description: Jack superpolynomials are eigenfunctions of the supersymmetric extension of the quantum trigonometric Calogero-Moser-Sutherland. They are orthogonal with respect to the scalar product, dubbed physical, that is naturally induced by this quantum-mechanical problem. But Jack superpolynomials can also be defined more combinatorially, starting from the multiplicative bases of symmetric superpolynomials, enforcing orthogonality with respect to a one-parameter deformation of the combinatorial scalar product. Both constructions turns out to be equivalent. This provides strong support for the correctness of the various underlying constructions and for the pivotal role of Jack superpolynomials in the theory of symmetric superpolynomials.

description: In some d-electron oxides the measured effective mass m(exptl) has long been known to be significantly larger than the model effective mass m(model) deduced from mean-field band theory, i.e., m(exptl) = beta * m(model), where beta > 1 is the "mass enhancement", or "mass renormalization" factor. Previous applications of density functional theory (DFT), based on the smallest number of possible magnetic, orbital, and structural degrees of freedom, missed such mass enhancement, a fact that was taken as evidence of strong electronic correlation being the exclusive enabling physics. The current paper reports that known modalities of energy-lowering symmetry-broken spin and structural effects included in mean-field DFT show mass enhancement for both electrons and holes in a range of d-electron perovskites SrVO3, SrTiO3, BaTiO3, and LaMnO3 as well as p-electron perovskites CsPbI3 and SrBiO3, including metals (SrVO3) and insulators (the rest). This is revealed only when enlarged unit cells of the same parent global symmetry, which are large enough to allow for symmetry breaking distortions and concomitant variations in spin order, are explored for their ability to lower the total energy. The paper analyzes the contributions of different symmetry-broken modalities to mass enhancement, finds common effects in the range of d- as well as p-electron perovskites. Thus, symmetry breaking in mean-field theory could describe effects that were previously attributed exclusively to complex correlated treatments. Indeed, broken symmetries are often experimentally observed, e.g., octahedral tilting, Jahn-Teller distortions, or bond disproportionation, and often provide intuitive explanations in terms of degeneracy removal due to lowering of structural symmetry, or as shifting of band energies in explainable directions.

description: A survey of commercial farmers throughout the United States showed 57 percent were members of marketing/farm supply cooperatives in 1980. An additional 14 percent used those cooperatives as nonmember patrons. Thirty-seven percent of commercial farmers were member-users of marketing cooperatives and 49 percent were member-users of farm supply cooperatives. The greatest proportion of commercial farmers holding cooperative membership was in the Northern Plains, among dairy farmers, and among those farmers with largest farm sales. The smallest proportion holding membership was in the South Central region and among those with smaller farm sales. Twenty-nine percent of all commercial farmers neither held membership in nor patronized any marketing/farm supply cooperative in 1980.

description: Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44 for the sample, and a NPV of US$21 million with a BCR of 75 for the region.

description: We clarify classical inflaton models by considering them as effective field theories `a la Ginzburg-Landau. In this approach, the WMAP statement excluding the pure phi^4 potential implies the presence of an inflaton mass term at the scale m ~ 10^{13}GeV.Chaotic, new and hybrid inflation models are studied in an unified manner.In all cases the inflaton potential takes the form V(phi)=m^2 M_{Pl}^2 v(phi/M_{Pl}), where all coefficients in v(varphi) are of order one.If such potential corresponds to supersymmetry breaking, the susy scale is sqrt{m M_{Pl}}~10^{16}GeV which coincides with the GUT scale. For red tilted spectrum new inflation turns to be favoured while for blue tilted spectrum, hybrid inflation turns to be the best choice.In both cases, we find an analytic formula relating the inflaton mass with r (tensor/scalar ratio) and the scalar spectral index ns: 10^6 m/M_{Pl} = 127 sqrt{r|1-n_s|} where the numerical coefficient follows from the WMAP amplitude. We review quantum phenomena during inflation which contribute to relevant observables in the CMB anisotropies and polarization and we focus on inflaton decay.The deviation from the scale invariant power spectrum is measured by a small parameter Delta.Delta regulates the infrared divergences too.In slow roll inflation, Delta is a simple function of the slow roll parameters. The quantum fluctuations can selfdecay in the inflationary expansion through processes forbidden in Minkowski. We compute the self-decay of the inflaton quantum fluctuations during slow roll:superhorizon fluctuations decay as eta^{Gamma} in conformal time where the new scaling dimension Gamma is expressed in terms of the amplitude, n_s and r. we discuss the implications for scalar and tensor perturbations as well as for non gaussianities.

