description: Wine tourism represents a complex ecosystem, covering various fields of research, stakeholder interests, Wine & Food landscapes, territorial & cultural strategies and business perspectives. The Douro territory (North of Portugal) was the first wine region in the world to be demarcated and regulated (1756) and more recently, in 2001, due to its strong cultural identity, the Alto Douro Vinhateiro was classified by UNESCO as a World Heritage Site. This work, which is based on a diverse documental analysis, literature review and field work, aims to suggest a new enotourism “Stakeholder Analysis” model, reinforcing Wine & Food heritage perspective inside the tourism experience. Another objective of our study is to encourage responsible behaviour among all stakeholders to guarantee a balanced approach between business competitiveness, cultural authenticity, site-conservation, landscape promotion and sustainable development. To assure a sustainable Wine Tourism sector, all Douro stakeholders must balance their own business goals and agendas with the territory development vision, wine & food heritage and adopt cooperation strategies in their businesses and territory.

description: We present a global study of low-mass, young stellar object (YSO) surface densities (Σ) in nearby (<500 >pc) star-forming regions based on a comprehensive collection of Spitzer Space Telescope surveys. We show that the distribution of YSO surface densities in the solar neighbourhood is a smooth distribution, being adequately described by a lognormal function from a few to 103 YSOs pc−2, with a peak at ∼22 stars pc−2 and a dispersion of inline image. We do not find evidence for multiple discrete modes of star formation (e.g. clustered and distributed). Comparing the observed surface density distribution to previously reported surface density threshold definitions of clusters, we find that the fraction of stars in clusters is crucially dependent on the adopted definitions, ranging from 40 to 90 per cent. However, we find that only a low fraction (<26 per>cent) of stars are formed in dense environments where their formation/evolution (along with their circumstellar discs and/or planets) may be affected by the close proximity of their low-mass neighbours.

description: We review the current state of experimental knowledge on double ccbar production in e+e- annihilation. The large cross-sections (O(20 fb)) for e+e- -> gamma* -> psi(') ccbar_{res} processes have been confirmed by detailed tests and reproduced by a second group: they should now be considered well-established. The latest experimental results concern the case where the second ccbar system is above open-charm threshold: hidden-charm states continue to play a prominent role in the mass spectrum. Some ``loose ends'' in the field are also briefly discussed.

Experimental evidence of robust acoustic valley Hall edge states in a non-resonant topological elastic waveguide

description: This paper presents experimental evidence of the existence of acoustic valley Hall (AVHE) edge states in topological elastic waveguides. The fundamental lattice is assembled based on a non-resonant unit where space inversion symmetry (SIS) is broken by simply perturbing the underlying lattice geometry. This aspect is in net contrast with existing elastic AVHE designs that exploit locally-resonant units and require the addition of masses in order to break SIS. The experimental results presented in this study validate findings so far presented only at theoretical and numerical level. In particular, it is found that edge modes can effectively propagate along domain walls between topologically dissimilar domains and that disorder-induced backscattering is substantially suppressed due to the weak coupling between oppositely valley-polarized modes. The coupling between valley modes is also further investigated and linked to an evident chiral flux of the mechanical energy. Finally, we show that the weak coupling between the valleys can be exploited to achieve selective mode injection at the domain wall, hence realizing a very effective excitation strategy of the chiral edge states.

Destination image and on-site tourist behaviour: A systematic literature review
Creators: name: Borlido, Tiago

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2021

description: Destination image is a prominent topic in tourism research. While studies on destination image have extensively focused on the role of image in destination selection and consumer loyalty, its impact on tourists’ on-site behaviour is often overlooked. This paper explores this relationship through a systematic literature review of Scopus-indexed research published between 1960 and 2019 concerning this theme, discussing the main findings and methodologies utilized as well as the thematic context in which this research was conducted. Research reveals to be primarily quantitative and addressing several components of destination image. The effects of image on on-site behaviour, although less frequent than those on pre and post-travel behaviour, have been analysed in terms of activities sought, levels of expenditure, length of stay, itinerary choices and behaviours towards accommodation. Based on this analysis, gaps in the academic literature are identified suggesting future avenues of research.

