 Hesperoctenes vicinus Jordan, 1922: 210-211.
 Material examined: Misiones: Parque Provincial Cañadón de Profundidad, 27°33′S, 55°42′W, 03.iii.2010, 1 ♀ (CMLA 774) on Molossops temminckii ♀ (FMI 182).
 Identification: This species is characterized by patches or rows of bristles on the medial posterior margin of the underside of the head. The gular crest is defined by an irregular double row of six to eight bristles on the middle of the hind margin. Antennal segments I and III are equal in length, and the labrum is proportionally three times wider than long. The bristles located on other parts of the body are sparse and distributed irregularly,including numerous bare areas on the pronotal disk.The species is similar to H. cartus, but has more bristles with the exception of the gular marginal row, which contains fewer bristles than in H. cartus, and the second antennal segment is shorter (Jordan, 1922; Ronderos, 1962a, b).
 Comments: This species was previously known only from Paraguay,reported on Molossus rufus (= M.ater; Ueshima, 1972) and from Argentina on Molossops temminckii. Here its distribution in Argentina is extended quite far east, reaching the province of Misiones. Previously, it was known only from Jujuy and Salta on M. temminckii (Autino et al., 2009, 2016).

description: An econometric model, measuring the impact of market forces and Government policies on demand and prices for U.S. sorghum during 1959/81, is estimated. The model shows that domestic feed demand is less responsive to a price change than is export demand. Corn's substitution for sorghum as a feed has further eroded the sorghum market. Today's sorghum industry faces surplus conditions similar to those of the sixties. Simulation with the model indicates earnings will be weak unless Government programs change or carryover stocks are drawn down.

description: O estudo tem por objetivo elaborar um panorama geral dos repositórios de dados de pesquisa na área das ciências da saúde. Para tanto, foi realizada uma pesquisa descritiva, na qual foram analisados vinte repositórios de dados cadastrados e certificados no diretório re3data.org. A análise metodológica foi desenvolvida a partir das características essenciais apontadas por Rodrigues et al. (2010) para um repositório de dados, que foram sistematizadas em categorias. As categorias exploram aspectos acerca do armazenamento, descrição e apresentação dos itens. Os resultados do estudo indicam que os repositórios analisados se encontram em diferentes estados de desenvolvimento. No entanto, foi possível observar que não existe tendência para o uso de software de repositório específico, embora haja tendência estruturada para o padrão de metadados e os tipos de recursos disponibilizados. De forma geral, grande parte dos repositórios analisados possuem características de repositórios de acesso aberto, no entanto apenas 30% deles distribuem seus conteúdos acompanhados de licenças abertas. Percebe-se, portanto, uma incipiente e crescente preocupação com o desenvolvimento de sistemas dessa natureza.

Beam deconvolution in noisy CMB maps
Creators: name: Burigana, Carlo

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The subject of this paper is beam deconvolution in small angular scale CMB experiments. The beam effect is reversed using the Jacobi iterative method, which was designed to solved systems of algebraic linear equations. The beam is a non circular one which moves according to the observational strategy. A certain realistic level of Gaussian instrumental noise is assumed. The method applies to small scale CMB experiments in general (cases A and B), but we have put particular attention on Planck mission at 100 GHz (cases C and D). In cases B and D, where noise is present, deconvolution allows to correct the main beam distortion effect and recover the initial angular power spectrum up to the end of the fifth acoustic peak. An encouraging result whose importance is analyzed in detail. More work about deconvolution in the presence of other systematics is in progress. This paper is related to the Planck LFI activities.

description: In this paper, we introduce Bar-Natan homology for null homologous links in \mathbb{RP}^3 over the field of two elements. It is a deformation of the Khovanov homology in \mathbb{RP}^3 defined by Asaeda, Przytycki and Sikora. We also define an s-invariant from this deformation using the same recipe as for links in S^3, and prove some genus bound using it. The key ingredient is the notion of twisted orientation for null homologous links and cobordisms in \mathbb{RP}^3.

