Authors: Sieslack Anne K. , Dziallas Peter , Nolte Ingo , Wefstaedt Patrick 
Published: June 2013

Abstract
Objective—To evaluate the accuracy and reproducibility of left ventricular (LV) volumetric and function variables determined via contrast-enhanced cardiac CT and cardiac MRI in healthy dogs.
Animals—10 healthy Beagles.
Procedures—Cardiac MRI and cardiac CT were performed in anesthetized Beagles; both examinations were conducted within a 2-hour period. Cardiac MRI was performed with a 3.0-T magnet, and contrast-enhanced cardiac CT was performed with a 64-row detector CT machine. Data sets were acquired during apnea with simultaneous ECG gating. Short-axis images were created to determine functional variables via the Simpson method.
Results—Cardiac CT values for mean end-diastolic and end-systolic LV volumes had excellent correlation (r = 0.95) with cardiac MRI measurements, whereas LV stroke volume (r = 0.67) and LV ejection fraction (r = 0.75) had good correlations. The only variable that differed significantly between imaging modalities was end-diastolic LV volume. For each pair of values, Bland-Altman analysis revealed good limits of agreement.
Conclusions and Clinical Relevance—The 3-D modalities cardiac CT and cardiac MRI were excellent techniques for use in assessing LV functional variables. Similar results were obtained for LV volume and function variables via both techniques. The major disadvantage of these modalities was the need to anesthetize the dogs for the examinations.
Incertitude scientifique et incertitude fabriquée
Authors: Henry Claude 
Published: June 2013

John Maynard Keynes, dans son Treatise on Probability (1921), distingue clairement l’incertitude et le risque, le risque étant de l’incertitude complètement structurée par des probabilités objectives. En baptisant « principe d’incertitude » le fameux principe qu’il a mis au cœur de la mécanique quantique, Heisenberg a ignoré la distinction keynésienne. La mécanique quantique en effet, tout en écartant la causalité déterministe, caractérise tous les phénomènes physiques de son ressort en termes de distributions complètes de probabilités objectives. En revanche, des sciences comme l’écologie, la climatologie, l’océanographie, et, à bien des égards, la science médicale, sont au moins partiellement des sciences incertaines au sens de Keynes. Cela ne les rend pas inaptes à éclairer des décisions collectives dont les conséquences peuvent être lourdes, dans la mesure où des méthodes rigoureuses ont été développées à cet effet – et expérimentées – dans un passé récent. Mais cela les rend vulnérables à des manipulations de l’incertitude qu’elles comportent, manipulations qui visent à les discréditer dans leur capacité à éclairer les décisions à prendre.
Finance des risques catastrophiques
Authors: Michel-Kerjan Erwann 
Published: June 2013

Les catastrophes en série survenues depuis 2001 aux États-Unis ont causé des pertes historiques et obligent à repenser les fondamentaux de la couverture financière du risque et le rôle des secteurs public et privé en matière d’assurabilité des désastres. Dans un marché fortement régulé, aux intérêts économiques et politiques locaux importants, les grands assureurs se désengagent des États américains les plus exposés, faute de pouvoir charger le prix qu’ils estiment nécessaire, faisant place à un mixte d’assurance publique fortement subventionnée et de financement ex post à travers des programmes fédéraux d’aides aux victimes non assurées de plus en plus sollicités. Une situation paradoxale dans un pays souvent considéré en Europe comme l’antre du « tout marché ». Si l’intervention gouvernementale dans les marchés d’assurance peut être légitime en cas de limite d’assurabilité afin de bénéficier d’un coût du capital plus faible pour couvrir des risques véritablement extrêmes, cette situation est intenable à long terme, car elle soutient un cercle vicieux de prise de risque qui accroît la vulnérabilité. Des propositions alternatives sont actuellement évaluées par le Congrès américain.
La ruine de l'en-attendant : un cas d'éphémère continu
Authors: Baillargeon Taïka 
Published: June 2013

