description: We study the possibility of determining the quark content of the scalar mesons a0(980) and f0(980) through their hydrodynamical flow signature in relativistic heavy ion collisions. Utilizing the constituent quark scaling of hydrodynamic flow, we find that the tetraquark a0(980) or f0(980) mesons will have a v_2 of 0.38 at transverse momentum of 6 GeV/c in 20-60% central Au+Au collisions at sqrt(s_NN) = 200 GeV. The feasibility of measuring a0(980)-->pi0 + eta and f0(980)-->pi+ + pi- into the PHENIX and STAR detectors at the Relativistic Heavy Ion Collider (RHIC) is also discussed. Even though the mid-rapidity cross sections for these mesons at high-pT are non-negligible, their broad mass range will make them difficult to detect in both p+p and Au+Au collisions.

description: Previous studies have shown that infection of gut tissues (esophagus-stomach-duodenum-colon) by HIV is compartmentalized with increased HIV-1 diversity and selection for drug resistance in the colon. We looked at the kinetics of HIV-1 in the gut tissues obtained from infected patients receiving ART (i.e AZT or ddI). We established real- time PCR protocols to detect HIV-1 proviral DNA forms. The total HIV-1 proviral DNA was the most frequent form found in the gut tissues. 2-LTR proviral DNA was also detected but in low levels which might indicate low viral replication. HIV-1 latent infection was also detected in the gut tissues as represented by the integrated proviral DNA levels. The levels detected of the proviral DNA forms varied between gut tissues, visits and patients, and no difference or correlation were found for patients receiving AZT or ddI.

description: Cerebral amyloid angiopathy (CAA) occurs when the protein, beta-amyloid, deposits onto blood vessels in the brain, often resulting in cognitive impairment. This study aims to identify the neuropsychological profile of CAA by comparing CAA participants to the normal population and cognitively-similar patient populations, distinguishing between CAA syndromes, and determining whether white matter hyperintensity volume or APOE ε4 mediate cognitive impairment. Thirty-four CAA, 16 Alzheimer’s disease, 69 mild cognitive impairment, and 27 minor ischemic stroke participants underwent neuropsychological testing. Cross-sectional data revealed lower performance on tests of perceptual speed, episodic memory, and executive functioning in CAA participants when compared to the normal population (t(33) = -3.76, p = <0.001; t(32) = -2.45, p = 0.02; t(33) = -6.21, p = <0.001; respectively). Overall, CAA was most cognitively similar to vascular cognitive impairment. Larger sample sizes and longitudinal analyses in future will help to advance understanding of cognitive deficits associated with CAA.

description: Astrophysical fluids may acquire non-zero electrical charge because of strong irradiation or charge separation in a magnetic field. In this case, electromagnetic and gravitational forces may act together and produce new equilibrium configurations, which are different from the uncharged ones. Following our previous studies of charged test particles and uncharged perfect fluid tori encircling compact objects, we introduce here a simple test model of a charged perfect fluid torus in strong gravitational and electromagnetic fields. In contrast to ideal magnetohydrodynamic models, we consider here the opposite limit of negligible conductivity, where the charges are tied completely to the moving matter. This is an extreme limiting case which can provide a useful reference against which to compare subsequent more complicated astrophysically-motivated calculations. To clearly demonstrate the features of our model, we construct three-dimensional axisymmetric charged toroidal configurations around Reissner-Nordström black holes and compare them with equivalent configurations of electrically neutral tori.

