El sentido de la democracia en la filosofía estética de Jean-Luc Nancy
Authors: Sánchez Mayor Paula 
Published: November 2019

Atendiendo a las premisas del IV Congreso Estética y Política se propone una comunicación en torno a los trabajos que el filósofo francés Jean-Luc Nancy ha dedicado a la noción de democracia desde una perspectiva estética propia de la filosofía de este autor. Tomando como principal referencia la obra traducida al castellano La verdad de la democracia, la propuesta se centrará en la presencia de la noción heideggeriana ser-con (mit sein) en la elaboración del pensamiento de Nancy. Desde una comprensión del sentido atravesada por el estar juntos Nancy propone una vuelta de tuerca a la noción de democracia, instalándola en un régimen de inmanencia de sentido, más allá de ser entendida como un hecho histórico y administrativo. En este contexto el con que se articula en un régimen democrático adquiere unas características particulares que atañen directamente al ser de los entes. Ya en este nivel ontológico el filósofo pone el acento en la idea originaria de relación, superando la comprensión tradicional que consistiría en partir de los elementos para, después, apreciarlos en aquello que los pone en contacto. Así pues, el contacto deviene en creación de sentido previa a los mismos elementos relacionados. He aquí donde se puede encontrar la particular perspectiva estética de Nancy, que aparece en el corazón mismo de la ontología de este filósofo. A este respecto es fundamental señalar la relevancia de los textos que tienen como tema principal el sentido del cuerpo, ya que es ahí donde se puede indagar sobre esa particular relación que es el contacto y que crea sentido. Alguno de estos textos son Corpus, Archivida, Nuus sommes y La pensé dérobée. Por último, aunque atravesando en todo momento la comunicación, se encuentran los trabajos que el filósofo francés dedica al problema de la comunidad y la globalización. Estos trabajos ofrecen una profunda reflexión sobre la situación actual de la política y la sociedad. Dada la presencia que tiene el cuerpo en el pensamiento de Nancy será interesante mostrar su relación con la cuestión del mundo, la mundialización y la globalización. Lo que dará como resultado un replanteamiento de la noción de sentido en un mundo globalizado y capitalista. Para terminar, atender a la advertencia que impone Nancy al señalar que “no significa que cualquiera pueda hace sentido sin importar cómo. Ésta es, precisamente la versión capitalista de lo sin razón, que establece la equivalencia general de todas las formas de sentido en una informidad infinita” (La creación del mundo o la mundialización, 50).

<p>En el marco docente del segundo curso de Arquitectura de la Universidad de Zaragoza planteamos un ejercicio trasversal entre las áreas de Expresión Gráfica (Taller Integrado 1) y Proyectos (Proyectos 1). Para trabajar en un proyecto de ampliación de la casa Farnsworth de Mies van der Rohe, desarrollado gráficamente en el Taller 1, nos planteamos en primera instancia un ejercicio de exploración visual —a través del fotomontaje y el collage— para reconsiderar críticamente el carácter mítico de esta urna de cristal y sus potenciales estrategias operativas. Revisando los extraordinarios y sugerentes resultados alcanzados por los estudiantes este texto aspira brevemente a analizar y revalorar más si cabe esta técnica gráfica de representación arquitectónica en el ámbito docente y a poner en cuestión crítica y teóricamente la circunspecta identidad de los iconos modernos.</p>

Published: November 2019

<p>El presente artículo estudia los antecedentes de la primera exposición dedicada al diseño de mobiliario moderno en América organizada en el MoMA en 1941. Se constata que la gran mayoría de los diseños premiados en el concurso previo a la exposición fueron elaborados por jóvenes arquitectos, ya que eran los únicos que estaban al día de las tendencias modernas derivadas de la Bauhaus o del diseño escandinavo. Tanto el organizador, Eliot Noyes, como los premiados, Eero Saarinen y Charles Eames, despuntaron tras la guerra mundial como diseñadores de sobresaliente trayectoria profesional. Por último, resulta de interés comprobar el papel que llegaron a alcanzar los prototipos y maquetas a escala en los procesos de diseño de mobiliario.</p>
Atmosphere–ocean exchange of heavy metals and polycyclic aromatic hydrocarbons in the Russian Arctic Ocean
Authors: Ji Xiaowen , Abakumov Evgeny , Xie Xianchuan 
Published: November 2019

