Detection of Machine Failure by Using Information on Higher‐Order Correlations Between Sound and Vibration
Authors: Ikuta Akira , Orimoto Hisako , Ogawa Hitoshi 
Published: September 2013

SUMMARYIn this study, a method for stochastic detection of the failure of machines based on changes in information not only on linear correlations but also on higher‐order nonlinear correlations is proposed in a form suitable for on‐line signal processing in the time domain on a personal computer, especially in order to find in detail the mutual relationship between sound and vibration emitted from rotational machines. More specifically, a conditional probability hierarchically reflecting various types of correlation information is theoretically derived by introducing an expression for the multidimensional probability distribution in orthogonal expansion series form. The effectiveness of the proposed theory is experimentally confirmed by applying it to observed data emitted from a rotational machine driven by an electric motor. © 2013 Wiley Periodicals, Inc.

AbstractThe oxidation of phenol, cychohexanol and hydroquinone has been screened in the presence of copper(II) complexes with the Schiff‐base salen ligand, 1,5‐bis[(E)‐5‐chloro‐2‐hydroxybenzylideneamino]‐1H‐imidazole‐4‐carbonitrile, and encapsulated into NaY zeolite by using two different methods. The new heterogeneous catalysts were characterized by SEM, XRD, FTIR, EPR and Raman spectroscopy as well as by chemical analysis. The structures of the copper(II) complexes were proposed on the basis of theoretical studies (DFT). The catalytic activities of the encapsulated copper(II) complexes in NaY were compared with their homogeneous counterparts. The results show higher or similar substrate conversion when compared with the free complex in all the reactions tested. After their use in catalytic reaction, these catalysts were found to be reusable without loss of activity.

AbstractA set of ferrocenyl boronate esters based on carbohydrate scaffolds was designed and synthesized efficiently by the reaction of ferroceneboronic acid with protected sugar diols derived from D‐xylose, L‐sorbose, and D‐mannitol in good yield. These compounds identified as 1,2‐O‐isopropylidene‐α‐D‐xylofuranose‐3,5‐ferrocenyl boronate (3a), 1,2‐O‐cyclohexylidene‐α‐D‐xylofuranose‐3,5‐ferrocenyl boronate (3b), 1‐O‐benzyl‐2,3‐O‐isopropylidene‐α‐L‐sorbofuranose‐4,6‐ferrocenyl boronate (3c), 1,2:5,6‐di‐O‐isopropylidene‐D‐mannitol‐3,4‐ferrocenyl boronate (3d), and 1,2:5,6‐di‐O‐cyclohexylidene‐D‐mannitol‐3,4‐ferrocenyl boronate (3e), were isolated as air‐ and moisture‐stable orange/yellow crystalline solids. All of the six‐membered (3a, 3b, and 3c) and five‐membered (3d and 3e) cyclic boronate esters were fully characterized by IR, multinuclear NMR (1H, 13C and 11B), and UV/Vis spectroscopy, and also elemental analysis. The electrochemical behavior of the synthesized ferrocenyl boronate esters containing carbohydrates was investigated. Furthermore, the structures of 3a and 3c were unambiguously established by single‐crystal X‐ray diffraction analysis. The compounds have been screened for in vitro antibacterial activity against various Gram‐positive and Gram‐negative bacteria. They exhibited moderate to good inhibitory activity against the tested bacterial strains in comparison with standard drugs.

Published: September 2013

AbstractA novel palladium‐catalyzed coupling reaction of an aryl methyl ketone with two molecules of an aryl halide to yield symmetric diarylmethanes is described. In the facile one‐pot reaction, the aryl methyl ketone acts as a formal methylene donor. The experimental facts, including TLC monitoring, speculated intermediates as the raw materials, analysis of the cesium benzoate coproduct by ex situ IR spectroscopy, and the cross‐coupling reactions of two different aryl halides, indicate a mechanism involving a palladium‐catalyzed sequential two‐step coupling process, in which the presence of a trace amount of H2O is indispensable. The reaction is applicable to a broad spectrum of substrates and delivers the products in good to excellent yields. Access to unsymmetrical diarylmethanes with this method is also explored and various factors are discussed.

