description: Characterized by the absence of inversion symmetry, non-centrosymmetric materials are of great interest because they exhibit ferroelectricity, second harmonic generation, emergent Weyl fermions, and other fascinating phenomena. It is expected that if time-reversal symmetry is also broken, additional magneto-electric effects can emerge from the interplay between magnetism and electronic order. Here we report topological conducting properties in the non-centrosymmetric magnet PrAlGe. By photoemission spectroscopy, we observe an arc parametrizing surface-localized states---a topological arc. Using the bulk-boundary correspondence, we conclude that these arcs correspond to projected topological charges of $\pm{1}$ in the surface Brillouin zone, demonstrating the presence of magnetic Weyl quasiparticles in bulk. We further observe a large anomalous Hall response, arising from diverging bulk Berry curvature fields associated with the magnetic Weyl band structure. Our results demonstrate a topological phase with robust electronic surface states and anomalous transport in a non-centrosymmetric magnet for the first time, providing a novel material platform to study the interplay between magnetic order, band topology and transport.

description: Aiming to establish a rigorous link between macroscopic random motion (described e.g. by Langevin-type theories) and microscopic dynamics, we have undertaken a kinetic-theoretical study of the dynamics of a classical test-particle weakly coupled to a large heat-bath in thermal equilibrium. Both subsystems are subject to an external force field. From the (time-non-local) generalized master equation a Fokker-Planck-type equation follows as a "quasi-Markovian" approximation. The kinetic operator thus defined is shown to be ill-defined; in specific, it does not preserve the positivity of the test-particle distribution function $f(\mathbf{x}, \mathbf{v}; t)$. Adopting an alternative approach, previously proposed for quantum open systems, is proposed to lead to a correct kinetic operator, which yields all the expected properties. A set of explicit expressions for the diffusion and drift coefficients are obtained, allowing for modelling macroscopic diffusion and dynamical friction phenomena, in terms of an external field and intrinsic physical parameters.

We show that its objects can be viewed as sheaves on the associated moment graph. We introduce an exact structure and show that Soergel's "special" bimodules are the projective objects. Then we construct the indecomposable projectives by both a global and a local method, discuss a version of the Kazhdan-Lusztig conjecture and prove it for universal Coxeter systems.

description: As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. The National Agricultural Statistics Service (NASS) collaborated with USDA:APHIS:VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. Data for Part V: Quality Assurance Profile were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 1 and January 31, 1994. The average weaning weight of calves weaned in 1993 was 504 pounds; the average value was $467.34. For breeding-age females, the average weight was 1024 pounds; the average value was $577.86. For breeding-age bulls, the average weight was 1430 pounds; the average value was $1137.06. Thirty-three percent of breeding-age females were sold due to pregnancy status; twenty-one percent were sold due to age or bad teeth. Forty-five percent of calves weaned between July 1 and December 31 were sold during 1993. Thirty-three percent of calves were kept to graze or feed. Seven percent of calves under 3 weeks old were affected by scours. Seven percent of the 1993 calf crop died or was lost. The largest number of calves were lost to calving problems, followed by weather (32 and 22 percent, respectively). The health conditions that the greatest number of producers agreed had a significant economic impact on cow/calf operations included external and internal parasites (21 and 19 percent of producers, respectively).

description: Radio emission from meteors or meteor radio afterglows (MRAs) were first detected using the all-sky imaging capabilities of the first station of the Long Wavelength Array (LWA1). In this work, we use the recently commissioned LWA Sevilleta (LWA-SV) station along with the LWA1 to carry out co-ordinated observations. The combined all-sky observations with LWA1 and LWA-SV have co-observed 32 MRAs and 21 transmitter reflections from meteors (meteor scatter events) which are believed to be specular reflections from overdense trails. The flux density of the events observed by each station were measured from the all-sky images. Triangulating the angular direction of events from each station gave the physical location and the distance of the event to each station. The luminosity of the events in each station were calculated using the flux distance relation for an isotropic source. The luminosity distribution for MRAs and meteor scatter events observed by each station shows a clear distinction between these two types of events as the ratio of luminosities are closer to unity for MRAs than the meteor scatter events. Furthermore, we find that MRAs follow an isotropic radiation pattern. This suggests, either a complete incoherent emission mechanism or an incoherent addition of coherently emitting small regions within the meteor trail.

