Creators: name: Henriques, Cláudia Helena Nunes
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2012

description: O artigo visa refletir sobre a relação cada vez mais estreita entre cultura e economia e nomeadamente entre património (tangível e intangível) e turismo cultural/criativo, associado a um dado território. Com esta intenção, apoia-se na Viagem Filosófica de Alexandre Rodrigues Ferreira à Amazónia, no século XVIII, bem como na multiplicidade de documentos de diferentes tipos a ela associados, de modo a evidenciar em que medida este património pode contextualizar-se no âmbito da conceção, divulgação e promoção de percursos/itinerários/rotas turísticoculturais sustentáveis, valorizadores da identidade luso-brasileira.

Turismo Urbano e Análise Configuracional – O caso da cidade de Silves (Algarve)
Creators: name: Pereira, António José Raiado
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2012

description: O turismo urbano pode beneficiar muito das modernas técnicas de análise configuracional porque estas permitem prever os fluxos naturais do movimento humano, com base na análise quantitativa da forma particular que o espaço público urbano assume na malha urbana disponível, e daí reescrever a acessibilidade dos recursos urbanos que se pretendem oferecer aos visitantes. Conceptualmente, o modelo sublinha a relação entre o ambiente urbano, o cityscape, e o comportamento humano. Neste estudo apresenta-se, resumidamente, uma dessas técnicas de análise configuracional, o modelo sintático ou Space Syntax, e como ela foi usada para incrementar o turismo urbano, ao ajudar no desenho de uma estratégia para captar e conduzir visitantes ao centro da cidade de Silves, de entre os muitos milhares que visitam anualmente o seu Castelo, localizado em área periférica e segregada.

description: In this article an introduction to the thermal field theory within imaginary time has been discussed in details. The imaginary time formalism has been introduced through both the operatorial and the functional integration method. The prescription to perform frequency sum for boson and fermion has been discussed. Green's function both in Minkowski time as well as in Euclidean time has been derived. The tadpole diagram in $ϕ^4$ theory and the self-energy in $ϕ^3$ theory have been computed. The basic features of general two point functions for both fermions and bosons in presence of a heat bath have been discussed. Then the free partition functions for scalar, fermion and gauge field, and interacting scalar field have been obtained. The quantum electrodynamics (QED) and gauge fixing have been discussed in details. The one-loop self-energy for electron and photon in QED have been obtained in hard thermal loop (HTL) approximation. The dispersion properties and collective excitations of both electron and photon in a thermal medium have been presented. The spectral representation of fermion and gauge boson propagators have been obtained. In HTL approximation, the generalisation of QED results of two point functions to quantum chromodynamics (QCD) have been outlined that mostly involve group theoretical factors. As an effective field theory approach the HTL resummation and the HTL perturbation theory have been introduced. The leading order, next-to-leading order and next-to-next-leading order free energy and pressure for deconfined QCD medium created in heavy-ion collisions have been computed within HTLpt. The general features of the deconfined QCD medium have also been outlined with non-perturbative effects like gluon condensate and Gribov-Zwanziger action. The dilepton production rates from quark-gluon plasma with these non-perturbative effects have been computed.

description: O envolvimento da comunidade no processo de revitalização do turismo na Ilha tem como vetor principal a proposta de reunificação municipal. Assim, Vera Cruz e Itaparica se tornariam um único município e, portanto, um único “produto turístico” beneficiando-se da imagem da Ilha como um único destino. Embora esta não seja a única alternativa possível de ampliar a atividade turística na Ilha, este tem sido um dos principais movimentos, senão o único, na tentativa de resgate da atratividade ilhéu.