Le présent article concerne la ruine post-catastrophe qui subsiste dans le temps. On ne parle pas ici d’une ruine du temps, mais d’une ruine inattendue, voire même non désirée, qui habite l’espace-temps en attente d’une transformation. Cette ruine ne tient plus d’une nostalgie du passé, elle n’est plus cette trace que l’on préserve volontairement, il s’agit d’un entre-deux qui se veut éphémère. Il arrive pourtant parfois que cette ruine subsiste et que l’éphémère devienne continu. Comment penser cet éphémère continu ? Pour mieux comprendre cette problématique et approfondir un questionnement exploratoire sur cette notion nouvelle, nous proposons de nous pencher sur l’exemple du Generalstab à Belgrade (Serbie).
Pratiques sportives et usages liquides
Authors: Urteaga Eguzki , Aldaz Juan 
Published: June 2013

Le présent article a pour objet de montrer de quelle façon les pratiques sportives apparaissent comme des illustrations paradigmatiques des usages liquides. Nous partons de la prémisse selon laquelle les individus sont des êtres constructeurs et en construction, de sorte que les personnes soient en perpétuel mouvement et en constante activité physique. Dès lors, l’on pourrait affirmer que, dans l’idéal de l’ Homo Faber , il existe une caractéristique essentielle relative à notre caractère d’ Homo Impiger , c’est-à-dire d’être actif. La particularité de la pratique sportive ainsi que de l’ensemble des pratiques sociales des individus de la modernité liquide est une spécificité historique caractérisée par trois processus spécialement significatifs et reliés entre eux : 1) le processus de technicisation, 2) le processus d’acculturation, 3) le processus de reconstruction et de réinstitutionnalisation.
Die vrou in die kerkgeskiedenis
Authors: Boeseken A. 
Published: June 2013

Die onderwerp, "Die vrou in die kerkgeskiedenis” is so veelsydig as die lewe self en die eerste vraag wat opduik is: "Waar begin die kerkgeskiedenis?” Daaroor het in boeke wat in die dertigerjare van hierdie eeu geskryf is, geen eenstemmigheid geheers nie. In ’n beknopte geskiedenis van wat Spoelstra vir katkisante geskryf het, verduidelik hy dat die kerkgeskiedenis by Adam en Eva begin, terwyl in hul "Kerkgeskiedenis vir ons Volk” A. M. Kriel en G. B. A. Gerdener skryf dat die kerkgeskiedenis op die Pinksterdag begin. (Hiermee stem S. du Toit asook Spoelstra, Pont en Keet saam). G. S. Wegener sê in "Die Lewende Kerk” dat dit op Golgotha "in vertwyfeling, wanhoop en vrees” begin. Maar nou wil ek as "leek” en miskien as "ketter” van al hierdie geleerde uitsprake verskil. Vir my begin die kerkgeskiedenis met die opstanding van Christus uit die graf, toe Hy volgens Job. 20:7 aan Maria gesê het: "Gaan na my broeders en sê vir hulle: "Ek vaar op na my Vader en julle Vader en na my God en julle God”.
Tot lof van die kerkorde ... in sy dienskneggewaad

Published: June 2013

Dit is eg Gereformeerd om te sê dat die kerkorde nie ’n wetboek is nie. En ons is heel dikwels eg Gereformeerd! Maar hoe dan met die kerkorde gemaak? Jou oë vir hom sluit, hom tong in die kies venuftig probeer systap; of tog dan maar ’n wet van hom gaan staan en maak? Moet ons hom maar aanvaar as die erflike las waarmee die kerk sit en wat nou eenmaal saamgesleep móét word? Moet ons hom maar in ons midde duld as die arsenaal waaruit die grootkanonne hulle kartetse haal om met baie donder en min erbarming hulle (vermoedelike) teëstanders op kerklike vergaderings mee plat te skiet?

