‘The Incarnate Now’: D.H. Lawrence, the New York School, and the Poetry of the Present and 'Things to Come'
This thesis consists of a critical study, “The Incarnate Now’: D. H. Lawrence, the New York School, and the Poetry of the Present’, followed by a collection of poetry, Things to Come. The critical study explores the legacy of D. H. Lawrence’s thinking about American poetry and the poetics of the present moment on the writing of the postwar period. Chapter I places Lawrence’s interest in America in context, introducing connections between his writing and the work of Walter Pater, Walt Whitman and Ralph Waldo Emerson; the chapter examines Lawrence’s own poetry in detail, drawing particularly on an important essay, ‘The Poetry of the Present’. Chapter II explores the significance of spontaneity and the present moment in postwar American poetry, outlining the emergence of a new set of cultural and aesthetic priorities and offering detailed readings (chiefly) of the poetry of Frank O’Hara and James Schuyler. Chapter III turns to the writing of John Ashbery, presenting a detailed examination of his poetry and its fulfillment of the ideas outlined in the previous chapters, focusing in particular on the poet’s temporal experiments and their impacts on the poem/reader. Overall, this study aims to emphasise the value of D. H. Lawrence to the poets of the New York School, offering his thinking as a new way to appreciate their various accomplishments
Deep Dive into NTP Pool's Popularity and Mapping
Time synchronization is of paramount importance on the Internet, with the Network Time Protocol (NTP) serving as the primary synchronization protocol. The NTP Pool, a volunteer-driven initiative launched two decades ago, facilitates connections between clients and NTP servers. Our analysis of root DNS queries reveals that the NTP Pool has consistently been the most popular time service. We further investigate the DNS component (GeoDNS) of the NTP Pool, which is responsible for mapping clients to servers. Our findings indicate that the current algorithm is heavily skewed, leading to the emergence of time monopolies for entire countries. For instance, clients in the US are served by 551 NTP servers, while clients in Cameroon and Nigeria are served by only one and two servers, respectively, out of the 4k+ servers available in the NTP Pool. We examine the underlying assumption behind GeoDNS for these mappings and discover that time servers located far away can still provide accurate clock time information to clients. We have shared our findings with the NTP Pool operators, who acknowledge them and plan to revise their algorithm to enhance security.</p
Wilkes Station Glaciology, 1958.
Submitted to the U.S. National Committee for the IGY, National Academy of Sciences, in partial fulfillment of IGY Project Number 4.10 - NSF Grant No. Y/4.10/285.This report contains the major part of the glaciological data collected by the 1958 wintering-over party at Wilkes Station. In several cases the measurements reported here are a continuation of those of 1957, and no attempt has been made to duplicate basic information already published in the data report for that year (Cameron et al., 1959). In conformity with IGY procedure, these first reports have been limited to data and to the information necessary for their analysis. A preliminary summary of the glaciological work at Wilkes Station in 1957 and 1958 has been published in the Journal of Glaciology (Hollin and Cameron, 1961) and is recommended as an introduction to this report.National Science Foundation Grant No. Y/4.10/285
Results of the randomized, placebo controlled clopidogrel and acetylsalicylic acid in bypass surgery for peripheal arterial disease (CASPAR) trial
Producción CientíficaObjective: Dual antiplatelet therapy with clopidogrel plus acetylsalicylic acid (ASA) is superior to ASA alone in patients
with acute coronary syndromes and in those undergoing percutaneous coronary intervention. We sought to determine
whether clopidogrel plus ASA conferred benefit on limb outcomes over ASA alone in patients undergoing below-knee
bypass grafting.
Methods: Patients undergoing unilateral, below-knee bypass graft for atherosclerotic peripheral arterial disease (PAD)
were enrolled 2 to 4 days after surgery and were randomly assigned to clopidogrel 75 mg/day plus ASA 75 to 100
mg/day or placebo plus ASA 75 to 100 mg/day for 6 to 24 months. The primary efficacy endpoint was a composite of
index-graft occlusion or revascularization, above-ankle amputation of the affected limb, or death. The primary safety
endpoint was severe bleeding (Global Utilization of Streptokinase and Tissue plasminogen activator for Occluded
coronary arteries [GUSTO] classification).
Results: In the overall population, the primary endpoint occurred in 149 of 425 patients in the clopidogrel group vs 151
of 426 patients in the placebo (plus ASA) group (hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.78-1.23). In
a prespecified subgroup analysis, the primary endpoint was significantly reduced by clopidogrel in prosthetic graft
patients (HR, 0.65; 95% CI, 0.45-0.95; P .025) but not in venous graft patients (HR, 1.25; 95% CI, 0.94-1.67, not
significant [NS]). A significant statistical interaction between treatment effect and graft type was observed (Pinteraction
.008). Although total bleeds were more frequent with clopidogrel, there was no significant difference between the rates
of severe bleeding in the clopidogrel and placebo (plus ASA) groups (2.1% vs 1.2%).
