MATERIAL AND DIMENSIONS. — Maximum height 25.3 mm (incomplete), width 22.6 mm. RGM.1365202 (100+) leg. AWJ; RGM.1365070 (1), leg. AWJ; RGM.1364984 (37), leg. ACJ; RGM.1365088 (82), leg. AWJ; RGM.1365086 (56), leg. WG; RGM.1364914 (28), WG.
SPECIES CHARACTERISATION. — Globular to ellipsoid, thick shell. Short spire with a pointed apex. Juveniles have strong spiral ribs that become obsolete early on the teleoconch. On some specimens the last whorl has at least three brown or red spiral lines. Even though the strength and location of disappearance of spiral ribs is somewhat variable, the overall shape is very distinct.
DISTRIBUTION. — Upper Pliocene: NSB, Red Crag, England (Wood 1848; Harmer 1920; Reid 1996). — Lower Pleistocene: NSB, England (Harmer 1920), Netherlands (Van Regteren Altena et al. 1954; Moerdijk & Janse 2015); Atlantic, Iceland (not in Icelandic modern fauna) (Reid 1996), Selsoif, NW France (this paper). — Middle Pleistocene: Channel region England (Preece & Bates 1999). — Upper Pleistocene: NSB, England (Harmer 1920). Recent distribution in the western Atlantic from Newfoundland to Chesapeake Bay in the western Atlantic (Reid 1996), in the eastern Atlantic from the White Sea southwards, occasionally as far as southern Portugal. The lack of fossil occurrences in the western Atlantic allows the possibility that the species was introduced there by e.g., Vikings (Reid 1996).

description: In a class of $E_6$ inspired models with a light additional neutral vector boson, we discuss the effects of the magnetic moment of the tau neutrino by analyzing $e^{+}e^{-}$ $\to $ $γν\barν$ at the $Z$-pole. We take into account present scenarios for the extra Abelian group and vary extra neutral gauge boson mass beyond the present experimental exclusion limits. The present LEP experimental results prove us to set an upper bound on the magnetic moment of the tau neutrino: $κ_{ν_τ}$ $ \leq $ 1.83*10$^{-6}$ .

description: Point defects exist widely in engineering materials and are known to scatter vibrational modes to reduce thermal conductivity. The Klemens description of point defect scattering is the most prolific analytical model for this effect. This work reviews the essential physics of the model and compares its predictions to first principles results for isotope and alloy scattering, demonstrating the model as a useful materials design metric. A treatment of the scattering parameter ($Γ$) for a multiatomic lattice is recommended and compared to other treatments presented in literature, which have been at times misused to yield incomplete conclusions about the system's scattering mechanisms. Additionally, we demonstrate a reduced sensitivity of the model to the full phonon dispersion and discuss its origin. Finally, a simplified treatment of scattering in alloy systems with vacancies and interstitial defects is demonstrated to suitably describe the potent scattering strength of these off-stoichiometric defects.

description: A discounted net cash flow (NCF) model incorporating Monte Carlo simulation was developed to quantify the net benefits and risks of growing the new red-blushed pear cultivar ‘ANP-0131’ (Deliza®) on a representative orchard block in Victoria’s Goulburn Valley. Results were compared to those for retaining a traditional low-density (343 trees/ha) planting of ‘Packham’s Triumph’. ‘ANP-0131’ was grafted to Quince A rootstock and trained on Open Tatura trellis at densities of 1,481, 2,222 or 4,444 trees/ha; these are three of the training system x rootstocks x tree spacing combinations currently being investigated at Agriculture Victoria’s experimental orchard in Tatura. The trees in the experimental orchard are currently in their fifth year of a potential life-span of 30 years and have been fruiting for the last three years. Hence, the analysis is prospective and based on crucial assumptions concerning pack-outs, prices and yields. From 10,000 simulations it was found that growers could invest in the new ‘ANP-0131’ pear system with confidence. Subject to the law of diminishing returns, the most profitable planting was 2,222 trees/ha, for which the mean Net Present Value (NPV) was $258,471/ha evaluated over 30 years using a discount rate of 4.5% real. The Modified Internal Rate of Return (MIRR) was 10.9 per cent, beating the real nine per cent return on Australian equities. The payback period ranged from 7 to 11 years from best to worst case scenarios. The relative advantage of the new planting over the existing planting of ‘Packham’s Triumph’ was clear; the mean annuity of the NPV for the new planting was $15,835/ha p.a., the NCF for the existing planting was a modest $4,595/ha p.a. and there was a 20 per cent chance that it would lose money in any one year.

