description: The study examines the input-output relationship and resource use efficiency in milk production in Churu district of Rajasthan, a dry area. The results indicate a sub-optimal use of resources for milk production both from local cows as well as buffaloes. Milk production may be enhanced by increased use of concentrates and green fodder. Since production of green fodder in the area is contingent on rains. emphasis should be placed on the increased use of concentrates.

description: An optimal control law for networked control systems with a discrete-time linear time-invariant (LTI) system as plant and networks between sensor and controller as well as between controller and actuator is proposed. This controller is designed by solving an optimization problem that is a generalization of the optimization problem used to obtain the Linear Quadratic Regulator (LQR) for deterministic discrete-time LTI systems. The networks are represented by random delays and drop outs of transmitted data packets.

description: One of the main science motivations for the ESA PLAnetary Transit and Oscillations (PLATO) mission is to measure exoplanet transit radii with 3% precision. In addition to flares and starspots, stellar oscillations and granulation will enforce fundamental noise floors for transiting exoplanet radius measurements. We simulate light curves of Earth-sized exoplanets transiting continuum intensity images of the Sun taken by the HMI instrument aboard SDO to investigate the uncertainties introduced on the exoplanet radius measurements by stellar granulation and oscillations. After modeling the solar variability with a Gaussian process, we find that the amplitude of solar oscillations and granulation is of order 100 ppm -- similar to the depth of an Earth transit -- and introduces a fractional uncertainty on the depth of transit of 0.73% assuming four transits are observed over the mission duration. However, when we translate the depth measurement into a radius measurement of the planet, we find a much larger radius uncertainty of 3.6%. This is due to a degeneracy between the transit radius ratio, the limb-darkening, and the impact parameter caused by the inability to constrain the transit impact parameter in the presence of stellar variability. We find that surface brightness inhomogeneity due to photospheric granulation contributes a lower limit of only 2 ppm to the photometry in-transit. The radius uncertainty due to granulation and oscillations, combined with the degeneracy with the transit impact parameter, accounts for a significant fraction of the error budget of the PLATO mission, before detector or observational noise is introduced to the light curve. If it is possible to constrain the impact parameter or to obtain follow-up observations at longer wavelengths where limb-darkening is less significant, this may enable higher precision radius measurements.

description: The concept of Lorentz scalar quark confinement has a long history and is still widely used despite its well-known theoretical faults. We point out here that the predictions of scalar confinement also conflict directly with experiment. We investigate the dependence of heavy-light meson mass differences on the mass of the light quark. In particular, we examine the strange and non-strange D mesons. We find that the predictions of scalar confinement are in considerable conflict with measured values.

description: One of the major demographic trends in the US is the aging of farm operators and landlords suggesting transition of farm ownership in the form of exit and disinvestment. This coincides with economic pressures on farmers’ incomes due to recent market volatility. We model retirement age farmers’ exit/disinvestment as the outcome of intertemporal utility maximization and identify the extent to which economic and demographic factors affect these choices using the Census of Agriculture farm-level data for the 1992-2012 period. Regression results highlight the role of demographic factors. Minority and female farmers are more likely to exit but female operators are less likely to disinvest, while family farms are less likely to exit. High sales farms are less likely to exit but more likely to disinvest possibly targeting a smaller production scale before retirement. The relative size of the non-agricultural economy is negatively associated with exit but positively with disinvestment, while off-farm work reduces exit probability only a little. However, flow economic variables such as return-on-assets and government payments do not seem to impact exit and disinvestment. These findings are largely consistent with the view that mainly demographic factors and size determine farmers’ decisions to retire, which has important policy implications.
title: Thermal Evolution of the Mid-Crust From the Himalayan Orogen
Creators: name: Chambers, Jennifer Ann
Publisher: name: The Open University
Year: 2008

