The dual theory describing the 4D Coulomb gas of point-like magnetically charged objects, which confines closed electric strings, is considered. The respective generalization of the theory of confining strings to confining membranes is further constructed. The same is done for the analogous SU(3)-inspired model. We then consider a combined model which confines both electric charges and closed s...

RESULTS Patients with a history of cannabis use presented with their first episode of ...
PURPOSE To assess whether brimonidine 0.15% alters retinal vascular autoregulation and short-term visual function in normal tension glaucoma patients who demonstrate retinal vascular dysregulation. DESIGN Nonrandomized clinical trial. METHODS In this prospective study, 46 normal tension glaucoma patients not previously treated with brimonidine underwent retinal vascular autoregulation testi...
BACKGROUND This study analyzed predictors of regular mammography performance in Korea. In addition, we determined factors affecting regular mammography performance in life-transition aged women by applying an attitude, social influence, and self-efficacy (ASE) model. MATERIALS AND METHODS Data were collected from women aged over 40 years residing in province J in Korea. The 178 enrolled subje...
OBJECTIVE To study the associations between sleep quality/quantity and performance in auditory/visual working memory tasks of different load levels. METHOD Sixty schoolchildren aged 6 to 13 years from normal school classes voluntarily participated. Actigraphy measurement was done during a typical school week for 72 consecutive hours. It was timed together with the working memory experiments t...
