description: Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using Gaia Data Release 2 by Berger et al. (2020), we re-compute Kepler planet radii and incident fluxes and investigate their distributions with stellar mass and age. We measure the stellar mass dependence of the planet radius valley to be $d \log R_{\mathrm{p}}$/$d \log M_\star = 0.26^{+0.21}_{-0.16}$, consistent with the slope predicted by a planet mass dependence on stellar mass ($0.24-0.35$) and core-powered mass-loss (0.33). We also find first evidence of a stellar age dependence of the planet populations straddling the radius valley. Specifically, we determine that the fraction of super-Earths ($1-1.8 \mathrm{R_\oplus}$) to sub-Neptunes ($1.8-3.5 \mathrm{R_\oplus}$) increases from $0.61 \pm 0.09$ at young ages (< 1 Gyr) to $1.00 \pm 0.10$ at old ages (> 1 Gyr), consistent with the prediction by core-powered mass-loss that the mechanism shaping the radius valley operates over Gyr timescales. Additionally, we find a tentative decrease in the radii of relatively cool ($F_{\mathrm{p}} < 150 \mathrm{F_\oplus}$) sub-Neptunes over Gyr timescales, which suggests that these planets may possess H/He envelopes instead of higher mean molecular weight atmospheres. We confirm the existence of planets within the hot sub-Neptunian "desert" ($2.2 < R_{\mathrm{p}} < 3.8 \mathrm{R_\oplus}$, $F_{\mathrm{p}} > 650 \mathrm{F_\oplus}$) and show that these planets are preferentially orbiting more evolved stars compared to other planets at similar incident fluxes. In addition, we identify candidates for cool ($F_{\mathrm{p}} < 20 \mathrm{F_\oplus}$) inflated Jupiters, present a revised list of habitable zone candidates, and find that the ages of single- and multiple-transiting planet systems are statistically indistinguishable.

description: In this paper we solve numerically the two dimensional elliptic sine-Gordon equation with appropriate boundary conditions. These boundary conditions are chosen to correspond to the Josephson interaction between two adjacent pancakes belonging to the same flux-line in a highly anisotropic superconductor. An extrapolation is obtained between the regimes of low and high separation of the pancakes. The resulting formula is a better candidate for use in numerical simulations than previously derived formulas.

description: We study the nonequilibrium phase transition in a contact process with extended quenched defects by means of Monte-Carlo simulations. We find that the spatial disorder correlations dramatically increase the effects of the impurities. As a result, the sharp phase transition is completely destroyed by smearing. This is caused by effects similar to but stronger than the usual Griffiths phenomena, viz., rare strongly coupled spatial regions can undergo the phase transition independently from the bulk system. We determine both the stationary density in the vicinity of the smeared transition and its time evolution, and we compare the simulation results to a recent theory based on extremal statistics.

A Magnetar-Asteroid Impact Model for FRB 200428 Associated with an X-ray Burst from SGR 1935+2154
Creators: name: Dai, Z. G.
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Very recently, an extremely bright fast radio burst (FRB) 200428 with two sub-millisecond pulses was discovered to come from the direction of the Galactic magnetar SGR 1935+2154, and an X-ray burst (XRB) counterpart was detected simultaneously. These observations favor magnetar-based interior-driven models. In this Letter, we propose a different model for FRB 200428 associated with an XRB from SGR 1935+2154, in which a magnetar with high proper velocity encounters an asteroid of mass $\sim10^{20}\,$g. This infalling asteroid in the stellar gravitational field is first possibly disrupted tidally into a great number of fragments at radius $\sim {\rm a\,\,few}$ times $10^{10}\,$cm, and then slowed around the Alfv$\acute{\rm e}$n radius by an ultra-strong magnetic field and in the meantime two major fragments of mass $\sim 10^{17}\,$g that cross magnetic field lines produce two pulses of FRB 200428. The whole asteroid is eventually accreted onto the poles along magnetic field lines, impacting the stellar surface, creating a photon-e$^\pm$ pair fireball trapped initially in the stellar magnetosphere, and further leading to an XRB. We show that this gravitationally-powered model can interpret all of the observed features self-consistently.

