description: High emissions of nitrogen to the environment are one of the major drawbacks of modern agriculture. Subsurface drip fertigation (SDF) is a technology to apply fertilizer in small amounts continuously and directly into the root zone with the potential of mitigating deep percolation losses when accurately managed. Our study was established to analyze possible benefits of SDF, i.e. nitrate losses reduction without decrease in yield, as alternative to the conventional application of nitrogen fertilizer. In this five-year field study, effects of SDF on red cabbage (Brassica oleracea) growth, yield, root distribution and nitrogen uptake were evaluated. The experiments took place in northern Germany. Application of fertilizer in a solution with water was managed to match the needs of crops and placed directly in the root zone through permanently buried driplines. The outcomes of crop growth under SDF were compared with a control crop receiving fertilizer at one or two dates by surface broadcasting. Yield and agronomic nitrogen use efficiency were higher for crops grown under SDF. Total dry mass increase was especially high under dry conditions (34%) but as well under wet conditions with efficient management (20%). Head dry mass of crops grown under SDF had a stronger reaction to the available nitrogen than crops under conventional application, with values of 0.19 and 0.1 Mg ha-1 per kg N ha-1 respectively. Moreover, SDF treatment resulted on average ca. 14 kg ha−1 higher nitrogen uptake. In SDF plots, yield formation and nitrogen uptake was higher for plants grown directly above drip lines. Effect of the distance to nitrogen source was supported with numerical simulations. The root structure showed different distributions for the two treatments, particularly in years with low rainfall. Overall, the results showed the potential of SDF to effectively control nitrogen supply, thereby increasing yield formation of marketable plant organs.

description: We report on a Monte Carlo study of the lowest-Landau-level limit of the Lawrence-Doniach model for a layered superconductor. We have studied order parameter correlation functions for indications of the broken translational symmetry and the off-diagonal long range order present in the mean-field-theory vortex lattice. Our results are consistent with a single first order phase transition between a low temperature 3D vortex solid phase, with both broken translational symmetry and off-diagonal long range order, and a high temperature vortex liquid phase with no broken symmetries. We construct a universal phase diagram in terms of dimensionless parameters characterizing intra-layer and inter-layer couplings. The universal phase boundary extracted from our simulations and the associated latent heats and magnetization jumps are compared with experiment and with numerical results obtained for related models.

description: The production of concrete and especially of cement clinker is associated with significant CO2 emissions. In order to reduce these emissions, various measures have been introduced in recent years, including energy efficiency, the use of alternative fuels, and the replacement of Portland cement clinker by supplementary cementitious materials (SCM). Here, the performance and the environmental impact of so-called eco-efficient concretes with a strongly reduced clinker content as low as 20 wt% of cement, blended with limited contents of slag – reflecting the fact that also slag is a limited resource – and high contents of limestone powder are discussed. In addition, the fineness of the slag in the ternary blended cements was systematically varied. The properties in the fresh state, the mechanical and durability properties as well as the environmental impact of these eco-efficient concretes are determined. Results show that the fineness of the binder components, in this case the slag fineness, has a significant effect on the hydration kinetics and the resulting mechanical performance as well as the durability properties of eco-efficient concretes. Finer grinding of the slag significantly improves the performance of clinker-efficient cements. Concretes with clinker contents in the cement as low as 30 wt% and high limestone powder contents of up to 40 wt% proofed to be suitable for structural concrete. The CO2 footprint is reduced because the replaced clinker compensates the additional emissions (higher energy consumption) associated with grinding. This enables efficient use of the binder while reducing the clinker content and replacing it with less reactive and lower-emission materials.

description: We present a set of integer programs (IPs) for the Steiner tree problem with the property that the best solution obtained by solving all, provides an optimal Steiner tree. Each IP is polynomial in the size of the underlying graph and our main result is that the linear programming (LP) relaxation of each IP is integral so that it can be solved as a linear program. However, the number of IPs grows exponentially with the number of terminals in the Steiner tree. As a consequence, we are able to solve the Steiner tree problem by solving a polynomial number of LPs, when the number of terminals is fixed.

description: We study maximally symmetric cosmological solutions of type II supersymmetric strings in the presence of the exact quartic curvature corrections to the lowest order effective action, including loop and D-instanton effects. We find that, unlike the case of type IIA theories, de Sitter solutions exist for type IIB superstrings, a conclusion that remains valid when higher-curvature corrections are included on the basis of SL(2,Z) invariance.

