description: A adesão, em 1986, de Portugal e Espanha à, então, Comunidade Económica Europeia, veio trazer uma nova possibilidade de aproximação económica e social entre os dois estados. O turismo tem servido aos poucos como um instrumento de cooperação transfronteiriça. Neste texto analisou-se o turismo transfronteiriço luso-galego numa perspetiva de análise da cooperação em âmbitos como a promoção, a articulação empresarial e as mobilidades transfronteiriças. Com base numa aproximação metodológica de análise documental e um quadro teórico que entende o turismo transfronteiriço como um instrumento de redefinição das identidades, a atenção foi focada nalguns projetos de cooperação turística euro-regional, tendo-se concluído que esses esforços devem intensificar-se e melhor coordenar-se.

description: Many neurotoxic chemicals are used in the workplace but there is currently no database dedicated to neurotoxicity. We aimed to develop a classification method for neurotoxicity based on a weight-of-evidence approach, similar to the IARC classification for carcinogenicity. Human and animal lines of evidence were collected from recent toxicological profiles and a literature search and were combined into six groups from neurotoxic to potentially not neurotoxic. The method was tested on 26 chemicals, mixtures or group of products used in the workplace in France: 31% were considered neurotoxic, 31% probably and 11% possibly neurotoxic, and 27% not classifiable because of insufficient data. This operational method suggests that many chemicals used in the workplace are neurotoxic and that questionnaires used to collect data on occupational chemical exposure should propose items with more targeted compounds that have common chemical or toxic properties to improve risk assessment.

description: We show, both theoretically and experimentally, that high-numerical-aperture (NA) optical microscopy is accompanied by strong spin-orbit interaction of light, which translates fine infomation about the specimen to the polarization degrees of freedom of light. An 80nm gold nano-particle scattering the light in the focus of a high-NA objective generates angular momentum conversion which is seen as a non-uniform polarization distribution at the exit pupil. We demonstrate remarkable sensitivity of the effect to the position of the nano-particle: Its subwavelength displacement produces the giant spin-Hall effect, i.e., macro-separation of spins in the outgoing light. This brings forth a far-field optical nanoprobing technique based on the spin-orbit interaction of light.

Year: 2014

description: As an artistic and cultural phenomenon, Dong Ka Lau (Dong Chorus) ontology and its associated social, cultural and natural environment have begun to concern many experts and scholars at home and abroad, as well as local governments. On the basis of a field survey, this paper makes an investigation as to whether Dong Ka Lau will continue to manifest Dong minority people’s aesthetic consciousness and pursuits amid today’s rapidly developing local tourism economy. In addition, the influence on contemporary young people is also of great concern. The study found that commercial performance of Dong Ka Lau heritage in some Dong villages has lost its original cultural significance, while in other villages it has been a vital and inspirational tourism product, of which forms and cultural essence can still exist over a prolonged period of time. This research asserts that cultural ecological self-sustainability and identity can be strengthened and nourished by both external regulations on cultural displays as well as the endogenous power of ethnic minority villages.

description: Essa pesquisa buscou verificar a relação que o homem possui com áreas naturais e entender como está sendo desenvolvido o ecoturismo nessas áreas, sobretudo na Área de Proteção Ambiental (APA) Corumbataí-Botucatu-Tejupá. Considerando o interesse do homem sobre a natureza, existem duas vertentes intrigantes e opostas: ora sua interpretação é de patrimônio natural e outrora, como mais um recurso a ser explorado pelas forças dominantes de mercado. Nesse contexto, surgem alguns conflitos de interesses e a dialética do próprio significado do chamado ecoturismo. É possível a existência das atividades de turismo que não gere impactos e transformações? O que é o ecoturismo? É mais uma adaptação do sistema dominante a fim de atender novas demandas ou a panaceia e salvação para a natureza e comunidade local? Essas questões são polêmicas e talvez sem uma única resposta. O fato é que há uma tensão de conflitos neste espaço, enquanto uns lutam pela conservação, outros defendem seus interesses econômicos de desenvolvimento da infraestrutura para o lazer e turismo. Para o entendimento desses conflitos, os instrumentos utilizados foram: revisão bibliográfica, visita de campo, caderno de campo, palestras com gestor da APA, Secretária do Meio Ambiente e Secretária do Turismo de Brotas. Com base nesta metodologia aplicada foi possível a obtenção de base para a argumentação e entendimento das questões levantadas.