Conclusion: The combination of clopidogrel plus ASA did not improve limb or systemic outcomes in the overall
population of PAD patients requiring below-knee bypass grafting. Subgroup analysis suggests that clopidogrel plus ASA
confers benefit in patients receiving prosthetic grafts without significantly increasing major bleeding risk
Multiyear Droughts and Pluvials over the Upper Colorado River Basin and Associated Circulations
This study analyzes spatial and temporal characteristics of multiyear droughts and pluvials over the southwestern United States with a focus on the upper Colorado River basin. The study uses two multiscalar moisture indices: standardized precipitation evapotranspiration index (SPEI) and standardized precipitation index (SPI) on a 36-month scale (SPEI36 and SPI36, respectively). The indices are calculated from monthly average precipitation and maximum and minimum temperatures from the Parameter-Elevation Regressions on Independent Slopes Model dataset for the period 1950–2012. The study examines the relationship between individual climate variables as well as large-scale atmospheric circulation features found in reanalysis output during drought and pluvial periods. The results indicate that SPEI36 and SPI36 show similar temporal and spatial patterns, but that the inclusion of temperatures in SPEI36 leads to more extreme magnitudes in SPEI36 than in SPI36. Analysis of large-scale atmospheric fields indicates an interplay between different fields that yields extremes over the study region. Widespread drought (pluvial) events are associated with enhanced positive (negative) 500-hPa geopotential height anomaly linked to subsidence (ascent) and negative (positive) moisture convergence and precipitable water anomalies. Considering the broader context of the conditions responsible for the occurrence of prolonged hydrologic anomalies provides water resource managers and other decision-makers with valuable understanding of these events. This perspective also offers evaluation opportunities for climate models
Variation in fold geometry in the Yuso basin, northern Spain: implications for the deformation regime
First generation structures in greywackes of the Yuso Group from the Cantabrian Mountains of northern Spain show a distinct variation in geometry with depth in a regional synclinal structure (Curavacas and Lechada synclines); they are easily distinguished from other deformation events. In the structurally uppermost level we find `flap folds'. Flap folds are recumbent structures with the inverted limb preserved. Below this level `cascade folds' are found. These structures have a vergence opposite to that of parasitic folds. The nomenclature adopted is from Harrison and Falcon. Characteristically, these structures have shallowly dipping axial surfaces, in agreement with the shallow dip of the axial plane (regional) cleavage. In the lowermost structural level, upright parasitic folds with a steep cleavage are present. The variation in fold geometry is accompanied by a general steepening of the regional cleavage with increasing depth. In the absence of overprinting relationships the F1 fold geometries are included in a single deformation event.The steepening of the cleavage with depth reflects the change in orientation of the maximum shortening direction from sub-vertical in the upper part of the syncline to sub-horizontal in the lower part. With increasing depth the deformation regime during F1 changed from bending to buckling. The deformation regime on the regional scale, however, is associated with basement subsidence and passive formation of the regional synclinal structure. Furthermore, the absence of a distinct microfabric for the different F1 folds indicates that on a small scale a similar deformation regime was present. We conclude, therefore, that the scale at which we study a structure only reflects the deformation regime at that particular scale. Consequently, the overall deformation regime cannot be determined from single outcrops or microstructural analysis alone.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26441/1/0000529.pd
In search of the authentic nation: landscape and national identity in Canada and Switzerland
While the study of nationalism and national identity has flourished in the last decade, little attention has been devoted to the conditions under which natural environments acquire significance in definitions of nationhood. This article examines the identity-forming role of landscape depictions in two polyethnic nation-states: Canada and Switzerland. Two types of geographical national identity are identified. The first – what we call the ‘nationalisation of nature’– portrays zarticular landscapes as expressions of national authenticity. The second pattern – what we refer to as the ‘naturalisation of the nation’– rests upon a notion of geographical determinism that depicts specific landscapes as forces capable of determining national identity. The authors offer two reasons why the second pattern came to prevail in the cases under consideration: (1) the affinity between wild landscape and the Romantic ideal of pure, rugged nature, and (2) a divergence between the nationalist ideal of ethnic homogeneity and the polyethnic composition of the two societies under consideration
Confusion after spine injury: cerebral fat embolism after traumatic rupture of a Tarlov cyst: Case report
<p>Abstract</p> <p>Background</p> <p>Acute low back pain is a very common symptom and reason for many medical consultations. In some unusual circumstances it could be linked to a rare aetiology.</p> <p>Case presentation</p> <p>We report a 70-year-old man with an 8-month history of left posterior thigh and leg pain who had sudden confusion after a fall from standing. It was due to cerebral fat embolism suspected by computed tomography scan, later confirmed by brain magnetic resonance imaging (MRI). A spinal MRI scan was then performed and revealed a sacral fracture which drained into an unknown perineurial cyst (Tarlov cyst). Under medical observation the patient fully recovered within three weeks.</p> <p>Conclusions</p> <p>Sacral perineurial cysts are rare, however they remain a potential cause of lumbosacral radiculopathy.</p
