description: We report the discovery and panchromatic followup observations of the young Type Ic supernova, SN2020oi, in M100, a grand design spiral galaxy at a mere distance of $14$ Mpc. We followed up with observations at radio, X-ray and optical wavelengths from only a few days to several months after explosion. The optical behaviour of the supernova is similar to those of other normal Type Ic supernovae. The event was not detected in the X-ray band but our radio observation revealed a bright mJy source ($L_ν \approx 1.2 \times 10^{27} {\rm erg\,s}^{-1} {\rm Hz}^{-1}$). Given, the relatively small number of stripped envelope SNe for which radio emission is detectable, we used this opportunity to perform a detailed analysis of the comprehensive radio dataset we obtained. The radio emitting electrons initially experience a phase of inverse Compton cooling which leads to steepening of the spectral index of the radio emission. Our analysis of the cooling frequency points to a large deviation from equipartition at the level of $ε_e/ε_B \gtrsim 200$, similar to a few other cases of stripped envelope SNe. Our modeling of the radio data suggests that the shockwave driven by the SN ejecta into the circumstellar matter (CSM) is moving at $\sim 3\times 10^{4}\,{\rm km\,s}^{-1}$. Assuming a constant mass-loss from the stellar progenitor, we find that the mass-loss rate is $\dot{M} \approx 1.4\times 10^{-4}\,{M}_{\odot}\,{\rm yr}^{-1}$, for an assumed wind velocity of $1000\,{\rm km\,s}^{-1}$. The temporal evolution of the radio emission suggests a radial CSM density structure steeper than the standard $r^{-2}$.

description: Lagrangians for several new off-shell 4D, N = 1 supersymmetric descriptions of massive superspin-1 and superspin-3/2 multiplets are described. Taken together with the models previously constructed, there are now four off-shell formulations for the massive gravitino multiplet (superspin-1) and six off-shell formulations for the massive graviton multiplet (superspin-3/2). Duality transformations are derived which relate some of these dynamical systems.

Reading the earth : multivariate analysis of feature functions at Xá:ytem (the Hatzic Rock Site, DgRn 23), British Columbia
Creators: name: Ormerod, Patricia Laura
Publisher: name: University of British Columbia
Year: 2009

description: This paper summarizes the results of a multivariate analysis to determine the functions of features, dating between ca. 7000 BP and 4500 BP, at Xá:ytem (the Hatzic Rock site, DgRn 23) in the lower Fraser River valley, British Columbia. From postulated feature functions, site use and subsistence activities are compared with the culture history for the region. As at other Old Cordilleran sites, Xá:ytem ca. 7000 BP likely served as a field camp where foragers gathered and consumed local resources in late summer and autumn. Around 5000 years ago, Charles culture people visited the site to gather, process, and possibly store local resources during summer and autumn. There is limited data suggesting that around 4500 BP, use of the site changed from processing local resources only to processing resources gathered in other ecological niches as well. Structures, storage, and lithic evidence all suggest that Xá:ytem ca. 4500 BP is different from St. Mungo phase sites of the Fraser River delta and exhibits a river valley adaptation of Charles culture. However, as at other Charles culture sites, Xá:ytem was not occupied year round, but may have been visited in spring, summer and autumn.

description: The initial conditions for the density perturbations in the early Universe, which dictate the large scale structure and distribution of galaxies we see today, are set during inflation. Measurements of primordial non-Gaussianity are crucial for distinguishing between different inflationary models. Current measurements of the matter power spectrum from the CMB only constrain this on scales up to $k\sim 0.1$ Mpc$^{-1}$. Reaching smaller angular scales (higher values of $k$) can provide new constraints on non-Gaussianity. A powerful way to do this is by measuring the $\textrm{H}\textrm{I}$ matter power spectrum at $z\gtrsim30$. In this paper, we investigate what values of $k$ can be reached for the LOw Frequency ARray (LOFAR), which can achieve $\lesssim$1$''$ $\,$resolution at $\sim$50 MHz. Combining this with a technique to isolate the spectrally smooth foregrounds to a wedge in $k_{\parallel}$ - $k_{\perp}$ space, we demonstrate what values of $k$ we can feasibly reach within observational constraints. We find that LOFAR is $\sim$5 orders of magnitude away from the desired sensitivity, for 10 years of integration time.