The genetic control of petal morphology in the sweet pea (Lathyrus odoratus)
Creators: name: Woollacott, Christine Marie
Publisher: name: University of British Columbia
Year: 2010

description: The hooded mutant of sweet pea (Lathyrus odoratus) was characterized in order to better understand the genetic control of petal morphology in papilionoid legumes. The TCP identity gene CYCLOIDEA2 (CYC2) was shown to have different amplification patterns in the standard petals of hooded and wild-type sweet peas in RT-PCR experiments. Lathyrus CYC1 was also examined, but no differences were found between expression patterns in wild-type and hooded plants. Genome walking and additional sequencing revealed that the hooded phenotype was associated with a mutant allele of CYC2. To determine if the mutant allele of CYC2 is responsible for the hooded phenotype, a F2 segregation experiment was conducted. In a population of 118 plants, the hooded phenotype segregated with the mutant allele of CYC2 100% of the time, suggesting that the mutation in CYC2 is likely responsible for the hooded floral character. Scanning Electron Microscopy was conducted to determine if epidermal cell types could be used as micromorphological markers for petal identity. Cells on the adaxial surface of sweet pea petals can be used to distinguish petal identity. When mutant and wild-type flowers were compared, clear differences in cell type were observed. The standard petal in hooded flowers has taken on wing petal characteristics, indicating that the mutation is caused by a shift in petal identity. To examine localized growth patterns in wild-type and hooded flowers, microscopic grids were printed on the surfaces of sweet pea buds using a specialized inkjet apparatus. The deformation of the printed grid during growth allowed localized patterns of growth to be visualized. Wild-type standard petals have a more uniform rate of growth, whereas hooded standard petals show increased growth at their margins which may account for the overall differences in curvature between wild-type and hooded petals. The results of these analyses suggest that the hooded mutant of sweet pea is caused by a mutation in the CYC2 gene. CYC2 genes have been shown to play a role in establishing standard petal identity in the sweet pea and in a number of other legumes (Feng et al., 2006; Wang et al., 2008a).

description: One of the most critical parameters of logistics processes is to measure the efficiency of delivery of the final product to the customer, or last mile processes. Historically, the customer does not care about the processes that are carried out before delivering the product, the end customer is interested in the product reaching their hands on the promised date. The measurement of the efficiency of the logistics processes transit time is necessary to analyse it partially by the different processes and the entities that intervene, from suppliers, manufacturing centres, distribution centres, and carriers. The design of the layout to collect the information allows statistical analysis to evaluate the performance in each part of the process and the generation of algorithms to predict different compartments that can be potentially negative for the fulfilment of the product delivery promise times. The current investigation shows the application of statistical models for predicting delivery errors and delays in delivery in the last mile process in logistics.
title: Fault damage zone volume and initial salinity distribution determine intensity of shallow aquifer salinisation in subsurface storage
Creators: name: Tillner, Elena

Publisher: name: Universität Potsdam

description: Injection of fluids into deep saline aquifers causes a pore pressure increase in the storage formation, and thus displacement of resident brine. Via hydraulically conductive faults, brine may migrate upwards into shallower aquifers and lead to unwanted salinisation of potable groundwater resources. In the present study, we investigated different scenarios for a potential storage site in the Northeast German Basin using a three-dimensional (3-D) regional-scale model that includes four major fault zones. The focus was on assessing the impact of fault length and the effect of a secondary reservoir above the storage formation, as well as model boundary conditions and initial salinity distribution on the potential salinisation of shallow groundwater resources. We employed numerical simulations of brine injection as a representative fluid.

Our simulation results demonstrate that the lateral model boundary settings and the effective fault damage zone volume have the greatest influence on pressure build-up and development within the reservoir, and thus intensity and duration of fluid flow through the faults. Higher vertical pressure gradients for short fault segments or a small effective fault damage zone volume result in the highest salinisation potential due to a larger vertical fault height affected by fluid displacement. Consequently, it has a strong impact on the degree of shallow aquifer salinisation, whether a gradient in salinity exists or the saltwater-freshwater interface lies below the fluid displacement depth in the faults. A small effective fault damage zone volume or low fault permeability further extend the duration of fluid flow, which can persist for several tens to hundreds of years, if the reservoir is laterally confined. Laterally open reservoir boundaries, large effective fault damage zone volumes and intermediate reservoirs significantly reduce vertical brine migration and the potential of freshwater salinisation because the origin depth of displaced brine is located only a few decametres below the shallow aquifer in maximum.

