Astropy Proposal for Enhancement 6: Enhanced Character Separated Values table format (APE 6)
Creators: name: Aldcroft, Tom
name: Taylor, Mark
Publisher: name: Zenodo
Year: 2021

description: Data tables in astronomical analysis frequently contain additional metadata beyond just the column names and data values. Common attributes include the numerical data type, the physical unit, and a longer textual description of the column content. These attributes can be reprented in binary formats such as FITS, but the available options for a text-only format are inadequate. APE6 proposes to fill this void by specification of a standard for the interchange of tabular data in a text-only format. The format handles the key issue of serializing column specifications and table metadata by using a YAML-encoded data structure. The actual tabular data are stored in a standard character separated values (CSV) format, giving compatibility with a wide variety of non-specialized CSV table readers. Using YAML makes it extremely easy for applications *and humans* to read both the standardized data format elements (e.g. column name, type, description) as well as complex metadata structures. YAML also lends itself to simple table modifications by humans in a plain text editor. The reference Python implementation in ``astropy.io.ascii`` is relatively straightforward and will provide a significant benefit of allowing text serialization of most astropy Table objects, persistent storage, and subsequent interchange with other users. Although developed in the context of Astropy, there is nothing astronomy-specific in this format and it could be useful for other domains or languages. However, promoting that is beyond the scope of this APE.

description: The proton-rich isotope 68Br was discovered in secondary fragmentation reactions of fast radioactive beams. Proton-rich secondary beams of 70,71,72Kr and 70Br, produced at the RIKEN Nishina Center and identified by the BigRIPS fragment separator, impinged on a secondary 9Be target. Unambiguous particle identification behind the secondary target was achieved with the ZeroDegree spectrometer. Based on the expected direct production cross sections from neighboring isotopes, the lifetime of the ground or long-lived isomeric state of 68Br was estimated. The results suggest that secondary fragmentation reactions, where relatively few nucleons are removed from the projectile, offer an alternative way to search for new isotopes, as these reactions populate preferentially low-lying states.

description: 3D scan registration is a classical, yet a highly useful problem in the context of 3D sensors such as Kinect and Velodyne. While there are several existing methods, the techniques are usually incremental where adjacent scans are registered first to obtain the initial poses, followed by motion averaging and bundle-adjustment refinement. In this paper, we take a different approach and develop minimal solvers for jointly computing the initial poses of cameras in small loops such as 3-, 4-, and 5-cycles. Note that the classical registration of 2 scans can be done using a minimum of 3 point matches to compute 6 degrees of relative motion. On the other hand, to jointly compute the 3D registrations in n-cycles, we take 2 point matches between the first n-1 consecutive pairs (i.e., Scan 1 & Scan 2, ... , and Scan n-1 & Scan n) and 1 or 2 point matches between Scan 1 and Scan n. Overall, we use 5, 7, and 10 point matches for 3-, 4-, and 5-cycles, and recover 12, 18, and 24 degrees of transformation variables, respectively. Using simulations and real-data we show that the 3D registration using mini n-cycles are computationally efficient, and can provide alternate and better initial poses compared to standard pairwise methods.

description: Recent results concerning the topological properties of random geometrical sets have been successfully applied to the study of the morphology of clusters in percolation theory. This approach provides an alternative way of inspecting the critical behaviour of random systems in statistical mechanics. For the 2d q-states Potts model with q <= 6, intensive and accurate numerics indicates that the average of the Euler characteristic (taken with respect to the Fortuin-Kasteleyn random cluster measure) is an order parameter of the phase transition.

description: This paper employed the endogenous switching regression and propensity score matching methods to analyse the impact of row-planting technology on rice productivity using 470 rice farms in Northern Ghana. The empirical findings showed that the adoption of row-planting technology exerted greater positive impact on rice yields of smallholder farmers. In addition, rice yields of adopters and non-adopters are driven by farm inputs, socioeconomic, institutional and technological factors. We suggest that achieving self-sufficiency in rice and rural economic transformation in sub-Saharan Africa requires promotion of agricultural technologies including row-planting. Different specific policy interventions are also required to promote rice yields for adopters and non-adopters.

