Viability of wall-embedded tag antenna for ultra-wideband real-time suitcase lo...

WOS:000335152600007 (Nº de Acesso Web of Science) ; Viability of a conformal single-layer monopole antenna is studied for a wall-embedded tag in an ultra-wideband (UWB) suitcase localisation application based on impulse radio UWB. The performance of the embedded antenna is simulated and confirmed experimentally in real-time localisation (RTL) experiments carried out in a cluttered laboratory environment. Evalu...

Long-term memory in financial prices: evidence from the Dutch stock market returns

Prepared for presentation at the Portuguese Finance Network International Conference 2014, Vilamoura, Portugal, June 18-20 ; The purpose of this paper is to contribute to the discussion of long-term memory, focusing on the behavior of the main Dutch stock index.The analysis of the general characteristics of temporal frequency reveals that daily returns are non-ergodic, non-stationary and non-independent. Conse...

Tumor regression grades: can they influence rectal cancer therapy decision tree?

BACKGROUND: Evaluating impact of tumor regression grade in prognosis of patients with locally advanced rectal cancer (LARC). MATERIALS AND METHODS: We identified from our colorectal cancer database 168 patients with LARC who received neoadjuvant therapy followed by complete mesorectum excision surgery between 2003 and 2011: 157 received 5-FU-based chemoradiation (CRT) and 11 short course RT. We excluded 29 pati...

Psychotic aura symptoms in familial hemiplegic migraine type 2 (ATP1A2)

Abstract INTRODUCTION: Neuropsychological symptoms are rare in familial hemiplegic migraine (FHM). There are no reports of psychotic symptoms in FHM type 2 (ATP1A2). We examined a family with a FHM phenotype due to a M731T mutation in ATP1A2. A 10-year follow-up allowed us to observe complex auras, including psychotic symptoms in two siblings. CASE REPORT: Male, 48 years old, with an aura that included complex...

Genetic Characterization of an Insect-Specific Flavivirus Isolated from Culex T...

We describe the full genetic characterization of an insect-specific flavivirus (ISF) from Culex theileri (Theobald) mosquitoes collected in Portugal. This represents the first isolation and full characterization of an ISF from Portuguese mosquitoes. The virus, designated CTFV, for Culex theileri flavivirus, was isolated in the C6/36 Stegomyia albopicta (=Aedes albopictus) cell line, and failed to replicate in v...

Aluminum and Sulphate Removal by a Highly Al-Resistant Dissimilatory Sulphate-R...

A highly Al-resistant dissimilatory sulphatereducing bacteria community was isolated from sludge of the wetland of Urgeiriça mine (community W). This community showed excellent sulphate removal at the presence of Al3+. After 27 days of incubation, 73,86 and 81% of sulphate was removed in the presence of 0.48, 0.90 and 1.30 mM of Al3+, respectively. Moreover,Al3+ was simultaneously removed: 55,85 and 78% of meta...

Design and Characterization of a 20 Gbit/s Clock Recovery Circuit

In this communication we report the design of a clock recovery circuit produced for the 20 Gbit/s demonstrator of the RACE 2011 project "TRAVEL" of the European Community. The clock recovery circuit is based on an open loop structure using a dielectric resonator narrow bandpass filter with high Q.A detailed electrical characterization of the circuit and alsoits sensitivity to temperatur...
