description: This work presents the GPU acceleration of the open-source code CaNS for very fast massively-parallel simulations of canonical fluid flows. The distinct feature of the many-CPU Navier-Stokes solver in CaNS is its fast direct solver for the second-order finite-difference Poisson equation, based on the method of eigenfunction expansions. The solver implements all the boundary conditions valid for this type of problems in a unified framework. Here, we extend the solver for GPU-accelerated clusters using CUDA Fortran. The porting makes extensive use of CUF kernels and has been greatly simplified by the unified memory feature of CUDA Fortran, which handles the data migration between host (CPU) and device (GPU) without defining new arrays in the source code. The overall implementation has been validated against benchmark data for turbulent channel flow and its performance assessed on a NVIDIA DGX-2 system (16 Tesla V100 32Gb, connected with NVLink via NVSwitch). The wall-clock time per time step of the GPU-accelerated implementation is impressively small when compared to its CPU implementation on state-of-the-art many-CPU clusters, as long as the domain partitioning is sufficiently small that the data resides mostly on the GPUs. The implementation has been made freely available and open-source under the terms of an MIT license.

description: Large expenses associated with rice production and dependence on energy related inputs like fuel and fertilizer in particular compel rice producers to use management practices that are input efficient and result in least cost. This study uses data envelopment analysis (DEA) to calculate technical efficiency (TE), allocative efficiency (AE), and economic efficiency (EE) for rice production in Arkansas at the field level using data from 137 fields enrolled in the University of Arkansas, Rice Research Verification Program (RRVP) from 2005 to 2011. Efficiency scores for RRVP fields are compared with those obtained from developing rice producing countries. Economic efficiency scores are also compared across RRVP fields using alternative management practices. The results indicate the majority of RRVP fields have high TE scores with a mean TE score of 0.899. Over half the fields in the RRVP achieve full technical efficiency (TE scores equal to 1). Mean AE and EE scores for RRVP fields (AE = 0.696; EE = 0.625) fall within the range of mean AE and EE scores reported for developing countries producing rice. Alternative management practices appear to have an impact EE scores. Fields planted to hybrid, Clearfield-hybrid combinations, and medium grain varieties along with fields with a zero-grade and fields using multiple inlet irrigation produced higher EE scores relative to other RRVP fields.

description: We have grown RFe2Ge2 single crystals for R = Y and ten members of the lanthanide series (Pr, Nd, Sm, Gd-Tm, Lu) using Sn flux as the solvent. The method yields clean, high quality crystal plates as evidenced by residual resistivities and RRR values in the range of 3-12 uOhm cm and 20-90 respectively. The crystals are also virtually free of magnetic impurities or secondary phases, allowing the study of the intrinsic anisotropic magnetic behavior of each compound. Characterization was made with X-Ray diffraction, and temperature and field dependent magnetization, specific heat and resistivity. Very strong anisotropies arising mostly from CEF effects were observed for all magnetic rare earths except Gd. Antiferromagnetic ordering occurred at temperatures between 16.5 K (Nd) and 1.1 K (Ho) that roughly scale with the de Gennes factor for the heavy rare earths. For some members there is also a lower temperature transition associated with changes in the magnetic structure. Tm did not order down to 0.4 K, and appears to be a van Vleck paramagnet. All members which ordered above 2 K showed a metamagnetic transition at 2 K for fields below 70 kOe. The calculated effective moments per rare earth atom are close to the expected free ion values of R^3+ except for Sm which displays anomalous behavior in the paramagnetic state. The non-magnetic members of this series (Y, Lu) are characterized by an unusually large electronic specific heat coefficient (gamma ~ 60 mJ/mol K^2) and temperature-independent susceptibility term (chi_0 ~ 0.003 emu/mol), indicative of a relatively large density of states at the Fermi surface.

description: The phenomenon of low economic growth in resource-rich regions is recognized as the “resource curse”. This research empirically shows the existence of a resource curse at the U.S. state level. Of two widely offered explanations for the resource curse, our analysis supports the crowding-out effect in the U.S. rather than the institutional explanation. Investment and R&D are the two main crowded-out factors.