description: We test the recently proposed (Mediavilla et al. 2018) black hole mass scaling relationship based on the redshift {with respect to the quasar's rest frame} of the Fe III$λλ$2039-2113 line blend. To this end, we fit this feature in the spectra of a well suited sample of quasars, observed with X-shooter at the Very Large Telescope (VLT), whose masses have been independently estimated using the virial theorem. For the quasars of this sample we consistently confirm the redshift of the Fe III$λλ$2039-2113 blend and find that it correlates with the squared widths of H$β$, H$α$ and Mg II, which are commonly used as a measure of $M_{BH}/R$ to determine masses from the virial theorem. The average differences between virial and Fe III$λλ$2039-2113 redshift based masses are 0.18$\pm 0.21$ dex, 0.18$\pm 0.22$ dex and 0.14$\pm 0.21$ dex, when the full widths at half maximum (FWHM) of the H$β$, H$α$ and MgII lines are, respectively, used. The difference is reduced to 0.10$\pm 0.16$ dex when the standard deviation, $σ$, of {the} MgII line is used, instead. We also study the high S/N composite quasar spectra of the Baryon Oscillation Spectroscopic Survey (BOSS), finding that the Fe III$λλ$2039-2113 redshifts and Mg II squared widths, $FWHM_{MgII}^2$, match very well the correlation found for the individual quasar spectra observed with X-shooter. This correlation is expected if the redshift is gravitational.

description: This study determined the technical efficiency (TE) of production of Quality Protein Maize (QPM) and the effect on the adoption of QPM in Oyo State, Nigeria. QPM is an improved maize variety developed to reduce protein deficiency problems. A total of 100 maize farmers were sampled through a two-stage sampling procedure. Stochastic frontier approach using maximum likelihood estimation (MLE) was used to analyse the TE in the production of QPM, while probit regression was used to determine the effect of TE and other socioeconomic characteristics of the respondents on the adoption of QPM. The results revealed a mean TE of 0.89 and 0.78 for adopters and non-adopters of QPM respectively. This implied that adopters of QPM are more technically efficient than the non-adopters. Quantity of seed planted and fertilizer directly and significantly affected the TE of QPM while gross margin of maize farmers and income from other sources (at P<0.05), the level of education of farmers and QPM farm size (P<0.01) have significant and a negative effects on technical inefficiency from the results of the Tobit regression. The age (P<0.05) of the farmer has direct effect on technical inefficiency. In conclusion, TE, level of output, information availability on QPM and early maturity were significant determinants of QPM rather than the gross margin of production. Farmers decide to adopt QPM technology because of the high level of technical efficiency in the production of this variety. Their output from QPM can be increased by 11 percent, while the non-adopters can increase their maize output by 22 percent using the available technology.

description: We propose a spin field-effect transistor based on spin-orbit (s-o) coupling of both the Rashba and the Dresselhaus types. Differently from earlier proposals, spin transport through our device is tolerant against spin-independent scattering processes. Hence the requirement of strictly ballistic transport can be relaxed. This follows from a unique interplay between the Dresselhaus and the (gate-controlled) Rashba interactions; these can be tuned to have equal strengths thus yielding k-independent eigenspinors even in two dimensions. We discuss implementations with two-dimensional devices and quantum wires. In the latter, our setup presents strictly parabolic dispersions which avoids complications arising from anticrossings of different bands.

We study laser scattering of convection rolls to characterize the wavelengths and the trajectories of the stochastic amplitudes of the intermittent structures. The pattern wavelengths and the statistics of these trajectories are in quantitative agreement with simulations of the linearized electrohydrodynamic equations. The fundamental $τ^{-3/2}$ distribution law for the durations $τ$ of laminar phases as well as the power law of the amplitude distribution of intermittent bursts are confirmed in the experiments. Power spectral densities of the experimental and numerically simulated trajectories are discussed.

description: Using a farm household data from 3 agroecological zones of Ghana, this paper investigates the causal relationship between the adoption of improved maize variety and technical efficiency or productivity. The empirical results show a positive relationship between the adoption of improved maize variety and technical efficiency or productivity of farmers in the Semi-deciduous forest and Guinea Savannah zones. Generally, adopters of improved maize variety are about 6% to 8% more efficient than non-adopters. The estimated percentage increase in productivity due to the adoption of improved maize variety is about 53%. In the Semi-deciduous forest agroecological zone, adopters of improved maize variety are about 25% to 36% more efficient than non-adopters whilst in the Guinea Savannah agroecological zone, adopters of improved maize variety are about 15% to 26% more efficient than non-adopters. The estimated percentage increase in productivity due to adoption of the improved maize variety is about 8% in the Semi-deciduous forest zone and about 11% in the Guinea Savannah zone. The impact of adoption on technical efficiency in the Transitional zone is however negative. Adopters of improved maize variety are 7% to 8% less efficient than non-adopters and the estimated percentage decrease in productivity due to adoption of the improved maize variety is about 15%. Food safety net policies should pay attention to increased development and dissemination of improved crop varieties suitable to different agroecological zones.

description: This research analyses factors that influence the adoption of combination of improved groundnut seed, inorganic fertilizer, and organic fertilizer in eastern Ethiopia using a cross sectional data collected from 300 sample groundnut farming households. Multivariate probit and ordered probit models are used to identify factors affecting adoption of multiple technologies. Tobit model is used to spot the determinants of intensity of adoption of improved seed. The results show a strong correlation between improved seed and inorganic fertilizer adoption, indicating the simultaneous adoption decision of farmers. Age of the household head negatively affects the adoption decision of improved seed while education, groundnut farming experience, extension contact, training and plot size are positive contributors.

