description: Consumer attitudes towards genetically modified (GM) food are well documented but there has been much less focus on farmer attitudes to GM technology in agriculture. This paper reports findings from a study investigating farmers’ attitudes to GM crops in Scotland. Results from a Q methodology study reveal three discourses, one apparently pro-GM and demonstrating an expectation of benefits, the second representing a more uncertain position, wary of the potential risks of the technology but likely to be reluctant adopters, and the third describing a group who demonstrate a somewhat fatalistic attitude towards the issue of GM technology adoption and impact. The paper also reports findings from a postal survey conducted as part of the Q methodology study. Results from a scenario question suggest that the majority of Scottish farmers are unsure at this stage whether they would choose to adopt GM technology or not, opting instead for a ‘wait and see’ position. The intention (or not) to adopt, appears to be related to a number of variables such as type of crops grown, whether or not the farmer expects to pass on the farm to the next generation of the family, and whether the farmer thinks GM crops will be good or bad for Scottish agriculture. These findings contribute to the overall GM debate by providing some insight into the differing positions held by farmers in Scotland and thereby offering an indication of the likelihood of GM crops being introduced into the Scottish landscape.
Uniform Semiclassical Approach to Fidelity Decay: from Weak to Strong Perturbation

description: We study fidelity decay by a uniform semiclassical approach, in the three perturbation regimes, namely, the perturbative regime, the Fermi-golden-rule (FGR) regime, and the Lyapunov regime. A semiclassical expression is derived for fidelity of initial Gaussian wave packets with width of the order $\sqrt{\hbar}$ ($\hbar$ being the effective Planck constant). Short time decay of fidelity of initial Gaussian wave packets is also studied, with respect to two time scales introduced in the semiclassical approach. In the perturbative regime, it is confirmed numerically that fidelity has the FGR decay before the Gaussian decay sets in. An explanation is suggested to a non-FGR decay in the FGR regime, which has been observed in a system with weak chaos in the classical limit, by using the Levy distribution as an approximation for the distribution of action difference. In the Lyapunov regime, it is shown that the average of the logarithm of fidelity may have roughly the Lyapunov decay within some time interval, in systems possessing large fluctuation of the finite-time Lyapunov exponent in the classical limit.

description: This paper is concerned with how communities are constructed symbolically and the relation between such symbolically constructed communities and communities-ofplace. Analysis of literature on the symbolic construction of Scottish communities shows that the boundaries of these communities do not necessarily coincide with the boundaries of the geographically defined community-of-place. People identify, and are identified, with more than one community, and such identification is temporary in character. Which community is identified with is dependent on the specific time, place, group of people and activities engaged in.
Crucial role of neutron diffusion in the crust of accreting neutron stars

description: Observed temperatures of transiently accreting neutron stars in the quiescent state are generally believed to be supported by deep crustal heating, associated with non-equilibrium exothermic reactions in the crust. Traditionally, these reactions are studied by considering nuclear evolution governed by compression of the accreted matter. Here we show that this approach has a basic weakness, that is that in some regions of the inner crust the conservative forces, applied for matter components (nuclei and neutrons), are not in mechanical equilibrium. In principle the force balance can be restored by dissipative forces, however the required diffusion fluxes are of the same order as total baryon flux at Eddington accretion. We argue that redistribution of neutrons in the inner crust should be involved in realistic model of accreted crust.

description: Carreras, Dobson and colleagues have studied empirical data on the sizes of the blackouts in real grids and modeled them by computer simulations using the direct current approximation. They have found that the resulting blackout sizes are distributed as a power law and suggested that this is because the grids are driven to the self-organized critical state. In contrast, more recent studies found that the distribution of cascades is bimodal as in a first order phase transition, resulting in either a very small blackout or a very large blackout, engulfing a finite fraction of the system. Here we reconcile the two approaches and investigate how the distribution of the blackouts change with model parameters, including the tolerance criteria and the dynamic rules of failure of the overloaded lines during the cascade. In addition, we study the same problem for the Motter and Lai model and find similar results, suggesting that the physical laws of flow on the network are not as important as network topology, overload conditions, and dynamic rules of failure.

