The construction of a Civic Neighbourhood as/through cultural production: a discourse analytical approach to participatory art and temporary architecture
Authors: Paola Catenaccio  , Torange Khonsari  
Published: May 2018

This essay investigates the construction of a neighborhood in East London, both in its discursive and its socio-cultural and material dimensions. The analysis combines methodologies from the fields of critical discourse analysis, participatory art, temporary architecture and urban commons to offer a “thick description” of professional, political and discursive practices involved in the definition and creation of a civic neighbourhood. The analysis focuses on civic neighbourhood project in East London called InterAct while the pivotal point of the project was the building of a piece of temporary architecture, the planning and ongoing construction of a civic neighbourhood involved a much more far-reaching production of material and symbolic artifacts which jointly represent a form of position taking within a site of social, cultural and symbolic struggle (Bourdieu 1993, 30). The study provides a critical description of the InterAct project, illustrating its purpose, goals and rationale and critically examines some of the publicly available discursive artifacts which revolve around it. The research approach programmatically seeks to combine insights from multiple methodological research traditions in order to investigate a complex socio-cultural phenomenon with considerable possible political ramifications.

AbstractObjectiveIntraspinal human spinal cord‐derived neural stem cell (HSSC) transplantation is a potential therapy for amyotrophic lateral sclerosis (ALS); however, previous trials lack controls. This post hoc analysis compared ambulatory limb‐onset ALS participants in Phase 1 and 2 (Ph1/2) open‐label intraspinal HSSC transplantation studies up to 3 years after transplant to matched participants in Pooled Resource Open‐Access ALS Clinical Trials (PRO‐ACT) and ceftriaxone datasets to provide required analyses to inform future clinical trial designs.MethodsSurvival, ALSFRS‐R, and a composite statistic (ALS/SURV) combining survival and ALS Functional Rating Scale revised (ALSFRS‐R) functional status were assessed for matched participant subsets: PRO‐ACT n = 1108, Ph1/2 n = 21 and ceftriaxone n = 177, Ph1/2 n = 20.ResultsSurvival did not differ significantly between cohorts: Ph1/2 median survival 4.7 years, 95% CI (1.2, ∞) versus PRO‐ACT 2.3 years (1.9, 2.5), P = 1.0; Ph1/2 3.0 years (1.2, 5.6) versus ceftriaxone 2.3 years (1.8, 2.8), P = 0.88. Mean ALSFRS‐R at 24 months significantly differed between Ph1/2 and both comparison cohorts (Ph1/2 30.1 ± 8.6 vs. PRO‐ACT 24.0 ± 10.2, P = 0.048; Ph1/2 30.7 ± 8.8 vs. ceftriaxone 19.2 ± 9.5, P = 0.0023). Using ALS/SURV, median PRO‐ACT and ceftriaxone participants died by 24 months, whereas median Ph1/2 participant ALSFRS‐Rs were 23 (P = 0.0038) and 19 (P = 0.14) in PRO‐ACT and ceftriaxone comparisons at 24 months, respectively, supporting improved functional outcomes in the Ph1/2 study.InterpretationComparison of Ph1/2 studies to historical datasets revealed significantly improved survival and function using ALS/SURV versus PRO‐ACT controls. While results are encouraging, comparison against historical populations demonstrate limitations in noncontrolled studies. These findings support continued evaluation of HSSC transplantation in ALS, support the benefit of control populations, and enable necessary power calculations to design a randomized, sham surgery‐controlled efficacy study.

Published: May 2018

AbstractThe emergence of states of matter in low‐dimensional systems is one of the most intriguing topics in condensed matter physics. Interfaces between nonmagnetic, insulating oxides are found to give rise to surprising behaviors, such as metallic conductivity, superconductivity, and magnetism. Sensitive, noninvasive local characterization tools are essential for understanding the electronic and magnetic behavior of these systems. Here, the scanning superconducting quantum interference device (SQUID) technique for local magnetic imaging is described and its contribution to the field of oxide interfaces is reviewed.
Self‐Assembled Nanostructured Photonic‐Plasmonic Metasurfaces for High‐Resolution Optical Thermometry