description: In recent years, we have witnessed the rise of deep learning. Deep neural networks have proved their success in many areas. However, the optimization of these networks has become more difficult as neural networks going deeper and datasets becoming bigger. Therefore, more advanced optimization algorithms have been proposed over the past years. In this study, widely used optimization algorithms for deep learning are examined in detail. To this end, these algorithms called adaptive gradient methods are implemented for both supervised and unsupervised tasks. The behaviour of the algorithms during training and results on four image datasets, namely, MNIST, CIFAR-10, Kaggle Flowers and Labeled Faces in the Wild are compared by pointing out their differences against basic optimization algorithms.

description: This report is the second of a three-part release of national information from the second National Animal Health Monitoring System (NAHMS) swine study, the Swine '95 Grower/Finisher. The 1990 National Swine Survey focused on farrowing sows and preweaning piglets. For the Swine '95 Study, the USDA's National Agricultural Statistics Service (NASS) collaborated with Veterinary Services (VS) to select a producer sample that was statistically designed to provide inferences to the nation's swine population. Data collected for the study represented the top 16 pork states and nearly 91 percent of the U.S. hog inventory, as well as nearly three fourths of the nation's pork producers. Data for this report were collected from 418 producers whose operations had 300 or more market hogs, including at least one of 120 or more pounds. The most frequent reason for switching pigs in the grower/finisher phase from one type of diet to the next was weight; number of diets fed was likely to increase as the size of an operation increased. Percent operations feeding different diets to males and females also increased as the size of an operation increased. Over 92 percent of grower/finisher pigs received preventive/growth promotant antibiotics in feed. Agents most frequently used were bacitracin (52 percent of operations) and chlortetracycline (41 percent of operations). The most frequent source of grower/finisher pigs was on-site farrowing and nursery units (77 percent of operations). The most frequently diagnosed disease in breeding herds was porcine reproductive and respiratory syndrome (PRRS, 17 percent of operations). The most frequently diagnosed disease in nursery pigs was Escherichia coli (21 percent of operations). Thirty-eight percent of grower/finisher deaths were due to respiratory problems. The per-pig average feed efficiency was 3.24 lbs fed/lb gained. Sixty-five percent of operations marketed pigs directly to a slaughter plant buying station. Contact for this paper: Eric Bush

description: In the standard Minority Game, players use historical minority choices as the sole public information to pick one out of the two alternatives. However, publishing historical minority choices is not the only way to present global system information to players when more than two alternatives are available. Thus, it is instructive to study the dynamics and cooperative behaviors of this extended game as a function of the global information provided. We numerically find that although the system dynamics depends on the kind of public information given to the players, the degree of cooperation follows the same trend as that of the standard Minority Game. We also explain most of our findings by the crowd-anticrowd theory.

For the Swine '95 study, the USDA's National Agricultural Statistics Service (NASS) collaborated with Veterinary Services (VS) to select a producer sample that was statistically designed to provide inferences to the nation's swine population. Data collected for the study represented the top 16 pork states and nearly 91 percent of the U.S. hog inventory, as well as nearly three fourths of the nation's pork producers. In the 6 years from 1990 through 1995, hog and pig inventory estimates increased approximately 7 percent. The number of U.S. swine operations decreased more than 30 percent. The proportion of herds with an inventory of 1000 head or more consistently increased. Preweaning deaths per litter decreased 20 percent (from 1.10 to 0.88) from 1990 to 1995. A significant decrease in the number of scours-related deaths was reported along with a slight increase in unknown problems causing preweaning deaths. Being laid on continued to be the leading cause of preweaning deaths. Scours was identified as the leading cause of nursery pig deaths in 1990 (25 percent), while respiratory problems accounted for the highest mortality in 1995 (32 percent). An increase in scours-related mortality of grower/finishers was identified by producers in the Swine '95 Study over the 1990 study (from 1.9 percent to 7.1 percent). Administration of antibiotics as a preventive practice for sows, gilts, and boars increased dramatically. From 1973 to 1992, there was a sharp drop in the total number of foodborne disease outbreaks attributed to pork or ham. World pork production increased 8 percent between 1991 and 1996.

