description: marginella (Canthecona) Dallas 1851: 89. [Fig. 104]
 Original data: “ ♁”; “a. Sierra Leone. Presented by the Rev. D.F. Morgan. ” [syntype (s)]
SYNTYPE ♁: blue-margined syntype disc; red-margined type disc; “87 a”; “ Canthecona marginella identified by Dallas.”; “a”; “NHMUK 010592170”. Fourth and fifth right antennomeres, second to fifth left antennomeres, and left posterior leg missing (Fig. 104).
 Current status: Afrius purpureus (Westwood, 1837) (first synonymised to Canthecona Yolofa (Guérin-Méneville, 1831), as a var. by Stål 1862a: 496; synonymised by Stål 1870: 44; see Roell et al. 2019: 25).
 Notes: Walker (1867a: 130) listed one specimen from Sierra Leone under the name Canthecona yolofa. It is likely that Dallas only described the species from this unique specimen (especially as he stated only one measurement and noted: “Antennae black (two apical joints wanting).” [emphasis ours]), but we cannot be sure, we therefore consider it a syntype. The label “87a” refers to the first specimen on page 87 in the first volume of Adam White’s unpublished “Catalogue of Hemiptera ” (White, A., no date) There, reference is made to a record in Samouelle’s Register: “Reg. 1224”. On page 182 of Samouelle’s Register (Entomological Memorandums, 1838 –1840), we can find information on the determination of the specimen: “ Pentatoma ” and on its provenance: “ Sierra Leone Rvd Morgan”. A cross-reference to White’s Catalogue of Hemiptera is as well noted: “Cat. Hem. II 87a”. For further informations on White’s Catalogue of Hemiptera and other early catalogues at the Museum, see Wheeler (1996).

description: marmorata (Canthecona) Dallas 1851: 90. [Fig. 108]
 Original data: “ ♁”; “a. S. Africa. Presented by the Earl of Derby.” [syntype (s)]
SYNTYPE ♁: blue-margined syntype disc; red-margined type disc; “Int. S. Africa / 43 19”; “3. CANTHECONA MARMORATA,”; “a”; “NHMUK 010592164”. Right middle and posterior legs missing (Fig. 108).
 Current status: Afrius purpureus (Westwood, 1837) (synonymised by Roell et al. 2019: 25).
 Notes: Walker (1867a: 130) listed only one specimen from the same provenance (South Africa, Earl of Derby); it is likely that Dallas described the species from this unique specimen but we cannot be totally sure, we therefore consider the specimen a syntype. Strangely, Thomas (1994: 151) wrote “the Holotype female of Canthecona marmorata Dallas was located in the BM(NH)”. Dallas described the species from one (or more) male, and we have also found a male in the collection; Thomas may have misread his notes. Because of the doubt he introduced as to the sex of the specimen, we cannot consider this as a valid lectotype designation by inference of the holotype.

Myths about new ultrahard phases: Why materials that are significantly superior to diamond in elastic moduli and hardness are impossible?

description: Reports published in the last 25 years on the synthesis of carbon-based materials significantly superior to diamond in hardness and elastic properties have been critically examined, and three groups of recently appearing myths have been analyzed. The first group concerns the possibility of producing materials with bulk moduli much higher than that of diamond. The second group regards to "experimentally measured" hardness significantly higher than that of diamond. Myths of the third group state that quantum confinement effects supposedly provide "theoretical" foundations for a several-fold (!) increase in the hardness of covalent materials. The fundamental impossibility of synthesizing materials with elastic moduli noticeably exceeding the diamond value under normal conditions has been demonstrated. The problems of hardness measuring have been discussed; it was shown that the formation of obstacles for motion of dislocations can allow increasing the measured hardness of superhard materials by 20-40%. It was demonstrated that other hypothetical ways for hardness increase, e.g. owing to quantum confinement have no any real physical grounds. The superior mechanical properties of diamond are due to reliably established physical laws. Accordingly, any statements on the possibility of obtaining materials with elastic characteristics and/or hardness several times higher than the corresponding values for diamond cannot be considered as scientifically reliable.