description: We performed an intensive accretion disk reverberation mapping campaign on the high accretion rate active galactic nucleus Mrk 142 in early 2019. Mrk 142 was monitored with the Neil Gehrels Swift Observatory for 4 months in X-rays and 6 UV/optical filters. Ground-based photometric monitoring was obtained from the Las Cumbres Observatory, Liverpool Telescope and Dan Zowada Memorial Observatory in ugriz filters and the Yunnan Astronomical Observatory in V. Mrk 142 was highly variable throughout, displaying correlated variability across all wavelengths. We measure significant time lags between the different wavelength light curves, finding that through the UV and optical the wavelength-dependent lags, $τ(λ)$, generally follow the relation $τ(λ) \propto λ^{4/3}$, as expected for the $T\propto R^{-3/4}$ profile of a steady-state optically-thick, geometrically-thin accretion disk, though can also be fit by $τ(λ) \propto λ^{2}$, as expected for a slim disk. The exceptions are the u and U band, where an excess lag is observed, as has been observed in other AGN and attributed to continuum emission arising in the broad-line region. Furthermore, we perform a flux-flux analysis to separate the constant and variable components of the spectral energy distribution, finding that the flux-dependence of the variable component is consistent with the $f_ν\proptoν^{1/3}$ spectrum expected for a geometrically-thin accretion disk. Moreover, the X-ray to UV lag is significantly offset from an extrapolation of the UV/optical trend, with the X-rays showing a poorer correlation with the UV than the UV does with the optical. The magnitude of the UV/optical lags is consistent with a highly super-Eddington accretion rate.

Quality of service enhancements in IEEE 802.11 wireless LANs
Creators: name: Wong, George Wai
Publisher: name: University of British Columbia
Year: 2009

description: One of the most important of the many developments in telecommunications is the convergence of voice, video, and data communications within the Internet Protocol (IP) suite. IP was originally designed to support best-effort data services. The development of IP-based multimedia networking applications has imposed Quality of Service (QoS) requirements on the IP network, especially with respect to real-time traffic. The Internet Engineering Task Force (IETF) is currently working on QoS differentiation at the LP layer; however the result is sub-optimal without lower layers' support. With the increasing use of wireless Internet services over 802.11 wireless LANs, it is essential to focus on QoS differentiation support at the 802.11 MAC layer. To improve the current 802.11 MAC protocol, the IEEE Task Group E was formed and is defining QoS enhancements for the 802.11 MAC layer by introducing an Enhanced Distributed Coordination Function (EDCF). The EDCF provides prioritization enhancement of the 802.11 Distributed Coordination Function (DCF). The objective of this thesis is to propose and evaluate a novel packet retransmission algorithm called Age-Dependent Backoff to improve the QoS performance of EDCF. The ADB algorithm dynamically varies the persistent factor associated with the contention window, based on real-time packet queue age and lifetime. ADB maintains the backward compatibility property of EDCF and involves relatively easy implementation at low cost. Extensive simulation results obtained using OPNET software show that EDCF with the ADB retransmission algorithm provides low values for delay, jitter, and drop rate for realtime traffic without sacrificing the throughput of best-effort data traffic. ADB is a viable, novel and low cost means to improve the QoS performance of EDCF.

