Authors: Bauer Michael , Sigle Martin , Dostert Klaus 
Published: October 2010

Zusammenfassung
Informations- und Kommunikationstechnologien sind eine grundlegende Voraussetzung für die Realisierung sogenannter Smart Grids. Insbesondere für das Smart Metering, also die Vernetzung intelligenter Energiemengenzähler, besteht aktuell ein großer Bedarf an Kommunikationslösungen, wobei der Powerline-Kommunikation (Power Line Communication, PLC) aus ökonomischen Erwägungen besonders große Bedeutung zukommt. Einer relativ großen Auswahl an auf PLC basierenden Kommunikationssystemen stehen jedoch wenig verlässliche Informationen über deren Leistungsfähigkeit gegenüber. Es gilt also zunächst, die Fragen der Anwender nach der tatsächlichen Leistungsfähigkeit verschiedener Kommunikationssysteme zu beantworten. In diesem Beitrag werden zwei Ansätze beschrieben, die — mit Blick auf die physikalischen Eigenschaften des Energieverteilnetzes als Übertragungskanal — umfassende Antworten auf diese Fragen erlauben. Zudem werden Ergebnisse präsentiert, die eine realistische Einschätzung der Potenziale von auf PLC basierenden Kommunikationstechnologien erlauben.

Published: October 2010

Zusammenfassung
Data-Mining-Verfahren bauen auf einem umfangreichen Methodenapparat auf und werden seit langem erfolgreich auf verschiedenartige technische, naturwissenschaftliche und betriebswirtschaftliche Problemstellungen angewendet. Während sich Data-Mining-Verfahren ursprünglich auf tabellarische Datensätze mit einer überschaubaren Anzahl von Einzelmerkmalen bezogen, gewinnt die Verarbeitung von hochdimensionalen Daten aus Sensornetzen, fein abgetasteten Zeitreihen, Bildern und Videos zunehmend an Bedeutung. Der Beitrag stellt die zugrunde liegenden Methoden vor und gibt eine Übersicht über wichtige Anwendungsfelder.

Published: October 2010

OBJECTIVE:
To determine the stability of the scores obtained on tests of motor development from birth until school age in healthy, term singletons and to determine if early motor scores are associated with more complex cognitive functions at school age, such as attention and memory.

PATIENTS AND METHODS:
This longitudinal, prospective cohort study included 77 infants. The motor development of these infants was assessed during the neonatal period with Prechtl's neurologic examination; in early infancy with Touwen's neurologic examination and general movement assessment; at toddler age with Hempel's neurologic examination and the Psychomotor Developmental Index from the Bayley Scales of Infant Development; and at school age with the Movement Assessment Battery for Children. Cognition was determined at toddler age with the Mental Developmental Index from the Bayley Scales of Infant Development; and at school age with an intelligence test and attention and memory tests.

RESULTS:
The mean absolute difference in standardized motor scores for all time points was 1.01 SD (95% confidence interval: 0.91–1.11). Only the explained proportions of variance of maternal socioeconomic status and verbal intelligence were significant for sustained attention and verbal memory (r2 = 0.104, P = .030 and r2 = 0.074, P = .027), respectively. The children's scores on early motor tests added little value for their motor and cognitive development at school age.

CONCLUSIONS:
In healthy children the stability of motor development from birth until school age is low. Maternal socioeconomic status and verbal intelligence rather than the infants' scores on early motor tests signified added value for complex cognitive functions at school age.
Reverse Mathematics: The Playground of Logic
Authors: Shore Richard A. 
Published: October 2010

AbstractThis paper is essentially the author's Gödel Lecture at the ASL Logic Colloquium '09 in Sofia extended and supplemented by material from some other papers. After a brief description of traditional reverse mathematics, a computational approach to is presented. There are then discussions of some interactions between reverse mathematics and the major branches of mathematical logic in terms of the techniques they supply as well as theorems for analysis. The emphasis here is on ones that lie outside the usual main systems of reverse mathematics. While retaining the usual base theory and working still within second order arithmetic, theorems are described that range from those far below the usual systems to ones far above.
Serum Uric Acid Levels Predict New-Onset Type 2 Diabetes in Hospitalized Patients With Primary Hypertension: The MAGIC Study
Authors: Viazzi Francesca , Leoncini Giovanna , Vercelli Marina , Deferrari Giacomo , Pontremoli Roberto 
Published: October 2010

OBJECTIVE
Recent studies suggest that uric acid may predict the development of diabetes in the general population. Whether this association holds true in primary hypertension and is independent of renal function and metabolic syndrome is not clear at present.

