The interpretation of coronary angiograms is indispensable in determining procedure in coronary surgery. The aim of this study was to measure the overall reliability of a group of surgeons in the interpretation of coronary angiograms, surgical procedure and the evaluation of operative risk. Ten coronary angiograms were interpreted by eight cardiac surgeons at four different medical centers. Eva...

substantial movement is one of the most important sides of the gnostic geometry of the transcendental philosophy. in this writing, the notional aspect of the discourse and the way the substantial movement is based on the principality of existence is discussed. given the multiplicity of impressions from the principality of existence and the mentally-positedness (i‘tibāriyyat) of quiddity (māhiyy...

Localization under appearance changes is essential for robots during long-term operation. This paper investigates the problem of place recognition in environments that undergo dramatic visual changes. Our approach builds upon previous work on graph-based image sequence matching and extends it by incorporating a hashing-based image retrieval strategy in case of localization failures or the kidna...

Evidence for a substantial nuclear ordering in solid bcc Re3 at melting pressure has been inferred from solid entropies s s deduced from measurements of the slope of the melting curve for a liquid-solid mixture cooled by adiabatic compression. At 3.4 mK we find experimentally that ss/R = 0.S3ln2. It is likely that much lower temperatures and solid entropies are obtained during parts of the expe...

Personification of interface agents has been speculated to have several advantages, such as a positive effect on agent credibility and on the perception of learning experience. However, important questions less often addressed so far are what effect personification has on more objective measures, such as comprehension and recall, and furthermore, under what circumstances this effect (if any) oc...

The early tendon regenerate after an Achilles tendon rupture is a watery tissue, likely to show time-dependent deformation during load. To our knowledge the extent of such deformation has not previously been estimated in humans. Estimations of mechanical properties of intact tendons have usually applied ultrasonography1. This method measures the entire length of the tendon, and is therefore unl...

Ciphers get their strength from the mathematical functions of confusion and diffusion, also known as substitution and permutation. These were the basics of classical cryptography and they are still the basic part of modern ciphers. In block ciphers diffusion is achieved by the use of Maximum Distance Separable (MDS) matrices. In this paper we present some methods for constructing dynamic (and r...

The National Institutes of Health needs to make radical changes to ensure that biomedical research continues to thrive in the United States.

In 2009, 97 cases of listeriosis were reported in Denmark (1.8 per 100,000), a significant rise over the previous year. The increase was seen both in cases of bacteraemia and meningitis and affected mainly people aged 70 years and older. A foodborne outbreak of eight cases was identified by pulsed-field gel electrophoresis typing. No explanation has so far been found for the marked increase in ...
