Chantal Maillard. Una experiencia común del vacío / Chantal Maillard. A common experience of emptiness
Authors: Martínez García Miguel Ángel 
Published: January 2018

Resumen: Este artículo se acerca a la experiencia de malestar que se elabora en la obra de Chantal Maillard y que podríamos reconocer (tal es nuestra propuesta) como una “experiencia del vacío”. A través del análisis de sus obras (poéticas, diarios, ensayos, etc.), y del apoyo en textos de teoría psicoanalítica y filosofía política, llegamos a la conclusión de que solo a partir de la elaboración de dicha experiencia (en la que el vacío no es taponado ni colmado) esta puede ser leída como una experiencia de “cualquiera” y, por tanto, de algún modo, como una experiencia “común”.
Palabras clave: Vacío, Cuerpo, Experiencia, Común, Cualquiera.

Abstract: This paper approaches the experience of unease in Chantal Maillard’s work, which we could identify as an “experience of emptiness”. Through the analysis of her works (poems, diaries, essays, etc.), and also through a theoretical frame based on a psychoanalytic and a philosophical approach, we will conclude that it is only through the working out of this experience (in which emptiness cannot be blocked or even fullfilled), that it can be understood as an “anyone’s experience”, and therefore as a “common” experience.

Keywords: Emptiness, Body, Experience, Common, Anyone.
AIR TRANSPORT PRIVATIZATION TRENDS

Published: January 2018

It is important to consider basic principles, practical results and consequences, in order to understand practical results and consequences of privatization. In case of airline privatization trends, it is obvious that this process is very intensive, but without guarantee for success on the air transport market. Analysis of the European airlines members of Association of European Airlines in the period 1991-2015 is confirming trends of privatization for solving the problem of “distressed state airline syndrome”, Airline foreign ownership and control rules is one of the limiting factors in privatization processes worldwide. Procedures and principles for the privatization process of airports and air navigation services are in accordance with ICAO’s standards and recommended practices.The ownership structure is not the central issue of an airport privatization with different structure of solutions in practice. In the sector of Air Navigation Services or Air Traffic Control, privatization is not so frequent but still existing. From government perspective, it is important for the selected operator to be well reputed, financially stable and experienced enough. Analysis of air transport privatization points out complexity of different options in process of sustainability in very dynamic global changes and challenges on the aviation market.

Published: January 2018

Objective
We compared the application of artificial dermis composite tissue flaps and traditional prefabricated flaps in a rat model of exposed bone and tendon injury.

Methods
Sprague Dawley rats were randomly divided into two groups (n = 40 per group). Group A rats received artificial dermis composite tissue flaps and group B rats received traditional prefabricated flaps. Flap appearance, range of motion, degree of swelling, tissue histologic results, and imaging findings were compared between groups at 7, 14, 21, and 28 days.

Results
There was no difference in flap appearance, range of motion, or degree of swelling between groups. However, blood perfusion of the artificial dermis composite tissue flap was better than that of the traditional prefabricated flap; the artificial dermis was also found to be thicker than the traditional prefabricated flap.

Conclusions
The artificial dermis composite tissue flap is an ideal method for repairing exposed bone and tendon, and it displays repair effects comparable with those of the traditional prefabricated flap and may be a better alternative.

Dawn‐Dusk Auroral Oval Oscillations Associated With High‐Speed Solar Wind
Authors: Liou Kan , Sibeck David G. 
Published: January 2018