A Heuristic Approach to the Far-Future State of a Universe Dominated by Phantom Energy
Creators: name: Kalntis, Nikolaos
Publisher: name: arXiv
Year: 2022
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This work is based on a cosmological scenario of a universe dominated by phantom energy with equation of state parameter $w<-1$ and the analysis of its asymptotic behaviour in the far-future. The author discusses whether a Big Rip singularity could be reached in the future. Working in the context of general relativity, it is argued that the Big Rip singularity could be avoided due to the gravitational Schwinger pair-production, even if no other particle-creating contribution takes place. In this model, the universe is described in its far-future by a state of a constant but large Hubble rate and energy density, as well as of a constant but low horizon entropy. Similar conditions existed at the beginning of the universe. Therefore, according to this analysis, not only the Big Rip singularity could be avoided in the far-future but also the universe could asymptotically be led to a new inflationary phase, after which more and more universes could be created.

description: Ground states are a well-known class of Hadamard states in smooth spacetimes. In this paper we show that the ground state of the Klein-Gordon field in a non-smooth ultrastatic spacetime is an adiabatic state. The order of the state depends linearly on the regularity of the metric. We obtain the result by combining microlocal estimates for the causal propagator, propagation of singularities results for non-smooth pseudodifferential operators, and eigenvalue asymptotics for elliptic operators of low regularity.

description: As posições antagónicas existentes entre o crescimento imobiliário-turístico e a conservação do património territorial são muito propícias ao desenvolvimento de conflitos, não estando o sistema de planeamento territorial vigente no país preparado para gerir esses conflitos. Uma visão abrangente das causas desses conflitos, que incida no conhecimento não só dos interesses específicos dos atores, mas também dos fatores que contribuem para a escalada do conflito, é fundamental para definir uma estratégia adequada para a sua gestão e para reconhecer as limitações estruturais que lhe estarão associadas. É exatamente sobre a sistematização das várias fontes dos conflitos que ocorrem entre o turismo e o ordenamento do território em Portugal que a presente comunicação se centra. Para este efeito, entrevistaram-se 26 atores públicos e privados responsáveis por políticas e intervenções com impacte num território sujeito a uma forte pressão imobiliário-turística e que detém, simultaneamente, um elevado valor natural: o litoral Troia/ Melides. Conclui-se que se não existir uma mudança estrutural ao nível de algumas políticas públicas, da organização institucional e ainda dos processos de harmonização de interesses, será muito difícil gerir de uma forma colaborativa os conflitos que existem entre turismo e território, tendo em vista a sua superação.

description: Photoplethysmography (PPG) signal comprises physiological information related to cardiorespiratory health. However, while recording, these PPG signals are easily corrupted by motion artifacts and body movements, leading to noise enriched, poor quality signals. Therefore ensuring high-quality signals is necessary to extract cardiorespiratory information accurately. Although there exists several rule-based and Machine-Learning (ML) - based approaches for PPG signal quality estimation, those algorithms' efficacy is questionable. Thus, this work proposes a lightweight CNN architecture for signal quality assessment employing a novel Quantum pattern recognition (QPR) technique. The proposed algorithm is validated on manually annotated data obtained from the University of Queensland database. A total of 28366, 5s signal segments are preprocessed and transformed into image files of 20 x 500 pixels. The image files are treated as an input to the 2D CNN architecture. The developed model classifies the PPG signal as `good' or `bad' with an accuracy of 98.3% with 99.3% sensitivity, 94.5% specificity and 98.9% F1-score. Finally, the performance of the proposed framework is validated against the noisy `Welltory app' collected PPG database. Even in a noisy environment, the proposed architecture proved its competence. Experimental analysis concludes that a slim architecture along with a novel Spatio-temporal pattern recognition technique improve the system's performance. Hence, the proposed approach can be useful to classify good and bad PPG signals for a resource-constrained wearable implementation.

description: We report the discovery of a candidate brown dwarf or a very low mass stellar companion (MARVELS-5b) to the star HIP 67526 from the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). The radial velocity curve for this object contains 31 epochs spread over 2.5 years. Our Keplerian fit using a Markov Chain Monte Carlo approach, reveals that the companion has an orbital period of $90.2695^{+0.0188}_{-0.0187}$ days, an eccentricity of $0.4375 \pm 0.0040$ and a semi-amplitude of $2948.14^{+16.65}_{-16.55}$ m s$^{-1}$. Using additional high-resolution spectroscopy, we find the host star has an effective temperature $T_{\rm{eff}}=6004 \pm 34$ K, a surface gravity $\log g$ [cgs] $=4.55 \pm 0.17$ and a metallicity [Fe/H] $=+0.04 \pm 0.06$. The stellar mass and radius determined through the empirical relationship of Torres et al. (2010), yields 1.10$\pm$0.09 $M_{\sun}$ and 0.92$\pm$0.19 $R_{\sun}$. The minimum mass of MARVELS-5b is $65.0 \pm 2.9 M_{Jup}$, indicating that it is likely to be either a brown dwarf or a very low mass star, thus occupying a relatively sparsely-populated region of the mass function of companions to solar-type stars. The distance to this system is 101$\pm$10 pc from the astrometric measurements of Hipparcos. No stellar tertiary is detected in the high-contrast images taken by either FastCam lucky imaging or Keck adaptive optics imaging, ruling out any star with mass greater than 0.2$M_{\sun}$ at a separation larger than 40 AU.