description: Since 1952, several technical bulletins' that deal with the demand and price structure for grains have been published by the United States Department of Agriculture. Research results from three of these bulletins can be used in an integrated way to consider possible effects of alternative governmental price-support policies for wheat and corn. This article discusses the ways in which such analyses can be made, with emphasis on the effects of alternative assumptions on the conclusions reached. It demonstrates the power of the modern structural approach for studies of this sort. Results obtained and conclusions reached in this article come directly from the application of certain systems of economic relationships based on specified assumptions. Although it is believed that these results and conclusions throw light on the alternative policies analyzed, they in no sense represent official findings of the United States Department of Agriculture. They are presented primarily to illustrate the kinds of analyses that can be made from an approach of this sort.

description: We have studied the zero temperature phase diagram of XYZ model in the presence of transverse magnetic field. We show that small anisotropy (0 =< Delta <1) is not relevant to change the universality class. The phase diagram consists of two antiferromagnetic ordering and a paramagnetic phases. We have obtained the critical exponents, fixed points and running of coupling constants by implementing the standard quantum renormalization group. The continuous phase transition from antiferromagnetic (spin-flop) phase to a paramagnetic one is in the universality class of Ising model in transverse field. Numerical exact diagonalization has been done to justify our results. We have also addressed on the application of our findings to the recent experiments on Cs_2CoCl_4.

description: We use a combination of extreme value theory, survival analysis and computer-intensive methods to analyze the mortality of Italian and French semi-supercentenarians for whom there are validated records. After accounting for the effects of the sampling frame, there appears to be a constant rate of mortality beyond age 108 years and no difference between countries and cohorts. These findings are consistent with previous work based on the International Database on Longevity and suggest that any physical upper bound for humans is so large that it is unlikely to be approached. There is no evidence of differences in survival between women and men after age 108 in the Italian data and the International Database on Longevity; however survival is lower for men in the French data.

description: Extrachromosomal circular DNA (eccDNA) exists outside the linear chromosomes and, while present in normal cells, takes on a more critical role in cancer [1]. It can harbor oncogenes and regulatory elements that drive tumorigenesis. In the case of colon cancer, which is the third most common cancer worldwide [2], eccDNA may be especially impactful. It is thought to play a key role in driving disease progression and enhancing oncogene expression.

description: This article presents newly developed national estimates of average income, per farm and per person in the farm family, for each economic class of farm in 1949. Aggregates and averages of farm income and expenditures are published regularly in considerable detail in The Farm Income Situation. Breakdowns are provided by regions and States and also in such terms as individual commodities and commodity groups, money and nonmoney income, and the various types of expenditures. But historical data by economic class of farm are not available to permit analyses of income trends on commercial farms on the one hand and noncommercial farms on the other. That is, estimates are for all farms in the United States, from the very small part-time and residential farms to the very large farms with sales valued at $100,000 or more.

description: Active re-identification attacks pose a serious threat to privacy-preserving social graph publication. Active attackers create fake accounts to build structural patterns in social graphs which can be used to re-identify legitimate users on published anonymised graphs, even without additional background knowledge. So far, this type of attacks has only been studied in the scenario where the inherently dynamic social graph is published once. In this paper, we present the first active re-identification attack in the more realistic scenario where a dynamic social graph is periodically published. The new attack leverages tempo-structural patterns for strengthening the adversary. Through a comprehensive set of experiments on real-life and synthetic dynamic social graphs, we show that our new attack substantially outperforms the most effective static active attack in the literature by increasing the success probability of re-identification by more than two times and efficiency by almost 10 times. Moreover, unlike the static attack, our new attack is able to remain at the same level of effectiveness and efficiency as the publication process advances. We conduct a study on the factors that may thwart our new attack, which can help design graph anonymising methods with a better balance between privacy and utility.

description: We give quantum circuits that simulate an arbitrary two-qubit unitary operator up to global phase. For several quantum gate libraries we prove that gate counts are optimal in worst and average cases. Our lower and upper bounds compare favorably to previously published results. Temporary storage is not used because it tends to be expensive in physical implementations. For each gate library, best gate counts can be achieved by a single universal circuit. To compute gate parameters in universal circuits, we only use closed-form algebraic expressions, and in particular do not rely on matrix exponentials. Our algorithm has been coded in C++.

