description: We approximately compute the normalization constant of the first infrared renormalon of the pole mass (and the singlet static potential). Estimates of higher order terms in the perturbative relation between the pole mass and the $\MS$ mass (and in the relation between the singlet static potential and $α_s$) are given. We define a matching scheme (the renormalon subtracted scheme) between QCD and any effective field theory with heavy quarks where, besides the usual perturbative matching, the first renormalon in the Borel plane of the pole mass is subtracted. A determination of the bottom $\MS$ quark mass from the $Υ(1S)$ system is performed with this new scheme and the errors studied. Our result reads $m_{b,\MS}(m_{b,\MS})=4 210^{+90}_{-90}({\rm theory})^{-25}_{+25}(α_s)$ MeV. Using the mass difference between the $B$ and $D$ meson, we also obtain a value for the charm quark mass: $m_{c,\MS}(m_{c,\MS})=1 210^{+70}_{-70}({\rm theory})^{+65}_{-65}(m_{b,\MS})^{-45}_{+45}(λ_1)$ MeV. We finally discuss upon eventual improvements of these determinations.

description: Retained ownership is a marketing strategy that can be used by cow-calf operators. Therefore, we analyze the profitability of retained ownership over the past decade. We also determine the impact of animal characteristics (e.g., average daily gain, feed conversion) and producer choice decisions (e.g., placement weight, placement season, days on feed) on retained ownership profitability. Data from 2005 to 2015 on 2,953 head of cattle originating in Tennessee and finished in Iowa using a retained ownership strategy were collected. A mixed model was developed with fixed effects for animal characteristics and producer choice variables and random effects for the feedlot, farm origin and the year cattle were harvested. Results indicate that placement weight, placement season, days on feed, animal health and animal sex impacted retained ownership profitability. Our findings could be useful for cow-calf producers to develop more profitable production and marketing strategies.

description: The purpose of this study is to analyze the implications of controlling the supply and demand growth rates in the veterinary medicine industry. Particular focus will be the effects on income within and between large and small animal practices. Essentially, the AVMA, in cooperation of the veterinary schools, has a form of market power to control the supply growth of veterinarians entering the market each year. This power will be explored using an equilibrium displacement model (EDM). By using the AVMA’s various data sets, demand and supply curves, along with associated elasticities, can be estimated. These results will be used to simulate various policies in regards to supply. This will be done for the industry on an aggregate level, as well as for certain sectors to test cross sector effects. We anticipate the results to show the effects of various policy tools that the AVMA can implement within the veterinary medicine industry. Since the demand for veterinary services is considered to be slower in growth than the supply, there is need to better understand the options that the veterinary industry can employ in order to prevent a decline in veterinarian incomes.

description: Bluetooth is one of the most established technologies for short range digital wireless data transmission. With the advent of wearables and the Internet of Things (IoT), Bluetooth has again gained importance, which makes security research and protocol optimizations imperative. Surprisingly, there is a lack of openly available tools and experimental platforms to scrutinize Bluetooth. In particular, system aspects and close to hardware protocol layers are mostly uncovered. We reverse engineer multiple Broadcom Bluetooth chipsets that are widespread in off-the-shelf devices. Thus, we offer deep insights into the internal architecture of a popular commercial family of Bluetooth controllers used in smartphones, wearables, and IoT platforms. Reverse engineered functions can then be altered with our InternalBlue Python framework---outperforming evaluation kits, which are limited to documented and vendor-defined functions. The modified Bluetooth stack remains fully functional and high-performance. Hence, it provides a portable low-cost research platform. InternalBlue is a versatile framework and we demonstrate its abilities by implementing tests and demos for known Bluetooth vulnerabilities. Moreover, we discover a novel critical security issue affecting a large selection of Broadcom chipsets that allows executing code within the attacked Bluetooth firmware. We further show how to use our framework to fix bugs in chipsets out of vendor support and how to add new security features to Bluetooth firmware.