description: We present optical and X-ray identifications for the sixty-four radio sources in the GOODS-S ACS field revealed in the ATCA 1.4 GHz survey of the Chandra Deep Field South. Optical identifications are made using the ACS images and catalogs, while the X-ray view is provided by the Chandra X-ray Observatory 1 Ms observations. Redshifts for the identified sources are drawn from publicly available catalogs of spectroscopic observations and multi-band photometric-based estimates. Using this multiwavelength information we provide a first characterization of the faint radio source population in this region. The sample contains a mixture of star-forming galaxies and active galactic nuclei, as identified by their X-ray properties and optical spectroscopy. A large number of morphologically disturbed galaxies is found, possibly related to the star-formation phenomena. In spite of the very deep optical data available in this field, seven of the sixty-four radio sources have no optical identification to z(850)~28 mag. Only one of these is identified in the X-rays.

description: Exploring a backgated low density two-dimensional hole sample in the large $r_s$ regime we found a surprisingly rich phase diagram. At the highest densities, beside the $ν=1/3$, 2/3, and 2/5 fractional quantum Hall states, we observe both of the previously reported high field insulating and reentrant insulating phases. As the density is lowered, the reentrant insulating phase initially strengthens, then it unexpectedly starts weakening until it completely dissapears. At the lowest densities the terminal quantum Hall state moves from $ν=1/3$ to $ν=1$. The intricate behavior of the insulating phases can be explained by a non-monotonic melting line in the $ν$-$r_s$ phase space.

Nonlinear dynamics of inertial particles in the ocean: From drifters and floats to marine debris and Sargassum

description: Buoyant, finite-size or inertial particle motion is fundamentally unlike neutrally buoyant, infinitesimally small or Lagrangian particle motion. The de-jure fluid mechanics framework for the description of inertial particle dynamics is provided by the Maxey-Riley equation. Derived from first principles - a result of over a century of research since the pioneering work by Sir George Stokes - the Maxey-Riley equation is a Newton-type-law with several forces including (mainly) flow, added mass, shear-induced lift, and drag forces. In this paper we present an overview of recent efforts to port the Maxey-Riley framework to oceanography. These involved: 1) including the Coriolis force, which was found to explain behavior of submerged floats near mesoscale eddies; 2) accounting for the combined effects of ocean current and wind drag on inertial particles floating at the air-sea interface, which helped understand the formation of great garbage patches and the role of anticyclonic eddies as plastic debris traps; and 3) incorporating elastic forces, which are needed to simulate the drift of pelagic Sargassum. Insight on the nonlinear dynamics of inertial particles in every case was possible to be achieved by investigating long-time asymptotic behavior in the various Maxey-Riley equation forms, which represent singular perturbation problems involving slow and fast variables.

description: In the framework of time-dependent density functional theory, we obtain high-order harmonics of photon energies up to 10 Up from bilayer crystals with an interlayer spacing d = 70 Å. At grazing incidence, a clear double-plateau structure is observed in the harmonic spectrum. The photon energy of the second plateau far beyond atomic-like harmonics can be well explained by the inclusion of backscattering of ionized electrons. Ab initio simulations reveal that the cutoff of the second plateau is continuously extended with an increasing d. Our classical calculations predict that the maximum electronic kinetic energy is linearly dependent on d over a wide range. Moreover, the harmonic yield in the second plateau is significantly enhanced by increases in the wavelength of the driving laser. Owing to the confined spreading of the electronic wave packet, a beneficial wavelength scaling of λ2.85 is obtained. This study therefore establishes a novel and efficient way of producing high-energy light source based on layered nanostructures.

