Published: August 2017

Takotsubo cardiomyopathy (TTC) is a recently identified transient cardiomyopathy that is usually associated with emotional or physical stress. Catecholamine surge appears to be central to the mechanism of TTC. TTC in the setting of anaphylaxis is rare. We present a case of a 58-year-old female was referred from an outside hospital after being diagnosed with anaphylaxis. She received 0.3 mg epinephrine intramuscularly and 1 mg intravenously. Upon admission to our hospital, she was complaining of chest pain. EKG done in the outside hospital showed ST elevations in the anterior leads but the EKG done at our hospital was normal. She had to be intubated in view of impending airway obstruction. She was subsequently started on epinephrine infusion in the intensive care unit for hypotension. She was found to have elevated troponins that trended up. An echocardiogram performed on day 3 revealed a left ventricular ejection fraction of 25% and apical hypokinesis suggestive of TTC. Cardiac catheterization was initially deferred in view of a history of dye allergy. A nuclear stress test was done instead that revealed reversible ischemia in anteroseptal regions. Cardiac catheterization was performed eventually with pre-medication that showed a near-normal coronary circulation. A repeat echocardiogram performed 6 weeks after discharge showed normal systolic function.
RABELAIS AU PLURIEL

Ce texte a pour point de départ une expérience partagée, entre 1966 et 1969, par
l’auteur de l’article et André Belleau lui-même : la fréquentation des cours de philologie
faisant partie du programme de lettres à l’Université de Montréal, ainsi que du cours
consacré à François Rabelais par le professeur invité Michaël Baraz. L’hypothèse développée
est que la valorisation du multiple et de l’hétérogène chez Belleau doit beaucoup à ces
enseignements, mais ne va pas sans problème. Bien que les travaux de Bakhtine, encore peu
connus à l’époque, soient venus par la suite étayer la lecture festive et carnavalesque de
la multiplicité rabelaisienne que propose Belleau, la possibilité que le pluriel confine au
non-sens ne cesse de poindre. Si Baraz a recours à des philosophes, et principalement à
Spinoza, pour affronter le problème du pluriel, Belleau pense que le multiple se réalise
dans une éthique du mouvement et que c’est le langage, dans sa mouvance et son dynamisme
historique, qui est par excellence son lieu d’accomplissement. Par là se marque chez lui
l’héritage de la philologie, qui saisit la langue comme un processus contingent et comme le
produit d’une multitude de faits liés à la mobilité des peuples et à l’interaction des
cultures.

Usando muestras de sedimentos del testigo GeoB 3388-1 de la dorsal de Iquique, norte de Chile (25ºS), reportamos la última fecha de aparición (UFA) de siete especies del grupo extinto Stilostomella. La extinción de Stilostomella, el más grande recambio de foraminíferos bentónicos de aguas profundas, ha sido documentada en trabajos previos para el Pacífico sudoriental (PSO) y es ampliada por nuestro trabajo como evidencia cualitativa de este evento. La extinción de Stilostomella involucra la desaparición de especies elongadas de las familias Nodosariidae, Pleurostomellidae y Stilostomellidae. La UFA de Myllostomella sp. Hayward 2002 (518 cm, 0.79 ma) del testigo GeoB 3388-1 es similar a un registro previo para el PSO, pero es anterior a reportes a nivel mundial (0.65–0.57 ma), por lo que se concluye que el momento de extinción en el PSO fue diferente al ocurrido en los océanos Atlántico y Pacífico sudoccidental. La UFA de Myllostomella sp. coincide con el incremento en δ13C y CaCO3, sugiriendo cambios en la disponibilidad de nutrientes y la circulación del PSO durante la Transición del Pleistoceno Medio. El mecanismo causal preciso de la extinción del grupo Stilostomella (enfriamiento, incremento en la oxigenación de las aguas de fondo, cambios en el suministro de alimento) permanece sin resolverse.

