description: The low-mode averaging technique is a powerful tool for reducing large fluctuations in correlation functions due to low-mode eigenvalues of the Dirac operator. In this work we propose a generalization to baryons and test our method on two-point correlation functions of left-handed nucleons, computed with quenched Neuberger fermions on a lattice with extension L=1.5 fm. We show that the statistical fluctuations can be reduced and the baryon signal significantly improved.

description: The Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) program monitors 849 active galactic nuclei (AGN) both spectroscopically and photometrically. The photometric observations used in this work span over four years and provide an excellent baseline for variability studies of these objects. We present the photometric light curves from 2014 to 2017 obtained by the Steward Observatory's Bok telescope and the CFHT telescope with MegaCam. We provide details on the data acquisition and processing of the data from each telescope, the difference imaging photometry used to produce the light curves, and the calculation of a variability index to quantify each AGN's variability. We find that the Welch-Stetson J-index provides a useful characterization of AGN variability and can be used to select AGNs for further study.

description: We investigate the three-dimensional motion of a test particle in the gravitational field generated by a non-spherical compact object endowed with a mass quadrupole moment, described by the Erez-Rosen metric, and a radiation field, including the general relativistic Poynting-Robertson effect, coming from a rigidly rotating spherical emitting source located outside of the compact object. We derive the equations of motion for test particles influenced by such radiation field, recovering the two-dimensional description, and the weak-field approximation. This dynamical system admits the existence of a critical hypersurface, region where gravitational and radiation forces balance. Selected test particle orbits for different set of input parameters are displayed. The possible configurations on the critical hypersurfaces can be either latitudinal drift towards the equatorial ring or suspended orbits. We discuss about the existence of multiple hypersurface solutions through a simple method to perform the calculations. We graphically prove also that the critical hypersurfaces are stable configurations within the Lyapunov theory.

description: On December 23, 2003, Bovine Spongiform Encephalopathy (BSE), widely known as 'mad cow disease,' was found in the state of Washington. Major beef importing countries, including Japan, South Korea, and Mexico, banned imports of beef and beef products produced in the United States. A single case of BSE occurred on May 20, 2003, in Canada, prompting the United States to close its border to Canadian beef products. Prior to these BSE outbreaks in North America, the disease was detected in the United Kingdom and Japan. U.S. consumer response to the BSE outbreak in Washington is unknown. However, the previous cases which occurred in the United Kingdom and Japan indicate that the BSE outbreaks reduced domestic consumption of beef produced in the countries and increased beef imports from BSE-free countries, suggesting that consumers in the United States may respond negatively to the BSE outbreak and reduce their consumption of beef. Based on consumer response to BSE outbreaks in the United Kingdom and Japan, the BSE outbreak in Washington could reduce domestic consumption by 10% and exports by 75%, which could decrease the price of beef about 15%, from 370cents/lb in the third quarter of 2003 to 313.7cents/lb. However, prices of pork and chicken would increase about 3%, as consumers in this country switch from beef to pork and chicken consumption. The decreased consumption and export of beef will affect prices of slaughter and feeder cattle accordingly. The price of slaughter cattle would decrease about 13.5%, and the price of feeder cattle would decrease about 16% in the United States. If there are additional BSE outbreaks in the United States, the impacts will be much more significant. Domestic consumption of beef could decrease more than 20%, and U.S. exports would shutdown completely. In this case, the domestic price of beef could decrease 26%. Prices of slaughter and feeder cattle would decrease accordingly, about 20.9% and 24.5%, respectively, which could destroy the U.S. beef and cattle industry. To isolate a future BSE outbreak in the region, it is important to improve traceability of the infected animals by introducing both country of origin and regional labeling and preserve it through the supply chain. If the labeling system is developed for the United States, and if U.S. processors could segregate cattle based on its origin by labeling, the impacts of BSE outbreaks on the U.S. beef/cattle industry could be less prominent. Labeling would allow U.S. and foreign consumers to distinguish beef coming from BSE-free regions in the United States.