description: The Haimanta Group, at the top of the exhumed mid-crust in the western Himalaya (Sutlej valley), underwent prograde metamorphism to depths of 25 to 30 km at c. 30 Ma. Initial exhumation of the Haimanta Group was accompanied by further heating, from 610-620 °C up to 660 °C at c. 23 Ma; further exhumation (at c. 1.3 mm/yr) to a depth of c. 7 km during the Early Miocene resulted in cooling to 300-350 °C. Meanwhile, the underlying Greater Himalayan Sequence (GHS) was rapidly exhumed due to coeval extension on the South Tibetan Detachment above and compression on the Main Central Thrust below. The Jutogh Group, with Palaeoproterozoic (c. 1810 Ma) leucogranites characteristic of the Lesser Himalayan Sequence, was buried and metamorphosed beneath the overthrust GHS, and involved the partial recrystallisation of uraninite in leucogranite at 11 Ma. The Chekha Formation (Radi klippe) in the eastern Himalaya (Bhutan), in a similar structural position to the Haimanta Group, also reveals a history of Oligocene prograde metamorphism, to c. 7 kbars and 550-620°C at c. 22 Ma, synchronous with prograde metamorphism in the underlying GHS (peak metamorphism, c. 24 Ma). Comparable metamorphism and deformation in the Haimanta Group and Chekha Formation, distinct from that in the underlying GHS, is the result of a common tectono-thermal process in the early evolution of the orogen. Pressure-temperature-time data from the metamorphic core are generally consistent with the channel flow model, but may be equally compatible with contesting models. Uranium(-thorium)-lead isotope analysis of monazite (which formed above 580 °C after, or during the final stages of garnet growth, and probably via the breakdown of allanite and apatite) provided a robust method for dating prograde-peak metamorphism. Samarium-neodymium garnet geochronology was hampered by Ca-bearing Nd-rich garnet inclusions (e.g. allanite).

description: Holographic duality implies that the geometric properties of the gravitational bulk theory should be encoded in the dual field theory. These naturally include the metric on dimensions that become compact near the conformal boundary, as is the case for any asymptotically locally $\text{AdS}_n\times\mathbb{S}^k$ spacetime. Almost all previous work on metric reconstruction ignores these dimensions and would thus at most apply to dimensionally-reduced metrics. In this work, we generalize the approach to bulk reconstruction using light-cone cuts and propose a prescription to obtain the full higher-dimensional metric of generic spacetimes up to an overall conformal factor. We first extend the definition of light-cone cuts to include information about the asymptotic compact dimensions, and show that the full conformal metric can be recovered from these extended cuts. We then give a prescription for obtaining these extended cuts from the dual field theory. The location of the usual cuts can still be obtained from bulk-point singularities of correlators, and the new information in the extended cut can be extracted by using appropriate combinations of operators dual to Kaluza-Klein modes of the higher-dimensional bulk fields.

description: This study sought to understand the disparities between non-core/micropolitan communities and metropolitan communities on life expectancy. The study also assessed the impact of individual behavioral choices and certain social variables and state and county level policies that affect the life expectancy in a county. A descriptive comparison analysis was employed to establish the differences in life expectancy across the various levels of the urban hierarchy in 1559 counties in the United States. An ordinary least squares model was used to tease out the relationship between specific individual choice factors -- smoking habits, obesity and exercise habits -- and several socio-economic variables on life expectancy. This study also estimated the effects of each correlate at the various levels of the urban hierarchy. The study concluded that the effects of both individual choice factors differed greatly across the various levels of rurality but less differences existed between the functional relationships of socioeconomic characteristics and life expectancy across the urban hierarchy.

description: Following the 2008 food crisis, West African governments have sought to achieve food security. Regional market integration is one element of this food security policy thrust. The Economic Community of West African countries (ECOWAS) is engaged in the creation of a Customs Union. Member countries negotiated a common external tariff (CET) currently under implementation. The CET is organized into five different tariff bands of 0, 5, 10, 20, and 35 percent to accommodate the large variations in protection granted across the region. The implementation of the CET represents a challenge to many individual ECOWAS countries since it may generate significant and potentially destabilizing welfare distribution impacts. The objective of this study is to evaluate the impact of ECOWAS CET on the rice sectors and the food security situation of member countries, and the spillover effects on the international market. Rice has become a dominant food staple and consequently West Africa has become the largest global rice-importing region, therefore it is important to understand likely impacts of regional integration on this sector. We use a supply-chain, partial, spatial equilibrium model of the global rice economy calibrated to the prevailing market conditions for the period 2013-2015. The findings highlight the impact of the CET on rice production, consumption, bilateral trade, and consumer, producer, and government welfare at the regional and global level, and the potential policy implications of such changes.