description: Studies analysing the impact of river floods on tourism are scarce and usually approach the impact of such phenomenon on tourism as one of the affected industries. Floods on inland places, as fluvial floods, also affect tourism, particularly on what concerns to tourists’ perceptions of risk. In this context, the present work addresses the effects of flooding on tourism in inland areas. Damage Influencing factors are classified as impact parameters and resistance parameters to obtain an initial assessment of damage to tourism. A case study was carried out in the city of Ourense (Spain) which features spas and thermal facilities located on the river banks. Tourism’s dependency on natural, thermal resources, combined with the fact that such attractions are irremediably located on flood zones, increases the sector’s vulnerability to inundations.

description: Changes in the way of life of societies have led to an intense growth of nightlife tourism around the world, mainly in cities and coastal areas, and expectations are for continued growth in the future. Malpractice in this sector and excesses in the holiday behaviour of groups of tourists, often related to alcohol, have led to the emergence of so-called booze tourism. This phenomenon has a negative impact not only on tourism but also on the safety and daily life of residents. This paper explores governance measures for the efficient management of nightlife, mainly in the face of the problems generated by booze tourism. For this purpose, we evaluate the risk environments and solutions adopted in three locations in Spain, one of the world leaders in the nightlife sector. The analysis includes observations from residents, authorities and citizen protection entities, informal discussions and collection of secondary data. A series of recommendations drawn from empirical experience can be summarised in four key concepts: unity, collaboration, legislation and quality.

description: An arc-search interior-point method is a type of interior-point methods that approximates the central path by an ellipsoidal arc, and it can often reduce the number of iterations. In this work, to further reduce the number of iterations and computation time for solving linear programming problems, we propose two arc-search interior-point methods using Nesterov's restarting strategy that is well-known method to accelerate the gradient method with a momentum term. The first one generates a sequence of iterations in the neighborhood, and we prove that the convergence of the generated sequence to an optimal solution and the computation complexity is polynomial time. The second one incorporates the concept of the Mehrotra-type interior-point method to improve numerical performance. The numerical experiments demonstrate that the second one reduced the number of iterations and computational time. In particular, the average number of iterations was reduced compared to existing interior-point methods due to the momentum term.

description: The project of \emph{"quantum spacetime phenomenology"} focuses on searching pragmatically for the Planck scale quantum features of spacetime. Among these features is the existence of a characteristic length scale addressed commonly by effective approaches to quantum gravity (QG). This characteristic length scale could be realized, for instance and simply, by generalizing the standard Heisenberg uncertainty principle (HUP) to a \emph{"generalized uncertainty principle"} (GUP). While usually it is expected that phenomena belonging to the realm of QG are essentially probable solely at the so-called Planck energy, here we show how a GUP proposal containing the most general modification of coordinate representation of the momentum operator could be probed by a \emph{"cold atomic ensemble recoil experiment"} (CARE) as a low energy quantum system. This proposed atomic interferometer setup has advantages over the conventional architectures owing to the enclosure in a high finesse optical cavity which is supported by a new class of low power consumption integrated devices known as \emph{"micro-electro-opto-mechanical systems"} (MEOMS). The proposed system comprises of a micro mechanical oscillator instead of spherical confocal mirrors as one of the components of high finesse optical cavity. In the framework of a bottom-up QG phenomenological viewpoint and by taking into account the measurement accuracy realized for the fine structure constant (FSC) from the Rubidium ($^{87}$Rb) CARE, we set some constraints as upper bounds on the characteristic parameters of the underlying GUP. In the case of superposition of the possible GUP modification terms, we managed to set a tight constraint as $0.999978

Film tourism meets slum tourism

Year: 2021

description: Previous literature shows that even negative portrayals of destinations in films can increase the audience’s motivations to visit the depicted places. Building on these contributions, more recent studies have shown that films can play a significant role in inducing motivations for slum tourism, that is, tourism to which poverty is part of the attraction. In this context, the present study aims to verify which aspects of films depicting poor urban places are responsible for attracting slum tourists to such destinations. To this end, the investigation builds on previous conceptualisations of how films attract visitors to the portrayed places. Quantitative Data was collected from tourists during their visits to Rio de Janeiro’s favelas, and later subjected to Exploratory (EFA) and Confirmatory Factor Analysis (CFA). Results corroborate a previously proposed conceptualisation according to which slum tourism motivations are affected by two main film determinants. The study is the first to quantitatively corroborate films’ effects on slum tourists’ motivation. Findings also point to relevant insights for destination managers dealing with slum tourism, particularly where it is boosted by films.

