description: This paper examines intergenerational succession on Irish dairy farms. The factors that influence the decision to enter dairying farming are examined using a binary choice logit model. Reasons that are frequently published in the popular farming press as being an obstacle to intergenerational succession are analysed and the significance of their effect is quantified. Results show that the level of education of the heir is the most significant factor in the succession decision. Heir's with third level education are 30% less likely to enter dairy farming than their second level only educated counterparts. The sizes of milk quota and income that are associated with high probabilities of succession are identified.

On few aspects of the dynamics of granular matter

description: This paper, in French, describes a series of completely different behaviours of the mechanics of granular matter, which are obtained experimentally using periodic forcing at different amplitude, frequency and orientation. It starts with the problem of granular dissipative gas which has been investigated in micro-gravity ; it is found that such a gas exists only at very low density ; it is shown also that clustering occurs at larger density. Is this a phase transition ? The problem of dissipative Sinai billiard is then investigated briefly ; is it ergodic ? An experiment on propagation of acoustic wave is studied, with peculiar attention paid to scattering and diffusion that occurs when acoustic wavelength is comparable to the grain size. A third experiment demonstrates that bulk convection can be induced by slow (quasi static) horizontal forcing ; this flow is related to the quasi static rheology of granular matter, but looks rather like convection occurring under "dynamic vibration". A fourth experiment describes pure inertial effect, making the sand behaving as a perfect (non viscous) fluid ; in particular, it is shown that a static swell 9that does not propagate) is enforced at the interface between liquid and sand by strong periodic horizontal forcing .

description: In this paper we investigate the cosmological dynamics of geometric inflation by means of the tools of the dynamical systems theory. We focus in the study of two explicit models where it is possible to sum the infinite series of higher curvature corrections that arises in the formalism. These would be very interesting possibilities since, if regard gravity as a quantum effective theory, a key feature is that higher powers of the curvature invariants are involved at higher loops. Hence, naively, consideration of the whole infinite tower of curvature invariants amounts to consideration of all of the higher order loops. The global dynamics of these toy models in the phase space is discussed and the quantum origin of primordial inflation is exposed.

description: Non-Gaussianity of the cosmological matter density field can be largely reduced by a local Gaussianization transformation (and its approximations such as the logrithmic transformation). Such behavior can be recasted as the Gaussian copula hypothesis, and has been verified to very high accuracy at two-point level. On the other hand, statistically significant non-Gaussianities in the Gaussianized field have been detected in simulations. We point out that, this apparent inconsistency is caused by the very limited degrees of freedom in the copula function, which make it misleading as a diagnosis of residual non-Gaussianity in the Gaussianized field. Using the copula density, we highlight the departure from Gaussianity. We further quantify its impact in the predicted n-point correlation functions. We explore a remedy of the Gaussian copula hypothesis, which alleviates but not completely solves the above problems.

description: Moiré superlattices in transition metal dichalcogenide (TMD) heterostructures can host novel correlated quantum phenomena due to the interplay of narrow moiré flat bands and strong, long-range Coulomb interactions1-5. However, microscopic knowledge of the atomically-reconstructed moiré superlattice and resulting flat bands is still lacking, which is critical for fundamental understanding and control of the correlated moiré phenomena. Here we quantitatively study the moiré flat bands in three-dimensional (3D) reconstructed WSe2/WS2 moiré superlattices by comparing scanning tunneling spectroscopy (STS) of high quality exfoliated TMD heterostructure devices with ab initio simulations of TMD moiré superlattices. A strong 3D buckling reconstruction accompanied by large in-plane strain redistribution is identified in our WSe2/WS2 moiré heterostructures. STS imaging demonstrates that this results in a remarkably narrow and highly localized K-point moiré flat band at the valence band edge of the heterostructure. A series of moiré flat bands are observed at different energies that exhibit varying degrees of localization. Our observations contradict previous simplified theoretical models but agree quantitatively with ab initio simulations that fully capture the 3D structural reconstruction. Here the strain redistribution and 3D buckling dominate the effective moiré potential and result in moiré flat bands at the Brillouin zone K points.

