Research activities on umts radio interface network architectures and planning
IEEE Communications Magazine, 1998Co-Authors: E Berruto, M Gudmundson, R Menolascino, W Mohr, M PizarrosoAbstract:Currently worldwide activities are going on to define third-generation mobile radio systems (IMT-2000 on ITU/UMTS in Europe). These systems aim to support a wide range of services from voice and low-rate data up to high-rate data services, including multimedia services, and circuit- and packet-oriented services. These systems will operate in all radio environments to provide service to anyone, anytime, anywhere. In Europe the European Commission is partly Funding Research activities in the ACTS framework related to third-generation systems. A spectrum-efficient multiple access scheme proposal is being developed by the ACTS FRAMES project to fulfill the requirements for terrestrial third-generation mobile radio systems. The results and proposals of FRAMES are used as input mainly to the ETSI standardization process. This radio access scheme addresses the different worldwide standardization activities where TDMA and CDMA-based solutions are currently expected. Different proposals for the UMTS system architecture and network issues are currently being discussed in the relevant standardization bodies. On one hand, the GRAN approach envisages a single UMTS access part able to connect with multiple core networks; on the other hand, the generic core network approach proposes to develop UMTS core network functionality able to handle multiple access networks, which can adopt different types of radio access techniques. The ACTS RAINBOW project presents a proposal where both approaches are unified in a system structure. From the network planning viewpoint, the major features of a third-generation mobile system are the wide variety of services provided, the high number of customers expected (especially in urban and densely populated areas), the network architecture flexibility to allow different configurations to be deployed, and the advanced mobility management strategies. From this perspective the ACTS STORMS project is elaborating new planning methodologies tailored to the specific needs of a UMTS operator, and designing and developing a set of software modules covering the whole set of disciplines involved in mobile network planning.

long term cognitive and cardiac outcomes after prenatal exposure to chemotherapy in children aged 18 months or older an observational study
Lancet Oncology, 2012Co-Authors: Frederic Amant, Kristel Van Calsteren, M Halaska, Mina Mhallem Gziri, Lieven Lagae, M A A P Willemsen, Livia Kapusta, Ben Van Calster, Heidi Wouters, Liesbeth HeynsAbstract:Summary Background Chemotherapy for the treatment of maternal cancers during pregnancy has become more acceptable in the past decade; however, the effect of prenatal exposure to chemotherapy on cardiac and neurodevelopmental outcomes of the offspring is still uncertain. We aimed to record the general health, cardiac function, and neurodevelopmental outcomes of children who were prenatally exposed to chemotherapy. Methods We did an interim analysis of a multicentre observational cohort study assessing children who were prenatally exposed to maternal cancer staging and treatment, including chemotherapy. We assessed children at birth, at age 18 months, and at age 5–6, 8–9, 11–12, 14–15, or 18 years. We did clinical neurological examinations, tests of the general level of cognitive functioning (Bayley or intelligence quotient [IQ] test), electrocardiography and echocardiography, and administered a questionnaire on general health and development. From age 5 years, we also did audiometry, the Auditory Verbal Learning Test, and subtasks of the Children's Memory Scale, and the Test of Everyday Attention for Children, and we also completed the Child Behavior Checklist. This study is registered with ClinicalTrials.gov, number NCT00330447. Findings 236 cycles of chemotherapy were administered in 68 pregnancies. We assessed 70 children, born at a median gestational age of 35·7 weeks (range 28·3–41·0; IQR 3·3; 47 women at Interpretation Fetal exposure to chemotherapy was not associated with increased CNS, cardiac or auditory morbidity, or with impairments to general health and growth compared with the general population. However, subtle changes in cardiac and neurocognitive measurements emphasise the need for longer follow-up. Prematurity was common and was associated with impaired cognitive development. Therefore, iatrogenic preterm delivery should be avoided when possible.
