Alan Seeger: medievalism as an alternative ideology
No full textThe American poet Alan Seeger imagined the First World War as an opportunity to realize medieval values, which were embodied for him in Sir Philip Sidney. Sidney epitomized Seeger’s three ideals: “Love and Arms and Song,” which contrasted with the materialism and sophistication of modernity. His embrace of “Arms” and the desire for intense, authentic experience led Seeger, who was living in Paris in August 1914, to enlist in the French Foreign Legion, in which he served until his death in combat in July 1916. As an infantryman Seeger had extensive experience of the Western front. This concrete experience of the war, of the indignities of life in the trenched and the
dominance of technology, contrasted in significant ways with war as constructed in
Seeger’s medievalist imagination.
Seeger, however, reconciled this contradiction by seeing the war as part of the elemental Strife of nature. By this means, Seeger avoided the potentially unsettling consequences of confronting the profoundly modern nature of the war. Interpreting the war as a form of “Strife” and as an assertion of medieval values allowed Seeger to imagine himself and his comrades to be living outside the world of industrial capitalist modernity. Seeger shared with others involved in the war this medievalism and the belief that the war offered relief from the values of modernity, even if Seeger’s medievalism was more intense, more thoroughgoing, than was common. However, Seeger’s death as a result of wounds received from machine gun fire vividly displays the contradiction between his imagination and the reality of industrialized warfare.
The example of Seeger thus suggests that the American effort in the First World War was underwritten in part by an ideology through which a modern, industrialized war was embraced in terms derived from the imagined medieval past. Insofar as this is true medievalism functioned to provide an ideology that constructed, in the terminology of Raymond Williams, an alternative to the industrial capitalist modernity from which the war emerged, an alternative ideology that allowed the war to be imagined differently from what it was, but which posed no substantive challenge to the war’s social and economic realities

Large Scale Variational Inference and Experimental Design for Sparse Generalized Linear Models
No full textSparsity is a fundamental concept of modern statistics, and often the only general principle available at the moment to address novel learning applications with many more variables than observations. While much progress has been made recently in the theoretical understanding and algorithmics of sparse point estimation, higher-order problems such as covariance estimation or optimal data acquisition are seldomly addressed for sparsity-favouring models, and there are virtually no algorithms for large scale applications of these. We provide novel approximate Bayesian inference algorithms for sparse generalized linear models, that can be used with hundred thousands of variables, and run orders of magnitude faster than previous algorithms in domains where either apply. By analyzing our methods and establishing some novel convexity results, we settle a long-standing open question about variational Bayesian inference for continuous variable models: the Gaussian lower bound relaxation, which has been used previously for a range of models, is proved to be a convex optimization problem, if and only if the posterior mode is found by convex programming. Our algorithms reduce to the same computational primitives than commonly used sparse estimation methods do, but require Gaussian marginal variance estimation as well. We show how the Lanczos algorithm from numerical mathematics can be employed to compute the latter.
We are interested in Bayesian experimental design here (which is mainly driven by efficient approximate inference), a powerful framework for optimizing measurement architectures of complex signals, such as natural images. Designs optimized by our Bayesian framework strongly outperform choices advocated by compressed sensing theory, and with our novel algorithms, we can scale it up to full-size images. Immediate applications of our method lie in digital photography and medical imaging.
We have applied our framework to problems of magnetic resonance imaging design and reconstruction, and part of this work appeared at a conference (Seeger et al., 2008). The present paper describes our methods in much greater generality, and most of the theory is novel. Experiments and evaluations will be given in a later paper

FEM Analysis Applied to OT Bridge Abutment with Seeger Retention System
No full textObjective The purpose of this investigation is to highlight the technical components of a new kind of screw-retained dental implant prosthesis. The hypothesis is whether the OT Bridge (Rhein 83 S.R.L.; Bologna, Italy) system could be applied without secondary screw in the all-on-four retention system, thanks to the presence of an internal seeger. Materials and Methods By using engineering device such as finite element method (FEM) and von Mises investigation, it has been studied how the fixed prosthodontics for full-arch retention can be influenced by the presence of the screw for stabilizing it. Results In a dental implant, one model with four different configurations of the full-arch prosthesis retainer and the seeger has been investigated and then examined in contrast with or without the passant screw for locking the system. The experiments of this virtual study highlighted different features and mechanical behaviors of prosthodontic attachments. Conclusion The first two configurations, respectively those in which there are four and three connection screws, are safe and predictable. Therefore, the presence of the seeger significantly improves the stability and the retention of the whole prosthesis
Supported Lipid Bilayers on Mica and Silicon Oxide: Comparison of the Main Phase Transition Behavior
No full textThe usual biophysical approach to the study of biological membranes is that of turtling to model systems. From these models, general physical principles ruling the lateral membrane structure can be obtained. A promising model system is the supported lipid bilayer (SLB) which could foresee the simultaneous investigation of the structure and physical properties of lipid bilayers reconstituted with membrane proteins. A complete exploitation of the model system to retrieve biologically relevant information requires an in-depth knowledge of the possible effect that experimental parameters could have on the behavior of the SLB. Here we used atomic force microscopy (AFM) to study the effect of different types of substrates on the behavior of SLBs as far as their main phase transition is concerned. We found that different substrates (mica and silicon oxide) can affect in dissimilar ways the interleaflet coupling of the bilayer, which might represent a sort of lipid signaling allowing communication between receptors on the extracellular leaflet and cytoplasmic components. By decreasing the interaction between the SLB and the substrate the interleaflet coupling is preserved independently of the bilayer preparation strategy. Moreover, we investigated by time-lapse AFM an isothermal phase transition induced by a pH change on a SLB. We established that the presence of a pH gradient across the bilayer can weaken the strength of the interleaflet coupling which is present in symmetrical pH conditions
Dynamic Force Spectroscopy on Supported Lipid Bilayers: Effect ofTemperature and Sample Preparation
No full textBiological membranes are constantly exposed to forces. The stress-strain relation in membranes determines thebehavior of many integral membrane proteins or other membrane related-proteins that show a mechanosensitive behavior. Here, we studied by force spectroscopy the behavior of supported lipid bilayers (SLBs) subjected to forces perpendicular to their plane. We measured the lipid bilayer mechanical properties and the force required for the punch-through event characteristic of atomic force spectroscopy on SLBs as a function of the interleaflet coupling. We found that for an uncoupled bilayer, the overall tip penetration occurs sequentially through the two leaflets, giving rise to two penetration events. In the case of a bilayer with coupled leaflets, penetration of the atomic force microscope tip always occurred in a single step. Considering the dependence of the jump-through force value on the tip speed, we also studied the process in the context of dynamic force spectroscopy (DFS). We performed DFS experiments by changing the temperature and cantilever spring constant, and analyzed the resultsin the context of the developed theories for DFS. We found that experiments performed at different temperatures and withdifferent cantilever spring constants enabled a more effective comparison of experimental data with theory in comparisonwith previously published data