description: Molecular chirality, and the chiral symmetry breaking of resulting macroscopic phases, can be topologically imprinted and manipulated by crosslinking and swelling of polymer networks. We present a new experimental approach to stereo-specific separation of chiral isomers by using a cholesteric elastomer in which a helical director distribution has been topological imprinted by crosslinking. This makes the material unusual in that is has a strong phase chirality, but no molecular chirality at all; we study the nature and parameters controlling the twist-untwist transition. Adding a racemic mixture to the imprinted network results in selective swelling by only the component of ``correct'' handedness. We investigate the capacity of demixing in a racemic environment, which depends on network parameters and the underlying nematic order.
Building a data archive that meets the needs of both researchers and non-researchers: how CPANDA addresses this challenge
Creators: name: McGill, Larry
Publisher: name: Zenodo
Year: 2005

description: The Cultural Policy the Arts National Data Archive (CPANDA) at Princeton University was created in 2003 to stimulate the development of a nascent field of study - arts and cultural policy research. As a field-building enterprise, CPANDA seeks not only to archive relevant data sets, but also to spur new research, encourage emerging scholars to take an interest in the field, and inform journalists, policy makers, artists, cultural organizations, and the public about the data it collects. Meeting the needs of such a diverse set of potential users poses significant challenges for organizing and creating web content, building tools for accessing data, and educating non-researchers on the proper interpretation of statistical data. At the same time, CPANDA must also meet the needs of its primary constituency, the research community; it is, after all, a data archive. This presentation will discuss how CPANDA structures users' online experience so as to meet the data and information needs of individuals with widely differing backgrounds and research expertise.

cf. Turbo cancellatus da Costa, 1778: 104, pl. 8, figs 6, 8.
MATERIAL AND DIMENSIONS. — Maximum height 2.6 mm, width 1.6 mm. — RGM.1364986 (1), leg. ACJ; RGM.1310338 (1), leg ACJ.
SPECIES CHARACTERISATION. — Shell small, rissoiform. Protoconch not preserved. Three teleoconch whorls preserved. Sculpture of three spiral cords on spire whorls, and 13 orthocline ribs forming coarsely reticulated sculpture. Last whorl bearing six spiral cords. Aperture round, peristome complete, thickened, outer lip thickened.
DISTRIBUTION. — Lower Pleistocene: Atlantic, Selsoif,NW France (this paper). Alvania cancellata is known from the Upper Pliocene Atlantic of the Mondego Basin, Portugal, and was widespread in the Pliocene Mediterranean. Raad et al. (2013) reported occasional findings from the Upper Pleistocene NSB of the Netherlands.Today it is distributed from the British Isles south into the Mediterranean (Landau et al. 2004).
REMARK
Due to the scarcity and poor preservation of the material at hand, identification is uncertain. It is clearly separated from the other two congeners present in the assemblage by the shape and the number of spiral cords.

description: Formalism based on equilibrium statistical thermodynamics is applied to communication networks of decision making individuals. It is shown that in statistical ensembles for choice models, properly defined disutility can play the same role as energy in statistical mechanics. We demonstrate additivity and extensivity of disutility and build three types of equilibrium statistical ensembles: the canonical, the grand canonical and the super-canonical. Using Boltzmann-like probability measure one reproduce the logit choice model. We also propose using q-distributions for temperature evolution of moments of stochastic variables. The formalism is applied to three network topologies of different degrees of symmetry, for which in many cases analytic results are obtained and numerical simulations are performed for all of them. Possible applications of the model to airline networks and its usefulness for practical support of economic decisions is pointed out.