description: A crescente adoção das redes sociais, a par da tendencial disseminação do uso de dispositivos móveis (smartphones e tablets), tem transformado o modo como consumidores e empresas turísticas interagem entre si. Mais do que uma simples alteração nos meios e ferramentas de comunicação, são novos paradigmas que tendem a reinventar a gestão do produto, do preço, da distribuição e da comunicação dos serviços turísticos e, consequentemente, os modelos e processos de marketing management das empresas turísticas. O contributo central do presente artigo para a investigação traduz-se na sistematização dos novos paradigmas comunicacionais que estão na base de um novo ambiente designado de i-turismo, no qual proliferam as tecnologias móveis e as redes sociais. Através da compreensão deste ambiente, projeta-se o novo ciclo de vida das experiências turísticas, identificando os novos modelos e processos de marketing management adotados pelas empresas turísticas. A referida análise terá a matriz de marketing mix como referencial, explorando as alterações e tendências de gestão em cada uma das suas dimensões (preço, produto, comunicação e distribuição: 4P’s). A revisão do estado da arte no presente domínio de investigação, a par do recurso a diferentes relatórios e estudos de caso referenciados como boas práticas, foram procedimentos de investigação fundamentais para a elaboração do presente artigo.

description: Marginal structural models were introduced in order to provide estimates of causal effects from interventions based on observational studies in epidemiological research. The key point is that this can be understood in terms of Girsanov's change of measure. This offers a mathematical interpretation of marginal structural models that has not been available before. We consider both a model of an observational study and a model of a hypothetical randomized trial. These models correspond to different martingale measures -- the observational measure and the randomized trial measure -- on some underlying space. We describe situations where the randomized trial measure is absolutely continuous with respect to the observational measure. The resulting continuous-time likelihood ratio process with respect to these two probability measures corresponds to the weights in discrete-time marginal structural models. In order to do inference for the hypothetical randomized trial, we can simulate samples using observational data weighted by this likelihood ratio.

description: We discuss the interference in the two-particle distribution of the electrons emitted from two independent superconductors. It is clarified that, while the interference appearing in the antibunching correlation is due to the Hanbury Brown and Twiss effect, that in the positive correlation due to superconductivity is intrinsically different and is nothing but the first-order interference of Cooper pairs emitted from different sources. This is the equivalent of the interference of two independent Bose-Einstein condensates.

description: We discuss the classical statistics of isolated subsystems. Only a small part of the information contained in the classical probability distribution for the subsystem and its environment is available for the description of the isolated subsystem. The "coarse graining of the information" to micro-states implies probabilistic observables. For two-level probabilistic observables only a probability for finding the values one or minus one can be given for any micro-state, while such observables can be realized as classical observables with sharp values on a substate level. For a continuous family of micro-states parameterized by a sphere all the quantum mechanical laws for a two-state system follow under the assumption that the purity of the ensemble is conserved by the time evolution. The non-commutative correlation functions of quantum mechanics correspond to the use of conditional correlation functions in classical statistics. We further discuss the classical statistical realization of entanglement within a system corresponding to four-state quantum mechanics. We conclude that quantum mechanics can be derived from a classical statistical setting with infinitely many micro-states.