Abstract. Heavy metals and polycyclic aromatic hydrocarbons (PAHs) can
greatly influence biotic activities and organic sources in the ocean.
However, fluxes of these compounds as well as their fate, transport, and net
input to the Arctic Ocean have not been thoroughly assessed. During
April–November of the 2016 “Russian High-Latitude Expedition”, 51 air
(gases, aerosols, and wet deposition) and water samples were collected from the
Russian Arctic within the Barents Sea, the Kara Sea, the Laptev Sea, and the East
Siberian Sea. Here, we report on the Russian Arctic assessment of the
occurrence of 35 PAHs and 9 metals (Pb, Cd, Cu,
Co, Zn, Fe, Mn, Ni, and Hg) in dry and wet deposition as well as the atmosphere–ocean fluxes of 35
PAHs and Hg0. We observed that Hg was mainly in the gas phase and that
Pb was most abundant in the gas phase compared with the aerosol and
dissolved water phases. Mn, Fe, Pb, and Zn showed higher levels than the
other metals in the three phases. The concentrations of PAHs in aerosols and
the dissolved water phase were approximately 1 order of magnitude higher
than those in the gas phase. The abundances of higher molecular weight PAHs
were highest in the aerosols. Higher levels of both heavy metals and PAHs
were observed in the Barents Sea, the Kara Sea, and the East Siberian Sea, which
were close to areas with urban and industrial sites. Diagnostic ratios of
phenanthrene/anthracene to fluoranthene/pyrene showed a pyrogenic source for
the aerosols and gases, whereas the patterns for the dissolved water phase
were indicative of both petrogenic and pyrogenic sources; pyrogenic sources
were most prevalent in the Kara Sea and the Laptev Sea. These differences
between air and seawater reflect the different sources of PAHs through
atmospheric transport, which included anthropogenic sources for gases and
aerosols and mixtures of anthropogenic and biogenic sources along the
continent in the Russian Arctic. The average dry deposition of ∑9 metals and ∑35 PAHs was 1749 and 1108 ng m−2 d−1, respectively. The average wet deposition of ∑9 metals and ∑35 PAHs was 33.29 and
221.31 µg m−2 d−1, respectively. For the atmosphere–sea
exchange, the monthly atmospheric input of ∑35 PAHs was estimated
at 1040 t. The monthly atmospheric Hg input was approximately 530 t.
These additional inputs of hazardous compounds may be disturbing the
biochemical cycles in the Arctic Ocean.
Addressing Physical Activity Behavior in Multiple Sclerosis Management

Published: November 2019

Abstract

Background:
Although physical activity (PA) is considered the most important nonpharmaceutical intervention for persons with multiple sclerosis (MS), less than 20% of people with MS are engaging in sufficient amounts to accrue benefits. Promotion of PA is most effective when combined with additional behavior change strategies, but this is not routinely done in clinical practice. This study aimed to increase our understanding of current practice and perspectives of health care providers (HCPs) in Canada regarding their use of interventions to address PA behavior in MS management. Investigating HCPs’ perspectives on implementing PA behavior change with persons with MS will provide insight into this knowledge-to-practice gap.

Methods:
Semistructured focus groups were conducted with 31 HCPs working with persons with MS in Saskatchewan, Canada. Based on interpretive description, data were coded individually by three researchers, who then collaboratively developed themes. Analysis was inductive and iterative; triangulation and member reflections were used.

Results:
Five themes were established: 1) prescribing, promoting, and impacting wellness with PA; 2) coordinating communication and continuity in practice; 3) timely access to relevant care: being proactive rather than reactive; 4) enhancing programming and community-based resources; and 5) reconciling the value of PA with clinical practice.