description: Public and private sector institutions in KwaZulu-Natal (KZN), South Africa (SA) can identify policies and strategies to increase the survival and growth rates of small, medium and micro-enterprise (SMME) agribusinesses if they have more information about the factors that constrain business performance. The sustained growth of these SMMEs could, in turn, help to reduce poverty, income inequality and unemployment problems in the province. The owners of 44 agribusiness SMMEs in a stratified random sample of Ithala Development Finance Corporation clients in KZN were, therefore, surveyed during October 2003 and January 2004 to identify what factors they perceive constrain business survival and growth. The respondents identified eight dimensions of constraints, namely: a lack of access to services; funding constraints at start-up; lack of management capacity in the enterprise; access to tender contracts; compliance costs associated with VAT and labour legislation; liquidity stress; lack of collateral; and lack of institutional support. The provision of appropriate infrastructure and training, development of innovative loan products, and policies to reduce the cost of compliance with legislation affecting agribusiness SMMEs are some possible solutions to help deal with these constraints.
Integrated warm- and cool-season grass equine rotational grazing systems: pasture production, grazing behavior, metabolism, and the gut microbiome

description: Incorporating warm- and cool-season grasses (WSG, CSG) into an integrated rotational grazing system (IRS) may address challenges presented by the “summer slump” typical of traditional CSG horse pastures. This project evaluated production implications of IRS as well as effects on grazing behavior, glycemic and insulinemic responses, and the fecal microbiota of grazing horses. Crabgrass (CRB) integration resulted in greater summer yield. Monoculture establishment of CRB produced greater yield than interseeding. The EquiWatch System was validated for reporting grazing activity and was utilized for subsequent investigations of pasture forage preference. Results of preference trials and assessments of circulating glucose and insulin (CRB vs. CSG) were inconsistent between small-plot or restricted-area grazing experiments and responses in the full-pasture setting, with minimal differences found in full-pasture setting under normal grazing management conditions. Glycemic responses to oral sugar tests were greater for horses adapted to WSG vs. CSG, but insulinemic responses did not differ. All GLU and INS were within normal ranges for all experiments. Fecal microbial structure and composition were stable across transitions between WSG and CSG within IRS, but differed following adaptation to individual forages. Forage crude protein and non-structural carbohydrates influenced fecal microbial composition. Interrelationships were found between these nutrients, glycemic responses, and Akkermansia and Clostridium butyricum. These bacteria were also enriched in horses adapted to WSG. Overall, these findings support implementation of IRS for increasing summer pasture yield and indicate minimal impacts on metabolic status of healthy grazing horses. Horses may be transitioned between WSG and CSG in IRS without substantial impacts on the gut microbiota, but shifts in the microbiota are apparent after adaptation to differing forages within IRS.

description: We demonstrate a recognition and feature visualization method that uses a deep convolutional neural network for Raman spectrum analysis. The visualization is achieved by calculating important regions in the spectra from weights in pooling and fully-connected layers. The method is first examined for simple Lorentzian spectra, then applied to the spectra of pharmaceutical compounds and numerically mixed amino acids. We investigate the effects of the size and number of convolution filters on the extracted regions for Raman-peak signals using the Lorentzian spectra. It is confirmed that the Raman peak contributes to the recognition by visualizing the extracted features. A near-zero weight value is obtained at the background level region, which appears to be used for baseline correction. Common component extraction is confirmed by an evaluation of numerically mixed amino acid spectra. High weight values at the common peaks and negative values at the distinctive peaks appear, even though the model is given one-hot vectors as the training labels (without a mix ratio). This proposed method is potentially suitable for applications such as the validation of trained models, ensuring the reliability of common component extraction from compound samples for spectral analysis.