RESEARCH DESIGN AND METHODS
In a prospective, observational study, 758 untreated hypertensive patients were evaluated at baseline and followed-up for 11 years.

RESULTS
A total of 8,332 person-years of follow-up revealed that slightly elevated uric acid levels (i.e., ≥318 μmol/l for women and ≥420 μmol/l for men) at baseline were associated with a significantly higher risk of developing diabetes (hazard ratio 3.65 [95% CI 1.99–6.69], P &lt; 0.0001), even after adjustment for several confounding factors such as metabolic syndrome (2.78 [1.35–5.70], P = 0.0054).

CONCLUSIONS
Uric acid is an independent predictor of diabetes in primary hypertension.

AbstractThe granule-dependent exocytosis pathway is an important mechanism to induce apoptosis by CD8+ T cells and NK cells and involves lytic molecules such as perforin. In the current study, we investigated the perforin 1 gene (PRF1) as a candidate for multiple sclerosis (MS) susceptibility in the Spanish population. We genotyped three PRF1 single nucleotide polymorphisms (rs885822, rs10999426, and rs3758562) in 420 patients with MS and 512 controls. Associations of PRF1 polymorphisms with the disease were restricted to male patients with MS, and the finding was consistently observed at the allele, genotype, and haplotype levels. Gender-associated differences were validated in an additional replication cohort comprised of 292 MS cases and 300 controls. In addition, we identified minor risk haplotypes strongly associated with male patients having primary progressive MS (PPMS). Further characterization of male patients with PPMS carrying the risk haplotypes by means of gene expression microarrays revealed overrepresentation of the cell killing gene ontology category among downregulated genes in these patients compared with male patients with PPMS carrying protective haplotypes. Moreover, PRF1 mRNA expression levels were significantly lower in patients with risk haplotypes, and changes in perforin protein expression by CD8+ T cells mirrored those observed in gene expression. These findings suggest a gender dimorphism in the PRF1 association with MS and point to the presence of a generalized defect in the expression of genes that code for proteins involved in cell killing in a subgroup of male patients with PPMS.
Totally Implantable Hearing Devices

Published: October 2010

AbstractHearing aids are the principal means of auditory rehabilitation for patients with moderate to severe sensori-neural hearing loss. Although technical improvements and modifications have improved the fidelity of conventional aids, hearing aids still have many limitations including the inherent self consciousness and social stigma attached to visible hearing aids. The recently introduced totally implantable hearing aids offer patients with hearing loss several potential advantages over conventional hearing aids. This article reviews the indications, surgical procedure, advantages and the current status of totally implantable hearing devices.
Auditory Brainstem Implants
Authors: Kameswaran Mohan , Raghunandhan S 
Published: October 2010

AbstractAuditory brainstem implants (ABIs) are currently indicated for patients with neurofibromatosis type 2 (NF-2) tumors involving both vestibulocochlear nerves. The ABI helps bypass the damaged cochlear nerves and stimulates the cochlear nucleus in the brainstem directly thereby restoring auditory sensation. The implant is usually placed in the lateral recess of the fourth ventricle after tumor resection. The indications for ABI have recently expanded onto even nontumoral cases, such as congenital bilateral cochlear nerve aplasia. In such cases, the ABI helps bypass the nonfunctioning hypoplastic or absent cochlear nerves and stimulates the cochlear nucleus directly thereby restoring auditory sensation. This article reviews the nuances of this sophisticated implant, shares our experience with auditory brainstem implantation and its current status in world literature.
A new approach to the study of Romanization in Britain: A regional perspective of cultural change in late Iron Age and Roman Dorset using the Siler and Gompertz–Makeham models of mortality
Authors: Redfern Rebecca C. , DeWitte Sharon N. 
Published: October 2010