description: Two-port demodulation reference signals (DMRS) have been employed in new radio (NR) recently. In this paper, we firstly propose a minimum mean square error (MMSE) scheme with full priori knowledge (F-MMSE) to achieve the channel estimation of two-port DMRS in NR. When the two ports are assigned to different users, the full priori knowledge of two ports is not easy to be obtained for one user. Then, we present a MMSE scheme with partial priori knowledge (P-MMSE). Finally, numerical results show that the proposed schemes achieve satisfactory channel estimation performance. Moreover, for both mean square error and bit error ratio metrics, the proposed schemes can achieve better performance compared with the classical discrete Fourier transform based channel estimation. Particularly, P-MMSE scheme delivers almost the same performance compared with F-MMSE scheme by a small amount of prior knowledge.

Denitrification in a landfill bioreactor with the use of methane as a source of carbon and/or electron donor for denitrification
Creators: name: Aljarallah, Rawa
Publisher: name: University of British Columbia
Year: 2009

description: Recycled landfill leachate is often characterized by its high ammonia content, which can be nitrified in an aerobic bioreactor. This research investigates the capability of landfill bioreactors to remove nitrate by denitrification with a focus on utilizing the methane flow as a carbon source. Eight lysimeters that contained synthetic municipal solid waste were operated for 510 days to demonstrate the feasibility of converting nitrate, at concentrations between 20 and 2000 mg/L, to nitrogen gas. The results show that the landfill as a bioreactor is capable of denitrifying this wide range of nitrate concentrations with an efficiency up to 100%. At low nitrate concentrations (20- 100 mg-N/L), denitrification was feasible with high efficiency in young and mature landfills, without affecting landfill activities (i.e. extent of waste degradation). However, denitrification with high nitrate concentrations (800-2000 mg-N/L) was associated with less gas production and hence less waste degradation. As the nitrate concentration increases, this effect also increases. In addition, at high nitrate concentrations, the denitrification efficiency decreases as the landfill ages due to carbon deficiency. The results also suggest that the carbon deficiency causes incomplete denitrification. The use of methane as a carbon source for denitrification was not detected during the early stages of the landfill life. In mature landfills, methane gas enhanced denitrification efficiency, even at high nitrate concentrations (1500 mg-N/L). Finally, testing was conducted to evaluate the kinetics of denitrification supported by methane or leachate. Results show that denitrifiers can grow on leachate, and consume nitrate at a rate faster than when growing on methanol. Denitrifiers were able to grow on methane, but at a much slower rate.

description: Constraint satisfaction problems (CSPs) are an important formal framework for the uniform treatment of various prominent AI tasks, e.g., coloring or scheduling problems. Solving CSPs is, in general, known to be NP-complete and fixed-parameter intractable when parameterized by their constraint scopes. We give a characterization of those classes of CSPs for which the problem becomes fixed-parameter tractable. Our characterization significantly increases the utility of the CSP framework by making it possible to decide the fixed-parameter tractability of problems via their CSP formulations. We further extend our characterization to the evaluation of unions of conjunctive queries, a fundamental problem in databases. Furthermore, we provide some new insight on the frontier of PTIME solvability of CSPs. In particular, we observe that bounded fractional hypertree width is more general than bounded hypertree width only for classes that exhibit a certain type of exponential growth. The presented work resolves a long-standing open problem and yields powerful new tools for complexity research in AI and database theory.

description: We report phase-referencing VLBA observations of H2O masers near the star-forming region W3(OH) to measure their parallax and absolute proper motions. The measured annual parallax is 0.489 +/- 0.017 milli-arcseconds (2.04 +/- 0.07 kpc), where the error is dominated by a systematic atmospheric contribution. This distance is consistent with photometric distances from previous observations and with the distance determined from CH3OH maser astrometry presented in a related paper. We also find that the source driving the H2O outflow, the ``TW-object'', moves with a 3-dimensional velocity of > 7 km/s relative to the ultracompact HII region W3(OH).