description: The paper argues that current long-term projections of global meat and feed demand may underestimate future consumption patterns for mainly two reasons. First, they do not explicitly consider increased demand for protein foods of animal origin with rising incomes in some developing countries, and second they do not allow for changes in livestock technology, in particular feed demand. We then project the impact of both mechanisms to show the empirical relevance of our comments and suggest ready-to-use tools to consider them within standard projection models.

description: We study Lorentz-violating models of massive gravity which preserve rotations and are invariant under time-dependent shifts of the spatial coordinates. In the linear approximation the Newtonian potential in these models has an extra ``confining'' term proportional to the distance from the source. We argue that during cosmological expansion the Universe may be driven to an attractor point with larger symmetry which includes particular simultaneous dilatations of time and space coordinates. The confining term in the potential vanishes as one approaches the attractor. In the vicinity of the attractor the extra contribution is present in the Friedmann equation which, in a certain range of parameters, gives rise to the cosmic acceleration.

description: We report thermal expansion and magnetostriction in breathing pyrochlore magnets LiACr$_4$X$_8$ (A = Ga, In, X = O, S) measured by a dilatometric method on sintered samples. All four of these compounds showed a large volume contraction associated with antiferromagnetic order with decreasing temperature. Above the Neél temperature, LiGaCr4S8 showed negative thermal expansion, LiInCr4O8 showed positive thermal expansion with concave-downward temperature dependence, and LiInCr4S8 showed positive forced volume magnetostriction. All these phenomena are likely caused by the complex structure-magnetism correlation within the breathing pyrochlore structure with J and J'. These results suggested that breathing pyrochlore magnets are promising for the realization of various volumetric phenomena related to their magnetism not only in the magnetically-ordered phase but also in the paramagnetic phase.

description: Sustainable agriculture implies the exploitation of natural resources now, without compromising the natural resources stocks for the future generations. In the context of the paper, agricultural sustainability takes place at the interface between agriculture and the environment. The focus is on the interplay between farming systems and agri-environmental policies. Agricultural policies have major impacts on soil and water quality and on bio-diversity. Support commodity price policies have lead to serious problems of water pollution; high levels of soil erosion; nitrate losses and lost of biodiversity. The semi decoupeted income support policies and the introduction of the agri-environmental schemes under the 1992 CAP reform were the first attempts to correct the negative aspects of the production-orientated policies. For the first time farmers were regarded as countryside and landscape keepers and as environmental conservationists. Under the 2000 Agenda similar emphasis was given to the sustainability of agriculture. The objective of this paper is to evaluate the impact of the different agri-environmental policies on typical farming systems and consequently their effects on water pollution, soil erosion and bio-diversity/landscape. A bio-economic model, integrating a mathematical programming model and crop growth simulation model, is applied to estimated the changes in the levels of nitrogen leaching and soil erosion, and in the degree of bio-diversity under the current and proposed agricultural policy scenarios. The following farming systems are studied: dryland cereal farming systems (intensive and extensive), livestock and irrigated farming systems using conventional and conservation farming technologies. The results show The results show that the main changes on water pollution, soil erosion levels and biodiversity are mainly due to changes in price and arable compensatory payments. The agri-environmental measures are more important as farm income source than as a policy instrument to influence environmental parameters.

description: Due to an ever growing shortage of conventional energy sources, there is an increasingly intense interest in harnessing solar energy. The instant invention can contribute to the goal of achieving environmentally clean solar energy to be competitive with conventional energy sources. A novel method is described for manufacturing a transparent sheet with an embedded array of mirrored spheroidal micro-balls for use in a solar energy concentrator, and analogous applications such as optical switches and solar rocket assist. The micro-balls are covered with a thin spherical shell of lubricating liquid so that they are free to rotate in an almost frictionless encapsulation in the sheet. Novel method and apparatus are presented for producing the preferred embodiment of a close-packed monolayer of the array of mirrored micro-balls.

