description: Polypora sinokoninckiana Yang & Lu, 1962 (Figs 10P; 11 A-D; Table 27)
 Polypora sinokoninckiana Yang & Lu, 1962: 93, pl. 17, figs 10-12.
MATERIAL EXAMINED. — 1-3-4, 9-5-4, 9-5-8, 9-7.
OCCURRENCE. — Southern China; Maokao Formation, Permian (?Murgabian) (Yang & Lu 1980). Lakaftari: central Iran, Jamal Formation, Middle Permian.
DESCRIPTION
Micrometric formula: 8-11.5/5-7//16-22. Reticulated colonies with straight branches, joined by relatively thin dissepiments. Autozooecia arranged in 3-4 alternating rows on branches. Apertures circular, spaced 5-6 per length of a fenestrule; 1-2 small nodes developed in peristome. Shape of fenestrules varying from narrow oval to rectangular and triangular. Keels absent. Nodes small, rounded, hyaline, arranged in regular rows between apertures on the obverse colony surface, widely spaced. Internal granular skeleton moderately thick, well developed, continuous with nodes, rods, peristome and across dissepiments. Outer lamellar skeleton moderately thick, containing abundant rods 5-6 µm in diameter. Ovicells occurring occasionally, shaped as spherical chambers attached at distal part of apertures, reaching 0.14 mm in diameter.
INTERIOR DESCRIPTION
Autozooecia rhombic to hexagonal in the middle tangential section; relatively short in longitudinal section, with well developed vestibule; aperture positioned at distal to distal-abaxial end of chamber. Hemisepta absent. Terminal diaphragms occurring.
COMPARISON
 Polypora sinokoninckiana is similar to P. timorensis Bassler, 1929 from the Permian of Indonesia. The latter species differs in having longer fenestrules (c. 2 vs. 0.99-1.47 mm in present material), and thinner branches (c. 0.45 vs. 0.60 mm in present material).

description: Há um potencial grande para produzir arroz sob irrigação controlada na várzea amazônica. Se só 5% da várzea na Amazônica brasileira fossem explorados e produzissem 10 toneladas por hectare, a produção de arroz no Brasil se elevaria ao triplo. O desenvolvimento desse potencial acarretaria todos os difíceis critérios sociais de exploração para quem e por quem. E, muito antes que mesmo uma pequena fração desse potencial seja desenvolvida, haverá sérios custos ambientais que 96 serão diminuídos através de cuidadoso planejamento e administração ambientais. Aos preços correntes do arroz, e especialmente se forem proporcionados incentivos para a sua exploração, a produção do arroz irrigado controlado afigura-se bastante lucrativa para a exploração comercial que utilize capital e tecnologia de energia intensiva. Dentro da abordagem de mão-de-obra intensiva, parece que a renda familiar derivada da produção de arroz irrigado controlado seria duas a quatro vezes maior, arroz em terra firme. O que é igualmente importante é que as colônias baseadas no arroz irrigado teriam uma densidade de povoamento adequada para a organização comunitária e a provisão e utilização de serviços sociais, ao contrário da situação em terra firme. Estas conclusões deverão ser interpretadas com cautela, desde que a análise é, necessariamente, de natureza preliminar. Para cada uma das três abordagens para a produção de arroz na Amazônia, é apresentada uma larga faixa de estimativas de rendimentos, em parte, para ilustrar os efeitos das incertezas ambientais e de mercado e, em parte, porque as tecnologias de produção atuais não estão ainda bem documentadas. Como todos os dados e pressuposições básicas sobre os quais se baseia a análise estão claramente apresentados nos apêndices, outros pesquisadores poderão facilmente corrigir a análise e restringir a faixa dos rendimentos estimados, à medida que se puder dispor de melhores informações.

