description: We study a uniform and isotropic cosmology with a decaying vacuum energy density, in the realm of a model with a time varying gravitational "constant". We show that, for late times, such a cosmology is in accordance with the observed values of the cosmological parameters. In particular, we can obtain the observed ratio between the matter density and the total energy density, with no necessity of any fine tuning.

description: Ecotopia, in collaboration with the Social Ecological Economic Development Studies (SEEDS) Program, decided to work on developing strategies to promote student participation in the Climate Action Plan 2030. To narrow the scope, we decided to focus on meat consumption. To examine if it is possible to reduce meat consumption and impact behavioural intentions using pro-environmental messaging, we conducted a between-subjects study at UBC Vancouver campus. We were interested in determining whether exposure to a gain frame message would be an effective nudge to reduce meat consumption. Participants were randomly assigned to one of three different conditions: a gain frame condition (exposure to positive and empowering messaging), a loss frame condition (exposure to an almost identical passage using negative and discouraging messaging), or a control condition (no exposure). We examined differences between responses of these groups regarding environmental concerns, perceived environmental impacts of meat consumption, and interest in environmental issues. Our analysis shows partial statistically significant differences between the three groups, which may be due to a fairly small sample size. However, the trends of the results revealed possible differences if there was a larger varied sample size or if we used different types of media, such as videos or posters. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: Sources of high frequency gravitational waves are reviewed. Gravitational collapse, rotational instabilities and oscillations of the remnant compact objects are potentially important sources of gravitational waves. Significant and unique information for the various stages of the collapse, the evolution of protoneutron stars and the details of the equations of state of such objects can be drawn from careful study of the gravitational wave signal.

We found a sum of 24 nests distributed in seven divisions: 86 (n = 2); 88 (n = 5); 91 (n = 2); 92 (n = 7); 97 (n = 5); 198 (n = 1); 416 (n = 2). Nests in divisions 86 and 88 were located in a part of the bank exposed to the sun in the morning and partially covered in the shade from a bus stop in the afternoon. Those in divisions 91, 92, and 97 were continuously exposed to sunlight all day, while in 198 and 416 were in banks predominantly covered by shadows from trees. The latter was on soil with higher humidity from dew. Females were active from November to March (late spring and summer). Circular statistics revealed a non-uniformly abundance distribution along the year, a significant seasonal pattern (n = 72 observations; p <0.05, Rayleigh (Z) test) was found with the mean vector in December (Table 1; Fig. 2A). Males were observed only in December 2018, flying over the nest sites, but no mating behavior was observed.
 Nest excavations by the wasps stopped around 1 PM, then each female stayed in its respective nest and exhibited guard behavior, with the following female patterns: (i) closing the nest entrance with its head; (ii) exposing its head outside the entrance and opening its jaws whenever another individual (same species or not) appeared near the nest. Defense behavior (iii) occurred more frequently against T. taschenbergi females that tried to enter the nest and then immediately retreated, without conflict. No evidence of two or more females sharing the same nest was observed. Foraging and provisioning activities were observed from November until March. In one case, a female left the nest and returned more than 30 minutes later with a prey. In total, we sampled seven prey items, six workers and one drone of the stingless bee Trigona spinipes (Fabricius, 1793).

description: Time-optimal control for high-order chain-of-integrator systems with full state constraints remains an open and challenging problem within the discipline of optimal control. The behavior of optimal control in high-order problems lacks precise characterization, and even the existence of the chattering phenomenon, i.e., the control switches for infinitely many times over a finite period, remains unknown and overlooked. This paper establishes a theoretical framework for chattering phenomena in the considered problem, providing novel findings on the uniqueness of state constraints inducing chattering, the upper bound of switching times in an unconstrained arc during chattering, and the convergence of states and costates to the chattering limit point. For the first time, this paper proves the existence of the chattering phenomenon in the considered problem. The chattering optimal control for 4th-order problems with velocity constraints is precisely solved, providing an approach to plan time-optimal snap-limited trajectories. Other cases of order $n\leq4$ are proved not to allow chattering. The conclusions rectify a longstanding misconception in the industry concerning the time-optimality of S-shaped trajectories with minimal switching times.