description: The recreational site choice decision modeled in most economic analyses seldom contains previous experience with the site as a characteristic or attribute. A rational dynamic model is used to incorporate previous experience with the site in a model of the choice of recreation sites. Based on the comparison of dynamic and static models, it is apparent that dynamic elements influence choice. The use of previous consumption as an attribute (either in a naïve or rational form) is an improvement over static models of choice. In welfare analysis, this effect may be a significant factor. For example, a change in prices or quality attributes may have a much larger impact on those individuals who have developed habits.

description: In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous. The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for linking econometric production analysis to the time-specific analyses in other scientific disciplines used to assess the environmental or human health impacts of agricultural production practices. The case study of fungicide use on Ecuadorian potatoes was conducted with a unique data set containing detailed information on both quantity and timing of input use. The results showed that both quantity and timing of chemical use were responsive to economic variables.

description: Mesocixiodes Tillyard, 1922
 Mesocixiodes Tillyard, 1922: 462.
 Type species. Mesocixiodes termioneura Tillyard, 1922, by original designation.
 Emended diagnosis. Tegmen c. 3.5 times longer than wide, finely to somewhat coarsely punctate and tending to irregularly transversely rugose, extreme apical area possibly less so; costal margin broadly rounded, apex narrowly rounded; peripheral membrane of even width; costal space c. 3 times as wide as medial cell; R and M separating near apex of basal cell; basal cell quite broad proximally, slightly tapering and closed distally by a fusion for a short length of M and CuA; primary fork of R just before tegmen length, far basal to primary fork of M which is well beyond primary fork of RA and just proximal to very shallow CuA fork; RA 1 simple, obliquely angled towards anterior margin; RA 2 stem directed apically, more or less parallel with costal margin, with 4 or 5 long, sub-equal pectinate branches directed antero-apically; RA 1 + RA 2 field occupying entire antero-apical margin; RP deeply forked; one ir, running from RA 2 to RP 1; RP 2 fused with M 1+2 for a short length (RK1 and RK2), or separate, with a single r-m, in line with ir (holotype); M with 4 or 5 branches; im between M 2 and M 3 or M 3+4;intra-medial cell quite broad but very small, c. 2 times longer than wide, occupying a very small portion of post-nodal area; CuA branches short, CuA 1 strongly angled at m-cua which joins M 3+4 around midpoint of intra-medial cell; crossvein field tending to alignment at level of claval apex, thus creating a fairly even series of long, sub-equal apical cells; clavus not preserved.
 Notes. Mesocixiodes was placed by Tillyard (1922, 1926), Becker-Migdisova (1962a), and Jell (2004) in Cixiidae (Fulgoroidea), by Handlirsch (1939) in Fulgoridae, by Evans (1956) in Chiliocyclidae, and was considered by Carpenter (1992) as ‘Family uncertain’. It was transferred to Hylicellidae by Hamilton (1992). It differs from all other hylicellids in the very late forking of M, well distal of that of RA, the very small intra-medial cell, and the tendency to alignment of the crossvein field at the claval apex to create a fairly even series of long, sub-equal apical cells.

description: Baryons with a heavy c-quark or a heavy b-quark and also two c-quarks have been discovered. These states are expected in QCD and therefore provide a test for the theory. There should be double beauty baryons, and also an intriguing possibility that baryons ${\bf B}_{bc}$ with a c-quark, a b-quark. These states are yet to be discovered. The main decay modes of ${\bf B}_{bc}$ are expected to be weak processes from theoretical understanding of their mass spectrum. These decay modes can provide crucial information about these heavy baryons ${\bf B}_{bc}$. We analyze two body hadronic weak decays for ${\bf B}_{bc}$ using $SU(3)$ flavor symmetry. Any one of the $c$ and $b$ decays will induce ${\bf B}_{bc}$ to decay. We find that the Cabibbo allowed decays ${\bf B}_{bc} \to {\bf B}_b + M$ due to $c \to s u \bar d$ can be crucial for exploration. The LHC may have the sensitivity to discover such decays. Other ${\bf B}_{bc}$ decays due to $b \to c q' \bar q$ are sub-leading. Several relations among branching ratios are obtained which can be used to test $SU(3)$ flavor symmetry.