Properties of low-lying excited manifolds in the Mn12 acetate

description: Most experimental data on the single-molecule magnet Mn$_{12}$ acetate have been successfully explained by the assumption that the Mn$_{12}$ acetate has an effective ground-state spin of S=10. However, the effect of the low-lying excited manifolds caused by interactions between Mn spins has not been well understood. To investigate the features of the low-lying excited manifolds, the intramolecular exchange interactions are calculated using density-functional theory (DFT). With the calculated exchange parameters, the energy gap between the S=10 ground-state and the first excited-state manifold is calculated by diagonalization of the Heisenberg Hamiltonian. The upper limit on the energy gap is about 40.5 K which is likely to be overestimated due to incomplete treatment of the Coulomb potential within DFT. It is found that there are several S=9 low-energy excited-state manifolds above the S=10 ground-state manifold. The magnetic anisotropy barriers for the low-lying spin excitations are calculated using DFT. Based on the calculations, it is found that the anisotropy barriers for the low-lying excited manifolds are approximately the same as that for the ground-state manifold, which is applicable to other single-molecule magnets such as Mn$_4$.
Propagators in AdS for higher-derivative and nonlocal gravity: Heat kernel approach

description: We present a new covariant method of construction of the (position space) propagators in the $N$-dimensional (Euclidean) anti-de Sitter background for any gravitational theory with the Lagrangian that is an analytic expression in the metric, curvature, and covariant derivative. We show that the propagators (in Landau gauge) for all such theories can be expressed using the heat kernels for scalars and symmetric transverse-traceless rank-2 tensors on the hyperbolic $N$-space. The latter heat kernels are constructed explicitly and shown to be directly related to the former if an improved bi-scalar representation is used. Our heat kernel approach is first tested on general relativity, where we find equivalent forms of the propagators. Then it is used to obtain explicit expressions for propagators for various higher-derivative as well as infinite-derivative/nonlocal theories of gravity. As a by-product, we also provide a new derivation of the equivalent action (correcting a mistake in the original derivation) and an extension of the quadratic action to arbitrary ${N\geq 3}$ dimensions.

description: The remnant of a neutron star binary coalescence is expected to be temporarily stabilised against gravitational collapse by its differential rotation. We explore the possibility of dynamo activity in this remnant and assess the potential for powering a short-duration gamma-ray burst (GRB). We analyse our three-dimensional hydrodynamic simulations of neutron star mergers with respect to the flow pattern inside the remnant. If the central, newly formed super-massive neutron star remains stable for a good fraction of a second an efficient low-Rossby number $α-Ω$-dynamo will amplify the initial seed magnetic fields exponentially. We expect that values close to equipartition field strength will be reached within several tens of milliseconds. Such a super-pulsar could power a GRB via a relativistic wind, with an associated spin-down time scale close to the typical duration of a short GRB. Similar mechanisms are expected to be operational in the surrounding torus formed from neutron star debris.

description: Beetles (Coleoptera) are a critical component of terrestrial ecosystems filling numerous ecological roles. Soil-dwelling beetles play an important role in pedogenesis through the production of biogenic structures throughout their life cycle. Given their life habits, beetle trace fossils should be abundant in the fossil record and a number of ichnotaxa have been attributed to beetles, yet there is still much to learn about their trace-making techniques and the variety of morphologies of traces they can produce throughout their life cycle. The Tenebrionidae (darkling beetles) is a common, globally distributed group that includes many soil-dwelling species from a variety of environments. The purpose of this project was to gain a better understanding of biogenic structures produced during each life stage of two species of burrowing darkling beetles, Zophobas morio F. and Tenebrio molitor L. Single to multiple specimens of each species were placed in variably sized enclosures filled with massive and layered sediment with and without layers of food. Biogenic structures produced by the two species were similar, but distinct between each life stage and associated with different behaviors. Observed biogenic structures are comparable to Palaeophycus, Planolites, Fictovichnus, Rebuffoichnus, Pallichnus, Taenidium, Skolithos, and Conichnus depending on the life stage. Neoichnological studies such as this can aid in the understanding of biogenic structures in the fossil record. Being able to effectively link continental traces to trace makers will ultimately improve our understanding of the composition of ancient terrestrial ecosystems.