description: Features such as photon rings, jets, or hot. spots can leave particular topological signatures in a black hole image. As such, topological data analysis can be used to characterize images resulting from high resolution observations (synthetic or real) of black holes in the electromagnetic sector. We demonstrate that persistent homology allows for this characterization to be made automatically by counting the number of connected components and one-dimensional holes. Further, persistent homology also allows for the distance between connected components or diameter of holes to be extracted from the image. In order to apply persistent homology on synthetic black hole images, we also introduce metronization, a new algorithm to prepare black hole images into a form that is suitable for topological analysis.

description: Tens of Zr inter-atomic potentials (force fields) have been developed to enable atomic-scale simulations of Zr alloys. These can provide critical insight in the in-reactor behaviour of nuclear fuel cladding and structural components exposed, but the results are strongly sensitive to the choice of potential. We provide a comprehensive comparison of 13 popular Zr potentials, and assess their ability to reproduce key physical, mechanical, structural and thermodynamic properties of Zr. We assess the lattice parameters, thermal expansion, melting point, volume-energy response, allotropic phase stability, elastic properties, and point defect energies, and compare them to experimental and ab-initio values. No potential was found to outperform all others on all aspects, but for every metric considered here, at least one potential was found to provide reliable results. Older embedded-atom method (EAM) potentials tend to excel in 2-3 metrics each, but at the cost of poorer transferability. The two highest-performing potentials overall, with complementary strengths and weaknesses, were the 2021 angular-dependent potential of Smirnova and Starikov (Comp. Mater. Sci. 197, 110581) and the 2019 embedded-atom method potential of Wimmer et al (J. Nucl. Mater. 532, 152055). All potentials trained through machine learning algorithms proved to have lower overall accuracy, and less transferability, than simpler and computationally faster potentials available. Point defect structures and energies is where the greatest divergence and least accuracy is observed. We created maps that will help modellers select the most suitable potential for a specific application, and which may help identify areas of improvement in future potentials.

description: We focus on polymer-grafted nanoparticles (PGNP). A PGNP is composed of two different layers: the hard core of a nanoparticle and the soft corona of grafted polymers on the surface. It is predicted that PGNPs with these two distinct layers will have similar behaviors as star polymers and hard spheres. The interaction between PGNPs strongly depend upon their grafting density and the length of the grafted polymer chains, N. Thus, PGNP may exhibit polymorphism. Moreover, it is expected that crystals made from PGNPs will be structurally tough due to the entanglement of grafted polymers. The crystal polymorph of PGNP is explored using molecular dynamics simulations. We succeeded in finding FCC/HCP and BCC crystals depending on the length of the grafted polymer chain. When N is small, PGNPs behave like hard spheres. The crystals formed are arranged in FCC/HCP structure, much like the phase transition observed in an Alder transition. When N is large enough, the increase in the free energy of grafted polymers can no longer be neglected. Thus, the crystals formed in these systems are arranged in BCC structure, which has a lower density than FCC/HCP. When N is not too small or large, FCC/HCP structures are observed when the concentration of PGNPs is low, but a phase transition occurs when the concentration of PGNPs becomes higher with the compression of the system. Again, the increase in free energy of grafted polymers can no longer be neglected and the crystals arrange themselves in a BCC structure. Also, it can be revealed that the lattice spacing of PGNP crystals can be controlled easily and widely by the chain length. These results should play an important role in many future simulations and experimental studies of PGNP crystals.

