Capacity measurements for a 16/spl times/16 element BLAST array over a conducting ground plane

The paper presents channel transfer function measurements using a 16/spl times/16 "Bell Laboratories layered space-time" (BLAST) antenna array and a wideband measurement system. The capacity of a BLAST system is computed using the H matrix, comprised of the complex transfer functions between each transmitter and receiver element. Measurements were made over a metallic ground plane to allow comparison with an analytical calculation of the H matrix. Using this comparison, it was determined how accurately the H matrix can be measured using a wideband system and hence how accurately the capacity of the BLAST system can be predicted. It was found that the predicted capacities, based on measurements using the 16/spl times/16 system, were within 5% of the theoretical calculations.
Trichom-Entwicklung in Arabidopsis thaliana als Modellsystem für de novo Musterbildungsprozesse

Die Trichom-Musterbildung in Arababidopsis thaliana stellt ein etabliertes Modellsystem zur Untersuchung von Musterbildungsprozessen in Pflanzen dar. Die Trichom-Entwicklung wird von bHLH- und MYB-Transkriptionsfaktoren zusammen mit einem WD-40 Protein reguliert. Zu den MYB-Transkriptionsfaktoren zahlen die Trichom-Inhibitoren TRY, CPC, ETC1, ETC2 und TCL1 und die Trichom-Aktivatoren GL1 und MYB23. GL3, EGL3 und TTG1, ebenfalls Trichom-Aktivatoren, kodieren fur bHLH- Transkriptionsfaktoren bzw. fur das WD-40 Protein. Die Trichom-Inhibitoren, auf die sich diese Arbeit konzentriert, regulieren nach der postulierten de novo Trichom-Musterbildung das regelmasige Abstandsmuster zwischen den Trichomen durch laterale Inhibition, was in dem Aktivator-Inhibitor Modell beschrieben wird. In dieser Arbeit wird gezeigt, dass ein weiteres Gen, ETC3 an der Regulation der Trichom-Musterbildung als Trichom-Inhibitor beteiligt ist. Untersuchungen der Trichom-Inhibitoren auf Proteinebene zeigen neue Aspekte der lateralen Inhibition durch deren Mobilitat. Durch Kompetitionsanalysen wird gezeigt, dass die Inhibitoren ETC1, ETC3, CPC und TRY am Mechanismus der lateralen Inhibition durch die Verdrangung von GL1 aus dem Aktivator Komplex beteiligt sind, wohingegen ETC2 keine Kompetitor-Eigenschaft besitzt. Weiterhin wird anhand von CPC und ETC3 gezeigt, dass die Inhibitoren unterschiedliche Signalreichweiten fur die laterale Inhibition besitzen, die aufgrund unterschiedlicher Bindungsaffinitaten zu GL3 erklart werden. Fur diese Beobachtung wird ein theoretisches Modell postuliert, nach dem ETC2 die langste Signalreichweite der Inhibitoren besitzt, gefolgt von ETC3 und TRY. CPC und ETC1 haben nach diesem Modell lediglich eine kurze Signalreichweite. Auf Expressionsebene werden Unterschiede zwischen den Promotoren von CPC, TRY und ETC3 aufgezeigt. Weiterhin werden die Inhibitoren CPC und TRY auf eine mogliche posttranslationale Phosphorylierung untersucht um eine eventuelle Regulation der inhibitorischen Aktivitat und/oder der Mobilitat aufzudecken. Weiterhin wird eine Methode vorgestellt, die es ermoglicht, die Trichom-Musterbildung in Rosettenblattern von der Entstehung der Trichom-initialzellen bis hin zum adulten Stadium in vivo zeitlich zu verfolgen. Daraus ergibt sich einerseits eine neue Moglichkeit, die Musterbildung quantitativ in silico zu analysieren. Auserdem dient diese Methode der in vivo Verfolgung dazu, die postulierte de novo Musterbildung durch Laser-Ablationen zu verifizieren.
Conversational coherence and gesture