description: We continuously monitored the blazar S5 0716+714 in the optical $g$, $r$ and $i$ bands from Nov. 10, 2017 to Jun. 06, 2019. The total number of observations is 201 nights including 26973 data points. This is a very large quasi-simultaneous multicolor sample for the blazar. The average time spans and time resolutions are 3.4 hours and 2.9 minutes per night, respectively. During the period of observations, the target source in the $r$ band brightens from $14^{\rm m}.16$ to $12^{\rm m}.29$ together with five prominent sub-flares, and then first becomes fainter to $14^{\rm m}.76$ and again brightens to $12^{\rm m}.94$ with seven prominent sub-flares. For the long-term variations, we find a strong flatter when brighter (FWB) trend at a low flux state and then a weak FWB trend at a higher flux state. A weak FWB trend at a low flux state and then a strong FWB trend at a higher flux state are also reported. Most of sub-flares show the strong FWB trends, except for two flares with a weak FWB trend. The particle acceleration and cooling mechanisms together with the superposition of different FWB-slopes from sub-flares are likely to explain the optical color behaviours. A scenario of bent jet is discussed.

description: Abstract: In this paper, we use Genetic Algorithms to nd the Minimum Dominating Set (MDS) of Unit Disk Graphs (UDG). UDGs are used for modelling Ad-Hoc networks and finding MDS in such graphs is a promising approach to clustering the wireless Ad-Hoc networks. The MDS problem is proved to be NP-complete. The simulation results show that the proposed algorithm outperforms the existing algorithms for nding MDS in terms of the DS size.

Investigation and recommendation of pest population supression in artificial urban waterscape
Creators: name: Yang, Nelson (Maki)
Publisher: name: The University of British Columbia
Year: 2014

description: In late 2003, the residential areas of Southern UBC campus, Hawthorn Place had a small pond about 8” deep installed at the lower end of a rain-fed artificial creek constructed with rocks over plastic membrane. Algae were found to be growing in the pond. The algae growth was assumed to result in insect reproduction and in combination with the residents pest complaints, the storm basin drain was lowered to prevent water accumulation thus removing the pond. This project is being proposed to examine the insect fauna in the Hawthorn Place Park pond once it is rewetted, and to recommend a biological-controlled program to suppress the pest population. The water features will be reintroduced by changing elevation of the drain outlet. Doing so will contribute to headwaters of the watershed that flows from Hawthorn Place through to the Botanical Gardens and then Trail 7 Creek within Pacific Spirit Park. The re-establishment of the headwaters as well as the watershed surface feature is believed to provide ecological services, slowing stormwater, reduce influx into sewage treatment and public amenities by means of a potential children’s park and waterscape feature. Based on the result of the experiment, an ecologically benefiting and sustainable method which will promote local species diversity as well as a chemical free pest management program will be suggested. The experiment will be composed of two phases. Phase one from Jan-April will be the literature stage where the local history of the water feature as well as the various pre-existing biopest protocols will be studied. Phase two from April-August will be the field application stage where a survey of the local pest population will be performed and the result findings of phase one will be put to test followed by a critical evaluation and a recommendation of future pest population suppression based on the tested result.

description: We predict the formation of giant vortices in quasi-two-dimensional quantum dots at high magnetic fields, i.e., in rapidly rotating electron droplets. Our numerical results of quantum dots confined by a flat, anharmonic potential show ground states where vortices are accumulated in the center of the dot, thereby leading to large cores in the electron and current densities. The phenomenon is analogous to what was recently found in rotating Bose-Einstein condensates. The giant-vortex states leave measurable signatures in the ground-state energetics. The conditions for the giant-vortex formation as well as the internal structure of the vortex cores are discussed.

description: The need to secure the Internet is clear to everyone consequently more and more mechanisms to provide security and enhance it at different layers and different applications are being developed. Thus we want to introduce a new and secure method in network security. In this article at first we will survey" chaff and winnowing" method and cryptography method. Then we will discuss about their advantages and disadvantages and we will introduce a new method which it can solve the "chaff and winnowing" method's semantic challenges and make cryptography method safer. This new method uses the advantages of both methods and tries to omit the disadvantages of before methods to make a secure method for general using. Also this method is efficiency in confidentially and authentication problems.