Published: September 2013

AbstractThe synthesis of 2,6‐dialkyl(aryl)purine nucleosides by application of a double addition of Grignard reagents to N1‐oxide purine nucleosides is described. The synthetic protocol exploits the reactivity of both the C6–N1–O– and C2–N1–O– moieties of the purine base. The overall process consists of initial Grignard reagent addition to the C6 of nebularine N1‐oxide followed by aromatization to give a C6‐substituted nucleoside. Regeneration of the N1‐oxide is then followed by a second Grignard addition at C2 causing the opening of the pyrimidine ring. Cyclization of the transiently opened pyrimidine is then driven by aromatization of the system to afford the final purine system.

Published: September 2013

AbstractA membrane electrode assembly (MEA) is one of the core components of proton exchange membrane fuel cells (PEMFCs) comprising a catalyst coated membrane, gas diffusion electrodes, frames, and seals. By employing a 2D finite element model the mechanical stresses in membrane caused during the cell assembly procedure are analyzed for different MEA frame materials, frame structures and contact behaviors. The stress distributions in the membrane are presented and quantified. A zone with strong nonuniform stresses in the membrane under the end edge of frame/membrane is observed. The stepped frames assembly (SFA) and the bonded contact behaviors have more uniform stress distributions than the aligned frames assembly (AFA) does. The frame materials are not the main factors affecting the stress concentration in membrane for the SFA, while for the AFA the mechanical properties of frame materials should be close to those of the membrane. The results are expected to be helpful for people to select the frame materials and to design frame structures, and can be applied to guide the assembly of PEMFCs.

Authors: Liu T. 
Published: September 2013

AbstractThe cobaltate perovskites Sr1–xDyxCoO3–δ (SDCO, x = 0.1, 0.2, 0.3) materials were synthesized and evaluated as cathode for La0.8Sr0.2Ga0.8Mg0.2O3–δ solid electrolyte supported intermediate‐temperature‐solid oxide fuel cells (IT‐SOFCs). The crystal structure of Sr0.9Dy0.1CoO3–δ was defined in the cubic Pm–3m space group (No. 221), Sr0.8Dy0.2CoO3–δ and Sr0.7Dy0.3CoO3–δ had a tetragonal I4/mmm structure. The electrical conductivities were all higher than 100 S cm–1 in the temperature of 170–800 °C. The polarization resistance (Rp) and its activation energy (Ea) increased with increasing x. SEM analysis confirmed the porous microstructure of the SDCO cathodes and good LSGM|LDC|SDCO adherence. Sr0.9Dy0.1CoO3–δ exhibited the best cathode characteristics with a maximum test‐cell power density of 841 mW cm–2, being a high potential candidate of cathode material for IT‐SOFCs.
Residual Stress Assessment for Thin 8YSZ Electrolytes Using Focused Ion Beam Milling and Digital Image Correlation
Authors: Malzbender J. , Van Gestel T. 
Published: September 2013

AbstractWith respect to solid oxide fuel cell power density it has been verified that 1–2 μm thick 8YSZ electrolytes have significant advantages, offering the potential to operate stacks at temperatures of 600 °C. However, reliability of the component depends on integrity and hence residual stress state. In this work, an advanced method is used to determine the electrolyte residual stress locally using stress relaxation tests by a combination of focused ion beam milling and digital image correlation.
The influence of water vapor absorption in the 290–350 nm region on solar radiance: Laboratory studies and model simulation
Authors: Du Juan , Huang Li , Min Qilong , Zhu Lei 
Published: September 2013

AbstractWater vapor is an important greenhouse gas in the Earth's atmosphere. Absorption of solar radiation by water vapor in the near‐UV region may partially account for up to 30% discrepancy between the modeled and the observed solar energy absorbed by the atmosphere. But the magnitude of water vapor absorption in the near‐UV region at wavelengths shorter than 384 nm is not known. We have determined absorption cross sections of water vapor at 5 nm intervals in the 290–350 nm region, by using cavity ring‐down spectroscopy. Water vapor cross‐section values range from 2.94 × 10−24 to 2.13 × 10−25 cm2/molecule in the wavelength region studied. The effect of the water vapor absorption in the 290–350 nm region on the modeled radiation flux at the ground level has been evaluated using radiative transfer model.
The Ties That Bind: Family Systems Correlates of Parental Decision‐Making in Custody/Access Disputes
Authors: Renouf Emilia 
Published: September 2013

