Background. To evaluate the optical quality and related factors in patients with ocular hypertension (OHT). Methods. This was a prospective case-control study. A total of 12 eyes with OHT and 20 control eyes underwent testing with Optical Quality Analysis System II (OQAS II) to evaluate the modulation transfer function cut off frequency (MTF cutoff), the Strehl 2D ratio (SR), objective scatter ...

This paper analyses the associations between Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) on the prevalence of schistosomiasis and the presence of Biomphalaria glabrata in the state of Minas Gerais (MG), Brazil. Additionally, vegetation, soil and shade fraction images were created using a Linear Spectral Mixture Model (LSMM) from the blue, red and infrared c...

In this letter, we investigate the fundamental relationship between the performance of a maximum ratio diversity combining scheme and the normalized mean square covariance (NMSV) under wide-sense stationary uncorrelated scattering (WSSUS) channels. In particular, we show that the reliability achieved by diversity combining is closely related to the value of NMSV of the channel under consideration.

1. Patients in the pharmacistmanaged group spent a higher percentage of time in target therapeutic international normalised ratio range (64%) than those in the physicianmanaged group (59%). 2. Patients in the pharmacistmanaged group experienced a lower incidence of bleeding (1.6 events per 100 patient-years) than those in the physicianmanaged group (3.1 events per 100 patient-years). 3. Mean co...

The global International Financial Institutions (IFI’s) increasingly justify their operations in terms of the provision of International Public Goods (IPG’s). This is partly because there appears to be support among the rich countries of the North for expenditures on these IPG’s, in contrast to the “aid fatigue” that afflicts the channeling of country specific assistance. But do the IFI’s neces...

Recent evidence suggests that spectral change, as measured by cochlea-scaled entropy (CSE), predicts speech intelligibility better than the information carried by vowels or consonants in sentences. Motivated by this finding, the present study investigates whether intelligibility indices implemented to include segments marked with significant spectral change better predict speech intelligibility...

OBJECTIVE To examine anticoagulation management at the Bella Coola Medical Clinic in British Columbia. DESIGN Charts of all patients in the Bella Coola Valley receiving warfarin were assessed. Data were analyzed using Microsoft Excel. SETTING Bella Coola Medical Clinic on the remote central coast of British Columbia. PARTICIPANTS Twenty-one patients at the Bella Coola Medical Clinic who w...

Node definition is a very important issue in human brain network analysis and functional connectivity studies. Typically, the atlases generated from meta-analysis, random criteria, and structural criteria are utilized as nodes in related applications. However, these atlases are not originally designed for such purposes and may not be suitable. In this study, we combined normalized cut (Ncut) an...

BACKGROUND Warfarin prescription for anticoagulation after cardiac surgery has always been a challenge for junior medical staff. METHODS A prospective study was carried out to assess the quality of anticoagulation control by junior doctors compared with clinical pharmacists at South Manchester University hospitals NHS Trust. The junior medical staff prescribed warfarin for 50 consecutive pati...
