De l’exubérance végétale à la prédation animale
Creators: name: Libis, Jean
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Vegetality, Animality, Will to Live, Rêveries

description: It is paradoxically reductive to summarize the bachelardian imaginary of the four fundamental elements. Not only the elements themselves are declined in a variety of materials, but also the bachelardian dynamic is open to the size of a cosmos that can not be reduced to the logic of a quadrangulation. In this context, for the philosopher, the vegetal world also seems to be an inexhaustible source of references and rêveries, which constitute a main pole of meditation. Naturally, references to the plant world appear dispersed in the work of the philosopher: the “aerial tree”, the root, the vine, the water lilies. They are not less multiplied and subtly recurring. Thus Bachelard talks about “notre végétalisme profond” (our deep vegetality).

It is necessary to consider the meaning of this enigmatic formula. And this is even more important since the philosopher has always kept himself to the edge of the animal world, to which, after all, he rarely refers to, and in front of which he repeatedly expresses a kind of surprising reluctance. It may be possible that it is not adapted to what, for Bachelard, is more essential while he proceed with is work to a “philosophie du repos” (philosophy of rest).

We can also make a disturbing hypothesis: is animality, full of the “Will to Live” that Schopenhauer placed at the heart of his system? Is it ontologically close to that troubled humanity the philosopher feels a very ambiguous sympathy for? Bachelardian vegetality would it be the opposite of what we might call problematic humanism?

Poétique de l’arbre et de la forêt. Une lecture bachelardienne de l’œuvre de Jean Giono
Creators: name: Pierron, Jean-Philippe
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Tree, Forest, Ecology, Rêverie of plants, Giono

description: By offering a reading and a perspective of Jean Giono's novel «L’homme qui plantait des arbres» (The Man Who Planted Trees), published in 1953, the following article would show what contributions Gaston Bachelard's philosophy might make to environmental imagination. As Jean Giono writes  “je crois qu’il est grand temps qu’on fasse une ‘politique de l’arbre’ bien que le mot politique semble bien mal adapté ”, we could say that it is time that this politic finds her poetic.

The tree, as a primary image that emphasizes an upward dynamic in L’Air et les songes, and the forest, which rise a poetic of space in Bachelard (friend and reader of Gaston Roupnel, the historian of the French countryside), are precious figures in order to develop a poetic of nature. For this, however, there would be two defies. On the one hand, if the choice made by Gaston Bachelard to retain the tetralogy of the ancient cosmology produces a shift in thinking about the rêverie du végétal, an inadequacy in the valuation of the mineral on the organic, it doesn’t preclude it in principle. The phénoménologie du vegetal (phenomenology of plants) led to wonder what is about its relative neglected in the thinking of G. Bachelard, and about what may have close didactic reference to the four elements. On the other hand, it will be necessary to show how this apparently absent phenomenology, but legitimate in the work of philosopher, exceeds the critical ironic praise of the tree and of the forest that sees, in the best case, the mark of a naive romantic Arcadia (cf. Le Walden de Thoreau), and in the worst, a form of new obscurantism exiting, in a “nouvel order écologique” (new ecological order), the potential mark of an éco-fascism. Under these conditions, a poetic that dialectizes the tree and the forest can prepare an ecology of foundation.

title: DEPRECATED: Influence of nationality on the interpretation of Ireland's tourism destination imagery
Creators: name: Murphy-Underhill, Catriona
Publisher: name: University of Plymouth
Year: 2005