description: Beginning October 2015, McDonalds restaurants offer a limited breakfast menu all day in hopes of catalyzing business growth in the United States. The decision to expand the menu comes at a time when key breakfast menu inputs, i.e. eggs, are in shortage due to the outbreak of highly pathogenic avian influenza (HPAI) in U.S. layer flocks. The first case of HPAI was announced December 2014 with the last reported detection occurring June 2015 affecting more than 48 million birds. The outbreak led to depopulation of millions of infected birds, limiting supply, which has led to higher retail prices to consumers both direct and indirect consumption. The increase in demand by McDonalds is expected to further exacerbate this issue. Using a partial equilibrium model of U.S. layer flocks, the welfare impacts of an increase in demand coupled with a decrease in supply can be estimated. By using HPAI outbreak supply shocks and a stochastic estimation of demand increases due to all day breakfast by McDonald’s, the total welfare are estimated to have an additional negative $220 thousand marginal impact to consumers and a positive $33 thousand impact to producers.

description: This work analyzes the differences in collaboration behavior between males and females among a particular type of scholars: top scientists, and as compared to non top scientists. The field of observation consists of the Italian academic system and the co-authorships of scientific publications by 11,145 professors. The results obtained from a cross-sectional analysis covering the five-year period 2006-2010 show that there are no significant differences in the overall propensity to collaborate in the top scientists of the two genders. At the level of single disciplines there are no differences in collaboration behavior, except in the case of: i) international collaborations, for Mathematics and Chemistry - where the propensity for collaboration is greater for males; and ii) extramural domestic collaborations in Physics, in which it is the females that show greater propensity for collaboration. Because international collaboration is positively correlated to research performance, findings can inform science policy aimed at increasing the representation of female top performers.

description: An unconventional superconducting phase is explored developing out of a non Fermi-liquid phase of the two-channel Anderson lattice model. It is characterized by a composite order parameter comprising of a local spin or orbital degree of freedom bound to triplet Cooper pairs with an isotropic and a nearest neighbour form factor. The superconducting transition temperature peaks in the moderate intermediate valence regime and vanishes at integral valence. The gap function is non analytic and odd in frequency, and a pseudo-gap develops in the conduction electron density of states which vanishes as $|ω|$ close to $ω=0$.

description: A search for WW production from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of 13 TeV. The analyzed data set corresponds to an integrated luminosity of 77.4 fb$^{-1}$, collected using the CMS detector at the LHC in 2016 and 2017. Multivariate classifiers are used to discriminate between the signal and the dominant background processes. A maximum likelihood fit is performed to extract the signal cross section. This leads to the first evidence for WW production via double-parton scattering, with a significance of 3.9 standard deviations. The measured inclusive cross section is 1.41 $\pm$ 0.28 (stat) $\pm$ 0.28 (syst) pb.

description: This article examines how well two parallel behavioral approaches, one in economics and the other in anthropology, explain the economic evolution of Neolithic societies, particularly their transit from foraging to agriculture. Both assume rational optimizing behavior. It is argued that satisficing theories provide a superior explanation of transition (and non-transition) by some hunter-gatherers. Furthermore, many of the concepts associated with neoclassical economics are shown to be inadequate for analyzing the choice problems involved. Moreover, it is argued that all behavioral theories considering the relationship between human behavior and economic evolution need to pay attention to the way that decision-making is embedded in social structures. It is unlikely that a single theory will be able to explain the economic evolution of all societies when social structures and other relevant variables differ between communities.

description: We report the most complete analysis to date of observations of the Cosmic Microwave Background (CMB) obtained during the 1998 flight of BOOMERANG. We use two quite different methods to determine the angular power spectrum of the CMB in 20 bands centered at l = 50 to 1000, applying them to 50% more data than has previously been analyzed. The power spectra produced by the two methods are in good agreement with each other, and constitute the most sensitive measurements to date over the range 300 < l < 1000. The increased precision of the power spectrum yields more precise determinations of several cosmological parameters than previous analyses of BOOMERANG data. The results continue to support an inflationary paradigm for the origin of the universe, being well fit by a 13.5 Gyr old, flat universe composed of approximately 5% baryonic matter, 30% cold dark matter, and 65% dark energy, with a scale invariant initial density perturbations.