Spring-in of angled thermoset composite laminates
Creators: name: Albert, Carolyne I.
Publisher: name: University of British Columbia
Year: 2009

description: Advanced fibre-reinforced thermoset polymers are primarily used in the aerospace industry for their excellent mechanical properties and low weight. T o justify the use of these materials, low processing and manufacturing cost must counterbalance their high base cost. The necessity to produce parts within tight dimensional tolerances in the aerospace industry constitutes a challenge to cost-effective manufacturing as process-induced distortions are encountered in production. The current work focuses on spring-in, a change in angle occurring during processing of curved thermoset composite parts. Spring-in is encountered for virtually all curved thermoset composite parts and there is currently poor understanding o f the variables and mechanisms that affect this phenomenon. This thesis examines the effect of a number of design and process parameters on spring-in. The parameters studied include part geometry, lay-up, tool material, tool surface condition, cure cycle, and the use of a rubber caul sheet. The results show that process parameters have a significant impact on spring-in, in some cases more than doubling the value. Close examination of the parts made in this study reveals that spring-in can be decomposed into two components: a true corner component and a warpage component. The corner component is shown to be mainly the result of chemical and thermal strain anisotropy during processing. This component is repeatable with little variability for a given part design. Parameters affecting the corner component are the initial part angle and the part lay-up. The warpage component, on the other hand, is found to be driven by mechanical interaction between the tool and the part. This component is affected by the laminate thickness, the flange length, the cure cycle, the tool material, and the tool surface condition.
title: Catastrophic comparisons: International Relations through elsewhere
Creators: name: Van Wingerden, Enrike
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2023

description: Comparisons: International Relations Through Elsewhere is a study of comparisons in International Relations. Yet, it is not a comparative study in the conventional sense. This thesis is less concerned with using comparison as a particular technique of gathering, analyzing, and assessing information about the world than with understanding comparison as a way of intervening into that world. By excavating how and why people compare situations of political catastrophe, this thesis positions comparison as part of the equipment that actors in international relations draw upon in their worldly engagements. To investigate how comparisons do not simply capture but intervene in international relations, this thesis is based upon an ethnography of comparisons. Through ethnographic fieldwork and interviews, it analyzes how Palestine becomes compared to other sites of political contestation, focusing specifically on Ireland, South Africa, and Turtle Island (an Indigenous name for “North America”). These places have historical linkages with the Palestinian movement, and the Palestinian experiences of occupation, settler-colonialism, and repression continue to resonate deeply today. By studying the “catastrophic comparisons” that are drawn between these political contexts, this thesis argues that comparisons translate political experiences, (re)draw political relations, and (re)compose political issues in international relations. It traces the chains of matter and meaning that link everyday comparisons to the grander workings of international relations. Through comparison, Palestine becomes an amalgamation of heterogenous elements, a product of international multiplicity, composed of local trajectories as well as histories and futures elsewhere.

description: The optimal level of formalisation of contracts and their dynamic is at stake in the economic literature on the optimum design of ex post renegotiation with third party enforcement. Another theoretical interpretation is that contract adaptations may also reflect mutual learning process between contractors. Why transactors write explicit contract that they know cannot be court enforced? The central idea is that explicit contract terms makes it clearer to the transactors what has been agreed upon, thus are decreasing the cost of private enforcement sanctions (Klein, 1996). Empirical evidences are provided by the diachronic analysis of the full set of tri-partite contracts between one of the top-ten french large retailer and its beef suppliers before and after the BSE crisis (period 1993-1999). The analysis emphasizes also the role of this increased codification of supply contracts with a progressive change in the internal retailer's organization, i.e. increased centralization of decision and supervision mechanisms. Contract design and organizational choices are then strongly interrelated.

