Beyond Triton: Samuel R. Delany's Critical Utopianism and the Colliding Worlds in “We, in Some Strange Power's Employ, Move on a Rigorous Line”
Authors: Tabone Mark A. 
Published: October 2013

ABSTRACT
Samuel R. Delany is among a group of authors who revivified the utopian imagination in science fiction during the late 1960s and early 1970s. This article discusses Delany's novella “We, in Some Strange Power's Employ, Move on a Rigorous Line” (1968). It revisits scholarship on Delany and on utopia to offer theoretical and historical perspectives concerning how this text, which has been lauded by reviewers but overlooked by scholars, represents an early contribution to the then-nascent genre of the “critical utopia,” one that bears many of the genre's hallmarks and prefigures later works. “We, in Some Strange Power's Employ” narrates a mid-twenty-first-century clash between two fully articulated utopian visions. This article details how the tension between these diametrically opposed “worlds” foments critical scrutiny of both in order to gesture toward a utopian horizon beyond them. It also demonstrates how Delany's novella performs a critical utopian intervention in the cultural politics of its present. Through the “play of worlds” in the narrative's “possible future” Delany advances evenhanded critiques of both sides of the 1960s “culture war” while retaining the decade's utopian zeitgeist, a desire for an impossible “something else” beyond the culture/counterculture dichotomy.
Hippies and the Mystic Way: Dropping Out, Unitive Experiences, and Communal Utopianism
Authors: Shipley Morgan 
Published: October 2013

ABSTRACT
This article hopes to uncover the relationship among psychedelics, mystic interpretations, and hippie projects of communal utopianism. Specifically, it traces the evolution of dropping out as an ahistorical, mystical orientation dialectically emerging within the framework of liberal-capitalist modernity. This orientation results from a fissure within the constructs of modernity itself, unsettling the progressive pulse of modern practices, revealing spaces to simultaneously challenge institutional hierarchy or materialist consumerism while experimenting with alternative moments of unitive togetherness. To construct an investigation into hippie mysticism and communal utopianism, this article (1) engages the dystopic problem of modernity through the lens of 1960s social, political, and cultural theorists, specifically Herbert Marcuse, who influenced the intellectual landscape of countercultural responses and situates the utopic implications of dropping out; and (2) uncovers the mystical vision of a key hippie philosopher, Stephen Gaskin, whose communal utopianism continues to challenge the homogeneity of modern culture, offering a vision of absolute love, responsibility, and community. I argue that dropping out offered a distinct antimodern impulse derived from mystical prophecies and experiences of absolute togetherness that, potentially, presents a lens through which to critically engage the challenges of “modern” society, rescuing the intuitive sense “of all of us being one.”

Published: October 2013

AbstractWe present a new whole mantle P wave tomographic model GAP_P4. We used two data groups; short‐period data of more than 10 million picked‐up onset times and long‐period data of more than 20 thousand differential travel times measured by waveform cross correlation. Finite frequency kernels were calculated at the corresponding frequency bands for both long‐ and short‐period data. With respect to an earlier model GAP_P2, we find important improvements especially in the transition zone and uppermost lower mantle beneath the South China Sea and the southern Philippine Sea owing to broadband ocean bottom seismometers (BBOBSs) deployed in the western Pacific Ocean where station coverage is poor. This new model is different from a model in which the full data set is interpreted with classical ray theory. BBOBS observations should be more useful to sharpen images of subducted slabs than expected from simple raypath coverage arguments.

Methode der kontinuierlichen Variation: Verwendung von Job‐Plots zur Untersuchung molekularer Assoziationen in der metallorganischen Chemie
Authors: Renny Joseph S. , Tomasevich Laura L. , Tallmadge Evan H. , Collum David B. 
Published: October 2013

AbstractDieser Aufsatz beschreibt Anwendungen der Methode der kontinuierlichen Variation (MCV oder Job‐Plots) auf Fragen der metallorganischen Chemie. Die MCV bietet qualitative und quantitative Einblicke in die Stöchiometrien, die der Assoziation von m Molekülen A und n Molekülen B zur Bildung von AmBn zugrunde liegen. Auch komplexere Fälle von Metallclustern und Aggregaten sind beschreibbar. Job‐Plots, in denen Reaktionsgeschwindigkeiten verfolgt werden, liefern relative Stöchiometrien geschwindigkeitsbestimmender Übergangsstrukturen. In einer speziellen Variante werden von den Liganden oder dem Lösungsmittel abhängige Reaktionsgeschwindigkeiten in Grundzustands‐ und Übergangszustandsbeiträge aufgegliedert, was einen Einblick in die vollständige Reaktionskoordinate mithilfe eines einzigen Job‐Plots ermöglicht. Die Lücken in der Literatur werden aufgezeigt und besprochen.
Self‐assembled nanoblends of functional polystyrene and a reactive aramid: Morphological and thermomechanical profile
Authors: Kausar Ayesha , Zulfiqar Sonia , Sarwar Muhammad Ilyas 
Published: October 2013