Proof techniques in v2 are noticeably revamped: they now rely less on circuit identities and more on directly-computed invariants of two-qubit operators. This makes proofs more constructive and easier to interpret as algorithms

description: The computation of genomic distances has been a very active field of computational comparative genomics over the last 25 years. Substantial results include the polynomial-time computability of the inversion distance by Hannenhalli and Pevzner in 1995 and the introduction of the double-cut and join (DCJ) distance by Yancopoulos et al. in 2005. Both results, however, rely on the assumption that the genomes under comparison contain the same set of unique markers (syntenic genomic regions, sometimes also referred to as genes). In 2015, Shao, Lin and Moret relax this condition by allowing for duplicate markers in the analysis. This generalized version of the genomic distance problem is NP-hard, and they give an ILP solution that is efficient enough to be applied to real-world datasets. A restriction of their approach is that it can be applied only to balanced genomes, that have equal numbers of duplicates of any marker. Therefore it still needs a delicate preprocessing of the input data in which excessive copies of unbalanced markers have to be removed. In this paper we present an algorithm solving the genomic distance problem for natural genomes, in which any marker may occur an arbitrary number of times. Our method is based on a new graph data structure, the multi-relational diagram, that allows an elegant extension of the ILP by Shao, Lin and Moret to count runs of markers that are under- or over-represented in one genome with respect to the other and need to be inserted or deleted, respectively. With this extension, previous restrictions on the genome configurations are lifted, for the first time enabling an uncompromising rearrangement analysis. Any marker sequence can directly be used for the distance calculation. The evaluation of our approach shows that it can be used to analyze genomes with up to a few ten thousand markers, which we demonstrate on simulated and real data.

description: Security vulnerabilities play a vital role in network security system. Fuzzing technology is widely used as a vulnerability discovery technology to reduce damage in advance. However, traditional fuzzing techniques have many challenges, such as how to mutate input seed files, how to increase code coverage, and how to effectively bypass verification. Machine learning technology has been introduced as a new method into fuzzing test to alleviate these challenges. This paper reviews the research progress of using machine learning technology for fuzzing test in recent years, analyzes how machine learning improve the fuzz process and results, and sheds light on future work in fuzzing. Firstly, this paper discusses the reasons why machine learning techniques can be used for fuzzing scenarios and identifies six different stages in which machine learning have been used. Then this paper systematically study the machine learning based fuzzing models from selection of machine learning algorithm, pre-processing methods, datasets, evaluation metrics, and hyperparameters setting. Next, this paper assesses the performance of the machine learning models based on the frequently used evaluation metrics. The results of the evaluation prove that machine learning technology has an acceptable capability of categorize predictive for fuzzing. Finally, the comparison on capability of discovering vulnerabilities between traditional fuzzing tools and machine learning based fuzzing tools is analyzed. The results depict that the introduction of machine learning technology can improve the performance of fuzzing. However, there are still some limitations, such as unbalanced training samples and difficult to extract the characteristics related to vulnerabilities.

description: Bitcoin-NG is among the first blockchain protocols to approach the \emph{near-optimal} throughput by decoupling blockchain operation into two planes: leader election and transaction serialization. Its decoupling idea has inspired a new generation of high-performance blockchain protocols. However, the existing incentive analysis of Bitcoin-NG has several limitations. First, the impact of network capacity is ignored. Second, an integrated incentive analysis that jointly considers both key blocks and microblocks is still missing. In this paper, we aim to address these two limitations. First, we propose a new incentive analysis that takes the network capacity into account, showing that Bitcoin-NG can still maintain incentive compatibility against the microblock mining attack even under limited network capacity. Second, we leverage a Markov decision process (MDP) to jointly analyze the incentive of both key blocks and microblocks, showing that the selfish mining revenue of Bitcoin-NG is a little higher than that in Bitcoin only when the selfish miner controls more than 35\% of the mining power. We hope that our in-depth incentive analysis for Bitcoin-NG can shed some light on the mechanism design and incentive analysis of next-generation blockchain protocols.

description: A partial wave analysis using the basis of the total angular momentum operator J_3 is carried out for the first order Born amplitude of a Dirac particle in an Aharonov-Bohm (AB)potential. It is demonstrated that the s-partial wave contributes to the scattering amplitude in contrast to the case with scalar non-relativistic particles.We suggest that this explains the fact that the first order Born amplitude of a Dirac particle coincides with the exact amplitude expanded to the same order, where it does not for a scalar particle. An interesting algebra involving the Dirac velocity operator and the angular observables is discovered and its consequences are exploited.

