description: Magnetism is one of the four fundamental forces. However, the origin of magnetic fields in stars, galaxies and clusters is an open problem in astrophysics and fundamental physics. When and how were the first fields generated? Are present-day magnetic fields a result of dynamo action, or do they represent persistent primordial magnetism? What role do magnetic fields play in turbulence, cosmic ray acceleration and galaxy formation? Here we demonstrate how the Square Kilometer Array (SKA) can deliver new data which will directly address these currently unanswered issues. Much of what we present is based on an all-sky survey of rotation measures, in which Faraday rotation towards >10^7 background sources will provide a dense grid for probing magnetism in the Milky Way, in nearby galaxies, and in distant galaxies, clusters and protogalaxies. Using these data, we can map out the evolution of magnetised structures from redshifts z>3 to the present, can distinguish between different origins for seed magnetic fields in galaxies, and can develop a detailed model of the magnetic field geometry of the intergalactic medium and of the overall Universe. With the unprecedented capabilities of the SKA, the window to the Magnetic Universe can finally be opened.

Shower Power: Isolating the Prompt Atmospheric Neutrino Flux Using Electron Neutrinos

description: At high energies, the very steep decrease of the conventional atmospheric component of the neutrino spectrum should allow the emergence of even small and isotropic components of the total spectrum, indicative of new physics, provided that they are less steeply decreasing, as generically expected. One candidate is the prompt atmospheric neutrino flux, a probe of cosmic ray composition in the region of the knee as well as small-$x$ QCD, below the reach of collider experiments. A second is the diffuse extragalactic background due to distant and unresolved AGNs and GRBs, a key test of the nature of the highest-energy sources in the universe. Separating these new physics components from the conventional atmospheric neutrino flux, as well as from each other, will be very challenging. We show that the charged-current {\it electron} neutrino "shower" channel should be particularly effective for isolating the prompt atmospheric neutrino flux, and that it is more generally an important complement to the usually-considered charged-current {\it muon} neutrino "track" channel. These conclusions remain true even for the low prompt atmospheric neutrino flux predicted in a realistic cosmic ray scenario with heavy and varying composition across the knee (Candia and Roulet, 2003 JCAP {\bf 0309}, 005). We also improve the corresponding calculation of the neutrino flux induced by cosmic ray collisions with the interstellar medium.

description: Motivated by a scenario of magnetogenesis in which a homogeneous magnetic field is generated during inflation, we study the magnetohydrodynamic evolution of the primordial plasma motions for two kinds of initial conditions -- (i) a spatially homogeneous field with an unlimited correlation length, and (ii) a zero flux scale-invariant statistically homogeneous magnetic field. In both cases, we apply, for a short initial time interval, monochromatic forcing at a certain wave number so that the correlation length is finite, but much smaller than the typical length scale of turbulence. In particular, we investigate the decay of nonhelical and helical hydromagnetic turbulence. We show that, in the presence of a homogeneous magnetic field, the decay of helical and nonhelical small-scale fields can occur rapidly. This is a special property of a system with a perfectly homogeneous magnetic field, which is sometimes considered as a local approximation to a slowly varying background field. It can never change and acts as an imposed magnetic field. This is in a sharp contrast to the case of a statistically homogeneous magnetic field, where we recover familiar decay properties: a much slower decay of magnetic energy and a faster growth of the correlation length, especially in the case with magnetic felicity. The result suggests that a homogeneous magnetic field, if generated during inflation, should persist under the influence of small-scale fields and could be the origin of the large-scale magnetic field in the Universe.

description: Studies were conducted to determine the effect of five rootstocks on premature fruit drop'of Parvin and Tommy Atkins, mango varieties. It was found that the number of premature fruit drop as well as the index and percentage of premature drop were on average higher for the Parvin variety. In both varieties the number of premature fruits dropped was determined by the rootstocks as well as by the degree of development of the fruit, whereas, the fruit drop index and«the percentage of fruit drop were influenced by the rootstock and by the degree of fruit development, respectively. No significant variation in percentage of fruit drop was observed among rootstocks.

description: Black holes are known to launch powerful relativistic jets and emit highly variable gamma radiation. How these jets are loaded with plasma remains poorly understood. Spark gaps are thought to drive particle acceleration and pair creation in the black-hole magnetosphere. In this paper, we perform 2D axisymmetric general-relativistic particle-in-cell simulations of a monopole black-hole magnetosphere with a realistic treatment of inverse Compton scattering and pair production. We find that the magnetosphere can self-consistently fill itself with plasma and activate the Blandford-Znajek mechanism. A highly time-dependent spark gap opens near the inner light surface which injects pair plasma into the magnetosphere. These results may account for the high-energy activity observed in active galactic nuclei and explain the origin of plasma at the base of the jet.