description: Sharing information has been democratized with the rise of social networks. Consequently, increasing the usage of Social Network, especially Twitter platform, leads to growing malicious activities. With a silent hack, a hacker can continuously dig around to control over victim’s account. In this paper, an observed direct impact to users’ security and privacy has been identified. Therefore, we address hidden tactics in the problem specific feature engineering with detailed results to show how deep leaning classifiers are promising direction to understand sentiment than classical machine learning. Thus, we focus on the state of the art Deep learning techniques by constructing a model to detect behavioral changes of users. Our evaluation shows that working with just classical machine algorithms to analyse social data do not achieve higher performance than deep learning algorithms. This will open directions for using deep learning for similar problems. Moreover, our results demonstrate the shortages of classical Machine Learning classifiers compared to Deep learning and how they can be mitigated.

description: We propose a novel deterministic method for preparing arbitrary quantum states. When our protocol is compiled into CNOT and arbitrary single-qubit gates, it prepares an $N$-dimensional state in depth $O(\log(N))$ and spacetime allocation (a metric that accounts for the fact that oftentimes some ancilla qubits need not be active for the entire circuit) $O(N)$, which are both optimal. When compiled into the $\{\mathrm{H,S,T,CNOT}\}$ gate set, we show that it requires asymptotically fewer quantum resources than previous methods. Specifically, it prepares an arbitrary state up to error $ε$ with optimal depth of $O(\log(N) + \log (1/ε))$ and spacetime allocation $O(N\log(\log(N)/ε))$, improving over $O(\log(N)\log(\log (N)/ε))$ and $O(N\log(N/ε))$, respectively. We illustrate how the reduced spacetime allocation of our protocol enables rapid preparation of many disjoint states with only constant-factor ancilla overhead -- $O(N)$ ancilla qubits are reused efficiently to prepare a product state of $w$ $N$-dimensional states in depth $O(w + \log(N))$ rather than $O(w\log(N))$, achieving effectively constant depth per state. We highlight several applications where this ability would be useful, including quantum machine learning, Hamiltonian simulation, and solving linear systems of equations. We provide quantum circuit descriptions of our protocol, detailed pseudocode, and gate-level implementation examples using Braket.

description: By combining the continuous matrix product state (cMPS) representation for quantum fields in the continuum with standard optimization techniques for matrix product states (MPS) on the lattice, we obtain an approximation $|Ψ\rangle$, directly in the continuum, of the ground state of non-relativistic quantum field theories. This construction works both for translation invariant systems and in the more challenging context of inhomogeneous systems, as we demonstrate for an interacting bosonic field in a periodic potential. Given the continuum Hamiltonian $H$, we consider a sequence of discretized Hamiltonians $\{H(ε_α)\}_{α=1,2,\cdots,p}$ on increasingly finer lattices with lattice spacing $ε_1 > ε_2 > \cdots > ε_p$. We first use energy minimization to optimize an MPS approximation $|Ψ(ε_1)\rangle$ for the ground state of $H(ε_1)$. Given the MPS $|Ψ(ε_α)\rangle$ optimized for the ground state of $H(ε_α)$, we use it to initialize the energy minimization for Hamiltonian $H(ε_{α+1})$, resulting in the optimized MPS $|Ψ(ε_{α+1})\rangle$. By iteration we produce an optimized MPS $|Ψ(ε_{p})\rangle$ for the ground state of $H(ε_p)$, from which we finally extract the cMPS approximation $|Ψ\rangle$ for the ground state of $H$. Two key ingredients of our proposal are: (i) a procedure to discretize $H$ into a lattice model where each site contains a two-dimensional vector space (spanned by vacuum $|0\rangle$ and one boson $|1\rangle$ states), and (ii) a procedure to map MPS representations from a coarser lattice to a finer lattice.

description: All observations don’t have equal significance in regression analysis. Diagnostics of observations is an important aspect of model building. In this paper, we use diagnostics method to detect residuals and influential points in nonlinear regression for repeated measurement data. Cook distance and Gauss newton method have been proposed to identify the outliers in nonlinear regression analysis and parameter estimation. Most of these techniques based on graphical representations of residuals, hat matrix and case deletion measures. The results show us detection of single and multiple outliers cases in repeated measurement data. We use these techniques to explore performance of residuals and influence in nonlinear regression model.

