description: A microscopic theory for rare-earth ferromagnetic hexaborides, such as Eu(1-x)Ca(x)B6, is proposed on the basis of the double-exchange Hamiltonian. In these systems, the reduced carrier concentrations place the Fermi level near the mobility edge, introduced in the spectral density by the disordered spin background. We show that the transport properties such as Hall effect, magnetoresitance, frequency dependent conductivity, and DC resistivity can be quantitatively described within the model. We also make specific predictions for the behavior of the Curie temperature, Tc, as a function of the plasma frequency, omega_p.

description: We give exact results for the emission spectra of both nonlinear Breit-Wheeler pair production and nonlinear Compton scattering in ultra-intense, ultra-short duration plane wave backgrounds, modelled as delta-function pulses. This includes closed form expressions for total scattering probabilities. We show explicitly that these probabilities do not exhibit the power-law scaling with intensity associated with the conjectured breakdown of (Furry picture) perturbation theory, instead scaling logarithmically in the high-intensity limit.

title: Inventing (Post)Memory, Writing (Non)Fiction: Jerzy Kosinski, Philip Roth and the Legacy of World War II
Creators: name: Simonetti, Paolo
Publisher: name: Status Quaestionis
Year: 2020

description: In this essay, I argue that Marianne Hirsch’s definition of postmemory might be extended to hybrid forms of autobiographical writing such as the fraudulent survivor’s autobiography and the counterfactual or uchronic memoir. To that effect, the essay deals with Jerzy Kosinski’s controversial first novel The Painted Bird (1965) and Philip Roth’s uchronia The Plot Against America (2004) as peculiar types of postmemorial works. Though both writers experienced the war during their childhood and their texts were written at a great remove from the war-period, these works can be considered World War II novels since they register and represent the war as a central, traumatic event. Kosinski’s and Roth’s recollections of the wartime period in their novels are so distorted, manipulated, and fictionally imagined (if not utterly invented) that they share the same “oscillation between continuity and rupture” typical of the postmemorial narratives described by Hirsch.

description: The on-farm diversification toward multifunctional activities is perceived as central in the CAP policy reform and in Horizon 2020 strategies, because it strengthen territorial and social cohesion of the rural areas. While relations between farm-household diversification and rural economies are central into the process of multifunctionality and provision of public goods through agricultural activities, on-farm diversification activities could represent a relevant share of farm income. Agricultural Economics and Rural Sociology literatures have developed models to explain the determinants of on-farm diversification. In this paper the determinants and the motivations to onfarm diversification toward activities different from crops and animal production are investigated The paper applies a count model to explain the amount of on-farm diversification alternatives that are applied in Tuscany farms. Results confirm that location to main touristic areas and closeness to urban markets are strong determinants of on-farm diversification. Results highlight also, a positive contribution of agricultural policies (both first pillar and second pillar policies) in determining diffusion of on-farm diversification activities.

description: Externally designed strategies for improving the farm enterprise and reduce poverty among rural households may not produce desired results. For farm households to adopt economic approaches such as record keeping and management, innovative approaches that are participatory and which build on their indigenous knowledge are better. The value of farm level record keeping has been known for many decades now, yet many farmers in developing countries do not keep records. This paper presents the outcome of using innovative approaches that involved a rural community in a rural Ghanaian community. This research used consultation, village level meetings and participatory approaches to design user-friendly systems. This resulted in systems with which they can cope and which continued after the programme was over. There is the need to improve rural livelihoods by building on indigenous knowledge and using approaches that achieve greater productivity, efficiency, equity, profitability and sustainability. The findings show that rural households are knowledgeable and have the ability to decide on data collection formats that suit their needs.

description: We solve the following problem: to describe in geometric terms all differential operators of the second order with a given principal symbol. Initially the operators act on scalar functions. Operator pencils acting on densities of arbitrary weights appear naturally in the course of study. We show that for the algebra of densities it is possible to establish a one-to-one correspondence between operators and brackets generated by them. Everything is applicable to supermanifolds as well as to usual manifolds. In the super case the problem is closely connected with the geometry of the Batalin--Vilkovisky formalism in quantum field theory, namely the description of the generating operators for an odd bracket. We give a complete answer. This text is a concise outline of the main results. A detailed exposition is in \texttt{arXiv:math.DG/0212311}.