Family systems theorists have developed certain concepts which they claim predict marriage outcome and the possible success of divorce mediation, should the marriage fail.In this paper I examine concepts of individual and family functioning. The concept of ‘emotional flexibility’ is presented as a criterion predisposing marriage partners to a more or less fused marriage. This in turn, is seen as predisposing the partners, in the event of separation, either to search for their own parental agreement with regard to their children's wellbeing, or to insist on a Judicial decision. In order to test the applicability of this concept, I explore the results of 64 conciliation conferences conducted by me in the Sydney Registry of the Family Court.I also consider a typology of divorcing couples worked out by divorce therapists, which uses type of spousal interaction as a criterion for predicting suitability for divorce mediation. I analyse the results of 30 Family Reports prepared by me, to test the usefulness of the typology for deciding on the most appropriate method of family dispute resolution for a given couple.I conclude by suggesting systematic exploration of core family system concepts and variables having a modulating effect, that can be used as predictors of client suitability for negotiation as well as to anticipate the type of custody/access arrangements that can be achieved.
Informational Writing in High School Science
Authors: Kohnen Angela M. 
Published: September 2013

AbstractAs states continue to implementCCSS, science teachers will be asked to incorporate more discipline‐specific reading and writing in their classes. Yet, according to national studies, few science teachers have previous experience to draw upon and most have little to no training in writing pedagogy. This article reports on one science teacher's successful implementation of a science journalism writing assignment in her high school chemistry class. Her success was attributed to two factors: (a) time to learn and understand a discipline‐specific genre that was suitable for classroom use, and (b) the existence of a publication outlet which allowed her to create a community of practice where students could enter as legitimate peripheral participants and ultimately become published authors. Each of these factors contributed to a classroom where writing was not simply five‐paragraph essays, where success was modeled, where peer editing was a privilege, and where publication was the expectation.

Published: September 2013

ABSTRACTToxicogenomics (TGx) has played a significant role in mechanistic research related with hepatotoxicity as well as liver toxicity prediction. Currently, several large‐scale preclinical TGx data sets were made freely accessible to the public, such as Open TG‐GATEs. With the availability of a sufficient amount of microarray data, it is important to integrate this information to provide new insights into the risk assessment of potential drug‐induced liver toxicity. Here we developed a web server for evaluating the potential liver toxicity based on genome‐wide transcriptomics data, namely LTMap. In LTMap, researchers could compare signatures of query compounds against a pregenerated signature database of 20 123 Affymetrix arrays associated with about 170 compounds retrieved from the largest public toxicogenomics data set Open TG‐GATEs. Results from this comparison may lead to the unexpected discovery of similar toxicological responses between chemicals. We validated our computational approach for similarity comparison using three example drugs. Our successful applications of LTMap in these case studies demonstrated its utility in revealing the connection of chemicals according to similar toxicological behaviors. Furthermore, a user‐friendly web interface is provided by LTMap to browse and search toxicogenomics data (http://tcm.zju.edu.cn/ltmap). Copyright © 2013 John Wiley & Sons, Ltd.
Nanoscale topographic changes on sterilized glass surfaces affect cell adhesion and spreading
Authors: Wittenburg Gretel , Lauer Günter , Oswald Steffen , Labudde Dirk , Franz Clemens M. 
Published: September 2013

AbstractProducing sterile glass surfaces is of great importance for a wide range of laboratory and medical applications, including in vitro cell culture and tissue engineering. However, sterilization may change the surface properties of glass and thereby affect its use for medical applications, for instance as a substrate for culturing cells. To investigate potential effects of sterilization on glass surface topography, borosilicate glass coverslips were left untreated or subjected to several common sterilization procedures, including low‐temperature plasma gas, gamma irradiation and steam. Imaging by atomic force microscopy demonstrated that the surface of untreated borosilicate coverslips features a complex landscape of microislands ranging from 1000 to 3000 nm in diameter and 1 to 3 nm in height. Steam treatment completely removes these microislands, producing a nanosmooth glass surface. In contrast, plasma treatment partially degrades the microisland structure, while gamma irradiation has no effect on microisland topography. To test for possible effects of the nanotopographic structures on cell adhesion, human gingival fibroblasts were seeded on untreated or sterilized glass surfaces. Analyzing fibroblast adhesion 3, 6, and 24 h after cell seeding revealed significant differences in cell attachment and spreading depending on the sterilization method applied. Furthermore, single‐cell force spectroscopy revealed a connection between the nanotopographic landscape of glass and the formation of cellular adhesion forces, indicating that fibroblasts generally adhere weakly to nanosmooth but strongly to nanorough glass surfaces. Nanotopographic changes induced by different sterilization methods may therefore need to be considered when preparing sterile glass surfaces for cell culture or biomedical applications. © 2013 Wiley Periodicals, Inc.

