Economic Activity and Ecosystem Services in the North Saskatchewan River Basin
Creators: North Saskatchewan Watershed Alliance (NSWA)
Publisher: name: University of Alberta Library
Year: 2010

The objective of this study was to provide preliminary estimates of the value of services being provided by ecosystems and the value of economic activity for each of the sub-basins in the NRSB. The intent of this report is to provide some initial background information on the relative importance and values of economic activity and ecosystem services in each sub-basin. It is expected that, as the requirements for additional economic studies become apparent, this analysis will provide the foundations for future studies. (As cited in executive summary.)

description: Der Auf- und Ausbau der Ganztagsschulen hat in Nordrhein-Westfalen maßgeblich die Schullandschaft umgestaltet und das Aufwachsen von Kindern und Jugendlichen verändert. In Nordrhein-Westfalen sind mittlerweile 92 Prozent der Primarschulen mit einem Ganztagsbetrieb ausgestattet. Als ein Hauptmotiv, welches zum Ausbau von Ganztagsschulen geführt hat, ist der gesellschaftliche Wandel in Familien- und Erwerbsstrukturen zu nennen, wobei der Vereinbarkeit von Familie und Beruf eine besonders große Rolle zugeschrieben wird. Die offene Ganztagsschule (OGS) soll ein qualitativ hochwertiges Bildungs- und zugleich Betreuungsangebot sein und mit ihren Öffnungszeiten eine verlässliche Betreuung der Kinder erwerbstätiger Eltern gewährleisten und die Eltern in ihrer Erziehungsarbeit unterstützen.
Why only hole conductors can be superconductors
Creators: name: Hirsch, J. E.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The conventional theory of superconductivity says that charge carriers in a metal that becomes superconducting can be either electrons or holes. I argue that this is incorrect. In order to satisfy conservation of mechanical momentum and of entropy of the universe in the superconductor to normal transition in the presence of a magnetic field it is necessary that the normal state charge carriers are holes. I will also review the empirical evidence in favor of the hypothesis that all superconductors are hole superconductors, and discuss the implications of this for the search for higher $T_c$ superconductors.

description: We show how including attraction in interparticle interactions reverses the effect of fluctuations in ordering of a prototypical artificial frustrated system. Buckled colloidal monolayers exhibit the same ground state as the Ising antiferromagnet on a deformable triangular lattice, but it is unclear if ordering in the two systems is driven by the same geometric mechanism. By a real-space expansion we find that for buckled colloids bent stripes constitute the stable phase, whereas in the Ising antiferromagnet straight stripes are favored. For generic pair potentials we show that attraction governs this selection mechanism, in a manner that is linked to local packing considerations. This supports the geometric origin of entropy in jammed sphere packings and provides a tool for designing self-assembled colloidal structures.

Los Waika (Yanoama), indígenas del Alto Orinoco 1954-1974

Year: 1975

description: A fines de septiembre/comienzos de octubre de 1974 realicé un breve viaje informativo a la región de los Yanoama (Waika), en el curso superior del Orinoco en Venezuela. Durante este viaje tuve oportunidad de recolectar nuevas e interesantes impresiones sobre la situación cultural actual de estos indígenas, que pude estudiar detenidamente hace unos veinte años atrás. Resulta que la generación más antigua e intermedia, y en parte también la más nueva, incluso en la proximidad inmediata de los centros de misiones que en el intertanto fueron levantados allí, siguen interiormente adictas a la antigua cultura, a pesar de que su forma de vida externa en parte ha experimentado cambios considerables. La innovación más importante es el creciente conocimiento de la lengua española; una vez que los niños que asisten a las escuelas de las misiones hayan crecido, a fines de este siglo habrá desaparecido la coexistencia de tradiciones indígenas y civilización moderna, y los yanoama del curso superior del Orinoco se habrán integrado al medio venezolano.