description: We present the first experimental realisation of Bose-Einstein condensation in a purely magnetic double-well potential. This has been realised by combining a static Ioffe-Pritchard trap with a time orbiting potential (TOP). The double trap can be rapidly switched to a single harmonic trap of identical oscillation frequencies thus accelerating the two condensates towards each other. Furthermore, we show that time averaged potentials can be used as a means to control the radial confinement of the atoms. Manipulation of the radial confinement allows vortices and radial quadrupole oscillations to be excited.

description: Potato production plays an important role in improving household income and nutrition and thereby contributes to food security. Despite of this, the current productivity of the crop is below the potential. Low level of use of improved potato technology package is among the causes for low productivity. In this context, this study analysed the factors influencing adoption of potato technology package by smallholder farmers in Gurawa, Haramaya, Kombolcha, Meta, and Habro districts of Eastern Ethiopia. The analysis was based on a household survey conducted on 214 randomly selected potato growing households. A two-limit Tobit model was used to analyse the factors affecting adoption which is measured in an index computed from five components of the technology package. Variation in districts, access to irrigation, farm size, membership to cooperatives, and annual income of the households were found to significantly affect the adoption of potato technology package. Policy makers, planners and development practitioners are required to give due attention to these determinants in order to support smallholder farmers in production and productivity improvements from potato production.

Dynamic principal component regression: Application to age-specific mortality forecasting

description: In areas of application, including actuarial science and demography, it is increasingly common to consider a time series of curves; an example of this is age-specific mortality rates observed over a period of years. Given that age can be treated as a discrete or continuous variable, a dimension reduction technique, such as principal component analysis, is often implemented. However, in the presence of moderate to strong temporal dependence, static principal component analysis commonly used for analyzing independent and identically distributed data may not be adequate. As an alternative, we consider a \textit{dynamic} principal component approach to model temporal dependence in a time series of curves. Inspired by Brillinger's (1974) theory of dynamic principal components, we introduce a dynamic principal component analysis, which is based on eigen-decomposition of estimated long-run covariance. Through a series of empirical applications, we demonstrate the potential improvement of one-year-ahead point and interval forecast accuracies that the dynamic principal component regression entails when compared with the static counterpart.

We also develop a variant of this method, aimed to reduce the degree of non-linearity of the lower-order equation. Some applications of these methods are carried out and, in particular, we show that second-order Emden-Fowler equations can be transformed into first-order Abel equations. The work presented here is a generalization of a method used by Majorana in order to solve the Thomas-Fermi equation.

description: We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of a Balmer filament in the northeast region of the Cygnus Loop supernova remnant. The data consist of one spectrum obtained through the 30"x30" (LWRS) aperture and three spectra at adjacent positions obtained through the 4"x20" (MDRS) aperture. The nonradiative shocks in the region giving rise to these faint optical filaments produce strong OVI 1032,1038 emission, which is detected in all the spectra. The OVI emission is resolved by FUSE into a strong component centered at 0 km/s, and weaker components centered at +/- 140 km/s. The MDRS spectra allow us to study the variation of OVI emission in the post-shock structure. We find that the zero velocity emission is associated directly with the Balmer filament shock, while the high velocity emission comes from a more uniformly distributed component elsewhere along the line of sight. We also find that the shocks producing the emission at +/- 140 km/s have velocities between 180 km/s and 220 km/s, if we assume that the ram pressure driving them is the same as for the zero velocity component shock. In the context of the cavity model for the Cygnus Loop, the interaction of the blast wave with the spherical shell that forms most of the cavity wall can naturally give rise to the similar red and blue-shifted components that are observed.

description: Dokument erstellt im Zusammenhang mit Projekt TrilaWatt /// Zusammenfassung: TrilaWatt Daten- und Analyseprodukte können genutzt werden, um Trassierung von Bauwerken, wie beispielsweise Stromkabeln, auf bzw. unter dem Meeresboden zu untersuchen. Die Durchführung einer Trassierung umfasst die Untersuchung der geologischen, ökologischen und hydrodynamischen Eigenschaften des Gebiets sowie die Bewertung potenzieller Risiken. Durch Dateninnovation und die Entwicklung von webbasierten Werkzeugen im TrilaWatt Projekt wird die Ermittlung von effizienten Trassen unterstützt. So können langfristig Auswirkungen auf die Umwelt und die Bau- und Wartungskosten minimiert werden. Im TrilaWatt Terria System wurde eine WPS-Funktionalität implementiert, die aus einer Anzahl an Topographie-Datensätzen die tiefste Gewässersohle finden kann, um so eine notwendige Verlegetiefe zu bestimmen. Weitere Datenprodukte geben Aufschluss über die Höhenlage des Meeresbodens bzw. über die morphologische Aktivität innerhalb eines Betrachtungszeitraums.

