A serra da Lousã: a afirmação de um destino turístico emergente
Creators: name: Fontes, António
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2006

description: A atividade turística deixou de estar confinada a determinados espaços e contextos, cada vez mais os turistas estão em todo o lado e cada vez mais propensos a encontrar alternativas aos enclaves turísticos originalmente promovidos para os satisfazer. Desde toda a década de 80, a Serra da Lousã passou a ser procurada por turistas externos à procura de modos de vida alternativos e por turistas nacionais influenciados pela mudança de hábitos de férias. O aumento dos níveis de vida e do rendimento disponível, a democratização das viagens, a melhoria das acessibilidades para o interior, a crescente urbanização do país e a maior taxa de motorização dos portugueses foram fatores decisivos para que, do lado da procura, se gerassem condições objetivas para o crescimento da atividade turística fora dos destinos tradicionais, localizados no litoral Tendo por base a trilogia de ordenamento dos usos da Serra, investimento sustentável e organização turística, pretende-se entender se o processo organizativo do tipo de uma DMO (Destination Marketing Organization) poderá ter um importante papel para a promoção de um processo de desenvolvimento turístico sustentável na Serra da Lousã, que possa beneficiar o setor do turismo e as populações locais. O desenvolvimento deste artigo poderá proporcionar o “reinventar” do conceito de tradicional de destino turístico deixando de ser espontâneo, que se organiza para servir o turista sempre da mesma forma (industrializada) desencadeando um processo em que os parceiros turísticos se organizam para servir cada turista de forma única e diferenciada.

description: We show how astrometric and spectroscopic errors introduced by an unresolved binary system can be combined to give estimates of the binary period and mass ratio. This can be performed analytically if we assume we see one or more full orbits over our observational baseline, or numerically for all other cases. We apply this method to Gaia DR3 data, combining the most recent astrometric and spectroscopic data. We compare inferred periods and mass ratios calculated using our method with orbital parameters measured for non-single stars in Gaia DR3 and find good agreement. Finally, we use this method to search the subset of the Gaia DR3 RVS dataset with rv_method_used=1 for compact object candidates. We select sources with significant astrometric and spectroscopic errors ($RUWE_{ast}>1.25$ and $RUWE_{spec}>2$), with large inferred mass ratios, and large inferred companion masses ($q>1$ and $M_c>3 M_\odot$) giving a catalogue of 4,641 candidate hierarchical triples and Main Sequence+Compact Object pairs. We apply more stringent cuts, and impose low levels of photometric variability to remove likely triples ($RUWE_{phot}<2$) producing a gold sample of 45 candidates.

description: We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circuits with two different control schemes: pulse amplitude modulation (PAM) and pulse width modulation (PWM). We realize a compact spiral TOPS and a 288-element high-density row-column TOPS array with this architecture and drive TOPS with waveforms of both control schemes and of different array sizes. We present a thermal excitation model and a finite difference method-based simulation to simulate large-scale TOPS arrays and compare both schemes experimentally and theoretically. We also analyze the effects of thermal crosstalk in the realized TOPS array and implement a thermal crosstalk correction algorithm with the developed model. The high-density TOPS array architecture and the thermal crosstalk correction algorithm pave the way for high-density TOPS arrays with independent phase control in large-scale photonic integrated circuits interfaced with electronics limited in voltage swing and bandwidth.

description: We construct stellar models of hadron stars and hybrid stars and calculate the frequencies of their lowest radial mode of vibration. Chandrasekhar's equation for radial oscillations is generalized for stars with internal electric fields and earlier versions of that generalization are simplified. For the hybrid stars a Gibbs construction is employed. It is found that the softening of the equation of state associated with the presence of deconfined quarks reduces the oscillation frequency. We show that a slight charge inbalance should lead to increased maximum mass, decreased central density and lower oscillation frequencies.

description: Main-belt asteroids have been continuously colliding with one another since they were formed. Its size distribution is primarily determined by the size dependence of asteroid strength against catastrophic impacts. The strength scaling law as a function of body size could depend on collision velocity, but the relationship remains unknown especially under hypervelocity collisions comparable to 10 km/sec. We present a wide-field imaging survey at ecliptic latitude of around 25 deg for investigating the size distribution of small main-belt asteroids which have highly inclined orbits. The analysis technique allowing for efficient asteroid detections and high-accuracy photometric measurements provide sufficient sample data to estimate the size distribution of sub-km asteroids with inclinations larger than 14 deg. The best-fit power-law slopes of the cumulative size distribution is 1.25 +/- 0.03 in the diameter range of 0.6-1.0 km and 1.84 +/- 0.27 in 1.0-3.0 km. We provide a simple size distribution model that takes into consideration the oscillations of the power-law slope due to the transition from the gravity-scaled regime to the strength-scaled regime. We find that the high-inclination population has a shallow slope of the primary components of the size distribution compared to the low-inclination populations. The asteroid population exposed to hypervelocity impacts undergoes collisional processes that large bodies have a higher disruptive strength and longer life-span relative to tiny bodies than the ecliptic asteroids.