description: The Insect Resistant Maize for Africa (IRMA) project is currently developing Bt maize for Kenya. So far, Bt genes with resistance to Chilo partellus, Chilo orichalcociliellus, Eldana Sacharina, and Sesamia calamistis, four of the five major stemborers were successfully incorporated into elite CIMMYT maize inbred line (CML216) and tested in insect bioassays in Kenya. Participatory Rural Appraisals showed that stem borers are indeed a major pest problems for farmers. Four seasons of on-farm crop loss assessment showed an average crop loss of 13.5%, or 0.4 million tons, valued at US$ 80 million. If the project manages to find a Bt gene that is effective to the fifth stemborer, Busseola fusca, adoption rates are likely to be high, and therefore the returns. Under standard assumptions, the economic surplus of the project is calculated at $ 208 million over 25 years (66% of which is consumer surplus) as compared to a cost of $5.7 million. Geographically, the project should focus on the high production moist-transitional zone. However, if such gene cannot be found, Bt maize technology would only be effective in the low potential areas, and adoption rates would be fairly low, although benefits would still exceed costs.
External reconnection and resultant reconfiguration of overlying magnetic fields during sympathetic eruptions of two filaments

description: Sympathetic eruptions of two solar filaments have been studied for several decades, but the detailed physical process through which one erupting filament triggers another is still under debate. Here we investigate a sympathetic event involving successive eruptions of two filaments on 2015 November 15-16, which presented abundant sympathetic characteristics. The two filaments (F1 and F2) were separated by a narrow region of negative polarity, and F1 firstly erupted, producing a two-ribbon flare. When the outward-spreading ribbon produced by F1 approached stable F2, a weak brightening was observed to the south of F2 and then spread northward, inward approaching F2. Behind this inward-spreading brightening, a dimming region characterized by a plasma density reduction of 30% was extending. NLFFF extrapolations with a time sequence reveal that fields above pre-eruption F1 and F2 constituted a quadrupolar magnetic system with a possible null point. Moreover, the null point kept moving towards F2 and descending within the following hours.We infer that the rising F1 pushed its overlying fields towards the fields above stable F2 and caused successive external reconnection between the overlying fields. From outside to inside (lower and lower in height), the fields above pre-eruption F2 were gradually involved in the reconnection, manifesting as the inward-spreading brightening and extending dimming on the south side of F2. Furthermore, the external reconnection could reconfigure the overlying fields of F2 by transporting magnetic flux from its west part to the east part, which is further verified by the subsequent partial eruption of F2. We propose an integrated evidence chain to demonstrate the critical roles of external magnetic reconnection and the resultant reconfiguration of overlying fields on the sympathetic eruptions of two filaments.

description: Cotton is one of the most important smallholder cash crops in Sub-Saharan Africa (SSA). How to ensure input supply, credit recovery and competition is a subject of intense policy debate. This paper examines the performance of cotton sector development policies in Mozambique and Zambia. Both countries face the challenge of organizing input supply to farmers in the absence of rural credit markets, and competing in international markets distorted by production subsidies in developed countries. Both countries privatized cotton ginning in the 1990s. Emerging from civil war, Mozambique established geographical monopolies to interlink input and output markets and facilitate credit recovery. In Zambia, the government completely liberalized the cotton sector, forcing the private sector to deal with the problem of input distribution and credit recovery by itself. Despite being landlocked, Zambia's cotton sector has achieved better performance in terms of both value of cotton output per hectare and smallholder share of world market prices. An analysis of the institutional and technical factors behind the two countries' performance provides insights to guide the design of public/private partnerships relevant to many SSA countries.

