Template fitting and the large-angle CMB anomalies

description: We investigate two possible explanations for the large-angle anomalies in the Cosmic Microwave Background (CMB): an intrinsically anisotropic model and an inhomogeneous model. We take as an example of the former a Bianchi model (which leaves a spiral pattern in the sky) and of the latter a background model that already contains a non-linear long-wavelength plane wave (leaving a stripy pattern in the sky). We make use of an adaptation of the ``template'' formalism, previously designed to detect galactic foregrounds, to recognize these patterns and produce confidence levels for their detection. The ``corrected'' maps, from which these patterns have been removed, are free of anomalies, in particular their quadrupole and octupole are not planar and their intensities not low. We stress that although the ``template'' detections are not found to be statistically significant they do correct statistically significant anomalies.

 This species is known from Argentina, Uruguay, Paraguay and southern Brazil (Hurd, 1978; Moure, 2007). In Brazil, it has been recorded from the states of Paraná, Santa Catarina and Rio Grande do Sul (Silveira et al., 2002; Moure, 2007). Here it is newly recorded from the state of Minas Gerais. Females were collected, while foraging on flowers, during a brief survey of the bee fauna of the Serra da Canastra National Park, situated in a highland plateau in southwestern Minas Gerais. This represents the northernmost record for the species.

description: It was found from data in the Agricultural Census reports of 1976, 1981 and 1988 that the distribution of the amount of farm workers per hectare differs between statistical regions as defined by the Sentral Statistical Service. Cross-sectional functions were fitted to explain the differences. The following factors yielded the highest contributions: gross income, debt burden per hectare, compensation of workers, quality of resources and the amount of tractors in the region. The goverment's policy regarding interest rates, marketing and general aid has a significant influence on the mobility (demand and supply) of farm workers. Changes in Goverment aid to farmers may thus activate shifts of workers within and out of ariculture. The supply of farm workers is inelastic. This may be ascribed to the former act on influx control, low interest rates which caused labour substitution and the accompanying low compensation of farm workers. Labour is utilised suboptimally while unemployment is on the order of the day. Minimum wages are advocated by various circles as means to rectify the situation. Minimum wages may however lead to more capital/labour substitution and associated unemployment. Subsidisation of farm labour over a medium term should have a positive influence on employment. The subsidy should be phased out as employment approaches optimality.

description: Escalating observations of exo-minor planets and their destroyed remnants both passing through the solar system and within white dwarf planetary systems motivate an understanding of the orbital history and fate of exo-Kuiper belts and planetesimal discs. Here we explore how the structure of a 40-1000 au annulus of planetesimals orbiting inside of a solar system analogue that is itself initially embedded within a stellar cluster environment varies as the star evolves through all of its stellar phases. We attempt this computationally challenging link in four parts: (1) by performing stellar cluster simulations lasting 100 Myr, (2) by making assumptions about the subsequent quiescent 11 Gyr main-sequence evolution, (3) by performing simulations throughout the giant branch phases of evolution, and (4) by making assumptions about the belt's evolution during the white dwarf phase. Throughout these stages, we estimate the planetesimals' gravitational responses to analogues of the four solar system giant planets, as well as to collisional grinding, Galactic tides, stellar flybys, and stellar radiation. We find that the imprint of stellar cluster dynamics on the architecture of $\gtrsim 100$ km-sized exo-Kuiper belt planetesimals is retained throughout all phases of stellar evolution unless violent gravitational instabilities are triggered either (1) amongst the giant planets, or (2) due to a close ($\ll 10^3$ au) stellar flyby. In the absence of these instabilities, these minor planets simply double their semimajor axis while retaining their primordial post-cluster eccentricity and inclination distributions, with implications for the free-floating planetesimal population and metal-polluted white dwarfs.

description: This paper discusses research topics relevant to South African agriculture. Although the developing and commercial sectors are treated separately, the object is to identify issues that policy-makers are likely to address and which will influence the common goals of efficiency and equity. In the developing sector, emphasis is placed on land markets and structural programmes. In the commercial sector, emphasis is placed on land redistribution, inflation and exchange rates, and marketing and labour legislation. Protection of the environment is stressed in both cases.