description: Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of out-of-time order correlators (OTOCs) with quantum chaos. The quantum-classical correspondence between the OTOC exponential growth and chaos in the classical limit has indeed been corroborated theoretically for some systems and there are several projects to do the same experimentally. The Dicke model, in particular, which has a regular and a chaotic regime, is currently under intense investigation by experiments with trapped ions. We show, however, that for experimentally accessible parameters, OTOCs can grow exponentially also when the Dicke model is in the regular regime. The same holds for the Lipkin-Meshkov-Glick model, which is integrable and also experimentally realizable. The exponential behavior in these cases are due to unstable stationary points, not to chaos.

description: Influenza A viruses (IAVs) continue to cause tremendous economic losses to the global animal industry and respiratory diseases and deaths among humans. The nuclear import of the vRNP complex, composed of polymerase basic protein 1 (PB1), polymerase basic protein 2 (PB2), polymerase acidic protein (PA), nucleoprotein (NP), and viral RNA, is essential for the efficient replication of IAV. Host factors involved in this process can be targeted for the development of countermeasures against IAV infection. Here, we found that Ankyrin Repeat and BTB Domain Containing 1 (ABTB1) promotes the replication of IAV, and positively regulates the nuclear import of the vRNP complex. ABTB1 did not interact directly with NP, indicating that ABTB1 plays an indirect role in facilitating the nuclear import of the vRNP complex. Immunoprecipitation and mass spectrometry revealed that Tripartite Motif Containing 4 (TRIM4) interacts with ABTB1. We found that TRIM4 relies on its E3 ubiquitin ligase activity to inhibit the replication of IAV by targeting and degrading NP within the incoming vRNP complex as well as the newly synthesized NP. ABTB1 interacted with TRIM4, leading to TRIM4 degradation through the proteasome system. Notably, ABTB1-mediated degradation of TRIM4 blocked the effect of TRIM4 on NP stability, and largely counteracted the inhibitory effect of TRIM4 on IAV replication. Our findings define a novel role for ABTB1 in aiding the nuclear import of the vRNP complex of IAV by counteracting the destabilizing effect of TRIM4 on the viral NP protein.

description: We present a detailed analysis of epsilon'/epsilon within the Standard Model, taking into account the strong enhancement through final-state interactions identified in refs. [1] and [2]. The relevant hadronic matrix elements are fixed at leading order in the 1/N_C expansion, through a matching procedure between the effective short-distance Lagrangian and its corresponding low-energy description in Chiral Perturbation Theory. All large logarithms are summed up, both at short and long distances. Two different numerical analyses are performed, using either the experimental or the theoretical value for epsilon, with compatible results. We obtain Re(epsilon'/epsilon) = (1.7 +- 0.9)*10^{-3}. The error is dominated by the uncertainty in the value of the strange quark mass and the estimated corrections from unknown 1/N_C-suppressed local contributions. A better estimate of the strange quark mass would reduce the uncertainty to about 30%. The Standard Model prediction agrees with the present experimental world average Re(epsilon'/epsilon) =(1.93 +- 0.24)*10^{-3}.

