description: The meeting of Indian custom and law with the emergent formal legal, revenue and administrative practice of the British East India Company has long been a central subject of South Asian historical studies. Overwhelmingly, this vast corpus of scholarship has been centred on and contextualized by the experience and conditions of the Indian heartlands. This thesis takes the study of the meeting of local custom with the Company’s formal governmental practices out of the Indian heartlands up into the peripheral Himalayan region of Kumaon. Kumaon is the little patch of the Himalaya tucked up where today India, Nepal and Tibet all meet in a tangle of green hills, plunging valleys and icy peaks to the northeast of Delhi. The contrast of the region’s mountainous landscape to the awesome flatness of the adjacent North Indian plains could not be more extreme. Within Kumaon’s very different landscape, the population had remained light and widely scattered, a monetized economy based on specialization of production focused on urban centres had only emerged to a limited degree, and the people had persisted with and developed cultural practices that were distant and distinct from the orthodoxies of India’s heartland. Crucially, the Indo-Islamic empires of the plains had never been able to conquer and hold territory in these hills and, as a consequence, the region had had no experience with the legal, revenue and administrative practices of the Mughal empire. The British East India Company invaded and held Kumaon in 1815. Here they found a matrix of economic, political and cultural conditions very different from everything they knew from the plains below. Aware that its regulations—the embodiment of its formal governmental practices—were a palimpsest written on the pre-existing conditions of the plains and the vestiges of late-Mughal machinery of government, the Company chose not to impose its regulations in Kumaon. Rather, Kumaon would be an Extra-Regulation province where much of the everyday practices of government were in the hands of the local Commissioner. Within this space beyond the regulations, the meeting of local custom and the Company’s formal governmental practices took on a trajectory that was distant and distinct to the trajectory of the meeting on the plains. This thesis brings to light the early years of Kumaon's meeting with the practices of the British India Company in the period 1815 to 1843.

description: We report here on serendipitous observations of the intense gamma-ray flare from SGR 1806-20 that occured on 27 December 2004. Unique data from the Cluster and Double Star-2 satellites, designed to study the Earth's magnetosphere, provide the first observational evidence of three separate timescales within the early (first 100ms) phases of this class of events. These observations reveal that, in addition to the initial very steep (<0.25ms) X-ray onset, there is firstly a 4.9ms exponential rise timescale followed by a continued exponential rise in intensity on a timescale of 70ms. These three timescales are a prominent feature of current theoretical models including the timescale (several ms) for fracture propagation in the crust of the neutron star.

description: In the past twenty years the growth of China's economy and agriculture has been extraordinary. However it seems unlikely that, without substantial interventions, China will attain self-sufficiency in agriculture by 2005. We build a CGE model to examine the main trade policy options available to Chinese policy makers. We compare the welfare effects of each policy and explore the potential of biotechnology for agricultural productivity increase.

description: A long-standing question in active galactic nucleus (AGN) research is how the corona is heated up to produce X-ray radiation much stronger than that arising from the viscous heating within the corona. In this paper, we carry out detailed investigations of magnetic-reconnection heating to the corona, specifically, studying how the disc and corona are self-consistently coupled with the magnetic field, and how the emergent spectra depend on the fundamental parameters of AGN. It is shown that diverse spectral shapes and luminosities over a broad bandpass from optical to X-ray can be produced from the coupled disc and corona within a limited range of the black hole mass, accretion rate and magnetic field strength. The relative strength of X-ray emission with respect to optical/ultraviolet (UV) depends on the strength of the magnetic field in the disc, which, together with accretion rate, determines the fraction of accretion energy transported and released in the corona. This refined disc-corona model is then applied to reproduce the broad-band spectral energy distributions (SEDs) of a sample of 20 bright local AGNs observed simultaneously in X-ray and optical/UV. We find that, in general, the overall observed broad-band SEDs can be reasonably reproduced, except for rather hard X-ray spectral shapes in some objects. The radiation pressure-dominant region, as previously predicted for the standard accretion disc in AGN, disappears for strong X-ray sources, revealing that AGN accretion discs are indeed commonly stable as observed. Our study suggests the disc-corona coupling model involving magnetic fields to be a promising approach for understanding the broad-band spectra of bright AGNs.