description: O presente trabalho apresenta uma discussão sobre as transformações do modo de vida no ambiente rural sob o ponto de vista da atividade turística concebida como um sistema aberto e dinâmico, enfatizando os processos de inovação, planejamento e valorização da vida no campo. Para tanto, objetiva-se abordar o caso do projeto de agroturismo ‘Acolhida na Colônia’ no município de Santa Rosa de Lima em Santa Catarina – Brasil, o qual destaca-se na iniciativa de promover no ambiente rural a revalorização das atividades rurais através da perspectiva do turismo de base comunitária. Para viabilizar a pesquisa e o desenvolvimento do trabalho caracterizou-se o estudo como exploratório e descritivo, atentando-se para uma perspectiva qualitativa. Sendo assim, utilizou-se como instrumentos de coletas de dados as pesquisas bibliográficas, documental e estudo de caso, o qual se valeu dos procedimentos técnicos de levantamento através de inquéritos por entrevista semiestruturada e observação assistemática. Após análise, concluiu-se que o ambiente do agroturismo em Santa Rosa de Lima e região permite o desenvolvimento das atividades comerciais do turismo no ambiente rural, mas sem fomentar as implicações habituais do uso intensivo e da exclusão social.

description: Water distribution networks optimization is a challenging problem due to the dimension and the complexity of these systems. Since the last half of the twentieth century this field has been investigated by many authors. Recently, to overcome discrete nature of variables and non linearity of equations, the research has been focused on the development of heuristic algorithms. This algorithms do not require continuity and linearity of the problem functions because they are linked to an external hydraulic simulator that solve equations of mass continuity and of energy conservation of the network.
In this work, a NSGA-II (Non-dominating Sorting Genetic Algorithm) has been used. This is a heuristic multi-objective genetic algorithm based on the analogy of evolution in nature. Starting from an initial random set of solutions, called population, it evolves them towards a front of solutions that minimize, separately and contemporaneously, all the objectives. This can be very useful in practical problems where multiple and discordant goals are common.
Usually, one of the main drawback of these algorithms is related to time consuming: being a stochastic research, a lot of solutions must be analized before good ones are found. Results of this thesis about the classical optimal design problem shows that is possible to improve results modifying the mathematical definition of objective functions and the survival criterion, inserting good solutions created by a Cellular Automata and using rules created by classifier algorithm (C4.5). This part has been tested using the version of NSGA-II supplied by Centre for Water Systems (University of Exeter, UK) in MATLAB® environment. Even if orientating the research can constrain the algorithm with the risk of not finding the optimal set of solutions, it can greatly improve the results.
Subsequently, thanks to CINECA help, a version of NSGA-II has been implemented in C language and parallelized: results about the global parallelization show the speed up, while results about the island parallelization show that communication among islands can improve the optimization.
Finally, some tests about the optimization of pump scheduling have been carried out. In this case, good results are found for a small network, while the solutions of a big problem are affected by the lack of constraints on the number of pump switches. Possible future research is about the insertion of further constraints and the evolution guide.
In the end, the optimization of water distribution systems is still far from a definitive solution, but the improvement in this field can be very useful in reducing the solutions cost of practical problems, where the high number of variables makes their management very difficult from human point of view.
O desenvolvimento do turismo em destinos rurais: perceções dos impactes, interação e atitudes dos residentes

description: A procura turística de áreas rurais tem aumentado consideravelmente nos últimos anos, consequência, por uma lado, das alterações nas necessidades e desejos dos visitantes e, por outro, das estratégias, que têm sido adotadas para estes espaços incorporarem o turismo como uma das atividades económicas a desenvolver. Devido às características destes espaços, o turismo poderá ter um papel fundamental na sua revitalização económica e social. No entanto, esta atividade quando não é desenvolvida de forma planeada, integrando todos os stakeholders, poderá ter implicações negativas, tanto na esfera económica, como a nível sociocultural e ambiental. Neste contexto, este artigo analisa a interação, as perceções dos residentes dos impactes do turismo e as suas atitudes face ao desenvolvimento da atividade turística em pequenos destinos rurais, localizados na Região Centro de Portugal. Para a concretização deste objetivo, foi administrado um inquérito por questionário a uma amostra de residentes de um grupo de Aldeias de Xisto. Os resultados obtidos revelam que os residentes percecionam, essencialmente, os impactes económicos e socioculturais positivos do turismo, interagem pouco com os visitantes e têm uma atitude muito positiva face ao desenvolvimento desta atividade. O artigo termina com algumas linhas orientadoras que devem ser adotadas, no desenvolvimento dos destinos turísticos rurais em análise, para que a atitude positiva dos residentes face ao turismo continue a ser uma realidade no futuro.

