description: The problem of a fermion subject to a general scalar potential in a two-dimensional world is mapped into a Sturm-Liouville problem for nonzero eigenenergies. The searching for possible bounded solutions is done in the circumstance of power-law potentials. The normalizable zero-eigenmode solutions are also searched. For the specific case of an inversely linear potential, which gives rise to an effective Kratzer potential, exact bounded solutions are found in closed form. The behaviour of the upper and lower components of the Dirac spinor is discussed in detail and some unusual results are revealed.

description: Comparisons of trends in food production and consumption in 106 developing countries during 1967-80 showed that deterioration in food calorie balances because of shrinking calorie surplus or widening calorie gaps was more than twice as common as were incidences of expanding calorie surpluses or narrowing calorie gaps. Continued growth in net food exports to these countries is highly probable during the rest of the eighties. Fifty net calorie importers with widening calorie gaps comprise the core of the world's current and prospective problems in food security and human malnutrition. Causes of intercountry differences in food self-sufficiency are identified.

description: Eating out no longer is reserved for special occasions. Expenditures for eating out now account for 41 cents of every food dollar, up from 27 cents in 1960. Growth has been phenomenal. With growth, changes were inevitable --changes in the structure and organization of the industry, in food purchasing and ordering practices, in the mix of foods served, and in food marketing and distribution systems. _Such changes affect food producers, manufacturers, middlemen, and consumers. This report provides a framework for measuring changes occurring in the foodservice industry. It defines the industry and its many segments and describes a methodology for estimating the retail and purchase values of meals and snacks and the quantity of food moving through the industry on a market segment-by-segment basis.

description: The chiral phase boundary of strong matter is determined in the T-μplane from the chiral quark model, applying a non-perturbatively renormalised treatment, involving chains of pion-bubbles and 1-loop fermion contributions. In the absence of explicit symmetry breaking the second order portion of the phase boundary and the location of the tricritical point (TCP) are determined analytically. Sensitivity of the results to the renormalisation scale is carefully investigated. The softening of the sigma-pole near the second order transitions is confirmed.

description: The mechanical response of active media ranging from biological gels to living tissues is governed by a subtle interplay between viscosity and elasticity. In this Letter, we generalize the canonical Kelvin-Voigt and Maxwell models to active viscoelastic media that break both parity and time-reversal symmetries. The resulting continuum theories exhibit viscous and elastic tensors that are both antisymmetric, or odd, under exchange of pairs of indices. We analyze how these parity violating viscoelastic coefficients determine the relaxation mechanisms and wave-propagation properties of odd materials.

description: Partial information decomposition (PID) of the multivariate mutual information describes the distinct ways in which a set of source variables contains information about a target variable. The groundbreaking work of Williams and Beer has shown that this decomposition cannot be determined from classic information theory without making additional assumptions, and several candidate measures have been proposed, often drawing on principles from related fields such as decision theory. None of these measures is differentiable with respect to the underlying probability mass function. We here present a novel measure that satisfies this property, emerges solely from information-theoretic principles, and has the form of a local mutual information. We show how the measure can be understood from the perspective of exclusions of probability mass, a principle that is foundational to the original definition of the mutual information by Fano. Since our measure is well-defined for individual realizations of the random variables it lends itself for example to local learning in artificial neural networks. We also show that it has a meaningful Möbius inversion on a redundancy lattice and obeys a target chain rule. We give an operational interpretation of the measure based on the decisions that an agent should take if given only the shared information.