description: Atualmente a aldeia reassume uma elevada centralidade no nosso mundo. Nas Aldeias do Xisto assistisse-se ao ressurgir de novas comunidades, que voltam a insuflar de vida esses espaços de partilha. Pessoas que procuram um novo estilo de vida, em comunhão com as populações locais e com as suas tradições. A aldeia “reclama” o seu lugar de direito na vida moderna e molda alternativas. As pessoas e empresas que fazem das Aldeias do Xisto o centro do seu mundo têm, em comum, a vontade de que a preservação e a promoção do meio rural sejam os pilares de um novo estilo de vida e de uma nova economia sustentada. Ao longo dos últimos anos, 23 Aldeias do Xisto distribuídas por 13 Municípios do Pinhal Interior foram alvo de um programa de requalificação que permitiu às aldeias adquirir potencial humano de desenvolvimento. É objetivo deste artigo refletir sobre o desenvolvimento deste projeto subjacente a uma logica de sustentabilidade e às transformações que ocorreram no território com a implementação desta rede. Da análise dos resultados deste artigo prevê-se que possam surgir uma nova base económica através da recuperação das tradições, da valorização do património arquitetónico construído, da dinamização das artes e ofícios tradicionais e da defesa e preservação da paisagem em que se enquadram.

Os trilhos pedestres como uma actividade de lazer, recreio e turismo – uma análise exploratória ao mercado dos trilhos pedestres em Portugal
Creators: name: Rodrigues, Áurea
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2006

description: O pedestrianismo tem vindo a ganhar um grande relevo como actividade de lazer e de turismo em muitos países. Portugal possui muitos recursos que permitem a prática desta actividade, no entanto, o país ainda não descobriu o potencial turístico do pedestrianismo. O presente artigo discute o potencial dos trilhos pedestres como uma infraestrutura turística que pode ser desenvolvida com o intuito de contribuir, de uma forma sustentável, para o desenvolvimento do turismo em áreas rurais de Portugal. Para se desenhar trilhos com capacidade de atrair visitants torna-se necessário conhecer os desejos e necessidades do mercado, tanto a nível dos praticantes como dos “não praticantes” para se poder converter este grupo em “pedestrianistas”. Este estudo de âmbito exploratório apresenta os resultados de uma análise efectuada ao perfil dos pedestrianistas portugueses, pedestrianistas de outras nacionalidades e de “não pedestrianistas” portugueses. Comparando pedestrianistas portugueses com pedestrianistas estrangeiros, notam-se algumas diferenças significativas ao nível do comportamento e atitude ambiental e no contexto de férias. A comparação dos pedestrianistas ainda com um grupo de portugueses que não costumam caminhar na natureza, permite compreender diferenças de comportamento e atitudes que possam originar a falta de interesse por trilhos pedestres neste último grupo, e, simultaneamente, identificar variáveis que possam converter também este grupo em pedestrianistas. Pretende-se, com isso, dar um contributo para promover os trilhos pedestres enquanto infra-estruturas turísticas e apoiar uma gestão sustentável dos mesmos, baseada na capacidade de adaptação às preferências e aos receios de cada grupo.

description: Microarrays are made it possible to simultaneously monitor the expression profiles of thousands of genes under various experimental conditions. Identification of co-expressed genes and coherent patterns is the central goal in microarray or gene expression data analysis and is an important task in bioinformatics research. Feature selection is a process to select features which are more informative. It is one of the important steps in knowledge discovery. The problem is that not all features are important. Some of the features may be redundant, and others may be irrelevant and noisy. In this work the unsupervised Gene selection method and Enhanced Center Initialization Algorithm (ECIA) with K-Means algorithms have been applied for clustering of Gene Expression Data. This proposed clustering algorithm overcomes the drawbacks in terms of specifying the optimal number of clusters and initialization of good cluster centroids. Gene Expression Data show that could identify compact clusters with performs well in terms of the Silhouette Coefficients cluster measure.