description: We consider the problem of demodulating M-ary optical PPM (pulse-position modulation) waveforms, and propose a structured receiver whose mean probability of symbol error is smaller than all known receivers, and approaches the quantum limit. The receiver uses photodetection coupled with optimized phase-coherent optical feedback control and a phase-sensitive parametric amplifier. We present a general framework of optical receivers known as the conditional pulse nulling receiver, and present new results on ultimate limits and achievable regions of spectral versus photon efficiency tradeoffs for the single-spatial-mode pure-loss optical communication channel.

Turismo, ‘autenticidade’ e reprodução serial da cultura
Creators: name: Santos, José Manuel Figueiredo
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2014

description: Este artigo ensaia a problematização do controlo turístico da cultura. Nele, interroga-se a ‘autenticidade’, incorporando na sua agenda os efeitos performativos do turismo. Entendido o turismo pelo que Appadurai (1990) designa de ethnoscape, significando com isso a requisição da cultura como esfera transacionável para a sua operatividade, nele ganham centralidade antinomias analíticas deduzidas do seu papel estrutural no património cultural. Daí, uma tensão entre trivialização e desqualificação culturais, marcada por uma hipostatização da cultura, e a sua revitalização e desenvolvimento, inscritos em políticas de afirmação identitária. Se estas categorias fazem sentido, o debate não fica imune à apropriação da cultura pelo aceleracionismo tecnológico, perpetrador da sua reprodução em série. Sem que se subtraia o turismo à teologia negativa que acompanha a ‘autenticidade’, sugere-se uma interlocução mais estruturada com o seu modo de apropriação pela intermediação turística, tendo como primado a ideia de que ela reflete uma clássica abcessão de realismo, acentuada com a diluição contemporânea do monopólio da cultura.

Studies on the effects of light deprivation on the formation of adenosine 3’, 5’ -cyclic monophosphate
Creators: name: Nagy, Jim
Publisher: name: University of British Columbia
Year: 2010

description: Morphological, electrophysiological and biochemical changes have been shown to occur in the retina, lateral geniculate nucleus, and visual cortex of light deprived animals. We attempted to determine whether the dark-rearing of rats from birth to 15, 30 and 60 days of age alters the ability of noradrenaline (NA) 30 μM, potassium chloride (KCI) 50 μM, adenosine 30 μM and combinations of NA and KCI with adenosine to stimulate the _in vitro formation of cyclic AMP (cAMP) in visual cortical slices and, as an internal control, in frontal cortical slices. At 15 and 30 days of age there was an 11% and 2170 reduction, respectively, compared to normally reared controls, in the stimulation of cAMP formation in a 5 minute incubation with NA in both frontal and visual cortical slices. After 60 days of dark-rearing, however, this was reversed in that the NA stimulation of cAMP formation was 23% and 357» higher than controls in frontal and visual cortical slices. In frontal cortical slices of rats dark-reared for 15 and 30 days there was a significant reduction in the stimulation of cAMP formation in a 20 minute incubation with NA. No differences were observed between 30 day old experimental and control animals in studies of the accumulation of cAMP in frontal and visual cortical slices incubated for various times with KCI. The stimulation of cAMP formation induced by KCI and adenosine in a 5 minute incubation was 5770 and 397o higher, respectively, in frontal cortical slices of 60 day old experimental animals than controls while the response in visual cortical slices was unaffected. The differences found between 60 day old experimental and control animals were abolished in both visual and frontal cortical slices when adenosine was used in combination with NA or KCI. Studies of the accumulation of cAMP in slices incubated for various times with NA revealed that the effect observed in the visual cortex after 30 days of light deprivation was due to a decrease in the maximum level of cAMP reached within a 20 minute incubation period, whereas in the frontal cortex the maximum level attained within a 20 minute incubation period was unaffected. These results are discussed in terms of our present knowledge concerning supersensitivity and plasticity in the central nervous system and the role of cAMP in nerve.