Multiphoton entanglement through a Bell multiport beam splitter

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)

description: Multiphoton entanglement is an important resource for linear optics quantum computing. Here we show that a wide range of highly entangled multiphoton states, including W-states, can be prepared by interfering single photons inside a Bell multiport beam splitter and using postselection. A successful state preparation is indicated by the collection of one photon per output port. An advantage of the Bell multiport beam splitter is that it redirects the photons without changing their inner degrees of freedom. The described setup can therefore be used to generate polarisation, time-bin and frequency multiphoton entanglement, even when using only a single photon source.

description: Using results on the mass gap in the sine-Gordon model combined with the exact amplitudes in the bosonized representation of the Heisenberg spin-1/2 chain and one-loop renormalization group, we derive a quantitative expression for the gap in a dimerized spin-1/2 chain. This expression is shown to be in good agreement with recent numerical estimates when a marginally irrelevant perturbation is taken into account.

Os Cadernos BAD tem sido tudo isto, desde 1963, quando ainda publicados em Coimbra, e pelo reconhecimento dessa importante função enquanto veiculo de resposta a necessidades objetivas de divulgação e de transmissão de ideias e experiencias entre os profissionais de informação que a Associação Portuguesa de Bibliotecários, Arquivistas e Documentalistas continua a encarar a sua publicação como uma prioridade estratégica e como um compromisso para com os seus associados e para com a comunidade de profissionais em geral. Com o evoluir da profissão, a transdisciplinaridade impôs-se ao nível da diversidade temática e de abordagem do leque de artigos propostos em cada número. Na mesma medida, o reconhecimento internacional dos Cadernos BAD exerceu uma crescente atraccão em autores não nacionais, com evidente destaque dos falantes da língua portuguesa e, muito expressivamente, de autores brasileiros. O numero que agora apresentamos e bem elucidativo dessas dinâmicas, e esperamos que a sua leitura contribua para o objectivo ultimo de valorização cientifica, técnica e cultural que se pretende.

Ao longo das dezenas de números publicados, foi mantida uma postura de acompanhamento de novos temas emergentes na profissão e de abertura a abordagens plurais, num esforço de aproximação e comunicação entre profissionais BAD e de outros sectores afins, que de resto comprova a transversalidade e a relevância social da Informação e Documentação. Aberta à colaboração espontânea de profissionais, investigadores, docentes ou estudantes, nacionais ou estrangeiros, associados ou não, a revista vive necessariamente do espírito de partilha de conhecimentos, de experiências e de boas práticas, do ritmo e da qualidade dos contributos, e do empenho de uma Comissão Editorial que analisa, avalia e delibera sobre a publicação dos materiais recebidos. Num país em que não abundam nem a oferta editorial nem os canais para a comunicação e divulgação de textos da nossa área, seria de esperar um considerável número de propostas de artigos para publicação, o que a realidade não tem confirmado. Mais do que falta de condições para a investigação, do que insipiência do corpo de investigadores nacionais ou do que escassez de projectos em curso, parece-nos antes haver um défice ao nível de uma cultura de comunicação de resultados. Comunicação essa que, é nossa convicção, constitui um dos pilares para o desenvolvimento da profissão e para a consolidação e reconhecimento da Informação e Documentação como Ciência. Esperamos que o conjunto de artigos que integram o presente número contribua para esse objectivo.

When varying the doping from a non-superconducting film (x = 0.11) to a superconducting overdoped film (x = 0.17), we observe, up to optimal doping (x = 0.15), a partial gap opening. A model combining a spin density wave gap and a frequency and temperature dependent self energy reproduces our data reasonably well. The magnitude of this gap extrapolates to zero for x ~ 0.17 indicating the coexistence of magnetism and superconductivity in this material and the existence of a quantum critical point at this Ce concentration.

Realizou-se também um exercício, utilizando-se a metodologia de Pejtersen – “Dimensões da Ficção” – para indexação daquele tipo de literatura, confrontando-se os resultados com categorização baseada na leitura pelos usuários. Os resultados demonstram que indexadores tendem a procedimentos semelhantes aos utilizados com a literatura não-ficcional, mas exigindo especificidades, como: leitura integral do texto; habilidade em reconhecer estilos ⁄ gêneros literários e recursos gráficos e linguísticos. Sugere-se a renomeação de uma das categorias de Pejtersen.