description: We measure the transport properties of two-dimensional ultracold Fermi gases during transverse demagnetization in a magnetic field gradient. Using a phase-coherent spin-echo sequence, we are able to distinguish bare spin diffusion from the Leggett-Rice effect, in which demagnetization is slowed by the precession of spin current around the local magnetization. When the two-dimensional scattering length is tuned to be comparable to the inverse Fermi wave vector $k_F^{-1}$, we find that the bare transverse spin diffusivity reaches a minimum of $1.7(6)\hbar/m$, where $m$ is the bare particle mass. The rate of demagnetization is also reflected in the growth rate of the s-wave contact, observed using time-resolved spectroscopy. At unitarity, the contact rises to $0.28(3) k_F^2$ per particle, measuring the breaking of scaling symmetry. Our observations support the conjecture that in systems with strong scattering, the local relaxation rate is bounded from above by $k_B T/\hbar$.
Indianerpolitik und katholische Mission in Brasilien im 19. und 20. Jahrhundert
Creators: name: Prien, Hans-Jürgen
Publisher: name: INDIANA
Year: 1975

description: Después de la elevación del Brasil a la condición de un reino (1808) respectivamente a un imperio después de la independencia (1822) la política indigenista pasó a ser todavía menos escrupulosa que en la época colonial. Con la creciente escasez de mano de obra a causa del fin del comercio de esclavos negros los indios nuevamente se consideraron como reserva de mano de obra. La Iglesia Católica era casi impotente frente al problema de la explotación de los indios sea por falta de concientización sea por causa de su absoluta dependencia del Estado bajo el régimen del patronado. En vista de la profunda crisis del monasticismo en el Brasil, capuchinos italianos sin ninguna experiencia en el campo de la misión entre los indios fueron llamados por parte del Gobierno brasileño para catequizar y civilizar a los indios. En el año de 1908 cuando el peligro de grandes matanzas de indios aumento cada vez más, antiguos colaboradores de Candido Mariano da Silva (Rondón), entonces miembros del Museo Nacional, alertaron la conciencia de la nación y lograron la institución del Servicio de Protección del Indio (1910- 1967) que particularmente bajo la dirección de Rondón hizo mucho bien pero a la larga no pudo detener los intereses económicos de la sociedad brasileña y finalmente fue a ser víctima de una corrupción funesta así que el número total de indios disminuyó en este medio siglo de medio millón a menos de cien mil.

La momia peruana. De las obras postumas, editado por Gerdt Kutscher
Creators: name: Uhle, Max
Publisher: name: INDIANA
Year: 1975

description: Para dar una idea del carácter y significado de la antigua momia peruana, es necesario definir brevemente las diversas formas de sepultura. Un abundante material informativo para este propósito lo constituyen los grandes cementerios excavados por Max Uhle en el año 1896 en Pachacamac, con sus cámaras o recintos mortuorios, situados a diferentes niveles de profundidad y procedentes de una serie de épocas culturales consecutivas. En la sepultura se observó el mayor cuidado, afanándose por conservar intacto el cuerpo del muerto. Una de las técnicas de momificación más importantes debe haber consistido en deshidratar el cadáver con ayuda del fuego: un proceso relativamente demoroso, que daba el tiempo necesario para la confección de las numerosas ofrendas fúnebres. La posición encuclillada de los sepultados, observada a menudo, corresponde a la manera de sentarse indígena, practicada aún hoy en día, de modo que el muerto se encuentra en el samawasi, "casa del descanso". Para la supervivencia en el más allá, el alma no sólo requiere "dinero", que le es entregado en forma de una pequeña pieza de metal colocada en la boca, sino, sobre todo, ropa y las semillas necesarias para levantar nuevos cultivos. El culto funerario, altamente desarrollado tanto en la costa peruana como en el altiplano, era sobre todo un culto a los antepasados, cuya bendición revestía la mayor importancia para los sobrevivientes.