Narrating the Individual and the Community in Elizabeth Gaskell's Cranford
Creators: name: Koustinoudi, Anna
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2010

description: My reading of Elizabeth Gaskell's community narrative Cranford (1853) addresses the novel's idiosyncratic narrative form in terms of how it gen­erates tensions between the individual and the community. Cranford, the text, and Cranford, the place, inform each other mutually through the me­diation of Mary Smith, the text's communal, and thus, liminal narrator. As a narrator, Mary Smith operates in her capacity as an individual, de­tached observer/ recorder of her narrated world, as a distinct "I" address­ing an urban, middle-class audience. As a character, however, she often resorts to the convenient all-inclusiveness of a "we," through which she becomes and speaks as part of Cranford' s rural community in an attempt to recompense the text's characters for her ironic narrative stance and mild aggression. Caught between her dual role and structural positioning as both insider and outsider of the community she depicts, Gaskell's narrator holds a borderline position of in-betweenness, which renders the relation between the "I" and the "we" a deeply conflictual, but, at the same time, a mutually constitutive and transactional one.

description: We have combined the original diffusion-limited aggregation model introduced by Witten and Sander with the surface thermodynamics of the growing solid aggregate. The theory is based on the consideration of the surface chemical potential as a thermodynamic function of the temperature and nearest-neighbor configuration. The Monte Carlo simulations on a two-dimensional square lattice produce the broad range of shapes such as fractal dendritic structures, densely branching patterns, and compact aggregates. The morphology diagram illustrating the relationship between the model parameters and cluster geometry is presented and discussed.

description: Magnetometry is an important tool prevalent in many applications such as fundamental research, material characterization and biological imaging. Atomic magnetometry conventionally makes use of two quantum states, the energy difference of which depends linearly on the magnetic field due to the Zeeman effect. The magnetic field is evaluated from repeated measurements of the accumulated dynamic phase between the two Zeeman states in a superposition. Here we propose a magnetometry method that employs a superposition of clock states with energies that do not depend, to first-order, on the magnetic field magnitude. Our method makes use of the geometrical dependence of the clock-states wavefunctions on the magnetic field orientation. We propose detailed schemes for measuring both static and time-varying magnetic fields, and analyze the sensitivity of these methods. We show that, similarly to Zeeman-based methods, the smallest measurable signal scales inversely with the system coherence-time, which for clock transitions is typically significantly longer than for magnetically sensitive transitions. Finally, we experimentally demonstrate our method on an ensemble of optically trapped 87Rb atoms.

The Scapegoat in Hardy's Tragic Novels: Revisiting Ancient Theory

description: Tess d'Urberville (Tess of the d'Urbervilles) and Eustacia Vye (The Return of the Native) are tragic scapegoats whose function in the diegesis may be re­visited in the light of Lacanian psychoanalysis. In the field of our reality, there is always "more than meets the eye," because of the exclusion from it of what Lacan has called object small a. Not so in Hardy's tragic world, where the vacuity of the perspective is filled by an object which very nearly presentifies the "object-gaze"—one of the forms of object small a. That object is the heroine herself, who is singled out by a red stain and occupies in the visual field the place that should normally be a vacuum. A feminine figure of "unextracted" jouissance, she is a "spot" that comes in excess of reality, a surplus object whose very presence threatens her community with disin­tegration. Therefore she has to be sacrificed for object small a to be extracted and for the consistency of her community's "reality" to be restored.

description: We report detections of pure rotation lines of OH and H2O in the K1.5 III red-giant star Arcturus (alpha Bootis) using high-resolution, infrared spectra covering the regions 806-822 cm-1 (12.2-12.4 um) and 884-923 cm-1 (10.8-11.3 um). Arcturus is the hottest star yet to show water-vapor features in its disk-averaged spectrum. We argue that the water vapor lines originate from the photosphere, albeit in the outer layers. We are able to predict the observed strengths of OH and H2O lines satisfactorily after lowering the temperature structure of the very outer parts of the photosphere (log tau_500=-3.8 and beyond) compared to a flux-constant, hydrostatic, standard MARCS model photosphere. Our new model is consistently calculated including chemical equilibrium and radiative transfer from the given temperature structure. Possible reasons for a temperature decrease in the outer-most parts of the photosphere and the assumed break-down of the assumptions made in classical model-atmosphere codes are discussed.