description: O turismo e o desporto são dois fatores que se entrelaçam e se condicionam mutuamente. O desporto pode ser determinante para a programação de uma viagem contribuindo desta forma para a mobilização de grandes fluxos de visitantes, e consequentemente pode usufruir das infraestruturas e serviços turísticos existentes. As pessoas que se deslocam para participarem de modo ativo ou para assistirem a eventos desportivos, os visitantes, tomam conhecimento da cultura, tradições e gastronomia da região onde o evento é realizado. O desporto proporciona visibilidade e contribui para a promoção da imagem dos destinos turísticos. Neste sentido podemos afirmar que o turismo desportivo pode ser um importante veículo para a promoção de uma região, potenciando o seu desenvolvimento e a sustentação da base económica local. Este artigo pretende promover uma reflexão sobre a importância da modalidade desportiva – rugby para a promoção do destino turístico Lousã. Estamos conscientes que esta divulgação proporciona um impacte positivo no número de dormidas nesta região. E, consequentemente permite aferir a importância e o contributo do desporto para a dinamização turística e cultural de um destino.

An empirical approach to model selection: weak lensing and intrinsic alignments

description: In cosmology, we routinely choose between models to describe our data, and can incur biases due to insufficient models or lose constraining power with overly complex models. In this paper we propose an empirical approach to model selection that explicitly balances parameter bias against model complexity. Our method uses synthetic data to calibrate the relation between bias and the $χ^2$ difference between models. This allows us to interpret $χ^2$ values obtained from real data (even if catalogues are blinded) and choose a model accordingly. We apply our method to the problem of intrinsic alignments -- one of the most significant weak lensing systematics, and a major contributor to the error budget in modern lensing surveys. Specifically, we consider the example of the Dark Energy Survey Year 3 (DES Y3), and compare the commonly used nonlinear alignment (NLA) and tidal alignment & tidal torque (TATT) models. The models are calibrated against bias in the $Ω_m - S_8$ plane. Once noise is accounted for, we find that it is possible to set a threshold $Δχ^2$ that guarantees an analysis using NLA is unbiased at some specified level $Nσ$ and confidence level. By contrast, we find that theoretically defined thresholds (based on, e.g., $p-$values for $χ^2$) tend to be overly optimistic, and do not reliably rule out cosmological biases up to $\sim 1-2σ$. Considering the real DES Y3 cosmic shear results, based on the reported difference in $χ^2$ from NLA and TATT analyses, we find a roughly $30\%$ chance that were NLA to be the fiducial model, the results would be biased (in the $Ω_m - S_8$ plane) by more than $0.3σ$. More broadly, the method we propose here is simple and general, and requires a relatively low level of resources. We foresee applications to future analyses as a model selection tool in many contexts.

description: INTEGRAL is a hard X-ray/gamma-ray observatory for astrophysics (ESA) covering photon energies from 15 keV to 10 MeV. It was launched in 2002 and since then the BGO detectors of the Anti-Coincidence shield (ACS) of the SPI spectrometer have detected many hard X-ray (HXR) bursts from the Sun, producing lightcurves at photon energies above ~ 100 keV. The spacecraft has a highly elliptical orbit, providing a long uninterrupted observing time (about 90% of the orbital period) with nearly constant background due to the reduction of the crossing time of the Earth's radiation belts. However, due to technical constraints, INTEGRAL cannot point to the Sun and high-energy solar photons are always detected in non-standard observation conditions. To make the data useful for solar studies, we have undertaken a major effort to specify the observing conditions through Monte-Carlo simulations of the response of ACS for several selected flares. We check the performance of the model employed for the Monte-Carlo simulations using RHESSI observations for the same sample of solar flares. We conclude that, despite the fact that INTEGRAL was not designed to perform solar observations, ACS is a useful instrument in solar flare research. In particular, its relatively large effective area allows the determination of good-quality HXR/gamma-ray lightcurves for X- and M-class solar flares and, in some cases, probably also for C-class flares.

description: Cycling is a crucial part of sustainable urban transportation. Promoting cycling critically relies on a sufficiently developed bicycle infrastructure. However, designing efficient bike path networks constitutes a complex problem that requires balancing multiple constraints while still supporting all cycling demand. Here, we propose a framework to create families of efficient bike path networks by explicitly taking into account the demand distribution and cyclists' route choices based on safety preferences. By reversing the network formation process and iteratively removing bike paths from an initially complete bike path network and continually updating cyclists' route choices, we create a sequence of networks that is always adapted to the current cycling demand. We illustrate the applicability of this demand-driven planning scheme for two cities. A comparison of the resulting bike path networks with those created for homogenized demand enables us to quantify the importance of the demand distribution for network planning. The proposed framework may thus enable quantitative evaluation of the structure of current and planned bike path networks and support the demand-driven design of efficient infrastructures.