description: This thesis investigates the influence of nationality on the interpretations of the tourism destination imagery of Ireland, drawing in particular on the views of tourists travelling from Britain. It involved an assessment of the influence (if any) of the nationality of the tourist and the nationality of the place on pre- and post-visit interpretations of Ireland's perceived and projected images, as well as an evaluation of the implications of such influences on Ireland's image as a tourist destination. By means of empirical research applied to the same sample of tourists travelling from Britain to Ireland via Shannon airport, the factors that contribute to the formation of respondents' perceived destination images were analysed, and the degree of image modification was assessed using pre- and postvisitation questionnaires. Meanwhile, the intended projected image of Ireland was determined by means of a semi-structured interview with a representative of Tourism Ireland, and a semiotic and content analysis of brochure material was undertaken to assess the projected and actual image projected. The results of the pre- and post-visit questionnaires demonstrated the need to use nationality and national identity together as both constructs have limitations when applied separately. It was also revealed that images measured over two points in time can vary through the influence of such factors as actual travel experiences with a destination, the nature and extent of information or promotional efforts that the respondents are exposed to, and changes in the economic and social environment. In addition, other factors were also found to mediate the perceived image of a destination and included the perceived national identity held by visitors, the nationality of passport held, levels of destination familiarity, the purpose of trip and travel intensity. Also, the results of the analysis of the intended image indicated that the intended image portrayed of Ireland was one of a natural environment populated with friendly people in an idealised landscape out of time. Collectively, the study identified a number of image gaps between the projected and perceived destination image and highlighted the need for an overall image modification strategy based on a combination of national identity and nationality as an important discriminating variable.
La fauna come inferno della psiche. Metamorfosi animali nelle interpretazioni lautréamontiane di Gaston Bachelard e Georges Bataille
Creators: name: Agnellini, Francesco
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Georges Bataille, Lautréamont, Animality, Metamorphosis, Evil

description: The article emphasizes the reading about the work of Lautréamont given by Gaston Bachelard and, in particular, the very important role that has in it the animal metamorphosis. In a second step, it would approach it through the analysis given by Georges Bataille in La Littérature et le Mal (Literature and Evil), but never fully expressed.

In the Lautréamont, Bachelard identifies as the formal cause of the Chants de Maldoror the vitalistic dynamism expressed by the rapid succession of images in the unit of animal metamorphosis. The procedure followed in the course of the analysis is similar to the one previously used in La Psychanalyse du feu (The psychoanalyse of the fire): to stress the infantile, subjective and poetic dimension that precedes any objective knowledge. Rather than an happy rêverie, Lautréamont makes figuratively evident an incendiary fantasy focused on the uprising, and expression of a complex of animal life which gives rise to a phenomenology of aggression; as if the call of the embers presented in La Psychanalyse du feu as an example of the most serene philosophy of the rest, had a necessary prelude in the hell of the psyche, graphically represented by the cruelty of animals that inhabit the Chants. Similarly, Georges Bataille sees in Lautreamont the founder of a literature that expressed herself as intensive communication, based on the knowledge of evil, far from everyday life, and near to the dark zones, unconscious, regulated by taboos, which heterology designates as the accursed share.

Therefore, the combination between the two authors is potentially really profitable, in the common vision of the ducassian work as a mental space animated by metamorphic images and expression of violent obsessions that translates the needs of animals and the desire of freedom of each person.

description: We present a non-perturbative quantization of general relativity coupled to dust and other matter fields. The dust provides a natural time variable, leading to a physical Hamiltonian with spatial diffeomorphism symmetry. The surprising feature is that the Hamiltonian is not a square root. This property, together with the kinematical structure of loop quantum gravity, provides a complete theory of quantum gravity, and puts in technical reach applications to cosmology, quantum gravitational collapse and Hawking radiation.

El dinamismo de la imaginación y la pulsión de volar: una revisitación de Bachelard
Creators: name: Burgos, Fernando
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Bachelard; experience of imagination; Alsino; the flows of imagining; drive of flying; persistence of psychical energy; imagining as becoming.

description: Among the most provocative propositions inaugurated by Bachelard’s work one cannot miss his reflection on the question of imagination as “a major force of human nature” (The Poetics of Space), anticipating thus the premise that the productivity of imagination does not reside—as was usually thought—in its capacity for creating images derived from reality but in “the faculty of forming images which would surpass reality” (Water and Dreams). In pursuing these ideas, Bachelard—apart from enriching the hermeneutical apparatus around the elucidation of literary works—was able to take his writing at the center of the becoming of the imagination as well as into the transcendental phenomena of the poetic vision. His understanding of the experience of imagination as a becoming would make possible the internalization of the flow of the imagining as an organic entity which could not possibly be ascribed to pragmatic fields of representation nor to chronological or linear dimensions. My essay reflects on the above referred principles which are essential to Bachelard’s construction of his poetics of imagination. Additionally, I contextualize these ideas with an analyses of the imaginative processes found in Pedro Prado’s work Alsino, a poetic novel that can be situated in the antipodes of rationality since its drive for the construct of the ascensional pertain to both the realm of the oneiric, and the plane of an enduring psychical energy.

