description: We study differential and integral relations for the quantum Jost solutions associated with an integrable derivative nonlinear Schrodinger (DNLS) model. By using commutation relations between such Jost solutions and the basic field operators of DNLS model, we explicitly construct first few quantum conserved quantities of this system including its Hamiltonian. It turns out that this quantum Hamiltonian has a new kind of coupling constant which is quite different from the classical one. This modified coupling constant plays a crucial role in our comparison between the results of algebraic and coordinate Bethe ansatz for the case of DNLS model. We also find out the range of modified coupling constant for which the quantum $N$-soliton state of DNLS model has a positive binding energy.

description: Millimeter wave (mmWave)-enabled unmanned aerial vehicle (UAV) swarm networks (UAVSNs) can utilize a large spectrum of resources to provide low latency and high data transmission rate. Additionally, owing to the short wavelength, UAVs equipped with large antenna arrays can form secure narrow directive beam to establish communication with less interference. However, due to the high UAV mobility, limited beam coverage, beam misalignment, and high path loss, it is very challenging to adopt the mmWave communication in UAVSNs. In this article, we present a comprehensive survey on neighbor discovery and beam alignment techniques for directional communication in mmWave-enabled UAVSNs. The existing techniques are reviewed and compared with each other. We also discuss key open issues and challenges with potential research direction.

description: In this letter we show how the method of [4] for the calculation of two-point functions in d+1-dimensional AdS space can be simplified. This results in an algorithm for the evaluation of the two-point functions as linear combinations of Legendre functions of the second kind. This algorithm can be easily implemented on a computer. For the sake of illustration, we displayed the results for the case of symmetric traceless tensor fields with rank up to l=4.

description: There is evidence that the use of corn as a biofuels feedstock has increased the crude oil pass-through to the corn price. Changes in US biofuels policy can be seen as initially increasing and subsequently retarding the use of corn in ethanol production. Because the policy both mandates but also limits this use, different regimes can prevail depending on which constraints are binding. Structural break methods show that the pass-through was important over the four years 2003-07 but has subsequently been much more limited. Competitive storage theory continues to explain much of the price movement even over those four years.

description: This paper explores a management practice that increases average daily weight gain (ADG) in dairy heifers from three months of age until confirmed pregnancy. The practice achieves early maturation of the animal as heifers under this management start lactation at 22 months of age compared to 26 months under common farm practices. This practice is an efficient rearing process for dairy farms and is considered more environment-friendly. It is associated with reduced emissions of GHG due to a reduced need for maintenance feeding, as well as a lower demand for recruitment animals. The management practice implies higher daily feed costs, but there are lesser days of feeding and lower costs of housing and labour. The objective of this study is to explore the financial and environmental impacts of the ADG management practice on Norwegian dairy farms.
On the length expectation values in quantum Regge calculus

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Regge calculus configuration superspace can be embedded into a more general superspace where the length of any edge is defined ambiguously depending on the 4-tetrahedron containing the edge. Moreover, the latter superspace can be extended further so that even edge lengths in each the 4-tetrahedron are not defined, only area tensors of the 2-faces in it are. We make use of our previous result concerning quantisation of the area tensor Regge calculus which gives finite expectation values for areas. Also our result is used showing that quantum measure in the Regge calculus can be uniquely fixed once we know quantum measure on (the space of the functionals on) the superspace of the theory with ambiguously defined edge lengths. We find that in this framework quantisation of the usual Regge calculus is defined up to a parameter. The theory may possess nonzero (of the order of Plank scale) or zero length expectation values depending on whether this parameter is larger or smaller than a certain value. Vanishing length expectation values means that the theory is becoming continuous, here {\it dynamically} in the originally discrete framework.

description: Image monitoring and guidance during medical examinations can aid both diagnosis and treatment. However, the sampling frequency is often too low, which creates a need to estimate the missing images. We present a probabilistic motion model for sequential medical images, with the ability to both estimate motion between acquired images and forecast the motion ahead of time. The core is a low-dimensional temporal process based on a linear Gaussian state-space model with analytically tractable solutions for forecasting, simulation, and imputation of missing samples. The results, from two experiments on publicly available cardiac datasets, show reliable motion estimates and an improved forecasting performance using patient-specific adaptation by online learning.