description: Laser-driven plasma accelerators can generate accelerating gradients three orders of magnitude larger than radio-frequency accelerators and have achieved beam energies above 1 GeV in centimetre long stages. However, the pulse repetition rate and wall-plug efficiency of plasma accelerators is limited by the driving laser to less than approximately 1 Hz and 0.1% respectively. Here we investigate the prospects for exciting the plasma wave with trains of low-energy laser pulses rather than a single high-energy pulse. Resonantly exciting the wakefield in this way would enable the use of different technologies, such as fibre or thin-disc lasers, which are able to operate at multi-kilohertz pulse repetition rates and with wall-plug efficiencies two orders of magnitude higher than current laser systems. We outline the parameters of efficient, GeV-scale, 10-kHz plasma accelerators and show that they could drive compact X-ray sources with average photon fluxes comparable to those of third-generation light source but with significantly improved temporal resolution. Likewise FEL operation could be driven with comparable peak power but with significantly larger repetition rates than extant FELs.

As a particular example, we study families of conservative contact Lie systems. Liouville theorems, contact reductions, and Gromov non-squeezing theorems are developed and applied to contact Lie systems. Our results are illustrated by examples with relevant physical and mathematical applications, e.g. Schwarz equations, Brockett systems, etcetera.

description: O presente estudo tem como objetivo a aplicação de três modelos de localização de hotéis em destinos urbanos: o modelo de cidade histórico-turística de Burtenshaw, Bateman e Ashworth (Burtenshaw et al., 1981), o modelo de cidade turístico-histórica de Ashworth e Tunbridge (2000) e o modelo de hierarquia da localização de hotéis de Egan e Nield (2000). O objeto de estudo foi a hotelaria da cidade de Curitiba durante o período de 1966 a 2008. A aplicação de modelos europeus em uma cidade brasileira deve-se primeiramente à inexistência de modelos brasileiros e a busca de um modelo de localização de hotéis. Adotou-se uma abordagem metodológica empírico-analítica e revisão de literatura conceitual; os dados foram obtidos por meio de pesquisa bibliográfica e documental. Após o estudo verificou-se que houve dispersão na localização dos hotéis após a instalação das montadoras automobilísticas na região metropolitana de Curitiba após o ano de 1995, fato não ocorrido no ano de 1972 quando a Cidade Industrial de Curitiba foi inaugurada. A aplicação do modelo de cidade histórico-turística de Burtenshaw et al. (1981) foi corroborada, os hotéis ficam próximos ao centro histórico e das vias de acesso. O modelo de Ashworth e Tunbridge (2000), não se confirmou em Curitiba, sendo então detectado um modelo de cidade turístico-histórica diferente. Quanto ao modelo de hierarquia da localização de hotéis de Egan e Nield (2000), foi refutado, pois os hotéis de Curitiba não seguem uma ordem de localização. Não existe uma maior concentração de categoria de hotéis que corrobore o modelo defendido pelos autores o que evidencia a particularidade da localização da hotelaria da capital paranaense.

We extend the construction to the algebroids setting, the main example being the action Lie algebroid.

description: A {\em conflict-free coloring} of a graph {\em with respect to open} (resp., {\em closed}) {\em neighborhood} is a coloring of vertices such that for every vertex there is a color appearing exactly once in its open (resp., closed) neighborhood. Similarly, a {\em unique-maximum coloring} of a graph {\em with respect to open} (resp., {\em closed}) {\em neighborhood} is a coloring of vertices such that for every vertex the maximum color appearing in its open (resp., closed) neighborhood appears exactly once. There is a vast amount of literature on both notions where the colorings need not be proper, i.e., adjacent vertices are allowed to have the same color. In this paper, we initiate a study of both colorings in the proper settings with the focus given mainly to planar graphs. We establish upper bounds for the number of colors in the class of planar graphs for all considered colorings and provide constructions of planar graphs attaining relatively high values of the corresponding chromatic numbers. As a main result, we prove that every planar graph admits a proper unique-maximum coloring with respect to open neighborhood with at most 10 colors, and give examples of planar graphs needing at least $6$ colors for such a coloring. We also establish tight upper bounds for outerplanar graphs. Finally, we provide several new bounds also for the improper setting of considered colorings.

description: Machine Translation for Indian languages is an emerging research area. Transliteration is one such module that we design while designing a translation system. Transliteration means mapping of source language text into the target language. Simple mapping decreases the efficiency of overall translation system. We propose the use of stemming and part-of-speech tagging for transliteration. The effectiveness of translation can be improved if we use part-of-speech tagging and stemming assisted transliteration.We have shown that much of the content in Gujarati gets transliterated while being processed for translation to Hindi language.