description: Charge ordering behavior is observed in the crystal prepared through the immersion of the $Na_{0.41}CoO_2$ crystal in distilled water. Discovery of the charge ordering in the crystal with Na content less than 0.5 indicates that the immersion in water brings about the reduction of the $Na_{0.41}CoO_2$. The formal valence of Co changes from +3.59 estimated from the Na content to +3.5, the same as that in $Na_{0.5}CoO_2$. The charge compensation is confirmed to arise from the intercalation of the oxonium ions as occurred in the superconducting sodium cobalt oxide bilayer-hydrate.\cite{takada1} The charge ordering is the same as that observed in $Na_{0.5}CoO_2$. It suggests that the Co valence of +3.5 is necessary for the charge ordering.

description: The aim of the study is to determine the repellent property of active ingredient and dose response relationship of mustard oil against Anopheles stephensi. It is the major vector of malaria in urban as well as rural areas of Rajasthan. Five variables of mustard oil were tested against adults of Anopheles stephensi in laboratory conditions maintaining the temperature of 27±30 °C and 70±80% Relative Humidity. Active ingredient were mixed with acetone in different ratios and tested to identify the effective dose range. The concentration were chosen two showing less than 50% spatial repellency response and two showing greater than 50% spatial repellency response excluding 0% and 100% response. For treated 1.5 ml of the repellent active ingredient (acetone and mustard oil) was applied on Whatman filter paper 1 and in other control only diluents was applied in the spatial repellency assay unit. Twenty 3-4 day old adults of Anopheles stephensi were introduced into the central clear cylinder with the help of aspirator and kept for 30 seconds to acclimatize the environment. Spatial activity index (SAI) for each replicate was calculated using the formula and the mean index of each active ingredient dose was analysed by Probit Plane Regression Analysis from which ED50, ED90, ED99 and Carl Pearson Coefficient of Correlation can be estimated. The utility of the mustard oil against the test insect showed repellent behaviour efficiently.

description: We introduce and study a simplification of the symmetric single-impurity Kondo model. In the Ising-Kondo model, host electrons scatter off a single magnetic impurity at the origin whose spin orientation is dynamically conserved. This reduces the problem to potential scattering of spinless fermions that can be solved exactly using the equation-of-motion technique. The Ising-Kondo model provides an example for static screening. At low temperatures, the thermodynamics at finite magnetic fields resembles that of a free spin-1/2 in a reduced external field. Alternatively, the Curie law can be interpreted in terms of an antiferromagnetically screened effective spin. The spin correlations decay algebraically to zero in the ground state and display commensurate Friedel oscillations. In contrast to the symmetric Kondo model, the impurity spin is not completely screened, i.e., the screening cloud contains less than a spin-1/2 electron. At finite temperatures and weak interactions, the spin correlations decay to zero exponentially with correlation length $ξ(T)=1/(2πT)$.

description: We present results of the multicolour UBVR photometry of the high-amplitude EC14026-type star, Balloon 090100001. The data span over a month and consist of more than a hundred hours of observations. Fourier analysis of these data led us to the detection of at least 30 modes of pulsation of which 22 are independent. The frequencies of 13 detected modes group in three narrow ranges, around 2.8, 3.8 and 4.7 mHz, where the radial fundamental mode, the first and second overtones are likely to occur. Surprisingly, we also detect 9 independent modes in the low-frequency domain, between 0.15 and 0.4 mHz. These modes are typical for pulsations found in PG1716+426-type stars, discovered recently among cool B-type subdwarfs. The modes found in these stars are attributed to the high-order g modes. As both kinds of pulsations are observed in Balloon 090100001, it represents a link between the two classes of pulsating hot subdwarfs. At present, it is probably the most suitable target for testing evolutionary scenarios and internal constitution models of these stars by means of asteroseismology. Three of the modes we discovered form an equidistant frequency triplet which can be explained by invoking rotational splitting of an $\ell$ = 1 mode. The splitting amounts to about 1.58 $μ$Hz, leading to a rotation period of 7.1 $\pm$ 0.1 days.