description: The objective of this research was to compute reference limits using reference values from patients entering pharmaceutical development clinical trials by the nonparametric method and the robust method of Horn and Pesce, with and without outlier exclusion, and compare the methods with respect to influence on the limits. Reference limits were computed for 38 analytes with over 130,000 subjects contributing reference values. Subjects were partitioned into 10 demographic strata for limit computation. Limits were computed for both 95- and 98-percentile reference intervals by both methods. For each reference interval and method, the limits were calculated with and without outliers. Outliers were excluded by the Horn algorithm. Irrespective of method, reference limits were expanded with the 98-percentile interval, but some expansions were small. Outlier exclusion contracted limits with more influence on the upper limit. The robust method contracted the upper limit to a meaningful degree and slightly expanded the lower limit for many analytes. Outlier exclusion and computation by the robust method have an increasing influence on analytes with right-skewed distributions of reference values from large populations not screened to exclude common, stable diseases and environmental factors that might affect analyte variability. The method has advantages for computation of reference limits used in clinical trial analyses.

description: Development of quantum engineering put forward new theoretical problems. Behavior of a single mesoscopic cell (device) we may usually describe by equations of quantum mechanics. However if experimentators gather hundreds of thousands of similar cells there arises some artificial medium that one already needs to describe by means of new electromagnetic equations. The same problem arises when we try to describe e.g. a sublattice structure of such complex substances like perovskites. It is demonstrated that the inherent primacy of vector potential in quantum systems leads to a generalization of the equations of electromagnetism by introducing in them toroid polarizations. To derive the equations of motion the Lagrangian and the Hamiltonian formalisms are used. Some examples where electromagnetic properties of molecules are described by the toroid moment are pointed out.

description: High frequency High Order Modes can significantly affect the coupled-bunch stability in a circular accelerator. With a large enough shunt impedance they may drive a coupled-bunch transverse instability. We have developed an analytical model and implemented it in the NHT Vlasov solver. The results show that the instability is characterized by the excitation of many azimuthal intra-bunch modes, which have similar growth rates, that make the traditional remedies such as a flat resistive feedback and chromaticity inefficient in suppressing it. For the High Luminosity Large Hadron Collider this could result in a significant increase of the stabilizing Landau octupole current, up to $\sim 100$ A ($\sim 20\%$ of the maximum available current). In order to limit the increase below 10 A ($\sim 2\%$), the transverse shunt impedance has to be kept below 1 M$Ω$/m.

Even simpler modeling of quadruply lensed quasars (and random quartets) using Witt's hyperbola

description: Witt (1996) has shown that for an elliptical potential, the four images of a quadruply lensed quasar lie on a rectangular hyperbola that passes through the unlensed quasar position and the center of the potential as well. Wynne and Schechter (2018) have shown that, for the singular isothermal elliptical potential (SIEP), the four images also lie on an `amplitude' ellipse centered on the quasar position with axes parallel to the hyperbola's asymptotes. Witt's hyperbola arises from equating the directions of both sides of the lens equation. The amplitude ellipse derives from equating the magnitudes. One can model any four points as an SIEP in three steps. 1. Find the rectangular hyperbola that passes through the points. 2. Find the aligned ellipse that also passes through them. 3. Find the hyperbola with asymptotes parallel to those of the first that passes through the center of the ellipse and the pair of images closest to each other. The second hyperbola and the ellipse give an SIEP that predicts the positions of the two remaining images where the curves intersect. Pinning the model to the closest pair guarantees a four image model. Such models permit rapid discrimination between gravitationally lensed quasars and random quartets of stars.

description: We construct a two component Ginzburg-Landau theory with coherent pair motion and incoherent quasiparticles for the phase diagram of $U_{1-x}Th_xBe_{13}$. The two staggered superconducting states live at the Brillouin zone center and the zone boundary, and coexist for temperatures $T\le T_{c2}$ at concentrations $x_{c1}\approx 0.02\le x \le x_{c2}\approx 0.04$. We predict below $T_{c2}$ appearance of a charge density wave (CDW) and Be-sublattice distortion. The distortion explains the $μ$SR relaxation anomaly, and Th-impurity mediated scattering of ultrasound to CDW fluctuations explains the attenuation peak.