description: We study the decays of $τ^- \to ν_τ P^-γ(P=π^-, K^-)$ in the light front quark model. We calculate the form factors and use them to evaluate the decay widths. We find that, in the standard model, the decay widths are $1.62\times 10^{-2} (3.86\times10^{-3}) Γ_{τ^- \to ν_τ π^-}$ and $1.91\times 10^{-3} (5.38\times 10^{-4}) Γ_{τ^- \to ν_τ K^-}$ with the cuts of $E_γ=50 (400)$ MeV and $t_{0}=800 (1200)$ MeV for $τ^- \to ν_τ π^- γ$ and $τ^- \to ν_τ K^- γ$, respectively. We also show that with including the radiative decay widths, the experimental rate for $τ^-\to ν_τP^-$ can be explained.

description: Data from 100 commercial farmers in the Aberfeldy pedosystem (situated in the north-eastern Orange Free State, Republic of South Africa) were used to calculate suggested economic and perception criteria for each entrepreneur and to compare this data with actual success rates estimated individually for each case a decade later in 1991. Existing economics of scale means that optimal farm size is not the same for any two managers; the better the manager, the larger the optimum farm size. Furthermore, this commercial dryland study showed that better managers are more effective land users. Better managers farm bigger areas, have lower fixed improvements per hectare, higher income per hectare (both gross and net) and are more realistic in decision making, both with regard to financial goals as well as problem consciousness. The above has important implications for structural adjustment of South African agriculture and offers distinct possibilities when potential success ratings have to be estimated by financial and other institutions.

description: Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars between the K (2.0 - 2.4 μm) and L (3.4 - 4.1 μm) bands. Aiming at an explanation of these findings, we chose the objects αOrionis (Betelgeuse), SW Virginis, and R Leonis, which are of different spectral types and stages of evolution, and which are surrounded by circumstellar envelopes with different optical thicknesses. For these stars, we compared observations with spherically symmetric dust shell models. Photometric and 11 μm interferometric data were also taken into account to further constrain the models. -- [...] -- We conclude that AGB models comprising a photosphere and dust shell, although consistent with SED data and also interferometric data in K and at 11 μm, cannot explain the visibility data in L; an additional source of model opacity, possibly related to a gas component, is needed in L to be consistent with the visibility data.

description: Relativistic heavy-ion collisions create hot quark-gluon plasma as well as very strong electromagnetic (EM) and fluid vortical fields. The strong EM field and vorticity can induce intriguing macroscopic quantum phenomena such as chiral magnetic, chiral separation, chiral electric separation, and chiral vortical effects as well as the spin polarization of hadrons. These phenomena provide us with experimentally feasible means to study the nontrivial topological sector of quantum chromodynamics, the possible parity violation of strong interaction at high temperature, and the subatomic spintronics of quark-gluon plasma. These studies, both in theory and in experiments, are strongly connected with other subfields of physics such as condensed matter physics, astrophysics, and cold atomic physics, and thus form an emerging interdisciplinary research area. We give an introduction to the aforementioned phenomena induced by the EM field and vorticity and an overview of the current status of their experimental research in heavy-ion collisions. We also briefly discuss spin hydrodynamics as well as chiral and spin kinetic theories.

Expenditure patterns of households participating in the Farmer Support Programme of DBSA were analysed and compared with no-participants in two areas, Lebowa and Venda. It is evident from the results of this study that a high proportion of rural households in Lebowa and Venda food insecured. Results also show that the provision of support services to subsistence farmers will help alleviate food insecurity.