description: By coupling the Boltzmann transport equations of both quarkonium and open heavy quarks, we investigate their dynamical evolution inside the quark-gluon plasma and study quarkonium production in heavy ion collisions. The Boltzmann transport equation of quarkonium is derived from the open quantum system formalism and effective field theory of QCD by assuming quarkonium interacts weakly with the plasma. The dissociation and recombination terms in the Boltzmann equation are calculated in potential nonrelativistic QCD. It is shown that the combination of quarkonium dissociation, recombination, open heavy quark diffusion and energy loss can drive the system of quarkonium and open heavy quarks to detailed balance and kinetic thermalization. By solving the transport equations with initial momenta of quarkonia and heavy quarks sampled from PYTHIA and a hydrodynamic medium, we can calculate the nuclear modification factors of bottomonium and describe the data at both RHIC and LHC energies. The azimuthal angular anisotropy coefficient $v_2$ of $Υ$(1S) in 5.02 TeV peripheral Pb-Pb collisions is also predicted.

description: We consider a disordered d--wave superconductor in two dimensions. Recently, we have shown in an exact calculation that for a lattice model with a Lorentzian distributed random chemical potential the quasiparticle density of states at the Fermi level is nonzero. As the exact result holds only for the special choice of the Lorentzian, we employ different methods to show that for a large class of distributions, including the Gaussian distribution, one can establish a nonzero lower bound for the Fermi level density of states. The fact that the tails of the distributions are unimportant in deriving the lower bound shows that the exact result obtained before is generic.

Mediating between the Mass and the Individual: Punch Caricatures of the Great Exhibition of All Nations

Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2010

description: This article is concerned with an analysis of class relations and behavior during the Great Exhibitions of All Nations, the mega-event organized by Prince Albert in May 1851, as illustrated by articles and caricatures pub­lished in Punch, the most famous popular press magazine at the time. Aim­ing at the rising middle-class readership, Punch revealed an underpinning humorous, even critical attitude towards class differentiation and individ­ual representatives, thus depicting both the birth of working-class con­sciousness and the consolidation of a middle-class attitude towards the two extremes of the social scale. Punch's ambivalence in portraying the aristocracy and the working class in "The Pound and the Shilling" cartoon and its colonial, conservative attitude towards the non-Brit in "Perfidious Albion" and "The North-American Lodgers in 1851" are examples to sup­port the argument that individual class consciousness was being molded into mass consciousness at the start of the 1850s in England.

The Paranoid Simulacrum in Surrealism: From Embracing Madness to the Mechanism of a Mental Illness as the Purveyor of Individual Meaning
Creators: name: Constantinidou, Despina-Alexandra
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2010

description: This paper explores the way in which the cultural, psychiatric and psy­choanalytic context of the 1930s acknowledged the potential of a specific mental illness, paranoia, to speak (of) individuality. The French surrealists, in particular, hailed a number of mental illnesses as an attempt at a flight from restrictive conventional meaning, that is meaning sanctified by the group or the mass. Among these mental states, paranoia was singled out by Salvador Dali, who utilized the paranoiac's mechanism of interpreta­tion, in order to contrive a systematic procedure for projecting one's own way of interpreting, that is of assigning meaning to the objects of percep­tion. The paranoid simulacra of Dali' s images of multiple figurations ac­commodated the unconscious of the individual, and were the outcome of the paranoid-critical method of interpretation that he devised. In this, he was assisted by Sigmund Freud's elaboration of paranoia, as well as the attention that paranoia had attracted in the psychiatric circles of 1930s Paris. Jacques Lacan's psychiatric treatise, in particular, was to confirm that the mechanism of the paranoid delirium assigned personal meaning to reality in a way that mediated the unconscious of the individual.