 Notes: Walker (1867b: 341) had noted: “This may be a mere variety of S. reciproca.”, and indeed, the species was later synonymised to reciproca. The handwritten “M” on the disc label was the way Charles M. Allen, Alfred R. Wallace’s assistant recorded “Mysol” (Baker 1996: 173). The long label from Walker’s catalogue reads: “ ASOPUS MEGASPILUS.” While this is not the original combination, this is the one used by Walker (1868: 534).

description: Line segment detection is an important preprocessing step in Computer Vision applications. However, most of the existing algorithms are designed to be run on general purpose processors with high power consumption and will not achieve high framerates on low-cost embedded hardware. Furthermore, these algorithms are usually not suited for hard real-time applications. In this thesis, two novel methods are proposed: The first is an optimization for the Line Segment Detector (LSD), a widely used line segment detection algorithm, using a lookup table (LUT). We show that this optimization decreases the processing time by 13:08% on average, up to a maximum of 28:8%, while keeping 99:84% of the output identical. Secondly, a novel line segment detection algorithm is proposed, designed for implementation on field-programmable gate arrays (FPGAs). An implementation of this algorithm on a Xilinx XC7Z015 FPGA runs at 100 MHz while using less than 10% of the available on-chip resources. Images in 640x480 resolution can be processed at 325.5 frames per second and a latency of 32.27 us, while for the maximum resolution of 1080p (1920x1080) 48.23 frames per second can be achieved with an latency of 96.27 us. Additionally, the latency and throughput of the algorithm are only depending on the image resolution, but not on the image contents, making it compatible with hard real-time environments. The algorithm beats existing FPGA-based line segment detectors in terms of latency, while using less on-chip resources and achieving a comparable detection quality.

description: There is a consensus that entrepreneurs need to come up with new ideas, new products and services and organizing methods to be successful in their new ventures. However, entrepreneurship doesn’t necessarily need to invent, but take an existing idea and make it better. The advent of digital technolo-gies has provided entrepreneurs with myriad opportunities to be creative and create new ventures. The rise and growth of born digital organizations such as Uber, Airbnb and Alibaba.com are strongly attributed to the advancements in technologies. In this research, by conducting a qualitative document analysis for twenty-five South Asian start-ups, we explore how idea generation occurs in entrepre-neurs in developing countries. The study contributes to the academia and practice by introducing four idea generation strategies executed by entrepreneurs in developing countries.
qq' -> qq': a second look at the IR divergences

description: The transport properties of the quark-gluon plasma is important both from the point of view of the astrophysical systems and the heavy ion collisions. Therefore, accurate calculations of the elastic scattering cross-sections of $qq' \to qq'$ and $ q\qbar' \to q\qbar'$ processes are required. At the tree-diagram level exchange of massless gluons leads to divergent cross sections for such processes. An effective way to remove the infrared divergence is to introduce a Debye mass as an infrared regulator into the gluon propagator for the thermal gluons. In this work we find that at the two-gluon exchange level such a technique fails to remove the divergences. In a chiral symmetry broken phase the mass could be introduced following the standard procedure which cures the divergence. But in a chirally symmetric phase chiral invariant mass of the fermions needs to be considered.

description: Planck data robustly exclude the simple $λϕ^4$ scenario for inflation. This is also the case for models of Axion Inflation in which the inflaton field is the radial part of the Peccei-Quinn complex scalar field. In this letter we show that for the KSVZ model it is possible to match the data taking into account radiative corrections to the tree level potential. After writing down the 1-loop Coleman-Weinberg potential, we show that a radiative plateau is easily generated thanks to the fact that the heavy quarks are charged under $SU(3)_c$ in order to solve the strong CP problem. We also give a numerical example for which the inflationary observables are computed and the heavy quarks are predicted to have a mass $m_Q \gtrsim 10^3TeV$.