description: Economists and statisticians constructing the national income accounts usually overlook the many benefits derived by communities from natural forests and woodlands. This study attempted to impute a value for the ecosystem services of these resources in Swaziland employing an environmental accounting framework. The current measure of national income was found to underestimate GDP by 2% and under value national savings by 10% by not accounting for the flow and asset values of natural forests and woodlands. The study also revealed a very high dependence of the rural communities in Swaziland on natural forests and woodlands for their livelihoods as they derive more than 50% of the value of total household consumption expenditure from these resources. These results clearly indicate the significant contribution to and crucial role these resources play in the lives and wellbeing of the Swazi people and hence the importance of prudent management and utilisation of this resource sector.

description: In the framework of the see-saw mechanism the normal hierarchy is favorable for the neutrino mass spectrum. For this spectrum we present a detailed calculation of the half-lives of neutrinoless double beta decay for several nuclei of experimental interest. The half-lives are evaluated by considering the most comprehensive nuclear matrix elements, which were obtained within the renormalized QRPA by the Bratislava-Caltech-Tuebingen group. The dependence of the half-lives on sin^2 theta_{13}$ and the lightest neutrino mass is studied. We present also the results of the calculations of the half-lives of neutrinoless double beta decay in the case of the inverted hierarchy of neutrino masses.

description: It is now well established that the majority of massive stars reside in multiple systems. However, the effect of multiplicity is not sufficiently understood, resulting in a plethora of uncertainties about the end stages of massive-star evolution. In order to investigate these uncertainties, it is useful to study massive stars just before their demise. Classical Wolf-Rayet stars represent the final end stages of stars at the upper-mass end. The multiplicity fraction of these stars was reported to be ${\sim}0.4$ in the Galaxy but no correction for observational biases has been attempted. The aim of this study is to conduct a homogeneous radial-velocity survey of a magnitude-limited ($V$ $\leq 12$) sample of Galactic Wolf-Rayet stars to derive their bias-corrected multiplicity properties. The present paper focuses on 12 northern Galactic carbon-rich (WC) Wolf-Rayet stars observable with the 1.2m Mercator telescope on the island of La Palma. We homogeneously measured relative radial velocities (RVs) for carbon-rich Wolf-Rayet stars using cross-correlation. Variations in the derived RVs were used to flag binary candidates. We investigated probable orbital configurations and provide a first correction of observational biases through Monte-Carlo simulations. Of the 12 northern Galactic WC stars in our sample, seven show peak-to-peak RV variations larger than 10 km s$^{-1}$, which we adopt as our detection threshold. This results in an observed spectroscopic multiplicity fraction of 0.58 with a binomial error of 0.14. In our campaign, we find a clear lack of short-period (P~$

description: Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or charge density waves (CDWs). Single-layer (SL) VSe$_2$ stands out in this regard because it exhibits a strongly enhanced CDW transition with a higher transition temperature compared to the bulk in addition to an insulating phase with an anisotropic gap at the Fermi level, causing a suppression of anticipated 2D ferromagnetism in the material. Here, we investigate the interplay of electronic and lattice degrees of freedom that underpin these electronic phases in SL VSe$_2$ using ultrafast pump-probe photoemission spectroscopy. In the insulating state, we observe a light-induced closure of the energy gap on a timescale of 480 fs, which we disentangle from the ensuing hot carrier dynamics. Our work thereby reveals that the phase transition in SL VSe$_2$ is driven by electron-lattice coupling and demonstrates the potential for controlling electronic phases in 2D materials with light.

description: Vegetable production constitutes an important sub-sector of the agricultural economy of KwaZulu-Natal. Most vegetables are cultivated in mixed-cropping types of farming systems. The technical efficiency of vegetable based cropping systems was estimated in order to identify the potential increase in production without incurring additional costs. The factors affecting technical efficiency and constraints and potential of the cropping system were also investigated. A field survey was conducted covering 120 vegetable farmers in the irrigated Tugela Ferry scheme and dryland farming sector in Msinga district during October to December 2003. According to a stochastic frontier production function using a Cobb-Douglas model, hired labour, organic fertilizer, inorganic fertilizer, area harvested and soil fertility maintenance cost showed significant positive effects on vegetable production. The mean technical efficiency of the vegetable based cropping systems was 84.32%. According to the inefficiency model the efficiency increased significantly as a result of farm visits by extension officers, participation in farmer training, less sloping lands, more experience, and higher diversity of the vegetable system. Technical efficiency decreased, however, with higher education level of the farmer and with higher off-farm income. Farm income is low due to low productivity, market constraints, lack of technology, and institutionally related constraints. Environmental conditions in the Msinga district are such that a high value crops can be grown with an adequate supply of irrigation water. There is a good possibility for stepping up production of these crops in marginal lands through appropriate crop diversification.