Continuity from neutron matter to color-superconducting quark matter with $^3 P_2$ superfluidity

description: I clarify how the concept of quark-hadron continuity, which was previously considered in the context of the asymptotic color-flavor locked phase with ideal three-flavor symmetry, is applied to two-flavor matter. Our observation is that neutron star matter can continuously be connected to two-flavor color-superconducting (2SC) phase with an additional condensate of $d$-quarks in the $^3P_2$ channel. I discuss here two aspects of this novel phase. First, I introduce the notion of continuity based on the patterns of symmetry breaking and the corresponding order parameters, and then explain qualitatively the physics mechanism of $d$-quark $^3P_2$ pairing in analogy to nuclear physics. Our finding serves as the theoretical underpinning for the phenomenological construction of the equation of state in the neutron star environment.

title: Mechanisms Controlling the Unique Phenotype of Brain Endothelium
Creators: name: Sade, Hadassah S.
Publisher: name: The Open University
Year: 2009

description: Endothelial cells from different tissues differ widely in the expression of junctional proteins like occludin and transporters like the transferrin receptor. The mechanism(s) responsible for the differential expression of these proteins is not known. In this project we have studied how the occludin promoter interacts with nuclear transcription factors (TFs) from brain and non-brain endothelium. EMSA data indicates the TFs Sp1, Sp3 and YY1 are responsible for the specific binding to the occludin promoter in hCMEC/D3 cells, a transformed brain endothelial cell line. Using ChIP assays, we confirmed the interaction between these three transcription factors and DNA as these complexes were active in live cultured cells from transformed and primary brain endothelium. We investigated the expression and localisation of Sp1, Sp3 and YY1 in these cells and compared with lung endothelial cells and report the specific association of the TFs Sp3 and YY1 in brain endothelium which is absent in non brain endothelium. In addition, we have compared the activity of the occludin promoter in hCMEC/D3 cell to that in primary human dermal and lung endothelial cells by transfection with reporter vectors under the control of the full length and fragments of the occludin promoter. Our work identifies a group of transcription factors present in brain endothelium which may regulate the expression of the tight junction protein occludin. We propose a model whereby the TF Sp3 is necessary for the transcription of the occludin promoter in brain endothelium and YY1 negatively regulates promoter activity in non-brain endothelium by controlling access of Sp3 to the initiation sites on the occludin promoter.

We also characterize the zero-noise limit measures for a model of the intermittent map and obtain stochastic stability for some values of the parameter. The physical measures are obtained as zero-noise limits which are shown to satisfy Pesin?s Entropy Formula.

description: We introduce the Nuclear Electronic All-Particle Density Matrix Renormalization Group (NEAP-DMRG) method for solving the time-independent Schrödinger equation simultaneously for electrons and other quantum species. In contrast to already existing multicomponent approaches, in this work we construct from the outset a multi-reference trial wave function with stochastically optimized non-orthogonal Gaussian orbitals. By iterative refining of the Gaussians' positions and widths, we obtain a compact multi-reference expansion for the multicomponent wave function. We extend the DMRG algorithm to multicomponent wave functions to take into account inter- and intra-species correlation effects. The efficient parametrization of the total wave function as a matrix product state allows NEAP-DMRG to accurately approximate full configuration interaction energies of molecular systems with more than three nuclei and twelve particles in total, which is currently a major challenge for other multicomponent approaches. We present NEAP-DMRG results for two few-body systems, i.e., H$_2$ and H$_3^+$, and one larger system, namely BH$_3$

description: The characteristic function of soliton phase jitter is found analytically when the soliton is perturbed by amplifier noise. In additional to that from amplitude jitter, the nonlinear phase noise due to frequency and timing jitter is also analyzed. Because the nonlinear phase noise is not Gaussian distributed, the overall phase jitter is also non-Gaussian. For a fixed mean nonlinear phase shift, the contribution of nonlinear phase noise from frequency and timing jitter decreases with distance and signal-to-noise ratio.

description: The budding yeast {\it Saccharomyces cerevisiae} is the first eukaryote whose genome has been completely sequenced. It is also the first eukaryotic cell whose proteome (the set of all proteins) and interactome (the network of all mutual interactions between proteins) has been analyzed. In this paper we study the structure of the yeast protein complex network in which weighted edges between complexes represent the number of shared proteins. It is found that the network of protein complexes is a small world network with scale free behavior for many of its distributions. However we find that there are no strong correlations between the weights and degrees of neighboring complexes. To reveal non-random features of the network we also compare it with a null model in which the complexes randomly select their proteins. Finally we propose a simple evolutionary model based on duplication and divergence of proteins.