description: The superconducting proximity effect is a long-standing topic of great importance in condensed matter physics. A crucial but unresolved issue is which interfacial and material details determine the efficiency of the proximity effect. In this work, we study an epitaxially grown superconductor (SC)/normal metal (NM) heterostructure (Pb/Ag) and find a spatially constant superconducting gap determined by local tunneling spectroscopy and magneto response measurements, despite the highly mismatched Fermi surfaces between individual Pb and Ag epitaxial layers, and the large differences in the lattice constants and electronic density of states in the separate components. The uniform superconducting gap is in contrast to the spatially varying pair potential with a discontinuity at the interface theoretically predicted for an ideal SC-NM junction and experimentally observed previously in several lateral SC-NM junctions. We experimentally verify that the transmission of electrons across the interface in the vertical Pb/Ag heterostructure is high enough that a new band structure emerges even at the single particle level. Our experimental results call for further theoretical work in order to develop predictive power for the proximity effect starting from realistic, material relevant microscopic models.

description: We provide a general and flexible approach to LIBOR modeling based on the class of affine factor processes. Our approach respects the basic economic requirement that LIBOR rates are non-negative, and the basic requirement from mathematical finance that LIBOR rates are analytically tractable martingales with respect to their own forward measure. Additionally, and most importantly, our approach also leads to analytically tractable expressions of multi-LIBOR payoffs. This approach unifies therefore the advantages of well-known forward price models with those of classical LIBOR rate models. Several examples are added and prototypical volatility smiles are shown. We believe that the CIR-process based LIBOR model might be of particular interest for applications, since closed form valuation formulas for caps and swaptions are derived.

description: The longitudinal spin-Seebeck eﬀect (SSE) in magnetic insulator|non-magnetic metal heterostruc- tures has been theoretically studied primarily with the assumption of an isotropic interfacial ex- change coupling. Here, we present a general theory of the SSE in the case of an antisymmetric Dzyaloshinskii-Moriya interaction (DMI) at the interface, in addition to the usual Heisenberg form. We numerically evaluate the dependence of the spin current on the temperature and bulk DMI using a pyrochlore iridate as a model insulator with all-in all-out (AIAO) ground state conﬁguration. We also compare the results of diﬀerent crystalline surfaces arising from diﬀerent crystalline orientations and conclude that the relative angles between the interfacial moments and Dzyaloshinskii-Moriya vectors play a signiﬁcant role in the spin transfer. Our work extends the theory of the SSE by includ- ing the anisotropic nature of the interfacial Dzyaloshinskii-Moriya exchange interaction in magnetic insulator|non-magnetic metal heterostructures and can suggest possible materials to optimize the interfacial spin transfer in spintronic devices.

description: Here we revisit the bag phenomenology of the deconfining phase transition to replenish it by introducing systematically the bag surface tension. Comparing the free energy of such bags and that one of the strings confining the static quark-antiquark pair, we express the string tension in terms of the bag surface tension and thermal pressure in order to estimate the bag characteristics using the lattice QCD data. Our analysis of the bag entropy density demonstrates that the surface tension coefficient is amazingly negative at the cross-over (continuous transition). This approach allows us to naturally account for an appearance of a very pronounced maximum (observed in the lattice QCD simulations) of the entropy of the bound static quark-antiquark pair. The vicinity of the (tri)critical endpoint is also analyzed to clarify the meaning of vanishing surface tension coefficient.

