAF) of new cancer cases attributable to SB with published risk estimates for Germany for the years 2024, 2030 and 2040.

Participants Sex-specific and age-specific population projections, national cancer incidence and exposure data. Primary and secondary outcome measures: new cancer cases attributable to SB and healthcare costs associated with cancer cases attributable to SB in Germany for the year 2024.

Results Estimated numbers of cancers attributable to SB are projected to be up to 7612 cases (6% of total cancer cases) in 2024, up to 7899 cases (6%) in 2030 and up to 8245 cases (6%) in 2040. The PAF attributable to SB in women is 3% for breast cancer, 8% for colon cancer, 9% for both endometrial and ovarian cancers and 2% for rectal cancer. In men, the PAF is 9% for colon cancer and 3% for rectal cancer. In 2024, the estimated costs of SB-attributable cancers are €270 million for colon cancer, €51 million for rectal cancer, €234 million for breast cancer and €242 million for female genital cancers.

Conclusions A considerable number of cancer cases can be attributed to SB, which also imposes a large health economic burden. Implementing effective prevention measures, such as workplace, school or commuting interventions, is needed to reduce the incidence of cancer attributable to this modifiable risk factor.
title: Fuel Load and Plant Community Dynamics of Bryce Canyon National Park
Creators: name: Wight, Doug W.
Publisher: name: Utah State University
Year: 1994

description: A comprehensive fuel load assessment of all plant communities in Bryce Canyon National Park is provided. Fuel loads by community type are pooled into "fuel type associations" based on similarity in predicted fire behavior, and the fuel type associations are mapped throughout the Park. For each fuel type association, a series of fire behavior simulations is presented describing expected rates of spread and intensities for typical conditions in each month of the fire season and for a worst-case scenario. These fire behavior predictions provide guidelines for writing prescribed burning prescriptions or for quickly assessing the need for possible fire suppression and the amount of effort required to suppress particular fires.

A phase-plane analysis shows that the phantom-dominated scaling solution is the stable late-time attractor of this type of models. We find that during the evolution of the universe, the equation of state $w$ changes from $w > -1$ to $w

title: Production and Biocompatibility of Spider Silk Proteins in Goat Milk
Creators: name: Decker, Richard E.
Publisher: name: Utah State University
Year: 2018

description: Due to its strength, flexibility, and biocompatibility, spider silk is a highly appealing material for applications in the medical field. Unfortunately, natural spider silk is difficult to obtain in large quantities because spiders are territorial and cannibalistic, making them impractical to farm. Synthetic spider silk proteins produced by transgenic hosts such as bacteria and goats have made it possible to obtain the quantities of spider silk needed to study it more fully and to investigate its potential uses. The spider silk proteins produced in our laboratory do not have an optimal purification method to remove all of the non-biocompatible contaminants and have not previously been tested for their biocompatibility. The first focus of this dissertation was to create goat cells that can be used to create new goats. These new goats will produce proteins that can be purified more efficiently and more completely. The second focus of this dissertation was to perform biocompatibility tests on goat-derived spider silk proteins. Prior to performing any biocompatibility tests, a method was established for removing endotoxins – an impurity that causes an immune response in the body – from the proteins. This work has shed light on areas for improvement in the silk protein purification process and laid groundwork for the production of new goat-derived proteins. These steps will help make it possible for synthetic spider silk to progress further toward becoming a viable biomaterial.
Comment on "A glance beyond the quantum model" [arXiv:0907.0372]

Year: 2010

subject: FOS: Physical sciences

description: The aim of "A glance beyond the quantum model" [arXiv:0907.0372] to modernize the Correspondence Principle is compromised by an assumption that a classical model must start with the idea of particles, whereas in empirical terms particles are secondary to events. The discussion also proposes, contradictorily, that observers who wish to model the macroscopic world classically should do so in terms of classical fields, whereas, if we are to use fields, it would more appropriate to adopt the mathematics of random fields. Finally, the formalism used for discussion of Bell inequalities introduces two assumptions that are not necessary for a random field model, locality of initial conditions and non-contextuality, even though these assumptions are, in contrast, very natural for a classical particle model. Whether we discuss physics in terms of particles or in terms of events and (random) fields leads to differences that a glance would be well to notice.