description: An implication of the spontaneous chiral symmetry breaking in QCD is that at low energy and resolution there appear quasiparticles - constituent quarks and Goldstone bosons. Thus, light and strange baryons should be considered as systems of three constituent quarks with confining interaction and a chiral interaction that is mediated by Goldstone bosons between the constituent quarks. We show how the flavor-spin structure and sign of the short-range part of the Goldstone boson exchange interaction reduces the $SU(6)_{FS}$ symmetry down to $SU(3)_F \times SU(2)_S$, induces hyperfine splittings and provides correct ordering of the lowest states with positive and negative parity. We present a unified description of light and strange baryon spectra calculated in a semirelativistic framework. It is demonstrated that the same short-range part of Goldstone boson exchange also induces strong short-range repulsion in $NN$ system when the latter is treated as $6Q$ system. Thus, all main ingredients of $NN$ interaction are implied by the chiral constituent quark model since the long- and intermediate-range attraction appears in the present framework due to pion and correlated two-pion exchanges between quarks belonging to different nucleons. We also find a very strong short-range repulsion in $ΛΛ$ system with $J^P=0^+$. It then suggests that the compact H-particle should not exist.

description: Sustainability means achieving people’s needs without compromising the ability of future generations to meet their needs, considering three domains including economic, social and environmental sustainability. Pulp and paper industry makes an enormous negative impact on environmental sustainability, and software development and usage also significantly effect on environmental sustainability. This research was carried out to determine environmental sustainability impact of open-source software reuse in development of Educational Management Information System and usage of open-source e-learning platform called Moodle during a year of time in the University of Moratuwa, Sri Lanka. Case study research methodology was used to analyse the data quantitatively and qualitatively. Research outcomes show that some components of environmental stainability concepts called three R's - Reduce, Reuse and Recycle can be achieved by using free and open-source software solutions. The case study showed that available open-source solution could reduce millions of papers used per year in a higher education institute. Medium-scale Management Information System development can reuse free and open-source software components and save hundreds of Gigawatt Hours of energy and dozens of e-waste computers produced by software development. Accordingly, this research concludes that there is a significant impact of free and open-source software paradigm for environmental sustainability in the higher education sector by reducing and reusing resources, especially in limited financial allocations in Information and Communications Technology development.

description: We present a theoretical study that investigates the applicability of a graph theoretical approach to realize various quantum experiments. Crucially, we may represent quantum optical experiments involving tabletop optical elements in terms of highly interpretable, coloured, weighted multi-graphs. We introduce the formalism behind this approach; then through the digital discovery framework PyTheus, we uncover over 100 different quantum experiments which realizes complex, novel quantum states. Towards enhancing our interpretation of the AI-based framework's solutions, we also leverage eXplainable-AI (XAI) techniques from computer vision to investigate what a trained neural network learns about quantum experiments. Crucially, we find that we are able to conceptualize the learned strategies which the neural network applies to optimize for a target quantum property, and discover how the network conceives of its solution. We conclude by presenting an experimental proposal which yields realizable solutions that, for the first time, solves high-dimensional variants of a quantum retrodiction puzzle known as the Mean King's Problem. We, therefore, present a case study which investigates the potential for new scientific discoveries through a joint collaboration between human and artificial intelligence.

description: We present ab-initio studies of band offsets, formation energy, and stability of (100) heterojunctions between (Zn,Be)(Se,Te) zincblende compounds, and in particular of the lattice-matched BeTe/ZnSe interface. Equal band offsets are found at Be/Se and Zn/Te abrupt interfaces, as well as at mixed interfaces, in agreement with the established understanding of band offsets at isovalent heterojunctions. Thermodynamical arguments suggest that islands of non-nominal composition may form at the interface, causing offset variations over about 0.8 eV depending on growth conditions. Our findings reconcile recent experiments on BeTe/ZnSe with the accepted theoretical description.

description: This is the third part in a series of papers developing a tensor product theory for modules for a vertex operator algebra. The goal of this theory is to construct a ``vertex tensor category'' structure on the category of modules for a suitable vertex operator algebra. The notion of vertex tensor category is essentially a ``complex analogue'' of the notion of symmetric tensor category, and in fact a vertex tensor category produces a braided tensor category in a natural way. In this paper, we focus on a particular element $P(z)$ of a certain moduli space of three-punctured Riemann spheres; in general, every element of this moduli space will give rise to a notion of tensor product, and one must consider all these notions in order to construct a vertex tensor category. Here we present the fundamental properties of the $P(z)$-tensor product of two modules for a vertex operator algebra. We give two constructions of a $P(z)$-tensor product, using the results, established in Parts I and II of this series, for a certain other element of the moduli space. The definitions and results in Part I (hep-th/9309076, which has been replaced by a new version with a greatly expanded introduction and updated references) and Part II (hep-th/9309159) are recalled.