description: In the Mid-Term Review (MTR), the European Commission proposed a series of changes to the Common Agricultural Policy (CAP). An important part of these changes was significant decoupling of support payments from production. In this paper, a partial equilibrium model of the EU agricultural sector is used to estimate the potential impacts of the MTR proposals on EU and world agricultural markets over the period 2004-2009. Effects of the MTR proposals are evaluated by comparing estimated outcomes under the proposals to those that would result under a current-policy baseline. The changes that are made in the MTR have the effect of reducing the production of the major commodities by varying amounts based on the importance of payments in production and the degree to which these payments are currently production inducing. For example, total area harvested for nine major crops falls by about 2 percent under the MTR proposals. In the livestock sector, however, where current payments are strongly coupled and form a large part of producers' income, the reductions in production are projected to be more significant.

Previous records were the factorization of RSA-768 in 2009 and a 768-bit discrete logarithm computation in 2016. Our two computations at the 795-bit level were done using the same hardware and software, and show that computing a discrete logarithm is not much harder than a factorization of the same size. Moreover, thanks to algorithmic variants and well-chosen parameters, our computations were significantly less expensive than anticipated based on previous records.The last page of this paper also reports on the factorization of RSA-250.

description: This paper seeks to address the question: why does poverty persist in rural Ethiopia? We argue that it is largely a lack of entitlements to fundamental livelihood assets which urges poor rural farmers into livelihood diversification to make a living. We base our findings on empirical work, which is based on information gathered from a three-round survey of 149 rural households in Ethiopia during 1999/2000 cropping season. The FGT poverty index is employed to examine the extent and severity of rural poverty and reveals that nearly 40% of the sample households live below poverty line with average poverty gap of 0.047. The binary logit estimates shed light on factors behind the persistence of poverty and indicates that rural poverty is strongly linked to entitlement failures to crucial assets such as land, human capital and oxen. The study also reveals that poor households attempt to smooth their consumption and income through livelihood diversification, among which petty trading, charcoal making and fuelwood gathering for sale, brewing and craftsmanship are the significant ones.

description: We present a path integral formulation of 't Hooft's derivation of quantum from classical physics. Our approach is based on two concepts: Faddeev-Jackiw's treatment of constrained systems and Gozzi's path integral formulation of classical mechanics. This treatment is compared with our earlier one [quant-ph/0409021] based on Dirac-Bergmann's method.

description: Multi-label classification is the challenging task of predicting the presence and absence of multiple targets, involving representation learning and label correlation modeling. We propose a novel framework for multi-label classification, Multivariate Probit Variational AutoEncoder (MPVAE), that effectively learns latent embedding spaces as well as label correlations. MPVAE learns and aligns two probabilistic embedding spaces for labels and features respectively. The decoder of MPVAE takes in the samples from the embedding spaces and models the joint distribution of output targets under a Multivariate Probit model by learning a shared covariance matrix. We show that MPVAE outperforms the existing state-of-the-art methods on a variety of application domains, using public real-world datasets. MPVAE is further shown to remain robust under noisy settings. Lastly, we demonstrate the interpretability of the learned covariance by a case study on a bird observation dataset.
Wave Excitation in Three-Dimensional Disks by External Potential

Subjects: subject: Astrophysics (astro-ph)

description: We study the excitation of density and bending waves and the associated angular momentum transfer in gaseous disks with finite thickness by a rotating external potential. The disk is assumed to be isothermal in the vertical direction and has no self-gravity. The disk perturbations are decomposed into different modes, each characterized by the azimuthal index m and the vertical index n, which specifies the nodal number of the density perturbation along the disk normal direction. The n=0 modes correspond to the two-dimensional density waves previously studied by Goldreich & Tremaine and others. In a three-dimensional disk, waves can be excited at both Lindblad resonances (for modes with n=0,1,2...) and vertical resonances (for the $n\ge 1$ modes only). The torque on the disk is positive for waves excited at outer Linblad/vertical resonances and negative at inner Lindblad/vertical resonances. While the n=0 modes are evanescent around corotation, the $n\ge 1$ modes can propagate into the corotation region where they are damped and deposit their angular momenta. We have derived analytical expressions for the amplitudes of different wave modes excited at Lindblad and/or vertical resonances and the resulting torques on the disk. It is found that for $n\ge 1$, angular momentum transfer through vertical resonances is much more efficient than Lindblad resonances. This implies that in some situations (e.g., a circumstellar disk perturbed by a planet in an inclined orbit), vertical resonances may be an important channel of angular momentum transfer between the disk and the external potential. We have also derived new formulae for the angular momentum deposition at corotation and studied wave excitations at disk boundaries.