description: Marine structures such as ports, bridges, pipelines, vessels, and platforms are an essential part of modern infrastructure, where the use of higher-strength steel provides savings in logistics and construction. However, the repair of higher-strength steels can be challenging, especially underwater. Wet shielded metal arc welding is the most widely used and least expensive method for underwater welding repairs, but is very susceptible to hydrogen-induced cracking. Thus, researchers and welding engineers aim to reduce the amount of hydrogen in the weld material. Recent success has been achieved through the use of austenitic welding consumables, such as austenitic stainless steel and nickel-based electrodes. The use of these consumables drastically reduces the amount of diffusible hydrogen in the weld metal. However, these austenitic materials usually have different corrosion potential as compared to the structural steel the weld beads are applied to. This creates the risk of severe galvanic corrosion. In the presented study, the corrosion behavior of welds created with austenitic stainless steel and nickel-based electrodes were studied. Samples were aged for 1.5 years in the Baltic Sea. Simultaneously, the effectiveness of corrosion protection systems such as coating and Impressed Current Cathodic Protection (ICCP) were evaluated. Localized corrosion occurred in the heat-affected zone when austenitic electrodes were used in the corrosive environment. The localized corrosion depth after 1.5 years in the Baltic Sea and in the salt spray layer was approximately 250 µm and 390 µm, respectively. The ICCP system and the use of a coating were effective in preventing localized corrosion. The low pitting corrosion density of 2.5 × 103m−2 corresponds to grade A1 according to the standard and was found to be negligible as compared to the localized corrosion in the heat-affect zone.

description: The aim of this article is to examine the socioeconomic conditions that en­able avant-garde artists to work for multinational corporations without sacrificing their individual aesthetic. A close reading of Julie Taymor's crit­ically acclaimed and commercially successful staging of Disney's The Lion King will show that in our predominantly visual late-capitalist societies a sophisticated postdramatic visual aesthetic can be commodified without alienating the mass audiences. This commodification forces us to reevaluate the traditional modernist definitions of art in immanent aesthetic terms in a postmodern culture that witnesses the thorough commodification of high art and the high aestheticization of popular culture. These modifica­tions in the cultural and aesthetic spheres will be analyzed through a Marxist theoretical frame that puts the modernist rigid dichotomies be­tween high and popular art in a historical perspective.

description: Animal models lack physiologic relevance to the human system which results in low clinical translation of results derived from animal testing. Besides spheroids or organoids, hydrogel-based 3D in vitro models are used to mimic the in vivo situation increasing the relevance while reducing animal testing. However, to establish hydrogel-based 3D models in applications such as drug development or personalized medicine, high-throughput culture systems are required. Furthermore, the integration of oxygen-reduced (hypoxic) conditions has become increasingly important to establish more physiologic culture models. Therefore, we developed a platform technology for the high-throughput generation of miniaturized hydrogels for 3D cell culture. The Oli-Up system is based on the shape of a well-plate and allows for the parallel culture of 48 hydrogel samples, each with a volume of 15 µl. As a proof-of-concept, we established a 3D culture of gelatin-methacryloyl (GelMA)-encapsulated mesenchymal stem/stromal cells (MSCs). We used a hypoxia reporter cell line to establish a defined oxygen-reduced environment to precisely trigger cellular responses characteristic of hypoxia in MSCs. In detail, the expression of hypoxia response element (HRE) increased dependent on the oxygen concentration and cell density. Furthermore, MSCs displayed an altered glucose metabolism and increased VEGF secretion upon oxygen-reduction. In conclusion, the Oli-Up system is a platform technology for the high-throughput culture of hydrogel-based 3D models in a defined oxygen environment. As it is amenable for automation, it holds the potential for high-throughput screening applications such as drug development and testing in more physiologic 3D in vitro tissue models.

description: Student's mental health problems have been explored previously in higher education literature in various contexts including empirical work involving quantitative and qualitative methods. Nevertheless, comparatively few research could be found, aiming for computational methods that learn information directly from data without relying on set parameters for a predetermined equation as an analytical method. This study aims to investigate the performance of Machine learning (ML) models used in higher education. ML models considered are Naive Bayes, Support Vector Machine, K-Nearest Neighbor, Logistic regression, Stochastic Gradient Descent, Decision Tree, Random Forest, XGBoost (Extreme Gradient Boosting Decision Tree), and NGBoost (Natural) algorithm. Considering the factors of mental health illness among students, we follow three phases of data processing: segmentation, feature extraction, and classification. We evaluate these ML models against classification performance metrics such as accuracy, precision, recall, F1 score, and predicted run time. The empirical analysis includes two contributions: 1. It examines the performance of various ML models on a survey-based educational dataset, inferring a significant classification performance by a tree-based XGBoost algorithm; 2. It explores the feature importance [variables] from the datasets to infer the significant importance of social support, learning environment, and childhood adversities on a student's mental health illness.
Second-Generation West Indian Women, Television and the Dialogical Self
Creators: name: Gentles-Peart, Kamille
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2010

description: Employing the Bakhtinian concept of the dialogical self, this article exam­ines how second-generation West Indian immigrant women negotiate their multiple cultural and national positions in the United States. Further­more, it examines the manner in which the American media, particularly television, are reflective and constitutive of this process of identity forma­tion. The article speaks to the theme of the journal issue in several ways. It highlights the polyphonic voices in the individual, and how these "selves" influence and are influenced by the cultural communities to which the individual belongs. With the "third world" immigrant as its subject, the article also necessarily addresses the relationship between global/ mi­gratory individuals and their diasporic locales, and explores the individual and collective positioning of non-Western "minorities" in dominant West­ern communities.