Peak Effect, Fishtail Effect and Plateau Effect : The Reentrant Amorphization of Vortex Matter in 2H-NbSe_2
Creators: name: al, S. S. Banerjee et
Publisher: name: arXiv
Year: 1999
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The magnetic field dependence of the critical current is studied in single crystal samples of the weak pinning type-II superconductor 2H-NbSe$_2$ in the high temperature and the low field region of the (H,T) phase space, in the vicinity of the reentrant peak effect. The experimental results demonstrate various pinning regimes : a collective pinned quasi-ordered solid in the intermediate field that is destabilized in favor of disordered vortex phases in both high fields near H$_{c2}$ and at low fields near H$_{c1}$. The temperature evolution of the pinning behavior demonstrates how the amorphous limit (where the correlation volume is nearly field independent) is approached around the so-called nose region of the reentrant peak effect boundary. Furthermore, the data show that the rapid approach to the amorphous limit naturally yields a peak effect, i.e., a peak in the critical current, in the high field regime, but yields a ``plateau effect'' instead in the low field regime in an analogous way. With increasing effective disorder the peak effect shifts away from H$_{c2}$ and resembles a ``fishtail'' anomaly.

description: Information Technology (IT) and Information Systems (ISs) compose a critical role in today’s business environment. Enterprise Resource Planning (ERP) systems are the most cutting-edge IS in present business environment. By bringing a company’s different functions together into one large integrated system, an ERP system creates a plethora of opportunities for growth and increased productivity. Medium sized enterprises in the developed world are well ahead in their usage of ERP systems. However, the available studies pertaining to the use of ERP systems in developing countries reveal that, the medium scaled businesses in Sri Lanka are far behind in adaptation of ERP systems. Literature reveals that there are many significant contributing factors that effect selecting and implementation of ERP systems in medium sized organizations in developing countries.  This research is mainly based on qualitative research methodology. Primary data were collected from medium sized industry and their Information Technology (IT) experts though interviews. The objective of using the qualitative research was to find out common and main barriers and their effect to implementation and adaptation of ERPs. Furthermore, secondary data such as Literature was also contributory to the main outcome and results. Influencing factors that analysis research results reveal new way of rationale for selecting and implementation of ERP systems in medium sized companies in developing countries. Results in summary; higher influencing factors in selecting process are Vendor/Software Reputation, Alignment with Business Function, Cost and C-level Officers' countenance. And as this research identifies important factors influencing success of implementation and adaptation of ERPs are Alignment with Business Function, Support and Training, Usability and User friendliness, Implementation Team, Vendor-Employee Interaction and C-level Officers' countenance. In other words this research shows that not only a single IT domain’s factors can influence in success of ERP selection and implementation but also and it is essential to manage modern processes with interdisciplinary comprehension.
Revisiting the Long-Period Transiting Planets from Kepler

description: Currently, we have only limited means to probe the presence of planets at large orbital separations. Foreman-Mackey et al. searched for long-period transiting planets in the Kepler light curves using an automated pipeline. Here, we apply their pipeline, with minor modifications, to a larger sample and use updated stellar parameters from Gaia DR2. The latter boosts the stellar radii for most of the planet candidates found by FM16, invalidating a number of them as false positives. We identify 15 candidates, including two new ones. All have sizes from 0.3 to 1 $R_{\rm J}$, and all but two have periods from 2 to 10 yr. We report two main findings based on this sample. First, the planet occurrence rate for the above size and period ranges is $0.70^{+0.40}_{-0.20}$ planets per Sun-like star, with the frequency of cold Jupiters agreeing with that from radial velocity surveys. Planet occurrence rises with decreasing planet size, roughly describable as $dN/d\log R \propto R^α$ with $α= -1.6^{+1.0}_{-0.9}$, i.e., Neptune-sized planets are some four times more common than Jupiter-sized ones. Second, five out of our 15 candidates orbit stars with known transiting planets at shorter periods, including one with five inner planets. We interpret this high incidence rate to mean: (1) almost all our candidates should be genuine; (2) across a large orbital range (from $\sim 0.05$ to a few astronomical units), mutual inclinations in these systems are at most a few degrees; and (3) large outer planets exist almost exclusively in systems with small inner planets.