description: SeeRRI project has the overall objective of establishing a foundation for building self-sustaining R&I ecosystems in Europe. In doing this, the WP2 (Active mapping of SeeRRI territorial R&I ecosystems and the inclusion of RRI) has a strategic relevance since it is the occasion to map and extract knowledge from the selected SeeRRI territories in order to understand the current situation of the R&I ecosystems and to define a basic framework for integrating RRI approach into regional development policies. The basis for the definition of a common procedure for actively mapping R&I ecosystems and stakeholders is presented in the Deliverable 2.1 – Report on procedures and guidelines for active mapping. The mapping procedure is divided into two complementary parts: the ‘quantitative mapping’ (T2.2) and the ‘qualitative mapping’ (T2.3). The present Deliverable 2.3 – RRI within regional development policies: the case of Catalonia, Lower Austria and Nordland describes in detail the ‘qualitative mapping’ methodology and the results of its application to the 3 SeeRRI territories.

description: Here we present a new protocol for controlled quantum key agreement and another protocol for key agreement with a specific focus on the security analysis. Specifically, detailed security proof is provided against impersonated fraudulent attack and collective attacks and it is established that the proposed protocols are not only secure, but they also satisfy other desired properties of such schemes (i.e., fairness and correctness). Further, the proposed schemes are critically compared with a set of schemes for quantum key agreement and an existing scheme for controlled quantum key agreement (Tang et al.'s protocol) in terms of efficiency and the required quantum resources. Especially, it is observed that in contrast to the existing schemes, the present scheme does not require quantum memory. In addition, the protocol for controlled quantum key agreement proposed here is found to require quantum resources (Bell state and single photon state) that are easier to produce and maintain compared to the quantum resources (GHZ states) required by the only known existing protocol for the same purpose, i.e., Tang et al.'s protocol.

description: A ciência envolve hoje um conjunto de procedimentos que não se esgotam no manuseamento de métodos e técnicas, materiais e enquadramentos teóricos. A preocupação de muitos cientistas reside na visibilidade científica do seu trabalho, pela valorização pessoal ou progressão na carreira, entre outros motivos. De braço dado com uma “novilíngua” muito própria (Martins, 2012), a ciência passou a estar na encruzilhada de rankings, visualizações, downloads, citações, bases de indexação de revistas, projetos e bolsas, ou da internacionalização. Na expectativa de contribuir para uma reflexão sobre a disseminação do trabalho científico, este texto tenta responder a dois desafios: 1) recuperar algum do debate conceptual sobre o que significa informar/comunicar sobre ciência (Wolton, 2009; Carvalho & Cabecinhas, 2004), propondo a complementaridade entre os dois conceitos, em que o primeiro trata a publicação de conteúdos científicos e o segundo sugere uma vertente relacional entre investigadores e públicos (não) especializados; 2) analisar a informação e as ações de comunicação de ciência de centros de investigação em Portugal. Pretende-se caracterizar o posicionamento destes centros em ambientes online (site, blogues, redes sociais, etc.), avaliando questões críticas como modos de atuação nestes contextos, conteúdos habitualmente publicados, ações de formação com grupos específicos, relação com os média, interação com repositórios institucionais.

description: The one-loop quantum corrections to the mass and central charge of the N=2 vortex in 2+1 dimensions are determined using supersymmetry-preserving dimensional regularization by dimensional reduction of the corresponding N=1 model with Fayet-Iliopoulos term in 3+1 dimensions. Both the mass and the central charge turn out to have nonvanishing one-loop corrections which however are equal and thus saturate the Bogomolnyi bound. We explain BPS saturation by standard multiplet shortening arguments, correcting a previous claim in the literature postulating the presence of a second degenerate short multiplet at the quantum level.