description: We present a near-infrared study of the Seyfert 2 galaxy NGC\,6300, based on subarcsecond images and long slit spectroscopy obtained with Flamingos-2 at Gemini South. We have found that the peak of the nuclear continuum emission in the $K_s$ band and the surrounding nuclear disk are 25\,pc off-center with respect to the center of symmetry of the larger scale circumnuclear disk, suggesting that this black hole is still not fixed in the galaxy potential well. The molecular gas radial velocity curve yields a central black hole upper mass estimation of $M_{SMBH}^{upper}=(6\pm 2) \times 10^{7}\,\Msun$. The Pa$β$ emission line has a strongly asymmetric profile with a blueshifted broad component that we associate with a nuclear ionized gas outflow. We have found in the $K_s$-band spectra that the slope of the continuum becomes steeper with increasing radii, which can be explained as the presence of large amounts of hot dust not only in the nucleus but also in the circumnuclear region up to $r=27$\,pc. In fact, the nuclear red excess obtained after subtracting the stellar contribution resembles to that of a blackbody with temperatures around 1200\,K. This evidence supports the idea that absorbing material located around the nucleus, but not close enough to be the torus of the unified model, could be responsible for at least part of the nuclear obscuration in this Seyfert 2 nucleus.

description: BACKGROUND: TALE-derived DddA-based cytosine base editors (TALE-DdCBEs) can perform efficient base editing of mitochondria and chloroplast genomes. They use transcription activator-like effector (TALE) arrays as programmable DNA-binding domains and a split version of the double-strand DNA cytidine deaminase (DddA) to catalyze C•G-to-T•A editing. This technology has not been optimized for use in plant cells. RESULTS: To systematically investigate TALE-DdCBE architectures and editing rules, we established a β-glucuronidase reporter for transient assays in Nicotiana benthamiana. We show that TALE-DdCBEs function with distinct spacer lengths between the DNA-binding sites of their two TALE parts. Compared to canonical DddA, TALE-DdCBEs containing evolved DddA variants (DddA6 or DddA11) showed a significant improvement in editing efficiency in Nicotiana benthamiana and rice. Moreover, TALE-DdCBEs containing DddA11 have broader sequence compatibility for non-TC target editing. We have successfully regenerated rice with C•G-to-T•A conversions in their chloroplast genome, as well as N. benthamiana with C•G-to-T•A editing in the nuclear genome using TALE-DdCBE. We also found that the spontaneous assembly of split DddA halves can cause undesired editing by TALE-DdCBEs in plants. CONCLUSIONS: Altogether, our results refined the targeting scope of TALE-DdCBEs and successfully applied them to target the chloroplast and nuclear genomes. Our study expands the base editing toolbox in plants and further defines parameters to optimize TALE-DdCBEs for high-fidelity crop improvement.
Gravitational Potential Reconstruction from Peculiar Velocity and Weak Lensing Measurements

description: We present an analytic method for rapidly forecasting the accuracy of gravitational potential reconstruction possible from measurement of radial peculiar velocities of every galaxy cluster with M > M_th in solid angle θ^2 and over redshift range z_min < z < z_max. These radial velocities can be determined from measurement of the kinetic and thermal Sunyaev-Zeldovich effects. For a shallow survey with 0.2 < z < 0.4, coincident with the SDSS photometric survey, one mode of the gravitational potential (on length scales > 60 Mpc) can be reconstructed for every ~8 cluster velocity determinations. Deeper surveys require measurement of more clusters per S/N > 1 mode. Accuracy is limited by the ``undersampling noise'' due to our non-observation of the large fraction of mass that is not in galaxy clusters. Determining the gravitational potential will allow for detailed study of the relationship between galaxies and their surrounding large-scale density fields over a wide range of redshifts, and test the gravitational instability paradigm on very large scales. Observation of weak lensing by large-scale structure provides complementary information since lensing is sensitive to the tangential modes that do not affect the velocity.