description: Seed is an essential input in agriculture, and the availability of quality seed of superior varieties is often critical for improved food security and poverty reduction in developing countries like Nigeria. However, while the Nigerian government recognizes the importance of improving seed availability, its recent focus in the seed sector has mostly been on improving seed quality rather than on varietal development. This report argues that this is partly due to a knowledge gap regarding the relationship between varietal technology levels and the effectiveness of seed sector policies. We first provide a brief conceptual discussion on how the effectiveness of selected seed sector policies, such as certification, subsidies, and private sector promotion, may depend on underlying varietal technology levels. Using rice as an example, we then provide key historical and international perspectives on how varietal technology development by the public sector through intensive rice breeding had preceded the expansion of seed certification and testing, and show that there still is a substantial need for the Nigerian government to develop improved rice varieties through intensified domestic plant breeding in order for its seed certification and seed subsidy programs to be more effective.

description: The purpose of the following basis tables is to provide information on the historical cash-futures price relationships for selected North Carolina cash markets and Chicago futures markets. The basis for a particular pair of cash-futures markets allows an agricultural producer to convert a futures price for a given contract month into an expectation of the net price from a hedged position which would be received in the month the commodity is sold. This information is important for a hedger. Basis allows a potential hedger to forecast an expected net selling price, and then lock in the price through a futures market hedge if the price is attractive. Basis is generally defined as the cash minus the futures price. Thus, a negative basis implies a cash price which is below a futures price, while a positive basis implies a cash price above a futures price. A hedged price expectation for a market can be derived by adding the basis to the futures price. Basis estimates for grains (corn, soybeans, and wheat) are computed using weekly cash and futures prices. The cash prices are taken from the Market Grain Report, published weekly by the Market News Section, Division of Marketing, North Carolina Department of Agricultute, Futures prices are taken from The Wall Street Journal. Two basis tables are provided for each cash market; one provides a three-year average basis (19.86-1988) and the other provides a five-year average basis (1984-1988). Basis averages for each calendar month are calculated for futures contracts expiring up to one year into the future.

title: Explorations of Life in Several Languages
Creators: name: Burck, Charlotte
Publisher: name: The Open University
Year: 2003

description: This thesis is a qualitative research study exploring questions of how individuals construct living life in several languages, and of relational issues that arise. It pays attention to subjectivity and its interconnection with language. The study brings together perspectives from linguistics, translation literature, cultural theory, discursive psychology and systemic psychotherapy to consider issues of bilingualism / multilingualism at individual, family and societal levels, and to challenge the ongoing negativity associated with it. Five autobiographies and twenty-four research interviews with individuals who live in several languages form the research data. These insider accounts are treated as both referential and performative, and analysed using a synthesised grounded analysis and discursive analytic approach. It was found that individuals experience themselves differently in each language and construct their languages differently. The study identifies the discursive work individuals carry out in relation to these dissimilarities, such as the way they draw on a construct of a doubled identity, and conceptualise entry into a new language as performance. Individuals use their languages to make salient their own and others' identities. In Britain, speaking a minoritised language acts as a marker of difference and intersects with racialisation, helping to construct ethnicity and cultural identity. Although challenging, individuals develop strategies of hybridisation in enabling contexts, using the interaction between their different languages to create new perspectives, and see their multiplicity as advantage. Issues for families speaking several languages are discussed. Parents found first languages lent intimacy to parenting relationships; second languages conferred distance which helped avoid unhelpful interactions. The concept of 'mother tongue' is constitutive, perceived as language for mothers, and contributes to fathers using their first languages less. The thesis argues how crucial it is for psychotherapists to explore the differential effects of language on subjectivity and relationships, neglected to date, and for the importance of supporting bi/multilingualism.

description: It is shown that a general radial conformal Killing vector in Minkowski space-time can be associated to a generator of time evolution in conformal quantum mechanics. Among these conformal Killing vectors one finds a class which maps causal diamonds in Minkowski space-time into themselves. The flow of such Killing vectors describes worldlines of accelerated observers with a finite lifetime within the causal diamond. Time evolution of static diamond observers is equivalent to time evolution in conformal quantum mechanics governed by a hyperbolic Hamiltonian and covering only a segment of the time axis. This indicates that the Unruh temperature perceived by static diamond observers in the vacuum state of inertial observers in Minkowski space can be obtained from the behaviour of the two-point functions of conformal quantum mechanics.

description: A search for pair-produced charged Higgs bosons was performed in the data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 209 GeV. Five different final states, tau+ nu_tau tau- anti-nu_tau, c sbar cbar s, c sbar tau- anti-nu_tau, W* A W* A and W* A tau- anti-nu_tau were considered, accounting for the major expected decays in type I and type II Two Higgs Doublet Models. No significant excess of data compared to the expected Standard Model processes was observed. The existence of a charged Higgs boson with mass lower than 76.7 GeV/c^2 (type I) or 74.4 GeV/c^2 (type II) is excluded at the 95% confidence level, for a wide range of the model parameters. Model independent cross-section limits have also been calculated.