Punta Banda Estuary, located within Todos Santos Bay, on the northwest coast of the Baja California Peninsula, is separated from the bay by a single sandbar, approximately 8 km long. From 1972 to 2003 this sandbar showed a longitudinal net growth of 420 m, which decreased the width of the estuary mouth by more than 400 m. Despite the bar's rapid growth it has been suggested that the estuary mouth remains open because in spring, summer and autumn the longshore sand transport is northeastward, but during winter the longshore sand transport should be toward the southwest, away from the mouth, establishing a balance between the amount of sediment transported both ways. In this study we analyze wave data acquired from November 2004 to March 2005 on the bay side of the sandbar, and for the first time provide the magnitude and direction of the longshore sand transport during winter. The results show that during this season the dominant waves approach the bay from the west-northwest and the sandbar from the west, inducing a net longshore sand transport of 817 m3 day–1 to the northeast. This result contradicts the hypothesis of a longshore sand transport balance, and shows that throughout a typical year the net longshore sand transport is to the northeast. The fact that the estuary mouth has not closed up should be attributed to other causes, such as extraordinary amounts of rain during the rainy season or inequalities between the ebb and flood tidal current velocities to the estuary.
Analysis framework for systematically studying ionospheric response to impulsive events from below
Authors: Haaser Robert A. , Lay Erin H. , Junor William 
Published: August 2017

AbstractImpulsive phenomena in the Earth's atmosphere produce acoustic and gravity waves which perturb the ionosphere. Such perturbations are often measured using total electron content fluctuations (TEC), derived from ground‐based Global Positioning System data. Using TEC data from the Japanese GEONET ground network after the Tōhoku earthquake on 11 March 2011, we demonstrate capabilities of a new framework of methodologies for analyzing ionospheric perturbations. The framework consists of several new techniques: calculating velocity along a single direction to reduce error due to anisotropic propagation, producing normalized bidirectional band‐pass spectra that preserve relative timing between various frequencies and allowing a more systematic determination of broadband pulses, and utilizing a wavelet‐based technique that considers instantaneous wave phase changes, rather than best fit time differences, to evaluate wave characteristics (speed, direction, and wavelength) within spectral ranges of interest. Using these techniques together decreases subjectivity and reduces errors in attributing fluctuations to given sources. In validating this framework using the Tōhoku case, we consistently identify three kinds of waves: a broad‐band pulse (speed: >2000 m/s, max range: >1400 km) arriving in the ionosphere 10–15 min after the quake, acoustic waves following the pulse (period: 3–5 min, speed: 700–1000 m/s, max range: <500 km), and gravity waves (period: 10–15 min, speed: 150–500 m/s, max range: >1400 km) propagating away from the epicenter, consistent with theory and demonstrated in previous studies. This framework also can be applied to other impulsive events in the atmosphere that are more difficult to detect and attribute to sources.
Record temperature streak bears anthropogenic fingerprint

Published: August 2017

AbstractWe use a previously developed semiempirical approach to assess the likelihood of the sequence of consecutive record‐breaking temperatures in 2014–2016. This approach combines information from historical temperature data and state‐of‐the‐art historical climate model simulations from the Coupled Model Intercomparison Project Phase 5 (CMIP5). We find that this sequence of record‐breaking temperatures had a negligible (<0.03%) likelihood of occurrence in the absence of anthropogenic warming. It was still a rare but not implausible event (roughly 1–3% likelihood) taking anthropogenic warming into effect. The probability that three consecutive records would have been observed at some point since 2000 is estimated as ~30–50% given anthropogenic warming and <0.7% in its absence. The likelihood of observing the specific level of record warmth recorded during 2016 is no more than ~one‐in‐a‐million neglecting anthropogenic warming, but as high as 27%, i.e., a nearly one‐in‐three chance of occurrence taking anthropogenic warming into account.
Partitioning of oblique convergence coupled to the fault locking behavior of fold‐and‐thrust belts: Evidence from the Qilian Shan, northeastern Tibetan Plateau