description: This thesis analyses the effects of regulatory heterogeneity on trade flows and policymaking. To this aim, developing new indicators and methodological techniques is key and constitutes the main contribution of the four chapters. The first chapter addresses the question of regulatory heterogeneity measurement by constructing new indicators of NTMs and presenting stylized facts. The second one disentangles the drivers behind these regulatory heterogeneity indicators analyzing whether global value chains are already influencing these differences. The third chapter focuses on regulatory heterogeneity in the context of services trade and bridges the gravity model with the uncertainty in trade policy literature. The fourth and last chapter goes beyond particular aspects (i.e. regulatory heterogeneity) or sectors (services) to understand the impact of trade agreements with a more comprehensive approach. It analyzes the direct and third-country heterogeneous effects of trade agreements at the country pair level. In summary, this thesis provides a deeper understanding of regulatory heterogeneity providing novel NTMs indicators data and methodology to assess its heterogeneous effects on trade. Results inform key policymaking decisions such as NTMs that are more relevant to trade, the implications of GVCs in NTM, the relevance of avoiding uncertainty in services trade or a methodology to analyze when an agreement can be beneficial for its members, and how it will affect other countries.
The ethical image in a topological perspective: the poetics of Gaston Bachelard
Creators: name: Huang, Kuan-Min
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: being-there, well-being, world, survival, verticality, place

description: In the poetics of Gaston Bachelard, the natural images, especially the four elements (fire, water, air, earth), occupy the eminent place for literary imagination. Under this main frame, this paper tries to present the relation of ethics and aesthetics in focusing on the ethical image as a synthetic concept. It also argues that the poetic imagination in Bachelard presupposes a metaphysical base managing the being, the force, the will, and the action. There is a dynamic structure in this metaphysics of imagination. Notwithstanding the usual separation of different spheres in philosophy, Bachelard urges a primary fusion in the cosmic scale, i.e. the world and the human are communicative and correspondent.

Taking these principles into consideration, this paper explores the topological dimension in those poetic images of elements and space. The ontological sense of being-there is evaluated by the dynamic function of “there” in restoring its ethical meaning. Likewise, the terms “in front of the fire”, “before the water”, “in the water” are given the topological accents. The verticality indicating the dynamic function of the flight, of the falling, and of standing upright is topologically effective. In accordance to the verticality, the concept of survival contains an effect of surpassing the existential conditions, the prefix “sur-“ means that tentative of the higher degree. In sum, the cosmicity as the very place of ethical and ontological unification reveals Bachelard’s concern on the imaginative transformation of the personality, the appropriation in the cosmos.

description: Next-generation sequencing techniques have facilitated a large scale analysis of human genetic variation. Despite the advances in sequencing speeds, the computational discovery of structural variants is not yet standard. It is likely that many variants have remained undiscovered in most sequenced individuals. Here we present a novel internal segment size based approach, which organizes all, including also concordant reads into a read alignment graph where max-cliques represent maximal contradiction-free groups of alignments. A specifically engineered algorithm then enumerates all max-cliques and statistically evaluates them for their potential to reflect insertions or deletions (indels). For the first time in the literature, we compare a large range of state-of-the-art approaches using simulated Illumina reads from a fully annotated genome and present various relevant performance statistics. We achieve superior performance rates in particular on indels of sizes 20--100, which have been exposed as a current major challenge in the SV discovery literature and where prior insert size based approaches have limitations. In that size range, we outperform even split read aligners. We achieve good results also on real data where we make a substantial amount of correct predictions as the only tool, which complement the predictions of split-read aligners.

