description: We present a calculation of the effective cross section $σ_{eff}$, an important ingredient in the description of double parton scattering in proton-proton collisions. Our theoretical approach makes use of a Light-Front quark model as framework to calculate the double parton distribution functions at low-resolution scale. QCD evolution is implemented to reach the experimental scale. The obtained $σ_{eff}$, when averaged over the longitudinal momentum fractions of the interacting partons, $x_i$, is consistent with the present experimental scenario. However the result of the complete calculation shows a dependence of $σ_{eff}$ on $x_i$, a feature not easily seen in the available data, probably because of their low accuracy. Measurements of $σ_{eff}$ in restricted $x_i$ regions are addressed to obtain indications on double parton correlations, a novel and interesting aspect of the three dimensional structure of the nucleon.

description: Anomalous perceptions are characterised by the subjective experience of a range of distorted and/or hallucinatory percepts. Whilst considerable attention has been paid to the neurocognitive processes contributing to anomalous perceptions amongst older adults, less is known about the social factors (e.g. social isolation, loneliness). Furthermore, it is unknown whether loneliness and social isolation are associated with different types of anomalous perceptions, including anomalous body-centred self-experiences and anomalous external experiences. This study examined the cross-sectional relationships between loneliness, objective social isolation, and anomalous perceptions in a sample of community-dwelling older adults (N = 242, Mage = 71.87 ± 7.73, range = 52-91, 67.8% female) using structural equation modelling. Higher levels of loneliness were associated with more anomalous body-centred self-experiences and anomalous external experiences. Those reporting more loneliness also reported higher levels of anxiety and depression; however, the relationship between loneliness and anomalous perceptions was not mediated by these factors. Social disconnection from a religious group was associated with more anomalous external experiences and being married/living with a partner was associated with more anomalous body-centred self-experiences. These findings suggest that loneliness and social isolation have differential associations with anomalous perceptions in older adults and provide additional evidence that attending to loneliness in older adults is important.

description: Nowadays, awareness of sustainable agriculture is on the rise. Biochar is usually used as soil amendment to improve soil properties. The experiment is aimed to find the better combination of fertilizer and biochar rate which get higher yield of okra (Abelmoschus esculentus L.). Biochar rate is applied at 0, 10, 20, 30 t/ha and combine with mineral fertilizer and organic fertilizer. Experiment result shows that no matter combine with mineral or organic fertilizers, okra yield get higher as the increasing biochar rate. There’s no significant difference between yield of conventional plot and organic plot when at the same biochar rate. Treatment without fertilizer and biochar (control) got the lowest yield

description: Most molecular clouds are filamentary or elongated. Among those forming low-mass stars, their long axes tend to be either parallel or perpendicular to the large-scale (10-100 pc) magnetic field (B-field) in the surrounding inter cloud medium. This arises because, along the dynamically dominant B-fields, the competition between self-gravity and turbulent pressure will shape the cloud to be elongated either perpendicular or parallel to the fields. Recent study also suggested that, on the scales of 0.1-0.01 pc, fields are dynamically important within cloud cores forming massive stars. But whether the core field morphologies are inherited from the inter cloud medium or governed by cloud turbulence is under vigorous debate, so is the role played by B-fields in cloud fragmentation at 10 - 0.1 pc scales. Here we report B-field maps covering 100-0.01 pc scales inferred from polarimetric observations of a massive-star forming region, NGC 6334. First, the main filament also lies perpendicular to the ambient field. NGC 6334 hosts young star-forming sites where fields are not severely affected by stellar feedback, and their directions do not change significantly over the entire scale range. This means that the fields are dynamically important. At various scales, we find that the hourglass-shaped field lines are pinched where the gas column density peaks and the field strength is proportional to the 0.4-power of the density. We conclude that B-fields play a crucial role in the fragmentation of NGC 6334.