Recently, a lower bound on the probability of finding a particle after propagating for a given time has been derived for well-defined initial constraints on position and momentum under the assumption that particles travel in straight lines. Here, we investigate this lower limit experimentally with photons. We prepared a superposition of position and momentum states by using slits, lenses and an interferometer, and observed a quantum interference between position and momentum. The lower bound was then evaluated using the initial state and the result was 5.9\% below this classical bound.

description: Using new UV magnitudes for a sample of early-type galaxies, ETGs, with published stellar mass-to-light ratios, Upsilon_*, we find a correlation between UV color and Upsilon_* that is tighter than those previously identified between Upsilon_* and either the central stellar velocity dispersion, metallicity, or alpha enhancement. The sense of the correlation is that galaxies with larger Upsilon_* are bluer in the UV. We conjecture that differences in the lower mass end of the stellar initial mass function, IMF, are related to the nature of the extreme horizontal branch populations that are generally responsible for the UV flux in ETGs. If so, then UV color can be used to identify ETGs with particular IMF properties and to estimate Upsilon_*.

description: This method plays an important role in the treatment of industrial wastewater and the separation of mineral and organic compounds in wastewater. The importance of using a mechanical method is that the wastewater from production is prepared for the next treatment steps. That is, it completely takes the process of decontamination of water using methods other than harmful factors to the final stage. Today, the treatment and recycling of wastewater from industrial enterprises by the above method increases the efficiency of water use.

description: We propose a new method for the computation of quantum three-point functions for operators in su(2) sectors of N=4 super Yang-Mills theory. The method is based on the existence of a unitary transformation relating inhomogeneous and long-range spin chains. This transformation can be traced back to a combination of boost operators and an inhomogeneous version of Baxter's corner transfer matrix. We reproduce the existing results for the one-loop structure constants in a simplified form and indicate how to use the method at higher loop orders. Then we evaluate the one-loop structure constants in the quasiclassical limit and compare them with the recent strong coupling computation.

description: The neutron and proton drip lines represent the limits of the nuclear landscape. While the proton drip line is measured experimentally up to rather high $Z$-values, the location of the neutron drip line for absolute majority of elements is based on theoretical predictions which involve extreme extrapolations. The first ever systematic investigation of the location of the proton and neutron drip lines in the covariant density functional theory has been performed by employing a set of the state-of-the-art parametrizations. Calculated theoretical uncertainties in the position of two-neutron drip line are compared with those obtained in non-relativistic DFT calculations. Shell effects drastically affect the shape of two-neutron drip line. In particular, model uncertainties in the definition of two-neutron drip line at $Z\sim 54, N=126$ and $Z\sim 82, N=184$ are very small due to the impact of spherical shell closures at N=126 and 184.

description: Branching ratios for the decay of hadrons with large width or near thresholds depend on their definition. We test different definitions and show that rather different branching ratios can be obtained. For wide resonances and for sequential decays with wide intermediate resonances, integration over the spectral functions is mandatory. The tests are performed exploiting the latest solution of the Bonn-Gatchina multi-channel analysis and published values for residues of light scalar mesons. For a resonance overlapping with a threshold, in case its pole lies in a non-adjacent sheet, we show how the total width, needed for the branching ratios, does not correspond to the imaginary part of the pole position. We use the Madrid-Krakow dispersive parameterizations to illustrate this situation with the $f_0(980)$.

description: When one of the parameters in the Euler-Lagrange equations of motion of a system is modulated, particles can be generated out of the quantum vacuum. This phenomenon is known as the dynamical Casimir effect, and it was recently realized experimentally in systems of superconducting circuits, for example by using modulated resonators made of coplanar waveguides, or arrays of superconducting quantum intereference devices (SQUIDs) forming a Josephson metamaterial. In this paper, we consider a simple electrical circuit model for dynamical Casimir effects, consisting of an LC resonator, with the inductor modulated externally at 10.8 GHz and with the resonant frequency tunable over a range of $\pm$ 400 MHz around 5.4 GHz. The circuit is analyzed classically using a circuit simulator (APLAC). We demonstrate that if an additional source of classical noise couples to the resonator (on top of the quantum vacuum), for example via dissipative "internal modes", then the resulting spectrum of the photons in the cavity will present two strongly asymmetric branches. However, according to the theory of the dynamical Casimir effect, these branches should be symmetric, a prediction which is confirmed by our experimental data. The simulation presented here therefore shows that the origin of the photons generated in our experiment with Josephson metamaterials is the quantum vacuum, and not a spurious classical noise source.