description: We present and analyse new optical images of the dust envelope surrounding the high mass-loss carbon star IRC+10216. This envelope is seen due to external illumination by galactic light. Intensity profiles and colors of the nebula were obtained in the UBV bandpasses. The data are compared with the results of a radiative transfer model calculating multiple scattering of interstellar field photons by dust grains with a single radius. The data show that the observed radial shape of the nebula, especially its half maximum radius, does not depend on wavelength (within experimental errors), suggesting that grains scatter in the grey regime, etc, etc (this abstract has been shortened)

description: Restrictive trade policies of both grain importing and exporting .countries and increasing variability in the world monetary system are causing increased fluctuations in U.S. grain exports and.increased price uncertainty for U.S. producers. This uncertainty reduces production efficiency and economic welfare, and affects the financial organization and structure of U.S. agriculture. While these problems will likely continue and may worsen over the next 20 years, policies to share or ameliorate such effects are costly and have other undesirable side-effects. U.S. grain policy alternatives must recognize linkages between increasingly variable world grain markets and U.S. agriculture.
α2, oxygen and the micromechanics of α-titanium
Creators: name: Dear, Felicity Frederika
Publisher: name: Imperial College London
Year: 2021

description: The micromechanical behaviour of titanium alloys underpins their use in critical rotating parts of aero engines. Time-dependent and spatially heterogeneous slip are key contributors to dwell fatigue crack initiation, and the aim of this work has been to contribute mechanistic understanding of factors controlling slip character and dwell sensitivity. This thesis addresses the phase metallurgy and mesoscale plasticity of Ti–Al–X and Ti–Sn alloys, which model the hcp α phase of many structural alloys. The influence of O, V and Mo on α2 Ti3Al formation in Ti–7Al (wt.%) alloys was characterised using transmission electron microscopy (TEM), atom probe tomography (APT) and small-angle X-ray scattering (SAXS). Isothermal ageing was conducted at 550 ° C for times up to 120 d. Precipitates reached sizes of 10–20 nm and 6–10% volume fraction. O was found to increase volume fraction, while V and Mo had little effect. All solutes, particularly Mo, promoted higher nucleation density and smaller precipitates. The effect of solutionising temperature on nucleation density was also investigated. Results supported the proposal that α2 nucleation is mediated by vacancy concentration prior to ageing and subsequent coarsening. Ti–7Al–0.05O and Ti–7Al–0.25O alloys in both quenched and aged conditions were investigated using tensile, creep and stress relaxation testing to explore the effects of O and α2 on micromechanics. TEM analysis of dislocation configurations after stress relaxation showed that both O and α2 restricted dislocation motion to slip bands, but that O encouraged appreciable cross-slip while α2 prevented it. In situ far-field high energy X-ray diffractometry (ff-HEDM) during creep testing revealed that interstitial oxygen promotes more frequent, smaller slip events, while α2 encouraged larger slip avalanches. These results indicate that interstitial oxygen helps smooth the stochastic nature of slip at the grain scale, while α2 worsens it. The relative merits of Al and Sn as α-stabilisers and solid solution strengtheners were assessed. For three compositions in each system around the α/α+α2 boundary, solutionised and aged microstructures were compared using TEM, SAXS and tensile testing. It was determined that, at the solubility limit for each solute, Al provides greater specific strengthening while avoiding the risk of deleterious crystallographic ordering. These results also allowed assessment of the position of phase boundaries. Drawing on the mechanistic insights for α2 formation and slip heterogeneity in α-Ti, implications for dwell fatigue crack initiation and proposals for alloy development strategies are outlined.

Characterising the distributions of height and body-mass index and their interrelationship
Creators: name: Iurilli, Maria Laura Caminia
Publisher: name: Imperial College London
Year: 2021