description: We used multiwavelength data (HI, FUV, NUV, R) to search for evidence of star formation in the intragroup medium of the Hickson Compact Group 100. We find that young star-forming regions are located in the intergalactic HI clouds of the compact group which extend to over 130 kpc away from the main galaxies. A tidal dwarf galaxy candidate is located in the densest region of the HI tail, 61 kpc from the brightest group member and its age is estimated to be only 3.3 Myr. Fifteen other intragroup HII regions and TDG candidates are detected in the GALEX FUV image and within a field 10'x10' encompassing the HI tail. They have ages <200 Myr, HI masses of 10^(9.2-10.4) Msun, 0.001< SFR <0.01 Msun yr^-1, and stellar masses 10^4.3--10^6.5 Msun. The HI clouds to which many of them are associated have column densities about one order of magnitude lower than N(HI)~10^21 cm^-2.

description: O turismo acessível é uma das áreas de investigação em crescimento. Contudo, a maior parte da produção científica dentro desta área aborda a acessibilidade física, havendo muito pouca investigação que foque as barreiras interpessoais, mais concretamente, as atitudes em relação às pessoas com incapacidade. Em Portugal, a maioria dos cursos superiores de turismo não contemplam, nos seus programas curriculares, um módulo dedicado a esta temática. Neste contexto, esta investigação tem como objetivo determinar se os contactos prévios com pessoas com incapacidade (PCI) influenciam o conhecimento que os estudantes, de licenciatura e mestrado da área do turismo, possuem acerca do turismo acessível, bem como as suas atitudes em relação a este grupo de pessoas. Para a concretização destes objetivos foi administrado um questionário a 288 estudantes dos cursos de superiores de turismo. Os resultados sugerem que existem diferenças estatisticamente significativas entre os estudantes que, frequentemente, contactam com pessoas com necessidades especiais, nomeadamente a nível do conhecimento que possuem acerca do segmento de mercado do turismo acessível e das atitudes em relação a este grupo. Este estudo contribui, num plano teórico, para a validação da relação que existe entre a frequência do contacto prévio com PCI e as atitudes em relação a este grupo de pessoas. Por outro lado, a nível prático contribui para que as instituições de ensino superior, técnico-profissionais ou empresas de formação profissional, possam reprogramar os planos curriculares de forma a melhorar as atitudes em relação às pessoas com incapacidade.

description: We show that the commonly used criterion for beta equilibrium in neutrino-transparent dense nuclear matter becomes invalid as temperatures rise above 1 MeV. Such temperatures are attained in neutron star mergers. By numerically computing the relevant weak interaction rates we find that the correct criterion for beta equilibrium requires an isospin chemical potential that can be as large as 10-20 MeV, depending on the temperature at which neutrinos become trapped.

description: Although invertebrate drift is an important ecological process in lotic ecosystems, very little is known about it in Kenyan rivers. The primary aim of this study was to investigate the effect of driftnet mesh size and exposure duration on drift density in 2017. Drift samples were dominated by Chironomidae, Baetidae, Simuliidae, Caenidae and Culicidae. The 100 µm mesh driftnet had the highest mean invertebrate density, followed by the 250 µm and 500 µm nets. Invertebrate drift densities decreased with increased exposure time. This study demonstrates that sampler mesh size and exposure time should be taken into account when characterising invertebrate drift in streams. Future studies should consider sampling different biotopes and during different seasons.

description: Gastronomy and Wines has been a premium food tourism product of the national destination management organization (Tourism of Portugal) since its first National Strategic Plan for Tourism, to the present one with growing visibility and food awards. However, international research points out the emergent need to have in-depth knowledge of this industry, namely on the numerous given denominations and its potential segmentations on the food tourist demand. The main objective of this study is to clarify the nomination for this tourism sector in Portugal and to identify potential food tourism demand segmentations, paired up with the restaurant industry. To this, and due to the present pandemics, an innovative exploratory methodology was created for a food expert focus group, adapted to an online format, using visual stimuli and a computer-assisted qualitative data analysis software. The findings show that, although there was not a general agreeance in the renaming of the tourist food related activities, there was a consensus in the proposed four restaurant typologies and its hypothetical tourist demand segmentation, as presented on intermediate results section. Also, emerged the need for future research on the main food tourist demand markets in Portugal, thus being presented in the last section of this study a structured proposal for the coming research.