description: When data are collected subject to a detection limit, observations below the detection limit may be considered censored. In addition, the domain of such observations may be restricted; for example, values may be required to be non-negative. We propose a regression method for censored observations that also accounts for domain restriction. The method finds maximum likelihood estimates assuming an underlying truncated normal distribution. We show that our method, tcensReg, outperforms other methods commonly used for data with detection limits such as Tobit regression and single imputation of the detection limit or half detection limit with respect to bias and mean squared error under a range of simulation settings. We apply our method to analyze vision quality data collected from ophthalmology clinical trials comparing different types of intraocular lenses implanted during cataract surgery.

description: In 2001, Lincoln University and six commercial, education and research partners established a 161 hectare dairy farm (milking platform) and formed the South Island Dairy Development Centre (SIDDC) to demonstrate ‘best practice’ for South Island dairy farmers. In 2008, to assess the impact of the Lincoln University Dairy Farm (LUDF), a survey was sent to 622 farmers located in the LUDF extension catchment. Responses totalled 146 (24% response rate). The mean age of respondents was 45 years with 77% having some form of tertiary education. Respondents had higher milksolids production per cow (419 kg) and per hectare (1441 kg) than the Canterbury averages (381kg and 1224kg respectively). Most respondents (86%) identified themselves as using moderate levels of supplementary feeding (Systems 2, 3, 4). Nearly 70% of respondents attended at least one focus day (field day) over a three year period. Most attended to learn about grazing and animal management, to benchmark against the LUDF from a production and financial standpoint, and to learn about environmental management. Focus day attendees had larger operations and higher levels of productivity than those who never attended. Over 68% of respondents visited the farm website each year, with some visiting more than 30 times, but mainly to view benchmarking data rather than to learn about new technologies Of the technologies promoted by the LUDF, 82% of farmers had adopted low grazing residuals and 74% had re-grassed paddocks based on monitoring. Lower numbers had adopted synchronisation of heifers to calve a week before the main herd (29%), aggressive hormone intervention for non-cycling (42%) and a nil induction policy (36%). Over 70% felt that the adoption of some of the LUDF technologies had made their farm management easier. Twenty three farmers were willing to place an economic value on the adoption of LUDF practices. These ranged from NZ$50,000 per year to NZ$1,000,000 per year. It is concluded that a demonstration farm with clearly defined extension messages can be effective at achieving farmer adoption that adoption is high for messages where farmers see clear economic advantages, and that farmers obtain information from a wide variety of sources.

description: Solvability of the conjugacy problem for relatively hyperbolic groups was announced by Gromov [Hyperbolic groups, MSRI publications 8 (1987)]. Using the definition of Farb of a relatively hyperbolic group in the strong sense [B Farb, Relatively hyperbolic groups, Geom. Func. Anal. 8 (1998) 810-840], we prove this assertion. We conclude that the conjugacy problem is solvable for fundamental groups of complete, finite-volume, negatively curved manifolds, and for finitely generated fully residually free groups.

description: The present paper represents a continuation of our previous one. There, a continuous dependence result for the solution of an elliptic variational-hemivariational inequality was obtained and then used to prove the existence of optimal pairs for two associated optimal control problems. In the current paper we complete this study with more general results. Indeed, we prove the continuous dependence of the solution with respect to a parameter which appears in all the data of the problem, including the set of constraints, the nonlinear operator and the two functionals which govern the variational-hemivariational inequality. This allows us to consider a general associated optimal control problem for which we prove the existence of optimal pairs, together with a new convergence result. The mathematical tools developed in this paper are useful in the analysis and control of a large class of boundary value problems which, in a weak formulation, lead to elliptic variational-hemivariational inequalities. To provide an example, we illustrate our results in the study of an inequality which describes the equilibrium of an elastic body in frictional contact with a foundation made of a rigid body covered by a layer of soft material.