description: Based on the chiral perturbation theory, we investigate the low-energy dynamics of nucleon parton distributions. We show that in different regions of the momentum fraction $x$ the chiral expansion is significantly different. For nucleon parton distributions these regions are characterized by $x\sim1$, $x\sim m_π/M_N$ and $x\sim (m_π/M_N)^2$. We derive extended counting rules for each region and obtain model-independent results for the nucleon parton distributions down to $x\gtrsim m^2_π/M^2_N \approx 10^{-2}$.

Year: 2012

description: O objetivo deste artigo é analisar as perceções dos residentes dos impactes dos casinos e os fatores que influenciam essas perceções. A concretização deste objetivo implicou a aplicação de um inquérito por questionário aos residentes do concelho de Espinho, em 2010, tendo sido obtidos 222 questionários válidos. Os resultados que emergem desta investigação permitem observar que globalmente os residentes do concelho de Espinho consideram que o casino tem impactes positivos, nomeadamente em termos económicos, mas revelam-se atentos aos seus custos socioculturais. Os resultados obtidos também revelam que a perceção dos impactes do casino varia de acordo com o perfil sociodemográfico dos residentes e com o nível de conhecimento e de dependência que detêm desta atividade. O artigo termina com algumas recomendações para o desenvolvimento turístico de destinos onde existem infraestruturas de jogo.

description: Este artigo tem a finalidade de mostrar como a análise prospetiva constitui uma ferramenta que pode potenciar as dimensões exploratória e estratégica do planeamento em turismo em contextos marcados pela mudança acelerada, o risco e outras incertezas e, nessa medida, auxiliar atores e stakeholders nos processos de definição e construção de novos rumos para o turismo. Os estudos prospetivos são hoje uma poderosa ferramenta na área do planeamento e assumem maior pertinência em tempos incertos, balizados pela complexidade e por inúmeros constrangimentos (mas também oportunidades) associados à globalização e à(s) crise(s) que afetam o sistema-mundo. No domínio do Turismo, como noutros, além de informar as políticas, através dos diagnósticos prospetivos que realiza, a análise prospetiva pode potenciar a construção de redes de atores envolvidos na «modelação do futuro» na área da inovação social e, ainda, contribuir para desenvolver capacidades em toda a região no domínio do desenvolvimento de uma “cultura prospetiva”, reforçando o empowerment coletivo e as suas próprias redes. Em síntese, o conhecimento de métodos, técnicas e formas de operacionalização da prospetiva por parte dos atores individuais e coletivos do setor turístico podem ser uma mais-valia diferenciadora e potenciadora de um planeamento estratégico mais informado, participado e partilhado.

description: Programming language documentation refers to the set of technical documents that provide application developers with a description of the high-level concepts of a language. Such documentation is essential to support application developers in the effective use of a programming language. One of the challenges faced by documenters (i.e., personnel that produce documentation) is to ensure that documentation has relevant information that aligns with the concrete needs of developers. In this paper, we present an automated approach to support documenters in evaluating the differences and similarities between the concrete information need of developers and the current state of documentation (a problem that we refer to as the topical alignment of a programming language documentation). Our approach leverages semi-supervised topic modelling to assess the similarities and differences between the topics of Q&A posts and the official documentation. To demonstrate the application of our approach, we perform a case study on the documentation of Rust. Our results show that there is a relatively high level of topical alignment in Rust documentation. Still, information about specific topics is scarce in both the Q&A websites and the documentation, particularly related topics with programming niches such as network, game, and database development. For other topics (e.g., related topics with language features such as structs, patterns and matchings, and foreign function interface), information is only available on Q&A websites while lacking in the official documentation. Finally, we discuss implications for programming language documenters, particularly how to leverage our approach to prioritize topics that should be added to the documentation.