description: Flat band systems are currently under intense investigation in quantum materials, optical lattices, and metamaterials. These efforts are motivated by potential realization of strongly correlated phenomena enabled by frustration-induced flat band dispersions; identification of candidate platforms plays an important role in these efforts. Here, we develop a high-throughput materials search for bulk crystalline flat bands by automated construction of uniform-hopping near-neighbor tight binding models. We show that this approach captures many of the essential features relevant to identifying flat band lattice motifs in candidate materials in a computationally inexpensive manner. We apply this algorithm to 139,367 materials in the Materials Project database and identify 63,076 materials that host at least one flat band elemental sublattice. We further categorize these candidate systems into at least 31,635 unique flat band crystal nets and identify candidates of interest from both lattice and band structure perspectives. This work expands the number of known flat band lattices that exist in physically realizable crystal structures and classifies the majority of these systems by the underlying lattice, providing new insights for familiar (e.g. kagome, pyrochlore, Lieb, and dice) as well as previously unknown motifs.

description: To make human settlements more inclusive, safe, resilient and sustainable, as encouraged by SDG#11, and in the sub-goal of 11.4 to “strengthen efforts to protect and safeguard the world’s cultural and natural heritage”, this paper argues that more nuanced understandings are needed of how people relate to nature, including world class nature. The paper furthermore investigates and discusses interpretations and understandings of nature that is not “wild”, untouched, untamed or freed from human intervention and settlement. It advances conceptualizations that benefit efforts to protect and safeguard cultural and natural heritage by providing more nuanced understandings of what nature, respectively culture “is”, using the Danish part of the Wadden Sea (a National Park, parts of which are also a UNESCO Natural World Heritage site) as a relevant case. Based on data collected from 48 research participants by means of various mobile and qualitative methods, variations of interpretations and appreciations of nature voiced by the research participants point to refined understanding of the subtle nuances of nature and culture as a first critical step towards strengthening efforts to protect and safeguard the world’s cultural and natural heritage.

description: In the limit of very fast rotation atomic Bose-Einstein condensates may reside entirely in the lowest two-dimensional Landau level (LLL). For small enough filling factor of the LLL, one may have formation of fractional quantum Hall states. We investigate the case of bosons with dipolar interactions as may be realized with Chromium-52 atoms. We show that at filling factor equal to unity the ground state is a Moore-Read (a.k.a Pfaffian) paired state as is the case of bosons with purely s-wave scattering interactions. This Pfaffian state is destabilized when the interaction in the s-wave channel is small enough and the ground state is a stripe phase with unidimensional density modulation. For filling factor 1/3, we show that there is formation of a Fermi sea of ``composite fermions''. These composites are made of one boson bound with three vortices. This phase has a wide range of stability and the effective mass of the fermions depends essentially only of the scattering amplitude in momentum channels larger or equal to 2. The formation of such a Fermi sea opens up a new possible route to detection of the quantum Hall correlations.

description: We calculate the (super)decomposition matrix for a RoCK block of a double cover of the symmetric group with abelian defect, verifying a conjecture of the first author. To do this, we exploit a theorem of the second author and Livesey that a RoCK block $\mathcal B^{ρ,d}$ is Morita superequivalent to a wreath superproduct of a certain quiver (super)algebra with the symmetric group $\mathfrak S_d$. We develop the representation theory of this wreath superproduct to compute its Cartan invariants. We then directly construct projective characters for $\mathcal B^{ρ,d}$ to calculate its decomposition matrix up to a triangular adjustment, and show that this adjustment is trivial by comparing Cartan invariants.
An Imaging Fabry-Perot System for the Robert Stobie Spectrograph on the Southern African Large Telescope

description: We present the design of the Fabry-Perot system of the Robert Stobie Spectrograph on the 10-meter class Southern African Large Telescope and its characterization as measured in the laboratory. This system provides spectroscopic imaging at any desired wavelength spanning a bandpass 430 - 860 nm, at four different spectral resolving powers ranging from 300 to 9000. Our laboratory tests revealed a wavelength dependence of the etalon gap and parallelism with a maximum variation between 600 - 720 nm that arises because of the complex structure of the broadband multi-layer dielectric coatings. We also report an unanticipated optical effect of this multi-layer coating structure that produces a significant, and wavelength dependent, change in the apparent shape of the etalon plates. This change is caused by two effects: the physical non-uniformities or thickness variations in the coating layers, and the wavelength dependence of the phase change upon refection that can amplify these non-uniformities. We discuss the impact of these coating effects on the resolving power, finesse, and throughput of the system. This Fabry-Perot system will provide a powerful tool for imaging spectroscopy on one of the world's largest telescopes.