description: For many years ‘big data’ has been considered by many as the privilege of the few. Because of its volume, it could only be handled by large corporations, essentially based in the west; because of its complexity, it required high level specialists to manage it, and because of the cost of putting it together, it rested out of reach of the common person’s purse. This has changed. During this lifetime, the world has gone through three consecutive and very fundamental revolutions. The first was the Internet connecting the world together. The second was the emergence of intelligent devices, starting with mobile phones, bringing knowledge to your fingertips. The third revolution is here: open data. Knowledge can now flow across the world with accuracy, at a speed and volume never reached before. The world of agriculture is one of the key beneficiaries of this latest revolution, seeing for the first time the innovative benefits of a true ‘cooperative development process’ taking place. Governments are opening their data; research is working hand in hand with the private sector; and civil society – consumers and farmers alike – is voicing its needs and triggering innovation tailored to its capacity, situation and choices. As a result, even in the most remote areas today you can see applications using the latest technology – and ‘big data’ – in the hands of farmers and in a form and shape that makes sense for them. Applications are affordable and manageable, allowing their users to gradually overcome subsistence farming to reach a higher quality of life. Globally this means that continents where agriculture is still the key development engine see their economy improving, hunger decreasing and innovation flourishing. This is what will lead the world to overcome the emerging food security challenges ahead of us, and contribute greatly to allow developing countries to reach their full potential. This presentation describes this process and gives concrete examples of where and how ‘big data’ is now used by small farmers; and more generally, how open data is changing the face of global agriculture.

description: Lanthanide elements play important roles as an opacity source in the ejected material from neutron star mergers. Accurate and complete atomic data are necessary to evaluate the opacities and to analyze the observed data. In this paper, we perform extended, ab-initio atomic calculations from Pr II (Z=59) to Gd II (Z=64). By using multiconfiguration Dirac-Hartree-Fock and relativistic configuration-interaction methods, implemented in the general-purpose relativistic atomic structure package GRASP2K, we calculate the energy levels and transition data of electric dipole transitions. These computations are based on strategies (with small variations) of Nd II published by Gaigalas et al. (2019). Accuracy of data is evaluated by comparing computed energy levels with the NIST database or other works. For the energy levels, we obtain the average relative accuracy of 8%, 12%, 6%, 8%, and 7% for Pr II, Pm II, Sm II, Eu II, and Gd II ions, respectively as compared with the NIST data. Accuracy of energy transfer to the wavelength as 3%, 14% and 11% for Pr II, Eu II and Gd II. Our computed E1 type transition probabilities are in good agreement with experimental values presented by other authors especially for strong transitions.

description: An alternative to dark energy as an explanation for the present phase of accelerated expansion of the Universe is that the Friedmann equation is modified, e.g. by extra dimensional gravity, on large scales. We explore a natural parametrization of a general modified Friedmann equation, and find that the present supernova type Ia and cosmic microwave background data prefer a correction of the form 1/H over a cosmological constant. We also explore the constraints that can be expected in the future, and find that there are good prospects for distinguishing this model from the standard cosmological constant to very high significance if one combines supernova data with a precise measurement of the matter density.

Towards a multiplex network model of word associations and similarity in the human mind

description: Early language acquisition is a cognitive process mediating the learning of words according to heterogenous linguistic knowledge, e.g. semantics and phonology. Even if cognitive networks are insightful for understanding how conceptual associations influence word acquisition, current approaches do not account for the interplay between structure and word features, i.e. exploitable node metadata. In this work, we aim to investigate word learning by merging relational structure and word features, like frequency, length and polysemy, in a multilayer representation enhanced with vector spaces.

description: The 2005 ICDP-USGS deep drilling of the Chesapeake Bay Impact Structure (CBIS) returned the first complete core through an impact structure. A strict set of contamination assessment measures were implemented during sample collection to ensure that materials could be confidently used in geobiology, molecular biology and microbiology studies. Through direct cell counting, culturing and molecular analysis, samples offered a unique opportunity to characterize the subsurface microbial community present at depth in an impact structure. This work outlines how subsurface habitats can recover after impacts, and how impacts act to generate new microenvironments where microorganisms can colonize. Geobiology studies revealed a pattern of microbial abundance that corresponds to lithological transitions within the crater structure. Three 'zones' of abundance were defined, with the first showing a steeper logarithmic decline in cell numbers than seen in other deep subsurface environments. This is followed by a zone of cell numbers below the detection limit of the methods used. Finally, the deepest section of the core shows an increase in cell numbers, indicating that recolonisation has occurred following the impact event. Culturing studies were consistent with the results of enumerations, with successful cultures retrieved from microbiological zones 1 and 3. The majority of cultures were acquired using heterotrophic media, although cultures were also returned with media for iron reducers, iron oxidizers, sulfate reducers and humic acid utilisers. Culturing studies and molecular studies showed that a diverse consortium of microorganisms is present in the deep subsurface of the CBIS. Finally, the ability of microorganisms to access nutrients and minerals from meteoritic material was analyzed. The results of these studies add to our knowledge of how impacts events can affect subsurface microbial habitats; both directly by kinetic disruption of the environment, and through the delivery of exogenous materials.