description: We present stellar age distributions of the Milky Way (MW) bulge region using ages for $\sim$6,000 high-luminosity ($\log(g) < 2.0$), metal-rich ($\rm [Fe/H] \ge -0.5$) bulge stars observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE). Ages are derived using {\it The Cannon} label-transfer method, trained on a sample of nearby luminous giants with precise parallaxes for which we obtain ages using a Bayesian isochrone-matching technique. We find that the metal-rich bulge is predominantly composed of old stars ($>$8 Gyr). We find evidence that the planar region of the bulge ($|Z_{\rm GC}| \le 0.25$ kpc) enriched in metallicity, $Z$, at a faster rate ($dZ/dt \sim$ 0.0034 ${\rm Gyr^{-1}}$) than regions farther from the plane ($dZ/dt \sim$ 0.0013 ${\rm Gyr^{-1}}$ at $|Z_{\rm GC}| > 1.00$ kpc). We identify a non-negligible fraction of younger stars (age $\sim$ 2--5 Gyr) at metallicities of $\rm +0.2 < [Fe/H] < +0.4$. These stars are preferentially found in the plane ($|Z_{\rm GC}| \le 0.25$ kpc) and between $R_{\rm cy} \approx 2-3$ kpc, with kinematics that are more consistent with rotation than are the kinematics of older stars at the same metallicities. We do not measure a significant age difference between stars found in and outside of the bar. These findings show that the bulge experienced an initial starburst that was more intense close to the plane than far from the plane. Then, star formation continued at super-solar metallicities in a thin disk at 2 kpc $\lesssim R_{\rm cy} \lesssim$ 3 kpc until $\sim$2 Gyr ago.

description: Trees are increasingly grown on-farm to supply wood and biomass needs within developing countries. Over the last several decades, within the irrigated rice-wheat growing lands of northern India, fast-growing poplar trees have been planted on tens of thousands of small farms. Recent debate regarding afforestation has raised the issue that water use is often increased when trees are planted. This ongoing debate focuses primarily on afforestation or reforestation of upland and rain-fed agricultural areas, and off-site impacts such as reduced streamflow. Adoption of poplar agroforestry in northern India, in contrast, is occurring in areas where land and water are already intensively used and managed for agricultural production. This study based on farmer survey data, used remote sensing and spatial hydrological modeling to investigate the importance and role of the poplar trees within the agricultural landscape, and to estimate their water use. Overall, results illustrate a potential for addressing the increasing global demand for wood products with trees grown on-farm within irrigated agroforestry systems.

description: We consider the (scalar) gradient fields $η=(η_b)$--with $b$ denoting the nearest-neighbor edges in $\Z^2$--that are distributed according to the Gibbs measure proportional to $\texte^{-βH(η)}ν(\textdη)$. Here $H=\sum_bV(η_b)$ is the Hamiltonian, $V$ is a symmetric potential, $β>0$ is the inverse temperature, and $ν$ is the Lebesgue measure on the linear space defined by imposing the loop condition $η_{b_1}+η_{b_2}=η_{b_3}+η_{b_4}$ for each plaquette $(b_1,b_2,b_3,b_4)$ in $\Z^2$. For convex $V$, Funaki and Spohn have shown that ergodic infinite-volume Gibbs measures are characterized by their tilt. We describe a mechanism by which the gradient Gibbs measures with non-convex $V$ undergo a structural, order-disorder phase transition at some intermediate value of inverse temperature $β$. At the transition point, there are at least two distinct gradient measures with zero tilt, i.e., $E η_b=0$.

description: The search for life on exoplanets is one of the grand scientific challenges of our time. The strategy to date has been to find (e.g., through transit surveys like Kepler) Earth-like exoplanets in their stars habitable zone, then use transmission spectroscopy to measure biosignature gases, especially oxygen, in the planets atmospheres (e.g., using JWST, the James Webb Space Telescope). Already there are more such planets than can be observed by JWST, and missions like the Transiting Exoplanet Survey Satellite and others will find more. A better understanding of the geochemical cycles relevant to biosignature gases is needed, to prioritize targets for costly follow-up observations and to help design future missions. We define a Detectability Index to quantify the likelihood that a biosignature gas could be assigned a biological vs. non-biological origin. We apply this index to the case of oxygen gas, O2, on Earth-like planets with varying water contents. We demonstrate that on Earth-like exoplanets with 0.2 weight percent (wt%) water (i.e., no exposed continents) a reduced flux of bioessential phosphorus limits the export of photosynthetically produced atmospheric O2 to levels indistinguishable from geophysical production by photolysis of water plus hydrogen escape. Higher water contents >1wt% that lead to high-pressure ice mantles further slow phosphorus cycling. Paradoxically, the maximum water content allowing use of O2 as a biosignature, 0.2wt%, is consistent with no water based on mass and radius. Thus, the utility of an O2 biosignature likely requires the direct detection of both water and land on a planet.