The present study demonstrates that the existence of hydraulically conductive faults is not necessarily an exclusion criterion for potential injection sites, because salinisation of shallower aquifers strongly depends on initial salinity distribution, location of hydraulically conductive faults and their effective damage zone volumes as well as geological boundary conditions.

description: We report the first study on the optical force exerted by an evanescent wave on a small sphere with both electric and magnetic response to the incident field, immersed in an arbitrary nondissipative medium. New expressions and effects from their gradient, radiation pressure, and curl components are obtained due to the particle induced electric and magnetic dipoles, as well as to their mutual interaction. We predict possible dramatic changes in the force depending on either the host medium, the polarization and the nature of the surface wave.

description: Vertical seismic pro le (VSP) data provide a means to estimate the seismic wavelet at different receiver depths. The downgoing wavefi eld has always been the key to measure attenuation (Q) and enables us to correct for the effects of seismic attenuation on seismic data. We demonstrate that we can also use the upgoing wave field to estimate Q, using reflections and mode-converted waves. In this work, Q is estimated from synthetic VSP downgoing and upgoing wavefi elds by using the spectral matching method. We also estimated Q, using the spectral matching method, from VSP data collected in a 500 m deep well in a heavy oil field and a 2000 m deep well in a shale gas play in Western Canada. For the first case, we obtained values of Qp of approximately 50 and Qs of 20 for the strata intersected by the well. For the second case, we obtained values of Qp of approximately 50 and Qs of 30. In the case of Qs estimations, our results indicate that using the upgoing converted wave field provides good estimations when downgoing S-wave are not available in the data.

description: The influence of a changing glass topology on local mechanical properties was studied in a multitechnique nanomechanical approach. The glass response against sharp contacts can result in structural densification, plastic flow, or crack initiation. By using instrumented indentation testing, the mechanical response was studied in different strain rate regimes for a sodium borosilicate glass (NBS) exhibiting altering structures due to varying processing conditions. Comparison with data from former studies and with literature data on other glass structures helped to elucidate the role of the borate and silicate subnetworks and to understand the overall mechanical properties of the mixed glass systems. A peculiarity of some of the NBS glasses tested in this study is the fact that the connectivity of the borate and silicate entities depends on the sample’s thermal history. Although the influence on macroscopic material properties such as E and H is minor, the onset of cracking indeed is influenced by those structural changes within the glass. Rapidly quenched glass shows an improved crack resistance, which is even more pronounced at high strain rates. Studies on various processing conditions further indicate that this transition is closely related to the cooling rate around Tg. The strain rate dependence of cracking is discussed in terms of the occurrence of shear deformation and densification.

description: Alzheimer's disease is a progressive, chronic fatal disease of the brain where the amyloid beta (Aβ) peptide appears in its oligomeric forms, which are known to be neurotoxic. One way to stop this neurotoxicity is to prevent self-oligomerization of Aβ peptide. In the literature, it was shown that Aβ binds to itself in the region of Aβ (13-23) referred as the self-recognition site (Rec). In our lab, several pseudopeptides (referred as Ligands) were designed to bind with Aβ (13-23). Computational chemistry techniques such as Molecular Dynamics Simulations and Umbrella Sampling have been utilized to characterize the Ligands that are intended to bind selectively to the Rec. It has been observed that the Ligands bind to Rec, Aβ (13-23), and they are competitive with it, suggesting that these Ligands can compete with the full length of Aβ as well. Thus, they could be considered as “drug” candidates to stop Aβ oligomerization.