description: ‘Big data’ has great unrealised potential in most parts of the agricultural value-chain. We can divide that data up into several categories, each with its own good and bad points. Starting in 1972, the US Landsat program collected the original ‘big data’, but capability to perform meaningful analysis of the photos remained very expensive until recently. Other flows have begun in the past few decades, from private satellites, point-of-sale systems, land-based sensors, and aerial drones. Unlike Landsat, the various newer sources have different ownership statuses. Globally, most smallholders don’t generate the revenue to pay for any of the various proprietary data sources or analysis. But we see significant value in the application of machine learning/’big data’ techniques to publicly available satellite and other sources. Advances in information technology allow us to disseminate good-quality yield, drought, and other analyses at a much lower cost than previously. As a result, relatively small external contributions can bring the established benefits of modern modelling expertise to a hugely broader and more diverse audience.

description: A phenomenological study of the isolated photon production in high energy $pp$ and $pA$ collisions at RHIC and LHC energies is performed. Using the color dipole approach we investigate the production cross section differential in the transverse momentum of the photon considering three different phenomenological models for the universal dipole cross section. We also present the predictions for the rapidity dependence of the ratio of $pA$ to $pp$ cross sections. As a further test of the formalism, for different energies and photon rapidites we analyse the correlation function in azimuthal angle $Δϕ$ between the photon and a forward pion. The characteristic double-peak structure of the correlation function around $Δϕ\simeq π$ observed previously for Drell-Yan pair production is found for isolated photon emitted into the forward rapidity region which can be tested by future experiments.

description: Information about the global structure of agriculture and nutrient production and its diversity is essential to improve understanding of food production patterns, agricultural livelihoods, and food chains and their linkages to land use and their associated ecosystems services. We used existing spatially-explicit global datasets to estimate the production levels of crops, livestock, and aquaculture and fish products. We also estimated the production of vitamin A, vitamin B12, folate, iron, zinc, calcium, calories and protein. Furthermore, we estimated the relative contribution of farms of different sizes to the production of different agricultural commodities and associated nutrients, as well as how the diversity of food production, based on the number of different products grown per geographic pixel and distribution of products within this pixel (Shannon diversity index [H]), changes with different farm sizes. Globally, small and medium farms (≤50 ha) produce 51–77% of nearly all commodities and nutrients examined here. However, important regional differences exist. Large farms (>50 ha) dominate production in North America, South America, and Australia and New Zealand. By contrast, small farms (≤20 ha) produce more than 75% of most food commodities in sub-Saharan Africa, south-east Asia, south Asia and China. The majority of vegetables (81%), roots and tubers (72%), pulses (67%), fruits (66%), fish and livestock products (60%) and cereals (56%) are produced in diverse landscapes (H>1·5). Our results show that farm size and diversity of agricultural production vary substantially across regions and are key structural determinants of food and nutrient production that need to be considered in plans to meet social, economic and environmental targets. At the global level, both small and large farms have key roles in food and nutrition security. This analysis is crucial to design interventions that might be appropriately targeted to promote healthy diets and ecosystems in the face of population growth, urbanisation and climate change.

description: The photon -- induced interactions, present in $ep$, $eA$, $pp$, $pA$, $AA$ and $e^+ e^-$ collisions, are expressed within the color dipole approach in terms of the photon wave function, which describes the transition of the photon into a quark -- antiquark color dipole. Such quantity is usually calculated using perturbation theory assuming that long distance corrections associated to strong interactions can be neglected. In this paper we investigate the impact of these nonperturbative QCD (npQCD) corrections to the description of the photon wave function for dipoles of large size in several observables measured at HERA, LEP and LHC. We assume a phenomenological ansatz for the treatment of these npQCD corrections and constrain the free parameters of our model using the experimental data for the photoproduction cross section. The predictions for the $γγ$ cross section, exclusive $ρ$ production in $ep$ collisions and the rapidity distribution for the $ρ$ production in $PbPb$ collisions are compared with the data. We demonstrate that the inclusion of the nonperturbative QCD corrections improves the description of processes that are dominated by large dipoles.