description: Lewis acids like tris(pentafluorophenyl)borane (BCF) offer promising routes for efficient $p$-doping of organic semiconductors. The intriguing experimental results achieved so far call for a deeper understanding of the underlying doping mechanisms. In a first-principles work, based on state-of-the-art density-functional theory and many-body perturbation theory, we investigate the electronic and optical properties of donor/acceptor complexes formed by quarterthiophene (4T) doped by BCF. For reference, hexafluorobenzene (C$_6$F$_6$) and BF$_3$ are also investigated as dopants for 4T. Modelling the adducts as bimolecules \textit{in vacuo}, we find negligible charge transfer in the ground state and frontier orbitals either segregated on opposite sides of the interface (4T:BCF) or localized on the donor (4T:BF$_3$, 4T:C$_6$F$_6$). In the optical spectrum of 4T:BCF, a charge-transfer excitation appears at lowest-energy, corresponding to the transition between the frontier states, which exhibit very small but non-vanishing wave-function overlap. In the other two adducts, the absorption is given by a superposition of the features of the constituents. Our results clarify that the intrinsic electronic interactions between donor and acceptor are not responsible for the doping mechanisms induced by BCF and related Lewis acids. Extrinsic factors, such as solvent-solute interactions, intermolecular couplings, and thermodynamic effects, have to be systematically analyzed for this purpose.

description: As growth in world trade outpaces the growth in world Gross Domestic Product (GDP), economies are becoming ever more linked through world markets (Helpman, 1998). It is evident that U.S. agriculture is also becoming increasingly affected by changes or economic shocks in world markets and that this response is conditional on the response of other sectors with which it must compete for economy-wide resources. This paper links the U.S. agricultural sector with its bilateral trading partners by deriving "shock transmission functions". These functions link the direct effects of world economic shocks to the price of four U.S. (export) commodities namely meat, dairy, grains and crops. We derive a price equation that is a function of the product of income between the United States and it's trading partner among other explanatory variables. The coefficient estimates from these equations can be interpreted as price transmission elasticities. These elasticities are used to conduct policy experiments.

description: The large field-of-view of the Sun Watcher using Active Pixel System detector and Image Processing (SWAP) instrument on board the PRoject for Onboard Autonomy 2 (PROBA2) spacecraft provides a unique opportunity to study extended coronal structures observed in EUV in conjunction with global coronal magnetic field simulations. A global non-potential magnetic field model is used to simulate the evolution of the global corona from 1 September 2014 to 31 March 2015, driven by newly emerging bipolar active regions determined from Helioseismic and Magnetic Imager (HMI) magnetograms. We compare the large-scale structure of the simulated magnetic field with structures seen off-limb in SWAP EUV observations. In particular, we investigate how successful the model is in reproducing regions of closed and open structures; the scale of structures; and compare the evolution of a coronal fan observed over several rotations. The model is found to accurately reproduce observed large-scale off-limb structures. When discrepancies do arise they mainly occur off the east solar limb due to active regions emerging on the far side of the Sun, which cannot be incorporated into the model until they are observed on the Earth-facing side. When such ``late'' active region emergences are incorporated into the model, we find that the simulated corona self-corrects within a few days, so that simulated structures off the west limb more closely match what is observed. Where the model is less successful, we consider how this may be addressed, through model developments or additional observational products.

The corresponding experimental data lie on two straight lines which appear as a result of a sudden change in the nuclear shape marking two regions of deformation independently of the angular momentum of the outgoing proton. This feature provides a powerful tool to assign experimentally quantum numbers in proton emitters.

Seeing green in cyberspace : dynamic environmental information systems to support planning
Creators: name: Morgan, Katherine Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines an emerging class or category of web sites, termed dynamic environmental information systems (DEIS), and how they might support and enhance planning in general and environmental planning in particular. It describes the current planning context as planning in the face of complexity. Literature from complex adaptive systems theory and communicative planning theory is used to characterize the qualities and strategies suggested for communication in this context of complexity. A DEIS should incorporate diversity, share and build knowledge through discursive interaction, promote learning and change, emphasize the local over the global, and break down barriers between public and private. Two interrelated strategies a DEIS should support are gatherings and group processes, and relationships and relationship building. These factors should both guide and be reflected in the development of an information system to support communicative planning in the face of complexity. Emerging, Web-based information systems offer capabilities and features that can complement these theoretical factors. The features of database support, remote contribution and administration, and integration with other communication systems, media and technologies are examined. With this theoretical case for effectively exploiting new technology for planning purposes, the idea is explored from a practical perspective by undertaking a series of web-site development contracts. This combination of theoretical and experiential understanding of DEIS is used to create a framework to characterize elements of this approach. The framework is used to show readers examples of DEIS in practice and describe the sites in a systematic and consistent manner. Finally, I return to the theoretical factors to summarize the apparent state-of-the art for DEIS in practice. I conclude that this tool does serve to enhance and support the qualities and strategies of planning in the face of complexity and its demand for more communicative processes. This finding is qualified though by recommending further research on marketing to diverse target audiences, learning and change, and the organizational sustainability of DEIS themselves. The implications of DEIS for planners and other environmental change agents are a challenge to the profession to actively engage in developing this tool's potential and helping shape it to serve the goals of planning.