description: We apply the asymptotic iteration method (AIM) [J. Phys. A: Math. Gen. 36, 11807 (2003)] to solve new classes of second-order homogeneous linear differential equation. In particular, solutions are found for a general class of eigenvalue problems which includes Schroedinger problems with Coulomb, harmonic oscillator, or Poeschl-Teller potentials, as well as the special eigenproblems studied recently by Bender et al [J. Phys. A: Math. Gen. 34 9835 (2001)] and generalized in the present paper to higher dimensions.

description: Multiple species in the ecosystem are believed to compete cyclically for survival and thus maintain balance in nature. Stochasticity has also an inevitable role in this dynamics. Considering these attributes of nature, the stochastic dynamics of the rock-paper-scissor model based on the idea of cyclic dominance becomes an effective tool to capture different aspects of ecosystem. The evolutionary dynamics of this model crucially depends on different interactions representing different natural habits. In this framework we explore the role of mortality of individual organism in the collective survival of a species. For this purpose a new parameter called `natural death' is introduced. It is meant for bringing about the decease of an individual irrespective of any intra- and interspecific interaction. We perform Monte Carlo simulation followed by the stability analysis of different fixed points of defined rate equations and observe that the natural death rate is surprisingly one of the most significant factors in deciding whether an ecosystem would come up with a coexistence or a single species survival.

Some Mathematical Aspects of the Lifshitz Formula for the Thermal Casimir Force

description: The applicability of the Lifshitz formula is discussed to the case of two thick parallel plates made of real metal. The usual description of the zero-point vacuum oscillations on the background of the frequency-dependent dielectric permittivity is shown to be in contradiction with thermodynamics. Instead, the Lifshitz formula for the Casimir free energy should be reformulated in terms of the reflection coefficients containing the surface impedance instead of the dielectric permittivity. This approach is presently confirmed experimentally by precision measurements of the van der Waals and Casimir forces in micromechanical systems and it is in agreement with thermodynamics.

description: As urban development grows, the need for efficient concrete damage inspection has increased, driving interest in automated damage assessment. This research aims to optimise 3D damage acquisition and analysis for concrete structures. It focuses on three objectives: (1) developing cost-effective, high-precision 3D reconstruction methods by reducing errors caused by concrete's colour and shape; (2) improving reconstruction accuracy and flexibility through handheld, structured light-enhanced stereo vision; and (3) designing features that reduce computational demands while ensuring effective damage recognition. The objectives target enhanced accuracy, efficiency, and practicality for real-world damage assessment of concrete structures through ad-hoc optimisations.

Measuring precession in asymmetric compact binaries

description: Gravitational-wave observations of merging compact binaries hold the key to precision measurements of the objects' masses and spins. General-relativistic precession, caused by spins misaligned with the orbital angular momentum, is considered a crucial tracer for determining the binary's formation history and environment, and it also improves mass estimates -- its measurement is therefore of particular interest with wide-ranging implications. Precession leaves a characteristic signature in the emitted gravitational-wave signal that is even more pronounced in binaries with highly unequal masses. The recent observations of GW190412 and GW190814 have confirmed the existence of such asymmetric compact binaries. Here, we perform a systematic study to assess the confidence in measuring precession in gravitational-wave observations of high mass ratio binaries and, our ability to measure the mass of the lighter companion in neutron star -- black hole type systems. Using Bayesian model selection, we show that precession can be decisively identified for low-mass binaries with mass ratios as low as $1:3$ and mildly precessing spins with magnitudes $\lesssim 0.4$, even in the presence of systematic waveform errors.

