description: Planets form in protoplanetary discs. Their masses, distribution, and orbits sensitively depend on the structure of the protoplanetary discs. However, what sets the initial structure of the discs in terms of mass, radius and accretion rate is still unknown. We perform non-ideal MHD numerical simulations using the adaptive mesh refinement code Ramses, of a collapsing, one solar mass, molecular core to study the disc formation and early, up to 100 kyr, evolution, paying great attention to the impact of numerical resolution and accretion scheme. We found that while the mass of the central object is almost independent of the numerical parameters such as the resolution and the accretion scheme onto the sink particle, the disc mass, and to a lower extent its size, heavily depend on the accretion scheme, which we found, is itself resolution dependent. This implies that the accretion onto the star and through the disc are largely decoupled. For a relatively large domain of initial conditions (except at low magnetisation), we found that the properties of the disc do not change too significantly. In particular both the level of initial rotation and turbulence do not influence the disc properties provide the core is sufficiently magnetized. After a short relaxation phase, the disc settles in a stationary state. It then slowly grows in size but not in mass. The disc itself is weakly magnetized but its immediate surrounding is on the contrary highly magnetized. Our results show that the disc properties directly depend on the inner boundary condition, i.e. the accretion scheme onto the central object, suggesting that the disc mass is eventually controlled by the small scale accretion process, possibly the star-disc interaction. Because of ambipolar diffusion and its significant resistivity, the disc diversity remains limited and except for low magnetisation, their properties are (abridged).

description: The time dependence of nonclassical correlations is investigated for two fields (1,2) generated by an ensemble of cold Cesium atoms via the protocol of Duan et al. [Nature Vol. 414, p. 413 (2001)]. The correlation function R(t1,t2) for the ratio of cross to auto-correlations for the (1,2) fields at times (t1,t2) is found to have a maximum value Rmax=292(+-)57, which significantly violates the Cauchy-Schwarz inequality R<=1 for classical fields. Decoherence of quantum correlations is observed over 175 ns, and is described by our model, as is a new scheme to mitigate this effect.

description: This paper presents a work in progress on the development of a mental model of a food system using system analysis. The aim is to be able to use this model to create a mathematical simulation model that can be used to identify policy intervention opportunities, specifically focusing on the resilience, integrity and sustainability of food supply networks. The traditional view of food systems as supply chains with a downstream physical flow of products is extended to include the associated upstream flow of money and the decision chains that link these flows. Central to this work is the idea that supply systems are driven by profit and regulated by market dynamics and that these factors generate the underlying feedback structure of the system. Studying the structure of such systems as integrated supply-, valueand decision chains has underscored their complexity and the need for further, more food system specific research.

description: Time series observations of a single dithered field centered on the diffuse dwarf satellite galaxy Crater II were obtained with the Dark Energy Camera (DECam) at the 4m Blanco Telescope at Cerro Tololo Inter-American Observatory, Chile, uniformly covering up to two half-light radii. Analysis of the $g$ and $i$ time series results in the identification and characterization of 130 periodic variable stars, including 98 RR Lyrae stars, 7 anomalous Cepheids, and 1 SX Phoenicis star belonging to the Crater II population, and 24 foreground variables of different types. Using the large number of ab-type RR Lyrae stars present in the galaxy, we obtained a distance modulus to Crater II of $(m-M)_0=20.333\pm 0.004$ (stat) $\pm 0.07$ (sys). The distribution of the RR Lyrae stars suggests an elliptical shape for Crater II, with an ellipticity of 0.24 and a position angle of $153^\circ$. From the RR Lyrae stars we infer a small metallicity dispersion for the old population of Crater II of only 0.17 dex. There are hints that the most metal-poor stars in that narrow distribution have a wider distribution across the galaxy, while the slightly more metal rich part of the population is more centrally concentrated. Given the features in the color-magnitude diagram of Crater II, the anomalous Cepheids in this galaxy must have formed through a binary evolution channel of an old population.

description: Within the study, we show that it is quite demanding to conduct consumer surveys abroad, in particular, if the targeted society differs in so many ways from the one of the home market. The results of a study are presented analyzing consumer behavior in the Japanese rice market. We evaluated the preferences of Japanese consumers in rice. Amongst others, focus was set on origin (which is actually a prominent attribute in Western European food markets). To approximate the impact of relevant attributes influencing consumers’ purchasing decision (origin, brand, quality seals and price), a discrete choice experiment was conducted with Japanese consumers, mainly living in urban areas.