description: As part of an expanded research program begun about 2 years ago by the Agricultural Estimates Division, Agricultural Marketing Service, pilot interview farm surveys were conducted in 10 Southern States during June 1954 and June 1955, and will be continued, in an effort to develop an improved crop and livestock estimating system. These surveys are somewhat unusual in that their main purpose is not to grind out estimates on a variety of agricultural items, but to study the operational and statistical problems that arise. Although emphasis is on research, the surveys are conducted under simulated operating conditions so that the transition from "research" to an operating program should be a natural development as the work progresses. This paper discusses technical aspects of the surveys.
Raman Scattered He II $λ$ 6545 Line in the Symbiotic Star V1016 Cygni

description: We present a spectrum of the symbiotic star V1016 Cyg observed with the 3.6 m Canada-France-Hawaii Telescope, in order to illustrate a method to measure the covering factor of the neutral scattering region around the giant component with respect to the hot emission region around the white dwarf component. In the spectrum, we find broad wings around H$α$ and a broad emission feature around 6545${\rm Å}$ that is blended with the [N II]$ λ$ 6548 line. These two features are proposed to be formed by Raman scattering by atomic hydrogen, where the incident radiation is proposed to be UV continuum radiation around Ly$β$ in the former case and He II $λ$ 1025 emission line arising from $n=6\to n=2$ transitions for the latter feature. We remove the H$α$ wings by a template Raman scattering wing profile and subtract the [N II] $λ$ 6548 line using the 3 times stronger [N II] $λ$ 6583 feature in order to isolate the He II Raman scattered 6545 Åline. We obtain the flux ratio $F_{6545}/F_{6560}=0.24$ of the He II $λ$ 6560 emission line and the 6545 Åfeature for V1016 Cyg. Under the assumption that the He II emission from this object is isotropic, this ratio is converted to the ratio $Φ_{6545}/Φ_{1025}=0.17$ of the number of the incident photons and that of the scattered photons. This implies that the scattering region with H I column density $N_{HI}\ge 10^{20}{\rm cm^{-2}}$ covers 17 per cent of the emission region. By combining the presumed binary period $\sim 100$ yrs of this system we infer that a significant fraction of the slow stellar wind from the Mira component is ionized and that the scattering region around the Mira extends a few tens of AU, which is closely associated with the mass loss process of the Mira component.

Demand and Price Analysis
Production Economics

description: No one knows exactly what the demands for farm products will be in 1960 and 1975. Nor can anyone foresee the exact supplies of agricultural commodities in these years. Yet farmers, legislators, and administrators of agricultural programs cannot work entirely in the dark. They must base their plans upon the best possible estimates of future demand and supply conditions. They expect the economist and the statistician to analyze current and prospective trends and to make useful projections indicating the probable direction of major changes in the future. With these needs in mind, the United States Department of Agriculture in the past has made and published several projections of the long-range demand for and supply of farm products. The present report brings up to datr the Department's projections of potential demand for farm products around 1960 and 1975. While these projections show a substantial increase in total demand for farm products, they indicate some sharp differences in trends. For example, they point to sizable increases in the demand for livestock products and fruits and vegetables, and decidedly more limited increases for food grains and potatoes. Projections of demands and supplies are made on the basis of certain assumptions. We have assumed a stable price situation and a trend toward world peace. We have also made assumptions concerning such factors as population, labor force, employment, hours of work, and productivity. The projections shown in this report are not forecasts. Rather, they indicate what trends we would expect in the demand for farm products under a set of assumptions. The projections could go wrong if we suffered a long business depression, or if we became involved in a largescale war, or if nutritional findings or consumer preferences brought changes in consumption patterns appreciably different from those indicated in this report.