description: Verifying that sub-mm galaxies (SMGs) are gravitationally lensed requires time-expensive observations with over-subscribed high-resolution observatories. Here, we aim to strengthen the evidence of gravitational lensing within the Herschel Bright Sources (HerBS) by cross-comparing their positions to optical (SDSS) and near-infrared (VIKING) surveys, in order to search for the foreground lensing galaxy candidates. Resolved observations of the brightest HerBS sources have already shown that most are lensed, and a galaxy evolution model predicts that $\sim$76% of the total HerBS sources are lensed, although with the SDSS survey we are only able to identify the likely foreground lenses for 25% of the sources. With the near-infrared VIKING survey, however, we are able to identify the likely foreground lenses for 57% of the sources, and we estimate that 82% of the HerBS sources have lenses on the VIKING images even if we cannot identify the lens in every case. We find that the angular offsets between lens and Herschel source are larger than that expected if the lensing is done by individual galaxies. We also find that the fraction of HerBS sources that are lensed falls with decreasing 500-micron flux density, which is expected from the galaxy evolution model. Finally, we apply our statistical VIKING cross-identification to the entire Herschel-ATLAS catalogue, where we also find that the number of lensed sources falls with decreasing 500-micron flux density.

A Wind-Driven Model: Application to Peculiar Transients AT2018cow and iPTF14hls

description: We propose a wind-driven model for peculiar transients, and apply the model to AT2018cow and iPTF14hls. In the wind-driven model, we assume that a continuous outflow like a stellar wind is injected from a central system. While these transients have different observational properties, this model can explain their photometric properties which are not reproduced by a supernova-like instantaneous explosion. Furthermore, the model predicts characteristic spectral features and evolution, which are well in line with those of AT2018cow and iPTF14hls. Despite the different observational properties, the wind model shows that they have some common features; the large mass-loss rates (up to $\sim 20M_{\odot}{\rm ~yr^{-1}}$ for AT2018cow and $\sim 75M_{\odot}{\rm ~yr^{-1}}$ for iPTF14hls), and the characteristic radii of $\sim 10^{13}{\rm ~cm}$ for the launch of the wind. It would indicate that both may be related to events involving a red super giant (RSG), in which the RSG envelope is rapidly ejected by an event at a stellar core scale. On the other hand, the main differences are the kinetic energies, the total ejected mass, and time scales. We then suggest that iPTF14hls may represent a dynamical common-envelope evolution induced by a massive binary system ($\sim 120M_{\odot}+100M_{\odot}$). AT2018cow may be either a tidal disruption event of a low-mass RSG by a black hole (BH), or a BH-forming failed supernova.

description: The concept of the Farmer Support Programme (FSP) is one of serving and supporting all small farmers, including part time farmers, so that they can be more efficient in competing in agricultural resource markets and gain better control over their own destiny. Using the preliminary results from the DBSA's evaluation reports of the FSP's in Venda, Lebowa, KaNgwane and Kwazulu, this paper shows the possible effects the FSP strategy have of farmers farming on small farm size of between 1 and four hectares. This is done by comparing farmers using the FSP services and those who do not. The paper concludes that the FSP strategy has positive effects on farmers operating on small areas of 1 hectare or less, but these effects can be increased by ensuring farmers' access to more secure arable land. In addition, improved marketing structures, favourable price policies and institutional change are important requisites. It is also argued that the FSP is not a deliberate strategy to perpetuate black farmers as the FSP contributed significantly to the economic well-being of the small farmers. However, certain policies will have to be reviewed to increase access to improve all other services. Finally it would appear that presently and even in the post-apartheid South Africa the sustainability of the FSPs will depend on land reform and institutional change, price policies and improved marketing systems.

description: Infrared observations of Sgr A* probe the region close to the event horizon of the black hole at the Galactic center. These observations can constrain the properties of low-luminosity accretion as well as that of the black hole itself. The GRAVITY instrument at the ESO VLTI has recently detected continuous circular relativistic motion during infrared flares which has been interpreted as orbital motion near the event horizon. Here we analyze the astrometric data from these flares, taking into account the effects of out-of-plane motion and orbital shear of material near the event horizon of the black hole. We have developed a new code to predict astrometric motion and flux variability from compact emission regions following particle orbits. Our code combines semi-analytic calculations of timelike geodesics that allow for out-of-plane or elliptical motions with ray tracing of photon trajectories to compute time-dependent images and light curves. We apply our code to the three flares observed with GRAVITY in 2018. We show that all flares are consistent with a hotspot orbiting at R$\sim$9 gravitational radii with an inclination of $i\sim140^\circ$. The emitting region must be compact and less than $\sim5$ gravitational radii in diameter. We place a further limit on the out-of-plane motion during the flare.