Static structure of chameleon dark Matter as an explanation of dwarf spheroidal galactic core

description: We propose a novel mechanism which explains cored dark matter density profile in recently observed dark matter rich dwarf spheroidal galaxies. In our scenario, dark matter particle mass decreases gradually as function of distance towards the center of a dwarf galaxy due to its interaction with a chameleon scalar. At closer distance towards galactic center the strength of attractive scalar fifth force becomes much stronger than gravity and is balanced by the Fermi pressure of dark matter cloud, thus an equilibrium static configuration of dark matter halo is obtained. Like the case of soliton star or fermion Q-star, the stability of the dark matter halo is obtained as the scalar achieves a static profile and reaches an asymptotic value away from the galactic center. For simple scalar-dark matter interaction and quadratic scalar self interaction potential, we show that dark matter behaves exactly like cold dark matter (CDM) beyond few $\rm{kpc}$ away from galactic center but at closer distance it becomes lighter and fermi pressure cannot be ignored anymore. Using Thomas-Fermi approximation, we numerically solve the radial static profile of the scalar field, fermion mass and dark matter energy density as a function of distance. We find that for fifth force mediated by an ultra light scalar, it is possible to obtain a flattened dark matter density profile towards galactic center. In our scenario, the fifth force can be neglected at distance $ r \geq 1\, \rm{kpc}$ from galactic center and dark matter can be simply treated as heavy non-relativistic particles beyond this distance, thus reproducing the success of CDM at large scales.

Das Atarco-Fragment (Süd-Peru). Ein Beitrag zum Tiahuanaco-Problem

Publisher: name: INDIANA
Year: 1975

description: El presente trabajo es un intento de interpretación de los diseños reproducidos en el fragmento de un tapiz procedente del sector de Atareo en el valle de Taruga, al Sur del Perú. Dos de los campos cuadriculados muestran una deidad que - como lo prueba una comparación con las pinturas de las cerámicas de Moche - ha de ser considerada el dios de la luna en su barca de serpiente, habiéndose reproducido los elementos adoptados de la costa norteña en los colores de la variante Tiahuanaco-Costeña. En otros dos cuadriculados aparece en cambio una figura mítica en forma de serpiente, que hace pensar en relaciones culturales considerablemente más extensas: aquí la serpiente emplumada, bien conocida en el antiguo arte mexicano, para la cual se citan ejemplos de Cholula, Xochicalco y Chichón Itzá. El fragmento de Atareo contiene asimismo el jeroglífico Colhuacán ("cerro encorvado"), de los códices mexicanos. Por consiguiente, sólo puede tratarse de portadores de antiguas culturas mexicanas, arribados a la costa sur del Perú, y cuya huella se denota en el tejido, a clasificarse en la segunda mitad del primer milenio D.C. Si bien es necesario recalcar el carácter hipotético de las interpretaciones dadas aquí, cabe sostener que en el fragmento de Atareo la representación de una figura tan eminentemente mexicana como la serpiente emplumada aparece junto a motivos del arte Moche, en un tejido polícromo.

description: Deep Neural Networks are becoming the de-facto standard models for image understanding, and more generally for computer vision tasks. As they involve highly parallelizable computations, CNN are well suited to current fine grain programmable logic devices. Thus, multiple CNN accelerators have been successfully implemented on FPGAs. Unfortunately, FPGA resources such as logic elements or DSP units remain limited. This work presents a holistic method relying on approximate computing and design space exploration to optimize the DSP block utilization of a CNN implementation on an FPGA. This method was tested when implementing a reconfigurable OCR convolutional neural network on an Altera Stratix V device and varying both data representation and CNN topology in order to find the best combination in terms of DSP block utilization and classification accuracy. This exploration generated dataflow architectures of 76 CNN topologies with 5 different fixed point representation. Most efficient implementation performs 883 classifications/sec at 256 x 256 resolution using 8% of the available DSP blocks.