“Dérives du poème”. La poétique dans l’oeuvre de Gaston Bachelard et le travail critique de Claude Esteban
Creators: name: Bagdasarova, Satenik
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Bachelard, Esteban, word, poetics, myth, philosophy

description: Drawing on Claude Esteban’s essay “Dérives du poème”, this article offers a critical analysis of the conception of language underpinning the investment of the poetic act according to Bachelard. Published in Critique de la raison poétique in 1978 and typifying a 1980s critical approach, Esteban’s essay shows how Bachelard maintains and upholds the primacy of philosophy over poetics while at the same time claiming to surmount it. Through the prelinguistic union of words and things, and his investment of discourse in the word, Bachelard effectively reinforced the involvement of poetics in metaphysics, whereas his aim had been to disassociate the one from the other. In demonstrating the invalidity of conceiving the word as a category and model of speech – a move which leads, in Bachelard’s conception, to the annihilation of the subject’s empirical activity in language, to the advantage of Being – Claude Esteban highlights the necessity of interaction between poetics and linguistics. His questioning of those linguistic categories taken for granted by Bachelard aims in particular at the disassociation of poetics from myth, and at a corresponding move towards anthropology. This in turn allows us to reflect on the historic continuity of literary works and their capacity to shift social values.

Bachelard-Flocon, Paysages. Il mouvement – Forza, Provocazione, Volontà tra éléments e poésie
Creators: name: Chiore, Valeria
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Engraving, Movement, Flocon, Creative imagination, Materiality, Ontology

description: “Le graveur est voué au mouvement” writes Bachelard, commenting in the sign of movement, the fifteen tables of the engraver Albert Flocon, in a work composed by four hands in 1950, along the thin threshold that unites and separates art and philosophy, thematizing the movement – main principle for the psyche, imagination and dream – such as strength, creation and will.

Particular thamatization, that if has amazing wealth of content, referring to the notions of  “will to power”, “creative imagination”, “provocation and promotion of materiality”, also acts as a bridge between two different formulations of the movement: on the one hand the elementalist movement, tied to air, water, earth and fire – Empedocle’s rizomata, as always, Aristotelian, beds as natural roots of natural feelings (this will be the case of Novalis, Poe, Nietzsche and Goethe, poets of air, water, fire, and earth, lords of the Tetravalent Doctrine of Poetic Temperaments); on the other hand a movement that, dropped from the material substrate, is a direct expression of the poetic word (this will be the case of flame or light in Novalis, or even the poetic du Phénix that cross, soaring, La Flamme d'une Chandelle or Fragments d'une Poétique du Feu).

Complex process, which, engaging psyche, imagination and art at first on the elements (Material Imagination of the Elements) – passing through the psychologistic relief of Freud, Jung and Desoille – places the movement in the point of articulation between two different ontologies: the ontology of elements and the ontology of poetry.

description: Synchronization, the emergence of spontaneous order in coupled systems, is of fundamental importance in both physical and biological systems. We demonstrate the synchronization of two dissimilar silicon nitride micromechanical oscillators, that are spaced apart by a few hundred nanometers and are coupled through optical radiation field. The tunability of the optical coupling between the oscillators enables one to externally control the dynamics and switch between coupled and individual oscillation states. These results pave a path towards reconfigurable massive synchronized oscillator networks.
CMB at 2x2 order: the dissipation of primordial acoustic waves and the observable part of the associated energy release

description: Silk damping of primordial small-scale perturbations in the photon-baryon fluid due to diffusion of photons inevitably creates spectral distortions in the CMB. With the proposed CMB experiment PIXIE it might become possible to measure these distortions and thereby constrain the primordial power spectrum at comoving wavenumbers 50 Mpc^{-1} < k < 10^4 Mpc^{-1}. Since primordial fluctuations in the CMB on these scales are completely erased by Silk damping, these distortions may provide the only way to shed light on otherwise unobservable aspects of inflationary physics. A consistent treatment of the primordial dissipation problem requires going to second order in perturbation theory, while thermalization of these distortions necessitates consideration of second order in Compton scattering energy transfer. Here we give a full 2x2 treatment for the creation and evolution of spectral distortions due to the acoustic dissipation process, consistently including the effect of polarization and photon mixing in the free streaming regime. We show that 1/3 of the total energy (9/4 larger than previous estimates) stored in small-scale temperature perturbations imprints observable spectral distortions, while the remaining 2/3 only raises the average CMB temperature, an effect that is unobservable. At high redshift dissipation is mainly mediated through the quadrupole anisotropies, while after recombination peculiar motions are most important. During recombination the damping of the higher multipoles is also significant. We compute the average distortion for several examples using CosmoTherm, analyzing their dependence on parameters of the primordial power spectrum. For one of the best fit WMAP7 cosmologies, with n_S=1.027 and n_run=-0.034, the cooling of baryonic matter practically compensates the heating from acoustic dissipation in the mu-era. (abridged)