Published: August 2017

AbstractOblique plate convergence is common, but it is not clear how the obliquity is achieved by continental fold‐and‐thrust belts. We address this problem in the Qilian Shan, northeastern Tibetan Plateau, using fieldwork observations, geomorphic analysis, and elastic dislocation modeling of published geodetic data. A thrust dips SSW from the northern range front and underlies steeper thrusts in the interior. Cenozoic thrust‐related shortening across the Qilian Shan is ~155–175 km, based on two transects. Elastic dislocation modeling indicates that horizontal strain in the interseismic period is consistent with oblique slip on a single low‐angle detachment thrust below ~26 km depth, dipping SSW at ~17°. We suggest that this detachment is located above North China Block crust, originally underthrust during Paleozoic orogeny. Horizontal shear strain is localized directly above the updip limit of creep on the detachment and is coincident with the left‐lateral Haiyuan Fault. This configuration implies that oblique slip on the detachment below seismogenic depths is partitioned in the shallow crust onto separate strike‐slip and thrust faults. This is consistent with strain partitioning in oceanic subduction zones but has not previously been found by dislocation models of continental interiors. The marginal, strike‐slip, Altyn Tagh Fault influences thrusting within the Qilian Shan for 100–200 km from the fault but does not control the regional structure, where Paleozoic basement faults have been reactivated. The Qilian Shan resembles the main Tibetan Plateau in nascent form: active thrusts are marginal to an interior that is developing plateau characteristics, involving low relief, and low seismicity.
The ~2730 Ma onset of the Neoarchean Yilgarn Orogeny

Published: August 2017

AbstractThe timing of the onset of an orogeny is commonly constrained indirectly, because early orogenic structures are rarely exposed or are overprinted. Establishing the onset of an Archean orogeny is considerably more challenging, because of the more fragmented geological record and the general lack of consensus about Archean geodynamics. We combine existing tectonostratigraphic data with new structural and geophysical data sets to establish the onset of the Neoarchean Yilgarn Orogeny (Yilgarn Craton, Western Australia). We show that the surface of the ~2960–2750 Ma deep‐marine Yilgarn greenstone sequence was uplifted, eroded, and unconformably overlain by an ~2730 Ma, syntectonic clastic sequence, deposited in shallow marine to subaerial conditions, and derived from the erosion of the underlying greenstones. This ~2730 Ma regional unconformity predates the oldest known Yilgarn structures; therefore, its tectonic significance is so far unknown. At around the same time, at deeper crustal levels, the ~2728 Ma Yarraquin pluton was being emplaced along an active, large‐scale shear zone network. Our mesostructural and microstructural analysis shows that the bulk of the fabric in the granite and its country rocks developed during pluton emplacement and was largely assisted by magma‐present shearing. Overall, these structures reflect an important event of synemplacement crustal shortening. The regional unconformity and the syndeformational emplacement of the Yarraquin pluton are both expressions of an ~2730 Ma regional deformation event associated with significant crustal thickening, marking the onset of the Neoarchean Yilgarn Orogeny.
Controls of inherited lithospheric heterogeneity on rift linkage: Numerical and analog models of interaction between the Kenyan and Ethiopian rifts across the Turkana depression
Authors: Brune Sascha , Corti Giacomo , Ranalli Giorgio 
Published: August 2017