description: We analize the use of algorithms based in x-space for the solution of renormalization group equations of DGLAP-type and test their consistency by studying bounds among partons distributions - in our specific case Soffer's inequality and the perturbative behaviour of the nucleon tensor charge - to next-to-leading order in QCD . A discussion of the perturbative resummation implicit in these expansions using Mellin moments is included. We also comment on the (kinetic) proof of positivity of the evolution of $h_1$, using a kinetic analogy and illustrate the extension of the algorithm to the evolution of generalized parton distributions. We prove positivity of the non-forward evolution in a special case and illustrate a Fokker-Planck approximation to it.

description: At Moriond 2019, Belle collaboration has announced new measurements on the flavour ratios $R_D - R_{D^*}$ which are consistent with their Standard Model predictions within $1.2σ$. After inclusion of these measurements, the global tension in $R_D - R_{D^*}$ has reduced from $4.1σ$ to $3.1σ$ which is still significant. The measurements of these ratios indicate towards the violation of lepton flavor universality in $b\rightarrow c\,l\,\barν$ decay. Assuming new physics in $b\rightarrow c\,τ\,\barν$ transition, we have done a global fit to all available data in this sector to identify the allowed new physics solutions. We find that there are seven allowed new physics solutions which can account for all measurements in $b\rightarrow c\,τ\,\barν$ transition. We show that a simultaneous measurement of the $τ$ polarization fraction and forward-backward asymmetry in $B\rightarrow D\,τ\,\barν$, the zero crossing point of forward backward asymmetry in $B\rightarrow D^*τ\barν$ and the branching ratio of $B_c\rightarrow τ\,\barν$ decay can distinguish these seven new physics solutions if they can be measured with a required precision.

description: Dairying is an important component of Pakistan’s mixed crop-livestock farming systems. The national economy engages some 8.8 million small-scale producer households. The country produces more milk than any other except for the United States and India. Yet little is known about small-scale producer microeconomics to inform policy development for improving their welfare. In this paper we aim to identify the whole farm profitability of small agricultural households, with a specific focus on milk production. We compare two contrasting agro-ecological regions within Pakistan’s Punjab (irrigated Okara and rain-fed Bhakkar) using results for a single 2008-09 fiscal year of production for 212 farms. Net farm profits, taking long-run opportunity costs of labour and capital into account, showed only 10 per cent of these farms to be profitable in either district, though short-run profits, accounting for cash costs only, showed positive whole farm gross margins for 90 per cent and 80 per cent of farms in Okara and Bhakkar, respectively. The returns on assets (at 2.78 per cent and 0.53 per cent for the two districts) was lower than the national average return on savings (9 per cent). For dairy enterprises, total costs were higher than incomes; so many farms (70 per cent and 60 per cent, respectively) were assessed as making losses. Given the low opportunity costs of feeds (often crop residues) and of labour (6.2 per cent unemployment) and the high rate of inflation (11.8 per cent), returns on factors of production including labour and capital, may not be lower than international standards. There is a need, however, to raise the dairy industry’s overall productivity to make dairying viable; and to identify an optimal land and livestock combination that is profitable and commercially viable.
New user needs will change 'best practice' of data archive services

Publisher: name: Zenodo

description: Slovene Social Science Data archive is relatively young archive and was for that reason able to follow "best practices" of established archives. Never the less, use and usability of offered services is changing with new technologies and that is why practice, that was once very good, needs to be changing as well. Regular users of data archive services have different needs than new users. Decision was made to interview both groups of users to find out first how to improve ADP work and services provided (e.g. improving accessibility of information on a web page) and second, to find out for what purposes are data and documentation mostly used - to find the most common user group to target. At the same time we provided information about services that ADP offers and metadata information about surveys that are available. Our experience is that part of provided information is rarely used, because users had no knowledge of its existence or practicability. Gathered information will be used to help plan future services and to prepare seminars for target groups.
Phase chirality and stereo-selective swelling of cholesteric elastomers

description: Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter. This parameter can be tuned by changing the helix pitch p and/or the elastic properties of the network. The cholesterics also possess a local nematic order, changing with temperature or during solvent swelling. In this paper, by measuring the power of optical rotation, we discover how these two parameters vary as functions of temperature or solvent adsorbed by the network. The main result is a finding of pronounced stereo-selectivity of cholesteric elastomers, demonstrating itself in the retention of the ``correct'' chirality component of a racemic solvent. It has been possible to quantify the amount of such stereo-separation, as the basic dynamics of the effect.