description: We describe a framework in which is possible to develop and implement algorithms for the approximation of invariant measures of dynamical systems with a given bound on the error of the approximation. Our approach is based on a general statement on the approximation of fixed points for operators between normed vector spaces, allowing an explicit estimation of the error. We show the flexibility of our approach by applying it to piecewise expanding maps and to maps with indifferent fixed points. We show how the required estimations can be implemented to compute invariant densities up to a given error in the $L^{1}$ or $L^\infty $ distance. We also show how to use this to compute an estimation with certified error for the entropy of those systems. We show how several related computational and numerical issues can be solved to obtain working implementations, and experimental results on some one dimensional maps.

Consumption city : precarious labour and capital in Vancouver, British Columbia
Creators: name: Siemiatycki, Elliot
Publisher: name: University of British Columbia
Year: 2013

description: Vancouver is increasingly being recognized as a model of urban development in the 21st century. While much of the attention paid to Vancouver has focused on ‘Vancouverism’ as an urban planning and design approach that encourages high-density, amenity-rich, mixed-use development to reenergize urban cores, this dissertation examines the exceptional economic development trajectory underlying Metro Vancouver’s urban transformation since the early 1980s. The central claim in this research is that changes to the built form of the city over the past three decades represent a fundamental shift in the orientation of the local economy away from export-oriented resource activity and business services towards local consumption in real estate and tourism which is driven by inward international investment and immigration. The single most important outcome of this largely unplanned shift in urban economic development has been the unprecedented increases in local housing prices. Instead of a healthy ‘diversified’ economy, this reorientation of Vancouver as a consumption city has created a dysfunctional ‘hybrid’ economy characterized by significant job losses in key local economic sectors, below average levels of productivity and exports, and relatively low incomes. Through a set of comparative sectoral case studies exploring food and beverage services, legal services and digital media services, this dissertation seeks to understand what impact the rise of Vancouver as a consumption city has had on local workers and firms. This research complicates a variety of conceptual frameworks used by human geographers such as precarious employment, global and creative cities, firm competitiveness, and entrepreneurial governance. Above all, the many paradoxes of Vancouver’s contemporary economic development trajectory are exposed in the words of local workers, firms, commentators and industry experts: Vancouver is simultaneously the most livable and unaffordable city in the world; Vancouver is a leading creative city in which creative firms and workers alike struggle under conditions of precariousness; Vancouver is mythologized as a healthy, sustainable, lifestyle city while these very qualities often must be sacrificed by working Vancouver residents. Tracing the underlying story and challenges of Vancouver’s emergence as a global consumption city provides important insights into 21st century urban development.

description: We theoretically study slow collisions of NH$_3$ molecules with He atoms, where we focus in particular on the observation of scattering resonances. We calculate state-to-state integral and differential cross sections for collision energies ranging from 10${}^{-4}$ cm$^{-1}$ to 130 cm$^{-1}$, using fully converged quantum close-coupling calculations. To describe the interaction between the NH${}_3$ molecules and the He atoms, we present a four-dimensional potential energy surface, based on an accurate fit of 4180 {\it ab initio} points. Prior to collision, we consider the ammonia molecules to be in their antisymmetric umbrella state with angular momentum $j=1$ and projection $k=1$, which is a suitable state for Stark deceleration. We find pronounced shape and Feshbach resonances, especially for inelastic collisions into the symmetric umbrella state with $j=k=1$. We analyze the observed resonant structures in detail by looking at scattering wavefunctions, phase shifts, and lifetimes. Finally, we discuss the prospects for observing the predicted scattering resonances in future crossed molecular beam experiments with a Stark-decelerated NH$_3$ beam.

description: We present an algorithm for the integrand-level reduction of multi-loop amplitudes of renormalizable field theories, based on computational algebraic geometry. This algorithm uses (1) the Gröbner basis method to determine the basis for integrand-level reduction, (2) the primary decomposition of an ideal to classify all inequivalent solutions of unitarity cuts. The resulting basis and cut solutions can be used to reconstruct the integrand from unitarity cuts, via polynomial fitting techniques. The basis determination part of the algorithm has been implemented in the Mathematica package, BasisDet. The primary decomposition part can be readily carried out by algebraic geometry softwares, with the output of the package BasisDet. The algorithm works in both D=4 and $D=4-2ε$ dimensions, and we present some two and three-loop examples of applications of this algorithm.