description: We present low resolution multi-object spectroscopy of an I-band magnitude limited (I_{AB} ~ 23--23.5) sample of galaxies located in an area centered on the Hubble Deep Field-South (HDFS). The observations were obtained using the Focal Reducer low dispersion Spectrograph (FORS) on the ESO Very Large Telescope. Thirty-two primary spectroscopic targets in the HST-WFPC2 HDFS were supplemented with galaxies detected in the Infrared Space Observatory's survey of the HDFS and the ESO Imaging Deep Survey to comprise a sample of 100 galaxies for spectroscopic observations. Based on detections of several emission lines, such as [OII]3727, H_beta and [OIII]5007, or other spectroscopic features, we have measured accurate redshifts for 50 objects in the central HDFS and flanking fields. The redshift range of the current sample of galaxies is 0.6--1.2, with a median redshift of 1.13 (at I ~ 23.5 not corrected for completeness). The sample is dominated by starburst galaxies with only a small fraction of ellipticals (~10%). For the emission line objects, the extinction corrected [OII]3727 line strengths yield estimates of star formation rates in the range 0.5--30 M_solar/yr. We have used the present data to derive the [OII]3727 luminosity function up to redshift of 1.2. When combined with [OII]3727 luminosity densities for the local and high redshift Universe, our results confirm the steep rise in the star formation rate (SFR) to z ~ 1.3.

description: The general objective of this study is to analyze the economic impact of the recently negotiated U.S. - Australia Free Trade Agreement (FTA). Specific objectives are to estimate changes in trade and prices in different sectors of the U.S. and Australian economies and to determine the impact on U.S. agriculture and the U.S. beef industry in particular. The results of a general equilibrium analysis suggest that the FTA will not have significant effects on the economies of Australia, the United States, or the rest of the world. The United States could achieve gains in the manufacturing sector, but the U.S. agricultural sector could experience small losses as Australia could increase exports of dairy products and beef to the United States. The results of an econometric model, however, indicate that the quota increases under the 18-year phase-in period of the agreement would have a minimal impact on the U.S. beef industry. Benefits for U.S. agriculture appear to be small. Australia is not an important market for U.S. agriculture. U.S. soybean meal exports could increase, as could horticultural exports, but the bigger effect would likely be on exports of manufacturing products.

description: We investigate the analogue of the Randall-Sundrum brane-world in the case when the bulk contains a black hole. Instead of the static vacuum Minkowski brane of the RS model, we have an Einstein static vacuum brane. We find that the presence of the bulk black hole has a dramatic effect on the gravity that is felt by brane observers. In the RS model, the 5D graviton has a stable localized zero-mode that reproduces 4D gravity on the brane at low energies. With a bulk black hole, there is no such solution -- gravity is delocalized by the 5D horizon. However, the brane does support a discrete spectrum of metastable massive bound states, or quasinormal modes, as was recently shown to be the case in the RS scenario. These states should dominate the high frequency component of the bulk gravity wave spectrum on a cosmological brane. We expect our results to generalize to any bulk spacetime containing a Killing horizon.

description: The nuclear ground state properties of 67 80As nuclei have been investigated within the framework of relativistic mean field (RMF) approach. The RMF model with density dependent (DDME2) interaction is utilized for the calculation of potential energy curves and the nuclear ground state deformation parameters $β_2$ of selected As isotopes. Later, the $β$ decay properties of As isotopes were studied using the proton neutron quasi particle random phase approximation pnQRPA model. These include Gamow Tellar (GT) strength distributions, log ft values, $β$ decay half lives, stellar $β$ plus minus decays and stellar electron positron capture rates. The $β_2$ values computed from RMF model were employed in the on QRPA model as an input parameter for the calculations of $β$-decay properties for 67 80As. The calculated log ft values were in decent agreement with the measured data. The predicted $β$-decay half lives matched the experimental values within a factor of 10. The stellar rates were compared with the shell model results. Only at high temperature and density values, the sum of $β$ plus and electron capture rates had a finite contribution. On the other hand, the sum of $β$ negative and positron capture rates were sizeable only at low density and high temperature values. For all such cases, the pn QRPA rates were found to be bigger than the shell model rates up to a factor of 33 or more. The findings reported in the current investigation could prove valuable for simulating the late stage stellar evolution of massive stars.