description: The paper presents the productivity size and structure of agricultural farms with regard to the production trend. The aim was achieved based on the research carried out in 80 farms of the Southern Poland. Objects for research were divided into 4 groups: one-trend farms – aiming at plant and animal production, two-trend and mixed farms. It was explicitly proved that productivity of farms from the analyzed region depends on the production trend. The highest value of commodity production was reported in one-trend farms – plant production – 27,242 PLN/ha and was over 39 times higher than in case of one-trend objects – animal production (696.3 PLN/ha).

description: In Poland, in the year 2010 compared to 2002 increased both the number of tractors (about 7%), and the number of tractors per 100 hectares of agricultural land (about 17%), but decreased about 15% of the agricultural area per one tractor. The specificity of the Polish agriculture indicates, that equipping agriculture with tractors was and is regionally diverse. The aim of the study was to assess the status and trends of changes in equipping farms in Poland with tractors in spatial terms. There was used method of vectors’ elimination to divide provinces into subsets, that are characterized by a relatively low degree of differentiation of structure of the number of tractors in agriculture by area groups of agricultural land. The estimated coefficients of concentration allowed to assess uniformity of distribution of phenomenon by type.

description: On a lattice with 2+1-flavor dynamical domain-wall fermions at the physical pion mass, we calculate the decay constants of $D_{s}^{(*)}$, $D^{(*)}$ and $ϕ$. The lattice size is $48^3\times96$, which corresponds to a spatial extension of $\sim5.5$ fm with the lattice spacing $a\approx 0.114$ fm. For the valence light, strange and charm quarks, we use overlap fermions at several mass points close to their physical values. Our results at the physical point are $f_D=213(5)$ MeV, $f_{D_s}=249(7)$ MeV, $f_{D^*}=234(6)$ MeV, $f_{D_s^*}=274(7)$ MeV, and $f_ϕ=241(9)$ MeV. The couplings of $D^*$ and $D_s^*$ to the tensor current ($f_V^T$) can be derived, respectively, from the ratios $f_{D^*}^T/f_{D^*}=0.91(4)$ and $f_{D_s^*}^T/f_{D_s^*}=0.92(4)$, which are the first lattice QCD results. We also obtain the ratios $f_{D^*}/f_D=1.10(3)$ and $f_{D_s^*}/f_{D_s}=1.10(4)$, which reflect the size of heavy quark symmetry breaking in charmed mesons. The ratios $f_{D_s}/f_{D}=1.16(3)$ and $f_{D_s^*}/f_{D^*}=1.17(3)$ can be taken as a measure of SU(3) flavor symmetry breaking.

description: Nutritional and sensory qualities and price are now a very important factor in the demand for the product, especially in situations of considerable overproduction and competition between manufacturers. The aim of this study was to evaluate the sensory quality of sausages Podwawelska in relation to price as an indicator of quality. Material consisted of a sample of sausage Podwawelska derived from 6 manufacturers. To determine the sensory quality scaling method was used, also made the assessment of the overall quality (SOJS). Evaluated the sensory quality of sausages Podwawelskich coming from 6 different manufacturers showed considerable variation. A significant correlation between overall sensory quality of studied sausages and their price was obtained. In the case of sausage found the cheapest worst sensory quality was found. In the case of sausages, the quality of sensory rated positively, the price was adequate to their sensory quality. It has been shown that the price can be an indicator of sensory quality in 50%.