Conclusions:
The HCPs value PA and want more support with application of behavior change strategies to deliver PA behavioral interventions, but due to the acute and reactive nature of health care systems they feel this cannot be prioritized in practice. Individual- and system-level changes are needed to support consistent and effective use of PA behavioral interventions in MS.
QSAR, Docking Study of Isatin Analogues as Anti-bacterial Agents for Design New Compounds
Authors: Sabet Razieh , Jafroudi Isar 
Published: November 2019

Computational chemistry is unique method in drug discovery which reduce cost. In this study 86 molecules containing isatin core were subjected to quantitative structure-activity relationship analysis and docking study to find the structure requirements for ligand binding. The structures were sketched and optimized in Hyperchem. The structural invariants used in this study were those obtained from whole molecular structures: by both hyperchem and dragon software (16 types of descriptors). Four chemometrics methods including MLR, FA-MLR, PCR and GA-PLS were employed to make connection between structural parameters and anticancer effects. MLR analysis explained the positive effect of the number of urea derivatives, thio urea, amide, thioamide, hydrazone, thiocarbohydrazone, nBnz with the halogen substitution on 5 position of isatin ring on the antimicrobial activity. It also shows nArCN, nPyridines have negative effects on the antimicrobial activity of studied compound.
The FA-MLR describes the effect of 3D-MORSE and Galvez Topological charge descriptors and on antimicrobial activity of the studied compounds. The quality of PCRA equation is better than those derived from FA-MLR. A comparison between the different statistical methods employed revealed that GA-PLS represented superior results and it could explain and predict 73% and 68% of variances in the –LogMIC data, respectively. Comparison between QSAR and docking analysis revealed that by decreasing in number of ring and lipophilicity (also Logp) for design of new compounds can have better activity. Substitutions such as urea, thiourea, thiocarbohydrazone, benzhydrazide as on isatin ring, can cause better interaction with receptor.
Optimal stimulation toward the dermal papilla lineage can be promoted by combined use of osteogenic and adipogenic inducers

Published: November 2019

Dermal papilla cells (DPCs) play crucial roles in hair regeneration, but they readily lose their hair‐forming ability during in vitro culture. Although the formation of spheroids partially restores the ability, shrinkage of the spheroids makes it difficult to maintain cellular viability. To address this problem, we stimulated DPCs with factors known to induce adipogenic and/or osteogenic differentiation, because DPCs share unique gene expression profiles with adipocytes and osteocytes. We isolated DPCs from versican (vcan)–GFP mice, in which GFP is expressed under the control of a vcan promoter, which is strongly active in DPCs of anagen hair follicles. GFP fluorescence was most intense when the spheroids were made from DPCs cultured in a half‐diluted combination of adipogenic and osteogenic media (CAO1/2), a Dulbecco’s modified Eagle’s medium‐based medium that contains 10% FBS, 275 nm dexamethasone, 2.5 mm β‐glycerol phosphate, 12.5 µg·mL−1 ascorbic acid, 0.125 µm isobutylmethylxanthine and 2.5 ng·mL−1 insulin. The dose of each additive used was less than the optimal dose for adipogenic or osteogenic differentiation, and shrinkage of the spheroids was avoided through the addition of fibroblast growth factor 2 and platelet‐derived growth factor‐AA to CAO1/2. In addition, the gene and protein expression of vcan, osteopontin, alkaline phosphatase and α‐smooth muscle actin in the spheroids were augmented to levels similar to those of the intact dermal papillae, which exhibited restored hair‐forming activity. In conclusion, a combination of certain adipogenic and osteogenic inducers, together with fibroblast growth factor 2 and platelet‐derived growth factor‐AA, can promote differentiation toward the DPC lineage.
Estimation: General Aspects
Authors: Bedrick Edward J. 
Published: November 2019

Abstract
This entry is concerned with the relationship between sample data and the probability distribution (, which is supposed to have generated them. The estimation of using an empirically derived distribution is discussed along with specific estimators such as the sample mean, the sample median, and a histogram. Estimation by the method of moments, minimum least squares, and least absolute errors are explained, as are the concepts of bias, mean square error, and sufficiency.
Markov Chain Monte Carlo
Authors: Ekvall Karl Oskar , Jones Galin L. 
Published: November 2019

Abstract

Practically relevant statistical models often give rise to probability distributions that are analytically intractable. Fortunately, we now have a collection of algorithms, known as
Markov chain Monte Carlo (MCMC)
, that has brought many of these models within our computational reach. MCMC is a simulation technique that allows us to make (approximate) draws from complex, high‐dimensional probability distributions. A staggering amount of research has been done on both the theoretical and applied aspects of MCMC. This article does not intend to be a complete overview of MCMC but only hopes to get the reader started in the right direction. To this end, this article begins with a general description of the types of problems that necessitate the use of MCMC. It then introduces the fundamental algorithms and addresses some general implementation issues.