Twee vroeë reaksies van Gereformeerde kant op Karl Barth
Authors: Engelbrecht B. J. 
Published: June 2013

In 1919 het die eerste uitgawe van die epogmakende “Romerbrief” van Karl Barth verskyn. Van die tweede druk in 1922 sê hy dat “kein Stein mehr auf dem andem” gelaat is nie. So opspraakwekkend was hierdie boek dat in 1929 die 5de druk van die tweede, radikaal-hersiene uitgawe verskyn het. Intussen het nog ander werke van Barth en selfs oor Barth verskyn. 0ns noem o.a. sy Der Christ in der Gesellschaft (1920); Das Wort Gottes und die Theologie (1924); Vom Christlichen Leben (1926); Auferstehung der Toten (2. Aufl. 1927), sy preke saam met Eduard Thurneysen Komm Schopfer Geist, (Dritt Aufl., 7-9 Tausend(!) 1926). Maar 1927 was veral belangrik vanweë die verskyning van Barth se eerste Dogmatiekboek: “Die Christliche Dogmatik im Entwurf. 1 Die Lehre vom Worte Gottes. Prolegomena zur Christlichen Dogmatik” . Voor dié datum het dwarsoor die wêreld, maar ook in Nederland wye reaksie op sy teologie ontstaan. In 1926 skryf Max Strauch sy “Theologie Karl Barth’s”, terwyl Haitjema in Nederland ook in 1926 sy Barth boek die lig laat sien (Prof. dr. Th. L. Haitjema, Karl Barth, Wageningen 1926.) Ander Nederlanders wat gereageer het, was drr. A. H. de Hartog, V. Hepp, Ph. Kohnstamm en di. D. Tromp en 0. Noordmans.
’n Skriftuurlike evaluering van artikels 72-76 van die kerkorde van die GKSA
Authors: Kruger M. A. 
Published: June 2013

The articles on church discipline of the Reformed Churches in South Africa (GKSA) were founded almost exclusively on Calvin’s interpretation of Matthew 18:15 ff. Calvin, however, did not have manuscripts at his disposal which could enable him to do justice to the harmony of scriptural evidence for church discipline. He used texts in Matthew 18:15 as well as in Luke 17:3 which include the words "against you". With more manuscripts available today this interpertation of Matthew 18:15 should perhaps be reconsidered. Furthermore, development in the structural analysis of Scripture makes it necessary to re-examine the foundation which Calvin laid and the tradition which has been built on it.
Infinitesimal Rigidity of Convex Polyhedra through the Second Derivative of the Hilbert–Einstein Functional
Authors: Izmestiev Ivan 
Published: June 2013

Abstract. The paper presents a new proof of the infinitesimal rigidity of convex polyhedra. The proof is based on studying derivatives of the discrete Hilbert–Einstein functional on the space of “warped polyhedra” with a fixed metric on the boundary.The situation is in a sense dual to using derivatives of the volume in order to prove the Gauss infinitesimal rigidity of convex polyhedra. This latter kind of rigidity is related to the Minkowski theorem on the existence and uniqueness of a polyhedron with prescribed face normals and face areas.In the spherical space and in the hyperbolic-de Sitter space, there is a perfect duality between the Hilbert–Einstein functional and the volume, as well as between both kinds of rigidity.We review some of the related work and discuss directions for future research.