description: We present comprehensive and reliable statistics of high altitude wind speeds and the tropospheric flows at the location of five important astronomical observatories. Statistical analysis exclusively of high altitude winds point to La Palma as the most suitable site for adaptive optics, with a mean value of 22.13 m/s at the 200 mbar pressure level. La Silla is at the bottom of the ranking, with the largest average value 200 mbar wind speed(33.35 m/s). We have found a clear annual periodicity of high altitude winds for the five sites in study. We have also explored the connection of high to low altitude atmospheric winds as a first approach of the linear relationship between the average velocity of the turbulence and high altitude winds (Sarazin & Tokovinin 2001). We may conclude that high and low altitude winds show good linear relationships at the five selected sites. The highest correlation coefficients correspond to Paranal and San Pedro Martir, while La Palma and La Silla show similar high to low altitude wind connection. Mauna Kea shows the smallest degree of correlation, which suggests a weaker linear relationship. Our results support the idea of high altitude winds as a parameter for rank astronomical sites in terms of their suitability for adaptive optics, although we have no evidence for adopting the same linear coefficient at different sites. The final value of this linear coefficient at a particular site could drastically change the interpretation of high altitude wind speeds as a direct parameter for site characterization.

The thermal Casimir effect in lipid bilayer tubules

description: We calculate the thermal Casimir effect for a dielectric tube of radius $R$ and thickness delta formed from a membrane in water. The method uses a field-theoretic approach in the grand canonical ensemble. The leading contribution to the Casimir free energy behaves as -k_BTL kappa_C/R giving rise to an attractive force which tends to contract the tube. We find that kappa_C ~ 0.3 for the case of typical lipid membrane t-tubules. We conclude that except in the case of a very soft membrane this force is insufficient to stabilize such tubes against the bending stress which tends to increase the radius.

description: We report the doping effects of cobalt on van der Waals (vdW) magnet Fe$_5$GeTe$_2$. A series of (Fe$_{1-x}$Co$_x$)$_5$GeTe$_2$ (0$\leq$x$\leq$0.44) single crystals have been successfully grown, their structural, magnetic and transport properties are investigated. For x=0.20, The Curie temperature $T_C$ increases from 276~K to 337~K. Moreover, the magnetic easy-axis is reoriented to the $ab$-plane from the $c$-axis in undoped Fe$_5$GeTe$_2$ with largely enhanced magnetic anisotropy. These magnetic properties would make (Fe$_{0.8}$Co$_{0.2}$)$_5$GeTe$_2$ more effective in stabilizing magnetic order in the two-dimensional limit. A complex magnetic phase diagram is identified on the higher doping side. The x=0.44 crystal first orders ferromagnetically at $T_C$=363~K then undergoes an antiferromagnetic transition at $T_N$=335~K. Furthermore magnetic-field-induced spin-flop transitions are observed for the AFM ground state. Our work reveals (Fe$_{1-x}$Co$_x$)$_5$GeTe$_2$ as promising candidates for developing new spin-related applications and proposes a method to engineer the magnetic properties of vdW magnet.

Magnetospheric Radio Emission from Extrasolar Giant Planets: The Role of the Host Stars

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a new analysis of the expected magnetospheric radio emission from extrasolar giant planets for a distance limited sample of the nearest known extrasolar planets. Using recent results on the correlation between stellar X-ray flux and mass-loss rates from nearby stars, we estimate the expected mass-loss rates of the host stars of extrasolar planets that lie within 20pc of the Earth. We find that some of the host stars have mass-loss rates that are more than 100 times that of the Sun, and given the expected dependence of the planetary magnetospheric radio flux on stellar wind properties this has a very substantial effect. Using these results and extrapolations of the likely magnetic properties of the extrasolar planets we infer their likely radio properties. We compile a list of the most promising radio targets, and conclude that the planets orbiting Tau Bootes, Gliese 86, Upsilon Andromeda and HD1237 (as well as HD179949) are the most promising candidates, with expected flux levels that should be detectable in the near future with upcoming telescope arrays. The expected emission peak from these candidate radio emitting planets is typically \~40-50 MHz. We also discuss a range of observational considerations for detecting extrasolar giant planets.