The resonator was required to achieve the voltages necessary to trap (about 100 V), while dissipating as little power as possible (< 250 mW). Ultimately a voltage gain of 100 was measured at 5.7 K. Single calcium ions were confined in a trap driven by this device, providing proof of successful resonator operation at low temperature.

description: In the field of hairpin stator technology, increasing demands are currently being made on the semi-finished product of insulated flat copper wire. In particular, the focus is on the electrical requirements against the background of increasing voltage levels to 800 V and more. The test procedures described in the standards IEC 60317 & 60851 for verifying the properties of insulated flat copper wires only partially map the requirements from the point of automotive industry. An example for insufficiently considered properties lays in the correlation between wire and insulation resin. In addition to electrical and thermal benefits, impregnation helps to mechanically stabilize the winding and protect it from ambient factors. Adhesion between the winding and the impregnating resin is a key parameter here, but is not considered in material pre-selection today. The adhesion of the impregnation resin to the insulated wire is essential to ensure the lifetime of electric motors. This paper describes a method for determining the adhesion of the impregnating resin to the insulation of the wire. It could be shown that there is a correlation between the material of the wire insulation and the impregnating resin in terms of adhesion. Further on the described method can be used for an application-oriented specification of insulated copper flat wires to ensure a consistent composition of the insulation material.

description: In order to put MIDI/VLTI observations of AGNs on a significant statistical basis, the number of objects had to be increased dramatically from the few prominent bright cases to over 20. For this, correlated fluxes as faint as ~ 150 mJy need to be observed, calibrated and their errors be estimated reliably. We have developed new data reduction methods for the coherent estimation of correlated fluxes with the Expert Work Station (EWS). They increase the signal/noise of the reduced correlated fluxes by decreasing the jitter in the group delay estimation. While correlation losses cannot be fully avoided for the weakest objects even with the improved routines, we have developed a method to simulate observations of weak targets and can now detect --- and correct for --- such losses. We have analyzed all sources of error that are relevant for the observations of weak targets. Apart from the photon-noise error, that is usually quoted, there is an additional error from the uncertainty in the calibration (i.e. the conversion factor). With the improved data reduction, calibration and error estimation, we can consistently and reproducibly observe fluxes as weak as ~ 150 mJy with an uncertainty of ~ 15 % under average conditions.

description: The new sediment record from the deep Dead Sea basin (ICDP core 5017-1) provides a unique archive for hydroclimatic variability in the Levant. Here, we present high-resolution sediment facies analysis and elemental composition by micro-X-ray fluorescence (mu XRF) scanning of core 5017-1 to trace lake levels and responses of the regional hydroclimatology during the time interval from ca. 117 to 75 ka, i. e. the transition between the last interglacial and the onset of the last glaciation. We distinguished six major micro-facies types and interpreted these and their alterations in the core in terms of relative lake level changes. The two end-member facies for highest and lowest lake levels are (a) up to several metres thick, greenish sediments of alternating aragonite and detrital marl laminae (aad) and (b) thick halite facies, respectively. Intermediate lake levels are characterised by detrital marls with varying amounts of aragonite, gypsum or halite, reflecting lower-amplitude, shorter-term variability. Two intervals of pronounced lake level drops occurred at similar to 110-108 +/- 5 and similar to 93-87 +/- 7 ka. They likely coincide with stadial conditions in the central Mediterranean (Melisey I and II pollen zones in Monticchio) and low global sea levels during Marine Isotope Stage (MIS) 5d and 5b. However, our data do not support the current hypothesis of an almost complete desiccation of the Dead Sea during the earlier of these lake level low stands based on a recovered gravel layer. Based on new petrographic analyses, we propose that, although it was a low stand, this well-sorted gravel layer may be a vestige of a thick turbidite that has been washed out during drilling rather than an in situ beach deposit. Two intervals of higher lake stands at similar to 108-93 +/- 6 and similar to 87-75 +/- 7 ka correspond to interstadial conditions in the central Mediterranean, i. e. pollen zones St. Germain I and II in Monticchio, and Greenland interstadials (GI) 24+23 and 21 in Greenland, as well as to sapropels S4 and S3 in the Mediterranean Sea. These apparent correlations suggest a close link of the climate in the Levant to North Atlantic and Mediterranean climates during the time of the build-up of Northern Hemisphere ice shields in the early last glacial period.