AbstractWe report evidence of global‐scale auroral oval oscillations in the millihertz range, using global auroral images acquired from the Ultraviolet Imager on board the decommissioned Polar satellite and concurrent solar wind measurements. On the basis of two events (15 January 1999 and 6 January 2000) studied, it is found that (1) quasi‐periodic auroral oval oscillations (~3 mHz) can occur when solar wind speeds are high at northward or southward interplanetary magnetic field turning, (2) the oscillation amplitudes range from a few to more than 10° in latitudes, (3) the oscillation frequency is the same for each event irrespective of local time and without any azimuthal phase shift (i.e., propagation), (4) the auroral oscillations occur in phase within both the dawn and dusk sectors but 180° out of phase between the dawn and dusk sectors, and (5) no micropulsations on the ground match the auroral oscillation periods. While solar wind conditions favor the growth of the Kelvin‐Helmholtz (K‐H) instability on the magnetopause as often suggested, the observed wave characteristics are not consistent with predictions for K‐H waves. The in‐phase and out‐of‐phase features found in the dawn‐dusk auroral oval oscillations suggest that wiggling motions of the magnetotail associated with fast solar winds might be the direct cause of the global‐scale millihertz auroral oval oscillations.
Modeling Thermal Pressurization Around Shallow Dikes Using Temperature‐Dependent Hydraulic Properties: Implications for Deformation Around Intrusions
Authors: Townsend Meredith R. 
Published: January 2018

AbstractPressurization and flow of groundwater around igneous intrusions depend in part on the hydraulic diffusivity of the host rocks and processes that enhance diffusivity, such as fracturing, or decrease diffusivity, such as mineral precipitation during chemical alteration. Characterizing and quantifying the coupled effects of alteration, pore pressurization, and deformation have significant implications for deformation around intrusions, geothermal energy, contact metamorphism, and heat transfer at mid‐ocean ridges. Fractures around dikes at Ship Rock, New Mexico, indicate that pore pressures in the host rocks exceeded hydrostatic conditions by at least 15 MPa following dike emplacement. Hydraulic measurements and petrographic analysis indicate that mineral precipitation clogged the pores of the host rock, reducing porosity from 0.25 to <0.10 and reducing permeability by ~5 orders of magnitude. Field data from Ship Rock are used to motivate and constrain numerical models for thermal pore fluid pressurization adjacent to a meter‐scale dike, using temperature‐dependent hydraulic properties in the host rock as a proxy for porosity loss by mineral precipitation during chemical alteration. Reduction in permeability by chemical alteration has a negligible effect on pressurization. However, reduction in porosity by mineral precipitation increases fluid pressure by constricting pore volume and is identified as a potentially significant source of pressure. A scaling relationship is derived to determine when porosity loss becomes important; if permeability is low enough, pressurization by porosity loss outweighs pressurization by thermal expansion of fluids.
Particle‐Based Modeling of Pull‐Apart Basin Development
Authors: Liu Yuan , Konietzky Heinz 
Published: January 2018

AbstractA scale‐independent modeling approach based on the discrete element method has been established to investigate the development of pull‐apart basins. The main findings can be summarized as follows. Thirty degree underlapping models produce pull‐apart basins that evolve from spindle‐shaped through lazy‐Z‐shaped to rhomboidal and stretched rhomboidal basin. Ninety degree nonoverlapping and 150° overlapping models generate rhomboidal pull‐apart basins without going through spindle‐shaped and lazy‐Z‐shaped stages. The shape of a pull‐apart basin is the consequence of both the initial strike‐slip fault geometry and its various evolution stages. Rhomboidal basins, which have larger basin length than the amount of motion, form in overlapping systems and do not progress through the spindle‐shaped and lazy‐Z‐shaped stages such as the Dead Sea basin. Rhomboidal basins with cross‐basin faults tend to form in underlapping systems. All the numerical models show nearly the same trend for maximum principal stress versus relative extension εx* (horizontal opening divided by fault separation). Peak stress and onset of crack propagation are observed for εx* of ~0.035. The relative extension to form the first depression is ~0.155. Therefore, for a pull‐apart to form in nature, the displacement and time needed to form the first cracks and depression area can be estimated from the corresponding εx* and the slip rate of the strike‐slip faults. The time needed to form the first depression can be considered as the minimum age of initiation for the pull‐apart basin. This method to deduce the starting age of pull‐apart basin development can be used for basins which are still active.
Attribution of Large‐Scale Climate Patterns to Seasonal Peak‐Flow and Prospects for Prediction Globally
Authors: Lee Donghoon , Ward Philip , Block Paul 
Published: January 2018