description: Braneworld inflation is a phenomenology related to string theory that describes high-energy modifications to general relativistic inflation. The observable universe is a braneworld embedded in 5-dimensional anti de Sitter spacetime. Whe the 5-dimensional action is Einstein-Hilbert, we have a Randall-Sundrum type braneworld. The amplitude of tensor and scalar perturbations from inflation is strongly increased relative to the standard results, although the ratio of tensor to scalar amplitudes still obeys the standard consistency relation. If a Gauss-Bonnet term is included in the action, as a high-energy correction motivated by string theory, we show that there are important changes to the Randall-Sundrum case. We give an exact analysis of the tensor perturbations. They satisfy the same wave equation and have the same spectrum as in the Randall-Sundrum case, but the Gauss-Bonnet change to the junction conditions leads to a modified amplitude of gravitational waves. The amplitude is no longer monotonically increasing with energy scale, but decreases asymptotically after an initial rise above the standard level. Using an approximation that neglects bulk effects, we show that the amplitude of scalar perturbations has a qualitatively similar behaviour to the tensor amplitude. In addition, the tensor to scalar ratio breaks the standard consistency relation.

description: We investigate the turbulence driving mode of ionizing radiation from massive stars on the surrounding interstellar medium (ISM). We run hydrodynamical simulations of a turbulent cloud impinged by a plane-parallel ionization front. We find that the ionizing radiation forms pillars of neutral gas reminiscent of those seen in observations. We quantify the driving mode of the turbulence in the neutral gas by calculating the driving parameter $b$, which is characterised by the relation $σ_s^2 = \ln({1+b^2\mathcal{M}^2})$ between the variance of the logarithmic density contrast $σ_s^2$ (where $s = \ln({ρ/ρ_0})$ with the gas density $ρ$ and its average $ρ_0$), and the turbulent Mach number $\mathcal{M}$. Previous works have shown that $b\sim1/3$ indicates solenoidal (divergence-free) driving and $b\sim1$ indicates compressive (curl-free) driving, with $b\sim1$ producing up to ten times higher star formation rates than $b\sim1/3$. The time variation of $b$ in our study allows us to infer that ionizing radiation is inherently a compressive turbulence driving source, with a time-averaged $b\sim 0.76 \pm 0.08$. We also investigate the value of $b$ of the pillars, where star formation is expected to occur, and find that the pillars are characterised by a natural mixture of both solenoidal and compressive turbulent modes ($b\sim0.4$) when they form, and later evolve into a more compressive turbulent state with $b\sim0.5$--$0.6$. A virial parameter analysis of the pillar regions supports this conclusion. This indicates that ionizing radiation from massive stars may be able to trigger star formation by producing predominately compressive turbulent gas in the pillars.

description: This paper outlines relationships between exclusive and secure property rights to land, land transfers, farm productivity, access to credit and on-farm investment. A survey of freehold and Trust farmers was conducted in the Madadeni district of KwaZulu to investigate these relationships. Despite the existence of title-deeds, it was found that many of the respondents did not have exclusive use rights to land. Non-exclusive use rights occurred where land was co-owned, mutually occupied by two or more members of a family or registered in the name of a deceased person. Land market activity was generally confined to rental transactions by individuals who had exclusive use of land. In the absence of zoning regulations, several landowners had leased plots to residential tenants, with some farms becoming entirely residential. Results of logit analysis indicate that investment in on-farm improvements is higher where tenure is private and secure. It is concluded that exclusive and secure property rights facilitate the land market, promoting efficiency in agriculture. Recommendations give due consideration to the equity implications of land sale and land rental markets and to the consequences of zoning.