Abstract  The orally active hypoxia inducible factor-proly hydroxylase (HIF-PH) inhibitor enarodustat (ENAROY®, Japan Tobacco) is being developed as an alternative to injectable erythropoietin stimulating agents such as epoetin and darbepoetin for the treatment of anaemia associated with chronic kidney disease (CKD). The drug is approved in Japan and clinical development is ongoing in the USA and South Korea. This article summarizes the milestones in the development of enarodustat leading to this first approval for anaemia associated with CKD.

description: Exact solutions to the d-dimensional Schroedinger equation, d\geq 2, for Coulomb plus harmonic oscillator potentials V(r)=-a/r+br^2, b>0 and a\ne 0 are obtained. The potential V(r) is considered both in all space, and under the condition of spherical confinement inside an impenetrable spherical box of radius R. With the aid of the asymptotic iteration method, the exact analytic solutions under certain constraints, and general approximate solutions, are obtained. These exhibit the parametric dependence of the eigenenergies on a, b, and R. The wave functions have the simple form of a product of a power function, an exponential function, and a polynomial. In order to achieve our results the question of determining the polynomial solutions of the second-order differential equation (\sum_{i=0}^{k+2}a_{k+2,i}r^{k+2-i})y"+(\sum_{i=0}^{k+1}a_{k+1,i}r^{k+1-i})y'-(\sum_{i=0}^{k}τ_{k,i}r^{k-i})y=0 for k=0,1,2 is solved.

description: Traditional tests of hypotheses on the cointegrating vector are well known to suffer from severe size distortions in finite samples, especially when the data are characterized by large levels of endogeneity or error serial correlation. To address this issue, we combine a vector autoregressive (VAR) sieve bootstrap to construct critical values with a self-normalization approach that avoids direct estimation of long-run variance parameters when computing test statistics. To asymptotically justify this method, we prove bootstrap consistency for the self-normalized test statistics under mild conditions. In addition, the underlying bootstrap invariance principle allows us to prove bootstrap consistency also for traditional test statistics based on popular modified OLS estimators. Simulation results show that using bootstrap critical values instead of asymptotic critical values reduces size distortions associated with traditional test statistics considerably, but combining the VAR sieve bootstrap with self-normalization can lead to even less size distorted tests at the cost of only small power losses. We illustrate the usefulness of the VAR sieve bootstrap in empirical applications by analyzing the validity of the Fisher effect in 19 OECD countries.

description: The eukaryotic protein Isd11 is a chaperone that binds and stabilizes the central component of the essential metabolic pathway responsible for formation of iron-sulfur clusters in mitochondria, the desulfurase Nfs1. Little is known about the exact role of Isd11. Here, we show that human Isd11 (ISD11) is a helical protein which exists in solution as an equilibrium between monomer, dimeric and tetrameric species when in the absence of human Nfs1 (NFS1). We also show that, surprisingly, recombinant ISD11 expressed in E. coli co-purifies with the bacterial orthologue of NFS1, IscS. Binding is weak but specific suggesting that, despite the absence of Isd11 sequences in bacteria, there is enough conservation between the two desulfurases to retain a similar mode of interaction. This knowledge may inform us on the conservation of the mode of binding of Isd11 to the desulfurase. We used evolutionary evidence to suggest Isd11 residues involved in the interaction.

description: This research puts forth a graphical user interface for interacting with and modifying conversations used by software agents in a Multi Agent System (MAS) architecture (CASA). MAS Communications is a field of Artificial Intelligence focusing on improving the way agents communicate. Thus message exchanges are made meaningful by implementing concepts surrounding context. Additionally, they should be flexible in order to avoid problems due to unpredictability. Lastly, these paradigms should be simple to ease their adoption. Using this interface one can visualize how different conversations progress and why they do so allowing for the identification of error sources in the system. The user can also modify existing conversation types, create new ones, and instantiate implementations of them for individual agents. The conversation types are typically distinguished by what is called the performative of the communicative act. This is a concept adopted from linguistics where the performative indicates a conversation's intent/desires.