description: We use deep Chandra imaging and an extensive optical spectroscopy campaign on the Keck 10-m telescopes to study the properties of X-ray point sources in five large-scale structures at redshifts of z ~ 0.7-0.9. We first study X-ray point sources using the statistical measure of cumulative source counts, finding that the measured overdensities are consistent with previous results, but we recommend caution in overestimating the precision of the technique. Optical spectroscopy of objects matched to X-ray point sources confirms a total of 27 AGN within the five structures, and we find that their host galaxies tend to be located away from dense cluster cores. More than 36% of host galaxies are located in the `green valley', which suggests they are a transitional population. Based on analysis of OII and Hd line strengths, the average spectral properties of the AGN host galaxies in all structures indicate either on-going star formation or a starburst within ~ 1 Gyr, and the host galaxies are younger than the average galaxy in the parent population. These results indicate a clear connection between starburst and nuclear activity. We use composite spectra of the spectroscopically confirmed members in each structure to separate them based on a measure of the overall evolutionary state of their constituent galaxies. We define structures as having more evolved populations if their average galaxy has lower EW(OII) and EW(Hd). The AGN in the more evolved structures have lower rest-frame 0.5-8 keV X-ray luminosities (all below 10^43.3 erg s^-1) and longer times since a starburst than those in the less evolved structures, suggesting that the peak of both star formation and AGN activity has occurred at earlier times. With the wide range of evolutionary states and timeframes in the structures, we use our results to analyze the evolution of X-ray AGN and evaluate potential triggering mechanisms.

description: Facial emotional expressions are crucial in face-to-face social interactions, and recent findings have highlighted their interactive nature. However, the underlying neural mechanisms remain unclear. This electroencephalography study investigated whether the interactive exchange of facial expressions modulates socio-emotional processing. Participants (N = 41) displayed a facial emotional expression (angry, neutral, or happy) toward a virtual agent, and the agent then responded with a further emotional expression (angry or happy) or remained neutral (control condition). We assessed subjective experience (valence, arousal), facial EMG (Zygomaticus, Corrugator), and event-related potentials (EPN, LPP) elicited by the agent’s response. Replicating previous findings, we found that an agent’s happy facial expression was experienced as more pleasant and elicited increased Zygomaticus activity when participants had initiated the interaction with a happy compared to an angry expression. At the neural level, angry expressions resulted in a greater LPP than happy expressions, but only when participants directed an angry or happy, but not a neutral, expression at the agent. These findings suggest that sending an emotional expression increases salience and enhances the processing of received emotional expressions, indicating that an interactive setting alters brain responses to social stimuli.

description: We forecast the abilities of the Atacama Large Millimeter/submillimeter Array (ALMA) and the Square Kilometer Array (SKA) to detect CO and HI emission lines in galaxies at redshift z=3. A particular focus is set on Milky Way (MW) progenitors at z=3 for their detection within 24 h constitutes a key science goal of ALMA. The analysis relies on a semi-analytic model, which permits the construction of a MW progenitor sample by backtracking the cosmic history of all simulated present-day galaxies similar to the real MW. Results: (i) ALMA can best observe a MW at z=3 by looking at CO(3-2) emission. The probability of detecting a random model MW at 3-sigma in 24 h using 75 km/s channels is roughly 50%, and these odds can be increased by co-adding the CO(3-2) and CO(4-3) lines. These lines fall into ALMA band 3, which therefore represents the optimal choice towards MW detections at z=3. (ii) Higher CO transitions contained in the ALMA bands geq6 will be invisible, unless the considered MW progenitor coincidentally hosts a major starburst or an active black hole. (iii) The high-frequency array of SKA, fitted with 28.8 GHz receivers, would be a powerful instrument for observing CO(1-0) at z=3, able to detect nearly all simulated MWs in 24 h. (iv) HI detections in MWs at z=3 using the low-frequency array of SKA will be impossible in any reasonable observing time. (v) SKA will nonetheless be a supreme ha survey instrument through its enormous instantaneous field-of-view (FoV). A one year pointed HI survey with an assumed FoV of 410 sqdeg would reveal at least 10^5 galaxies at z=2.95-3.05. (vi) If the positions and redshifts of those galaxies are known from an optical/infrared spectroscopic survey, stacking allows the detection of HI at z=3 in less than 24 h.