An analysis of factors influencing railway freight rates
Creators: name: Shepherdson, Stephen Dwight
Publisher: name: University of British Columbia
Year: 2010

description: The level of any particular railway freight rate is a function of the interaction between cost and demand factors for the movement of the commodity from one location to another. The purpose of this thesis is to analyse cost and demand factors influencing railway freight rates. The study focuses on three areas: 1) the determination of the joint effect of a number of factors on the rate; 2) three rate issues; and 3) the strength and weaknesses of the CTC Waybill Analysis to explain trends in rates. The analysis ranges in scope from a description of cost and demand factors affecting rates to a statistical analysis. The subjective nature of rate-making, the polarized views concerning cost- or demand- based pricing, and the impact of public policy on rate-making are discussed in Chapter 2. The theoretical relationship between a factor and the rate is described for a large number of factors in this chapter as well. The third chapter describes six rate categories. Two of these rate categories are mode-competitive rates and one is based upon specific market competitive factors. Temporal changes in these rate categories are noted in an attempt to explain the relative importance of cost and demand factors over time. In the fourth chapter the available data are examined and two rate models are postulated. These rate models are used to assess some of the issues concerning rates. Chapter 5 presents the statistical results of the study. From these results, a proposal is made for explaining trends in rates by monitoring changes in identified, significant factors over time. The study concludes that the joint effect of a number of factors is important in defining the level of a rate. All factors are not equally important and the significant factors vary for different regional movements. The results of this study indicate that both cost and demand factors are significant for explaining differences in rates. Cost factors are more significant than demand factors in all movement models examined. The value of the commodity is significant in some cases, but intermodal competition and market competition are also significant. The study concludes that the Waybill Analysis data are useful for making a detailed analysis of factors influencing rates. The analysis of a number of factors is considered to be a superior method to that of examining one aggregate measure, average revenue per ton-mile, for explaining trends in rates.

description: Cosmology with Type Ia supernovae heretofore has required extensive spectroscopic follow-up to establish a redshift. Though tolerable at the present discovery rate, the next generation of ground-based all-sky survey instruments will render this approach unsustainable. Photometry-based redshift determination is a viable alternative, but introduces non-negligible errors that ultimately degrade the ability to discriminate between competing cosmologies. We present a strictly template-based photometric redshift estimator and compute redshift reconstruction errors in the presence of photometry and statistical errors. With reasonable assumptions for a cadence and supernovae distribution, these redshift errors are combined with systematic errors and propagated using the Fisher matrix formalism to derive lower bounds on the joint errors in $Ω_w$ and $Ω_w'$ relevant to the next generation of ground-based all-sky survey.

Creators: name: Blythe, Todd L.
Publisher: name: Utah State University
Year: 2018

description: In 1899, Robert T. Hill led the first scientific exploration of the remote segment of the Rio Grande known as the Big Bend. Hill’s observations from this expedition were published in an article titled “Running the Cañons of the Rio Grande.” At the time of Hill’s expedition, the stream flow of the Rio Grande was largely depleted by water development in the upstream portions of the basin. The continued overallocation of the Rio Grande has led to the degradation of aquatic ecosystems in the Big Bend, one of North America’s largest transboundary protected areas, such that management of natural resources in this region is a high priority. Many of the native species in this region are listed as threatened or endangered due to habitat loss, which is driven by channel narrowing. Thus, excess fine sediment, along with invasive riparian species, has been identified as negatively impacting ecological resources in the Big Bend and studies recommend increased stream flow as the most effective tool for managing excess fine sediment. Aside from historical accounts, there was previously no estimate of the Rio Grande’s natural flow regime nor an adequate understanding of how the role of characteristic floods in the Big Bend shaped the pre-disturbance channel. In the following two studies, we fill in these crucial knowledge gaps by estimating the pre-disturbance flow regime of the Rio Grande, describing how channel narrowing is not spatially uniform in the Big Bend, and analyzing past floods to determine the role of past flood regimes in shaping alluvial deposits that contribute to channel narrowing.