description: CaBi$_2$ is a recently discovered type-I superconductor with $T_c=2$~K and a layered crystal structure. In this work electronic structure, lattice dynamics and electron-phonon interaction are studied, with a special attention paid to the influence of the spin-orbit coupling (SOC) on above-mentioned quantities. We find, that in the scalar-relativistic case (without SOC), electronic structure and electron-phonon interaction show the quasi-two dimensional character. Strong Fermi surface nesting is present, which leads to appearance of the Kohn anomaly in the phonon spectrum and enhanced electron-phonon coupling for the phonons propagating in the Ca-Bi atomic layers. However, strong spin-orbit coupling in this material changes the topology of the Fermi surface, reduces the nesting and the electron-phonon coupling becomes weaker and more isotropic. The electron-phonon coupling parameter $λ$ is reduced by SOC almost twice, from 0.94 to 0.54, giving even stronger effect on the superconducting critical temperature $T_c$, which drops from 5.2~K (without SOC) to 1.3~K (with SOC). Relativistic values of $λ$ and $T_c$ remain in a good agreement with experimental findings, confirming the general need for including SOC in analysis of the electron-phonon interaction in materials containing heavy elements.

description: We present the results of a 7-12 GHz phased-array study of the Galactic center magnetar J1745-2900 with the Karl G. Jansky Very Large Array (VLA). Using data from two 6.5 hour observations from September 2014, we find that the average profile is comprised of several distinct components at these epochs and is stable over $\sim$day timescales and $\sim$GHz frequencies. Comparison with additional phased VLA data at 8.7 GHz shows significant profile changes on longer timescales. The average profile at 7-12 GHz is dominated by the jitter of relatively narrow pulses. The pulses in each of the four main profile components seen in September 2014 are uncorrelated in phase and amplitude, though there is a small but significant correlation in the occurrence of pulses in two of the profile components. Using the brightest pulses, we measure the dispersion and scattering parameters of J1745-2900. A joint fit of 38 pulses gives a 10 GHz pulse broadening time of $τ_{\rm sc, 10} = 0.09 \pm 0.03~\rm ms$ and a dispersion measure of ${\rm DM} = 1760^{+2.4}_{-1.3}~{\rm pc~cm}^{-3}$. Both of these results are consistent with previous measurements, which suggests that the scattering and dispersion measure of J1745-2900 may be stable on timescales of several years.

description: The objective of this paper is to evaluate the economic returns and risk associated with alternative crop residue management and tillage strategies in two different locations in Mississippi over the 2012 to 2014 crop years. It was found that in the irrigated production systems employed at Stoneville, there was no difference in the burn versus no-burn treatments. At the dryland production site in Verona, the TerraTill-bedroll system appears to be a consistently high performer for corn production. For Verona, no consistent results seem to appear for soybean production between the alternate tillage systems. At the irrigated site in Stoneville, no tillage system for either corn or soybean production seems to be consistently superior in generating net returns above tillage systems and residue management system.
Large Deviation of the Density Profile in the Steady State of the Open Symmetric Simple Exclusion Process

description: We consider an open one dimensional lattice gas on sites $i=1,...,N$, with particles jumping independently with rate 1 to neighboring interior empty sites, the {\it simple symmetric exclusion process}. The particle fluxes at the left and right boundaries, corresponding to exchanges with reservoirs at different chemical potentials, create a stationary nonequilibrium state (SNS) with a steady flux of particles through the system. The mean density profile in this state, which is linear, describes the typical behavior of a macroscopic system, i.e., this profile occurs with probability 1 when $N \to \infty$. The probability of microscopic configurations corresponding to some other profile $ρ(x)$, $x = i/N$, has the asymptotic form $\exp[-N {\cal F}(\{ρ\})]$; $\cal F$ is the {\it large deviation functional}. In contrast to equilibrium systems, for which ${\cal F}_{eq}(\{ρ\})$ is just the integral of the appropriately normalized local free energy density, the $\cal F$ we find here for the nonequilibrium system is a nonlocal function of $ρ$. This gives rise to the long range correlations in the SNS predicted by fluctuating hydrodynamics and suggests similar non-local behavior of $\cal F$ in general SNS, where the long range correlations have been observed experimentally.