Carbon Stars and other Luminous Stellar Populations in M33

description: The M33 galaxy is a nearby, relatively metal-poor, late-type spiral. Its proximity and almost face-on inclination means that it projects over a large area on the sky, making it an ideal candidate for wide-field CCD mosaic imaging. Photometry was obtained for more than 10^6 stars covering a 74' x 56' field centered on M33. Main sequence (MS), supergiant branch (SGB), red giant branch (RGB) and asymptotic giant branch (AGB) populations are identified and classified based on broad-band V and I photometry. Narrow-band filters are used to measure spectral features allowing the AGB population to be further divided into C and M-star types. The galactic structure of M33 is examined using star counts, colour-colour and colour-magnitude selected stellar populations. We use the C to M-star ratio to investigate the metallicity gradient in the disk of M33. The C/M-star ratio is found to increase and then flatten with increasing galactocentric radius in agreement with viscous disk formation models. The C-star luminosity function is found to be similar to M31 and the SMC, suggesting that C-stars should be useful distance indicators. The ``spectacular arcs of carbon stars'' in M33 postulated recently by Block et al. (2004) are found in our work to be simply an extension of M33's disk.

SoC interconnect architecture design and evaluation under timing constraints
Creators: name: Grecu, Cristian
Publisher: name: University of British Columbia
Year: 2009

description: System on chip design steadily evolves toward different non-overlapping abstraction levels. Very different competence and design tools will be needed at each level. One specific level of abstraction will deal with interconnect technologies, with a pronounced trend towards networks on chip. It is projected that, within five years, the large majority of end-user SoC products will consist of heterogeneous embedded processors, built on multi-processor SoC platforms (MP-SoC). There is a tremendous amount of research required to characterize the various topologies and their effectiveness for different application domains. A common issue with all network-on-chip topologies is communication latency. Due to the increase of global wire delay with technology scaling, pipelining is required to hide the latency associated with the exchange of data across the chip. The building blocks of a network-on-chip are intelligent switches, which provide a data transport mechanism across the chip. Their design is critical due to different architectural and circuit level trade-offs. This work is novel in that it addresses the issues of quantifying the delay of different pipeline stages in an on-chip topology, and evaluates the effectiveness of a given topology in forthcoming technology nodes.

description: With a sample of about 227 million BB pairs recorded with the BABAR detector at the PEP-II storage ring we perform a full angular analysis of the decay B0->PhiK*0(892). We measure the branching fraction to be (9.2+-0.9+-0.5)10^-6 and determine the fractions of longitudinal and parity-odd transverse contributions as f_L=0.52+-0.05+-0.02 and f_perp=0.22+-0.05+-0.02, respectively. The phases of the parity-even and parity-odd transverse amplitudes relative to the longitudinal amplitude are found to be phi_parallel= 2.34+0.23-0.20+-0.05 rad and phi_perp=2.47+-0.25+-0.05 rad, respectively. We measure five CP asymmetries which provide important limits on CP violation originating from new physics. We also observe the decay B0->PhiK*0(1430).

description: This document is meant to present a framework for analyzing the institutions related to water management in a river basin context. The design of the five-country regional study undertaken by IWMI on “Development of Effective Water Management Institutions” provided a new methodology and a framework for river basin studies. It consists of four key components of diagnostic investigations related to water resources management in a river basin, which are interrelated. These key components are the physical system, water accounting, socioeconomic situation and performance. This study design is given in the Study’s Inception Report of 15 June 1999, and the Methodological Guidelines of 1 October 1999. This document takes one step further, and provides a conceptual framework for analyzing the institutional framework for water resources management in a river basin. The major thrust of this framework for institutional analysis is that the four key areas of diagnostic studies in a river basin are shown to be closely linked to the institutional frame work for integrated water resources management in the context of a river basin.
