description: 3. Aphis nerii Boyer de Fonscolombe, Soc. Ent. France, Ann. 10: 167, 1841. The milkweed aphis was found once at Piti. A colony occurred on the common milkweed (Asclepias curassavica) at the Agricultural School Firm. Another colony was found on the same plant at Fadian. A large green aphid was found on the large marsh reed (Trichoon ro:rburghii) on two occasions, once at Inarajan and again at Piti, but I failed to preserve any for identification. Aphis sacchari was not observed at any time on sugar cane. Fullaway reported in 1911 an aphid on banana resembling Pentalonia nigronervosa, a species known on banana in Hawaii.

description: In a September 1976 PRL Eguchi and Freund considered two topological invariants: the Pontryagin number $P \sim \int d^4x \sqrt{g}R^* R$ and the Euler number $χ\sim \int d^4x \sqrt{g}R^* R^*$ and posed the question: to what anomalies do they contribute? They found that $P$ appears in the integrated divergence of the axial fermion number current, thus providing a novel topological interpretation of the anomaly found by Kimura in 1969 and Delbourgo and Salam in 1972. However, they found no analogous role for $χ$. This provoked my interest and, drawing on my April 1976 paper with Deser and Isham on gravitational Weyl anomalies, I was able to show that for Conformal Field Theories the trace of the stress tensor depends on just two constants: \[ g^{μν}\langle T_{μν}\rangle=\frac{1}{(4π)^2}(cF-aG)\] where $F$ is the square of the Weyl tensor and $\int d^4x\sqrt{g} G/(4π)^2$ is the Euler number. For free CFTs with $N_s$massless fields of spin $s$ \[ 720c=6N_0 + 18N_{1/2} + 72 N_1~~~~ 720a=2N_0 + 11N_{1/2} + 124N_1 \]

description: We present results from a search for high-redshift J--band ``dropout'' galaxies in the portion of the GOODS southern field that is covered by extremely deep imaging from the Hubble Ultradeep Field (HUDF).Using observations at optical, near-infrared and mid-infrared wavelengths from the Hubble and Spitzer Space Telescopes and the ESO-VLT, we search for very massive galaxies at high redshifts and find one particularly remarkable candidate. Its spectral energy distribution is consistent with a galaxy at z ~ 6.5 and a stellar mass of 6x10e11 M(sun) (for a Salpeter IMF). We interpret a prominent photometric break between the near-infrared and Spitzer bandpasses as the 3646A Balmer discontinuity. The best-fitting models have low reddening and ages of several hundred Myr, placing the formation of the bulk of the stars at z > 9. Alternative models of dusty galaxies at z ~ 2.5 are possible but provide significantly poorer fits. The object is detected with Spitzer at 24 micron. This emission originats from an obscured active nucleus or star formation. We present optical and near-infrared spectroscopy which has, thus far, failed to detect any spectral features. This helps limit the solution in which the galaxy is a starburst or active galaxy at z ~ 2.5. If the high-redshift interpretation is correct, this object would be an example of a galaxy that formed by a process strongly resembling traditional models of monolithic collapse, in a way which a very large mass of stars formed within a remarkably short period of time, at very high redshift.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The problem of calculating collective density fluctuations in quantum liquids is revisited. A fully quantum mechanical self-consistent treatment based on a quantum mode-coupling theory [E. Rabani and D.R. Reichman, J. Chem. Phys.116, 6271 (2002)] is presented. The theory is compared with the maximum entropy analytic continuation approach and with available experimental results. The quantum mode-coupling theory provides semi-quantitative results for both short and long time dynamics. The proper description of long time phenomena is important in future study of problems related to the physics of glassy quantum systems, and to the study of collective fluctuations in Bose fluids.

This sugar cane aleurodid was found sparsely in small colonies on cane in a small field on the Sumay Road about two miles south of Piti, October 3, 17, 1936. At Mata, November 11, some larger colonies were found on a single stool of cane in a garden. They were attended by the "fire ant" (Solenopsis geminata rufa). On Mt. Alifan, May 26, a colony was found on· the grass Paspalum conjugatum. This aleurodid is known to infest sugar cane from Mauritius, Ceylon, Java, Philippines, Formosa, to Fiji and Samoa. This is the first record of it in Guam. Immature aleurodids were found on taro leaves in a gulch near Mt. Tenjo, May3. Noadultswereobtainedandnomaterialpreserved.