description: Low pressure center pivot irrigation was the most energy efficient sprinkler irrigation system of the four sprinkler irrigation systems simulated for three representative types of Nebraska farms. Given 1978 and 1980 energy prices, natural gas was the least expensive fuel for powering the systems. Although an autogated pipe irrigation system proved most efficient in simulation, it is untried and is limited to fields adaptable to surface irrigation. Increased energy costs may force some irrigators to switch to dryland farming, convert to a less energy-intensive system, or irrigate with the present system and forego replacement if salvageability is too low

description: The usually small sulphide phase in serpentinized peridotites is of interest when trying to evaluate reaction conditions during alteration, such as fO2, aH2 and aH2S, with one important indication being the occurrence of native metals and metal alloys. Using high resolution imaging and element mapping on samples from an active, continental serpentinization area in southwestern Turkey, sulphides, their composition and mineralogy, elemental distribution, and textures on a scale down to 30nm are described in this thesis. At least two stages of fluid-rock-interaction are visible in the samples. With phase relations in the Fe-Ni-O-S and Fe-Ni-Co-S systems, precipitation temperatures for the sulphides (200-300°C) and activities of H2 (>10-2) and H2S (<10-4) during later, ongoing lower-temperature (50-100°C) alteration of the grains are estimated. In the microtextures, which display a fibre-like intergrowth of awaruite and silicate in reaction zones within pentlandite, part of the process which replaces pentlandite with awaruite can be observed. Some sulphides are enriched in Cu, possibly indicating another, Cu-bearing fluid interacting with the rocks.

description: Sulfur, along with salt, coal, and limestone, is one of the basic raw materials of the chemical industry. A nation's per capita sulfur consumption is a reliable index to its chemical production and a rough index to its standard of living. Sulfur, with its many properties, has literally hundreds of uses; most is used in the manufacture of fertilizers, fibers, papers, pigments, pharmaceuticals, and explosives.Sulfur or brimstone is one of the oldest elements known to man. It was used more than 4,000 years ago in rituals of sacrifice and as a bleaching agent for cotton. The Chinese, around 500 B.C., used sulfur as an ingredient in gunpowder. Arabian alchemists are thought to have discovered sulfuric acid in the 8th Century while trying to convert sulfur to gold. Sulfur became commercially important in 1791 with the development of the Leblanc soda ash process in France (Ambrose, 1965, p. 901). The sulfuric acid industry, which began in the United States near the end of the 18th Century, now uses about 87 percent of the total production. Sulfur plays an increasingly vital role in American industry and agriculture. The 1966 sulfur shortage motivated are evaluation of West Texas geologic and economic potential for sulfur production and a re-examination of its lengthy but spasmodic sulfur history.

description: Graphene hosts a unique electron system in which electron-phonon scattering is extremely weak but electron-electron collisions are sufficiently frequent to provide local equilibrium above liquid nitrogen temperature. Under these conditions, electrons can behave as a viscous liquid and exhibit hydrodynamic phenomena similar to classical liquids. Here we report strong evidence for this transport regime. We find that doped graphene exhibits an anomalous (negative) voltage drop near current injection contacts, which is attributed to the formation of submicrometer-size whirlpools in the electron flow. The viscosity of graphene's electron liquid is found to be ~0.1 m$^2$ /s, an order of magnitude larger than that of honey, in agreement with many-body theory. Our work shows a possibility to study electron hydrodynamics using high quality graphene.
Modulation of individual neuron activity with external electric fields

description: Neurons are highly-specialized cells capable of receiving and generating electrical signals through
the controlled flow of ions across their cell membranes. This behavior is represented mathematically
as a series of coupled nonlinear differential equations, which can be efficiently solved with numerical
integrators. As such, detailed computational models of neurons are readily-achievable and allow for
in-depth investigations of neuronal dynamics that are not typically possible in in vitro or in vivo
studies.
On the maximum running time in graph bootstrap percolation