description: We study the bond-alternating Heisenberg model using the finite-size density-matrix renormalization group (DMRG) technique and analytical arguments based on the matrix product state, where we pay particular attention to the boundary-condition dependence on the entanglement spectrum of the system. We show that, in the antiperiodic boundary condition (APBC), the parity quantum numbers are equivalent to the topological invariants characterizing the topological phases protected by the bond-centered inversion and $π$ rotation about $z$ axis. We also show that the odd parity in the APBC, which characterizes topologically nontrivial phases, can be extracted as a two-fold degeneracy in the entanglement spectrum even with finite system size. We then determine the phase diagram of the model with the uniaxial single-ion anisotropy using the level spectroscopy method in the DMRG technique. These results not only suggest the detectability of the symmetry protected topological (SPT) phases via general twisted boundary conditions but also provide a useful and precise numerical tool for discussing the SPT phases in the exact diagonalization and DMRG techniques.

description: Using test particle simulations we study particle acceleration at highly perpendicular ($θ_{Bn}\geq 75^\circ$) shocks under conditions of modeling magnetic turbulence. We adopt a backward-in-time method to solve the Newton-Lorentz equation using the observed shock parameters for quasi-perpendicular interplanetary shocks, and compare the simulation results with $ACE$/EPAM observations to obtain the injection energy and timescale of particle acceleration. With our modeling and observations we find that a large upstream speed is responsible for efficient particle acceleration. Our results also show that the quasi-perpendicular shocks are capable of accelerating thermal particles to high energies of the order of MeV for both kappa and Maxwellian upstream distributions, which may originate from the fact that in our model the local background magnetic field has a component parallel to the shock normal.

Transitions in optimal adaptive strategies for populations in fluctuating environments

description: Biological populations are subject to fluctuating environmental conditions. Different adaptive strategies can allow them to cope with these fluctuations: specialization to one particular environmental condition, adoption of a generalist phenotype that compromise between conditions, or population-wise diversification (bet-hedging). Which strategy provides the largest selective advantage in the long run depends on the range of accessible phenotypes and the statistics of the environmental fluctuations. Here, we analyze this problem in a simple mathematical model of population growth. First, we review and extend a graphical method to identify the nature of the optimal strategy when the environmental fluctuations are uncorrelated. Temporal correlations in environmental fluctuations open up new strategies that rely on memory but are mathematically challenging to study: we present here new analytical results to address this challenge. We illustrate our general approach by analyzing optimal adaptive strategies in the presence of trade-offs that constrain the range of accessible phenotypes. Our results extend several previous studies and have applications to a variety of biological phenomena, from antibiotic resistance in bacteria to immune responses in vertebrates.

description: Seedlings derived from two Ohio buckeyes (Aesculus glabra Willd.) trees, the National Champion growing in Illinois, USA, and the Ohio State Champion were sampled. The National Champion grows at the northern limits of the species’ native range. The Ohio State Champion grows in Huron County, Ohio, well within the eastern range of the species. We also sampled 40 adult trees growing in Ohio and Illinois. All trees were genotyped at six microsatellite loci. We found that 42 of the 44 sampled seedlings (95%) from the National Champion tree, collected over two seasons, exhibited only maternal alleles at all six microsatellite loci, indicating they were produced by self-fertilization. In contrast, all seedlings from the Ohio state champion tree (N = 48) exhibited non-maternal alleles, indicating they were produced by outcrossing. Our results suggest that when outcross pollen is not available, A. glabra will self-fertilize, but does so rarely or never when outcross pollen is available. Seed germination and early survival were similar for progeny of both champions, but seedlings from the National Champion show lower growth rates and higher mortality during a spring frost, possibly due to inbreeding depression. There was little evidence for genetic structure between trees sampled in Ohio and Illinois.