description: Fluid milk and cheese imports have been increasing in Mexico, especially in the years preceding the devaluation of the peso. This study estimates import demand for fluid milk and cheese in Mexico and for 1975-1995. Estimated real exchange rate and income parameters are then used to forecast import demand for the two dairy products through the year 2000. Results show that fluid milk imports will continue to increase after the drop in 1995, and will reach its 1994 levels by 2000. Cheese imports however, will decline to about 10,000 MT and will stabilize at that level.

description: The Wisconsin Economic Impact Modeling System, a conjoined input-output/econometric model of Wisconsin counties, is used to simulate the economic and fiscal impact of two alternative residential development patterns. Under the first scenario, the impact of migrating retirees on a small tri-county region in northern Wisconsin is examined. Under the second scenario, the impact of the migration of younger families with children is examined. A comparison-contrast between the two scenarios demonstrates that the characteristics of the migrating household can have a significant impact on the nature of the impacts.
Suppression of inelastic collisions of polar $^1 Σ$ state molecules in an electrostatic field

description: Collisions of polar $^{1}Σ$ state molecules at ultralow energies are considered, within a model that accounts for long-range dipole-dipole interactions, plus rotation of the molecules. We predict a substantial suppression of dipole-driven inelastic collisions at high values of the applied electric field, namely, field values of several times $B_e/μ$. Here $B_e$ is the rotational constant, and $μ$ is the electric dipole moment of molecules. The sudden large drop in the inelastic cross section is attributed to the onset of degeneracy between molecular rotational levels, which dramatically alters the scattering Hamiltonian. As a result of the large ratio of elastic to inelastic collision rates, we predict that evaporative cooling may be feasible for $^{1}Σ$ state molecules in weak-field-seeking states, provided a large bias electric field is present.
A built-in RMS-to-DC converter for power supply monitoring of analog/mixed-signal circuits
Creators: name: Luo, Yong
Publisher: name: University of British Columbia
Year: 2009

description: Recently, the interest in analog and mixed-signal IC test has been raised dramatically. The development of high speed and high performance analog/mixed-signal circuits embedded in a single chip with their digital peer keeps posing new challenges to VLSI test engineers. Built-in self-test (BIST) schemes have been recognized as capable of bringing improvements to analog and mixed-signal circuits testing. The power supply current monitoring as a structural testing methodology, which is applicable to both digital and analog/mixed-signal circuits testing, has recently been attracting more attention from both academia and industry. In this thesis, the power supply monitoring of analog and mixed-signal circuits testing is reviewed. A BIST scheme is presented for power supply rms current testing. A new built-in rms-to-dc converter is proposed. The RMS-to-DC computation is carried out in the current domain. The system generates a digital signature proportional to the RMS value of the supply current. The digital signature is critical for an effective on-chip decision. A new MOS current squarer/divider circuit required in the converter is also proposed and implemented in a standard 0.18 μm CMOS technology. Silicon measurement results illustrate that the total harmonic distortion is less than 1.1%. The RMS-to-DC converter has been implemented in the standard 0.35 μm CMOS technology. The total on-chip capacitance is only 74 pF. The effectiveness of the RMS-to-DC converter has been verified by simulation. The simulated relative error of the RMS-to-DC converter is less than 1% with a 100 KHz sinusoidal input signal. This circuit is suitable for BIST applications on analog and mixed-signal ICs.

End-to-end-acknowledged indirect TCP for wireless internetworked environments
Creators: name: Chim, Victor
Publisher: name: University of British Columbia
Year: 2009

description: TCP is a transport protocol developed for reliable end-to-end communications over the Internet, and is used by many popular Internet applications, including electronic mail, Telnet, FTP and WWW. TCP is designed to perform well over fixed internetworked environments, where packet losses occur primarily due to network congestion. It attempts to alleviate the congestion problem by initiating its congestion control mechanisms when a packet is believed to have lost. Perceived demand for mobile computing means that wireless links and mobile hosts will likely represent a large part of the next generation Internet. Wireless transmission errors and host mobility can introduce significant packet losses in wireless networks. TCP performance degrades on such wireless internetworked environments because the same congestion control mechanisms are invoked in response to these non-congestion related losses. In this thesis, an alternative transport protocol, known as end-to-end-acknowledged indirect TCP (EI-TCP), is proposed for the wireless internetworked environment. It is based on the indirect TCP (I-TCP) concept, but end-to-end semantics of TCP acknowledgments are maintained. Using computer simulations on a wireless internetworking model, throughput performance of EI-TCP is evaluated and compared against I-TCP and end-to-end TCP for bulk data transfer. Results indicate that by more effective error recovery over the wireless link, EITCP and I-TCP perform significantly better than end-to-end TCP. Also, EI-TCP performs slightly better than I-TCP with a more steady data flow as a result of end-to-end flow control. With link layer retransmissions over the wireless link, EI-TCP and I-TCP can boost end-toend throughput by avoiding competing retransmissions between transport and link layers.