Year: 2020
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Large planetary spin-orbit misalignments (obliquities) may strongly influence atmospheric circulation and tidal heating in the planet. A promising avenue to generate obliquities is via spin-orbit resonances, where the spin and orbital precession frequencies of the planet cross each other as the system evolves in time. One such mechanism involves a dissipating (mass-losing) protoplanetary disk that drives orbital precession of an interior planet. We study this scenario analytically in this paper, and obtain the mapping between the general initial spin orientation and the final obliquity. We show that (i) under adiabatic evolution (i.e. the disk dissipates at a sufficiently slow rate), the final planetary obliquity as a function of the initial spin orientation bifurcates into distinct tracks governed by interactions with the resonance; (ii) under nonadiabatic evolution, a broad range of obliquities can be excited. We obtain analytical expressions for the final obliquities for various regimes of parameter space. The dynamical system studied in this paper is an example of "Colombo's top", and our analysis and results can be adapted to other applications.

description: Although controlled traffic farming (CTF) has been shown to provide production, environmental and economic benefits in a number of cropping industries, uptake in vegetable production is limited. In many situations adoption is constrained by the lack of harvest equipment suited to CTF. Research shows there are important soil benefits, and potential yield improvements, to be gained from CTF in vegetable production. With little on-ground experience to provide economic data, a model was developed to determine the difference in returns between three different vegetable farming systems. Returns were calculated as income minus operating and ownership costs (including interest and depreciation). Case study farms were used as data sources, and despite using very conservative estimates of the production and management changes likely to occur under CTF, modelling indicated median increases in average returns of up to 29%. These results were obtained even when the costs of meeting harvest integration were taken into account, indicating that the benefits of controlled traffic in vegetable production should adequately cover the costs of transition.

description: In this collective article, members of the AnonymClassic project discuss various aspects of their work on the textual tradition Kalīla and Dimna. Beatrice Gruendler provides a general introduction to the questions being considered. This is followed by a number of short essays in specific areas, organized into three categories: codicology, literary history and theory, and the digital infrastructure of the project. Jan J. van Ginkel summarizes the challenges involved in editing the Syriac versions of Kalīla and Dimna; Rima Redwan explains the AnonymClassic team’s approach vis-à-vis the transcription and textual segmentation of Arabic manuscripts; Khouloud Khalfallah follows this with an overview of the types of data that are recorded for each codex that is integrated into the project; Beatrice Gruendler, in a second contribution, shares some preliminary results from the analysis of interrelationships among manuscripts; and Rima Redwan, also in a second contribution, discusses the sets of illustrations, or »image cycles«, that are found in many copies of Kalīla wa-Dimna. Moving into the realm of literary history and theory, Isabel Toral poses a range of questions relating to the status of Kalīla and Dimna, as (arguably) anonymous in authorship and as a fundamentally translated book; Johannes Stephan explores the references to Kalīla wa-Dimna found in various medieval Arabic scholarly works; and Matthew L. Keegan confronts the problem of the genre(s) to which Kalīla wa-Dimna might be assigned and the exceptional »promiscuity« of the text. The last section of the article, on digital infrastructure, contains two contributions: Theodore S. Beers describes a web application that the team has created to facilitate the consultation of published versions of Kalīla and Dimna, and, finally, Mahmoud Kozae and Marwa M. Ahmed offer a more comprehensive discussion of the digital tools and methods – specialized and in some cases developed »in-house« – on which the AnonymClassic project relies.