description: The size of the Texas-Oklahoma spot market for the 1999/2000 marketing year increased considerably from the previous year and the average producer price declined for the fourth year in a row. The average price received by producers during the 1999/2000 marketing year was about 37.82 cents/lb., which was 13.32 cents/lb. lower than the previous marketing year. The 1999 crop was generally of good quality, but the average for staple length and strength declined compared to the 1998 crop. The percentage of bales having level 2 bark, and level 1 and 2 other extraneous matter also increased marginally when compared to the 1998 crop. With the exception of the first digit of the color grade, level 1 bark, and level 2 other extraneous matter, price discounts for the 1999 crop decreased for all quality attributes. The premiums for the first digit of the color grade and staple both increased, while the premium for strength decreased.
Learning for optimized provisioning of network resources
Creators: name: Chen, Zheyu
Publisher: name: Imperial College London
Year: 2024

description: This thesis focuses on developing novel learning techniques for resource provisioning in communication networks with the goal of identifying the optimal resource provisioning decisions. In this context, both the static and dynamic problem formulations are considered to investigate the impact of various resource restrictions and time evolution. Initially, we explore the static problem formulation that models the resource provisioning problems at different time instances as individually constrained optimization problems. To address the computational challenges of repeatedly solving these problems due to the time evolution (i.e., the changing system parameters), two Coupled Long Short-Term Memory networks (CLSTM) are proposed. Extensive numerical experiments using Alibaba datasets validate that the CLSTM can quickly produce the optimal solution over a range of system parameters in a few iterations during the inference (e.g., achieving 98% mean relative accuracy after 67 iterations), significantly reducing CPU time and iteration consumption compared with conventional gradient-based iterative algorithms. To incorporate time evolution and system dynamics, the thesis considers the dynamic problem formulation. As communication networks often demonstrate periodic temporal characteristics (e.g., periodic task arrivals), we model the resource provisioning problem as a periodic Markov Decision Process (pMDP). A model-free deep-learning method with a multi-policies solution framework is developed to address the lack of existing model-free algorithms for pMDPs. Evaluation results demonstrate the proposed technique outperforms the state-of-the-art deep reinforcement learning algorithm by 32% on average. To further improve the computational efficiency of applying the proposed multi-policies solution, we introduce the multi-MDP framework that allows a single policy to be used for non-uniform time durations, thus reducing the number of required policies. Our experimental results using the practical task arrivals from Alibaba reveal that the task utilities obtained using the proposed framework of sequential policies can yield an average improvement of 23% over those from a single-policy RL solution.

description: Magmatic segregation and volcanic eruptions transport tidal heat from Io's interior to its surface. Several observed eruptions appear to be extremely high temperature ($\geq$ 1600 K), suggesting either very high degrees of melting, refractory source regions, or large amounts of viscous heating on ascent. To address this ambiguity, we develop a model that couples crust and mantle dynamics to a simple compositional system. We analyse the model to investigate chemical structure and evolution. We demonstrate that magmatic segregation and volcanic eruptions lead to differentiation of the mantle, the extent of which depends on how easily high temperature melts from the more refractory lower mantle can migrate upwards. We propose that Io's highest temperature eruptions originate from this lower mantle region, and that such eruptions act to limit the degree of compositional differentiation.