Superwind-driven Intense H$_2$ Emission in NGC 6240 II: Detailed Comparison of Kinematical and Morphological Structures of the Warm and Cold Molecular Gas

description: We report on our new analysis of the spatial and kinematical distribution of warm and cold molecular gas in NGC 6240, which was undertaken to explore the origin of its unusually luminous H$_2$ emission. By comparing three-dimensional emission-line data (in space and velocity) of CO (J=2-1) in the radio and H$_2$ in the near infrared, we are able to study the H$_2$ emitting efficiency, defined in terms of the intensity ratio of H$_2$ to CO [$I$(H$_2$)/$I$(CO)], as a function of velocity. The integrated H$_2$ emitting efficiency is calculated by integrating the velocity profile of H$_2$ emitting efficiency in blue, red, and total (blue + red) velocity regions of the profile. We find that (1) both the total H$_2$ emitting efficiency and the blue-to-red ratio of the efficiency are larger in regions surrounding the CO and H$_2$ intensity peaks, and (2) the H$_2$ emitting efficiency and the kinematical conditions in the warm molecular gas are closely related to each other. A collision between the molecular gas concentration and the external superwind outflow from the southern nucleus seems plausible to explain these characteristics, since it can reproduce the enhanced emitting efficiency of blueshifted H$_2$ around the molecular gas concentration, if we assume that the superwind blows from the southern nucleus toward us, hitting the entire gas concentration from behind. In this model, internal cloud-cloud collisions within the molecular gas concentration are enhanced by the interaction with the superwind outflow, and efficient and intense shock-excited H$_2$ emission is expected as a result of the cloud-crushing mechanism.

description: We consider a generic Hamiltonian that is suitable for describing a uniform BCS superfluid on a lattice with a two-point basis, and study its collective excitations at zero temperature. For this purpose, we first derive an effective-Gaussian action for the pairing fluctuations, and then extract the low-energy dispersion relations for the in-phase Goldstone and out-of-phase Leggett modes along with the corresponding amplitude (i.e., the so-called Higgs) ones. We find that while the Goldstone mode is gapless at zero momentum and propagating in general, the Leggett mode becomes undamped only with sufficiently strong interactions. Furthermore, we show that, in addition to the conventional contribution that is controlled by the energy of the Bloch bands, the velocity of the Goldstone mode has a geometric contribution that is governed by the quantum metric tensor of the Bloch states. Our results suggest that the latter contribution dominates the velocity when the former one becomes negligible for a narrow- or a flat-band.

HOLOTYPE: AMNH 673566, adult male, collected at Skull Creek, 20 miles south of Cape York (as on label), Queensland, Australia, in June 1912, by Robin Kemp (no. 1048). From the Mathews Collection (no. 13154) via the Rothschild Collection.
COMMENTS: In the original description, Mathews gave his catalog number of the holotype and noted that he ‘‘had now received a series of birds from [Cape York].’’ Mathews (1923b: 400) added that Robin Kemp collected the series for him. C. m. kempi was published on 18 September 1912, and only those specimens collected before that date can be included in the type series. It appears that Mathews had a series of two! All specimens in AMNH that Kemp collected on Cape York, other than the holotype and paratype, were collected after the publication of the name. The paratype is: AMNH 673564 (Mathews no. 13153), adult male, collected at Skull Creek in June 1912 by Kemp (no. 1047).

title: The teaching of science in English dissenting academies 1662-1800
Creators: name: Lewis, Olive
Publisher: name: The Open University
Year: 1989

