Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages each node sends out periodically. Due to mobility, the information that a node receives about its neighb...

OBJECTIVE To identify potential risk factors for cesarean delivery following labor induction in multiparous women at term. METHODS We conducted a retrospective case-control study. Cases were parous women in whom the induction of labor had resulted in a cesarean delivery. For each case, we used the data of two successful inductions as controls. Successful induction was defined as a vaginal del...

Penetration of the subarachnoid space by fetal scalp electrode Fetal scalp electrodes of various designs are used widely for continuous intrapartum fetal heart rate monitoring. Minor lacerations of the scalp are common, and 1-0-4-5% of infants may develop scalp ulceration or abscess.1 2 We describe two cases in which there was penetration of the subarachnoid space with leakage of cerebrospinal ...

There is a clear dose response for localized prostate cancer radiotherapy and there probably is a radiobiological rationale for hypo-fractionation. Combining the two should maximize tumor control and increase the therapeutic ratio. This study examines the rationale and technical feasibility of CyberKnife radiotherapy (a robotic arm-driven linear accelerator) for localized prostate cancer. Its a...

High-level control systems are designed to enable mobile robots to successfully perform complex missions such as ooce delivery and surveillance tasks. For that purpose they have to control, coordinate, and monitor diierent kinds of subtasks like navigation, manipulation, and perception. An important aspect of the eeec-tiveness of high-level control systems is the ability to cope with failures t...

Recent developments of wireless communication systems have resulted in the availability of heterogeneous access networks at any geographic area. To make use of this heterogeneous environment for vehicular users to access the Internet, in this article we propose a hybrid multi-technology routing (HMTR) protocol for multihop vehicular networks. HMTR takes into account different combinations of wi...

The product delivery system is normally powered by a DC motor. Permanent magnet brushless DC motor small sized, high power density, simple structure, is currently being widely used in a variety of transmission systems. In this paper, a permanent magnet motor position sensorless actuator for the production of a delivery system is studied. The actuator position control algorithm of the EGR system...

Protein drugs have attracted considerable attention as therapeutic agents due to their diversity and biocompatibility. However, hydrophilic proteins possess difficulty in penetrating lipophilic cell membrane. Although protein transduction domains (PTDs) have shown effectiveness in protein delivery, the importance of selection and position of PTDs in recombinant protein vector constructs has not...

Localization and verification of a tumor position was conventionally performed prior to radiotherapy. The present authors, in the past a few years, proposed in-treatment verification of the tumor position by simultaneously acquiring cone beam computed tomography (CBCT) data using an on-board kilovolt imaging system. Dose delivery was either rotational conformal 1) or volumetric modulated arc th...