description: Precision astrometry from the second Gaia data release has allowed astronomers to predict 5,787 microlensing events, with 528 of these having maximums within the extended Gaia mission (J2014.5 - J2026.5). Future analysis of the Gaia time-series astrometry of these events will, in some cases, lead to precise gravitational mass measurements of the lens. We find that 61% of events predicted during the extended Gaia mission with sources brighter than G = 18 are likely to be spurious, with the background source in these cases commonly being either a duplicate detection or a binary companion of the lens. We present quality cuts to identify these spurious events and a revised list of microlensing event candidates. Our findings imply that half of the predictable astrometric microlensing events during the Gaia mission have yet to be identified.

description: After almost two decades of implementing structural and macroeconomic adjustment programmes, some West African countries continue to experience declining trends in per capita domestic food production, rising food imports and volatile food prices. Real food prices increased up to 7 percent per year during the 1980-1998 period. A vector error correction model was used in investigating the impacts of monetary and macroeconomic factors on food prices during the 1960-1998 period. Food price shocks have significant impacts on domestic food production, and are a major source of macroeconomic instability in West Africa. Trade, exchange rate and monetary policy reforms have significant impacts on food prices and domestic agricultural production. These policies influence consumption patterns, and have serious implications for poverty reduction, food security issues and agricultural growth in Africa.

description: Motivated by recent experiments we have studied the optical conductivity of DNA in its natural environment containing water molecules and counter ions. Our density functional theory calculations (using SIESTA) for four base pair B-DNA with order 250 surrounding water molecules suggest a thermally activated doping of the DNA by water states which generically leads to an electronic contribution to low-frequency absorption. The main contributions to the doping result from water near DNA ends, breaks, or nicks and are thus potentially associated with temporal or structural defects in the DNA.

Year: 2020

We investigated the uniaxial compressive behavior of damaged and intact alumina using quantitative X-ray computed tomography (XCT) analysis coupled with digital image correlation (DIC) for mechanical characterization. Internal three-dimensional crack characteristics such as crack surface area and orientation were quantified using XCT to assess the level of damage. From the quasi-static and dynamic stress–strain results, the primary effects of crack damage are to reduce the initial stiffness and rate of lateral expansion in damaged alumina. With increasing axial strain, crack closure was found to lead to a recovery of elastic properties, in some cases to intact levels, in the damaged specimens. Localized deformation mechanisms related to the crack structure, including lateral crack closure, axial crack opening and closing, and inclined crack sliding, were visualized in-situ and connected to XCT reconstructions. High-speed imaging also revealed a mixed fracture mode for damaged alumina that included axial splitting and failure along pre-existing cracks.

description: This study employed a Ricardian model that captures farmers' adaptation to analyze the impact of climate change on South African Sugarcane production under irrigation and dryland conditions. The study utilized time series data for the period 1977 to 1998 pooled over 11 districts. Results showed that climate change has significant nonlinear impacts on net revenue per hectare of sugarcane in South Africa with higher sensitivity to future increases in temperature than precipitation. Irrigation did not prove to provide an effective option for mitigating climate change damages on sugarcane production in South Africa. The study suggests that adaptation strategies should focus special attention on technologies and management regimes that will enhance sugarcane tolerance to warmer temperatures during winter and especially the harvesting phases.