ObjectivesIn recent years, the use of computer‐based techniques has been advocated to improve intima‐media thickness (IMT) quantification and its reproducibility. The purpose of this study was to test the diagnostic performance of a new IMT automated algorithm, CARES 3.0, which is a patented class of IMT measurement systems called AtheroEdge (AtheroPoint, LLC, Roseville, CA).MethodsFrom 2 different institutions, we analyzed the carotid arteries of 250 patients. The automated CARES 3.0 algorithm was tested versus 2 other automated algorithms, 1 semiautomated algorithm, and a reader reference to assess the IMT measurements. Bland‐Altman analysis, regression analysis, and the Student t test were performed.ResultsCARES 3.0 showed an IMT measurement bias ± SD of −0.022 ± 0.288 mm compared with the expert reader. The average IMT by CARES 3.0 was 0.852 ± 0.248 mm, and that of the reader was 0.872 ± 0.325 mm. In the Bland‐Altman plots, the CARES 3.0 IMT measurements showed accurate values, with about 80% of the images having an IMT measurement bias ranging between −50% and +50%. These values were better than those of the previous CARES releases and the semiautomated algorithm. Regression analysis showed that, among all techniques, the best t value was between CARES 3.0 and the reader.ConclusionsWe have developed an improved fully automated technique for carotid IMT measurement on longitudinal ultrasound images. This new version, called CARES 3.0, consists of a new heuristic for lumen‐intima and media‐adventitia detection, which showed high accuracy and reproducibility for IMT measurement.

Published: June 2013

ObjectivesTo create reference charts for fetal sonographic biometric measurements in a population of pregnant women living in the third largest city in Colombia and compare them with charts included in ultrasound machines.MethodsThe data were obtained from women with a single pregnancy and confirmed gestational (menstrual) age between 12 and 40 weeks. All women were recruited specifically for the study, and every fetus was measured only once for biparietal diameter, head circumference, abdominal circumference, and femur length. Raw data for each fetal measurement were modeled by fitting regression models separately to estimate the mean and standard deviation as a function of gestational age. Percentile curves were constructed for each measurement by gestational age using these two regression models. We compared our mean z scores with those expected by reference equations.ResultsMeasurements were obtained for 792 fetuses. A cubic polynomial model was the best‐fitted regression model to describe the relationships between each fetal measurement and gestational age. The standard deviation for each measurement was estimated by simple linear regression as a function of gestational age. Comparison of our mean z scores with those by reference equations showed significant differences in some fetal measurements (P < .01).ConclusionsWe present a set of reference percentile charts, tables, and formulas for fetal biometric measurements from a Colombian population. We believe that our fetal charts could be used nationwide in Colombia; nevertheless, a national sample will contribute to their validation and promotion of the development of Colombian fetal size charts.
Read anything mean lately? Associations between reading aggression in books and aggressive behavior in adolescents

Published: June 2013

ABSTRACTAlthough there have been hundreds of studies on media violence, few have focused on literature, with none examining novels. Accordingly, the aim of the current study was to examine whether reading physical and relational aggression in books was associated with aggressive behavior in adolescents. Participants consisted of 223 adolescents who completed a variety of measures detailing their media use and aggressive behavior. A non‐recursive structural equation model revealed that reading aggression in books was positively associated with aggressive behavior, even after controlling for exposure to aggression in other forms of media. Associations were only found for congruent forms of aggression. Implications regarding books as a form of media are discussed. Aggr. Behav. 39:493–502, 2013. © 2013 Wiley Periodicals, Inc.
Seamless Integration of an Elastomer with Electrode Matrix and its In‐Situ Conversion into a Solid State Electrolyte for Robust Li‐Ion Batteries

Published: June 2013

AbstractA unique way of robustly integrating an elastomer film onto a graphitic anode and then post process it into a solid‐state electrolyte for lithium‐ion battery applications is reported. The mutual solvability of the elastomer and the binder of the graphitic anode (carboxymethyl cellulose, (CMC)) in dimethylformamide facilitates the fusion of the two heterogeneous layers. Dimensional dynamics evolved during the integrated elastomer conversion into a solid electrolyte by liquid electrolyte uptake reveal a notable preferential uniaxial elongation along the normal plane. In contrast, the non‐integrated counterpart elongates along the transversal axis. These elastomer exhibits high ionic conductance (≈10–2 S cm−1). Half‐cells constructed with our electrolyte integrated electrode exhibit magnificent reduction and oxidation (REDOX) behavior. The efficient charge transfer across the snugly confined semi‐solid electrolyte/electrode interface layer leads to a high rate capability of 0.31 mAh cm−2 (41 mAh g−1) at 2 C which is double that of a graphitic conventional half‐cell. Unlike regular graphitic electrodes which degrade over time, this electrode remains robust, thanks to its propensity to retain its inherent elasticity. This work demonstrates a facile and scalable paradigm, in fabrication of flexible electrolytes that can easily be integrated to 3D devices and opens opportunities for developing, structurally conformable batteries of varied geometries.