description: An experiment was performed at the Juana Diaz Agricultural Experiment Substation in a San Anton Soil (Cumulic Haplustolls). The objective of the study project was to evaluate the effect of inorganic nitrogen and chicken manure applications in the yield components of papaya (Carica papaya L.). Growth data from the papaya plants was collected at'3, 6 and 12 months after planting. The parameters evaluated were: stem diameter, height, number of leaves/plant, and the reproductive column of the papaya plants. Data was taken on number of fruits and yield. A significant effect was observed, as for the nitrogen treatments for number of fruits and yield. Manure applications significantly increased vigour and plant growth.

description: We demonstrate through experiments and numerical simulations that low-density, low-loss, meter-scale plasma channels can be generated by employing a conditioning laser pulse to ionize the neutral gas collar surrounding a hydrodynamic optical-field-ionized (HOFI) plasma channel. We use particle-in-cell simulations to show that the leading edge of the conditioning pulse ionizes the neutral gas collar to generate a deep, low-loss plasma channel which guides the bulk of the conditioning pulse itself as well as any subsequently injected pulses. In proof-of-principle experiments we generate conditioned HOFI (CHOFI) waveguides with axial electron densities of $n_\mathrm{e0} \approx 1 \times 10^{17} \; \mathrm{cm^{-3}}$, and a matched spot size of $26 \; \mathrm{μm}$. The power attenuation length of these CHOFI channels is $L_\mathrm{att} = (21 \pm 3) \; \mathrm{m}$, more than two orders of magnitude longer than achieved by HOFI channels. Hydrodynamic and particle-in-cell simulations demonstrate that meter-scale CHOFI waveguides with attenuation lengths exceeding 1 m could be generated with a total laser pulse energy of only $1.2$ J per meter of channel. The properties of CHOFI channels are ideally suited to many applications in high-intensity light-matter interactions, including multi-GeV plasma accelerator stages operating at high pulse repetition rates.

description: The phase diagram of hole-doped copper oxides shows four different electronic phases existing at zero temperature. Familiar among these are the Mott insulator, high-transition-temperature superconductor and metallic phases. A fourth phase, ofunknown identity, occurs at light doping along the zero-temperature bound of the `pseudogap' regime. This regime is rich in peculiar electronic phenomena, prompting numerous proposals that it contains some form of hidden electronic order. Here we present low-temperature electronic structure imaging studies of a lightly hole-doped copper oxide: Ca_{2-x}Na_{x}CuO_{2}Cl_{2}. Tunnelling spectroscopy (at energies |E|>100 meV) reveals electron extraction probabilities greatly exceeding those for injection, as anticipated for a doped Mott insulator. However, for |E|<100 meV, the spectrum exhibits a V-shaped energy gap centred on E=0. States within this gap undergo intense spatial modulations, with the spatial correlations of a four CuO_{2}-unit-cell square checkerboard, independent of energy. Intricate atomic-scale electronic structure variations also exist within the checkerboard. These data are consistent with an unanticipated crystalline electronic state, possibly the hidden electronic order, existing in the zero-temperature pseudogap regime of Ca_{2-x}Na_{x}CuO_{2}Cl_{2}.

description: A fundamental understanding of the photoexcited carrier system in diamond is crucial to facilitate its application in photonic and electronic devices. Here, we studied the detailed balance between free carriers and excitons in pristine diamond by using a deep-ultraviolet (DUV) pump in combination with terahertz (THz) probe spectroscopy. We investigated the transformation of photoexcited carriers to excitons via an internal transition of excitons, which was newly found to occur at a frequency of approximately 15 THz. We determined the equilibrium constant in the Saha equation from the temperature dependence of the free-carrier density measured at chemical equilibrium. The derived exciton binding energy was larger than the conventional value, which indicated an energy shift due to the fine-structure splitting of the exciton states.

description: We prove a $p$-adic analogue of the André-Oort conjecture for subvarieties of the universal abelian varieties containing a dense set of special points. Let $g$ and $n$ be integers with $n \geq 3$ and $p$ a prime number not dividing $n$. Let $R$ be a finite extension of $W[{\mathbb F}_p^{\mathrm alg}]$, the ring of Witt vectors of the algebraic closure of the field of $p$ elements. The moduli space $\cA = \cA_{g,1,n}$ of $g$-dimensional principally polarized abelian varieties with full level $n$-structure as well as the universal abelian variety $π:\cX \to \cA$ over $\cA$ may be defined over $R$. We call a point $ξ\in \cX(R)$ \emph{$R$-special} if $\cX_{π(ξ)}$ is a canonical lift and $ξ$ is a torsion point of its fibre. We show that an irreducible subvariety of $\cX_R$ containing a dense set of $p$-special points must be a special subvariety in the sense of mixed Shimura varieties. Our proof employs the model theory of difference fields.