The present study claims that the use of spontaneous gestures can contribute to accomplishing coherence in sequential conversational exchanges. Three types of speech-accompanying gestures were analyzed in Chinese conversation. Based on the syntactic-semantic relation with the co-occurring utterance, the first type is associated with words that do not convey explicit meaning; the second type is associated with covert constituents; the third type does not have any linguistic affiliates. They suggest different ways in which gesture adds information to the propositional content of the associated utterance or to the content of the speech event under discussion. They also play a role in achieving conversational coherence: on the part of the speaker, it is only by using the various types of gesture that a current speaker can make the message to be conveyed in the utterance complete. On the part of the next speaker, the recognition and negotiation with the former speaker of the gestured information is a way to acknowledge or confirm mutual knowledge. The collaborative efforts contribute to the coherence of the talk in the subsequent interaction.
Evaluatie Agrarisch Natuurbeheer: effecten op weidevogeldichtheden

Het huidige beleid om weidevogels te beschermen is niet erg effectief. Dit blijkt uit een omvangrijk onderzoek van Wageningen Universiteit, SOVON en Alterra. Het aantal grutto's neemt niet toe en de populatie kieviten gaat zelfs achteruit. De onderzoekers concluderen echter niet dat boeren moeten stoppen met de beheersovereenkomsten. Het lijkt er juist op dat er meer moet worden gedaan

Pruning the verb class tree: issues of granularity in classifying verbs of communication

In this paper we will present an alternative classification of verbs of communication, as they are discussed in Levin (1993), Baker, C. & J. Ruppenhofer (2002) and Barðdal (2003), a.o. More specifically, we will use recent research results (Verroens et al. 2008) on the subcategory of Verbs of Instrument of Communication (i.e. (tele)phone, wire, fax, etc.) to tackle the problem of granularity in verb typologies in general and the impact and implications it has for the classification of verbs of communication in particular. In an attempt to group those verbs that show similarities both with respect to types of constructions as well as their attested frequency, a different system of clustering will be presented on the basis of the structure of the matrix event (following Pustejovsky 1988, 1998) and the position that is assumed by the verbs in this constellation. In the first part of the paper we zoom in on the micro-level and discuss the Verbs of Instrument of Communication (VICs) as a subcategory of the more general class of Verbs of Communication in both French and English. The findings of Verroens et al. (2008) are relevant with respect to the issue of granularity in at least two ways. First, despite their being derived from the instrument that is used to communicate and despite the attested similarities, corpus data shows that these verbs actually differ significantly in terms of structural possibilities and the frequency with which these have been attested. Based on the realised arguments and the kinds of themes, for instance, it can be concluded that fax, telegraph, wire, mail behave relatively similarly and that skype, blackberry, cell and telephone show overlap in structural preferences as well. In terms of classification the structural differences between these two groups are actually more striking and relevant than their being derived from an instrument. Secondly, the study reveals that some ‘new’ Verbs of Instrument of Communication (e.g. skype, blackberry, text, etc.), which can be added to Levin’s (1993) list, allow for structural possibilities that do not occur in any of the other VICs, but which can be attested in other verbs of communication, not belonging to this category. For instance, while phone with and fax with have not been attested in the English data, skype with seems to be perfectly acceptable, as shown in (1), a structure which is also possible for chitchat verbs and talk verbs.
Usefulness of CT Perfusion Imaging in Adult Moyamoya Disease

Purpose: The purpose of this study was to evaluate the role of perfusion CT in adult moyamoya disease. Materials and Methods: The study population consisted of 13 adult moyamoya patients (10 women and 3 men, mean age: 40.4 years) and 11 age-matched normal controls (5 men and 6 women, mean age: 43 years). We ret-rospectively assessed the perfusion CT scan both visually and by a quantitative regional analysis, and we assessed the relationship between the perfusion CT scan findings and the angiographic findings. Results: The mean relative cerebral blood volume (rCBV) values in moyamoya patients were 8.0% for the MCA area, 6.4% for the PCA area, and 7.7% for the basal ganglia. The rCBV values in the patients were higher than those in the control group with statistical significance ( p <0.0001). The time to peak enhancement (TTP) values of the MCA area and the basal ganglia were delayed more than those in the controls; this was statistically significant ( p <0.05). Moderate correlation was found between the rCBV in the basal ganglia area and angiographic stage of the basal moyamoya vessels. Conclusion: Perfusion CT demonstrates a statistically significant increase in rCBV in the MCA, PCA and basal ganglia areas and the TTP in the MCA and basal ganglia areas in patients with moyamoya disease. The visual brain perfusion patterns correlate with the extent and severity of the basal moyamoya vessels.
Induction with randomization testing: decision-oriented analysis of large data sets