description: The effective delivery of public agricultural goods and services is fundamental to boosting the performance of agriculture in many developing countries, including Nigeria. Making public spending more efficient in providing public goods and services, such as agricultural research and extension, is critical for increasing productivity growth and farmer incomes (World Bank 2007a). While fiscal decentralization in Nigeria offered new opportunities for the provision of public goods and services, it also created challenges for the achievement of public spending efficiency due to inadequate capacity and accountability at the subnational level (Khemani 2006; World Bank 2007a). A review of public expenditures in Nigeria finds evidence for both technical and allocative inefficiency in public spending, particularly at the subnational level (Olomola et al. 2014). Low budget implementation or large differences between budgets and final expenditures, as well as large deviations between capital and recurrent spending, at the subnational level underscore the importance of understanding the drivers of public expenditure allocations in agriculture. This type of understanding will help to identify how best to support effective public expenditures in agriculture and to promote efficiency in the allocation of resources.

description: Mössbauer nuclei feature exceptionally narrow resonances at hard x-ray energies, which render them ideal probes for structure and dynamics in condensed-matter systems, and a promising platform for x-ray quantum optics and fundamental tests. However, a direct spectroscopy at modern x-ray sources such as synchrotrons or x-ray free electron lasers is challenging, because of the broad spectral bandwidth of the delivered x-ray pulses, and because of a limited spectral resolution offered by x-ray optics and detectors. To overcome these challenges, here, we propose a spectroscopy technique based on a spectrally narrow reference absorber that is rapidly oscillating along the propagation direction of the x-ray light. The motion induces sidebands to the response of the absorber, which we scan across the spectrum of the unknown target to gain spectral information. The oscillation further introduces a dependence of the detected light on the motional phase at the time of x-ray excitation as an additional controllable degree of freedom. We show how a Fourier analysis with respect to this phase enables one to selectively extract parts of the recorded intensity after the actual experiment, throughout the data analysis. This allows one to improve the spectral recovery by removing unwanted signal contributions. Our method is capable of gaining spectral information from the entire measured intensity, and not only from the intensity at late times after the excitation, such that a significantly higher part of the signal photons can be used. Furthermore, it not only enables one to measure the amplitude of the spectral response, but also its phase.

description: Despite substantial past investment and continued interest in irrigation dam construction in Nigeria, evidence on the impact of such dams on household welfare is generally scarce. In particular, relatively few studies have been done on the geographical scope that their benefits may reach, despite growing evidence from elsewhere that the benefits of large irrigation dams can extend beyond the districts or hydrological basins that contain them, reaching particularly to hydrological basins located downstream. This study assesses the short-term effects of large irrigation dams on household consumption in the northern part of Nigeria. Using two rounds of the Nigeria LSMS survey, we apply multinomial logit inverse probability weighting (MIPW) methods to construct matching samples across three different types of hydrological basins – dam basins, which are basins that contain large irrigation dams and the area upstream of such dams; downstream basins, which are located downstream of large irrigation dams; and non-dam basins, which are not associated with large irrigation dams. Our analyses particularly focus on the benefits provided by such dams for mitigating the drought risks faced by farm households. Drought is an important factor that affects adversely the welfare of farm household in Nigeria. Supplemental irrigation is often used during drought to provide water to crops.

description: The scale of quantum mechanical effects in matter is set by Planck's constant, $\hbar$. This represents the quantisation scale for material objects. In this article, we present a simple argument why the quantisation scale for space, and hence for gravity, may not be equal to $\hbar$. Indeed, assuming a single quantisation scale for both matter and geometry leads to the `worst prediction in physics', namely, the huge difference between the observed and predicted vacuum energies. Conversely, assuming a different quantum of action for geometry, $β\ll \hbar$, allows us to recover the observed density of the Universe. Thus, by measuring its present-day expansion, we may in principle determine, empirically, the scale at which the geometric degrees of freedom should be quantised.