description: Unmanned aerial vehicles (UAVs) can be used to provide wireless network and remote surveillance coverage for disaster-affected areas. During such a situation, the UAVs need to return periodically to a charging station for recharging, due to their limited battery capacity. We study the problem of minimizing the number of UAVs required for a continuous coverage of a given area, given the recharging requirement. We prove that this problem is NP-complete. Due to its intractability, we study partitioning the coverage graph into cycles that start at the charging station. We first characterize the minimum number of UAVs to cover such a cycle based on the charging time, the traveling time, and the number of subareas to be covered by the cycle. Based on this analysis, we then develop an efficient algorithm, the cycles with limited energy algorithm. The straightforward method to continuously cover a given area is to split it into N subareas and cover it by N cycles using N additional UAVs. Our simulation results examine the importance of critical system parameters: the energy capacity of the UAVs, the number of subareas in the covered area, and the UAV charging and traveling times.We demonstrate that the cycles with limited energy algorithm requires 69%-94% fewer additional UAVs relative to the straightforward method, as the energy capacity of the UAVs is increased, and 67%-71% fewer additional UAVs, as the number of subareas is increased.

description: El dios más antiguo de Teotihuacán es representado antropomórficamente sólo en esculturas de piedra y unas cuantas figurillas de barro que muestran un anciano con un recipiente sobre la cabeza, destinado a quemar incienso. Sin embargo, diversas formas gráficas o signos ostentan los parafernales rituales relacionados con esta deidad paternalista del fuego. Tales signos, a menudo, se combinan con imágenes de los diferentes aspectos del dios de la lluvia, que predominan en el arte de Teotihuacán. Con el surgimiento de deidades adicionales del fuego durante la era postclásica tardía, las interrelaciones de Xiuhtecutli, el sucesor del viejo dios del fuego Huehueteotl, con deidades de la lluvia se evidencian iconográficamente en los manuscritos pictográficos y en las esculturas. Finalmente, se puede decir que, si bien en Teotihuacán la imaginería del culto al dios de la lluvia ensombreció el culto al dios del fuego, este último no se eclipsó del todo aunque el reconocimiento de su importancia se vio disminuido en gran parte por la falta de comprensión de su simbolismo. La identificación e interpretación de los signos del culto al dios del fuego indujo a la revaluación de un signo compuesto - el grupo de los cuatro elementos - y a un intento de extractar una fórmula mnemónica de oración de las características peculiares atribuidas a estos cuatro signos. En consecuencia, cabe deducir que el desarrollo de las formas gráficas de Teotihuacán alcanzó la fase incipiente de un sistema parcial de escritura.

description: We present a detailed study of the phase diagram of copper intercalated TiSe$_2$ single crystals, combining local Hall-probe magnetometry, tunnel diode oscillator technique (TDO), specific-heat, and angle-resolved photoemission spectroscopy measurements. A series of the Cu$_x$TiSe$_2$ samples from three different sources with various copper content $x$ and superconducting critical temperatures $T_c$ have been investigated. We first show that the vortex penetration mechanism is dominated by geometrical barriers enabling a precise determination of the lower critical field, $H_{c1}$. We then show that the temperature dependence of the superfluid density deduced from magnetic measurements (both $H_{c1}$ and TDO techniques) clearly suggests the existence of a small energy gap in the system, with a coupling strength $2Δ_s \sim [2.4-2.8]k_BT_c$, regardless of the copper content, in puzzling contradiction with specific heat measurements which can be well described by one single large gap $2Δ_l \sim [3.7-3.9]k_BT_c$. Finally, our measurements reveal a non-trivial doping dependence of the condensation energy, which remains to be understood.

Aztekische Reinkarnationsvorstellungen aus der Sicht neuerer ethnographischer Daten
Creators: name: Köhler, Ulrich
Publisher: name: INDIANA
Year: 1977

description: Recientemente, investigadores mexicanos han llamado la atención sobre ciertas indicaciones para una creencia azteca en una reencarnación. Revisando las fuentes tempranas, León-Portilla llego a la conclusión que estas ideas eran nada más que brotes ideológicos que no lograron prevalecer en el pensamiento religioso náhuatl, que persistió aferrado a la idea de que esta vida es una experiencia única. A recientes investigaciones etnográficas debemos el conocimiento que el concepto de reencarnación no es una idea marginal en el pensamiento religioso de algunos grupos de indígenas mesoamericanos, sino un aspecto típico. En unión con datos sobre las creencias de los antiguos nicaraos las informaciones actuales, proviniendo de varios grupos lingüísticos separados por grandes distancias geográficas, sugieren la conclusión que las ideas acerca de una reencarnación no eran brotes ideológicos desarrollados por los aztecas, sino conceptos mucho más antiguos. Además, las noticias etnográficas nos dan la información que no hay contradicción entre el concepto de la reencarnación del alma y la idea que la vida humana es una experiencia única, porque el concepto de metempsicosis como lo conocemos de indígenas mesoamericanos no contiene la idea de un renacimiento del ser humano individual. Una posible influencia cristiana puede ser desechada de antemano, ya que se parte de criterios totalmente diferentes, como lo prueba la creencia en una transformación animal y que la reencarnación ocurre bajo sexo diferente y en otro lugar.