The Drag Instability in a 1D Isothermal C-Shock

description: We investigate whether the drag instability, proposed by Gu et al., occurs in a one-dimensional (1D) C-shock. The 1D background model proposed by Chen and Ostriker for a steady isothermal C-shock is adopted, and a 1D isothermal linear analysis is performed. We confirm the postulation of Gu et al. that the drift velocity between the ions and the neutrals is sufficiently high within a C-shock to allow for the drag instability. We also study the underlying physics of the decaying modes in the shock and post-shock regions. The drag instability is an overstability phenomenon associated with an exponentially growing mode of a propagating wave. We find that the growing wave mode can only propagate downstream within the shock and subsequently decay in the post-shock region. The maximum total growth (MTG) for such an unstable wave before it is damped is estimated in typical environments of star-forming clouds, which is approximately 10-30 times larger than the initial perturbation at the modest shock velocities and can be significantly enhanced several hundred times for a stronger C-shock with a larger width.

description: The mass growth of protostars is a central element to the determination of fundamental stellar population properties such as the initial mass function. Constraining the accretion history of individual protostars is therefore an important aspect of star formation research. The goal of the study presented here is to determine whether high-mass (proto)stars gain their mass from a compact (<0.1pc) fixed-mass reservoir of gas, often referred to as dense cores, in which they are embedded, or whether the mass growth of high-mass stars is governed by the dynamical evolution of the parsec-scale clump that typically surrounds them. To achieve this goal, we performed a 350micron continuum mapping of 11 infrared dark clouds, along side some of their neighbouring clumps, with the ArTéMiS camera on APEX. By identifying about 200 compact ArTéMiS sources, and matching them with Herschel Hi-GAL 70micron sources, we have been able to produce mass vs. temperature diagrams. We compare the nature (i.e. starless or protostellar) and location of the ArTéMiS sources in these diagrams with modelled evolutionary tracks of both core-fed and clump-fed accretion scenarios. We argue that the latter provide a better agreement with the observed distribution of high-mass star-forming cores. However, a robust and definitive conclusion on the question of the accretion history of high-mass stars requires larger number statistics.

description: In this paper, we analyze the performance and energy consumption of an Arm-based high-performance computing (HPC) system developed within the European project Mont-Blanc 3. This system, called Dibona, has been integrated by ATOS/Bull, and it is powered by the latest Marvell's CPU, ThunderX2. This CPU is the same one that powers the Astra supercomputer, the first Arm-based supercomputer entering the Top500 in November 2018. We study from micro-benchmarks up to large production codes. We include an interdisciplinary evaluation of three scientific applications (a finite-element fluid dynamics code, a smoothed particle hydrodynamics code, and a lattice Boltzmann code) and the Graph 500 benchmark, focusing on parallel and energy efficiency as well as studying their scalability up to thousands of Armv8 cores. For comparison, we run the same tests on state-of-the-art x86 nodes included in Dibona and the Tier-0 supercomputer MareNostrum4. Our experiments show that the ThunderX2 has a 25% lower performance on average, mainly due to its small vector unit yet somewhat compensated by its 30% wider links between the CPU and the main memory. We found that the software ecosystem of the Armv8 architecture is comparable to the one available for Intel. Our results also show that ThunderX2 delivers similar or better energy-to-solution and scalability, proving that Arm-based chips are legitimate contenders in the market of next-generation HPC systems.