title: Role of nitric oxide in the regulation of tumor necrosis factor-alpha signalling
Creators: name: Barsacchi, Rico
Publisher: name: The Open University
Year: 2003

description: Tumour Necrosis Factor-α (TNF-α) triggers cell death via apoptosis through a well defined signaling pathway activated by its p55 kDa receptor. The problem of the modulation of this signaling by intracellular second messenger is, on the contrary, a very debated and open field. In a previous paper (De Nadai et ai, 2000) we have shown that the lipidic messenger ceramide is able to increase recruitment of the TRADD protein to the p55 kDa receptor, caspase-8 activation and thus apoptosis. In the same paper we have shown that nitric oxide was able to inhibit these same features but the mechanisms through which nitric oxide and ceramide interact, however, are unclear. I have studied the contribution of ceramide-generating enzymes, i.e. the acidic and neutral sphingomyelinases (A- and N-SMase), to the apoptotic response to TNF-α, as well as their cross-talk with NO in two different cellular systems, the pro-monocytic cell line V937 and HeLa cells stably trasfected with bovine eNOS cDNA under the control of a tetracycline repressed promoter (HeLa-eNOS tet-off cell line). In U937 cells, TNF-a rapidly triggered both A- and N-SMase activity. Cells pre-incubation with the NO donor SNAP inhibited activation of both enzymes. These effects of the NO donor were mimicked by 8-Br cyclic GMP, and reverted by the guanylate cyclase inhibitor ODQ. A-SMase inhibitors reduced TNF-α triggered caspase-8 activation, while inhibition of N-SMase resulted in no effect. In HeLa cells eNOS expression was found to exert a protective effect on TNF-α induced apoptosis and, moreover, TNF-α was found to activate eNOS through a N-SMase/Pi3K/Akt dependent signalling pathway. These results suggest the existence of a regulatory loop in which NO and ceramide acts in concert in order to modulate TNF-α signalling.

description: The North Carolina Grape industry has undergone dramatic changes in the past two decades. Production and acreage expanded rapidly in the late 1960s and early 1970s in reaction to favorable prices from a boom in the wine market. However, producers experienced severe adjustment problems in the late 1970s and early 1980s as the wine boom turned to a bust and as grape prices plummeted. In recent years, both production and real (inflation-adjusted) prices have been low by historical S·tandards. Questions; facing the industry are: What are the future prospects for North Carolina grape producers? Have, current adjustment problems been worked out? Does a potential exist for future expansion of the industry? The intent of the present study is to isolate and to quantify economic factors affecting the equilibrium size of the North Carolina grape industry in order to provide a basis for assessing future prospects for North Carolina producers. The specific objectives are: a. to determine and quantify the factors affecting demand for North Carolina. grapes; b. to develop conditional forecasts of future demand fat North Carolina. grapes, given estimates of. break-even prices for grapes and projections of income and prices for substitute grapes. The report is organized as follows. The next section presents background information on the· industry and patterns of change_in prices and qμantities. In the third section, factors affecting demand for North Carolina grapes are identified and quantified. The fourth section utilizes the demand estimates together with projections on income and prices for substitute grapes to develop conditional projections of the size of the North Carolina grape industry for different break-even prices for North Carolina grapes. Finally, conclusions are presented in the last section.

The sector employs approximately 49 percent of Nigeria’s total workforce and contributes about 20 percent of Nigeria’s gross domestic product (United Nations 2016). Moreover, a significant accumulation of evidence demonstrates that public spending in agriculture is one of the most direct and effective ways of promoting agricultural growth, generating income, and reducing poverty (see Fan 2008; Mogues and Benin 2012). Evidence is also mounting on the potential for public agricultural spending to significantly improve nutrition and health outcomes (see Mogues, Fan, and Benin 2015). However, public agricultural spending in Nigeria remains low by several measures. Between 2003 and 2014, only 3 percent of Nigeria’s total budget, on average, was spent on agriculture (ReSAKSS 2016). This level of spending falls short of the Comprehensive Africa Agriculture Development Programme target of 10 percent—a prominent commitment of the Maputo and Malabo Declarations1. A more appropriate measure is the sufficiency of public agricultural spending relative to the sector’s contribution to the economy—also known as the intensity of public spending (Mogues et al. 2012). During the same period, the intensity of public spending on agriculture in Nigeria averaged 1.9 percent—a level too low to sustain the nation’s investment needs in agriculture.

description: Autonomous navigation of a mobile robot is a challenging task which requires ability of mapping, localization, path planning and path following. Conventional mapping methods build a dense metric map like an occupancy grid, which is affected by odometry error accumulation and consumes a lot of memory and computations in large environments. Another approach to mapping is the usage of topological properties, e.g. adjacency of locations in the environment. Topological maps are less prone to odometry error accumulation and high resources consumption, and also enable fast path planning because of the graph sparsity. Based on this idea, we proposed NavTopo - a full navigation pipeline based on topological map and two-level path planning. The pipeline localizes in the graph by matching neural network descriptors and 2D projections of the input point clouds, which significantly reduces memory consumption compared to metric and topological point cloud-based approaches. We test our approach in a large indoor photo-relaistic simulated environment and compare it to a metric map-based approach based on popular metric mapping method RTAB-MAP. The experimental results show that our topological approach significantly outperforms the metric one in terms of performance, keeping proper navigational efficiency.