AbstractFlood‐related fatalities and impacts on society surpass those from all other natural disasters globally. While the inclusion of large‐scale climate drivers in streamflow (or high‐flow) prediction has been widely studied, an explicit link to global‐scale long‐lead prediction is lacking, which can lead to an improved understanding of potential flood propensity. Here we attribute seasonal peak‐flow to large‐scale climate patterns, including the El Niño Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), and Atlantic Multidecadal Oscillation (AMO), using streamflow station observations and simulations from PCR‐GLOBWB, a global‐scale hydrologic model. Statistically significantly correlated climate patterns and streamflow autocorrelation are subsequently applied as predictors to build a global‐scale season‐ahead prediction model, with prediction performance evaluated by the mean squared error skill score (MSESS) and the categorical Gerrity skill score (GSS). Globally, fair‐to‐good prediction skill (20% ≤ MSESS and 0.2 ≤ GSS) is evident for a number of locations (28% of stations and 29% of land area), most notably in data‐poor regions (e.g., West and Central Africa). The persistence of such relevant climate patterns can improve understanding of the propensity for floods at the seasonal scale. The prediction approach developed here lays the groundwork for further improving local‐scale seasonal peak‐flow prediction by identifying relevant global‐scale climate patterns. This is especially attractive for regions with limited observations and or little capacity to develop flood early warning systems.
Social Position Influencing the Water Perception Gap Between Local Leaders and Constituents in a Socio‐Hydrological System
Authors: Haeffner Melissa , Jackson‐Smith Douglas , Flint Courtney G 
Published: January 2018

AbstractHow well city leaders represent their constituents and meet their needs are key concerns in transitioning to local sustainable water governance. To date, however, there is little research documenting the influence of social position between elected leaders who make policy, career staff water managers who design and operate systems and implement policies, and the members of the public whose individual water use behaviors are important drivers of water sustainability outcomes. In this study, we ask: “How does social position explain variation in water perceptions and concerns between different actors in a socio‐hydrological system?” Using a mixed method approach with survey and interview data, we explore the ways that positioning within the governance system, geographic context, and citizen engagement in local government mediate perceptions of the urban water system. Regardless of local biophysical water supply conditions, residents showed most concern about future water shortages and high water costs, while their leaders were consistently most concerned about deteriorating local water infrastructure. Further, constituents who received water‐related information directly from public utility mailings or served on community committees and boards had perceptions that were more aligned with leaders' concerns. The importance of social structure over natural and built environments in shaping water issue perceptions underscores the value of social analysis in socio‐hydrology studies. Further, practitioners looking to increase consensus for a transition to sustainable water governance might work to develop institutional mechanisms to increase opportunities for water user involvement in local water system governance.

Published: January 2018

AbstractInspired by the machines that have changed the world through their autonomous functions, scientists have focused their attention on performing similar functions at the micro/nanoscale. The motility of these micro/nanomachines (micro/nanomotors) offers enormous opportunities for cargo delivery, biodetection, and environmental and biomedical applications. Among the various geometries of micro/nanomotors, a tubular shape provides asymmetric inner and outer surfaces, where the inner wall hosts chemical reactions that supply the moving power and the outer wall can be modified for specific chemical and biological functions. This review describes the concept of tubular micro/nanomotors, including their basic principles, fabrication methods and control over their motion. With the assistance of catalytic reactions, tubular micro/nanomotors can generate a powerful thrust force to navigate in complex natural and in vitro environments. Modification of the tubular micro/nanomotors allows the motors to capture, transport, and release selected cargos on demand. In addition, their application in sensing and decontamination benefits from their collection behavior and self‐mixing effect. Furthermore, noncatalytic reaction‐driven tubular micro/nanomotors, such as redox‐based and biohybrid tubular micro/nanomotors, provide new possibilities for practical in vivo applications. The state‐of‐the‐art tubular micro/nanomotors could offer a promising platform for various applications, e.g., lab‐on‐chip devices and in vivo theranostics.

