Traditional parallel and serial descriptions of the visual search process are often inadequate when describing recent findings. Accordingly, literature and computational models have evolved from a dichotomous parallel and serial explanation to an account of search efficiency that is graded and continuous. In our current experiment, we replicate findings showing concurrent incremental informatio...

Background. Historically, most acute stroke clinical trials were neutral statistically, with trials typically dichotomising ordinal scales, such as the modified Rankin Scale. Studies published before 2007 have shown that preserving the ordinal nature of these scales increased statistical power. A systematic review of trials published since 2007 was conducted to reevaluate statistical methods us...

The mammalian striatum receives its main excitatory input from the two types of cortical pyramidal neurons of layer 5 of the cerebral cortex - those with only intratelencephalic connections (IT-type) and those sending their main axon to the brainstem via the pyramidal tract (PT-type). These two neurons types are present in layer 5 of all cortical regions, and thus they appear to project togethe...

The objectives of this study were to detect the presence of Vibrio cholerae in tropical estuaries (Northeastern Brazil) and to search for virulence factors in the environmental isolates. Water and sediment samples were inoculated onto a vibrio-selective medium (TCBS), and colonies with morphological resemblance to V. cholerae were isolated. The cultures were identified phenotypically using a di...

Methods We used literature search of MEDLINE, Current Contents, Cochrane Central Register of Controlled Trials, Google Scholar, Science Direct, and HighWire Press to identify relevant RCTs for our meta-analysis. We used the following search strategy and MeSH/key terms: (prone OR prone ventilation) AND (ARDS OR acute respiratory distress syndrome). We limited our search to clinical trials. No li...

Dichotomous Dichotomous variables have only two categories or levels. Variables with values such as “yes” or “no,” “present” or “absent,” “test” or “control” are dichotomous. Gender is a dichotomous variable with two values ‐ “male” and “female.” Disease status (present/absent), exposure status (present/absent), residence (urban/rural), antibiotic sensitivity (sensitive/resistant), type of bact...