description: Graph bootstrap percolation is a simple cellular automaton introduced by Bollobás in 1968. Given a graph $H$ and a set $G \subseteq E(K_n)$ we initially "infect" all edges in $G$ and then, in consecutive steps, we infect every $e \in K_n$ that completes a new infected copy of $H$ in $K_n$. We say that $G$ percolates if eventually every edge in $K_n$ is infected. The extremal question about the size of the smallest percolating sets when $H = K_r$ was answered independently by Alon, Kalai and Frankl. Here we consider a different question raised more recently by Bollobás: what is the maximum time the process can run before it stabilizes? It is an easy observation that for $r=3$ this maximum is $\lceil \log_2 (n-1) \rceil $. However, a new phenomenon occurs for $r=4$ when, as we show, the maximum time of the process is $n-3$. For $r \geq 5$ the behaviour of the dynamics is even more complex, which we demonstrate by showing that the $K_r$-bootstrap process can run for at least $n^{2-\varepsilon_r}$ time steps for some $\varepsilon_r$ that tends to $0$ as $r \to \infty$.

description: Due to discretization effects and truncation to finite domains, many electromagnetic simulations present non-physical modifications of Maxwell's equations in space that may generate spurious signals affecting the overall accuracy of the result. Such modifications for instance occur when Perfectly Matched Layers (PMLs) are used at simulation domain boundaries to simulate open media. Another example is the use of arbitrary order Maxwell solver with domain decomposition technique that may under some condition involve stencil truncations at subdomain boundaries, resulting in small spurious errors that do eventually build up. In each case, a careful evaluation of the characteristics and magnitude of the errors resulting from these approximations, and their impact at any frequency and angle, requires detailed analytical and numerical studies. To this end, we present a general analytical approach that enables the evaluation of numerical discretization errors of fully three-dimensional arbitrary order finite-difference Maxwell solver, with arbitrary modification of the local stencil in the simulation domain. The analytical model is validated against simulations of domain decomposition technique and PMLs, when these are used with very high-order Maxwell solver, as well as in the infinite order limit of pseudo-spectral solvers. Results confirm that the new analytical approach enables exact predictions in each case. It also confirms that the domain decomposition technique can be used with very high-order Maxwell solver and a reasonably low number of guard cells with negligible effects on the whole accuracy of the simulation.

description: Reservoir quality of lower Teritary sandstone reservoirs along the Texas Gulf Coast is controlled by sandstone depositional environment, mineralogical composition, and consolidation history (compaction, cementation, and leaching). In general, shallow reservoirs have primary porosity that is reduced by compaction andcementation, whereas deeperreservoirs result from late subsurface leaching. Frio sandstones have the following idealized consolidation history: Near-surface to shallow subsurface compaction and cementation stage (0 to 4,000 feet ±) starts with early feldspar leaching and replacement by calcite followed by precipitation of poikilotopic pore-filling calcite cement, clay coats and rims, feldspar overgrowths, and initial quartz overgrowths. Sand is compacted until arrested by cementation. Reservoir porosity is reduced from 40 percent to approximately 25 percent. Moderate subsurface cementation stage (4,000 to 8,000 feet ±) consists of general precipitation of quartz overgrowths, localized welding by massive quartz overgrowths, and development of sparrypore-fill calcite cement. Porosity is commonly reduced to 10 percent. Moderate subsurface leaching stage (8,000 to 11,000 feet ±) results in massive leaching of feldspars, volcanic and carbonate rock fragments, and calcite cements. Continued leaching may resurrect porositiesto as high as 30 percent. Deep subsurface cementation stage (> 1,000feet ±)involves reduction of leached porosity by precipitation of pore-filling kaolinite and iron-rich carbonate cements; resulting porosities depend on the amount of this late cement. This rock consolidation history can be modified by residence time in each burial stage, thermal gradient, pore-fluid changes,andmineralogical differences. Deep Frio production, then, is not from simple primary porosity between grains, as in shallow reservoirs, but is from secondary leached porosity.
Characterizing pore-scale morphology of non-aqueous phase liquids using three-dimensional image analysis
Creators: name: Schaberg, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Organic immiscible fluids are common subsurface contaminants which may leach into the groundwater supply, posing a threat to human health. The development of effective remediation techniques is dependent upon a thorough understanding of the microscale processes that govern the dissolution of non-aqueous phase liquid (NAPL). In order to resolve the local mass transfer in the dissolution process from a fundamental perspective, both the pore-space and NAPL morphology must be known. The purpose of this study was to assess the morphology of trapped NAPL during dissolution using three-dimensional (3-D) image analysis. Data was taken from a previous experiment where a column was packed with a representative porous medium and trichloroethylene (TCE), and flushed with a solution containing hydroxypropyl-β-cyclodextrin (Schnaar and Brusseau 2006). 3-D images were taken of the column in its residual state and after each successive flush using X-ray microtomography. Image analysis was performed to assess the orientation, curvature, volume, and surface area of the NAPL. A comparison was constructed between the disconnected NAPL regions (DNRs) that were flushed and those that persisted. The volume, roundedness and orientation were important determinants of dissolution.