description: We discuss the physical properties of four quasar jets imaged with the Chandra X-ray Observatory in the course of a survey for X-ray emission from radio jets. These objects have sufficient counts to study their spatially resolved properties, even in the 5 ks survey observations. We have acquired Australia Telescope Compact Array data with resolution matching Chandra. We have searched for optical emission with Magellan, with sub-arcsecond resolution. The radio to X-ray spectral energy distribution for most of the individual regions indicates against synchrotron radiation from a single-component electron spectrum. We therefore explore the consequences of assuming that the X-ray emission is the result of inverse Compton scattering on the cosmic microwave background. If particles and magnetic fields are near minimum energy density in the jet rest frames, then the emitting regions must be relativistically beamed, even at distances of order 500 kpc from the quasar. We estimate the magnetic field strengths, relativistic Doppler factors, and kinetic energy flux as a function of distance from the quasar core for two or three distinct regions along each jet. We develop, for the first time, estimates in the uncertainties in these parameters, recognizing that they are dominated by our assumptions in applying the standard synchrotron minimum energy conditions. The kinetic power is comparable with, or exceeds, the quasar radiative luminosity, implying that the jets are a significant factor in the energetics of the accretion process powering the central black hole. The measured radiative efficiencies of the jets are of order 10^(-4).

description: Additional file 1: Table S1. Elemental analysis of PEI-SWNTs and source materials used in this study. Mass percentage of each element is reported. Degree of functionalization (DFG) refers to the fraction of carbons on the surface lattice that contain a branched PEI 25 k functional group, calculated as described in the methods section. This DFG represents a 12.54 PEI to SWNT ratio by mass (i.e., 50 ng of PEI-SWNTs contain 627 ng of PEI). Figure S1. Validation of RNA-seq data by RT-qPCR. (A) Normalized log2(RPKM) values for selected genes from Clusters 1 and 2 (PEI-SWNT specific genes) and Clusters 4 and 6 (SWNT specific genes) from RNA-seq data. (B) mRNA levels of same genes as in (A) measured by RT-qPCR. The lower and upper hinges of the boxplot correspond to the first and third quartiles, the upper and lower whiskers correspond to the largest value no further than 1.5 times the inter-quartile range. Statistical significance was determined by a one-way ANOVA with post-hoc Tukey HSD test. Letters denote significant differences among means (n = 5 in A and n = 3 in B). Figure S2.

description: The behavior of the ensemble of coupled van der Pol oscillators is abundant when coupling parameters are changed. Incoherent and chimera-like regimes are observed at small values of the coupling strength parameter. Synchronization takes place with an increase in the coupling strength and coupling range parameters. Various chimera and solitary states are realised when the coupling strength parameter is sufficiently large. The single van der Pol oscillator is taken in the regime of relaxation oscillations. Therefore, the lattice may realise spiral wave and spiral wave chimera regimes. Besides, target wave and solitary state regimes are observed in the ensemble. Finally, the solitary state and solitary state chimera regimes are firstly shown for the lattice of coupled van der Pol oscillators.

description: AC magnetoimpedance measurements performed on proximity-effect coupled Josephson junction arrays on a dice lattice reveal unconventional behaviour resulting from the interplay between the frustration f created by the applied magnetic field and the particular geometry of the system. While the inverse magnetoinductance exhibits prominent peaks at f=1/3 and at f=1/6 (and weaker structures at f=1/9,2/9,1/12,...) reflecting vortex states with a high degree of superconducting phase coherence, the deep minimum at f=1/2 points to a state in which the phase coherence is strongly suppressed. These observations are discussed at the light of recent theoretical work in which the concept of accidental degeneracy plays a central role.

description: Recently, neural implicit 3D reconstruction in indoor scenarios has become popular due to its simplicity and impressive performance. Previous works could produce complete results leveraging monocular priors of normal or depth. However, they may suffer from over-smoothed reconstructions and long-time optimization due to unbiased sampling and inaccurate monocular priors. In this paper, we propose a novel neural implicit surface reconstruction method, named FD-NeuS, to learn fine-detailed 3D models using multi-level importance sampling strategy and multi-view consistency methodology. Specifically, we leverage segmentation priors to guide region-based ray sampling, and use piecewise exponential functions as weights to pilot 3D points sampling along the rays, ensuring more attention on important regions. In addition, we introduce multi-view feature consistency and multi-view normal consistency as supervision and uncertainty respectively, which further improve the reconstruction of details. Extensive quantitative and qualitative results show that FD-NeuS outperforms existing methods in various scenes.