description: We study the gravitational wave signal from eight new 3D core-collapse supernova simulations. We show that the signal is dominated by $f$- and $g$-mode oscillations of the protoneutron star and its frequency evolution encodes the contraction rate of the latter, which, in turn, is known to depend on the star's mass, on the equation of state, and on transport properties in warm nuclear matter. A lower-frequency component of the signal, associated with the standing accretion shock instability, is found in only one of our models. Finally, we show that the energy radiated in gravitational waves is proportional to the amount of turbulent energy accreted by the protoneutron star.

description: While the population of the Guatemalan Lake Atitlán basin grows at a rapid pace, the flow of the nutrient phosphorus into the lake has reached a point where eutrophication is imminent again, after already having occurred in 2009 and 2015. This researchs hows which nutrient flows can be adapted to counter balance the current negative nutrient balance. A material flow analysis for the nutrient phosphorus in the boundariesof the Lake Atitlán catchment area was created to this end. The results confirm the negative trend and show where a reduction in the use of phosphorus fertilizer and there placement with livestock manure in agricultural practices, as well as an adapted waste water management system, have an enormous potential to balance out the current trend.

description: The modern world has seen Information Technology being used in most of the business areas. The Enterprise Resource Planning (ERP) systems are typically the largest, most complex, and most challenging information systems implemented by firms, representing a significant departure from the individual and departmental information systems prevalent in the past by integrating the key functions and assisting better and timely decision making.   While many private organizations have successfully taken advantage of these new technologies to develop enterprise-wide information systems that reduce costs and improve performance, however public sectors in most of the developing countries still lags far behind when compared with developed countries. Defence organizations of Sri Lanka, which is one of the largest components of government of Sri Lanka with an annual budget around 200 billion Sri Lankan Rupees, still relies on manual procedures and methods that are error prone and redundant and do not provide the enterprise visibility necessary to make sound management decisions.   Selecting the most suitable ERP product is crucial for the success of ERP implementation. In this study Open Source ERP systems and proprietary ERP systems are critically evaluated in order to determine the best applicability for the defence sector in developing countries.  Transformation of defence organisations in to business entities is the way forward considering the Sri Lankan post war scenario, while achieving to be digital organizations from paper based with emphasis on appropriate product, technology, affordability, flexibility and long term sustainability with the importance multi-disciplinary approach and it will give the necessary efficiency and effectiveness in overall aspects.

description: We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultra metal-poor stars ($\FeH11\Gyr$) and that they are expected to belong to the Milky Way halo, we find that these 42 stars (18 dwarf stars and 24 giants or sub-giants) are currently within $\sim20\kpc$ of the Sun and that they map a wide variety of orbits. A large fraction of those stars remains confined to the inner parts of the halo and was likely formed or accreted early on in the history of the Milky Way, while others have larger apocentres ($>30\kpc$), hinting at later accretion from dwarf galaxies. Of particular interest, we find evidence that a significant fraction of all known UMP stars ($\sim26$\%) are on prograde orbits confined within $3\kpc$ of the Milky Way plane ($J_z < 100 \kms \kpc$). One intriguing interpretation is that these stars belonged to the massive building block(s) of the proto-Milky Way that formed the backbone of the Milky Way disc. Alternatively, they might have formed in the early disc and have been dynamically heated, or have been brought into the Milky Way by one or more accretion events whose orbit was dragged into the plane by dynamical friction before disruption. The combination of the exquisite Gaia DR2 data and surveys of the very metal-poor sky opens an exciting era in which we can trace the very early formation of the Milky Way.