description: We present two experiments that provide information on spin anisotropy and the magnetic structure of NaxCoO2. First, we report low-energy neutron inelastic scattering measurements of the zone-center magnetic excitations in the magnetically ordered phase of Na0.75CoO2. The energy spectra suggest the existence of two gaps, and are very well fitted by a spin-wave model with both in-plane and out-of-plane anisotropy terms. The gap energies decrease with increasing temperature and both gaps are found to have closed when the temperature exceeds the magnetic ordering temperature T_m~22 K. Secondly, we present neutron diffraction studies of Na0.85CoO2 with a magnetic field applied approximately parallel to the c axis. For fields in excess of ~8T a magnetic Bragg peak was observed at the (0,0,3) position in reciprocal space. We interpret this as a spin-flop transition of the A-type antiferromagnetic structure, and we show that the spin-flop field is consistent with the size of the anisotropy gap.

description: We perform a comparative study of two methods of determining the survival probabilities of low, intermediate, and high energy solar neutrinos that emphasizes the general agreement between the Large Mixing Angle (LMA) solution and extant solar neutrino data. The first analysis is oscillation parameter-independent and the second analysis involves an approximate calculation of the survival probabilities in the three energy ranges that depends only on oscillation parameters. We show that future experiments like BOREXino, CLEAN, Heron, LENS and MOON, that measure $pp$ and $^7$Be neutrinos, will facilitate a stringent test of the LMA solution independently of the Standard Solar Model (SSM), without recourse to earth-matter effects. Throughout, we describe the role of SSM assumptions on our results. If the LMA solution passes the test without needing to be modified, it may be possible to establish that $θ_x$ is nonzero at more than $2σ$ assuming the SSM prediction for the $pp$ flux is correct.

description: Van Hove points are special points in the energy dispersion, where the density of states exhibits analytic singularities. When a Van Hove point is close to the Fermi level, tendencies towards density wave orders, Pomeranchuk orders, and superconductivity can all be enhanced, often in more than one channel, leading to a competition between different orders and unconventional ground states. Here we consider the effects from higher-order Van Hove points, around which the dispersion is flatter than near a conventional Van Hove point, and the density of states has a power-law divergence. We argue that such points are present in intercalated graphene and other materials. We use an effective low-energy model for electrons near higher-order Van Hove points and analyze the competition between different ordering tendencies using an unbiased renormalization group approach. For purely repulsive interactions, we find that two key competitors are ferromagnetism and chiral superconductivity. For a small attractive exchange interaction, we find a new type of spin Pomeranchuk order, in which the spin order parameter winds around the Fermi surface. The supermetal state, predicted for a single higher-order Van Hove point, is an unstable fixed point in our case.

description: We describe an improved technique for using the backscattered phase from meteor radar echo measurements just prior to the specular point ($t_{0}$) to calculate meteor speeds and their uncertainty. Our method, which builds on earlier work of Cervera et al (1997), scans possible speeds in the Fresnel distance - time domain with a dynamic, sliding window and derives a best-speed estimate from the resultant speed distribution. We test the performance of our method, called pre-$t_{0}$ speeds by sliding-slopes technique (PSSST), on transverse scattered meteor echoes observed by the Middle Atmosphere Alomar Radar System (MAARSY) and the Canadian Meteor Orbit Radar (CMOR), and compare the results to time-of-flight and Fresnel transform speed estimates. Our novel technique is shown to produce good results when compared to both model and speed measurements using other techniques. We show that our speed precision is $\pm$5$\%$ at speeds less than 40 km/s and we find that more than 90$\%$ of all CMOR multi-station echoes have PSSST solutions. For CMOR data, PSSST is robust against the selection of critical phase value and poor phase unwrapping. Pick errors of up to $\pm$6 pulses for meteor speeds less than about 50 km/s produce errors of less than $\pm$5$\%$ of the meteoroid speed. In addition, the width of the PSSST speed Kernel density estimate (KDE) is used as a natural measure of uncertainty that captures both noise and $t_0$ pick uncertainties.

description: We report the detection of a potential cosmic radio transient source using the two stations of the Long Wavelength Array. The transient was detected on 18 October 2017 08:47 UTC near the celestial equator while reducing 10,240 hours of archival all-sky images from the LWA1 and LWA-SV stations. The detected transient at 34 MHz has a duration of 15 - 20 seconds and a flux density of 842 +/- 116 Jy at LWA1 and 830 +/- 92 Jy at LWA-SV. The transient source has not repeated, and its nature is not well understood. The Pan-STARRS optical telescope has detected a supernova that occurred on the edge of the position error circle of the transient on the same day.