UNITED STATES OF AMERICA – Mississippi • 175 isolated teeth; Catahoula Formation; SC 2013.28.565 to 28.571, SC 2013.28.572 (Fig. 25L–N), SC 2013.28.573 (2 teeth), SC 2013.28.574 (101 teeth), SC 2013.28.575 (50 teeth), SC 2013.28.576 (14 teeth).
Description
The teeth are broadly triangular, with larger specimens measuring 11 mm in apico-basal height and 7 mm in width (antero-posterior). The labial and lingual crown faces are convex, but the lingual face, particularly near the base, is more so. In anterior/posterior view, the crown is medially curved but may be straight (Fig. 25M). The anterior and posterior margins are formed into smooth, sharp, convex cutting edges, and in labial view these edges converge to a rounded apex. It appears that enameloid once covered the crown surface, but this is generally only preserved at the cutting edges of the teeth in our sample. In basal view, the tooth has a thin D-shaped outline, and the basal surface is flat to weakly concave (Fig. 25N).
Remarks
The teeth described above are similar to Sphyraena sp. non-laniary teeth (see above) but can be differentiated by their thicker crown that is asymmetrical in basal view (compare Fig. 25N to 25F). The lingual face of Scomberomorus sp. teeth is much more convex than the labial face, and the crown is more medially curved. In contrast, the Sphyraena sp. crown is thinner, straighter (in carinal view), and the labial and lingual crown faces are slightly but equally convex. The teeth of Scomberomorus sp. differ from those of? Acanthocybium sp. (see above) by their labio-lingually thinner crown (compare Fig. 25N to K) and primarily flat basal surface. Although two species of Scomberomorus have been identified from Eocene deposits in Alabama (see Ebersole et al. 2019), the teeth in our sample represent the first occurrence of this taxon within any Oligocene strata in the Gulf Coastal Plain of the USA.

description: We study sample complexity of optimizing "hill-climbing friendly" functions defined on a graph under noisy observations. We define a notion of convexity, and we show that a variant of best-arm identification can find a near-optimal solution after a small number of queries that is independent of the size of the graph. For functions that have local minima and are nearly convex, we show a sample complexity for the classical simulated annealing under noisy observations. We show effectiveness of the greedy algorithm with restarts and the simulated annealing on problems of graph-based nearest neighbor classification as well as a web document re-ranking application.

description: Consolidations and spin-offs in the agricultural biotechnology industry and the growing links of multinational corporations with the food and feed industry have been the subject of considerable discussion among academics, policy makers, consumers, and farmers. Most of the research by academic and overnment institutions has focused on the reasons for consolidation. Little theoretical or empirical research has examined the impact of this consolidation. We adapt an endogenous growth model of industry structure and R&D to agricultural biotechnology and empirically estimate the model. These empirical estimates, the main focus of the paper, indicate that industry consolidation influences the amount and direction of research, which then feeds back to influence industry structure.

description: In various areas of modern physics and in particular in quantum gravity or foundational space-time physics it is of great importance to be in the possession of a systematic procedure by which a macroscopic or continuum limit can be constructed from a more primordial and basically discrete underlying substratum, which may behave in a quite erratic and irregular way. We develop such a framework within the category of general metric spaces by combining recent work of our own and ingeneous ideas of Gromov et al, developed in pure mathematics. A central role is played by two core concepts. For one, the notion of intrinsic scaling dimension of a (discrete) space or, in mathematical terms, the growth degree of a metric space at infinity, on the other hand, the concept of a metrical distance between general metric spaces and an appropriate scaling limit (called by us a geometric renormalisation group) performed in this metric space of spaces. In doing this we prove a variety of physically interesting results about the nature of this limit process, properties of the limit space as e.g. what preconditions qualify it as a smooth classical space-time and, in particular, its dimension.