description: We investigate scattering through chaotic ballistic quantum dots in the Coulomb blockade regime. Focusing on the scattering phase, we show that large universal sequences emerge in the short wavelength limit, where phase lapses of $π$ systematically occur between two consecutive resonances. Our results are corroborated by numerics and are in qualitative agreement with existing experiments.

title: DEPRECATED: The influence of nitrification in determining the supply, distribution and fate of nitrogen in grassland soils

description: The microbiology of nitrification has been extensively studied, but the ecology and environmental impact of the process has received less attention. The reason for this has more to do with the difficulties of conducting field experiments to examine the links with other processes which cause losses of nitrogen, than a failure to appreciate its importance in agricultural systems. This project was designed to overcome some of the limitations of existing field techniques to enable simultaneous measurements of nitrification and the major processes of N supply (mineralization) and N loss (denitrification and leaching) to be examined. The study proceeded in three distinct phases: firstly, soils with contrasting N management histories were examined, using laboratory assays for potential activities. Clear differences which resulted from higher N inputs were established, with correspondingly higher nitrifying activities. For example, in a fertilized soil, ammonia-oxidizers produced 48.4 compared with 1.3 nM N02 gˉ¹ soil hˉ¹ in an unfertilized soil. Potential nitrite-oxidizing rates were 93.4 and 62.5 nM gˉ¹ hˉ¹ respectively. Assays of enzyme kinetics, therefore confirmed the higher nitrifying activity in the fertilized soil, but demonstrated a lower affinity of the enzyme for N02- substrate, with K, values of 436 and 310 µM N02 -N, respectively. Nitrifying rates in soils from grass-clover swards were intermediate between the fertilized and unfertilized soils. Secondly, a new field incubation technique was developed and used to obtain actual rates by concurrent measurements of the major N cycling processes. A strong correlation was established between nitrification and denitrification (r² = 0. 98). The measurements were verified by comparison with other independent methods. Net rates of nitrification in the same soil type ranged from 0.55 - 1.17 kg N haˉ¹ dˉ¹ , with the highest rates in the fertilized soil. Over 70% of the mineralized N was nitrified, of which 80% was subsequently lost (i.e. either denitrified or leached). Thirdly, the practical implications of these findings were examined in greater detail using 15N labelling techniques which enabled process rates (net and gross) to be established in a model of the N cycle. When nitrification was inhibited, there were no significant differences between gross or net mineralization rates in the soils from the three swards, which indicated that N-immobilization could be directly influenced by the level of nitrifying activity in these soils. The influence of nitrification in determining the pathways of N loss from grassland soils was quantified in this study. From a detailed investigation of the processes involved in N cycling, it was deduced that nitrification was also one of the major factors in determining the outcome of competition for inorganic N between plant and microbial biomasses.

description: The present collider data put severe constraints on any type of new strongly-interacting particle coupling to the Higgs boson. We analyze the phenomenological limits on exotic quarks belonging to non-triplet SU(3)_C representations and their implications on Higgs searches. The discovery of the Standard Model Higgs, in the experimentally allowed mass range, would exclude the presence of exotic quarks coupling to it. Thus, such QCD particles could only exist provided that their masses do not originate in the SM Higgs mechanism.

description: The electronic and electrical properties of crystalline organic semiconductors, such as the dispersions of the electronic bands and the dependence of charge-carrier mobility on temperature, are greatly impacted by the nonlocal electron-phonon interactions associated with intermolecular lattice vibrations. Here, we present a theoretical description that underlines that these properties vary differently as a function of the symmetry of the nonlocal electron-phonon coupling mechanism. The electron-phonon coupling patterns in real space are seen to have a direct and significant impact on the interactions in reciprocal space. Our findings demonstrate the importance of aspects that are usually missing in current transport models. Importantly, an adequate description of the electronic and charge-transport properties of organic semiconductors requires that the models take into account both antisymmetric and symmetric contributions to the nonlocal electron-phonon coupling mechanism.
