description: Computational fluid dynamics (CFD) models are emerging as tools for assisting in diagnostic assessment of cardiovascular disease. Recent advances in image segmentation has made subject-specific modelling of the cardiovascular system a feasible task, which is particularly important in the case of pulmonary hypertension (PH), which requires a combination of invasive and non-invasive procedures for diagnosis. Uncertainty in image segmentation can easily propagate to CFD model predictions, making uncertainty quantification crucial for subject-specific models. This study quantifies the variability of one-dimensional (1D) CFD predictions by propagating the uncertainty of network geometry and connectivity to blood pressure and flow predictions. We analyse multiple segmentations of an image of an excised mouse lung using different pre-segmentation parameters. A custom algorithm extracts vessel length, vessel radii, and network connectivity for each segmented pulmonary network. We quantify uncertainty in geometric features by constructing probability densities for vessel radius and length, and then sample from these distributions and propagate uncertainties of haemodynamic predictions using a 1D CFD model. Results show that variation in network connectivity is a larger contributor to haemodynamic uncertainty than vessel radius and length.

description: Precision electroweak tests are a powerful probe of physics beyond the Standard Model, but the sensitivity is limited by the precision with which the $W$ boson mass ($M_W$) has been measured. The Parton Distribution Function (PDF) uncertainties are a potential limitation for measurements of $M_W$ with LHC data. It has recently been pointed out that, thanks to LHCb's unique forward rapidity acceptance, a new measurement of $M_W$ by LHCb can improve this situation. Here we report on a detailed study on the mechanism driving the PDF uncertainty in the LHCb measurement of $M_W$, and propose an approach which should reduce this uncertainty by roughly a factor of two using LHCb Run 2 data.

description: A comparison of the rates for psi(2S) -> pi^+ pi^- J/psi, J/psi -> l^+l^- and J/psi -> anything is used to determine the J/psi leptonic branching fractions. The results are B(J/psi -> e^+e^-) = (5.90 +/- 0.05 +/- 0.10)% and B(J/psi -> mu^+ mu^-) = (5.84 +/- 0.06 +/- 0.10)%, where the first error is statistical and the second is systematic. Assuming lepton universality, the leptonic branching fraction of the J/psi is B(J/psi -> l^+ l^-) = (5.87 +/- 0.04 +/- 0.09)% per species. This result is used to estimate the QCD scale factor Lambda_MSbar and the strong coupling constant alpha_s.

IGNITION

description: The acoustic igniters based on Hartmann-Sprenger tube are being developed by Firefly Aerospace Ukraine for several propulsion concepts operating on LOX and Kerosene. The present paper describes the experimental study of such igniters. The stable ignition was confirmed within inlet pressure range from 10 to 120 bar and mixture ratio range from 0.5 to 8. The maximum cumulative firing time of one igniter was over 100 seconds. Such results were obtained through the application of kerosene regenerative cooling and optimization of kerosene injection system. All igniters were 3D printed using a selective laser melting method.

description: We present the most sensitive direct imaging and radial velocity (RV) exploration of $ε$ Eridani to date. $ε$ Eridani is an adolescent planetary system, reminiscent of the early Solar system. It is surrounded by a prominent and complex debris disk which is likely stirred by one or several gas giant exoplanets. The discovery of the RV signature of a giant exoplanet was announced 15 years ago, but has met with scrutiny due to possible confusion with stellar noise. We confirm the planet with a new compilation and analysis of precise RV data spanning 30 years, and combine it with upper limits from our direct imaging search, the most sensitive ever performed. The deep images were taken in the Ms band (4.7$μ$m) with the vortex coronagraph recently installed in W.M. Keck Observatory's infrared camera NIRC2, which opens a sensitive window for planet searches around nearby adolescent systems. The RV data and direct imaging upper limit maps were combined in an innovative joint Bayesian analysis, providing new constraints on the mass and orbital parameters of the elusive planet. $ε$ Eridani b has a mass of $0.78^{+0.38}_{-0.12}$ $M_{Jup}$ and is orbiting $ε$ Eridani at about $3.48\pm 0.02$ AU with a period of $7.37 \pm 0.07$ years. The eccentricity of $ε$ Eridani b's orbit is $0.07^{+0.06}_{-0.05}$, an order of magnitude smaller than early estimates and consistent with a circular orbit. We discuss our findings from the standpoint of planet-disk interactions and prospects for future detection and characterization with the James Webb Space Telescope.