ABSTRACTVarious blends composed of pure polystyrene (PS) and modified PS [amino‐functionalized polystyrene (PS–NH2)] were prepared with a new aromatic polyamide obtained through the polycondensation of 1,5‐diaminonaphthalene and 1,4‐phenylenediamine with isophthaloyl chloride. The variation in the morphological and thermophysical profiles in the two blend systems with aramid loading were investigated. The amine functionality introduced to PS enhanced its compatibility with the polyamide because of the formation of an aramid‐graft‐PS copolymer. The grafting, hydrogen bonding, and phenylene‐ring (π–π) stacking between the chains of the two components finally nurtured self‐assembled nanostructured blends. A strong compatibilizing effect was observed for the 50, 60, and 70 wt % aramid blends, where an exceptionally inimitable cocontinuous self‐assembled morphology was formed by PS–NH2/aramid. Significant developments in the morphology along with thermal and mechanical stability were observed for the reactive PS/aramid system. The most favorable mechanical and thermal data supported by the finest nanostructure were observed with 70 wt % polyamide addition. Future prospects may involve the formation of nanotemplates and nanostructured membranes. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2014,131, 39954.
Determination of chromium(III) in aqueous solution using CePO4:Tb3+ nanocrystals in a fluorescence resonance energy transfer system
Authors: Chen Hong‐Qi , Wu Yong , Zhang Yi‐Yan , Guan Ying‐Ying , Wang Lun 
Published: October 2013

ABSTRACTTrivalent chromium is an essential element required for normal carbohydrate, lipid and protein metabolism in humans and animals. This article describes an efficient fluorescence resonance energy transfer (FRET) system between CePO4:Tb3+ nanocrystals as the donor and chromium(III) as the acceptor. CePO4:Tb3+ nanocrystals were synthesized in aqueous solution, and characterized by transmission electron microscopy. Under optimum conditions, a linear calibration graph was obtained (R2 = 0.996). The linear range and detection limit of chromium(III) were 0.01–2.2 μM, and 9.1 nM, respectively. The proposed method had a wide linear range and proved to be very sensitive, rapid and simple. Moreover, the method was applied successfully to the determination of chromium(III) in synthetic samples and tap water. Copyright © 2013 John Wiley & Sons, Ltd.
Mushroom Hunting by Using Bioinformatics: Application of a Predictive Framework Facilitates the Selective Identification of Sesquiterpene Synthases in Basidiomycota

Published: October 2013

AbstractThe Basidiomycota fungi represent a diverse source of natural products, particularly the sesquiterpenoids. Recently, genome sequencing, genome mining, and the subsequent discovery of a suite of sesquiterpene synthases in Omphalotus olearius was described. A predictive framework was developed to facilitate the discovery of sesquiterpene synthases in Basidiomycota. Phylogenetic analyses indicated a conservation of both sequence and initial cyclization mechanisms used. Here, the first robust application of this predictive framework is reported. It was used to selectively identify sesquiterpene synthases that follow 1,6‐, 1,10‐, and 1,11‐cyclization mechanisms in the crust fungus Stereum hirsutum. The successful identification and characterization of a 1,6‐ and a 1,10‐cyclizing sesquiterpene synthase, as well as three 1,11‐cyclizing Δ6‐protoilludene synthases, is described. This study verifies the accuracy and utility of the predictive framework as a roadmap for the discovery of specific sesquiterpene synthases from Basidiomycota, and thus represents an important step forward in natural product discovery.