description: A substantial literature has addressed the many issues relevant to describe, analyse and assess the question of income distribution and its role vis-­‐a-­‐vis economic growth and its sustainability, as well as concerns about poverty and social exclusion in particular when age and gender related. Undoubtedly, building on the EU-­‐SILC information, a much scarcer attention has been paid to the agricultural sector and the rural environment. This paper aims at offering a contribution to fill this gap by presenting some reflections based on empirical data. Although putting forward the entire range of the results obtained defies the space limits posed by a paper, the focus of this contribute is directed to compare the agricultural incomes in two points in time: in 2006 before the Great Recession flared up and in 2011, at the most recent date available today, when the crisis is not yet over. It is, of course, hard to prove that, having compared incomes in the agricultural sector as well as in the rural areas across countries and for two reference years, the observed outcome is certainly due to the financial crisis. Being concerned with the effects following the financial crisis, the analysis looks in particular at those countries belonging to the Euro area and present in the survey at the earliest date. A more even platform across countries permits to better concentrate on the best survivors in the farm sector: those who seem to have suffered less offer a sure example of resilience. Indeed, we do not dare adventuring in any cause-­‐effect relationship. We believe that the very comparison can provide some food for thought and somewhat new elements to be fruitfully added to the discussion.
Economics of film antitranspirant application: a new approach to protecting wheat crops from drought-induced yield loss

description: Drought is a major cause of economic loss to the world’s wheat growers; estimated at up to US$20 billion (£12.5 bn) in 2000. Film antitranspirants are polymers applied to foliage to reduce water loss and have recently been shown to increase droughted wheat yield. This increase is linearly related to the drought severity (soil moisture deficit [SMD]) at the time of application. This paper demonstrates how this linear relationship can be used to calculate an economic threshold SMD, above which an economic yield response should be obtained, from spray cost and expected grain price. This will enable agronomists and growers to make a clear decision on the cost-effectiveness of spraying to protect from drought damage. Sensitivity analysis shows that using the correct spray decision threshold SMD is especially important when the wheat grain price is expected to be low.
Predicting determinants of UK dairy farmers' behavioural intention to use blockchain applications for sustainable supply chain
Creators: name: Ayodele, Julius Oluwasunkanmi
Publisher: name: Zenodo
Year: 2024

description: This thesis addresses the need for improved technology adoption in the UK dairy industry.It suggests that blockchain technology would dramatically improve the supply chain andaddress industry difficulties and issues like the traceability of milk and environmentalconcerns. This work critically assesses the impact of technology acceptance determinantson UK dairy farmers’ behavioural intention to use blockchain technology applications fora sustainable supply chain. Relevant industry reports and related literature are reviewed,including examplesfrom overseas. A range of theories are applied to this context, includingthe diffusion of innovation theory, the technology acceptance model, and the unified theoryof acceptance and use of technology. Their relevance and application are investigated bysurveying UK dairy farmers. The quantitative research approach produced results that wereanalysed using SPSS version 25, showing that there is a low awareness of blockchaintechnology among UK dairy farmers. The Partial Least Squares Structural EquationModelling (PLS-SEM) on the SmartPLS 3.0 shows that technology acceptancedeterminants, including social influence, perceived ease of use, and perceived usefulness,influenced UK dairy farmers' behavioural intentions to use blockchain technologyapplications for a sustainable supply chain. Trust shows a non-insignificant influence,while the facilitating condition did not satisfy the convergent validity of 0.50 (50%). Theinvestigation concludes that blockchain adoption can transform the UK dairy industry.Significant technology acceptance determinants are recommended for designing andimplementing consortium blockchain technology in the UK dairy industry. This researchcontributes to blockchain adoption for enhancing conventional dairy supply chains throughtechnology acceptance determinants.
Green Economy and Bio-based Economics: Assessment and Critique of Their Philosophical Assumptions

subject: liberalism/neoliberalism

description: The paper aims at establishing a philosophical comparison between the notion of green economy and the concept of bio-based economics. Against the background of the current, devastating economic crisis, they both represent an attempt to overcome a growth impasse through the incorporation of the environmental limit as a new terrain for accumulation and valorization. Otherwise put, both green economy and bio-based economics assume that economic growth and environmental preservation not only are not contradictory, but can actually set in motion – through the discursive formation of sustainability – a virtuous circle in which the increase of one element fosters a parallel increase of the other. The analysis of such an affinity will be historically analyzed by referring to Michel Foucault's biopolitical analyses. Subsequently, the crucial notion of bio-mimicry will be theoretically approached, as will the dangers embodied in the currently under way process of economization of nature. The argument is that by modelling nature according to industrial needs or competitive frameworks a crucial risk emerges: the possibility of tackling an undeniable environmental crisis by deepening an already unjust social polarization. By contrast, a public goods or common-based perspective would provide a theoretical background for tackling the social, economic and ecological crises simultaneously. For such a background to emerge, however, market competitiveness as well as sacred property rights regimes should be substituted by common cooperation and sharing-cultures.