description: The degree of vertical integration in the U.S. sugar industry between raw sugar processing and sugar refining cannot be explained using theories of vertical integration based on transaction costs (e.g. Williamson). We graphically decompose the economic rents accruing to each level in the marketing channel. Different strategies of several major sugar producing, processing and refining entities with regard to sugar quota policy are explored.

description: Establishing the neutrino mass hierarchy is one of the fundamental questions that will have to be addressed in the next future. Its determination could be obtained with long-baseline experiments but typically suffers from degeneracies with other neutrino parameters. We consider here the NOvA experiment configuration and propose to place a second off-axis detector, with a shorter baseline, such that, by exploiting matter effects, the type of neutrino mass hierarchy could be determined with only the neutrino run. We show that the determination of this parameter is free of degeneracies, provided the ratio L/E, where L the baseline and E is the neutrino energy, is the same for both detectors.

description: The New South Wa1es Milk Board was brought into being in 1929, as a result of producer action, to bring order into a highly disorganised market situation. The retailing of milk had been extremely competitive, milk supply and hence milk price had been erratic and hygiene had been a matter of caveat emptor. (1) The Board was without effective powers until the Milk Act, 1931, after which prices were stabilised, inspection of dairies was introduced and in general reasonable standards of hygiene were established. Initially whole milk quotas were allocated to factories. However, in the early 1950's it was found that despite a marked expansion of the milk zone, and despite a marked increase in price, the factory quota system still failed to produce sufficient winter milk. In 1955 individual farm quotas were introduced. A farmer's quota was determined by the zone in which he lived, and his level of winter milk production. In 1958 the quota system was altered again, in response to the discovery that a shortage of milk could occur at almost any time of the year. We will first discuss in detail certain shortcomings of current Milk Board operations; suggestions for improvement will be made. "Classical" and "quota" suggestions will be offered. The formal classical analysis will, of course, rely on the use of prices. The other suggestions will rely on an improved quota system supported by prices.
Evidence for magnetic activity at starbirth: a powerful X-ray flare from the Class 0 protostar HOPS 383

description: Context. Class 0 protostars represent the earliest evolutionary stage of solar-type stars, during which the majority of the system mass resides in an infalling envelope of gas and dust and is not yet in the central, nascent star. Although X-rays are a key signature of magnetic activity in more evolved protostars and young stars, whether such magnetic activity is present at the Class 0 stage is still debated. Aims. We aim to detect a bona fide Class 0 protostar in X-rays. Methods. We observed HOPS 383 in 2017 December in X-rays with the Chandra X-ray Observatory ($\sim$84 ks) and in near-infrared imaging with the Southern Astrophysical Research telescope. Results. HOPS 383 was detected in X-rays during a powerful flare. This hard (E > 2 keV) X-ray counterpart was spatially coincident with the northwest 4 cm component of HOPS 383, which would be the base of the radio thermal jet launched by HOPS 383. The flare duration was $\sim$3.3 h; at the peak, the X-ray luminosity reached $\sim$4 x 1E31 erg s --1 in the 2-8 keV energy band, a level at least an order of magnitude larger than that of the undetected quiescent emission from HOPS 383. The X-ray flare spectrum is highly absorbed (NH $\sim$ 7 x 1E23 cm --2), and it displays a 6.4 keV emission line with an equivalent width of $\sim$1.1 keV, arising from neutral or low-ionization iron. Conclusions. The detection of a powerful X-ray flare from HOPS 383 constitutes direct proof that magnetic activity can be present at the earliest formative stages of solar-type stars.