We perform, in the chiral limit, computations of the relevant four-point current-current correlators, which depend upon self-interactions among the 5D bulk fields. Spontaneous chiral symmetry breaking ($χ$SB) is realized through boundary conditions on the bulk fields. Numerical results are analyzed in comparison with QCD, chiral perturbation theory ($χ$PT) and data, finding reasonable agreement with the experimental values of the $g_8$ and $g_{27}$ parameters describing the $ΔI =1/2,3/2$ decay channels.

description: 昨今, 様々な楽器を使ったバンド演奏が広く親しまれている. しかし, ドラムは ギターやキーボードといった楽器より 1 年あたりの販売個数が少なく, このことか らドラマー人口の少なさ, ドラマーを求めるミュージシャンが多いといった現状が 推測される. そのため, ドラムパートを自動演奏することでドラマーがいなくてもバンド演奏 が可能となる機器やシステムが多数開発・研究されている. しかし, これらのシス テムのほとんどは, あらかじめ決められたリズムパターンのデータを再生するだけ であり, ベロシティ(音の強弱) も一定か, あるいは事前に決められている. そのため, ジャズのように人がドラムを演奏することを前提としたジャンルでは, 演奏の 違和感につながる可能性がある. 本研究では, 出力のドラム演奏をより表現力豊かな演奏にするために, 他の演奏 パートを考慮してドラムパートのベロシティを自動で決定するドラム演奏システ ムを提案する. このシステムを構築する上で課題となるのが, ドラムパートのベロ シティをどのように決定するかである. 本システムではドラムパートの演奏を人間 による演奏に近づけるべきと考えるため, はじめに人間同士でのセッション演奏の 記録を行った. 演奏記録のデータからドラム演奏のベロシティ変化が曲全体の大 きなスケールでの変化と小節内の小さなスケールでの変化に二分できることがわ かったため, 本研究では大局的なベロシティ変化と局所的なベロシティ変化の 2 つ に分けたベロシティ表情付け手法を提案する. 大局的なベロシティ変化では記録し た演奏データをもとに重回帰分析を用いてドラムパートの次小節のベロシティ平均を予測し, 局所的なベロシティ変化ではドラムセット内の各楽器に応じてドラム パートの次小節のベロシティ平均からの偏差を算出する. ドラムパートの次小節の ベロシティ平均とその偏差を足し合わせたものが最終的に決定するベロシティと なる. 評価実験では, 大学のモダンジャズ研究会に所属するピアノ奏者が本システムを 用いてジャズのスタンダードナンバー 3 種類をドラムの大局的なベロシティを求 める式で使われる α の値を変えながら演奏し, ピアノ奏者へのアンケートと演奏 分析で評価を行った. 結果は, Bags Groove の曲を演奏した場合は α=0.5 の条件で キーボードパートとドラムパートの大局的なベロシティ間の相関に関しては人間 同士の演奏に近くなり, 提案手法が有効であることがわかったが, 他の曲を演奏し た場合では提案手法が有効でないことが考えられた

description: The main objective of the study was to examine the determinants of households' food security using a logistic regression procedure. The model was initially fitted with eleven factors, of which six were found to be significant, and all exhibited the expected signs. These include farmland size, ox ownership, fertilizer application, education level of household heads, household size, and per capita production. The result was analyzed further to compute partial effects and to conduct simulation studies on significant determinant factors. Analysis of partial effects revealed that an introduction to fertilizer use and an improvement in the educational levels of household heads lead to relatively greater probability of food security. On the other hand, simulations were conducted on the basis of the base category of farmers, representing food secure households, revealed that both educational levels of household heads and fertilizer application by farmers have relatively high potential to more than double the number of food secure households in the study area following improvements in these factors.

description: The use of the comparable sales method to value farm properties requires that professional valuers must think like a typical buyer of farm properties in a particular area. The Stellenbosch district, located on the periphery of the Cape Metropole, is a famous wine-producing area. The typical buyer is sophisticated and wealthy: someone for whom lifestyle could probably be just as important as the income generating capacity of the wine estate. A variety of site and situational factors have to be considered by the valuer: some of which are easily identifiable and quantifiable, where others are more elusive. This study aimed to identify and order the more important motivations as perceived by typical buyers in order to provide guidelines to valuers. An empirical study was done to determine buyers' and property characteristics, and buyers' ratings of possible motivations for buying land in Stellenbosch. Factor analysis provided a hierarchy of motivations. Terroir is the dominant site factor and the most important motivation, followed by location relative to Cape Town, the aesthetic beauty of the property, accessibility of the property, potential for new/more vineyards, meso-climate and the status of the address.