Type species: Epicoccum nigrum Link, Mag. Ges. Naturf. Freunde Berlin 7: 32 (1816).
Notes: Epicoccum was introduced by Link (1816) with the type species E. nigrum. This genus has 89 accepted species in Species Fungorum (Wang et al. 2023) but, the molecular data of most species were unavailable in Genbank database. Epicoccum species are often found on various plant materials as pathogens, saprobes or endophytes (Dzoyem et al. 2017, Jayasiri et al. 2017, Raza et al. 2019). The hyphomycetous anamorph of Epicoccum is characterized by having mono- to polyblastic, hyaline conidiogenous cells bearing globose to subglobose, brown, sometimes verruculose, dictyoconidia (Seifert & Gams 2011); while the coelomycetous anamorph is described by having fusiform or naviculate to oblong, hyaline conidia in pycnidial conidiomata (Chen et al. 2015). The sexual morph of Epicoccum is described by having conical globose to lenticular, ostiolate ascomata; branched, hyaline, cellular pseudoparaphyses; short-pedicellate, 8-spored asci, with an ocular chamber; cylindric-clavate ascospores with a gelatinous sheath (Jayasiri et al. 2017). The phylogenetic placement of Epicoccum spp. is demonstrated in figure 7.

description: O presente artigo propõe uma reflexão sobre o papel da viagem na sociedade contemporânea, com ênfase no aspecto relacional intrínseco à atividade turística. Para tanto, com base em uma revisão bibliográfica, serão abordadas e problematizadas questões como alteridade, reciprocidade, hospitalidade, à luz do processo de mercantilização da viagem na sociedade contemporânea. Uma das principais reflexões do artigo destaca a necessidade de uma ressignificação da viagem, a partir de atitudes de responsabilidade e respeito durante as trocas e os diálogos estabelecidos entre visitantes e visitados. Neste sentido, as férias devem ser ‘trabalhadas’ como um vetor de desenvolvimento e integração social e cultural. É a possibilidade da viagem contribuir com o fortalecimento da personalidade do indivíduo e de sua participação ativa na vida social e cultural da sociedade.

description: n this paper I introduce a new description of the crystal $B(Λ_0)$ of $\hat{\mathfrak{sl}_\ell}$. As in the Misra-Miwa model of $B(Λ_0)$, the nodes of this crystal are indexed by partitions and the $i$-arrows correspond to adding a box of residue $i$. I then show that the two models are equivalent by interpreting the operation of regularization introduced by James as a crystal isomorphism.

description: Multi-Processor SoC (MPSOC) design brings to the foreground a large number of challenges, one of the most prominent of which is the design of the chip interconnection.
With a number of on-chip blocks presently ranging in the tens, and quickly approaching the hundreds, the novel issue of how to best provide on-chip communication resources is clearly felt.
Scaling down of process technologies has increased process and dynamic variations as well as transistor wearout. Because of this, delay variations increase and impact the performance of the MPSoCs. The interconnect architecture inMPSoCs becomes a single point of failure as it connects all other components of the system together. A faulty processing element may be shut down entirely, but the interconnect architecture must be able to tolerate partial failure and variations and operate with performance, power or latency overhead.
This dissertation focuses on techniques at different levels of abstraction to face with the reliability and variability issues in on-chip interconnection networks. By showing the test results of a GALS NoC testchip this dissertation motivates the need for techniques to detect and work around manufacturing faults and process variations in MPSoCs’ interconnection infrastructure. As a physical design technique, we propose the bundle routing framework as an effective way to route the Network on Chips’ global links. For architecture-level design, two cases are addressed: (I) Intra-cluster communication where we propose a low-latency interconnect with variability robustness (ii) Inter-cluster communication where an online functional testing with a reliable NoC configuration are proposed. We also propose dualVdd as an orthogonal way of compensating variability at the post-fabrication stage. This is an alternative strategy with respect to the design techniques, since it enforces the compensation at post silicon stage.