The paper has a pedagogical and introductory purposes and is intended to help the reader in better understanding the existing literature on the subject. The functional calculations are based on the solution by Avramidi and Barvinsky \& Vilkovisky for the heat kernel and are performed in curved spacetime. One of the important points is that the main structure of non-localities is the same as in the flat background.

description: As female primates carry and nurse the fetus, it naturally falls on them to rear the o¤spring. On the assumption that males are at least equally adept at obtaining food, it follows that they generate a surplus which they might either share with females or consume themselves. This choice lies at the heart of an evolutionary battle of the sexes. If females suceed in obtaining a large share of the surplus, there is little scope for size dimorphism between males and females; otherwise males can use the surplus to sustain larger and stronger bodies, which are advantageous in sexual competition with other males. Besides competing with males, females may compete with each other. Moreover, dependency may coincide with sexiness and such dependency can persist. This paper examines these ideas in a game-theoretic setting
An investigation to the implementation of rainwater harvesting and filtration system in the new Student Union Building (SUB) at UBC

description: The University of British Columbia is under its way in designing and constructing the New Student Union Building (SUB). To be completed in 2014, the New SUB will be a unique facility that serves as a dynamic gathering place for students to interact and grow a vibrant student community on the UBC-Vancouver campus. Aiming for Leadership in Energy and Environmental Design (LEED) Platinum Certification, which is the highest green building rating in North America, the design and construction of the New SUB will serve as a model for future sustainable development around the world. LEED promotes five key areas of sustainable approach, including sustainable site development, materials selection, indoor environmental quality, energy efficiency and water efficiency. In order to achieve the LEED platinum standards, the New SUB will significantly lower its water consumption by collecting, filtering and storing rainwater in cisterns for various uses, including irrigating rooftop garden and flushing toilets. This project starts by outlining the components of rainwater harvesting (RWH) system, which consists of ten parts: gutter guards, leaf screens, first-flush diverters, roof washers, sand filters, settling tanks, in-line filter, storage system, distribution system and purification system. Followed by that is the detailed introduction of five types of filtration methods, including UV light, chlorination, ozonation, reverse osmosis and thermal treatment. The report then goes further to analyze two currently implemented RWH projects in North America in terms of water collection and usage. And finally the project concludes with triple-bottom line analysis and recommendation to the feasibility of implementing RWH system on the New SUB. 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: We provide a new framework for the analysis of network formation and demonstrate the existence of farsightedly consistent directed networks. Our framework extends the standard notion of a network and also introduces the notion of a supernetwork. A supernetwork is made up of a collection of directed networks (the nodes) and represents (via the arcs connecting the nodes) preferences and rules governing network formation. By extending Chwe’s 1994 result on the nonemptiness of farsightedly consistent sets, we show that for any supernetwork there exists a nonempty subset of farsightedly consistent directed networks.

Lakkella

description: Lakkella n. gen.
 TYPE SPECIES. — Lakkella jamalica n. sp.
 ETYMOLOGY. — The genus name derives from Greek “λακκος”, pit, hole, and suffix “- ella ”. The name refers to the presence of pit-like heterozooecia (“leptozooecia”).
OCCURRENCE. — Lakaftari: central Iran, Jamal Formation, Middle Permian.
DIAGNOSIS. — Branched colony with 4-6 rows of short tubular autozooecia opening on the one side. Autozooecia elongated oval to slightly rectangular in deep tangential section with well developed vestibule. Autozooecial apertures oval to lens-shaped. Thin ridges between apertures. Single leptozooecium and small acanthostyle in the wall between apertures longitudinally; rare smaller styles between apertures. Inner granular skeleton hyaline, well developed; outer lamellar skeleton relatively thick.
COMPARISON
 The new genus is superficially similar to Streblocladia Crockford, 1944. However, it differs in having acanthostyles and only one heterozooecium between apertures. Streblocladia is known from Upper Carboniferous to Lower Permian (Sakmarian) of Western Australia. Crockford (1944b) did not illustrate the interior morphology, so that a closer comparison is impossible. Lakkella n. gen. is also similar to Rhombocladia Rogers, 1900, Chainodictyon Foerste, 1887 and Kallodictyon Morozova, 1981, especially in apertural shape, arrangement of autozooecia, and presence of acanthostyles. However, it differs in colony form and autozooecial shape.