description: Height and weight are indicators of healthy versus unhealthy nutrition. Body-mass index (BMI) measures weight gain beyond what is expected from height gain. Having short stature or too little weight for one’s height, represented by low BMI, as well as having excessive weight for one’s height, represented by high BMI, increases the risk of morbidity and mortality. My thesis aimed to provide summary statistics that characterise the distributions of height and BMI and their interrelationship. Data were collated via the NCD Risk Factor Collaboration (NCD-RisC) network, from population-based studies that had anthropometrics measurements from 1985 to 2019 for a total of 2,896 studies with 187 million participants. Of these, 1,282 surveys provided over 11 million participants aged 20 to 79 years, with 1,021 surveys of over 1.4 million women aged 40-49 years and 815 surveys of over 870,000 men aged 40-49 years. I used a hierarchical Bayesian model to estimate mean, variance and skewness of height and BMI, as well as their correlation coefficient; I also used a regression model to estimate the contribution of the change in mean BMI to the change of prevalence in underweight and obesity. In 2019 versus 1985, mean and variance of both the height and BMI distributions increased in most countries and sexes; skewness of the height distribution remained around zero for both women and men in most countries, while skewness of the BMI distribution, although it was a positive number for both sexes, it decreased in women from most countries and increased in men from all countries. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, were largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. The correlation coefficient between height and BMI did not change significantly from zero for most countries and sexes. Considering that the height gain was not proportional to the BMI increase, segments of the two distributions were affected heterogeneously so policy makers and health practitioners need to tackle the double burden of malnutrition.

description: This paper critically surveys 10 studies that test the meta-production function hypothesis, which states that intercountry agricultural production variation is partly explained by different levels of human capital. The meta-production function exhibits constant returns to scale without human capital variables; with human capital, they estimate increasing returns. Some variables (land and general education) lack statistical significance. In subsample estimates, developed countries exhibit increasing returns to scale while less developed countries exhibit constant returns to scale. The production function is stable over time. Inadequate measurements are a serious problem; suggestions for improved measurements are offered for future studies.

description: We present the first experimental measurements of the isotropic and nematic phases of mixtures of thin, charged semiflexible fd virus, and thick, fd-PEG created by covalently grafting poly-(ethylene glycol) to the the surface of fd, rods. The fd-PEG is sterically stabilized and its phase behavior is independent of ionic strength. The fd is charged. Therefore, by varying the ionic strength of a mixture of fd and fd-PEG, only the effective diameter of the bare fd rods changes, subsequently varying the effective diameter ratio (d=D_fd-PEG/D_fd) from 3.7 to 1. In solution, binary mixtures of fd and fd-PEG are shown to exhibit isotropic-nematic, isotropic-nematic-nematic and nematic-nematic coexisting phases with increasing concentration. We measure the binary phase diagrams as a function of composition, total concentration, and ionic strength. We find a lower critical point in the nematic-nematic coexistence region which has not been observed previously. These experimental results resolve a controversy in the literature concerning the evolution of the nematic-nematic phase separation with concentration. The experimental results are qualitatively described by a rescaled Onsager-type theory for the phase behavior of binary rod mixtures.

Cosmic String Cusps with Small-Scale Structure: Their Forms and Gravitational Waveforms

description: We present a method for the introduction of small-scale structure into strings constructed from products of rotation matrices. We use this method to illustrate a range of possibilities for the shape of cusps that depends on the properties of the small-scale structure. We further argue that the presence of structure at cusps under most circumstances leads to the formation of loops at the size of the smallest scales. On the other hand we show that the gravitational waveform of a cusp remains generally unchanged; the primary effect of small-scale structure is to smooth out the sharp waveform emitted in the direction of cusp motion.

description: The European Community (EC) has launched its quest for a border-free Europe as envisioned in 1957 in the Treaty of Rome. On January 1, 1993, all impediments to the free movement of goods, services, capital, and people inside the EC are to be eliminated. The elimination of internal trade barriers in the EC will have direct and indirect effects on the demand, supply, and trade of the EC's food and agricultural sector. This volume addresses these implications in seven separate chapters, organized by theme. The first three chapters emphasize the effects of fiscal, physical, and technical changes that EC 1992 requires, with special emphasis on the food industry. The fourth and fifth chapters focus on the potential effects on the Common Agricultural Policy (CAP), with a special paper dedicated to the effects of German unification on the CAP. The last two chapters concern the regional implications for world food and agricultural trade.