description: Wool may be classed (i.e., grouped into reasonably uniform lots prior to sale) either immediately after shearing in the shearing shed or it may be packed into bales and sent to a wool store for classing. The second type of operation (especially when applied to relatively small quantities of wool) is known as bulk classing. With bulk classing the individual grower's wool loses its identity and is offered for sale in mixed lots. There are a number of other methods of preparation of wool for sale. Of these the only one which will be considered here specifically is "interlotting" which consists of shed classed bales from a number of growers being matched and sold as one lot. Interlotting is purely an operation to increase the size of lots (i.e., the number of bales per lot sold) so as to attract more competition from buyers or to reduce the valuing, inspection and bidding work of buyers and others

description: Within the profession of agricultural economics are found academics, government economists, farm organization economists, and others. Although the profession is based on general acceptance of principles and judgements, the outlook and activities of an individual are conditioned by his occupational status. Employment affiliations give rise to certain restraints and strains to communication between functional groups. The paper examines this problem, and presents a case for better understanding between the major institutional groups.

description: The potential effects of a uniform meat grading scheme on market performance are evaluated in terms of a change in the information state. A uniform grading system may reduce the per unit costs involved in the collection and transmission of information on the characteristics of, and the price differentials for, different units of the commodity set. Under conditions of uncertainty an improved information state will increase market participants' expected utility. A general procedure for an empirical evaluation of a grading scheme is outlined.

description: Modeling and simulating movement of vehicles in established transportation infrastructures, especially in large urban road networks is an important task. It helps with understanding and handling traffic problems, optimizing traffic regulations and adapting the traffic management in real time for unexpected disaster events. A mathematically rigorous stochastic model that can be used for traffic analysis was proposed earlier by other researchers which is based on an interplay between graph and Markov chain theories. This model provides a transition probability matrix which describes the traffic's dynamic with its unique stationary distribution of the vehicles on the road network. In this paper, a new parametrization is presented for this model by introducing the concept of two-dimensional stationary distribution which can handle the traffic's dynamic together with the vehicles' distribution. In addition, the weighted least squares estimation method is applied for estimating this new parameter matrix using trajectory data. In a case study, we apply our method on the Taxi Trajectory Prediction dataset and road network data from the OpenStreetMap project, both available publicly. To test our approach, we have implemented the proposed model in software. We have run simulations in medium and large scales and both the model and estimation procedure, based on artificial and real datasets, have been proved satisfactory. In a real application, we have unfolded a stationary distribution on the map graph of Porto, based on the dataset. The approach described here combines techniques whose use together to analyze traffic on large road networks has not previously been reported.

description: The consequences of carryover for the optimal application of fertilizer are considered using dynamic programming. The conclusions are relevant for the further problem of deciding how many grain crops to harvest from grain sorghum plants grown in a tropical environment. Dynamic programming is also used for solving this problem for the Ord River Valley, and takes account of the interrelations between season and crop cycle number. Data were obtained from investigations conducted in the area.

description: A simple model of the cereal harvest operation was constructed for the Wimmera region of Victoria. The model was used to investigate factors influential in determining the harvesting costs of a machinery system over a period of years. An evaluation of alternative machinery systems was also conducted using the model. The superiority of systems simulation over static analysis was demonstrated by using the model to incorporate stochastic variables and to handle the dynamic nature of the harvest operation. In addition, the model output was shown to provide more information for decision makers than had resulted from previous Australian studies. It was concluded that systems simulation is an appropriate technique for investigating farm management machinery selection problems.
Statistical Zero Knowledge and quantum one-way functions

description: One-way functions are a very important notion in the field of classical cryptography. Most examples of such functions, including factoring, discrete log or the RSA function, can be, however, inverted with the help of a quantum computer. In this paper, we study one-way functions that are hard to invert even by a quantum adversary and describe a set of problems which are good such candidates. These problems include Graph Non-Isomorphism, approximate Closest Lattice Vector and Group Non-Membership. More generally, we show that any hard instance of Circuit Quantum Sampling gives rise to a quantum one-way function. By the work of Aharonov and Ta-Shma, this implies that any language in Statistical Zero Knowledge which is hard-on-average for quantum computers, leads to a quantum one-way function. Moreover, extending the result of Impagliazzo and Luby to the quantum setting, we prove that quantum distributionally one-way functions are equivalent to quantum one-way functions. Last, we explore the connections between quantum one-way functions and the complexity class QMA and show that, similarly to the classical case, if any of the above candidate problems is QMA-complete then the existence of quantum one-way functions leads to the separation of QMA and AvgBQP.