description: This thesis attempts a new assessment of the place of science teaching in the English Dissenting Academies. It examines the approach to science teaching, seeking to account for the presence of science in the curricula of the Academies and its relationship to the wider educational aims. The content of science courses is examined together with the texts used and the relationships between the science taught and contemporary trends in scientific thought. Some attention is also given to the forms of teaching used in Dissenting Academies, and comparisons with the Universities. Solutions to these problems have been sought in a variety of sources: lecture notes, correspondence, published texts, formal minutes, prospectuses. Chapter 1 introduces the subject, and Chapters 2 to 8 cover the Academies. As there are over 90 known Academies it is not possible to examine each one in equal depth, thus four (Northampton, Moorfields/Stepney/Hoxton, Warrington and Hackney) have been chosen as case studies. These Academies were selected because sufficient material survives, and their dates collectively allow continuous and overlapping coverage from 1701 to 1796. The remaining Academies are discussed rather more briefly. Chapter 9 draws together the findings of Chapters 2 to 8, and attempts an assessment of the Academies by their approach to and teaching of scientific subjects. The most significant point about the science teaching in the Academies is the varied quality, which ranged from the exceptional to the merely perfunctory. In almost one half, there is no evidence to suggest that science was taught at all. Generalisations cannot be made on the strength of the excellence of individual Academies or tutors, for example Priestley, Forster or Dalton, all of whom taught in these institutions. The reasons for including the subject on the curriculum also vary including specialist courses for students intending to follow medical or commercial careers, but in most Academies, the central reason is related to Christian belief, and the use of scientific knowledge to support the theological argument from design. An antithesis between the Academies' aim to train ministers and at the same time, to offer a broad general education, can be perceived in attitudes towards science, and it is possible to suggest a more convincing reason for the decline of the Academies than those hitherto advanced.

description: Numerical modeling of polycrystal plasticity is computationally intensive. We employ Graph Neural Networks (GNN) to predict stresses on complex geometries for polycrystal plasticity from Finite Element Method (FEM) simulations. We present a novel message-passing GNN that encodes nodal strain and edge distances between FEM mesh cells, and aggregates to obtain embeddings and combines the decoded embeddings with the nodal strains to predict stress tensors on graph nodes. The GNN is trained on subgraphs generated from FEM mesh graphs, in which the mesh cells are converted to nodes and edges are created between adjacent cells. We apply the trained GNN to periodic polycrystals with complex geometries and learn the strain-stress maps based on crystal plasticity theory. The GNN is accurately trained on FEM graphs, in which the $R^2$ for both training and testing sets are larger than 0.99. The proposed GNN approach speeds up more than 150 times compared with FEM on stress predictions. We also apply the trained GNN to unseen simulations for validations and the GNN generalizes well with an overall $R^2$ of 0.992. The GNN accurately predicts the von Mises stress on polycrystals. The proposed model does not overfit and generalizes well beyond the training data, as the error distributions demonstrate. This work outlooks surrogating crystal plasticity simulations using graph data.

title: ObLog: the combination of object-oriented and logic programming
Creators: name: Watkins, John
Publisher: name: The Open University
Year: 1990

description: Object-oriented programming has often been advocated as a means of improving and enhancing the facilities provided by a given programming environment. This thesis is concerned with an examination of the benefits of providing object-oriented facilities in the Logic programming language - Prolog. We consider these benefits from two different perspectives, specifically examining what benefits Prolog can gain from objects, and conversely, what benefits object-oriented programming can gain from Prolog. A previously proposed model of object execution in Prolog was used as the basis of this research. In implementing this proposal we have critically examined how well the model supports the principles of object-oriented programming, and in those areas which we consider deficient, identified alternatives for improving the model which have subsequently been implemented for the purposes of assessment. The name we have selected for our augmented system is ObLog, drawn from Ob(jects) in (Pro)log. We critically examine the suitability of ObLog in terms of object-oriented programming by implementing a series of example applications based on a Block World specification. The thesis concludes by proposing some areas in which further research might usefully be conducted.

description: We investigate gravitational perturbations in a compact six-dimensional self-tuning brane model. We specifically look for analytic solutions to the perturbed Einstein equations that correspond in four-dimensions to massless or approximately massless scalars coupled to matter on the brane. The presence of such modes with gravitational couplings would be phenomenologically unacceptable. The most general solution for all such modes is obtained, but it is found that they are all eliminated by the boundary conditions. Our main result is that to linear order in perturbation theory this model does not contain any light scalars. We speculate that this model does not self-tune.

description: Climate change is a serious threat to Indian agriculture affecting crop production and livelihood. The study documents the perception of 500 farmers on climate change as well as awareness and extent of adaptation strategies followed at wheat farms captured by survey (2016-17) apart from tracking yield sensitivity by employing two-stage step-wise regression. Findings indicated that perception matched with the climatology. Investigation alerted that a majority (56.6%) have not changed wheat varieties despite climate change belief barring Haryana wherein, 54% seed replacement exists. Yield has increased over time with no significant change in straw yield, grain and straw quality. Mapping of sensitive stages in crop growth indicated that minimum temperature, relative humidity and rainfall were affecting yield at early stage, whereas, maximum temperature influence yield at maturity stage. The survey explicitly alarms that barring a few strategies like application of organic manures, new varieties, crop insurance and irrigation management, the awareness on rest of the adaptation practices is very low among the wheat producers. Further, every technology is embedded with socio-economic constraints in adoption. The study advocates for implementation of region-specific participatory climate-smart farming practices and/or adaptation strategies through targeted extension programs to manage the yield sensitivity against climate change.