Comparative magnetotransport and Tc measurements on kappa-(BEDT-TTF)2Cu(SCN)2 under pressure

description: We compare magnetotransport measurements under pressure on the organic superconductor $κ$-(BEDT-TTF)$_{2}$Cu(SCN)$_{2}$ with different pressure-media and discover that the results are pressure media dependent. This pressure-medium dependence is thought to originate from the difference in thermal contraction between the very soft and highly anisotropic sample and the isotropically contracting, but solid pressure medium, thus resulting in non-hydrostatic pressure on the sample. However, comparison of pressure measurements with different media reveals a pressure-medium independent correlation between the superconducting transition temperature, T$_{\rm c}$, and the size of the quasi 2-dimensional Fermi surface pocket and thus the quasi 2-dimensional carrier density in $κ$-(BEDT-TTF)$_{2}$Cu(SCN)$_{2}$. The observed pressure-induced increase in the quasi 2-dimensional carrier density can be interpreted as a transfer of carriers from quasi 1-dimensional Fermi surface sections, reminiscent of a mechanism in cuprate superconductors, where pressure is known to transfer carriers from the insulating charge reservoir layers into the conducting cuprate sheets.

description: We discuss recent developments in the formulation of a Statistical Mechanics approach to non thermal systems, such as granular media. We review a few important numerical results on the assessment of Edwards' theory and, in particular, we apply these ideas to study a mean field model of a hard sphere binary mixture under gravity, which can be fully analytically investigated. As a consequence, we derive the rich phase diagram and predict the features of segregation patterns of the mixture.

description: By fixing a reference frame in spacetime, it is possible to split the Euler-Lagrange equations associated with a degenerate Lagrangian into purely evolutionary equations and constraints on the allowed Cauchy data with respect to the notion of Space and Time associated with the given reference frame. In the context of Classical Electrodynamics, we introduce a "covariantization procedure" that allows to invert the perspective and to recover a full-fledged covariant formulation of Maxwell's equations starting only with constraint equations (i.e., Gauss' law and the local version of the law of conservation of magnetic flux) as perceived in a sufficient number of (inertial) reference frames on Minkowski spacetime.

Risk and Uncertainty

description: Fruit and nut production in Oregon and other important producing areas is highly commercialized. Sales of many of these commodities are controlled by Federal marketing agreements to provide for orderly marketing of each year's crop. Officers of grower and processor organizations who are charged with the administration of the programs need accurate early-season forecasts of prospective production and quality of the product. Monthly production forecasts are published during the growing season by the Crop Reporting Service as part of the overall crop and livestock estimating program. However, the complexity of marketing problems faced by producers and their organizations has built up pressures for more detail and greater precision in such forecasts. This paper reports on a study being made on filberts in Oregon; the approach to the problem is typical of the approach now under study in several areas.
EVALUATING THE EFFICACY OF COLLABORATIVE AND EXPERIMENTAL TEACHING METHODS ON ACADEMIC ACHIEVEMENT IN BASIC TECHNOLOGY

description: This research investigated the effects of cooperative practicum, experimental demonstration, and lecture approaches on the academic performance of basic technology students at Edo State. This study employed a 3x2 pretest, posttest, control group quasi-experimental design. The survey included a total of 29,000 students who were studying basic technology. The research sample consisted of 312 JSII basic technology students from six public mixed junior secondary schools in Edo State. Data collection was conducted using the Basic Technology Achievement Test (BTAT). The validity of the BAT was confirmed by three experts. A Kuder-Richardson 21 test was employed to assess the reliability of the BTAT. The obtained reliability coefficient value was 0.80. Prior to and following treatment, the BTAT was administered as both a pretest and a posttest. Analysis of the gathered data was conducted using mean, standard deviation, and ANCOVA. Significantly different mean achievement levels were seen among students who received instruction in fundamental technology through collaborative practicum, experimental demonstration and lecture method. According to Scheffe's post-hoc test, the direction of significance shifts from the collaborative practicum to the experimental demonstration and lecture method, respectively. According to the study's findings, collaborative practicum, experimental demonstration, and lecture method can all help students retain basic technologies and accomplish better academically. However, collaborative practicum was shown to be the most successful, followed by experimental demonstration. The study comes to another conclusion once more: when interaction is taken into account, students' academic achievement in basic technology was not impacted by their sex in conjunction with the utilisation of collaborative practicum, experimental demonstration, and lecture. In order to increase students' active participation and interaction during instruction, basic technology teachers at the junior secondary school level are advised to implement collaborative practicum and experimental demonstration in their instruction. This recommendation is based on the study's findings