description: The $α$-XY model generalizes, through the introduction of a power-law decaying potential, a well studied mean-field hamiltonian model with attractive long-range interactions. In the $α$-model, the interaction between classical rotators on a lattice is gauged by the exponent $α$ in the couplings decaying as $r^α$, where $r$ are distances between sites. We review and comment here a few recent results on the static and dynamic properties of the $α$-model. We discuss the appropriate $α$ dependent rescalings that map the canonical thermodynamics of the $α$-model into that of the mean field model. We also show that the chaotic properties of the model, studied as a function of $α$ display an universal behaviour.

description: Excerpt: The nature of agriculture's contributions to national economic development has been described in excellent papers by Johnston and Mellor, Ranis and Fei, D. Gale Johnson, Sherman Johnson, Simon Kuznets, Lawrence Witt, and others. Recently, we added to this literature an article on the mechanics of agricultural productivity and economic growth, which shows how improvement in agricultural productivity contributed to national economic growth of an imaginary country called Hypothetica. For this annual meeting assignment we are asked to shed to some light on the extent or magnitude of agriculture’s contributions to economic development of countries in the real world where data required for analysis are not as readily available as they were in the case of Hypothetica. We draw upon findings from an AID research project which identified and measured factors associated with changes in agricultural productivity in underdeveloped countries. But first we need to show how the contribution that the agricultural sector makes to national economic growth depends upon improvement in agricultural productivity.

description: This paper presents a large parameter study on meteorological conditions to investigate the aerodynamic performance degradation of UAVs for a wide range of icing conditions. The knowledge about weather influences is essential for the development of efficient icing protection. The numerical CFD simulations for ice accretion and performance evaluation were performed on the 2D airfoil RG-15, using FENSAPICE. The method is validated with literature and experimental data. The results show a significant deterioration of lift and drag for all selected icing conditions and a distinct dependency of temperature, liquid water content and ice mass on the aerodynamic performance.

The flavor composition of astrophysical neutrinos after 8 years of IceCube: an indication of neutron decay scenario?

Year: 2019

description: In this work we present an updated study of the flavor composition suggested by astrophysical neutrinos observed by IceCube. The main novelties compared to previous studies are the following: 1) we use the most recent measurements, namely 8 years of throughgoing muons and 7.5 years of High Energy Starting Events (HESE); 2) we consider a broken power law spectrum, in order to be consistent with the observations between 30 TeV and few PeV; 3) we use the throughgoing muon flux to predict the number of astrophysical HESE tracks. We show that accounting for the three previous elements, the result favors surprisingly the hypothesis of neutrinos produced by neutron decay, disfavoring the standard picture of neutrinos from pion decay at 2.0$σ$ and the damped muons regime at $2.6 σ$, once the atmospheric background is considered. Although the conventional scenario is not yet completely ruled out in the statistically and alternative interpretations are also plausible, such as an energy spectrum characterized by a non trivial shape, this intriguing result may suggest new directions for both theoretical interpretation and experimental search strategies.