AbstractCancer‐initiating cells [cancer stem cells (CSCs)] in colon cancer cells can be selectively suppressed when they are cultured on Pluronic (nanosegment)‐grafted dishes, whereas CSCs are maintained on conventional tissue culture dishes and extracellular matrix‐coated dishes. CSCs persist in tumors as a distinct population and cause relapse and metastasis by giving rise to new tumorigenic clones. The purification or depletion (suppression) of CSCs should be useful for analyzing CSC characteristics and for clinical application. CSCs can be selectively suppressed from colon cancer cells containing adipose‐derived stem cells (ADSCs) on Pluronic‐grafted dishes, while ADSCs remain on the dishes. ADSCs on Pluronic‐grafted dishes after the suppression of the CSCs can differentiate into osteoblasts, chondrocytes, adipocytes, cardiomyocytes, and neuronal cells. The CSCs and ADSCs exhibited different characteristics. The selection of ADSCs was possible on Pluronic‐grafted dishes that suppressed the CSCs from the fat tissues of cancer patients (i.e., cell‐sorting dishes), which was explained by specific biomedical characteristics of Pluronic. © 2013 Wiley Periodicals, Inc.

Paleoseismology of the southern Panamint Valley fault: Implications for regional earthquake occurrence and seismic hazard in southern California

Published: September 2013

AbstractPaleoseismologic data from the southern Panamint Valley fault (PVF) reveal evidence of at least four surface ruptures during late Holocene time (0.33–0.48 ka, 0.9–3.0 ka, 3.3–3.6 ka, and >4.1 ka). These paleo‐earthquake ages indicate that the southern PVF has ruptured at least once and possibly twice during the ongoing (≤1.5 ka) seismic cluster in the Mojave section of the eastern California shear zone (ECSZ). The most recent event (MRE) on the PVF is also similar in age to the 1872 Owens Valley earthquake and the geomorphically youthful MRE on the Death Valley fault. The timing of the three oldest events at our site shows that the PVF ruptured at least once and possibly thrice during the well‐defined 2–5 ka seismic lull in the Mojave section of the ECSZ. Interestingly, the 3.3–3.6 ka age of Event 3 overlaps with the 3.3–3.8 ka age of the penultimate (i.e., pre‐1872) rupture on the central Owens Valley fault. These new PVF data support the notion that earthquake occurrence in the ECSZ may be spatially and temporally complex, with earthquake clusters occurring in different regions at different times. Coulomb failure function modeling of the Panamint Valley and Garlock faults reveals significant stress interactions between these two faults that may influence future earthquake occurrence. Specifically, our models suggest a possible rupture sequence whereby an event on the southern Panamint Valley fault can lead to the potential triggering of an event on the Garlock fault, which in turn could trigger the Mojave section of the San Andreas Fault.
Timely measles surveillance in the Republic of Korea, 2002–2009: Impact of sentinel laboratory surveillance
Authors: Choe Young June , Eom Hye Suk , Bae Geun‐Ryang , Cho Sung‐Il 
Published: September 2013

AbstractIn order to sustain the elimination of measles, timely reporting is important. The surveillance data in Korea from 2002–2009 was analyzed to determine the effect of sentinel laboratory surveillance, which was introduced in 2006, on the timeliness of measles reporting. The data were stratified by two surveillance periods, (A) before and (B) after 2006, and by cases confirmed clinically and cases confirmed by laboratory measures. During Period A, 113 suspected cases were reported, and 241 during Period B. There was no difference in the proportion of timely reporting among cases confirmed clinically between the two periods, whereas the proportion of cases confirmed by laboratory measures has increased. The mean notification interval in cases confirmed by laboratory measures was shortened from 39 to 16 days. In Korea, sentinel laboratory surveillance has enhanced earlier detection of suspected cases that had not been reported, improving the timeliness of measles surveillance. Adopting this new method may improve the timely collection of cases in other countries. J. Med. Virol. 86:322–328, 2014. © 2013 The Authors.