description: We focus on quantization of the metric of a black hole restricted to the Killing horizon with universal radius $r_0$. After imposing spherical symmetry and after restriction to the Killing horizon, the metric is quantized employing the chiral currents formalism. Two ``components of the metric'' are indeed quantized: The former behaves as an affine scalar field under changes of coordinates, the latter is instead a proper scalar field. The action of the symplectic group on both fields is realized in terms of certain horizon diffeomorphisms. Depending on the choice of the vacuum state, such a representation is unitary. If the reference state of the scalar field is a coherent state rather than a vacuum, spontaneous breaking of conformal symmetry arises and the state contains a Bose-Einstein condensate. In this case the order parameter fixes the actual size of the black hole with respect to $r_0$. Both the constructed state together with the one associated with the affine scalar are thermal states (KMS) with respect to Schwarzschild Killing time when restricted to half horizon. The value of the order parameter fixes the temperature at the Hawking value as well. As a result, it is found that the quantum energy and entropy densities coincide with the black hole mass and entropy, provided the universal parameter $r_0$ is suitably chosen, not depending on the size of the actual black hole in particular.

description: The volume of the Texas-Oklahoma spot cotton market analyzed by the Daily Price Estimation System (DPES) for the 2001/02 marketing year increased from 222,283 bales the previous year to 364,267 bales this year. The average price received by producers during the 2001/02 marketing year was 26.8 cents/lb, which is considerably less than the previous year. The 2001 crop was generally of good quality. The average micronaire level was higher in 2001 at 4.41, and the average number of bales having level 1 bark was up in comparison to the 2000 crop. With the exception of strength, price discounts for the 2001 crop decreased for all quality attributes, coupled with a decrease in premiums. In regard to strength, producers did not appear to receive a premium for higher levels of strength while lower levels of strength were discounted more severely than the previous year.

description: The $n\to\infty$ continuum limit of super-Toda models associated with the affine $sl(2n|2n)^{(1)}$ (super)algebra series produces $(2+1)$-dimensional integrable equations in the ${\bf S}^{1}\times {\bf R}^2$ spacetimes. The equations of motion of the (super)Toda hierarchies depend not only on the chosen (super)algebras but also on the specific presentation of their Cartan matrices. Four distinct series of integrable hierarchies in relation with symmetric-versus-antisymmetric, null-versus-nonnull presentations of the corresponding Cartan matrices are investigated. In the continuum limit we derive four classes of integrable equations of heavenly type, generalizing the results previously obtained in the literature. The systems are manifestly N=1 supersymmetric and, for specific choices of the Cartan matrix preserving the complex structure, admit a hidden N=2 supersymmetry. The coset reduction of the (super)-heavenly equation to the ${\bf I}\times{\bf R}^{(2)}=({\bf S}^{1}/{\bf Z}_2)\times {\bf R}^2$ spacetime (with ${\bf I}$ a line segment) is illustrated. Finally, integrable $N=2,4$ supersymmetrically extended models in $(1+1)$ dimensions are constructed through dimensional reduction of the previous systems.

description: A land bid-price model is formulated which integrates asset pricing models form prior studies to illustrate the singular and joint effects of ordinary and capital gains taxes, growth of returns, diseconomies of size, and risk behavior on farmland prices. An application of the model to primary data from cash grains farms illustrates that the ceteris paribus effect of increased marginal tax rates on a perpetual, growing income stream is to increase its present value. Larger farms in higher marginal tax brackets are shown to have a competitive advantage over smaller, lower tax bracket farms.