description: In this work we study the $D^* \bar{D}^*$ current with QCD sum rules. We write the correlation function using the general current corresponding to the $D^* \bar{D}^*$ system and then use spin projectors to obtain the correlation function in the $0^+, 1^+$ and $2^+$ spin-parity configurations. The purpose of the present work is to investigate the possibility of explaining the recently reported $Z_c(4025)$ as a $D^* \bar{D}^*$ moleculelike state. As a result we find a state for each spin case with a very similar mass: $M^{S=0} = \left(3943 \pm 104\right)$ MeV, $M^{S=1} = \left(3950 \pm 105\right)$ MeV, $M^{S=2} = \left(3946 \pm 104 \right)$ MeV. We discuss that our mass results, within error bars, for $1^+$ or $2^+$ are both compatible with $Z_c(4025)$. However, our results are also compatible with a possible $D^* \bar{D}^*$ bound state, in agreement with predictions of some previous works. We have also calculated the current-state coupling which turns out to be larger in the $2^+$ case.

description: O homem é um ser cultural, que gosta de conhecer o que é diferente, facto que constitui uma forte motivação para fazer turismo. O turismo de sol e mar é massificado, comparativamente com outras alternativas em diversas geografias onde se valoriza o contacto com a natureza, o património, os costumes locais e as características diferenciadoras. É uma modalidade turística de maior qualidade que começa a despontar no Interior através de algumas iniciativas pontuais e pode vir a ser um potencial redutor do fator sazonalidade. O presente texto procura refletir quais os fatores chave da afirmação de um projeto de desenvolvimento turístico na Aldeia Histórica de Marialva. Tem como objetivos criar um conceito que responda às expectativas do viajante contemporâneo o conceito de um hotel com atmosfera. Pretende-se criar uma alternativa válida ao turismo de massas que responda às tendências do mercado atual e a uma procura de espaços não convencionais. A análise dos resultados prevê-se que nos permita concluir sobre a importância de um nova centralidade que pode representar um enorme potencial atrativo para muitos visitantes.

description: The Drell-Yan massive lepton-pair production in hadronic collisions provides a unique tool complementary to the Deep-Inelastic Scattering for probing the partonic substructures in hadrons. We review key concepts, approximations, and progress for QCD factorization of the Drell-Yan process in terms of collinear or transverse momentum dependent (TMD) parton distribution functions. We present experimental results from recent fixed-target Drell-Yan as well as $W$ and $Z$ boson production at colliders, focussing on the topics of flavor structure of the nucleon sea as well as the extraction of novel Sivers and Boer-Mulders functions via single transverse spin asymmetries and azimuthal lepton angular distribution of the Drell-Yan process. Prospects for future Drell-Yan experiments are also presented.

In our approach, the photonic hyperentanglement and quantum Fourier transform are both utilized. The presented proposal will be useful for the high-dimensional multi-photon quantum computation and quantum communication.

The influence of the Thomas precession of the observer's frame has an important role. The equations of motion are based on a nonlinear connection modified by the action of an orthogonal tensor which synchronizes the 4-velocities of the considered two bodies. Finally we present periastron shift according to an observer inside the gravitational field, using the orthonormal coordinates. This is different approach than that used in General Relativity where the periastron shift is only given as observed far from the massive bodies.

description: A common theme in causal inference is learning causal relationships between observed variables, also known as causal discovery. This is usually a daunting task, given the large number of candidate causal graphs and the combinatorial nature of the search space. Perhaps for this reason, most research has so far focused on relatively small causal graphs, with up to hundreds of nodes. However, recent advances in fields like biology enable generating experimental data sets with thousands of interventions followed by rich profiling of thousands of variables, raising the opportunity and urgent need for large causal graph models. Here, we introduce the notion of factor directed acyclic graphs (f-DAGs) as a way to restrict the search space to non-linear low-rank causal interaction models. Combining this novel structural assumption with recent advances that bridge the gap between causal discovery and continuous optimization, we achieve causal discovery on thousands of variables. Additionally, as a model for the impact of statistical noise on this estimation procedure, we study a model of edge perturbations of the f-DAG skeleton based on random graphs and quantify the effect of such perturbations on the f-DAG rank. This theoretical analysis suggests that the set of candidate f-DAGs is much smaller than the whole DAG space and thus may be more suitable as a search space in the high-dimensional regime where the underlying skeleton is hard to assess. We propose Differentiable Causal Discovery of Factor Graphs (DCD-FG), a scalable implementation of -DAG constrained causal discovery for high-dimensional interventional data. DCD-FG uses a Gaussian non-linear low-rank structural equation model and shows significant improvements compared to state-of-the-art methods in both simulations as well as a recent large-scale single-cell RNA sequencing data set with hundreds of genetic interventions.