description: Utilizing the realistic continuum description of twisted bilayer MoTe2 and many-body exact diagonalization calculation, we establish that the second moiré band of twisted bilayer MoTe2, at a small twist angle of approximately 2°, serves as an optimal platform for achieving the long-sought non-Abelian fractional quantum anomalous Hall states without the need for external magnetic fields. Across a wide parameter range, our exact diagonalization calculations reveal that the half-filled second moiré band demonstrates the ground state degeneracy and spectral flows, which are consistent with the pfaffian state in the first Landau level. We further elucidate that the emergence of the non-Abelian state is deeply connected to the remarkable similarity between the second moiré band and the first Landau level. Essentially, the band not only exhibits characteristics akin to the first Landau level, $\frac{1}{2π}\int_\mathrm{BZ}\mathrm{d}^2\mathbf{k}\:\mathrm{tr}\:η(\mathbf{k}) \approx 3$ where $η_{ab}(\mathbf{k})$ is the Fubini-Study metric of the band, but also that its projected Coulomb interaction closely mirrors the Haldane pseudopotentials of the first Landau level. Motivated from this observation, we introduce a novel metric of "first Landau level"-ness of a band, which quantitatively measures the alignment of the projected Coulomb interaction with the Haldane pseudopotentials in Landau levels. This metric is then compared with the global phase diagram of the half-filled second moiré band, revealing its utility in predicting the parameter region of the non-Abelian state. In addition, we uncover that the first and third moiré bands closely resemble the lowest and second Landau levels, revealing a remarkable sequential equivalence between the moiré bands and Landau levels. We finally discuss the potential implications on experiments.

description: Given two complete atomistic lattices L_1 and L_2, we define a set S(L_1,L_2) of complete atomistic lattices by means of three axioms (natural regarding the description of separated quantum compound systems), or in terms of a universal property with respect to a given class of bimorphisms. We call the elements of S(L_1,L_2) weak tensor products of L_1 and L_2. We prove that S(L_1,L_2) is a complete lattice. We compare the bottom element with the separated product of Aerts and with the box product of Graetzer and Wehrung. Similarly, we compare the top element with the tensor products of Fraser, Chu and Shmuely. With some additional hypotheses on L_1 and L_2 (true for instance if L_1 and L_2 are moreover irreducible, orthocomplemented and with the covering property), we characterize the automorphisms of weak tensor products in terms of those of L_1 and L_2.

In addition to interface-tracking capabilities that include tracking of two fluid phases, an implementation of a Subgrid-Scale (SGS) modeling framework for increased accuracy when simulating sharp boundary layers is enclosed. The SGS modeling framework simplifies embedding subgrid-scale profiles into the unstructured Finite Volume discretization. Our design of the SGS model library significantly simplifies adding new SGS models and applying SGS modeling to Partial Differential Equations (PDEs) in OpenFOAM.

Infrared spectroscopy of a brown dwarf companion candidate near the young star GSC 08047-00232 in Horologium

description: We present infrared H- and K-band spectra of a companion candidate 3" north of the young star GSC 08047-00232, a probable member of the nearby young Horologium association. From previously obtained JHK-band colors and the magnitude difference between primary and companion candidate, the latter could well be substellar (Neuh"auser et al. 2003) with the spectral type being roughly M7-L9 from the JHK colors (Chauvin et al. 2003). With the H- and K-band spectra now obtained with ISAAC at the VLT, the spectral type of the companion candidate is found to be M6-9.5. Assuming the same age and distance as for the primary star (~35 Myrs, 50 to 85 pc), this yields a mass of ~25 Jupiter masses for the companion, hence indeed substellar. After TWA-5 B and HR 7329 B, this is the third brown dwarf companion around a nearby (up to 100 pc) young (up to 100 Myrs) star. A total of three confirmed brown dwarf companions (any mass, separation above 50 AU) around 79 stars surveyed in three young nearby associations corresponds to a frequency of 6 \pm 4 % (with a correction for missing companions which are almost on the same line-of-sight as the primary star instead of being separated well), consistent with the expectation, if binaries have the same mass function as field stars. Hence, it seems that there is no brown dwarf desert at wide separations.