description: The purpose of this paper is to add new evidence to studies already done on factors associated with surplus producers and on the food price dilemma in traditional agriculture. Survey data of rural households in the FSP areas in KaNgwane was used to determine the factors which discriminate between surplus and deficit producers and to establish a market participation profile to illustrate the extent of the food price dilemma. In the second half of the paper these results are compared with the results from similar studies. Through comparing the results it was possible to obtain a better picture as to what factors determine surplus producers in traditional agriculture. By analysing the market participation profile in the various areas it is also possible to determine the extent of the food price dilemma in Southern Africa. The results obtained from the survey data in KaNgwane were in line with those from the other studies.

description: We investigate the Berezinskii-Kosterlitz-Thouless (BKT) scaling of the critical current of Josephson junction dynamics across a barrier potential in a two-dimensional (2D) Bose gas, motivated by recent experiments by Luick \textit{et al.} arXiv:1908.09776. Using classical-field dynamics, we determine the dynamical regimes of this system, as a function of temperature and barrier height. As a central observable we determine the current-phase relation, as a defining property of these regimes. In addition to the ideal junction regime, we find a multimode regime, a second-harmonic regime, and an overdamped regime. For the ideal junction regime, we derive an analytical estimate for the critical current, which predicts the BKT scaling. We demonstrate this scaling behavior numerically for varying system sizes. The estimates of the critical current show excellent agreement with the numerical simulations and the experiments. Furthermore, we show the damping of the supercurrent due to phonon excitations in the bulk, and the nucleation of vortex-antivortex pairs in the junction.

description: This paper examines food production and price policies in Zimbabwe from 1980 to 1989 with a particular reference to maize. The study evaluates the extent to which the current maize crisis in the country could be attributed to drought. The analysis shows that the price policy regimes in Zimbabwe during the 1980s distorted maize producer incentives and embedded subsidies that were questionable on an equitable ground. The policy myopia discouraged the large-scale commercial farmers from maize production and committed the task of supplying the country's staple food in the hands of drought-prone, limited-resource communal area farmers, thereby risking the country's potential for food security. Thus, the government prepared the stage for the current food crisis, so the drought merely aggravated the effect of short-sighted policies. Given a carefully drawn policy structure, Zimbabwe has the capacity to feed its people and minimise the effect of drought on the food distribution system.

description: Optimal control is highly desirable in many current quantum systems, especially to realize tasks in quantum information processing. We introduce a method based on differentiable programming to leverage explicit knowledge of the differential equations governing the dynamics of the system. In particular, a control agent is represented as a neural network that maps the state of the system at a given time to a control pulse. The parameters of this agent are optimized via gradient information obtained by direct differentiation through both the neural network \emph{and} the differential equation of the system. This fully differentiable reinforcement learning approach ultimately yields time-dependent control parameters optimizing a desired figure of merit. We demonstrate the method's viability and robustness to noise in eigenstate preparation tasks for three systems: a~single qubit, a~chain of qubits, and a quantum parametric oscillator.

description: An experimental evidence of subwavelength imaging with a "lens", which is a uniaxial negative permittivity wire medium slab, is reported. The slab is formed by gratings of long thin parallel conducting cylinders. Taking into account the anisotropy and spatial dispersion in the wire medium we theoretically show that there are no usual plasmons that could be exited on surfaces of such a slab, and there is no resonant enhancement of evanescent fields in the slab. The experimentally observed clear improvement of the resolution in the presence of the slab is explained as filtering out the harmonics with small wavenumbers. In other words, the wire gratings (the wire medium) suppress strong traveling-mode components increasing the role of evanescent waves in the image formation. This effect can be used in near-field imaging and detection applications.

