Oakland Bay Bridge – Rückbau der 504′‐Brückenfelder
Authors: Brunold Urs , Joss Beat 
Published: December 2017

AbstractDer 3,4 km lange östliche Teil der um 1936 in Verkehr gesetzten Brücke zwischen San Francisco und Oakland wurde 2013 nach mehreren Jahren Bauzeit durch eine neue, nach modernem Stand der Technik erbauten Brücke ersetzt. Die drei Hauptabschnitte der historischen Brückenkonstruktion wurden im Nachgang zum Rückbau freigegeben.Für den Rückbau der fünf 504′ (154 m) langen und ca. 1 680 t schweren Brückenfelder wurde Litzenhebertechnik angewandt. Die Felder wurden in fünf Vorgängen von ihren ursprünglichen Lagen auf Lastkähne abgesenkt. Mittels der Lastkähne wurden dann diese Brückenfelder in einen Hafenbereich verbracht, wo diese zerlegt wurden und der Stahl anschließend einem Recyclingzyklus zufloss.Einflussgrößen wie der genietete starre Brückenkörper, Verankerung von Reaktionslasten unter erschwerten Platzverhältnissen, Arbeiten über Wasser, eingeschränkte Montagemittel, Zeitpläne, Wettereinflüsse usw. bestimmten Ausführung und Arbeitsplan.Für die Absenkung der Brückenfelder wurde ein computergesteuertes Litzenhebersystem eingesetzt, welches an den vier Hauptauflagepunkten der jeweiligen Brückenfelder aufgebaut wurde. Gleichzeitig wurden zusätzliche Litzenheber zur notwendigen Rückverankerung eingesetzt. Um den Umbau für die jeweils nächste Absenkung zu vereinfachen, wurden die Absenkheber zusammen mit einer Vorrichtung zum Auf‐ und Abrollen der Litzen auf demontierbaren Plattformen aufgebaut.Die eingesetzte Technik trug dazu bei, den für die Arbeiten vorgesehenen Zeitrahmen von 14 auf acht Monate zu verkürzen.

AbstractThe differences between the K indices derived with the FMI Method (V1.0) and the Kp indices were analyzed, four problems were found such as discrete K1 and K8 among different observatories, K indices about 0.5 larger than Kp indices, wrong SR on several individual days, steps between SR and its next day SR. In order to resolve the above mentioned problems, we improved the FMI method of deriving K indices. The K indices derived with the improved FMI Method were compared with the Kp indices, the K indices derived with the original FMI Method and other methods as well, it was found that the K indices derived with the improved FMI Method were closer to the Kp indices and the K indices derived with other methods than the original FMI Method.

Published: December 2017

AbstractThe lithosphere‐asthenosphere boundary (LAB) is a seismic discontinuity with negative velocity contrast in the upper mantle. Seismic detections of the LAB in subduction zone region are helpful to understand the interaction between the lithosphere and asthenosphere and the geodynamic process associated with the slab subduction. In this paper, the vertical broadband waveforms are collected from four deep earthquakes occurred from 2006 to 2012 beneath the central South America area. The seismic waveforms are processed with the linear slant stack method to get the vespagrams in the relative travel‐time vs. slowness domain, and the sP precursors reflected at the bottom of the LAB (sLABP) are successfully extracted. Based on the one‐dimensional modified velocity model (IASP91‐SA), the horizontal distribution for the six sLABP reflecting points is obtained and divided into the western part (I) and the eastern part (II). In the part I, the LAB depth ranges between 60 km and 63 km, with the average depth of 61 km and the topography of 3 km; in the part II, the LAB depth ranges between 78 km and 82 km, with the average depth of 80 km and the topography of 4 km. Our results reveal the increasing LAB depths from west to east in the central South America area, and the trend may possibly represent the reformation differences of the continental lithosphere. We infer that near the trench, the continental lithosphere may be subjected to the stronger erosion for the higher degree of partial melting and more fertile melts in the asthenosphere; while far from the trench, the continental lithosphere may be subjected to the weaker erosion for the lower degree of partial melting and less fertile melts in the asthenosphere.