description: The Relationship Coffee Model (RCM) is an emerging business model in the coffee value chain that promotes long-term partnerships between coffee buyers and smallholder growers based on transparency, product quality and value sharing. However, to date, there are limited studies assessing outcomes for the smallholder growers participating in high-quality coffee value chains and specifically in models such as RCM. We developed a framework to examine how geography, environmental conditions, production practices and technology affect coffee quality, and consequently, grower’s ability to participate in RCM. In turn, we evaluated the impact of RCM participation on key environmental, socio-economic, and technological indicators. Using data collected from 265 Colombian smallholder growers, we examined relationships among socio-economic characteristics, soil quality indicators, coffee landscape characteristics, bird populations, and product quality scores. Our estimation based on propensity score matching indicated that RCM participants employ more environmentally-friendly resource management practices, have better understanding of the coffee business and are more optimistic about the future of the industry, relative to non-participants. Although farm gate prices did not significantly differ between the two groups, RCM participants had increased access to credit. Overall, the estimated impacts suggest that RCM contributes to integrate smallholder growers into global-coffee markets and generates socioenvironmental benefits.

description: Complex organic molecules have previously been discovered in solar type protostars, raising the questions of where and how they form in the envelope. Possible formation mechanisms include grain mantle evaporation, interaction of the outflow with its surroundings or the impact of UV/X-rays inside the cavities. In this Letter we present the first interferometric observations of two complex molecules, CH3CN and HCOOCH3, towards the solar type protostar IRAS16293-2422. The images show that the emission originates from two compact regions centered on the two components of the binary system. We discuss how these results favor the grain mantle evaporation scenario and we investigate the implications of these observations for the chemical composition and physical and dynamical state of the two components.

description: We develop a light-matter interface enabling strong and uniform coupling between a chain of cold atoms and photons of an optical cavity. This interface is a fiber Fabry-Perot cavity, doubly resonant for both the wavelength of the atomic transition and for a geometrically commensurate red-detuned intracavity trapping lattice. Fulfilling the condition of a strong and uniform atom-photon coupling requires optimization of the spatial overlap between the two standing waves in the cavity. In a strong-coupling cavity, where the mode waists and Rayleigh range are small, we derive the expression of the optimal trapping wavelength taking into account the Gouy phase. The main parameter controlling the overlap of the standing waves is the relative phase shift at the reflection on the cavity mirrors between the two wavelengths, for which we derive the optimal value. We have built a microcavity optimized according to these results, employing custom-made mirrors with engineered reflection phase for both wavelengths. We present a method to measure with high precision the relative phase shift at reflection, which allows us to determine the spatial overlap of the two modes in this cavity.

Fluxes of energy and carbon dioxide over a suburban area of Vancouver, BC
Creators: name: Walsh, Cindy Jennifer
Publisher: name: University of British Columbia
Year: 2010

description: In this study, a relatively long-term (August 2001 - December 2002) measurement campaign o f radiation, energy and atmospheric CO₂ fluxes was conducted in a fairly homogeneous suburb of Vancouver, British Columbia (Sunset site). Examination of radiative flux densities revealed that the incoming and outgoing short and longwave radiation followed expected patterns throughout the year, and at the diurnal time scale. Energy fluxes demonstrated more complex patterns. Sensible heat dominated throughout the year. Latent heat was lower than expected. The reasons for this are difficult to determine with confidence but are thought to be at least partially related to low data coverage during the winter. The Sunset site has also become more built over the years with natural surfaces transformed into impervious surfaces that more readily accept heat. The role of heat storage played an important role in the energy balance at the diurnal time scale. The annual pattern of CO₂ followed expected seasonal trends, with the lowest concentrations recorded in the summer corresponding to the peak in photosynthesis. Diurnal trends of CO₂ concentrations appear to be at least partly linked to the pattern of fossil fuel consumption. A characteristic peak in concentrations at the diurnal time scale was seen in the morning that coincided with the morning rush hour. The pattern of CO₂ fluxes proved more difficult to interpret. Examination of annual CO₂ flux patterns revealed few negative fluxes indicating that the site was a source for CO₂ for most of the year. The diurnal pattern of CO₂ fluxes closely resembled patterns observed in other urban areas, but of particular interest at the Sunset site was an apparent relationship between wind direction and flux strength. Throughout the year, when the wind was coming from the direction of a nearby busy intersection, fluxes were higher than when the wind was coming from all other directions. This indicates that fluxes may not be well mixed at the sensor height. This directional bias was not observed in the fluxes of heat or water vapour indicating that there may be significant spatial differences in the sources of CO₂ and/or an inequality in the transfer efficiencies of different entities.
title: A National Literacy Strategy For All: How Can We Ensure That The Literacy Classroom Meets The Needs Of Every Child?
Creators: name: Watkinson, Maureen
Publisher: name: The Open University
Year: 2001