description: The scale of modern surveillance and the debate surrounding its nature have become expansively complex. Consequently, the field of communication and surveillance studies represent a critical area of scholarship with interwoven academic, policy and social implications. This thesis, a critical ideological study of modern surveillance founded upon an empirical study, draws on participant observation, militant ethnography and semistructured interviews as research methods. From a participant insider perspective, it explores and interprets the experiences, meanings and views of counter-surveillance actors targeted by surveillance based on participant observation and militant ethnography conducted during the 2017 Chaos Communication Congress in Leipzig and the 2019 Chaos Communication Camp in Mildenberg, Germany. Drawing on Jeffrey Juris’ militant ethnography and based on the participants’ own experiences in resisting modern surveillance, I focus on the lessons learned from those belonging to the third-wave of privacy activism. Through their personal experiences, this research reveals control strategies, lessons learned and views of privacy activists, hacktivists and civic-hackers on the state of modern surveillance. This thesis concludes that the current symbiotic nature of the state-corporate surveillance and disinformation nexus means any legislative solution to be unlikely.

description: Quantum corrals are two dimensional structures built atom by atom on an atomically clean metallic surface using a scanning tunneling microscope. These two dimensional structures ``corral'' electrons in the surface states of noble metals which lead to standing wave patterns in the electron density inside the quantum corral. We review the physics of quantum corrals and relate the signal of the scanning tunneling microscope to the scattering properties of substrate electrons from atomic impurities supported on the surface. The theory includes the effects of incoherent surface state electron scattering at the impurities and quantitively describes all of the current STM data on quantum corrals, including the recent quantum mirage experiments with Kondo effect. We discuss the physics underlying the recent mirage experiments and review some of the outstanding questions regarding Kondo effect from impurities in nanoscale structures on metallic surfaces. We also summarize recent work on variations of ``quantum'' corrals: optical corrals and acoustical corrals.

description: Peter Clarricoats made fundamental contributions as a microwave engineer in the fields of applied electromagnetics for microwave and optical waveguides, and microwave antenna feeds. Peter was also a pioneer of optical fibres, and established the theory of electromagnetic propagation on dielectric and ferrite structures. In the course of this, he discovered that such structures can, under some conditions, support ‘backward waves’ and that guides can propagate complex modes. Over 40 years of his academic career, Peter Clarricoats had numerous notable achievements, including pioneering designs for shaped reflectors, reconfigurable reflectors and especially corrugated horns for microwave antennas. The latter are now universally used in satellite ground stations and in spacecraft. He published what became standard reference texts on corrugated horns for microwave antennas, microwave horns and feeds.He served as vice-president of both the Institution of Engineering and Technology and the International Union of Radio Science, and from 1998 to 2000 was chairman of the Defence Scientific Advisory Council. He was appointed a CBE in 1996. He is the recipient of the 2001 Distinguished Achievement Award of the Institute of Electrical and Electronics Engineers Antennas and Propagation Society, and in 2015 he received the Sir Frank Whittle Gold Medal from the Royal Academy of Engineering.

description: We study maps preserving the Heisenberg commutation relation $ab - ba=1$. We find a one-parameter deformation of the standard realization of the above algebra in terms of a coordinate and its dual derivative. It involves a non-local ``coordinate'' operator while the dual ``derivative'' is just the Jackson finite-difference operator. Substitution of this realization into any differential operator involving $x$ and $\frac{d}{dx}$, results in an {\em isospectral} deformation of a continuous differential operator into a finite-difference one. We extend our results to the deformed Heisenberg algebra $ab-qba=1$. As an example of potential applications, various deformations of the Hahn polynomials are briefly discussed.

description: Metasurfaces with strongly anisotropic optical properties can support deep subwavelength-scale confined electromagnetic waves (polaritons) that promise opportunities for controlling light in photonic and optoelectronic applications. We develop a mid-infrared hyperbolic metasurface by nanostructuring a thin layer of hexagonal boron nitride supporting deep subwavelength-scale phonon polaritons that propagate with in-plane hyperbolic dispersion. By applying an infrared nanoimaging technique, we visualize the concave (anomalous) wavefronts of a diverging polariton beam, which represent a landmark feature of hyperbolic polaritons. The results illustrate how near-field microscopy can be applied to reveal the exotic wavefronts of polaritons in anisotropic materials, and demonstrate that nanostructured van der Waals materials can form a highly variable and compact platform for hyperbolic infrared metasurface devices and circuits.