title: Nitrogen Isotopic Variation in Irons and Other Fe-Ni Metal Rich Meteorites
Creators: name: Franchi, Ian
Publisher: name: The Open University
Year: 1988

description: An investigation of the nitrogen concentration, its distribution, location and isotopic composition in iron meteorites and the anomalous metal-rich mesosiderite Bencubbin has been undertaken with the use of a high sensitivity mass spectrometer. Existing stepped heating extraction systems were modified for the types of material analysed in this study and a laser microprobe technique was developed for the purpose of analysing well characterised sample areas of the Bencubbin meteorite with high spatial resolution. The irons display a range in values which is to too large to be the result of fractionation processes in the nebula. An explanation involving primordial heterogeneity is favoured, with the iron meteorite parent bodies having sampled at least four isotopically distinct nitrogen reservoirs. One of the factors controlling the variation may be an input of 1%-rich nitrogen, together with 26Al, from a nova event prior to solar nebula collapse. The behaviour of nitrogen during core formation processes is also considered and compared with the observed nitrogen variation in the non-magmatic group lAB. Other secondary processes affecting nitrogen in the iron meteorites are also identified. The isotopic composition of nitrogen has been used to identify genetic links between iron and stony meteorites, thereby enhancing the normal technique based on oxygen isotopic composition (prohibited by the rarity of oxygen bearing minerals). A second factor influencing the primordial nitrogen isotopic variability has been identified in the unusual polymict breccia Bencubbin. This meteorite contains two nitrogen components, Na and Np, with a value = +1000%o (twice the content of atmospheric nitrogen), present in the metal clasts and probably in the silicate clasts and matrix also. The carrier phase of Na appears to be a chromium-rich sulphide ((Cro.67» ^60,33)283) with a structure similar to pseudo-hexagonal pyrrhotite, containing sulphur slightly depleted in Np may be associated with carbon showing a small enrichment of The data gathered so far indicate that these components formed from a supernova.

description: The definition of subshifts of finite symbolic rank is motivated by the finite rank measure-preserving transformations which have been extensively studied in ergodic theory. In this paper we study subshifts of finite symbolic rank as essentially minimal Cantor systems. We show that minimal subshifts of finite symbolic rank have finite topological rank, and conversely, every minimal Cantor system of finite topological rank is either an odometer or conjugate to a minimal subshift of finite symbolic rank. We characterize the class of all minimal Cantor systems conjugate to a rank-$1$ subshift and show that it is dense but not generic in the Polish space of all minimal Cantor systems. Within some different Polish coding spaces of subshifts we also show that the rank-1 subshifts are dense but not generic. Finally we study topological factors of minimal subshifts of finite symbolic rank. We show that every infinite odometer and every irrational rotation is the maximal equicontinuous factor of a minimal subshift of symbolic rank $2$, and that a subshift factor of a minimal subshift of finite symbolic rank has finite symbolic rank.

We qualitatively reproduce the features of quark-hadron duality for all potentials considered, and discuss similarities and differences to previous models that simplified the situation by treating either the quarks or all particles as scalars. We discuss the scaling results for PWIA and FSI, and the approach to scaling using the analog of the Callan-Gross relation for y-scaling.

description: A measure of the correlation between two earthquakes is used to link events to their aftershocks, generating a growing network structure. In this framework one can quantify whether an aftershock is close or far, from main shocks of all magnitudes. We find that simple network motifs involving links to far aftershocks appear frequently before the three biggest earthquakes of the last 16 years in Southern California. Hence, networks could be useful to detect symptoms typically preceding major events.