AbstractThis is the first study of health in the Roman Empire to use the Siler and Gompertz–Makeham models of mortality to investigate the health consequences of the 43 AD conquest of Britain. The study examined late Iron Age and Romano‐British populations (N= 518) from Dorset, England, which is the only region of Britain to display continuity in inhumation burial practice and cemetery use throughout the two periods. Skeletal evidence for frailty was assessed using cribra orbitalia, porotic hyperostosis, periosteal lesions, enamel hypoplasia, dental caries, tuberculosis, and rickets. These health variables were chosen for analysis because they are reliable indicators of general health for diachronic comparison (Steckel and Rose: The backbone of history: health and nutrition in the western hemisphere (2002)) and are associated with the introduction of urbanism in Britain during the Roman period (Redfern: J Rom Archaeol Supp Series 64 (2007) 171–194; Redfern: Britannia 39 (2008a) 161–191; Roberts and Cox: Health and disease in Britain: from prehistory to the present day (2003)). The results show that levels of frailty and mortality were lower in the late Iron Age period, and no sex differences in mortality was present. However, post‐conquest, mortality risk increased for children and the elderly, and particularly for men. The latter finding challenges received wisdom concerning the benefits of incorporation into the Empire and the higher status of the male body in the Roman world. Therefore, we conclude that the consequences of urbanism, changes in diet, and increased population heterogeneity negatively impacted health, to the extent that the enhanced cultural buffering of men did not outweigh underlying sex differences in biology that advantage women.

Cation radicals of organogermatranes
Authors: Soualmi Saida , Ignatovich Luba , Jouikov Viatcheslav 
Published: October 2010

AbstractCation radicals (CRs) of 1‐substituted germatranes were generated by one‐electron electrochemical oxidation and studied by real‐time EPR spectroscopy for the first time. In contrast to CRs of trialkylamines, the CRs of germatranes are much more stable and can be observed in acetonitrile solution at 253 K. As follows from g‐factors and hfc constants, spin density in the CRs of aryl germatranes is localized mainly on the axially directed pz orbital of N atom, pointed inside the atrane cage. EPR spectroscopy and Fermi contact coupling from DFT B3LYP/LANL2DZ calculations reveal an interesting feature: no contribution from the Ge atom was found in the spin delocalization in these species. Contrary to the neutral germatranes and to what was expected from the qualitative estimations, the nitrogen atom in the CR does not adopt an exo‐configuration and is practically planar. Experimental hfc constants and DFT B3LYP/LANL2DZ calculations support the observed feature: the geometry around the N atom in CR is close to planar whereas the Ge atom undergoes remarkable reorganization, approaching a trigonal bipyramid in benzyl germatranes and tetrahedral configuration in aryl germatranes. 1‐Substitution of germatranes with the groups with low own ionization potential (R2NC6H4‐, where R = Me, Et) inverts the roles of the fragments—upon electrooxidation, these compounds behave as corresponding germatranyl‐substituted organic derivatives.

Evaluating prioritization of ASEAN highway network development using a fuzzy multiple attribute decision making method
Authors: Lee Dongmin , Han Sang‐Jin , Kim Do‐Gyeong 
Published: October 2010

AbstractThe association of South East Asian Nations (ASEAN) has recently decided to develop a new highway network to connect countries in the association by roads to enhance cultural integration and economic growth of Asian countries. A total of 5400 km of roads are required to be newly constructed or upgraded to develop the ASEAN highway network. In this study, prioritization of investment for 32 road sections in the ASEAN highway network construction was evaluated using a two‐step hierarchical fuzzy multiple attribute decision‐making (MADM) process. The first step was to prioritize each corridor, and the second step was to prioritize individual roads within each corridor. In this prioritization, the importance of road sections was evaluated based on economic and political aspects. The economic aspect was assessed using traffic volume and construction cost while the political aspect was assessed using data related to balancing regional development, a country's willingness to invest, road network connectivity, and priority of each corridor. The road sections from Mawlamyine to Thanbyuzayat were identified as the highest priority road sections for construction. Also, it was found that the application of the Fuzzy MADM process for evaluating the prioritization of road construction is a useful and beneficial method in prioritizing highway development across various regions such as Southeast Asian countries.

Baugrubenverformungen in weichen Böden bei spannungspfadabhängigem Materialverhalten
Authors: Becker Patrick , Kempfert Hans‐Georg 
Published: October 2010