description: Using recent results on higher order cumulants of conserved charge fluctuations from lattice QCD, we construct mean, variance, skewness, kurtosis, hyper-skewness and hyper-kurtosis of net-baryon number distributions for small baryon chemical potentials $μ_B$. For the strangeness neutral case ($μ_S=0$) at fixed ratio of electric charge to baryon number density ($\frac{n_Q}{n_B}=0.4$), which is appropriate for a comparison with heavy ion collisions, we present results for $κ_B σ_B^2$, $S_B σ_B^3/M_B$, $κ^{H}_{B}σ_{B}^4$ and $S^{H}_{B}σ^5_{B}/M_{B}$ on the crossover line for the chiral transition, $T_{pc}(μ_B)$. Continuum extrapolations for this pseudo-critical transition line have recently been reported by HotQCD up to baryon chemical potentials $μ_B\simeq 300$ MeV [arXiv:1812.08235]. These cumulant ratios are of direct relevance for comparisons with corresponding ratios measured by STAR in the BES-I and II runs at beam energies $\sqrt{s_{NN}}\ge 20$ GeV. In particular, we point out that recent high statistics results on skewness and kurtosis of net-baryon number distributions obtained by STAR at $\sqrt{s_{NN}} = 54.4$ GeV put strong constraints on freeze-out parameters and are consistent with predictions from thermal QCD.

description: Die Masterarbeit geht der Frage nach: Wie wird natürliche Differenzierung im Mathematikunterricht von drei Lehrpersonen von zweiten Primarklassen im Kanton St. Gallen verstanden und umgesetzt? Im Vordergrund stehen das aktiv-entdeckende Lehren und Lernen nach Wittmann, die beziehungshaltige Mathematik nach Freudenthal und der Umgang mit Heterogenität nach Krauthausen und Scherer. Die qualitative Inhaltsanalyse der Leitfadeninterviews zeigt, dass ein unterschiedliches Begriffsverständnis verbunden mit nicht konsistenten Umsetzungen vorherrscht, was als Risikofaktor zu verstehen ist. Dass eine Lehrperson durch die Umsetzung einer natürlichen Differenzierung im Unterricht möglichst vielen Lernenden gerecht werden kann und sozialer Austausch stattfindet, wird als Chance für die gesamte Unterrichtsqualität erkannt. Zentraler Gelingens-Faktor einer natürlichen Differenzierung ist die Grundhaltung einer Lehrperson.

description: We investigate the $E_g \otimes e_g$ Jahn-Teller system for the purpose to reveal the nature of quantum chaos in crystals. This system simulates the interaction between the nuclear vibrational modes and the electronic motion in non-Kramers doublets for multiplets of transition-metal ions. Inclusion of the anharmonic potential due to the trigonal symmetry in crystals makes the system nonintegrable and chaotic. Besides the quantal analysis of the transition from Poisson to Wigner level statistics with increasing the strength of anharmonicity, we study the effect of chaos on the electronic orbital angular momentum and explore the magnetic $g$-factor as a function of the system's energy. The regular oscillation of this factor changes to a rapidly-decaying irregular oscillation by increasing the anharmonicity (chaoticity).

description: Spiking Neural Network (SNN) is the third generation of Neural Network (NN) mimicking the natural behavior of the brain. By processing based on binary input/output, SNNs offer lower complexity, higher density and lower power consumption. This work presents an efficient software-hardware design framework for developing SNN systems in hardware. In addition, a design of low-cost neurosynaptic core is presented based on packet-switching communication approach. The evaluation results show that the ANN to SNN conversion method with the size 784:1200:1200:10 performs 99% accuracy for MNIST while the unsupervised STDP archives 89% with the size 784:400 with recurrent connections. The design of 256-neurons and 65k synapses is also implemented in ASIC 45nm technology with an area cost of 0.205 $m m^2$.

description: We analyze experimental data of nuclear structure-function ratios F_2^A/F_2^{A'} and Drell-Yan cross section ratios for obtaining optimum parton distribution functions (PDFs) in nuclei. Then, uncertainties of the nuclear PDFs are estimated by the Hessian method. Valence-quark distributions are determined by the F_2 data at large x; however, the small-x part is not obvious from the data. On the other hand, the antiquark distributions are determined well at x~0.01 from the F_2 data and at x~0.1 by the Drell-Yan data; however, the large-x behavior is not clear. Gluon distributions cannot be fixed by the present data and they have large uncertainties in the whole x region. Parametrization results are shown in comparison with the data. We provide a useful code for calculating nuclear PDFs at given x and Q^2.