description: Over a remarkably productive professional life Brian Spalding largely shaped the development of numerical procedures for computing complex turbulent flows. He created a major software company, CHAM, through which the fruits of his group's research could be made available to industry and other research groups across the globe. Thus, he became the outstanding founding figure in the subject now called computational fluid dynamics (CFD). His contributions were by no means limited to strategies for converting systems of non-linear partial differential equations to forms suitable for computer solution; he also brought notable innovations to the physical modelling of combustion, turbulence and two-phase flows.Besides research, he engaged deeply with the research community in heat and mass transfer, becoming a founding editor of two international journals in these areas, and a principal driver behind the creation of the International Centre for Heat and Mass Transfer in Belgrade. He also served as the inaugural scientific chairman of the European Research Community on Flow, Turbulence and Combustion. He led a protracted and ultimately successful campaign to enable Veniamin Levich to leave the Soviet Union to settle in Israel. Outside of his technical work, his principal passions were poetry and the Russian language, which were intertwined in several published volumes.

description: In a recent Letter, Kusenko and Segre proposed a new mechanism to explain the observed proper motions of pulsars. Their mechanism was based on the asymmetric neutrino emission induced by neutrino oscillations in the protoneutron star magnetic field. In this note I point out that their estimate of the asymmetry in the neutrino emission is incorrect. A proper calculation shows that their mechanism at least requires a magnetic field of 10**16 G in order to produce the observed average pulsar velocity.

description: Productivity of natural pastures in Iberian dehesas is usually low and very variable (on average 1440 kg dry matter (DM) ha/yr). They also provide low nutritive value forage, containing 4-20% legume fraction, 9-12% crude protein, 44-59% neutral detergent fibre and 28-37% acid detergent fibre. In order to improve the productivity and quality of herbage biomass, and to supplement the natural pasture during shortage periods, farmers have traditionally implemented two practices: the sowing of well-adapted productive pasture species, and/or the sowing of forage crops. In dehesa ecosystems, those fodder crops often play a fundamental role in livestock feeding as a complement to natural pastures, both in productivity and in quality. Triticale, a hybrid of wheat and rye, is now becoming a popular fodder crop on Mediterranean livestock farms.

description: In Ethiopia, the significance of urban agriculture as a source of livelihood is well-recognized. However, the
benefits of urban agriculture have not yet been realized to a satisfying degree. This article aims to understand the drivers, practices, and challenges of urban agriculture in Dilla town. The empirical data upon which the author draws was gathered through repeated periods of qualitative fieldwork carried out in 2020 with 36 farmers in Dilla town, Southern Ethiopia. Direct observation, interviews, and focus group discussions were used to obtain the required empirical data. This study has also benefited from various secondary sources. As the study shows, direct food supply, increased economic security, improved social inclusion, and regulated urban microclimate are the logic behind the involvement of farmers in urban agriculture. Urban agriculture is characterized by mixed-type of farming and includes crop production (mainly horticulture production) and livestock production (mainly poultry and dairy farming). Crop production in the town takes different forms and it includes home-garden farming, open-space farming, and peri-urban farming. As the study further shows, lack of access to urban agricultural land, land tenure insecurity, lack of urban farming skills, lack of access to credit facilities, lack of basic agricultural supplies and extension services, and limited attention given to urban agriculture from relevant state structures are major challenges facing urban agriculture. The policy implication of the study is that the government should work

description: We develop threshold resummation for single-particle inclusive cross sections in hadron-hadron collisions to the level of next-to-next-to-leading logarithm, up to full matching with two-loop hard functions. We define and calculate all one-loop soft functions for all partonic channels. This enables us to separate the hard and soft functions at one loop. Along with these results, the one-loop finite parts of jet functions are used to check that the full soft, collinear and virtual corrections are reproduced to one loop for all partonic reactions. We exhibit these NLO results explicitly. NLO expansions of the resummed cross section match the exact NLO results extremely well numerically, and two loop expansions result in substantial corrections over many kinematic configurations. Explicit results are given in Mellin moment space, and a number of options for generating resummed cross sections are discussed.