description: Human-mediated introductions of non-native species are expected to increase globally and threaten native biodiversity. Lepomis auritus (Redbreast Sunfish), a carnivorous freshwater fish native to rivers in eastern North America, has been introduced far outside of its native range due to its popularity in recreational fisheries. However, poor documentation of introductions and lack of thorough ichthyofaunal surveys before the mid-20th century have complicated our understanding of the establishment and spread of non-native L. auritus over the past 90 years, precluding effective management. We conducted phylogenomic analyses using ddRAD data from 197 specimens of L. auritus collected throughout the known geographic range of the species to reconstruct the introduction history of the species. Our protocols allow for the reconstruction of complicated introduction routes and reveal that L. auritus in Texas is the result of a single-source introduction from the Suwannee River; the population in the upper Tennessee River has two sources of introduction from the Savannah River and the northeastern rivers that drain into the Atlantic Ocean; and the populations in the middle Tennessee River and the Mobile River Basin have sources from the upper Tennessee River system and the Apalachicola River Basin. Ecological and evolutionary investigations of the non-native populations of L. auritus will broaden the understanding of invasion dynamics in species of Lepomis and other non-native freshwater fishes in North America. Our study provides critical information for the conservation of native populations and invasive management of non-native populations of L. auritus.

description: As an explanation of regional economic growth, do "people follow jobs" or do "jobs follow people"? The current wisdom in the regional economics literature is that migration and employment change are jointly determined, but that the "jobs follow people" effect is the stronger of the two. Our evidence for selected counties in the Pacific Northwest from 1965 to 1970 does not support that argument. The problem may become increasingly difficult to model if the desire for non-market good, rather than income gains, continues to evolve as a major reason for migration.

description: Understanding and predicting the intention of pedestrians is essential to enable autonomous vehicles and mobile robots to navigate crowds. This problem becomes increasingly complex when we consider the uncertainty and multimodality of pedestrian motion, as well as the implicit interactions between members of a crowd, including any response to a vehicle. Our approach, Probabilistic Crowd GAN, extends recent work in trajectory prediction, combining Recurrent Neural Networks (RNNs) with Mixture Density Networks (MDNs) to output probabilistic multimodal predictions, from which likely modal paths are found and used for adversarial training. We also propose the use of Graph Vehicle-Pedestrian Attention Network (GVAT), which models social interactions and allows input of a shared vehicle feature, showing that inclusion of this module leads to improved trajectory prediction both with and without the presence of a vehicle. Through evaluation on various datasets, we demonstrate improvements on the existing state of the art methods for trajectory prediction and illustrate how the true multimodal and uncertain nature of crowd interactions can be directly modelled.

description: We study the Dp-brane dynamics near NS5-branes with constant electromagnetic field. In the framework of effective Dirac-Born-Infeld action, we investigate the effect of the electromagnetic field on the Dp-brane dynamics. The radial motion of the Dp-brane on the transverse directions of NS5-branes can be mapped to a rolling tachyon in a constant NS $B_{μν}$ background. In the near throat region, the classical motion can be identified with the rescaled hairpin. After constructing the boundary state of the rescaled hairpin, we discuss the closed string emission of the Dp-brane and find that the energy of the closed string emission is always finite in the presence of electric field. Taking winding strings into account, the emitted energy is divergent, indicating that the emitted winding strings carry away most of energy.

description: We analyse quantum field models of the bosenova experiment, in which $^{85}$Rb Bose-Einstein condensates were made to collapse by switching their atomic interactions from repulsive to attractive. Specifically, we couple the lowest order quantum field correlation functions to the Gross-Pitaevskii function, and solve the resulting dynamical system numerically. Comparing the computed collapse times with the experimental measurements, we find that the calculated times are much larger than the measured values. The addition of quantum field corrections does not noticeably improve the agreement compared to a pure Gross-Pitaevskii theory.

description: A rotation-vibration line list for the electronic ground state ($\tilde{X}^{1}A_{1}$) of SiH$_2$ is presented. The line list, named CATS, is suitable for temperatures up to 2000 K and covers the wavenumber range 0 - 10,000 cm$^{-1}$(wavelengths $>1.0$ $μ$m) for states with rotational excitation up to $J=52$. Over 310 million transitions between 593 804 energy levels have been computed variationally with a new empirically refined potential energy surface, determined by refining to 75 empirical term values with $J\leq 5$ and a newly computed high-level ab initio dipole moment surface. This is the first, comprehensive high-temperature line list to be reported for SiH$_2$ and it is expected to aid the study of silylene in plasma physics, industrial processes and possible astronomical detection. Furthermore, we investigate the phenomenon of rotational energy level clustering in the spectrum of SiH$_2$. The CATS line list is available from the ExoMol database (www.exomol.com) and the CDS database.

