Quick and efficient processing of images is an important request of various disciplines and several applied fields. Many authors have studied specialized computing architectures (with electronic technology) devoted to image processing (see, for example, Refs. 1-5), but other authors have pointed out that optical computing architectures are more suitable for massive computation on images because...

Measuring responsiveness to gain accurate diagnosis in populations with disorders of consciousness (DOC) is of central concern because these patients have such complex clinical presentations. Due to the uncertainty of accuracy for both behavioral and neurophysiological measures in DOC, combined assessment approaches are recommended. A number of standardized behavioral measures can be used with ...

Effects of fire on biogeochemical cycling in terrestrial ecosystem are widely acknowledged, while few studies have focused on the bacterial community under the disturbance of long-term frequent prescribed fire. In this study, three treatments (burning every two years (B2), burning every four years (B4) and no burning (B0)) were applied for 38 years in an Australian wet sclerophyll forest. Resul...

the double object and the to-dative constructions. It is well known that the two differ semantically and syntactically. In some recent works, it is suggested that the semantic differences observed by Bresnan (1978), Oehrle (1976) and others, and the structural properties noted by Barss and Lasnik (1986), Larson (1988), and others, can both be captured by postulating an extra head for the Double...

OBJECTIVE To determine the light intensity emitted by light curing units (LCUs) and its effect on the cure characteristics of composites polymerised with it. DESIGN A laboratory based cross sectional study. SETTING Public and private dental clinics in Nairobi, Kenya. RESULTS Thirty five (42.17%) LCUs produced light of intensity ≤300mWcm⁻² while 43 (51.8%) LCUs had their intensities betwee...

Abstract. The temporal evolution of the characteristics of Denmark Strait Overflow Water (DSOW) is reconstructed using hydrographic data and compared with possible atmospheric forcing mechanisms. It is concluded that the main factor influencing the DSOW characteristics at a time scale of one to several years is the difference in mean sea level pressure across Denmark Strait or, in other words, ...

During the processes of primary succession and soil development, large stocks of organic C with very long residence times accumulate in many soils. Soluble organic C adsorbed by soils may contribute to the stock of organic C accumulating during soil development. We determined whether the mineralization rate of water-soluble organic C and the insoluble residue from C-labelled leaf litter added t...

BACKGROUND To test the value of a simulated Family Conference Objective Structured Clinical Exam (OSCE) for resident assessment purposes, we examined the generalizability and construct validity of its scores in a multi-institutional study. METHODS Thirty-four first-year (PG1) and 27 third-year (PG3) surgery residents (n = 61) from 6 training programs were tested. The OSCE consisted of 2 cases...
