The present study investigated resource allocation, as measured by pupil dilation, in tasks measuring updating (2-Back task), inhibition (Stroop task) and switching (Number Switch task). Because each cognitive control component has unique characteristics, differences in patterns of resource allocation were expected. Pupil and behavioral data from 35 participants were analyzed. In the 2-Back tas...

In this short note, we prove that the degree-three dilation of square lattice [Formula: see text] is text]. This disproves a conjecture Dumitrescu and Ghosh. We give computer-assisted proof local-global property for uncountable set geometric graphs achieving optimal dilation.

BACKGROUND AND OBJECTIVE The feasibility and reproducibility of scanning laser polarimetry performed through dilated pupils rather than through non-dilated pupils was tested. PATIENTS AND METHODS One eye each of 36 subjects (12 normal, 12 suspected glaucoma, and 12 glaucoma) was scanned using a single GDx unit with variable corneal compensator (GDx-VCC; Laser Diagnostic Technologies, Inc., Sa...

Experiments were designed to investigate the importance of vascular endothelium in the vasomotor response to increases in flow as observed in conduit arteries (flow-dependent dilation). The diameter changes of femoral arteries (sonomicrometry) in response to increases in flow before and after endothelial damage procedures were studied in 23 dogs anesthetized with sodium pentobarbital. The funct...

BACKGROUND/AIMS Esophageal stricture is usually managed with outpatient endoscopic dilation. However, patients with food impaction or failure to thrive undergo inpatient dilation. Esophageal perforation is the most feared complication, and its risk in inpatient setting is unknown. METHODS We used National Inpatient Sample (NIS) database for 2007-2013. International Classification of Diseases,...

purpose: to evaluate pupil dilation with intracameral injection of preservative-free lidocaine 1% during phacoemulsification. methods: this interventional case series included 31 consecutive senile cataract patients scheduled for phacoemulsification and intraocular lens (iol) implantation. pupil dilation was achieved using intracameral preservative-free lidocaine 1% without any preoperative or ...

A two-dimensional direction-length framework is a pair (G, p), where G = (V ;D,L) is a graph whose edges are labeled as ‘direction’ or ‘length’ edges, and a map p from V to R. The label of an edge uv represents a direction or length constraint between p(u) and p(v). The framework (G, p) is called globally rigid if every other framework (G, q) in which the direction or length between the endvert...

A novel electronic sensor system is designed to continuously monitor the dilation of the cervix of a pregnant female approaching labour and delivery. The system is capable of wirelessly transmitting the progress of dilation to a central monitoring agency that can get in touch with the attending physician and/or the hospital of the pregnant female. Using wireless telephony, the monitoring agency...

Absfrucl-In this paper, a new technique, the multiple ripple propagation technique, is presented for mapping an h x w grid into a w x h grid such that the dilation cost is 2, i.e., such that any two neighboring nodes in the first grid are mapped onto two nodes in the second grid that are separated by a distance of at most 2. This technique is then used as a basic tool for mapping any rectangula...