description: In a classic model of tax competition, we show that the level of public good provision and taxation in a Nash equilibrium can be efficient or inefficient with either too much, or too little public good provision. The key is whether there exists a unilateral incentive to deviate from the efficient state and, if so, whether this entails raising or lowering taxes. A priori, there is no reason to suppose the incentive is in either one direction or the other. In addition, we demonstrate conditions ensuring existence of an asymmetric Nash equilibrium with efficient public good provision. As in prior literature, local amenities enhance capital’s productivity. Prior literature, however, focuses on under-provision of public goods.

MATÉRIEL. — Sud du relais TV, niveau 30, PFT132.1-4, 4 exemplaires.
DESCRIPTION
La coquille, en très bon état de conservation (Fig. 4B), montre une morphologie identique à celle de l’holotype de la montagne de Suavicino, dans l’Apennin central (Canavari 1880b: pl. 3, fig. 7). Taille moyenne (L = 13,3 mm), contour subpentagonal arrondi plus large que long (l/L = 1,19), avec une plus grande largeur située sur le tiers antérieur de la longueur. Plus grande épaisseur des deux valves en leur milieu, le renflement de l’umbo dorsal étant également marqué. Épaisseur E/L = 0,70. Espèce sans aucune costulation. Uniplication frontale élevée (h = 7 mm), large et arrondie, prenant naissance vers le quart antérieur de la longueur. Le pli, peu distinct, se raccorde progressivement aux parties latérales de la valve dorsale. Il lui correspond un sinus ventral large, mais peu profond. Les commissures latérales, légèrement obliques en direction ventrale sur leur trajet postérieur, se recourbent fortement à l’approche du front.
Petit crochet pointu, légèrement recourbé et quasiment en contact avec l’umbo dorsal. Minuscule foramen punctiforme, mésothyride entre des crêtes latérales du crochet longues et bien exprimées. Deltidium non apparent.
 Le rapprochement signalé par Canavari (1880a, b) d’ Apringia aptyga avec l’espèce costée « Rhynchonella » mariottii (Zittel 1869: pl. 14, fig. 17) n’est pas justifié à notre avis. La même remarque concerne l’attribution suggérée par Vörös (1983, 1993, 1994) de « R. » mariottii au genre Apringia. Enfin, « Rhynchonella » pisoides (Zittel 1869: pl. 14, figs 15, 16), également de l’Apennin central, et espèce type du genre Pisirhynchia Buckman, 1918, montre aussi une morphologie différente de celle d’ Apringia aptyga.

description: We have identified 12 Seyfert 1 galaxies that exhibit optical polarization spectra similar to those of Seyfert 2 galaxies in which polarized broad-lines are detected. We present new spectropolarimetric observations of 3 of them: Was 45, Mrk 231 and NGC 3227. These objects appear to be polarized as a result of far-field scattering in the polar illumination cones of the circum-nuclear torus. We estimate that they represent between 10 and 30 per cent of the Seyfert 1 population; they are found amongst all the main spectroscopic sub-types, including narrow-line Seyfert 1 galaxies. We have shown elsewhere that Seyfert 1 nuclei more commonly have polarization characteristics that can be attributed to scattering by a compact 'equatorial' scattering region located inside the torus. We propose that both equatorial and polar scattering regions are present in all Seyfert galaxies and argue that the observed range of polarization properties can be broadly understood as an orientation effect. In this scheme, polar-scattered Seyfert 1 galaxies represent the transition between unobscured (the majority of type 1) and obscured (type 2) Seyferts. They are viewed through the upper layers of the torus and are thus subject to moderate extinction (Av ~1-4 mag) sufficient to suppress polarized light from the equatorial scattering region, but not the broad wings of the Balmer lines. The orientation of the polarization position angle relative to the radio source is broadly consistent with the two-component scattering model. More generally, we find that amongst Seyferts 1 galaxies, parallel, perpendicular and intermediate orientations of the polarization PA relative to the radio axis occur roughly in the proportions 2:1:1.