description: Toda pesquisa científica é pautada no levantamento, elaboração e análise de dados que geram conteúdos científicos. Com a finalidade de dar visibilidade a esta questão, a disponibilização dos dados de pesquisa tem ganhado cada vez mais notoriedade dentro da comunidade científica. E como agente da comunicação científica, algumas revistas já têm apoiado e incentivado o compartilhamento de dados como requisito para publicação. Diante desse cenário, este estudo buscou analisar a proporção e a forma como as revistas em acesso aberto das áreas de Ciências e Medicina do Brasil e de Portugal indexadas no DOAJ têm tratado a questão do depósito e publicação dos dados. Como resultado, percebeu-se que, mesmo que de forma ainda discreta, as revistas brasileiras e portuguesas de acesso aberto têm se mobilizado para que os dados estejam à disposição da comunidade de forma completa e acessível. Conclui-se que a maioria das publicações que exigem ou sugerem que os dados sejam disponibilizados reconhecem a importância do acesso ao conteúdo completo das pesquisas.

description: A left-right model of quarks and leptons based on the gauge group $SU(3)_c \times SU(2)_L \times SU(2)_R \times U(1)_{B-L}$ is studied. Here the scalar sector consists of only two doublets namely (1,2,1,1) and (1,1,2,1) but familiar bidoublet (1,2,2,0) is removed. Quarks and charged leptons get mass from a single see-saw mechanism but neutrinos get mass from a double see-saw mechanism. In this type of models the heaviest right handed neutrino can be of order $10^{13}$ GeVs or less in a natural way, depending on the size of related Yukawa couplings.

description: The harmonic oscillations of a spring-ball model of benzene-like nanosystems with Hooke's law interactions between nearest, second, and third neighbors are explored. We show that in the cylindrical coordinates the dynamics of this cyclic hexagonal system is described by the Lagrange equations similar to those of the one-dimensional two-component crystal model. We expose that the vibration frequencies of the hexagonal model lie on the branches of the dispersion law of the associated lattice model, and their positions are determined by the cyclic Born-Von Karman condition. The hexagonal model is generalized to one describing the benzene molecule and the fully deuterated and halogenated benzenes. The effect of hybridization of vibration modes and the pushing apart of spectral branches in the crossover situation is revealed. All the discrete frequency spectrum and normal modes of oscillations and their explicit dependencies on all the constants of elastic interactions are exactly found.

description: As society is recognizing the presence of the climate crisis, zero waste initiatives are of utmost importance for the University of British Columbia to implement. As per UBC’s goal to be zero waste by 2030, this study investigates what factor among five (hygiene, transparency, cost, social influence, and convenience) is the most important in increasing students’ willingness to participate in a campus-wide container sharing program. One hundred and sixty-nine participants completed a Qualtrics survey distributed through convenience sampling and consisted of a 5-point Likert scale, multiple-choice and open-ended questions. We hypothesized social influence would be the most important factor, but our results led us to retain our hypothesis. The self-report data revealed that hygiene is the most important factor, followed by transparency, convenience, cost, and social influence. These results suggest that UBC should ensure the proper cleaning of containers in their proposed container sharing program. Our findings may have been impacted by a change in behaviour and attitudes due to the COVID-19 pandemic. Future research should explore the evolving role hygiene might have in other zero-waste initiatives that entail the sharing of products.

Renormalization of the energy-momentum tensor in noncommutative complex scalar field theory

description: We study the renormalization of dimension four composite operators and the energy-momentum tensor in noncommutative complex scalar field theory. The proper operator basis is defined and it is proved that the bare composite operators are expressed via renormalized ones with the help of an appropriate mixing matrix which is calculated in the one-loop approximation. The number and form of the operators in the basis and the structure of the mixing matrix essentially differ from those in the corresponding commutative theory and in noncommutative real scalar field theory. We show that the energy-momentum tensor in the noncommutative complex scalar field theory is defined up to six arbitrary constants. The canonically defined energy-momentum tensor is not finite and must be replaced by the "improved" one, in order to provide finiteness. Suitable "improving" terms are found. Renormalization of dimension four composite operators at zero momentum transfer is also studied. It is shown that the mixing matrices are different for the cases of arbitrary and zero momentum transfer. The energy-momentum vector, unlike the energy-momentum tensor, is defined unambigously and does not require "improving", in order to be conserved and finite, at least in the one-loop approximation.