description: V CVn is a semiregular variable star with a V-band amplitude of $\approx2$ mag. This star has an unusually high amplitude of polarimetric variability: up to 6 per cent. It also exhibits a prominent inverse correlation between the flux and the fraction of polarization and a substantial constancy of the angle of polarization. To figure out the nature of these features, we observed the object using the Differential Speckle Polarimetry at three bands centered on 550, 625 and 880 nm using the 2.5-m telescope of Sternberg Astronomical Institute. The observations were conducted on 20 dates distributed over three cycles of pulsation. We detected an asymmetric reflection nebula consisting of three regions and surrounding the star at the typical distance of 35 mas. The components of the nebula change their brightness with the same period as the star, but with significant and different phase shifts. We discuss several hypotheses that could explain this behavior.

description: It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale M_{susy} through the formula Lambda \sim M_p^4 (M_{susy}/M_p)^8. We point out that a similar relation naturally arises in the codimension two solutions of warped space-time varying compactifications of string theory in which non-isotropic stringy moduli induce a small but positive cosmological constant.

description: We have investigated whether the nu_4 feature of NH4+ is a viable candidate for the 6.85 micron absorption band seen towards embedded young stellar objects. To produce NH4+ astrophysical ice analogs consisting of H2O, CO2, NH3 and O2 were UV photolysed. The IR spectra reveal peaks that are identified with the NH4+, NO2-, NO3- and HCO3- ions. It is shown that the NH4+ matches two absorption features that are observed towards embedded young stellar objects, i.e., the strong 6.85 micron feature and the 3.26 micron feature. The characteristic redshift with temperature of the interstellar 6.85 micron feature is well reproduced. The abundance of NH4+ in interstellar ices would be typically 10 % relative to H2O. The experiments show that the counterions produce little distinct spectral signature but rather a pseudo-continuum if a variety of them is present in a H2O dominated environment. The anions could therefore go undetected in IR spectra of interstellar ice. In the ISM, where additional mechanisms such as surface chemistry and additional elements such as sulfur are available many acids and an even wider variety of anions could be produced. These components may be detectable once the ices sublime, e.g, in hot cores.

Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: The dynamics of a prey-predator system with foraging facilitation among predators are investigated. The analysis involves the computation of many semi-algebraic systems of large degrees. We apply the pseudo-division reduction, real-root isolation technique and complete discrimination system of polynomial to obtain parameter conditions for the exact number of equilibria and their qualitative properties as well as a complete investigation of bifurcations including saddle-node, transcritical, pitchfork, Hopf and Bogdanov-Takens bifurcations. Moreover, numerical simulations are presented to support our theoretical results.

description: The document is the protocol of a scoping review.
Objective: The objective of this scoping review is to explore and characterize studies using transfer learning for non-image data in clinical research.
Introduction: Transfer learning is the use of a pre-trained model for a task different to what it was originally trained for. The method has garnered considerable attention in recent years, especially in computer vision and natural language processing. However, despite the increasing interest in machine learning among clinical researchers, the use of transfer learning is not well studied in the medical literature, especially for non-image data.
Inclusion criteria: We will include clinical studies, published in English in the medical literature, that used transfer learning (fine-tuning or feature-representation transfer) for the analysis of non-image data (e.g. tabular, time series, text, audio). Studies using synthetic data of these types will also be included if they represent or are based on human participants.
Methods: We will search PubMed, EMBASE and CINAHL for peer-reviewed articles (original articles and brief reports). Each abstract/full-text article will be screened by at least two independent reviewers. Study characteristics will be extracted using a piloted data extraction form. Results will be presented using descriptive statistics and visualizations.

description: Increased price volatility and narrow profit margins in production agriculture underscore the importance of sound record keeping practices. With the ever-changing environment of financial software technology, there is a growing need to educate Texas farmers and ranchers on computerized bookkeeping applications. To equip producers with stronger record-keeping skills, Texas A&M AgriLife Extension Economists developed a two-day short course that teaches basic level QuickBooks® accounting software. The main goal of these workshops is to improve financial record-keeping and analysis capabilities, allowing producers to make more informed management decisions.