description: Using ultrafast pump-probe reflectivity with 3.1 eV pump and coherent white light probe (1.1 to 2.6 eV), we show that graphene on gold nanostructures exhibits a strong coupling to the plasmonic resonances of the ordered lattice hole array, thus injecting a high density of hot carriers in graphene through plasmons. The system being studied is single-layer graphene on ultrathin film of gold with periodic arrangements of holes showing anomalous transmission. A comparison is made with gold film with and without hole array. By selectively probing transient carrier dynamics in the spectral regions corresponding to plasmonic resonances, we show efficient plasmon-induced hot carrier generation in graphene. We also show that due to high electromagnetic field intensities at the edge of the sub-micron holes, fast decay time (10-100 fs) and short decay length (1 nm) of plasmons, a highly confined density of hot carriers (very close to edge of the holes) is generated by Landau damping of plasmons within the holey gold film. A contribution to transient decay dynamics due to diffusion of initial non-uniform distribution of hot carriers away from the hole edges is observed. Our results are important for future applications of novel hot carrier device concepts where hot carriers with tunable energy can be generated in different graphene regions connected seamlessly.

description: The Australian Centre for Agricultural Health and Safety established a longitudinal study of 335 NSW farm enterprises to derive data on farm health and safety management and how it relates to farmer perceptions. The analysis reported in this paper benchmarked the perceptions of the study informants on the role and importance of health and safety on their farms and reviewed the safety performance of the study enterprises, focusing on management of safety systems and processes and control of major risks and hazards on their farms. The results not only challenged some apparent misconceptions, such as older farmers having more negative attitudes towards farm safety than younger farmers, but it also identified industries from within the study population that are performing well in the management of safety and the possible reasons behind their success. Importantly, it also observed an area of disconnect between having a positive attitude towards farm safety and its role and importance, and actually implementing farm safety systems and management processes on the farm. These findings provide evidence for the possible benefits of tailoring farm initiatives and interventions based on gender, age and industry. Set beside other analyses of the changes farmers had made on their farms, the prompts and drivers for making those changes, and the issues and risks that the farmers see as important on their own farms, a wealth of information is available to health and safety researchers, Farmsafe Australia, work safety authorities and industry bodies to direct and prioritise their research programs and policy initiatives.

description: The characteristics of an imaging system formed by a left-handed material (LHM) slab of finite length are studied, and the influence of the finite length of the slab on the image quality is analyzed. Unusual phenomena such as surface bright spots and negative energy stream at the image side are observed and explained as the cavity effects of surface plasmons excited by the evanescent components of the incident field. For a thin LHM slab, the cavity effects are found rather sensitive to the length of the slab, and the bright spots on the bottom surface of the slab may stretch to the image plane and degrade the image quality.

description: We study the topological phase in dipolar-coupled two-dimensional breathing square lattice of magnetic vortices. By evaluating the quantized Chern number and $\mathbb{Z}_{4}$ Berry phase, we obtain the phase diagram and identify that the second-order topological corner states appear only when the ratio of alternating bond lengths goes beyond a critical value. Interestingly, we uncover three corner states at different frequencies ranging from sub GHz to tens of GHz by solving the generalized Thiele's equation, which has no counterpart in condensed matter system. We show that the emerging corner states are topologically protected by a generalized chiral symmetry of the quadripartite lattice, leading to particular robustness against disorder and defects. Full micromagnetic simulations confirm theoretical predictions with a great agreement. A vortex-based imaging device is designed as a demonstration of the real-world application of the second-order magnetic topological insulator. Our findings provide a route for realizing symmetry-protected multi-band corner states that are promising to achieve spintronic higher-order topological devices.

description: Citizen science methodologies have over the past decade been applied with great success to help solve highly complex numerical challenges. Here, we take early steps in the quantum physics arena by introducing a citizen science game, Quantum Moves 2, and compare the performance of different optimization methods across three different quantum optimal control problems of varying difficulty. Inside the game, players can apply a gradient-based algorithm (running locally on their device) to optimize their solutions and we find that these results perform roughly on par with the best of the tested standard optimization methods performed on a computer cluster. In addition, cluster-optimized player seeds was the only method to exhibit roughly optimal performance across all three challenges. This highlights the potential for crowdsourcing the solution of future quantum research problems.