Published: December 2017

AbstractCrustal lithology transformation, lithological variations with depth and tectonic deformation in the Tibetan plateau are the key to explore the crustal thickening and material motion in this region. Located in the central plateau, the Bayan Har block has a vast geographical territory. To make a further study on the fine crustal structure in the central and eastern Bayan Har block, we conduct a comprehensive analysis of the deep seismic wide‐angle reflection/refraction phase data of different areas of this block, and then perform detailed simulation calculation of the travel‐time and amplitude characteristics of different phases using the synthetic reflectivity seismograms. The results indicate that the thickness of the Bayan Har block varies from 50 km to 60 km, increasing westward gradually. The average velocity in the crystalline crust is 6.07∼6.18 km·s−1, which is obviously reduced, and there are several strong reflection interfaces in the crust, which differ in different regions. In the east, the Zoigě basin has a low velocity within the crust and a clear crust‐mantle boundary. In the central part, a high velocity structure (6.8 km·s−1) is present beneath the Yushu‐Madoi segment with an unclear crust‐mantle boundary, i.e. the Moho interface transformed into a high velocity gradient layer with a thickness of 2∼4 km. These characteristics indicate the discrepancy of crustal thickening and lithology transformation within the Bayan Har block. Multi‐group strong reflections in the crust and the low apparent velocity indicate the shattered, low‐velocity, weakened, creeping, and possibly decoupling structures in the crust. High apparent velocity phase in the lower crust displays that there may be stable original crust residual or material exchanging with the upper mantle under the background of the crustal thickening and transformation in the Tibetan plateau. The diversity of different areas within the Bayan Har block involves the crustal thickening, lithology structure, crystalline basement and crust‐mantle boundary nature transformation, which can provide new insights into the understanding of the crustal deformation and dynamical process in the Tibetan plateau.

AbstractInhibition of Bordetella pertussis adenylate cyclase toxin (ACT) and Bacillus anthracis edema factor (EF), key virulence factors with adenylate cyclase activity, represents a potential method for treating or preventing toxemia related to whooping cough and anthrax, respectively. Novel α‐branched acyclic nucleoside phosphonates (ANPs) having a hemiaminal ether moiety were synthesized as potential inhibitors of bacterial adenylate cyclases. ANPs prepared as bisamidates were not cytotoxic, but did not exhibit any profound activity (IC50>10 μm) toward ACT in J774A.1 macrophages. The apparent lack of activity of the bisamidates is speculated to be due to the inefficient formation of the biologically active species (ANPpp) in the cells. Conversely, two 5‐haloanthraniloyl‐substituted ANPs in the form of diphosphates were shown to be potent ACT and EF inhibitors with IC50 values ranging from 55 to 362 nm.

AbstractCarbon is usually used as cathode material for Li–O2 batteries. However, the discharge product, such as Li2O2 and LiO2, could react with carbon to form an insulating lithium carbonate layer, resulting in cathode passivation and capacity fading. To solve this problem, the development of non‐carbon cathodes is highly desirable. Herein, we successfully synthesized MnCo2O4 (MCO) nanoparticles anchored on porous MoO2 nanosheets that are grown on Ni foam (current collector) (MCO/MoO2@Ni), acting as a carbon‐ and binder‐free cathode for Li–O2 batteries, in an attempt to improve the electrical conductivity, electrocatalytic activity, and durability. This MCO/MoO2@Ni electrode delivers excellent cyclability (more than 400 cycles) and rate performance (voltage gap of 0.75 V at 5000 mA g−1). Notably, the battery with this electrode exhibits a high energy efficiency (higher than 85 %). The advanced electrochemical performance of MCO/MoO2@Ni can be attributed to its high electrical conductivity, excellent stability, and outstanding electrocatalytic activity. This work offers a new strategy to fabricate high‐performance Li–O2 batteries with non‐carbon cathode materials.

Published: December 2017

AbstractLead halide perovskites have recently attracted attention due to their outstanding photoelectric properties. Hence, perovskite‐based optoelectronic devices are widely studied. Herein, a simple solution‐based one‐step anti‐solvent method to produce well‐controlled and uniform CH3NH3PbBr3‐based micro‐devices is reported. It is confirmed that the size and mode numbers of the self‐assembled microdisk cavities can be well controlled by modifying the size of the SiO2 microdisks on the substrate or changing the concentration of the perovskite precursor. With this simple and robust method, the produced CH3NH3PbBr3 microdisk arrays are extremely uniform in both their size distribution and emission spectra. Moreover, a perovskite photodetector array with fast rise (<8.3 ms) and decay (<8.3 ms) times was fabricated by periodically patterning the substrate. Based on the high controllability and high reproducibility of the patterned CH3NH3PbBr3 microdisk arrays, this cost‐effective and mass‐manufacturable approach significantly increases the production yield of lead halide perovskite microdevices and boosts their ability to be used in practical applications.