description: This study investigates phenomena that have been claimed to be indicative of Specific Language Impairment (SLI) in German, focusing on subject-verb agreement marking. Longitudinal data from fourteen German-speaking children with SLI, seven monolingual and seven Turkish-German successive bilingual children, were examined. We found similar patterns of impairment in the two participant groups. Both the monolingual and the bilingual children with SLI had correct (present vs. preterit) tense marking and produced syntactically complex sentences such as embedded clauses and wh-questions, but were limited in reliably producing correct agreement-marked verb forms. These contrasts indicate that agreement marking is impaired in German-speaking children with SLI, without any necessary concurrent deficits in either the CP-domain or in tense marking. Our results also show that it is possible to identify SLI from an early successive bilingual child's performance in one of her two languages.

description: Much previous experimental research on morphological processing has focused on surface and meaning-level properties of morphologically complex words, without paying much attention to the morphological differences between inflectional and derivational processes. Realization-based theories of morphology, for example, assume specific morpholexical representations for derived words that distinguish them from the products of inflectional or paradigmatic processes. The present study reports results from a series of masked priming experiments investigating the processing of inflectional and derivational phenomena in native (L1) and non-native (L2) speakers in a non-Indo-European language, Turkish. We specifically compared regular (Aorist) verb inflection with deadjectival nominalization, both of which are highly frequent, productive and transparent in Turkish. The experiments demonstrated different priming patterns for inflection and derivation, specifically within the L2 group. Implications of these findings are discussed both for accounts of L2 morphological processing and for the controversial linguistic distinction between inflection and derivation.

description: Two experiments tested how faithfully German children aged 4; 5 to 5; 6 reproduce ditransitive sentences that are unmarked or marked with respect to word order and focus (Exp1) or definiteness (Exp2). Adopting an optimality theory (OT) approach, it is assumed that in the German adult grammar word order is ranked lower than focus and definiteness. Faithfulness of children's reproductions decreased as markedness of inputs increased; unmarked structures were reproduced most faithfully and unfaithful outputs had most often an unmarked form. Consistent with the OT proposal, children were more tolerant against inputs marked for word order than for focus; in conflict with the proposal, children were less tolerant against inputs marked for word order than for definiteness. Our results suggest that the linearization of objects in German double object constructions is affected by focus and definiteness, but that prosodic principles may have an impact on the position of a focused constituent.

description: Arctic tundra ecosystems have experienced unprecedented change associated with climate warming over recent decades. Across the Pan-Arctic, vegetation productivity and surface greenness have trended positively over the period of satellite observation. However, since 2011 these trends have slowed considerably, showing signs of browning in many regions. It is unclear what factors are driving this change and which regions/landforms will be most sensitive to future browning. Here we provide evidence linking decadal patterns in arctic greening and browning with regional climate change and local permafrost-driven landscape heterogeneity. We analyzed the spatial variability of decadal-scale trends in surface greenness across the Arctic Coastal Plain of northern Alaska (similar to 60,000 km(2)) using the Landsat archive (1999-2014), in combination with novel 30 m classifications of polygonal tundra and regional watersheds, finding landscape heterogeneity and regional climate change to be the most important factors controlling historical greenness trends. Browning was linked to increased temperature and precipitation, with the exception of young landforms (developed following lake drainage), which will likely continue to green. Spatiotemporal model forecasting suggests carbon uptake potential to be reduced in response to warmer and/or wetter climatic conditions, potentially increasing the net loss of carbon to the atmosphere, at a greater degree than previously expected.

description: Entanglement is one of the essential resources in quantum information and communication technology (QICT). The entanglement thus far explored and applied to QICT has been pure and distillable entanglement. Yet there is another type of entanglement, called 'bound entanglement', which is not distillable by local operations and classical communication (LOCC). We demonstrate the experimental 'activation' of the bound entanglement held in the four-qubit Smolin state, unleashing its immanent entanglement in distillable form, with the help of auxiliary two-qubit entanglement and LOCC. We anticipate that it opens the way to a new class of QICT applications that utilize more general classes of entanglement than ever, including bound entanglement.