Induction systems are computer-based tools that aid the construction of useful models from data. Existing systems are subject to overfitting--a tendency to produce models with unnecessary structure. Accurate statistical significance testing could prevent overfitting, but nearly all existing statistical significance tests are not appropriate for induction systems. One approach, randomization testing, can be extended to meet the challenges posed by induction systems. Experiments indicate that a system with randomization testing can successfully combat overfitting. Models produced by the system are as accurate as, but significantly simpler than, models produced by other systems.
Évaluation dosimétrique et biogénotoxicologique de l'exposition aux rayonnements ionisants

Le Laboratoire de Biogenotoxicologie et Mutagenese Environnementale a pour objectifs la detection precoce des effets genotoxiques des nuisances environnementales, la validation de biomarqueurs et la biosurveillance de salaries exposes a un environnement professionnel potentiellement cancerogene. Les travaux menes par le laboratoire dans le domaine des rayonnements ionisants, associant mesures environnementales et evaluation de la genotoxicite dans un objectif de prevention, concernent les travailleurs exposes en radiographie industrielle et en milieu hospitalier. La caracterisation des expositions repose ainsi sur l'analyse des activites avec dosimetrie physique, le recueil des enregistrements dosimetriques et la mise en œuvre de biomarqueurs d'effets genotoxiques tels que le test des micronoyaux sur lymphocytes, permettant de detecter des remaniements chromosomiques de structure ou de nombre. Les donnees d'analyse de poste associees a des modelisations ont egalement permis d'etablir un tableau de doses de reference, pour chaque etape constitutive d'un tir en gammagraphie industrielle, ce qui constitue un outil interessant pour la dosimetrie previsionnelle.

A New Solution to Defend Against Cooperative Black Hole Attack in Optimized Link State Routing Protocol

In Mobile Ad Hoc Networks (MANETs), mobile nodes use wireless devices to create spontaneously a larger network. These nodes communicate with each other by the means of routing protocols. One of this routing protocol is OLSR [1] (Optimized Link State Routing Protocol) which assumes that all nodes are trusted. However, in hostile environnement, the OLSR is known to be vulnerable to various kinds of malicious attacks. This paper proposes a collusion attack against MANETs exploiting vulnerabilities of OLSR. In this attack, two attacking nodes cooperate in order to disrupt the topology discovery and prevent routes to a target node from being established in the network.
Errors and Truths from Transportation Data Aggregation: Some Implications for Research and Practice

Harmonic mean, which is the reciprocal of the arithmetic mean of the reciprocals of observations, is considered to be an appropriate average for rates or ratios. In transportation, the harmonic mean is used to calculate Space Mean Speed, where a designated segment length is fixed or passing vehicles are assumed to complete the segment with given speeds. This study identifies and proves a sampling bias of harmonic mean, which definitively affects the sampling bias of the space mean speed on the fixed segments. The study shows, a mathematical proof and numerical example, that harmonic mean is overestimated when the sample size is smaller than the population. The study also provides both analytical and simulation-based correction approach. From the simulations and the three case studies of investigating the impact of the sampling bias in this study, it is recognized that the sampling bias is affected by sampling rate, time interval, segment length, and distribution type.
Evacuation Plan Evaluation: Assessment of Vehicular Evacuation Schemes by means of an Analytical Dynamic Traffic Model