The formalism gives rise to Berry effect terms in the equations of motion, manifested as the Rytov polarization rotation law and the polarization-dependent Hall effect. We show that the formalism is also applicable to the case of non-periodic inhomogeneous media, yielding explicit expressions for the Berry effect terms.

description: Abstract

This research examines the perspectives of final-year business students in the UAE regarding their preparedness for the labor market, with a focus on the key skills and learning approaches they consider essential for employability. Through an exploratory descriptive research approach, the study surveyed 156 students across two universities, focusing on their readiness to enter the UAE labor market. The findings indicate that communication, adaptability, and learning skills are deemed the most critical employability skills, with significant differences noted across departments. Students expressed confidence in their academic skills, particularly discipline competency, yet identified IT literacy as an area needing improvement. Experiential learning methods, such as internships and industry placements, were rated as the most effective for acquiring employability skills, surpassing traditional lecture-based approaches. The study highlights the need for UAE universities to align curricula with industry demands and emphasize practical, hands-on learning to ensure graduates are well-prepared for the evolving job market.

Creators: name: White, Connor J.
Publisher: name: Utah State University
Year: 2018

description: This study focused on using a mapping tool, Space Syntax, to analyze the connectivity of the Cache County road network and its use to plan for bicycles. Space Syntax is being compared to another method that is already used by city planners called Bicycle Level of Service, or BLOS. The two analyses used data from Cache County and, after they were modeled and evaluated, a statistical analysis was done to see how similar one is to the other. The analyses were done at both a regional and a local scale. At both scales the analyses were not similar.
Data was added to the Space Syntax analysis at both scales to see if it would influence making it more similar to BLOS. Adding the data had no effect in making them similar. It was determined that Space Syntax and BLOS are not similar and more research would need to be done to attempt to make them similar. They both have advantages and disadvantages to them when being used for planning for bicycles. One is not necessarily better than the other, as they are two different methods that could be used.

description: Nonadiabatic holonomic quantum transformations (NHQTs) have attracted wide attention and have been applied in many aspects of quantum computation, whereas related research is usually limited to the field of quantum physics. Here we bring NHQTs into constructing a unidirectional acoustic metamaterial (UDAM) for shaping classical beams. The UDAM is made up of an array of three-waveguide couplers, where the propagation of acoustic waves mimics the evolution of NHQTs. The excellent agreement among analytical predictions, numerical simulations, and experimental measurements confirms the great applicability of NHQTs in acoustic metamaterial engineering. The present work extends research on NHQTs from quantum physics to the field of classical waves for designing metamaterials with simple structures and may pave a new way to design UDAMs that would be of potential applications in acoustic isolation, communication, and stealth.

Creators: name: Tobler, Emily
Publisher: name: Utah State University
Year: 2018

description: Like any other agricultural industry, many different career paths in the equine field are becoming more technologically advanced. To adapt to technological progress, current standards need to be integrated into school-based agricultural education courses to properly train and teach students about current industry standards. In addition to equine science curriculum development, emphasis must also be focused on providing assistance to secondary-school-based agriculture teachers so they can effectively teach industry-based equine science objectives in their programs.
The equine curriculum objectives were measured in terms of perceived importance by equine professionals and post-secondary equine educators as well as Arizona school-based agriculture teachers. Further, the Arizona school-based agriculture teachers indicated their self-perceived ability to teach the objectives. Demographics for each group (equine industry professionals and Arizona school-based agriculture teachers) were also collected. A Borich needs assessment was calculated to prioritize areas needed for professional development of school-based agriculture teachers.
Recommendations include the importance of bringing secondary-school-based agricultural education equine science curricula in line with industry standards. Further, providing professional development to secondary-school-based agriculture teachers is key to increasing teachers’ competence and ability to teach industry-based equine science.
Electrostatic forces above graphene nanoribbons and edges interpreted as partly hydrogen-free