description: The transition quadrupole moments, $Q_{t}$, of rotational bands in the neutron-rich, even-mass $^{102-108}$Mo and $^{108-112}$Ru nuclei were measured in the 8 to 16 $\hbar $ spin range with the Doppler-shift attenuation method. The nuclei were populated as fission fragments from $^{252}$Cf fission. The detector setup consisted of the Gammasphere spectrometer and the HERCULES fast-plastic array. At moderate spin, the $Q_{t}$ moments are found to be reduced with respect to the values near the ground states. Attempts to describe the observations in mean-field-based models, specifically cranked relativistic Hartree-Bogoliubov theory, illustrate the challenge theory faces and the difficulty to infer information on $γ$ softness and triaxiality from the data.

description: The Schwarzschild black hole metric with mass $M$ has the limit of the vanishing mass when one get the Minkowski space. We study behavior of the entanglement entropy by using the island formula and the limit of the vanishing black hole mass. The black hole information problem appears if one considers the lowering its mass. It was noted recently that the formula derived for eternal black holes leads to an increase of the entanglement entropy, which is singular when $M \to 0$. In this process, it arises the other problem of the Schwarzschild black hole explosion, as the black hole temperature blows up as the mass vanishes.We show that it is possible to solve the entropy explosion for small masses, if one admit the following bound: $c
A Hybrid Modelling Approach for Aerial Manipulators

description: Aerial manipulators (AM) exhibit particularly challenging, non-linear dynamics; the UAV and the manipulator it is carrying form a tightly coupled dynamic system, mutually impacting each other. The mathematical model describing these dynamics forms the core of many solutions in non-linear control and deep reinforcement learning. Traditionally, the formulation of the dynamics involves Euler angle parametrization in the Lagrangian framework or quaternion parametrization in the Newton-Euler framework. The former has the disadvantage of giving birth to singularities and the latter of being algorithmically complex. This work presents a hybrid solution, combining the benefits of both, namely a quaternion approach leveraging the Lagrangian framework, connecting the singularity-free parameterization with the algorithmic simplicity of the Lagrangian approach. We do so by offering detailed insights into the kinematic modeling process and the formulation of the dynamics of a general aerial manipulator. The obtained dynamics model is validated experimentally against a real-time physics engine. A practical application of the obtained dynamics model is shown in the context of a computed torque feedback controller (feedback linearization), where we analyze its real-time capability with increasingly complex models.

Turbulent drag reduction by spanwise wall forcing. Part 1: Large-eddy simulations

description: Turbulent drag reduction through streamwise travelling waves of spanwise wall oscillation is investigated over a wide range of Reynolds numbers. Here, in Part 1, wall-resolved large-eddy simulations in a channel flow are conducted to examine how the frequency and wavenumber of the travelling wave influence the drag reduction at friction Reynolds numbers $Re_τ= 951$ and $4000$. The actuation parameter space is restricted to the inner-scaled actuation (ISA) pathway, where drag reduction is achieved through direct attenuation of the near-wall scales. The level of turbulence attenuation, hence drag reduction, is found to change with the near-wall Stokes layer protrusion height $\ell_{0.01}$. A range of frequencies is identified where the Stokes layer attenuates turbulence, lifting up the cycle of turbulence generation and thickening the viscous sublayer; in this range, the drag reduction increases as $\ell_{0.01}$ increases up to $30$ viscous units. Outside this range, the strong Stokes shear strain enhances near-wall turbulence generation leading to a drop in drag reduction with increasing $\ell_{0.01}$. We further find that, within our parameter and Reynolds number space, the ISA pathway has a power cost that always exceeds any drag reduction savings. This motivates the study of the outer-scaled actuation (OSA) pathway in Part 2, where drag reduction is achieved through actuating the outer-scaled motions.