description: We present deep optical long-slit spectra of 17 edge-on spiral galaxies of intermediate to late morphological type, mostly parallel to their major axes and in a few cases parallel to the minor axes.The line-of-sight stellar kinematics are obtained from the stellar absorption lines using the improvedc ross-correlation technique. In general, the stellar kinematics are regular and can be traced well into the disc-dominated region. The mean stellar velocity curves are far from solid-body, indicating that the effect of dust extinction is not large. The line-of-sight stellar disc velocity dispersion correlates with the galaxy maximum rotational velocity, but detailed modeling is necessary to establish whether this represents a physical relation. In four spirals with a boxy- or peanut-shaped bulge we are able to detect asymmetric velocity distributions, having a common signature with projected radius in the mean line-of-sight velocity and the $h_{3}$ and $h_{4}$ curves. In two cases this kinematic asymmetry probably represents the `figure-of-eight' pattern synonymous of a barred potential. We emphasize, however, that the signatures seen in the $h_{3}$ and $h_{4}$ curves may also be due to the disc seen in projection.

description: The two stage technology of porous carbonaceous material obtaining via pyrolysis in inert medium with subsequent activation by steam is well-known. While steam could be a suitable substance for pyrolysis as well, the single-staged technology for waste tires recycling is yet to be developed. A comparative analysis of the characteristics of the carbonaceous materials obtained by the single-staged steam pyrolysis of waste tires was carried out, which could provide theoretical background for development of such technology. The steam pyrolysis was performed in a tubular reactor in an overheated steam medium (500 °C with 5 kg/h mass flow rate). The technical characteristics of the obtained samples were evaluated in context of their potential for further application as absorbent and raw material for the rubber production according to Chemical Abstracts Service No. 1333-86-4. The composition and physical-chemical properties of the obtained samples were studied using BET and thermogravimetric analysis, atomic emission, transmission and scanning electron microscopies, Raman, X-ray diffraction and photoelectron spectroscopies. The results revealed that the structure and properties of all obtained carbonaceous material samples were similar. The samples consisted of amorphous carbon (with a disordered graphite lattice) and contained a significant amount of metal oxides. According to experimental data, zinc was present in the form of ZnO with a binding energy of 1022.4 eV, while sulfur was observed in the form of sulfide and oxysulfide with binding energies of 161.8 and 163.2 eV, respectively. According to electron microscopy, the morphology of samples was represented by a set of spherical agglomerates comprising nanosized particles. According to the BET analysis of the samples, the specific surface area was varieb in range between 52.0 and 66.0 m2/g, the pore volume values were within a range of 0.53–0.87 cm3/g while the average pore size was varied from 412 to 527 Å.

description: The study compares the socio-economic characteristics of the participants and non- participants in Village Alive Development Initiate (VADI); Identify the constraints faced by participants and non-participants in securing the credit and evaluate the impact of the scheme on their crop productivity in the study area. One hundred and eighty-eight farming households were selected in the participating villages in Kwara State, Nigeria. Data were collected by structured questionnaire and administered through personal interview. Analytical tools used were descriptive statistics and Propensity Score matching technique. The result showed that about 71% of the participants were females, 78% are between the ages 30-60, 64% married, 57% had at least primary school education and about 81% had access to market information. Although the participants of VADI programme had other source of credit but the largest part of the funds came from VADI (59.09%). The result of the Likert scale technique used to analyse the constraint faced in credit acquisition showed that possibility of loan default by members ranked 1st followed by lack of collateral and guarantor and then loan rational habit. It was also revealed that VADI programme increased the productivity of participating farming household by 315.55 Kg/ha, hence such initiative on credit acquisition should be encouraged and sustained among farming households in the study area.
The nature of slow dynamics in a minimal model of frustration-limited domains

description: We present simulation results for the dynamics of a schematic model based on the frustration-limited domain picture of glass-forming liquids. These results are compared with approximate theoretical predictions analogous to those commonly used for supercooled liquid dynamics. Although model relaxation times increase by several orders of magnitude in a non-Arrhenius manner as a microphase separation transition is approached, the slow relaxation is in many ways dissimilar to that of a liquid. In particular, structural relaxation is nearly exponential in time at each wave vector, indicating that the mode coupling effects dominating liquid relaxation are comparatively weak within this model. Relaxation properties of the model are instead well reproduced by the simplest dynamical extension of a static Hartree approximation. This approach is qualitatively accurate even for temperatures at which the mode coupling approximation predicts loss of ergodicity. These results suggest that the thermodynamically disordered phase of such a minimal model poorly caricatures the slow dynamics of a liquid near its glass transition.