description: Since Hart's [5] and Werner's [10] seminal papers, several conditions have been proposed to show the existence of equilibrium in an asset exchange economy with short-selling. In this note, we discuss the relationship between two no-arbitrage conditions. The ¯rst condition is the assumption that the individually rational utility set U is compact, as considered by Dana, Le Van and Magnien [1]. The second is inconsequential arbitrage, introduced by Page, Wooders and Monteiro [9]. The main result of this comparison is to show that the inconsequential arbitrage condition is stronger than the assumption that U is compact.

Except for phantom we admit various forms of standard types of matter and discuss the problem of singularities for these cosmologies. The singularities are different from those of standard matter cosmology since they appear for infinite values of the scale factor. We also find an interesting relation between the phantom models and standard matter models which is like the duality symmetry of string cosmology.

description: The purpose of the article is to develop practical recommendations for the formation of taxonomy of agricultural enterprises’ sustainable development reporting based on eco-social information. Items of the Balance Sheet and the Financial Results Report were analyzed in the article. Analytical data taxonomy recommendations within environmental and social accounting were given in the article. The items of the financial statements have been agreed with the Chart of Accounts for the bookkeeping of assets and liabilities. The methodology of displaying natural capital on balance and off-balance accounts is suggested. The reporting forms that allow to trace the dynamics of achieving agricultural enterprise’s sustainable development, as well as to control the costs of environmental and social activities were proposed. Practical recommendations for agroindustrial small and microenterprises for forming financial statements in the «Balance Sheet of Sustainable Development» and «Report on the financial results of sustainable development» are given. The Balance Sheet of Sustainable Development of an agricultural enterprise is a constitutive document of financial statements and management reports, an information base on socio-ecological and economic relations and the results of agricultural activities, for analyzing, rationing, planning, organizing production, management and control by internal and external users-stakeholders in the innovative direction of the sustainable development vector. The Financial Results Report of the agricultural enterprise’s sustainable development is a source of information not only about the results of operational, financial, investment activities, but also environmental and social.
Search for a Shock Wave around the Crab Nebula

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We have searched the region surrounding the Crab Nebula for the existence of a shock wave with the imaging instruments of the Einstein Observatory. The search is complicated by the scattering of nebula and pulsar X-rays from the imperfectly polished surfaces of the telescope mirror, as well as from interstellar grains along the line of sight. Both of these effects lead to the appearance of X-ray emission, in the form of an X-ray halo, beyond the boundaries of the nebula filaments. We show that the size, shape, and intensity of the halo around the Crab Nebula, above the contribution of mirror scattering, is consistent with what is expected from the scattering from interstellar grains. The upper limit on the X-ray emission from a shock wave is about 1% of the total 0.5-4 keV luminosity of the Crab or about 2E35 erg/s (assuming a distance of 2.2 kpc). This figure applies to a shell whose angular radius is 9 arcminutes. The upper limit is smaller (larger) for a shell of larger (smaller) size. This upper limit is an order of magnitude or more below the flux of Cas A, Tycho, and Kepler SNRs, which are 2 to 3 times younger, but it is still above that of SN 1006.

description: Let G be a linear algebraic group defined over a field k. We prove that, under mild assumptions on k and G, there exists a finite k-subgroup S of G such that the natural map H^1(K, S) -> H^1(K, G) is surjective for every field extension K/k. We give several applications of this result in the case where k an algebraically closed field of characteristic zero and K/k is finitely generated. In particular, we prove that for every z in H^1(K, G) there exists an abelian field extension L/K such that z_L \in H^1(L, G) is represented by a G-torsor over a projective variety. From this we deduce that z_L has trivial point obstruction. We also show that a (strong) variant of the algebraic form of Hilbert's 13th problem implies that the maximal abelian extension of K has cohomological dimension =< 1. The last assertion, if true, would prove conjectures of Bogomolov and Koenigsmann, answer a question of Tits and establish an important case of Serre's Conjecture II for the group E_8.