description: The aim of this paper is to study the full $K-$moment problem for measures supported on some particular non-linear subsets $K$ of an infinite dimensional vector space. We focus on the case of random measures, that is $K$ is a subset of all non-negative Radon measures on $\mathbb{R}^d$. We consider as $K$ the space of sub-probabilities, probabilities and point configurations on $\mathbb{R}^d$. For each of these spaces we provide at least one representation as a generalized basic closed semi-algebraic set to apply the main result in [J. Funct. Anal., 267 (2014) no.5: 1382--1418]. We demonstrate that this main result can be significantly improved by further considerations based on the particular chosen representation of $K$. In the case when $K$ is a space of point configurations, the correlation functions (also known as factorial moment functions) are easier to handle than the ordinary moment functions. Hence, we additionally express the main results in terms of correlation functions.

description: In this paper we focus on the water waves problem for uneven bottoms on a two-dimensionnal domain. Starting from the symmetric Boussinesq systems derived in [Chazel, Influence of topography on long water waves, 2007], we recover the uncoupled Korteweg-de Vries (KdV) approximation justified by Schneider and Wayne for flat bottoms, and by Iguchi in the context of bottoms tending to zero at infinity at a substantial rate. The goal of this paper is to investigate the validity of this approximation for more general bathymetries. We exhibit two kinds of topography for which this approximation diverges from the Boussinesq solutions. A topographically modified KdV approximation is then proposed to deal with such bathymetries. Finally, all the models involved are numerically computed and compared.
First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration

description: We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005. The search of candidate triggers was performed independently on each of the data sets from single detectors. We looked for two-fold time coincidences between these candidates using an algorithm optimized for a given population of sources and we calculated the efficiency of detection through injections of templated signal waveforms into the streams of data. To this purpose we have considered the case of signals shaped as damped sinusoids coming from the galactic center direction. In this framework our method targets an optimal balance between high efficiency and low false alarm rate, aiming at setting confidence intervals as stringent as possible in terms of the rate of the selected source models.

description: Let $\mathbb{P}$ be the set of prime numbers, $\overline {\mathbb{P}}$ the union $\mathbb{P} \cup \{0\}$, and for any field $E$, let char$(E)$ be its characteristic, ddim$(E)$ the Diophantine dimension of $E$, $\mathcal{G}_{E}$ the absolute Galois group of $E$, and cd$(\mathcal{G}_{E})$ the Galois cohomological dimension $\mathcal{G}_{E}$. The research presented in this paper is motivated by the open problem of whether cd$(\mathcal{G}_{E}) \le {\rm ddim}(E)$. It proves the existence of quasifinite fields $Φ_{q}\colon q \in \mathbb{P}$, with ddim$(Φ_{q})$ infinity and char$(Φ_{q}) = q$, for each $q$. It shows that for any integer $m > 0$ and $q \in \overline {\mathbb{P}}$, there is a quasifinite field $Φ_{m,q}$ such that char$(Φ_{m,q}) = q$ and ddim$(Φ_{m,q}) = m$. This is used for proving that for any $q \in \overline {\mathbb{P}}$ and each pair $k$, $\ell \in (\mathbb{N} \cup \{0, \infty \})$ satisfying $k \le \ell $, there exists a field $E _{k, \ell ; q}$ with char$(E _{k, \ell ; q}) = q$, ddim$(E _{k, \ell ; q}) = \ell $ and cd$(\mathcal{G}_{E_{k, \ell ; q}}) = k$. Finally, we show that the field $E _{k, \ell ; q}$ can be chosen to be perfect unless $k = 0 \neq \ell $.

description: Topological pumping supplies a robust mechanism to steer waves across a sample without being affected by disorders and defects. For the first time, we demonstrate the pumping of elastic surface waves, achieved by a smart patterning of a surface that creates a synthetic dimension, which is explored by the wave as it is launched perpendicularly to the steering direction. Specifically, we design and fabricate an elastic medium decorated with arrays of pillar-type resonators whose eigenmodes are locate below the sound cone, together with coupling bridges edged according to a specific algorithm. We establish a connection between the collective dynamics of the pillars and that of electrons in a magnetic field by deriving an accurate tight-binding model and developing a WKB-type analysis suitable for such discrete aperiodic systems with spatially slow-varying couplings. This enable us to predict topological pumping pattern, which is numerically and experimentally demonstrated by steering waves from one edge of the system to the other. Finally, the immune character of the topologically pumped surface waves against disorder and defects is evidenced. The principle of surface patterning together with the WKB-analysis could provide a powerful new platform for surface wave control and exploration of topological matter in higher dimensions.