Binnen dit thesis rapport bespreken we een generieke methode voor het evalueren van verschillende typen evacuatie schema’s. Daartoe wordt eerst de theorie over evacuatie (gedrag) samengevat. Bij de theorievorming bespreken we de voornaamste aspecten welk invloed uitoefenen op het keuzegedrag van de evacues. Het betreft dan de keuzen om deel te nemen aan de evacuatie, en (eventueel) het vertrektijdstip, de veilige bestemming en de evacuatie route. De theorie wordt gebruikt als basis voor het beschreven evacuatie model. Het evacuatie model bestaat uit drie componenten, welk respectievelijk de dynamische vervoersvraag, het adaptieve en-route reis keuze gedrag en de dynamische verkeersafwikkeling modelleren. De dynamische vervoersvraag component en de adaptieve en-route reis keuze gedrag component modelleren de evacuatie participatie en vertrektijdstip keuze, respectievelijk de evacuatie bestemming en route keuze. De afwikkeling van de verkeersstromen wordt dan gemodelleerd door de macroscopische dynamisch verkeersafwikkeling component, gebaseerd op de dynamische calamiteit en verkeerscondities. Zoals eerder genoemd, kan met het beschreven model verschillende typen evacuatie schema’s geevalueerd worden. Naast het varieren van de evacuatie instructies (vertrektijdstip, bestemming en route), zijn ook verschillende typen instructies mogelijk. Het type instructies varieert dan van aanbevelingen tot bindende instructies (bevelen). Binnen het beschreven evacuatie model is het waarschijnlijke gedragsrespons van de evacues realistischer, aangezien er rekening wordt gehouden met het denkbeeld en de wensen en intenties van de evacues. Daardoor is het mogelijk dat evacuatie instructies (gedeeltelijk) gevolgd worden, of genegeerd worden door de individuele evacues. Het model is in staat om te gaan met een calamiteit dat toeslaat voordat de evacuatie is begonnen, of toeslaat tijdens de evacuatie. In deze gevallen, kan de calamiteit de evacues in gevaar brengen en de evacuatie hinderen. Het hinderen van de evacuatie gebeurt doordat de calamiteit ervoor zorgt dat delen van het netwerk ontoegankelijk worden. Door de mogelijke netwerk versperringen te simuleren, kan de autoriteit het effect ervan anticiperen en zo nodig het evacuatie schema aanpassen. Tot slot kunnen we stellen dat het beschreven evacuatie model mogelijk een autoriteit kan assisteren bij het zoeken naar het meest geschikte evacuatie schema. Om de potentie van het beschreven model te illustreren in het plannen van grootschalige evacuaties, is het model geprogrammeerd in Matlab en toegepast op een hypothetische bosbrand evacuatie in de Berowra Valley, ten noorden van Sydney, Australie.
A study on General Obstacle Detection by Spatio-Temporal Subtraction with Past In-Vehicle Camera Image Sequence

The aim of this research is to detect forward obstacles from front-views of in-vehicle camera images. Most existing techniques detect specific obstacles, such as a pedestrian or a vehicle. Thus, they can’t detect unexpected obstacles on the road. By using subtraction, unexpected obstacles can be detected without the previous knowledge about them. First, the proposed method computes the correspondences between the present and the past in-vehicle camera images. Next, the proposed method compensates the gap of the road-surface regions caused by the different running positions, and determines the correspondence of the road-surface regions. Then, obstacles are detected by using spatio-temporal subtraction technique. Experiments were conducted using in-vehicle camera images. The results showed that the proposed method could detect various obstacles on the road satisfactorily.
Commercial Vehicle Travel Time Estimation in Urban Networks using GPS Data from 1

1 Realistic travel time estimation for urban commercial vehicle movements is challenging due to 2 limited observed data, large number of Origin-Destination (OD) pairs, and high variability of 3 travel times due to congestion. Moreover most traditional data collection methods can only 4 provide information in an aggregated form which is not sufficient for micro-level analysis. On 5 the other hand, the usage of Global Positioning Systems (GPS) data for traffic monitoring and 6 planning has been continuously growing with significant technological advances in the last two 7 decades. 8 In this paper we provide a comprehensive review of the current usage of GPS data in 9 transportation planning applications and present a practical integrated methodology for using a 10 robust source of GPS data, for commercial vehicle travel time prediction. A comparison with 11 observed truck travel times collected from a limited source of truck-GPS data reveals that travel 12 times obtained from taxi-GPS data approximate those of trucks, and can be used to supplement 13 truck-GPS travel time data on a wider scale. While the amount of truck-GPS data is limited to a 14 small number of trucks serving very few OD pairs, taxi-GPS provide citywide penetration and 15 can estimate travel times between most OD pairs in a city. The provided methodology leads to 16 simple and effective travel time estimations using taxi-GPS data without a need for an extra data 17 collection effort. 18 TRB 2013 Annual Meeting Paper revised from original submittal.