description: We present a complete description of spin injection and detection in Fe/Al_xGa_{1-x}As/GaAs heterostructures for temperatures from 2 to 295 K. Measurements of the steady-state spin polarization in the semiconductor indicate three temperature regimes for spin transport and relaxation. At temperatures below 70 K, spin-polarized electrons injected into quantum well structures form excitons, and the spin polarization in the quantum well depends strongly on the electrical bias conditions. At intermediate temperatures, the spin polarization is determined primarily by the spin relaxation rate for free electrons in the quantum well. This process is slow relative to the excitonic spin relaxation rate at lower temperatures and is responsible for a broad maximum in the spin polarization between 100 and 200 K. The spin injection efficiency of the Fe/Al_xGa_{1-x}As Schottky barrier decreases at higher temperatures, although a steady-state spin polarization of at least 6 % is observed at 295 K.

description: The concept of sustainable development emerged as a consequence to a growing awareness of the global environmental crisis. People all over the world are working towards sustainable development. In addition to environmental criteria, quality of life is an important indicator of the health of a city. Urban parks fulfill many social functions and address the psychological needs of citizens, making them a very valuable resource and a key ingredient for a sustainable city. Despite many challenges, countries like India are slowly adopting measures to increase sustainability within their cities. Located in the South Indian city of Bangalore, Cariappa Park is a small urban park. In its present state, it fails to live up to its role as a provider of social, ecological and economic services to its users. In this study, an attempt is made to look into the factors that have led to the failure of this park. The study further proposes an alternative design for the park. The aim of the proposed design is to inspire environmental consciousness and sustainable design construction through example. The new design will fulfill many social, economic and environmental functions, rendering Cariappa Park into a valuable municipal resource that contributes to the well-being of its citizens and to the sustainability of the city of Bangalore.

description: A class of Aubry-André-Harper models of spin-orbit coupled electrons exhibits a topological phase diagram where two regions belonging to the same phase are split up by a multicritical point. The critical lines which meet at this point each defines a topological quantum phase transition with a second-order nonanalyticity of the ground-state energy, accompanied by a linear closing of the spectral gap with respect to the control parameter; except at the multicritical point which supports fourth-order transitions with parabolic gap-closing. Here both types of criticality are characterized through a scaling analysis of the curvature function defined from the topological invariant of the model. We extract the critical exponents of the diverging curvature function at the non-high symmetry points in the Brillouin zone where the gap closes, and also apply a renormalization group approach to the flattening curvature function at high symmetry points. We also derive a basis-independent correlation function between Wannier states to characterize the transition. Intriguingly, we find that the critical exponents and scaling law defined with respect to the spectral gap remain the same regardless of the order of the transition.

description: We study the rare top decays $t\to c l_{i} l_{j}(l=τ,μ,or e)$ in the framework of topcolor-assisted technicolor($TC2$) models. We find that the neutral top-pion $π_{t}^{0}$ can produce significant contributions to these processes via the flavor changing couplings $π_{t}^{0} \bar{t} c$ and $π_{t}^{0} l_{i} l_{j}$. For the $π_{t}^{0}$ mass $m_{π_{t}}=150 GeV$ and the parameter $ε=0.08$, the branching ratio $Br$(t$\to c ττ)$ can reach $7.1\times10^{-7}$. Taking into account the constraints of the present experimental limit of the process $μ\to e γ$ on the free parameters of $TC2$ models, we find that the value of $Br$($t\to c τμ$)$\approx$$Br$($t\to c τe$) is in the range of 1.8$\times10^{-10}\sim1.7\times10^{-8}$.