It has been shownhow the kinetic nearest neighbor will be updated at eachtime step in O(k∆k log n) amortized time, where ∆k isthe k-spread of a point set P .Key words: Computational Geometry, Black Box Model, Kinetic, Nearest Neighbor.
Analogues of Alladi's formula

Subjects: subject: Number Theory (math.NT)

description: In this note, we mainly show the analogue of one of Alladi's formulas over $\mathbb{Q}$ with respect to the Dirichlet convolutions involving the Möbius function $μ(n)$, which is related to the natural densities of sets of primes by recent work of Dawsey, Sweeting and Woo, and Kural et al. This would give us several new analogues. In particular, we get that if $(k, \ell)=1$, then $$-\sum_{\begin{smallmatrix}n\geq 2\\ p(n)\equiv \ell (\operatorname{mod} k) \end{smallmatrix}} \frac{μ(n)}{φ(n)} = \frac1{φ(k)},$$ where $p(n)$ is the smallest prime divisor of $n$, and $φ(n)$ is Euler's totient function. This refines one of Hardy's formulas in 1921. At the end, we give some examples for the $φ(n)$ replaced by functions "near $n$", which include the sum-of-divisors function.

description: We consider a system consists of a doped monolayer phosphorene embedded between two hexagonal Boron Nitride (hBN) slabs along the heterostructure direction. The wavevector azimuthal angle dependence of the plasmon-polariton and plasmon-phonon-polariton modes of the hybrid system are calculated based on the random phase approximation at finite temperature. The collective modes illustrate strong anisotropy and strong coupling with phonon modes of the polar media and furthermore, the Landau damping occurs due to the intraband processes when plasmon enters intraband electron-hole continuum. Our numerical results show that the plasmon mode is highly confined to the surface along the zigzag direction. Owing to the strong electron-phonon interaction, the phonon dispersions in the Reststrahlen bands are also angle-dependent. These results are also in agreement with those of the semiclassical model obtained in our calculations.

Coupled Dynamics on Hypergraphs: Master Stability of Steady States and Synchronization

description: In the study of dynamical systems on networks/graphs, a key theme is how the network topology influences stability for steady states or synchronized states. Ideally, one would like to derive conditions for stability or instability that instead of microscopic details of the individual nodes/vertices rather make the influence of the network coupling topology visible. The master stability function is an important such tool to achieve this goal. Here we generalize the master stability approach to hypergraphs. A hypergraph coupling structure is important as it allows us to take into account arbitrary higher-order interactions between nodes. As for instance in the theory of coupled map lattices, we study Laplace type interaction structures in detail. Since the spectral theory of Laplacians on hypergraphs is richer than on graphs, we see the possibility of new dynamical phenomena. More generally, our arguments provide a blueprint for how to generalize dynamical structures and results from graphs to hypergraphs.
Flaring vs. self-shadowed disks: the SEDs of Herbig Ae/Be stars

Publisher: name: arXiv

description: Isolated Herbig Ae stars can be divided into two groups (Meeus et al. 2001): those with an almost flat spectral energy distribution in the mid-infrared (`group I'), and those with a strong decline towards the far-infrared (`group II'). In this paper we show that the group I vs. II distinction can be understood as arising from flaring vs. self-shadowed disks. We show that these two types of disks are natural solutions of the 2-D radiation-hydrostatic structure equations. Disks with high optical depth turn out to be flaring and have a strong far-IR emission, while disks with an optical depth below a certain threshold drop into the shadow of their own puffed-up inner rim and are weak in the far-IR. In spite of not having a directly irradiated surface layer, self-shadowed disks still display dust features in emission, in agreement with observations of group II sources. We propose an evolutionary scenario in which a disk starts out with a flaring shape (group I source), and then goes through the process of grain growth, causing the optical depth of the disk to drop and the disk to become self-shadowed (group II source). We show that this scenario predicts that the (sub-)millimeter slope of the disk changes from steep (small grains) to Rayleigh-Jeans-like (large grains) in the early stages of evolution, so that all group II sources are expected to have Rayleigh-Jeans-like slopes, while some group I sources may still have steep (sub-)millimeter slopes.