description: Coherent radiation at radio frequencies from high-energy showers fully contained in a dense radio-transparent medium - like ice, salt or regolith - has been extensively investigated as a promising technique to search for ultra-high energy (UHE) neutrinos. Additional emission in the form of transition radiation may occur when a neutrino-induced shower produced close to the Earth surface emerges from the ground into atmospheric air. We present the first detailed evaluation of transition radiation from high-energy showers crossing the boundary between two different media. We found that transition radiation is sizable over a wide solid angle and coherent up to $\sim$ 1 GHz. These properties encourage further work to evaluate the potential of a large-aperture UHE neutrino experiment based on detection of transition radiation.

description: Willow herb (Chamaenerion angustifolium (L.) Scop. syn. Epilobium angustifolium L.) from Onagraceae family is a valuable medicinal plant that has been used in the treatment of urogenital disorders including BPH (Benign Prostatic Hypertrophy). The raw material is a rich source of polyphenols as well as steroids, triterpenoids and fatty acids. The extracts show pharmacological activities: anti-androgen, anti-proliferative, anti-inflammatory, antioxidant, antibacterial and analgesic properties. Due to frequent interspecific hybridization, plants collected in the wild display a diverse and variable content of active compounds. This poses a challenge in obtaining high quality and homogenous raw material. Application of the in vitro cultures and micropropagation techniques may offer a solution for alternative methods of cultivation. This work presents preliminary results of the implementation of Ch. angustifolium in vitro cultures to obtain raw material for the first time. Sterile seedlings were donors of explants, which were used for induction of multi-shoots culture according to a modified Turker’s protocol. Six different genotypes (lines) originating from root explants were chosen for clonal propagation. Efficiency of the elaborated method was 16 – 20 shoots per explants. Finally, over 3000 acclimatized plants were obtained and used for field crops.

description: We present results from a spectroscopic Spitzer and Herschel mid-to-far-infrared study of the circumbinary disk orbiting the evolved (age ~12-23 Myr) close binary T Tauri system V4046 Sgr. Spitzer IRS spectra show emission lines of [Ne II], H_2 S(1), CO_2 and HCN, while Herschel PACS and SPIRE spectra reveal emission from [O I], OH, and tentative detections of H_2O and high-J transitions of CO. We measure [Ne III]/[Ne II] < 0.13, which is comparable to other X-ray/EUV luminous T Tauri stars that lack jets. We use the H_2 S(1) line luminosity to estimate the gas mass in the relatively warm surface layers of the inner disk. The presence of [O I] emission suggests that CO, H_2O, and/or OH is being photodissociated, and the lack of [C I] emission suggests any excess C may be locked up in HCN, CN and other organic molecules. Modeling of silicate dust grain emission features in the mid-infrared indicates that the inner disk is composed mainly of large (r~5 um) amorphous pyroxene and olivine grains (~86% by mass) with a relatively large proportion of crystalline silicates. These results are consistent with other lines of evidence indicating that planet building is ongoing in regions of the disk within ~30 AU of the central, close binary.

description: Habitat loss is a primary threat to biodiversity in the present day, causing many species to become endangered or extinct (Cobb 2010).  Migratory birds may be especially vulnerable to habitat loss, since they rely on the persistence of two quality habitats for breeding and wintering (Taylor and Stuchbury 2016). Biologists often dedicate their research to describing patterns of distribution and abundance of species based on habitat variables, which can inform management practices and conservation efforts.  Research on the habitat preferences of species in decline is needed to help prevent future extinctions.