description: This paper extends a previous study in South Africa aimed at developing methodology for assessing the performance of equity-share schemes. The previous study proposed four broad criteria to measure performance: poverty alleviation; empowerment and participation; institutional arrangements and governance; and financial performance. This paper does not aim to assess the performance of existing equity-share schemes but to develop a methodology for the first three criteria based on empirical analysis of data gathered in 2004 from a land reform project in the Midlands of KwaZulu-Natal and seven established equity-share schemes in the Western Cape. Poverty alleviation is measured using a transition matrix of households grouped by four different symptoms of poverty: current income, wealth, health and a principal component index of housing quality. Eight categories of indicators are recommended for empowerment and participation: control and ownership; skills transfer; understanding; information; outcomes; trust; outreach; and participation. A scorecard applying norms based on empirical evidence gathered at the equity-share schemes in the Western Cape is used to test the indicators. A scorecard approach is also applied to institutional arrangements and governance, which are measured using three categories of indicators: accountability, transparency and property rights. The proposed performance measures are relevant, manageable in number and have feasible norms based on empirical evidence. These indicators and their norms need to be tested on a wider scale and monitored over time. Future research should be undertaken to determine weights for the empowerment and institutional indicators.

Risk and Uncertainty

description: In this article a mathematical model is presented to assist management decisions on an integrated crop and livestock farm. Risk is incorporated into the model as the negative deviation of the actual gross income from the expected value of an activity's gross income. The model includes crop production (permitting and optimising a crop rotation system), dairy production and wool sheep production. Relevant data from a farm in the Swartland region of the Western Cape were used to test and validate the model. The results show that the adoption of crop rotation is superior in terms of gross margin to that generated from a mono-crop strategy. Empirical results also indicate that the complex interrelationships involved in a mixed crop-livestock farm operation play a major role in determining optimal farm plans. These complex interrelationships favour the introduction of crop rotation in the crop production activities of the farm under investigation. Solutions of the model with risk indicate that the crop rotation strategy and animal production levels are sensitive to different risk levels, and that the incorporation of risk greatly affects the level of land allocation to crop rotation and animal production level of the farm. Finally, the results suggest that the introduction of crop rotation is of paramount importance in improving the profitability and sustainability of the farm, thus the inclusion of forage crops such as medics into the integrated crop-livestock production is beneficial for sustained profitability.

description: Significant transition strength in light $α$-conjugate nuclei at low energy, typically below 10 MeV, has been observed in many experiments. In this work the isoscalar low-energy response of N=Z nuclei is explored using the Finite Amplitude Method (FAM) based on the microscopic framework of nuclear energy density functionals. Depending on the multipolarity of the excitation and the equilibrium deformation of a particular isotope, the low-energy strength functions display prominent peaks that can be attributed to vibration of cluster structures: $α$+$^{12}$C+$α$ and $α$+$^{16}$O in $^{20}$Ne, $^{12}$C+$^{12}$C in $^{24}$Mg, 4$α$+$^{12}$C in $^{28}$Si, etc. Such cluster excitations are favored in light nuclei with large deformation.

description: We present X-ray light curves for the cataclysmic variable EX Hydrae obtained with the Chandra High Energy Transmission Grating Spectrometer and the Extreme Ultraviolet Explorer Deep Survey photometer. We confirm earlier results on the shape and amplitude of the binary light curve and discuss a new feature: the phase of the minimum in the binary light curve, associated with absorption by the bulge on the accretion disk, increases with wavelength. We discuss several scenarios that could account for this trend and conclude that, most likely, the ionization state of the bulge gas is not constant, but rather decreases with binary phase. We also conclude that photoionization of the bulge by radiation originating from the white dwarf is not the main source of ionization, but that it is heated by shocks originating from the interaction between the inflowing material from the companion and the accretion disk. The findings in this paper provide a strong test for accretion disk models in close binary systems.