A polarization Sagnac interferometer with an embedded 45$^{\circ}$-oriented dove prism is used to enable the polarization control qubit to act on the momentum (spatial) target qubit of the same photon. The CNOT gate requires no active stabilization because the two spatial modes share a common path, and it is used to entangle the polarization and momentum qubits.

Rotation curves of spiral galaxies: A general-relativistic model

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Spiral galaxies are considered as static, spherically symmetric Dark Matter Configurations (DMC)in which non-zero rest-mass particles (NZRPs) move along appropriate trajectories. Using general relativity (GR), we show that a mass of dark matter about 127 - 212 $\times 10^{11} M_{\odot}$ is required inside the sphere of size $a \sim 10 $ kpc for agreement with the observed typical orbital velocity ranging from 150 to 250 km sec$^{-1}$. In our model, it is possible to obtain flat, slightly rising, and even declining rotation curves. The model self-evidently explains the reason why most of the spirals show almost flat or slightly rising rotation curves and very few show declining curves. The NZRPs follow trajectories, and are finally trapped in circles of minimum radii $\sim 0.03a - 0.005a$ with rotation velocities reaching $\sim 6544-8445$ km sec $^{-1}$. The velocity values are consistent with observations of central regions of various galaxies. This scenario may also lead to conditions suitable for evolution of relativistic supermassive stars and supermassive black holes at the centres of various galaxies. Based on this study, we obtain the density parameter $Ω\sim 0.127 - 0.212 $, leading to an open model of the Universe with an age of $\sim 16.8 - 17.6 $ Gyr, which is significantly higher than the presently estimated age of globular clusters $\sim 13 - 15 $ Gyr.

description: In low potential agricultural areas like the Honduran hillsides characterized by soil degradation and erosion, organic agriculture can provide a means to break the downward spiral of resource degradation and poverty. We use original survey data to analyze the factors influencing the decision to convert to organic agriculture. Previous studies have emphasized the role of spatial patterns in the diffusion and adoption of agricultural technologies in general and organic agriculture in particular. These spatial patterns can result from a variety of underlying factors. In this article we test various potential explanations, including the availability of information in the farmer's neighborhood, social conformity concerns and perceived positive external effects of the adoption decision, in a spatially explicit adoption model. We find that farmers who believe to act in accordance with their neighbors' expectations and with greater availability of information in their neighborhood network are more likely to adopt organic agriculture. Furthermore, perceived positive productivity spillovers to neighboring plots decrease the probability of adoption. We discuss the implications of our findings for the dissemination of sustainable agricultural technologies in low-potential agricultural areas in developing countries.

description: Using a population of large-scale filaments extracted from an AREPO simulation of a Milky Way-like galaxy, we seek to understand the extent to which observed large-scale filament properties (with lengths $\gtrsim 100$ pc) can be explained by galactic dynamics alone. From an observer's perspective in the disk of the galaxy, we identify filaments forming purely due to galactic dynamics, without the effects of feedback or local self-gravity. We find that large-scale Galactic filaments are intrinsically rare, and we estimate that at maximum approximately one filament per $\rm kpc^{2}$ should be identified in projection, when viewed from the direction of our Sun in the Milky Way. In this idealized scenario, we find filaments in both the arm and interarm regions, and hypothesize that the former may be due to gas compression in the spiral-potential wells, with the latter due to differential rotation. Using the same analysis pipeline applied previously to observations, we analyze the physical properties of large-scale Galactic filaments, and quantify their sensitivity to projection effects and galactic environment (i.e. whether they lie in the arm or interarm regions). We find that observed "Giant Molecular Filaments" are consistent with being non-self-gravitating structures dominated by galactic dynamics. Straighter, narrower, and denser "Bone-like" filaments, like the paradigmatic Nessie filament, have similar column densities, velocity gradients, and Galactic plane heights ($z\approx$ 0 pc) to those in our simple model, but additional physical effects (such as feedback and self-gravity) must be invoked to explain their lengths and widths.