The main goal of these simulations is to study the dependence of MCAO performance upon the altitude of the high-altitude conjugated DM and thereby determine its optimal conjugation. The performance is also studied with respect to the geometry of the Guide Star constellation when using constellations of Natural Guide Stars (NGS), which are rare, or constellations of Laser Guide Stars (LGS) which would allow large sky coverage.

description: The alternating direction method of multipliers (ADMM) is a widely used method for solving many convex minimization models arising in signal and image processing. In this paper, we propose an inertial ADMM for solving a two-block separable convex minimization problem with linear equality constraints. This algorithm is obtained by making use of the inertial Douglas-Rachford splitting algorithm to the corresponding dual of the primal problem. We study the convergence analysis of the proposed algorithm in infinite-dimensional Hilbert spaces. Furthermore, we apply the proposed algorithm on the robust principal component pursuit problem and also compare it with other state-of-the-art algorithms. Numerical results demonstrate the advantage of the proposed algorithm.

 Type material. Holotype (ZIN 1 /532-2021) and 32 paratypes (ZIN 2 /532-2021) derive from the same lot, labeled “50/1957” (Tab. 1, locality 16), collected by B.M. Logvinenko off Cheleken Peninsula on 4 August 1957.
Further 128 paratypes (ZIN 3 /532-2021–8/532-2021, 11/532-2021 and 12/532-2021) are stored in eight separate tubes, labels only marked with the number of station and year, collected in various parts of the Middle (Tab. 1, locality 2) and South (localities 14, 15, 16, 17, 21, 42) Caspian Sea between 26 June 1956 and 2 August 1957 (Fig. 1).
 Type locality. Originally given as “Southern Caspian Sea between 40–75 m water depth” without further details (Logvinenko & Starobogatov 1969). The holotype was collected in the Caspian Sea off the Cheleken Peninsula, Turkmenistan (Table 1, locality 16) from 71 m depth.
 Remarks. Recently rediscovered material determined by Starobogatov as the paratypes of C. isseli contain a variety of morphologies. Some match the typical C. isseli as described by Logvinenko & Starobogatov (1969) and the morphology of the holotype (Fig. 2a, b). However, some paratypes (Fig. 2i, j, o–r) resemble C. pallasii (Clessin & W. Dybowski in W. Dybowski, 1887) closely and study of these and additional material confirms that some of the paratypes were classified under that species correctly (Anistratenko et al. 2021).
 Despite their overall similarity in shell shape, C. pallasii can be distinguished from C. isseli by the consistently lower whorl base, the less convex whorl profile, the slightly detached aperture and the larger and more bulbous protoconch. Clathrocaspia isseli differs from C. gmelinii (Clessin & W. Dybowski in W. Dybowski, 1887) in its more slender shape (see Anistratenko et al. 2021 for further details).
 Distribution. Endemic to the Caspian Sea, only known from 8 localities (see above) in the Middle and South Basins from water depths of 40 and 107 m. Also found in the Holocene deposits of the Kura delta (Anistratenko et al. 2021).

description: We use geometric considerations to study transport properties, such as the conductivity and Hall coefficient, near the onset of a nesting-driven spin density wave in a simple metal. In particular, motivated by recent experiments on vanadium-doped chromium, we study the variation of transport coefficients with the onset of magnetism within a mean-field treatment of a model that contains nearly nested electron and hole Fermi surfaces. We show that most transport coefficients display a leading dependence that is linear in the energy gap. The coefficient of the linear term, though, can be small. In particular, we find that the Hall conductivity $σ_{xy}$ is essentially unchanged, due to electron-hole compensation, as the system goes through the quantum critical point. This conclusion extends a similar observation we made earlier for the case of completely flat Fermi surfaces to the immediate vicinity of the quantum critical point where nesting is present but not perfect.