Published: December 2017

PurposeThe sentinel lymph node (SLN) biopsy technique has highly evolved during the last 20 yr. Consequently, the intraoperative use of Gamma Probes (GPs) for SLN mapping is increased. This preliminary study evaluates a novel directional GP prototype. This proof‐of‐concept prototype is designed to identify the direction of radiopharmaceuticals uptakes, by combining the information from multiple detectors. The purpose of this work is to develop a tool able to effectively guide the surgeon reducing the surgery time.MethodsThe proposed prototype consists of three CsI(Tl) scintillation crystals, each coupled with an S10931 silicon photomultiplier (Hamamatsu Photonics K.K., Hamamatsu, JP). The three detectors lie on the same plane with an angle of 30° between them. The central detector is placed as in a common GP, so it can be used to pinpoint the target tissue. Meanwhile, the lateral sensors provide a broader view of the surgical field. A dedicated data acquisition system digitizes and processes the signals from the front‐end electronics. Finally, an embedded system, based on ARM processor, calculates and displays the acquired count rates. In order to assess the prototype behavior, the isosensitivity curves for the three detectors were measured. Meanwhile, for the central one, the main quality criteria measurements were also performed (i.e., sensitivity, radial sensitivity, and spatial resolution).ResultsFor the central detector, the measured sensitivity at the tip of the probe is better than 5 cps/kBq. The full width at half maximum (FWHM) of the radial sensitivity is less than 30° and the FWHM of the lateral sensitivity (spatial resolution) is about 7.2 mm. The central detector measured isosensitivity distribution shows a narrow profile in agreement with the spatial resolution measured. On the contrary, the two lateral detectors exhibit widespread isosensitivity distributions that mean a larger field of view. The system had shown satisfactory performance and reliability, meeting the minimal requirements of gamma probe systems.ConclusionsThe prototype presented in this paper allows a rapid localization by the use of the whole system, while the sole central detector can be used to pinpoint the target source. This device, unlike common GPs, allows localizing simultaneously different areas of radiopharmaceuticals uptake, thus precisely guiding the surgeon to the region of interest. These preliminary results encourage to develop a further prototype for intraoperative validation.

Published: December 2017

AbstractThis article proposes a new synthesis of amorphous silica‐alumina (ASA) supported Ni catalyst using hydrothermal synthesis method by the assistant of cis‐9‐octadecenylamine. Cis‐9‐octadecenylamine, as a coordination agent and surfactant, could form Ni‐cis‐9‐octadecenylamine complex with nickel salt under hydrothermal condition, which boosts the metal dispersion. Characterization results by N2 adsorption‐desorption shows that the as‐prepared catalyst is provided with enhanced porosity, especially mesoporous and by XRD, TEM and H2‐TPR display that the resulting Ni particles are very small and uniform. The ASA supported Ni catalyst proves to be highly efficient and stable in naphthalene hydrogenation, and gives 100% conversion and more than 99% selectivity to decalin with an extremely wide activity window at 180∼280 °C, which is superior to its counterparts prepared via traditional impregnation method.

Abstract
The differential expression of two closelyassociated cyclooxygenase isozymes, COX-1 and COX-2, exhibited functions beyond eicosanoid metabolism. We hypothesized that COX-1 or COX-2 knockout lung fibroblasts may display altered protein profiles which may allow us to further differentiate the functional roles of these isozymes at the molecular level. Proteomic analysis shows constitutive production of macrophage migration inhibitory factor (MIF) in lung fibroblasts derived from COX-2−/− but not wild-type (WT) or COX-1−/− mice. MIF was spontaneously released in high levels into the extracellular milieu of COX2−/− fibroblasts seemingly from the preformed intracellular stores, with no change in the basal gene expression of MIF. The secretion and regulation of MIF in COX-2−/− was “prostaglandin-independent.” GO analysis showed that concurrent with upregulation of MIF, there is a significant surge in expression of genes related to fibroblast growth, FK506 binding proteins, and isomerase activity in COX-2−/− cells. Furthermore, COX-2−/− fibroblasts also exhibit a significant increase in transcriptional activity of various regulators, antagonists, and co-modulators of p53, as well as in the expression of oncogenes and related transcripts. Integrative Oncogenomics Cancer Browser (IntroGen) analysis shows downregulation of COX-2 and amplification of MIF and/or p53 activity during development of glioblastomas, ependymoma, and colon adenomas. These data indicate the functional role of the MIF-COX-p53 axis in inflammation and cancer at the genomic and proteomic levels in COX-2-ablated cells. This systematic analysis not only shows the proinflammatory state but also unveils a molecular signature of a pro-oncogenic state of COX-1 in COX-2 ablated cells.
Is there a missing factor? A canonical correlation approach to factor models
Authors: Ahn Seung C. , Dieckmann Stephan , Perez M. Fabricio 
Published: December 2017

