OBJECTIVES To compare chart- and interview-based methods for identification of delirium. DESIGN Prospective cohort study. SETTING Two academic medical centers. PARTICIPANTS Individuals aged 70 and older undergoing major elective surgery (N = 300) (majority orthopedic surgery). MEASUREMENTS Participants were interviewed daily during hospitalization for delirium using the Confusion Assess...

In the XYZ color space, the subset of the tri-stimuli corresponding to spike-type (monochromatic) impingement of energy is the chromaticity cone (CC). Using a family of concentric spheres, we describe a nonlinear transformation over the CC and construct a bijection from the CC onto the (flat) plane. In the process, we open up the CC and view it as a chart on the plane. Because the map is a bije...

control chart is the most well-known chart to monitor the number of nonconformities per inspection unit where each sample consists of constant size. generally, the design of a control chart requires determination of sample size, sampling interval, and control limits width. optimally selecting these parameters depends on several process parameters, which have been considered from statistical and...

quality control plays an important role in increasing the product quality. fuzzy control charts are more sensitive than shewhart control chart. hence, the correct use of fuzzy control chart leads to producing better-quality products. this area is complex because it involves a large scope of industries, and information is not well organized. in this research, we provide a literature review of th...

AIM To introduce a new near-vision chart for children aged 3-5 years old and its clinical applications. METHODS The new near-vision chart which combined the Bailey-Lovie layout with a newly devised set of symmetry symbols was designed based on Weber-Fechner law. It consists of 15 rows of symmetry symbols, corresponding to a visual acuity range from 1.3 to 0.1 logMAR. The optotypes were red ag...


 A few years ago, validating proteins to see if they were good or bad was a process that took years. With the creation of Ramachandran Graph evaluates protein structures through angles φ (phi) and ψ (psi), this task became less onerous. evolution computing bioinformatics, platforms have been created generate graphs in an online manner, however, high degree usability complexity. The system...