AbstractEs werden die wesentlichen Ergebnisse zur Untersuchung der Baugrubenverformungen in weichen Böden bei spanungspfadabhängigem Materialverhalten anhand von 1g‐Modellversuchen, Elementversuchen, numerischen Berechnungen sowie Validierungen an drei Fallbeispielen vorgestellt. Wesentliche neue wissenschaftliche Erkenntnisse resultieren insbesondere aus spannungspfadabhängigen Triaxialversuchen. Die bodenmechanischen Kenngrößen sind danach eindeutig spannungspfadabhängig.Darüber hinaus wird eine verbesserte, unmittelbar in der Ingenieurpraxis anwendbare Vorgehensweise zur Berücksichtigung der spannungspfadabhängigen Steifigkeit vorgestellt, die für zukünftige Projekte bei vergleichbaren Randbedingungen besser abgesicherte Prognosen der Beanspruchungen und besonders der zu erwartenden Verformungen ermöglichen.Deformations of excavations in soft soils with stress‐path‐dependent material behavior. The substantial results of a research work on deformations of excavations in soft grounds with stress path dependent material behavior on the basis of 1g‐model tests, element tests, numerical analysis as well as validations of three practical case studies are presented. The investigations revealed a pronounced dependency of the stiffness on the stress paths.Therefore, a new approach for numerical analyses is introduced which allows a consideration of the stress path dependent stiffness according to the characteristic stress path zones. Taking into account both temporal and spatial effects in the construction of the three case studies, a good agreement is reached further between the measurements and numeriod results. Thus, the new approach contributes to the optimization of the analysis of excavations in soft soils.
Das Magnitude 8.8 Maule (Chile)‐Erdbeben vom 27. Februar 2010 — Ingenieuranalyse der Tsunamischäden, Teil 2

Published: October 2010

AbstractDas Maule (Chile)‐Erdbeben vom 27. Februar 2010 gehört zu den stärksten, weltweit jemals registrierten Erdbeben. Das seismische Ereignis löste einen Tsunami aus, der durch mehrere Wellenfronten verheerende Schäden an der Küste Chiles verursachte.Ereignisspezifische Besonderheiten aus der überlagerung der Effekte aus Erdbeben und darauffolgenden Flutwellen (Tsunami) waren Motivation, im Rahmen einer Erkundungsmission der Ingenieurgruppe der Deutschen Task Force im betroffenen Gebiet die Bauwerksschäden aufzunehmen und ihre regionale Verteilung zu dokumentieren. Der Beitrag vermittelt einen Eindruck von den durch den Tsunami bedingten Schäden; es wird der Versuch unternommen, das Verhalten der typischen Bauweisen unter den zeitlich sequentiell auftretenden extremen Einwirkungen aufzuzeigen. Die Auswertungen schließen an die Ingenieuranalyse der Erdbebenschäden an, so dass auf die im vorangegangenen 1. Teil des Beitrags vom August 2010 [1] gegebene allgemeine übersicht zum Gebäudebestand in Chile und zur Typisierung der Bauweisen verwiesen werden kann. Die Schäden aus dem Tsunami konzentrieren sich auf die eher ländlichen und ohnehin weniger tauglichen traditionellen Bauweisen in den Küstenregionen. An den wesentlichen Wirkungsmechanismen eines Tsunami werden die Verletzbarkeit der Bauweisen und die Effizienz einfacher baulicher Schutzmaßnahmen herausgearbeitet. Wie gezeigt werden kann, tragen Schäden aus Treibgut erheblich zum Schadensbild bei.The Magnitude 8.8 Maule (Chile) earthquake of February 27, 2010 — Engineering analysis of tsunami damages. The Maule (Chile) February 27, 2010 earthquake is regarded as one of the strongest earthquakes ever recorded world‐wide. The seismic event triggered a tsunami which caused by several wave fronts serious damage alongside the coastal border.Event‐specific characteristics from the overlay of the effects from earthquakes and following flood wave (Tsunami) were motivation to examine building damage and to document their regional distribution, in the context of a reconnaissance mission of the engineering group of the German Task Force for earthquakes. The paper provides an impression from the tsunami induced damage to the different building types under the impact of time‐varying sequence of extreme natural events. First results of the studies in [1] are related to the engineering analysis of earthquake damage. Therefore it can be referred to the overview of the building stock and the predominant structural systems in Chile given there. Damage caused by the tsunami is concentrated on rural and often less resistant traditional buildings in coastal areas. The main loading and impact components induced by the tsunami are used to explain the vulnerability of building types and the efficiency of simple structural measures. As the damage cases demonstrate, debris in its general sense has contributed to the observed effects.

Published: October 2010

AbstractPercutaneous patent ductus arteriosus (PDA) closure is a safe and feasible treatment, and it is recommended over surgical approach in the majority of cases. Amplatzer duct occluder (ADO—AGA Medical Corporation, Golden Valley, MN) is the preferred device for transcatheter treatment of PDA. Recently, the ADO II (AGA Medical Corporation, Golden Valley, MN), allowing PDA closure through a small delivery catheter from an antegrade or retrograde approach, received the European Community mark approval. Here, we report, for the first time, successful PDA closure in a 66‐year‐old female with the ADO II device, using a transradial approach. © 2010 Wiley‐Liss, Inc.