description: This article analyses the marketing possibilities of dry beans in South Africa on the basis of certain theoretical principles and available market information. This is done through the consideration of the demand and supply of dry beans, after which concentration in the South African dry bean market is analysed. Characteristics of an ideal marketing system are discussed followed by a discussion of the marketing possibilities of dry beans given the realities of demand and supply and market concentration. The market realities of demand and supply show that the dry bean market does not have the characteristics suitable for control and that a single channel marketing system will therefore not be appropriate. Only measures which would assist the market in achieving higher efficiency should be considered.

description: O presente artigo examina o papel do agricultor na produção e distribuição de novas informações, especialmente as de natureza tecnológica, a partir de um modelo alternativo de comunicação fundamentado nos modelos clássicos de comunicação. Inicialmente, faz-se uma ligeira revisão de pesquisas em comunicação, realizadas de forma seqüencial e acumulativa, e suas implicações teóricas, práticas e metodologia, questionando-se algumas sugestões geralmente presentes nestas investigações e elaborações teóricas. A partir de uma amostra aleatória simples para uma população rural típica do Estado do Rio Grande do Sul, utilizando-se um instrumento de coleta de dados, estruturado quanto à forma mas não quanto ao conteúdo, verificou-se que agricultores estão aptos a participar do processo de produção e distribuição de novos conhecimentos, a partir da manifestação de seus problemas sentidos e vividos, constituíveis em dados úteis para pesquisadores, tomadores de decisões de políticas agrícolas etc., quando coletados de forma sistemática e periódica.

description: The magnetic penetration depth $λ(0)$ in polycrystalline MgB$_{2}$ for different boron isotopes ($^{10}$B/$^{11}$B) was investigated by transverse field muon spin rotation. No boron isotope effect on the penetration depth $λ(0)$ was found within experimental error: $Δλ(0)/λ(0) = -0.8(8)%$, suggesting that MgB$_{2}$ is an adiabatic superconductor. This is in contrast to the substantial oxygen isotope effect on $λ(0)$ observed in cuprate high-temperature superconductors.

description: Neste trabalho deduz-se qual é o número máximo de variáveis climáticas que podem ser introduzidos em uma função de produção ajustada aos dados obtidos de um experimento de adubação repetido durante n anos no mesmo local. Se não houver nenhuma modificação na maneira de conduzir o experimento durante os n anos, esse número máximo de variáveis climáticas é n-1. Se houver alterações, de um ano para outro, na variedade utilizada, sendo m (com m < n) o número de diferentes variedades utilizadas durante os n anos, mas de maneira que em cada ano seja cultivada apenas uma das variedades, então o número máximo de variedades climáticas que podem ser introduzidos na função de produção é n - m.
Generic bivariate multi-point evaluation, interpolation and modular composition with precomputation

description: Suppose $\mathbb{K}$ is a large enough field and $\mathcal{P} \subset \mathbb{K}^2$ is a fixed, generic set of points which is available for precomputation. We introduce a technique called \emph{reshaping} which allows us to design quasi-linear algorithms for both: computing the evaluations of an input polynomial $f \in \mathbb{K}[x,y]$ at all points of $\mathcal{P}$; and computing an interpolant $f \in \mathbb{K}[x,y]$ which takes prescribed values on $\mathcal{P}$ and satisfies an input $y$-degree bound. Our genericity assumption is explicit and we prove that it holds for most point sets over a large enough field. If $\mathcal{P}$ violates the assumption, our algorithms still work and the performance degrades smoothly according to a distance from being generic. To show that the reshaping technique may have an impact on other related problems, we apply it to modular composition: suppose generic polynomials $M \in \mathbb{K}[x]$ and $A \in \mathbb{K}[x]$ are available for precomputation, then given an input $f \in \mathbb{K}[x,y]$ we show how to compute $f(x, A(x)) \operatorname{rem} M(x)$ in quasi-linear time.