description: We consider the interplay of fundamental and matter-induced T violation effects in neutrino oscillations in matter. After discussing the general features of these effects we derive a simple approximate analytic expression for the T-violating probability asymmetry ΔP^T_{ab} for three-flavour neutrino oscillations in a matter with an arbitrary density profile in terms of the two-flavour neutrino amplitudes. Explicit examples are given for the cases of a two-layer medium and for the adiabatic limit in the general case. We then discuss implications of the obtained results for long baseline experiments. We show, in particular, that asymmetric matter effects cannot hinder the determination of the fundamental CP and T-violating phase δ_{CP} in the long baseline experiments as far as the error in this determination is larger than 1% at 99% C.L. Since there are no T-violating effects in the two-flavour case, and in the limits of vanishing θ_{13} or Δm_{21}^2 the three-flavour neutrino oscillations effectively reduce to the two-flavour ones, studying the T-violating asymmetries ΔP^T_{ab} can in principle provide us with a complementary means of measuring θ_{13} and Δm_{21}^2.

Residential Water Demand in China: Applications of Double-Log Model and EDM System

description: This study undertook the residential water demand analysis based on a panel data covered 31 provinces of China during the sample period from 2004 to 2013. Two models are employed in this study: Double-Log model and EDM model. The estimates of double-log model show that the different levels of income cannot impact the water price elasticities significantly but the fixed effects estimator gives a more appropriate estimate for the water demand system. In addition, both the water price and the income are inelastic. However, with the EDM model estimations, the results reveal that the water price is elastic for the residential water demand in the short run, and the partial price-supply elasticity is negative due to estimates of total elasticities. Both two models gave the result that the residential water is an inferior good in China.

description: Best-worst scaling, also called maximum-difference scaling, is used to rank the most important to least important benefits and characteristics of a conservation practice during the adoption decision-making processes of agricultural producers and non-farming/absentee landowners. Both groups are found to rank and value the attributes and reasons for adoption of conservation practices differently at the 95% significance level. Producers rank “practice benefits the farm ecosystem” as the most important consideration when making conservation practice decisions on their operation 29.7% of the time. This is followed closely by the attribute, “practice improves profit,” which is chosen as the best reason by 29.4% of producers. Non-farming/absentee landowners rank, “practice benefits the farm ecosystem” as the most important factor 33.4% of the time, but they choose, “practice improves profit” only 23.4%. This difference, combined with variations in the rankings of the reasons for adopting conservation practices between the two groups reinforces the importance of land tenure in decision making. This indicates the need for both new extension educational efforts and economic incentives to reduce negative externalities from sediment loading and eutrophication that could be ameliorated from increased adoption of soil and water conservation.

Standard Model at Intersecting D5-branes: Lowering the String Scale

description: Recently a class of Type IIA orientifold models was constructed yielding just the fermions of the SM at the intersections of D6-branes wrapping a 6-torus. We generalize that construction to the case of Type IIB compactified on an orientifold of T^4 \times (C/Z_N) with D5-branes intersecting at angles on T^4. We construct explicit models in which the massless fermion spectrum is just the one of a three-generation Standard Model. One of the motivations for these new constructions is that in this case there are 2 dimensions which are transverse to the SM D5-brane configuration. By making those two dimensions large enough one can have a low string scale M_s of order 1-10 TeV and still have a large M_{Planck} in agreement with observations. From this point of view, these are the first explicit D-brane string constructions where one can achieve having just the fermionic spectrum and gauge group of the SM embedded in a Low String Scale scenario. The cancellation of U(1) anomalies turns out to be quite analogous to the toroidal D6-brane case and the proton is automatically stable due to the gauging of baryon number. Unlike the D6-brane case, the present class of models has N = 0 SUSY both in the bulk and on the branes and hence the spectrum is simpler.