description: Graphene nanoribbons' electronic transport properties strongly depend on the type of edge, armchair, zigzag or other, and on edge functionalization that can be used for band-gap engineering. For only partly hydrogenated edges interesting magnetic properties are predicted. Electric charge accumulates at edges and corners. Scanning force microscopy has so far shown the centre of graphene nanoribbons with atomic resolution using a quartz crystal tuning fork sensor of high stiffness. Weak long-range electrostatic forces related to the charge accumulation on the edges of graphene nanoribbons could not be imaged so far. Here, we show the electrostatic forces at the corners and edges of graphene nanoribbons are amenable to measurement. We use soft cantilevers and a bimodal imaging technique to combine enhanced sensitivity to weak long-range electrostatic forces with the high resolution of the second-frequency shift. Additionally, in our work the edges of the nanoribbons are mainly hydrogen-free, opening to the route to investigations of partly hydrogenated magnetic nanoribbons.

description: This PhD thesis describes set up of technological models for obtaining high health value
foods and ingredients that preserve the final product characteristics as well as enrich with
nutritional components.
In particular, the main object of my research has been Virgin Olive Oil (VOO) and its
important antioxidant compounds which differentiate it from all other vegetables oils.
It is well known how the qualitative and quantitative presence of phenolic molecules
extracted from olives during oil production is fundamental for its oxidative and nutritional
quality. For this purpose, agronomic and technological conditions of its production have
been investigated. It has also been examined how this fraction can be better preserved
during storage. Moreover, its relation with VOO sensorial characteristics and its interaction
with a protein in emulsion foods have also been studied.
Finally, an experimental work was carried out to determine the antioxidative and heat
resistance properties of a new antioxidant (EVS-OL) when used for high temperature frying
such as is typically employed for the preparation of french fries.
Results of the scientific research have been submitted for a publication and some data has
already been published in national and international scientific journals.
NAUTICAL TOURISM IN FOSTERING THE SUSTAINABLE DEVELOPMENT: A CASE STUDY OF CROATIA’S COAST AND ISLAND

description: This paper presents a systematic and comprehensive analysis of the economic, social and environmental aspects of developing nautical tourism. It examines the problems of sitting and selecting the location of a nautical port, and it identifies economic and political, and socio-cultural factors. The paper brings out the importance of balanced development of a port of nautical tourism as a primary determinant of the integrated management of the marine domain. Due to its manifold multiplier effects, nautical tourism is a major branch of tourism that has great potential for development in Croatia. The paper points out the importance of systematically valorising the potential of nautical tourism on the principles of sustainable development, while encouraging and raising the nautical-tourism offering to a higher level. It underlines the need to enlarge the capacities of nautical-tourism ports, especially on Croatia’s islands, thus helping to increase the standard of living of coastal residents. In doing so, the development process must take into account the principles of spatial organisation and the needs of people living and working within the territory of a nautical-tourism destination.

We prove, with a renormalization group approach, that the vector and axial Ward identities are broken by the Adler-Bell-Jackiw anomaly; and we rigorously establish three widely believed consequences: a) the interacting meson-meson correlation equals a free boson propagator, though the mass is additively renormalized by the anomaly; b) the anomaly is quadratic in the charge, in agreement with the Adler-Bardeen formula; c) the fermion-fermion correlation has an anomalous long-distance decay.