description: As diferentes realidades e cenários latino-americanos são o resultado histórico de diversas raças, culturas, paisagens e vidas compartilhando o mesmo continente durante quinhentos anos, com suas glórias e lutas. A principal vertente cultural veio da Europa e mesclou-se com outras vertentes provenientes da África e outras já existentes na própria terra. A literatura, a política, as religiões e crenças, a história e a geografia, modelaram os limites e possiblidades contemporâneas desse enorme hub, dividido em 20 países, centenas de ilhas e milhares de cores, odores e sons. O turismo é igualmente resultado desse cadinho étnico-cultural.

description: We introduce an elementary way of constructing principal (Z_2)^m-bundles over compact smooth manifolds. In addition, we will define a general notion of locally standard (Z_2)^m-actions on closed manifolds for all m>0, and then give a general way to construct all such (Z_2)^m-actions from the orbit space. Some related topology problems are also studied.

Análise comparada das políticas públicas de turismo nos Governos de Getúlio Vargas (Brasil, 1930-1945) e Domingo Perón (Argentina, 1946-1951)

description: O presente trabalho busca promover um diálogo entre os saberes histórico e turístico, com o objetivo de investigar as políticas estatais de turismo dos Governos brasileiro e argentino, representados respectivamente por Getúlio Vargas e Domingo Perón, em meados do século XX. A metodologia utilizada baseia-se na pesquisa qualitativa, de natureza bibliográfica e documental, sob a perspectiva da comparação, tendo como fontes principais documentos produzidos no âmbito estatal, periódicos brasileiros e argentinos especializados em turismo, e jornais de ampla circulação. Respeitando-se as diferenças entre os dois regimes políticos, o turismo foi apropriado como um mecanismo de controle do tempo livre dos trabalhadores. Os diversos segmentos da sociedade civil, por sua vez, lidavam com o turismo de formas diferenciadas, e sua ação coletiva colaborou para o desenvolvimento do turismo nesses dois países no período e para o desenvolvimento das políticas nacionalistas de viés autoritário dos dois Governos.

description: We report magnetic penetration depth and thermal conductivity data for high-quality single crystals of BaFe$_2$(As$_{1-x}$P$_{x}$)$_2$ ($T_c=30$\,K) which provide strong evidence that this material has line nodes in its energy gap. This is distinctly different from the nodeless gap found for (Ba,K)Fe$_2$As$_2$ which has similar $T_c$ and phase diagram. Our results indicate that repulsive electronic interactions play an essential role for Fe-based high-$T_c$ superconductivity but that uniquely there are distinctly different pairing states, with and without nodes, which have comparable $T_c$.

description: Current and future weak lensing surveys will rely on photometrically estimated redshifts of very large numbers of galaxies. In this paper, we address several different aspects of the demanding photo-z performance that will be required for future experiments, such as the proposed ESA Euclid mission. It is first shown that the proposed all-sky near-infrared photometry from Euclid, in combination with anticipated ground-based photometry (e.g. PanStarrs-2 or DES) should yield the required precision in individual photo-z of sigma(z) < 0.05(1+z) at I_AB < 24.5. Simple a priori rejection schemes based on the photometry alone can be tuned to recognise objects with wildly discrepant photo-z and to reduce the outlier fraction to < 0.25% with only modest loss of otherwise usable objects. Turning to the more challenging problem of determining the mean redshift of a set of galaxies to a precision of 0.002(1+z) we argue that, for many different reasons, this is best accomplished by relying on the photo-z themselves rather than on the direct measurement of from spectroscopic redshifts of a representative subset of the galaxies. A simple adaptive scheme based on the statistical properties of the photo-z likelihood functions is shown to meet this stringent systematic requirement. We also examine the effect of an imprecise correction for Galactic extinction and the effects of contamination by fainter over-lapping objects in photo-z determination. The overall conclusion of this work is that the acquisition of photometrically estimated redshifts with the precision required for Euclid, or other similar experiments, will be challenging but possible.