Traditionally, these states originate from total destructive interference of radiation from two or more non-orthogonal modes in periodic structures. In this work, we demonstrate a novel class of embedded eigenstates based on Berreman modes in epsilon-near-zero (ENZ) layered materials and propose realistic silicon carbide (SiC) structures supporting high-Q (~10^3) resonances based on these principles. The proposed structures demonstrate strong absorption in a narrow spectral and angular range, giving rise to quasi-coherent and highly directive thermal emission.

description: Low frequency ($ν\lesssim 150\,$MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission from the Sun has been used to study coronal structure, mass ejections, space-weather conditions around the planets (Schwenn 2006). Searches for low-frequency emission from other stars have only detected a single active flare-star (Lynch et al. 2017) that is not representative of the wider stellar population. Here we report the detection of low-frequency radio emission from a quiescent star, GJ 1151--- a member of the most common stellar type (red dwarf or spectral class M) in the Galaxy. The characteristics of the emission are similar to those of planetary auroral emissions (Zarka 1998) (e.g. Jupiter's decametric emission), suggesting a coronal structure dominated by a global magnetosphere with low plasma density. Our results show that large-scale currents that power radio aurorae operate over a vast range of mass and atmospheric composition, ranging from terrestrial planets to main-sequence stars. The Poynting flux required to produce the observed radio emission cannot be generated by GJ 1151's slow rotation, but can originate in a sub-Alfvénic interaction of its magnetospheric plasma with a short-period exoplanet. The emission properties are consistent with theoretical expectations (Zarka 2007; Lanza 2009; Saur et al. 2013; Turnpenney et al. 2018) for interaction with an Earth-size planet in a $\sim 1-5$ day-long orbit.

description: We present a relativistic three-body equation to study the stability of the isolated three-body system and the correlations in a medium of finite temperatures and densities. Relativity is implemented utilizing the light front form. Using a zero-range force we find the relativistic analog of the Thomas collapse and investigate the possibility that the nucleon exists as a Borromean system. Within a systematic Dyson equation approach we calculate the three-body Mott transition and the critical temperature of the color-superconducting phase.

description: The new Student Union Building being constructed at the University of British Columbia will have several new kitchens in order to cook for the growing population of students. A current decision of designers is whether to install traditional gas stove tops, or the newer, potentially more sustainable induction stove technology. This report compares the installation of these two different stove types according to the environmental, economic, and social pros and cons. Using data from the United States Department of Energy, several sources on both gas and induction stove tops, as well as local costs for natural gas and electricity, it was able to be determined that while induction stove tops are the more sustainable, healthy choice of stove top, they will cost more per annum to maintain in the new SUB and are potentially more difficult for cooks to use. Therefore, it is recommended that the designers of the new SUB proceed with installing both gas stoves and induction stoves in order to maintain a balance between the pros and cons.

description: We analyze faces generated by points in an arbitrary convex set and their relative algebraic interiors, which are nonempty as we shall prove. We show that by intersecting a convex set with a sublevel or level set of a generalized affine functional, the dimension of the face generated by a point may decrease by at most one. We apply the results to the set of quantum states on a separable Hilbert space. Among others, we show that every state having finite expected values of any two (not necessarily bounded) positive operators admits a decomposition into pure states with the same expected values. We discuss applications in quantum information theory.

description: We analyze the fluctuations of the dressed sliver solution found in a previous paper, hep-th/0311198, in the operator formulation of Vacuum String Field Theory. We derive the tachyon wave function and then analyze the higher level fluctuations. We show that the dressing is responsible for implementing the transversality condition on the massless vector. In order to consistently deal with the singular $k=0$ mode we introduce a string midpoint regulator and we show that it is possible to accommodate all the open string states among the solutions to the linearized equations of motion. We finally show how the dressing can give rise to the correct ratio between the energy density of the dressed sliver and the brane tension computed via the three-tachyons-coupling.