description: Abstract

The demand for high quality alloyed joints in aviation, automotive and power generative domain have led to the evolution of plasma arc welding process. In fact, nickel based super alloys is one such element that serves the purpose due to its extraordinary combination of high strength, oxidation and corrosion resistant properties even at extreme service conditions. However, fusion welding of Inconel 718 alloy is often associated with solidification cracking and fissure formation which challenges its weldability. Therefore, the present work is focused on presenting a detailed investigation on the influence of processing conditions on weld quality characteristics of Inconel 718 alloy. The design of experiments is framed such that the gas flow rate, welding speed along with current is varied for a constant arc voltage during plasma arc welding of Inconel 718 alloy. The processing conditions are varied in order to evaluate the macro and microstructural features along with micro-hardness attribute. Based on macro microstructural features and hardness attribute it can be assessed that plasma welding have immense potential to weld Inconel alloy without generating any major defects such as spatter, cracks, gas holes or porosity and it can be recommended for industrial application.

description: In this letter we compute the leading chiral corrections to the ratio between the tensor and the vector decay couplings for the lowest lying vector meson multiplet (rho, K^*, phi). We show that the leading chiral logarithms arise from tadpole contributions and are therefore entirely fixed by chiral symmetry, while the next to leading corrections are purely analytic. Interestingly, the flavour structure of the chiral logarithms implies that only the rho meson is sensitive to pion logarithms. By examining SU(2)_L\times SU(2)_R\times U(1)_S theories we show that this result can be easily understood and that it holds to all orders in the m_s expansion. Recent lattice data seem to comply with our results.

title: The Abiotic and Biotic Controls of Arctic Lake Food Webs: A Multifaceted Approach to Quantifying Trophic Structure and Function

description: The Arctic is warming faster than any other region of the globe. To conserve and manage many thousands of lakes across arctic landscapes, scientists need to understand historic and present conditions within these lakes to predict how the lakes, and the organisms that inhabit them, may respond to a changing climate. The goal of my research was to improve our understanding of what physical, chemical, and biological factors contribute to: 1) how lake food webs are assembled; and, 2) how these food webs may change in the future. First, I used long-term observations and lab experiments to determine how fish food, including zooplankton and snails, may respond to a warming climate. I then used field measurements of arctic char (Salvelinus alpinus) body characteristics, genetic samples, and fish diets to investigate if, and potentially why, populations of arctic char across a series of lakes achieve different maximum body sizes. Finally, as a method of monitoring population-level changes of fish abundance, I collected samples of arctic char DNA in lake water to test if estimated arctic char population abundances within a given lake correspond to the amount of DNA collected.
Fish will require more food to eat as their metabolism increases with warming lake temperatures. Based on a thirty-year period of record, I determined zooplankton abundance increases in warmer years, indicating there is likely to be enough food for fishes in the future. Accordingly, zooplankton and snail abundance and development was also faster in warmer treatments of my lab experiments. My field observations indicated these are important prey items for arctic char. Small arctic char eat more zooplankton and large arctic char eat more snails, and these observations were consistent whether or not other predators are found in the particular lake. Similarly, my analyses did not indicate morphological or genetic differences between small and large arctic char within the same lake, suggesting arctic char size structure is determine by biological characteristics, including primary productivity and arctic char density. Indeed, estimates of arctic char population abundances across a series of lakes followed a gradient of arctic char densities, and my DNA sampling corresponded with this gradient.
As there are thousands of lakes across the Arctic, my research demonstrates lake food webs, and the fishes within them, are likely to adapt to a warming climate. However, biological, chemical, and physical properties of these lakes can vary widely such that management and conservation plans may need to be developed at relatively small spatial scales across a large landscape.

description: Tourism researchers have begun to study the phenomenon of domestic tourism, especially in developing countries. The growth of research interest in domestic tourism in developing countries underpins a stream of research in developed countries. The analysis reveals the appeal of these distinctive forms of tourism, international and domestic with regards to leisure, recreation and tourism patterns, but also highlights potential limitations including the dilemma of how to deal with the question of environmental quality that is affected by prevailing international and domestic tourism activities. Impacts of climate change on domestic and international tourism and environmental impacts caused by domestic and international tourism are highlighted. This paper suggests that Environmental Education is the key to this critical area concerning domestic tourism, international globalized tourism and environmental impacts.