description: This thesis sets out to investigate the issues surrounding the National Literacy Strategy within the inclusive classroom. In order to set the study within a context it was necessary to examine the development of the English National Curriculum that led to the strategy’s introduction into Primary Schools in England during 1998. In my role of Literacy Consultant I supported schools on the introduction of the NLS. One of these schools, which I shall call Northtown School, had been placed in ‘Special Measures’ following an inspection by Her Majesty’s Inspectors and this added another dimension to the research which surrounded a participant action research study within one classroom of the school. So called ‘failing’ schools only exist when they are identified by such inspections and I put forward a case against the criteria by which they are assessed. The issues surrounding an inclusive classroom are central to my theme and I put forward a criticism of the National Literacy Strategy in its failure to address the speaking and listening skills with the authority necessary to ensure the needs of all children can be met. A Framework for Teaching sets out how teachers are to implement the National Literacy Strategy. The Framework is in essence hierarchical in nature and criterion reference, so seems to be at odds with the notion of a child-centred curriculum. The analysis of the substantial data gathered at each cycle is crucial. The thesis attempts to consider any analysis from multiple perspectives, coming to a conclusion that although we cannot be certain that we have considered every aspect, for we may not have the necessary skills or knowledge, children’s difficulties occur at the interface between them and the classroom curriculum. Solutions are not found ‘within’ the children but at the child/curriculum interface.

description: Light-cone gauge manifestly supersymmetric formulation of eleven dimensional supergravity is developed. The formulation is given entirely in terms of light cone scalar superfield, allowing us to treat all component fields on an equal footing. All higher derivative on mass shell manifestly supersymmetric 4-point functions invariant with respect to linear supersymmetry transformations and corresponding (in gravitational bosonic sector) to terms constructed from four Riemann tensors and derivatives are found. Superspace representation for 4-point scattering amplitudes is also obtained. Superfield representation of linearized interaction vertex of superparticle and supergravity fields is presented. All 4-point higher derivative interaction vertices of ten-dimensional supersymmetric Yang-Mills theory are also determined.

description: We present a method which enables solid-state density functional theory calculations to be applied to systems of almost unlimited size. Computations of physical effects up to the micron length scale but which nevertheless depend on the microscopic details of the electronic structure, are made possible. Our approach is based on a generalization of the Bloch state which involves an additional sum over a finer grid in reciprocal space around each ${\bf k}$-point. We show that this allows for modulations in the density and magnetization of arbitrary length on top of a lattice-periodic solution. Based on this, we derive a set of ultra long-range Kohn-Sham equations. We demonstrate our method with a sample calculation of bulk LiF subjected to an arbitrary external potential containing nearly 3500 atoms. We also confirm the accuracy of the method by comparing the spin density wave state of bcc Cr against a direct supercell calculation starting from a random magnetization density. Furthermore, the spin spiral state of $γ$-Fe is correctly reproduced and the screening by the density of a saw-tooth potential over 20 unit cells of silicon is verified.

description: In this work we show that the gravitational Chern-Simons term, aside from being a key ingredient in inflationary baryogenesis, modifies super-horizon gravitational waves produced during inflation. We compute the super-Hubble gravitational power spectrum in the slow-roll approximation and show that its overall amplitude is modified while its spectral index remains unchanged (at leading order in the slow-roll parameters). Then, we calculate the correction to the tensor to scalar ratio, T/S. We find a correction of T/S which is dependent on $\cal{N}$ (more precisely quadratic in ${\cal N}$), the parameter characterizing the amplitude of the Chern-Simons terms. In a stringy embedding of the leptogenesis mechanism, $\cal{N}$ is the ratio between the Planck scale and the fundamental string scale. Thus, in principle, we provide a direct probe of leptogenesis due to stringy dynamics in the Cosmic Microwave Background (CMB). However, we demonstrate that the corresponding correction of T/S is in fact very small and not observable in the regime where our calculations are valid. To obtain a sizable effect, we argue that a non-linear calculation is necessary.