Published: June 2013

AbstractThe need for transparent conductors (TCs) that are capable of withstanding high mechanical deformation in comparison to the brittle indium tin oxide (ITO) films is paramount for roll‐to‐roll production of flexible and stretchable displays, signage systems, lighting devices and solar panels with stringent weatherability requirements. This paper reports a highly stretchable TC comprising of a web of core‐shell nanofibers, which mimics the fibrous structure of natural systems such as veins of a leaf or nerve systems. The TC web demonstrates high transparency, low sheet resistance, and unprecedented stretchability and stability over repeated stretching. The nanofiber TC web can be transferred to different substrates, which is manifested by the transfer onto an organic solar cell, demonstrating a photovoltaic performance comparable to that of a device with an ITO electrode. This work presents a technological platform, scalable for the manufacturing of large area transparent conductors for flexible and stretchable displays, electronics and solar cells on unconventional substrates such as rubber, fabric and paper.

AbstractOsteogenesis imperfecta (OI) type V is a specific OI phenotype with interosseous membrane calcification of the forearm and hyperplastic callus formation as typical features. The causative gene mutation for OI type V has been recently discovered. The purpose of this report is to review the clinical and radiographic characteristics of mutation confirmed OI type V in detail. Sixteen (nine familial and seven sporadic) patients were enrolled in the study. Blue sclera and dentinogenesis imperfecta were not evident in any patient. However, hypodontia in the permanent teeth, ectopic eruption, and short roots in molars were additionally observed in 11 patients. Of the radiographic abnormalities, cortical thickening and bony excrescence of interosseous margin of the ulna was the most common finding, followed by overgrowth of the olecranon and/or coronoid process of the ulna. Slender ribs and sloping of the posterior ribs with or without fractures were also a consistent finding. Hyperplastic callus was detected in 75% of patients and was commonly encountered at the femur. Heterotopic ossification in the muscles and tendon insertion sites were noted in four patients, which resulted in bony ankylosis or contracture of joints. The current study confirms common clinical and radiographic findings of OI type V and reports additional phenotypic information. These observations provide clues to recognize OI type V more promptly and guide to direct targeted molecular study. © 2013 Wiley Periodicals, Inc.

Published: June 2013

ABSTRACTConsidering the outstanding biocompatibility of Bombyx mori silk fibroin, this study is designed to fabricate biomimetic nanofibrous structure made of silk fibroin, which can enhance cell activities for tissue formation. The electrospinning of blend of silk fibroin with low molecular weight poly(ethylene‐oxide) (PEO) is explored with ease of preparation for high productivities. The average diameter of electrospun silk fibroin (eSF) is decreased from 414 ± 73 to 290 ± 46 nm after PEO extraction. To induce the desired cellular activity, the surface of the eSF fibers is modified with fibronectin by using the carbodiimide chemistry method. The potential use of the obtained wound healing material is assessed by indirect cytotoxicity evaluation on normal human dermal fibroblast (NHDF) in terms of their attachment and cell proliferation. The surface‐modified eSF nanofiber mats show good support for cellular adhesion and spreading as a result of fibronectin grafting on the fiber surface, especially for cell migration inside the fibrous structure. These results demonstrate a new fabrication technique of surface‐modified silk fibroin electrospun nanofibers for biomedical application; with the ability to accelerate wound healing. © 2013 Wiley Periodicals, Inc.