The spatial direction of this magnetization introduces complex phases into the Fourier coefficients of the magnetic field. We investigate the effect of the relative phases between electric and magnetic modulation on band width and internal structure of the Landau levels.

description: The effect of shear on the ordering-kinetics of a conserved order-parameter system with O(n) symmetry and order-parameter-dependent mobility Γ({\vecϕ}) \propto (1- {\vecϕ} ^2/n)^αis studied analytically within the large-n limit. In the late stage, the structure factor becomes anisotropic and exhibits multiscaling behavior with characteristic length scales (t^{2α+5}/\ln t)^{1/2(α+2)} in the flow direction and (t/\ln t)^{1/2(α+2)} in directions perpendicular to the flow. As in the α=0 case, the structure factor in the shear-flow plane has two parallel ridges.

description: We use restricted data from the Quarterly Census of Employment and Wages to link the universe of US establishments with the universe of contractors in the Federal Procurement Data System. Leveraging detailed institutional knowledge of federal acquisitions, we construct a new dataset of unanticipated contracts and examine their effects on employment growth. We find positive, significant and persistent effects on firms with fewer than 150 employees. Using loan data from the US Federal Reserve (Y14-Q), we show that small firms expand their credit and receive lower interest rates after winning unanticipated contracts. At the regional level, we estimate a cost-per­job of US$57,000 per year using unanticipated contracts—an order of magnitude lower than previous estimates based on all defense contracts. Lastly, we leverage the restricted census data to decompose the employment multiplier into a direct effect on contractors of 55% and an indirect effect on non­contractors of 45%.
description: Nous raccordons les données à diffusion restreinte sur les établissements américains tirées du Quarterly Census of Employment and Wages (QCEW, soit le recensement trimestriel de l’emploi et des salaires) aux données sur les fournisseurs qui proviennent du Federal Procurement Data System (un système qui recense les données sur les contrats d’approvisionnement du gouvernement fédéral américain). En tirant parti de connaissances institutionnelles détaillées sur les acquisitions fédérales, nous construisons un nouvel ensemble de données sur les contrats imprévus et examinons leurs effets sur la croissance de l’emploi. Nous constatons des effets positifs, significatifs et persistants sur les entreprises de moins de 150 employés. À l’aide des données sur les prêts recueillies par la Réserve fédérale américaine (relevé Y-14Q), nous montrons que les petites entreprises élargissent leur crédit et obtiennent des taux d’intérêt plus bas après avoir remporté des contrats imprévus. Au niveau régional, nous estimons que l’octroi de contrats imprévus entraîne un coût de 57 000 dollars américains par an pour chaque emploi créé, un ordre de grandeur inférieur aux estimations précédentes basées sur tous les contrats attribués dans le secteur de la défense. Enfin, nous exploitons les données à diffusion restreinte du QCEW pour décomposer le multiplicateur de l’emploi en un effet direct de 55 % sur les entreprises à qui un contrat d’approvisionnement est octroyé et un effet indirect de 45 % sur les autres entreprises.

description: We present the results of non-equilibrium molecular dynamics simulations for the growth of a solid binary alloy from its liquid phase. The regime of high pulling velocities, $V$, for which there is a progressive transition from solute segregation to solute trapping, is considered. In the segregation regime, we recover the exponential form of the concentration profile within the liquid phase. Solute trapping is shown to settle in progressively as $V$ is increased and our results are in good agreement with the theoretical predictions of Aziz [J. Appl. Phys. {\bf 53}, 1158 (1981)]. In addition, the fluid advection velocity is shown to remain directly proportional to $V$, even at the highest velocities considered here ($V\simeq10$ms$^{-1}$).

description: ProIO is a new event-oriented streaming data format which utilizes Google's Protocol Buffers (protobuf) to be flexible and highly language-neutral. The ProIO concept is described here along with its software implementations. The performance of the ProIO concept for a dataset with Monte-Carlo event records used in high-energy physics was benchmarked and compared/contrasted with ROOT I/O. Various combinations of general-purpose compression and variable-length integer encoding available in protobuf were used to investigate the relationship between I/O performance and size-on-disk in a few key scenarios.