description: Recent theoretical studies have shown that demographic stochasticity can greatly increase the tendency of asexually reproducing phenotypically diverse organisms to spontaneously evolve into localised clusters, suggesting a simple mechanism for sympatric speciation. Here we study the role of demographic stochasticity in a model of competing organisms subject to assortative mating. We find that in models with sexual reproduction, noise can also lead to the formation of phenotypic clusters in parameter ranges where deterministic models would lead to a homogeneous distribution. In some cases, noise can have a sizeable effect, rendering the deterministic modelling insufficient to understand the phenotypic distribution.

The purpose of this pilot study is to identify perceived barriers among nursing staff regarding implementation of a basal-bolus insulin standard for the management of inpatient hyperglycemia in hospitals and test a mixed-methods survey for future quantitative research. The survey tool was designed to obtain unique, self-reported information from practicing inpatient nurses and collect data regarding nurse confidence and familiarity with different types of insulin administration. A convenience sample of nurses from two units in a major medical center was surveyed electronically based upon principles used in similar previous research involving providers. Results indicate that nurses report lower levels of confidence with administration of multiple insulin types than with sliding scale insulin, and that they place a high priority on glycemic treatment and preventing hypoglycemia in patients. Results also indicate that fear of medication errors and causing hypoglycemia were primary nursing barriers among those surveyed. Identified response themes and common barriers have implications for future research, as well as education and policy efforts undertaken by medical centers when instituting basal-bolus insulin regimens as standard practice or hospital policy.

description: We analyze empirical data for 4,000 real-life trading portfolios (U.S. equities) with holding periods of about 0.7-19 trading days. We find a simple scaling C ~ 1/T, where C is cents-per-share, and T is the portfolio turnover. Thus, the portfolio return R has no statistically significant dependence on the turnover T. We also find a scaling R ~ V^X, where V is the portfolio volatility, and the power X is around 0.8-0.85 for holding periods up to 10 days or so. To our knowledge, this is the only publicly available empirical study on such a large number of real-life trading portfolios/alphas.

description: Economic concepts can help farmers evaluate changes needed in their waste management systems to meet the challenges of environmental regulations and of rising energy and fertilizer costs. The concepts of diminishing returns, fixed and variable costs, opportunity costs, budgeting, and amortization are applied to several typical livestock production situations--dairy herds in the Lake States, Southwest, and Southeast; a Corn Belt hog operation and a large confinement hog operation; and a Corn Belt cattle feeder operation. Although more intensive manure management generally preserves more nutrients, additional direct costs of meeting environmental goals or expanding operations exceed nutrient recovery benefits.

description: This article presents a mathematical model for the Enterobacteriaceae count on the surface of broiler chicken during slaughter and how it may be affected by different processing technologies. The model is based on a model originally developed for Campylobacter and has been adapted for Enterobacteriaceae using a Bayesian updating approach and hitherto unpublished data gathered from German abattoirs. The slaughter process in the model consists of five stages: input, scalding, defeathering, evisceration, washing, and chilling. The impact of various processing technologies along the broiler processing line on the Enterobacteriaceae count on the carcasses’ surface has been determined from literature data. The model is implemented in the software R and equipped with a graphical user interface which allows interactively to choose among different processing technologies for each stage along the processing line. Based on the choice of processing technologies the model estimates the Enterobacteriaceae count on the surface of each broiler chicken at each stage of processing. This result is then compared to a so-called baseline model which simulates a processing line with a fixed set of processing technologies. The model calculations showed how even very effective removal of bacteria on the exterior of the carcass in a previous step will be undone by the cross-contamination with leaked feces, if feces contain high concentrations of bacteria.

description: The quark-connected part of the hadronic light-by-light scattering contribution to the muon's anomalous magnetic moment is computed using lattice QCD with chiral fermions. We report several significant algorithmic improvements and demonstrate their effectiveness through specific calculations which show a reduction in statistical errors by more than an order of magnitude. The most realistic of these calculations is performed with a near-physical, $171$ MeV pion mass on a $(4.6\;\mathrm{fm})^3$ spatial volume using the $32^3\times 64$ Iwasaki+DSDR gauge ensemble of the RBC/UKQCD Collaboration.