description: The initial orbits of infalling subhalos largely determine the subsequent evolution of the subhalos and satellite galaxies therein and shed light on the assembly of their hosts. Using a large set of cosmological simulations of various resolutions, we quantify the orbital distribution of subhalos at infall time and its mass and redshift dependence in a large dynamic range. We further provide a unified and accurate model validated across cosmic time, which can serve as the initial condition for semi-analytic models. We find that the infall velocity $v$ follows a nearly universal distribution peaked near the host virial velocity $V_{\mathrm{h}}$ for any subhalo mass or redshift, while the infall orbit is most radially biased when $v\sim V_{\mathrm{h}}$. Moreover, subhalos that have a higher host mass or a higher sub-to-host ratio tend to move along a more radial direction with a relatively smaller angular momentum than their low host mass or low sub-to-host ratio counterparts, though they share the same normalized orbital energy. These relations are nearly independent of the redshift when using the density peak height as the proxy for host halo mass. The above trends are consistent with the scenario where the dynamical environment is relatively colder for more massive structures because their own gravity is more likely to dominate the local potentials. Based on this understanding, the more massive or isolated halos are expected to have higher velocity anisotropy.

description: As a continuation of our previous works studying the holographic principle in the plane-wave limit, we discuss the 3-point correlation functions of BMN operators with bosonic excitations when impurities are not conserved. We show that our proposal for a holographic mapping between the conformal OPE coefficients of super Yang-Mills theory and the 3-point vertex of the holographic string field theory is valid to the leading order in the large $μ$ limit. Our results provide for the first time a direct holographic relation for the 3-point correlators of BMN operators including impurity non-preserving processes.

description: The optical conductivity $σ_{1}(ω)$ of Eu$_{1-x}$Ca$_{x}$B$_{6}$ has been obtained from reflectivity and ellipsometry measurements for series of compositions, $0\leq x\leq 1$. The interband part of $σ_{1}(ω) $ shifts continuously to higher frequency as Ca-content $x$ increases. Also the intraband spectral weight of $σ_{1}(ω)$ decreases rapidly and essentially vanishes for $x\geq x_{c}=0.35$. These results show that the valence band and the conduction band of Eu$_{1-x}$Ca$_{x}$B$_{6}$ move away from each other such that their band overlap decreases with increasing Ca-substitution. As a result, the electronic state evolves from the semimetallic structure of EuB$_{6}$ to the insulating CaB$_{6}$ where the two bands are separated to open a finite gap ($\simeq 0.25$ eV) at the X-point of the Brillouin zone.

description: El cultivo de arroz en Republica Dominicana ocupa una &rea aproximadamente de 104,000 ha, divididas en varias zonas o regiones con diferentes condiciones tanto de suelo como de clima. El uso intensivo de los suelos arroceros combinados con varias practicas agricola tales como quema de los residuos, preparacion del suelo en humedo, entre otras, esta dando como resultados una mayor degradacion de los suelos arroceros, quedando como unica opcion al productor el aumento en la cantidad de fertilizantes a usar por cosecha. Segun, SOIL SCIENCE SOCIETY OF AMERICA, el termino de materia organica se define "fraction organica del suelo que incluye residuos vegetales y animales en diferentes estados de descomposicion, tejidos y celulas de organismos que viven en el suelo y substantias producida por los habitantes del suelo". La materia organica conjuntamente con los minerales de arcillas son los dos agentes cementantes que mas contribuyen en agregacion del suelo, siendo la materia organica mas eficiente que las arcillas en la formation de agregados estables. La incorporation de materia organica en el suelo provoca una mayor actividad de los microorganismo, los cuales son los responsables directa o indirectamente por la disponibilidad de los nutrientes en el suelos. Con el objetivo Evaluar el efecto de la aplicacidn de humus liquidos conjuntamente con la reduccion de fertilizantes con relacidn a la nutrition de la planta de arroz, fue conducidos un experimento de campo, en el Centro de Investigacidn Arroceras (CEDIA) ubicado en Juma, Bonao, Republica Dominicana. Los tratamientos estudiados correspondieron a la combinacidn de las dosis de humus liquidos de 0, 8 y 12 Loha-1 , ademas de la reduccion de 0.15 y 30 % de la fertilizantes comun recomendada por el CEDIA. Los resultados obtenidos de los rendimientos, muestran que los mejores tratamientos resultaron de la aplicacidn de fertilizantes comun combinada con la aplicacidn de humus liquidos en 8 y 12 Loha-1 con un aumento de los rendimientos en el orden de 21.5 y 18.7 % respectivamente, siendo estadisticamente superiores a la fertilization comun, que reporto una media de 4,156.3 kgoha-1. El mejor comportamientos de la planta resulto cuando se reducia la fertilization comun en 15 % combinada con la aplicacidn de humus liquidos en dosis de 8 Loha-1.