Application of x-ray diagnostics to the characterisation of pulsed power driven magnetic reconnection experiments
Creators: name: Halliday, Jonathan
Publisher: name: Imperial College London
Year: 2020

description: This thesis describes results obtained using a versatile, pulsed power driven platform for magnetic reconnection experiments. The platform used the MAGPIE generator (1.4 MA, 240 ns) to produce plasma inflows (Vin ≈ 50 km s−1) that carry a strong azimuthal magnetic field (Bin 3 T) and persisted for many hydrodynamic timescales. The platform consisted of a pair of inverse (or exploding) wire arrays, and the plasma flows were generated by the ablation of material from these arrays. Plasma conditions were diagnosed with an existing suite of high spatial and temporal resolution laser probing diagnostics including laser interferometry, Thomson scattering, and Faraday rotation imaging. These results indicated that the plasma flows from the two arrays carried oppositely directed magnetic fields and that, in the region where the two flows met, magnetic flux was efficiently annihilated in a well defined reconnection layer. The magnetic energy released in the flux annihilation process was observed to cause plasma heating, and to increase fluid velocity in the outflows. The reconnection layer was observed to be unstable to the plasmoid instability. Preliminary evidence indicated that the reconnecting plasma generated a population of fast electrons. In order to investigate this possibility in more detail, a variety of X-Ray diagnostics were used to characterise experimental conditions. These included spherically bent crystal X-Ray spectroscopy; time integrated, filtered pinhole imaging; and time resolved, filtered slit imaging. The results obtained using X-Ray diagnostics were consistent with the previous laser probing measurements, but do not conclusively prove that particle acceleration occurred in the experiments

description: Each spacecraft in the Laser Interferometer Space Antenna houses a proof mass which follows a geodesic through spacetime. Disturbances which change the proof mass position, momentum, and/or acceleration will appear in the LISA data stream as additive quadratic functions. These data disturbances inhibit signal extraction and must be removed. In this paper we discuss the identification and fitting of monochromatic signals in the data set in the presence of data disturbances. We also present a preliminary analysis of the extent of science result limitations with respect to the frequency of data disturbances.

description: Human knowledge provides a formal understanding of the world. Knowledge graphs that represent structural relations between entities have become an increasingly popular research direction towards cognition and human-level intelligence. In this survey, we provide a comprehensive review of knowledge graph covering overall research topics about 1) knowledge graph representation learning, 2) knowledge acquisition and completion, 3) temporal knowledge graph, and 4) knowledge-aware applications, and summarize recent breakthroughs and perspective directions to facilitate future research. We propose a full-view categorization and new taxonomies on these topics. Knowledge graph embedding is organized from four aspects of representation space, scoring function, encoding models, and auxiliary information. For knowledge acquisition, especially knowledge graph completion, embedding methods, path inference, and logical rule reasoning, are reviewed. We further explore several emerging topics, including meta relational learning, commonsense reasoning, and temporal knowledge graphs. To facilitate future research on knowledge graphs, we also provide a curated collection of datasets and open-source libraries on different tasks. In the end, we have a thorough outlook on several promising research directions.
On the Hawking-Page Transition and the Cardy-Verlinde formula

description: The free energies of the conformal field theories dual to charged adS and rotating adS black holes show Hawking-Page phase transition. We study the transition by constructing boundary free energies in terms of order parameters. This is done by employing Landau's phenomenological theory of first order phase transition. The Cardy-Verlinde formula is then showed to follow quite naturally. We further make some general observations on the Cardy-Verlinde formula and the first order phase transition.

Permeation of high pressure CO2 in semicrystalline polymers
Creators: name: Hu, Tianyi
Publisher: name: Imperial College London
Year: 2021

