Re-annotation of the Campylobacter jejuni NCTC11168 genome and functional characterisation of selected genes involved in strain pathogenesis

Ozan Gundogdu
Campylobacter jejuni is the leading bacterial cause of foodborne human gastroenteritis worldwide. The first C. jejuni genome (strain NCTC11168) was sequenced in 2000. This original annotation was a milestone in Campylobacter research, but soon became outdated. A re-annotation and re-analysis of this genome sequence was performed resulting in updates to over 90% of coding sequences (CDSs) and modification of 18.2% of CDS product functions (Gundogdu et al., 2007). Following this re-annotation, 15 uncharacterised CDSs with...

Employing Reverse Polish Notation In Encryption

Dr.S.S. Dhenakaran
ABSTRACT Cryptosystem is one of the effective principles helpful to internet aspirants to send message safely to the respondents. This principle ensures reliability for the message to be sent over internet. The basic requisite of the method is transforming the original message into some other stream to hide the syntax and semantics of the message before transmitting over internet. This paper is proposed to carry the job of perplexing the input message before applying the...

Battery-less sensor nodes for 802.15.4/ZigBee wireless networks

Marcel Meli & Marcel Da Silva
Battery-free wireless sensor nodes are very convenient in many applications. They eliminate the costs associated with installing batteries and reduce maintenance headaches. For these reasons, they are gaining in popularity. Such devices usually require the use of an energy source that harvest power from the surroundings. Because of the necessity of harvesting energy and the related costs, there are limitations to the kind of application and wireless protocol that can successfully be implemented, especially when...

Indoor battery-less temperature and humidity sensor for Bluetooth Low Energy

Urs Beerli & Marcel Meli
In June 2010, the Bluetooth SIG adopted the first version of Bluetooth that includes the low energy specifications (4.0). Ble has been designed to allow devices running on a small energy budget to communicate with host stations such as mobile phones or personal computers. Bluetooth low energy is primarily meant to be used in applications that require small batteries. In this work we investigated the suitability of that new wireless protocol for a battery-free application....

"Si fier tornei": Benoîts ‚Roman de Troie‘ und die höfische Kultur des 12. Jahrhunderts

Solveig Kristina Malatrait
Die Darstellung Trojas ist selbstverständlicher Teil des gelehrten Wissens im 12. Jahrhundert, das unter anderem durch Verehrung, aber auch durch Aneignung der Antike gekennzeichnet ist. Benoît de Sainte-Maure's „Roman de Troie“ erfuhr eine breite und intensive zeitgenössische Rezeption. Eine erste kritische wissenschaftliche Würdigung des „Roman de Troie“ lieferte Aristide Joly 1870/71. Nach nun beinahe 140 Jahren legt Solveig Malatrait eine Monographie vor, die das Meisterwerk der altfranzösischen Epik aus kulturwissenschaftlicher Perspektive neu betrachtet.

Wirksames Karriere-Coaching: Ein Grundlagenmodell

Andreas Hirschi
This paper presents a theory- and research-based model for career coaching. It distinguishes four main areas of career coaching contents: (1) self-knowledge; (2) occupational and career knowledge; (3) career decision-making and career planning skills; (4) attitudes towards oneself and one’s career. The four content areas are addressed in a four-phase process (1) communication: problem analysis and establishment of coaching relationship; (2) analysis: working on the causes of the career concern; (3) synthesis/evaluation: developing and evaluation...

Adaptation and Evaluation of a German Sign Language Test

Tobias Haug
Despite the current need for reliable and valid test instruments to monitor the sign language acquisition of Deaf children in different countries, very few tests offering strong evidence for their psychometric properties are commercially available. A German Sign Language (DGS) test that focuses on linguistic structures acquired in preschool- and school-aged children (4–8 years old) is urgently needed. The present study uses as a template a test which has sound psychometric properties and has been...

UNLABELLED The objective of this study was to compare MRI response assessment with metabolic O-(2-(18)F-fluoroethyl)-L-tyrosine ((18)F-FET) PET response evaluation during antiangiogenic treatment in patients with recurrent high-grade glioma (rHGG). METHODS Eleven patients with rHGG were treated biweekly with bevacizumab-irinotecan. MR images and (18)F-FET PET scans were obtained at baseline and at follow-up 8-12 wk after treatment onset. MRI treatment response was evaluated by T1/T2 volumetry according to response assessment in neurooncology (RANO) criteria. For (18)F-FET...

Assistance or challenge? Filling a gap in user-cooperative control

Roland Sigrist, Georg Rauter, Laura Marchal Crespo, Peter Wolf, Robert Riener & Heike Vallery
Nowadays, “user-cooperative” control strategies are commonly used in robot-assisted motor (re-)learning. User-cooperative strategies enable compliant haptic interactions between robot and user: the robot only intervenes as needed, instead of forcing the user to follow a fixed predefined movement. However, the effectiveness of user-cooperative control is contro-versially discussed. Recent studies indicate that the effectiveness of user-cooperative control strategies will be enhanced when every user is individually provided with an optimal amount of assistance or challenge. In...

An fMRI pilot study to evaluate brain activation associated with locomotion adaptation

Laura Marchal Crespo, C. Hollnagel, M. Brugger, S. Kollias & Robert Riener
The goal of robotic therapy is to provoke motor plasticity via the application of robotic training strategies. Although robotic haptic guidance is the commonly used motor-training strategy to reduce performance errors while training, research on motor learning has emphasized that errors are a fundamental neural signal that drives motor adaptation. Thus, researchers have proposed robotic therapy algorithms that amplify movement errors rather than decrease them. Studying the particular brain regions involved in learning under different...

Towards a BCI for sensorimotor training: Initial results from simultaneous fNIRS and biosignal recordings

O. Lambercy, M. Wolf, R. Zimmermann, Marie-Christine Fluet, Robert Riener, Laura Marchal Crespo & Roger Gassert
This paper presents the concept and initial results of a novel approach for robot assisted sensorimotor training in stroke rehabilitation. It is based on a brain-body-robot interface (B2RI), combining both neural and physiological recordings, that detects the intention to perform a motor task. By directly including the injured brain into the therapy, we ultimately aim at providing a new method for severely impaired patients to engage in active movement therapy. In the present study, seven...