Published: November 2019

AbstractObjectiveTo investigate the association between diet quality and chronic axonal polyneuropathy.MethodsBetween June 2013 and January 2017, among 1650 participants of the Rotterdam Study (median age 69.1 years, 54.2% women), diet quality was quantified based on food frequency questionnaires as a sum score of adherence (yes/no) to 14 components of the Dutch dietary guidelines. Presence of polyneuropathy was determined based on a questionnaire, neurological examination of the legs, and nerve conduction studies. We used logistic regression to associate diet quality with the presence of chronic axonal polyneuropathy and linear regression to associate with sural sensory nerve action potential (SNAP) amplitude in participants without polyneuropathy. Results were adjusted for age, sex, time between measurements, body mass index, blood pressure, diabetes mellitus, smoking, kidney function, and education.ResultsOverall diet quality was not associated with chronic axonal polyneuropathy (odds ratio [OR] = 0.99, 95% confidence interval [CI] 0.88; 1.12, P = 0.842), nor with sural SNAP amplitude in participants without polyneuropathy (difference = 0.01, 95% CI −0.14; 0.15, P = 0.993). Although not surviving multiple testing, a nominally significant association was found between salt intake ≤6 g/day and presence of chronic axonal polyneuropathy (OR = 0.55, 95% CI 0.35; 0.86, P = 0.008).InterpretationWe did not find an association between diet quality and chronic axonal polyneuropathy.
Gas Sensing of NiO‐SCCNT Core–Shell Heterostructures: Optimization by Radial Modulation of the Hole‐Accumulation Layer
Authors: Raza Muhammad Hamid , Movlaee Kaveh , Leonardi Salvatore Gianluca , Barsan Nicolae , Neri Giovanni , Pinna Nicola 
Published: November 2019

AbstractHierarchical core–shell (C–S) heterostructures composed of a NiO shell deposited onto stacked‐cup carbon nanotubes (SCCNTs) are synthesized by atomic layer deposition (ALD). A film of NiO particles (0.80–21.8 nm in thickness) is uniformly deposited onto the inner and outer walls of the SCCNTs. The electrical resistance of the samples is found to increase of many orders of magnitude with the increasing of the NiO thickness. The response of NiO–SCCNT sensors toward low concentrations of acetone and ethanol at 200 °C is studied. The sensing mechanism is based on the modulation of the hole‐accumulation region in the NiO shell layer upon chemisorption of the reducing gas molecules. The electrical conduction mechanism is further studied by the incorporation of an Al2O3 dielectric layer at NiO and SCCNT interfaces. The investigations on NiO–Al2O3–SCCNT, Al2O3–SCCNT, and NiO–SCCNT coaxial heterostructures reveal that the sensing mechanism is strictly related to the NiO shell layer. The remarkable performance of the NiO–SCCNT sensors toward acetone and ethanol benefits from the conformal coating by ALD, large surface area of the SCCNTs, and the optimized p‐NiO shell layer thickness followed by the radial modulation of the space‐charge region.

Published: November 2019

AbstractChloride ion batteries (CIBs) are a promising type of energy storage device due to their high theoretical volumetric energy density and abundant reserves of chlorine‐containing precursors. However, the unsatisfactory cycling performance and structural instability of cathode materials hinder their practical application. In this work, layered double hydroxides (LDHs), which consist of a trimetallic NiVAl hydroxide host matrix and interlayer Cl−, are demonstrated to be high‐performance cathode materials for CIBs. The Ni2V0.9Al0.1‐Cl LDH is capable of delivering a high initial capacity of 312.2 mAh g−1 at 200 mA g−1 and an ultralong life over 1000 cycles (with a capacity higher than 113.8 mAh g−1). Such a long cycling life exceeds that of any reported CIBs. The remarkable Cl−‐storage performance of the Ni2V0.9Al0.1‐Cl LDH is ascribed to the synergetic contributions from Vm+ (high redox activity), Ni2+ (favorable electronic structure), and inactive Al3+ (enhances the structural stability), which is revealed by a comprehensive study that utilizes synchrotron X‐ray absorption near‐edge structure experiments, kinetic investigations, and theoretical calculations. This study provides an effective strategy to achieve superior rechargeable batteries, which are applicable to large‐scale energy storage and power grids.
Well‐Controlled Decomposition of Copper Complex Inks Enabled by Metal Nanowire Networks for Highly Compact, Conductive, and Flexible Copper Films