description: We consider the exclusive $P_{\ell 4}$ decays, $P\to (P_1P_2)_V\ell ν_{\ell}$, where the subindex $V$ means that the invariant mass of the pseudoscalar pair is taken within a small window around the mass of the vector meson $V$. Pole contributions beyond the dominant $P\to V(\to P_1P_2)\ellν_{\ell}$ amplitude of $P_{\ell 4}$ decays are identified, which, in turn, affects the determination of the CKM matrix elements $|V_{qq'}|$. We evaluate the effects of those contributions in the extraction of bottom and charm quark mixings. An application to $B\to (ππ)_ρ\ell ν_{\ell}$ data from Belle collaboration, shows an increase in the extracted value of $|V_{ub}|$ in better agreement with determinations based on $B\to π\ellν_{\ell}$ decays. The effect of the $ρ$ and $D^*$ pole contributions in the determination of $|V_{cd}|$ from the decay $D\to ππ\ell^- \barν_{\ell}$, has been also investigated.

Héraldique européenne et manuscrits pictographiques mexicains
Creators: name: Galarza, Joaquín
Publisher: name: INDIANA
Year: 1977

description: En algunos manuscritos pictóricos mexicanos de la  época colonial, aparecen motivos inspirados en las convenciones plásticas de la heráldica europea. Los tlacuilos toman elementos o blasones completos y les dan otro significado, adaptándolos al sistema tradicional indígena, en el que existía una codificación simbólica y emblemática comparable a la de Europa. En este artículo se estudian varios ejemplos de blasones reales, en seis códices de distintas fechas, del siglo XVI al XVIII, empleados para simbolizar sendos documentos de tierras comunales: Cédulas o Cartas reales, que daban derechos de propiedad de la tierra a los pueblos de indios.

Non-Farm and Off-Farm Activities in Achieving Livelihood Security in the Amhara Region: Case Study of Lay Gayint District
Creators: name: Berlie, Arega Bazezew
Publisher: name: Journal of Agriculture and Environmental Sciences
Year: 2019

description: In areas where agricultural activities are highly limited because of unpredictable rainfall, land degradation and recurrent drought, livelihood diversification can increase households’ income and food security. However, a range of factors from physical environmental circumstances to policy and institutions related issues determine households’ participation in non/off-farm activities in the study area. The general objective of the study was to identify factors that determine households’ participation in non/off-farm activities in drought- prone areas of the Amhara Region using Lay Gayint district as a case study site. Questionnaire survey, in-depth interview and focus group discussions were the major data collection techniques. Both qualitative and quantitative research methods were used for data analysis and the later included descriptive statistics and regression modeling. A major finding is that despite the low level of productivity related to local environmental constraints, rural livelihoods remain undiversified with small-scale rain-fed agriculture providing the primary source of livelihood for the large majority of sample households. Only small percentage of respondents (25%) participated in some form of non-farm/off-farm activities, with little contributions to their sources of income. The study found out that non/off-farm activities that meet the shortfall of consumption needs such as selling charcoal and fuel wood, causal labor and out migration were the major sources of income for the poor and vulnerable households. The study forwarded that improving livelihood security of rural households in the study area requires integrated development interventions aimed at improved natural resources management and livelihood diversification including interventions in the area of non-farm employment opportunities and skill trainings at household level.