AbstractA common question in asset pricing research is if a finite set of observable variables can completely capture the systematic or common variations in a large number of response variables. This paper provides a new approach to answer this question. A novelty is that common factors are extracted using canonical relations between response variables and observable factors. We show how these factors in combination with tests for the number of factors can be used to evaluate if a given set of macroeconomic and financial variables is sufficient to capture all the systematic variation in the response variables. We illustrate the usefulness of our methods by analyzing the systematic determinants of credit spreads of U.S. corporate bonds.
A Measurement Model for Dignity, Face, and Honor Cultural Norms

Published: December 2017

ABSTRACTIn this work we develop and validate a model measuring norms that distinguish three types of culture: dignity, face, and honor (Leung & Cohen, 2011). Our motivation is to produce empirical evidence for this new cultural framework and use the framework to explain cultural differences in interdependent social interactions such as negotiation. In two studies, we establish the content validity, construct validity, predictive validity, and measurement invariance of this measurement model. In Study 1, we present the model's three-factor structure and situate the constructs of dignity, face, and honor in a nomological network of cultural constructs. In Study 2, which uses a sample of participants from 26 cultures, we show that the measurement model discriminates among people from the three cultural regions corresponding to the dignity, face, and honor framework. In particular, we report differences between face and honor cultures, which are not distinguished in other cultural frameworks (e.g., Hofstede, 1980). We also show that the measurement model accounts for cultural differences in norms for use of negotiation strategy.
Multisensory control of ingestive movements and the myth of food addiction in obesity
Authors: Booth David A. 
Published: December 2017

AbstractSome individuals have a neurogenetic vulnerability to developing strong facilitation of ingestive movements by learned configurations of biosocial stimuli. Condemning food as addictive is mere polemic, ignoring the contextualised sensory control of the mastication of each mouthful. To beat obesity, the least fattening of widely recognised eating patterns needs to be measured and supported.
Infant orofacial movements: Inputs, if not outputs, of early imitative ability?
Authors: O'Sullivan Eoin P. , Caldwell Christine A. 
Published: December 2017

AbstractAccording to Keven & Akins (K&A), infant orofacial gestures may not reflect imitative responses. Here, we emphasise that these actions nonetheless represent a significant feature of the infant's early sensorimotor experience, and therefore may play a key role in the development of imitative capacities. We discuss how the ideas proposed in the target article could contribute substantially to experiential accounts of imitation.
Beyond neonatal imitation: Aerodigestive stereotypies, speech development, and social interaction in the extended perinatal period
Authors: Keven Nazim , Akins Kathleen A. 
Published: December 2017

AbstractIn our target article, we argued that the positive results of neonatal imitation are likely to be by-products of normal aerodigestive development. Our hypothesis elicited various responses on the role of social interaction in infancy, the methodological issues about imitation experiments, and the relation between the aerodigestive theory and the development of speech. Here we respond to the commentaries.
Parental work characteristics and diet quality among pre-school children in dual-parent households: results from a population-based cohort in Taiwan
Authors: Wu Jennifer Chun-Li 
Published: December 2017

AbstractObjectiveTo examine the relationship between parental work characteristics and diet quality among pre-school children in dual-parent households.DesignCross-sectional study. Parental work characteristics were measured by the types of combined parental work schedules and work hours. The main outcome variables included meal eating habits as well as ‘health-conscious food’ and ‘unhealthy non-core food’ dietary patterns derived by using principal component analysis. Sociodemographic covariates were considered to reduce confounding and selection biases.SettingThe Taiwan Birth Cohort Study, Taiwan.SubjectsA population-based sample of 18 046 children.ResultsMultiple regression analyses indicated that compared with having both parents working standard schedules, having at least one parent who worked non-standard schedules was significantly associated with a lower likelihood of a child eating breakfast every day and a higher consumption of unhealthy non-core foods. If only one parent was employed and worked standard schedules, the children demonstrated greater odds of having home-prepared dinner most of the time. The mother’s working long hours was associated with lower odds of eating breakfast every day, more frequent consumption of unhealthy non-core foods and a lower frequency of healthy food consumption.ConclusionsThe findings raise concern that parents’ non-standard work schedules and mother’s long working hours have negative effects on diet quality of pre-school children. Policy implications include the need for a multifaceted approach to supporting working parents so as to create healthier food environments.