Published: November 2019

AbstractHighly compact and conductive Cu films are successfully fabricated by introducing mechanically robust and highly conductive metal nanowires (NWs) as fillers and optimizing amine‐based ligands in Cu complex inks. The metal NWs (AgNWs and CuNWs) dispersed in the complex inks provide networks of nucleation sites for the in situ formed Cu particles and thereby control the decomposition of Cu complex inks at low temperatures to realize Cu films with high uniformity and integrality. The high affinity between metal NWs and the in situ formed Cu element enables the growth of Cu particles along the metal NWs to create a compact structure. Besides, the amine‐based ligands such as 2‐amino‐2‐methyl‐1‐propanol (AMP), 2‐ethylhexylamine (Ethy), and hexylamine (Hexy) are varied to adjust the size of Cu particles and further improve the microstructure and conductivity of the sintered Cu films. The Cu‐Ethy complex/metal NW inks sintered at 140 °C exhibit the lowest resistivity of 14.9 µΩ cm, which is about one‐third that fabricated from the pure Cu‐AMP complex inks. The flexible light‐emitting diode circuits and V‐shaped dipole antennas prepared from the Cu complex/metal NW inks have excellent performance due to their outstanding conductivity and flexibility, showing great potential in the fabrication of cost‐effective, flexible printed electronic devices.
Postdeposition Ligand Exchange Allows Tuning the Transport Properties of Large‐Scale CuInSe2 Quantum Dot Solids
Authors: Gorris Friederieke E. S. , Deffner Michael , Priyadarshi Shekhar , Klinke Christian , Weller Horst , Lange Holger 
Published: November 2019

AbstractColloidal quantum dots assembled into quantum dot solids usually suffer from poor conductivity. The most common charge transport mechanism through the solid is hopping transport where the hopping probability depends on the barrier type (stabilizing/connecting ligand molecule) and the interparticle distance. It is demonstrated that the electronic structure of the ligand molecule strongly alters the transport behavior through CuInSe2 quantum dot solids. Transport measurements and optical‐pump terahertz‐probe experiments after a ligand exchange to fully conjugated molecules show an increase of the conductivity by orders of magnitude, as well as a change of the hopping transport mechanism. This change is not due to a reduced interparticle distance, but the electronic structure: the obtained frequency‐dependent complex conductivities point toward an efficient hole transport enabled by an alignment of the quantum dot valence bands and ligand states.
Efficiency Enhancement of All‐Solution‐Processed Inverted‐Structure Green Quantum Dot Light‐Emitting Diodes Via Partial Ligand Exchange with Thiophenol Derivatives Having Negative Dipole Moment
Authors: Moon Hyungsuk , Chae Heeyeop 
Published: November 2019

AbstractThiophenol derivatives having a negative dipole moment such as thiophenol (TP), 4‐methylthiophenol (4‐MTP), and 4‐(dimethylamino)thiophenol (4‐DMATP) are incorporated into quantum dots (QDs) and the efficiency of all‐solution‐processed inverted‐structure quantum dot light‐emitting diodes (QLEDs) is enhanced. The negative dipole moments of TP, 4‐MTP, and 4‐DMATP are attributed to the enhancement of the efficiency of the QLEDs. The valence band maximum (VBM) of the QDs is upshifted, and the energy gap between the VBM and the highest molecular orbital level of the hole transport layer is reduced to −0.16 from 0.46 eV by the negative dipole moment of thiophenol derivatives. The electron and hole transport of the QDs are accelerated, and charge balance is achieved at 5 V with a reduction of 1.25 V by the thiophenol derivatives. The QLEDs with 4‐DMATP exhibit a maximum luminance of 106 400 cd m−2, a maximum current efficiency of 98.2 cd A−1, and an external quantum efficiency (EQE) of 24.8%. The EQE of 24.8% is the highest value reported thus far for all‐solution‐processed inverted‐structure single‐device QLEDs, to the best of knowledge. Improvement by factors of 2.99, 1.57, and 1.54 are achieved in the maximum luminescence, maximum current efficiency, and EQE respectively, compared with a QLED with OA ligands.