Temporal clustering of rotational glitches in the Crab pulsar

description: It is an open question whether glitch activity in individual pulsars varies on decadal time-scales. The Crab pulsar has experienced 23 spin-up glitches in the last 36 years, interrupting an otherwise monotonic deceleration. A homogeneous Poisson process, i.e. a process with constant rate, is not sufficient to describe the time-ordered distribution of glitch epochs in the Crab pulsar. There are signs of clustering at the $2σ$ level when testing with Ripley's $K$ function. Two alternative, inhomogeneous models with one and two step-wise rate changes are found to have higher relative evidence (Bayes factors of 1.74 and 2.86 respectively) than the homogeneous Poisson process. The distinction between clustering, where events are correlated, and rate variation is discussed. The implications for glitch microphysics, in particular trigger mechanisms based on avalanche processes, are briefly discussed.

description: We present a comprehensive analysis of a linear growth model, which combines the characteristic features of the Edwards--Wilkinson and noisy Mullins equations. This model can be derived from microscopics and it describes the relaxation and growth of surfaces under conditions where the nonlinearities can be neglected. We calculate in detail the surface width and various correlation functions characterizing the model. In particular, we study the crossover scaling of these functions between the two limits described by the combined equation. Also, we study the effect of colored and conserved noise on the growth exponents, and the effect of different initial conditions. The contribution of a rough substrate to the surface width is shown to decay universally as $w_i(0) (ξ_s/ξ(t))^{d/2}$, where $ξ(t) \sim t^{1/z}$ is the time--dependent correlation length associated with the growth process, $w_i(0)$ is the initial roughness and $ξ_s$ the correlation length of the substrate roughness, and $d$ is the surface dimensionality. As a second application, we compute the large distance asymptotics of the height correlation function and show that it differs qualitatively from the functional forms commonly used in the intepretation of scattering experiments.

Thermal Phases of the Neutral Atomic Interstellar Medium -- from Solar Metallicity to Primordial Gas

description: We study the thermal structure of the neutral atomic (H {\small I}) interstellar medium across a wide range of metallicities, from supersolar down to vanishing metallicity, and for varying UV intensities and cosmic-ray ionization rates. We calculate self-consistently the gas temperature and species abundances (with a special focus on the residual H$_2$), assuming thermal and chemical steady-state. For solar metallicity, $Z' \equiv 1$, we recover the known result that there exists a pressure range over which the gas is multiphased, with the warm ($\sim 10^4$ K, WNM) and cold ($\sim 100$ K, CNM) phases coexisting at the same pressure. At a metallicity $Z' \approx 0.1$, the CNM is colder (compared to $Z'=1$) due to the reduced efficiency of photoelectric heating. For $Z' \lesssim 0.1$, cosmic-ray ionization becomes the dominant heating mechanism and the WNM-to-CNM transition shifts to ever increasing pressure/density as the metallicity is reduced. For metallicities $Z' \lesssim 0.01$, H$_2$ cooling becomes important, lowering the temperature of the WNM (down to $\approx 600$ K), and smoothing out the multiphase phenomenon. At vanishing metallicities, H$_2$ heating becomes effective and the multiphase phenomenon disappears entirely. We derive analytic expressions for the critical densities for the warm-to-cold phase transition in the different regimes, and the critical metallicities for H$_2$ cooling and heating. We discuss potential implications on the star-formation rates of galaxies and self-regulation theories.

description: We investigate theoretically the properties of a trapped gas of fermionic atoms in both the normal and the superfluid phases. Our analysis, which accounts for the shell structure of the normal phase spectrum, identifies two observables which are sensitive to the presence of the superfluid: the response of the gas to a modulation of the trapping frequency, and the heat capacity. Our results are discussed in the context of experiments on trapped Fermi gases.