description: Chiral photonics opens new pathways to manipulate light-matter interactions and tailor the optical response of meta-surfaces and -materials by nanostructuring nontrivial patterns. Chirality of matter, such as that of molecules, and light, which in the simplest case is given by the handedness of circular polarization, have attracted much attention for applications in chemistry, nanophotonics and optical information processing. We report the design of chiral photonic structures using two machine learning methods, the evolutionary algorithm and neural network approach, for rapid and efficient optimization of optical properties for dielectric metasurfaces. The design recipes obtained for visible light in the range of transition-metal dichalcogenide exciton resonances show a frequency-dependent modification in the reflected light's degree of circular polarization, that is represented by the difference between left- and right-circularly polarized intensity. Our results suggest the facile fabrication and characterization of optical nanopatterned reflectors for chirality-sensitive light-matter coupling scenarios employing tungsten disulfide as possible active material with features such as valley Hall effect and optical valley coherence.
Le vie del commento: le osservazioni muratoriane alle rime del Petrarca

description: Nella ricerca condotta sulle Osservazioni muratoriane alle Rime petrarchesche, si è
tentato di mettere in luce la ‘scienza del commento’, ad esse sottesa, cui
contribuivano gli snodi teorici, l’accertamento filologico, le strategie
argomentative, i debiti esegetici. Tra difesa e riforma della poesia, il commento
muratoriano si pone infatti, in piena età arcadica, al vertice della coniunctio tra
esigenza conoscitiva e visione morale. Il «buon cammino» del Muratori, passando
per le vie del Petrarca, sanciva di fatto una superiore giurisdizione letteraria, a cui
rimettere come ad un foro esterno, censure e difese: colpisce, infatti, il suo vaglio
tecnico-argomentativo delle Rime del Petrarca, valutate secondo concordanze,
rinvii a commenti storici, connessioni intertestuali, analogie contenutistiche e
stilistiche, struttura metrica, uso delle immagini di fantasia e loro mescidazione
rispetto al verosimile.
È insomma l’idea di un commento ‘ben proporzionato’, situato oltretutto in una
zona di percorrenza mista, tra riuso e canonizzazione (come dimostra la sua
ricezione nelle storiografie letterarie della seconda metà del XVIII secolo), diviso
tra attenzione all’usus scribendi dell’autore e appelli collaborativi al lettore, quello
che, grazie al Muratori, in piena età arcadica, riporterà al centro il petrarchismo: un
petrarchismo potenziato, promosso ad insegnamento attivo e a sistema storicocritico
che il buon gusto ridisegnava secondo nuove coperture normative ed
esigenze metodologiche, ordinandolo, secondo uno stilema tipico della riflessione
filosofico-religiosa muratoriana, ad una ‘regolata lettura’.

description: We numerically study a one dimensional, nonlinear lattice model which in the linear limit is relevant to the study of bending (flexural) waves. In contrast with the classic one dimensional mass-spring system, the linear dispersion relation of the considered model has different characteristics in the low frequency limit. By introducing disorder in the masses of the lattice particles, we investigate how different nonlinearities (cubic, quartic and their combination) lead to energy delocalization, equipartition and chaotic dynamics. We excite the lattice using single site initial momentum excitations corresponding to a strongly localized linear mode and increase the initial energy of excitation. Beyond a certain energy threshold, when the cubic nonlinearity is present, the system is found to reach energy equipartition and total delocalization. On the other hand, when only the quartic nonlinearity is activated, the system remains localized and away from equipartition at least for the energies and evolution times considered here. However, for large enough energies for all types of nonlinearities we observe chaos. This chaotic behavior is combined with energy delocalization when cubic nonlinearities are present, while the appearance of only quartic nonlinearity leads to energy localization. Our results reveal a rich dynamical behavior and show differences with the relevant Fermi-Pasta-Ulam-Tsingou model. Our findings pave the way for the study of models relevant to bending (flexural) waves in the presence of nonlinearity and disorder, anticipating different energy transport behaviors.