description: With climate change becoming a major global concern, carbon capture and storage (CCS) has been the subject of intense research activity around the world. Although the benefits of CCS have been well recognised for decades, extensive industrial applications have not been realised. Particularly, there is a gap in research on the handling of high pressure CO2, despite the abundant work dealing with lower pressure CO2. This thesis focuses on the permeation process of CO2 through semicrystalline polymeric materials under high pressures, to gain a better understanding on the diffusion and sorption mechanisms in the CO2-polymer systems. The work presented in this thesis provides fundamental data, which could be used to guide the selection of suitable polymeric seals and liners in CCS applications, and may also be applied to other permeation-related processes involving CO2-polymer systems under high pressures. This thesis develops new experimental and modelling techniques to investigate the permeation behaviour of CO2 through semicrstalline polymers under high pressures. (i) An experimental setup for permeation measurements was designed and constructed. (ii) Continuous permeation experiments of CO2 in two commonly used semicrystalline polymers, polytetrauoroethylene (PTFE) and high density polyethelene (HDPE), were carried out at various temperatures ranging from 28 to 50 °C and pressures up to 600 bar. (iii) The experimental data was fitted to a diffusion model, which incorporated the free volume theory to describe the concentration-dependence of the diffusivity. The model was first nondimensionalised, and then simplified using assumptions, which were subsequently shown to be valid. A simple graphical method, which requires no numerical equation solvers, was proposed for model validation and parameter estimation. The obtained results were in excellent agreement with those obtained with the numerical solver. (iv) The effect of pressure on diffusion was characterised from the near-instantaneous flux drops, which were observed when the pressure was increased following steady states of permeation. (v) The solubilities derived from the permeation measurements were fitted to the Sanchez-Lacombe equation of state, and excellent fits were obtained between the two. On the basis of the experimental and modelling results, transport properties and free-volume parameters were successfully estimated; these were compared with data found in the literature under similar conditions.

description: The icy moons are in the focus of the exploration plans of the leading space agencies because of the indications of water-based life and geological activity observed in a number of these objects. In particular, the presence of geyser-like jets of water near Enceladus' south pole has turned this moon of Saturn into a priority candidate to search for life and habitability features. This investigation proposes a set of trajectories between Halo orbits about Lagrangian points L1 and L2 in the Saturn-Enceladus Circular Restricted Three-Body Problem as science orbits for a future in situ mission at Enceladus. The design methodology is presented, followed by the analysis of the observational performance of the solutions. The conclusion is that the proposed orbits exhibit suitable features for their use in the scientific exploration of Enceladus, i.e., long transfer times, low altitudes, wide surface visibility windows and long times of overflight.

description: Commodity program changes, such as planting flexibility, are estimated to achieve some net aggregate reductions in agrichemical use and erosion, while improving agriculture's market orientation and lowering government cost. However, the potential environmental effects vary widely by region. Although commodity program alteration can lessen some undesirable environmental effects in the short term, it does not remedy the basic externality causes of environmental problems. New land retirement approaches targeted to wetlands restoration and to land use change for water quality and other environmental services can achieve longrun environmental improvement. The net effects of land retirement on environmental quality, food and fiber production, consumer price, and government cost depend on simultaneous commodity program management. Any effects on commodities or the environment ultimately depend also on a host of external conditions (such as trade flows) affecting relative crop prices_ and input costs.

description: We highlight what seems to be a remaining subtlety in the argument for the cancellation of the total anomaly associated with the M5-brane in M-theory. Then we prove that this subtlety is resolved under the hypothesis that the C-field flux is charge-quantized in the generalized cohomology theory called J-twisted Cohomotopy.

description: Although Waldorf education resonates remarkably with Islamic life practice on several levels, the number of children from Muslim families is disproportionally small at Waldorf schools in Germany and the UK. This thesis aims to explore possible causes and collect incentives for addressing the matter in constructive ways. In order to establish how a Muslim approach to Waldorf education can be facilitated, it examines first some of the congruities, then the obstacles, supported by a survey among practising Muslim parents and finally the possibilities, illustrated by examples of trailblazers in Cambridge, Luxor and Los Angeles. Main merits of Waldorf education from a Muslim viewpoint were found in its holistic teaching approach, which takes into account not only children’s intellectual and physical development but also their spiritual and artistic unfolding. Several aspects became apparent which, once addressed, can make Waldorf education more accessible for Muslims and thereby respond to the recent resolve for a conscious renewal within the Waldorf movement.