Longitudinal drift of Tayler instability eigenmodes as a possible explanation for super-slowly rotating Ap stars

description: Rotation periods inferred from the magnetic variability of some Ap stars are incredibly long, exceeding ten years in some cases. An explanation for such slow rotation is lacking. This paper attempts to provide an explanation of the super-slow rotation of the magnetic and thermal patterns of Ap stars in terms of the longitudinal drift of the unstable disturbances of the kink-type (Tayler) instability of their internal magnetic field. The rates of drift and growth were computed for eigenmodes of Tayler instability using stellar parameters estimated from a structure model of an A star. The computations refer to the toroidal background magnetic field of varied strength. The non-axisymmetric unstable disturbances drift in a counter-rotational direction in the co-rotating reference frame. The drift rate increases with the strength of the background field. For a field strength exceeding the (equipartition) value of equal Alfven and rotational velocities, the drift rate approaches the proper rotation rate of a star. The eigenmodes in an inertial frame show very slow rotation in this case. Patterns of magnetic and thermal disturbances of the slowly rotating eigenmodes are also computed. The counter-rotational drift of Tayler instability eigenmodes is a possible explanation for the observed phenomenon of super-slowly rotating Ap stars.

DESCRIPTION
Encrusting colonies, often hollow, tubular (encrusting ephemeral cylindrical substrates). Encrusting sheets 0.6-2.2 mm thick, tubular colonies having rounded lumen 3-6 mm in diameter. Autozooecia budding from substrate at low angles. Autozooecial apertures rounded, having well developed, horseshoeshaped lunaria, spaced 3.5-4.5 in 2 mm. Autozooecial diaphragms rare to absent in short autozooecia (often developed at their bases), abundant in longer autozooecia, complete, thin, deflected orally. Vesicles polygonal in tangential section, arranged in 1-3 rows between autozooecia, having flat or slightly concave roofs, spaced 8-15 per 1 mm of the colony thickness. Maculae consisting of vesicular skeleton, rounded, 0.66-1.20 mm in diameter, spaced regularly on the colony surface.
COMPARISON
 Sakagami (1980) described a new species Fistulipora pseudomonticulosa because of rare diaphragms in autozooecia. However, an investigation of a large amount of thin sections of the present material revealed a variation in the number of autozooecial diaphragms. Fistulipora monticulosa is similar to F. timorensis, which is widely distributed in Permian rocks of Asia (Indonesia, Thailand, Primorye, Iran). The most striking difference is the growth form: unilaminar encrusting, commonly tubular in F. monticulosa, multilamellar encrustings rare; usually uni- and multilamellar encrusting colonies in F. timorensis, tubular colonies unknown. Furthermore, apertures in F. timorensis are larger (0.35 vs. 0.29 mm in F. monticulosa).

description: Este estudo preocupou-se com a escolha de um método operacional objetivando reduzir o viés introduzido na estimação de índices estacionais de quantidades, devido ao tamanho desigual dos meses durante o ano e a anos bissextos, trazendo maior precisão às estimativas. Resultados similares foram obtidos com o emprego de métodos que corrigem as séries originais de dados de quantidades e métodos que corrigem índices já calculados a partir de séries originais não disponíveis para correção, o que não permite a realização de nova análise de variância. Quando aplicadas a diversos tipos de pescado, as correções resultaram em redução nos valores de F e em aumento nos índices estacionais para fevereiro.

description: The dynamics of strongly interacting trapped dilute Fermi gases (dilute in the sense that the range of interatomic potential is small compared with inter-particle spacing) is investigated in a single-equation approach to the time-dependent density-functional theory. Our results are in good agreement with recent experimental data in the BCS-BEC crossover regime. It is also shown that the calculated corrections to the hydrodynamic approximation may be important even for systems with a rather large number of atoms.

description: Commodity arbitrage condition equates expected commodity prices to nominal interest rates plus storage costs. Any risk premium is normally subsumed in storage costs. Such an arbitrage restricts commodity marketing to speculative activities. This is an oversimplification of all the activities undertaken in commodity marketing. Studies dating from the 1940s have demonstrated that commodities are often stored even when their carrying costs are negative. Such an observation imply that there is more than speculation in commodity marketing. This paper attempts to incorporate the role of convenience stocks in commodity marketing. The intrinsic value of carrying convenience stocks referred to as convenience yield is incorporated in the commodity arbitrage.