description: In this article we shed light on newly emerging perspectives to characterize and understand the interplay of diffusive mass transport and surface catalytic processes in pores of gas phase metal catalysts. As a case study, nanoporous gold, as an interesting example exhibiting a well-defined pore structure and a high activity for total and partial oxidation reactions is considered. PFG NMR (pulsed field gradient nuclear magnetic resonance) measurements allowed here for a quantitative evaluation of gas diffusivities within the material. STEM (scanning transmission electron microscopy) tomography furthermore provided additional insight into the structural details of the pore system, helping to judge which of its features are most decisive for slowing down mass transport. Based on the quantitative knowledge about the diffusion coefficients inside a porous catalyst, it becomes possible to disentangle mass transport contributions form the measured reaction kinetics and to determine the kinetic rate constant of the underlying catalytic surface reaction. In addition, predictions can be made for an improved effectiveness of the catalyst, i.e., optimized conversion rates. This approach will be discussed at the example of low-temperature CO oxidation, efficiently catalysed by npAu at 30 °C. The case study shall reveal that novel porous materials exhibiting well-defined micro- and mesoscopic features and sufficient catalytic activity, in combination with modern techniques to evaluate diffusive transport, offer interesting new opportunities for an integral understanding of catalytic processes.

description: Thirty years after their publication, Gilles Deleuze's Cinema 1: The Movement-Image (1983) and Cinema 2: The Time-Image (1985) remain seminal works in the philosophy of cinema. While much current research within film studies is interdisciplinarily-informed, cinema's relevance for philosophy has been largely ignored. This issue discusses the philosophical importance of Deleuze's Cinema books.

Assisting Children's Memories of Their Early Acute Care Hospital Experiences Following Traumatic Brain Injury
Creators: name: Clay, Taylor
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Purpose: The aim of this study is to highlight the importance of collecting patient care diaries, pictures, and other narrative accounts to fill in children’s memory gaps from their early acute care period following severe TBI and to determine factors that influence children’s perceptions of these interventions.vBackground: Many times, children with TBI are admitted to the ICU following their injury. Although early acute care is aimed at stabilizing the patient’s physical condition, many children are left with long-term negative psychological outcomes due to their gaps in memory from this time. Therefore, interventions have been developed to help prevent long-term negative psychological outcomes. Methods: A secondary analysis was employed using interview transcripts from a previous study focusing on children’s experiences following moderate to severe TBI. Transcripts from children with severe TBI were evaluated to see how they viewed such interventions. Three participants from the original study were selected as exemplars of the three types of responses received (positive, negative, or mixed), and their interview transcripts were analyzed to determine how they perceived the utility of interventions used to fill in their memory gaps. Findings: Each of the three subjects from the original study had varying perceptions on the benefits of the interventions used to fill in their memory gaps. While 13 of the children from the original study were not exposed to such interventions, participants who were exposed found that the use of pictures with written or narrative accounts of their early acute care period had positive perceptions of filling in their memory gaps. Conclusions: Participants viewed the use of pictures in addition to other written and verbal accounts as a helpful way of connecting their past to their present. Therefore, it is important to consider pictures and other narrative accounts to improve children’s long-term psychological outcomes following severe TBI. However, it is important to be careful to allow the child to choose whether they would find these interventions helpful.
No county is an island: the rise of interjurisdictional cooperation among counties in China

description: Why are China’s notoriously competitive local governments increasingly cooperating with each other? Combining interjurisdictional cooperation data from 820 counties and fieldwork in 24 localities, we argue that the increasing trend of inter-county cooperation is the newest manifestation of China’s state-rescaling initiative. It is the combined result of the state’s devolution of governance responsibilities and competitive-minded local cadres’ interests in benefits associated with scaling up. The study contributes to understanding how counties’ growing interdependence intersects with the regime’s survival logic in the unfolding reconfiguration of China’s counties.