Creators: name: Young, David
Publisher: name: The Open University
Year: 1989

description: This thesis looks at the Anglican theologian Frederick Denison Maurice (1805-72) in the light of Unitarianism, the religious background of his family, with an historical introduction tracing Unitarianism from C.I7OO-I85O. Five biographical perspectives examine (i) Maurice's childhood, suggesting that his concern with the Fatherhood of Cod, opposition to the penal substitutionary view of the atonement and rejection of original sin are derived from his father's influence; (ii) his progress towards Anglicanism and emotional needs expressed in his novel Eustace Conway; (iii) Maurice's response to Romanticism, indebtedness to the Creek Fathers, the influence of S T Coleridge, Thomas Erskine, and Robert Hall; (iv) friendships with Unitarians, especially Henry Solly; (v) work in London as hospital chaplain, Christian Socialist and educationist. Part Three looks at aspects of Maurice's theology and assesses debt to Unitarianism. His teaching was undergirded by belief in Cod as a loving Father; there was a life-long search for human unity grounded in the unity of Cod; a view of atonement stressing Christ's eternal union with the Father and mankind; humanity seen in Christ, but drawing on the Unitarian insistence on the potential of all human life; and a concept of eternal life which precluded dogmatic statements as to the fate of the wicked. Maurice's teaching on the church, sacraments and ministry is compared with the mid-nineteenth century Unitarian position. Maurice perceived the Church of England in terms so personal that Unitarians wondered how he could remain an Anglican, but the central place Maurice gave to Christ as executant of the Father s Will and Head and Centre of humanity meant Unitarianism was not an option. Maurice is a channel for a Unitarian contribution to contemporary thinking on incarnation, the nature of Cod, and inter-faith relations.

Accelerating cosmologies from M/String theory compactifications

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We point out that the solution of $(4+n)$-dimensional gravity coupled to the dilaton and an $n$-form field strength can give rise to a flat 4-dimensional universe (with a scale factor) of the type proposed recently under time dependent compactifications. The compact internal spaces could be hyperbolic, flat or spherical and the solution is identical to the space-like two brane or S2-brane. As has been shown previously for SM2 solution with a fixed field strength we show that for $n=7$ (where the dilaton is vanishing and with a general field strength), 6 the corresponding SM2 and SD2 solutions can give accelerating cosmologies in Einstein frame for both hyperbolic and flat internal spaces, thereby meeting the challenge of obtaining such a solution from M/String theory compactifications.

description: Biodiversity is an important component of healthy ecosystems, and thus understanding the mechanisms behind species coexistence is critical in ecology and conservation biology. In particular, few studies have focused on the dynamics resulting from the co-occurrence of mutualistic and competitive interactions within a group of species. Here we build a mathematical model to study the dynamics of a guild of competitors who are also engaged in mutualistic interactions with a common partner. We show that coexistence as well as competitive exclusion can occur depending on the competition strength and on strength of the mutualistic interactions, and we formulate concrete criteria for predicting invasion success of an alien mutualist based on propagule pressure, alien traits (such as its resource exchange ability) and composition of the recipient community. We find that intra guild diversity promotes the coexistence of species that would otherwise competitively exclude each other, and makes a guild less vulnerable to invasion. Our results can serve as a useful framework to predict the consequences of species manipulation in mutualistic communities.
Do projecto PCM – Plataforma Comum de Modernização, à Macro-estrutura de Classificação de Documentos para a Administração Pública: reflexões

description: O projecto PCM (Plataforma Comum de Modernização) aprovado pelo POAP envolveu diversas Secretarias-Gerais, do Ministério das Finanças e Administração Pública, da Administração Interna, do Ambiente e Desenvolvimento Rural e ainda o Instituto da Juventude, o CEGER e o Instituto dos Arquivos Nacionais/Torre do Tombo. O projecto visou objectivos amplos de modernização, nomeadamente do ponto de vista da interoperabilidade semântica, técnica e organizacional. Visou a desmaterialização de documentos e a troca de documentos electrónicos entre diversas entidades. Dando expressão à interoperabilidade semântica foi definida uma linguagem de classificação de documentos baseada nas funções e subfunções transversais da administração pública, a que foi dado o nome de Macro estrutura Temática Áreas - Meio. Levando mais longe os objectivos do projecto, cada parceiro tinha que definir internamente as suas próprias funções e subfunções a serem aprovadas pelo Grupo de Trabalho então constituído no âmbito do projecto, para que de modo coordenado garantissem a mesma lógica da estrutura classificativa inicial. As reflexões que aqui deixamos partem do pressuposto que os grandes objectivos do projecto podem ficar comprometidos, porque limitados ao número dos parceiros intervenientes, pois só podem ser de facto atingidos caso haja continuidade e desenvolvimento da macroestrutura classificativa alargada a todos os ministérios, abrangendo todo o espectro das funções do Estado, espelhadas então na linguagem comum de classificação de documentos que o projecto apenas iniciou.