We prove that both the cohomology of an injective hemistrict Lie 2-algebra $L$ and the cohomology of the semistrict Lie 2-algebra obtained from skew-symmetrization of $L$ are isomorphic to the Chevalley-Eilenberg cohomology of the induced Lie algebra $L_{\operatorname{Lie}}$.

title: Aspect-Oriented Music Representation
Creators: name: Hill, Patrick
Publisher: name: The Open University
Year: 2007

description: The composition of a musical work may be viewed as involving the exploitation, through various combinations, transformations and arrangements, of a finite set of compositional processes and musical materials. As a consequence, combinatorial and transformational processes and musical materials across various musical dimensions tend to be scattered throughout a musical work. Although the processes involved in music composition vary widely between composers, and indeed between works, in general these processes tend to be iterative, with the composer creating and revising musical materials within and between different musical dimensions and concerns. When musical materials are modified, related musical structures must also be updated, in order to maintain musical coherence. However, in general, the relationships that exist between musical materials are not explicitly notated. Although for many composers this process may be unconscious, we hypothesize that tools for identifying, creating, organising, modifying and manipulating such related structures explicitly would have numerous applications for composers, teachers and analysts. The aim of the research described in this thesis is to find ways in which Aspect Oriented Programming (AOP), and cognate techniques, may be used to facilitate the development of computer systems that support musical composition by assisting in the separation, organisation and combination of musical concerns. We investigate the semantics of crosscutting within a musical context and use this to evolve an Aspect Oriented Music Representation (AOMR), and a concrete proof-of-concept implementation of AOMR called AspectMusic. AOMR demonstrates how two different, current approaches to AOP, namely symmetric and asymmetric, can be usefully applied to the separation, composition and conditional modification of musical structures. We also describe an approach, called Composition History, which provides a detailed history of the symmetric composition operations that have been applied to a structure and makes this information available within the asymmetric framework. In this way, details of the provenance of any given musical event may be used as part of the pointcut expression within asymmetric AOMR aspects. Additionally, we demonstrate a logic reification of AOMR events, including composition history, which permits declarative pointcut expressions.

description: We present the theory of weak gravitational lensing in cosmologies with generalized gravity, described in the Lagrangian by a generic function depending on the Ricci scalar and a non-minimally coupled scalar field. We work out the generalized Poisson equations relating the dynamics of the fluctuating components to the two gauge invariant scalar gravitational potentials, fixing the new contributions from the modified background expansion and fluctuations. We show how the lensing observables are affected by the cosmic expansion as well as by the presence of the anisotropic stress, which is non-null at the linear level both in scalar-tensor gravity and in theories where the gravitational Lagrangian term features a non-minimal dependence on the Ricci scalar. We derive the generalized expressions for the convergence power spectrum, and illustrate phenomenologically the new effects in Extended Quintessence scenarios, where the scalar field coupled to gravity plays the role of the dark energy.

description: During pandemic events, strategies such as social distancing can be fundamental to curb viral spreading. Such actions can reduce the number of simultaneous infections and mitigate the disease spreading, which is relevant to the risk of a healthcare system collapse. Although these strategies can be suggested, their actual implementation may depend on the population perception of the disease risk. The current COVID-19 crisis, for instance, is showing that some individuals are much more prone than others to remain isolated, avoiding unnecessary contacts. With this motivation, we propose an epidemiological SIR model that uses evolutionary game theory to take into account dynamic individual quarantine strategies, intending to combine in a single process social strategies, individual risk perception, and viral spreading. The disease spreads in a population whose agents can choose between self-isolation and a lifestyle careless of any epidemic risk. The strategy adoption is individual and depends on the perceived disease risk compared to the quarantine cost. The game payoff governs the strategy adoption, while the epidemic process governs the agent's health state. At the same time, the infection rate depends on the agent's strategy while the perceived disease risk depends on the fraction of infected agents. Results show recurrent infection waves, which were seen in previous epidemic scenarios with quarantine. Notably, the risk perception is found to be fundamental for controlling the magnitude of the infection peak, while the final infection size is mainly dictated by the infection rates. Low awareness leads to a single and strong infection peak, while a greater disease risk leads to shorter, although more frequent, peaks. The proposed model spontaneously captures relevant aspects of a pandemic event, highlighting the fundamental role of social strategies.

description: We predict that the Curie temperature of a ferromagnetic resonant tunneling diode will decrease abruptly, by approximately a factor of two, when the downstream chemical potential falls below the quantum well resonance energy. This property follows from elementary quantum transport theory notions combined with a mean field description of diluted magnetic semiconductor ferromagnetism. We illustrate this effect by solving coupled non-equilibrium Green's function, magnetic mean-field, and electrostatic Poisson equations self-consistently to predict the bias voltage and temperature dependence of the magnetization of a model system.