description: We present a controllable neural audio synthesizer based on Gaussian Mixture Variational Autoencoders (GM-VAE), which can generate realistic piano performances in the audio domain that closely follows temporal conditions of two essential style features for piano performances: articulation and dynamics. We demonstrate how the model is able to apply fine-grained style morphing over the course of synthesizing the audio. This is based on conditions which are latent variables that can be sampled from the prior or inferred from other pieces. One of the envisioned use cases is to inspire creative and brand new interpretations for existing pieces of piano music.

description: A 46-equation econometric model of the U.S. potato market was developed. The model examines the determination of planted acreage, yield, production, and farm prices in the Pacific Northwest and in five other producing regions which compete with Northwest production. National demand relationships for potatoes used in processing, fresh consumption and livestock feed are also specified. These estimated relationships are used to simulate future scenarios which assume alternative rates of expansion for Northwest potato production. Results suggest that opportunities for considerable expansion of Northwest potato production exist if the secular shift in potato demand continues and increases in acreage are not excessive or expansion does not occur too quickly.

description: To fluently collaborate with people, robots need the ability to recognize human activities accurately. Although modern robots are equipped with various sensors, robust human activity recognition (HAR) still remains a challenging task for robots due to difficulties related to multimodal data fusion. To address these challenges, in this work, we introduce a deep neural network-based multimodal HAR algorithm, HAMLET. HAMLET incorporates a hierarchical architecture, where the lower layer encodes spatio-temporal features from unimodal data by adopting a multi-head self-attention mechanism. We develop a novel multimodal attention mechanism for disentangling and fusing the salient unimodal features to compute the multimodal features in the upper layer. Finally, multimodal features are used in a fully connect neural-network to recognize human activities. We evaluated our algorithm by comparing its performance to several state-of-the-art activity recognition algorithms on three human activity datasets. The results suggest that HAMLET outperformed all other evaluated baselines across all datasets and metrics tested, with the highest top-1 accuracy of 95.12% and 97.45% on the UTD-MHAD [1] and the UT-Kinect [2] datasets respectively, and F1-score of 81.52% on the UCSD-MIT [3] dataset. We further visualize the unimodal and multimodal attention maps, which provide us with a tool to interpret the impact of attention mechanisms concerning HAR.

description: A complete analysis is presented for the far-field creeping flow produced by a multipolar force distribution in a fluid confined between two parallel planar walls. We show that at distances larger than several wall separations the flow field assumes the Hele-Shaw form, i.e., it is parallel to the walls and varies quadratically in the transverse direction. The associated pressure field is a two-dimensional harmonic function that is characterized by the same multipolar number m as the original force multipole. Using these results we derive asymptotic expressions for the Green's matrix that represents Stokes flow in the wall-bounded fluid in terms of a multipolar spherical basis. This Green's matrix plays a central role in our recently proposed algorithm [Physica A xx, {\bf xxx} (2005)] for evaluating many-body hydrodynamic interactions in a suspension of spherical particles in the parallel-wall geometry. Implementation of our asymptotic expressions in this algorithm increases its efficiency substantially because the numerically expensive evaluation of the exact matrix elements is needed only for the neighboring particles. Our asymptotic analysis will also be useful in developing hydrodynamic algorithms for wall-bounded periodic systems and implementing acceleration methods by using corresponding results for the two-dimensional scalar potential.

description: Several hedging strategies for fat cattle are compared using actual feedlot performance information for a period of 6.5 years and 747 pens of fat cattle. Results show that cattle feeding was not profitable (a $24.50 per head cash market loss) but a carefully chosen hedging strategy could have reduced the loss by 50 percent.
