England Calling: A Narratological Exploration of Martin Amis’s 'London Fields'
No full textThis paper will explore connections between fictional narrative methodology and contemporary conceptions of Englishness by applying aspects of Gerald Prince’s (2005) conceptions of a ‘postcolonial narratology’ to Martin Amis’s “London Fields” (1989). Amis has commented that ‘it’s almost an act of will on my part trying not to be an English writer’. However, this paper will suggest that the novel under consideration here exhibits methodological tendencies which have their roots in a protracted engagement with problematic notions of English identity (principally, instability and disengagement) and that postcolonial approaches to narrative technique can lead to very interesting results, even when applied to the work of writers not typically identified with such constituencies. The central point of investigation will be the novel’s exhibition of metafictional tendencies. In “London Fields”, Amis narrates via an authorial surrogate, Samson Young, who purports to be the author of the text, yet becomes implicated in the events of the novel to the point where his actions, rather than his imagination, determine its outcome. It is interesting also in this connection that the novel is voiced by an ‘outsider’ to England, an American.
Prince is intrigued by the possibility that a postcolonial narrative discourse might emerge ‘free of any narratorial introduction, mediation, or patronage.’ He also points to the significance of narratological features such as hybridity, migrancy, otherness, fragmentation, diversity and power relations. Amis’s novel exhibits all of these features, and takes the ambition of authorial invisibility to a paradoxical extreme. Voices, characters, reliability and even actantial events are brusquely ‘disowned’ by the author, resulting in a textual instability and uncertainty which, it will be demonstrated through close textual analysis, is intimately linked to England’s postcolonial condition
Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
Conclusion
No full textThis chapter reflects on the state of the field and assesses what the approaches represented in this volume collectively can achieve; the strengths, weaknesses, and potential of historical ecology and applied archaeology and the overlap between them. Definitions drawing on the discourse developed in the volume of both concepts are offered, and the opportunities and challenges of inter- and transdisciplinary research are summarized. The future of a usable past is discussed by contextualizing volume chapters in relation to the Sustainable Development Goals. It is suggested that research in the fields of historical ecology and applied archaeology follows three main approaches: (1) generating case studies of the past as difference, elucidating phenomena in the past that may suggest alternative possibilities to those observed in the present; (2) informing phenomena observed in the present by generating analogous case studies from the past; and (3) detailing the dynamics of long-term human–environmental processes.</p
Wet and gassy zones in a municipal landfill from P- and S-wave velocity fields
No full textThe knowledge of the distribution of leachate and gas in a municipal landfill is of vital importance to the landfill operators performing improved landfill treatments and for environmental protection and efficient biogas extraction. We have explored the potential of using the velocity fields of seismic S- and P-waves to delineate the wet and gassy (relatively dry, gas/air-filled) zones inside a landfill.We have analyzed shallow S- and P-wave reflection data and seismic surface-wave data acquired at a very heterogeneous landfill site, where biogas was extracted. A joint interpretation of the independently estimated velocity fields from these various approaches has allowed us to localize anomalously low- and high-velocity zones in the landfill. From the complementary information provided by P- and S-wave velocity fields, we have inferred the leachate-bearing wet zones and the gassy zones inside the landfill. Independent measurements of gas flow and mechanical tip resistance to waste deformation validate our seismic interpretations
Large P\'{o}lya groups in simplest cubic fields and consecutive bi-qaudratic fields
No full textThe P\'{o}lya group of an algebraic number field is the subgroup generated by
the ideal classes of the products of prime ideals of equal norm inside the
ideal class group. Inspired by a recent work on consecutive quadratic fields
with large class numbers by Cherubini et al., we extend the notion of {\it
consecutiveness} of number fields to certain parametric families of cyclic
cubic fields and bi-quadratic fields and address the question of the existence
of infinitely many such consecutive fields with large P\'{o}lya groups. This
extends a recent result of the second author and Saikia for totally real
bi-quadratic fields.Comment: 7 - epsilon pages. Comments are welcom
Influence of Local Magnetic Fields on P-Doped Si Floating Zone Melting Crystal Growth in Microgravity
No full textA two-dimensional axisymmetric numerical model is presented to study the influence of local magnetic fields on P-doped Si floating zone melting crystal growth in microgravity. The model is developed based on the finite difference method in a boundary-fitted curvilinear coordinate system. Extensive numerical simulations are carried out, and parameters studied include the curved growth interface shape and the magnetic field configurations. Computed results show that the local magnetic field is more effective in reducing the impurity concentration nonuniformity at the growth interface in comparison with the longitudinal magnetic field. Moreover, the curved growth interface causes more serious impurity concentration nonuniformity at the growth interface than the case with a planar growth interface
Modular symbols over number fields
No full textLet K be a number field, R its ring of integers. For some classes of fields, spaces of cusp forms of weight 2 for GL(2;K) have been computed using methods based on modular symbols. J.E. Cremona [9] began the programme of extending the classical methods over Q to the case of imaginary quadratic fields. This work was continued by some of his Ph.D. students [35, 6, 22], and results have been obtained for some imaginary quadratic fields with small class number. More recently, P. Gunnells and D. Yasaki [18] have developed related algorithms for real quadratic fields.
The aim of this thesis is to contribute to the extension of the modular symbols method, when possible developing algorithms and implementations for effective computations. Some parts of the theory are purely algebraic and can be extended to all number fields. We generalise the theory for cusps and Manin symbols; we also describe a generalisation of Atkin-Lehner involutions and study other normaliser elements. On the other hand, all previous explicit computations for the imaginary quadratic field case were done only for specific fields. In the last part of this thesis we begin work towards a general implementation of the techniques used in this case. In particular, we are able to compute a fundamental domain of the hyperbolic 3-space for any imaginary quadratic field.
Implementations of the algorithms described in this thesis have been written by the author in the open-source mathematics software Sage [31]
Disentangling inertial waves from eddy turbulence in a forced rotating turbulence experiment
No full textWe present a spatio-temporal analysis of a statistically stationary rotating turbulence experiment, aiming to extract a signature of inertial waves and to determine at what scales and frequencies they can be detected. This analysis is performed from two-point correlations of temporal Fourier transform of the velocity fields obtained from time-resolved stereoscopic particle image velocimetry measurements in the rotating frame. We quantify the degree of anisotropy of turbulence as a function of frequency and spatial scale normal to the rotation axis. We show that this space-time-dependent anisotropy is well described by the dispersion relation of linear inertial waves at large scale, while smaller scales are dominated by the nonlinear sweeping of the waves by the random motions at larger scales. This sweeping effect is dominated here by the low-frequency quasi-two-dimensional component of the turbulence, a prominent feature of our experiment which is not accounted for by the weak wave turbulence theory