description: The name 'sorption heat engines' is proposed for simple negative entropy generators that are driven by thermal cycling and work on alternating adsorption and desorption. These generators are in general not explicitly recognized as heat engines. Their mechanism is applicable to the fields of engineering, physics, chemistry, geology, and biology, in particular the origin of life. Four kinds of sorption heat engines are distinguished depending on the occurrence of changes in the adsorbent or adsorbate during the thermal cycle.

description: Increased productivity is a key to a healthy and thriving economy. Consequently, the trend in productivity, economywide, is one of the most closely watched of our common economic performance indicators. Agriculture, in particular, has been a very successful sector of the U.S. economy in terms of productivity growth. The U.S. farm sector has provided an abundance of output while using inputs efficiently. Agricultural productivity growth has been an important source of U.S. economic growth throughout the century, but the years since 1940 have seen an even faster growth in agricultural productivity. The annual average increase in productivity from 1948 to 1994 was 1.94 percent. This reflects an annual growth in output of 1.88 percent per year and an actual decline in agricultural inputs of 0.06 percent per year. This report describes changes in U.S. agricultural productivity, and its output and input components, for 1948-94. The report also discusses factors that have affected productivity trends and provides detailed, technical information about the USDA system for calculating productivity.

description: Farmer bankruptcies, bankruptcy rates, and related issues are explored from the beginning of modern bankruptcy legislation over a century ago. Farmer bankruptcies historically have been controversial because they are thought to indicate changes in the economic well-being and structure of the rural economy. Concerns about farmer bankruptcies were heightened twice during the past century. The first was from 1920 through the Great Depression and the second was during the 1980s. Bankruptcy data for Chapters 7, 11, and 13 exist for farmers for the 1899-1980 period, but there are no Chapter 7, 11, or 13 farmer bankruptcy data available beginning in 1980. However, data are available for the 1986-2002 period for Chapter 12, the Family Farmer Bankruptcy Act of 1986, that became effective on November 26, 1986, in response to the farm financial crisis of the 1980s. Some 22,519 Chapter 12 cases were filed through 2002, with the highest rate being in 1987. Farmer bankruptcy filing rates trended down after the late 1980s because of improved economic conditions and institutional changes.

description: Many Americans do not consume the recommended amount of fruits and vegetables. Almost half of Americans think eating more fruits and vegetables would make their diets healthier, so why don't they? One argument is that fruits and vegetables are expensive, especially when purchased fresh. According to an ERS study, a consumer can meet the recommendation of three servings of fruits and four servings of vegetables daily for 64 cents.

description: The U.S. Department of Agriculture provides subsidized credit to high-risk farm borrowers unable to obtain credit from commercial sources. To boost incomes and to relieve financial stress, Farm Service Agency programs can provide additional interest rate subsidies to borrowers. However, when market interest rates are low as in recent years, these additional subsidies are less effective in improving borrower income and financial performance. Directing these additional subsidies to beginning farmers and socially disadvantaged borrowers or reserving their use for more stressful economic periods may help control program costs while increasing benefits to borrowers and the public.

description: We apply the concept of users' emotion vectors (UVECs) and movies' emotion vectors (MVECs) as building components of Emotion Aware Recommender System. We built a comparative platform that consists of five recommenders based on content-based and collaborative filtering algorithms. We employed a Tweets Affective Classifier to classify movies' emotion profiles through movie overviews. We construct MVECs from the movie emotion profiles. We track users' movie watching history to formulate UVECs by taking the average of all the MVECs from all the movies a user has watched. With the MVECs, we built an Emotion Aware Recommender as one of the comparative platforms' algorithms. We evaluated the top-N recommendation lists generated by these Recommenders and found the top-N list of Emotion Aware Recommender showed serendipity recommendations.

description: Wide field BVI photometry and $^{12}$CO(1$\to$0) observations are presen ted in the region of the open cluster NGC 6520 and the dark molecular cloud Barnard~86. From the analysis of the optical data we find that the cluster is rather compact, with a radius of 1.0$\pm$0.5 arcmin, smaller than previous estimates. The cluster age is 150$\pm$50 Myr and the reddening E$_{B-V}$=0.42$\pm$0.10. The distance from the Sun is estimated to be 1900$\pm$100 pc, and it is larger than previous estimates. We finally derive basic properties of the dark nebula Barnard 86 on the assumption that it lies at the same distance of the cluster.
