Mapping of the zenith hydrostatic delay at radio frequencies to elevations as low as 3° has been improved by making use of the in situ atmosphere state. This information might be obtained from a numerical weather model, thus providing better atmosphere calibration on a global scale. The new model has been evaluated by comparing the repeatability of the lengths of baselines measured by Very Long...

This paper studies inference on fixed effects in a linear regression model estimated from network data. We derive bounds on the variance of the fixed-effect estimator that uncover the importance of the smallest non-zero eigenvalue of the (normalized) Laplacian of the network and of the degree structure of the network. The eigenvalue is a measure of connectivity, with smaller values indicating l...

A simple and rapid stability indicating method based on capillary zone electrophoresis has been developed and validated for the analysis of buserelin (BUS). The best separations were achieved by using a bare fused silica capillary (75 m i.d.; 65.5 cm total, 57.0 cm effective length), phosphate buffer (pH = 3.00; 26.4 mM), at 35 °C. The sample was hydrodynamically injected at 50 mbar for 5 seco...

This paper proposes an emotion recognition system using EEG signals, therefore a new approach to emotion state analysis by approximate (ApEn) and wavelet entropy (WE) is described. We have used EEG signals recorded during emotion in five channels (FP1, FP2, T3, T4 and Pz), under pictures induction environment (calmneutral and negative excited) for participants. After a brief introduction to the...

The present study investigated the effect of Parkinson's disease (PD) on prospective memory (PM) tasks by varying the emotional content of the PM actions. Twenty-one older adults with PD and 25 healthy older adults took part in the present study. Participants performed three virtual days in the Virtual Week task. On each virtual day, participants performed actions with positive, negative or neu...

For the determination of assay voriconazole in bulk and pharmaceutical dosage forms, a novel stability indicating RP-HPLC method was designed validated, exhibiting very low run time. The stability-indicating nature approach is supported by fact that it unique, quick, precise, accurate, capable isolating peak from any contaminating or degrading components. Isocratic elution on 100 mm x 4.6 mm, 3...

Background: Although theory explains the development of illness script, it does not provide answers how medical students develop scripts in their learning. To fill the knowledge gap of developing illness script in medical students and interns, this study aimed to investigate the impact of educational strategies inspired by theory in the development of illness scripts.    Methods: A total of 15...

In the early days of email, widely-used conventions for indicating quoted reply content and email signatures made it easy to segment email messages into their functional parts. Today, the explosion of different email formats and styles, coupled with the ad hoc ways in which people vary the structure and layout of their messages, means that simple techniques for identifying quoted replies that u...