description: Variable rate nutrient application (VRA) has the potential to improve farm profitability by improving the overall use of fertiliser inputs on-farm. In addition, VRA nutrient application is potentially a viable option for the reduction of dissolved inorganic nitrogen (DIN) in farm water runoff as a consequence of the associated reduction in overall nitrogen application. Agricultural runoff, in particular DIN from sugarcane production in the Mackay Whitsunday region, enters into the Great Barrier Reef lagoon affecting water quality. In this study we investigate the impact on the economics of the farm business due to a shift from the conventional sugarcane farming practice, using the industry’s ‘Six Easy Steps’ (6ES) nutrient application rate, to variable rate within block. The conventional 6ES rate is based on the district yield potential in conjunction with the soil mineralisation index and organic carbon content of soils on a particular block in a given region. VRA of nutrients aims to match the nutrient application rate to the historical block yield potential and the physical and chemical properties of the soil. Where there is significant variation within-block in terms of yield or crop variation, topography, climate and soil characteristics, nutrients can be varied to match zone yield targets. We find that the VRA system has the capacity to improve farm gross margins and reduce the overall nutrient application on one trial farm (by 14 percent). However, after the capital outlay required for the system was accounted for, we find that the VRA system reduced the profitability of the overall farming enterprise. Consequently, we explore the conditions under which the VRA system adds value to the trial farm, and also the minimum farm size (on land with similar yield variation to the trial property) needed for the capital outlay to breakeven.

description: A dark soliton oscillating in an elongated harmonically-confined atomic Bose-Einstein condensate continuously exchanges energy with the sound field. Periodic optical `paddles' are employed to controllably enhance the sound density and transfer energy to the soliton, analogous to parametric driving. In the absence of damping, the amplitude of the soliton oscillations can be dramatically reduced, whereas with damping, a driven soliton equilibrates as a stable dark soliton with lower energy, thereby extending the soliton lifetime up to the lifetime of the condensate.

description: In der vorliegenden Arbeit wurden experimentelle, physikalisch-technische und translationale Entwicklungen der DBS zur Behandlung von Bewegungsstörungen beschrieben. In einer tierexperimentellen Studie konnten wir zeigen, dass die DBS neben den bekannten unmittelbaren Effekten auf Motorsymptome ein neuromodulatives und neuroprotektives Potential in sich trägt, welches möglicherweise über die Beeinflussung von neurotrophen Faktoren vermittelt wird. Die Ergebnisse dieser Studie geben Anhalt zu der Annahme, dass die DBS zukünftig in einer Reihe weiterer neurodegenerativer Erkrankungen wirksam krankheitsmodulierend eingesetzt werden könnte. In einer zweiten bildgebenden Studie wurde verdeutlicht, dass im Zuge jüngster Verbesserungen in der MRT Auflösung heute morphometrische Merkmale erkrankter Gehirne erkennbar geworden sind, die möglicherweise Rückschlüsse auf die jeweilige Krankheitspathogenese zulassen. So konnten wir in einer Kohorte von Dystonie-PatientInnen Volumenveränderungen der Basalganglien und Signalalterationen beschreiben, die Hinweise auf regionale Überaktivität und Degeneration geben. Eine dritte Studie zur Einführung eines intraoperativen Computertomographen verdeutlicht, wie technische und strukturelle Weiterentwicklungen zur Beschleunigung und Rationalisierung intraoperativer Abläufe in der stereotaktischen Chirurgie geführt haben. In den letzten beiden Publikationen zu den Impulsgebern zeigten wir auf, dass das IPG-Nachfolgermodell des gegenwärtigen Marktführers eine kürzere Batterielaufzeit aufweist als das Vorläufermodell, und legten technische Parameter dar, die die Batterielaufzeit beeinflussen. Die Verkürzung der IPG-Lebensdauer hatte sowohl für die behandelten PatientInnen, als auch für unser Gesundheitssystem erhebliche Nachteile zur Folge gehabt. Hier wurde die Abhängigkeit der funktionellen Neurochirurgie von industrieller Entwicklung und Produktion deutlich. Die hier vorgelegten Arbeiten stehen beispielhaft für die rasanten technischen Entwicklungen der DBS über das vergangene Jahrzehnt und weisen ferner darauf hin, dass die Technik neben dem therapeutischen Nutzen ein ungeahntes Potential, weitere Einblicke in die Elektrophysiologie und die funktionelle Vernetzung des Gehirns zu erhalten, in sich birgt.