Published: May 2018

AbstractSensing devices for environment, safety, healthcare, and optoelectronic applications require an accurate and noninvasive monitoring of their temperature, because its variations markedly affect the overall response of the device. Monitoring the optical response of temperature‐sensitive integrated photonic elements, such as microresonators or microinterferometers, is an appealing solution in this context. However, achieving high‐resolution optical thermometry with such elements is unpractical and costly as this requires lithography processing, highly monochromatic laser sources, complex light coupling strategies. Here, a photonic‐plasmonic metasurface design that enables practical optical thermometry with a sub‐10−3 °C resolution is proposed. It is based on a self‐assembled nanostructured material implemented with a lithography‐free process. The optical response of the temperature‐sensitive metasurface is probed using a white light source and by monitoring the optical phase in a standard reflectance configuration. This facile, yet powerful, sensing scheme stands on the effective response of the metasurface, which involves the hybridization of thin film interference and low‐quality‐factor plasmon resonances to enable a quasi‐darkness response with a sharp spectral variation (jump) of the optical phase. Such jump is equivalent with a high‐quality‐factor resonator that yields a high sensor responsivity and thus enables high‐resolution optical thermometry.

Published: May 2018

AbstractOrganic field‐effect transistors (OFETs)‐based sensors have a great potential to be integrated with the next generation smart surgical tools for monitoring different real‐time signals during surgery. However, allowing ultraflexible OFETs to have compatibility with standard medical sterilization procedures remains challenging. A novel capsule‐like OFET structure is demonstrated by utilizing the fluoropolymer CYTOP to serve both encapsulation and peeling‐off enhancement purposes. By adapting a thermally stable organic semiconductor, 2,10‐diphenylbis[1]benzothieno[2,3‐d;2′,3′‐d′]naphtho[2,3‐b;6,7‐b′]dithiophene (DPh‐BBTNDT), these devices show excellent stability in their electrical performance after sterilizing under boiling water and 100 °C‐saturated steam for 30 min. The ultrathin thickness (630 nm) enables the device to have superb mechanical flexibility with smallest bending radius down to 1.5 µm, which is essential for application on the highly tortuous medical catheter inside the human body. By immobilizing anti‐human C‐reactive protein (CRP) (an inflammation biomarker) monoclonal antibody on an extended gate of the OFET, a sensitivity for detecting CRP antigen down to 1 µg mL−1 can be achieved. An ecofriendly water floatation method realized by employing the wettability difference between CYTOP and polyacrylonitrile (PAN) can be used to transfer the device on a ventricular catheter, which successfully distinguishes an inflammatory patient from a healthy one.

Published: May 2018

AbstractIt is of great interest and big challenge to control the collective behaviors of nanomotors to mimic the aggregation/separation behavior of biological systems. Here, a light‐acoustic combined method is proposed to control the aggregation/separation of artificial nanomotors. It is shown that nanomotors aggregate at the pressure node in acoustic field and afterward present a collective “firework” separation behavior induced by light irradiation. The collective behavior is found to be applicable for metallic materials and polymers even different light wavelengths are used. Physical insights on the collective firework behavior resulting from the change of acoustic streaming caused by optical force are provided. It is found that diffusion velocity and diffusion region of cluster can be controlled by adjusting light intensity and acoustic excitation voltage, and irradiation direction, respectively. This harmless, controllable, and widely applicable method provides new possibilities for groups of nanomachines, drug release, and cargo transport in nanomedicine and nanosensors.

AbstractCobalt‐free layered lithium‐rich nickel manganese oxides, Li[LixNiyMn1−x−y]O2 (LLNMO), are promising positive electrode materials for lithium rechargeable batteries because of their high energy density and low materials cost. However, substantial voltage decay is inevitable upon electrochemical cycling, which makes this class of materials less practical. It has been proposed that undesirable voltage decay is linked to irreversible structural rearrangement involving irreversible oxygen loss and cation migration. Herein, the authors demonstrate that the voltage decay of the electrode is correlated to Mn4+/Mn3+ redox activation and subsequent cation disordering, which can be remarkably suppressed via simple compositional tuning to induce the formation of Ni3+ in the pristine material. By implementing our new strategy, the Mn4+/Mn3+ reduction is subdued by an alternative redox reaction involving the use of pristine Ni3+ as a redox buffer, which has been designed to be widened from Ni3+/Ni4+ to Ni2+/Ni4+, without compensation for the capacity in principle. Negligible change in the voltage profile of modified LLNMO is observed upon extended cycling, and manganese migration into the lithium layer is significantly suppressed. Based on these findings, we propose a general strategy to suppress the voltage decay of Mn‐containing lithium‐rich oxides to achieve long‐lasting high energy density from this class of materials.