Hubble Space Telescope Observations of the Nova-Like Cataclysmic Variable V348 Puppis

description: We present time series UV and optical (1150 -- 8000 A) spectrophotometry of the novalike (NL) cataclysmic variable V348 Pup through and after eclipse. Outside of eclipse, the spectrum is characterized by a blue continuum, strong line emission, and a broad dip from 2000 -- 3000 A. The continuum eclipse depth is roughly the same over the entire wavelength range covered and there are no signatures of the WD eclipse in the light curves. Model steady-state accretion disk spectra provide a poor fit to the shape of the UV-optical spectrum outside of eclipse. All of these properties are consistent with a disk that is self-shielding, hiding the inner disk and the white dwarf. In eclipse, the emission lines and the broad dip are occulted less than the continuum, indicating vertical extension in these components. The dip is consistent with the presence of a vertical ``Fe II'' absorbing curtain in the system. Archival UV-optical spectra of the lower-inclination NL UX UMa show a bluer continuum and weaker line emission than in V348 Pup and no broad dip. There is strong flickering in V348 Pup. The flickering spectrum shows that the flickering occurs only in the continuum. We did not detect any periodicities associated with the rapid variability. The properties of V348 Pup are consistent with its previous identification as a member of the SW Sex sub-class of NLs.

description: Hysteresis has been observed in de Haas-van Alphen measurements of the Condon domains in silver, and it shows the first-order nature of the transition to the domain state. The hysteresis, and thus the first-order nature, is manifested in a nonlinear effect where a double-valued response of the amplitude with the applied external field is observed.

description: Let $S=K[x_1,\ldots,x_n]$ be the polynomial ring over a field $K$, and let $A$ be a finitely generated standard graded $S$-algebra. We show that if the defining ideal of $A$ has a quadratic initial ideal, then all the graded components of $A$ are componentwise linear. Applying this result to the Rees ring $\mathcal{R}(I)$ of a graded ideal $I$ gives a criterion on $I$ to have componentwise linear powers. Moreover, for any given graph $G$, a construction on $G$ is presented which produces graphs whose cover ideals $I_G$ have componentwise linear powers. This in particular implies that for any Cohen-Macaulay Cameron-Walker graph $G$ all powers of $I_G$ have linear resolutions. Moreover, forming a cone on special graphs like unmixed chordal graphs, path graphs and Cohen-Macaulay bipartite graphs produces cover ideals with componentwise linear powers.

title: Ethylene oxide-propylene oxide copolymers in yeast fermentations
Creators: name: Newsome, Graham
Publisher: name: The Open University
Year: 1989

description: Ethylene oxide - propylene oxide copolymers are prepared by addition of ethylene oxide to polypropylene glycol. One of the uses of these compounds is to inhibit foam formation in aqueous media. The main purpose of this work has been to try to determine how variation of molecular weight and ethylene oxide content of these polymers changes their efficiency of foam inhibition in a particular foaming system, namely an aerobic yeast fermentation. In addition attempts have been made to study the effect of the polymers upon yeast growth and again to relate this to variations in molecular weight and ethylene oxide content. The results obtained show that polymers with ethylene oxide contents below 15% by weight were most effective with respect to inhibition of foaming. Increasing the molecular weight of these polymers resulted in more effective control of foaming. The results also show that all of the polymers studied caused a reduction in yeast growth although this effect was less marked with a polymer having a molecular weight of 2271 and an ethylene oxide content of 11% by weight. Methods have also been developed for purification of the commercially available polymers and characterisation of them using gel permeation chromatography and carbon-13 NMR.