title: Deceleration and Electron Cooling of Highly Charged Ions at HITRAP
Creators: name: Rausch, Simon
Publisher: name: UNSPECIFIED
Year: 2025

description: The investigation of highly charged ions (HCI) offers the potential to recreate environments that are otherwise inaccessible on Earth. For instance, the magnetic field experienced by electrons in hydrogen-like heavy ions close to the surface of the nucleus compares to that in the vicinity of a pulsar. Consequently, this allows for the most stringent tests of fundamental theories, such as quantum electrodynamics (QED), in these extreme fields. Ultimate precision is typically attained in experiments conducted on cooled and confined ions in an ion trap. However, to date this remains a viable option only for light and medium-heavy, highly charged ions.
The production process of large quantities of heavy, highly charged ions, such as hydrogen-like uranium U⁹¹⁺, relies on electron stripping at high kinetic energies. This technique is commonly employed in accelerator facilities, such as the heavy ion research facility GSI Helmholtzzentrum für Schwerionenforschung in Germany. In order to confine heavy HCI in an ion trap for precision experiments, prior deceleration subsequent to the production process is necessary. This constitutes the objective of the HITRAP facility at GSI, where the energy of the ion beam is reduced in a linear decelerator. Subsequently, the ions will be captured in a Penning trap and cooled by the application of electron cooling for further transport to precision experiments.
In the context of the work, the linear decelerator was recommissioned following a shutdown period of almost eight years. For this purpose, ³⁶Ar¹⁸⁺ ions were produced by the accelerator complex of GSI, decelerated to 4 MeV/u in the Experimental Storage Ring ESR, and injected into the HITRAP facility. After successful deceleration, the ion beam was transported for the first time further along the low-energy beam line towards the HITRAP Cooling Trap, captured, and confined for short periods of time. Furthermore, the trap setup was commissioned with ⁴⁰Ar¹⁶⁺ ions produced by an electron beam ion trap (EBIT). The simultaneous storage of these ions with a cold plasma of electrons resulted in an considerable reduction of the ions' kinetic energy. This constitutes the first demonstration of electron cooling on highly charged ions in a Penning trap. Together with the first successful storage of accelerator-produced HCI, this marks a tremendous advancement in the commissioning of the HITRAP facility, as a result of which an experiment at HITRAP has been included for the first time in the beamtime schedule of GSI for the upcoming year.

description: We discuss a formulation of quantum field theory on quantum space time where the perturbation expansion of the S-matrix is term by term ultraviolet finite. The characteristic feature of our approach is a quantum version of the Wick product at coinciding points: the differences of coordinates q_j - q_k are not set equal to zero, which would violate the commutation relation between their components. We show that the optimal degree of approximate coincidence can be defined by the evaluation of a conditional expectation which replaces each function of q_j - q_k by its expectation value in optimally localized states, while leaving the mean coordinates (q_1 + ... + q_n)/n invariant. The resulting procedure is to a large extent unique, and is invariant under translations and rotations, but violates Lorentz invariance. Indeed, optimal localization refers to a specific Lorentz frame, where the electric and magnetic parts of the commutator of the coordinates have to coincide *). Employing an adiabatic switching, we show that the S-matrix is term by term finite. The matrix elements of the transfer matrix are determined, at each order in the perturbative expansion, by kernels with Gaussian decay in the Planck scale. The adiabatic limit and the large scale limit of this theory will be studied elsewhere. -- *) S. Doplicher, K. Fredenhagen, and J.E.Roberts, Commun. Math. Phys. 172, 187 (1995) [arXiv:hep-th/0303037]

description: Although the linear method is one of the most robust algorithms for optimizing non-linearly parametrized wavefunctions in variational Monte Carlo, it suffers from a memory bottleneck due to the fact at each optimization step a generalized eigenvalue problem is solved in which the Hamiltonian and overlap matrices are stored in memory. Here we demonstrate that by applying the Jacobi-Davidson algorithm, one can solve the generalized eigenvalue problem iteratively without having to build and store the matrices in question. The resulting direct linear method greatly lowers the cost and improves the scaling of the algorithm with respect to the number of parameters. To further improve the efficiency of optimization for wavefunctions with a large number of parameters, we use the first order method AMSGrad far from the minimum as it is very inexpensive, and only switch to the direct linear method near the end of the optimization where methods such as AMSGrad have long convergence tails. We apply this improved optimizer to various wavefunctions with both real and orbital space Jastrow factors for atomic systems such as Beryllium and Neon, molecular systems such as the Carbon dimer and Iron(II) Porphyrin, and model systems such as the Hubbard model and Hydrogen chains.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