description: We present electronic transport measurements through thiolated C$_{60}$ molecules in liquid environment. The molecules were placed within a mechanically controllable break junction using a single anchoring group per molecule. When varying the electrode separation of the C$_{60}$-modified junctions, we observed a peak in the conductance traces. The shape of the curves is strongly influenced by the environment of the junction as shown by measurements in two distinct solvents. In the framework of a simple resonant tunneling model, we can extract the electronic tunneling rates governing the transport properties of the junctions.

description: Proposals for agricultural trade reform put forward by the main protagonists remain far apart, with little sign of convergence. In an attempt to progress the negotiations towards a successful outcome, the chairman of the WTO Committee on Agriculture has proposed a compromise. The alternative proposals by the United States, the European Union and the WTO are analysed with the Agricultural Trade Policy Simulation Model, a static, multi-commodity, multi-region, partial equilibrium trade model. The estimated annual global welfare gains are $26 billion, $12 billion and $17 billion respectively. Least developed countries, as a group, gain from the US proposal but are made worse off under the WTO and EU proposals. Furthermore, in the best case many individual countries experience welfare losses. However, all countries enjoy increased export revenues and tariff revenues hold up quite well under the two less stringent proposals.
title: The cartography of dreams: application of computational linguistics to the study of sleep conscious experiences
Creators: name: Elce, Valentina

description: The study of dreams represents a crucial intersection between philosophical, psychological, neuroscientific, and clinical interests. Since dreams are subjective experiences spontaneously generated by the brain when it is partially disconnected from the external environment and thus is let free to operate in an unconstrained manner, their study could reveal specific mental processes that are different from those occurring during wakefulness and might provide crucial insights into brain functioning, both in physiological and pathological conditions. Given the high cost of sleep and dream research in terms of human effort and funding, open science and the building of large- scale datasets and repositories will constitute a key for significant advances in the field. At the same time, the analysis of large datasets will require a methodological shift, from human-based assessments to more automated approaches. For instance, methods based on natural language processing (NLP) could replace manual scales and rating approaches for the assessment of dream content. Such a methodological shift could also have positive consequences concerning the reproducibility and reliability of scientific results. Based on the above premises, we created Somnieve, a multimodal, open-source database collecting dream reports along with demographic information and psychometric, cognitive, and electroencephalographic measures obtained from a representative sample of the healthy Italian adult population. In particular, participants were asked to wear an actigraph and to record a report of their last dream experience each morning upon awakening for 14 days. Moreover, they completed a battery of questionnaires and cognitive tests. The database currently includes 1324 dream reports obtained from 161 healthy adult individuals (66M, 18-65y). Beside presenting and describing the Somnieve database, this Thesis work exploited the database to investigate the individual determinants of physiological dream content and recall frequency. We relied on computational linguistics to test whether it might be possible to implement computational linguistics based tools to automatically and objectively code dream content and verify the existence of generalizable semantic patterns in dream narratives. Moreover, we evaluated the inter- and intra-individual factors affecting dream recall frequency. Present results highlight the potential benefits that large multimodal databases like Somnieve could bring for the field of dream research. It is our hope that this, and similar independent efforts by other laboratories, will contribute to improve reproducibility in dream research and identify the individual determinants of dream content and recall frequency in physiological conditions, as well as quantify their possible pathological alterations.