description: We discuss finite-difference time-domain simulations of femtosecond pulses interacting with silver nanowires and nanoparticles. We show how localized hot spots near the metal surfaces can be generated and controlled in a spatiotemporal manner. The control is made possible by chirping the pulses such that the effective frequency passes through surface plasmon resonances associated with different spatial regions of the nanostructure over the course of time. The response of such nanostructures to chirped pulses could provide a novel means of encoding or decoding optical signals.

description: We theoretically propose a simple setup based on a three terminal triple quantum dot in the Coulomb blockade regime as a heat flow allocator to spatially separate heat flows along two different channels at arbitrary proportion. We show that a constant output heat flow ratio can be obtained in a wide range of system parameters and any ratio of the output heat flow, whether it is an integer ratio or a fractional ratio, can be obtained by directly adjusting the ratio of the energy-dependent tunneling rate.

description: We present necessary and sufficient conditions to have global hypoellipticity and global solvability for a class of vector fields defined on a product of compact Lie groups. In view of Greenfield's and Wallach's conjecture, about the non-existence of globally hypoelliptic vector fields on compact manifolds different from tori, we also investigate different notions of regularity weaker than global hypoellipticity and describe completely the global hypoellipticity and global solvability of zero-order perturbations of our vector fields. We also present a class of vector fields with variable coefficients whose operators can be reduced to a normal form, and we prove that the study of the global properties of such operators is equivalent to the study of the respective properties for their normal forms.

description: On large scales, the Lyman-$α$ forest provides insights into the expansion history of the Universe, while on small scales, it imposes strict constraints on the growth history, the nature of dark matter, and the sum of neutrino masses. This work introduces ForestFlow, a novel framework that bridges the gap between large- and small-scale analyses, which have traditionally relied on distinct modeling approaches. Using conditional normalizing flows, ForestFlow predicts the two Lyman-$α$ linear biases ($b_δ$ and $b_η$) and six parameters describing small-scale deviations of the three-dimensional flux power spectrum ($P_\mathrm{3D}$) from linear theory as a function of cosmology and intergalactic medium physics. These are then combined with a Boltzmann solver to make consistent predictions, from arbitrarily large scales down to the nonlinear regime, for $P_\mathrm{3D}$ and any other statistics derived from it. Trained on a suite of 30 fixed-and-paired cosmological hydrodynamical simulations spanning redshifts from $z=2$ to 4.5, ForestFlow achieves 3 and 1.5\% precision in describing $P_\mathrm{3D}$ and the one-dimensional flux power spectrum ($P_\mathrm{1D}$) from linear scales to $k=5\,\mathrm{Mpc}^{-1}$ and $k_\parallel=4\,\mathrm{Mpc}^{-1}$, respectively. Thanks to its conditional parameterization, ForestFlow shows similar performance for ionization histories and two $Λ$CDM model extensions $\unicode{x2013}$ massive neutrinos and curvature $\unicode{x2013}$ even though none of these are included in the training set. This framework will enable full-scale cosmological analyses of Lyman-$α$ forest measurements from the DESI survey.

description: A generally accepted approach to support and increase small-scale farmers living standards in developing countries is to improve their management capacities by means of agricultural training. In this respect, capacity development is the most efficient and used method to train farmers. However, there is a lack of quantitative information about farmers preferences of those activities, which are crucial to refine capacity development activities in the future. This study employs a discrete choice experiment analysing the willingness to pay to determine the preferences of small-scale farmers for agricultural training with respect to the training method, trainer, duration, location and additional offers. The main finding is that most important for farmers are training methods including demonstration. Furthermore, farmers would like to receive additional offers during the training and would like to be trained by an trainer with an academic background. Farmers are also willing to pay for these types of training. The outcomes could provide relevant politicians and other stakeholders the opportunity to improve their training programmes and, in the end, make capacity development more efficient.