BackgroundHospital readmissions are an increasingly scrutinized marker of surgical care delivery and quality. There is a paucity of information in the literature regarding the rate, risk factors, and common causes of readmission after surgery for sinonasal cancer.MethodsWe analyzed the Nationwide Readmissions Database for patients who underwent surgery for a diagnosis of sinonasal cancer between 2010 and 2014. Rates, causes, and patient‐, procedure‐, and hospital‐level risk factors for 30‐day readmission were determined. Multivariate logistic regression was used to identify predictors of 30‐day readmission.ResultsAmong the 4173 cases, the 30‐day readmission rate was 11.6%, with an average cost per readmission of $18,403. The most common readmission diagnoses were wound complications (15.3%) and infections (13.4%). On multivariate regression, significant risk factors for readmission were chronic renal failure (odds ratio [OR], 2.95; 95% confidence interval [CI], 1.41‐6.17), involvement of the skull base or orbit (OR, 1.67; 95% CI, 1.11‐2.51), nonelective initial surgical admission (OR, 2.35; 95% CI, 1.42‐3.89), and length of stay ≥7 days (OR, 1.87; 95% CI, 1.14‐3.05).ConclusionThrough the use of a large national database, we found that approximately 1 in 9 patients undergoing surgery for sinonasal cancer was readmitted within 30 days. Readmissions were most commonly associated with wound complications and infections. Factors related to procedural complexity were more important predictors of readmission than patients’ demographics or comorbidities.

Published: May 2018

AbstractWe present an investigation of isostructural complexes that feature unsupported direct bonds between a formally trivalent lanthanide ion (Dy3+) and either a first‐row (Fe) or a second‐row (Ru) transition metal (TM) ion. The sterically rigid, yet not too bulky ligand PyCp22−(PyCp22−=[2,6‐(CH2C5H3)2C5H3N]2−) facilitates the isolation and characterization of PyCp2Dy−FeCp(CO)2(1;d(Dy–Fe)=2.884(2) Å) and PyCp2Dy−RuCp(CO)2(2;d(Dy–Ru)=2.9508(5) Å). Computational and spectroscopic studies suggest strong TM→Dy bonding interactions. Both complexes exhibit field‐induced slow magnetic relaxation with effectively identical energy barriers to magnetization reversal. However, in going from Dy−Fe to Dy−Ru bonding, we observed faster magnetic relaxation at a given temperature and larger direct and Raman coefficients, which could be due to differences in the bonding and/or spin–phonon coupling contributions to magnetic relaxation.

Published: May 2018

AbstractCatalysis with earth‐abundant transition metals is an option to help save our rare noble‐metal resources and is especially interesting when novel reactivity or selectivity patterns are observed. We report here on a novel reaction, namely the dehydrogenative alkylation or α‐olefination of alkyl‐substituted N‐heteroarenes with alcohols. Manganese complexes developed in our laboratory catalyze the reaction with high efficiency whereas iron and cobalt complexes stabilized by the same ligands are essentially inactive. Hydrogen is liberated during the reaction, and bromine and iodine functional groups as well as olefins are tolerated. A variety of alkyl‐substituted N‐heteroarenes can be functionalized, and benzylic and aliphatic alcohols undergo the reaction.

AbstractTo address the anticipated global need for increased protein supply for human nutrition, particularly for developing and underdeveloped regions, concerted efforts are required. Although animal proteins satisfy nutrition needs, they may not be acceptable to all consumers either due to their cost or dietary restrictions followed by the consumer. Soybean has served as a nonanimal protein source; however, alternative protein sources will need to be cultivated and explored in the future to satisfy anticipated increased global needs. To effectively utilize a food protein source, separation of proteins from the nonprotein components present in that source is often needed or desired. Such separation requires understanding of protein properties and interactions of the protein with its environment. In chemical separation processes, protein solubility is a critical property as it often governs protein preparation and utilization and is the focus of this review. Emphasis is on nontraditional protein sources.

Published: May 2018

ABSTRACTThe Monte Carlo simulation of filled conductive polymer materials is a method of continuously generating a random conformation and averaging the interesting results to simulate the random dispersion of fillers in space. In our simulation, the irregular shapes of the filler were abstracted into regular ones. Carbon black (CB) aggregates were modeled as spheres, and carbon nanotubes (CNTs) were modeled as capped cylinders. The connection of the fillers was estimated via the calculation of the shortest distance between them; this determined whether a percolation pathway was formed or not. Numerical results were obtained, and these highlight the effects of the filler size, including the aspect ratio of CNTs and the ratio of the diameter of the CB aggregates to the diameter of the CNTs on the electrical percolation threshold (EPT). We found that the EPT decreased with increasing CNT aspect ratio and decreased the diameter ratio of the CB aggregates to CNTs. The simulation results were obtained by a simple pathway‐finder algorithm, which was proven to be effective compared with existing numerical, theoretical, and experimental simulations. © 2018 Wiley Periodicals, Inc.