Published: October 2013

ObjectiveTo compare optical coherence tomography (OCT)‐derived plaque characteristics of coronary target lesions between diabetic patients with acute coronary syndrome (ACS) versus stable angina pectoris (SAP).BackgroundIn vivo assessment of plaque composition of coronary culprit lesions in a cardiovascular high‐risk population with diabetes mellitus is incompletely elucidated.Methods102 diabetic patients with coronary de novo lesions were enrolled and categorized into an ACS‐group (40 patients) and a SAP‐group (62 patients) according to their clinical presentation. Assessment of clinical data, angiographic, and OCT imaging including the analysis of plaque composition and lipid content of the target lesions were performed prior to percutaneous coronary intervention and compared between the two groups.ResultsPlaque characteristics of patients in the ACS‐group compared with the SAP‐group showed a higher incidence of lipid‐rich plaque [33 (82.5%) vs. 25 (40.3%)], thin‐capped fibroatheroma [29 (72.5%) vs. 10 (16.1%)], macrophage infiltration [32 (80.0%) vs. 21 (33.9%)], thrombus [23 (57.5%) vs. 2 (3.2%)], and plaque rupture [27 (67.5%) vs. 2 (3.2%)] (all P < 0.001). Moreover, there was a wider lipid arc (174.5 ± 33.8° vs. 122.9 ± 43.9°), a longer lipid plaque length (6.52 ± 2.04 mm vs. 3.73 ± 2.16 mm), a greater lipid volume index (1117.2 ± 349.9 vs. 504.8 ± 379.3), and a smaller minimal fibrous cap thickness (51.52 ± 9.14 µm vs. 80.33 ± 26.71 µm) within lipid‐rich lesions of ACS patients (all P < 0.001).ConclusionDiabetic patients with ACS exhibit more vulnerable plaque features in coronary culprit lesions compared with diabetic patients with SAP. This may provide rationale for a specific therapeutic strategy either by pharmacological plaque stabilization or coronary intervention in any lesion with vulnerable plaque morphology in patients with diabetes. © 2013 Wiley Periodicals, Inc.

Published: October 2013

ObjectivesTo define velocity criteria by ultrasonography for the detection of hemodynamically significant (>60%) renal artery in‐stent restenosis (ISR).BackgroundThe restenosis rate after renal artery stenting ranges between 10% and 20%. While duplex ultrasound criteria have been validated for native renal artery stenosis, there are no uniformly accepted validated criteria for stented renal arteries.MethodsVascular laboratory databases from two academic medical centers were retrospectively reviewed for patients who underwent renal artery stenting followed by duplex ultrasound evaluation and angiography (CT angiography or catheter angiography) as the gold standard.ResultsA cohort of 132 stented renal arteries that had angiographic comparisons was analyzed. Eighty‐eight renal arteries demonstrated 0–59% stenosis while 44 renal arteries revealed 60–99% stenosis by angiography. Both the mean peak systolic velocity (PSV) and the renal artery‐to‐aortic ratio (RAR) were significantly higher in renal arteries with 60–99% restenosis compared with those with 0–59% restenosis (PSV: 382 cm/sec ± 128 vs. 129 cm/sec ± 62, P<0.001; RAR: 5.3 ± 2.4 vs. 2.1 ± 1.0, P <0.001). The optimal PSV and RAR cutoffs for detecting 60–99% ISR were calculated by receiver operator characteristics curve analysis. The velocity criteria that are associated with these results will be discussed.ConclusionDuplex ultrasonography is an accurate technique to identify significant restenosis in stented renal arteries. The PSV and RAR cutoffs for detecting renal artery ISR are higher than those in native, unstented renal arteries. A normal duplex ultrasound after renal artery stenting virtually excludes significant restenosis. © 2013 Wiley Periodicals, Inc.

Published: October 2013

AbstractA new dinuclear RuII polypyridyl complex, [(bpy)2Ru(H2bpip)Ru(bpy)2]4+ (RuH2bpip, bpy=2,2‐bipyridine, H2bpip=2,6‐pyridyl(imidazo[4,5‐f][1,10]phenanthroline), was developed to act as a one‐ and two‐photon luminescent probe for biological Cu2+ detection. This RuII complex shows a significant two‐photon absorption cross section (400 GM) and displays a remarkable one‐ and two‐photon luminescence switch in the presence of Cu2+ ions. Importantly, RuH2bpip can selectively recognise Cu2+ in aqueous media in the presence of other abundant cellular cations (such as Na+, K+, Mg2+, and Ca2+), trace metal ions in organisms (such as Zn2+, Ag+, Fe3+, Fe2+, Ni2+, Mn2+, and Co2+), prevalent toxic metal ions in the environment (such as Cd2+, Hg2+, and Cr3+), and amino acids, with high sensitivity (detection limit≤3.33×10−8 M) and a rapid response time (≤15 s). The biological applications of RuH2bpip were also evaluated and it was found to exhibit low cytotoxicity, good water solubility, and membrane permeability; RuH2bpip was, therefore, employed as a sensing probe for the detection of Cu2+ in living cells and zebrafish.