AbstractCoexistence of negative differential resistance (NDR) and resistive switching (RS) memory is observed using a Ag|TiOx|F‐doped‐SnO2memory cell at room temperature. Unlike other reports, the coexistence of NDR and RS strongly depends on the relative humidity levels at room temperature. The NDR disappears when the cells are placed in a dry air ambient (H2O < 5 ppm) or in vacuum, but the coexistence emerges and gradually becomes obvious after the cells are exposed to ambient air with relative humidity of 35%, and then becomes dramatically enhanced as the relative humidity becomes higher. Due to the excellent stability and reversibility of the coexistence of NDR and RS, a multilevel RS memory is developed at room temperature. Hydroxide ion (OH−) is induced by gas‐phase water‐molecule splitting on the surface and interface of the memory cell. The OH−interacts with oxygen vacancies and transports in the bulk of memory cell to facilitate the migration of Ag ions and oxygen vacancies along grain boundaries. These processes are responsible for the moisture‐modulated and room‐temperature coexistence. This work demonstrates moisture‐modulated coexistence of NDR and RS for the first time and gives an insight into the influence of water molecules on transition‐metal‐oxide‐based RS memory systems.

Published: January 2018

AbstractThe thia‐Michael addition reaction has been demonstrated to be a highly powerful tool in organic synthesis. Indeed, the influential nature of this reaction has been well‐established in the fields of medicinal chemistry, catalysis, drug discovery, and materials science. The emergence of numerous synthetic strategies that take advantage of thia‐Michael addition reactions of electron‐deficient alkenes has unleashed countless opportunities for the design and synthesis of diverse biologically relevant organosulfur compounds. However, despite myriad potential synthetic applications, there has not been any exclusive reviews of the thia‐Michael addition reaction. Therefore, this Focus Review plots the journey of the thia‐Michael addition reaction in organic synthesis, and is categorized according to catalyzed and catalyst‐free thia‐Michael addition reactions.

AbstractVicinal diols and their derivatives are common motifs in a large number of biologically active compounds and are also important intermediates in organic synthesis. To achieve these structural units in a highly stereoselective manner, direct dioxygenation of simple alkene precursors has proved to be the most straightforward approach, and thus many practical procedures using various strategies have been developed. In this Focus Review a concise summary of the main methods for anti‐dioxygenation of olefins is presented.

Published: January 2018

AbstractAcceptor–donor–acceptor (A–D–A) is an effective molecular design strategy for organic small molecules. In this work, we reported a simple A–D–A small molecule (TBDT‐2HT‐ID), with thiophene‐substituted benzodithiophene (TBDT) as a core, 1H‐indene‐1,3(2H)‐dione (ID) as end‐capped acceptor, and linked by the π‐bridge of 3,6‐dihexylthieno[3,2‐b]thiophene. UV and CV results showed that the molecule exhibited good absorption in the range of 300–700 nm but a very low HOMO energy level (−5.47 eV). Grazing incidence X‐ray diffraction (GIXRD) results demonstrate it has good crystallinity and adopts an edge‐on molecular packing, and consequently its hole mobility could reach 1×10−3 cm2 V‐1S−1. Based on PC71BM as acceptor, TBDT‐2HT‐ID had an excellent power conversion efficiency with 7.4 % without any post‐treatment, and a very high Voc of 1.07 V, which would be one of the highest Voc reported so far.
Copper‐Catalyzed Enantioselective Arylative Desymmetrization of Prochiral Cyclopentenes with Diaryliodonium Salts
Authors: Wu Hua , Wang Qian , Zhu Jieping 
Published: January 2018

AbstractA copper‐catalyzed enantioselective arylative desymmetrization of prochiral cyclopentenes with diaryliodonium salts was developed. In the presence of a catalytic amount of a chiral copper–bisoxazoline complex, which was generated in situ, the reaction of 4‐substituted or 4,4‐disubstituted cyclopent‐1‐enes with diaryliodonium hexafluoroarsenates afforded the chiral arylated products in good yields with excellent enantioselectivity. A cyclohexyl‐containing Box ligand was essential for the high enantioselectivity. Transformation of the enantiomerically enriched adducts into other chiral building blocks is also documented.