Filling the Magnetospheres of Weak Pulsars

description: Recent advances in numerical algorithms and computational power have enabled first-principles simulations of pulsar magnetospheres using Particle-in-Cell (PIC) techniques. These ab-initio simulations seem to indicate that pair creation through photon-photon collision at the light cylinder is required to sustain the pulsar engine. However, for many rotation-powered pulsars pair creation operates effectively only near the stellar surface where magnetic field is high. How these "weak pulsars" fill their magnetospheres without efficient photon-photon pair conversion in the outer magnetosphere is still an open question. In this paper, we present a range of self-consistent solutions to the pulsar magnetosphere that do not require pair production near the light cylinder. When pair production is very efficient near the star, the pulsar magnetosphere converges to previously-reported solutions. However, in the intermediate regime where pair supply is barely enough to sustain the magnetospheric current, we observe a time-dependent solution with quasi-period about half of the rotation period. This new quasi-periodic solution may explain the observed pulsar death line without invoking multipolar components near the star, and can potentially explain the core vs. conal emission patterns observed in pulsar radio signals.

description: We demonstrate an exact equivalence between classical population dynamics and Lindbladian evolution admitting a dark state and obeying a set of certain local symmetries. We then introduce {\em quantum population dynamics} as models in which this local symmetry condition is relaxed. This allows for non-classical processes in which animals behave like Schrödinger's cat and enter superpositions of live and dead states, thus resulting in coherent superpositions of different population numbers. We develop a field theory treatment of quantum population models as a synthesis of Keldysh and third quantization techniques and draw comparisons to the stochastic Doi-Peliti field theory description of classical population models. We apply this formalism to study a prototypical ``Schrödigner cat'' population model on a $d$-dimensional lattice, which exhibits a phase transition between a dark extinct phase and an active phase that supports a stable quantum population. Using a perturbative renormalization group approach, we find a critical scaling of the Schrödinger cat population distinct from that observed in both classical population dynamics and usual quantum phase transitions.

description: We investigate the non-Hermitian Su-Schrieffer-Heeger (SSH) model on Bethe lattice, revealing a novel localization phenomenon coined inner non-Hermitian skin effect. This effect is featured by the localization of all eigenstates within the bulk of the lattice, diverging from the conventional skin effect observed in general non-Hermitian systems. The analytical treatment of the model demonstrates that the Hamiltonian can be decoupled into a series of one-dimensional chains, with one end fixed at the bottom boundary while the other ends positioned at varying generations within the bulk. This configuration leads to the emergence of the inner non-Hermitian skin effect, which is further validated by performing circuit simulations. Our findings provide new insights into the interplay between non-Hermitian physics and the self-similar structure on Bethe lattice.

description: We present a detailed finite-temperature Hartree-Fock-Bogoliubov (HFB) treatment of the two-dimensional trapped Bose gas. We highlight the numerical methods required to obtain solutions to the HFB equations within the Popov approximation, the derivation of which we outline. This method has previously been applied successfully to the three-dimensional case and we focus on the unique features of the system which are due to its reduced dimensionality. These can be found in the spectrum of low-lying excitations and in the coherence properties. We calculate the Bragg response and the coherence length within the condensate in analogy with experiments performed in the quasi-one-dimensional regime [Richard et al., Phys. Rev. Lett. 91, 010405 (2003)] and compare to results calculated for the one-dimensional case. We then make predictions for the experimental observation of the quasicondensate phase via Bragg spectroscopy in the quasi-two-dimensional regime.

description: Competency question (CQ) formulation is central to several ontology development and evaluation methodologies. Traditionally, the task of crafting these competency questions heavily relies on the effort of domain experts and knowledge engineers which is often time-consuming and labor-intensive. With the emergence of Large Language Models (LLMs), there arises the possibility to automate and enhance this process. Unlike other similar works which use existing ontologies or knowledge graphs as input to LLMs, we present a retrieval-augmented generation (RAG) approach that uses LLMs for the automatic generation of CQs given a set of scientific papers considered to be a domain knowledge base. We investigate its performance and specifically, we study the impact of different number of papers to the RAG and different temperature setting of the LLM. We conduct experiments using GPT-4 on two domain ontology engineering tasks and compare results against ground-truth CQs constructed by domain experts. Empirical assessments on the results, utilizing evaluation metrics (precision and consistency), reveal that compared to zero-shot prompting, adding relevant domain knowledge to the RAG improves the performance of LLMs on generating CQs for concrete ontology engineering tasks.