description: We present a detailed spectroscopic analysis of the recently discovered fast evolving Type I superluminous supernova (SLSN-I), SN 2019neq (at redshift z = 0.1059) comparing it to the well-studied slow evolving SLSN-I, SN 2010kd (z = 0.101). Our investigation concentrates on optical spectra taken during the photospheric phase. The observations of SN 2019neq were carried out with the 10m Hobby-Eberly Telescope (HET) Low Resolution Spectrograph-2 (LRS2) at McDonald Observatory. We apply the SYN++ code to model the spectra taken at -4 days, +5 days and +29 days from maximum light. We examine the chemical evolution and ejecta composition of the SLSN by identifying the elements and ionization states in its spectra. Our analysis confirms that SN 2019neq is a fast evolving SLSN-I. We derive the number density of each ionization state at the epoch of the three observations. Finally, we give constraints on the lower limit of the ejecta mass and find a hint for a possible relation between the evolution timescale and the ejected mass of SLSNe-I.

description: Using Trades and Quotes data from the Paris stock market, we show that the random walk nature of traded prices results from a very delicate interplay between two opposite tendencies: long-range correlated market orders that lead to super-diffusion (or persistence), and mean reverting limit orders that lead to sub-diffusion (or anti-persistence). We define and study a model where the price, at any instant, is the result of the impact of all past trades, mediated by a non constant `propagator' in time that describes the response of the market to a single trade. Within this model, the market is shown to be, in a precise sense, at a critical point, where the price is purely diffusive and the average response function almost constant. We find empirically, and discuss theoretically, a fluctuation-response relation. We also discuss the fraction of truly informed market orders, that correctly anticipate short term moves, and find that it is quite small.

description: This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results and applications, complemented with a few new derivations and discussions. We pay special attention to the role of the equations of motion and to the relation between classical and quantum theories. Pointwise energy conditions were first introduced as physically reasonable restrictions on matter in the context of general relativity. They aim to express e.g. the positivity of mass or the attractiveness of gravity. Perhaps more importantly, they have been used as assumptions in mathematical relativity to prove singularity theorems and the non-existence of wormholes and similar exotic phenomena. However, the delicate balance between conceptual simplicity, general validity and strong results has faced serious challenges, because all pointwise energy conditions are systematically violated by quantum fields and also by some rather simple classical fields. In response to these challenges, weaker statements were introduced, such as quantum energy inequalities and averaged energy conditions. These have a larger range of validity and may still suffice to prove at least some of the earlier results. One of these conditions, the achronal averaged null energy condition, has recently received increased attention. It is expected to be a universal property of the dynamics of all gravitating physical matter, even in the context of semiclassical or quantum gravity.

description: The paper aims to systematize business management strategies and identify their potential opportunities for the development of the competitive business advantages in transition economies. Characteristics of the features of modern business in developing countries (on the example of Ukraine) are given in the article in concise form. The relevance of the study of the relationship between strategy and business management is substantiated. Modern interpretations of the concepts of «strategy», «strategic management», «strategic set of strategies», «business» and «competitive business potential» are presented. A generalized classification of strategies used in practice for effective business management and its development is described. Possibilities of strategies for formation of competitive business advantages in the modern conditions of market transformations are determined. The scheme of the pyramid hierarchy of a «strategic set of strategies» of a diversified organization is presented. An analog model of competitive business potential by implementing a strategic set of strategies is formalized. Directions of further research are recommended. They include: analysis of the impact of strategies on the process of business management, evaluating the effectiveness of using strategies for effective business management and the choice of priority strategies for effective business management.

description: Before studying the pentaquark system we examine the spectral weights of the two lowest scattering states in the two-pion system in the isospin I=2 channel on lattices of size $16^3\times 32$, $24^3 \times 32$ and $32^3 \times 64$ at $β=6.0$ in the quenched theory. We find that the spectral weights scale with the volume for large time separations. Therefore very accurate data are necessary in order that the spectral weights determined on different volumes yield a ratio that is precise enough to distinguish a scattering state from a single particle state. The pentaquark system is studied on the same lattices and scaling of the spectral weights of the low lying state is investigated. The accuracy of the results obtained for the scaling of spectral weights do not allow us to exclude a pentaquark resonance.