Hadron attenuation in deep inelastic lepton-nucleus scattering

description: We present a detailed theoretical investigation of hadron attenuation in deep inelastic scattering (DIS) off complex nuclei in the kinematic regime of the HERMES experiment. The analysis is carried out in the framework of a probabilistic coupled-channel transport model based on the Boltzmann-Uehling-Uhlenbeck (BUU) equation, which allows for a treatment of the final-state interactions (FSI) beyond simple absorption mechanisms. Furthermore, our event-by-event simulations account for the kinematic cuts of the experiments as well as the geometrical acceptance of the detectors. We calculate the multiplicity ratios of charged hadrons for various nuclear targets relative to deuterium as a function of the photon energy nu, the hadron energy fraction z_h=E_h/nu and the transverse momentum p_T. We also confront our model results on double-hadron attenuation with recent experimental data. Separately, we compare the attenuation of identified hadrons (pi^\pm, π^0, K^\pm, p and pbar) on Ne and Kr targets with the data from the HERMES Collaboration and make predictions for a Xe target. At the end we turn towards hadron attenuation on Cu nuclei at EMC energies. Our studies demonstrate that (pre-)hadronic final-state interactions play a dominant role in the kinematic regime of the HERMES experiment while our present approach overestimates the attenuation at EMC energies.

Archboldia papuensis sanfordi Mayr and Gilliard, 1950: 1 (southwestern slope of Mount Hagen, 4 miles west of Tomba, Central Highlands, Mandated Territory of New Guinea; altitude 8500 feet).
Now Archboldia papuensis sanfordi Mayr and Gilliard, 1950. See Mayr and Gilliard, 1954: 362–363, pl. 13; Gilliard, 1969: 281–293; Coates, 1990: 385–391; and Frith and Frith, 2004: 300– 302; 2009a: 396.
HOLOTYPE: AMNH 348448, adult male, collected on the southwestern slope of Mount Hagen, 05.52S, 144.13E (Frith and Beehler,1998: 569), 4 mi. west of Tomba (= 5 mi. west of Base Camp, as on label), 8500 ft, Western Highlands Province, Papua New Guinea (formerly the Central Highlands of the Mandated Territory of New Guinea), on 18 July 1950, by E. Thomas Gilliard.
COMMENTS: The AMNH number of the holotype was cited in the original description and measurements were given for three adult males and one adult female. As mentioned in the original description, Gilliard was allowed by the Australian authorities to bring these four specimens to the AMNH on his return, the remainder of the specimens of this form being shipped with the rest of his 1950 collection. Using the measurements given, I was unable to determine which three specimens are paratypes. A total of 11 specimens were collected, with the 10 in addition to the holotype cataloged as AMNH 705703– 705707, 705707bis, 705708–705711, six adult males, one immature male, two females, one female?, near Base Camp, Mount Hagen, 8500–10,000 ft., 12–22 July 1950. AMNH 705708 was sent to AM in 1953. See Mayr and Gilliard (1954) for a report on the collections made on Gilliard’s 1950 and 1952 expeditions.

On the viability of the Palatini form of 1/R gravity

description: Recently Flanagan [astro-ph/0308111] has argued that the Palatini form of 1/R gravity is ruled out by experiments such as electron-electron scattering. His argument involves adding minimally coupled fermions in the Jordan frame and transforming to the Einstein frame. This produces additional terms that are ruled out experimentally. Here I argue that this conclusion is false. It is well known that conformally related theories are mathematically equivalent but not physically equivalent. As discussed by Magnano and Sokolowski [2] one must decide, in the vacuum theory, which frame is the physical frame and add the minimally coupled Lagrangian in this frame. If this procedure is followed the resulting theory is not ruled out experimentally. The discussions in this paper also show that the equivalence between the generalized gravitational theories and scalar tensor theories discussed by Flanagan [gr-qc/0309015] is only mathematical, not physical.