Authors: Rao Bin , Kinjo Rei 
Published: May 2018

AbstractBecause the construction of the C−C bond is one of the most significant reactions in organic chemistry, the development of an efficient strategy has attracted much attention throughout the synthetic community. Among various protocols to form C−C bonds, organoboron compounds are not just limited to stoichiometric reagents, but have also made great achievements as catalysts because of the easy modification of the electronic and steric impacts on the boron center. This review presents recent developments of boron‐based catalysts applied in the field of C−C bond‐formation reactions, which are classified into four kinds on the basis of the type of boron catalyst: 1) highly Lewis acidic borane, B(C6F5)3; 2) organoboron acids, RB(OH)2, and their ester derivatives; 3) borenium ions, (R2BL)X; and 4) other miscellaneous kinds.

Authors: Le Hien Van , Chu Kinh Trong 
Published: May 2018

AbstractThe problem of robust decentralized control of positive fractional‐order interconnected systems with heterogeneous time‐varying delays is studied in this paper. Necessary and sufficient conditions are first derived for internal positiveness of the system. By exploiting the monotonicity induced from positivity of the system, robust stability conditions subject to uncertain system parameters are derived. The derived stability conditions are then utilized to address the controller synthesis problem. The design conditions for obtaining controller gains of stabilizing decentralized controllers are formulated using linear programming, which can be effectively solved by various convex optimization algorithms. Finally, the effectiveness of the obtained results is validated by two numerical examples.

Published: May 2018

AbstractThe problem of non‐fragile extended dissipative control design for a class of generalized neural networks (GNNs) with interval time‐delay signals is investigated in this paper. By constructing a suitable Lyapunov‐Krasovskii functional (LKF) with double and triple integral terms, and estimating their derivative by using the Wirtinger single integral inequality (WSII) and Wirtinger double integral inequality (WDII) technique respectively, and that is mixed with the reciprocally convex combination (RCC) approach. A new delay‐dependent non‐fragile extended dissipative control design for GNNs are expressed in terms of the linear matrix inequalities (LMIs). Then, the desired non‐fragile extended dissipative controller can be obtained by solving the linear matrix inequalities (LMIs). Furthermore, a non‐fragile state feedback controller is designed for GNNs such that the closed‐loop system is extended dissiptive. Thus, the non‐fragile extended dissipative controller can be adopted to deal with the non‐fragile
performance, non‐fragile
performance, non‐fragile passive performance, non‐fragile mixed
and passivity performance, and non‐fragile dissipative performance for GNNs by selecting the weighting matrices. Finally, simulation studies are demonstrated for showing the feasibility of the proposed method. Among them, one example was supported by the real‐life application of the quadruple tank process system.

Published: May 2018

AbstractSingle‐walled carbon nanotubes (SWCNTs) are made from a rolled single sheet of graphene with a diameter in the nanometer range. SWCNTs are potential carriers for drug delivery systems because antibodies or drugs can be loaded on their surface; however, their effect on the activities of cytochrome P450 (CYP) remains unclear. The aim of this study was to investigate the effect of two kinds of SWCNTs with different lengths (FH‐P‐ and SO‐SWCNTs) on human CYP activity. In addition, other nano‐sized carbon materials, such as carbon black, fullerene‐C60, and fullerene‐C70 were also evaluated to compare their effects on CYP activities. Ten CYP substrates (phenacetin, coumarin, bupropion, paclitaxel, tolbutamide, S‐mephenytoin, dextromethorphan, chlorzoxazone, midazolam, and testosterone) were used. Testosterone 6β‐hydroxylation and midazolam 1′‐hydroxylation, which are catalysed by both CYP3A4 and CYP3A5 in liver microsomes, were decreased by 25% and 45%, respectively, in the presence of 0.1 mg/ml SO‐SWCNT. Dextromethorphan O‐demethylation, which is catalysed mainly by CYP2D6, was decreased by 40% in the presence of SO‐SWCNT. Other CYP activities, however, were not attenuated by SO‐SWCNT. FH‐P‐SWCNT, carbon black, fullerene‐C60, and fullerene‐C70 at 0.1 mg/ml had no effect on CYP activities. The Ki values for testosterone 6β‐hydroxylation, midazolam 1′‐hydroxylation, and dextromethorphan O‐demethylation in liver microsomes were 136, 34, and 56 μg/ml, respectively. SO‐SWCNT was determined to be a competitive inhibitor of CYP3A4, CYP3A5, and CYP2D6. These results suggest that the effect of SO‐SWCNT differs among CYP isoforms, and that the inhibition potency depends on the physicochemical properties of the nanocarbons.