Sampling mobility profiles of confined fluids with equilibrium molecular dynamics simulations

description: We show how to evaluate mobility profiles, characterizing the transport of confined fluids under a perturbation, from equilibrium molecular simulations. The correlation functions derived with the Green-Kubo formalism are difficult to sample accurately and we consider two complementary strategies: improving the spacial sampling thanks to a new estimator of the local fluxes involving the forces acting on the particles in addition to their positions and velocities, and improving temporal sampling thanks to the Einstein-Helfand approach instead of the Green-Kubo one. We illustrate this method on the case of a binary mixture confined between parallel walls, under a pressure or chemical potential gradient. All equilibrium methods are compared to standard non-equilibrium molecular dynamics (NEMD) and provide the correct mobility profiles. We recover quantitatively fluid viscosity and diffusio-osmostic mobility in the bulk part of the pore. Interestingly, the matrix of mobility profiles for local fluxes is not symmetric, unlike the Onsager matrix for the total fluxes. Even the most computationally efficient equilibrium method (Einstein-Helfand combined with the force-based estimator) remains less efficient than NEMD to determine a single mobility profile. However, the equilibrium approach provides all responses to all perturbations simultaneously, whereas NEMD requires the simulation of several types of perturbations to determine the various responses, each with different magnitudes to check the validity of the linear regime. While NEMD seems more competitive for the present example, the balance should be different for more complex systems, in particular for electrolyte solutions for the responses to pressure, salt concentration and electric potential gradients.

description: We discuss applications of the perturbative QCD approach in the exclusive non-leptonic two body B-meson decays. We briefly review its ingredients and some important theoretical issues on the factorization approaches. PQCD results are compatible with present experimantal data for the charmless B-meson decays. We predict the possibility of large direct CP asymmetry in $B^0 \to π^{+}π^{-}$ $(23\pm7 %)$ and $B^0\to K^{+}π^{-}$ $(-17\pm5%)$. We also investigate the Branching ratios, CP asymmetry and isopsin symmetry breaking in radiative $B \to (K^*/ρ) γ$ decays.

Abundances and Depletions of Interstellar Oxygen

description: We report on the abundance of interstellar neutral oxygen (OI) for 26 sightlines, using data from the Far Ultraviolet Spectroscopic Explorer (FUSE), the International Spectroscopic Explorer (IUE), and the Hubble Space Telescope (HST). OI column densities are derived by measuring the equivalent widths of several ultraviolet absorption lines, and subsequently fitting those to a curve of growth. We consider both our general sample of 26 sightlines and a more restrictive sample of 10 sightlines that utilize HST data for a measurement of the weak 1355 angstrom line of oxygen, and are thus better constrained due to our sampling of all three sections of the curve of growth. The column densities of our HST sample show ratios of O/H that agree with the current best solar value if dust is considered, with the possible exception of one sightline (HD 37903). We note some very limited evidence in the HST sample for trends of increasing depletion with respect to the ratio of total to selective extinction and the molecular fraction of hydrogen, but the trends are not conclusive. Unlike a recent result from Cartledge et al. (2004), we do not see evidence for increasing depletion with respect to the average volume density of hydrogen, but our HST sample contains only two points more dense than the critical density determined in that paper. The column densities of our more general sample show some scatter in O/H, but most agree with the solar value to within errors. We discuss these results in the context of establishing the best method for determining interstellar abundances, the unresolved question of the best value for O/H in the interstellar medium (ISM), the O/H ratios observed in Galactic stars, and the depletion of gas-phase oxygen onto dust grains.