AbstractInherited rheological structures in the lithosphere are expected to have large impact on the architecture of continental rifts. The Turkana depression in the East African Rift connects the Main Ethiopian Rift to the north with the Kenya rift in the south. This region is characterized by a NW‐SE trending band of thinned crust inherited from a Mesozoic rifting event, which is cutting the present‐day N‐S rift trend at high angle. In striking contrast to the narrow rifts in Ethiopia and Kenya, extension in the Turkana region is accommodated in subparallel deformation domains that are laterally distributed over several hundred kilometers. We present both analog experiments and numerical models that reproduce the along‐axis transition from narrow rifting in Ethiopia and Kenya to a distributed deformation within the Turkana depression. Similarly to natural observations, our models show that the Ethiopian and Kenyan rifts bend away from each other within the Turkana region, thus forming a right‐lateral step over and avoiding a direct link to form a continuous N‐S depression. The models reveal five potential types of rift linkage across the preexisting basin: three types where rifts bend away from the inherited structure connecting via a (1) wide or (2) narrow rift or by (3) forming a rotating microplate, (4) a type where rifts bend towards it, and (5) straight rift linkage. The fact that linkage type 1 is realized in the Turkana region provides new insights on the rheological configuration of the Mesozoic rift system at the onset of the recent rift episode.
Nepenthes Inspired Design of Self‐Repairing Omniphobic Slippery Liquid Infused Porous Surface (SLIPS) by Femtosecond Laser Direct Writing

AbstractIn this Communication, femtosecond laser is first used to successfully fabricate a slippery liquid infused porous surface (SLIPS). A kind of 3D porous network microstructure can be directly created on polyamide‐6 (PA6) substrate by a one‐step femtosecond laser direct writing method. The preparation process of SLIPS mainly includes three steps: femtosecond laser ablation, fluoroalkyl layer modification, and infusion of lubricating liquid. The porous layer and the substrate layer of this as‐prepared SLIPS are inherent one material. Such SLIPS has many advantages over the most reported SLIPS fabricated based on “deposition/coating” methods whose porous layers are foreign materials against the substrates. A broad range of liquids including water, hexadecane, lake water, ink, glycerol, coffee, milk, egg white, and egg yolk can easily slide down the 10° tilted SLIPS, revealing that the resultant SLIPS has excellent liquid‐repellent ability. Even though the SLIPS suffers from heavily physical damage, the surface can rapidly self‐repair without any additional treatment and obtain slippery property again. The developed SLIPS promises to contribute to the achievement of omniphobic materials in self‐cleaning, antifouling, biomedical devices, and fuel transport.
Laser Forming for Complex 3D Folding
Authors: Lazarus Nathan , Smith Gabriel L. 
Published: August 2017

AbstractLaser heating to generate plastic strains for controlled bending, known as laser forming, is a promising technique for creating 3D structures based on origami‐inspired principles. Here, for the first time, laser cutting and forming are used to go from flat unpatterned metal sheet to final folded part, including up and down folds, all without manual handling. Folding direction is controlled by adjusting laser travel speed to create either a lateral or a vertical thermal gradient in the workpiece. Numerical modeling followed by experimental verification is used to determine the transition point between bending toward and away from the laser, followed by demonstration of a variety of complex 3D folded parts. Using this approach, laser forming is then used to precisely align two components, demonstrating the positioning of an optical reflector to guide the laser and pattern a portion of the sheeting originally inaccessible on the underside. All work here is done with a commercially available 20 W marking laser without modification.
Conducting melt blending of polystyrene and EVA copolymer with carbon nanotube assisted by phosphonium‐based ionic liquid

Published: August 2017

ABSTRACTConducting composite materials, with electrical percolation threshold as low as 0.05–0.08 wt %, are prepared by incorporating multiwall carbon nanotube (CNT) in melt‐mixed co‐continuous polystyrene (PS)/ethylene‐vinyl acetate (EVA) copolymer (70:30 wt/wt) blend. CNT is found to be preferentially localized within the EVA phase, characterizing a double percolation phenomenon, which accounts for outstanding electrical conductivity (around 0.5 S/m with the addition of 1 wt % of CNT). The noncovalent functionalization of CNT with alkylphosphonium‐based ionic liquid results in composites with improved electrical conductivity (2.5 S/m with 1 wt % of CNT) and better electromagnetic interference shielding effectiveness. Both nonfunctionalized CNT (n‐CNT) or CNT with alkylphosphonium‐based ionic liquid contribute for a refinement of the co‐continuous structure, as indicated by scanning electron microscopy. The dispersion of CNTs and their physical networked structure within the polymer matrix are suggested by transmission electron microscopy and melt rheological experiments. © 2017 Wiley Periodicals, Inc.

Adhesion control of interface between cellulose and polypropylene by vapor‐phase assisted surface copolymerization
Authors: Gomi Satoshi , Nishida Haruo 
Published: August 2017

ABSTRACTIn order to achieve the effective interface bonding between biomass microfiller and commodity plastics, consecutive copolymerization of hydrophilic acrylic acid (AA) and hydrophobic butyl acrylate (BA) using vapor‐phase assisted surface polymerization (VASP) technology was applied to prepare microcomposites consisting of cellulose microcrystal (CμC) and polypropylene (PP). After the copolymerization by VASP, CμC surfaces were covered by accumulated polymers: P(AA‐co‐BA) including block‐type copolymer and homopolymers of 6.2–25.3 wt % versus CμC. Although structures of the products were unspecified, it was expected to be mixtures of block copolymers and homopolymers. Subsequently prepared P(AA‐co‐BA) on CμC/PP (5/95 wt/wt) composites expressed a superior mechanical toughness, which had increased threefold when compared to intact CμC/PP composite. This increase in toughness was mainly based on an increase in elongation rate, reflecting improvement of the adhesion strength at the interface between CμC surface and PP. The trace amounts: 0.31 wt % of accumulated P(AA‐co‐BA) on CμC surface must function as an effective adhesive/compatibilizer at the interface. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

AbstractAimThe prognostic value of coronary artery dominance pattern in patients with chronic total occlusions (CTO) is unknown. The aim of this study was to assess the influence of coronary vessel dominance on short and long‐term outcomes in patients undergoing percutaneous coronary intervention (PCI) for CTO.Methods and resultsOur study population consisted of 2002 consecutive patients (17% females, mean age 65.2 ± 10.7 years) who underwent PCI of at least one coronary CTO lesion at our center between 01/2005 and 12/2013. Based on the origin of the posterior descending coronary artery, coronary circulation was categorised into left, right, and balanced coronary dominance. Right coronary dominance (RD) was present in 88% (n = 1759), left coronary dominance (LD) in 7% (n = 136), and balanced coronary dominance (BD) in 5% (n = 107) of the study population. After a median follow‐up duration of 2.6 years [interquartile range 1.1–3.1 years] all‐cause mortality was significantly higher in patients with LD as compared with RD and BD (log rank = 0.001). Accordingly, the presence of a LD system was identified as a significant predictor for all‐cause mortality (adjusted HR 1.7, 95% CI: 1.2‐2.6, P = .007) and major adverse cardiac events (MACE) (adjusted HR 1.4, 95% CI: 1.1‐1.8, P = 0.02).ConclusionOur data suggest that LD is an independent predictor of increased all‐cause death and MACE in patients with CTO. Therefore, assessment of coronary vessel dominance by angiography may contribute to risk stratification in these patients.
Anion‐π Catalysts with Axial Chirality
Authors: Wang Chao , Matile Stefan 
Published: August 2017

AbstractThe idea of anion‐π catalysis is to stabilize anionic transition states by anion‐π interactions on aromatic surfaces. For asymmetric anion‐π catalysis, π‐acidic surfaces have been surrounded with stereogenic centers. This manuscript introduces the first anion‐π catalysts that operate with axial chirality. Bifunctional catalysts with tertiary amine bases next to π‐acidic naphthalenediimide planes are equipped with a bulky aromatic substituent in the imide position to produce separable atropisomers. The addition of malonic acid half thioesters to enolate acceptors is used for evaluation. In the presence of a chiral axis, the selective acceleration of the disfavored but relevant enolate addition was much better than with point chirality, and enantioselectivity could be observed for the first time for this reaction with small‐molecule anion‐π catalysts. Enantioselectivity increased with the π acidity of the π surface, whereas the addition of stereogenic centers around the aromatic plane did not cause further improvements. These results identify axial chirality of the active aromatic plane generated by atropisomerism as an attractive strategy for asymmetric anion‐π catalysis.
